There are limited studies that measure the prevalence of driving under the influence of drugs (DUID) based upon impairment measures because most prevalence studies are based on drug tests. The aim of this study was to provide the first estimate of DUID prevalence in Colorado using data collected by Colorado law enforcement officers in vehicular homicide (VH) and vehicular assault (VA) cases, and reported in court records. The four research questions of this study were answered by completing independent t-tests or Mann-Whitney U tests, Pearson chi-square analyses or Fisher's exact tests, and Kruskal-Wallis tests. Seventy percent (119 out of 170) of the cases involved alcohol only and 30% (51 out of 170) involved drugs. Of the latter cases, 32 cases involved a combination of alcohol and drugs and 19 cases identified drugs only, with no alcohol. Marijuana was the most commonly cited drug (23 cases); however, it was the sole impairing substance identified in only three cases. Polydrug use was very common among DUID cases, which makes it difficult to identify which drug or drugs caused the impairment responsible for the Driving Under the Influence citation. This study revealed tha (a) drugged driving is a frequent cause of DUI citations in cases charged with VH or VA; (b) that polydrug use, rather than marijuana, is the most common cause of drugged driving in Colorado; and (c) that current warrant procedures render blood test results meaningless in cases of marijuana-impairment. States should collect and analyze DUID data to ensure legislators focus on the right DUID problems to improve biological testing for drugs, adopt more appropriate roadside testing, and enact stronger DUID laws to protect the public.

Previous studies have found that rates of homicide of children aged under one (infant homicide) are associated with rates of suicide, but not with rates of homicide. Linear regression was used to examine associations among infant homicide, homicide, and suicide in samples of regions in the United States and other countries. Infant homicide rates were significantly and independently associated in all analyses with both total homicide and total suicide rates. The epidemiological evidence supports the clinical observation that infant homicides are due to a range of causes, including maternal mental illness, but are also related to the level of serious violence within a community.

[Aggression homicide and rejection homicide: a communicative classification of homicide].

Mitterauerl, Bernhard; Griebnitz, Ernst; Rothuber, Helfried

2006-01-01

Based on a 10-year sample of homicides (n = 50), the hypothesis was tested that it is possible to differentiate between aggression and rejection homicide. The aggression homicide results from the offender/victim relationship, which is no longer accepted for some reason. In contrast, in the rejection homicide the offender radically strives for a goal which can only be reached if the victim is eliminated. Based on forensic-psychiatric expert opinions (n = 50), the case analyses yielded 31 aggression homicides and 18 rejection homicides, one case could not be classified. Aggression homicides differed significantly from the rejection homicides with regard to their main motives. Hate in quarrel (n = 8), violent occupation of the victim (n = 7), delusions (n = 5), revenge (n = 3), self-defence (n = 2), and jealousy (n = 1) characterized the aggression homicides, whereas rejection homicides were dominated by economic motives (n = 14). Two offenders intended to get rid of the victim and one offender wanted to rescue a third person. From a forensic-psychiatric point of view, the pertinent statistical data (social data, diagnosis, criminal responsibility) are reported and the significance of the differentiation between aggression homicide and rejection homicide for medico-legal or criminological case profiling and for the prognosis of the risk potential is discussed.

Homicide Followed by Suicide: A Comparison with Homicide and Suicide

Homicide-suicides are a rare yet very serious form of lethal violence which mainly occurs in partnerships and families. The extent to which homicide-suicide can be understood as being primarily a homicide or a suicide event, or rather a category of its own is examined. In total, 103 homicide-suicides were compared to 3,203 homicides and 17,751…

The authors comment on "Domestic Homicide and Homicide-Suicide: The Older Offender" by Bourget et al., who learned that after a domestic homicide in Canada, the older offender frequently commits suicide. The authors comment on the ubiquity of single homicide-suicide across cultures, the incidence of single homicide-suicide in various cultures, the common patterns and differences in single homicide-suicides across cultures, ethnic and gender differences in single homicide-suicide within different cultures, characteristics of the phenomenon of mass murder followed by suicide and ethnic differences within this type of homicide-suicide, and differences in suicidal patterns in different cultures. Suicide and suicide preceded by homicide (single or multiple) are so rare, it is currently impossible to draw any substantive conclusions about the incidence of these phenomena in various contexts; however, ideas for consideration in addressing homicide-suicide are provided.

Homicide in Chicago from 1890 to 1930: prohibition and its impact on alcohol- and non-alcohol-related homicides.

The aim of the current paper is to examine the impact of the enactment of constitutional prohibition in the United States in 1920 on total homicides, alcohol-related homicides and non-alcohol-related homicides in Chicago. Data are drawn from the Chicago Historical Homicide Project, a data set chronicling 11 018 homicides in Chicago between 1870 and 1930. Interrupted time-series and autoregression integrated moving average (ARIMA) models are employed to examine the impact of prohibition on three separate population-adjusted homicide series. All models control for potential confounding from World War I demobilization and from trend data drawn from Wesley Skogan's Time-Series Data from Chicago. Total and non-alcohol-related homicide rates increased during prohibition by 21% and 11%, respectively, while alcohol-related homicides remained unchanged. For other covariates, alcohol-related homicides were related negatively to the size of the Chicago police force and positively to police expenditures and to the proportion of the Chicago population aged 21 years and younger. Non-alcohol-related homicides were related positively to police expenditures and negatively to the size of the Chicago police force. While total and non-alcohol-related homicides in the United States continued to rise during prohibition, a finding consistent with other studies, the rate of alcohol-related homicides remained unchanged. The divergent impact of prohibition on alcohol- and non-alcohol-related homicides is discussed in relation to previous studies of homicide in this era.

Network Exposure and Homicide Victimization in an African American Community

2014-01-01

Objectives. We estimated the association of an individual’s exposure to homicide in a social network and the risk of individual homicide victimization across a high-crime African American community. Methods. Combining 5 years of homicide and police records, we analyzed a network of 3718 high-risk individuals that was created by instances of co-offending. We used logistic regression to model the odds of being a gunshot homicide victim by individual characteristics, network position, and indirect exposure to homicide. Results. Forty-one percent of all gun homicides occurred within a network component containing less than 4% of the neighborhood’s population. Network-level indicators reduced the association between individual risk factors and homicide victimization and improved the overall prediction of individual victimization. Network exposure to homicide was strongly associated with victimization: the closer one is to a homicide victim, the greater the risk of victimization. Regression models show that exposure diminished with social distance: each social tie removed from a homicide victim decreased one’s odds of being a homicide victim by 57%. Conclusions. Risk of homicide in urban areas is even more highly concentrated than previously thought. We found that most of the risk of gun violence was concentrated in networks of identifiable individuals. Understanding these networks may improve prediction of individual homicide victimization within disadvantaged communities. PMID:24228655

Most research regarding the perpetration of occupational homicide has focused on robbery-related violence; relatively little is known about the circumstances surrounding non-robbery-related occupational homicides and interventions that may prevent these events. A case series was assembled and utilized to examine occupational homicides that were and were not motivated by robbery to determine if select characteristics of the events differed according to the perpetrator's motivation for the crime and relationship to the workplace. Information on occupational homicides that occurred in North Carolina from 1994 to 2003 was abstracted from medical examiners' records and death certificates and was obtained by interviews with law-enforcement officers and from newspaper accounts (data collection occurred in 1996-2001 and 2003-2007). Each homicide was classified by motive and the perpetrator's relationship to the workplace and its employees. Characteristics of robbery-motivated and non-robbery-motivated homicides were compared. Analysis was conducted in 2006 and 2007. Most occupational homicides occurred during robbery of the workplace (64%). However, 36% of occupational homicides during the study period were not robbery-related. Strangers perpetrated 73% of robbery-related killings but only 11% of non-robbery-related homicides. Homicides unrelated to robbery occurred in several industrial sectors, including retail (28%); service (26%); and manufacturing (22%), whereas robbery-related homicides occurred overwhelmingly in retail (67%). The type of firearm used to perpetrate these killings differed by the perpetrator's relationship to the workplace. Non-robbery-related homicides constitute a meaningful proportion of occupational homicides, and the characteristics of these cases can differ from those that are robbery-related. The current system by which workplace homicides are classified could be expanded to include robbery motivation. Efforts to examine occupational-homicide-prevention strategies for non-robbery-related homicides are important.

Characteristics of homicide offenders with Schizophrenia from the Russian Federation.

It has been suggested that the characteristics of homicides committed by people with schizophrenia from regions with a high total homicide rate differ from the characteristics of homicides by people with schizophrenia from regions with low rates of homicide. Homicide offenders in the Chuvash Republic of the Russian Federation have been systematically examined for over 30 years. This study reports on a review of the documents from pre-trial psychiatric assessments and legal proceedings of all people charged with homicide offenses between 1981 and 2010 who were found to have schizophrenia. There were 133 people (120 men, 13 women) with an ICD-10 diagnosis of schizophrenia who committed a homicide offense in the 30 years of the study, including 15 repeat homicide offenders and 9 homicides with multiple victims. The odds ratio (OR) for homicide associated with schizophrenia was 13.5, 95% confidence interval (CI) (11.4-16.0). The mean age of the offenders was 34.8 (SD 9.6) and most had the paranoid subtype of schizophrenia (78%). The majority of victims were family members (51%) or acquaintances (43%). Delusions of persecution, auditory hallucinations and other positive symptoms were present in 58% of offenders at the time of the homicide. The remaining 42% exhibited negative symptoms such as emotional deficits, had antisocial attitudes or were regarded as having impaired self-control. Alcohol intoxication was reported at the time of 45% of homicides. Stabbing was the most common method and few of the homicides involved firearms. The characteristics of homicide offenders with schizophrenia from Chuvashia do not appear to differ greatly from those of homicide offenders with schizophrenia from regions with far lower rates of homicide.

Serial homicide has attracted much attention, but little empirical scientific investigation. This exploratory study reports demographic information on a large sample of serial homicide offenders (157 offenders, 608 victims), and compares a subsample of serial homicide offenses with a control group of single homicide offenses. Results show that serial homicide offenders target more women than men, and kill more strangers than family or friends. Single homicide offenders kill men and women in equal frequency, but kill family and friends more often than strangers. Serial homicide offenders kill for apparent sexual motivation more often than for any other reason, while single homicide offenders kill most often out of anger.

Rates of homicide during the first episode of psychosis and after treatment: a systematic review and meta-analysis.

PubMed

Nielssen, Olav; Large, Matthew

2010-07-01

The observation that almost half of the homicides committed by people with a psychotic illness occur before initial treatment suggests an increased risk of homicide during the first episode of psychosis. The aim of this study was to estimate the rates of homicide during the first episode of psychosis and after treatment. A systematic search located 10 studies that reported details of all the homicide offenders with a psychotic illness within a known population during a specified period and reported the number of people who had received treatment prior to the offense. Meta-analysis of these studies showed that 38.5% (95% confidence interval [CI] = 31.1%-46.5%) of homicides occurred during the first episode of psychosis, prior to initial treatment. Homicides during first-episode psychosis occurred at a rate of 1.59 homicides per 1000 (95% CI = 1.06-2.40), equivalent to 1 in 629 presentations. The annual rate of homicide after treatment for psychosis was 0.11 homicides per 1000 patients (95% CI = 0.07-0.16), equivalent to 1 homicide in 9090 patients with schizophrenia per year. The rate ratio of homicide in the first episode of psychosis in these studies was 15.5 (95% CI = 11.0-21.7) times the annual rate of homicide after treatment for psychosis. Hence, the rate of homicide in the first episode of psychosis appears to be higher than previously recognized, whereas the annual rate of homicide by patients with schizophrenia after treatment is lower than previous estimates. Earlier treatment of first-episode psychosis might prevent some homicides.

Gang homicides - five U.S. cities, 2003-2008.

PubMed

2012-01-27

Gang homicides account for a substantial proportion of homicides among youths in some U.S. cities; however, few surveillance systems collect data with the level of detail necessary to gang homicide prevention strategies. To compare characteristics of gang homicides with nongang homicides, CDC analyzed 2003-2008 data from the National Violent Death Reporting System (NVDRS) for five cities with high levels of gang homicide. This report describes the results of that analysis, which indicated that, consistent with similar previous research, a higher proportion of gang homicides than other homicides involved young adults and adolescents, racial and ethnic minorities, and males. Additionally, the proportion of gang homicides resulting from drug trade/use or with other crimes in progress was consistently low in the five cities, ranging from zero to 25%. Furthermore, this report found that gang homicides were more likely to occur with firearms and in public places, which suggests that gang homicides are quick, retaliatory reactions to ongoing gang-related conflict. These findings provide evidence for the need to prevent gang involvement early in adolescence and to increase youths' capacity to resolve conflict nonviolently.

Systematic review and meta-analysis of homicide recidivism and Schizophrenia

PubMed Central

2014-01-01

Background The aim of this study was to estimate the proportion of homicide recidivists among population studies of homicide offenders with schizophrenia. Methods Systematic review and meta-analysis of published studies of homicide associated with schizophrenia conducted in defined populations and indexed in Medline, PsychINFO, or Embase between January 1960 and November 2013. Published data was supplemented with unpublished data about recidivism obtained by personal communication from the authors of published studies of homicide and schizophrenia. Random effects meta-analysis was used to calculate a pooled estimate of the proportion of homicide recidivists. Results Three studies reported that 4.3%, 4.5%, and 10.7% of homicide offenders with schizophrenia had committed an earlier homicide. Unpublished data were obtained from the authors of 11 studies of homicide in schizophrenia published in English between 1980 and 2013. The authors of 2 studies reported a single case of homicide recidivism and the authors of 9 studies reported no cases. The rates of homicide recidivism between studies were highly heterogeneous (I-square = 79). The pooled estimate of the proportion of homicide offenders with schizophrenia who had committed an earlier homicide was 2.3% (95% CI (Confidence Interval) 0.07% to 7.2%), a figure that was not reported in any individual study. The pooled proportion of homicide recidivists from published reports was more than ten times greater (8.6%, 95% CI 5.7%-12.9%) than the pooled proportion of homicide recidivists estimated from data provided by personal communication (0.06%, 95% CI 0.02% to 1.8%). Conclusions In most jurisdictions, homicide recidivism by people with schizophrenia is less common than published reports have suggested. The reasons for the variation in the rates of homicide recidivism between studies are unclear, although in most jurisdictions long-term secure treatment and supervision after release appears to be effective in preventing homicide recidivism. A prospective study conducted in a large population or in multiple jurisdictions over a long period of time might result in a more accurate estimate the risk of a second homicide by a person with schizophrenia.

This study aims to describe child homicide perpetrators and estimate their global and regional proportion to inform prevention strategies to reduce child homicide mortality worldwide. A systematic review of 9431 studies derived from 18 databases led to the inclusion of 126 studies after double screening. All included studies reported a number or proportion of child homicides perpetrators. 169 countries and homicide experts were surveyed in addition. The median proportion for each perpetrator category was calculated by region and overall and by age groups and sex. Data were obtained for 44 countries. Overall, parents committed 56.5% (IQR 23.7-69.6) of child homicides, 58.4% (0.0-66.7) of female and 46.8% (14.1-63.8) of male child homicides. Acquaintances committed 12.6% (5.9-31.3) of child homicides. Almost a tenth (9.2% (IQR 0.0-21.9) of child homicides had missing information on the perpetrator. The largest proportion of parental homicides of children was found in high-income countries (64.2%; 44.7-71.8) and East Asia and Pacific Region (61.7%; 46.7-78.6). Parents committed the majority (77.8% (61.5-100.0)) of homicides of children under the age of 1 year. For adolescents, acquaintances were the main group of homicide perpetrators (36.9%, 6.6-51.8). There is a notable lack of studies from low-income and middle-income countries and children above the age of 1 year. Children face the highest risk of homicide by parents and someone they know. Increased investment into the compilation of routine data on child homicide, and the perpetrators of this homicide is imperative for understanding and ultimately reducing child homicide mortality worldwide.

The annual rate of homicide after treatment for psychosis was 0.11 homicides per 1000 patients (95% CI = 0.07–0.16), equivalent to 1 homicide in 9090 patients with schizophrenia per year. The rate ratio of homicide in the first episode of psychosis in these studies was 15.5 (95% CI = 11.0–21.7) times the annual rate of homicide after treatment for psychosis. Hence, the rate of homicide in the first episode of psychosis appears to be higher than previously recognized, whereas the annual rate of homicide by patients with schizophrenia after treatment is lower than previous estimates. Earlier treatment of first-episode psychosis might prevent some homicides. PMID:18990713

Patterns and Trends in Elder Homicide Across Race and Ethnicity, 1985-2009

Feldmeyer, Ben; Steffensmeier, Darrell

2014-01-01

In this report, we assess total and race/ethnicity-disaggregated patterns and temporal trends in elderly homicide (age 55-74) compared with younger age groups for the 1985-to-2009 period. To do this, we use California arrest statistics that provide annual homicide figures by race and ethnicity (including a Hispanic identifier) and by age. Major aims of our analysis are to establish whether (a) elderly homicide rates are different/similar across race/ethnic comparisons; (b) the elderly share of homicide and age-homicide distributions more generally differ across race/ethnicity; and (c) elderly rates of homicide and the share of elderly homicide relative to younger age groups is similar or different now as compared with 20 to 30 years ago. Our analysis is important and timely because some commentators have suggested that elderly homicide levels have been rising over the past one to two decades and because there is a virtual absence of research of any sort on elderly homicide trends that involve comparisons by race and ethnicity. Key findings are that elderly shares of homicide offending relative to younger ages have not increased (or decreased), that elder homicides continue to account for a small fraction of all homicides, and that these patterns persist across race/ethnicity comparisons.

Homicide-suicides, the murder of one or several individuals followed by the suicide of the perpetrator, are rare but have devastating effects on families and communities. We did a systematic review and meta-analysis of studies comparing perpetrators of homicide-suicides with perpetrators of simple homicides and suicides and examined the proportion of firearm use and its correlation with firearm availability. We searched Medline and Embase from inception to July 2012 and identified 27 eligible studies. Perpetrators of homicide-suicides were older and more likely to be male and married to or separated from their victims than perpetrator of simple homicides or suicides. Influence of alcohol and a history of domestic violence or unemployment were less prevalent in homicide-suicides than in homicides. The proportion of firearm use in homicide-suicides varied across countries and was highest in the USA, Switzerland and South Africa, followed by Australia, Canada, The Netherlands and England and Wales, with a strong correlation between the use of firearms and the level of civilian gun ownership in the country. Our results indicate that homicide-suicides represent a distinct entity, with characteristics distinguishing them both from homicides and suicides. Copyright © 2013 Elsevier Ireland Ltd.

To evaluate the National Violent Death Reporting System (NVDRS) as a surveillance system for homicides by law enforcement officers. We assessed sensitivity and positive predictive value of the NVDRS "type of death" variable against our study count of homicides by police, which we derived from NVDRS coded and narrative data for states participating in NVDRS 2005 to 2012. We compared state counts of police homicides from NVDRS, Vital Statistics, and Federal Bureau of Investigation Supplementary Homicide Reports. We identified 1552 police homicides in the 16 states. Positive predictive value and sensitivity of the NVDRS "type of death" variable for police homicides were high (98% and 90%, respectively). Counts from Vital Statistics and Supplementary Homicide Reports were 58% and 48%, respectively, of our study total; gaps varied widely by state. The annual rate of police homicide (0.24/100,000) varied 5-fold by state and 8-fold by race/ethnicity. NVDRS provides more complete data on police homicides than do existing systems. Expanding NVDRS to all 50 states and making 2 improvements we identify will be an efficient way to provide the nation with more accurate, detailed data on homicides by law enforcement.

Homicide of Strangers by People with a Psychotic Illness

Background: The homicide of strangers by people with psychosis, referred to here as “stranger homicides,” are rare and tragic events that generate adverse publicity for mental health services and have resulted in significant changes in mental health policy and law. Aim: To estimate the incidence of stranger homicides, using data from previously published studies, and to compare the characteristics of psychotic offenders who killed strangers with the characteristics of those who killed a close relative. Method: Meta-analysis of the population-based studies of homicide by persons suffering from a psychosis in which the number of subjects who killed strangers was also reported. Characteristics of stranger homicide and family homicide offenders were examined in a multicenter case–control study of homicide during psychotic illness in four high-income countries. Results: A pooled estimate of 1 stranger homicide per 14.3 million people per year (95% confidence interval, 1 in 18.9 million to 1 in 11.5 million people per year) was calculated by meta-analysis of 7 studies. The characteristics of the 42 stranger homicide offenders from New South Wales [NSW], Quebec and Eastern Ontario, Finland, and the Netherlands were identified. Twenty seven (64%) of these had never previously received treatment with antipsychotic medication. The stranger homicide offenders were more likely to be homeless, have exhibited antisocial conduct, and had fewer negative symptoms than those who killed family members. The victims of stranger homicide were mostly adult males and the homicides rarely occurred in the victim’s home or workplace. Conclusions: Stranger homicide in psychosis is extremely rare and is even rarer for a patient who has received treatment with antipsychotic medication. A lack of distinguishing characteristics of stranger homicide offenders and an extremely low base rate of stranger-homicide suggests that risk assessment of patients known to have a psychotic illness will be of little assistance in the prevention of stranger homicides.

We conducted a retrospective national mortuary based study to identify all adult female homicides (18 years and older) and all child homicides (boys and girls < 18 years) in 2009 in a randomly selected, proportionate sample of mortuaries. Victim, perpetrator and crime data were collected in three processes: from the mortuary register, the autopsy report and from police with the identification of sexual homicides validated across the data collection processes. Among the 2670 (95% CI: 2311-2979) adult women killed in 2009, 494 (95% CI: 406-574) were identified as sexual homicides which was 19.8% (95% CI: 17.6-22.0) of all adult female homicides and among 1277 (95% CI: 1091-1462) children killed in SA, sexual homicides were found in 104 (95% CI: 77-132) of the child homicides which was 8.7% (95% CI: 10.9-11.2%) of these murders. Strangulation was the most common cause of death for both children and adult females. A distinct age and sex pattern was found among children with only 1% boy child death identified as a sexual homicide and 92% of all the child sexual homicides were among girls. Strangulation was the most common manner of death among children (35.5%) and perpetrators were seldom strangers. However, no difference in the proportion of convictions between the sexual homicides and non-sexual homicides were found for both adult females and children. Rape homicide is not a rare event in South Africa, with one in five female homicides and nearly one in ten child homicides identified with an associated sexual crime. These high prevalences are amongst the highest levels reported in the literature with our study among the few reporting on the epidemiology of child sexual homicide. Reducing mortality is an important policy goal for South Africa and for the rest of the world and the prevention of female and child homicide is an important part of attaining this goal.

U.S. spousal homicide rates by racial composition of marriage.

Roberts, John M

2015-09-01

American spousal homicide rates persistently and substantially vary by racial composition of the married couple. Analyses examined different racial couple types' spousal homicide rates in light of nonspousal homicide victimization and offending rates and couple types' average social, demographic, and economic characteristics. Analyses used 2003 to 2007 spousal homicide data from Supplementary Homicide Reports for which missing data have been multiply imputed. Current Population Survey data provided estimates of the number and average characteristics of different couple types. Log-linear models related couple types' differing spousal homicide rates to different race-sex groups' general rates of homicide victimization and offending and couple types' average characteristics. Among couple types with at least 50,000 couples, annual rates of male-on-female spousal homicide ranged from 0.95 to 8.76 per 100,000 couples; for female-on-male spousal homicide, this range was 0.13 to 2.29. Rates somewhat reflect different race-sex groups' nonspousal homicide activity, but with greater gender disparity and an excess of spousal homicide in some couple types. The association between victim's and offender's race is parsimoniously described by models using couple types' average characteristics (proportion with female's education exceeding the male's, proportion in central cities, and relative frequency). General homicidal-violence reduction strategies may partly apply to spousal homicide, but specifically targeted efforts are required too. Interventions must address different couple types' particular social, economic, and cultural experiences. Copyright © 2015 Elsevier Inc. All rights reserved.

Adolescent homicide victimization in Johannesburg, South Africa: incidence and epidemiological characteristics (2001-2009).

PubMed

Swart, Lu-Anne; Seedat, Mohamed; Nel, Juan

2016-09-01

This study describes the incidence and epidemiological characteristics of adolescent homicides (15-19 years) in Johannesburg, South Africa. A retrospective population-based study was conducted on cases drawn from the National Injury Mortality Surveillance System. A total of 590 adolescent homicides were registered for 2001-2009 corresponding to an average annual homicide rate of 23.4/100,000. The average annual rate was 39.8/100,000 for males and 7.9/100,000 for females. Black and coloured adolescents had the highest homicide rates. There was a considerable decline in the firearm homicide rates over the study period. In contrast, sharp instrument and blunt force homicides increased. Public places were the predominant scenes for male deaths, while female homicides occurred primarily in residential locations. Most male homicides took place over weekend nights. Alcohol was a prominent feature of homicides. The high homicide rates reported in this study underscore the need to develop interventions directed specifically at adolescents. Prevention efforts are required to pay particular attention to black and coloured adolescent males, and to address the availability of weapons and alcohol use among adolescents.

Prostitute women have the highest homicide victimization rate of any set of women ever studied. We analyzed nine diverse homicide data sets to examine the extent, trends, and perpetrators of prostitution-related homicide in the United States. Most data sources substantially under-ascertained prostitute homicides. As estimated from a conservative capture-recapture analysis, 2.7% of female homicide victims in the United States between 1982 and 2000 were prostitutes. Frequencies of recorded prostitute and client homicides increased substantially in the late 1980s and early 1990s; nearly all of the few observed pimp homicides occurred before the late 1980s. These trends may be linked to the rise of crack cocaine use. Prostitutes were killed primarily by clients, clients were killed mainly by prostitutes, and pimps were killed predominantly by pimps. Another conservative estimate suggests that serial killers accounted for 35% of prostitute homicides. Proactive surveillance of, and evidence collection from, clients and prostitutes might enhance the investigation of prostitution-related homicide.

The purpose of this study was to examine non-robbery-related occupational homicides in the retail industry from 2003 to 2008. Data were abstracted from the Census of Fatal Occupational Injuries. Motive (robbery- or non-robbery-related) and workplace violence (WPV) typology (Type I-IV) were assigned using narrative text fields. Non-robbery-related homicide rates were calculated and compared among WPV types, demographic characteristics, and occupation. Twenty-eight percent of homicides that occurred in the retail industry were non-robbery-related. The leading event associated with non-robbery-related homicides was Type II (perpetrated by customers) (34%), followed by Type IV (perpetrated by personal relationship) (31%). The majority of homicides were due to arguments (50%). Security guards and workers in drinking establishments had the highest homicide rates per 100,000 workers (14.3 and 6.0, respectively). Non-robbery-related homicides comprised a meaningful proportion of workplace homicides in the retail industry. Research is needed to develop strategies to prevent non-robbery-related homicides specifically. © 2013 Wiley Periodicals, Inc.

Gun availability and use of guns for suicide, homicide, and murder in Canada.

2004-04-01

A reliability check of Lester's (2000b) 1970-1995 time series that examined associations between the availability of firearms and their use for homicide and suicide in Canada. For the period 1974 to 1999, the relative availability of firearms as measured by the rate of accidental death from firearms and the average of the percentages of suicides + homicides using firearms was positively associated with the rate of homicide by firearms but not negatively associated with the rate of homicide by all other methods, and positively associated with the rate of suicide by firearms and negatively associated with the rate of suicide by all other methods. Correlations for the homicide versus murder rates, homicide rate using guns versus murder rate using guns, and homicide rate by all other methods versus murder rate by all other methods were very similar. There was a decrease over time of total suicide and homicide rates and firearm suicide and homicide rates, and with a slight indication of substitution of other methods for suicide.

Objective. To evaluate the National Violent Death Reporting System (NVDRS) as a surveillance system for homicides by law enforcement officers. Methods. We assessed sensitivity and positive predictive value of the NVDRS “type of death” variable against our study count of homicides by police, which we derived from NVDRS coded and narrative data for states participating in NVDRS 2005 to 2012. We compared state counts of police homicides from NVDRS, Vital Statistics, and Federal Bureau of Investigation Supplementary Homicide Reports. Results. We identified 1552 police homicides in the 16 states. Positive predictive value and sensitivity of the NVDRS “type of death” variable for police homicides were high (98% and 90%, respectively). Counts from Vital Statistics and Supplementary Homicide Reports were 58% and 48%, respectively, of our study total; gaps varied widely by state. The annual rate of police homicide (0.24/100 000) varied 5-fold by state and 8-fold by race/ethnicity. Conclusions. NVDRS provides more complete data on police homicides than do existing systems. Policy Implications. Expanding NVDRS to all 50 states and making 2 improvements we identify will be an efficient way to provide the nation with more accurate, detailed data on homicides by law enforcement. PMID:26985611

Homicide is one of the leading causes of death for women aged ≤44 years.* In 2015, homicide caused the death of 3,519 girls and women in the United States. Rates of female homicide vary by race/ethnicity (1), and nearly half of victims are killed by a current or former male intimate partner (2). To inform homicide and intimate partner violence (IPV) prevention efforts, CDC analyzed homicide data from the National Violent Death Reporting System (NVDRS) among 10,018 women aged ≥18 years in 18 states during 2003-2014. The frequency of homicide by race/ethnicity and precipitating circumstances of homicides associated with and without IPV were examined. Non-Hispanic black and American Indian/Alaska Native women experienced the highest rates of homicide (4.4 and 4.3 per 100,000 population, respectively). Over half of all homicides (55.3%) were IPV-related; 11.2% of victims of IPV-related homicide experienced some form of violence in the month preceding their deaths, and argument and jealousy were common precipitating circumstances. Targeted IPV prevention programs for populations at disproportionate risk and enhanced access to intervention services for persons experiencing IPV are needed to reduce homicides among women.

Background Violence that leads to homicide results in an extreme financial and emotional burden on society. Juveniles who commit homicide are often tried in adult court and typically spend the majority of their lives in prison. Despite the enormous costs associated with homicidal behavior, there have been no serious neuroscientific studies examining youth who commit homicide. Methods Here we use neuroimaging and voxel-based morphometry to examine brain gray matter in incarcerated male adolescents who committed homicide (n = 20) compared with incarcerated offenders who did not commit homicide (n = 135). Two additional control groups were used to understand further the nature of gray matter differences: incarcerated offenders who did not commit homicide matched on important demographic and psychometric variables (n = 20) and healthy participants from the community (n = 21). Results Compared with incarcerated adolescents who did not commit homicide (n = 135), incarcerated homicide offenders had reduced gray matter volumes in the medial and lateral temporal lobes, including the hippocampus and posterior insula. Feature selection and support vector machine learning classified offenders into the homicide and non-homicide groups with 81% overall accuracy. Conclusions Our results indicate that brain structural differences may help identify those at the highest risk for committing serious violent offenses. PMID:24936430

Child homicides are rare but serious crimes. In this study the homicide rate and the development in the crime pattern will be investigated. The investigation is retrospective and comprises the 34 years during which the Institute of Forensic Medicine in Odense has existed. During this period 41 children under the age of 15 were killed in 30 episodes. The most frequent method of homicide was manual strangulation, and the second most frequent was blunt violence. It is demonstrated that the incidence of child homicide has decreased considerably compared to a previous investigation comprising all of Denmark. By far the largest decrease is in homicides committed by women against their own children, which have often been followed by suicide (family homicides). The decrease in family homicides committed by men is much less. Today men commit family homicides 8 times as frequently as women in the area under investigation. A possible explanation for the decreasing number of homicides committed by women against their own children is the decreased use of gas for cooking, whereby a frequent homicide method disappeared, and by improved socio-economic life conditions and gender balance. Men are now responsible for the majority of family homicides. Preventative measures for men in socially traumatic situations such as a divorce are recommended.

A 30-year study of homicide recidivism and schizophrenia.

A second homicide by a released mentally ill person is a potentially avoidable tragedy that can reduce the prospects of conditional release for other mentally ill offenders. The aim of this study was to compare the clinical and criminological features of single and recidivist homicide offenders with schizophrenia from the Chuvash Republic of the Russian Federation. Data were extracted from the criminal and clinical records of all people with schizophrenia who had been convicted of a homicide in the Chuvash Republic at any time between 1 January 1981 and 31 December 2010. Those convicted of a second homicide offence during the 30 years of the study were compared with those convicted of a single homicide. Sixteen (10.7%) of 149 homicide offenders with schizophrenia had committed a previous homicide. The 16 recidivists included nine offenders who were diagnosed with schizophrenia at the time of their first homicide (after January 1981), three who were diagnosed with schizophrenia only after the first homicide and four who had already been diagnosed with schizophrenia at the time of a pre-1981 homicide. Time at risk for recidivists and non-recidivists differed, but the average time back in the community for the non-recidivists just exceeded the average time to second homicide for the recidivists. All the recidivists were men. Living in a rural area and dissocial personality traits were associated with homicide recidivism. In the Chuvash republic, most of the repeat homicide offences by people with schizophrenia were committed by people residing in rural areas with less access to psychiatric services, which provides indirect evidence for the efficacy of ongoing treatment and supervision in preventing repeat homicides. This area of study is, however, limited by the small numbers of cases and the long follow-up required. International collaborative studies are indicated to provide a more accurate estimate of the rate of recidivist homicide in schizophrenia. Copyright © 2013 John Wiley & Sons, Ltd.

The annual number of homicide convictions in England and Wales is increasing. Previous studies have highlighted the aetiological role of alcohol and drugs in homicide. To examine rates of alcohol and drug misuse and dependence in people convicted of homicide; the role of alcohol and drugs in the offence; the social and clinical characteristics of alcohol- and drug-related homicides; and the social and clinical characteristics of patients with dual diagnosis who commit homicide. A national clinical survey based on a 3-year (1996-9) consecutive sample of people convicted of homicide in England and Wales. Information on rates of alcohol and drug misuse/dependence, the role of alcohol and drugs in the offence and social and clinical characteristics of perpetrators were collected from psychiatric reports prepared for the court in homicide convictions. Detailed clinical information was gathered from questionnaires completed by mental health teams for those in contact with mental health services. Of the 1594 homicide perpetrators, more than one-third (42%) occurred in people with a history of alcohol misuse or dependence and 40% in people with a history of drug misuse or dependence. Alcohol or drug misuse played a contributory role in two-fifths of homicides. Alcohol played a major role in 52 (6%) and a minor role in 364 (39%) homicides. Drugs played a major role in six (1%) and a minor role in 138 (14%) homicides. Forty-two homicides (17%) were committed by patients with severe mental illness and substance misuse. Alcohol- and drug-related homicides were generally associated with male perpetrators who had a history of violence, personality disorders, mental health service contact and with stranger victims. Substance misuse contributes to the majority of homicides in England and Wales. A public health approach to homicide would highlight alcohol and drugs before severe mental illness.

It is possible that sexually driven homicides are the consequence of sexual deviation, but more often than not the main cause of such homicides stems from a non-paraphilic person's emotional component. It is known that homicides which involve multiple stabbing are very often the result of the assailant's highly expressed affect. This study tries to establish whether such homicides are essentially related to the sexual motives of the murderer. This paper is conducted through a retrospective autopsy study that includes 766 cases of homicides. These were reviewed and analysed according to the motive of the homicide, as well as by method, age, and gender of the victim, and the relationship between the victim and the assailant. The motives of homicides are classified as non-sexual and sexual, including homicides related to rape, jealousy, amorous affairs outside of an established relationship, deviant sexual behaviour of psychiatric patients, paraphilia, and disturbed emotional relationships between the victim and the assailant. Cases include both hetero- and homosexual relationships. Multiple stabbing occurs significantly more frequently in sex-related homicides (≥ 3 stab wounds) than in other homicide types. When the criteria for multiple stabbing are changed (≥ 4, 5, or 25 stab wounds), the percentage of sex-related homicides rises in every group in relation to the increased number of wounds. Sensitivity and specificity are represented by ROC curves for 3, 5 and 7 stab wounds. The correlation coefficients between multiple stabbing and sex-related homicides regarding gender are all near 0.9. For female victims, all homicides committed by 25 and more stab wounds were found to be sex-related. Statistically, jealousy was the most frequent motive for sex-related multiple stabbing homicides. Regardless of age, homicides involving multiple stabbings should be considered sex-related, especially when the victim is female.

Objective This study aims to describe child homicide perpetrators and estimate their global and regional proportion to inform prevention strategies to reduce child homicide mortality worldwide. Design A systematic review of 9431 studies derived from 18 databases led to the inclusion of 126 studies after double screening. All included studies reported a number or proportion of child homicides perpetrators. 169 countries and homicide experts were surveyed in addition. The median proportion for each perpetrator category was calculated by region and overall and by age groups and sex. Results Data were obtained for 44 countries. Overall, parents committed 56.5% (IQR 23.7–69.6) of child homicides, 58.4% (0.0–66.7) of female and 46.8% (14.1–63.8) of male child homicides. Acquaintances committed 12.6% (5.9–31.3) of child homicides. Almost a tenth (9.2% (IQR 0.0–21.9) of child homicides had missing information on the perpetrator. The largest proportion of parental homicides of children was found in high-income countries (64.2%; 44.7–71.8) and East Asia and Pacific Region (61.7%; 46.7–78.6). Parents committed the majority (77.8% (61.5–100.0)) of homicides of children under the age of 1 year. For adolescents, acquaintances were the main group of homicide perpetrators (36.9%, 6.6–51.8). There is a notable lack of studies from low-income and middle-income countries and children above the age of 1 year. Conclusion Children face the highest risk of homicide by parents and someone they know. Increased investment into the compilation of routine data on child homicide, and the perpetrators of this homicide is imperative for understanding and ultimately reducing child homicide mortality worldwide.

To examine the relation of "shall-issue" laws, in which permits must be issued if requisite criteria are met; "may-issue" laws, which give law enforcement officials wide discretion over whether to issue concealed firearm carry permits or not; and homicide rates. We compared homicide rates in shall-issue and may-issue states and total, firearm, nonfirearm, handgun, and long-gun homicide rates in all 50 states during the 25-year period of 1991 to 2015. We included year and state fixed effects and numerous state-level factors in the analysis. Shall-issue laws were significantly associated with 6.5% higher total homicide rates, 8.6% higher firearm homicide rates, and 10.6% higher handgun homicide rates, but were not significantly associated with long-gun or nonfirearm homicide. Shall-issue laws are associated with significantly higher rates of total, firearm-related, and handgun-related homicide.

Homicides by mentally ill persons have led to political concerns about deinstitutionalisation. To provide accurate information about the contribution of mental illness to homicide rates. Retrospective study of homicide in New Zealand from 1970 to 2000, using data from government sources. 'Mentally abnormal homicide'perpetrators were defined as those found unfitto stand trial, not guilty by reason of insanity, convicted and sentenced to psychiatric committal, or convicted of infanticide. Group and time trends were analysed. Mentally abnormal homicides constituted 8.7% of the 1498 homicides. The annual rate of such homicides was 1.3 per million population, static over the period. Total homicides increased by over 6% per year from 1970 to 1990, then declined from 1990 to 2000. The percentage of all homicides committed by the mentally abnormal group fell from 19.5% in 1970 to 5.0% in 2000. Ten percent of perpetrators had been admitted to hospital during the month before the offence; 28.6% had had no prior contact with mental health services. Victims were most commonly known to the perpetrator (74%). Deinstitutionalisation appears not to be associated with an increased risk of homicide by people who are mentally ill.

To examine the prevalence of PTSD following homicide and investigate the relationship between PTSD from past traumas, defense styles and PTSD following homicide and psychiatric co-morbidity. 167 male homicide perpetrators participated in the study and completed the Posttraumatic Stress Diagnostic Scale, the General Health Questionnaire-28 and the Defense Styles Questionnaire. 45% met the criteria for PTSD following homicide and 55% for no-PTSD. With the number of times for imprisonment adjusted, regression analyses showed that immature defense style was associated with PTSD following homicide with the severity of PTSD from past traumas as a moderator. Neurotic and immature defense styles and PTSD from past trauma were significantly and independently associated with psychiatric co-morbidity. Homicide perpetrators could develop PTSD following homicide. The severity of PTSD from past traumas could affect PTSD following homicide and other psychological problems, and influence the effect of using immature defense against PTSD from homicide. Past trauma, immature and neurotic defense styles had a unique and specific pattern of influence on psychological symptoms, other than trauma symptoms.

Sexual homicides of women and children are extreme forms of violence against women and children and are located within the broader context of gender inequality and social norms that condone sexual violence and gender based violence against women and children. The aim of this study is to describe the prevalence and characteristics of sexual homicide of women and children nationally in South Africa. Methods We conducted a retrospective national mortuary based study to identify all adult female homicides (18 years and older) and all child homicides (boys and girls < 18 years) in 2009 in a randomly selected, proportionate sample of mortuaries. Victim, perpetrator and crime data were collected in three processes: from the mortuary register, the autopsy report and from police with the identification of sexual homicides validated across the data collection processes. Findings Among the 2670 (95% CI: 2311–2979) adult women killed in 2009, 494 (95% CI: 406–574) were identified as sexual homicides which was 19.8% (95% CI: 17.6–22.0) of all adult female homicides and among 1277 (95% CI: 1091–1462) children killed in SA, sexual homicides were found in 104 (95% CI: 77–132) of the child homicides which was 8.7% (95% CI: 10.9–11.2%) of these murders. Strangulation was the most common cause of death for both children and adult females. A distinct age and sex pattern was found among children with only 1% boy child death identified as a sexual homicide and 92% of all the child sexual homicides were among girls. Strangulation was the most common manner of death among children (35.5%) and perpetrators were seldom strangers. However, no difference in the proportion of convictions between the sexual homicides and non-sexual homicides were found for both adult females and children. Conclusion Rape homicide is not a rare event in South Africa, with one in five female homicides and nearly one in ten child homicides identified with an associated sexual crime. These high prevalences are amongst the highest levels reported in the literature with our study among the few reporting on the epidemiology of child sexual homicide. Reducing mortality is an important policy goal for South Africa and for the rest of the world and the prevention of female and child homicide is an important part of attaining this goal.

South Africa has continued to receive increasing attention due to unprecedented high levels of violence. Homicide-related violence accounts for a significant proportion of unnatural deaths and contributes significantly to loss of years of expected life. We investigated levels and factors associated with homicide-related deaths and identify communities with excessively high homicide risk in a typical rural South African population. Data drawn from verbal autopsies conducted on all deaths recorded during annual demographic and health surveillance in KwaZulu Natal, South Africa were used to derive the cumulative probability of death from homicide over a nine-year period (2000-2008). Weibull regression methods were used to investigate factors associated with homicide deaths. A Kulldorff spatial scan statistic was used to identify spatial clusters of homicide-related deaths. With 536 homicide-related deaths, and a median seven years of follow-up, the study found an overall homicide incidence rate of 66 deaths per 100, 000 person-years of observation (PYOs) (95 % CI 60-72) for the period under study. Death related to the use of firearms was the leading reported method of homicide (65 %) and most deaths occurred over weekends (43 %). Homicides are the second-most common cause of death in men aged 25-34 after HIV-related deaths (including TB) in this community, at 210 deaths per 100,000 PYOs, and was highest among 55-64 year old women, at 78 deaths per 100,000 PYOs. Residency status, age, socioeconomic status, and highest education level attained independently predicted the risk of homicide death. The spatial distribution of homicide deaths was not homogenous and the study identified two clear geographical clusters with significantly elevated homicide risk. The high rates of homicide observed in this typical rural South African population - particularly among men - underscore the need for urgent interventions to reduce this tragic and theoretically preventable loss of life in this population and similar South African settings.

In 2005, Florida amended its self-defense laws to provide legal immunity to individuals using lethal force in self-defense. The enactment of "stand your ground" laws in the United States has been controversial and their effect on rates of homicide and homicide by firearm is uncertain. To estimate the impact of Florida's stand your ground law on rates of homicide and homicide by firearm. Using an interrupted time series design, we analyzed monthly rates of homicide and homicide by firearm in Florida between 1999 and 2014. Data were collected from the Wide-ranging Online Data for Epidemiologic Research (WONDER) web portal at the Centers for Disease Control and Prevention. We used seasonally adjusted segmented Poisson regression models to assess whether the onset of the law was associated with changes in the underlying trends for homicide and homicide by firearm in Florida. We also assessed the association using comparison states without stand your ground laws (New York, New Jersey, Ohio, and Virginia) and control outcomes (all suicides and suicides by firearm in Florida). October 1, 2005, the effective date of the law, was used to define homicides before and after the change. Monthly rates of homicide, firearm-related homicide, suicide, and suicide by firearm in Florida and the 4 comparison states. Prior to the stand your ground law, the mean monthly homicide rate in Florida was 0.49 deaths per 100 000 (mean monthly count, 81.93), and the rate of homicide by firearm was 0.29 deaths per 100 000 (mean monthly count, 49.06). Both rates had an underlying trend of 0.1% decrease per month. After accounting for underlying trends, these results estimate that after the law took effect there was an abrupt and sustained increase in the monthly homicide rate of 24.4% (relative risk [RR], 1.24; 95%CI, 1.16-1.33) and in the rate of homicide by firearm of 31.6% (RR, 1.32; 95% CI, 1.21-1.44). No evidence of change was found in the analyses of comparison states for either homicide (RR, 1.06; 95% CI, 0.98-1.13) or homicide by firearm (RR, 1.08; 95% CI, 0.99-1.17). Furthermore, no changes were observed in control outcomes such as suicide (RR, 0.99; 95% CI, 0.94-1.05) and suicide by firearm (RR, 0.98; 95% CI, 0.91-1.06) in Florida between 2005 and 2014. The implementation of Florida's stand your ground self-defense law was associated with a significant increase in homicides and homicides by firearm but no change in rates of suicide or suicide by firearm.

Approximately 10% of convicted homicide perpetrators in England and Wales have symptoms of mental illness at the time of homicide. The prevalence among perpetrators of adult domestic homicide is unclear. The study was a consecutive case series of all convicted adult domestic homicide perpetrators in England and Wales between 1997 and 2008. Sociodemographic, clinical, and offense characteristics were gathered from the United Kingdom Home Office, the Police National Computer, psychiatric court reports, and, for psychiatric patients, questionnaires completed by supervising clinicians. A total of 1,180 perpetrators were convicted of intimate partner homicide, and 251 were convicted of homicide of an adult family member. Fourteen percent of perpetrators of intimate partner homicide and 23% of perpetrators of adult family homicide had been in contact with mental health services in the year before the offense; 20% of intimate partner homicide perpetrators and 34% of adult family homicide perpetrators had symptoms of mental illness at the time of offense. Perpetrators with symptoms of mental illness at the time of offense were less likely than perpetrators without symptoms to have previous violence convictions or history of alcohol abuse. A significant minority of adult domestic homicide perpetrators had symptoms of mental illness at the time of the homicide. Most perpetrators, including those with mental illnesses, were not in contact with mental health services in the year before the offense. Risk reduction could be achieved through initiatives that encourage individuals with mental health problems to access mental health services and that develop closer interagency working, including between mental health services, police, social services, and domestic violence services.

We sought to estimate the effect of Connecticut's implementation of a handgun permit-to-purchase law in October 1995 on subsequent homicides. Using the synthetic control method, we compared Connecticut's homicide rates after the law's implementation to rates we would have expected had the law not been implemented. To estimate the counterfactual, we used longitudinal data from a weighted combination of comparison states identified based on the ability of their prelaw homicide trends and covariates to predict prelaw homicide trends in Connecticut. We estimated that the law was associated with a 40% reduction in Connecticut's firearm homicide rates during the first 10 years that the law was in place. By contrast, there was no evidence for a reduction in nonfirearm homicides. Consistent with prior research, this study demonstrated that Connecticut's handgun permit-to-purchase law was associated with a subsequent reduction in homicide rates. As would be expected if the law drove the reduction, the policy's effects were only evident for homicides committed with firearms.

While homicide perpetrated by juveniles is a relatively rare occurrence, between 2010 and 2014, approximately 7%–8% of all murders involved a juvenile offender. Unfortunately, few studies have prospectively examined the predictors of homicide offending, with none examining first-time murder among a sample of adjudicated male and female youth. The current study employed data on 5908 juvenile offenders (70% male, 45% Black) first arrested at the age of 12 or younger to prospectively examine predictors of an arrest for homicide/attempted homicide by the age of 18. Among these early-onset offenders, males, Black youth, those living in households with family members with a history of mental illness, those engaging in self-mutilation, and those with elevated levels of anger/aggression (all measured by age 13) were more likely to be arrested for homicide/attempted homicide by age 18. These findings add to the scant scientific literature on the predictors of homicide, and illustrate potential avenues for intervention. PMID:28212340

Background The purpose of this study was to examine non-robbery-related occupational homicides in the retail industry from 2003 to 2008. Methods Data were abstracted from the Census of Fatal Occupational Injuries. Motive (robbery- or non-robbery-related) and workplace violence (WPV) typology (Type I–IV) were assigned using narrative text fields. Non-robbery-related homicide rates were calculated and compared among WPV types, demographic characteristics, and occupation. Results Twenty-eight percent of homicides that occurred in the retail industry were non-robbery-related. The leading event associated with non-robbery-related homicides was Type II (perpetrated by customers) (34%), followed by Type IV (perpetrated by personal relationship) (31%). The majority of homicides were due to arguments (50%). Security guards and workers in drinking establishments had the highest homicide rates per 100,000 workers (14.3 and 6.0, respectively). Conclusions Non-robbery-related homicides comprised a meaningful proportion of workplace homicides in the retail industry. Research is needed to develop strategies Periodicals, Inc. PMID:24248892

Death review teams are a common method for assessing preventable deaths, yet they rarely review adult homicides and do not typically include community members. Academic-community partnerships can enhance public health research by encouraging translation of research into practice and support a data-driven approach to improve community health and well-being. We describe the Pittsburgh Homicide Review Group, a community-partnered initiative to prevent future homicides through data review and community dialogue. Group members reviewed all 42 Pittsburgh 2012 homicides informed by three primary data sources: publicly available data, local service databases, and community outreach resources. Thirty-two individuals representing relevant county agencies and community groups participated in eight reviews. Data sharing among partners resulted in a comprehensive understanding of the context of homicides. Review meetings supported a collective discussion around potential contributing factors to homicides, intervention implications, and recommendations. Academic-community homicide review partnerships are a productive approach to inform homicide prevention and interventions that are relevant to communities and should be implemented widely.

There are few studies of the relationship between mental disorder and homicide offences from regions with high rates of homicide. We examined the characteristics and psychiatric diagnoses of homicide offenders from the Chuvash Republic of the Russian Federation, a region of Russia with a high total homicide rate. In the 30 years between 1981 and 2010, 3414 homicide offenders were the subjected to pre-trial evaluations by experienced psychiatrists, almost half of whom (1596, 46.7%) met the international classification of diseases (ICD) 10 criteria for at least one mental disorder. The six most common individual diagnoses were alcohol dependence (15.9%), acquired organic mental disorder (7.3%), personality disorder (7.1%), schizophrenia (4.4%) and intellectual disability (3.6%). More than one disorder was found in 7.4% of offenders and alcohol dependence was the most frequently diagnosed co-morbid disorder. One in ten offenders were found to be not criminally responsible for their actions. Few homicides involved the use of substances other than alcohol, and firearms were used in 1.6% of homicides. The finding that people with mental disorders other than psychosis committed a high proportion of homicides in a region with a high rate of homicide, suggests that people with mental disorders are vulnerable to similar sociological factors to those that contribute to homicide offences by people who do not have mental disorder.

