    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.

    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.

  3. Change and Stability in the Characteristics of Homicide Victims, Offenders and Incidents During Rapid Social Change.

    The Russian homicide rate doubled during the 1990s and is now among the highest in the world. During this same period, Russian citizens experienced swift, widespread, and meaningful political, economic, and social change. It is likely that this profound transition altered structural conditions, cultural norms, and interpersonal relations in a way that led to changes in the nature of interpersonal violence. Taking advantage of a unique set of homicide narratives drawn from court and police records in the Udmurt Republic, this study examined stability and change in the distribution of Russian homicide victim, offender, and incident characteristics before and after the fall of the Soviet Union. Odds ratios obtained from logistic regression showed no change in victim characteristics, but substantial changes in several offender and incident characteristics. We discuss the potential mechanisms through which the structural and cultural shifts are resulting in these changes and conclude that the ongoing transition is largely responsible for the changing nature of homicide in Russia. In doing so, we introduce the new term "criminological transition" and suggest that Russia (and perhaps other nations) may have experienced a change in its crime profile in much the same way as we discuss a "demographic transition" in terms of fertility and mortality profiles.

    Using data from the North Carolina Violent Death Reporting System and other sources, we examined ecologic relationships between county (n = 100) disadvantage and intimate partner homicide (IPH), variability by victim gender and county urbanicity, and potential mediators. County disadvantage was related to female-victim homicide only in metropolitan counties (incidence rate ratio [IRR] 1.25); however, disadvantage was associated with male-victim IPH regardless of county urbanicity (IRR 1.17). None of the potential intervening variables examined (shelter availability, intimate partner violence services' funding) was supported as a mediator. Results suggest disparities across North Carolina counties in IPH according to county disadvantage. Future research should explore other potential mediators (i.e., service accessibility and law enforcement responses), as well as test the robustness of findings using additional years of data.

  6. 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.

  7. Psychopathic traits in Finnish homicide offenders with schizophrenia.

    There is a paucity of studies examining psychopathy in comparable samples of violent individuals with and without psychotic illness. The main goal of the study was to assess the prevalence and nature of psychopathic traits as measured by PCL-R among Finnish homicide offenders with schizophrenia. Further, the impact of co-morbid psychopathy on the homicidal incidents, as well as the associations of psychopathy and offender background factors, among offenders with schizophrenia was investigated. A retrospective study was performed using extensive forensic psychiatric evaluation reports and crime reports as sources of information. The sample consisted of 72 homicide offenders with schizophrenia and 72 controls without psychotic illness. Psychopathic features were prevalent among Finnish homicide offenders with schizophrenia, although for the most parts to a lesser extent compared to other homicide offenders. Like non-mentally ill psychopathic offenders, offenders with schizophrenia and many psychopathic traits are likely to present early starting problems in many areas of life and they also commit homicides that resemble other psychopathic offenders' in their choice of victims, intoxication and post-offense behavior. The observed prevalence of psychopathic traits highlights the importance of psychopathy assessment among violence-prone individuals with schizophrenia. In most respects, offenders with schizophrenia and high levels of psychopathic traits seem to be similar to psychopathic offenders without psychotic illness, which has implications for early intervention and management.

    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.

  9. Commentary: Homicide-suicide in older adults--cultural and contextual perspectives.

    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.

    Limited information exists on juvenile homosexual homicide (JHH), that is, youths who perpetrate sexual homicides against same-sex victims. Only a handful of cases from the United States and internationally have been described in the literature. This study, the first of its kind, examines the epidemiology, victimology, victim-offender relationship, and weapon-use patterns in JHH offenders using a large U.S. database on homicide spanning three decades. The data for this study were derived from the Federal Bureau of Investigation's Supplementary Homicide Reports (SHRs) for the years 1976 through 2005. A total of 93 cases of JHH were identified. On average, three of these crimes occurred annually in the U.S., and there was a marked decline in its incidence over the study period. Ninety-five percent were male offender-male victim cases and 5% were female offender-female victim cases. JHH offenders were over-represented amongst all juvenile sexual murderers, similar to their adult counterparts. The majority of these boys were aged 16 or 17 and killed adult victims. They were significantly more likely to kill adult victims than other age groups, to be friends or acquaintances of the victims, and to use contact/edged weapons or firearms. Most offenders killed same-race victims, although Black offenders were significantly more likely than White offenders to kill interracially. A case report is provided to illustrate JHH. Further research is needed to promote our understanding of the pathogenesis, etiology, and associated risk factors for this aberrant form of murder by children.

  11. Is serial homicide really increasing?

    PubMed

    Schlesinger, L B

    2001-01-01

    Close examination of the available crime data reveals little scientific support for the widely held belief that serial homicide is frequent and increasing. The author argues that the dramatic changes in homicide clearance rates, incidence of murders with unknown motives, and victim gender data point to a likely increase, not in serial murder, but in contract murder. This type of killing appears to be having a significant impact on society; yet there has been a complete absence of forensic psychiatric study of this crime, a circumstance that needs to change.

    2000-01-01

    Seven cases of mass homicide in Australia, New Zealand, and Britain between 1987 and 1996 are presented. These cases add to the world literature on these rare crimes and balance previous, mostly North American reports. These acts were committed by socially unsuccessful, self-absorbed, and resentful individuals. Lengthy fantasy comprising identification, modeling, and rehearsal preceded the incidents, even where the final acts had impulsive elements. Most had a long-standing fascination with firearms fueling their fantasies and providing the means for mass killing. Their targets were mostly unprotected strangers. Overt suicidal intent or a preparedness to die while committing the homicides was invariable. Ethological theories of status acquisition may provide a useful understanding of mass homicide.

    Homicides followed by the suicide of the perpetrator constitute a serious form of interpersonal violence. Until now no study has directly compared homicide-suicides to other violent deaths from multiple countries, allowing for a better understanding of the nature of these violent acts. Using country-specific data, this study describes and compares the incidence and patterns of homicide-suicide as well as the relationship between homicide-suicide, homicide, suicide and domestic homicide in the Netherlands, Switzerland and the United States. The results indicate that cross-nationally, homicide-suicides are more likely than other types of lethal violence to involve a female victim, multiple victims, take place in a residential setting and to be committed by a firearm. Although homicide-suicides display many similarities across the different countries, differences exist regarding age and the use of firearms in the offence. This study indicates that homicides followed by suicides differ from both homicides and suicides in similar ways internationally. Cross-national differences in the availability of firearms may explain the international variation of homicide-suicide rates and patterns.

    Homicide continues to be a problematic public health concern, but homicide rates have dropped considerably since the mid-1980s. This article proposes that the decrease in violence was caused by a large number of national and local violence prevention initiatives. Homicide and violence data are reviewed and the developmental dynamics of violence and homicide are discussed, noting the different tracks youth take toward violence. The risk factors that lead youth toward a violent lifestyle are compared with the protective factors that shield them from it. The principles involved in the prevention of violent behavior such as homicide are also discussed.

    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.

    The medicolegal and subsequent criminologic interpretation of forensic and pathological findings in cases of homicide makes up an important tool of case profiling. In a retrospective study of 26 cases of "multiple homicides" involving 31 perpetrators (30 males, 1 female, mean age 33.5 years) and 73 victims (33 males, 40 females, mean age 36 years, 68 fatalities, 5 survivors), autopsy reports and prosecution authorities' files were investigated with regard to individual characteristics of victims and offenders, circumstances as well as mode of commitment. The major aim of this study was to comprehensively elucidate and characterise relevant forensic and criminologic features, which may gain importance for forensic case profiling. Forty-six victims were found in the close social environment of the perpetrator and 45 homicides were committed either in the victim's, the perpetrator's or the shared domicile. The main motives included concealment of a crime (n=13), personal conflicts/domestic arguments (n=7) and greed (n=12). The relevant injuries with regard to the cause of death were attributable to sharp force (n=13), blunt force (n=7), gunshot wounds (n=24), ligature strangulation (n=3), smothering (n=5), fire/carbon monoxide (n=4) and combined impacts (n=11). In 15 cases, so called defence injuries were found. In 5 victims a post-mortem blood alcohol concentration >1.5 g/l was determined. In six perpetrators, a severe psychiatric impairment of juridical responsibility was ascertained (Section 20 German criminal code, n=2, psychosis; Section 21 German criminal code, n=4, acute alcohol intoxication). As far as conviction data were available, 27 crimes were juridically assessed as murder, 12 as manslaughter and one as bodily harm with fatal consequences.

    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.

    OBJECTIVE: to describe mortality from homicides in Itabuna, in the State of Bahia. METHOD: 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. RESULTS: 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. CONCLUSIONS: 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.

    Murder-suicide, homicide-suicide, and dyadic death all refer to an incident where a homicide is committed followed by the perpetrator's suicide almost immediately or soon after the homicide. Homicide-suicides are relatively uncommon and vary from region to region. In the selected literature that we reviewed, shooting was the common method of killing and suicide, and only 3 cases of homicidal hanging involving child victims were identified. We present a case of dyadic death where the method of killing and suicide was hanging, and the victim was a young woman.

    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.

    Hu, Guoqing; Webster, Daniel; Baker, Susan P

    2008-07-01

    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.

    Publications from the midwestern region of the United States have demonstrated an incidence of 14-23% of painless thyroiditis in hyperthyroid individuals. This possibly could represent a local phenomenon, and perhaps is not typical for other areas of the country. The 24 hour radioactive iodine uptakes in 152 consecutive hyperthyroid individuals in the Philadelphia area were evaluated. No patient in the series, with clinical and biochemical evidence of hyperthyroidism, had painless thyroiditis. It is concluded that the incidence of painless thyroiditis is markedly lower in the Philadelphia area than in the Midwest regions of the United States.

    The aim of this study was to identify trends in the incidence of lung cancer in the Leon Healthcare Area. All cases of cancer among residents of the Leon healthcare catchment area listed in the hospital-based tumor registry of the Centro Asistencial Universitario de Leon (CAULE) between 1996 and 2010 were included. Gross incidence rates over 3-year intervals were calculated and adjusted for the worldwide and European populations. A total of 2,491 cases were included. In men, incidence adjusted for the European population rose from 40.1 new cases per 100,000 population (1996-1998) to 61.8 (2005-2007), and then fell to 54.6 (2008-2010). In women, incidence tripled from 3.0 (1996-1998) to 9.2 new cases per 100,000 (2008-2010). Although lung cancer is an avoidable disease, it is a serious problem in the Leon Healthcare Area. Of particular concern is the rising incidence among women.

  8. Homicide during postictal psychosis

    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. PMID:25667886

The results of this unique descriptive study of necrophilia associated with sexual homicide provide information on crime-scene locations, methods of killing, body disposition, premortem sexual assault, specifics of the necrophilic acts, methods of victim abduction, and motivational dynamics. The findings suggest that the most common explanation for necrophilia-the offender's desire to have an unresisting partner-may not always be applicable in cases where this rare paraphilia is connected to sexual murder. The possibility of using crime-scene behaviors in these cases to investigate serial sexual murders is offered.

    OBJECTIVE To evaluate the risk of homicide in Rio de Janeiro’s favelas, taking into account the territorial disputes taking place in the city. METHODS The study is based on data on mortality from homicide in the city of Rio de Janeiro between 2006 and 2009. Risks in favelas and in surrounding areas were evaluated, as was the domination of armed groups and drug dealing. Geographic and ethnographic concepts and methods were employed, using participant observation, interviews and analysis of secondary data on health. RESULTS Within the favelas, mortality rates from homicide were equivalent to, or lower than, the rest of the city, although they were considerably higher in areas surrounding the favelas, especially in areas where there was conflict between armed rival gangs. CONCLUSIONS The presence of trafficking crews and turf war in strategic areas of the city increases homicide rates and promotes the “ecology of danger” in these areas. PMID:24789642

    Rates of homicide among African Americans are much higher than those of other racial or ethnic groups. Research has demonstrated that homicide can be psychologically debilitating for surviving family members. Yet, exploring the experiences of homicide victims’ surviving loved ones has received little attention. This study examined the coping strategies of African American survivors of homicide. Qualitative interviews were conducted with 8 African American family members (ages 18-82) of homicide victims. Survivors were recruited from the Massachusetts Office of Victim Services and from homicide survivor support, school, and community groups throughout the New England area. Interviews were conducted using open-ended questions derived from coping, support network, grief, and bereavement literatures. Results indicate that the primary coping strategies utilized by African American survivors of homicide victims are spiritual coping and meaning making, maintaining a connection to the deceased, collective coping and caring for others, and concealment. Implications for research and practice are discussed.

    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.

    The present study describes regional variations in homicide rates in Jalisco State, Mexico, in 1989-1991, 1994-1996, and 1999-2000, analyzing the trends by gender and socioeconomic stratum. Using mortality data generated by the National Institute for Statistics, Geography, and Information Technology, homicide rates adjusted by age and gender were calculated, along with rate/female rate ratios; rate ratios by socioeconomic stratum and 95% confidence intervals were also calculated. According to the results, the homicide rate showed: a downward trend in the 1990s; a regional homicide mortality pattern, with the highest rates in peripheral regions, considered among the poorest areas in the State; municipalities with the lowest socioeconomic conditions also presenting a statistically significant excess homicide mortality; and an evident over-mortality from homicide among males. The results point to tasks and challenges for public health and law enforcement institutions, including the need to implement different inter-institutional policies that take into consideration the characteristics of homicide and violent crime in Jalisco.

    Homicidal burning of married women in India is a major concern for the Government, law-enforcing authorities, the judiciary, the police and medico-legal experts all over the country who are associated with dowry disputes. Dowry death, a heinous crime, is gradually engulfing and polluting the entire society. Sections 304(B) and 498(A) of the Indian Penal Code (IPC) have been introduced and Sections 174 Criminal Procedure Code (Cr PC) and 176 Cr PC have been modified but, instead of deterring dowry deaths, the occurrences are increasing day by day and the number of cases coming for post-mortem examination is rising. Both parties, that is, the parents and in-laws of the deceased, are becoming adept at manufacturing circumstantial evidence to serve their own interests. Therefore, to establish the truth and for the smooth administration of justice, reliable unbiased medical evidence has to be corroborated. This study presents retrospective research carried out in the tertiary care teaching hospital of MKCG Medical College, Berhampur, Eastern India, for a five-year period between January 1998 to December 2002. From a total of 58 burned wives, 32 (55.1%) were homicidal burns. These cases were analyzed in view of epidemiological and medico-legal aspects. The majority of the affected women (90.63%) were in the 18 to 26 years of age group. Death occurred within the first few years of marriage and most of them had no children. All the victims belonged to the Hindu religion and 62.5% of incidents occurred during the daytime. In 71.87% cases the incident occurred in rural areas. Eighty-three per cent of cases occurred in a joint family within the house. In most cases, kerosene was the accelerant and flame was the causative agent. In more than 68.75% of cases the total body surface area involved was more than 80%. Most victims died at the time of the incident, or within the subsequent 24 hours, due to hypovolumeic shock. The education status in 70.21% cases was either illiterate

    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.

    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.

    Arsenic-induced deaths have been known to occur from accidental poisoning, as a result of medical therapy, and from intentional poisonings in homicide and suicide. Twenty-eight arsenic deaths in North Carolina from 1972 to 1982 included 14 homicides and seven suicides. In addition, 56 hospitalized victims of arsenic poisoning were identified at Duke Medical Center from 1970 to 1980. Four case histories of arsenic poisoning in North Carolina are presented and clinical manifestations are discussed. In view of the continued widespread use of arsenic in industry and agriculture, and its ubiquity in the environment, arsenic poisoning will continue to occur. A need for knowledge of its toxicity and of the clinical manifestations of acute and chronic arsenic poisoning will also continue.

    As with other sexual offenders, sexual homicide perpetrators can be reluctant to talk about their criminal behavior. Therefore, in homicide cases, forensic practitioners frequently rely on crime scene information to identify any sexual behavior associated with the offense. This study aims to identify objective and readily available crime scene information, alongside information about victims and perpetrators, based on 65 cases from England and Wales in the United Kingdom of men convicted of homicide who had committed a non-serial sexual homicide and 64 cases of men convicted of homicide where the available evidence indicated that it was a non-serial non-sexual homicide. Chi-square tests and logistic regression were used to analyze the data. There were few differences in terms of demographic information and criminal histories between the two perpetrator groups. There were crime scene indicators supporting the use of Ressler et al.'s definition of sexual homicide. The victims of sexual homicide were generally found in their home with the lower half of the body exposed and with evidence of vaginal sex. Furthermore, extreme injuries and strangulation were more frequent in sexual homicides. Use of weapon was associated with a non-sexual homicide. Victims of sexual homicide were as likely to know the perpetrator as not. Potential benefits of the characteristics reported to investigators and forensic practitioners tasked with identifying sexual homicides are discussed and areas for further research suggested.

    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.

    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.

    Methane is a suffocating gas, and "methane deaths" are largely the result of suffocation by gas-air displacement after accidental or deliberate exposure. Neither methane gas nor other suffocating gases are a common means of homicide, with the potential exception of the use of gas in chemical weapons or gas chambers. Here, we report the case of a 53-year-old woman who was killed by her husband with methane gas. The man had given his wife a dose of Lorazepam before setting up a hose that conveyed methane from the kitchen into the apartment's bedroom. The man subsequently faked his own suicide, which was later discovered.

    Paranoia is a mental pathology which severely complicates interpersonal relationships. Its mechanisms and its delusional themes often mean that paranoid subjects have strained, or even violent relations inside and/or outside their family. These difficuIt relationships can sometimes even lead to serious assaults without causing death or more rarely result in homicides with frequent pre-incident indicators.

    Using Riedel and Zahn's 1994 reformatted version of an FBI database, the mean age of homicide victims in 2,175 homicide-suicides (4,350 deaths) was compared with that of all other victims of homicides reported for the USA from 1968 to 1975. The overall mean age of homicide victims in homicide-suicides was 1 yr. greater than for victims of homicides not followed by suicides, whereas the mean age for both male and female homicide-suicide victims was, respectively, 3 yr. less and greater than the other homicide victims. The mean age of Black homicide victims of homicide-suicides was 2.4 yr. less than that for Black victims of other homicides, whereas the means for Black and White male homicide victims in homicide-suicides were, respectively, about 4 and 5 yr. less than for victims of other homicides. Also, the mean age of White female homicide victims in homicide-suicides was more than two years greater than for female victims of homicides not followed by suicides. When both sex and race were considered, the mean age for those killed in homicide-suicides relative to those killed in homicides not followed by suicides may represent subpopulations with different mean ages of victims.

    2012-07-01

    This study analyzes homicide incidence per municipality (county) in Brazil in the year 2008. The authors estimate and compare homicide rates according to different methods, finding evidence that depending on the method employed, the results can differ significantly, especially for small municipalities. Bayesian spatial procedures were employed, allowing minimization of variation in the rate estimates. The methods consider a priori distributions and information on contiguity of municipalities. According to the findings, the impact of corrective procedures is not relevant for large municipalities, but such estimates present significant differences for small municipalities. Comparing the different estimates, the authors conclude that there may be distortions in the rates published in the literature. To overcome such potential distortions, it is necessary to take the main goal in each analysis into account. When the emphasis is on overall visualization of the homicide phenomenon, the best option is spatial corrections. However, to obtain more accurate local estimates, Bayesian methods are more appropriate.

    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.

    A review of Texas death certificates for 1975-84 identified 779 civilian males whose deaths were homicides that occurred in the workplace. Injuries from firearms caused 81 per cent of the deaths. The overall rate of workplace homicide was 2.1/100,000 male workers/year. Males employed in taxicab service had the highest rate of workplace homicide. 78.2/100,000 male workers/year. Males employed in certain retail trade industries, law enforcement, and the private-security industry also had high rates of workplace homicide. Male workers greater than or equal to 65 years old were at especially high risk, with a workplace-homicide rate 3.5 times that of younger workers. A review of medical examiners' records in five urban counties indicated that 32 per cent of victims who had worked in eating-and-drinking places and 5 per cent of other workers had blood or cerebrospinal-fluid alcohol levels greater than or equal to 0.10 g/dl. These results provide a base for designing effective strategies to prevent workplace homicides.

    Widespread awareness of the recent deaths of several black males at the hands of police has revealed an unaddressed public health challenge-determining the root causes of excessive use of force by police applied to black males that may result in "justifiable homicides." The criminalization of black males has a long history in the USA, which has resulted in an increase in policing behaviors by legal authorities and created inequitable life chances for black males. Currently, the discipline of public health has not applied an intersectional approach that investigates the intersection of race and gender to understanding police behaviors that lead to "justifiable homicides" for black males. This article applies the core tenets and processes of Public Health Critical Race Praxis (PHCRP) to develop a framework that can improve research and interventions to address the disparities observed in recent trend analyses of "justifiable homicides." Accordingly, we use PHCRP to offer an alternative framework on the social, legal, and health implications of violence-related incidents. We aim to move the literature in this area forward to help scholars, policymakers, and activists build the capacity of communities to address the excessive use of force by police to reduce mortality rates from "justifiable homicides."

    Research on covictims, family members, and close friends who have lost loved ones to intimate partner homicide (IPH) is a neglected area of study. We conducted phenomenological interviews with covictims to gain insights into risk and lethality, examined affidavits from criminal case files, and reviewed news releases. The data uncovered acute risk factors prior to the homicide, identified changes in the perpetrators' behavior and the perpetrators' perceived loss of control over the victim, and described barriers that victims faced when attempting to gain safety. Findings suggest that recognizing acute risk factors is an important area for future IPH research.

    Background Although data are sparse, it has been estimated that the highest rates of homicide death amongst children are in Africa. Little information is available on ages 0 -< 15 years. No reliable quantitative surveillance analysis of neonaticide (killed at less than one week) has been done. Methods A Violent Death Survey following WHO/CDC Guidelines was completed in Dar es Salaam region, Tanzania (DSM) (population 2.845 million) in 2005. Qualitative and quantitative data were gathered and analyzed using mixed methods techniques. Results The overall age adjusted rate of discarded and killed children in DSM was 2.05. The rate of neonaticide was 27.7 per 100,000) while the rate of homicide incidence for children > one day was Discussion The overall estimated homicide rate for Africa of children under age 15 was 4.53 per 100,000, whereas. The estimated global rate is 1.7 per 100,000 closer to DSM‘s rate. The results in DSM show that broad age groupings such as ” <1 year” or “0–4 years” or “0 – <15 years” may mask a high incidence of neonaticide and an otherwise low incidence of murdered children. The print media provided good in-depth coverage for a few cases but it is not known if the reported cases are representative. Conclusion Eighty percent of homicides of children in DSM are neonaticides. Since it is believed that the forces behind neonaticide are fundamentally different than homicides of older children, it is suggested that data of future surveys be parsed to include neonates, until the phenomenon is more clearly understood and addressed. Further understanding of the mother and father of the deceased is needed. Continued surveillance data collection is important to expand the sample size. PMID:22066333

    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].

    In this study we investigated homicides in the two Scandinavian capitals, Copenhagen, Denmark and Oslo, Norway, for the 10-year period from 1985 to 1994. The total number of homicides was 431; 63.8% occurred in Copenhagen and 36.2% in Oslo. The average homicide rate was 1.6/100,000 in Copenhagen and 1.8/100,000 in Oslo. Blunt force, sharp force, and strangulation were the most common methods. Firearms were also used but did not account for >20% in either of the two cities. This is probably due to strict gun laws in both countries. There was no clear difference between the homicide victim populations in the two cities with regard to age, gender, or social and marital status. The proportion of alcoholics and unemployed persons was much higher than in the background population and to a similar extent in both cities, indicating that the homicide victim populations differ from the background populations. The perpetrator knew the victim in the majority of the cases. The most frequent motives or circumstances in both cities were fights, family rows, financial controversies, or jealousy.

    Purpose We report the rare case of a patient with intractable epilepsy and escalating aggression, resulting in murder, who had complete resolution of her seizures and explosive behavior following a right temporal lobectomy. Patients and methods We searched the available literature from 1880 to 2013 for cases of epilepsy being used as a court defense for murder and collected information regarding the final sentencing outcomes. We selected 15 papers with a total of 50 homicides. Results We describe the case of a 47-year-old woman with drug-resistant right temporal epilepsy who developed increasing emotional lability, outbursts of anger and escalating violent behavior culminating in a violent murder. The patient was imprisoned while awaiting trial. In the interim, she underwent a successful temporal lobectomy with full resolution of seizures, interictal rage and aggressive behaviors. After the surgery, her charges were downgraded and she was transferred to a psychiatric facility. Conclusion The aggressive behavior associated with epilepsy has been described in the literature for over a century. A link between epilepsy and aggression has been disproportionally emphasized. These patients share some common characteristics: they are usually young men with a long history of epilepsy and lower than average intelligence. The violent act is postictal, sudden-onset, more likely to occur after a cluster of seizures and is usually related with alcohol abuse. PMID:23700367

    Serial sexual homicide has been the object of intensive study from forensic psychiatric, criminological, developmental, and sociological perspectives. In contradistinction to these approaches, neuropsychiatric concepts and methods have received relatively little attention in this area. In this article we adopt a neuropsychiatric developmental perspective and undertake a review of the psychiatric literature on violence and autism spectrum disorders. Our analysis of this literature suggests the presence of an association between autism spectrum psychopathology and serial homicidal behavior. Recommendations for further research to help clarify the nature of this association are briefly discussed.