Background Taxicab drivers historically have had one of the highest work-related homicide rates of any occupation. In 2010 the taxicab driver homicide rate was 7.4 per 100,000 drivers, compared to the overall rate of 0.37 per 100,000 workers. Purpose Evaluate the effectiveness of taxicab security cameras and partitions on citywide taxicab driver homicide rates. Methods Taxicab driver homicide rates were compared in 26 major cities in the U.S. licensing taxicabs with security cameras (n=8); bullet-resistant partitions (n=7); and cities where taxicabs were not equipped with either security cameras or partitions (n=11). News clippings of taxicab driver homicides and the number of licensed taxicabs by city were used to construct taxicab driver homicide rates spanning 15 years (1996–2010). Generalized estimating equations were constructed to model the Poisson-distributed homicide rates on city-specific safety equipment installation status, controlling for city homicide rate and the concurrent decline of homicide rates over time. Data were analyzed in 2012. Results Cities with cameras experienced a threefold reduction in taxicab driver homicides compared with control cities (RR=0.27; 95% CI=0.12, 0.61; p=0.002). There was no difference in homicide rates for cities with partitions compared with control cities (RR=1.15; 95% CI=0.80, 1.64; p=0.575). Conclusions Municipal ordinances and company policies mandating security cameras appear to be highly effective in reducing taxicab driver deaths due to workplace violence. PMID:23790983

Although the association between alcohol and homicide is well documented, there has been no recent study of alcohol involvement in homicide victimization in U.S. states. The objective of this article was to determine the prevalence of alcohol involvement in homicide victimization and to identify socio demographic and other factors associated with alcohol involvement in homicide victimization. Data from homicide victims with a reported blood alcohol content (BAC) level were analyzed from 17 states from 2010 to 2012 using the National Violent Death Reporting System. Logistic regression was used to investigate factors associated with the odds of homicide victims having a BAC ≥ 0.08%. Among all homicide victims, 39.9% had a positive BAC including 13.7% with a BAC between 0.01% and 0.79% and 26.2% of victims with a BAC ≥ 0.08%. Males were twice as likely as females to have a BAC ≥ 0.08% (29.1% vs. 15.2%; p < 0.001). Characteristics that were independent predictors of homicide victims having a BAC ≥ 0.08 included male sex, American Indian/Alaska Native race, Hispanic ethnicity, history of intimate partner violence, and nonfirearm homicides. Alcohol is present in a substantial proportion of homicide victims in the United States, with substantial variation by state, demographic, and circumstantial characteristics. Future studies should explore the relationships between state-level alcohol policies and alcohol involvement among perpetrators and victims of homicide.

2014-03-01

We assessed the effectiveness of South Africa's Firearm Control Act (FCA), passed in 2000, on firearm homicide rates compared with rates of nonfirearm homicide across 5 South African cities from 2001 to 2005. We conducted a retrospective population-based study of 37 067 firearm and nonfirearm homicide cases. Generalized linear models helped estimate and compare time trends of firearm and nonfirearm homicides, adjusting for age, sex, race, day of week, city, year of death, and population size. There was a statistically significant decreasing trend regarding firearm homicides from 2001, with an adjusted year-on-year homicide rate ratio of 0.864 (95% confidence interval [CI] = 0.848, 0.880), representing a decrease of 13.6% per annum. The year-on-year decrease in nonfirearm homicide rates was also significant, but considerably lower at 0.976 (95% CI = 0.954, 0.997). Results suggest that 4585 (95% CI = 4427, 4723) lives were saved across 5 cities from 2001 to 2005 because of the FCA. Strength, timing and consistent decline suggest stricter gun control mediated by the FCA accounted for a significant decrease in homicide overall, and firearm homicide in particular, during the study period.

Association between Firearm Laws and Homicide in Urban Counties.

Laws related to the sale, use, and carrying of firearms have been associated with differences in firearm homicide rates at the state level. Right-to-carry (RTC) and stand your ground (SYG) laws are associated with increases in firearm homicide; permit-to-purchase (PTP) laws and those prohibiting individuals convicted of violent misdemeanors (VM) have been associated with decreases in firearm homicide. Evidence for the effect of comprehensive background checks (CBC) not tied to PTP is inconclusive. Because firearm homicide tends to concentrate in urban areas, this study was designed to test the effects of firearm laws on homicide in large, urban U.S. counties. We conducted a longitudinal study using an interrupted time series design to evaluate the effect of firearm laws on homicide in large, urban U.S. counties from 1984 to 2015 (N = 136). We used mixed effects Poisson regression models with random intercepts for counties and year fixed effects to account for national trends. Models also included county and state characteristics associated with violence. Homicide was stratified by firearm versus all other methods to test for specificity of the laws' effects. PTP laws were associated with a 14% reduction in firearm homicide in large, urban counties (IRR = 0.86, 95% CI 0.82-0.90). CBC-only, SYG, RTC, and VM laws were all associated with increases in firearm homicide. None of the laws were associated with differences in non-firearm homicide rates. These findings are consistent with prior research at the state level showing PTP laws are associated with decreased firearm homicide. Testing the effects of PTP laws specifically in large, urban counties strengthens available evidence by isolating the effects in the geographic locations in which firearm homicides concentrate.

A population-based study of homicide deaths in Ontario, Canada using linked death records.

Homicide - a lethal expression of violence - has garnered little attention from public health researchers and health policy makers, despite the fact that homicides are a cause of preventable and premature death. Identifying populations at risk and the upstream determinants of homicide are important for addressing inequalities that hinder population health. This population-based study investigates the public health significance of homicides in Ontario, Canada, over the period of 1999-2012. We quantified the relative burden of homicides by comparing the socioeconomic gradient in homicides with the leading causes of death, cardiovascular disease (CVD) and neoplasm, and estimated the potential years of life lost (PYLL) due to homicide. We linked vital statistics from the Office of the Registrar General Deaths register (ORG-D) with Census and administrative data for all Ontario residents. We extracted all homicide, neoplasm, and cardiovascular deaths from 1999 to 2012, using International Classification of Diseases codes. For socioeconomic status (SES), we used two dimensions of the Ontario Marginalization Index (ON-Marg): material deprivation and residential instability. Trends were summarized across deprivation indices using age-specific rates, rate ratios, and PYLL. Young males, 15-29 years old, were the main victims of homicide with a rate of 3.85 [IC 95%: 3.56; 4.13] per 100,000 population and experienced an upward trend over the study period. The socioeconomic neighbourhood gradient was substantial and higher than the gradient for both cardiovascular and neoplasms. Finally, the PYLL due to homicide were 63,512 and 24,066 years for males and females, respectively. Homicides are an important cause of death among young males, and populations living in disadvantaged neighbourhoods. Our findings raise concerns about the burden of homicides in the Canadian population and the importance of addressing social determinants to address these premature deaths.

Homicide in Greenland has not often been investigated. The latest published study documented a dramatic rise in the homicide rate from around 1/100,000 inhabitants to more than 23/100,000 inhabitants from 1946 to 1984. The aim of our study was to characterize homicides in Greenland from 1985 to 2010 and to compare trends during this period with those in previous studies and with homicide characteristics in Denmark, northern Europe, and other Arctic regions. We identified a total of 281 homicides by legal definition and 194 by medical definition, the latter from the years 1990 to 2010. We procured case files for a total of 129 victims (71 male, 58 female) and 117 perpetrators (85 male, 32 female). We identified an overall decrease in the homicide rate during our study period. The decrease in the medical homicide rate was significant (p = 0.007). The homicide rate ranged from 25/100,000 inhabitants to 13/100,000 inhabitants when results were grouped within 5-year periods. There were significantly more male perpetrators (p < 0.001) and among female perpetrators there were significantly more male victims (p < 0.001). Sharp force and gunshot-related killings dominated homicide methods (41 and 29% respectively), with sharp force deaths increasing throughout the investigation period. Altercations were the main motive (49%). Alcohol-related homicides decreased in our study period. While the Greenlandic homicide rate has decreased, it is markedly higher compared to that seen in Denmark and northern Europe. However, it resembles the rate seen in the rest of the Arctic. Liberal gun laws do not affect the proportion of gun-related killings. Despite the high homicide rate, women account for almost half the victims.

Objectives To establish changes over time in the frequency of homicides committed by strangers, and to describe the personal and clinical characteristics of perpetrators of stranger homicides. Design Longitudinal study and national clinical survey. Participants People convicted of homicide in England and Wales between 1996 and 1999 and whether the victim was known to the perpetrator. Setting England and Wales. Main outcome measure Characteristics of perpetrators of homicides according to whether victims were strangers or not. Results Stranger homicides increased between 1967 and 1997, both in number and as a proportion of all homicides. No increase was found, however, in the number of perpetrators placed under a hospital order after homicide, whether all homicides or stranger homicides only. 358 of 1594 (22%) homicides were stranger homicides. In these cases the perpetrator was more likely to be male and young. The method of killing was more likely to be by hitting, kicking, or pushing (36% (130 of 358) for victims who were strangers to the perpetrator compared with 14% (145 of 1074) for victims who were known). Perpetrators were less likely to have a history of mental disorder (34%, n = 80 ν 50%, n = 142), a history of contact with mental health services (16%, 37 of 234 ν 24%, 200 of 824), and psychiatric symptoms at the time of the offence (6%, n = 14 ν 18%, n = 143). They were more likely to have a history of drug misuse (47%, n = 93 ν 37%, n = 272); alcohol (56%, n = 94 ν 41%, n = 285) or drugs (24% n = 44 ν 12%, n = 86) were more likely to have contributed to the offence. Conclusions Stranger homicides have increased, but the increase is not the result of homicides by mentally ill people and therefore the “care in the community” policy. Stranger homicides are more likely to be related to alcohol or drug misuse by young men. PMID:15044289

Introduction To better understand, and ultimately prevent, infant/child homicide, it is imperative to more thoroughly elucidate the circumstances and conditions related to such instances. Data were obtained from the US National Violent Death Reporting System (NVDRS) to illuminate circumstances related to homicide among children aged 4 years or less, and to identify demographic groups which may be at increased risk. Methods The NVDRS is an active surveillance system that provides comprehensive information on all violent deaths that occur within participating states within the US. Standard statistical tests were conducted to determine homicide rates among children ages 0–4 across states that provided data for both 2003 and 2004 (Alaska, Maryland, Massachusetts, New Jersey, Oregon, South Carolina, and Virginia). These data were further used to investigate infant/child homicides by race, gender, and other relevant circumstances (for example, victim‐suspect relationship, weapon type, and location of homicide). A Poisson regression model was fitted to the sample data to investigate the multivariate relationship between the infant/child homicide rate and available demographic information. Results The 2003 homicide rate for children ages 0–4 was 3.0 per 100 000 population. The 2004 homicide rate was 2.5 per 100 000 population. African Americans were 4.2 times as likely as whites to be victims of homicide. Suspects were commonly parents/caregivers. The vast majority of infant/child homicides occurred in houses or apartments, using weapons that include household objects. Conclusion Homicides of infants and young children are most often committed in the home, by parents/caregivers, using “weapons of opportunity”. This suggests that the risk of infant/child homicide is greatest within the primary care giving environment. Moreover, the use of “weapons of opportunity” may be indicative of maladaptive stress responses. Prevention and intervention strategies to reduce infant/child homicide should target the home environment and attend to maladaptive stress responses. PMID:17170170

Children who murder: a review.

Despite considerable research on juvenile homicide, pre-adolescent homicide offenders have received less attention. This paper reviews the existing literature on preteen murderers in order to characterize the current state of research knowledge about this population, and draws on some of the work on adolescent homicide as well. The analysis of this literature considers historical context, methodological issues, previous attempts to classify youthful homicide offenders, and predictors of preteen homicidal behavior. While there is a high degree of heterogeneity within this population, several developmental similarities emerged across cases that were associated with the perpetration of homicide by preteens. A high percentage of preteen homicide offenders come from homes characterized by physical abuse, domestic violence, poor or absent parenting, and overall instability. Gun availability may have been a facilitating factor. Support for different etiologies of preteen versus adolescent homicide is weak. Recommendations for future research directions are offered.

Homicide rate in Lithuania between 2004 and 2013 decreased and reached an average of 6.7 per 100,000 people in 2013. The data regarding forensic autopsies of intentional homicide victims were obtained from the State Forensic Medicine Service. Spearman's correlation test was used to assess trends in the homicide rates. A significant correlation was observed between homicide distribution and the following variables: Lithuania's gross domestic product (r = -0.85, p = 0.003), the number of alcohol intoxication cases of victims (r = 0.97, p < 0.05). After regression model adjustments, these variables remained significantly associated with the homicide distribution (p < 0.05). 73% of victims were men, with a mean age of 45.5 ± 15. Alcohol intoxication was present in 58% of victims. 66% of homicides were carried out indoors, 57% in urban area. The presented findings help decide which prevention programs may be the most effective in homicide rate reduction. © 2017 American Academy of Forensic Sciences.

Aggressiveness, violence, homicidality, homicide, and Lyme disease

Bransfield, Robert C

2018-01-01

Background No study has previously analyzed aggressiveness, homicide, and Lyme disease (LD). Materials and methods Retrospective LD chart reviews analyzed aggressiveness, compared 50 homicidal with 50 non-homicidal patients, and analyzed homicides. Results Most aggression with LD was impulsive, sometimes provoked by intrusive symptoms, sensory stimulation or frustration and was invariably bizarre and senseless. About 9.6% of LD patients were homicidal with the average diagnosis delay of 9 years. Postinfection findings associated with homicidality that separated from the non-homicidal group within the 95% confidence interval included suicidality, sudden abrupt mood swings, explosive anger, paranoia, anhedonia, hypervigilance, exaggerated startle, disinhibition, nightmares, depersonalization, intrusive aggressive images, dissociative episodes, derealization, intrusive sexual images, marital/family problems, legal problems, substance abuse, depression, panic disorder, memory impairments, neuropathy, cranial nerve symptoms, and decreased libido. Seven LD homicides included predatory aggression, poor impulse control, and psychosis. Some patients have selective hyperacusis to mouth sounds, which I propose may be the result of brain dysfunction causing a disinhibition of a primitive fear of oral predation. Conclusion LD and the immune, biochemical, neurotransmitter, and the neural circuit reactions to it can cause impairments associated with violence. Many LD patients have no aggressiveness tendencies or only mild degrees of low frustration tolerance and irritability and pose no danger; however, a lesser number experience explosive anger, a lesser number experience homicidal thoughts and impulses, and much lesser number commit homicides. Since such large numbers are affected by LD, this small percent can be highly significant. Much of the violence associated with LD can be avoided with better prevention, diagnosis, and treatment of LD. PMID:29576731

Work-related homicides among seafarers and fishermen.

Roberts, Stephen E

2004-01-01

To analyse work related homicides among various defined populations of seafarers and fishermen during the period 1976-2002, to compare homicide rates with other occupations and general populations, and to discuss implications for maritime health and safety. A longitudinal study of work related homicides, based on official mortality files, with an aggregated population of almost two million seafarer-and fishermen-years at risk. Of 46 work related homicides, 44 occurred among seafarers, and two among fishermen. Homicide rates were 1.5 per 100,000 worker-years among seafarers in British merchant shipping (1976-2002), 2.9 per 100,000 among British seafarers employed in non British shipping (1986-95), 3.7 in Singapore shipping (1984-95) and in Hong Kong shipping (1981-95), and 0.4 among fishermen in British fishing (1976-2002). The homicide rate in British shipping increased from 2.7 per 100,000 seafarer-years in 1961-65 to 4.4 per 100,000 in 1971-75, but has declined to 0.0 in 1996-2002. Although work related homicides were generally quite rare occurrences, among British seafarers and fishermen, they were largely caused by attacks from assailants, other than colleagues, that occurred ashore. The decline in the homicide rate in British shipping since the 1970s has coincided with the reduction in deep-sea ships trading to high risk countries for homicide. Among Asian seafarers, most homicides resulted from disputes among colleagues that mainly occurred on board ships. Prevention should include alertness to potential risks when spending off-duty time ashore in locations with high homicide rates, and conflict resolution for disputes among seafarers.

Characteristics of homicide followed by suicide incidents in multiple states, 2003-04.

2006-12-01

To calculate the prevalence of homicide followed by suicide (homicide/suicide) and provide contextual information on the incidents and demographic information about the individuals involved using data from a surveillance system that is uniquely equipped to study homicide/suicide. Data are from the National Violent Death Reporting System (NVDRS). This active state-based surveillance system includes data from seven states for 2003 and 13 states for 2004. The incident-level structure facilitates identification of homicide/suicide incidents. Within participating states, 65 homicide/suicide incidents (homicide rate = 0.230/100,000) occurred in 2003 and 144 incidents (homicide rate = 0.238/100,000) occurred in 2004. Most victims (58%) were a current or former intimate partner of the perpetrator. Among all male perpetrators of intimate partner homicide 30.6% were also suicides. A substantial proportion of the victims (13.7%) were the children of the perpetrator. Overall, most victims (74.6%) were female and most perpetrators were male (91.9%). A recent history of legal problems (25.3%), or financial problems (9.3%) was common among the perpetrators. The results support earlier research documenting the importance of intimate partner violence (IPV) and situational stressors on homicide/suicide. These results suggest that efforts to provide assistance to families in crisis and enhance the safety of IPV victims are needed to reduce risk for homicide/suicide. The consistency of the results from the NVDRS with those from past studies and the comprehensive information available in the NVDRS highlight the promise of this system for studying homicide/suicide incidents and for evaluating the impact of prevention policies and programs.

Community violence, including assault and homicide, is a public health problem. We provide a profile of assault-related injury and homicide death in Rhode Island to better understand assault/homicide. The 2014 emergency department (ED) visit data, hospital discharge (HD) data, and 2004-2014 Rhode Island Violent Death Reporting System (RIVDRS) data were used for this study. Most assault injuries and homicide deaths were among persons who were 25-44 years old, male, black and Hispanic, living in urban regions, self-pay or public insurance user, and never married. Almost 63% of the homicide decedents tested positive for some illicit substance. Precipitating circumstances include a preceding argument or a conflict, another crime, intimate partner violence, and drug involvement. RIVDRS did not provide an estimate for mental illness related homicides (e.g. command hallucinations). ED, HD, and RIVDRS data can provide a profile of assault injury and homicide death for public health authorities in RI. Interventions need to focus on high-risk populations and areas to effectively prevent assault-related injury and homicide. [Full article available at http://rimed.org/rimedicaljournal-2017-04.asp].

Association Between Connecticut’s Permit-to-Purchase Handgun Law and Homicides

Rudolph, Kara E.; Stuart, Elizabeth A.; Vernick, Jon S.

2015-01-01

Objectives. We sought to estimate the effect of Connecticut’s implementation of a handgun permit-to-purchase law in October 1995 on subsequent homicides. Methods. Using the synthetic control method, we compared Connecticut’s homicide rates after the law’s implementation to rates we would have expected had the law not been implemented. To estimate the counterfactual, we used longitudinal data from a weighted combination of comparison states identified based on the ability of their prelaw homicide trends and covariates to predict prelaw homicide trends in Connecticut. Results. We estimated that the law was associated with a 40% reduction in Connecticut’s firearm homicide rates during the first 10 years that the law was in place. By contrast, there was no evidence for a reduction in nonfirearm homicides. Conclusions. Consistent with prior research, this study demonstrated that Connecticut’s handgun permit-to-purchase law was associated with a subsequent reduction in homicide rates. As would be expected if the law drove the reduction, the policy’s effects were only evident for homicides committed with firearms. PMID:26066959

Family carers of people with dementia have higher than average rates of suicidal ideation, but there has been no research on homicidal ideation in this population. The aim of this study was to explore thoughts of homicide in family carers of people with dementia. A descriptive qualitative approach was taken. Twenty-one Australian carers (7 men, 14 women) participated in individual, in-depth interviews and the transcripts were analysed thematically. Seven themes were identified in the data - active thoughts of homicide; understanding homicidal thoughts in others; passive thoughts of death; euthanasia; homicidal thoughts in other caregiving situations; abuse; and disclosing thoughts of harm. Two of the 21 participants had actively contemplated the homicide of their care recipient, four expressed a passive desire for the care recipient's death, and four reported physically or verbally abusing the care recipient. Only one carer had previously disclosed these experiences. Homicidal ideation is a real and significant phenomenon among family carers of people with dementia. Service providers and health professionals are encouraged to identify and support carers contemplating homicide, but to do so in a way that recognises the broader social context of carer burden.

Homicide-suicide in the United States, 1968-1975.

PubMed

Bridges, F Stephen; Lester, David

2011-03-20

This paper describes for the first time the epidemiology of homicide-suicide events in the whole of the United States using archival data. From 1968 to 1975, there were 2215 homicide-suicide events out of 123,467 homicides. The mean rate of homicide-suicide events was 0.134 per 100,000 per year. The murderers in these events differ from the typical murderer and the typical suicide in socio-demographic characteristics. Details of the characteristics of this population may be valuable for understanding the circumstances of homicide-suicide events and planning preventive measures.

Chu, L D; Sorenson, S B

1996-01-01

In addition to the need to identify homicide trends among well-documented risk groups, this investigation was conducted to expand the limited existing knowledge about the risk of homicide according to educational attainment and among 2 growing ethnic groups, Hispanics and Asians. We examined the death certificates of the 69,621 persons who died of homicide in California from 1970 through 1993. Age, sex, race and ethnicity, and education level of the victim, along with the homicide method, were abstracted from each record. Frequencies, rates, and relative risk were calculated. Substantial increases in the homicide rates occurred for 15- to 19-year-olds (4.0-fold), men (1.9-fold), Hispanics (2.5-fold), and Asians or others (1.7-fold) from 1970 to 1993. The use of firearms consistently accounted for a growing proportion of all homicides, reaching a high in 1993 of 75% for all persons and 90% for 15- to 19-year-olds. High school dropouts have the highest homicide risk of all education groups. Homicide risk differentials by ethnicity, sex, and age all increased during the study period. Persons of color and youth have been disproportionately affected by homicide for many years, and these data indicate that things are getting worse. Redoubled collaborative prevention and intervention efforts are needed to reverse this trend. PMID:8909163

Firearm and Nonfirearm Homicide in 5 South African Cities: A Retrospective Population-Based Study

Thompson, Mary Lou; Myers, Jonathan E.

2014-01-01

Objective. We assessed the effectiveness of South Africa’s Firearm Control Act (FCA), passed in 2000, on firearm homicide rates compared with rates of nonfirearm homicide across 5 South African cities from 2001 to 2005. Methods. We conducted a retrospective population-based study of 37 067 firearm and nonfirearm homicide cases. Generalized linear models helped estimate and compare time trends of firearm and nonfirearm homicides, adjusting for age, sex, race, day of week, city, year of death, and population size. Results. There was a statistically significant decreasing trend regarding firearm homicides from 2001, with an adjusted year-on-year homicide rate ratio of 0.864 (95% confidence interval [CI] = 0.848, 0.880), representing a decrease of 13.6% per annum. The year-on-year decrease in nonfirearm homicide rates was also significant, but considerably lower at 0.976 (95% CI = 0.954, 0.997). Results suggest that 4585 (95% CI = 4427, 4723) lives were saved across 5 cities from 2001 to 2005 because of the FCA. Conclusions. Strength, timing and consistent decline suggest stricter gun control mediated by the FCA accounted for a significant decrease in homicide overall, and firearm homicide in particular, during the study period.

Infant homicide and accidental death in the United States, 1940-2005: ethics and epidemiological classification.

PubMed

Riggs, Jack E; Hobbs, Gerald R

2011-07-01

Potential ethical issues can arise during the process of epidemiological classification. For example, unnatural infant deaths are classified as accidental deaths or homicides. Societal sensitivity to the physical abuse and neglect of children has increased over recent decades. This enhanced sensitivity could impact reported infant homicide rates. Infant homicide and accident mortality rates in boys and girls in the USA from 1940 to 2005 were analysed. In 1940, infant accident mortality rates were over 20 times greater than infant homicide rates in both boys and girls. After about 1980, when the ratio of infant accident mortality rates to infant homicide rates decreased to less than five, and the sum of infant accident and homicide rates became relatively constant, further decreases in infant accident mortality rates were associated with increases in reported infant homicide rates. These findings suggest that the dramatic decline of accidental infant mortality and recent increased societal sensitivity to child abuse may be related to the increased infant homicide rates observed in the USA since 1980 rather than an actual increase in societal violence directed against infants. Ethical consequences of epidemiological classification, involving the principles of beneficence, non-maleficence and justice, are suggested by observed patterns in infant accidental deaths and homicides in the USA from 1940 to 2005.

The effect of urban street gang densities on small area homicide incidence in a large metropolitan county, 1994-2002.

The presence of street gangs has been hypothesized as influencing overall levels of violence in urban communities through a process of gun-drug diffusion and cross-type homicide. This effect is said to act independently of other known correlates of violence, i.e., neighborhood poverty. To test this hypothesis, we independently assessed the impact of population exposure to local street gang densities on 8-year homicide rates in small areas of Los Angeles County, California. Homicide data from the Los Angeles County Coroners Office were analyzed with original field survey data on street gang locations, while controlling for the established covariates of community homicide rates. Bivariate and multivariate regression analyses explicated strong relationships between homicide rates, gang density, race/ethnicity, and socioeconomic structure. Street gang densities alone had cumulative effects on small area homicide rates. Local gang densities, along with high school dropout rates, high unemployment rates, racial and ethnic concentration, and higher population densities, together explained 90% of the variation in local 8-year homicide rates. Several other commonly considered covariates were insignificant in the model. Urban environments with higher densities of street gangs exhibited higher overall homicide rates, independent of other community covariates of homicide. The unique nature of street gang killings and their greater potential to influence future local rates of violence suggests that more direct public health interventions are needed alongside traditional criminal justice mechanisms to combat urban violence and homicides.

The dynamic relationship between homicide rates and social, economic, and political factors from 1970 to 2000*.

After reaching their highest levels of the 20th century, homicide rates in the United States declined precipitously in the early 1990s. This study examines a number of factors that might have contributed to both the sharp increase and decline in homicide rates. We use a pooled cross-sectional time series model to assess the relationship between changes in structural conditions and the change in homicide rates over four decennial time points (1970, 1980, 1990, and 2000). We assess the extent to which structural covariates associated with social, economic and political conditions commonly used in homicide research (e.g., urban decay, poverty, and the weakening of family and social bonds) are related to the change in homicide rates. Along with these classic covariates, we incorporate some contemporary explanations (e.g., imprisonment rates and drug trafficking) that have been proposed to address the recent decline in urban homicide rates. Our results indicate that both classic and contemporary explanations are related to homicide trends over the last three decades of the 20th century. Specifically, changes in resource deprivation and in the relative size of the youth population are associated with changes in the homicide rate across these time points. Increased imprisonment is also significantly related to homicide changes. These findings lead us to conclude that efforts to understand the changing nature of homicide will require serious consideration, if not integration, of classic and contemporary explanations.

Canadian firearms legislation and effects on homicide 1974 to 2008.

2012-08-01

Canada has implemented legislation covering all firearms since 1977 and presents a model to examine incremental firearms control. The effect of legislation on homicide by firearm and the subcategory, spousal homicide, is controversial and has not been well studied to date. Legislative effects on homicide and spousal homicide were analyzed using data obtained from Statistics Canada from 1974 to 2008. Three statistical methods were applied to search for any associated effects of firearms legislation. Interrupted time series regression, ARIMA, and Joinpoint analysis were performed. Neither were any significant beneficial associations between firearms legislation and homicide or spousal homicide rates found after the passage of three Acts by the Canadian Parliament--Bill C-51 (1977), C-17 (1991), and C-68 (1995)--nor were effects found after the implementation of licensing in 2001 and the registration of rifles and shotguns in 2003. After the passage of C-68, a decrease in the rate of the decline of homicide by firearm was found by interrupted regression. Joinpoint analysis also found an increasing trend in homicide by firearm rate post the enactment of the licensing portion of C-68. Other factors found to be associated with homicide rates were median age, unemployment, immigration rates, percentage of population in low-income bracket, Gini index of income equality, population per police officer, and incarceration rate. This study failed to demonstrate a beneficial association between legislation and firearm homicide rates between 1974 and 2008.

Homicide in post-Soviet Belarus: urban-rural trends.

2009-01-01

To investigate the occurrence of homicide in urban and rural regions of Belarus in the post-Soviet period. All-age male and female homicide mortality and population data were obtained for the years 1990, 1995, 2000 and 2005 for urban and rural regions of Belarus. These data were recalculated into three age categories and directly standardised. To assess relative changes in rural-urban homicide rates across time Poisson regression models were used to calculate rate ratios. Between 1990 and 1995 homicide rates rose sharply in urban and rural regions although the rise was greater in the former. Although there was little change in homicide rates in 2000, a notable divergence had occurred by 2005. While homicide rates rose slightly in rural areas, a large fall occurred in the rates of both men and women in urban areas. This resulted in significantly higher rural homicide rate ratios at the end of the study period. With some variations age-specific homicide rates followed this overall general pattern resulting in significantly higher homicide rate ratios in all rural groups aged 15 and above in 2005. It is probable that a combination of factors such as high levels of poverty, the effects of alcohol consumption, as well as the poor provision of emergency medical services underlie both the high levels of lethal violence and the growing rural-urban divergence in homicide rates in contemporary Belarus. Urgent action is now needed to address the deteriorating social and economic conditions underpinning violence, especially in rural regions.

2012-12-01

The aim of our study was to analyze the homicide pattern in the Western suburbs of Paris and its evolution between 1994 and 2008. All autopsy reports regarding homicides from the period January 1, 1994, to December 31, 2008, were retrospectively reviewed. Five hundred eleven homicide cases were selected of 4842 autopsy cases. The following data were recorded: assailants and victims characteristics, crime scene location, homicide motive, cause of death, and victim's postmortem toxicological results. Homicide rate steadily declined over the period at the exception of the number of homicide-suicide per year, which remained constant. Homicide victims remained unidentified after medicolegal investigations in 2% of the cases. Child and elder homicide cases represented, respectively, 10.7% and 8.2% of the cases. Offenders were male in 88% of the cases. Male and female assailants showed distinct homicide patterns: females were involved more frequently in familial quarrel and child abuse. They never killed a stranger and committed homicide exclusively in a private place with a predominance of sharp weapons. Males, in contrast, assaulted almost equally a stranger or an acquaintance, often in a public place with a predominance of firearm. Victim knew the assailant(s) in 57% of the cases. Homicides mostly took place at the residence of the assailant or the victim. Homicide motive was clearly determined in 71% of the cases. Argument was the most common motive in 44% of the cases. Sexual assault was rarely found (10 cases). Gunshot wounds were the most common cause of death (37%), followed by stab wounds (27%), blunt trauma (19%), and asphyxia (13%). A decrease of gunshot wounds as a cause of death was found over the studied period. Alcohol was the most common toxic detected in blood of the victim, in 48.5% of the cases when toxicological results were available. Blood alcohol concentration ranged from 1 to 500 mg/dL with a mean value of 150 mg/dL.

Objectives. We examined the relationship between gun ownership and stranger versus nonstranger homicide rates. Methods. Using data from the Supplemental Homicide Reports of the Federal Bureau of Investigation’s Uniform Crime Reports for all 50 states for 1981 to 2010, we modeled stranger and nonstranger homicide rates as a function of state-level gun ownership, measured by a proxy, controlling for potential confounders. We used a negative binomial regression model with fixed effects for year, accounting for clustering of observations among states by using generalized estimating equations. Results. We found no robust, statistically significant correlation between gun ownership and stranger firearm homicide rates. However, we found a positive and significant association between gun ownership and nonstranger firearm homicide rates. The incidence rate ratio for nonstranger firearm homicide rate associated with gun ownership was 1.014 (95% confidence interval = 1.009, 1.019). Conclusions. Our findings challenge the argument that gun ownership deters violent crime, in particular, homicides. PMID:25121817

2014-04-01

In the USA, homicide is a leading cause of death for young males and a major cause of racial disparities in life expectancy for men. There are intense debate and little rigorous research on the effects of firearm sales regulation on homicides. This study estimates the impact of Missouri's 2007 repeal of its permit-to-purchase (PTP) handgun law on states' homicide rates and controls for changes in poverty, unemployment, crime, incarceration, policing levels, and other policies that could potentially affect homicides. Using death certificate data available through 2010, the repeal of Missouri's PTP law was associated with an increase in annual firearm homicides rates of 1.09 per 100,000 (+23%) but was unrelated to changes in non-firearm homicide rates. Using Uniform Crime Reporting data from police through 2012, the law's repeal was associated with increased annual murders rates of 0.93 per 100,000 (+16%). These estimated effects translate to increases of between 55 and 63 homicides per year in Missouri.

A comparative analysis of firearm homicides committed in Belgrade was performed including four representative years: 1987 (before the civil war in the Former Yugoslavia), 1991 (beginning of the war), 1997 (end of the war), and 2007 (period of social stabilization). The increase in the number of homicides was established in 1991 and 1997 compared with 1987, with the decrease in 2007, but with the continuous increase in the percentage of firearm homicides in the total number of homicides, from 12% in 1987 up to 56% in 2007. The significant increase in firearm homicides during the last decade of the 20th century can be explained by the social disturbances and the high availability of firearms, while their reduction in 2007 could be linked to the gradual stabilization of social circumstances. The results showed that the actual social, political, and economical changes strongly influenced medicolegal characteristics of homicides and particularly firearm homicides. © 2013 American Academy of Forensic Sciences.

Kitchen knives and homicide: a systematic study of people charged with murder in the Lothian and Borders region of Scotland.

Kidd, S H; Hughes, N S; Crichton, J H M

2014-07-01

A recent English study demonstrated high rates of kitchen knife use in homicides by mentally disordered offenders subject to independent inquiries. Everyone accused of homicide in Scotland undergoes psychiatric examination; all such evaluations in a Scottish region between 2006 and 2011 were systematically analysed to identify homicide characteristics. It was hypothesised that kitchen knives would be the commonest sharp instruments used, and would be associated with unplanned domestic homicide against known victims, with no independent association with mental disorder. Kitchen knives were used in 32 of 55 homicides: 94% of 34 sharp object homicides (p < 0.05). No independent association was found between kitchen knife use and planning, location, relationship, intoxication or mental disorder. Kitchen knife use in homicide appears to be a significant public health issue, and not only in the mentally disordered population. Research is recommended into kitchen knife use in non-fatal violence, and weapon control in populations at increased risk of knife violence.

To characterize the relationship between alcohol use and homicide victimization, we used data from the Los Angeles City Police Department and the Los Angeles Medical Examiner's Office to study 4,950 victims of criminal homicides in Los Angeles in the period 1970-79. Alcohol was detected in the blood of 1,883 (46 per cent) of the 4,092 victims who were tested. In 30 per cent of those tested, the blood alcohol level was greater than or equal to 100 mg/100 ml, the level of legal intoxication in most states. Blood alcohol was present most commonly in victims who were male, young, and Latino, categories where rates have been increasing at an alarming pace. Alcohol was also detected most commonly in victims killed during weekends, when homicides occurred in bars or restaurants, when homicides resulted from physical fights or verbal arguments, when victims were friends or acquaintances of offenders, and when homicides resulted from stabbings. The evidence for alcohol use by homicide victims focuses attention on the need for controlled epidemiologic studies of the role played by alcohol as a risk factor in homicide and on the importance of considering situational variables in developing approaches to homicide prevention.

The homicide statistics of a popular UK television fictional crime series and the former Lothian & Borders police force region, Scotland were compared. This comparison was used to consider the implications for public attitudes which may influence the adoption of public health interventions to reduce homicide. 217 homicides were identified by 105 perpetrators in the television series 'Midsomer Murders' between 1997 and 2011; these were compared to 55 homicides by 53 perpetrators in the regional sample between 2006 and 2011. The numbers of serial killings (p < 0.0001), planned homicides, female perpetrators (p < 0.0001), shootings (p = 0.0456) and poisonings (p = 0.0289) were higher in the fictional sample. Lothian & Borders cases were almost all single killings, mostly unplanned, with a far greater rate of homicide by kitchen knives (p < 0.0001) and hitting/kicking (p = 0.0005) by intoxicated perpetrators. Control of access to pointed kitchen knives by members of certain groups may reduce homicide rates. If the popular perception of UK homicides is influenced by popular culture, the importance of such a public health intervention may not be apparent.

Sorenson, S B; Peterson, J G

1994-01-01

OBJECTIVES. Child abuse is a presumed but largely untested risk factor for child homicide. This research investigated the social and child protective service history of child homicide victims. METHODS. A pairwise matched case-control design was used to assess documented child maltreatment as a risk factor for homicide vs unintentional injury death. Homicide victims aged 0 to 14 years were identified through Los Angeles Police Department case summaries. Control subjects (children who died of an unintentional injury) were matched to case subjects (children who died from homicide) by age, sex, race/ethnicity, and date of death. Case and control subjects were linked with county service records to determine any known history of maltreatment. RESULTS. A total of 220 children were homicide victims during 1978 through 1987 in the city of Los Angeles. Only one in six children who died (of homicide or unintentional injury) or his/her family was known to county social or child protective services prior to the death. Recorded history of child protective services was associated with homicide victimization (adjusted odds ratio = 3.40, 95% confidence interval = 1.25, 9.27). CONCLUSIONS. Current service systems need assistance in identifying and protecting children at high risk of homicide. PMID:8154567

To assess female homicide rates due to aggression according to sociodemographic and health indicators. Ecological study on female homicides due to aggression in Brazil between 2003 and 2007. Information on 19,459 deaths were obtained form the Brazilian Mortality Database. Standardized female homicide rates due to aggression were correlated with 28 socioeconomic, demographic and health indicators, using Pearson's correlation test. Multiple linear regression was performed including variables with p < 0.20 and excluding those with multicollinearity. The standardized female homicide rate due to aggression was 4.1/100,000 during the study period. After adjustment, three variables remained significantly associated with female homicides: birth rate (p = 0.072), percentage of Evangelicals (p = 0.019) and male homicides due to aggression (p < 0.001). The model had a predictive power of 69% (r² = 0.699). The Brazilian states of Espírito Santo, Pernambuco, Mato Grosso, Rio de Janeiro, Rondônia, Alagoas, Mato Grosso do Sul, Roraima e Amapá showed the highest rates during the study period. The female homicide rates due to aggression were high in Brazil and varied by region. The association with male homicides due to aggression stresses the importance of reducing structural violence to protect women against violence.

Drug and alcohol use by homicide victims in Trinidad and Tobago, 2001-2007.

Kuhns, Joseph B; Maguire, Edward R

2012-09-01

This paper examines toxicology results from homicide victims in Trinidad and Tobago to explore patterns in pre-mortem drug and alcohol use. Toxicology test results were obtained for 1,780 homicide victims. Toxicology data from the coroner's office were linked with police data on homicide incidents to examine patterns in drug use and homicide. Trinidad and Tobago homicide victims tested positive for cannabis at a significantly higher rate (32%) than the average rate among other drug toxicology studies. Victims tested positive for alcohol (29%), cocaine (7%), and opioids (1.5%) at rates that were either comparable with or lower than those of homicide victims examined in other studies. The proportion of victims testing positive for cannabis grew significantly from 2001 to 2007; the proportions for alcohol and other drugs were fairly stable over time. Toxicology results also varied by homicide motive, weapon type, and the demographic characteristics of the victim. Toxicology data are a useful source for understanding patterns in drug use and homicide. Though such data have limitations, when combined with other types of data, they can often provide unique insights about a community's drug and violence problems.

Preventing homicide: an evaluation of the efficacy of a Detroit gun ordinance.

BACKGROUND: In November 1986, a Detroit, Michigan city ordinance requiring mandatory jail sentences for illegally carrying a firearm in public was passed to preserve "the public peace, health, safety, and welfare of the people." METHODS: We conducted a set of interrupted time-series analyses to evaluate the impact of the law on the incidence of homicides, hypothesizing that the ordinance, by its nature, would affect only firearm homicides and homicides committed outside (e.g., on the street). RESULTS: The incidence of homicide in general increased after the law was passed, but the increases in non-firearm homicides and homicides committed inside (e.g., in a home) were either statistically significant or approached statistical significance (p = .006 and p = .070, respectively), whereas changes in the incidence of firearm homicides and homicides committed outside were not statistically significant (p = .238 and p = .418, respectively). We also determined that the ordinance was essentially unenforced, apparently because of a critical shortage of jail space. CONCLUSIONS: Our findings are consistent with a model in which the ordinance had a dampening effect on firearm homicides occurring in public in Detroit. The apparent preventive effect evident in the time series analyses may have been due to publicity about the ordinance, whereas the small nature of the effect may have been due to the lack of enforcement.

Women who kill their mates.

Bourget, Dominique; Gagné, Pierre

2012-01-01

Spousal homicide perpetrators are much more likely to be men than women. Accordingly, little research has focused on delineating characteristics of women who have committed spousal homicide. A retrospective clinical review of coroners' files containing all cases of spousal homicide occurring in Quebec over a 20-year period was carried out. A total of 276 spousal homicides occurred between 1991 and 2010, with 42 homicides by female spouses and 234 homicides by male spouses. Differences between homicides committed by female offenders and male offenders are discussed, and findings on spousal homicide committed by women are compared with those of previous studies. Findings regarding offenses perpetrated by females in the context of mental illness, domestic violence, and homicide-suicide are explored. The finding that only 28% of the female offenders in the Quebec sample had previously been subjected to violence by their victim is in contrast to the popular belief and reports that indicate that most female-perpetrated spousal homicide occurs in self-defense or in reaction to long-term abuse. In fact, women rarely gave a warning before killing their mates. Most did not suffer from a mental illness, although one-fifth were acutely intoxicated at the time of the killing. In the vast majority of cases of women who killed their mates, there were very few indicators that might have signaled the risk and helped predict the violent lethal behavior.

Homicide-suicide in Ghana: perpetrators, victims, and incidence characteristics.

PubMed

Adinkrah, Mensah

2014-03-01

Homicide-suicide in the industrialized West has been studied for many years. Yet, only limited scholarly research currently exists on the subject in Africa and other non-Western societies. The aim of the present descriptive study was to investigate homicide-suicides in contemporary Ghana. A content analysis of homicide-suicide reports in a major Ghanaian daily newspaper during 1990 to 2009 was conducted. The results overwhelmingly support findings in the literature, suggesting that homicide-suicides are extremely rare events in Ghana. The overwhelming majority of reported homicide-suicides were committed by males, with females substantially more likely to be the homicide victims. The offenders and victims were generally of low socioeconomic status. Most homicide-suicides involved victims and offenders who were intimately acquainted as family members. The majority of cases involved men who killed their wives on suspicion of infidelity; the next largest category involved men who murdered wives who threatened divorce or separation. The principal homicide and suicide methods were shooting with firearms, hacking with machetes, and stabbing with knives. The findings of the study are discussed in relation to Ghana's patriarchal family system and ideology and present socioeconomic issues in the country. This study recommends further research on this subject in Ghana and other African countries. This is necessary to further an understanding of homicide-suicide as a phenomenon, as well as a necessary prelude to the development and implementation of effective preventive programs.

Vodka and Violence: Alcohol Consumption and Homicide Rates in Russia

Pridemore, William Alex

2002-01-01

In Russia, rates of alcohol consumption and homicide are among the highest in the world, and already-high levels increased dramatically after the breakup of the Soviet Union. Rates of both, however, vary greatly among Russia’s 89 regions. We took advantage of newly available vital statistics and socioeconomic data to examine the regional covariation of drinking and lethal violence. Log-log models were employed to estimate the impact of alcohol consumption on regional homicide rates, controlling for structural factors thought to influence the spatial distribution of homicide rates. Results revealed a positive and significant relationship between alcohol consumption and homicide, with a 1% increase in regional consumption of alcohol associated with an approximately 0.25% increase in homicide rates. In Russia, higher regional rates of alcohol consumption are associated with higher rates of homicide. PMID:12453810

Annually, over a thousand children are the victims of homicide in the United States Homicide among younger children, 0-9 years of age, is usually perpetrated by parents and caregivers. Researchers neither have tracked changes in the homicide rate among young children over time nor have they used theory to understand what factors may drive these changes. In this analysis of state-level data, we used longitudinal growth modeling and ecological theory to examine changes in homicide rate against children aged 0-9 years from 1979 to 2007. Our results indicate that states are relatively consistent, over time, in their homicide rates. Furthermore, a cultural context of criminal and risky behavior is positively associated with homicide against children. We discuss implications for future research and prevention.

Intimate-partner homicide among pregnant and postpartum women.

Cheng, Diana; Horon, Isabelle L

2010-06-01

To identify pregnancy-associated homicide cases and to estimate the proportion that were perpetrated by a current or former intimate partner. This was an analysis of pregnancy-associated homicides occurring from 1993 to 2008 among Maryland residents using linked birth and death certificates, medical examiner charts, police records, and news publications. Homicides (n=110) were the leading cause of death during pregnancy and the first postpartum year. Women who were African American, younger than 25 years, and unmarried were at the highest risk for homicide. Firearms were the most common (61.8%) method of death. A current or former intimate partner was the perpetrator in 54.5% (n=60) of homicide deaths and a nonpartner in 31.8% (n=35). If the cases (n=15) in which the victim-offender relationship could not be identified are excluded, 63.2% of homicides were committed by an intimate partner. Compared with homicides in which the perpetrator was not an intimate partner, a significantly higher percentage (P<.05) of intimate-partner homicides occurred at home (66.7% compared with 28.6%), among women who had completed more than 12 years of education (23.3% compared with 5.7%), and who were married (28.3% compared with 8.6%). Intimate-partner homicides were most prevalent (25.0%) during the first 3 months of pregnancy and least prevalent during the first 3 months postpartum (5.0%). The majority of pregnancy-associated homicides were committed by current or former intimate partners, most commonly during the first 3 months of pregnancy. Efforts to protect women from partners optimally should begin before conception or very early in pregnancy. III.

The purpose of this study was to examine the associations between the alcohol policy environment and alcohol involvement in homicide victims in the United States, overall and by sociodemographic groups. To characterize the alcohol policy environment, the presence, efficacy, and degree of implementation of 29 alcohol policies were used to determine Alcohol Policy Scale (APS) scores by state and year. Data about homicide victims from 17 states from 2003 to 2012 were obtained from the National Violent Death Reporting System. APS scores were used as lagged exposure variables in generalized estimating equation logistic regression models to predict the individual-level odds of alcohol involvement (i.e., blood alcohol concentration [BAC] > 0.00% vs. = 0.00% and BAC ≥ 0.08% vs. ≤ 0.079%) among homicide victims. A 10 percentage point increase in APS score (representing a more restrictive policy environment) was associated with reduced odds of alcohol-involved homicide with BAC greater than 0.00% (adjusted odds ratio [AOR] = 0.89, 95% CI [0.82, 0.99]) and BAC of 0.08% or more (AOR = 0.91, 95% CI [0.82, 1.02]). In stratified analyses of homicide victims, more restrictive policy environments were significantly protective of alcohol involvement at both BAC levels among those who were female, ages 21-29 years, Hispanic, unmarried, victims of firearm homicides, and victims of homicides related to intimate partner violence. More restrictive alcohol policy environments were associated with reduced odds of alcohol-involved homicide victimization overall and among groups at high risk of homicide. Strengthening alcohol policies is a promising homicide prevention strategy.

Austrian firearm legislation and its effects on suicide and homicide mortality: A natural quasi-experiment amidst the global economic crisis.

2018-08-01

Restriction of access to suicide methods has been shown to effectively reduce suicide mortality rates. To examine how the global economic crisis of 2008 and the firearm legislation reform of 1997 affected suicide and homicide mortality rate within Austria. Official data for the years 1985-2016 for firearm certificates, suicide, homicide, unemployment rates and alcohol consumption were examined using auto regressive error and Poisson regression models. Firearm certificates, total suicide mortality rate, suicide and homicides by firearms, and the fraction of firearm suicides/homicides among all suicides/homicides decreased after the firearm legislation reform in 1997. However, significant trend changes can be observed after 2008. The availability of firearm certificates significantly increased and was accompanied by significant changes in trends of firearm suicide and homicide rates. Concurrently, the total suicide mortality rate in 2008, for the first time since 1985, stopped its decreasing trend. While the total homicide rate further decreased, the fraction of firearm homicides among all homicides significantly increased. The initially preventative effect of the firearm legislation reform in Austria in 1997 seems to have been counteracted by the global economic downturn of 2008. Increased firearm availability was associated with corresponding increases in both firearm suicide and firearm homicide mortality. Restrictive firearm legislation should be an imperative part of a country's suicide prevention programme. Although firearm legislation reform may have long-lasting effects, societal changes may facilitate compensatory firearm acquisitions and thus counteract preventive efforts, calling in turn again for adapted counter-measures.

This forms the basis for formulating antecedents that are shared between homicide offenders and homicide victims at a young age (ages 7–11) and antecedents that are not shared or are unique for each. Implications of the research are highlighted for early intervention and for interventions with high-risk offenders.

To determine whether recommended robbery prevention strategies also protect against workplace homicide committed by a perpetrator who has a relationship with either the workplace or an employee (prior-relationship homicide). A case-control study examining the relationship between recommended violence prevention strategies and prior-relationship workplace homicides in North Carolina was conducted. Workplaces located in an industrial park, employing minorities, reporting a history of violence, open night hours, or open 24 hours were more likely to experience prior-relationship homicide. Keeping entrances to the workplace locked when employees were present (OR = 0.36, 95% CI: 0.13, 0.99) and having at least one security device (OR = 0.28, 95% CI: 0.10, 0.74) decreased the odds of prior-relationship homicide. Select strategies recommended to prevent robberies and subsequent violence may also afford protection against prior-relationship homicide.

Many legal residents in the United States (US)-Mexico border region cross from the US into Mexico for medical treatment and pharmaceuticals. We analyzed whether recent increases in homicides in Mexico are associated with reduced healthcare access for US border residents. We used data on healthcare access, legal entries to the US from Mexico, and Mexican homicide rates (2002-2010). Poisson regression models estimated associations between homicide rates and total legal US entries. Multivariate difference-in-difference linear probability models evaluated associations between Mexican homicide rates and self-reported measures of healthcare access for US residents. Increased homicide rates were associated with decreased legal entries to the US from Mexico. Contrary to expectations, homicides did not have significant associations with healthcare access measures for legal residents in US border counties. Despite a decrease in border crossings, increased violence in Mexico did not appear to negatively affect healthcare access for US border residents.

2014-07-01

From January 1987 to December 2012, 19 homicide-suicide events were registered at the Brescia Institute of Forensic Medicine (Northern Italy), leading to 39 deaths (20 homicide victims and 19 suicide victims). The homicide victims were females in the total of the cases (100%), while perpetrators were exclusively males (100%). Only one event involved foreigners as both victim and perpetrator, all the other cases regarded Italian people. The average age was 37.3 years for the homicide victims and 41.57 years for the offenders. Perpetrators usually used a firearm both for murder (65%) and suicide (84%). In 66% of the cases the homicide-suicide events occurred at home; homicide victims were strictly bound to their perpetrators (husband, boyfriend or ex boyfriend, father) in all the events.

Homicide has remained the third leading cause of death among girls aged 10 to 19 for more than a decade. Recent research indicates that pregnant or postpartum teens are three times more likely to be victims of homicide compared to their nonpregnant counterparts. These findings portray a compelling picture that leads the authors to investigate the relationship between homicide and pregnancy among teens in Maryland. The purpose of this study is to compare women whose deaths had been evaluated by the medical examiner and who had evidence of pregnancy to women without evidence of pregnancy, with a particular focus on adolescents; 329 (17.7%) adults and 66 (32.7%) adolescents were victims of homicide. Adolescent homicide victims were 3.7 (1.2 to 11.8) times more likely to be pregnant compared to adult homicide victims. The rate of homicide was nearly double in all women who were pregnant. Further research is necessary to evaluate factors associated with these risks so that the future generation and society are protected.

Domestic Homicide: Neuropsychological Profiles of Murderers Who Kill Family Members and Intimate Partners.

PubMed

Hanlon, Robert E; Brook, Michael; Demery, Jason A; Cunningham, Mark D

2016-01-01

Domestic homicide is the most extreme form of domestic violence and one of the most common types of homicide. The objective was to examine differences between spontaneous domestic homicide and nondomestic homicide offenders regarding demographics, psychiatric history, crime characteristics, and neuropsychological status, utilizing neuropsychological test data from forensic examinations of 153 murderers. Using standard crime classification criteria, 33% committed spontaneous domestic homicides (SDH) and 61% committed nondomestic homicides (NDH). SDH offenders were more likely to manifest psychotic disorders, but less likely to be diagnosed with antisocial personality disorder or to have prior felony convictions. SDH offenders manifested significantly worse neuropsychological impairments than NDH offenders. The mean number of victims was lower for the SDH than the NDH group and only 14% of SDH offenders used a firearm, whereas 59% of NDH offenders used a firearm. These findings corroborate the notion that spontaneous domestic homicide may represent a discernible criminological phenotype. © 2015 The Authors Journal of Forensic Sciences published by Wiley Periodicals, Inc. on behalf of American Academy of Forensic Sciences.

Homicide Rates of Transgender Individuals in the United States: 2010-2014.