    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

  8. Pride and Purpose as Antidotes to Black Homicidal Violence

    PubMed Central

    Thomas, Charles W.

    1987-01-01

    The incidence of black male homicide is a major public menace. The lowest incidence of black male homicide was when the black power movement was visible and flourishing. Psychohistorical data support the contention that racial pride is an effective means for regulating intragroup tensions. In the absence of an Afrocentric orientation that promotes community power and self-determination, the need for self-reliance is eroded by value illnesses. The value orientation of the black movement supplied the pride used to obtain academic success, to reduce juvenile delinquency, and to help Afro-Americans to structure their lives for personal satisfactions. Blackness has always been about personal power and social control, but society does not allow much access to either for Afro-Americans. As a consequence, stress from racism is severe, asymptomatic, and multi-faceted. The best antidote to black homicidal violence comes from a pro-social effort based upon a self-image that gives a feeling of positive accomplishment and appreciation. Afrocentric pride promotes or enhances pro-social behavior. PMID:3560242

    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.

    Public concern with societal violence is intensified when persons who have been found not guilty by reason of insanity (NGRI) of having committed a homicide or serious assault are returned to the community. Successful management of such acquittees in the community requires a sophisticated understanding of the person and the illness within the larger context of the violent incident, the family, the community, and the culture. In this article, we present an analysis of psychotic violence within a family context. A qualitative study of 64 subjects who were found NGRI of killing or seriously injuring a family member resulted in four prototypes of intrafamilial homicide/assault: Till Death Us Do Part; Overwhelming Burden, Elimination of the Limit Setter; and Family-Focused Delusional Killing. The prototypes are presented as a model for developing management strategies both for future risk assessment and for successful transition of the insanity acquittee into the community.

    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.

  12. The narrative dynamics of grief after homicide.

    Rynearson, Edward K

    2012-01-01

    The homicidal death of a loved one is horrific. Dying from homicide can be more sudden, frightening, and stigmatizing than natural dying and may be followed by a sub-type of prolonged grief complicated by vivid narrative reenactment of the dying, intense feelings of remorse, and nihilistic despair. After a literature review of grief after homicide, the author clarifies the salient narrative themes of homicidal dying and their specific effects on trauma and separation distress. A preliminary model is then developed and illustrated in a therapy case outlining a technique (imaginative exposure) to diminish the disabling fixation of reenactment imagery, remorse, and despair.

    Background: In many countries gastric cancer has the highest incidence among the gastrointestinal cancers and is the second most common cancer in Iran. The aim of this study was to identify and map high risk gastric cancer regions at the county-level in Iran. Methods: In this study we analyzed gastric cancer data for Iran in the years 2003-2010. Areato- area Poisson kriging and Besag, York and Mollie (BYM) spatial models were applied to smoothing the standardized incidence ratios of gastric cancer for the 373 counties surveyed in this study. The two methods were compared in term of accuracy and precision in identifying high risk regions. Result: The highest smoothed standardized incidence rate (SIR) according to area-to-area Poisson kriging was in Meshkinshahr county in Ardabil province in north-western Iran (2.4,SD=0.05), while the highest smoothed standardized incidence rate (SIR) according to the BYM model was in Ardabil, the capital of that province (2.9,SD=0.09). Conclusion: Both methods of mapping, ATA Poisson kriging and BYM, showed the gastric cancer incidence rate to be highest in north and north-west Iran. However, area-to-area Poisson kriging was more precise than the BYM model and required less smoothing. According to the results obtained, preventive measures and treatment programs should be focused on particular counties of Iran.

    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.

    2014-01-01

    This study aimed to assess the female homicide rate due to aggression in Rio Grande do Sul, Brazil, using this as a "proxy" of femicide. This was an ecological study which correlated the female homicide rate due to aggression in Rio Grande do Sul, according to the 35 microregions defined by the Brazilian Institute of Geography and Statistics (IBGE), with socioeconomic and demographic variables access and health indicators. Pearson's correlation test was performed with the selected variables. After this, multiple linear regressions were performed with variables with p < 0.20. The standardized average of female homicide rate due to aggression in the period from 2003 to 2007 was 3.1 obits per 100 thousand. After multiple regression analysis, the final model included male mortality due to aggression (p = 0.016), the percentage of hospital admissions for alcohol (p = 0.005) and the proportion of ill-defined deaths (p = 0.015). The model have an explanatory power of 39% (adjusted r2 = 0.391). The results are consistent with other studies and indicate a strong relationship between structural violence in society and violence against women, in addition to a higher incidence of female deaths in places with high alcohol hospitalization.

    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

  5. Mutilation in Korean Homicide: An Exploratory Study.

    PubMed

    Sea, Jonghan; Beauregard, Eric

    2016-08-15

    Mutilation is a rare and unusual act performed on a victim, especially in cases of homicide. Knowledge on mutilation homicide is scarce as the base rate of this type of homicide is very low. Moreover, previous studies examining this specific criminal behavior have been mainly descriptive, neglecting to look at other factors related to the act of mutilation. Furthermore, depending on the cultural context and country of origin, the infliction of mutilation pre-, per-, or post-homicide translates into different meanings. Therefore, it is important to examine mutilation homicide in the context of non-Western countries. Using crime and forensic examination reports subjected to forensic examination and convicted for a homicide between 1995 and 2011 (N = 1,200) in Korea, the rate of mutilation homicide was estimated. Based on the 65 cases (5.4%) identified, information on the offenses and offenders were described. Moreover, using a series of bivariate analyses, the current study compared cases of mutilation homicides in Korea with other countries. Findings revealed interesting differences and similarities between mutilation homicide cases from Korea and the other countries. For instance, offender-victim relationship, victim's gender, and criminal history were significantly different from the comparison groups. In addition, compared with Korea, mutilation homicide cases were significantly more likely to involve an accomplice in Finland, suggesting the need to carry the body over a long distance. Investigators and researchers need to understand the cultural context in which these acts are committed as the infliction of mutilation may serve different purposes across different countries.

  6. Domestic homicide followed by parasuicide: a comparison with homicide and parasuicide.

    2009-10-01

    Homicide-suicides are a rare yet very serious form of interpersonal violence that occur mainly in partnerships and families. As both perpetrator and victim die in a homicide- suicide, data sources in previous studies typically lack detailed information. This study overcomes this limitation by making use of homicides followed by a suicide attempt of the perpetrator (homicide-parasuicides). The authors examine to what extent these homicide-parasuicides can be understood as being primarily an expression of homicidal or of suicidal behavior. In total, 77 homicide-parasuicides are compared to 430 homicides and 161 parasuicides. The results show that homicide-parasuicides constitute a different category of lethal violence with regard to demographic, individual, and event-related characteristics. Subanalyses of homicide-parasuicides involving women and children reveal similar differences. The finding that a large majority of the perpetrators were mentally ill, dependent on the victim, and killed when faced with separation from the victim may suggest that increased monitoring of this group might have preventive value.

    2013-12-10

    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.

    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.

    Serious offenses against persons perpetrated by juveniles raise fundamental questions about the background, causes, and prevention of future crime. The current study addresses the potential of future crime of all juvenile homicide offenders (JHOs) in the Netherlands in the period 1992-2007. In contrast to former research on recidivism of JHOs, which has been merely descriptive, the present study integrates theoretical perspectives as to why some of these juveniles turn back to crime, while others do not. To this end, relationships are investigated between recidivism behavior and risk factors. Results indicate that male JHOs, and JHOs who maintain relationships with delinquents, run a greater risk of reoffending.

    2010-07-01

    Homicide is one of the leading causes of death in Los Angeles County and is known to be elevated in low-income urban neighborhoods and in black males. However, because homicide occurs primarily among young adults, mortality rate statistics may underrepresent its importance. We estimated the impact of homicide on life expectancy by demographic group and geographic area in Los Angeles County, 2001-2006. Life expectancy estimates were calculated using mortality records and population estimates for Los Angeles County. Cause elimination techniques were used to estimate the impact of homicide on life expectancy. Homicide was estimated to reduce life expectancy by 0.4 years for Los Angeles County residents and by 2.1 years for black males. The impact of homicide on life expectancy was higher in low-income neighborhoods. In some low-income urban neighborhoods, homicide was estimated to decrease life expectancy in black males by nearly 5 years. Homicide causes substantial reductions in life expectancy in Los Angeles County. Its impact is magnified among black males and in low-income urban areas, underscoring the need for homicide reduction in urban centers.

    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

    2015-01-01

    Homicide-suicide incidents involving child victims can have a detrimental impact on survivors of the violence, family members and friends of the decedents, and other community members, but the rare occurrence of these acts makes using quantitative data to examine their associated antecedents challenging. Therefore, using qualitative data from the 2003–2011 National Violent Death Reporting System, we examined 175 cases of homicide-suicide involving child victims in an effort to better understand the complex situational factors of these events. Our findings indicate that 98% of homicide-suicides with child victims are perpetrated by adults (mostly parents) and propelled by the perpetrators’ intimate partner problems, mental health problems, and criminal/legal problems. These events are often premeditated, and plans for the violence are sometimes disclosed prior to its occurrence. Findings provide support for several theoretical perspectives, and implications for prevention are discussed. PMID:26385898

    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.

    Over the last decade, the number of homicides in Porto Alegre has increased to the point where external causes are now the main group of causes of death in the 5-34-year age group. Preventing these deaths depends fundamentally on identifying factors related to excess violence in population groups. The overall aim of this study is to analyse the spatial distribution of homicide victims by place of residence in Porto Alegre, the capital of the southernmost Brazilian State of Rio Grande do Sul, in 1996, in order to identify and understand the socio-spatial context. Demographic and socioeconomic indicators based on the 1991 census and 1996 population count were used to build a multivariate classification characterizing the 1851 census tracts. Homicides occurring in 1996 were located using the municipality's Geographic Information System. Four socioeconomic groups were identified, mainly differentiated by housing indicators. Small areas on the urban periphery in which slums (favelas) are concentrated presented higher homicide rates. Homicide rates were lower in the two groups with higher income and educational level. The second step was to classify the census tracts according to the homicide indicator. In this case, areas were differentiated by the number of household inhabitants per room, income, schooling, and median age. We conclude that the multivariate socioeconomic classification presents a limited capacity to identify populations exposed to homicides, suggesting that socioeconomic conditions themselves do not determine violent behaviour. On the other hand, the spatial methods allowed us to identify small areas where deaths are concentrated and whose populations should receive special attention in planning measures to prevent violent deaths.

    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

    Combined homicide-suicides have been classified based on the psychopathology of the perpetrator and the nature of the relationship between perpetrator and victim(s). To further understand the nature of this tragic phenomenon and to test the validity and practicality of a previously suggested classification system, investigators systematically collected data on all combined homicide-suicide events that occurred in Galveston County, Texas over a continuous 18-year period (n = 20). The most common psychopathological finding for perpetrators was high serum alcohol levels that suggested intoxication. Most combined homicide-suicides fell into one of the relational categories and most of these, as predicted, were of the consortial type, possessive subtype. As expected, due to the small sample size, the less common types of combined homicide-suicide were not represented in this sample.

    There are very few recent studies of the incidence and prevalence of head lice in the UK. A population-based questionnaire survey was carried out in a district health authority area. Two hundred and four of 235 primary schools (87%) agreed to participate. A total of 21,556 of 43,889 (49%) questionnaires were returned by parents. Overall 438 children had head lice at the time of the survey, giving a prevalence of 2.03%; 8,059 had had lice at some time in the last year giving an annual incidence of 37.4%.

    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.

    We have reported a high prevalence of breast cancer in light-polluted areas in Korea. However, it is necessary to analyze the spatial effects of light polluted areas on breast cancer because light pollution levels are correlated with region proximity to central urbanized areas in studied cities. In this study, we applied a spatial regression method (an intrinsic conditional autoregressive [iCAR] model) to analyze the relationship between the incidence of breast cancer and artificial light at night (ALAN) levels in 25 regions including central city, urbanized, and rural areas. By Poisson regression analysis, there was a significant correlation between ALAN, alcohol consumption rates, and the incidence of breast cancer. We also found significant spatial effects between ALAN and the incidence of breast cancer, with an increase in the deviance information criterion (DIC) from 374.3 to 348.6 and an increase in R2 from 0.574 to 0.667. Therefore, spatial analysis (an iCAR model) is more appropriate for assessing ALAN effects on breast cancer. To our knowledge, this study is the first to show spatial effects of light pollution on breast cancer, despite the limitations of an ecological study. We suggest that a decrease in ALAN could reduce breast cancer more than expected because of spatial effects.

    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.

  3. Sexual burglaries and sexual homicide: clinical, forensic, and investigative considerations.

    Burglary, the third most common crime after larceny-theft and motor vehicle theft, is rarely the focus of forensic psychiatric study. While most burglaries are motivated simply by material gain, there is a subgroup of burglaries fueled by sexual dynamics. The authors differentiate two types of sexual burglaries: 1) fetish burglaries with overt sexual dynamics; and 2) voyeuristic burglaries, in which the sexual element is often covert and far more subtle. Many forensic practitioners have informally noted the relationship of burglaries to sexual homicide, but this relationship has not otherwise been studied in any detail. In this article, the incidence of (sexual) burglaries by 52 sexual murderers whom the authors evaluated, as well as the incidence in cases reported by others, is reported. Implications of these findings for forensic assessments and profiling of unidentified offenders are discussed.

    To study risks of abuse, violence, and homicide, 181 Abused Children (M age = 12.85 yr., SD = 2.74; 58 girls, 123 boys) were matched with 181 clinic-referred Controls. Data analysis was Shao's bootstrapped logistic regression with area under curve (AUC) and odds ratios (OR). Predictors of abused status were court contacts (OR = 2.04e+22) and poorer executive function (OR = .81; AUC = .99; 95% CI = .97-.99). Groups were tracked forward in records for 9 years (M = 8.78 yr., SD = 1.41). Looking forward, youth (M age = 21.63 yr., SD = 2.07) were classified into Abused Children Later Homicidal (5%, n = 10), Abused Children Later Violent (23%, n = 41), Abused Children Later Delinquent (28%, n = 50), Abused Children Later Nondelinquent (44%, n = 80), and Controls (n = 181). Data were analyzed with two more logistic regressions. Predictors of Abused Children Later Homicidal compared with Controls were number of court contacts (OR = 50,398.78) and poorer executive function (OR = 79.72; AUC = .91; 95% CI = .80-.95). The predictor of Abused Children Later Homicidal contrasted with Abused Children Later Nondelinquent was court contacts (OR = 2,077,089,352; AUC = .87; 95% CI = .65-.95). The common predictor for Abused Children and Abused Children Later Homicidal groups was court contacts.

  5. Comparing death certificate data with FBI crime reporting statistics on U.S. homicides.

    Both the National Center for Health Statistics (NCHS) Mortality System and the Federal Bureau of Investigation (FBI) Uniform Crime Reporting System measure the numbers and characteristics of homicide in the United States. There are important differences, however, in both the substance and the quality of the information that the two systems collect. The NCHS mortality system reported an average of 9 percent more homicides nationally than did the FBI crime reporting system during the 1976-82 period. Variations did occur in the average ratios of the frequencies of homicides reported by the two systems across age, race, and sex subgroups and geographic areas. The major source of the ascertainment difference between the NCHS and the FBI systems is thought to be incomplete voluntary reporting to the FBI by participating law enforcement agencies and lack of reporting by nonparticipating agencies. The proportions of homicides among corresponding demographic categories in the two systems is remarkably similar despite the difference in ascertainment. This congruence of the distributions of reported homicides supports the idea that inferences drawn from analysis of variables in one of these systems will be valid for the population reported on by the other system.

    Background Monitoring the HIV epidemic in a defined population is critical for planning treatment and preventive strategies. This is especially important in sub-Saharan Africa, which harbours the highest burden of the disease. Objective To estimate HIV incidence in adults aged 18-47 years old and to investigate spatial variations of HIV prevalence in Manhiça, a semi-rural area of southern Mozambique. Methods Two cross-sectional community-based surveys were conducted in 2010 and 2012 to determine HIV prevalence. Individual participants were randomly selected from the demographic surveillance system in place in the area and voluntary HIV counselling and testing was offered at the household level. HIV incidence was calculated using prevalence estimates from the two sero-surveys. Each participant’s household was geocoded using a global information system. The Spatial Scan Statistics programme was used to identify areas with disproportionate excess in HIV prevalence. Results A total of 1511 adults were tested. The estimated HIV prevalence in the community was 39.9% in 2010 and 39.7% in 2012. The overall HIV incidence was 3.6 new infections per 100 person-years at risk (PYAR) [95CI 1.56; 7.88], assuming stable epidemic conditions, and tended to be higher in women (4.9/100 PYAR [95CI 1.74; 11.85]) than in men (3.2/PYAR [95CI 1.36; 9.92]). One cluster with significant excess HIV prevalence was identified at the same geographic location in both surveys. This cluster had an HIV prevalence of 79.0% in 2010 and 52.3% in 2012. Conclusions The findings of these first individually-randomised community-HIV sero-surveys conducted in Mozambique reinforce the need to combine HIV incidence estimates and research on micro geographical infection patterns to guide and consolidate effective prevention strategies.

    Background Cali, Colombia, has a high incidence of interpersonal violence deaths. Various alcohol control policies have been implemented to reduce alcohol-related problems. The objective of this study was to determine whether different alcohol control policies were associated with changes in the incidence rate of homicides. Methods Ecologic study conducted during 2004–08 using a time-series design. Policies were implemented with variations in hours of restriction of sales and consumption of alcohol. Most restrictive policies prohibited alcohol between 2 a.m. and 10 a.m. for 446 non-consecutive days. Moderately restrictive policies prohibited alcohol between 3 a.m. and 10 a.m. for 1277 non-consecutive days. Lax policies prohibited alcohol between 4 a.m. and 10 a.m. for 104 non-consecutive days. In conditional autoregressive negative binomial regressions, rates of homicides and unintentional injury deaths (excluding traffic events) were compared between different periods of days when different policies were in effect. Results There was an increased risk of homicides in periods when the moderately restrictive policies were in effect compared with periods when the most restrictive policies were in effect [incidence rate ratio (IRR) 1.15, 90% confidence interval (CI) 1.05–1.26, P = 0.012], and there was an even higher risk of homicides in periods when the lax policies were in effect compared with periods when the most restrictive policies were in effect (IRR 1.42, 90% CI 1.26–1.61, P < 0.001). Less restrictive policies were not associated with increased risk of unintentional injury deaths. Conclusion Extended hours of sales and consumption of alcohol were associated with increased risk of homicides. Strong restrictions on alcohol availability could reduce the incidence of interpersonal violence events in communities where homicides are high. PMID:21450681

  8. Parasite stress promotes homicide and child maltreatment.

    2011-12-12

    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.

    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.

    2017-02-16

    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.

    2013-01-01

    Until recently, there has been little information regarding female offenders who commit homicides that are motivated by psychosis. We investigated gender differences in the characteristics of psychosis and crime variables in psychotically motivated homicide. In the study, conducted at a large U.S. forensic facility, we reviewed the records of women (n = 47) found not guilty by reason of insanity (NGRI) who were hospitalized between January 1991 and August 2005 for a homicide offense. A random sample of 47 men who were committed during the same period for the same offenses was selected for comparison. Religious delusions were found more often in women who killed infants (0-1 year of age) and children between the ages of 2 and 18. Women were more likely to have a diagnosis of an affective problem and borderline personality disorder. The results indicate gender-specific areas to focus on during clinical and forensic assessments of the risk of violence in women with psychosis.

    There are six Areas of Concern, as identified by the International Joint Commission, located in New York State. Three are contiguous in western New York and have similar contaminants (Buffalo River, Niagara River, and 18 Mile Creek). We used the Statewide Planning and Research Cooperative System database, which records diagnoses according to the (italic)International Classification of Disease, Ninth Revision(/italic) codes for all patients admitted to state-regulated hospital facilities, to compare incidence of selected diseases reported in hospitalized patients who reside in ZIP codes that are within 15 miles of any of these sites to those of residents of three different control populations: all residents of the rest of New York State (including New York City), all residents of ZIP codes outside New York City that do not contain any site identified as a federal or state Superfund site, and all residents of ZIP codes outside New York City that contain a federal or state Superfund site that does not have one or more persistent organic pollutants listed as a major contaminant. We found a significant elevation of disorders of the thyroid gland in women, but not in men, of all ages greater than 25 years on all three comparisons, as well as an increased incidence of morbidity from diseases of the female genital tract in women between age 25 to greater than 75 years for all comparison groups. There was also a significant elevation in incidence of endometriosis in women 25-44 years of age. All these elevations were significant at the 99% confidence level. Incidence of diseases of ovaries and testes and female infertility were not different from those in the rest of New York State. Although many factors influence incidence of thyroid and genital diseases, our results are consistent with the hypothesis that exposure to environmental contaminants through residence near polluted sites may be a factor.

    Cancer Registries are an essential part of any rational programme of cancer control, for assessing the impact of cancer in the community, for health care planning and monitoring screening programmes, according to local enviromental problems. The Brescia Cancer Registry started in 1994 producing prevalence, incidence and mortality data using only manual procedures of colletting and processing data from clinical and pathological sources in Brescia in 1993--1995. Data quality indicators such as the percentages of istologically or cytologically verified cases and that of cases registered on the basis of Death Certificate Only (DCO) are similar to those from the other Northern Italian Registries. Incidence rates for all causes and for various common sites are higher in Brescia than in other areas covered by Cancer Registries in North of Italy.

    The aim of the present study was to investigate the possible association between occurrence of soft tissue sarcomas (STS) and residence in an Italian area affected by illegal practices of dumping and setting fire to both hazardous and solid urban wastes. Standardized incidence ratios (SIRs) were computed separately for STS and some specific STS subtypes. The analysis was performed for the total population and for specific age groups, namely, children, adolescents, and adults. In adults, no significant increase in STS was found other than for gastrointestinal stromal tumors in males. A nonsignificant increase in incidence of STS was observed for male children and female adolescents. The results of the present study do not allow conclusions for a causal association. In the absence of previous epidemiological studies on this issue, further investigations are needed.

    With the exception of Guyana and Trinidad, suicide rates in the Caribbean are relatively low compared with those in other countries. Homicide rates, however, have increased over the past 15 years, especially in Jamaica and Trinidad. The link between suicide, homicide, and homicide followed by suicide (H-S) is not well established. A newspaper review of H-S events in a selection of Caribbean territories revealed a surprising number of these events. Characteristics of perpetrators were similar to those documented in the literature. The authors agree with Roma et al. that national tracking systems for H-S are needed. Empirical research on this topic in the Caribbean is also desperately needed.

    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.

    A sample of incarcerated sexual homicide perpetrators (n = 18) were compared to a sample of non-sexually offending but violent male psychopaths (n = 23) on select Rorschach variables using the Comprehensive System (Exner, 1991). Results suggest that sexual homicide perpetrators are similar to psychopaths in their attachment abnormality, characterological anger, pathological narcissism, moderate and pervasive formal thought disorder, and borderline reality testing. They are distinguished, however, by a more frequent affectional hunger, a tendency to engage in more dysphoric rumination, and abnormal elevations of nonvolitional ideation (obsessional thoughts) due to unmet instinctual need states. They also show a greater interest in others as whole, real, and meaningful objects. Five psychodynamic factors, supported by the empirical findings, are proposed to partially explain the intrapsychic mechanisms involved in an act of sexual homicide.

    Carbon emissions released from forest fires have been identified as an environmental issue in the context of global warming. This study provides data on spatial and temporal patterns of fire incidences, burnt area and carbon emissions covering natural vegetation types (forest, scrub and grassland) and Protected Areas of India. The total area affected by fire in the forest, scrub and grasslands have been estimated as 48765.45, 6540.97 and 1821.33 km 2, respectively, in 2014 using Resourcesat-2 AWiFS data. The total CO 2 emissions from fires of these vegetation types in India were estimated to be 98.11 Tg during 2014. The highest emissions were caused by dry deciduous forests, followed by moist deciduous forests. The fire season typically occurs in February, March, April and May in different parts of India. Monthly CO 2 emissions from fires for different vegetation types have been calculated for February, March, April and May and estimated as 2.26, 33.53, 32.15 and 30.17 Tg, respectively. Protected Areas represent 11.46% of the total natural vegetation cover of India. Analysis of fire occurrences over a 10-year period with two types of sensor data, i.e., AWiFS and MODIS, have found fires in 281 (out of 614) Protected Areas of India. About 16.78 Tg of CO 2 emissions were estimated in Protected Areas in 2014. The natural vegetation types of Protected Areas have contributed for burnt area of 17.3% and CO 2 emissions of 17.1% as compared to total natural vegetation burnt area and emissions in India in 2014. 9.4% of the total vegetation in the Protected Areas was burnt in 2014. Our results suggest that Protected Areas have to be considered for strict fire management as an effective strategy for mitigating climate change and biodiversity conservation.

    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.