PubMed

Dinno, Alexis

2017-09-01

To estimate homicide rates of transgender US residents and relative risks (RRs) of homicide with respect to cisgender comparators intersected with age, gender, and race/ethnicity. I estimated homicide rates for transgender residents and transfeminine, Black, Latin@, and young (aged 15-34 years) subpopulations during the period 2010 to 2014 using Transgender Day of Remembrance and National Coalition of Anti-Violence Programs transgender homicide data. I used estimated transgender prevalences to estimate RRs using cisgender comparators. I performed a sensitivity analysis to situate all results within assumptions about underreporting of transgender homicides and assumptions about the prevalence of transgender residents. The overall homicide rate of transgender individuals was likely to be less than that of cisgender individuals, with 8 of 12 RR estimates below 1.0. However, the homicide rates of young transfeminine Black and Latina residents were almost certainly higher than were those of cisfeminine comparators, with all RR estimates above 1.0 for Blacks and all above 1.0 for Latinas. Antiviolence public health programs should identify young and Black or Latina transfeminine women as an especially vulnerable population.

Hidden Homicide Increases in the USA, 1999–2005

PubMed Central

Hu, Guoqing; Webster, Daniel

2008-01-01

Prior to 1999, dramatic fluctuations in homicide rates were driven by changes in the rates of firearm homicide among men aged 15–24. Since 2000, the overall homicide rate has appeared stable, masking any changes in population subgroups. We analyzed recent trends in homicide rates by weapon, age, race, gender, state, and urbanization to determine whether the risk of victimization increased substantially during 1999–2005 for demographic subgroups. The analysis of WISQARS™ data and Wonder data from Centers for Disease Control and Prevention revealed no trend in the homicide rate nationally between 1999 and 2005; this obscured large increases in firearm homicide rates among black men aged 25–44 and among white men aged 25–34. Between 1999 and 2005, for ages 25–44 combined, the increase for black men was 31% compared with 12% for white men. Significant increases among men aged 25–44 occurred in Alabama, California, Michigan, Minnesota, Nebraska, Nevada, New Jersey, Ohio, Pennsylvania, Texas, and Washington. The firearm homicide rate increased the most in large central metropolitan areas (+32%) and large fringe metropolitan areas (+30%) for men aged 25–44. We conclude that the recent, unrecognized increases in firearm homicide among men aged 25–44, especially black men, in large metropolitan areas merit the attention of policymakers. PMID:18509760

Objectives. We assessed whether New York City's gun-related homicide rates in the 1990s were associated with a range of social determinants of homicide rates. Methods. We used cross-sectional time-series data for 74 New York City police precincts from 1990 through 1999, and we estimated Bayesian hierarchical models with a spatial error term. Homicide rates were estimated separately for victims aged 15–24 years (youths), 25–34 years (young adults), and 35 years or older (adults). Results. Decreased cocaine consumption was associated with declining homicide rates in youths (posterior median [PM] = 0.25; 95% Bayesian confidence interval [BCI] = 0.07, 0.45) and adults (PM = 0.07; 95% BCI = 0.02, 0.12), and declining alcohol consumption was associated with fewer homicides in young adults (PM = 0.14; 95% BCI = 0.02, 0.25). Receipt of public assistance was associated with fewer homicides for young adults (PM = –104.20; 95% BCI = –182.0, –26.14) and adults (PM = –28.76; 95% BCI = –52.65, –5.01). Misdemeanor policing was associated with fewer homicides in adults (PM = –0.01; 95% BCI = –0.02, –0.001). Conclusions. Substance use prevention policies and expansion of the social safety net may be able to cause major reductions in homicide among age groups that drive city homicide trends. PMID:20395590

Research concerning suicide and homicide in North Carolina is needed so that medical providers and others who develop and implement preventive and therapeutic interventions related to violence have an empirical base from which to work. North Carolina Violent Death Reporting System data composed of death certificates, medical examiner reports, and law enforcement reports were analyzed to examine the prevalence of suicide and homicide in North Carolina during 2004-2007 and to describe the sociodemographic characteristics of suicide and homicide victims. Suicides and homicides accounted for 2.3% of all North Carolina deaths during 2004-2007. There were 12.0 suicides (95% confidence interval [CI], 11.7-12.4) and 7.2 homicides (95% CI, 6.9-7.4) per 100,000 North Carolina residents. Suicide rates were higher among men and boys, whites, non-Hispanics, and persons aged > or = 35 years. Homicide rates were higher among men and boys, American Indians, blacks, Hispanics, and persons aged < or = 24 years. Firearms were the most common method used to commit suicide and homicide, accounting for 59.5% of suicides and 67.0% of homicides. Every day in North Carolina, approximately 3 persons kill themselves and approximately 2 persons are killed by others. Suicide and homicide inflict a high level of preventable mortality in North Carolina. Learning more about these violent deaths will help to inform the development of effective violence-prevention interventions.

Changes in the timing of SIDS deaths in 1989 and 1999: indirect evidence of low homicide prevalence among reported cases.

An unknown proportion of cases diagnosed as sudden infant death syndrome (SIDS) are misdiagnosed, and in some cases are homicides. Because recent SIDS prevention measures were unlikely to reduce homicides, changes in the reported timing of SIDS cases provide an indirect measure of covert homicides in this group. This paper uses United States vital statistics microdata to explore these questions. The sample includes all reported infant deaths to singletons with birthweight > 500 g in the 1989 and 1999 US birth cohorts. Deaths attributed to SIDS (n = 7708), homicide (n = 597), or object inhalation and mechanical suffocation (n = 860) are specifically examined. If reported SIDS cases were a mixture of 'true' cases and misdiagnosed homicides, it is hypothesised that the age-at-death distribution of SIDS deaths would have changed to reflect greater prevalence of misdiagnosed homicide. We find that the age-at-death distribution of reported SIDS cases was virtually unchanged in the two cohorts, showing no increase during periods of infancy when relative homicide risk is most pronounced. One cannot reject the hypothesis that the timing was drawn from the same distribution (chi2(52)= 62.2, P = 0.157). Analogous results hold for infants born in circumstances associated with high homicide risk (chi2(50) = 61.5, P = 0.12). The stable age-at-death distribution of reported SIDS cases between 1989 and 1999 suggests that covert homicides are a small fraction of reported SIDS cases.

Homicide is the second leading cause of death in children aged 0 to 19 years. Tailoring violence prevention programs to high-risk individuals requires understanding victim-offender relationships. To elucidate differences in the relationships between homicide victims aged 0 to 19 years and their offenders. Cross-sectional study using the Uniform Crime Reports: Supplemental Homicide Reports, 1976-1999. The Supplemental Homicide Reports contain incident-level information about criminal homicides, including location and victim and offender characteristics. National coverage is approximately 92%; 70 258 victims were studied. Differences in the relationships of homicide victims and offenders based on sex, age, population of homicide location, and weapon. Odds ratios and 95% confidence intervals (CIs) are reported. Using strangers as the referent group, murdered girls were 3.6 (95% CI, 3.4-3.9) times more likely to have been killed by family members and 21.3 (95% CI, 18.5-24.4) times more likely to have been killed by intimate partners than murdered boys. Victims younger than 10 years were 33 (95% CI, 30.4-36.1) times more likely than victims older than 10 years to have been killed by a family member and 2.4 (95% CI, 2.2-2.6) times more likely to have been killed by someone else known to them. Stranger homicides occurred in areas with approximately 145 000 more residents (P<.01). Handguns were more likely to be used during homicides committed by strangers (P<.01). These associations remained after adjusting for potential confounders. Future violence prevention programs may have more effect when targeted to specific sex and age groups. Elucidation of the origins of sex differences, focus on evidence-based child abuse prevention efforts, and enforcement of current gun control laws may help reduce the number of homicides among children.

To examine whether being pregnant or postpartum was associated with excess risk for homicide among females in Illinois and to describe the association between pregnancy status and homicide by race, ethnicity, and age group. This is a retrospective, multicohort, ecologic study of females of reproductive age in Illinois between 2002 and 2011 using Illinois Department of Public Health maternal mortality data and vital records data. We compared pregnancy-associated homicides with live births using χ tests. Among maternal deaths in the state, we calculated mortality rates per 100,000 live births for homicide and other violent causes and the leading direct obstetric causes. We calculated aggregate, pregnancy-associated, and nonpregnancy associated homicide rates stratified by race or ethnicity and age group. There were 636 pregnancy-associated deaths in Illinois from 2002 to 2011. Of these, 82 (13%) were the result of homicide (5.0 [95% confidence interval (CI) 4.0-6.2]/100,000 live births). There were 931 homicides among females of reproductive age not associated with pregnancy (2.88 [95% CI 2.70-3.07]/100,000 population). More than half of the homicides were women aged 20-29 years (n=53 [64.6%]), non-Hispanic black women (n=43 [52.4%]), women residing in Cook County (n=47 [57.3%]), and unmarried women (n=57 [69.5%]). Pregnant and postpartum females aged 10-29 years were at twice the risk of homicide compared with their nonpregnant or postpartum counterparts (relative risk 2.20 [95% CI 1.70-2.85]). Non-Hispanic black and Hispanic females experienced higher rates of homicide than non-Hispanic white females irrespective of pregnancy or age. Although all violence against women must be addressed, we recommend that state maternal mortality review committees, in addition to reviewing deaths resulting from obstetric and clinical causes, should conduct in-depth reviews of pregnancy-associated homicides and other violent deaths.

Trends in rates of mental illness in homicide perpetrators.

The rise in homicides by those with serious mental illness is of concern, although this increase may not be continuing. To examine rates of mental illness among homicide perpetrators. A national consecutive case series of homicide perpetrators in England and Wales from 1997 to 2006. Rates of mental disorder were based on data from psychiatric reports, contact with psychiatric services, diminished responsibility verdict and hospital disposal. Of the 5884 homicides notified to the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness between 1997 and 2006, the number of homicide perpetrators with schizophrenia increased at a rate of 4% per year, those with psychotic symptoms at the time of the offence increased by 6% per year. The number of verdicts of diminished responsibility decreased but no change was found in the number of perpetrators receiving a hospital order disposal. The likeliest explanation for the rise in homicide by people with psychosis is the misuse of drugs and/or alcohol, which our data show increased at a similar magnitude to homicides by those with psychotic symptoms. However, we are unable to demonstrate a causal association. Although the Poisson regression provides evidence of an upward trend in homicide by people with serious mental illness between 1997 and 2006, the number of homicides fell in the final 2 years of data collection, so these findings should be treated with caution. There appears to be a concomitant increase in drug misuse over the period, which may account for this rise in homicide. However, an increase in the number of people in contact with mental health services may suggest that access to mental health services is improving. Previous studies have used court verdicts such as diminished responsibility as a proxy measure of mental disorder. Our data indicate that this does not reflect accurately the prevalence of mental disorder in this population.

Background The aim of the study was to evaluate psychopathy-like personality traits in a nationwide consecutive sample of adolescent male homicide offenders and to compare the findings with those of a randomly sampled adult male homicide offender group. A further aim was to investigate associations between psychopathic traits and offender and offence characteristics in adolescent homicides. Methods Forensic psychiatric examination reports and crime reports of all 15 to19- year- old male Finnish offenders who had been subjected to a forensic psychiatric examination and convicted for a homicide during 1995–2004 were collected (n = 57). A random sample of 57 adult male homicide offenders was selected as a comparison group. Offence and offender characteristics were collected from the files and a file-based assessment of psychopathic traits was performed using the Hare Psychopathy Checklist-Revised (PCL-R) by trained raters. Results No significant differences existed between the adolescents and adults in PCL-R total scores, factor 2 (social deviance) scores, or in facets 3 (lifestyle) and 4 (antisocial). Adults scored significantly higher on factor 1 (interpersonal/affective) and facets 1 (interpersonal) and 2 (affective). The adolescent group was divided into two subgroups according to PCL-R total scores. One in five homicidal male adolescents met criteria for psychopathic personality using a PCL-R total score of 26 or higher. These boys significantly more often had a crime history before the index homicide, more frequently used excessive violence during the index homicide, more rarely lived with both parents until 16 years of age, had more institutional or foster home placements in childhood, had more school difficulties, more often had received special education, and, more often had contact with mental health services prior to age 18 years than boys scoring low on the PCL-R. They also more often had parental criminal history as well as homicide history of parents or near relatives than the group scoring low on the PCL-R. Conclusion Homicidal boys behaved as antisocially as the homicidal adults. The adults, however, showed more both affective and interpersonal features of psychopathy. Homicidal adolescents with psychopathy-like personality character form a special subgroup among other homicidal youngsters. Recognizing their characteristics, especially in life course development, would facilitate effective prevention and intervention efforts. PMID:19419577

Homicide is the third leading cause of death for adolescents in the United States and the leading cause of death for adolescents who are African American. Large cities have disproportionate homicide rates. To determine the relationships between exposures to drugs and alcohol at the individual, family, and neighborhood levels and adolescent firearm homicide and to inform new approaches to preventing firearm violence. Population-based case-control study from January 2010 to December 2012 of all 13- to 20-year-olds who were homicide victims in Philadelphia during the study period matched to randomly selected 13- to 20-year-old controls from the general population. Individual drug and alcohol use at the time of injury, history of drug and alcohol use, caregiver drug and alcohol use, and neighborhood availability of alcohol and illegal drugs. We also controlled for age, race, school suspensions, arrests, and neighborhood ethnicity. Adolescent firearm homicide identified from police and medical examiner's reports. We enrolled 161 adolescent homicide cases, including 157 (97.5%) firearm homicide cases and 172 matched controls, including 166 (96.5%) firearm homicide controls. Adolescents with a history of alcohol use (adjusted odds ratio [AOR], 4.1; 95% CI, 1.2-14.0) or drug use (AOR, 4.4; 95% CI, 1.7-11.6) had increased odds of firearm homicide. Adolescents whose caregiver had a history of drug use had increased odds of firearm homicide (AOR, 11.7; 95% CI, 2.8-48.0). Adolescents in neighborhoods with high densities of alcohol outlets (AOR, 3.2; 95% CI, 1.1-9.1) and moderate or high drug availability had increased odds of firearm homicide (AOR, 3.4; 95% CI, 1.1-10.3 vs AOR, 7.5; 95% CI, 2.2-25.8). Almost all adolescent homicides in Philadelphia between 2010 and 2012 were committed with a firearm. Substance use at the individual, family, and neighborhood levels was associated with increased odds of adolescent firearm homicide; drug use was associated at all 3 levels and alcohol at the individual and neighborhood levels. Expanding violence prevention efforts to target drug and alcohol use at multiple levels may help to reduce the firearm violence that disproportionately affects adolescents in minority populations in large US cities.

The article reports on childhood predictors (explanatory, behavioral and offenses) to predict homicide offenders in the longitudinal Pittsburgh Youth Study, and compares these predictors with predictors of homicide victims in the same study. This forms the basis for formulating antecedents that are shared between homicide offenders and homicide victims at a young age (ages 7–11) and antecedents that are not shared or are unique for each. Implications of the research are highlighted for early intervention and for interventions with high-risk offenders. PMID:24122366

Falls in Scottish homicide: lessons for homicide reduction in mental health patients

Crichton, John H. M.

2017-01-01

The sustained fall in Scottish homicide rates follows crime reduction measures informed by the epidemiology of suicide. The violence reduction unit targeted young men carrying knives in public. The restriction of weapons immediately to hand appears to have caused an absolute fall in homicide just as suicide reduction was observed following changes to domestic gas supply. Further homicide reduction may be accomplished in the domestic setting with targeted changes in kitchen knife design in home safety planning for high-risk households. Most commonly homicides involving those in recent contact with mental health services in the UK have domestic characteristics and similar safety planning may be targeted at those with mental disorder and a history of violence.

Moniruzzaman, Syed; Andersson, Ragnar

2005-01-01

This study examined the association between homicide rates and GNP per capita (as a measure of economic development) among all age- and sex-specific groups in 53 countries. Cross-sectional data on homicide rates by age- and sex- specific groups were obtained for 53 countries from World Health Statistics Annual 1996. The association between homicide rates and economic development was studied by using two methods: (1) with regression analysis and (2) by categorizing the data into four income-based country groups and then comparing the differences in their mean values. Results indicate that there was a negative correlation between homicide rates and economic development. The association between homicide rates and country GNP per capita became stronger with increasing age. Pearson's product moment correlation coefficient was strongest among older age groups (65+year) in both sexes (male, r = -0.77 and female, r = -0.71). The correlation was weakest and positive among 1- to 4-year-old children (males, r = 0.17 and females, r = 0.07). The homicide rate among females was highest for <1-year-old children in low income countries (LICs) (12.8 per 100,000). Lower middle-income countries are in the stage of high priority where both homicide rates and homicide as percentage of total death are high, and its impact was greatest for young males. However, infanticide as a public health problem seems highly concentrated in the poorest countries, while homicide among small children, 1-4 years old, appears to be a universal phenomenon across all nations.

Aim of the study: To determine the circumstances which can be useful for offenders profiling in homicide cases with victim's body dismemberment. Material and methods: Study of all homicide cases with victim's corpse dismemberment examined in Krakow Department of Forensic Medicine over the last 50 years. Results: Within the past 50 years, a total number of 30 cases of homicides with dismembered bodies were examined in Krakow. 22 cases represent defensive mutilations performed by offender, 3 cases can be classified as offensive muti-lations and 3 cases represent aggressive mutilations - decapitation as a method of committing homicide. In this period the only 1 case of necrophilic mutilations was examined, when the body was dismembered without murder. In most cases the background of homicide was the family conflict, 6 was cause of mental illness of perpetrator and in 3 was sexual motive. Only in 3 cases (from 25 when the offender was known) perpetrator kill a stranger. In the other the offender belonged to the family or friends of the victim. In all cases where the perpetrator was determined, homicide and dismemberment was performed in his place of residence. The findings of the Police investigations indicate that in most cases homicides were not planned, occurred under the influence of emotion, only two have been previously scheduled. Conclusions: Homicides with corpses dismemberment usually are committed by offenders who is in close relationship with victim (family or friend). Dismemberment is almost always performed in the same place as murder - home of perpetrator. This type of homicide usually is not planned.

Mental disorders and vulnerability to homicidal death: Swedish nationwide cohort study.

To determine the risk of people with mental disorders being victims of homicide. National cohort study. Sweden. Entire adult population (n = 7,253,516). Homicidal death during eight years of follow-up (2001-08); hazard ratios for the association between mental disorders and homicidal death, with adjustment for sociodemographic confounders; potential modifying effect of comorbid substance use. 615 homicidal deaths occurred in 54.4 million person years of follow-up. Mortality rates due to homicide (per 100,000 person years) were 2.8 among people with mental disorders compared with 1.1 in the general population. After adjustment for sociodemographic confounders, any mental disorder was associated with a 4.9-fold (95% confidence interval 4.0 to 6.0) risk of homicidal death, relative to people without mental disorders. Strong associations were found irrespective of age, sex, or other sociodemographic characteristics. Although the risk of homicidal death was highest among people with substance use disorders (approximately ninefold), the risk was also increased among those with personality disorders (3.2-fold), depression (2.6-fold), anxiety disorders (2.2-fold), or schizophrenia (1.8-fold) and did not seem to be explained by comorbid substance use. Sociodemographic risk factors included male sex, being unmarried, and low socioeconomic status. In this large cohort study, people with mental disorders, including those with substance use disorders, personality disorders, depression, anxiety disorders, or schizophrenia, had greatly increased risks of homicidal death. Interventions to reduce violent death among people with mental disorders should tackle victimisation and homicidal death in addition to suicide and accidents, which share common risk factors.

Alcohol and Homicide in Russia and the United States: A Comparative Analysis*

Landberg, Jonas; Norström, Thor

2011-01-01

Objective: The object of this study was to perform a comparative analysis of the aggregate relationship between alcohol and homicide in Russia and in the United States. The comparison was based on the magnitude of the alcohol effect, the alcohol attributable fraction (AAF), and the degree to which total consumption could account for trends in homicide. Method: We analyzed total and sex-specific homicide rates for the age groups 15–64 years, 15–34 years, and 35–64 years. The study period was 1959–1998 for Russia and 1950–2002 for the United States. For the United States, alcohol consumption was gauged by sales of alcohol; for Russia, estimated unrecorded consumption was included as well. The data were analyzed through autoregressive integrated moving average (ARIMA) modeling. Results: The results show that, for Russia as well as for the United States, a 1 -L increase in consumption was associated with an increase in homicides of about 10%, although the absolute effect was markedly larger in Russia because of differences in homicide rates. The AAF estimates suggested that 73% and 57% of the homicides would be attributable to alcohol in Russia and in the United States, respectively. Most of the temporal variation in the Russian homicide rate could be accounted for by the trend in drinking, whereas the U.S. trend in total alcohol consumption had a more limited ability to predict the trend in homicides. Conclusions: We conclude that the role of alcohol in homicide seems to be larger in Russia than in the United States. PMID:21906499

To describe age- and sex-specific rates of child homicide in South Africa. A cross-sectional mortuary-based study was conducted in a national sample of 38 medicolegal laboratories operating in 2009. These were sampled in inverse proportion to the number that were operational in each of three strata defined by autopsy volume: < 500, 500-1499 or > 1499 annual autopsies. Child homicide data were collected from mortuary files, autopsy reports and police interviews. Cause of death, evidence of abuse and neglect or of sexual assault, perpetrator characteristics and circumstances surrounding the death were investigated. An estimated 1018 (95% confidence interval, CI: 843-1187) child homicides occurred in 2009, for a rate of 5.5 (95% CI: 4.6-6.4) homicides per 100 000 children younger than 18 years. The homicide rate was much higher in boys (6.9 per 100 000; 95% CI: 5.6-8.3) than in girls (3.9 per 100 000; 95% CI: 3.2-4.7). Child abuse and neglect had preceded nearly half (44.5%) of all homicides, but three times more often among girls than among boys. In children aged 15 to 17 years, the homicide rate among boys (21.7 per 100 000; 95% CI: 14.2-29.2) was nearly five times higher than the homicide rate among girls (4.6 per 100 000; 95% CI: 2.4-6.8). South Africa's child homicide rate is more than twice the global estimate. Since a background of child abuse and neglect is common, improvement of parenting skills should be part of primary prevention efforts.

Misdemeanor policing, physical disorder, and gun-related homicide: a spatial analytic test of "broken-windows" theory.

Homicide contributes substantially to the burden of death in the US and remains a key contributor to the gap in white-black life expectancy. It has been hypothesized that "broken-windows" policing is associated with lower homicide rates and that physical disorder may mediate this association. However, the empiric evidence is limited and conflicting. We used pooled, cross-sectional time-series data for 74 New York City (NYC) Police Precincts between 1990 and 1999 to test the relation between neighborhood misdemeanor policing (an indicator of physical order) and homicide in NYC in the 1990s. We applied Bayesian hierarchical models, including a random effect of place, to account for serial correlations in homicide across adjacent neighborhoods. An increase of 5000 misdemeanor arrests in a precinct with 100,000 people was associated with a reduction of 3.5 homicides (95% credible interval = -5.00 to -1.00). However, increased misdemeanor arrests were associated with lower physical order (posterior median = -0.015 [-0.025 to -0.01]), and physical order was unrelated to homicide. Our study replicated prior findings suggesting that misdemeanor policing reduces homicide rates, but offered no support for the hypothesis that physical disorder is a mediator of the impact of such policing. Factors responsible for the dramatic decline in US homicides in the last decade remain unclear.

Homicides by people with mental illness have been studied using either clinical or legal categorization of the homicide as abnormal. No previous study has employed both definitions in the same population. A retrospective study of all homicides in New Zealand between 1988 and 2000 considered mentally abnormal homicide using a legal definition (when the courts deemed a contribution of mental illness was present) and a clinical definition (defined as the presence of a discharge diagnosis from inpatient mental health treatment) of 'mentally abnormal'. Rates, characteristics and time trends were investigated. Of the 844 cases, 7.1% met legal criteria for being mentally abnormal, while 7.7% had ever received a diagnosis for a psychotic illness, and a further 14.5% had been admitted to a psychiatric hospital for any other reason. The majority (60%) of perpetrators with a psychotic diagnosis received a mental health disposition from the court. Of these, 60% were first diagnosed with their psychotic illness prior to the homicide, while 28% were first diagnosed at the time of the offence and a further 12% after imprisonment. Of all those who received a psychotic diagnosis, 89% had post-conviction admissions or a mental health disposition. Legal and clinical definitions of mentally abnormal homicide detect similar rates of mentally abnormal homicide, but illustrate somewhat different dimensions of the relationship between mental illness and homicide.

Homicide is a universal indicator of social violence with large public health consequences. To describe mortality by homicides and to analyze its trends and geographic distribution in Colombia between 1998 and 2012. We conducted a descriptive study of deaths by homicide in Colombia between 1998 and 2012 using official mortality databases and the population projections of the Departamento Administrativo Nacional de Estadística, DANE. We calculated age- and sex-specific mortality rates, and we analyzed the geographical distribution of mean-adjusted homicide mortality rates at municipal level. Between 1998 and 2012, 331,470 homicides were reported in Colombia. The mean crude rate was 51.5 per 100,000 inhabitants: 95.9 in men and 8.2 in women. Since 2003, a decrease in the number of deaths and rates was observed; 91.9% of the victims were men and the highest mortality rates were reported in the 20-29 years old group. The most frequently involved mechanism was the firearm: Eight of 10 homicides in men, and seven of 10 homicides in women. Out of 1,122 municipalities, 186 were in the highest quintile, accumulating 50.1% of all deaths. In Colombia, homicides have been one of the leading causes of death with a trend towards reduction since 2002. Its geographical distribution has been heterogeneous. To continue addressing this public health issue we must recur to multidisciplinary analytical methodologies for a better understanding of the phenomenon.

The distinction between self-inflicted blade wounds and blade wounds inflicted by another can be difficult in situations where there is little available history or context. We reviewed homicides and suicides in the past 10 years at the Vermont Office of the Chief Medical Examiner to define the characteristics of homicidal and suicidal blade wounds. All homicides and suicides involving blade wounds, not just those in which blade wounds were the cause of death, were included. Information regarding victim demographics, location and type of injuries, toxicology, and evidence of suicidality was gathered. Blade wounds were the cause of death in 85.7% of homicides but only in 36% of suicides. Hanging and gunshot wounds were the cause of death in 28% and 24% of suicides, respectively. Multiple stab wounds were found in 10% of homicides and in 0% of suicides, whereas multiple incised wounds were found in 60% of suicides and only 10% of homicides. However, several unusual instances of suicide were found, including suicides with clothing damage or bone or cartilage injury from blade wounds. No characteristics of blade wounds were definitive for homicide or suicide. History and circumstances of the scene are thus crucial in determining the manner of death.

Objectives. In the United States, state firearm ownership has been correlated with homicide rates. More than 90% of homicides of law enforcement officers (LEOs) are committed with firearms. We examined the relationship between state firearm ownership rates and LEO occupational homicide rates. Methods. We obtained the number LEOs killed from 1996 to 2010 from a Federal Bureau of Investigation (FBI) database. We calculated homicide rates per state as the number of officers killed per number of LEOs per state, obtained from another FBI database. We obtained the mean household firearm ownership for each state from the Behavioral Risk Factor Surveillance System. Results. Using Poisson regression and controlling for factors known to affect homicide rates, we associated firearm ownership with the homicide rates for LEOs (incidence rate ratio = 1.044; P = .005); our results were supported by cross-sectional and longitudinal sensitivity analyses. LEO homicide rates were 3 times higher in states with high firearm ownership compared with states with low firearm ownership. Conclusions. High public gun ownership is a risk for occupational mortality for LEOs in the United States. States could consider methods for reducing firearm ownership as a way to reduce occupational deaths of LEOs. PMID:26270316

The objective was to evaluate correlations between suicide, homicide and socio-demographic variables by an ecological study. Mortality and socio-demographic data were collected from official records of the Ministry of Health and IBGE (2010), aggregated by state (27). The data were analyzed using correlation techniques, factor analysis, principal component analysis with a varimax rotation and multiple linear regression. Suicide age-adjusted rates for the total population, men and women were 5.0, 8.0, and 2.2 per 100,000 inhabitants respectively. The suicide rates ranged from 2.7 in Pará to 9.1 in Rio Grande do Sul. Homicide for the total population, men and women were 27.2, 50.8, and 4.5 per 100,000, respectively. The homicide rates ranged from 13.0 in Santa Catarina to 68.9 in Alagoas. Suicide and homicide were negatively associated, the significance persisted among men. Unemployment was negatively correlated with suicide and positively with homicide. Different socio-demographic variables were found to correlate with suicide and homicide in the regressions. Suicide showed a pattern suggesting that, in Brazil, it is related to high socioeconomic status. Homicide seemed to follow the pattern found in other countries, associated with lower social and economic status.

Emerging correlations between measures of population well-being, suicide and homicide: a look at global and Australian data.

Our aim was (1) to examine global and Australian data with a view to determining the presence of an inverse relationship between suicide and homicide rates, and (2) to examine global Human Development Index (HDI) values and suicide and homicide rates, with a view to determining any statistical relationship. Suicide and homicide rates and HDI values were available for 102 countries, and suicide and homicide rates were available for the states and territories of Australia. The three data sets had non-normal distributions, and the non-parametric Spearman's ρ was used for correlation statistics with α = 0.05. We found a weak, statistically significant inverse relationship between the suicide and homicide rates of 102 countries (ρ = -0.244, p = 0.014). No relationship was established for the Australian values, however. As anticipated, we found a significant negative correlation between homicide and HDI values. We unexpectedly demonstrated a positive correlation between suicide rates and HDI values. The notion that suicide and homicide have an inverse relationship now has some scientific support; but additional research is warranted to characterise and explain this relationship. The unexpected finding of a positive correlation between suicide rates and HDI values requires further examination.

Background Many legal residents in the United States (US)-Mexico border region cross from the US into Mexico for medical treatment and pharmaceuticals. We analyzed whether recent increases in homicides in Mexico are associated with reduced healthcare access for US border residents. Methods We used data on healthcare access, legal entries to the US from Mexico, and Mexican homicide rates (2002–2010). Poisson regression models estimated associations between homicide rates and total legal US entries. Multivariate difference-in-difference linear probability models evaluated associations between Mexican homicide rates and self-reported measures of healthcare access for US residents. Results Increased homicide rates were associated with decreased legal entries to the US from Mexico. Contrary to expectations, homicides did not have significant associations with healthcare access measures for legal residents in US border counties. Conclusions Despite a decrease in border crossings, increased violence in Mexico did not appear to negatively affect access for US border residents. PMID:24917240

The current study evaluated a range of social influences including misdemeanor arrests, drug arrests, cocaine consumption, alcohol consumption, firearm availability, and incarceration that may be associated with changes in gun-related homicides by racial/ethnic group in New York City (NYC) from 1990 to 1999. Using police precincts as the unit of analysis, we used cross-sectional, time series data to examine changes in Black, White, and Hispanic homicides, separately. Bayesian hierarchical models with a spatial error term indicated that an increase in cocaine consumption was associated with an increase in Black homicides. An increase in firearm availability was associated with an increase in Hispanic homicides. Last, there were no significant predictors for White homicides. Support was found for the crack cocaine hypotheses but not for the broken windows hypothesis. Examining racially/ethnically disaggregated data can shed light on group-sensitive mechanisms that may explain changes in homicide over time. PMID:22328820

Violence disproportionately affects low- and middle-income countries. Deeper understanding is needed in areas where little research has occurred. The objectives of the study were to: (a) ascertain rate of homicide death; (b) describe the victims and circumstances surrounding their deaths in Dar es Salaam, Tanzania in 2005. This study was developed by adapting the WHO/CDC Injury Surveillance Guidelines (Holder et al., 2001). Data on 12 variables were collected on all homicide deaths. Descriptive statistics and hypothesis tests were done when appropriate. Age standardised, age-specific and cause-specific mortality rates are presented. The overall homicide rate was 12.57 (males and females respectively: 22.26 and 2.64). Homicide deaths were 93.4% male, mostly unemployed, with a mean age of 28.2 years. Most deaths occurred in urban areas. Mob violence was the cause of 57% of deaths. The risk of homicide death for males was greater than the world average, but for females it was less. Most homicides were committed by community members policing against thieves.

Homicide followed by the suicide of the murderer is a relatively rare lethal incident in which an individual kills another person and subsequently dies by suicide. Cases involving a homicide and a suicide in which death examinations and autopsies were performed at The Konya Branch of the Forensic Medicine Council between 2000 and 2007 were retrospectively investigated. During the studied time period, there were 10 homicide-suicide cases identified with 10 perpetrators killing 12 victims. Nine of the perpetrators were men and eight of the victims were women. The precipitating motive was an impending divorce in four of the cases. Two perpetrators were described as severely depressed, one had a diagnosis of antisocial personality disorder, and one was a pedophile who had reactive depression. Firearms were used in eight of the homicide cases and seven of the suicides. Constricting the use of firearms may reduce/prevent future homicide-suicide cases, as it is the most commonly used method to carry out homicide-suicides.

Patterns of non-firearm homicide.

Sixty-two recent non-firearm homicides dealt with by an inner London public mortuary were studied. The majority of homicides involved stabbing--usually multiple wounds to the trunk. These were followed by blunt instrument homicides--nearly all involved multiple blows to the head, and asphyxiation--usually consisting of strangulation with a ligature being employed in the majority of cases. Homicides tended to occur during the evening and night in spring and early summer. Most victims were found to be in the 20-39 age group, with male victims outnumbering females in a 2:1 ratio. A marked difference in homicide pattern existed between the male and female victims. Males tended to fall victim to strangers encountered while socialising in and around bars and clubs. Females were most often killed by close acquaintances in domestic disputes at home.

The aim of this study was to examine the nature of homicide-suicides and determine the ways in which they differ from suicides without the perpetration of homicide in terms of their demographic characteristics, suicide, medical and psychiatric history, their psychological state leading up to the suicide, and their motives for their suicidal behavior. Cases of homicide-suicide from a 20-year period were extracted from the Coroner's inquest files and were matched to suicide-only cases on the basis of age and sex. The characteristics that predominantly distinguished the homicide-suicides were based on psychological state leading up to the act and motive for the act. It is proposed that homicide-suicides may be better understood within an expressive homicide framework. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Understanding Homicide-Suicide.

Knoll, James L

2016-12-01

Homicide-suicide is the phenomenon in which an individual kills 1 or more people and commits suicide. Research on homicide-suicide has been hampered by a lack of an accepted classification scheme and reliance on media reports. Mass murder-suicide is gaining increasing attention particularly in the United States. This article reviews the research and literature on homicide-suicide, proposing a standard classification scheme. Preventive methods are discussed and sociocultural factors explored. For a more accurate and complete understanding of homicide-suicide, it is argued that future research should use the full psychological autopsy approach, to include collateral interviews.

IMPORTANCE Homicide is the third leading cause of death for adolescents in the United States and the leading cause of death for adolescents who are African American. Large cities have disproportionate homicide rates. OBJECTIVE To determine the relationships between exposures to drugs and alcohol at the individual, family, and neighborhood levels and adolescent firearm homicide and to inform new approaches to preventing firearm violence. DESIGN, SETTING, AND PARTICIPANTS Population-based case-control study from January 2010 to December 2012 of all 13- to 20-year-olds who were homicide victims in Philadelphia during the study period matched to randomly selected 13- to 20-year-old controls from the general population. EXPOSURES Individual drug and alcohol use at the time of injury, history of drug and alcohol use, caregiver drug and alcohol use, and neighborhood availability of alcohol and illegal drugs. We also controlled for age, race, school suspensions, arrests, and neighborhood ethnicity. MAIN OUTCOMES AND MEASURES Adolescent firearm homicide identified from police and medical examiner’s reports. RESULTS We enrolled 161 adolescent homicide cases, including 157 (97.5%) firearm homicide cases and 172 matched controls, including 166 (96.5%) firearm homicide controls. Adolescents with a history of alcohol use (adjusted odds ratio [AOR], 4.1; 95% CI, 1.2–14.0) or drug use (AOR, 4.4; 95% CI, 1.7–11.6) had increased odds of firearm homicide. Adolescents whose caregiver had a history of drug use had increased odds of firearm homicide (AOR, 11.7; 95% CI, 2.8–48.0). Adolescents in neighborhoods with high densities of alcohol outlets (AOR, 3.2; 95% CI, 1.1–9.1) and moderate or high drug availability had increased odds of firearm homicide (AOR, 3.4; 95% CI, 1.1–10.3 vs AOR, 7.5; 95% CI, 2.2–25.8). CONCLUSIONS AND RELEVANCE Almost all adolescent homicides in Philadelphia between 2010 and 2012 were committed with a firearm. Substance use at the individual, family, and neighborhood levels was associated with increased odds of adolescent firearm homicide; drug use was associated at all 3 levels and alcohol at the individual and neighborhood levels. Expanding violence prevention efforts to target drug and alcohol use at multiple levels may help to reduce the firearm violence that disproportionately affects adolescents in minority populations in large US cities.

One of the oldest crimes in human civilization is homicide which started from murder of Abel by the hands of Cane. With the passage of time manner of homicide have been changing. Study of pattern of homicide in any civil society is the first step towards development of intervention to reduce the impact of homicidal crimes. This study was conducted at the department of forensic medicine and toxicology Gomal Medical College DI Khan to know the pattern of the homicides, taking it as the first step in the prevention of crime. The present study was conducted over two years 2007-08. The data collected includes all reported unnatural deaths from the urban and rural areas of district on which autopsies were conducted in the district headquarter teaching hospital DI Khan and department of Forensic Medicine and Toxicology, Gomal Medical College DL Khan. Homicidal deaths constituted 259/341 (76%) of all autopsies. Out of these homicides 59.07% were caused by the firearm. The most common firearm weapons were high velocity rifled weapons (AK-47, rifles and pistols). A total of 304 injuries were found in various body regions giving an average of about two injuries per victim/person. The head, neck and face sustained the highest numbers of injuries 100, (32.90%) followed by chest 91 (29.93%) and abdomen 47 (15.4%); the extremities, buttock and genitalia together sustained 65 (21.38 %) injuries. A part from firearm injuries unfortunately in our this study the second highest cause of homicidal deaths was bomb blasts injuries either due to suicide bombers or remote control bombs. The numbers of deaths due to blast injuries were 82 for the year 2007/08 out of total homicidal deaths and percentage was 32.66%. The vast majority of homicidal deaths in this area are caused by firearms like other big cities of the province like Peshawar, which bring up issues related to possession of firearms and change in cultural attitude towards the use of firearm, if a decrease in firearm related homicides is desired.

Female intimate partner homicide (FIPH) is a fatal complication of domestic violence. The aim of this study was to describe the socio-demographic, clinical and criminological characteristics of male perpetrators of FIPH and to compare them to the perpetrators of extrafamilial homicide and the perpetrators of intrafamilial homicide other than FIPH. Between 1975 and 2005, 32 FIPH were perpetrated in the region of Angers (France), and these were compared to 26 intrafamilial homicides other than FIPH and to 97 extrafamilial homicides perpetrated in the same period, in the same region. The socio-demographic, clinical and criminological data were collected from psychiatric expert reports and medical files. The mean age of the FIPH perpetrators was 37.8years. They were professionally active, in majority as manual workers. They had a psychiatric record (69%), a previous criminal record (31%), and a history of violence against others (47%). Half of these perpetrators also had experienced a traumatic event before the age of 18. Compared to extrafamilial homicide perpetrators, FIPH perpetrators occupied more frequently a manual job and had prior criminal records less frequently. In the majority of cases of FIPH and intrafamilial homicide, the murder occurred in the evening, at the victim's home, and while the perpetrator was intoxicated. FIPH was mostly premeditated and was accompanied four times less frequently by another criminal behaviour compared to extrafamilial homicide. The FIPH perpetrators had more depressive symptoms and suicidal ideations when committing the crime and remained on the crime scene more often than extrafamilial homicide perpetrators who mostly attempted to flee the crime scene. FIPH perpetrators and extra- and intrafamilial homicide perpetrators were found criminally responsible in half of the cases. The socio-demographic, clinical and criminological characteristics of FIPH perpetrators were not statistically different from those of perpetrators of another intrafamilial homicide except that conflict preceded FIPH more frequently. Identification of specific features of FIPH could contribute to the early identification of domestic violence at risk of becoming lethal and to the elaboration of preventive strategies.

2017-07-01

We aimed to assess the extent to which adherence to, and recreational use of, psychotropic medications influence the risk of homicide offending and victimization. We conducted a population-based case-control study by way of linking a nationwide registry of dispensed prescriptions with a forensic-toxicological database. Homicide victims (n = 200) and offenders (n = 105) were identified for the years 2007-2009 and vehicle-accident controls (n = 1,643) for the years 2006-2013. The occurrence of congruence and incongruence between dispensed prescriptions and toxicology was used as a measure of adherence and recreational use. For antidepressants, incongruence-but not congruence-between dispensed prescriptions and toxicology was associated with a significantly increased risk of homicide offending (odds ratio adjusted for age and sex [aOR] = 6.2; 95% confidence interval [CI], 3.3-11.6) but not homicide victimization (aOR = 0.8; 95% CI, 0.3-2.0). For antipsychotics and mood stabilizers, a significantly increased risk of homicide offending was associated with incongruence between prescriptions and toxicology (aOR = 7.0; 95% CI, 2.8-17.7), whereas risk estimates for congruence were not significantly elevated for either homicide offending or victimization. For GABAergic hypnotics, congruence and incongruence were significantly associated with increased risks of both homicide offending (aOR = 5.4; 95% CI, 2.6-11.0 and aOR = 4.9; 95% CI, 2.6-9.3, respectively) and homicide victimization (aOR = 2.1; 95% CI, 1.1-4.2 and aOR = 3.2; 95% CI, 1.7-6.1, respectively). Sensitivity analyses with a subset of controls yielded similar estimates. Nonadherence to medications used to treat affective and psychotic disorders appears to elevate the risk of homicide offending. Both medicinal and recreational use of GABAergic hypnotics appears to elevate the risk of homicide offending and victimization. In summary, vigilance regarding adherence to medications prescribed for mood disorders and psychosis, as well as restrictiveness regarding licit and illicit access to addictive hypnotics, might contribute to a reduction of homicidal violence. © Copyright 2017 Physicians Postgraduate Press, Inc.

In the context of violence against women, intimate partner homicide increasingly receives research and policy attention. Although the impact of losing a parent due to intimate partner homicide is intuitively obvious, little is known about the children involved. We aimed to identify all children bereaved by parental intimate partner homicide in the Netherlands in the period 2003-2012, describe their demographics and family circumstances, and assess their exposure to prior violence at home and to the homicide itself. We cross-examined 8 national data sources and extracted data about children's demographics and circumstances prior to, and during the homicide. Our primary outcomes were prior violence at home (child maltreatment, neglect or domestic violence) and homicide witness status (ranging from being at a different location altogether to being present at the scene). During the decade under study, 256 children lost a biological parent due to 137 cases of intimate partner homicide. On average, the children were 7.4 years old at the time of the homicide (51.1% were boys; 95% CI 47.3-54.7) and most lost their mother (87.1%; full population data). Immigrant children were overrepresented (59.4%; 95% CI 52.8-66.0). Of the children for whom information about previous violence at home was gathered, 67.7% (95% CI 59.7-73.7) were certainly exposed and 16.7% (95% CI 11.3-22.2) probably. Of the children who had certainly been exposed, 43.1% (95% CI 41.1-60.9) had not received social services or mental health care. The majority of the children (58.7%; 95% CI 52.1-65.3) were present at the location of the homicide when the killing took place, with varying levels of exposure. Homicide weapons mostly involved cutting weapons and firearms, leading to graphic crime scenes. Care providers need capacity not only to help children cope with the sudden loss of a parent but also with unaddressed histories of domestic violence and exposure to graphic homicide scenes, in a culture-sensitive way. Future directions include longitudinal monitoring of children's mental health outcomes and replication in other countries.

Killing the canary: the international epidemiology of the homicide of media workers.

To describe the international epidemiology of the homicide of media workers, and investigate country-level risk factors. Data on the homicides occurring from 2002 to 2006 were collected and collated from five international databases. Analyses included consideration of seven existing international indices relating to human development, and to the social and political functioning of states. During the 5-year period, 370 deaths in 54 countries met our definitions of homicides and media workers. Almost all (89%) were nationals of the country in which they died. The annual number of such homicides globally has more than doubled, from 41 in 2002 to 104 in 2006 (including 49 in Iraq in 2006). Less than 25% of the homicides of media workers over the last 5 years have resulted in an arrest or prosecution. Statistically significant associations (p<0.001; Political Terror Scores, OR 1.15; Corruption Perceptions Index, OR 0.53; Overall Failed State Index, OR 1.05; Failed State Index 7, OR 1.52; Failed State Index 9, OR 1.55; Failed State Index 10, OR 1.61) were found on logistic regression between the occurrence of the homicide of media workers in countries and scoring on six of the seven indices associated with country-level sociopolitical development. These indices reflected high levels of political terror and corruption, low government legitimisation, poor human rights, and uncontrolled armed groups. However, in terms of the homicide rate for countries, these associations were significant for only four of the seven indices (the general functionality of government, ability of governments to control armed groups, the level of political terror, and the level of violation of rights). The homicide of media workers increased substantially in this 5-year period and was found to be particularly concentrated in selected countries such as Iraq. The authors were able to identify specific sociopolitical risk factors for homicide occurrence, and for homicide rates at the country level.

The extent to which differences in homicide and suicide rates in black versus white men vary by U.S. state is unknown. To compare the rates of firearm and nonfirearm homicide and suicide in black and white non-Hispanic men by U.S. state and to examine whether these deaths are associated with state prevalence of gun ownership. Surveillance study. 50 states and the District of Columbia, 2008 to 2016. Cause-of-death data were abstracted by using the Centers for Disease Control and Prevention's WONDER (Wide-ranging Online Data for Epidemiologic Research) database. Non-Hispanic black and non-Hispanic white males, all ages. Absolute rates of and rate differences in firearm and nonfirearm homicide and suicide in black and white men. During the 9-year study period, 84 113 homicides and 251 772 suicides occurred. Black-white differences in rates of firearm homicide and suicide varied widely across states. Relative to white men, black men had between 9 and 57 additional firearm homicides per 100 000 per year, with black men in Missouri, Michigan, Illinois, Indiana, and Pennsylvania having more than 40 additional firearm homicides per 100 000 per year. White men had between 2 fewer and 16 more firearm suicides per 100 000 per year, with the largest inequalities observed in southern and western states and the smallest in the District of Columbia and densely populated northeastern states. Some homicides and suicides may have been misclassified as deaths due to unintentional injury. Survey data on state household gun ownership were collected in 2004 and may have shifted during the past decade. The large state-to-state variation in firearm homicide and suicide rates, as well as the racial inequalities in these numbers, highlights states where policies may be most beneficial in reducing homicide and suicide deaths and the racial disparities in their rates.

The study considers whether involuntary civil comment (ICC) statute provisions are associated with homicide rates. Do statutes based solely upon dangerousness criteria versus broader ICC-criteria-i.e. "need for treatment," "protection of health and safety," and family protection-have differential associations related to their goal of reducing the frequency of homicide? State-level data were obtained from online data bases and key-informant surveys. Ordinary-least-squares and Poisson regression were used to evaluate the association between statute characteristics, mental health system characteristics, and 2004 Homicide Rates after controlling for firearm-control-law restrictiveness and social-economic-demographic-geographic-and-political indicators historically related to homicide rate variation. Poisson and OLS models, respectively, were significant: likelihood ratio χ(2) = 108.47, df = 10; p < 0.000 and Adj. R (2) = 0.72; df = 10, 25; F = 10.21; p < 0.000. Poisson results indicate that social-economic-demographic-geographic-and-political-indicators had the strongest association with state homicide rates (p < 0.000). Lower rates were associated with: broader ICC-criteria (p ≤ 0.01), fewer inpatient-bed access problems (p ≤ 0.03), and better mental health system ratings (p ≤ 0.04). OLS results indicate that social-economic-demographic-geographic-and-political indicators accounted for 25% of homicide rate variation. Broader ICC-criteria were associated with 1.42 less homicides per 100,000. Less access to psychiatric inpatient-beds and more poorly rated mental health systems were associated with increases in the homicide rates of 1.08 and 0.26 per 100,000, respectively. While social-economic-demographic-geographic-and-political indicators show the strongest association with homicide rate variation, the results show the importance and potentially preventive utility of broader ICC criteria, increased psychiatric inpatient-bed access, and better performing mental health systems as factors contributing to homicide rate variation.

To raise awareness of the impact of homicides in Puerto Rico based on the findings of the spatial and temporal distribution of homicides and the use of firearms, by age and gender, using reports of interpersonal violent deaths from the Institute of Forensic Science (IFS) headquartered in San Juan, Puerto Rico. This was a descriptive study of all homicide incidents in Puerto Rico reported by the IFS for the period 2001-2010. For each of the 8 542 cases, data analyzed included age, sex, municipality of incident, date of death, and mechanism. Crude sex- and age-specific mortality rates for Puerto Rico and for each municipality per year and for the 10-year period were calculated. Cumulative rate and cumulative risks were estimated and defined as lifetime risk. The relative distribution of cumulative rates for each municipality was categorized into quartiles of highest to lowest risk and displayed as a map. The risk of homicide death among males is 13 times greater than among females. The highest rates were observed among males 20-24 years of age (198.4 homicides per 100 000). In any given year, firearms were used in at least 80% of homicides. The average lifetime risk of homicide death for males is 1 in 34. Young adult males with access to firearms are at greatest risk of homicide in Puerto Rico. Also, highly urbanized municipalities are at highest risk; however, certain non-urban municipalities along the coast also have a very high homicide risk. Top priorities should be applying the WHO "ecological model" for violent injury prevention and establishing a surveillance system that will assist in identifying the role that socioeconomics, illegal firearms trade, and drug trafficking are playing.

Abstract Objective To describe age- and sex-specific rates of child homicide in South Africa. Methods A cross-sectional mortuary-based study was conducted in a national sample of 38 medicolegal laboratories operating in 2009. These were sampled in inverse proportion to the number that were operational in each of three strata defined by autopsy volume: < 500, 500–1499 or > 1499 annual autopsies. Child homicide data were collected from mortuary files, autopsy reports and police interviews. Cause of death, evidence of abuse and neglect or of sexual assault, perpetrator characteristics and circumstances surrounding the death were investigated. Findings An estimated 1018 (95% confidence interval, CI: 843–1187) child homicides occurred in 2009, for a rate of 5.5 (95% CI: 4.6–6.4) homicides per 100 000 children younger than 18 years. The homicide rate was much higher in boys (6.9 per 100 000; 95% CI: 5.6–8.3) than in girls (3.9 per 100 000; 95% CI: 3.2–4.7). Child abuse and neglect had preceded nearly half (44.5%) of all homicides, but three times more often among girls than among boys. In children aged 15 to 17 years, the homicide rate among boys (21.7 per 100 000; 95% CI: 14.2–29.2) was nearly five times higher than the homicide rate among girls (4.6 per 100 000; 95% CI: 2.4–6.8). Conclusion South Africa’s child homicide rate is more than twice the global estimate. Since a background of child abuse and neglect is common, improvement of parenting skills should be part of primary prevention efforts. PMID:23940403

The nature of newspaper coverage of homicide

2002-01-01

Objectives: Previous research has shown that some homicides are more likely than others to receive newspaper coverage (for example, homicides by strangers). The present investigation examined whether, once the decision has been made to report on a homicide, the nature of the coverage (that is, how much visibility is given to a story, what information is included, and how a story is written) differs according to two key variables, victim ethnicity, and victim-suspect relationship. Setting: Los Angeles, California (USA). Methods: Homicide articles from the 1990–94 issues of the Los Angeles Times were stratified according to the predictors of interest (victim ethnicity and victim-suspect relationship) and a sample was drawn. Data that characterized two primary aspects of newspaper coverage, prominence and story framing (including background information, story focus, use of opinions, story tone, and "hook" or leading introductory lines) were abstracted from the articles. Descriptive statistics and cross tabulations were generated. Multivariate analyses were conducted to examine the predictive value of victim ethnicity and victim-suspect relationship on the nature of the newspaper coverage. Results: Newspaper coverage of homicide was generally factual, episodic, and unemotional in tone. Victim-suspect relationship, but not victim ethnicity, was related to how a story was covered, particularly the story frame. Homicides by intimates were covered consistently differently from other types of homicides; these stories were less likely to be opinion dominated, be emotional, and begin with a "hook". Conclusion: Victim-suspect relationship was related to the nature of coverage of homicides in a large, metropolitan newspaper. Given the agenda setting and issue framing functions of the news media, these findings have implications for the manner in which the public and policy makers perceive homicides and, consequently, for the support afforded to various types of solutions for addressing and preventing violence.