    The aim of the study was to evaluate the incidence rate (IR), trend and histotype of the differentiated thyroid cancer in the selected areas with varying iodine deficiency. The study was carried out in three areas: Krakow, (Carpathian endemic goiter area with 1.99 million mixed rural and urban population), Gliwice (Upper Silesia--moderate iodine deficiency area mostly industrial with 4.89 million inhabitants) and Olsztyn (slight iodine deficiency area, mainly rural with 0.77 million inhabitants). Between 1990 and 2001, in the study area 2691 newly diagnosed cases of malignant neoplasms of the thyroid gland were registered. In over 80% of patients it was differentiated thyroid cancer: mainly in women over 40 years, with F/M ratio 5.8. The highest percentage of papillary cancer 72.9% was observed in Olsztyn and lowest--50.0%--in Krakow and Nowy Sacz districts. In this period of time incidence rate of differentiated thyroid cancer in women increased in Kraków, Gliwice, and Olsztyn from 1.51 to 9.34 in 1998 1.27 to 5.74 in 1999 and from 2.52 to 11.35 in 2001 respectively. In the youngest (0-20 years) age group no significant increase of IR was observed. Between 1998 and 2001 the dynamics of increase of the thyroid cancer incidence markedly diminished. In conclusion it was hypothesised that an increase in IR of differentiated thyroid cancer in the study area was caused mainly by the suspension of iodine prophylaxis in 1980 and was diminished by the introduction of an obligatory model of iodine prophylaxis in 1996/1997. It was modified in terms of histotype and dynamics of increase by exposure to ionizing radiation. A very specific group at risk on the population level were women aged 20-40 years in the reproductive age exposed to iodine deficiency after suspension of iodine prophylaxis in 1980 and to radiation after the Chernobyl accident in 1986.

    The incidence of tuberculosis (TB) and its risk factors in China remains unclear. This study examined TB incidence and relative risk factors in rural areas of China. Participants (n = 177,529) were recruited in Xiangtan County (in the central area of China) and in Danyang County (in the eastern area of China) in 2009 and a followed-up study was conducted for one year. The incidence density of pulmonary TB and smear-positive TB were 91.6 (95% CI: 78.7, 106.0) per 100,000 person-year and 36.7 (95% CI: 33.1, 52.4) per 100,000 person-year respectively in Xiangtan, and 47.3 (95% CI: 38.2, 57.5) per 100,000 person-year and 22.7 (95% CI: 16.5, 30.8) per 100,000 person-year in Danyang. The medical history of TB was associated with TB, with the relative risk (RR) of 7.00 (95% CI: 2.76, 17.18) in Xiangtan and that of 31.08 (95% CI: 13.22, 73.10) in Danyang. The association between TB and per capita living space over median was found in Xiangtan, with the RR of 1.86 (95% CI: 1.15, 3.01). No association was found between TB and the insurance status, the contact history with TB, the history of diabetes, smoking, or per capita annual income. The host genetic susceptibility, and social factors such as education and income could be considered in future studies.

    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

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

    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.

    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.

    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.

    Isolated areas, such as the 2 × 7 km peninsula of Linga Linga in Mozambique, are the places where malaria might be most easily eliminated. Currently available control strategies include long-lasting insecticidal bednets impregnated with pyrethroid insecticides (LLINs), rapid diagnostic tests (RDTs) for diagnosis and artemisinin based combination therapy (ACT) for treatment and these were applied on the peninsula. In 2007, following a census of the population and mapping of 500 households, five annual all-age prevalence surveys were conducted. Information on LLIN use, house construction, and animal ownership was obtained. A spatially structured generalized additive model indicated that malaria risk was greatest towards the northern end of the peninsula and that people living in houses with grass or thatch roofs had a greater risk of malaria than those living in houses with corrugated iron roofs. Incidence peaked nine weeks after rainfall (r2 = 0.34, p = 0.0002). From 2009 incidence was measured at a centrally based project clinic. The proportion of under nine-year-old resident attendees diagnosed with malaria decreased significantly from 48% in 2009, to 35% in 2010 and 25% in 2011. At the same time, there was a shift in the peak age of cases from 1–4 year olds to 5–9 year olds. Nevertheless, in order to further reduce malaria transmission in an area such as Linga Linga, additional vector control measures need to be considered. PMID:26587341

    To examine the incidence, characteristics, therapeutic approach and survival of diagnosed lung cancer (LC) in the Santiago de Compostela Health Area. A retrospective study was carried out on LC for a period of 3 years. Of the 481 cases collected, 92.7% were male. The median age was 66.93 years. The crude incidence for men and women was 80.71 and 5.84 per 100,000 inhabitants respectively. Among the non-small cell lung cancers (NSCLC), 68.1% were diagnosed in stage IIIB or IV. The cancer had already spread in 62.2% of the small cell lung cancer (SCLC). Chemotherapy was used in 51.6% of patients. The survival probability from the first to the fifth year was 47.7%, 24.3%, 12.9%, 10% and 8.9% respectively. The median survival at 5 years was 12.12 months for NSCLC, rising to 29.8 months in stage I, and 8.85 months in SCLC. In our Health Area LC occurs more often in men, in whom the prevalence of smoking is very high. The most common histology type was squamous cell carcinoma. In the majority of cases, the diagnosis is made in the advanced stages, which accounts for the low percentage of surgical treatments and the short survival.

    Defendants commonly claim amnesia for their criminal actions especially in cases involving extreme violence. While some claims are malingered or result from physiological factors, other cases may represent genuine partial or complete amnesia resulting from the psychological distress and/or extreme emotion associated with the perpetration of the crime. Fifty Canadian homicide offenders described their memories of their homicide, a non-homicide violent offense, and their most positive adulthood life experience. Self-reported and objective measures of memories for these events revealed that homicides were recalled with the greatest level of detail and sensory information. Although dissociative tendencies were associated with a self-reported memory loss, objective measures of memory quality did not reflect this perceived impairment, suggesting a failure of meta-memory. Recollections of positive life events were superior to those of non-homicidal violence, possibly due to greater impact and meaning attached to such experiences. Findings suggest that memory for homicide typically is enhanced by the powerful emotion associated with its perpetration.

  18. Analytical computation of the off-axis effective area of grazing incidence X-ray mirrors

    2009-10-01

    Aims: Focusing mirrors for X-ray telescopes in grazing incidence, introduced in the 70s, are characterized in terms of their performance by their imaging quality and effective area, which in turn determines their sensitivity. Even though the on-axis effective area is assumed in general to characterize the collecting power of an X-ray optic, the telescope capability of imaging extended X-ray sources is also determined by the variation in its effective area with the off-axis angle. The effective area, in general, decreases as the X-ray source moves off-axis, causing a loss of sensitivity in the peripheral regions of the telescope's field of view. Methods: The complex task of designing optics for future X-ray telescopes entails detailed computations of both imaging quality and effective area on- and off-axis. Because of their apparent complexity, both aspects have been, so far, treated by using ray-tracing routines aimed at simulating the interaction of X-ray photons with the reflecting surfaces of a given focusing system. Although this approach has been widely exploited and proven to be effective, it would also be attractive to regard the same problem from an analytical viewpoint, to assess an optical design of an X-ray optical module with a simpler calculation than a ray-tracing routine. This would also improve the efficiency of optimization tasks when designing the X-ray optical modules. In this paper, we thereby focused on developing analytical solutions to compute the off-axis effective area of double-reflection X-ray mirrors. Results: We have developed useful analytical formulae for the off-axis effective area of a double-reflection mirror in the double cone approximation, requiring only an integration and the standard routines to calculate the X-ray coating reflectivity for a given incidence angle. The computation is easily applicable also to Wolter-I mirrors (such as those of NeXT, NuSTAR, HEXIT-SAT, IXO) and the approximation improves as the f-number of the

    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.

    Background The risk of Plasmodium falciparum infection is variable over space and time and this variability is related to environmental variability. Environmental factors affect the biological cycle of both vector and parasite. Despite this strong relationship, environmental effects have rarely been included in malaria transmission models. Remote sensing data on environment were incorporated into a temporal model of the transmission, to forecast the evolution of malaria epidemiology, in a locality of Sudanese savannah area. Methods A dynamic cohort was constituted in June 1996 and followed up until June 2001 in the locality of Bancoumana, Mali. The 15-day composite vegetation index (NDVI), issued from satellite imagery series (NOAA) from July 1981 to December 2006, was used as remote sensing data. The statistical relationship between NDVI and incidence of P. falciparum infection was assessed by ARIMA analysis. ROC analysis provided an NDVI value for the prediction of an increase in incidence of parasitaemia. Malaria transmission was modelled using an SIRS-type model, adapted to Bancoumana's data. Environmental factors influenced vector mortality and aggressiveness, as well as length of the gonotrophic cycle. NDVI observations from 1981 to 2001 were used for the simulation of the extrinsic variable of a hidden Markov chain model. Observations from 2002 to 2006 served as external validation. Results The seasonal pattern of P. falciparum incidence was significantly explained by NDVI, with a delay of 15 days (p = 0.001). An NDVI threshold of 0.361 (p = 0.007) provided a Diagnostic Odd Ratio (DOR) of 2.64 (CI95% [1.26;5.52]). The deterministic transmission model, with stochastic environmental factor, predicted an endemo-epidemic pattern of malaria infection. The incidences of parasitaemia were adequately modelled, using the observed NDVI as well as the NDVI simulations. Transmission pattern have been modelled and observed values were adequately predicted. The error

    Objective: To examine whether measures of neighbourhood economic deprivation, social disorganisation, and acculturation explain homicide mortality differentials between Mexican Americans, non-Hispanic black Americans, and non-Hispanic white Americans, net of individual factors. Design: Prospective study, National Health Interview Survey (1986–1994) linked to subsequent mortality in the National Death Index (1986–1997). Setting: United States of America. Participants: A nationally representative sample of non-institutionalised Mexican Americans, non-Hispanic black Amricans, and non-Hispanic white Americans, aged 18–50 at the point of interview. Analysis: Cox proportional hazard models estimate the risk of death associated with various neighbourhood and individual factors. Main results: Both individual and neighbourhood risk factors partially account for race/ethnic disparities in homicide. Homicide mortality risks are between 20% and 50% higher for residents of areas that have economic inequality of 0.50 or greater based on the coefficient of variation, or where 4% or more of the residents are Mexican American, 10% or more of the residents are non-Hispanic black, or 20% or more of the households are headed by single parents (p⩽.05). But residents of areas where 10% or more of their neighbours are foreign born have 35% lower mortality risks than people living in areas with fewer foreign born people (p⩽0.05). These differences persist even after controlling for individual level risk factors. Conclusions: The findings support economic deprivation, social disorganisation, and acculturation theories, and suggest that both neighbourhood and individual risk factors affect race/ethnic differences in homicide mortality. Public health policies must focus on both individual and neighbourhood factors to reduce homicide risks in vulnerable populations. PMID:14966236

    Aims: To evaluate the incidence risk of lymphohaematopoietic cancers for the 1986–94 period in Cornigliano, a district of Genoa (Italy), where a coke oven is located a few hundred metres from the residential area. Methods: The whole of Genoa and one of its 25 districts (Rivarolo) were selected as controls. The trend of risk around the coke oven was evaluated via Stone's method, while the geographic pattern of such risks across the Cornigliano district was evaluated by computing full Bayes estimates of standardised incidence ratio (FBE-SIR). Results: In males, elevated relative risks (RR) were observed for all lymphohaematopoietic cancers (RR 1.7 v Rivarolo and 1.6 v Genoa), for NHL (RR 2.4 v Rivarolo and 1.7 v Genoa), and for leukaemia (RR 2.4 v Rivarolo and 1.9 v Genoa). In females, statistically non-significant RR were observed. In males no excess of risk was found close to the coke oven. In females, a rising risk for NHL was observed approaching the plant, although statistical significance was not reached, while the risk for leukaemia was not evaluable due to the small number of cases. Analysis of the geographic pattern of risk suggested the presence of a cluster of NHL in both sexes in the eastern part of the district, where a foundry had been operational until the early 1980s. A cluster of leukaemia cases was observed in males in a northern part of the area, where no major sources of benzene seemed to be present. Conclusions: The estimated risks seem to be slightly or not at all related to the distance from the coke oven. The statistically significant higher risks observed in males for NHL and leukaemia, and the clusters of leukaemia in males and of NHL in both sexes deserve further investigations in order to trace the exposures associated with such risks.

    2013-01-01

    Background Substance misuse is a well-recognized co-morbidity to psychosis and has been linked to poor prognostic outcomes in patients. Researchers have yet to investigate the difference in rates and characteristics between first-episode Substance Induced Psychosis (SIP) and primary psychosis. We aimed at comparing patients with SIP to primary psychosis patients with or without substance misuse at baseline. Methods Thirty SIP patients, 45 primary psychosis patients with substance misuse (PS) and 66 primary psychosis patients without substance misuse (PNS) in a well-defined Norwegian catchment area were included from 2007–2011. Assessments included symptom levels (PANSS), diagnostic interviews (SCID), premorbid function scale (PAS) and global functioning (GAF f/s). Results Treated incidence for SIP was found to be 6.5/100 000 persons per year, 9.7/100 000 persons per year for PS and 24.1/100 000 persons per year for PNS (15-65 yrs). Patients who had substance misuse (PS and SIP) were more likely to be male. Duration of Untreated Psychosis (DUP) was significantly shorter in the SIP group (5.0 wks., p = 0.003) and these had more positive symptoms on the PANSS (p = 0.049). SIP patients also did poorer on early youth academic levels on the PAS. Conclusions Yearly treated incidence of SIP is 6.5/100 000 persons per year in a Norwegian catchment area. SIP patients have short DUPs, are more likely to be male, have more positive symptoms at baseline and poorer premorbid academic scores in early adolescence. Follow-up will evaluate stability of diagnosis and characteristics. PMID:24279887

    Current rates of intimate partner homicide of females are approximately 4 to 5 times the rate for male victims, although the rates for both have decreased during the past 25 years. The major risk factor for intimate partner homicide, no matter if a female or male partner is killed, is prior domestic violence. This review presents and critiques the evidence supporting the other major risk factors for intimate partner homicide in general, and for intimate partner homicide of women (femicide) in particular, namely guns, estrangement, stepchild in the home, forced sex, threats to kill, and nonfatal strangulation (choking). The demographic risk factors are also examined and the related phenomena of pregnancy-related homicide, attempted femicide, and intimate partner homicide-suicide.

    Homicides of dependent elderly and nonelderly adults by their caregivers violate trust and have long-term consequences for families. A better understanding of the characteristics of homicide by caregivers may provide insights that can inform prevention efforts. Data collected in the National Violent Death Reporting System (NVDRS) between 2003 and 2007 are used to characterize victims, perpetrators, and caregiver roles, and circumstances that precipitated homicides by a caregiver. A total 68 incidents are categorized into either homicide by neglect ( n = 17), intentional injury of the victim only (n = 21), or homicide followed by suicide of the perpetrator (n = 30). Demographics, mechanism of injury, location of injury, and victim-suspect relationship variables are supplemented by narrative accounts of incidents. In general, findings show that adult homicide victims of a caregiver were widowed (42.6%), non-Hispanic (97.1%), White (88.2%), women (63.2%) killed in their homes (92.6%) with a firearm (35.3%) or by intentional neglect (25.0%) by a husband (30.9%) or a son (22.1%). Nearly half were aged 80 years and older (48.5%), 42.6% were aged 50 to 79 years, and 0.9% were aged 20 to 49 years. Many homicide by caregiver incidents are precipitated by physical illness of the victim or caregiver, opportunity for perpetrator financial gain, mental illness of the caregiver, substance use by the caregiver, or an impending crisis in the life of the caregiver not related to illness. Understanding the vulnerabilities of victims, the characteristics of suspects, and the multiple types of motivations is key to developing effective prevention efforts.

    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.

    This study focuses on the relationship between women's risk of homicide as measured by the Danger Assessment and 13 protective actions. Participants (N = 432) experienced an incident of police involved intimate partner violence (IPV) and subsequently completed a structured telephone interview. Most women in this sample experienced severe violence and were classified as being at high risk for homicide. Participants engaged in an average of 3.81 (SD = 2.73) protective actions. With the exception of the use of formal domestic violence services, women in the high-risk category were significantly more likely than women in the lower risk category to have used each of the protective actions examined. Implications for research and practice are discussed.

    Cholera is an important public health problem in Bangladesh. Interventions to prevent cholera depend on their cost-effectiveness which in turn depends on cholera incidence. Hospital-based diarrhoeal disease surveillance has been ongoing in six Bangladeshi hospitals where a systematic proportion of patients admitted with diarrhoea were enrolled and tested for Vibrio cholerae. However, incidence calculation using only hospital data underestimates the real disease burden because many ill persons seek treatment elsewhere. We conducted a healthcare utilization survey in the catchment areas of surveillance hospitals to estimate the proportion of severe diarrhoeal cases that were admitted to surveillance hospitals and estimated the population-based incidence of severe diarrhoea due to V. cholerae by combining both hospital surveillance and catchment area survey data. The estimated incidence of severe diarrhoea due to cholera ranged from 0.3 to 4.9/1000 population in the catchment area of surveillance hospitals. In children aged <5 years, incidence ranged from 1.0 to 11.0/1000 children. Diarrhoeal deaths were most common in the Chhatak Hospital's catchment area (18.5/100 000 population). This study provides a credible estimate of the incidence of severe diarrhoea due to cholera in Bangladesh, which can be used to assess the cost-effectiveness of cholera prevention activities.

    SUMMARY Cholera is an important public health problem in Bangladesh. Interventions to prevent cholera depend on their cost-effectiveness which in turn depends on cholera incidence. Hospital-based diarrhoeal disease surveillance has been ongoing in six Bangladeshi hospitals where a systematic proportion of patients admitted with diarrhoea were enrolled and tested for Vibrio cholerae. However, incidence calculation using only hospital data underestimates the real disease burden because many ill persons seek treatment elsewhere. We conducted a healthcare utilization survey in the catchment areas of surveillance hospitals to estimate the proportion of severe diarrhoeal cases that were admitted to surveillance hospitals and estimated the population-based incidence of severe diarrhoea due to V. cholerae by combining both hospital surveillance and catchment area survey data. The estimated incidence of severe diarrhoea due to cholera ranged from 0·3 to 4·9/1000 population in the catchment area of surveillance hospitals. In children aged <5 years, incidence ranged from 1·0 to 11·-0/1000 children. Diarrhoeal deaths were most common in the Chhatak Hospital’s catchment area (18·5/100 000 population). This study provides a credible estimate of the incidence of severe diarrhoea due to cholera in Bangladesh, which can be used to assess the cost-effectiveness of cholera prevention activities.

  12. Thyroid cancer incidence among people living in areas contaminated by radiation from the Chernobyl accident.

    PubMed

    Ron, Elaine

    2007-11-01

    As a result of the Chernobyl nuclear power plant accident, massive amounts of radioactive materials were released into the environment and large numbers of individuals living in Belarus, Russia, and Ukraine were exposed to radioactive iodines, primarily 131I. Iodine-131 concentrated in the thyroid gland of residents of the contaminated areas, with children and adolescents being particularly affected. In the decade after the accident, a substantial increase in thyroid cancer incidence was observed among exposed children in the three affected countries, and compelling evidence of an association between pediatric thyroid cancer incidence and radiation exposure to the thyroid gland accumulated. The data currently available suggest that both the magnitude and patterns of thyroid cancer risk are generally consistent with those reported following external exposure. Based on data from case-control studies, iodine deficiency appeared to enhance the risk of developing thyroid cancer following exposure from Chernobyl. Results from a recent large cohort study, however, did not support these findings. Data on adult exposure are limited and not entirely consistent. Similarly, information on thyroid cancer risks associated with in utero exposure is insufficient to draw conclusions. The lack of information on these two population groups indicates an important gap that needs to be filled. Twenty years after the accident, excess thyroid cancers are still occurring among persons exposed as children or adolescents, and, if external radiation can be used as a guide, we can expect an excess of radiation-associated thyroid cancers for several more decades. Since considerable uncertainties about the long-term health effects from Chernobyl remain, continued follow-up of the exposed populations should provide valuable information.

    An increase in waterborne illnesses related to floodings has been reported all over the world, especially in developing countries. In Dhaka City, floodings occur almost every year due to severe rainfall compounded by inadequate sewerage systems. Waterborne illnesses spread easily in an unhygienic environment. This study develops a method to estimate the incidences of diarrhoea associated with floodings using a flooding analysis. We performed a flooding analysis using a numerical flooding simulation model and investigated the relationship between floodwater depth and diarrhoea incidence. The incidence of diarrhoea was assessed through a mortality and morbidity survey conducted in 10 low-income communities in flood-prone areas of Dhaka City. The results revealed that there is a positive correlation between floodwater depth and indices of diarrhoea incidence. This indicates that a flooding analysis method can be used to estimate diarrhoea incidence.

    In a retrospective investigation of the court reports about sexual homicide perpetrators chromosome analysis had been carried out in 13 of 166 (7.8%) men. Three men (1.8%) with XYY chromosome abnormality were found. This rate is much higher than that found in unselected samples of prisoners (0.7-0.9%) or in the general population (0.01%). The three men had shown prepubescent abnormalities, school problems, and had suffered from physical abuse. The chromosome analysis in all cases had been carried out in connection with the forensic psychiatric court report due to the sexual homicide. However, two men had earlier psychiatric referrals. All were diagnosed as sexual sadistic, showed a psychopathic syndrome or psychopathy according to the Psychopathy Checklist-Revised [Hare RD, 1991, The Hare Psychopathy Checklist-Revised, Toronto, Ontario, Canada: Multi-Health Systems]. Two were multiple murderers. Especially forensic psychiatrists should be vigilant of the possibility of XYY chromosome abnormalities in sexual offenders.

    Juvenile homicide is a social problem that has remained a central focus within juvenile justice research in recent years. The term juvenile murderer describes a legal category, but it is purported to have significant scientific meaning. Research has attempted to conceptualize adolescent murderers as a clinical category that can be reliably distinguished from their nonhomicidal counterparts. This study examined 33 adolescents adjudicated delinquent or awaiting trial for murder and 38 adolescents who committed violent, nonhomicidal offenses to determine whether the two groups differed significantly on family history, early development, delinquency history, mental health, and weapon possession variables. The nonhomicide group proved more problematic on many of these measures. Two key factors did distinguish the homicide group: These adolescents endorsed the greater availability of guns and substance abuse at the time of their commitment offenses. The significance of this finding is discussed, and the implications for risk management and policy are reviewed.

    Objective. This study examined institutional anomie theory in the context of transitional Russia. Methods. We employed an index of negative socioeconomic change and measures of family, education, and polity to test the hypothesis that institutional strength conditions the effects of poverty and socioeconomic change on homicide rates. Results. As expected, the results of models estimated using negative binomial regression show direct positive effects of poverty and socioeconomic change and direct negative effects of family strength and polity on regional homicide rates. There was no support, however, for the hypothesis that stronger social institutions reduce the effects of poverty and socioeconomic change on violence. Conclusions. We interpret these results in the Russia-specific setting, concluding that Russia is a rich laboratory for examining the effects of social change on crime and that empirical research in other nations is important when assessing the generalizability of theories developed to explain crime and violence in the United States.

    This retrospective study of medical examiner records from three counties reported on 252 persons who killed 302 victims before killing themselves and reviews the Tarasoff ruling that set the standard for duty to warn and/or protect third parties whose lives are threatened by a patient. The three sites varied significantly for the perpetrator in terms of race, employment, cause of death, and motive. Female offenders killed more children under the age of 10 and adolescents than did male offenders. Evidence of premeditation included suicide notes and weapon brought to the crime scene, while strangulation indicated a spontaneous domestic homicide. Implications for practice are discussed including the importance of evaluating violent thoughts, fantasies, and behaviors in acute emergency settings and recommendations include second opinion consultation for Tarasoff-type cases and psychological autopsy review for completed homicide-suicide cases.

    Even though forensic evidence is collected at virtually every homicide scene, only a few studies have examined its role in investigation and prosecution. This article adds to the literature by providing the results of a study of 294 homicide cases (315 victims) occurring in Cleveland, Ohio, between 2008 and 2011. Through a logistic regression on open versus closed cases, the collection of knives, administration of gunshot residue (GSR) kits, and clothing at the scene were positively and significantly related to case closures, while collection of ballistics evidence and DNA evidence were statistically significant in the opposite direction. With regard to analysis, the clearance rate for cases with probative results (i.e., matches or exclusions) was 63.1% compared to a closure rate of 56.3% for cases without probative results. However, only 23 cases had probative results prior to arrest compared to 128 cases with probative results after arrest.

    The objective of this study was to examine the temporal trends of the association between area-level poverty status and end-stage renal disease (ESRD) incidence. We hypothesized that the association between area-level poverty status and ESRD incidence has increased significantly over time. Patient data from the United States Renal Data System were linked with data from the 2000 and 2010 US census. Area-level poverty was defined as living in a zip code-defined area with ≥20% of households living below the federal poverty line. Negative binomial regression models were created to examine the association between area-level poverty status and ESRD incidence by time period in the US adult population while simultaneously adjusting for the distribution of age, sex, and race/ethnicity within a zip code. Time was categorized as January 1, 1995 through December 31, 2004 (Period 1) and January 1, 2005 through December 31, 2010 (Period 2). The percentage of adults initiating dialysis with area-level poverty increased from 27.4% during Period 1 to 34.0% in Period 2. After accounting for the distribution of age, sex, and race/ethnicity within a zip code, area-level poverty status was associated with a 1.24 (95% confidence interval [CI] 1.22, 1.25)-fold higher ESRD incidence. However, this association differed by time period with 1.04-fold (95% CI 1.02, 1.05) higher ESRD incidence associated with poverty status for Period 2 compared with the association between ESRD and poverty status in Period 1. Area-level poverty and its association with ESRD incidence is not static over time.