Objective Homicide and suicide are two important and potentially preventable causes of maternal injury. We analyzed data from the National Violent Death Reporting System to estimate the rates of pregnancy-associated homicide and suicide in a multi-state sample, to compare these rates with other causes of maternal mortality, and to describe victims’ demographic characteristics. Methods We analyzed data from female victims of reproductive age from 2003–2007. We identified pregnancy-associated violent deaths as deaths due to homicide or suicide during pregnancy or within the first year postpartum. We calculated the rates of pregnancy-associated homicide and suicide as the number of deaths per 100,000 live births in the sample population. We used descriptive statistics to report victims’ demographic characteristics and prevalence of intimate partner violence (IPV). Results There were 94 counts of pregnancy-associated suicide and 139 counts of pregnancy-associated homicide, yielding pregnancy-associated suicide and homicide rates of 2.0 and 2.9 deaths/100,000 live births, respectively. Victims of pregnancy-associated suicide were significantly more likely to be older and of Caucasian or American Indian descent as compared to all live births in NVDRS states. Pregnancy-associated homicide victims were significantly more likely to be at the extremes of the age range and African American. 54.3% of pregnancy-associated suicides involved intimate partner conflict that appeared to contribute to the suicide. 45.3% of pregnancy-associated homicides were IPV-associated. Conclusions Our results indicate that pregnancy-associated homicide and suicide are important contributors to maternal mortality and confirm the need to evaluate the relationships between socio demographic disparities and IPV with pregnancy-associated violent death.

The Departments of Forensic Medicine and Science at the University of Glasgow and the Victorian Institute of Forensic Medicine in Melbourne are academic university-based forensic medicine units providing a medico-legal death investigation service to the Strathclyde region of Scotland and the State of Victoria, Australia, respectively. We reviewed and compared homicides in the two jurisdictions for the year 2005. Whilst gross numbers were comparable, the homicide rate per capita was significantly higher in Glasgow. Death due to stabbing comprised a greater proportion of homicides in Glasgow, reflective of a well recognised social epidemic of knife-related trauma amongst young males. Blunt force trauma was the most prevalent cause of homicidal injury in the Australian cases. The cities shared a low incidence of firearm- related homicide, reflective of strict legislative initiatives.

To identify the existence of spatial and temporal patterns in the occurrence of intentional homicides in the municipality of São Paulo (MSP), Brazil, and to discuss the analytical value of taking such patterns into account when designing studies that address the dynamics and factors associated with the incidence of homicides. A longitudinal ecological study was conducted, having as units of analysis 13 205 census tracts and the 96 census districts that congregate these sectors in São Paulo. All intentional homicides reported in the city between 2000 and 2008 were analyzed. The gross homicide rates per 100 000 population was calculated as well as the global and local Bayesian estimates for each census tract during the study period. To verify the possibility of identifying different patterns of the spatial distribution of homicides, we used BoxMap and Moran's I index. The homicide trends in the city of São Paulo in the last decade were not homogeneous and systematic. Instead, seven patterns of spatial distribution were identified; that is, seven spatial regimes for the occurrence of intentional homicides, considering the homicide rates within each census tract as well as the rates in adjacent tracts. These spatial distribution regimes were not contained within the limits of the census tracts and districts. The results show the importance of analyzing the spatial distribution of social phenomena without restriction of political and administrative boundaries.

PURPOSE Intimate partner violence (IPV) is an important public health issue with serious consequences for the workplace. Workplace homicides occurring to U.S. women over a 6-year period, including those perpetrated by an intimate partner, are described. METHODS Workplace homicides among U.S. women from 2003 to 2008 were categorized into type I (criminal intent), type II (customer/client), type III (co-worker), or type IV (personal relations) events using the Census of Fatal Occupational Injuries. Fatality rates were calculated and compared among workplace violence (WPV) types, occupations, and characteristics including location of homicide, type of workplace, time of day, and weapon used. RESULTS Between 2003 and 2008, 648 women were feloniously killed on the job. The leading cause of workplace homicide for U.S. women was criminal intent, such as robbing a store (n = 212; 39%), followed by homicides perpetrated by a personal relation (n= 181; 33%). The majority of these personal relations were intimate partners (n = 142; 78%). Over half of workplace homicides perpetrated by intimate partners occurred in parking lots and public buildings (n = 91; 51%). CONCLUSIONS A large percentage of homicides occurring to women at work are perpetrated by intimate partners. WPV prevention programs should incorporate strategies to prevent and respond to IPV.

Fountoulakis, Konstantinos N; Gonda, Xenia

2017-03-01

The current study investigated the relationship of suicide and homicide rates internationally. WHO database mortality data for 82 countries concerning suicide, homicides, and cancer and traffic accidents as controls were used. The analysis included Pearson correlation and multiple linear regression analysis. Worldwide homicidal rates explained 55.42%, 43.86% and 41.7% of male and 22.0%, 22.14% and 13.25% of female suicides for 2000, 2005 and 2010 respectively. In Europe there was a positive correlation between male suicide rates and all homicide rates including homicide rates in both genders, in male victims, and in female victims. In America there is no significant correlation. In Asia there is a significant correlation of male suicidal rates only with homicide rates of female victims. We observed marked and interesting differences in the pattern of association between Europe and the Americas. Overall the current paper suggests that at least in some human populations, suicidality and homicidality share common etiopathogenetic substrates and could be triggered by the same internal or external events or might develop based on common genetic background. Empirically it has been suggested that suicide is related to higher living standards while murder is related to poor quality of life and lower living standards. Copyright © 2017 Elsevier Ireland Ltd.

Open-Source Data and the Study of Homicide.

Parkin, William S; Gruenewald, Jeff

To date, no discussion has taken place in the social sciences as to the appropriateness of using open-source data to augment, or replace, official data sources in homicide research. The purpose of this article is to examine whether open-source data have the potential to be used as a valid and reliable data source in testing theory and studying homicide. Official and open-source homicide data were collected as a case study in a single jurisdiction over a 1-year period. The data sets were compared to determine whether open-sources could recreate the population of homicides and variable responses collected in official data. Open-source data were able to replicate the population of homicides identified in the official data. Also, for every variable measured, the open-sources captured as much, or more, of the information presented in the official data. Also, variables not available in official data, but potentially useful for testing theory, were identified in open-sources. The results of the case study show that open-source data are potentially as effective as official data in identifying individual- and situational-level characteristics, provide access to variables not found in official homicide data, and offer geographic data that can be used to link macro-level characteristics to homicide events. © The Author(s) 2015.

Ten percent of all homicide perpetrators are female and homicidal acts committed by women are mostly a result of interpersonal conflicts. We carried out a retrospective psychosocial analysis of ten homicide cases committed by women with an urban mid-European background. We evaluated characteristic determinants regarding 1) deed circumstances and motives, 2) the perpetrators, and 3) the victims. Results were compared with the literature on female and male homicides. Autopsy records of the Institute of Legal Medicine of the University Hospital of Düsseldorf, Germany, during the time period from 2006 to 2011 were searched for homicides committed by female perpetrators. Prosecution files were reviewed for further information. The sample comprised N = 10 female homicide perpetrators and eleven victims. The mentioned determinants of the homicide were fairly consistent. All deeds occurred in the domestic context; they were mostly unplanned. All perpetrators were socially isolated and faced socially challenging situations. Most perpetrators were of low socioeconomic status. Furthermore, all victims were helpless and/or dependent on the perpetrator. The presence of a major psychiatric disorder was uncommon and, in contrast to male perpetrators, most women had no previous convictions. The potential value of these core findings in our sample regarding prevention is discussed. Copyright © 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

To discuss and summarize the major characteristics, autopsy examination, and scene investigation in infant homicide cases. From 2008 to 2013 in Suzhou, the information of seven detected infant homicide cases were collected and analyzed. The criminal suspects were victims' mothers with young ages and pregnancies were premarital. Infant homicide cases occurred at the same location of the delivery. The infants died of mechanical asphyxia in the majority of the cases. Most bodies were naked and their umbilical cords were not cut by iatrogenic method and didn't connect with the bodies. The standardization of forensic investigation can improve the analysis and detection of infant homicide cases.

We examined the relationship between levels of household firearm ownership, as measured directly and by a proxy-the percentage of suicides committed with a firearm-and age-adjusted firearm homicide rates at the state level. We conducted a negative binomial regression analysis of panel data from the Centers for Disease Control and Prevention's Web-Based Injury Statistics Query and Reporting Systems database on gun ownership and firearm homicide rates across all 50 states during 1981 to 2010. We determined fixed effects for year, accounted for clustering within states with generalized estimating equations, and controlled for potential state-level confounders. Gun ownership was a significant predictor of firearm homicide rates (incidence rate ratio = 1.009; 95% confidence interval = 1.004, 1.014). This model indicated that for each percentage point increase in gun ownership, the firearm homicide rate increased by 0.9%. We observed a robust correlation between higher levels of gun ownership and higher firearm homicide rates. Although we could not determine causation, we found that states with higher rates of gun ownership had disproportionately large numbers of deaths from firearm-related homicides.

Homicides by older people are rare and might differ from those committed by younger people. To investigate the characteristics of older homicide offenders in New South Wales (NSW), Australia. A systematic search of legal, criminological and media databases for cases of homicide committed by people in NSW aged 55 and over, during the 18 years from 1993 to 2010. Eighty-seven cases were identified through databases. Legal documents were obtained for 70 offenders, comprising about 5% of homicides committed in NSW in the period of the study. The proportions of male offenders and rates of firearm use were similar to other age groups. Twelve of the 14 homicides using guns occurred outside the metropolitan area. Older offenders were more likely to have cognitive impairment or psychotic illness. Victims were more likely to be female and in a domestic relationship with the offender. Homicide by an older person is rare, and more commonly involves a man killing a family member. Correctional facilities will increasingly have to consider the needs of older people serving long sentences. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Objectives. We estimated the frequency and examined the characteristics of intimate partner homicide and related deaths in 16 US states participating in the National Violent Death Reporting System (NVDRS), a state-based surveillance system. Methods. We used a combination of quantitative and qualitative methods to analyze NVDRS data from 2003 to 2009. We selected deaths linked to intimate partner violence for analysis. Results. Our sample comprised 4470 persons who died in the course of 3350 intimate partner violence–related homicide incidents. Intimate partners and corollary victims represented 80% and 20% of homicide victims, respectively. Corollary homicide victims included family members, new intimate partners, friends, acquaintances, police officers, and strangers. Conclusions. Our findings, from the first multiple-state study of intimate partner homicide and corollary homicides, demonstrate that the burden of intimate partner violence extends beyond the couple involved. Systems (e.g., criminal justice, medical care, and shelters) whose representatives routinely interact with victims of intimate partner violence can help assess the potential for lethal danger, which may prevent intimate partner and corollary victims from harm.

The epidemic of deaths by homicide affects every society around the world and represents a major public health crisis. Detailed information on the characteristics of homicides victims from Islamic countries is limited. This article presents forensic epidemiological data on homicides in Isfahan, Iran, during 2013-2015. Isfahan has a population of more than 5 million and 69,387 deaths with 246 homicides between 2013 and 2015. Most victims were male (73%), between the ages of 15 to 29 years (39.5%), married (54%), and employed (54%). The relationship between the actor and the victims showed that 12% were married, 15% friends, 25% strangers, and 47% others or unknown. The most frequent method of homicides was by stabbing (45%), followed by firearms (23%), strangulation (14%), and blunt force trauma (7%). The top 3 methods among males were stabbing, firearms, and strangulation, whereas among females, it was stabbing, strangulation, and by other methods. There was no significant effect on homicide rates by month, weekday, or temperature. Investigators examining deaths in Muslin countries must understand and adjust for the culture, norms, and religious ideology.

Homicide-suicide is an event in which the murderer commits suicide after the homicide. There are at least 14 epidemiological studies on the topic, and all have found that homicide-suicide is more common among family members. The murderers are most often males and the victims females. There is no recent research on this phenomenon in Italy. The purpose of the study was to evaluate the incidence of homicide-suicide in Italy over a period of 24 yrs and to compare Italian data with published international data. We used information gathered by press agencies and from the four major Italian newspapers. Between 1985 and 2008, 662 cases of homicide-suicide were identified, with 1776 deaths. The murderer was male in 84.6% of the cases, typically using a firearm. The most common motivation was romantic jealousy, followed by socio-economic stress. The rate of homicide-suicide was 0.04%. Comparison with international studies is not always possible due to the lack of information for certain categories. The common factors identified may be helpful for prevention.

McGrath, Melissa; Oyebode, Femi

2005-07-01

An independent inquiry has been mandatory for all homicides committed by persons in contact with mental health services in England and Wales since 1994. The aim of this study is to provide a detailed description of the characteristics of the perpetrators of homicides covered by the independent inquiries between 1994 and 2002. Ninety-seven published inquiry reports were collected for analysis. Descriptive case data regarding the perpetrator was manually abstracted from each report using a structured questionnaire. Ninety-nine individuals committed 109 homicides. Most perpetrators of homicide were male, with a diagnosis of schizophrenia or other psychotic illness. Victims are most likely to be a family member or an acquaintance. Psychotic symptoms as well as alcohol or substance misuse were found to be present at the time of homicide. Comparisons with the National Confidential Inquiry into Suicides and Homicide by People with a Mental Illness suggest that independent inquiries appear to focus on high profile cases. Patient characteristics can be used to inform risk assessments that may improve current prediction of violence in mentally ill persons.

Do vehicular emissions dominate the source of C6-C8 aromatics in the megacity Shanghai of eastern China?

The characteristic ratios of volatile organic compounds (VOCs) to i-pentane, the indicator of vehicular emissions, were employed to apportion the vehicular and non-vehicular contributions to reactive species in urban Shanghai. Two kinds of tunnel experiments, one tunnel with more than 90% light duty gasoline vehicles and the other with more than 60% light duty diesel vehicles, were carried out to study the characteristic ratios of vehicle-related emissions from December 2009 to January 2010. Based on the experiments, the characteristic ratios of C6-C8 aromatics to i-pentane of vehicular emissions were 0.53 ± 0.08 (benzene), 0.70 ± 0.12 (toluene), 0.41 ± 0.09 (m,p-xylenes), 0.16 ± 0.04 (o-xylene), 0.023 ± 0.011 (styrene), and 0.15 ± 0.02 (ethylbenzene), respectively. The source apportionment results showed that around 23.3% of C6-C8 aromatics in urban Shanghai were from vehicular emissions, which meant that the non-vehicular emissions had more importance. These findings suggested that emission control of non-vehicular sources, i.e. industrial emissions, should also receive attention in addition to the control of vehicle-related emissions in Shanghai. The chemical removal of VOCs during the transport from emissions to the receptor site had a large impact on the apportionment results. Generally, the overestimation of vehicular contributions would occur when the VOC reaction rate constant with OH radicals (kOH) was larger than that of the vehicular indicator, while for species with smaller kOH than the vehicular indicator, the vehicular contribution would be underestimated by the method of characteristic ratios.

The primary purpose of this study was to present the epidemiologic review of homicide deaths certified by the Fulton County Medical Examiner's Office from January 1, 1996 through December 31, 2005 in children younger than 5 years. The secondary purpose of this study was to determine if the observed cases of homicide deaths among children younger than 5 years in Fulton County are significantly greater than expected when compared with those in the State of Georgia. For purposes of this study, only homicide deaths of Fulton County residents were included. The authors reviewed all homicide cases in children younger than 5 years: infancy (<1 year) and early childhood (1-4 years). χ values were calculated using Epi Info (version 3.4.1; Centers for Disease Control and Prevention, Atlanta, Ga) to determine differences in homicide among age group, race, and sex variables. In addition, a χ test at the α level of 0.05 was done to determine if the observed cases of homicide deaths among children younger than 5 years in Fulton County were significantly greater than expected when compared with those in the State of Georgia. There were 49 homicide cases in children younger than 5 years identified over this 10-year period. The yearly distribution of these 49 homicide deaths ranged from 1 death in 2003 to 9 deaths in 2004. Most of the patients were male (n=29, 59.2%) and black (n=44, 89.8%). Between infancy and early childhood cases, homicide victims were nearly equally divided between the 2 groups. However, χ values showed that decedents younger than 5 years are more likely to have died of homicide compared with decedents 5 years or older (odds ratio [OR], 1.74; 95% confidence interval [CI], 1.29-2.35). Black decedents younger than 5 years are more likely to have died of homicide compared with other races (OR, 3.21; 95% CI, 1.21-9.28). Male and female decedents are equally at risk to have died of homicide (OR, 1.14; 95% CI, 0.61-2.11). The authors also determined that the total homicide risk for children younger than 5 years in Fulton County during the years 1996 to 2005, at the α level of 0.05, is 1.8 relative to the state. Brain injury was the primary cause of death in most cases (n=23, 46.9%). Although this study was unable to collect information on the victim's suspect/offender characteristics, it was noted that only 37% of the cases (n=18) went to trial. Most homicide investigations were under the Atlanta police jurisdiction (n=28, 57.1%). Results from this study may assist local and state government officials in recognizing the epidemiologic characteristics of children at risk to help them allocate limited resources efficiently and implement preventive measures to at-risk populations effectively.

Misclassification of childhood homicide on death certificates.

Lapidus, G D; Gregorio, D I; Hansen, H

1990-01-01

Suspect classification of homicide deaths of Connecticut residents under 20 years of age was noted for 29 percent of cases examined. Misclassification was attributed to incomplete or erroneous information recorded on the death certificates, rather than errors in the designation of ICD-9 homicide codes. The results have important implications in the interpretation of vital statistics when homicide is listed as the cause of death and underscore the value of record linkage systems. PMID:2297072

A cross-national study of the association between natural resource rents and homicide rates, 2000-12.

PubMed

Stretesky, Paul B; Long, Michael A; Lynch, Michael J

2017-07-01

Countries that rely on natural resource rents (that is, the revenue generated from the sale of natural resources) may suffer from a variety of social problems. This exploratory study reviews the natural resource extraction literature to derive a 'natural resource rents-homicide' hypothesis. Data for 173 countries for the years 2000 to 2012 are examined to determine if there is a correlation between natural resource rents and homicide rates. Multilevel growth models suggest that natural resource rents are positively correlated with homicide rates within countries (level 1) but not between them (level 2). Importantly, the correlation between natural resource rents and homicide is strongest when natural resource rents are lagged. We conclude by suggesting that increasing natural resource rents may be counterproductive over the long run and sow the seeds for a future increase in homicide.

Blue Thursday? Homicide and suicide among urban 15-24-year-old black male Americans.

PubMed Central

Greenberg, M; Schneider, D

1992-01-01

A comparative analysis was made of day of the week variations in homicide and suicide deaths among 15-24-year-old white males, black males, white females, and black females in the 22 counties with the most black persons in the United States. Thirty-seven percent of black Americans and 14 percent of white Americans lived in these densely populated counties. The authors expected a weekend excess of homicide and a Monday excess of suicide. They found a pronounced excess of homicides on weekends, especially among white males. A slight excess of suicide was observed on Monday, but other slight excesses of suicide were also found. Young black males exhibited an unexpected excess of homicides and suicides on Thursday. On Thursdays the black male-white male ratio for homicide was 1.43 and for suicide, 1.26. Possible explanations for the young black males' blue Thursday phenomenon are offered. PMID:1594735

Spatial Heterogeneity in the Effects of Immigration and Diversity on Neighborhood Homicide Rates

PubMed Central

Graif, Corina; Sampson, Robert J.

2010-01-01

This paper examines the connection of immigration and diversity to homicide by advancing a recently developed approach to modeling spatial dynamics—geographically weighted regression. In contrast to traditional global averaging, we argue on substantive grounds that neighborhood characteristics vary in their effects across neighborhood space, a process of “spatial heterogeneity.” Much like treatment-effect heterogeneity and distinct from spatial spillover, our analysis finds considerable evidence that neighborhood characteristics in Chicago vary significantly in predicting homicide, in some cases showing countervailing effects depending on spatial location. In general, however, immigrant concentration is either unrelated or inversely related to homicide, whereas language diversity is consistently linked to lower homicide. The results shed new light on the immigration-homicide nexus and suggest the pitfalls of global averaging models that hide the reality of a highly diversified and spatially stratified metropolis.

Social welfare support and homicide: longitudinal analyses of European countries from 1994 to 2010.

PubMed

McCall, Patricia L; Brauer, Jonathan R

2014-11-01

The purpose of this research is to explore the extent to which retrenchment in welfare support is related to homicide trends across European countries between 1994 and 2010. Using a longitudinal decomposition design that allows for stronger causal inferences compared to typical cross-sectional designs, we examine these potential linkages between social support spending and homicide with data collected from a heterogeneous sample of European nations, including twenty Western nations and nine less frequently analyzed East-Central nations, during recent years in which European nations generally witnessed substantial changes in homicide rates as well as both economic prosperity and fiscal crisis. Results suggest that even incremental, short-term changes in welfare support spending are associated with short-term reductions in homicide-specifically, impacting homicide rates within two to three years for this sample of European nations.

HOMED-homicides eastern Denmark: an introduction to a forensic medical homicide database.

PubMed

Colville-Ebeling, Bonnie; Frisch, Morten; Lynnerup, Niels; Theilade, Peter

2014-11-01

An introduction to a forensic medical homicide database established at the Department of Forensic Medicine in Copenhagen. The database contains substantial clinical and demographic data obtained in conjunction with medico-legal autopsies of victims and forensic clinical examinations of perpetrators in homicide cases in eastern Denmark. The database contains information on all homicide cases investigated at the Department of Forensic Medicine in Copenhagen since 1971. Coverage for the catchment area of the department is assumed to be very good because of a medico-legal homicide autopsy rate close to 100%. Regional differences might exist however, due to the fact that the catchment area of the department is dominated by the city of Copenhagen. The strength of the database includes a long running time, near complete regional coverage and an exhaustive list of registered variables it is useful for research purposes, although specific data limitations apply. © 2014 the Nordic Societies of Public Health.

[Retrospective Analysis of 17 Family Homicide Cases].

PubMed

Xu, W J; Ji, P

2016-12-01

To summarize the characteristics of family homicide cases and to provide reference for the analysis and prevention of such cases. Seventeen solved family homicide cases in Liyang from 2004 to 2014 were investigated. The original registration information, record of scene investigation, corpse inspection report and case situation were analyzed statistically. The characteristics of the 17 family homicides cases showed that most victims were female and most suspects were male, and spouse infidelity and suspected spouse infidelity have higher proportion in the motives for the killings. Murders by patients with psychosis, camouflage murders and murder-suicides occupied a certain proportion in the family homicide cases. The family homicide cases are correlated with the family factors such as extramarital sexual intercourse and murder by patients with psychosis. Some suspects suicided after murder. The tools for committing crimes have the features of simplicity, randomness and easy source availability. Copyright© by the Editorial Department of Journal of Forensic Medicine

Autocorrelation and cross-correlation in time series of homicide and attempted homicide

NASA Astrophysics Data System (ADS)

Machado Filho, A.; da Silva, M. F.; Zebende, G. F.

2014-04-01

We propose in this paper to establish the relationship between homicides and attempted homicides by a non-stationary time-series analysis. This analysis will be carried out by Detrended Fluctuation Analysis (DFA), Detrended Cross-Correlation Analysis (DCCA), and DCCA cross-correlation coefficient, ρ(n). Through this analysis we can identify a positive cross-correlation between homicides and attempted homicides. At the same time, looked at from the point of view of autocorrelation (DFA), this analysis can be more informative depending on time scale. For short scale (days), we cannot identify auto-correlations, on the scale of weeks DFA presents anti-persistent behavior, and for long time scales (n>90 days) DFA presents a persistent behavior. Finally, the application of this new type of statistical analysis proved to be efficient and, in this sense, this paper can contribute to a more accurate descriptive statistics of crime.

Sexual Homicide by Older Male Offenders.

2017-07-01

Recent research has expanded our understanding of sexual homicide offenders (SHOs). However, little exists beyond case reports for older SHOs. We characterized male SHOs ≥ 55 years, comparing them to typical adult male SHOs who are in their 20s. Analysis of 37 years (1976-2012) of US Supplementary Homicide Reports data provided a large SHO sample (N = 3453). Three case reports provide clinical context for the diverse nature and patterns of older SHOs. Only 32 older male SHOs and no older female SHOs were identified. Murders by older SHOs accounted for only 0.5% of US sexual homicides. Unlike typical SHOs that generally target young adult females, over two-thirds of older SHO victims were ≥40 years, and one-third were ≥55 years. Sexual homicides by older SHOs, like sexual homicide in general, decreased over the study period. These crimes, while exceedingly rare, do occur, warranting special consideration. © 2017 American Academy of Forensic Sciences.

The global prevalence of intimate partner homicide: a systematic review.

2013-09-07

Homicide is an important cause of premature mortality globally, but evidence for the magnitude of homicides by intimate partners is scarce and hampered by the large amount of missing information about the victim-offender relationship. The objective of the study was to estimate global and regional prevalence of intimate partner homicide. A systematic search of five databases (Medline, Global Health, Embase, Social Policy, and Web of Science) yielded 2167 abstracts, and resulted in the inclusion of 118 full-text articles with 1122 estimates of the prevalence of intimate partner homicide after double-blind screening. All studies were included that reported the number or proportion of women or men who were murdered by an intimate partner in a country, province, or town, using an inclusive definition of an intimate partner. Additionally, a survey of official sources of 169 countries provided a further 53 estimates. We selected one estimate per country-year using a quality assessment decision algorithm. The median prevalence of intimate partner homicide was calculated by country and region overall, and for women and men separately. Data were obtained for 66 countries. Overall 13·5% (IQR 9·2-18·2) of homicides were committed by an intimate partner, and this proportion was six times higher for female homicides than for male homicides (38·6%, 30·8-45·3, vs 6·3%, 3·1-6·3). Median percentages for all (male and female) and female intimate partner homicide were highest in high-income countries (all, 14·9%, 9·2-18·2; female homicide, 41·2%, 30·8-44·5) and in southeast Asia (18·8%, 11·3-18·8; 58·8%, 58·8-58·8). Adjustments to account for unknown victim-offender relationships generally increased the prevalence, suggesting that results presented are conservative. At least one in seven homicides globally and more than a third of female homicides are perpetrated by an intimate partner. Such violence commonly represents the culmination of a long history of abuse. Strategies to reduce homicide risk include increased investment in intimate partner violence prevention, risk assessments at different points of care, support for women experiencing intimate partner violence, and control of gun ownership for people with a history of violence. Improvements in country-level data collection and monitoring systems are also essential, because data availability and quality varied strongly across regions.

Suicide and Murder-Suicide Involving Aircraft.

2016-04-01

This is a systematic review of suicide and homicide-suicide events involving aircraft. In aeromedical literature and in the media, these very different events are both described as pilot suicide, but in psychiatry they are considered separate events with distinct risk factors. Medical databases, internet search engines, and aviation safety databases were searched in a systematic way to obtain relevant cases. Relevant articles were searched for additional references. There were 65 cases of pilot suicide and 6 cases of passengers who jumped from aircraft found. There were also 18 cases of homicide-suicide found involving 732 deaths. Pilots perpetrated 13 homicide-suicide events. Compared to non-aviation samples, a large percentage of pilot suicides in this study were homicide-suicides (17%). Homicide-suicide events occur extremely rarely. However, their impact in terms of the proportion of deaths is significant when compared to deaths from accidents. There is evidence of clustering where pilot suicides occur after by media reports of suicide or homicide-suicide. Five of six homicide-suicide events by pilots of commercial airliners occurred after they were left alone in the cockpit. This, along with a sixth incident in which active intervention by a Japan Air crew saved 147 lives, suggests that having two flight members in the cockpit is potentially protective. No single factor was associated with the risk for suicide or homicide-suicide. Factors associated with both events included legal and financial crises, occupational conflict, mental illness, and relationship stressors. Drugs and/or alcohol played a role in almost half of suicides, but not in homicide-suicides.

Symptom profiles and parental bonding in homicidal versus non-violent male schizophrenia patients.

To compare the intensity and the profile of psychotic symptoms and the characteristics of parental bonding of male schizophrenia patients with a history of homicide and those without a history of violent behaviour. Clinical question - We hypothesized more intense psychotic symptoms, especially positive symptoms as signs of a more severe psychopathology in the background of homicidal behaviour. We also hypothesized a more negatively perceived pattern (less Care more Overprotection) of parental bonding in the case of homicidal schizophrenia patients than in non-violent patients and non-violent healthy controls. Symptom severity and symptom profiles were assessed with the Positive and Negative Syndrome Scale in a group of male schizophrenia patients (n=22) with the history of committed or attempted homicide, and another group (n=19) of male schizophrenia patients without a history of violent behaviour. Care- and Overprotection were assessed using the Parental Bonding Instrument (PBI) in a third group of non-violent healthy controls (n=20), too. Positive, negative and general psychopathology symptoms in the homicidal schizophrenia group were significantly (p<0.005) more severe than in the non-violent schizophrenia group. Non-violent schizophrenia patients scored lower on Care and higher on Overprotection than violent patients and healthy controls. Homicidal schizophrenia patients showed a pattern similar to the one in the healthy control group. It seems imperative to register intense positive psychotic symptoms as predictive markers for later violent behaviour. In the subgroup of male homicidal schizophrenia patients negatively experienced parental bonding does not appear to be major contributing factor to later homicidal behaviour.

Homicides - United States, 2007 and 2009.

2013-11-22

According to 1981-2009 data, homicide accounts for 16,000-26,000 deaths annually in the United States and ranks within the top four leading causes of death among U.S. residents aged 1-40 years. Homicide can have profound long-term emotional consequences on families and friends of victims and on witnesses to the violence, as well as cause excessive economic costs to residents of affected communities. For years, homicide rates have been substantially higher among certain populations. Previous reports have found that homicides are higher among males, adolescents and young adults, and certain racial/ethnic groups, such as non-Hispanic blacks, non-Hispanic American Indian/Alaska Natives (AI/ANs), and Hispanics. The 2011 CDC Health Disparities and Inequalities Report (CHDIR) described similar findings for the year 2007. For example, the 2011 report showed that the 2007 homicide rate was highest among non-Hispanic blacks (23.1 deaths per 100,000), followed by AI/ANs (7.8 deaths per 100,000), Hispanics (7.6 deaths per 100,000), non-Hispanic whites (2.7 deaths per 100,000), and Asian/Pacific Islanders (A/PIs) (2.4 deaths per 100,000). In addition, non-Hispanic black men aged 20-24 years were at greatest risk for homicide in 2007, with a rate that exceeded 100 deaths per 100,000 population. Other studies have reported that community factors such as poverty and economic inequality and individual factors such as unemployment and involvement in criminal activities can play a substantial role in these persistent disparities in homicide rates. Public health strategies are needed in communities at high risk for homicide to prevent violence and save lives.

Children bereaved by fatal intimate partner violence: A population-based study into demographics, family characteristics and homicide exposure

2017-01-01

Background In the context of violence against women, intimate partner homicide increasingly receives research and policy attention. Although the impact of losing a parent due to intimate partner homicide is intuitively obvious, little is known about the children involved. We aimed to identify all children bereaved by parental intimate partner homicide in the Netherlands in the period 2003–2012, describe their demographics and family circumstances, and assess their exposure to prior violence at home and to the homicide itself. Methods and findings We cross-examined 8 national data sources and extracted data about children’s demographics and circumstances prior to, and during the homicide. Our primary outcomes were prior violence at home (child maltreatment, neglect or domestic violence) and homicide witness status (ranging from being at a different location altogether to being present at the scene). During the decade under study, 256 children lost a biological parent due to 137 cases of intimate partner homicide. On average, the children were 7.4 years old at the time of the homicide (51.1% were boys; 95% CI 47.3–54.7) and most lost their mother (87.1%; full population data). Immigrant children were overrepresented (59.4%; 95% CI 52.8–66.0). Of the children for whom information about previous violence at home was gathered, 67.7% (95% CI 59.7–73.7) were certainly exposed and 16.7% (95% CI 11.3–22.2) probably. Of the children who had certainly been exposed, 43.1% (95% CI 41.1–60.9) had not received social services or mental health care. The majority of the children (58.7%; 95% CI 52.1–65.3) were present at the location of the homicide when the killing took place, with varying levels of exposure. Homicide weapons mostly involved cutting weapons and firearms, leading to graphic crime scenes. Conclusions Care providers need capacity not only to help children cope with the sudden loss of a parent but also with unaddressed histories of domestic violence and exposure to graphic homicide scenes, in a culture-sensitive way. Future directions include longitudinal monitoring of children’s mental health outcomes and replication in other countries. PMID:28976977

Filicide in offspring of parents with severe psychiatric disorders: a population-based cohort study of child homicide.

Although rare in absolute terms, risk of homicide is markedly elevated among children of parents with mental disorders. Our aims were to examine risk of child homicide if 1 or both parents had a psychiatric history, to compare effects by parental sex and diagnostic group, and to assess likelihood of child homicide being perpetrated by parents according to their psychiatric history. A prospective, register-based cohort study using the entire Danish population born between January 1, 1973, and January 1, 2007, was conducted. Follow-up of the cohort members began on their date of birth and ended on January 1, 2007; their 18th birthday; their date of death; or their date of emigration, whichever came first. We used the Danish national registers from 1973 to 2007 to study homicide risk between children whose parents were previously admitted to a psychiatric hospital, including diagnosis-specific analyses, versus their unexposed counterparts. In addition, we used police records during 2000 to 2005 to examine whether or not 1 of the parents was the perpetrator. Rates of homicide were analyzed using survival analysis. Children of parents previously admitted to a psychiatric hospital had an overall higher risk of being homicide victims (MRR = 8.94; 95% CI, 6.56-12.18). The risk differed according to parental sex and psychiatric diagnosis (ICD-8 and ICD-10 criteria). The absolute risk of homicide was 0.009% if neither parent had been admitted before the birth of their child and 0.051% if 1 of the parents had previously been admitted. During 2000 to 2005, 88% of the child homicide cases were filicide victims. This percentage was not significantly different for parents with a previous psychiatric admission versus those without such a history. In the large majority of Danish child-homicide cases, a parent was the perpetrator, regardless of whether there had been parental admission to a psychiatric hospital. Children of parents previously admitted had a higher risk of being homicide victims, and risks were especially high in young children whose mothers were hospitalized with affective disorders or schizophrenia. However, the relative risks presented in the current study are based on extremely rare events, and the overwhelming majority of children whose parents have a psychiatric history do not become homicide victims. © Copyright 2011 Physicians Postgraduate Press, Inc.

Are Competitive Materialism and Female Employment Related to International Homicide Rate?

PubMed

Chon, Don Soo

2017-04-01

The institutional anomie theory is a proposal that states competitive materialism, an intense cultural pressure for economic success at any costs, and increased female employment may be related to a high homicide rate. The current work tested this proposition by utilizing homicide data collected from 45 developed and developing countries. Regression results did not support the proposition. Competitive materialism and female employment were not significantly related to the cross-national variation of homicide rates.

Adverse newspaper reporting of mental illness and in particular, violence committed by a mentally ill person, is thought to contribute to stigma. However, violent events are also considered highly newsworthy by journalists. The aim of this study was to compare the likelihood of newspaper reporting for convicted perpetrators of homicide with and without a history of contact with mental health services. A 12 month (April 2000-March 2001) cohort of 577 homicide perpetrators with and without a history of contact with mental health services in England and Wales was examined. These cases were identified by the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness. By examining 12 national newspapers, we compared the likelihood of reporting homicide perpetrators with and without mental illness. Under half (228 cases, 40%) of the homicide perpetrators were reported in at least one of the study newspapers. Under a fifth (94 cases, 16%) of perpetrators had a history of contact with mental health services and such previous contact did not increase the likelihood of newspaper reporting (odds ratio 1.0 (0.6-1.6)). Previous contact with mental health services did not influence the newsworthiness of a homicide perpetrator. The stigmatizing effect of reporting homicide by perpetrators with mental illness may relate more to the quality of reporting rather than selective over-reporting.

Neighborhood Racial/Ethnic Concentration, Social Disadvantage, and Homicide Risk: An Ecological Analysis of 10 U.S. Cities

PubMed Central

Wall, Melanie

2008-01-01

Homicide is one of the leading causes of death among African-American and Hispanic men. We investigated how neighborhood characteristics associated with social disadvantage explain racial/ethnic homicide gaps in 10 U.S. cities. The test hypotheses were that (1) higher concentrations of African-Americans and Hispanics would be associated with higher homicide rates and (2) the relationship between racial/ethnic concentration and homicide would be attenuated after adjusting for neighborhood characteristics (e.g., unemployment, median household income, low educational attainment, and female headship). The test hypotheses were examined using separate Poisson regression models, which adjusted for spatial autocorrelation. Homicide rates were greater in neighborhoods with higher concentrations of African-Americans and Hispanics than in other groups, and the association of neighborhood racial/ethnic concentration with homicide was reduced after adjusting for neighborhood social disadvantage variables, especially percent female head of household and percent persons with less than a high school education. We also found that the relationship between neighborhood racial/ethnic concentration and homicide was explained more by social disadvantage variables in some cities than in others. Based on our findings, policy makers may wish to consider implementation of policies that (1) expand early childhood education programs and higher education opportunities and (2) encourage economic and community development initiatives in socially disadvantaged neighborhoods.

Firearm homicide is a leading cause of injury death in the United States, and there is considerable debate over the effectiveness of firearm policies. An analysis of the effectiveness of firearm laws on firearm homicide is important to understand optimal policies to decrease firearm homicide in the United States. To evaluate the association between firearm laws and preventing firearm homicides in the United States. We evaluated peer-reviewed articles from 1970 to 2016 focusing on the association between US firearm laws and firearm homicide. We searched PubMed, CINAHL, Lexis/Nexis, Sociological Abstracts, Academic Search Premier, the Index to Legal Periodicals and Books, and the references from the assembled articles. We divided laws into 5 categories: those that (1) curb gun trafficking, (2) strengthen background checks, (3) improve child safety, (4) ban military-style assault weapons, and (5) restrict firearms in public places and leniency in firearm carrying. The articles were assessed using the standardized Guide to Community Preventive Services data collection instrument and 5 additional quality metrics: (1) appropriate data source(s) and outcome measure(s) were used for the study, (2) the time frame studied was adequate, (3) appropriate statistical tests were used, (4) the analytic results were robust, and (5) the disaggregated results of control variables were consistent with the literature. In the aggregate, stronger gun policies were associated with decreased rates of firearm homicide, even after adjusting for demographic and sociologic factors. Laws that strengthen background checks and permit-to-purchase seemed to decrease firearm homicide rates. Specific laws directed at firearm trafficking, improving child safety, or the banning of military-style assault weapons were not associated with changes in firearm homicide rates. The evidence for laws restricting guns in public places and leniency in gun carrying was mixed. The strength of firearm legislation in general, and laws related to strengthening background checks and permit-to-purchase in particular, is associated with decreased firearm homicide rates. High-quality research is important to further evaluate the effectiveness of these laws. Legislation is just 1 part of a multipronged approach that will be necessary to decrease firearm homicides in the United States.

Background After a 1996 firearm massacre in Tasmania in which 35 people died, Australian governments united to remove semi‐automatic and pump‐action shotguns and rifles from civilian possession, as a key component of gun law reforms. Objective To determine whether Australia's 1996 major gun law reforms were associated with changes in rates of mass firearm homicides, total firearm deaths, firearm homicides and firearm suicides, and whether there were any apparent method substitution effects for total homicides and suicides. Design Observational study using official statistics. Negative binomial regression analysis of changes in firearm death rates and comparison of trends in pre–post gun law reform firearm‐related mass killings. Setting Australia, 1979–2003. Main outcome measures Changes in trends of total firearm death rates, mass fatal shooting incidents, rates of firearm homicide, suicide and unintentional firearm deaths, and of total homicides and suicides per 100 000 population. Results In the 18 years before the gun law reforms, there were 13 mass shootings in Australia, and none in the 10.5 years afterwards. Declines in firearm‐related deaths before the law reforms accelerated after the reforms for total firearm deaths (p = 0.04), firearm suicides (p = 0.007) and firearm homicides (p = 0.15), but not for the smallest category of unintentional firearm deaths, which increased. No evidence of substitution effect for suicides or homicides was observed. The rates per 100 000 of total firearm deaths, firearm homicides and firearm suicides all at least doubled their existing rates of decline after the revised gun laws. Conclusions Australia's 1996 gun law reforms were followed by more than a decade free of fatal mass shootings, and accelerated declines in firearm deaths, particularly suicides. Total homicide rates followed the same pattern. Removing large numbers of rapid‐firing firearms from civilians may be an effective way of reducing mass shootings, firearm homicides and firearm suicides. PMID:17170183

Reliable epidemiological data on sexual homicide are sparse, especially on trends in its incidence over time and age at arrest. Our main aims were to study age at arrest and incidence trends for sexual homicide in the USA over about three decades (1976-2007). We conducted longitudinal analyses of data from the largest USA homicide database available for the years 1976-2007. The mean age at arrest for a sexual homicide was 26.3 years (range 7-76; modal 21 years). Three quarters of these offenders were young adults aged 18-35. Age at probable first arrest for a sexual homicide rose significantly from a mean of 25 to a mean of 29 years over the study period. The last decade of the three studied accounted for just one quarter of the homicides as charged in the whole period, but the proportion of sexual homicides specifically fell with each decade, so that the first period accounted for 56% of those in the whole period, the second for 33% and the final decade for just 11%. This was reflected in a reduction in the proportion of all homicides that were sexual, from 1.4% in the first decade to 0.8% in the second and 0.4% in the third, declining by a factor of five for adults and seven for juveniles. Use of official national criminal statistics has limitations in studying the epidemiology of any particular behaviour. Nonetheless, our findings of falling sexual homicide rates and of changes in at least one important demographic of these killers indicate a need for a considered reappraisal of such crimes. Establishment of accurate epidemiology and a study of associated factors may assist in the improvement of investigative and preventive strategies. Copyright © 2014 John Wiley & Sons, Ltd.

Homicide, an external cause of morbidity and mortality, caused 473,000 deaths worldwide in 2012, a rate of 6.2 per 100,000 inhabitants. The aim of this study was to describe homicide mortality trends in Chile between 2000 and 2012 by year, gender, age group, geographic distribution (by zone and by region) and type of homicide. This was a population-based study. Data for homicide mortality in Chile between 2000 and 2012 were used and they were provided by the Chilean Ministry of Health's Department of Statistics and Health Information (DEIS) and PAHO/WHO. The homicide mortality rates were calculated per 100,000 inhabitants. The study variables were year, geographic distribution, gender, age group and type of homicide. The annual percentage change (APC) of the rates was analyzed, and a logarithm of the rates by year and region was fitted by applying linear regression models. In addition, relative risks (RR) were calculated. 95% confidence intervals were considered in all the analyses. The average yearly rate of homicide (HMR) in Chile (2000-2012) was 4.9. The rates were higher in men (8.7) than in women (1.1), with a RR of 8.2. The rates were higher in the country's central zone (5.0), increasing in recent years in the southern zone, with a significant positive APC of 1.1%. The Aisén Region had the highest rate (7.6), although Antofagasta was the region with the most significant APC (3.1%). The highest rate (9.2) was verified in the 25 to 39 age group. The highest rate (5.5) was recorded in 2005. The most frequent type of homicide was assault with an object (44.8%). Although the homicide rates are higher in the southern zone of the country, the northern zone is showing a tendency to increase, becoming an even more serious problem, which not only affects those directly involved, but society as a whole.

The objectives of this study are to determine the cause of death and based on the wounds, to analyze the different epidemiological variables on homicide in Dakar. Included were all homicides cases where an autopsy was performed and these results recorded in the autopsy register. The data collected in our work included, identity, sex, age, place of crime (location), the cause of death (the causative agent and the anatomical region injured) and the mechanism of death (the pathophysiological phenomenon causing death). On average 56 cases of homicide a year are reported, ranging from 44 cases in 2005 to 80 cases in 1999. Extrapolated to the population of Dakar this corresponds to 1.9 homicides per 100,000 inhabitants. Victims aged over 55 years represented only 4.03% of all victims. 6.52% of cases were infanticide. The crimes mainly took place in the suburbs of Dakar (51.42% of cases). Hand held weapons were used in 578 cases (89.7%) followed by firearms in 44 cases (6.8%). The study of the age of the victims has some interesting points. The homicide of elderly people in Senegal was relatively low in contrast to what is found in a developed country. The youthfulness of our population also explains the large number of homicide victims between 21 and 25. Infanticide is a particular problem in Senegal. In our study, 50.6% of homicides were found in the suburbs of Dakar followed by the peripheral area which accounted for 29.3% of homicides. The incidence of homicide can be directly correlated with the level of economic development. This frequency is much higher where incomes are low and particularly affect young males. The study of this phenomenon should lead to better prevention. The victim-type in Dakar is a young man, aged 20-25 years, killed by an instrument with an injury to the skull, neck, heart or main arteries, causing bleeding and death.

The incidence of suicide and homicide is on the increase worldwide, including India. One million people die annually due to suicides and homicides alone. Thus this study had been undertaken to find out the material and social causes of burn and to assess the socio-demographic characteristics between suicide and homicide. This retrospective study was carried out on 1393 fatal burn cases (2008-2012) who were autopsied at the mortuary of King George's Medical University, Lucknow, India. Data retrieved include: age, sex, type of family, marital status, place of incidence, psychological status and burn size (TBSA). The results were presented in Mean ± SD and percentages and analyzed with SPSS 16.0. Out of the total 1369 cases of burns, 536 cases (38.5%) were homicidal deaths in comparison to 857 cases (61.5%) of suicidal deaths. Female predominance was seen in both suicidal and homicidal deaths with peak age 30-39 years in suicides in contrast to 40-49 years in homicides. At younger age ≤19 years, the victims of suicide is almost similar to the victims of homicide; but at extremes of ages below 10 years and above 60 years, homicides were relatively more common than suicides. Married victims were predominant in the homicidal group (66.6%). There is no quite difference at the place where burn occurs. Depression and anxiety disorders were the most frequent psychiatric co-morbidities associated with suicidal behaviours. Patients from suicidal group suffered significantly larger burns than from homicidal group. Hence, this study was planned with a purpose to know the magnitude and the socio-cultural factors of the problem of burns to more clearly understand the dynamics surrounding these deaths, so that a sound prevention programme could be suggested, planned and implemented for reducing the incidence of fatal burns.

Ross, Craig S.

2013-01-01

Objectives. We examined the relationship between levels of household firearm ownership, as measured directly and by a proxy—the percentage of suicides committed with a firearm—and age-adjusted firearm homicide rates at the state level. Methods. We conducted a negative binomial regression analysis of panel data from the Centers for Disease Control and Prevention’s Web-Based Injury Statistics Query and Reporting Systems database on gun ownership and firearm homicide rates across all 50 states during 1981 to 2010. We determined fixed effects for year, accounted for clustering within states with generalized estimating equations, and controlled for potential state-level confounders. Results. Gun ownership was a significant predictor of firearm homicide rates (incidence rate ratio = 1.009; 95% confidence interval = 1.004, 1.014). This model indicated that for each percentage point increase in gun ownership, the firearm homicide rate increased by 0.9%. Conclusions. We observed a robust correlation between higher levels of gun ownership and higher firearm homicide rates. Although we could not determine causation, we found that states with higher rates of gun ownership had disproportionately large numbers of deaths from firearm-related homicides. PMID:24028252

Exploring the interrelationship between alexithymia, defense style, emotional suppression, homicide-related posttraumatic stress disorder and psychiatric co-morbidity.

This study investigated the interrelationship between alexithymia, defense style, emotional suppression, posttraumatic stress disorder (PTSD) following homicide and psychiatric co-morbidity. One hundred and fifty male homicide perpetrators and 156 male perpetrators of non-violent crime completed the Posttraumatic Stress Diagnostic Scale (except for non-violent perpetrators), the General Health Questionnaire-28, the Defense Styles Questionnaire, the Courtauld Emotional Control Scale and the Toronto Alexithymia Scale-20. The results showed that 44% of homicide perpetrators met the criteria for PTSD. No significant differences were found between groups in alexithymia, defense style and psychiatric co-morbidity. Homicide perpetrators suppressed depression significantly more than the non-violent group. PLS analyses showed that alexithymia was significantly correlated with defense style. Defense styles were significantly correlated with emotional suppression which, in turn, was associated with homicide-related PTSD and psychiatric co-morbidity. To conclude, perpetrators can experience PTSD reactions following the act of homicide. The severity of these reactions and other psychological problems were related to difficulty getting in touch with distressing emotions, the defenses they used to protect themselves psychologically and the way they suppressed their emotion.

2018-06-01

Intimate partner homicide (IPH) is a critical public health and safety issue in the USA. In this study, we determine the prevalence and correlates of perpetrator suicide and additional homicides following intimate partner homicide (IPH) in a large, diverse state with high quality data. We extract IPHs from the North Carolina Violent Death Reporting System for 2004-2013 and identify suicides and other homicides that were part of the same incidents. We analyze the likelihood (in odds ration form) of perpetrator suicide and additional homicides using logistic regression analysis. Almost all IPH-suicide cases were by men with guns (86.6%). Almost one-half of IPHs committed by men with guns ended with suicide. Male-perpetrated IPH incidents averaged 1.58 deaths if a gun was used, and 1.14 deaths otherwise. It is well-known that gun access increases the chance that a violent domestic relationship will end in death. The current findings demonstrate that gun IPH is often coupled with additional killings. As suicidal batterers will not be deterred from IPH by threat of punishment, the results underline the importance of preemption by limiting batterers' access to guns.

Abandonment and reconciliation: addressing political and common law objections to fetal homicide laws.

PubMed

Curran, Douglas S

2009-03-01

Fetal homicide laws criminalize killing a fetus largely to the same extent as killing any other human being. Historically, the common law did not generally recognize feticide as a crime, but this was because of the evidentiary "born-alive" rule, not because of the substantive understanding of the term "human being." As medicine and science have advanced, states have become increasingly willing to abandon this evidentiary rule and to criminalize feticide as homicide. Although most states have recognized the crime of fetal homicide, fourteen have not. This is largely the result of two independent obstacles: (judicial) adherence to the born-alive rule and (legislative) concern that fetal homicide laws could erode constitutionally protected reproductive rights. This Note explores a variety of fetal homicide laws that states have adopted, demonstrating that popular opinion has shifted toward recognizing this crime. It then directly confronts the objections that have prevented other states from adopting such laws: it first reviews the literature suggesting that the born-alive rule should be abandoned, as it is an obsolete evidentiary standard; it then argues that constitutionally protected reproductive liberties can be reconciled with, and in fact augmented by, punishing the killing of a fetus as a homicide.

Unequal burdens of loss: examining the frequency and timing of homicide deaths experienced by young Black men across the life course.

Smith, Jocelyn R

2015-07-01

I examined the frequency and developmental timing of traumatic loss resulting from the health disparity of homicide among young Black men in Baltimore, Maryland. Using a modified grounded theory approach, I conducted in-depth semistructured interviews with 40 Black men (aged 18-24 years) from January 2012 to June 2013. I also constructed adapted life history calendar tools using chronologies of loss, and (1) provided a comprehensive history of loss, (2) determined a specific frequency of homicide deaths, (3) indicated participants' relationship to the decedents, and (4) identified the developmental timing of deaths. On average, participants knew 3 homicide victims who were overwhelmingly peers. Participant experiences of homicide death started in early childhood, peaked in adolescence, and persisted into emerging adulthood. The traumatic loss of peer homicide was a significant developmental turning point and disrupted participants' social networks. The traumatic loss of peer homicide was a prevalent life course experience for young Black men and identified the need for trauma- and grief-informed interventions. Future research is needed to examine the physical and psychosocial consequences, coping resources and strategies, and developmental implications of traumatic loss for young Black men in urban contexts.

Homicide-suicides are rare but catastrophic events. This study examined the epidemiology of homicide-suicide in Switzerland. The study identified homicide-suicide events 1991-2008 in persons from the same household in the Swiss National Cohort, which links census and mortality records. The analysis examined the association of the risk of dying in a homicide-suicide event with socio-demographic variables, measured at the individual-level, household composition variables and area-level variables. Proportional hazards regression models were calculated for male perpetrators and female victims. Results are presented as age-adjusted hazard ratios (HR) with 95% confidence intervals (95%CI). The study identified 158 deaths from homicide-suicide events, including 85 murder victims (62 women, 4 men, 19 children and adolescents) and 68 male and 5 female perpetrators. The incidence was 3 events per million households and year. Firearms were the most prominent method for both homicides and suicides. The risk of perpetrating homicide-suicide was higher in divorced than in married men (HR 3.64; 95%CI 1.56-8.49), in foreigners without permanent residency compared to Swiss citizens (HR 3.95; 1.52-10.2), higher in men without religious affiliations than in Catholics (HR 2.23; 1.14-4.36) and higher in crowded households (HR 4.85; 1.72-13.6 comparing ≥2 with <1 persons/room). There was no association with education, occupation or nationality, the number of children, the language region or degree of urbanicity. Associations were similar for female victims. This national longitudinal study shows that living conditions associated with psychological stress and lower levels of social support are associated with homicide-suicide events in Switzerland.