    The Mekong Delta is highly vulnerable to climate change and a dengue endemic area in Vietnam. This study aims to examine the association between climate factors and dengue incidence and to identify the best climate prediction model for dengue incidence in Can Tho city, the Mekong Delta area in Vietnam. We used three different regression models comprising: standard multiple regression model (SMR), seasonal autoregressive integrated moving average model (SARIMA), and Poisson distributed lag model (PDLM) to examine the association between climate factors and dengue incidence over the period 2003-2010. We validated the models by forecasting dengue cases for the period of January-December, 2011 using the mean absolute percentage error (MAPE). Receiver operating characteristics curves were used to analyze the sensitivity of the forecast of a dengue outbreak. The results indicate that temperature and relative humidity are significantly associated with changes in dengue incidence consistently across the model methods used, but not cumulative rainfall. The Poisson distributed lag model (PDLM) performs the best prediction of dengue incidence for a 6, 9, and 12-month period and diagnosis of an outbreak however the SARIMA model performs a better prediction of dengue incidence for a 3-month period. The simple or standard multiple regression performed highly imprecise prediction of dengue incidence. We recommend a follow-up study to validate the model on a larger scale in the Mekong Delta region and to analyze the possibility of incorporating a climate-based dengue early warning method into the national dengue surveillance system.

    Testing for latent tuberculosis infection (LTBI) in HIV-infected persons in low tuberculosis (TB) incidence areas is often recommended. Using contemporary, clinical data, we report the yield and cost-effectiveness of testing all HIV attendees, two current UK strategies and no LTBI testing. Economic modelling was performed utilising 10-year follow up data from a large HIV clinical cohort. Outcomes were numbers of cases of active TB and incremental cost per quality-adjusted life year (QALY) gained. Between 2000 and 2010, 256 people were treated for TB/HIV co-infection. 72 (28%) occurred ≥3 months after HIV diagnosis and may have been prevented by LTBI testing. Between 2000 and 2005, the incremental cost per QALY gained for the British HIV Association (BHIVA) and UK National Institute of Care Excellence (NICE) strategies, and testing all clinic attendees was €6270, €6998 and €33,473, respectively. These rose to €9332, €32,564 and €74,067, respectively, between 2005 and 2010. Probabilistic sensitivity analysis suggested that at a threshold of €24,000 per additional QALY, the most cost-effective strategies would be NICE or testing all in 2000-2005 and BHIVA during 2005-2010. Both UK testing regimens missed cases but are cost-effective compared with no testing. Using recent data, they all became more expensive, suggesting that alternative or more targeted TB testing strategies must be considered.

    In the South Bohemian Region which is an area of enzootic incidence of nutritional muscle dystrophy selenium content in the fur of dairy cows and young cattle was determined. In the breeds in which the "white muscle disease" appeared in the past years in young cattle, lambs and calves the lowest mean selenium values in the fur dry matter found were: 0.18 +/- 0.07, 0.19 +/- 0.06, and 0.21 +/- 0.08 ppm, with repeated findings of mere 0.09 ppm Se. 60 to 100 per cent samples from these farms showed selenium values below the 0.25 ppm level. The fur of heifers which recovered from nutritional muscle dystrophy and were treated 10 days prior to sampling with a selenium preparation in injection form (Selevit inf. SPOFA) contained 0.29 ppm selenium (+/- 0.11). In other breeds 0.30 +/- 0.07 to 3.33 +/- 0.16 ppm selenium was found in the fur of cows and young cattle. The initial field essay of selenium content in cattle fur indicated a relation of low selenium values to the frequency of clinical forms of nutritional muscle dystrophy in domestic ruminants.

    The abstract of this paper was presented at the 14th Meeting of the International Association of Forensic Sciences, Tokyo in 1996. We report a bizarre criminal case of suspected serial homicide by injection of a muscle relaxant (succinylcholine). Five victims were found buried in a rural area. In two victims showing moderate decomposition (about three months after death), intense pulmonary oedema with pleural effusion was observed. Evidence of a puncture site was found in one of the victims. Succinylcholine could not be detected in the victims, but was identified in a syringe found near the corpses. The 40-mg ampule dose of succinylcholine administered intramuscularly to the victims, possibly causing prolonged apnea, was considered to be at least around the minimum lethal dose, although the combined effect of the sedation with hypnotics also used was not negligible.

    Covictims of homicide are the loved ones of people killed by homicide. As secondary victims, they experience trauma from the crime yet are not the focus of criminal justice system (CJS) processes. The current descriptive-exploratory study seeks to better understand this often hidden population by exploring the relationship between CJS case status, trauma symptoms, life satisfaction, and coping with a group of 137 covictims from the Mid-South region of the United States. Findings indicate that case closure does not resolve trauma symptoms, although symptoms do lessen. In addition, a broad range of helping services and coping strategies are used after the homicide. Some are associated with CJS case status, trauma symptoms, and life satisfaction whereas others are not. These findings highlight important areas for future research.

    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.

    Urban heat islands are characterized by high land surface temperature, low humidity, and poor vegetation, and considered to favor the transmission of the mosquito-borne dengue fever that is transmitted by the Aedes aegypti mosquito. We analyzed the recorded dengue incidence in Sao Paulo city, Brazil, in 2010-2011, in terms of multiple environmental and socioeconomic variables. Geographical information systems, thermal remote sensing images, and census data were used to classify city areas according to land surface temperature, vegetation cover, population density, socioeconomic status, and housing standards. Of the 7415 dengue cases, a majority (93.1%) mapped to areas with land surface temperature >28°C. The dengue incidence rate (cases per 100,000 inhabitants) was low (3.2 cases) in high vegetation cover areas, but high (72.3 cases) in low vegetation cover areas where the land surface temperature was 29±2°C. Interestingly, a multiple cluster analysis phenogram showed more dengue cases clustered in areas of land surface temperature >32°C, than in areas characterized as low socioeconomic zones, high population density areas, or slum-like areas. In laboratory experiments, A. aegypti mosquito larval development, blood feeding, and oviposition associated positively with temperatures of 28-32°C, indicating these temperatures to be favorable for dengue transmission. Thus, among all the variables studied, dengue incidence was most affected by the temperature.

    The increased thyroid cancer incidence in volcanic areas suggests an environmental effect of volcanic-originated carcinogens. To address this problem, we evaluated environmental pollution and biocontamination in a volcanic area of Sicily with increased thyroid cancer incidence. Thyroid cancer epidemiology was obtained from the Sicilian Regional Registry for Thyroid Cancer. Twenty-seven trace elements were measured by quadrupole mass spectrometry in the drinking water and lichens (to characterize environmental pollution) and in the urine of residents (to identify biocontamination) in the Mt. Etna volcanic area and in adjacent control areas. Thyroid cancer incidence was 18.5 and 9.6/10(5) inhabitants in the volcanic and the control areas, respectively. The increase was exclusively due to the papillary histotype. Compared with control areas, in the volcanic area many trace elements were increased in both drinking water and lichens, indicating both water and atmospheric pollution. Differences were greater for water. Additionally, in the urine of the residents of the volcanic area, the average levels of many trace elements were significantly increased, with values higher two-fold or more than in residents of the control area: cadmium (×2.1), mercury (×2.6), manganese (×3.0), palladium (×9.0), thallium (×2.0), uranium (×2.0), vanadium (×8.0), and tungsten (×2.4). Urine concentrations were significantly correlated with values in water but not in lichens. Our findings reveal a complex non-anthropogenic biocontamination with many trace elements in residents of an active volcanic area where thyroid cancer incidence is increased. The possible carcinogenic effect of these chemicals on the thyroid and other tissues cannot be excluded and should be investigated.

    The use of Japanese swords for homicidal attempts is rare. A Japanese samurai sword is a sharp and cutting object. When faced with the use of this weapon, one must distinguish between stabs and incised wounds. Incised wounds can rarely lead to death, but because of the size of the weapon, stabs usually cause much more serious injuries. Stabs also imply a penetrating movement, whereas incised wounds can be the consequence of protective circular blows. Therefore, it is important to distinguish clinically between these two kinds of wounds. We report a case where the perpetrator argued he had given a circular blow, unfortunately hitting the victim. The pieces of evidence are discussed.

    Incident power density is used as the dosimetric quantity to specify the restrictions on human exposure to electromagnetic fields at frequencies above 3 or 10 GHz in order to prevent excessive temperature elevation at the body surface. However, international standards and guidelines have different definitions for the size of the area over which the power density should be averaged. This study reports computational evaluation of the relationship between the size of the area over which incident power density is averaged and the local peak temperature elevation in a multi-layer model simulating a human body. Three wave sources are considered in the frequency range from 3 to 300 GHz: an ideal beam, a half-wave dipole antenna, and an antenna array. 1D analysis shows that averaging area of 20 mm  ×  20 mm is a good measure to correlate with the local peak temperature elevation when the field distribution is nearly uniform in that area. The averaging area is different from recommendations in the current international standards/guidelines, and not dependent on the frequency. For a non-uniform field distribution, such as a beam with small diameter, the incident power density should be compensated by multiplying a factor that can be derived from the ratio of the effective beam area to the averaging area. The findings in the present study suggest that the relationship obtained using the 1D approximation is applicable for deriving the relationship between the incident power density and the local temperature elevation.

    Leishmune, the first prophylactic vaccine licensed against canine visceral leishmaniasis (CVL), has been used in Brazil since 2004, where seropositive dogs are sacrificed in order to control human visceral leishmaniasis (VL). We demonstrate here that vaccination with Leishmune does not interfere with the serological control campaign (110,000 dogs). Only 1.3% of positivity (76 among 5860) was detected among Leishmune uninfected vaccinees. We also analyzed the possible additive effect of Leishmune vaccination over dog culling, on the decrease of the incidence of CVL and VL in two Brazilian endemic areas, from 2004 to 2006. In Araçatuba, a 25% of decline was seen in CVL with a 61% decline in human cases, indicating the additive effect of Leishmune vaccination of 5.7% of the healthy dogs (1419 dogs), on regular dog culling. In Belo Horizonte (BH), rising curves of canine and human incidence were observed in the districts of Barreiro, Venda Nova and Noroeste, while the canine and human incidence of Centro Sul, Leste, Nordeste, Norte, Pampulha and Oeste, started to decrease or maintained a stabilized plateau after Leishmune vaccination. Among the districts showing a percent decrease of human incidence (-36.5%), Centro Sul and Pampulha showed the highest dog vaccination percents (63.27% and 27.27%, respectively) and the lowest dog incidence (-3.36% and 1.89%, respectively). They were followed by Oeste, that vaccinated 25.30% of the animals and experienced an increase of only 12.86% of dog incidence and by Leste and Nordeste, with lower proportions of vaccinees (11.72% and 10.76%, respectively) and probably because of that, slightly higher canine incidences (42.77% and 35.73%). The only exception was found in Norte district where the reduced human and canine incidence were not correlated to Leishmune vaccination. Much lower proportions of dogs were vaccinated in Venda Nova (4.35%), Noroeste (10.27%) and Barreiro (0.09%) districts, which according to that exhibited very

    Background Disease maps can serve to display incidence rates geographically, to inform on public health provision about the success or failure of interventions, and to make hypothesis or to provide evidences concerning disease etiology. Poisson kriging was recently introduced to filter the noise attached to rates recorded over sparsely populated administrative units. Its benefit over simple population-weighted averages and empirical Bayesian smoothers was demonstrated by simulation studies using county-level cancer mortality rates. This paper presents the first application of Poisson kriging to the spatial interpolation of local disease rates, resulting in continuous maps of disease rate estimates and the associated prediction variance. The methodology is illustrated using cholera and dysentery data collected in a cholera endemic area (Matlab) of Bangladesh. Results The spatial analysis was confined to patrilineally-related clusters of households, known as baris, located within 9 kilometers from the Matlab hospital to avoid underestimating the risk of disease incidence, since patients far away from the medical facilities are less likely to travel. Semivariogram models reveal a range of autocorrelation of 1.1 km for dysentery and 0.37 km for cholera. This result translates into a cholera risk map that is patchier than the dysentery map that shows a large zone of high incidence in the south-central part of the study area, which is quasi-urban. On both maps, lower risk values are found in the Northern part of the study area, which is also the most distant from the Matlab hospital. The weaker spatial continuity of cholera versus dysentery incidence rates resulted in larger kriging variance across the study area. Conclusion The approach presented in this paper enables researchers to incorporate the pattern of spatial dependence of incidence rates into the mapping of risk values and the quantification of the associated uncertainty. Differences in spatial patterns, in