Homicide, suicide, and unintentional firearm fatality: comparing the United States with other high-income countries, 2003.

Violent death is a major public health problem in the United States and throughout the world. A cross-sectional analysis of the World Health Organization Mortality Database analyzes homicides and suicides (both disaggregated as firearm related and non-firearm related) and unintentional and undetermined firearm deaths from 23 populous high-income Organization for Economic Co-Operation and Development countries that provided data to the World Health Organization for 2003. The US homicide rates were 6.9 times higher than rates in the other high-income countries, driven by firearm homicide rates that were 19.5 times higher. For 15-year olds to 24-year olds, firearm homicide rates in the United States were 42.7 times higher than in the other countries. For US males, firearm homicide rates were 22.0 times higher, and for US females, firearm homicide rates were 11.4 times higher. The US firearm suicide rates were 5.8 times higher than in the other countries, though overall suicide rates were 30% lower. The US unintentional firearm deaths were 5.2 times higher than in the other countries. Among these 23 countries, 80% of all firearm deaths occurred in the United States, 86% of women killed by firearms were US women, and 87% of all children aged 0 to 14 killed by firearms were US children. The United States has far higher rates of firearm deaths-firearm homicides, firearm suicides, and unintentional firearm deaths compared with other high-income countries. The US overall suicide rate is not out of line with these countries, but the United States is an outlier in terms of our overall homicide rate.

Homicide law reform: Coke v Bumble - revisited and reassessed.

Hodgkinson, Sarah; Prins, Herschel

2011-10-01

This contribution is a sequel to an earlier paper in the journal by the second author. It examines the Government's remit to the Law Commission to suggest revision to the law relating to homicide, and the eventual somewhat muted implementation in the Coroners and Justice Act of 2009. These changes to the law of homicide, and more specifically the revisions to the partial defences of diminished responsibility and provocation, are critically reviewed, and are discussed in light of the future of homicide law reform. It is argued that more radical reform to the substantive law of homicide is needed, but this article also discusses the problems of implementing this more radical reform given the Government's reluctance to remove the mandatory life sentence for murder.

Governance and Regional Variation of Homicide Rates: Evidence From Cross-National Data.

PubMed

Cao, Liqun; Zhang, Yan

2017-01-01

Criminological theories of cross-national studies of homicide have underestimated the effects of quality governance of liberal democracy and region. Data sets from several sources are combined and a comprehensive model of homicide is proposed. Results of the spatial regression model, which controls for the effect of spatial autocorrelation, show that quality governance, human development, economic inequality, and ethnic heterogeneity are statistically significant in predicting homicide. In addition, regions of Latin America and non-Muslim Sub-Saharan Africa have significantly higher rates of homicides ceteris paribus while the effects of East Asian countries and Islamic societies are not statistically significant. These findings are consistent with the expectation of the new modernization and regional theories. © The Author(s) 2015.

Investigate the spatial distribution pattern of the homicide rate and its relation to sociodemographic features in the Benito Juárez, Coyoacán, and Cuauhtémoc districts of Mexico City in 2010. Inferential cross-sectional study that uses spatial analysis methods to study the spatial association of the homicide rate and demographic features. Spatial association was determined through the location quotient, multiple regression analysis, and the use of geographically weighted regression. Homicides show a heterogeneous location pattern with high rates in areas with non-residential land use, low population density, and low marginalization. Spatial analysis tools are powerful instruments for the design of prevention- and recreation-focused public safety policies that aim to reduce mortality from external causes such as homicides.

This study investigated age, sex, and race/ethnicity risk patterns for homicide based on 246 children (newborn to 14 years old) who were murdered in the city of Los Angeles 1980 through 1989. Rates of homicide are higher for newborn to 4-year-olds than for 5- to 14-year-olds. Boys and girls have similar rates of homicide at young ages; among 5- to 14-year-olds, however, boys have higher rates. Characteristics of the victim, suspect, and event were fairly consistent across victim race/ethnicity. Rates vary by the victim's race/ethnicity; paralleling patterns among adults, rates of homicide are lowest for non-Hispanic White, higher for Hispanic, and highest for Black children. PMID:8484456

Homicide in the Canadian Prairies: elderly and nonelderly killings.

Ahmed, A G; Menzies, Robin P D

2002-11-01

To examine the psychosocial and clinical characteristics of male perpetrators of elderly and nonelderly homicides in the Canadian Prairies. We examined data drawn from a study of 901 adult homicide offenders who were incarcerated or on parole between 1988 and 1992 in Alberta, Saskatchewan, and Manitoba. Of those studied, 67 men were convicted of homicide involving 79 elderly victims, and 671 were convicted of homicide involving 675 nonelderly victims. Most perpetrators were single and engaged in irregular patterns of employment at the time of their index offence. Fourteen (20.8%) offenders with elderly victims had a history of psychiatric treatment, compared with 98 (14.6%) offenders with nonelderly victims; however, this difference was not statistically significant. Approximately 30% of both groups were diagnosed with personality disorders. A comparison of the index- offence characteristics showed no significant differences between the 2 groups. Our findings suggest that elderly individuals are more likely to be killed in their own homes by strangers. Social isolation appears to be a significant risk factor in cases of elderly homicide.

Homicide offenders 32 years later - a Swedish population-based study on recidivism.

2014-02-01

The literature on recidivism by homicide offenders is scarce despite its importance for individuals and for society. To establish the rate of seriously violent re-offending among homicide offenders and identify risk factors for such recidivism. A 1970s incident cohort of all homicide offenders, sane and insane, from two regions of Sweden (N = 153) was followed up until 2007 using data from the national crime register. Ten per cent of the cohort (n = 15) re-offended. The mean time from index offence to recidivism was 9.4 years. Five people (3%) committed a further homicide, and it was established that another five (3%) offenders had killed before the index offence. Prospective risk factors for violent recidivism were young age, psychotic disorder, male victim, acquainted victim and intoxicated victim. The prevalence of repeated homicide is higher than previously reported. Victim variables and mental disorder in conjunction with substance abuse appear to be two domains of particular significance for recidivism. Copyright © 2013 John Wiley & Sons, Ltd.

Aim Assess the impact of heavy drinking on homicide and suicide mortality in Russia between 1956 and 2002. Measures and design Alcohol-related mortality was used as a proxy for heavy drinking. We used autoregressive integrated moving average techniques to model total and sex-specific alcohol—homicide and alcohol—suicide relationships at the population level. Findings We found a positive and significant contemporaneous association between alcohol and homicide and between alcohol and suicide. We found no evidence of lagged relationships. These results held for overall and sex-specific associations. Conclusion Our results lend convergent validity to the alcohol—suicide link in Russia found by Nemtsov and to the alcohol—homicide associations found in cross-sectional analyses of Russia. Levels of alcohol consumption, homicide and suicide in Russia are among the highest in the world, and the mounting evidence of the damaging effects of consumption on the social fabric of the country reveals the need for intervention at multiple levels.

To provide references for forensic analysis of family homicides cases by analyzing the situations of scene, injuries and individual which were related to the family homicide cases in a county. The data of 23 family homicide cases from 2004 to 2013 were collected. The basic situation of individual involved, the relationship between dead and suspect, the cause of death, the motive, the location, time and tools of the crime and the behavior of the suspect after crime etc. were analyzed. The characteristics of the 23 family homicides cases showed that couple relationship was the most common relationship; passion killing was the most common motive; local materials were mostly used as the tools for committing crimes; most crimes were committed in residences; most time of crime was night. The analysis of family homicide cases should be based on the scene investigation, the examination of the body and combined with the investigation of the situation.

2014-07-01

Research has reported that a strong risk factor for traumatic injury is having a previous injury (i.e., recidivism). To date, the only study examining the relationship between recidivism and homicide reported strong associations, but was limited by possible selection bias. The current matched case-control study utilized coroner's data from 2004 to 2008. Subjects were linked to trauma registry data to determine whether the person had a previous traumatic injury. Conditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the association between homicide and recidivism. Homicide risk was increased for those having a previous traumatic injury (OR 1.81, 95% CI 1.09-2.99) or a previous intentional injury (OR 2.53, 95% CI 1.24-5.17). These results suggest an association between homicide and injury recidivism, and that trauma centers may be an effective setting for screening individuals for secondary prevention efforts of homicide through violence prevention programs. © 2014 American Academy of Forensic Sciences.

A Thematic Analysis of the Motivation Behind Sexual Homicide From the Perspective of the Killer.

PubMed

Kerr, Kevin J; Beech, Anthony R

2016-12-01

Using thematic analysis, this study explores the motivation to commit sexual homicide from the perspective of the perpetrator. In the process, it revisits motivational models and offender typologies that have been put forward to explain such offenses. From the homicide narratives of eight sexual homicide offenders detained in a high security hospital in the United Kingdom, four themes were found which appeared significant in terms of understanding the offenses committed. These themes were labeled as follows: (a) avenging sexual abuse, (b) events leading to a catathymic reaction, (c) homicidal impulse, and (d) emotional loneliness. Although these findings are not inconsistent with previous research, we argue that the current literature fails to capture the complexity associated with these offenses. We also argue that the context or situation in which sexual homicide occurs is a crucial feature of the offense, and one which has not been adequately taken into account by motivational models. © The Author(s) 2015.

This retrospective study examined homicides in two French departments located in the West of France (Indre-et-Loire and Loir-et-Cher) for a four-year period from 2000 to 2003. During this period 63 homicidal deaths were investigated at the Institute of Forensic Science of Tours (Indre-et-Loire). There were 45 male and 18 female victims with an average homicide rate of 1.55 per 100,000 persons. The mean age of the victims was 42 years-old. Forty-five assailants were identified; their mean age was 38 years-old. The most common method of homicide was the use of firearms (40% of the cases), followed by blunt-force injury (36%) and sharp-force injury (16%). 51% of the victims knew their assailant, a family member in 26% of the cases. Spousal homicides occurred in 16% of the cases. Dyadic death occurred in six cases. A review of the literature compares these findings to other populations.

This article describes the homicide pattern in Penang Island, Malaysia over a three-year period (2007-2009). 65 homicide autopsies were performed at the Department of Forensic Medicine, Penang Hospital over the study period. The homicide rates ranged from 0.01 to 0.09/1000 population, the highest being in the Indian ethnic group. The majority (37%) of victims were in the 20-39 years age group. The male: female ratio was 3:1. The majority of deaths were caused by blunt instruments (46%), followed by stab/slash wounds (25%) and asphyxiation (12%). 63% of homicides occurred in areas served by the police stations at Jalan Patani (23.1%), Sg. Nibong (16.9%), Central (12.3%) and Bayan Lepas (10.9%). 56 (86%) victims were brought in dead to the hospital, while 9 (14%) died after admission. Most (39%) incidences occurred in the morning. The methods of homicide were different from Kuala Lumpur, another highly urbanised area of Malaysia.

Throat cuts could be of homicidal, suicidal or accidental origin. In the cases of death from cut throat, suicide can be distinguished from homicide based on the type and location of the wound and crime scene investigation. The purpose of the current study is to attract attention to the instructive findings for origin determination in deaths by cut throat according to the number and characteristics of the wounds and crime scene investigation. We have reviewed the files of autopsies performed between the years of 2000 and 2010, and compared with previously published case reports; all results were summarized in the current study. The results showed that 60% of cases were male, 40% were female, with 27.9 years of average age. The mean number of wounds was calculated to be 34.3 per case for honor homicides, 7.4 per case for other homicides, and 2.0 per case for suicides. Numbers of wounds were approximately 5 times higher in the honor homicides compared to other homicides. If the number of wounds were excessive, possibility of honor killings should be taken into account. When the killer was a parent not in psychosis, hesitation cuts were detected. Additional lesions were present in 46.7% of the cases, and they were assessed as homicide. Presence of vertebral notch and spinal cord cuts, which require a substantial amount of force and pressure via sharp tools, indicates homicide.

Forecasting Organized Crime Homicides: Risk Terrain Modeling of Camorra Violence in Naples, Italy.

Mafia homicides are usually committed for retaliation, economic profit, or rivalry among groups. The variety of possible reasons suggests the inefficacy of a preventive approach. However, like most violent crimes, mafia homicides concentrate in space due to place-specific social and environmental features. Starting from the existing literature, this study applies the Risk Terrain Modeling approach to forecast the Camorra homicides in Naples, Italy. This approach is based on the identification and evaluation of the underlying risk factors able to affect the risk of a homicide. This information is then used to predict the most likely location of future events. The findings of this study demonstrate that past homicides, drug dealing, confiscated assets, and rivalries among groups make it possible to predict up to 85% of 2012 mafia homicides, identifying 11% of city areas at highest risk. By contrast, variables controlling for the socio-economic conditions of areas are not significantly related to the risk of homicide. Moreover, this study shows that, even in a restricted space, the same risk factors may combine in different ways, giving rise to areas of equal risk but requiring targeted remedies. These results provide an effective basis for short- and long-term targeted policing strategies against organized crime- and gang-related violence. A similar approach may also provide practitioners, policy makers, and local administrators in other countries with significant support in understanding and counteracting also other forms of violent behavior by gangs or organized crime groups.

The effect of poverty and social protection on national homicide rates: Direct and moderating effects.

PubMed

Rogers, Meghan L; Pridemore, William Alex

2013-05-01

Social protection is the ability of a government to insulate its citizens from the problems associated with poverty and market forces that negatively affect their quality of life. Prior research shows that government policies that provide social protection moderate the influence of inequality on national homicide rates. Recent research, however, reveals a strong association between poverty and national homicide rates. Further, theory and evidence suggest that social protection policies are meant to aid in providing a subsistence level of living, and thus to alleviate the vagaries of poverty not inequality. To this point, however, no studies have examined the potentially moderating effect of social protection on the strength of the association between poverty and homicide rates cross-nationally. We do so in the present study. Employing data for the year 2004 from a sample of 30 nations, we estimate a series of weighted least squares regression models to test three hypotheses: the association between poverty and homicide will remain significant and positive when controlling for social protection, social protection will have a significant negative direct effect on national homicide rates, and social protection will diminish the strength of the poverty-homicide association. The results provided evidence supporting all three hypotheses. We situate our findings in the cross-national empirical literature on social structure and homicide and discuss our results in the theoretical context of social protection.

Vandevoorde, J; Estano, N; Painset, G

Suicide-homicide could be defined as a "suicidal" behaviour, which also includes the death of at least one other individual and sometimes up to hundreds. This literature review intends to highlight some characteristic features that might be found amongst the various types of suicide-homicide. It is a complex phenomenon which can occur in different situations, from a familial and somehow intimate setting (filicide, uxoricide, marital homicide…) to a public one (workplace shooting, school shooting), including a wide range of victims, from a single victim in marital cases of suicide-homicide to hundreds of victims in certain types, such as suicide by aircraft or warrior-like multi-homicids in terrorist acts. This literature review offers a combination of data emanating from scientific publications and case studies from our practices in an attempt to insulate some common factors. A thorough examination of the offenses unravels complex processes, ideations, M.O and peculiar cognitive impairments in which the familial suicide-homicide could be rooted. Mass murders might be caused also by a psychopathological alloy, made of Grandiose Self and sub-depressive and even paranoid ideations. Concerning the terrorism and multi-homicide-suicide, this is far more complex phenomenon and is defined by a group-process enrolment and ideological conviction. Beyond epidemiological studies, both descriptive and statistical, this paper's objective is to isolate a hypothesis about a psychopathological ground from which a criminological mechanism could emerge. Despite the lack of blatant psychosis, some traits might be identified in suicide-homicide cases - such as paranoid, psychopathic, narcissistic, melancholic - which can intertwine, potentiate one with another forming a distorted view of the world. The offense dynamic is possibly composed of preparatory behaviours, triggers, the use of death as a narcissistic support, identity choices… METHODS: The data were collected from scientific publications, personal cases, and open source. Despite the variety of behaviours included in this typology, we were able to identify a few mechanisms that could be found in two types of suicide-homicide [Private suicide-homicide (within the family circle) vs. Public space suicide-homicide (suicide by aircraft, school shooting…)]. Suicide-homicide phenomenon is the result of the interaction of societal, ideological, psychopathological and criminological elements which burst out in a lethal and paroxystic gesture. Psychiatrists and psychologists may have an important part to play in modelling a pattern to better understand it. Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS.

The second part of the study on homicides in East Berlin from 1980 to 1989 describes the solving of crimes, the usual features of offenders and the legal assessment according to East German law. Of the 139 homicides 126 crimes (= 90.6%) could be solved. Most of the offenders had a low social background and often belonged to the victim's circle of friends or family. Situational homicides and elimination crimes were the most common crimes. In the legal assessment sentences for murder were predominant.

Homicide in childhood: a public health problem in need of attention.

1984-01-01

Homicide is now among the five leading causes of death in childhood, accounting for 1/20 deaths of those less than 18 years of age. Based on childrens' changing developmental vulnerabilities, it is possible to characterize three subtypes of child homicide--infanticide, fatal child abuse and neglect after infancy, and homicide in the community. Specific approaches to primary prevention include measures to strengthen families and their community support systems, and to educate adults and children concerning appropriate behaviors of children at different ages.

Elderly homicide in Chicago: a research note.

2007-01-01

There is a body of knowledge about elderly crime victims, but we know little about the characteristics of elderly perpetrators, especially of homicide. The few studies that have been published are based on small samples and are somewhat dated. In an examination of homicides committed in Chicago over a 31-year period, we compared cases involving perpetrators aged over 60 years (n = 443) with those involving younger perpetrators (n = 24,066). There were a number of significant differences. Elderly killers were more likely to be White and to commit suicide afterwards. Their victims were more likely to be spouses, females, and aged over 60 years. Inter-racial homicide was more common for younger offenders. The low number of homicides involving the elderly is explained by reference to routine activity theory. Copyright 2007 John Wiley & Sons, Ltd.

International immigration, internal migration, and homicide in Canadian provinces.

PubMed

Andresen, Martin A

2013-05-01

The relationship between immigration and crime is politically charged and often fueled by the presence (or lack) of xenophobia. Many theoretical and empirical assessments of this relationship indicate that immigration does indeed lead to increased crime, but more recent (and very early) research investigating homicide calls this finding into question. The current analysis investigates the relationship between immigration and homicide using multiple measures of migration and Canadian provinces as the unit of analysis. It is found that the link between immigration and homicide is complex and dependent on the measure of migration used. Generally speaking, the results presented here are consistent with the more recent and very early research. Immigration, in and of itself, does not increase homicide. Rather it is the increase in the most criminogenic subpopulation that matters, that is young males.

The Situational Context of Adolescent Homicide Victimization in Johannesburg, South Africa.

Swart, Lu-Anne; Seedat, Mohamed; Nel, Juan

2018-02-01

Although studies have described the incidence and epidemiology of adolescent homicide victimization in South Africa, little is known about the situational contexts in which they occur. This study aimed to describe the victim, offender, and event characteristics of adolescent homicide and to generate a typology based on the particular types of situational contexts associated with adolescent homicide in South Africa. Data on homicides among adolescents (15-19 years) that occurred in Johannesburg (South Africa) during the period 2001-2007 were obtained from the National Injury Mortality Surveillance System (NIMSS) and police case records. Of the 195 cases available for analysis, 81% of the victims were male. Most of the offenders were male (90%), comprising of strangers (42%) and friends/acquaintances (37%). Arguments (33%) were the most common precipitating circumstances, followed by revenge (11%), robbery (11%), and acts of vigilantism/retribution for a crime (8%). Through the use of cluster analysis, the study identified three categories of adolescent homicide: (a) male victims killed by strangers during a crime-related event, (b) male victims killed by a friend/acquaintance during an argument, and (c) female victims killed by male offenders. The results can serve to inform the development of tailored and focused strategies for the prevention of adolescent homicide.

to describe mortality from homicides in Itabuna, in the State of Bahia. study with hybrid, ecological and time-trend design. The mortality coefficients per 1,000 inhabitants, adjusted by the direct technique, proportional mortality by sex and age range, and Potential Years of Life Lost were all calculated. since 2005, the external causes have moved from third to second most-common cause of death, with homicides being responsible for the increase. In the 13 years analyzed, homicides have risen 203%, with 94% of these deaths occurring among the male population. Within this group, the growth occurred mainly in the age range from 15 to 29 years of age. It was ascertained that 83% of the deaths were caused by firearms; 57.2% occurred in public thoroughfares; and 98.4% in the urban zone. In 2012, the 173 homicides resulted in 7,837 potential years of life lost, with each death causing, on average, the loss of 45.3 years. mortality by homicide in a medium-sized city in Bahia reaches levels observed in the big cities of Brazil in the 1980s, evidencing that the phenomenon of criminality - formerly predominant only in the big urban centers - is advancing into the rural area of Brazil, causing changes in the map of violent homicide in Brazil.

Objective To examine whether state-level spending on social and public health services is associated with lower rates of homicide in the USA. Design Ecological study. Setting USA. Participants All states in the USA and the District of Columbia for which data were available (n=42). Primary outcome measure Homicide rates for each state were abstracted from the US Department of Justice Federal Bureau of Investigation’s Uniform Crime Reporting. Results After adjusting for potential confounding variables, we found that every $10 000 increase in spending per person living in poverty was associated with 0.87 fewer homicides per 100 000 population or approximately a 16% decrease in the average homicide rate (estimate=−0.87, SE=0.15, p<0.001). Furthermore, there was no significant effect in the quartile of states with the highest percentages of individuals living in poverty but significant effects in the quartiles of states with lower percentages of individuals living in poverty. Conclusions Based on our findings, spending on social and public health services is associated with significantly lower homicide rates at the state level. Although we cannot infer causality from this research, such spending may provide promising avenues for homicide reduction in the USA, particularly among states with lower levels of poverty.

This paper aims to analyze the possible relationship between social determinants and homicide mortality in Fortaleza (CE), Brazil. To investigate whether the rate of mortality by homicides is related to social determinants, an ecological study with emphasis on spatial analysis was conducted in the city of Fortaleza. Social, economic, demographic and sanitation data, as well as information regarding years of potential life lost, and Human Development Index were collected. The dependent variable was the rate of homicides in the period 2004 to 2006. In order to verify the relationship between the outcome variable and the predictor variables, we performed a multivariate linear regression model. We found associations between social determinants and the rate of mortality by homicides. Variables related to income and education were proven determinants for mortality. The multiple regression model showed that 51% of homicides in Fortaleza neighborhoods are explained by years of potential life lost, proportion of households with poor housing, average years of schooling, per capita income and percentage of household heads with 15 or more years of study. The coefficients for years of potential life lost and households with poor housing were positive. The findings indicate that the mortality by homicide is associated with high levels of poverty and uncontrolled urbanization, which migrates to the peripheries of urban centers.

In order to assess the potential benefit in human lives if all geographical regions in the US (Northeast, South, Midwest, and West) achieved the lowest suicide and homicide rates observed within these regions, age-, race- and gender-adjusted suicide and homicide rates for each of the four regions were calculated based on data retrieved using the Centers for Disease Control and Prevention database for 1999-2004. Data on known risk factors were retrieved from online sources. Overall suicide rates (10.42 per 100,000) exceeded homicide rates (6.97 per 100,000). Almost 27% (12,942 lives per year) of the 288,222 suicide and homicide deaths during the study period might have been avoided if all US regions achieved the mortality rate reported by the Northeast. A firearm was used in 55% of all suicides and 66% of all homicides. In the total estimate of avoidable deaths, firearm suicides (90%) and firearm homicides (75%) were overrepresented. The Northeast had the lowest access to firearms (20%) contrasted to almost double in the other regions, whereas greater firearms availability was related to unrestricted firearm legislation. Measures to restrict firearms availability should be highly prioritized in the public health agenda in order to achieve an impressive benefit in human lives.

Unequal Burdens of Loss: Examining the Frequency and Timing of Homicide Deaths Experienced by Young Black Men Across the Life Course

PubMed Central

2015-01-01

Objectives. I examined the frequency and developmental timing of traumatic loss resulting from the health disparity of homicide among young Black men in Baltimore, Maryland. Methods. Using a modified grounded theory approach, I conducted in-depth semistructured interviews with 40 Black men (aged 18–24 years) from January 2012 to June 2013. I also constructed adapted life history calendar tools using chronologies of loss, and (1) provided a comprehensive history of loss, (2) determined a specific frequency of homicide deaths, (3) indicated participants’ relationship to the decedents, and (4) identified the developmental timing of deaths. Results. On average, participants knew 3 homicide victims who were overwhelmingly peers. Participant experiences of homicide death started in early childhood, peaked in adolescence, and persisted into emerging adulthood. The traumatic loss of peer homicide was a significant developmental turning point and disrupted participants’ social networks. Conclusions. The traumatic loss of peer homicide was a prevalent life course experience for young Black men and identified the need for trauma- and grief-informed interventions. Future research is needed to examine the physical and psychosocial consequences, coping resources and strategies, and developmental implications of traumatic loss for young Black men in urban contexts.

Public health agencies across the country are beginning to view violence as a problem that demands a public health response. However, before such a response can be mounted effectively, there must be a sound data-based understanding of this epidemic. With this in mind, the Chicago Department of Public Health implemented an epidemiological analysis of homicide in the city. Using vital records, police data, and census data, we found that the city's homicide rate in 1993 was 31 per 100,000 population. This rate placed Chicago 14th among other large cities in the United States and 4th out of the eight cities with a population > 1 million. The homicide rate in the city has been increasing over the past 30 years, but not steadily. For some intervals, the homicide rate has remained almost constant. African Americans, Hispanics, the young, and males are overrepresented in the epidemic. While guns accounted for almost 75% of all homicides in Chicago in 1993, gangs accounted for only 15%. Homicide cannot be viewed in isolation from the context of society. The literature suggests that poverty and racism are important risk factors for this epidemic. Although we cannot wait until these risk factors are remedied to develop violence prevention interventions, we also cannot proceed effectively without understanding this context.

After a 1996 firearm massacre in Tasmania in which 35 people died, Australian governments united to remove semi-automatic and pump-action shotguns and rifles from civilian possession, as a key component of gun law reforms. To determine whether Australia's 1996 major gun law reforms were associated with changes in rates of mass firearm homicides, total firearm deaths, firearm homicides and firearm suicides, and whether there were any apparent method substitution effects for total homicides and suicides. Observational study using official statistics. Negative binomial regression analysis of changes in firearm death rates and comparison of trends in pre-post gun law reform firearm-related mass killings. Australia, 1979-2003. Changes in trends of total firearm death rates, mass fatal shooting incidents, rates of firearm homicide, suicide and unintentional firearm deaths, and of total homicides and suicides per 100 000 population. In the 18 years before the gun law reforms, there were 13 mass shootings in Australia, and none in the 10.5 years afterwards. Declines in firearm-related deaths before the law reforms accelerated after the reforms for total firearm deaths (p=0.04), firearm suicides (p=0.007) and firearm homicides (p=0.15), but not for the smallest category of unintentional firearm deaths, which increased. No evidence of substitution effect for suicides or homicides was observed. The rates per 100 000 of total firearm deaths, firearm homicides and firearm suicides all at least doubled their existing rates of decline after the revised gun laws. Australia's 1996 gun law reforms were followed by more than a decade free of fatal mass shootings, and accelerated declines in firearm deaths, particularly suicides. Total homicide rates followed the same pattern. Removing large numbers of rapid-firing firearms from civilians may be an effective way of reducing mass shootings, firearm homicides and firearm suicides.

Homicide and geographic access to gun dealers in the United States

Background Firearms are the most commonly used weapon to commit homicide in the U.S. Virtually all firearms enter the public marketplace through a federal firearms licensee (FFL): a store or individual licensed by the federal government to sell firearms. Whether FFLs contribute to gun-related homicide in areas where they are located, in which case FFLs may be a homicide risk factor that can be modified, is not known. Methods Annual county-level data (1993–1999) on gun homicide rates and rates of FFLs per capita were analyzed using negative binomial regression controlling for socio-demographic characteristics. Models were run to evaluate whether the relation between rates of FFLs and rates of gun homicide varied over the study period and across counties according to their level of urbanism (defined by four groupings, as below). Also, rates of FFLs were compared against FS/S – which is the proportion of suicides committed by firearm and is thought to be a good proxy for firearm availability in a region – to help evaluate how well the FFL variable is serving as a way to proxy firearm availability in each of the county types of interest. Results In major cities, gun homicide rates were higher where FFLs were more prevalent (rate ratio [RR] = 1.70, 95% CI 1.03–2.81). This association increased (p < 0.01) from 1993 (RR = 1.69) to 1999 (RR = 12.72), due likely to federal reforms that eliminated low-volume dealers, making FFL prevalence a more accurate exposure measure over time. No association was found in small towns. In other cities and in suburbs, gun homicide rates were significantly lower where FFLs were more prevalent, with associations that did not change over the years of the study period. FFL prevalence was correlated strongly (positively) with FS/S in major cities only, suggesting that the findings for how FFL prevalence relates to gun homicide may be valid for the findings pertaining to major cities but not to counties of other types. Conclusion Modification of FFLs through federal, state, and local regulation may be a feasible intervention to reduce gun homicide in major cities. PMID:19549293

Annual county-level data (1993-1999) on gun homicide rates and rates of FFLs per capita were analyzed using negative binomial regression controlling for socio-demographic characteristics. Models were run to evaluate whether the relation between rates of FFLs and rates of gun homicide varied over the study period and across counties according to their level of urbanism (defined by four groupings, as below). Also, rates of FFLs were compared against FS/S - which is the proportion of suicides committed by firearm and is thought to be a good proxy for firearm availability in a region - to help evaluate how well the FFL variable is serving as a way to proxy firearm availability in each of the county types of interest. In major cities, gun homicide rates were higher where FFLs were more prevalent (rate ratio [RR] = 1.70, 95% CI 1.03-2.81). This association increased (p < 0.01) from 1993 (RR = 1.69) to 1999 (RR = 12.72), due likely to federal reforms that eliminated low-volume dealers, making FFL prevalence a more accurate exposure measure over time. No association was found in small towns. In other cities and in suburbs, gun homicide rates were significantly lower where FFLs were more prevalent, with associations that did not change over the years of the study period. FFL prevalence was correlated strongly (positively) with FS/S in major cities only, suggesting that the findings for how FFL prevalence relates to gun homicide may be valid for the findings pertaining to major cities but not to counties of other types. Modification of FFLs through federal, state, and local regulation may be a feasible intervention to reduce gun homicide in major cities.

Objectives To estimate the rate of mental disorder in those convicted of homicide and to examine the social and clinical characteristics of those with a history of contact with psychiatric services. Design National clinical survey. Setting England and Wales. Subjects Eighteen month sample of people convicted of homicide. Main outcome measures Offence related and clinical information collected from psychiatric court reports on people convicted of homicide. Detailed clinical data collected on those with a history of contact with psychiatric services. Results 718 homicides were reported to the inquiry between April 1996 and November 1997. Of the 500 cases for whom psychiatric reports were retrieved, 220 (44%; 95% confidence interval 40% to 48%) had a lifetime history of mental disorder, while 71 (14%; 11% to 17%) had symptoms of mental illness at the time of the homicide. Of the total sample, 102 (14%; 12% to 17%) were confirmed to have been in contact with mental health services at some time, 58 (8%; 6% to 10%) in the year before the homicide. The commonest diagnosis was personality disorder (20 cases, 22%; 13% to 30%). Alcohol and drug misuse were also common. Only 15 subjects (18%; 10% to 26%) were receiving intensive community care, and 60 (63%; 53% to 73%) were out of contact at the time of the homicide. Conclusions There are substantial rates of mental disorder in people convicted of homicide. Most do not have severe mental illness or a history of contact with mental health services. Inquiry findings suggest that preventing loss of contact with services and improving the clinical management of patients with both mental illness and substance misuse may reduce risk, but clinical trials are needed to examine the effectiveness of such interventions. Key messagesPeople convicted of homicide have substantial rates of mental disorderMost do not have severe mental illness or a history of contact with mental health servicesMental health services need to prevent loss of contact with patientsThe clinical management of patients with both mental illness and substance misuse needs to be improved PMID:10231252

The incidence of homicide-related death among individuals of college age in the United States population is estimated at 15.5/100,000. The incidence of homicide among National Collegiate Athletic Association (NCAA) athletes is unknown. To investigate the rate of homicide-related death in NCAA athletes and to identify associated risk factors. The NCAA Resolutions list, NCAA catastrophic insurance claims, media reports, and published NCAA demographic data were used to identify student athlete deaths and total participant seasons from 2003-04 through 2012-13. Homicide-related deaths were analysed by sex, race, division, sport, method, location, and circumstance. Internet searches were used to gather case details. Forty-two cases of homicide-related death were identified from 4,242,519 individual participant seasons during the ten-year study period. The incidence of homicide-related death in NCAA athletes was 1.0/100,000. The incidence in males was 1.45/100,000 and in females was 0.4/100,000 (relative risk (RR) 2.9, p=0.01). The incidence in black athletes was 4.2/100,000 and in white athletes was 0.4/100,000 (RR 7.0, p<0.001). The highest sport-specific homicide-related death rate was in American football (3.7/100,000), with a RR of 4.4 (p=0.002) compared to all other sports. 88% of cases occurred off-campus. 38% of cases occurred at a social gathering, and 38% of cases occurred in a place of residence. 74% involved a fatal shooting. Homicide-related deaths in NCAA athletes occur most commonly in males, black athletes, and American football players. Understanding the incidence, risk factors, and circumstances of homicide-related deaths in college athletes may assist NCAA institutions in developing preventative measures.

Differentiation of homicidal child molesters, nonhomicidal child molesters, and nonoffenders by phallometry.

PubMed

Firestone, P; Bradford, J M; Greenberg, D M; Nunes, K L

2000-11-01

The purpose of this study was to examine the ability of phallometry to discriminate among homicidal child molesters, nonhomicidal child molesters, and a comparison group of nonoffenders. Twenty-seven child molesters who had committed or had attempted a sexually motivated homicide, 189 nonhomicidal child molesters, and 47 nonoffenders were compared on demographic variables and psychometrically determined responses to aural descriptions of sexual vignettes. Two phallometric indexes were used: the pedophile index and the pedophile assault index. The pedophile index was computed by dividing the subject's highest response to an aural description of sex with a "consenting" child by his highest response to description of sex with a consenting adult. The pedophile assault index was computed by dividing the subject's highest response to an aural description of assault involving a child victim by his highest response to description of sex with a "consenting" child. Homicidal child molesters, nonhomicidal child molesters, and nonoffenders were not significantly different in age or IQ. Homicidal and nonhomicidal child molesters had significantly higher pedophile index scores than nonoffenders. Significantly more homicidal child molesters (14 [52%] of 27) and nonhomicidal child molesters (82 [46%] of 180) than nonoffenders (13 [28%] of 47) had pedophile index scores equal to or greater than 1.0, but homicidal and nonhomicidal child molesters did not differ from each other. Significantly more homicidal child molesters (17 [63%] of 27) than either nonhomicidal child molesters (71 [40%] of 178) or nonoffenders (17 [36%] of 47) had pedophile assault index scores equal to or greater than 1.0, and nonhomicidal child molesters and nonoffenders were not significantly different from each other. Within-group analyses revealed that of the three groups, only the nonhomicidal child molesters exhibited a significant difference between their pedophile index scores and their pedophile assault index scores; their pedophile index scores were higher. Consistent with past research, the authors found that the pedophile index is useful in differentiating homicidal and nonhomicidal child molesters from nonoffenders and that the pedophile assault index is able to differentiate homicidal child molesters from nonhomicidal child molesters and nonoffenders.

Driving a taxicab remains one of the most dangerous occupations in the United States, with leading homicide rates. Although safety equipment designed to reduce robberies exists, it is not clear what effect it has on reducing taxicab driver homicides. Taxicab driver homicide crime reports for 1996 through 2010 were collected from 20 of the largest cities (>200,000) in the United States: 7 cities with cameras installed in cabs, 6 cities with partitions installed, and 7 cities with neither cameras nor partitions. Poisson regression modeling using generalized estimating equations provided city taxicab driver homicide rates while accounting for serial correlation and clustering of data within cities. Two separate models were constructed to compare (1) cities with cameras installed in taxicabs versus cities with neither cameras nor partitions and (2) cities with partitions installed in taxicabs versus cities with neither cameras nor partitions. Cities with cameras installed in cabs experienced a significant reduction in homicides after cameras were installed (adjRR = 0.11, CL 0.06-0.24) and compared to cities with neither cameras nor partitions (adjRR = 0.32, CL 0.15-0.67). Cities with partitions installed in taxicabs experienced a reduction in homicides (adjRR = 0.78, CL 0.41-1.47) compared to cities with neither cameras nor partitions, but it was not statistically significant. The findings suggest cameras installed in taxicabs are highly effective in reducing homicides among taxicab drivers. Although not statistically significant, the findings suggest partitions installed in taxicabs may be effective.

Black-on-black homicide: Kansas City's response.

PubMed Central

Mitchell, M A; Daniels, S

1989-01-01

In many metropolitan areas, homicide continues to be the scourge of black Americans despite increasing awareness of the overrepresentation of blacks among victims and perpetrators. The risk of being a homicide victim among black males is so high that the Department of Health and Human Services has set a priority of reducing the risk to 60 per 100,000 by 1990. The recent escalation in the number of homicides in the United States associated with drugs makes attainment of that goal unlikely. In Kansas City, a black community grassroots organization, the Ad Hoc Group Against Crime, commissioned a multidisciplinary task force to study black-on-black homicide in 1986. The report generated by this task force identified factors placing Kansas Citians at high risk of being homicide victims or perpetrators, including being black, male, unemployed, between the ages 17-29, a high school nongraduate, frequently involved in or around violence, and having prior arrests on weapons charges. One hundred recommendations were made, of which 12 were targeted for immediate implementation. These included increasing public awareness of the incidence of black-on-black homicide, involvement of black men in role model programs for young black males, training in anger control and alternatives to violence for those identified as being at high risk for homicide, and providing a role for ex-offenders in violence prevention. Working with community organizations has inherent strengths and weaknesses for public health workers. However, such a group can successfully impact the affected community in ways which would be difficult for traditional resources. PMID:2511593

Homicide in discharged patients with schizophrenia and other psychoses: a national case-control study.

PubMed

Fazel, Seena; Buxrud, Petra; Ruchkin, Vladislav; Grann, Martin

2010-11-01

To investigate factors associated with homicide after discharge from hospital in patients with schizophrenia and other psychoses. All homicides committed by patients with psychosis within 6 months of hospital discharge were identified in Sweden from 1988-2001 and compared with patients with psychoses discharged over the same time period who did not subsequently commit any violent offences. Medical records were then collected, and data extracted using a validated protocol. Interrater reliability tests were performed on a subsample, and variables with poor reliability excluded from subsequent analyses. We identified 47 cases who committed a homicide within 6 months of discharge, and 105 controls who did not commit any violent offence after discharge. On univariate analyses, clinical factors on admission associated with homicide included evidence of poor self-care, substance misuse, and being previously hospitalized for a violent episode. Inpatient characteristics included having a severe mental illness for one year prior to admission. After-care factors associated with homicide were evidence of medication non-compliance and substance misuse. The predictive validity of combining two or three of these factors was not high. Depression appeared to be inversely associated with homicide, and there was no relationship with the presence of delusions or hallucinations. There are a number of potentially treatable factors that are associated with homicide in schizophrenia and other psychoses. Associations with substance misuse and treatment compliance could be the focus of therapeutic interventions if validated in other samples. However, their clinical utility in violence risk assessment remains uncertain. Copyright © 2010 Elsevier B.V. All rights reserved.

[Impact of homicide on male life expectancy in Mexico].

González-Pérez, Guillermo Julián; Vega-López, María Guadalupe; Cabrera-Pivaral, Carlos Enrique

2012-11-01

To determine the impact of homicide on male life expectancy in Mexico and its 32 states during the three-year periods 1998-2000 and 2008-2010 and the weight of the different age groups in years of life expectancy lost (YLEL) due to this cause. Based on official death and population data, abridged tables for male mortality in Mexico as a whole and its states were created for the three-year periods studied. Health-adjusted life expectancy and YLEL for men aged 15 to 75 were calculated by selected causes (homicide, diabetes mellitus, and traffic accidents) and age groups in each three-year period. In the years between the 1998-2000 and 2008-2010 periods, YLEL due to homicide increased both nationally and in 19 states. In four states, the YLEL in 2008-2010 exceeded two, with the state of Chihuahua standing out at 5.2 years. In 14 of the 18 states where health-adjusted life expectancy among men declined between the two three-year periods, the YLEL due to homicide increased. From 2008 to 2010, homicides were the leading cause of YLEL among men aged 20-44. YLEL due to homicide among those aged 15-44 increased between the two three-year periods. The increase in the rate of homicidal violence, especially among young people, is impeding an increase in male life expectancy in Mexico. In several states, such as Chihuahua and Durango, this violence appears to be the main reason for the decline in life expectancy among men aged 15 to 75.

Law enforcement officers (LEOs) in the U.S. are at an increased risk for homicide. The purpose of this study is to describe the characteristics of homicides of LEOs in 17 U.S. states participating in the National Violent Death Reporting System. This active surveillance system uses data from death certificates, coroner/medical examiner reports, and law enforcement reports. This study used quantitative and qualitative methods to analyze National Violent Death Reporting System data for 2003-2013. Deaths of LEOs feloniously killed in the line of duty were selected for analysis. LEO homicides and the circumstances preceding or occurring during the incident were characterized. Analyses were conducted October 2015-June 2016. A total of 128 officer homicides from 121 incidents were identified. Most (93.7%) LEO victims were male, 60.9% were aged 30-49 years (average age, 40.9 years). Approximately 21.9% of LEOs were killed during an ambush, and 19.5% were killed during traffic stops or pursuits. Of the 14.1% of LEOs killed responding to domestic disturbances, most disturbances were intimate partner violence related. More than half (57.0%) of homicides were precipitated by another crime, and of these, 71.2% involved crimes in progress. Most suspects were male. Ninety-one percent of homicides of LEOs were committed with a firearm. This information is critical to help describe encounter situations faced by LEOs. The results of this study can be used to help educate and train LEOs on hazards, inform prevention efforts designed to promote LEO safety, and prevent homicide among this population.

Homicide is one of the leading causes of mortality in the World. Homicide risk factors vary significantly between countries and regions. In Rwanda, data on homicide victimization is unreliable because no standardized surveillance system exists. This study was undertaken to identify the risk factors for homicide victimization in Rwanda with particular attention on the latent effects of the 1994 genocide. A population-based matched case-control study was conducted, with subjects enrolled prospectively from May 2011 to May 2013. Cases of homicide victimization were identified via police reports, and crime details were provided by law enforcement agencies. Three controls were matched to each case by sex, 5-year age group and village of residence. Socioeconomic and personal background data, including genocide exposure, were provided via interview of a family member or through village administrators. Conditional logistic regression, stratified by gender status, was used to identify risk factors for homicide victimization. During the study period, 156 homicide victims were enrolled, of which 57 % were male and 43 % were female. The most common mechanisms of death were wounds inflicted by sharp instruments (knives or machetes; 41 %) followed by blunt force injuries (36.5 %). Final models indicated that risk of homicide victimhood increased with victim alcohol drinking patterns. There was a dose response noted for alcohol use: for minimal drinking versus none, adjusted odds ratio (aOR) = 3.1, 95%CI: 1,3-7.9; for moderate drinking versus none, aOR = 10.1, 95%CI: 3.7-24.9; and for heavy drinking versus none, aOR = 11.5, 95%CI: 3.6-36.8. Additionally, having no surviving parent (aOR = 2.7, 95%CI: 1.1-6.1), previous physical and/or sexual abuse (aOR = 28.1, 95%CI: 5.1-28.3) and drinking illicit brew and/or drug use (aOR = 7.7, 95%CI: 2.4-18.6) were associated with a higher risk of being killed. The test of interaction revealed that the variables that were significantly associated with a higher risk of homicide victimhood, did not exhibit any difference according to sex of the victim. However, the effect of belonging to a religion differed between women and men, but was significantly protective for both (aOR = 0.002, 95%CI: 0.001-0.054 and aOR = 0.20, 95%CI: 0.052-0.509, respectively). Homicide victims in Rwanda are relatively young and the proportion of female victims is one of the highest globally. Contrary to the initial study considerations, genocide exposure (either as a survivor or perpetrator) was not a significant predictor of homicide victimization. Rather, risk factors were similar to those described in other countries, regardless of gender status. Sensitizing communities against alcohol heavy drinking, and illicit brew drinking and/or drug abuse and physical or sexual violence could reduce the homicide rate in Rwanda.

2000-01-01

Curfews are implemented to curtail youth violence. Trauma systems and emergency medical services (EMS) may need to prepare for changes in patient volume resulting from local ordinances. This study evaluated the impact of the 1995 Washington, DC, Juvenile Curfew Act on EMS transports of injured youth and on youth homicides. A retrospective, comparative cohort study was performed. Transports of injured youth and youth homicides were counted in corresponding months of 1994 and 1995. Cohorts were formed by year, time of day, age group, and mechanism of injury. Year-to-year statistical comparisons of injury proportions were performed using the chi square and Fisher's exact tests. One thousand forty-eight transports were included. No significant difference was observed in transports with curfew implementation. Most assaults on youth occurred outside the curfew time. No effect of the curfew on homicides was detected. Of 67 homicides, only two victims were under the curfew. No effect of the curfew on transports for injuries or on homicides was demonstrated. The curfew was not in effect during the period of highest risk.

2008-03-05

In the present, the morbidity of psychiatric disorders of homicide/attempted homicide crime convicts imprisoned in Turkey, Sivas maximum security prison was investigated. Seventy imprisoned homicide/attempted homicide crime convicts included in this study. Sociodemographic information form, structured clinical interview for DSM-IV Axis-I disorders and structured clinical interview for DSM-III-R personality disorders applied to the participants. Most commonly diagnosed disorders among those convicts were current Axis-I disorders, depressive disorders (7.1%) and anxiety disorders (5.7%). Among Axis-I disorders, the most diagnosed one was the substance use disorders (45.7%). The most diagnosed Axis-II disorder was found as to be antisocial personality disorder (48.6%). The rate of convicts who were diagnosed as having both Axis-I and Axis-II disorders was 51.4%. The most prevalently accompanying lifetime Axis-I disorders to antisocial personality disorder with respect to Axis-I, and Axis-II comorbidity was substance use disorders. As a result, it was thought that the substance use disorders and antisocial personality disorder among the homicide/attempted homicide crime convicts were the most prevalent lifetime psychiatric disorders.

Homicide, schizophrenia and substance abuse or dependency.

Beaudoin, M N; Hodgins, S; Lavoie, F

1993-10-01

Few studies have extensively studied the aggressive behaviours of mentally disordered offenders. This investigation compared 14 schizophrenics found not guilty of homicide by reason of insanity (NGRI) with 12 schizophrenics convicted of homicide. A comparison group of 15 homicide offenders with no major mental disorder was used. Drug and alcohol consumption, previous history of aggression against others as well as mental health were assessed using standardized, reliable, valid instruments. Significantly more of the inmates with no major mental disorder were diagnosed as having a history of drug or alcohol abuse or dependency (60%) than the NGRI schizophrenics (35.7%). In addition, both groups of convicted homicide offenders were more likely to have committed homicide under the influence of drugs or alcohol than the NGRI group. No significant difference distinguished the groups for the mean number of aggressive incidents. The subjects found NGRI assaulted more often during an acute phase of mental illness than the convicted schizophrenics. Although both groups appeared to have a similar number of hospitalizations, most of the hospitalizations of the convicted schizophrenics occurred after the crime.

Obesity, Body Mass Index, and Homicide.

2017-07-01

The body mass indexes (BMIs) of 100 randomly selected homicide cases from the files of Forensic Science SA were compared to the Australian and South Australian populations. There were 70 males and 30 females (M:F = 2.3:1; age range 18-84 years; mean 42.3 years). There was a substantially lower proportion of obese individuals in the homicide population compared to the general Australian and South Australian populations (19% [vs.] 27.9% and 30%, respectively). A second group of 144 randomly selected autopsy cases where the BMI was ≥40 kg/m 2 was analyzed. There were 77 males and 67 females (M:F = 1.2:1; age range 23-78 years; mean 46.7 years). The majority of deaths were natural (N = 108), with no homicides. A negative association between obesity and homicide has, therefore, been demonstrated. Reasons for the lower numbers of obese/morbidly obese individuals among homicide victims are unclear, but may include physical protection afforded by fat padding from sharp force injuries, and relative sociodemographic isolation. © 2016 American Academy of Forensic Sciences.

To analyze the impact of the Tunisian Revolution on suicide and homicide patterns in Tunisia. It is a retrospective, cross-sectional study, including all the cases of homicides and suicides that occurred during an 8-year period (2007-2014) in Northern Tunisia. We compared data before and after the revolution. After the revolution, the number of suicides rose 1.7 times, with a prevalence rising from 1.8 to 3.12 suicides per 100,000 persons per year. Homicides rose 1.3 times after the revolution. For both manner of death, victims were mostly males, aged between 20 and 39 years, living in urban areas. Hanging and self-immolation rose, respectively, 1.8 and 3 times after 2011. We observed suicide cases most frequently occurred in public places and in front of public administration after 2011. Homicide victims' profile and circumstances showed a single variation which is an increase in number of cases happening in rural areas. Our results proved a short-term impact of the transition period on homicides and suicides. Urgent preventive measures are needed especially to decrease the suicide rates.

OBJECTIVES: This study determined the effect of income inequality on homicide rates in the state of Rio de Janeiro, Brazil. METHODS: We conducted an ecological study at 2 geographical levels, municipalities in the state of Rio de Janeiro and administrative regions in the municipality of Rio de Janeiro. The association between homicide and income inequality was tested by multiple regression procedures, with adjustment for other socioeconomic indicators. RESULTS: For the municipalities of Rio de Janeiro State, no association between homicide and income concentration was found an outcome that can be explained by the municipalities' different degrees of urbanization. However, for the administrative regions in the city of Rio de Janeiro, the 2 income inequality indicators were strongly correlated with the outcome variable (P < .01). Higher homicide rates were found precisely in the sector of the city that has the greatest concentration of slum residents and the highest degree of income inequality. CONCLUSIONS: The findings suggest that social policies specifically aimed at low-income urban youth, particularly programs to reduce the harmful effects of relative deprivation, may have an important impact on the homicide rate.

[Three phases of homicidal violence in Venezuela].

PubMed

Briceño-León, Roberto

2012-12-01

Venezuela was considered one of the least violent countries in Latin America, however by 2010 it was among the countries with the highest homicide rate. This article analyzes the evolution of homicides in Venezuela between 1985 and 2010 and proposes the existence of three stages which correspond to trends in social and political institutions of the country. The first from 1985 to 1993, characterized by the looting of 1989 and the coups d'état of 1992, when for the first time the homicide rate rose from 8 to 20. The second phase from 1994 to 1998 was a recovery period of the institutional and political stability when the homicide rate remained constant at around 20. The third phase began in 1999 with the H Chavez government and the institutional destruction that comes with the Bolivarian revolution and caused an increase in the rate of 20 to 57 homicides per 100 thousand inhabitants. This article argues that the explanation for the changes in the phases is to be found in the transformation of social and political institutions.

[A Retrospective Analysis of 88 Solved Intentional Homicide Cases].

To summarize the key points, difficulties and relevant practical experiences for analyzing the scene of solved intentional homicide cases. The data of 88 solved intentional homicide cases in a county from 2004 to 2013 were collected and the retrospective analysis was performed. The number of local female victims obviously higher than non-local female victims and the number of non-local suspects is obviously higher than local suspects. The number of Male suspects showed higher compared with the female. Most of them were temporary workers, unemployment or farmers with less education backgrounds. The main causes of victims' death were mechanical injury or asphyxia. The murders were acquaintances in most intentional homicide cases. The motive of the stranger murders was commonly money. The murder behavior types of homicide cases were related with people, money and sexual assault. Camouflage and guilty behavior showed the most significance. The accurate identification of suspects is one of the most important task in forensic investigation and reflects the importance of the criminal scene analysis for intentional homicide cases. It also provides the direction of future research.

This study investigated the epidemiological profile of female homicide victims in Recife, Pernambuco State, Northeast Brazil. An observational descriptive and prospective study included all homicides from March 2009 to February 2010 with female victims from Recife, 10 to 49 years of age. A questionnaire was used to record socioeconomic, demographic, and biological risk factors. Relatives of the victims were interviewed, and data were collected from death certificates. We identified 60 homicides during the study period. Most victims were adult women with brown skin color and low schooling and low income. Other characteristics included smoking in 39.7%, alcohol and illicit drugs in 48.3% and 24.1%, respectively, and physical and/or sexual violence in the 12 months prior to the murder in 29.3%. Firearms were used in 69% of these homicides.

Firearm homicide in Australia, Canada, and New Zealand: what can we learn from long-term international comparisons?

2011-01-01

Although firearm homicide remains a topic of interest within criminological and policy discourse, existing research does not generally undertake longitudinal comparisons between countries. However, cross-country comparisons provide insight into whether "local" trends (e.g., declines in firearm homicide in one particular country) differ from broader, international trends. This in turn can improve knowledge about the role of factors such as policing practices and socioeconomic variables in the incidence of lethal violence using firearms. The current study compares long-term firearm homicide trends in three countries with similar social histories but different legislative regimes: Australia, Canada, and New Zealand. Using negative binomial regression, the study found that the most pronounced decline in firearm homicide over the past two decades occurred in New Zealand. Connections between social disadvantage, policing policy, and violence are discussed.

Messing Up Texas?: A Re-Analysis of the Effects of Executions on Homicides.

Brandt, Patrick T; Kovandzic, Tomislav V

2015-01-01

Executions in Texas from 1994-2005 do not deter homicides, contrary to the results of Land et al. (2009). We find that using different models--based on pre-tests for unit roots that correct for earlier model misspecifications--one cannot reject the null hypothesis that executions do not lead to a change in homicides in Texas over this period. Using additional control variables, we show that variables such as the number of prisoners in Texas may drive the main drop in homicides over this period. Such conclusions however are highly sensitive to model specification decisions, calling into question the assumptions about fixed parameters and constant structural relationships. This means that using dynamic regressions to account for policy changes that may affect homicides need to be done with significant care and attention.

Faith without answers: the use of religion among cold case homicide survivors.

PubMed

Wellman, Ashley R P

2014-01-01

Through data gathered from interviews with cold case homicide survivors, this article reveals the important role of religion and faith in the aftermath of an unsolved murder. Using qualitative methodology, the author highlights the lived experiences and personal journeys of cold case homicide surviving family members, who are often a forgotten and an overlooked segment of victims. Qualitative data suggests that these cold case homicide survivors found religion to be critical in the aftermath of their loved one's murder. Specifically, survivors indicated their faith was fundamental in coping with the homicide and provided hope for anticipating a resolution in their cases. From these intimate, personal survivor accounts, scholars and practitioners can begin to develop future research and programs that are specifically designed to highlight the role of religion in moving forward after an unsolved murder.

Firearm homicides and suicides in major metropolitan areas - United States, 2006-2007 and 2009-2010.

PubMed

2013-08-02

Firearm homicides and suicides are a continuing public health concern in the United States. During 2009-2010, a total of 22,571 firearm homicides and 38,126 firearm suicides occurred among U.S. residents. This includes 3,397 firearm homicides and 1,548 firearm suicides among persons aged 10-19 years; the firearm homicide rate for this age group was slightly above the all-ages rate. This report updates an earlier report that provided statistics on firearm homicides and suicides in major metropolitan areas for 2006-2007, with special emphasis on persons aged 10-19 years in recognition of the importance of early prevention efforts. Firearm homicide and suicide rates were calculated for the 50 most populous U.S. metropolitan statistical areas (MSAs) for 2009-2010 using mortality data from the National Vital Statistics System (NVSS) and population data from the U.S. Census Bureau. Comparison statistics were recalculated for 2006-2007 to reflect revisions to MSA delineations and population estimates subsequent to the earlier report. Although the firearm homicide rate for large MSAs collectively remained above the national rate during 2009-2010, more than 75% of these MSAs showed a decreased rate from 2006-2007, largely accounting for a national decrease. The firearm homicide rate for persons aged 10-19 years exceeded the all-ages rate in many of these MSAs during 2009-2010, similar to the earlier reporting period. Conversely, although the firearm suicide rate for large MSAs collectively remained below the national rate during 2009-2010, nearly 75% of these MSAs showed an increased rate from 2006-2007, paralleling the national trend. Firearm suicide rates among persons aged 10-19 years were low compared with all-ages rates during both periods. These patterns can inform the development and monitoring of strategies directed at reducing firearm-related violence.

Pre-offense alcohol intake in homicide offenders and victims: A forensic-toxicological case-control study.

Alcohol is associated with violent behavior, although little is known regarding to what extent alcohol increases homicide risk. We aimed to estimate risks of homicide offending and victimization conferred by the presence of ethanol in blood by using toxicological data from homicide victims and offenders and from controls who had died in vehicle-related accidents. From nationwide governmental registries and databases, forensic-toxicological results were retrieved for victims (n = 200) and offenders (n = 105) of homicides committed during the years 2007-2009 and individuals killed in vehicle-related accidents (n = 1629) during the years 2006-2014. Ethanol levels in blood exceeding 0.01 g/100 ml were considered positive. Using logistic regression, we found that the presence of ethanol in blood conferred a significantly increased risk of homicide offending (age-adjusted odds ratio [aOR] = 3.6, 95% confidence interval [95% CI] = 2.3-5.6) and homicide victimization (aOR = 2.1, 95% CI = 1.4-3.0). After stratification by sex, risk estimates in females were about 3-fold greater than in males for both homicide offending ([aOR = 11.0, 95% CI = 2.4-49.8] versus [aOR = 3.1, 95% CI = 1.9-4.9]) and victimization ([aOR = 5.4, 95% CI = 2.4-12.2] versus [aOR = 1.7, 95% CI = 1.1-2.8]). Sensitivity analyses yielded similar estimates. The results of the present study are consistent with prior findings suggesting alcohol to be an important risk factor for homicide offending and victimization. Surprisingly, however, associations were more pronounced in females, although additional studies that control for potential confounders are warranted to facilitate speculations about causality.

A study of multiple homicides or multiple deaths involving a solitary incident of violence by another individual was performed on the case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, Florida, during 1983-1987. A total of 107 multiple homicides were studied: 88 double, 17 triple, one quadruple, and one quintuple. The 236 victims were analyzed regarding age, race, sex, cause of death, toxicologic data, perpetrator, locale of the incident, and reason for the incident. This article compares this type of slaying with other types of homicide including those perpetrated by serial killers. Suggestions for future research in this field are offered.

Repercussions of homicide on victims' families: a literature review.

Costa, Daniella Harth da; Njaine, Kathie; Schenker, Miriam

2017-09-01

This study aimed to perform a integrative literature review on the repercussion of homicide on victims' families from 1990 to June 2015. It was noted that the majority of studies on the subject has been conducted in the United States. Fewer studies carried out in Brazil and in other countries have been located. Four main themes have been identified: impact on health, the family system in the post-homicide period, re-victimization factors and post-homicide facilitating aspects. Findings of this study point to the importance of interdisciplinary care focused on this public, considering their health, social, financial and legal needs.

Rates of firearm homicide by Chicago region, age, sex, and race/ethnicity, 2005-2010.

Walker, Garth Nyambi; McLone, Suzanne; Mason, Maryann; Sheehan, Karen

2016-10-01

The United States reports the highest levels of firearm homicide incidences compared to other high income countries, and the focus and causes of these incidences within the US differ by demographic characteristics and location such as urban versus rural environment. Despite these findings, few studies have published on rates varied by region within a city. This study aims to provide descriptive analysis of the rates of firearm homicide by age, sex, and race/ethnicity in each of the seven City of Chicago regions, and to determine if the rates of firearm homicide differ by demographics among the seven City of Chicago regions. The Illinois Violent Death Reporting System conducts routine surveillance of violent deaths. Decedents were selected according to the following criteria: manner of death was homicide, weapon type was firearm, and location of injury that led to death was the City of Chicago. Location of injury was broken down by regions: North, Northwest, Center, West, South, Southwest, and Far South. Multiyear rates per 100,000 and corresponding 95% confidence intervals were calculated. There were 2,254 victims of homicide by firearm in the City of Chicago. The overall rate across Chicago for all demographics was 12.9 (12.1-13.5 per 100,000) with an average age of 27.4. The highest age group (20-24) for firearm homicide rates was 43.2 (39.7-46.7) per 100,000. For the youngest age group (10-14), only the Southwest (3.3-10.4) region reported any firearm incidence. The 20 to 24 age group reported the highest rates of all age groups within the South (107.9-151.7), West (80.3-108.2), and Far South (69.6-105.3) regions, whereas the North and Northwest reported the lowest rates for all regions by age. Black firearm homicide rates were 33.5 (31.9-35.1) per 100,000 versus Hispanic and non-Hispanic white firearm homicide rates of 8.5 (7.7-9.3) and 1.2 (1-1.5) per 100,000, respectively. Lastly, the West reported the highest firearm rates at 29.1 (657). In conclusion, Chicago is a large city that has high variation in firearm homicide rates among its constituent regions; therefore, an overall firearm homicide rate for the city of Chicago as a whole is not an accurate representation of the true nature of firearm homicides. Policy implementation may be made more effective by providing more regional analysis and targeted interventions via multipronged initiatives to help reduce future firearm rates, and funding for issues that address systemic poverty and adequate access to care and medical facilities.

In 2016, firearms killed 38,658 people in the United States. Federal law requires licensed gun dealers, but not private parties, to conduct background checks on prospective firearm purchasers with the goal of preventing prohibited persons from obtaining firearms. Our objective was to estimate the effect of the repeal of comprehensive background check laws - requiring a background check for all handgun sales, not just sales by licensed dealers - on firearm homicide and suicide rates in Indiana and Tennessee. We compared age-adjusted firearm homicide and suicide rates, measured annually from 1981-2008 and 1994-2008 in Indiana and Tennessee, respectively, to rates in control groups constructed using the synthetic control method. The average rates of firearm homicide and suicide in Indiana and Tennessee following repeal were within the range of what could be expected given natural variation (differences = 0.7 firearm homicides and 0.5 firearm suicides per 100,000 residents in Indiana and 0.4 firearm homicides and 0.3 firearm suicides per 100,000 residents in Tennessee). Sensitivity analyses resulted in similar findings. We found no evidence of an association between the repeal of comprehensive background check policies and firearm homicide and suicide rates in Indiana and Tennessee. In order to understand whether comprehensive background check policies reduce firearm deaths in the United States generally, more evidence on the impact of such policies from other states is needed.

Rapid-Sequence Serial Sexual Homicides.

2017-03-01

Serial sexual murderers have been described as committing homicides in a methodical manner, taking substantial time between offenses to elude the authorities. The results of our study of the temporal patterns (i.e., the length of time between homicides) of a nonrandom national sample of 44 serial sexual murderers and their 201 victims indicate that this representation may not always be accurate. Although 25 offenders (56.8%) killed with longer than a 14-day period between homicides, a sizeable subgroup was identified: 19 offenders (43.2%) who committed homicides in rapid-sequence fashion, with fewer than 14 days between all or some of the murders. Six offenders (13.6%) killed all their victims in one rapid-sequence, spree-like episode, with homicides just days apart or sometimes two murders in the same day. Thirteen offenders (29.5%) killed in one or two rapid-sequence clusters (i.e., more than one murder within a 14-day period, as well as additional homicides with greater than 14 days between each). The purpose of our study was to describe this subgroup of rapid-sequence offenders who have not been identified until now. These findings argue for accelerated forensic assessments of dangerousness and public safety when a sexual murder is detected. Psychiatric disorders with rapidly occurring symptom patterns, or even atypical mania or mood dysregulation, may serve as exemplars for understanding this extraordinary group of offenders. © 2017 American Academy of Psychiatry and the Law.

To examine the criminological circumstances of homicide in a group of French murderers with and without major mental disorders (MMD) stratified by the perpetrator's gender. Sociodemographic, clinical, and criminological variables were collected from the psychiatric expert reports of 210 cases of homicide heard at the High Court of Angers, France. Murderers were categorized according to MMD diagnosis and gender. Among 210 murderers, 17.6% (n = 37) had a MMD (20% of the female perpetrators). Logistic regression models showed that being a murderer with a MMD was associated with younger age (adjusted Odds Ratio OR = 1.03, P = 0.034), high school education (OR = 2.48, P = 0.036), previous use of psychiatric services (OR = 4.75, P = 0.003), alcohol intoxication (OR = 2.71, P = 0.027), and delusional state (OR = 3.96, P = 0.002) at the time of the homicide. Multiple correspondence analyses showed that female murderers with a MMD were more prone to have depression and to use drowning as a method than those without a MMD, and that male murderers with a MMD more often had a high school education and delusional beliefs at the time of the homicide than those without a MMD. Specific profiles of criminological circumstances of homicide could help to explore the risk of homicide in female and male patients with a MMD.

Crime is an ubiquitous part of society. The way people express their concerns about crimes has been of particular interest to the scientific community. Over time, the numbers and kinds of available communication channels have increased. Today, social media services, such Twitter, present a convenient way to express opinions and concerns about crimes. The main objective of this study is to explore people's perception of homicides, specifically, how the characteristics and proximity of the event affect the public's concern about it. The analysis explores Twitter messages that refer to homicides that occurred in London in 2012. In particular, the dependence of tweeting propensity on the proximity, in space and time, of a crime incident and of people being concerned about that particular incident are examined. Furthermore, the crime characteristics of the homicides are analysed using logistic regression analysis. The results show that the proximity of the Twitter users' estimated home locations to the homicides' locations impacts on whether the associated crime news is spread or not and how quickly. More than half of the homicide related tweets are sent within the first week and the majority of them are sent within a month of the incident's occurrence. Certain crime characteristics, including the presence of a knife, a young victim, a British victim, or a homicide committed by a gang are predictors of the crime-tweets posting frequency.

Psychocultural Mechanisms of the Propensity toward Criminal Homicide: A Multidimensional View of the Culture of Honor

PubMed Central

Souza, Monica G. T. C.; Souza, Bruno C.; Roazzi, Antonio; da Silva, Edson S.

2017-01-01

Introduction: Theory of the Culture of Honor is one of the few models in criminology specifically geared toward homicide. It proposes that, in certain societies, men must never show weakness and are required to react violently to any perceived threats to their reputation, thereby increasing their probability of committing a homicide. This has been suggested as the main explanation for the high rates of this type of crime in Brazil, particularly in the Northeast. Underlying this explanation there are complex mechanisms and processes that have yet to be clarified. Objectives: The present research aimed to investigate the workings of the possible psychocultural mechanisms underlying the culture of honor and the process through which they might affect the individual propensity toward homicide. Methods: A total of 336 Brazilian adults were assessed regarding a broad range of sociodemographic, psychological, and sociocultural variables, including their attitudes toward homicide. The resulting dataset was analyzed using Smallest Space Analysis and Facet Theory. Results: It seems that certain cultural elements associated to traditional masculinity and enhanced anger tend to promote negative personality traits and increase one’s propensity toward committing homicide. Conclusion: The findings obtained not only confirm the Theory of the Culture of Honor for the propensity toward homicide, but also explicit and clarify some of the psychocultural processes and mechanisms involved, suggesting a new scientific framework.

Racial disparities in age at time of homicide victimization: a test of the multiple disadvantage model.

PubMed

Lo, Celia C; Howell, Rebecca J; Cheng, Tyrone C

2015-01-01

This study sought the factors associated with race/ethnicity disparities in the age at which homicide deaths tend to occur. We used the multiple disadvantage model to take race into account as we evaluated associations between age at time of homicide victimization and several social structural, mental health-related, and lifestyle factors. Data were derived from the 1993 National Mortality Followback Survey, a cross-sectional interview study of spouses, next of kin, other relatives, and close friends of individuals 15 years and older who died in the United States in 1993. Our results showed age at time of homicide mortality to be related to the three types of factors; race moderated some of these relationships. In general, being employed, married, and a homeowner appeared associated with reduced victimization while young. The relationship of victimization age and employment was not uniform across racial groups, nor was the relationship of victimization age and marital status uniform across groups. Among Blacks, using mental health services was associated with longer life. Homicide by firearm proved important for our Black and Hispanic subsamples, while among Whites, alcohol's involvement in homicide exerted significant effects. Our results suggest that programs and policies serving the various racial/ethnic groups can alleviate multiple disadvantages relevant in homicide victimization at an early age. © The Author(s) 2014.

Direction, site and the muzzle target distance of bullet in the head and neck at close range as an indication of suicide or homicide.

PubMed

Suwanjutha, T

1988-05-01

Direction, site and muzzle target distance can indicate suicide or homicide. This conclusion can be drawn from autopsies of 57 cases of suicide and 68 cases of homicide by handgun fired at close range to the head and neck together with going to the crimescene in some cases. This study was carried out in Bangkok during the period from January 1983 to January 1986. In order to determine whether it was suicide or homicide, the path of the bullet, the site, the muzzle target distance must be considered. The angle of the bullet would be either elevated (from below upward), horizontal or an angle of depression (from above downward). For suicide, the direction of the bullet should be at an angle of elevation in the majority of cases. The position of the handgun in relation to the head in suicide was most often in tight contact and near contact. For homicide, the direction of the bullet should be horizontal in most cases. The bullet was at close range in the majority of the cases. There are 8 common sites for suicide and homicide and 10 different sites in the case of homicide which are at neck, left cheek, left aural region, lip, left occipital area orbit, chin, left eyebrow, submental and nose.

Violence is a significant public health problem. Thus, so as to prevent this problem, homicide, the severest form of violence depriving a human being of his right to live, deserves a detailed examination. This study is a retrospective research examining the 2951 cases of medicolegal autopsies in Adana during a period of 5 years (1997-2001). Among these cases, 620, which were determined to be homicidal, were taken into the scope of this study. The cases were examined with respect to sex, age groups, the method used during the act of homicide, the number and the localization of the wounds on the body. A total of 620 (21%) of the medicolegal autopsies conducted within this period were homicides. Of these cases, 515 (83.06%) were male and 105 (16.94%) female, and the rate of the males to females was 4.9; 72.74% of the victims were between the ages of 21 and 50. It was seen that 54.83% of the homicides involved firearms, while 35.16% of the victims were stabbed to death with a cutting object. It was also determined that the victims suffered a single wound in 47.35% of firearm-related murders and 29.35% of stabbings resulted in death. Alcohol was found in the blood of 7.58% of the homicide victims, while none had any illicit drugs.

In England and Wales, females are more prone to commit suicide than homicide. Homicidal offenders are more likely to victimize members of their own families and decidedly more prone to kill themselves. These tendencies are tentatively related to the possible development of a subculture of self-directed violence. (Author)

Firearm laws in one state may be associated with increased firearm death rates from homicide and suicide in neighboring states are uncertain. To determine whether counties located closer to states with lenient firearm policies have higher firearm death rates. This cross-sectional study of firearm death rates by county for January 2010 to December 2014 examined data from the US Centers for Disease Control and Prevention for firearm suicide and homicide decedents for 3108 counties in the 48 contiguous states of the United States. Each county was assigned 2 scores, a state policy score (range, 0-12) based on the strength of its state firearm laws, and an interstate policy score (range, -1.33 to 8.31) based on the sum of population-weighted and distance-decayed policy scores for all other states. Counties were divided into those with low, medium, and high home state and interstate policy scores. County-level rates of firearm, nonfirearm, and total homicide and suicide. With multilevel Bayesian spatial Poisson models, we generated incidence rate ratios (IRR) comparing incidence rates between each group of counties and the reference group, counties with high home state and high interstate policy scores. Stronger firearm laws in a state were associated with lower firearm suicide rates and lower overall suicide rates regardless of the strength of the other states' laws. Counties with low state scores had the highest rates of firearm suicide. Rates were similar across levels of interstate policy score (low: IRR, 1.34; 95% credible interval [CI], 1.11-1.65; medium: IRR, 1.36, (95% CI, 1.15-1.65; and high: IRR, 1.43; 95% CI, 1.20-1.73). Counties with low state and low or medium interstate policy scores had the highest rates of firearm homicide. Counties with low home state and interstate scores had higher firearm homicide rates (IRR, 1.38; 95% CI, 1.02-1.88) and overall homicide rates (IRR, 1.32; 95% CI, 1.03-1.67). Counties in states with low firearm policy scores had lower rates of firearm homicide only if the interstate firearm policy score was high. Strong state firearm policies were associated with lower suicide rates regardless of other states' laws. Strong policies were associated with lower homicide rates, and strong interstate policies were also associated with lower homicide rates, where home state policies were permissive. Strengthening state firearm policies may prevent firearm suicide and homicide, with benefits that may extend beyond state lines.

IMPORTANCE Homicide is a leading cause of adolescent mortality. To our knowledge, relatively little has been studied in terms of the association between environmental neighborhood features, such as streets, buildings, and natural surroundings, and severe violent injury among youth. OBJECTIVE To assess associations between environmental neighborhood features and adolescent homicide in order to identify targets for future place-based interventions. DESIGN, SETTING, AND PARTICIPANTS Population-based case-control study conducted in Philadelphia, Pennsylvania, from April 15, 2008, to March 31, 2014. We identified adolescents who died by homicide at 13 to 20 years of age from 2010 to 2012 while residing in Philadelphia. We used incidence-density sampling and random-digit dialing to recruit control participants ages 13 to 20 years matched on sex and indoor-outdoor location at the time of each index case participant’s homicide. EXPOSURES To obtain environmental data about modifiable features that were present in the immediate surroundings of our case and control participants, blinded field researchers used standardized techniques to photograph case and control participant outdoor locations. Photographic data were stitched together to create 360° panoramic images that were coded for 60 elements of the visible environment. MAIN OUTCOME AND MEASURE Adolescent homicide. RESULTS We enrolled 143 homicide case participants (mean [SD] age, 18.4 [1.5] years) and 155 matched control participants (mean [SD] age, 17.2 [2.1] years) who were both outdoors at the time of the homicide. In adjusted analyses, multiple features of Philadelphia streets, buildings, and natural surroundings were associated with adolescent homicide. The presence of street lighting (odds ratio [OR], 0.24; 95% CI, 0.09-0.70), illuminated walk/don’t walk signs (OR, 0.16; 95% CI, 0.03-0.92), painted marked crosswalks (OR, 0.17; 95% CI, 0.04-0.63), public transportation (OR, 0.13; 95% CI, 0.03-0.49), parks (OR, 0.09; 95% CI, 0.01-0.88), and maintained vacant lots (OR, 0.17; 95% CI, 0.03-0.81) were significantly associated with decreased odds of homicide. The odds of homicide were significantly higher in locations with stop signs (OR, 4.34; 95% CI, 1.40-13.45), security bars/gratings on houses (OR, 9.23; 95% CI, 2.45-34.80), and private bushes/plantings (OR, 3.44; 95% CI, 1.18-10.01). CONCLUSIONS AND RELEVANCE Using a population-based case-control design, we identified multiple modifiable environmental features that might be targeted in future randomized intervention trials designed to reduce youth violence by improving neighborhood context.

2002-01-01

To test whether relations between economic development, economic inequality, and child and youth homicide rates are sex- and age-specific, and whether a country's wealth modifies the impact of economic inequality on homicide rates. Outcome variables were homicide rates around 1994 in males and females in the age ranges 0-4, 5-9, 10-14, 15-19 and 20-24 years from 61 countries. Predictor variables were per capita gross domestic product (GDP), GINI coefficient, percentage change in per capita gross national product (GNP) and female economic activity as a percentage of male economic activity. Relations were analysed by ordinary least squares regression. All predictors explained significant variances in homicide rates in those aged 15-24. Associations were stronger for males than females and weak for children aged 0-9. Models that included female economic inequality and percentage change in GNP increased the effect in children aged 0-9 and the explained variance in females aged 20-24. For children aged 0-4, country clustering by income increased the explained variance for both sexes. For males aged 15-24, the association with economic inequality was strong in countries with low incomes and weak in those with high incomes. Relations between economic factors and child and youth homicide rates varied with age and sex. Interventions to target economic factors would have the strongest impact on rates of homicide in young adults and late adolescent males. In societies with high economic inequality, redistributing wealth without increasing per capita GDP would reduce homicide rates less than redistributions linked with overall economic development.

Violence-related firearm deaths among residents of metropolitan areas and cities---United States, 2006--2007.

PubMed

2011-05-13

Violence-related firearm deaths remain an important public health concern in the United States. During 2006--2007, a total of 25,423 firearm homicides and 34,235 firearm suicides occurred among U.S. residents. These national totals include 4,166 firearm homicides and 1,446 firearm suicides among youths aged 10--19 years; the rate of firearm homicides among youths slightly exceeded the rate among persons of all ages. This report presents statistics on firearm homicides and firearm suicides for major metropolitan areas and cities, with an emphasis on youths aged 10--19 years in recognition of the importance of early prevention efforts. It integrates analyses conducted by CDC in response to requests for detailed information, arising from a heightened focus on urban violence by the media, the public, and policymakers over the past year. Firearm homicides and suicides and annual rates were tabulated for the 50 largest U.S. metropolitan statistical areas (MSAs) and their central cities for 2006--2007, using data from the National Vital Statistics System and the U.S. Census Bureau. Firearm homicide rates in approximately two thirds of the MSAs exceeded the national rate, and 86% of cities had rates higher than those of their MSAs. The youth firearm homicide rate exceeded the all-ages rate in 80% of the MSAs and in 88% of the cities. Firearm suicide rates in just over half of the MSAs were below the national rate, and 55% of cities had rates below those of their MSAs. Youth firearm suicide rates in the MSAs and cities were collectively low compared with all-ages rates. Such variations in firearm homicide and firearm suicide rates, with respect to both urbanization and age, should be considered in the continuing development of prevention programs directed at reducing firearm violence.

Do black lives matter in public health research and training?

To examine whether investments made in public health research align with the health burdens experienced by white and black Americans. In this cross-sectional study of all deaths in the United States in 2015, we compared the distribution of potential years of life lost (PYLL) across 39 causes of death by race and identified key differences. We examined the relationship between cause-of-death-specific PYLL and key indicators of public health investment (federal funding and number of publications) by race using linear spline models. We also compared the number of courses available at the top schools of public health relevant to the top causes of death contributor to PYLL for black and white Americans. Homicide was the number one contributor to PYLL among black Americans, while ischemic heart disease was the number one contributor to PYLL among white Americans. Firearm-related violence accounted for 88% of black PYLL attributed to homicide and 71% of white PYLL attributed to homicide. Despite the high burden of PYLL, homicide research was the focus of few federal grants or publications. In comparison, ischemic heart disease garnered 341 grants and 594 publications. The number of public health courses available relevant to homicide (n = 9) was similar to those relevant to ischemic heart disease (n = 10). Black Americans are disproportionately affected by homicide, compared to white Americans. For both black and white Americans, the majority of PYLL due to homicide are firearm-related. Yet, homicide research is dramatically underrepresented in public health research investments in terms of grant funding and publications, despite available public health training opportunities. If left unchecked, the observed disproportionate distribution of investments in public health resources threatens to perpetuate a system that disadvantages black Americans.

As most developing countries, including Nigeria, grapple with economic crisis, poor human capital development and high levels of income inequality, violent crimes - especially homicides - continue to be a cause for concern. We studied the pathology and demographic distribution of homicides in Rivers State of Nigeria expecting that the findings would be useful in formulating preventive strategies. Reports of homicide autopsies in the state for 11 years were retrospectively scrutinized for age, gender, type of weapon, site of injury, circumstances, mechanisms and causes of death. The data were analyzed using SPSS version 17. Homicides constituted 50.5% of the medicolegal autopsies. Although the overall male:female ratio was 12.4 : 1, there was variation with weapon. Deaths by firearm had the highest male:female ratio of 24.6 : 1. The mean and peak ages were 29.2 ± 11.4 and 21-30 years, respectively, while the range was 1 to 96 years. Firearms were the most common weapons, at 68.9%, hemorrhagic shock and head injuries at 61.5% and 28.2% respectively were the most common mechanisms and causes of death. Armed robbery incidents were the most common circumstances, while the head was the most common site of injury at 48.8%. The homicide rate is high in our environment and most homicides are committed during armed robberies using firearms. Improving medical care and providing emergency medical services will reduce cases of deaths from homicides, most of which occur due to manageable hemorrhagic shock. Increasing the drive towards controlling illegal arms acquisition and possession will reduce the present carnage in the state.

This study aims to describe the circumstances in which older people commit homicide, the form of assessment they undergo and to examine the proportion of those who suffer from mental illness. The study was carried out as part of the England and Wales National Confidential Inquiry into Suicide and Homicide by People with Mental Illness based on a five-year sample. The Inquiry was notified of the names of those over the age of 60 years convicted of homicide and also the details of the offence, sentencing and outcome in court by the Home Office. The Inquiry collected clinical data of those known to have had contact with mental health services from the responsible service and also retrieved psychiatric reports of those convicted. Homicide incidents perpetrated by older people typically involve a man killing his partner in an impulsive manner. The most common method was by using a sharp instrument (34%), followed by the use of a blunt instrument (26%). The use of firearms was rare (11%). Perpetrators aged 65 years and older were significantly more likely to kill a current or former spouse/partner and less likely to kill an acquaintance. Forty-four per cent of perpetrators over 65 years old suffered from depression at the time of the offence, whereas rates of schizophrenia and alcohol dependence were low. The information used in the study was extracted from a unique national database of homicide perpetrators. The characteristics and the circumstances of homicides perpetrated by older people are different to other age groups. An older-people homicide may be preventable if depression is identified early in older people. Copyright © 2012 John Wiley & Sons, Ltd.

A population-based case-control study was conducted to assess the relationship between genocide exposure and homicide perpetration in Rwanda. A sample of 150 homicide perpetrators who were charged with and confessed to having committed homicide between 1 May 2011 and 31 May 2013 and 450 controls were enrolled. Cases were matched to controls by neighborhood, age and sex. Socio-demographic, background and genocide-related information was collected from study subjects' next of kin. Four characteristics of genocide exposure were: genocide survivor, genocide perpetrator, having lost a first-degree relative to genocide and having a first-degree relative convicted of genocide. We assessed the impact of each genocide-exposure variable using conditional logistic regression. Of the 150 cases, 124 (82.7%) were male and 26 (17.3%) were female. The mean age of the alleged homicide perpetrators was 33 years, with a peak in the age group 20-29 years (39.3%). After adjusting for socio-demographic characteristics and past common criminal records, having a first-degree relative who had been convicted of genocide crimes was a significant predictor for homicide perpetration (odds ratio [OR] = 14.4, 95% confidence interval [CI] = 1.6-129.4). Being a genocide perpetrator, a genocide survivor and having lost a first-degree family member to genocide were not identified as risk factors for homicide perpetration. In Rwanda, young people who experienced early exposure to trauma by witnessing their first-degree relatives' active participation in the genocide, are more likely to commit homicide. Socio-economic and psychotherapeutic programs targeting this population group are needed to rehabilitate these young people for violent behavior change.

Social disorganization and homicide mortality rate trajectories in Brazil between 1991 and 2010.

Peres, Maria Fernanda Tourinho; Nivette, Amy

2017-10-01

Since the 1990s, researchers have noted declining trends in crime and violence, particularly homicide, in Western countries. Studies have explored national and sub-national trends using latent trajectory analysis techniques and identified several factors associated with declining and/or increasing trajectories. Social disorganization (SD) has been consistently linked to increases in homicide rates over time, explaining at least some of the spatial and temporal heterogeneity of homicide. Similar studies have not yet been carried out in Latin America's cities. In this paper we use Group Based Trajectory models to study homicide mortality rate [HMR] trajectories in Brazilian municipalities between 1991 and 2010. Then, through binary and multinomial logistic regression we investigated the association between SD in 1991, and the likelihood of an increasing HMR trajectory. We carried out an ecological time series study using all Brazilian municipalities in the period between 1991 and 2010 (n = 4491). Data on homicide deaths were collected from the Mortality Information System of the Ministry of Health and standardized by age to calculate HMR per 100,000 population. Socioeconomic and demographic data for 1991 were used to compose the composite measure of SD. Our results highlight the spatial and temporal heterogeneity of homicide mortality in Brazilian municipalities. While national trends are steadily increasing, disaggregating municipal trajectories shows that this is driven by a small proportion of municipalities in the country. We found that SD is associated with an ascending homicide trajectory. This result generally supports the notion that poor social structural conditions can create 'space' for criminal behavior and groups and, consequently, violent death. Copyright © 2017 Elsevier Ltd.

Variations in wounding by relationship intimacy in homicide cases.

PubMed

Trojan, Carrie; Krull, Amy C

2012-09-01

There are numerous examples in the homicide literature of a presumed connection between the victim-offender relationship and the manner, extent, and body location of wounds inflicted in homicides. The current study examined variations in wounding patterns according to the intimacy of the victim-offender relationship in a sample of urban homicides to explore the investigative utility of this information in an average homicide event. The findings demonstrated that victims who had a current or former intimate relationship with their offender were more likely to receive wounds to the face and be injured with a weapon from the scene compared with all other relationship groups, whereas injury to the head and use of manual violence were more likely among intimates and family/friends compared with acquaintances or strangers. However, the groups did not significantly differ in terms of the overall amount of wounds inflicted. Implications of the findings and suggested areas of future research are discussed.

To analyze the association between police violence and homicide mortality rates taking into consideration the effect of contextual variables. This was an environmental, cross-sectional study that included the 96 census districts in the City of São Paulo. The association between the variables was analyzed using Spearman's rank correlation and simple and multiple regression analysis. Univariate analysis revealed a strong and significant association between homicide mortality coefficients and all the indicators of socioeconomic development and police violence. After controlling for potential confounding factors, the association between police violence and homicide mortality coefficients remained strong and significant. This significance was lost only after control for the size of the resident population. The results indicate that police action that violates basic human rights is not the right answer to urban violence. The combination of homicides from interpersonal violence and deaths from police violence results in negative socialization and promotes further violence.

Criminal recidivism in sexual homicide perpetrators.

Hill, Andreas; Habermann, Niels; Klusmann, Dietrich; Berner, Wolfgang; Briken, Peer

2008-02-01

Forensic psychiatric reports on 166 sexual homicide perpetrators in Germany were retrospectively analyzed for criminal risk factors. Follow-up information about release and reconvictions from federal criminal records was available for 139 offenders; 90 (64.7%) had been released. The estimated recidivism rate (Kaplan-Meier analyses) for 20 years at risk was 23.1% for sexual and 18.3% for nonsexual violent reoffences. Three men (3.3%) were reconvicted for attempted or completed homicide. Only young age at the time of sexual homicide resulted in higher sexual recidivism, whereas increased nonsexual violent recidivism was related to previous sexual and nonsexual delinquency, psychopathic symptoms, and higher scores in risk assessment instruments. Increased recidivism with any violent reoffence was associated with age-related factors: young age at first sexual offence, at homicide, and at release and duration of detention. The impacts of the results for risk assessment, relapse prevention, and supervision are discussed.

Over the course of the past 30 years, Brazil has experienced an exponential increase in its homicide rates, which is a problem that has been aggravated by the slaughter of young nonwhite, poor, males living in the shantytowns and communities. Given the complexity and the resurgence of the homicide phenomenon in Brazil, this article seeks to discuss some of the main effects that these trends have had on investigative police work. For this purpose, a long process of ethnographic research in six Specialized Homicide Police Units of Belo Horizonte (BH) was conducted between the years 2009 and 2010. During this period, researchers accompanied the daily routine of these units and conducted several in-depth interviews with investigators and civil police chiefs. Among the results, the mismatch between the increasing complexity of the homicide phenomenon and the legal procedures established for investigating the problem in BH should be stressed.

Intimate Partner Violence: A Rare Case of Reciprocal Homicide.

2017-06-01

We present the case of a reciprocal homicide by stabbing that occurred within an unmarried couple without known history of spousal violence. Each partner killed the other one at the same time and at the same place using kitchen knives. They were both found dead at home lying on the floor after the neighbors heard an argument and screams coming from the couple's apartment, so they called the police and the fire department. The door was locked from the inside, and the fire department was forced to break the door. Two kitchen knives supporting blood traces were found at the scene. At autopsy, both bodies showed multiple stab wounds, and the lethal ones were due to heart injuries. Defense injuries were also found in both bodies. To our knowledge, this is the first case of reciprocal homicide described in the literature. Other manners of death are discussed, including homicide by a third party, homicide-suicide, and suicide pact.

Perpetrators of spousal homicide: a review.

Aldridge, Mari L; Browne, Kevin D

2003-07-01

It has been argued that individuals who engage in spouse abuse increase their violence toward their partners, which can culminate in the death of either the assaulter or the victim. The aim of this review is to identify risk factors that determine whether an abusive relationship will end in eventual death. An extensive search revealed 22 empirical research studies on risk factors for spousal homicide. The circumstances of spousal homicide are described and salient risk factors are highlighted. In the United Kingdom, 37% of all women were murdered by their current or former intimate partner compared to 6% of men. The most common cause of an intimate partner's death in England and Wales was being attacked with a sharp implement or being strangled. By contrast, the most common cause in the United States for spousal homicide was being shot. Nine major risk factors are found that may help predict the probability of a partner homicide and prevent future victims.

Rates of Household Firearm Ownership and Homicide Across US Regions and States, 1988–1997

Objectives. In this study we explored the association between rates of household firearm ownership and homicide across the United States, by age groups. Methods. We used cross-sectional time-series data (1988–1997) to estimate the association between rates of household firearm ownership and homicide. Results. In region- and state-level analyses, a robust association between rates of household firearm ownership and homicide was found. Regionally, the association exists for victims aged 5 to 14 years and those 35 years and older. At the state level, the association exists for every age group over age 5, even after controlling for poverty, urbanization, unemployment, alcohol consumption, and nonlethal violent crime. Conclusions. Although our study cannot determine causation, we found that in areas where household firearm ownership rates were higher, a disproportionately large number of people died from homicide.

A cross-national study of the association between natural resource rents and homicide rates, 2000–12

Countries that rely on natural resource rents (that is, the revenue generated from the sale of natural resources) may suffer from a variety of social problems. This exploratory study reviews the natural resource extraction literature to derive a ‘natural resource rents–homicide’ hypothesis. Data for 173 countries for the years 2000 to 2012 are examined to determine if there is a correlation between natural resource rents and homicide rates. Multilevel growth models suggest that natural resource rents are positively correlated with homicide rates within countries (level 1) but not between them (level 2). Importantly, the correlation between natural resource rents and homicide is strongest when natural resource rents are lagged. We conclude by suggesting that increasing natural resource rents may be counterproductive over the long run and sow the seeds for a future increase in homicide. PMID:28781581

2015-01-01

The disproportionate representation of African American survivors of homicide victims places them at greater risk for compromised mental health. However, an examination of factors that influence how this population copes with this traumatic event is absent from the literature. This article elucidates the importance of sociocultural factors that influence coping resources and strategies for African Americans surviving the homicide of a loved one. A socioculturally responsive model of coping is presented that can be utilized in furthering the development of research and practice that is culturally responsive to the needs of African American survivors of homicide victims. © The Author(s) 2013.

This article examines the complexity of street gang homicides and focuses on situational factors that lead to gang members’ susceptibility to this violent behavior within the context of a disadvantaged minority community. This study is based on an analysis of 28 homicides involving Mexican American gang members. The absence of immigrant youth involvement in these types of violent crimes is discussed. Findings demonstrate how locally embedded social processes associated with specific gang types, ecology, drugs, circumstances, and motives unfold into homicidal events. These findings may contribute to the development of street-based social programs focused on gang mediation, dispute resolution, and crisis intervention. PMID:21218188

This study reviews firearm-related deaths (homicidal, suicidal and accidental) from 1994 to 2003 in the Western Sidney area, Australia, serviced by the Westmead Department of Forensic Medicine, in order to document the features of the cases and to assess the effect of the introduction of the NSW Firearms Act in 1996. There were 211 fatalities involving firearms (1.8% of all of the Coroner's cases for the period); firearm deaths were classified as homicide (75), suicide (134) or accidental (2). There was a clear peak of homicide deaths by firearm in the 20-29 age group, whereas the suicide peak was broad, spanning the ages 20-69 years. More suicides occurred at home than homicides and a higher proportion of suicides were by rifle than homicides, which favoured hand guns. Entry wounds in suicides mostly involved the head, with the chest being the commonest entry site in homicides. The only statistically significant trend was for an increase in the number of firearm-related suicides in males, comparing the number of deaths pre- and post-firearm law introduction. The study includes reports of two suicides by unusual weapons: a home-made pipe gun and a spear gun.

Determining the relationship between gun ownership levels and firearm homicide rates is critical to inform public health policy. Previous research has shown that state-level gun ownership, as measured by a widely used proxy, is positively associated with firearm homicide rates. A newly developed proxy measure that incorporates the hunting license rate in addition to the proportion of firearm suicides correlates more highly with state-level gun ownership. To corroborate previous research, we used this new proxy to estimate the association of state-level gun ownership with total, firearm, and non-firearm homicides. Using state-specific data for the years 1981-2010, we modelled these rates as a function of gun ownership level, controlling for potential confounding factors. We used a negative binomial regression model and accounted for clustering of observations among states. We found that state-level gun ownership as measured by the new proxy, is significantly associated with firearm and total homicides but not with non-firearm homicides.

2005-01-01

To describe the epidemiology of violent deaths (suicides and homicides) of children and youth in Wisconsin. Linked data from death certificates, coroners or medical examiners, Uniform Crime Reports, police case reports and crime laboratories were analyzed using SPSS 11.5. Analyses from 2000 to 2002 describe suicides and homicides of children and youth under age 25. Rates are per 100,000 population per year. A total of 585 persons under age 25 in Wisconsin died from suicide or homicide during 2000--2002. Suicides outnumbered homicides 323 (55%) to 262 (45%). Firearms were involved in 59% (n=344) of cases. Fatality rates increased with advancing age, ranging from 2.0 in 0-13 year olds to 26.9 in youth age 21-24. There were over twice as many violent deaths compared to cancer and infectious disease deaths combined (n=253). Suicides and homicides are a significant burden on the children and youth of Wisconsin. An investment in reducing this burden requires comprehensive data and informed programs and policies. We recommend that physicians and public health community leaders collaborate with the criminal justice community and policy makers to develop, implement, and evaluate prevention programs and policies.

International correlations between gun ownership and rates of homicide and suicide.

Killias, M

1993-01-01

OBJECTIVE: To examine international correlations between reported rates of household gun ownership and rates of homicide and suicide with a gun. DESIGN: Survey. POPULATION: People who responded to a telephone survey conducted by the 1989 International Crime Survey in 11 European countries, Australia, Canada and the United States. RESULTS: Positive correlations were obtained between the rates of household gun ownership and the national rates of homicide and suicide as well as the proportions of homicides and suicides committed with a gun. There was no negative correlation between the rates of ownership and the rates of homicide and suicide committed by other means; this indicated that the other means were not used to "compensate" for the absence of guns in countries with a lower rate of gun ownership. CONCLUSION: Larger studies are needed to examine more closely possible confounding factors such as the national tendency toward violent solutions, and more information on the type and availability of guns will be helpful in future studies. Nevertheless, the correlations detected in this study suggest that the presence of a gun in the home increases the likelihood of homicide or suicide. PMID:8485675

Post-incarceration Recidivism of Lone versus Group Juvenile Homicide Offenders.

2016-11-01

Killings by juvenile homicide offenders (JHOs) who use accomplices have been increasing since the 1980s and currently represent approximately half of juvenile arrests for murder in the United States. Nevertheless, prior research has not compared JHOs who kill alone with JHOs who kill in groups. The present research followed up 30 years later on a sample of 59 male murderers and attempted murderers sentenced to adult prison. This study was designed to analyze whether lone and group JHOs differed on pre-incarceration, incarceration, and post-incarceration variables. Significant findings indicated that compared with lone offenders, group JHOs had a higher mean of pre-homicide arrests and were more likely to be Black, have a pre-homicide delinquent record, commit a crime-related homicide offense, and target a stranger. With respect to post-homicide variables, group JHOs were more likely to be released from prison and more likely to be rearrested. The two types of JHOs did not differ significantly in relation to the number of post-release violent offenses. Preliminary implications of the findings and avenues for future investigation are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Can Intoxication Status Be Used as a Prediction Tool for Manner of Death?: A Comparison of the Intoxication Status in Violent Suicides and Homicides.

2017-03-01

Determining the manner of death in medicolegal death investigations can be difficult. The investigator relies on many facets of death investigation, including the circumstances of death and autopsy examination. A study was designed to analyze whether the intoxication status of the decedent could be used as another tool in death investigations. The intoxication status of violent (nonoverdose or poisoning) suicides and homicides was retrospectively reviewed and compared. A total of 625 deaths were identified, including 366 suicides and 259 homicides. Age, sex, cause of death, and intoxication status, including the specific drugs present, were analyzed. Gunshot wounds were the most common cause of death in both groups, with hanging being the second most common cause in suicides and sharp force injuries in homicides. Analysis found that although the overall intoxication status for suicides versus homicides did not differ significantly, certain drugs were more prevalent in one group over the other. Specifically, illicit drugs, that is, heroin, cocaine, and methamphetamine, were more likely to be present in homicides, whereas antidepressants or antipsychotics, benzodiazepines, and zolpidem were more common in suicides.

Adverse Childhood Experiences and Criminal Extremity: New Evidence for Sexual Homicide.

DeLisi, Matt; Beauregard, Eric

2018-03-01

Adverse childhood experiences are associated with a wide range of behavioral, health, and psychiatric deficits and have recently been used to study the development of serious offending careers. Unfortunately, this research paradigm has largely ignored forensic populations. This study utilized the adverse childhood experiences framework to examine the associations between exposure to violence, victimization, and total adverse childhood experiences on sexual homicide using a sample of 616 incarcerated adult male sexual offenders from Canada 85 of whom committed sexual homicide. Epidemiological tables of odds revealed that a gradient of adverse childhood experiences was associated with sexual homicide, but that the most significant risks were for offenders who had the most extensive abuse histories. In adjusted models, exposure to violence, victimization, and total adverse childhood experiences increased the odds of sexual homicide by 334%, 249%, and 546%, respectively. These effects intensified in models adjusted for childhood enuresis, cruelty to animals, parental abandonment, deviant sexual behaviors, poor self-image, and sexual problems to 559%, 326%, and 849%, respectively. The adverse childhood experiences framework is a systematic way to organize the criminogenic developmental sequela in sexual homicide. © 2017 American Academy of Forensic Sciences.

Parasite stress promotes homicide and child maltreatment

PubMed Central

Thornhill, Randy; Fincher, Corey L.

2011-01-01

Researchers using the parasite-stress theory of human values have discovered many cross-cultural behavioural patterns that inform a range of scholarly disciplines. Here, we apply the theory to major categories of interpersonal violence, and the empirical findings are supportive. We hypothesize that the collectivism evoked by high parasite stress is a cause of adult-on-adult interpersonal violence. Across the US states, parasite stress and collectivism each positively predicts rates of men's and women's slaying of a romantic partner, as well as the rate of male-honour homicide and of the motivationally similar felony-related homicide. Of these four types of homicide, wealth inequality has an independent effect only on rates of male-honour and felony-related homicide. Parasite stress and collectivism also positively predict cross-national homicide rates. Child maltreatment by caretakers is caused, in part, by divestment in offspring of low phenotypic quality, and high parasite stress produces more such offspring than low parasite stress. Rates of each of two categories of the child maltreatment—lethal and non-lethal—across the US states are predicted positively by parasite stress, with wealth inequality and collectivism having limited effects. Parasite stress may be the strongest predictor of interpersonal violence to date. PMID:22042922

Gaps in Crisis Mental Health: Suicide and Homicide-Suicide.

PubMed

Carretta, Carrie M; Burgess, Ann W; Welner, Michael

2015-10-01

Gaps in crises of mental health emerge from poor distinction between the qualities of people who suicide and those who murder and then kill themselves. The role, if any, that substance use has in such lethal violence is an example of such a lack of distinction. In this study, a sample of medical examiner investigative and toxicology reports from Los Angeles and Orange counties in California were available for analysis for 432 suicide cases and 193 homicide-suicide cases. This informed clearer toxicological and pharmacological distinction of suicide from homicide-suicide. Blood alcohol levels were higher in persons committing suicide than in homicide-suicide perpetrators (p=.004). Homicide-suicide perpetrators had almost twice the level of stimulants in their system than people who suicide (p=.022) but did not have comparatively elevated levels of drugs or alcohol. Predictors of suicide included the following: substance abuse history, high number of drugs in system, death inside a house, and legal impairment by alcohol. Predictors of homicide-suicide included gunshot as the cause of death, female gender, domestic conflict, children living in the home, and prior arrest for substance abuse.

Background Death is the most extreme consequence of intimate partner violence. Female homicide studies with data on the perpetrator–victim relationship can provide insights. We compare the results of two South African national studies of female homicide with similar sampling done 10 y apart. Methods and Findings We conducted a retrospective national survey using a weighted cluster design of a proportionate random sample of 38 mortuaries to identify homicides committed in 2009. We abstracted victim data from mortuary and autopsy reports, and perpetrator data from police interviews. We compared homicides of women 14 y and older in 2009 with previously published data collected with the same methodology for homicides committed in 1999. The study found that the rate of female homicide per 100,000 female population in 2009 was 12.9 (95% confidence interval [CI]: 9.3, 16.5), compared to 24.7 (95% CI: 17.7, 31.6) in 1999. The incidence rate ratio of 0.54 (95% CI: 0.20, 0.84) reflects a significantly lower rate in 2009. The rate of intimate partner femicide was 5.6/100,000 in 2009 versus 8.8/100,000 in 1999, with an incidence rate ratio of 0.63 (95% CI: 0.24, 1.02), indicating no difference between rates. Logistic regression analysis of homicide characteristics showed that the odds ratio of suspected rape among non-intimate femicides in 2009 compared to 1999 was 2.61 (95% CI: 1.23, 4.08) and among intimate partner femicides it was 0.84 (95% CI: 0.50, 1.42). The OR of homicide by gunshot was 0.54 (95% CI: 0.30, 0.99) in 2009 versus 1999. There was a significant drop in convictions of perpetrators of non-intimate femicide in 2009 versus 1999 (OR = 0.32 [95% CI: 0.19, 0.53]). Limitations of the study include the relatively small sample size and having only two time points. Conclusions Female homicide in South Africa was lower in 2009 than 1999, but intimate partner femicide and suspected rape homicide rates were not statistically different. The cause of the difference is unknown. The findings suggest that South Africa needs greater efforts nationally to implement evidence-based violence prevention.

Non-serious offenses in manic phase have been mainly studied in patients with bipolar disorder. However, some authors reported that depressive phase is related with the violent and homicidal manifestations of bipolar disorder. We investigated the characteristics of homicide by the polarity of mood episode in patients with bipolar I disorder. Among the offenders who were sentenced to undergo treatment at the National Institute of Forensic Psychiatry from October 1987 to January 2008, a total 219 offenders whose final diagnoses were bipolar I disorder based on DSM-III-R and DSM-IV were selected. Retrospective medical chart review was performed for characteristics of mood episodes. Descriptions of offenders were supplemented by review of the written records of the police or prosecutors. The general rate of total offense was higher in the manic phase than in the depressive phase (86.8% vs. 13.2%). However, the rate of homicide was higher in the depressive phase than in the manic phase. The victims of homicide were more likely to be family members of the patients in depressive phase than in manic phases (96.2% vs. 63.9%, p=0.001). However, parricide was committed only in manic phases. Altruistic motivation of homicide was significantly higher in depressive phase (34.6% vs. 0%, p<0.001) whereas impulsivity was the most common one in manic phases. The risk of offenses, particularly homicide for family members, should not be overlooked in the depressive phases of bipolar I disorder. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Revenge and psychological adjustment after homicidal loss.

Feelings of revenge are a common human response to being hurt by others. Among crime victims of severe sexual or physical violence, significant correlations have been reported between revenge and Posttraumatic Stress Disorder (PTSD). Homicide is one of the most severe forms of interpersonal violence. It is therefore likely that individuals bereaved by homicide experience high levels of revenge, which may hamper efforts to cope with traumatic loss. The relationship between revenge and psychological adjustment following homicidal loss has not yet been empirically examined. In the current cross-sectional study, we used self-report data from 331 spouses, family members and friends of homicide victims to examine the relationships between dispositional revenge and situational revenge on the one hand and symptom-levels of PTSD and complicated grief, as well as indices of positive functioning, on the other hand. Furthermore, the association between revenge and socio-demographic and offense-related factors was examined. Participants were recruited from a governmental support organization, a website with information for homicidally bereaved individuals, and members of support groups. Levels of both dispositional and situational revenge were positively associated with symptoms of PTSD and complicated grief, and negatively with positive functioning. Participants reported significantly less situational revenge in cases where the perpetrator was a direct family member than cases where the perpetrator was an indirect family member, friend, or someone unknown. Homicidally bereaved individuals reported more situational revenge, but not more dispositional revenge than a sample of students who had experienced relatively mild interpersonal transgressions. © 2014 Wiley Periodicals, Inc.

It is generally considered that women who kill are more likely to have a psychiatric disorder than their male counterparts, but as a relatively small group, women are much less often studied than men in this context. To explore gender differences in the psychosocial history of homicide offenders. In this nationwide register-based study, data were extracted from the forensic psychiatric examination and crime reports of all 91 women prosecuted for homicide in Finland between 1995 and 2004 and from those of the next adjacent man convicted of a separate homicide (n = 91). Both female and male homicide offenders had a troubled childhood, but more women had witnessed or experienced family violence; more women had failed to complete their primary education. Men, however, were more likely to have had an offending history. Although there were no differences between the men and women in the frequencies of psychiatric diagnoses or of substance abuse, the women had more often received prior mental health treatment. The women were also more likely to have had a history of suicidal behaviour. Both female and male homicide offenders are a troubled group of people, with slightly different criminal careers. Many use mental health services and therefore prevention could be improved. The suggestion of a special sub-group of women characterised by early educational and behavioural difficulties needs replication, as it may have implications for service development.

To examine whether state-level spending on social and public health services is associated with lower rates of homicide in the USA. Ecological study. USA. All states in the USA and the District of Columbia for which data were available (n=42). Homicide rates for each state were abstracted from the US Department of Justice Federal Bureau of Investigation's Uniform Crime Reporting. After adjusting for potential confounding variables, we found that every $10 000 increase in spending per person living in poverty was associated with 0.87 fewer homicides per 100 000 population or approximately a 16% decrease in the average homicide rate (estimate=-0.87, SE=0.15, p<0.001). Furthermore, there was no significant effect in the quartile of states with the highest percentages of individuals living in poverty but significant effects in the quartiles of states with lower percentages of individuals living in poverty. Based on our findings, spending on social and public health services is associated with significantly lower homicide rates at the state level. Although we cannot infer causality from this research, such spending may provide promising avenues for homicide reduction in the USA, particularly among states with lower levels of poverty. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The scope of this study was to describe the magnitude and distribution of deaths by homicide in the Americas and to analyze the prevailing trends. Deaths by homicide (X85 to Y09 and Y35) were analyzed in 32 countries of the Americas Region from 1999 to 2009, recorded in the Mortality Information System/Pan American Health Organization. A negative binomial model was used to study the trends. There were around 121,297 homicides (89% men and 11% women) in the Americas, annually, predominantly in the 15 to 24 and 25 to 39 year age brackets. In 2009 the homicide age-adjusted mortality rate was 15.5/100,000 in the region. Countries with lower rates/100,000 were Canada (1.8), Argentina (4.4), Cuba (4.8), Chile (5.2), and the United States (5.8), whereas the highest rates/100,000 were in El Salvador (62.9), Guatemala (51.2), Colombia (42.5), Venezuela (33.2), and Puerto Rico (25.8). From 1999-2009, the homicide trend in the region was stable. They increased in nine countries: Venezuela (p<0.001), Panama (p<0.001), El Salvador (p<0.001), Puerto Rico (p<0.001); decreased in four countries, particularly in Colombia (p<0.001); and were stable in Brazil, the United States, Ecuador and Chile. The increase in Mexico occurred in recent years. Despite all efforts, various countries have high homicide rates and they are on the increase.

Sharp and blunt force trauma concealment by thermal alteration in homicides: An in-vitro experiment for methodology and protocol development in forensic anthropological analysis of burnt bones.

2017-06-01

Burning of human remains is one method used by perpetrators to conceal fatal trauma and expert opinions regarding the degree of skeletal evidence concealment are often disparate. This experiment aimed to reduce this incongruence in forensic anthropological interpretation of burned human remains and implicitly contribute to the development of research methodologies sufficiently robust to withstand forensic scrutiny in the courtroom. We have tested the influence of thermal alteration on pre-existing sharp and blunt trauma on twenty juvenile sheep radii in the laboratory using an automated impact testing system and an electric furnace. The testing conditions simulated a worst-case scenario where remains with pre-existing sharp or blunt trauma were exposed to burning with an intentional vehicular fire scenario in mind. All impact parameters as well as the burning conditions were based on those most commonly encountered in forensic cases and maintained constant throughout the experiment. The results have shown that signatures associated with sharp and blunt force trauma were not masked by heat exposure and highlights the potential for future standardization of fracture analysis in burned bone. Our results further emphasize the recommendation given by other experts on handling, processing and recording burned remains at the crime scene and mortuary. Copyright © 2017 Elsevier B.V.

Bony injuries in homicide cases (1994-2014). A retrospective study.

Even when human skeletal remains are found in contexts indicative of body disposal after homicide, none of the bones may manifest injuries. When skeletons are incomplete, there are two possibilities, the injured bones are missing or none were injured. This leads to the question how frequently bones are injured during homicide, where the injuries tend to be placed, and whether the frequency of injury is related to the type of homicide. To answer these questions, the postmortem reports from all autopsies performed for homicide victims at the Institute of Legal Medicine at the University Hospital in Frankfurt am Main, Germany, between 1994 and 2014, were retrospectively evaluated for bony injuries discovered during autopsy. In 90 cases, a preliminary postmortem computed tomography (pmCT) examination had been performed. The cases were categorized into the following five groups by type of fatal trauma: blunt force, sharp force, gunshot injury, strangulation, or other. In total, the postmortem reports for 897 homicides (527 male, 370 female) were evaluated. The number of victims per trauma category were sharp force, 309; blunt force, 179; gunshot injury, 242; strangulation, 92; and other, 75. Bony injuries had been reported in 70.9 % of the homicides. The "gunshot" category contained the highest proportion of victims with bony injuries (92.6 %). With 80.4 %, the second-highest proportion of victims with bony injuries was in the "blunt force" category, followed by 66.3 % of victims in the "sharp force" group. In contrast, with 53.3 %, the second-lowest proportion of victims with bony injuries was in the "strangulation" category, which contained a preponderance of female victims, followed by 17.3 % of victims with bony injuries in the "other" category. Bony injuries thus occurred in the majority of homicides. Forensic osteological analysis should, therefore, always be performed on badly decomposed human remains. Where necessary, the additional use of visualization techniques, in particular, pmCT, or maceration may be considered. The absence of bony injuries does not rule out homicide; e.g., in strangulations, bony injuries are manifest in only half the victims, even when the skeleton is intact. The relevant structures are also easily lost to decomposition, scavenging, or scattering.

Homicide-suicide in Victoria, Australia.

PubMed

Milroy, C M; Dratsas, M; Ranson, D L

1997-12-01

Thirty-nine incidents of homicide-suicide occurring in Victoria, Australia between 1985 and 1989 were examined. In 33 cases the assailants were men. The victims were spouses or women living in a de facto marriage. The majority of the victims were shot, and this was also the most frequent method of suicide. Breakdown in a relationship was the most frequent reason for killing. Mental illness of the assailant accounted for the killing in approximately 20% of cases. Physical ill health and financial stress were identified as important associative factors, particularly in the elderly. The pattern of homicide-suicide in Victoria is similar to that observed in other jurisdictions and represents an important and distinct subgroup of homicide.

An Evaluation of the Impacts of Changing Firearms Legislation on Australian Female Firearm Homicide Victimization Rates.

Reducing lethal violence against women requires comprehensive measures addressing individual, social, economic, cultural, and situational factors. Regarding situational factors, access to weapons-and firearm access in particular-has received notable research attention. However, most study comes from the United States of America, and findings may not apply elsewhere. The current study examines whether changing gun laws in Australia affected female firearm homicide victimization. Female firearm homicide victimization may have been affected; however, no significant impacts were found for male firearm homicide victimization. Findings suggest there may be value in preventing legal access to firearms by persons who have a history of intimate partner violence, although considerable further study is required.

Homicide and Klinefelter syndrome: a complex interaction.

Several studies have shown an association between homicide and sexual chromosomal abnormalities, but data are still lacking regarding Klinefelter syndrome. We retrospectively reviewed two cases of homicide perpetrators who were both diagnosed with Klinefelter syndrome on the basis of a karyotype analysis. A neurocognitive assessment was also performed (MMSE, Frontal Assessment Battery, brain CT, and electroencephalogram). Numerous intermediate risk factors of homicide were shared by our two cases, including dispositional (male gender, young age, low socioeconomic status), historical (prior arrest record and past conviction for any offense), contextual (unemployment), and clinical (alcohol abuse). It is important that clinicians go beyond obvious risk factors, such as chromosomal abnormalities, to pinpoint other meaningful risk factors and potentially facilitate preventive approaches.

Comparing Homicide-Suicides in the United States and Sweden.

Research on homicides followed by suicides has largely relied on very localized samples and relatively short time spans of data. As a result, little is known about the extent to which patterns within cases of homicide-suicides are geographically specific. The current study seeks to help fill this gap by comparing twenty years of homicide-suicide data for Sweden and a large U.S. county. Although some of the underlying patterns in the two countries are similar (e.g., decreasing rates), a number of important differences emerge, particularly with respect to incidence, weapons used, perpetrator age, and relationship of the perpetrator to the victim. © 2016 American Academy of Forensic Sciences.

2004-07-01

Female homicide is one of the leading causes of injury deaths in women. In most of such killings, spouses are usually involved because of one or the other reason. The purpose of the study is to identify the risk factors and nature of violence from victimologic point of view in female homicide. Information was obtained by interviewing the accompanying persons, postmortem examination and perusal of hospital records. There were 39 female victims of total 162 homicide. The peak age of the female homicide victim was 3rd decade. The victims were most frequently killed by their spouses. Argument (33.3%) and dowry (30.7%) were the most frequent reasons behind the crime. Majority of victims (84.6%) were killed in their home. Fatal wound is most frequently seen in head and defense wound is present only in nine cases. Considering sociological aspect of victim, 82% of the victims were from Hindu religion, majorities of them were married, illiterate, and drawn from low-socioeconomic status and rural community.

The acute effect of local homicides on children's cognitive performance

PubMed Central

Sharkey, Patrick

2010-01-01

This study estimates the acute effect of exposure to a local homicide on the cognitive performance of children across a community. Data are from a sample of children age 5–17 y in the Project on Human Development in Chicago Neighborhoods. The effect of local homicides on vocabulary and reading assessments is identified by exploiting exogenous variation in the relative timing of homicides and interview assessments among children in the same neighborhood but assessed at different times. Among African-Americans, the strongest results show that exposure to a homicide in the block group that occurs less than a week before the assessment reduces performance on vocabulary and reading assessments by between ∼0.5 and ∼0.66 SD, respectively. Main results are replicated using a second independent dataset from Chicago. Findings suggest the need for broader recognition of the impact that extreme acts of violence have on children across a neighborhood, regardless of whether the violence is witnessed directly.

2014-09-01

Homicide-suicide is a tragic phenomenon which typically does not result in a criminal charge or trial. However, correct diagnosis and classification of homicide-suicide cases are important to determine the perpetrators and dynamics of each category properly. The deaths in the homicide-suicide acts can be divided into two categories with respect to the number of involved individuals: dyadic deaths and triple or multiple deaths. These two categories can also be divided into two subgroups according to the chronology of the incidents: simultaneous deaths and consecutive deaths. Herein, a simultaneous homicide-suicide case of a father and daughter where both deaths occurred through drowning which was not found in the selected literature review and where the victim was a child is presented. The article aims to clarify the term discrepancies about multiple death cases in the literature and to discuss the pathological and psychosocial characteristics of the simultaneous dyadic death cases. © 2014 American Academy of Forensic Sciences.

The dead end of domestic violence: spotlight on children's narratives during forensic investigations following domestic homicide.

PubMed

Katz, Carmit

2014-12-01

The current study provides an in-depth exploration of the narratives of children who witnessed their father killing their mother. This exploration was conducted using a thematic analysis of the children's forensic interviews based on seven investigative interviews that were conducted with children following the domestic homicide. Investigative interviews were selected for study only for substantiated cases and only if the children disclosed the domestic homicide. All of the investigative interviews were conducted within 24h of the domestic homicide. Thematic analysis revealed the following four key categories: the domestic homicide as the dead end of domestic violence, what I did when daddy killed mommy, that one time that daddy killed mommy, and mommy will feel better and will go back home. The discussion examines the multiple layers of this phenomenon as revealed in the children's narratives and its consequences for professionals within the legal and clinical contexts.

Murder followed by suicide: filicide-suicide mothers in Italy from 1992 to 2010.

D'Argenio, Alberto; Catania, Giorgia; Marchetti, Marco

2013-03-01

The international literature shows that in 40-50% of the cases, homicides-suicides involving children under the age of 10 are committed by mothers. Here, we report some results on homicides-suicides, in the mother-child relationship, occurred in Italy between 1992 and 2010. We examined 36 cases of filicide-suicide mothers by consulting the archives of RAI, daily newspapers, and the ANSA news agency. We focused on: mothers and children's age, place of residence, date and place of the murder, number and sex of the murdered children, and modality of the homicide-suicide. At the time of the homicide-suicide, the average age of mothers was 35.4. The number of children killed by each mother was one, except in seven cases. All the women had underestimated psychopathological disorders and only six women were regularly treated. The dynamics and characteristics of the events were much more similar to suicides than homicides, so we can consider them as "extensive suicides." © 2013 American Academy of Forensic Sciences.

2011-02-01

This study aimed to describe the social, behavioural and offence characteristics of all convicted perpetrators of homicide aged 17 and under; to examine their previous contact with mental health services, and to discuss strategies for homicide prevention. An eight-year (1996-2004) sample of 363 juvenile homicide perpetrators in England and Wales was examined. The majority of perpetrators were male, used a sharp instrument, and most victims were acquaintances or strangers. Over half had previously offended. A history of alcohol and/or drug misuse was common, as was the prevalence of family dysfunction, abuse, educational difficulties or discipline problems. Previous contact with mental health services was rare. Earlier intervention targeting social and psychological adversity and substance misuse could help to reduce the level of risk for future violence, and may reduce homicide rates among juveniles. Strengthening engagement with young offenders and increasing resources to prevent recidivism may also be beneficial. Copyright © 2010 The Association for Professionals in Services for Adolescents.

Psychotherapy of Bereavement After Homicide

PubMed Central

RYNEARSON, TED

1994-01-01

The author presents guidelines for the assessment and initial treatment of bereavement after a homicide. Early interventions include nonverbal techniques applied in individual and group therapy. Because patients are over-whelmed and reactive, initial treatment strategy is supportive and focuses on reestablishing resiliency rather than on preexisting vulnerabilities (ambivalence, guilt, repression, denial). Adjustment to homicidal dying is lifelong, and therapist and patient should acknowledge that change may be limited. PMID:22700202

SOCIOECONOMIC CHANGE AND HOMICIDE IN A TRANSITIONAL SOCIETY

PubMed Central

Pridemore, William Alex; Kim, Sang-Weon

2008-01-01

Durkheim argued that rapid social change would produce anomic conditions which, in turn, would lead to increases in criminal and deviant behavior. Russia provides a unique opportunity to test this theory given the large-scale fundamental socioeconomic changes occurring in the nation. Russian homicide rates more than doubled in the years following the dissolution of the Soviet Union and are now among the highest in the world. The pace and effects of the socioeconomic transition vary widely throughout Russia, however, as do rates of and changes in violent crime. In this study, we took advantage of the unique natural experiment of the collapse of the Soviet Union to examine the association between socioeconomic change and homicide. We measured the negative effects of socioeconomic change by creating an index of changes in population size, unemployment, privatization, and foreign investment. Using data from Russian regions (n = 78) and controlling for other structural covariates, regression results indicated that regions that more strongly experienced the negative effects of socioeconomic change were regions where homicide rates increased the most between 1991 and 2000. Further analysis of the individual components of this index revealed that regions with greater increases in (1) unemployment experienced greater increases in homicide rates and (2) privatization experienced smaller increases in homicide rates.

Rethinking homicide: violence, race, and the politics of gender.

PubMed

Stark, E

1990-01-01

Although homicide is the fourth leading cause of premature mortality in the United States and the leading cause of death for young blacks, the health professions have been largely oblivious to violence. Prevailing explanations contribute to this neglect by emphasizing biological or psychiatric factors that make homicide unpredictable and cultural and environmental factors such as the emergence of a new "underclass" that link violence to race. Focusing on instances where no other crime is involved, this article proposes that "primary" homicide be reconceptualized as a by-product of interpersonal violence, a broad category of social entrapment rooted in the politics of gender inequality and including wife abuse, child abuse, and assaults by friends and acquaintances. The data show that blacks are no more violent than whites, though they are arrested and die more often as the consequence of violence. In addition, a majority of homicides are between social partners or involve gender stereotypes, are preceded by a series of assaults that are known to service providers, and grow out of "intense social engagement" about issues of male control and independence. Professional failure to respond appropriately is a major reason why assaults become fatal, particularly among blacks. An international strategy that combines sanctions against interpersonal assault, gun control, and the empowerment of survivors might prevent half of all homicides.

Medical homicide and extreme negligence.

PubMed

Duncanson, Emily; Richards, Virginia; Luce, Kasey M; Gill, James R

2009-03-01

Deaths that occur during medical care for the treatment of a disease are rarely certified as homicides. Some "medical" deaths, however, have been criminally prosecuted for manslaughter, reckless endangerment, or reckless homicide. We describe 5 deaths due to medical complications that underwent criminal prosecution. Three of the deaths were certified as homicides. Deaths certified as homicides due to the actions (or inactions) of a caregiver occur in 3 circumstances. The first is when the medical caregiver intentionally causes the death of the patient. The second is a death due to treatment by an unlicensed fraud or quack. The final circumstance is due to extreme medical negligence that involves a gross and wanton disregard for the well-being of the patient and is the most controversial in the medical community. The law defines reckless endangerment as the conscious disregard of a known substantial likelihood of injury to the patient. Criminal neglect typically is defined as the failure to provide timely, safe, adequate, and appropriate services, treatment, and/or care to a patient. In instances of extreme medical negligence, a homicide manner of death is appropriate because the fatality is due to the criminal acts (or inactions) of another. It also furthers one of the major goals of the medicolegal death investigation system, which is to safeguard the public health.

Recidivism Patterns Among Two Types of Juvenile Homicide Offenders: A 30-Year Follow-Up Study.

Khachatryan, Norair; Heide, Kathleen M; Hummel, Erich V

2018-02-01

Although juvenile homicide has been a matter of concern in the United States since the 1980s, prior research has not addressed long-term recidivism patterns for convicted juvenile murderers. Furthermore, a prominent juvenile homicide typology had not previously been tested with U.S. offenders. The present study examined whether juvenile offenders who killed or attempted to kill during the commission of a crime differed from those who killed due to some type of conflict on pre-incarceration, incarceration, and post-incarceration variables. These offenders were sentenced to adult prison in the early 1980s. Follow-up data spanned 30 years. The results indicated that approximately 88% of released offenders have been rearrested. Analyses of pre-incarceration variables revealed that crime-oriented offenders were significantly more likely to commit the homicide offense using accomplices than conflict-oriented offenders, and the latter were significantly more likely to use a firearm during the homicide incident. The circumstances of the homicide, however, were not significantly related to any other pre-incarceration variables, release from prison, number of post-release arrests, and number of post-release violent offenses. The implications of the findings, their comparability to previous follow-up research on this typology, and avenues for future research are discussed.

Emergency Department Visits Prior to Suicide and Homicide: Linking Statewide Surveillance Systems.

Emergency departments (EDs) serve a wide range of patients who present at risk of impending suicide and homicide. Two statewide surveillance systems were probabilistically linked to understand who utilizes EDs and then dies violently within 6 weeks. Each identified case was matched with four randomly selected controls on sex, race, date of birth, resident zip code, and date of ED visit vs. date of death. Matched-pair odds ratios were estimated by conditional logistic regression to assess differences between cases and controls on reported diagnoses and expected payment sources. Of 1,599 suicides and 569 homicides in the 3-year study period, 10.7% of decedents who died by suicide (mean = 13.6 days) and 8.3% who died by homicide (mean = 16.3 days) were seen in a state ED within 6 weeks prior to death. ED attendees who died by suicide were more likely to have a diagnosis of injury/ poisoning diagnosis or mental disorder and more likely to have Medicare. Those who died by homicide were more likely to have a diagnosis of injury/poisoning and less likely to have commercial insurance. It is essential for research to further explore risk factors for imminent suicide and homicide in ED patients who present for psychiatric conditions and general injuries.

Women victims of intentional homicide in Italy: New insights comparing Italian trends to German and U.S. trends, 2008-2014.

National statistics on female homicide could be a useful tool to evaluate the phenomenon and plan adequate strategies to prevent and reduce this crime. The aim of the study is to contribute to the analysis of intentional female homicides in Italy by comparing Italian trends to German and United States trends from 2008 to 2014. This is a population study based on data deriving primarily from national and European statistical institutes, from the U.S. Federal Bureau of Investigation's Uniform Crime Reporting and from the National Center for Health Statistics. Data were analyzed in relation to trends and age by Chi-square test, Student's t-test and linear regression. Results show that female homicides, unlike male homicides, remained stable in the three countries. Regression analysis showed a higher risk for female homicide in all age groups in the U.S. Middle-aged women result at higher risk, and the majority of murdered women are killed by people they know. These results confirm previous findings and suggest the need to focus also in Italy on preventive strategies to reduce those precipitating factors linked to violence and present in the course of a relationship or within the family.

Female versus male perpetrated femicide: an exploratory analysis of whether offender gender matters.

PubMed

Muftić, Lisa R; Baumann, Miranda L

2012-09-01

Femicide, the murder of females (most often at the hands of males), is an understudied area in homicide research. Furthermore, femicide perpetrated by females has been all but ignored. One reason this may be is because of the rarity of homicide victimization perpetrated by females. Rather, most homicide incidents consist of a male offender and a male victim. When a homicide does involve a female, either as a victim or as an offender, the other party implicated is generally a male. The primary goal of the proposed study is to provide an in-depth, albeit exploratory, examination of female-perpetrated femicide. Using homicide data taken from the Dallas Homicide Unit, 403 cases of femicide will be analyzed, with special attention devoted to comparing female-perpetrated femicide incidents (n = 39) against male-perpetrated femicide incidents (n = 364). Specifically, the current study will explore the similarities and differences in sociodemographic characteristics of victims and suspects, offense characteristics, and offense circumstances. Contrary to what was expected, results, at first glance, seem to suggest an overwhelming similarity between femicide suspects and victims, irrespective of gender. However, when the relationship between victim and suspect is considered, distinct differences appear. Implications from these findings as well as limitations and suggestions for further research are discussed.

Nineteen Victims of Homicide and Attempted Homicide in Sweden-Their Injuries, Cause of Death, and Offender Relationship.

Victims of homicide and attempted homicide are not uncommon in Sweden. We therefore aimed to study these victims to understand their injuries, their cause of death, and their relationship to the offender. All cases during five years in a district court in Sweden, where an offender had been convicted for homicide or attempted homicide, were identified and the court documents reviewed. Nineteen victims were identified; 14 males and five females, with an average age of 39.1 years. Although knife/sharp weapon was the most common weapon used, the use of firearm caused more deaths. Our study shows higher rates of firearm use than many other countries. The most common anatomical site to be injured by knife/sharp weapon and firearm was the thorax followed by the head. The most common cause of death was hypovolemia, followed by intracranial injuries. The high rate of firearm use shows that firearms are common modus operandi in Sweden often causing lethal injuries, if the offender intends to kill the victim. Our results support other studies showing that it is foremost injuries to the vessels, intracranial injuries, and injuries to intrathoracic organs, which causes a victim's death when assaulted with knife/sharp weapon or firearm.

2016-10-01

The forensic clinic for addiction treatment in Rostock is a forensic institution for patients who committed crimes under the influence of psychotropic substances. Regardless of the severity of the offence, patients receive different kinds of treatment depending on the therapy program. Criminal recidivism can be seen as one of the most important factors to validate success in treatment. Due to this purpose, an extensive recidivism study including all former patients from 2001 to 2012 was conducted at our clinic. The criminal court records as well as clinic-intern databases of 38 patients for whom homicide is the offence of referral and 38 patients with nonviolent crimes were analyzed for this study. The general recidivism rate for homicide delinquents was 47.7 %, but only 21 % of the examined patients were convicted to a new prison sentence. 7 homicide patients and 8 of the nonviolent group didn't finish the therapy successfully. Alcohol dependency was more common among the homicide patients. In addition, the average IQ was significantly lower than the comparison group. Compared to the nonviolent patients, homicide delinquents also got registered with a greater proportion of violent crimes during their criminal career. © Georg Thieme Verlag KG Stuttgart · New York.

The loss of a parent due to intimate partner homicide has a major impact on children. Professionals involved have to make far-reaching decisions regarding placement, guardianship, mental health care and contact with the perpetrating parent, without an evidence base to guide these decisions. We introduce a study protocol to a) systematically describe the demographics, circumstances, mental health and wellbeing of children bereaved by intimate partner homicide and b) build a predictive model of factors associated with children's mental health and wellbeing after intimate partner homicide. This study focuses on children bereaved by parental intimate partner homicide in the Netherlands over a period of 20 years (1993 - 2012). It involves an incidence study to identify all Dutch intimate partner homicide cases between 1993 and 2012 by which children have been bereaved; systematic case reviews to describe the demographics, circumstances and care trajectories of these children; and a mixed-methods study to assess mental health, wellbeing, and experiences regarding decisions made and care provided. Clinical experience and initial research suggest that the children involved often need long-term intensive mental health and case management. The costs of these services are extensive and the stakes are high. This study lays the foundation for an international dataset and evidence-informed decision making.

Homicide-suicide cases in Switzerland and their impact on the Swiss Weapon Law.

2010-12-01

Homicide followed by the suicide of the offender is a well-known phenomenon. In most cases, it takes place in the context of the so-called "family tragedies." A recent series of such family tragedies in Switzerland prompted an intensive debate in the media and the Swiss government concerning the Swiss Weapon Law, in particular the requirement to keep personal army weapons at home. The present study of Homicide-Suicide cases in Switzerland, thus focuses on the role played by guns, especially military weapons, in such crimes. We investigated retrospectively 75 cases of Homicide-Suicide, comprising 172 individuals and spanning a period of 23 years in western and central Switzerland. Our results show that if guns were used in 76% of the cases, army weapons were the cause of death in 25% of the total. In 28% of the deaths caused by a gunshot, the exact type of the gun and its origin could not be determined. Thus, the majority of Homicide-Suicide cases in Switzerland involve the use of guns. The exact percentage of cases were military weapons were involved could not be defined. In our opinion, a stricter weapons law, restricting access to firearms, would be a factor of prevention of Homicide- Suicide cases in Switzerland.

Homicides with direct and indirect links to the night-time economy.

PubMed

Tomsen, Stephen

2018-06-11

Alcohol use and homicide are a wide community concern with particular interest in understanding and preventing attacks (e.g. 'one punch' male on male attacks) in commercial nightlife settings with high levels of collective drinking. There is insufficient knowledge of the long-term patterns in this violence or the relationship between public drinking and flow on violence in other social settings. Alcohol-related homicides were those in which alcohol consumption was a contributing factor. Those also linked to purchase or consumption in locations where alcohol is sold after dark were classified as night-time economy related. The study comprised a first-hand analysis of files in the archive of the Australian National Homicide Monitoring Program in 2 years with a decade gap (1998/1999-2007/2008), and it classified 73 of all 238 alcohol-related incidents by direct or indirect relation to public nightlife settings. Related homicides in these years were not highly concentrated in developed night-time economies, but more spread outside major nightlife zones. Indirectly related killings were even more dispersed and included more women victims killed in domestic settings. There is a consistent though dispersed relationship between heavy public drinking at night and homicide. Concerns about homicide and night-time drinking leisure with mostly male victims attacked in well-known areas of busy city nightlife, must also consider the broader gendered patterns of 'flow on' nightlife-related incidents, including fatal semi-private and domestic violence that is indirectly but importantly related to drinking and alcohol purchase in public commercial nightlife. © 2018 Australasian Professional Society on Alcohol and other Drugs.

Homicidal deaths by firearms in Peshawar: an autopsy study.

2006-01-01

Medico legal autopsies can be valuable sources of information about the distribution of causes of reported deaths, particularly in homicidal cases. The present study provides information regarding the homicidal deaths due to firearm injuries in the district of Peshawar, NWFP, Pakistan. This descriptive study was conducted over the period of the year 2004. Data were collected from the autopsy records of the Department of Forensic Medicine, Khyber Medical College Peshawar and included all reported unnatural deaths from urban and rural areas of district Peshawar on whom autopsies were conducted in the department. Homicidal deaths constituted 77.7% (492/633) of all autopsies for the year 2004. Of 492 homicidal deaths, a vast majority of 452 (91.87%) were caused by firearm injuries. Among these, the male to female ratio was 5.5:1. The most common firearm weapon (418/452, 92.5%) were high velocity rifled weapons (Kalashnikov, rifles, pistols), followed by low velocity rifled weapons (18/452, 3.98%) and shotguns (16/452, 3.54%). A total of 956 injuries were found in various body areas, giving an average of over two injuries per person. The head, face and neck sustained the highest injuries (257, 26.9%), followed by the chest (248, 25.9%) and abdomen (149, 15.6%); the extremities, buttocks and genitalia together sustained 302 (31.6%) injuries. The vast majority of reported homicides in Peshawar are caused by firearm injuries, which bring up issues related to possession of firearms and changes in cultural attitudes towards use of firearms, if a decrease in firearm-related homicides is desired.

Aims and design This study employs unique newly available Russian mortality data to examine the social connection between binge drinking and homicide in the country. Setting, participants and measurements All death certificates of those aged 20–64 years in the Udmurt Republic, Russia, were analyzed according to day and cause of death for the years 1994–98. Deaths due to alcohol poisoning were used as a proxy for binge drinking. Findings There was a high bivariate correlation (r = 0.75) between the daily distribution of deaths due to alcohol and homicide. The number of alcohol deaths was significantly higher on Saturdays and Sundays (presumably as a result of drinking on Friday and Saturday nights) and the number of homicide deaths was significantly higher on Fridays and Saturdays. Conclusions The levels of alcohol consumption and homicide in Russia are among the highest in the world, and there is mounting evidence that the two are related. Binge drinking, preference for distilled spirits and a high social tolerance for heavy drinking may act as social and cultural contextual factors that might increase the risk of violent outcomes. The high correspondence between the daily distribution of alcohol and homicide deaths provides indirect evidence for the social connection between them. While these findings do not represent a causal connection, when placed in the context of the growing literature on this topic they provide further support of an association between alcohol consumption and homicide rates in Russia and preliminary evidence for the intermediate role in this relationship played by social context.

2015-02-01

Information on psychopathological characteristics of sexual homicide offenders is scarce. To investigate criminal, paraphilic and personality trait differences between serial and single-victim sexual homicide offenders. All 73 single-victim and 13 serial sexual homicide offenders presenting within a cohort of 671 men sentenced for sexual crimes between 1994 and 2005 and serving their sentence in one high-security Canadian prison and who consented to interview were assessed and compared on their offending patterns, personality pathology and paraphilic behaviours. Serial sexual homicide offenders were more likely than the single offenders to report deviant sexual fantasies, having selected victims with distinctive characteristics, to have targeted strangers, structured premeditation and/or verbal humiliation of their victims during the offences. Personality pathology, defined by at least two Diagnostic and Statistical Manual of Mental Disorders IV criteria for personality disorder, was common in both groups, but the serial offenders were more likely to have narcissistic, schizoid and/or obsessive-compulsive traits; they were also more likely to engage in sexual masochism, partialism, homosexual paedophilia, exhibitionism and/or voyeurism. Samples of serial sexual homicide offenders will, fortunately, always be small, and it may be that more could be learned to assist in preventing such crimes if data from several studies or centres were pooled. Our findings suggest that an investigation of sexual homicide offenders should include strategies for evaluating premeditation as well as personality and paraphilic characteristics. Crime scene features that should alert investigators should include similar characteristics between victims and particular aspects of body exposure or organisation.

Are pregnant and postpartum women: at increased risk for violent death? Suicide and homicide findings from North Carolina.

PubMed

2011-07-01

The purpose of this study is to estimate rates of suicide and homicide death among pregnant, postpartum and non-pregnant/non-postpartum women ages 14-44, and to determine comparative rates of violent death for pregnant and/or postpartum women compared to non-pregnant/non-postpartum women. North Carolina surveillance and vital statistics data from 2004 to 2006 were used to examine whether pregnant or postpartum women have higher (or lower) rates of suicide and homicide compared to other reproductive-aged women. The suicide rate for pregnant women was 27% of the rate for non-pregnant/non-postpartum women (rate ratio= 0.27, 95% CI = 0.11-0.66), and the suicide rate for postpartum women was 54% of the rate for non-pregnant/non-postpartum women (rate ratio = 0.54, 95% CI = 0.31-0.95). Homicide rates also were lower for pregnant and postpartum women, with the homicide rate for pregnant women being 73% of the rate for non-pregnant/non-postpartum women (rate ratio = 0.73, 95% CI = 0.39-1.37), and the homicide rate for postpartum women being half the rate for non-pregnant/non-postpartum women (rate ratio = 0.50, 95% CI = 0.26-0.98). Although pregnant and postpartum women are at risk for homicide and suicide death, the highest risk group is non-pregnant/non-postpartum women. Violence prevention efforts should target all women of reproductive age, and pay particular attention to non-pregnant/non-postpartum women, who may have less access to health care services than pregnant and postpartum women.

Late-life homicide-suicide: a national case series in New Zealand.

Homicide-suicide is a rare event, but it has a significant impact on the family and community of the perpetrator and victim(s). The phenomenon of late-life homicide-suicide has not been previously studied in New Zealand, and there is only limited data in the international literature. The aim of this study is to systematically review coroners' records of late-life homicide-suicides in New Zealand. After ethics approval was granted, the Coronial Services of New Zealand was approached to provide records of all closed cases with a suicide verdict (age 65+) over a five-year period (July 2007-December 2012). Of the 225 suicides, 4 cases of homicide-suicide were identified (an estimated incidence of 0.12 per 100,000 per persons year). All four perpetrators were men; three had been farmers. Their ages ranged from 65 to 82. One case occurred in the context of an underlying psychiatric illness (psychotic depression in bipolar disorder). Firearms were used in three cases. Two cases were categorized as spousal/consortial subtype, one case as filicide-suicide, and one case as siblicide-suicide. The prospect of major social upheaval in the form of losing their homes was present in all four cases. The findings of this case series were consistent with the limited existing literature on homicide-suicide. Age-related biopsychosocial issues were highlighted in this case series of late-life homicide-suicide. Additionally, evaluating firearm licences in high-risk groups may represent a prevention strategy. © 2015 The Authors. Psychogeriatrics © 2015 Japanese Psychogeriatric Society.

Cooperative Vehicular Networking: A Survey

PubMed Central

Ahmed, Ejaz

2018-01-01

With the remarkable progress of cooperative communication technology in recent years, its transformation to vehicular networking is gaining momentum. Such a transformation has brought a new research challenge in facing the realization of cooperative vehicular networking (CVN). This paper presents a comprehensive survey of recent advances in the field of CVN. We cover important aspects of CVN research, including physical, medium access control, and routing protocols, as well as link scheduling and security. We also classify these research efforts in a taxonomy of cooperative vehicular networks. A set of key requirements for realizing the vision of cooperative vehicular networks is then identified and discussed. We also discuss open research challenges in enabling CVN. Lastly, the paper concludes by highlighting key points of research and future directions in the domain of CVN. PMID:29881331

[Risk of homicide and major mental disorders: a critical review].

PubMed

Richard-Devantoy, S; Olie, J-P; Gourevitch, R

2009-12-01

Tragic and high profile killings by people with mental illness have been used to suggest that the community care model for mental health services has failed. It is also generally thought that schizophrenia predisposes subjects to homicidal behaviour. The aim of the present paper was to estimate the rate of mental disorder in people convicted of homicide and to examine the relationship between definitions. We investigated the links between homicide and major mental disorders. This paper reviews studies on the epidemiology of homicide committed by mentally disordered people, taken from recent international academic literature. The studies included were identified as part of a wider systematic review of the epidemiology of offending combined with mental disorder. The main databases searched were Medline. A comprehensive search was made for studies published since 1990. There is an association of homicide with mental disorder, most particularly with certain manifestations of schizophrenia, antisocial personality disorder and drug or alcohol abuse. However, it is not clear why some patients behave violently and others do not. Studies of people convicted of homicide have used different definitions of mental disorder. According to the definition of Hodgins, only 15% of murderers have a major mental disorder (schizophrenia, paranoia, melancholia). Mental disorder increases the risk of homicidal violence by two-fold in men and six-fold in women. Schizophrenia increases the risk of violence by six to 10-fold in men and eight to 10-fold in women. Schizophrenia without alcoholism increased the odds ratio more than seven-fold; schizophrenia with coexisting alcoholism more than 17-fold in men. We wish to emphasize that all patients with schizophrenia should not be considered to be violent, although there are minor subgroups of schizophrenic patients in whom the risk of violence may be remarkably high. According to studies, we estimated that this increase in risk could be associated with a paranoid form of schizophrenia and coexisting substance abuse. The prevalence of schizophrenia in the homicide offenders is around 6%. Despite this, the prevalence of personality disorder or of alcohol abuse/dependence is higher: 10% to 38% respectively. The disorders with the most substantially higher odds ratios were alcohol abuse/dependence and antisocial personality disorder. Antisocial personality disorder increases the risk over 10-fold in men and over 50-fold in women. Affective disorders, anxiety disorders, dysthymia and mental retardation do not elevate the risk. Hence, according to the DMS-IV, 30 to 70% of murderers have a mental disorder of grade I or a personality disorder of grade II. However, many studies have suffered from methodological weaknesses notably since obtaining comprehensive study groups of homicide offenders has been difficult. There is an association of homicide with mental disorder, particularly with certain manifestations of schizophrenia, antisocial personality disorder and drug or alcohol abuse. Most perpetrators with a history of mental disorder were not acutely ill or under mental healthcare at the time of the offence. Homicidal behaviour in a country with a relatively low crime rate appears to be statistically associated with some specific mental disorders, classified according to the DSM-IV-TR classifications.

The prevalence of homicide perpetrators with a diagnosis of schizophrenia is 6% in Western countries populations. The relationship between schizophrenia and homicide is complex and cannot be reduced to a simple causal link. The aim of this systematic review was to clarify the role of substance abuse in the commission of murder in people suffering from schizophrenia. A systematic English-French Medline and EMBASE literature search of cohort studies, case-control studies and transversal studies published between January 2001 and December 2011 was performed, combining the MeSH terms "schizophrenia", "psychotic disorders", "homicide", "violence", "substance use disorder", and the TIAB term "alcohol". Abstract selection was based on the STROBE and PRISMA checklist for observational studies and systematic and meta-analysis studies, respectively. Of the 471 selected studies, eight prospective studies and six systematic reviews and meta-analysis studies met the selection criteria and were included in the final analysis. Homicide committed by a schizophrenic person is associated with socio-demographic (young age, male gender, low socioeconomic status), historical (history of violence against others), contextual (a stressful event in the year prior to the homicide), and clinical risk factors (severe psychotic symptoms, long duration of untreated psychosis, poor adherence to medication). In comparison to the general population, the risk of homicide is increased 8-fold in schizophrenics with a substance abuse disorder (mainly alcohol abuse) and 2-fold in schizophrenics without any comorbidities. A co-diagnosis of substance abuse allows us to divide the violent schizophrenics into "early-starters" and "late-starters" according to the age of onset of their antisocial and violent behavior. The violence of the "early-starters" is unplanned, usually affects an acquaintance and is not necessarily associated with the schizophrenic symptoms. Substance abuse is frequent and plays an important role in the homicide commission. In addition, the risk of reoffending is high. In the "late-starters", the violence is linked to the psychotic symptoms and is directed to a member of the family. The reoffence risk is low and it depends on the pursuit of care or not. Defining subgroups of violent schizophrenic patients would avoid stigmatization and would help to prevent the risk of homicide by offering a multidisciplinary care which would take into account any substance abuse.

Gramaglia, Marco; Bernardos, Carlos J.; Calderon, Maria

2013-01-01

Induction loop detectors have become the most utilized sensors in traffic management systems. The gathered traffic data is used to improve traffic efficiency (i.e., warning users about congested areas or planning new infrastructures). Despite their usefulness, their deployment and maintenance costs are expensive. Vehicular networks are an emerging technology that can support novel strategies for ubiquitous and more cost-effective traffic data gathering. In this article, we propose and evaluate VIL (Virtual Induction Loop), a simple and lightweight traffic monitoring system based on cooperative vehicular communications. The proposed solution has been experimentally evaluated through simulation using real vehicular traces. PMID:23348033

Influence of ballistic and autopsy parameters on the manner of death in case of long firearms fatalities.

2008-05-20

A retrospective study was carried out on 132 fatalities due to gunshot wounds secondary to long firearms. One group of suicide (n=72) and one group of homicide (n=60) were statistically compared regarding age and sex of the victim, number of shots, range of fire, direction of the projectile(s), anatomical distribution of entrance sites, weapon and ammunition types and the nature of eventual associated traumatic lesions. The frequency of suicide was higher when the victim's age increased. Females constituted about 43% of the homicide victims and about 8% of the suicide victims. 51.5% of the homicide victims and about 10% of the suicide victims had sustained more than one gunshot wound. Close range was respectively found in 53.5% of the homicide cases and in all suicide cases. Most of the suicide cases (85% of the cases) showed typical entrance sites. Entrance sites in the limbs and lateral or posterior wall of the chest were only encountered in homicide cases. Associated traumatic lesions were found in about 23% of the homicide cases and in 18% of the suicide cases. In case of suicidal gunshots to the left chest, both upwards and downwards directions, and also both right-to-left and left-to-right directions can occur. From 22 suicide cases showing entrance wound in the mouth, a downwards direction was found in only one. This study underlines the importance but also the limits of the autopsy findings (including direction of the projectile(s) related to the entrance site) for giving an indication of the manner of death (homicide vs. suicide).

Suicide preceded by murder: the epidemiology of homicide-suicide in England and Wales 1988-92.

Barraclough, Brian; Harris, E Clare

We describe for the first time the epidemiology of homicide-suicide incidents for England and Wales. Previous descriptions have been of incidents in London (1946-62) and Yorkshire and Humberside (1975-1992). Death certificates were obtained for all who died in homicide-suicide incidents in England and Wales (1988-1992) that were reported by the police to the Home Office. Incidents were included in the analysis if the interval between death or fatal injury of victim and suspect was 3 or fewer days. Three hundred and twenty-seven people died in 144 incidents (180 victims and 147 suspects). Eighty per cent of incidents had one victim and one suspect. Three incidents were also suicide pacts between two suspects killing their children. Eighty-eight per cent of incidents exclusively involved members of the same family, 9 % acquaintances or strangers, and 3 % both family and acquaintances or strangers. Seventy-five per cent of victims were female, 85% of suspects male. The victims of male suspects were predominantly their womenfolk, past and present, and their children, and of female suspects their young children. Car exhaust and firearms accounted for 40% of victim and 50% of suspect deaths. Of all homicides during 1988-1992, 3 % of male, 11% of female and 19% of child deaths occurred in homicide-suicide incidents. Similarly, of all suicides, 0.8% of male and 0.4% of female deaths occurred in homicide-suicide incidents. Homicide-suicide in England and Wales is mostly 'a family matter', men of predominantly lower social class killing their kin, and pre-menopausal mothers their young children, before they kill themselves. A few men kill strangers during a crime and then themselves.

[Death by homicide in Colombia and Mexico: magnitude and trends, 2000-2011].

2014-07-01

To quantify the magnitude and explain the trends and impact of death by homicide in Colombia and Mexico between 2000 and 2011 at the national level and by sex. Data were obtained from national homicide statistics (Departamento Administrativo Nacional de Estadística [DANE], Colombia; and Instituto Nacional de Estadística y Geografía [INEGI], Mexico). Standardized death rates and years of life lost (YLL) were calculated (the latter assuming zero mortality) in people 15–49 years old. In Colombia, between 2000 and 2002, deaths by homicide increased from 71.3 to 76.7 per 100 000 (7.5%); by 2011 this figure had fallen to 36.1. YLL in the same period increased to 0.58 years overall, reducing temporary life expectancy by one year in men and 0.1 years in women. Between 2002 and 2011, YLL was 0.45 years in both sexes: 0.83 in men and 0.07 in women. This decline occurred mainly in persons over 45 years of age. In Mexico, between 2000 and 2007, homicide rates fell from 10.8 to 8.2 per 100,000 and YLL dropped by 24%. Between 2008 and 2011, mortality and YLL increased significantly in both sexes (191.2% and 164.5%, respectively), reducing life expectancy by 0.39 years in men and 0.04 years in women. It was corroborated that there has been a decline in deaths by homicide in Colombia and a significant rise in Mexico after a period of continuous reduction. Numerous actions should be taken to continue reducing homicides in Colombia and to reverse the current trend in Mexico.

Incidence of female homicide in the Transkei sub-region of South Africa (1993-2015).

Female homicide is very complex and difficult to research. Xhosa women are poor, illiterate and live in a rural area where they are exposed to a number of risks to their lives. The previous apartheid regimen broke the fabric of the family value system in this region and this came on top of a traditional patriarchal view of women as little more than property. Women are most vulnerable in this traumatised society. To study the incidence of female homicide in the Transkei sub-region of South Africa. A record review was undertaken of all medico-legal autopsies performed from 1993 to 2015 at Mthatha Forensic Pathology Laboratory. In total, 26 972 autopsies were performed on victims of unnatural death between 1993 and 2015. Of these, 6091 (22.58%) were cases of unnatural death among females. Homicide accounted for 1865 (30.61%) of these deaths. The average rate of female homicide during the study period was 12.5 per 100 000. The rate of homicide decreased from 14.25/100 000 (1993) to 9.19/100 000 (2015). The average rate of death was 4.93/100 000 as a result of the use of firearms, 3.75/100 000 for stab injuries and 3.70/100 000 for blunt trauma. The rate of murder was highest (6.55/100 000) in the young age group between 11 and 40 years. Despite a one and half time decrease in the rate of female homicide in the last 23 years (1993-2015) in the Transkei sub-region of South Africa, it is still three times higher than the worldwide rate.

Homicide mortality rates in Canada, 2000-2009: Youth at increased risk.

PubMed

Basham, C Andrew; Snider, Carolyn

2016-10-20

To estimate and compare Canadian homicide mortality rates (HMRs) and trends in HMRs across age groups, with a focus on trends for youth. Data for the period of 2000 to 2009 were collected from Statistics Canada's CANSIM (Canadian Statistical Information Management) Table 102-0540 with the following ICD-10-CA coded external causes of death: X85 to Y09 (assault) and Y87.1 (sequelae of assault). Annual population counts from 2000 to 2009 were obtained from Statistics Canada's CANSIM Table 051-0001. Both death and population counts were organized into five-year age groups. A random effects negative binomial regression analysis was conducted to estimate age group-specific rates, rate ratios, and trends in homicide mortality. There were 9,878 homicide deaths in Canada during the study period. The increase in the overall homicide mortality rate (HMR) of 0.3% per year was not statistically significant (95% CI: -1.1% to +1.8%). Canadians aged 15-19 years and 20-24 years had the highest HMRs during the study period, and experienced statistically significant annual increases in their HMRs of 3% and 4% respectively (p < 0.05). A general, though not statistically significant, decrease in the HMR was observed for all age groups 50+ years. A fixed effects negative binomial regression model showed that the HMR for males was higher than for females over the study period [RRfemale/male = 0.473 (95% CI: 0.361, 0.621)], but no significant difference in sex-specific trends in the HMR was found. An increasing risk of homicide mortality was identified among Canadian youth, ages 15-24, over the 10-year study period. Research that seeks to understand the reasons for the increased homicide risk facing Canada's youth, and public policy responses to reduce this risk, are warranted.

POVERTY, INFANT MORTALITY, AND HOMICIDE RATES IN CROSS-NATIONAL PERPSECTIVE: ASSESSMENTS OF CRITERION AND CONSTRUCT VALIDITY*

PubMed Central

Messner, Steven F.; Raffalovich, Lawrence E.; Sutton, Gretchen M.

2011-01-01

This paper assesses the extent to which the infant mortality rate might be treated as a “proxy” for poverty in research on cross-national variation in homicide rates. We have assembled a pooled, cross-sectional time-series dataset for 16 advanced nations over the 1993–2000 period that includes standard measures of infant mortality and homicide and also contains information on two commonly used “income-based” poverty measures: a measure intended to reflect “absolute” deprivation and a measure intended to reflect “relative” deprivation. With these data, we are able to assess the criterion validity of the infant mortality rate with reference to the two income-based poverty measures. We are also able to estimate the effects of the various indicators of disadvantage on homicide rates in regression models, thereby assessing construct validity. The results reveal that the infant mortality rate is more strongly correlated with “relative poverty” than with “absolute poverty,” although much unexplained variance remains. In the regression models, the measure of infant mortality and the relative poverty measure yield significant positive effects on homicide rates, while the absolute poverty measure does not exhibit any significant effects. Our analyses suggest that it would be premature to dismiss relative deprivation in cross-national research on homicide, and that disadvantage is best conceptualized and measured as a multidimensional construct.

Prolonged grief and post-traumatic stress among relatives of missing persons and homicidally bereaved individuals: A comparative study.

Traumatic loss (e.g., homicide) is associated with elevated prolonged grief disorder (PGD) and posttraumatic stress disorder (PTSD). Several studies comparing relatives of missing persons with homicidally bereaved individuals showed inconsistent results about the difference in PGD- and PTSD-levels between the groups. These studies were conducted in the context of armed conflict, which may confound the results. The current study aims to compare PGD- and PTSD-levels between the groups outside the context of armed conflict. Relatives of long-term missing persons (n=134) and homicidally bereaved individuals (n=331) completed self-report measures of PGD and PTSD. Multilevel regression modelling was used to compare symptom scores between the groups. Homicidally bereaved individuals reported significantly higher levels of PGD (d=0.86) and PTSD (d=0.28) than relatives of missing persons, when taking relevant covariates (i.e., gender, time since loss, and kinship to the disappeared/deceased person) into account. A limitation of this study is the use of self-report measures instead of clinical interviews. Prior studies among relatives of missing persons and homicidally bereaved individuals in the context of armed conflict may not be generalizable to similar samples outside these contexts. Future research is needed to further explore differences in bereavement-related psychopathology between different groups and correlates and treatment of this psychopathology.

Homicides of law enforcement officers responding to domestic disturbance calls.

Kercher, Cassandra; Swedler, David I; Pollack, Keshia M; Webster, Daniel W

2013-10-01

To describe the law enforcement officer (LEO), encounter, perpetrator and victim characteristics of domestic disturbance-related LEO homicides in the USA from 1996 to 2010. Narrative text analysis was conducted on the Federal Bureau of Investigation's annual report 'Law Enforcement Officers Killed and Assaulted'. Potential cases were confirmed if the narrative included the term 'domestic disturbance' or a domestic disturbance situation was described. 116 LEOs were killed while responding to domestic disturbance calls. Ninety-five per cent of these homicides were committed with a firearm. Sixty-seven per cent of LEOs were wearing body armour when killed; however, 52% received the fatal wound to the head/neck. Sixty-one per cent of suspects had a criminal history mentioned within the narratives and perpetrators of intimate partner violence (IPV) were more likely to be killed by LEOs than suspects involved in other forms of domestic violence. Victims of the domestic disturbance were killed in 21% of the IPV-related LEO homicide cases as opposed to only 5% of other domestic disturbance calls. A firearm was the most common weapon used in the murder of a domestic disturbance victim (86%). This study describes domestic disturbance-related LEO homicides. Future research in this area should further examine the dangers unique to domestic disturbance calls. A longitudinal analysis could provide greater understanding of the injury and mortality risks faced by LEOs, in order to inform homicide prevention among law enforcement.

Effect of 11 September 2001 on suicide and homicide in England and Wales.

2003-09-01

The tragic events of 11 September 2001 and televised scenes of the terrorists' homicidal and suicidal acts could have had an impact on the behaviour of some people, who harbour suicidal ideation or homicidal tendencies. To assess the effect of 11 September 2001 on the rate of suicide and homicide in England and Wales. Analysis of the number of suicides (ICD-9 codes: E950-E959), undetermined injury deaths (E980-E989) and homicides (E960-E969) in England and Wales in the 12 weeks before and after 11 September 2001 and during a similar period in the previous two years. The number of suicides reported in the month of September 2001 was significantly lower than other months in the same year and any September of the previous 22 years in England and Wales. A suicide reduction in men, regardless of age, occurred in the week starting Tuesday 11 September 2001. A reduction in female suicide occurred during the four weeks following the attack. There was no evidence of a similar effect on homicide. The tragic events of 11 September 2001 appear to have had a brief but significant inverse effect on suicide.The finding of this study supports Durkheim's theory that periods of external threat create group integration within society and lower the suicide rate through the impact on social cohesion.

The contribution of women to violent offending, including homicide, may be increasing as society changes. The aim of this paper was to test for trends in homicide by women in Finland. A retrospective register-based study was conducted by comparing two national cohorts: one from 1982 to 1992 and the other from 1993 to 2005. There was a small increase in the proportion of homicides committed by women over time, but the most striking difference between the cohorts was in the significantly higher frequency of alcohol abuse/dependence in the later cohort and of being under the influence of alcohol during the crime. Fewer perpetrators were regarded as lacking or being of diminished responsibility in the later cohort. The victims of the earlier cohort were emotionally closer to the offender than those of the later one. In Finland, there have been changes in characteristics of women who commit homicide and their crimes over time, with the apparent development of a subgroup of women who kill who are much more like men who kill than women in the 1980s and early 1990s. Preventing substance abuse and marginalization are likely to be important ways of preventing homicide by both female and male perpetrators. Copyright (c) 2008 John Wiley & Sons, Ltd.

"Gray murder": characteristics of elderly compared with nonelderly homicide victims in New York City.

2007-09-01

We compared characteristics of homicides among New York City residents aged 18 years and older from 1990 to 1998 to determine differences in demographics, cause and place of death, and presence of illicit drugs and alcohol in the deceased's system. All medical examiner-certified homicides among New York City residents aged 18 years and older from 1990 to 1998 were studied (n = 11,850). Nonelderly (aged 18 to 64 years) and elderly (aged 65 years and older) victims were compared by gender, race/ethnicity, cause of death, place of death, and presence of illicit drugs or alcohol. Population-based homicide rates stratified by age, gender, and race were also calculated. Nonelderly homicide victims were significantly more likely to be male, non-White, to have been shot in the city streets, and to have evidence of illicit drug or alcohol use. Elderly victims were more likely to be female, White, to have been killed by nonfirearm injuries, and to have been killed in their own homes. The gender and race differences between age groups remained but were attenuated when population-based rates were compared. The characteristics of homicide in nonelderly adults do not apply to elderly adults in New York City. Demographic factors and vulnerabilities of the elderly may underlie these differences, pointing to the need for oversight of isolated or homebound elderly persons and for protective interventions.

This study provides a retrospective review from the forensic files of the University Centre of Legal Medicine in Western Switzerland in Geneva, from January 1956 to December 2005. The studied homicide-suicide cases cover a period of half a century (50 years). As a rule, all police-ordered forensic examinations of violent death cases in the Canton of Geneva are conducted by the University Centre of Legal Medicine. All of the data necessary for an exhaustive retrospective study are thus readily available. During the period covered in this work, 228 homicides were perpetrated in Geneva. In 23 cases, the homicide was followed by the suicide of the aggressor. The 34 victims of these homicides (18 women, 1 man and 15 children) had either an intimate or filial relationship with the perpetrator. Most of the suicidal perpetrators were men that killed their spouses or intimate partners, with children as additional victims in some cases. Shooting was the most common means to kill, followed by stabbing. The majority of the victims and perpetrators were Swiss nationals. This retrospective study shows that in the last 50 years, homicide-suicide cases in the Canton of Geneva have been a rare and an episodic phenomena with a very variable frequency from 1 year to another.

[Understanding homicides in Latin America: poverty or institutionalization?].

Briceño-León, Roberto

2012-12-01

Homicides occur the world over, but they are not homogeneously distributed by geographical areas (continents, countries, regions), either over long or short periods of time, or in social groups, namely age, gender, social class or ethnicity. Why are there more homicides in some countries than in others? Why do killings increase in some countries, while they decrease in others? There are two fundamental schools of thought for social explanations of crime and violence: those attributing its origins to poverty and inequality and those blaming institutionalization or social norms. To discuss these theories, this paper analyzes and compares the changes in Colombia, Venezuela and Brazil in the first decade of the twenty-first century, where the homicide rate has decreased, increased and remained the same, respectively. Using the measurement of six variables (poverty, inequality, unemployment, national wealth, human development and the rule of law) and the technique of trajectory analysis, the results revealed that institutionalization is more to blame for the change than poverty and inequality. The text concludes that poverty and inequality affect crime and homicides, although not directly, but mediated by the institutions instead.

Perpetrators of homicide with schizophrenia: a national clinical survey in England and Wales.

Few studies have described rates of schizophrenia in a national sample of homicide perpetrators. This study aimed to describe this group's social and clinical characteristics, mental state features, offense details, and outcome in court. Analyses used a national clinical survey that collected data on people convicted of homicide in England and Wales (1996-1999). Data were collected for those with schizophrenia or other delusional disorders from psychiatric reports and questionnaires. Of the 1,594 people convicted of homicide, 85 (5 percent) had schizophrenia. Of the 57 people with schizophrenia for whom data were available, 32 (56 percent) had been ill for less than 12 months, and in the month before the offense, 32 (56 percent) had shown a change in the quality, intensity, or conviction of or emotional response to their delusional beliefs. Twenty-four (28 percent) had no previous contact with psychiatric services. Regular assessment of delusions may help to detect an increased risk of violence, including homicide. More intensive care should be available for patients with a history of schizophrenia and previous violence.

Previous studies of people convicted of homicide have used different definitions of mental disorder. To estimate the rate of mental disorder in people convicted of homicide; to examine the relationship between definitions, verdict and outcome in court. A national clinical survey of people convicted of homicide (n=1594) in England and Wales (1996-1999). Rates of mental disorder were estimated based on: lifetime diagnosis, mental illness at the time of the offence, contact with psychiatric services, diminished responsibility verdict and hospital disposal. Of the 1594,545 (34%) had a mental disorder: most had not attended psychiatric services; 85 (5%) had schizophrenia (lifetime); 164 (10%) had symptoms of mental illness at the time of the offence; 149 (9%) received a diminished responsibility verdict and 111 (7%) a hospital disposal - both were associated with severe mental illness and symptoms of psychosis. The findings suggest an association between schizophrenia and conviction for homicide. Most perpetrators with a history of mental disorder were not acutely ill or under mental healthcare at the time of the offence. Some perpetrators receive prison sentences despite having severe mental illness.

Israeli mothers' meaning reconstruction in the aftermath of homicide.

2016-01-01

This study is the first to our knowledge to provide an in-depth account of the meanings reconstructed by bereaved Israeli mothers of homicide victims. Homicide survivors tend to receive little or no support from society; this is especially true in Israel, where homicide victims are a neglected population whose voice is socially muted. Constructivist theories have informed understanding of grief, emphasizing the role of meaning reconstruction in adaptation to bereavement, as well as the role of social support in the process of meaning reconstruction. We derived 3 prototypes of meaning from interviews of 12 bereaved mothers: the existential paradox; a bifurcated worldview; and oppression, mortification, and humiliation. Most informants used all 3 prototypes in the process of reconstructing meaning, describing changes in the perception of themselves, the world, and society. However, change was also accompanied by continuity, because participants did not abandon their former worldview while adopting a new one. The findings suggest that meaning reconstruction in the aftermath of homicide is a unique, multifaceted, and contradictory process. Implications for practice are outlined.

Sexual Murderers: Sex Offender, Murderer, or Both?

PubMed

Beauregard, Eric; DeLisi, Matt; Hewitt, Ashley

2017-06-01

Sexual murderers perpetrate homicide and rape/sexual abuse, but it is unclear whether they should primarily be considered homicide offenders, sexual offenders, or both. Most studies have merged together different types of non-homicidal sex offenders (NHSOs), neglecting to consider the potential differences between the nonviolent and violent sex offenders. Here, we suggest it is important to isolate those violent sex offenders who inflict severe physical injuries that could potentially lead to a lethal outcome. Therefore, the aim of the current study is to compare different measures of the criminal career on three groups of sex offenders: NHSOs, violent NHSOs, and sexual homicide offenders (SHOs) using data from 616 incarcerated male sex offenders in a Federal penitentiary in Canada. Interestingly, the group of sex offenders with the worst criminal career profile was not the SHOs, but the violent NHSOs. Violent NHSOs had the greatest number of prior convictions and the most varied and versatile criminal career. Therefore, we suggest that based on their criminal career, SHOs should be considered more as murderers than sex offenders. However, to fully answer this question, future studies should include a group of non-sexual homicide offenders.

Adolescent female murderers: characteristics and treatment implications.

Roe-Sepowitz, Dominique

2007-07-01

This study examines individual and family characteristics of a population of 29 adolescent females charged with homicide or attempted homicide in the juvenile justice system. The purpose of this study is to contribute to the limited knowledge about adolescent females charged with homicide. Data were collected including the MAYSI-2, a risk classification instrument, and social, educational and family histories. Findings include high rates of reported substance use, delinquent peers, early indicators of mental health problems, and limited control and supervision by parents. The most common weapon used was a car and the most common victim was a known person. A comparison was conducted on girls charged with homicide during the commission of another crime or committed during a conflict. The conflict group was found to victimize friends and family significantly more often than the crime group. The crime group showed higher use of alcohol and drugs, used a gun more and had co-offenders at a higher rate. A profile was developed to describe the typical adolescent female homicide offender found in this study. Treatment recommendations and future research were discussed.

Williams, D J; Vincent, Jolene

2018-04-23

Recently, scholars in literary criminology and leisure sciences have begun to explore the role of broader leisure culture in potentially shaping fantasy development, planning, preparation, and execution in specific cases of expressive homicide. This brief report focuses on an unusual case of expressive homicide, wherein two teen offenders in Idaho collaborated to murder a female classmate as an intentional leisure activity. Prior to the murder, the offenders created a videotape describing how they planned to commit this (and additional) murders. A careful analysis of the videotape content, along with other primary court documents, illustrates how leisure preferences can combine with traditional psychiatric variables to shape the unique process of certain forms of expressive homicide. © 2018 American Academy of Forensic Sciences.

Homicide during postictal psychosis.

PubMed

Eisenschenk, Stephan; Krop, Harry; Devinsky, Orrin

2014-01-01

Postictal psychosis is characterized by a fluctuating combination of thought disorder, auditory and visual hallucinations, delusions, paranoia, affective change, and aggression including violent behavior. We present a case of homicide following a cluster of seizures. The patient's history and postictal behavior were his consistent with postictal psychosis. Contributing factors resulting in homicide may have included increased seizure frequency associated with a change in his AED regimen seizure frequency. The AED change to levetiracetam may also have increased impulsiveness with diminished mood regulation following discontinuation of carbamazepine. There is evidence that he had a cluster of seizures immediately prior to the murder which may have resulted in the postictal disinhibition of frontal lobe inhibitory systems. This homicide and other violent behaviors associated with postictal psychosis may be avoided with earlier recognition and treatment.

Determination of the manner of death in case of intraoral firearm wounds can be a challenge, especially if the circumstances of the incident are unclear and crime scene investigation is inadequate. It is a well-known fact that the mouth is one of the selected sites for suicide with firearms. Homicidal shooting through the mouth is said to be rare, but does occur, and can be mistaken for a suicide. For discrimination between suicide and homicide in cases of intraoral firearm wounds, some useful points are the site of entry wound, the direction of the internal bullet path, the range of fire and the circumstances of death. We demonstrate these points in a case of a homicidal gunshot to the mouth assessed by both classical autopsy and post-mortem CT (PMCT).

Low Emissions and Delay Optimization for an Isolated Signalized Intersection Based on Vehicular Trajectories

PubMed Central

2015-01-01

A traditional traffic signal control system is established based on vehicular delay, queue length, saturation and other indicators. However, due to the increasing severity of urban environmental pollution issues and the development of a resource-saving and environmentally friendly social philosophy, the development of low-carbon and energy-efficient urban transport is required. This paper first defines vehicular trajectories and the calculation of vehicular emissions based on VSP. Next, a regression analysis method is used to quantify the relationship between vehicular emissions and delay, and a traffic signal control model is established to reduce emissions and delay using the enumeration method combined with saturation constraints. Finally, one typical intersection of Changchun is selected to verify the model proposed in this paper; its performance efficiency is also compared using simulations in VISSIM. The results of this study show that the proposed model can significantly reduce vehicle delay and traffic emissions simultaneously. PMID:26720095

Reducing Homicide Risk in Indianapolis between 1997 and 2000

PubMed Central

McGarrell, Edmund F.

2010-01-01

Rates of homicide risk are not evenly distributed across the US population. Prior research indicates that young males in disadvantaged urban neighborhoods are particularly vulnerable to lethal violence. The traditional criminal justice response to violent crime in the urban context has the potential to exacerbate problems, particularly when broad-based arrest sweeps and general deterrence initiatives are the standard models used by law enforcement. Recent studies suggest that alternative intervention approaches that use both specific deterrence combined with improving pro-social opportunities has shown promise in reducing violent crime in these high-risk contexts. This paper examines the changes in homicide patterns for the highest-risk populations in Indianapolis after a “pulling levers” intervention was implemented in the late 1990s to address youth, gang, and gun violence. Multilevel growth curve regression models controlling for a linear trend over time, important structural correlates of homicide across urban neighborhoods, and between-neighborhood variance estimates showed that homicide rates involving the highest-risk populations (i.e., actors 15 to 24 years old) were most likely to experience a statistically significant and substantive reduction after the intervention was implemented (IRR = 0.48, 95% CI = 0.29 – 0.78). Among male actors in this age range, Black male homicide rates (IRR = 0.41, 95% CI = 0.25 – 0.70) and White male rates (IRR = 0.38, 95% CI = 0.15 – 0.79) declined substantially more than homicide rates involving actors outside the 15 to 24 years age range (IRR = 0.95, 95% CI = 0.54 – 1.69). In addition, neighborhoods where specific, community-level strategies were implemented had statistically significant and substantive high-risk homicide rate declines. We conclude that further extension of the pulling levers framework appears warranted in light of the recent findings. Alternative justice strategies that rely on the threat of sanctions coupled with strengthening social service provisions, as well as risk communication aimed at high-risk individuals, appears to hold significant promise as a means to reduce lethal violence.

2015-11-01

We present the dynamic model of the chain-reaction crash to take account of the vehicular size. Drivers brake according to taillights of the forward vehicle. We investigate the effect of the vehicular size on the chain-reaction crash (multiple-vehicle collision) in the traffic flow controlled by taillights. In the multiple-vehicle collision, the first crash induces more collisions. We investigate how the first collision induces the chain-reaction crash numerically. We derive, analytically, the transition points and the region maps for the chain-reaction crash in the traffic flow of vehicles with finite sizes. We clarify the effect of the vehicular size on the multiple-vehicle collision.

Vehicular pollution is one of the major contributors to the air pollution in urban areas and perhaps and accounts for the major share of anthropogenic green-house gases such as carbon dioxide, carbon monoxide, nitrogen oxides. Knowledge of human health risks related to environmental exposure to vehicular pollution is a current concern. Analyze the range health effects are attributed varied constituents of vehicular air pollution examine evidence for a causal association to specific health effect. In many instances scenario involves exposure to very low doses of putative agents for extended periods, sometimes the period could mean over a lifetime of an individual and yet may result in small increase in health risk that may be imperceptible. Secondary data analysis and literature review. In environmental exposures, traditional epidemiological approaches evaluating mortality and morbidity indicators display many limiting factors such as nonspecificity of biological effects latency time between exposure and magnitude of the effect. Long latency period between exposure and resultant disease, principally for carcinogenic effects and limitation of epidemiological studies for detecting small risk increments. The present paper discusses the methodological challenges in studying vehicular epidemiology and highlights issues that affect the validity of epidemiological studies in vehicular pollution.

Vehicular emissions are one of major anthropogenic sources of ambient volatile organic compounds (VOCs) in Hong Kong. During the past twelve years, the government of the Hong Kong Special Administrative Region has undertaken a series of air pollution control measures to reduce vehicular emissions in Hong Kong. Vehicular emissions were characterized by repeated measurement in the same roadway tunnel in 2003 and 2015. The total net concentration of measured VOCs decreased by 44.7% from 2003 to 2015. The fleet-average VOC emission factor decreased from 107.1 ± 44.8 mg veh-1 km-1 in 2003 to 58.8 ± 50.7 mg veh-1 km-1 in 2015, and the total ozone (O3) formation potential of measured VOCs decreased from 474.1 mg O3 veh-1 km-1 to 190.8 mg O3 veh-1 km-1. The emission factor of ethene, which is one of the key tracers for diesel vehicular emissions, decreased by 67.3% from 2003 to 2015 as a result of the strict control measures on diesel vehicular emissions. Total road transport VOC emissions is estimated to be reduced by 40% as compared with 2010 by 2020, which will be an important contributor to achieve the goal of total VOC emission reduction in the Pearl River Delta region. The large decrease of VOC emissions from on-road vehicles demonstrates the effectiveness of past multi-vehicular emission control strategy in Hong Kong.

Secure and Lightweight Cloud-Assisted Video Reporting Protocol over 5G-Enabled Vehicular Networks

PubMed Central

2017-01-01

In the vehicular networks, the real-time video reporting service is used to send the recorded videos in the vehicle to the cloud. However, when facilitating the real-time video reporting service in the vehicular networks, the usage of the fourth generation (4G) long term evolution (LTE) was proved to suffer from latency while the IEEE 802.11p standard does not offer sufficient scalability for a such congested environment. To overcome those drawbacks, the fifth-generation (5G)-enabled vehicular network is considered as a promising technology for empowering the real-time video reporting service. In this paper, we note that security and privacy related issues should also be carefully addressed to boost the early adoption of 5G-enabled vehicular networks. There exist a few research works for secure video reporting service in 5G-enabled vehicular networks. However, their usage is limited because of public key certificates and expensive pairing operations. Thus, we propose a secure and lightweight protocol for cloud-assisted video reporting service in 5G-enabled vehicular networks. Compared to the conventional public key certificates, the proposed protocol achieves entities’ authorization through anonymous credential. Also, by using lightweight security primitives instead of expensive bilinear pairing operations, the proposed protocol minimizes the computational overhead. From the evaluation results, we show that the proposed protocol takes the smaller computation and communication time for the cryptographic primitives than that of the well-known Eiza-Ni-Shi protocol.

The inpatient evaluation and treatment of a self-professed budding serial killer.

PubMed

Reisner, Andrew D; McGee, Mark; Noffsinger, Stephen G

2003-02-01

The authors present the case of a man who was hospitalized after claiming that he was about to become a serial killer. The patient presented with extensive written homicidal fantasies and homicidal intentions without evidence of actual homicidal acts. In addition to routine assessments, hospital staff members used case conferences, psychological testing, outside forensic consultation, and a forensic review process to make decisions regarding diagnosis, treatment planning, and discharge. The patient was discharged after 8 months of inpatient treatment and was apparently free of homicidal impulses or symptoms of severe mental illness. A 2-year court commitment allowed for the enactment and potential enforcement of a discharge plan that was endorsed by the patient, the hospital, and community care providers. The authors review diagnostic and risk management issues. Comparisons with known features of typical serial killers are made.

To understand the circumstances surrounding the occupational homicides of law enforcement officers (LEOs) in the USA. Narrative text analysis of Federal Bureau of Investigation Law Enforcement Officers Killed and Assaulted reports. A total of 796 officers were killed in the line of duty between 1996 and 2010. The occupational homicide rate during the time peaked in 2001 at 3.76/100 000 (excluding those killed during the September 11 2001 terrorist attacks), and was lowest in 2008 at 1.92/100 000. Most LEOs (67%) were killed by short-barrel firearms; 10% were killed with their own service weapon. The most frequent encounter with a suspect prior to a homicide was responding to a disturbance call. These results should inform officer training and the policies, as well as procedures used when interacting with suspects, especially when firearms are involved.

Homicide patterns vary from country to country, influenced by many factors. In the two-year period from January 1998 to December 1999, 82 homicide victims were autopsied. The sex ratio was about three males for one female. The largest number of victims was found in the age group 21-30 years. Assaults with blunt weapons were the most common means. Acquaintances committed 34% of homicides. In contrast to males, the killing of a female by a stranger was rare. Revenge was the most common reason followed by arguments. In 40.2% of cases, the location of crime was outdoors, 37.8% were at the victim's house and in 9.7% of cases, the crime was committed at another domicile such as the offender's house, lodgings or a relative's house. In 14.7% of cases, the dead bodies were located away from the scene of crime.

"Bessie done cut her old man": race, common-law marriage, and homicide in New Orleans, 1925-1945.

Adler, Jeffrey S

This essay examines domestic homicide in early twentieth-century New Orleans. African-American residents killed their domestic partners at eight times the rate of white New Orleanians, and these homicides were most often committed by women, who killed their partners at fifteen times the rate of white women. Common-law marriages proved to be especially violent among African-American residents. Based on nearly two hundred cases identified in police records and other sources as partner killings between 1925 and 1945, this analysis compares lethal violence in legal marriages and in common-law unions. It also explores the social and institutional forces that buffeted common-law marriages, making this the most violent domestic arrangement and contributing to the remarkably high rate of spousal homicide by African-American women in early twentieth-century New Orleans.

Business structure, ethnic shifts in labor markets, and violence: the link between company size, local labor markets, and non-Latino homicide.

Combining several schools of thought, including the civic engagement thesis, we extend current research by linking three things at the county level; firm size, the ethnic composition of labor markets, and violent crime. Our results suggest that larger businesses (based on the average number of persons employed) are more likely to have an external orientation and long recruitment reach, and this is linked to ethnic shifts in labor markets toward Latino workers. Such shifts are in turn associated with high rates of homicide among non-Latinos. Through indirect effects modeling, we find that increases in Black homicide are linked to rises in concentrated poverty, while increases in White homicide are linked to changes in unemployment. We discuss the implications of our findings. Copyright © 2014 Elsevier Inc. All rights reserved.

Women's police stations and intimate partner violence: Evidence from Brazil.

PubMed

Perova, Elizaveta; Reynolds, Sarah Anne

2017-02-01

Although women's police stations have gained popularity as a measure to address intimate partner violence (IPV), there is little quantitative evaluation of their impacts on the incidence of IPV. This paper estimates the effects of women's police stations in Brazil on female homicides, a measure of the most severe form of IPV. Given that a high fraction of female deaths among women ages 15-49 years can be attributed to aggression by an intimate partner, female homicides appear the best proxy for severe IPV considering the scarcity of data on IPV in Brazil. We assemble a panel of 2074 municipalities from 2004 to 2009 and apply a difference-in-differences approach using location and timing to estimate the effect of establishing a women's police station on the municipal female homicide rate. Although we do not find a strong association on average, women's police stations appear to be highly effective among young women living in metropolitan areas. Establishing a women's police station in a metropolitan municipality is associated with a reduction in the female homicide rate by 1.23 deaths per 100,000 women ages 15-49 years (approximately a 17 percent reduction in the female homicide rate in metropolitan municipalities). The reduction in the homicide rate of women ages 15 to 24 is even higher: 5.57 deaths per 100,000 women. Better economic opportunities and less traditional social norms in metropolitan areas may explain the heterogeneous impacts of women's police stations. Copyright © 2016. Published by Elsevier Ltd.

Is patriarchy the source of men's higher mortality?

PubMed Central

Stanistreet, D; Bambra, C; Scott-Samuel, A

2005-01-01

Objective: To examine the relation between levels of patriarchy and male health by comparing female homicide rates with male mortality within countries. Hypothesis: High levels of patriarchy in a society are associated with increased mortality among men. Design: Cross sectional ecological study design. Setting: 51 countries from four continents were represented in the data—America, Europe, Australasia, and Asia. No data were available for Africa. Results: A multivariate stepwise linear regression model was used. Main outcome measure was age standardised male mortality rates for 51 countries for the year 1995. Age standardised female homicide rates and GDP per capita ranking were the explanatory variables in the model. Results were also adjusted for the effects of general rates of homicide. Age standardised female homicide rates and ranking of GDP were strongly correlated with age standardised male mortality rates (Pearson's r = 0.699 and Spearman's 0.744 respectively) and both correlations achieved significance (p<0.005). Both factors were subsequently included in the stepwise regression model. Female homicide rates explained 48.8% of the variance in male mortality, and GDP a further 13.6% showing that the higher the rate of female homicide, and hence the greater the indicator of patriarchy, the higher is the rate of mortality among men. Conclusion: These data suggest that oppression and exploitation harm the oppressors as well as those they oppress, and that men's higher mortality is a preventable social condition, which could be tackled through global social policy measures.

2015-12-01

The deaths of American hip-hop and rap recording artists often receive considerable media attention. However, these artists' deaths have not been examined as a distinct group like the deaths of rock, classical, jazz, and pop music artists. This is a seminal epidemiological analysis on the deaths of an understudied group, American hip-hop and rap music recording artists. Media reports were analyzed of the deaths of American hip-hop and rap music recording artists that occurred from January 1, 1987 to December 31, 2014. The decedents' age, sex, race, cause of death, stage names, and city and state of death were recorded for analysis. The most commonly reported cause of death was homicide. The 280 deaths were categorized as homicide (55%), unintentional injury (13%), cardiovascular (7%), undetermined/undisclosed (7%), cancer (6%), other (5%), suicide (4%), and infectious disease (3%). The mean reported age at death was 30 yrs (range 15-75) and the median was 29 yrs; 97% were male and 92% were black. All but one of the homicides were committed with firearms. Homicide was the most commonly reported cause of death. Public health focus and guidance for hip-hop and rap recording artists should mirror that for African-American men and adolescent males ages 15-54 yrs, for whom the leading causes of death are homicide, unintentional injury, and heart disease. Given the preponderance of homicide deaths in this analysis, premature mortality reduction efforts should focus on violence prevention and conflict mitigation.

“Gray Murder”: Characteristics of Elderly Compared With Nonelderly Homicide Victims in New York City

Abrams, Robert C.; Leon, Andrew C.; Tardiff, Kenneth; Marzuk, Peter M.; Sutherland, Kari

2007-01-01

Objectives. We compared characteristics of homicides among New York City residents aged 18 years and older from 1990 to 1998 to determine differences in demographics, cause and place of death, and presence of illicit drugs and alcohol in the deceased’s system. Methods. All medical examiner–certified homicides among New York City residents aged 18 years and older from 1990 to 1998 were studied (n = 11 850). Nonelderly (aged 18 to 64 years) and elderly (aged 65 years and older) victims were compared by gender, race/ethnicity, cause of death, place of death, and presence of illicit drugs or alcohol. Population-based homicide rates stratified by age, gender, and race were also calculated. Results. Nonelderly homicide victims were significantly more likely to be male, non-White, to have been shot in the city streets, and to have evidence of illicit drug or alcohol use. Elderly victims were more likely to be female, White, to have been killed by nonfirearm injuries, and to have been killed in their own homes. The gender and race differences between age groups remained but were attenuated when population-based rates were compared. Conclusions. The characteristics of homicide in nonelderly adults do not apply to elderly adults in New York City. Demographic factors and vulnerabilities of the elderly may underlie these differences, pointing to the need for oversight of isolated or homebound elderly persons and for protective interventions.

Previous research on the toxicology of homicide has shown that about half of offenders and victims have psychoactive substances in their blood. The purpose of this study was to examine this topic in a Swedish setting. Toxicological data were sought in a database for all victims (n=273) and perpetrators (n=257) of homicide in Sweden from 2007 to 2009. Sufficient tests were identified for 97.1% of all victims (n=265) and 46.7% of all offenders (n=120). Additional information was obtained from court records and police reports. A majority of individuals involved in homicides displayed positive toxicology (57.0% of victims and 62.5% of offenders). The most commonly detected substances, in both victims and offenders, were ethanol (44.9% vs. 40.8%) and benzodiazepines (8.3% vs. 19.2%). The difference between offenders and victims concerning benzodiazepines was statistically significant (OR 2.6; p=0.002). Perpetrators of homicide–suicide had a lower prevalence of positive toxicology (30.8%) than other homicide offenders (67.3%; p = 0.01) [corrected] and victims in unsolved cases more often exhibited positive drug toxicology compared to victims in solved cases (36.1% vs. 8.3%; p < 0.001) corrected. The results of the study support the notion that substance abuse is firmly linked to committing homicide and to becoming a victim thereof. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Violent Behaviors, Weapon Carrying, and Firearm Homicide Trends in African American Adolescents, 2001-2015.

2018-04-07

African American youths have the highest risk for firearm and other weapon related homicides. This study utilized the national Youth Risk Behavior Surveys from 2001 to 2015 to assess trends in violence related behaviors and weapon carrying of African American adolescents. Our analyses found statistically significant reductions in physical fighting and weapon carrying among African American male adolescents from 2007 to 2015. Planning suicide increased in both male and female African American adolescents since 2007. In addition, the number of firearm homicides increased in African American males. African American females and males had groups of items highly predictive of weapon carrying behaviors: alcohol, tobacco, and other drug use and violent risk behaviors. Both female and male students who made mostly A's or B's in school were significantly less likely to carry weapons in and out of school. Our findings indicate that firearm homicides have increased in African American adolescents, but weapon carrying in school going adolescents has significantly declined. School engagement and satisfactory school performance seems to have a significant protective effect on firearm homicides and violent behavior risks in African American adolescents.

[Uncovering an undetected homicide by exhumation].

PubMed

Grellner, Wolfgang

2009-01-01

The problems of postmortem examinations and the associated dark figure of undetected homicides are well known and have been repeatedly discussed in Germany. The article deals with the case of a 73-year-old woman whose death was initially certified as being natural ("sudden cardiac death"). When secondary suspicious circumstances turned up, an exhumation was ordered three weeks after the burial. At autopsy, signs of multiple blunt force to the occiput, the thorax and the upper extremities as well as compression of the neck were found. The findings proved foreign intervention and suggested death due to suffocation. In the court trial, the accused pleaded an accidental event (fall down stairs). He was sentenced to life imprisonment for murder. The presented case of homicide remained undetected at first, as due to the deceased's advanced age a natural death had been falsely assumed. An obviously very superficial external postmortem examination by the physician was probably the main reason for the misjudgement. The factors "advanced age" and "homicide leaving few external traces and no visible injuries" seem to present special problems and essentially contribute to the dark figure of undetected homicides. Physicians performing postmortem examinations and the general public should be made aware of the problem by regular further education and discussion.

This study analyzed the forensic features of homicides in North-West Greece (Epirus) from 1998 to 2013, a borderland area between Greece and Albania. Although Greece is critically influenced by both the increasing flow of refugees and the current socioeconomic crisis, very little information has been published regarding the patterns of homicide in the country. Fifty-eight autopsied victims (36 males; 22 females) were investigated. The median age was 37 years old. The average annual homicide rate was 0.85 per 100,000 inhabitants and showed remarkable fluctuation, with largest increase during Greek financial downturn. Sixteen victims were not Greek citizens. The most common method of commitment was the use of firearm (40%). The main motives were economical causes (26%) and passion (14%). Four cases were categorized as matricide (7%), 3 as homicide-suicide (5%), 2 as patricide (3%) and 1 as infanticide (2%). Toxicological analysis proved negative for ethanol and other psychotropic substances in the majority of the victims (50%). There is an urgent need for public actions both in Epirus and in Greece, with the application of effective strategies against criminality.

2017-10-01

To analyze the completeness of precipitating circumstance information recorded in the Maryland Violent Death Reporting System and identify limitations that could affect the system's utility. We reviewed all violent deaths among Maryland residents for the years 2003 through 2014 (n = 19 161). We assessed the presence of precipitating circumstance data (abstracted from medical examiner and police reports) by manner of death and demographic characteristics. We further evaluated homicide records with multivariable regression. Demographic variation in circumstance reporting was most pronounced for homicide. Circumstances were known for 53.2% of homicide cases, and this percentage was lower among non-Latino Blacks (48.2%), males (50.7%), those aged 18 to 25 years (47.9%), those residing in jurisdictions with higher-than-average homicide rates (46.1%), and those who died outside in a public place (43.4%) or in a correctional facility (48.9%). With the exception of male gender, these factors were significantly associated with circumstance reporting when we controlled for demographic and situational variables. Circumstance reporting was least likely among groups most at risk for homicide in Maryland. Collection of circumstance data for the most affected groups should be strengthened to help develop better prevention strategies.

The purpose of this report is to identify the essential characteristics of goal-directed whole-body motion. The report is organized into three major sections (Sections 2, 3, and 4). Section 2 reviews general themes from ecological psychology and control-systems engineering that are relevant to the perception and control of whole-body motion. These themes provide an organizational framework for analyzing the complex and interrelated phenomena that are the defining characteristics of whole-body motion. Section 3 of this report applies the organization framework from the first section to the problem of perception and control of aircraft motion. This is a familiar problem in control-systems engineering and ecological psychology. Section 4 examines an essential but generally neglected aspect of vehicular control: coordination of postural control and vehicular control. To facilitate presentation of this new idea, postural control and its coordination with vehicular control are analyzed in terms of conceptual categories that are familiar in the analysis of vehicular control.

This study encompassed the total number of homicides in Bosnia and Herzegovina (B&H) in the period from 1st January 1997 to 31st December 2006 and then analysed homicidal behaviour. The aim is to assess the differences between the people who committed violent and those who committed accidental homicide in Bosnia and Herzegovina. In a multicentric, retrospective study of comparing the groups with equal number of respondents we analysed the individuals who had committed violent (n=135) and accidental homicides (n=135). The homicides were tested by using sociodemographic and psychosocial items. Measurement instruments were: General data list, Eysenck Personality Questionnaire (EPQ), Hamilton Depression Rating Scale (HDRS), Emotions Profile Index (EPI). The descriptive and multivariable logistic analysis was done statistically. In the descriptive analysis the socio-demographically violent murderers were: male gender (chi 2=3.340, P=0.009), more workers than officials (chi 2=7.340, P=0.011), fathers were more often workers/farmers (chi 2=1.430, P=0.046), gambling (chi 2=13.100, P=0.001) and possible recidivism (chi 2=6.770, a P=0.001). The accidental murderers were family people (chi 2=4.100, P=0.041), with more frequent drug abuse (chi 2=3.190, P=0.012) and they would not repeat the delict. In the multivariate analysis the violent murderers were highly discriminated (P=0.001) from accidental ones by: war involvement r=0.1148, OR=2.971 (95%), CI=1.040-7.890; age, father's education, psychoticism (EPQ) r =-0.1085, OR=0.291 (95%), CI=0.110-0870, HDRS-total r=-0.1797, OR=0.830 (95%), CI=0.710-0.930, destructiveness r=0.1270, OR=1.560 (95%), (CI=1.197-2.032, and deprivation in the P. I. E. tests. By the violence of their acts murderers confirm micro-social model of transferring the violence, and transition and heredity confirm the ecological-developmental trans-generation model of violence. Accidental murderers commit homicide in anomy, with intoxications and prolonged psycho-traumatism.

Background Prior to the establishment of the uniform drinking age of 21 in the United States, many states permitted legal purchase of alcohol at younger ages. Lower drinking ages were associated with several adverse outcomes, including elevated rates of suicide and homicide among youth. The objective of this study is to examine whether individuals who were legally permitted to drink prior to age 21 remained at elevated risk in adulthood. Methods Analysis of data from the U.S. Multiple Cause of Death files, 1990–2004, combined with data on the living population from the U.S. Census and American Community Survey. The assembled data contained records on over 200,000 suicides and 130,000 homicides for individuals born between 1949 and 1972, the years during which the drinking age was in flux. Logistic regression models were used to evaluate whether adults who were legally permitted to drink prior to age 21 were at elevated risk for death by these causes. A quasi-experimental analytical approach was employed which incorporated state and birth year fixed effects to account for unobserved covariates associated with policy exposure. Results In the population as a whole, we found no association between minimum drinking age and homicide or suicide. However, significant policy-by-sex interactions were observed for both outcomes, such that women exposed to permissive drinking age laws were at higher risk for both suicide (OR=1.12; 95% CI 1.05, 1.18, p=0.0003) and homicide (OR=1.15; 95% CI 1.04, 1.25; p=0.0028). Effect sizes were stronger for the portion of the cohort born after 1960, whereas no significant effects were observed for women born prior to 1960. Conclusions Lower drinking ages may result in persistent elevated risk for suicide and homicide among women born after 1960. The national drinking age of 21 may be preventing about 600 suicides and 600 homicides annually. PMID:22085045

Pregnancy-associated homicide and suicide in 37 US states with enhanced pregnancy surveillance.

Pregnant and postpartum women may be at increased risk of violent death including homicide and suicide relative to nonpregnant women, but US national data have not been reported since the implementation of enhanced mortality surveillance. The objective of the study was to estimate homicide and suicide ratios among women who are pregnant or postpartum and to compare their risk of violent death with nonpregnant/nonpostpartum women. Death certificates (n = 465,097) from US states with enhanced pregnancy mortality surveillance from 2005 through 2010 were used to compare mortality among 4 groups of women aged 10-54 years: pregnant, early postpartum (pregnant within 42 days of death), late postpartum (pregnant within 43 days to 1 year of death), and nonpregnant/nonpostpartum. We estimated pregnancy-associated mortality ratios and compared with nonpregnant/nonpostpartum mortality ratios to identify differences in risk after adjusting for potential levels of pregnancy misclassification as reported in the literature. Pregnancy-associated homicide victims were most frequently young, black, and undereducated, whereas pregnancy-associated suicide occurred most frequently among older white women. After adjustments, pregnancy-associated homicide risk ranged from 2.2 to 6.2 per 100,000 live births, depending on the degree of misclassification estimated, compared with 2.5-2.6 per 100,000 nonpregnant/nonpostpartum women aged 10-54 years. Pregnancy-associated suicide risk ranged from 1.6-4.5 per 100,000 live births after adjustments compared with 5.3-5.5 per 100,000 women aged 10-54 years among nonpregnant/nonpostpartum women. Assuming the most conservative published estimate of misclassification, the risk of homicide among pregnant/postpartum women was 1.84 times that of nonpregnant/nonpostpartum women (95% confidence interval, 1.71-1.98), whereas risk of suicide was decreased (relative risk, 0.62, 95% confidence interval, 0.57-0.68). Pregnancy and postpartum appear to be times of increased risk for homicide and decreased risk for suicide among women in the United States. Published by Elsevier Inc.

The relationship between state abortion-restrictions and homicide deaths among children under 5 years of age: a longitudinal study.

Sen, Bisakha; Wingate, Martha Slay; Kirby, Russell

2012-07-01

The purpose of this study is to explore whether, in the U.S., there are associations between state-level variations in mortality among young children and state abortion restriction policies - such as parental-consent requirements, parental-notification requirements, mandatory delay laws, and restrictions on Medicaid funding for abortion. To investigate this, we used NCHS Multiple Cause of Deaths public-use data files for the period 1983-2002, and compiled data on children ages 0-4 identified as having died as a result of assault/homicide in each state and year. Medicaid funding of abortion, mandatory delay laws, and parental involvement laws for minors seeking abortions were included as the main predictor variables of interest. Multivariate count data models using pooled state-year-age cohort data, with state and time fixed effects and other state-level controls, were estimated. Results indicated that, between 1983 and 2002, the average increase in the number of homicide deaths for children under 5 years of age was 5.70 per state among states that implemented stricter abortion policies over that time, and 2.00 per state for states that did not. In the count data models, parental-consent laws were associated with a 13 percent increase in child homicide deaths; parental-notification laws were associated with an 8 percent increase in child homicide deaths though the results were less robust to alternate model specifications; mandatory delay requirements were associated with a 13 percent increase in child homicide deaths. While these data do not allow us to discern precise pathways via which state abortion-restrictions can lead to more child homicide deaths, we speculate that state restrictions on abortion may result in a disproportionate increase in children born into relatively high-risk environments. Additional research is called for to explore the association of state abortion-restrictions with other measures of infant/child health and well-being. Copyright © 2012 Elsevier Ltd.

Hard Fusion Based Spectrum Sensing over Mobile Fading Channels in Cognitive Vehicular Networks

PubMed Central

Hao, Li; Ni, Dadong; Tran, Quang Thanh

2018-01-01

An explosive growth in vehicular wireless applications gives rise to spectrum resource starvation. Cognitive radio has been used in vehicular networks to mitigate the impending spectrum starvation problem by allowing vehicles to fully exploit spectrum opportunities unoccupied by licensed users. Efficient and effective detection of licensed user is a critical issue to realize cognitive radio applications. However, spectrum sensing in vehicular environments is a very challenging task due to vehicle mobility. For instance, vehicle mobility has a large effect on the wireless channel, thereby impacting the detection performance of spectrum sensing. Thus, gargantuan efforts have been made in order to analyze the fading properties of mobile radio channel in vehicular environments. Indeed, numerous studies have demonstrated that the wireless channel in vehicular environments can be characterized by a temporally correlated Rayleigh fading. In this paper, we focus on energy detection for spectrum sensing and a counting rule for cooperative sensing based on Neyman-Pearson criteria. Further, we go into the effect of the sensing and reporting channel conditions on the sensing performance under the temporally correlated Rayleigh channel. For local and cooperative sensing, we derive some alternative expressions for the average probability of misdetection. The pertinent numerical and simulating results are provided to further validate our theoretical analyses under a variety of scenarios. PMID:29415452

Fatal occupational injuries of women, Texas 1975-84.

PubMed Central

Davis, H; Honchar, P A; Suarez, L

1987-01-01

A review of Texas death certificates for 1975-84 identified 348 cases of fatal occupational injuries of civilian females. Homicides accounted for 53 per cent and motor vehicle-related injuries accounted for 26 per cent of the deaths. Injuries from firearms caused 70 per cent of the homicides. One hundred thirty-three deaths occurred to women employed in the retail trade industry; of these, 77 per cent resulted from homicide. Women workers in gasoline service stations, food-bakery-and-dairy stores, and eating-and-drinking places had especially high risks of homicide. Texas female heavy-truck drivers had the highest fatal-injury rate, with motor-vehicle-related injuries causing 89 per cent of their deaths. These results indicate that effective strategies to prevent fatal occupational injuries of Texas women will need to address the problems of workplace violence and the hazards posed by motor vehicles.

Preventing plane-assisted suicides through the lessons of research on homicide and suicide-homicide.

PubMed

Rice, Timothy R; Sher, Leo

2016-08-01

The Germanwings 9525 incident drew significant attention to the 'plane-assisted suicide' construct, yet little scientific literature exists on this topic. This paper reviews the available literature and applies lessons from the suicide-homicide and men's mental health literature to better understand this construct from a scientific perspective. A systematic review of the relevant clinical literature was undertaken. Multiple lines of evidence suggests the applicability and relevance of suicide-homicide research and men's mental health to the plane-assisted suicide phenomenon. Plane-assisted suicides occur within an overwhelmingly male, middle aged population who, in addition to suicide, commit large scale acts of murder. Issues of divorce, separation, and threats to masculinity appear integral to an effective prevention program. Further research in the understanding of plane-assisted suicide as a product of neuropsychiatric disorder may advance such prevention efforts and have the opportunity to reduce the loss of life in future tragedies.

Commentary: delusions and homicide in women--stories, old and new.

PubMed

Kelly, Brendan D

2013-01-01

It is not possible to predict homicide in an actuarial or statistical sense with any appreciable degree of accuracy. In an important and interesting study, Ferranti and colleagues highlight the centrality of religious delusions in women who kill children, consistent with the long-standing recognition that delusions are especially important in the context of violence by the mentally ill. They also note, among other findings, high rates of borderline personality disorder among female homicide offenders found not guilty by reason of insanity (60%) compared with their male counterparts (9%). As a result, the combination of religious delusions, unstable affect, access to children, and features of borderline personality disorder can usefully guide clinical decision-makers toward higher levels of treatment and follow-up, especially in women with aggressive tendencies. Despite the importance of this kind of risk stratification and treatment, however, homicide remains impossible to predict at an individual level.

Firearms, Youth Homicide, and Public Health

Levine, Robert S.; Goldzweig, Irwin; Kilbourne, Barbara; Juarez, Paul

2012-01-01

Homicide is seven times as common among U.S. non-Hispanic Black as among non-Hispanic White youth ages 15 to 24 years. In 83% of these youth homicides, the murder weapon is a firearm. Yet, for more than a decade, the national public health position on youth violence has been largely silent about the role of firearms, and tools used by public health professionals to reduce harm from other potential hazards have been unusable where guns are concerned. This deprives already underserved populations from the full benefits public health agencies might be able to deliver. In part, political prohibitions against research about direct measures of firearm control and the absence of valid public health surveillance are responsible. More refined epidemiologic theories as well as traditional public health methods are needed if the U.S. aims to reduce disparate Black-White youth homicide rates. PMID:22643459

Using a Facebook profile in determining the motive of homicide.

Ritual homicides may be affective (emotional), but usually they are premediated, instrumental, or predatory. In the case under review, the Facebook profile of the assailant helped to determine the motive of the homicide, which seemed to be ritualistic in nature. Therein, a 56-year-old male sustained 48 stab wounds and other knife injuries. On the wall in a room above the body, a pentagram was drawn with the victim's blood, followed by a few words which can be associated with a "Satanic" ritual. Searching through the Facebook profile of the culprit, Satanism as a leading motive of the homicide was eventually excluded. The most interesting point of this case was the evaluation of a sentence used as a Facebook status, which greatly contributed to confirm the paedophilic nature of the murder.

Homicide-suicides or "dyadic deaths" refer to a homicide followed by the suicide of the perpetrator within 1 week of the homicide. A unique subset is filicide-suicide: a parent kills his/her child before committing suicide. Shooting is the preferred method for both the homicide and suicide. The perpetrator has depression in most cases.We present 3 cases of filicide-suicide. In case 1, a divorced mother with schizophrenia and bipolar disorder shot her son and herself. In case 2, a father shot his son and himself while involved in a child-custody dispute. In case 3, a father, experiencing a divorce and financial difficulties, and his daughter with Angelman syndrome succumbed to carbon monoxide poisoning.The forensic pathologist should be aware of the psychosocial dynamics that interplay in filicide-suicide. Diligent attention to a parent's life stressors may aid in determining risk factors for filicide-suicide.

The Homicide-Suicide Phenomenon: Findings of Psychological Autopsies.

Homicide-suicide represents a single episode of violence which may decimate an entire family. This study aimed to further describe motives and context of these tragedies. Psychological autopsies were completed for 18 homicide-suicide cases in Dallas, Texas. This included postevent interviews with surviving family members and review of police and coroner records. Two-thirds of perpetrators had made either verbal or written threats prior to the homicide-suicide. A simplified typology describing victim-perpetrator relationship and motive type is suggested for future studies and clinical ease. Two-thirds of perpetrators fell into the category of Intimate-Possessive, most of whom were depressed men who were abusing substances and undergoing separation. Additional categories included Intimate-Ailing, Filial-Revenge, Familial-Psychotic, and Friend-Psychotic. Further, implications from this psychological autopsy study regarding risk assessment include use of collateral interviews regarding threats and past violence. © 2015 American Academy of Forensic Sciences.

Homicide-suicide is a rare and serious phenomenon which mainly occurs in intimate relationships and families. In this study ten cases of murder-suicide during the period 2006-2011 in the greater area of Düsseldorf were investigated. Data were obtained from coroner and prosecution files. All perpetrators were male. In accordance with the literature the results of the analysis revealed male sex, higher age, intimate partnership, access to firearms and special personality traits, mainly emotionally unstable, narcissistic traits and aggressiveness as the main risk factors. In all cases, at least three risk factors were identified. Breakdown of the marital relationship and social descent emerged as probable leading motives. Shooting was the most frequent method of killing followed by sharp force. Compared with homicide and suicide, homicide-suicide appears to be a distinct phenomenon. The knowledge and understanding of relevant risk factors could help mental health professionals, police and public authorities to intervene in time.

Few empirical studies have been conducted that examine the phenomenon of sexual homicide, and among these studies, many have been limited by small sample size. Although interesting and informative, these studies may not be representative of the greater phenomenon of sexual murder and may be subject to sampling bias that could have significant effects on results. The current study aims to provide a descriptive analysis of the largest sample of sexual homicide cases across Canada in the past 62 years. In doing so, the study aims to examine offender and victim characteristics, victim targeting and access, and modus operandi. Findings show that cases of sexual homicide and sexual murderers included in the current study differ in many aspects from the portrait of the sexual murderer and his or her crime depicted in previous studies. The authors' results may prove useful to the police officers responsible for the investigation of these crimes.

2015-10-01

This systematic literature review examines the effects of homicide on surviving family members, the "co-victims" or "survivors" of homicide. A content analysis was conducted on 40 articles identified through a search of the literature. The research samples were predominately located in the United States, but included two U.K. samples, one Jamaican sample, and one sample from Israel. All articles were written in English. Three themes were identified. Nineteen articles explored the psychological, academic, social, occupational, and familial effects of homicide. Thirteen articles considered survivors' grieving process and how it was altered by experiences with the criminal justice system as well as coping strategies used by survivors to deal with their grief. Eight articles explored treatment interventions available to help surviving family members deal with their grief. Key findings from the articles, limitations of the current research, and implications for future research, policy, and practice are included. © The Author(s) 2014.

Sexual homicide by a juvenile offender occurs approximately 9 times per year in the United States. Little is known about the post-incarceration adjustment of these offenders. The current study was designed to follow up 30 years later on a sample of eight adolescent sexual homicide offenders who were convicted of murder and sentenced to adult prison. The results indicated that six out of eight offenders were released from prison, and their mean sentence length was 12 years and 2 months. Four offenders out of the six released were rearrested, but none of the arrests were for homicide, sexual or otherwise. The post-incarceration arrests were for violent, drug-related, and property crimes, as well as possession of a firearm. Three out of the four recidivists have been recommitted to prison. Implications concerning the comparability of results to past research, time served in prison, and types of post-release offenses are discussed. © The Author(s) 2014.

This retrospective study analyses post-mortem examination data of 251 homicide victims recorded by the Brescia Institute of Forensic Medicine between the years 1982 and 2012. The following variables were considered: year, month and day of death; gender, age and nationality of the victim; type of injurious mean; cause of death; homicide-suicides events; multiple murders; scene of death; toxicological data. Victims were usually young (30% was in the 21-30 years class) and males (64%). Although the victims were mostly Italians (73%), from 1990's more and more foreign victims appeared, following the migratory flow that affected Brescia County. The offenders frequently used firearms to kill their victims (41%), in particular for multiple murders. Sharp instruments were used mostly by foreigners. The study also emphasized 20 homicide-suicide events, mostly committed between intimates and family members. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Objective To identify gender differences in violent deaths in terms of incidence, circumstances, and methods of death. Design Analysis of surveillance data. Setting North Carolina, a state of 8.6 million residents on the eastern seaboard of the US. Subjects 1674 North Carolina residents who died from violence in the state during 2004. Methods Information on violent deaths was collected by the North Carolina Violent Death Reporting System using data from death certificates, medical examiner reports, and law enforcement agency incidence reports. Results Suicide and homicide rates were lower for females than males. For suicides, females were more likely than males to have a diagnosis of depression (55% v 36%), a current mental health problem (66% v 42%), or a history of suicide attempts (25% v 13%). Firearms were the sole method of suicide in 65% of males and 42% of females. Poisonings were more common in female than male suicides (37% v 12%). Male and female homicide victims were most likely to die from a handgun or a sharp instrument. Fifty seven percent of female homicides involved intimate partner violence, compared with 13% of male homicides. Among female homicides involving intimate partner violence, 78% occurred in the woman's home. White females had a higher rate of suicide than African‐American females, but African‐American females had a higher rate of homicide than white females. Conclusions The incidence, circumstances, and methods of fatal violence differ greatly between females and males. These differences should be taken into account in the development of violence prevention efforts. PMID:17170164