    Objective Schizophrenia is associated with an increase in the risk of both homicide and suicide. The objectives of this study were to systematically review all published articles that examined the relation between neurocognitive deficits and suicidal or homicidal behaviours in schizophrenia, and to identify vulnerabilities in suicidal and homicidal behaviour that may share a common pathway in schizophrenia. Methods: A systematic review of the literature was performed using MEDLINE to include all studies published up to August 31, 2012. Results: Among the 1760 studies, 7 neuropsychological and 12 brain imaging studies met the selection criteria and were included in the final analysis. The neuropsychological and functional neuroimaging studies were inconclusive. The structural imaging studies reported various alterations in patients with schizophrenia and a history of homicidal behaviour, including: reduced inferior frontal and temporal cortices, increased mediodorsal white matter, and increased amygdala volumes. Patients with a history of suicidal acts showed volumetric reductions in left orbitofrontal and superior temporal cortices, while right amygdala volume was increased, though, these findings have rarely been replicated. Finally, no study has directly compared neurocognitive markers of suicidal and homicidal risk. Conclusion: These results suggest that brain alterations, in addition to those associated with schizophrenia, may predispose some patients to a higher risk of homicide or suicide in particular circumstances. Moreover, some of these alterations may be shared between homicidal and suicidal patients. However, owing to several limitations, including the small number of available studies, no firm conclusions can be drawn and further investigations are necessary. PMID:24444320

    This article is a descriptive epidemiological study of deaths by homicide in Latin American countries (Argentina, Brazil, Colombia and Mexico) from 1990 to 2007. Deaths due to external causes and homicides, as codified in the 9th and 10th revisions of the International Classification of Diseases/ICD, were analyzed considering sex, age and manner of assault. The numbers, ratios and adjusted rates for deaths by homicide are presented. A linear regression model was used to ascertain the trend of homicide rates by age group. During the period, 4,086,216 deaths from external causes and 1,432,971 homicides were registered in these countries. Deaths from external causes rose 54.5% in Argentina but fell in the other countries (37% in Mexico, 31.8% in Colombia, and 8.1% in Brazil). The ratio for deaths by homicide for both sexes was 9.1 in Colombia, 4.4 in Brazil and 1.6 in Mexico, using the Argentinian rates as a benchmark. There were differences in the evolution of homicide rates by age and sex in the countries: the rate rose in Brazil and fell in Colombia for all age groups. The need to prioritize young males in public policies related to health care and prevention is stressed, as well as the need for the region to adopt inclusive policies and broaden and consolidate democracy and the rights of inhabitants.

    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.

    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.

    Numerous investigations indicate a close link between violent behavior, homicide (murder) and alcohol intoxication. With increased frequency of drinking and the chronic consummation of alcohol, the risk of the fatal outcome or homicide and victimization caused by violence is more likely to occur. Studies conducted on convicted murderers suggested that about half of them were under the heavy influence of alcohol at the time of perpetration of murder. The sample in this survey consisted of 177 male offenders which committed criminal act of murder in Croatia from the year of 1990 until 2007 (capital murder and attempted murder). All were assigned for the forensic psychiatric evaluation by the Criminal Justice System (Court of Law) at the Department of Forensic Psychiatry, Neuropsychiatric Hospital, Popovaca, Croatia. For the purpose of this work the sample is divided in two groups of subjects: 1) offenders which were intoxicated at the time of murder and committed offence on intoxicated victim 2) offenders who were sober and committed offence on sober victims. Groups are compared according to the variables of crime and history of alcohol abuse. On the basis of obtained results we can conclude that there are significant differences in relation to the variables and modalities of criminal offence between two groups of offenders and victims. We could conclude that alcohol intoxication in offenders and victims at the time of murder could strongly affect the modalities of murder.

    The interpretation of medicolegal findings in homicide is an important tool of case profiling (so-called "operative case analysis"). In 17 cases of "multiple homicides" involving 22 offenders (21 males, 1 female; mean age 33 years) and 45 victims (21 males, 24 females; mean age 35 years; 41 fatalities, 4 survivors), the autopsy reports and the prosecution authorities' files were retrospectively analysed with regard to individual characteristics of perpetrators and victims, circumstances, and mode of commitment in order to comprehensively characterise relevant forensic and criminologic aspects. 31 victims were found to belong to the close social environment of the perpetrator, and 32 killings were committed in the victim's, perpetrator's or the joint flat. The main motives included greed (n = 7), personal conflicts (n = 5) and concealing of a crime (n = 9). The relevant injuries were attributable to gunshot wounds (n = 13), sharp force (n = 11), blunt force (n = 3), ligature strangulation (n = 3), smothering (n = 6), fire/carbon monoxide (n = 2) and combined impacts (n = 7). In 12 victims, defense injuries were found. The blood alcohol concentration exceeded 1.5 g/l in 5 victims. In 5 offenders, a psychiatric impairment of juridical responsibility was assessed (and 20 German criminal code, n = 1, psychosis; and 21 German criminal code, n = 4; acute alcohol intoxication). As far as data were available, 16 crimes were judged as murder, 12 as manslaughter and one as physical injury with fatal outcome.

    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

    OBJECTIVE: Homicide and suicide are intentional acts of violence that disproportionately involve firearms. Much more effort has been devoted to the ecological study of homicide; methods that have been developed to better understand and subsequently prevent homicide may be applicable to suicide. The purpose of the present study was to compare the occurrence of firearm homicide and firearm suicide using routine activity theory as a framework for analysis. METHODS: Detailed mortality data pertaining to decedents, their neighborhoods, and use of firearms were collected from 1994 to 1998 for the counties containing and surrounding three small to medium-sized U.S. cities. Data from a total of 468 neighborhoods that collectively experienced 1,025 intentional deaths from firearms (396 firearm homicides and 629 firearm suicides) were analyzed. RESULTS: Firearm homicide was consistently associated with out-of-home, nighttime activity in neighborhoods where many people were likely to be coming and going. In an opposite-but-equal fashion, firearm suicide was consistently associated with in-home, daytime activity in out-of-the-way neighborhoods. CONCLUSIONS: Firearm homicide and firearm suicide were found to be consistently associated with markers of routine activity in all three cities, albeit in an opposite-but-equal manner. Because firearm suicides very often occur as lonely events in lonely neighborhoods, they may go under-noticed relative to firearm homicides. More awareness and additional public health studies of firearm suicide, in tandem with firearm homicide, should be pursued to better identify individuals and neighborhoods that are at greatest risk of experiencing each event.

    Previous studies have shown decreasing child homicide rates in many countries - in Sweden mainly due to a drop in filicide-suicides. This study examines the rate of child homicides during 21 years, with the hypothesis that a decline might be attributable to a decrease in the number of depressive filicide offenders (as defined by a proxy measure). In addition, numerous characteristics of child homicide are presented. All homicide incidents involving 0-14-year-old victims in Sweden during 1992-2012 (n = 90) were identified in an autopsy database. Data from multiple registries, forensic psychiatric evaluations, police reports, verdicts and other sources were collected. Utilizing Poisson regression, we found a 4% annual decrease in child homicides, in accordance with prior studies, but no marked decrease regarding the depressive-offender proxy. Diagnoses from forensic psychiatric evaluations (n = 50) included substance misuse (8%), affective disorders (10%), autism-spectrum disorders (18%), psychotic disorders (28%) and personality disorders (30%). Prior violent offences were more common among offenders in filicides than filicide-suicides (17.8% vs. 6.9%); and about 20% of offenders in each group had previously received psychiatric inpatient care. Aggressive methods of filicide predominated among fathers. Highly lethal methods of filicide (firearms, fire) were more commonly followed by same-method suicide than less lethal methods. Interestingly, a third of the extra-familial offenders had an autism-spectrum disorder. Based on several findings, e.g., the low rate of substance misuse, the study concludes that non-traditional risk factors for violence must be highlighted by healthcare providers. Also, the occurrence of autism-spectrum disorders in the present study is a novel finding that warrants further investigation.

  12. Church, place, and crime: Latinos and homicide in new destinations.

    Latinos are moving beyond traditional areas and settling in new, potentially disorganized destinations. Without an established immigrant community, new destinations appear to rely more on the local religious ecology to regulate community life and to keep crime low. We examine the link between religious ecology and Latino homicide victimization for traditional and new destination counties. We observe four findings. (1) A Catholic presence has no effect on Latino violence in the old and well-organized traditional settlement areas. But in new Latino settlement areas, a Catholic presence substantially lowers violence against Latinos. In contrast, mainline Protestantism is linked to high levels of violence against Latinos in new destinations. (2) Previous claims that Latino communities are safe do not apply to new destinations, where Latinos are murdered at a high rate. (3) Previous claims that areas with high Latino immigration are safe for Latinos are not true for new destinations. (4) New Latino destinations offer little insulation from the effects of economic deprivation on violence. We discuss the implications of the findings.

    Background Residents of geothermal areas have higher incidence of non-Hodgkin’s lymphoma, breast cancer, prostate cancer, and kidney cancers than others. These populations are exposed to chronic low-level ground gas emissions and various pollutants from geothermal water. The aim was to assess whether habitation in geothermal areas and utilisation of geothermal water is associated with risk of cancer according to duration of residence. Methods The cohort obtained from the census 1981 was followed to the end of 2013. Personal identifier was used in record linkage with nation-wide emigration, death, and cancer registries. The exposed population, defined by community codes, was located on young bedrock and had utilised geothermal water supply systems since 1972. Two reference populations were located by community codes on older bedrock or had not utilised geothermal water supply systems for as long a period as had the exposed population. Adjusted hazard ratio (HR), 95% confidence intervals (CI) non-stratified and stratified on cumulative years of residence were estimated in Cox-model. Results The HR for all cancer was 1.21 (95% CI 1.12–1.30) as compared with the first reference area. The HR for pancreatic cancer was 1.93 (1.22–3.06), breast cancer, 1.48 (1.23–1.80), prostate cancer 1.47 (1.22–1.77), kidney cancer 1.46 (1.03–2.05), lymphoid and haematopoietic tissue 1.54 (1.21–1.97), non-Hodgkin´s lymphoma 2.08 (1.38–3.15) and basal cell carcinoma of the skin 1.62 (1.35–1.94). Positive dose-response relationship was observed between incidence of cancers and duration of residence, and between incidence of cancer and degree of geothermal/volcanic activity in the comparison areas. Conclusions The higher cancer incidence in geothermal areas than in reference areas is consistent with previous findings. As the dose-response relationships were positive between incidence of cancers and duration of residence, it is now more urgent than before to investigate

  14. 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.

  15. Intimate Partner Violence: A Rare Case of Reciprocal Homicide.

    2017-03-23

    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.

  17. A test of two typologies of sexual homicide.

    Sewall, Lindsay A; Krupp, Daniel Brian; Lalumière, Martin L

    2013-02-01

    Published typologies of sexual homicide lack theoretical grounding and empirical support. They also conceptualize the phenomenon of sexual homicide as somewhat discrete, though offenders are not typically specialists. Here, we propose a model that situates the phenomenon of sexual killing into broader categories of antisocial behavior, positing three types of perpetrators of serial sexual homicides: competitively disadvantaged, psychopathic, and sadistic offenders. Using biographical data of 82 serial sexual homicide offenders, we tested our model as well as the influential organized/disorganized model. Principal components analysis produced five components consisting of offender and offense characteristics, and cluster analysis revealed three distinct groups of perpetrators (sadistic offenders, competitively disadvantaged offenders, and slashers), as well as a fourth, heterogeneous group; this cluster solution, however, may be unstable. In summary, there is only mixed support for either model.

  18. An analysis of Korean homicide crime-scene actions.

    2007-11-01

    Recent studies have focused on how different styles of homicides will be reflected in the different types of behaviors committed by offenders at a crime scene. It is suggested that these different types of behaviors best be understood using two frameworks, expressive/instrumental aggression and planned/unplanned violence, to analyze the way the offender acts at the crime scene. Multidimensional analysis is carried out on the crime-scene actions of 70 Korean homicides. The proposed frameworks are found to be a useful way of classifying homicide offenses, assigning 80% of homicides to a dominant theme. Results also indicate that behavioral differences can be related to the differences in the offender-victim relationship. Finally, implications and suggestions for future research are discussed.

    2006-12-01

    Controversies exist about the diagnostic validity of sexual sadism and its relation to sadistic personality disorder in sex offenders. The aim of this study was to investigate which diagnostic, developmental, and criminal characteristics differentiate sexual sadistic from non-sadistic sexual homicide perpetrators. Psychiatric court reports on 166 men who had committed a sexual homicide were evaluated regarding psychiatric, sexual and criminal history. Sixty-one offenders (36.7%) with sexual sadism (SeSd) were compared with 105 (63.3%) offenders without this diagnosis (NSeSd). Besides the sexual sadistic symptoms, there were seven factors that discriminated best between the two groups (sexual masochism, sadistic personality disorder, isolation in childhood, multiple sexual homicide, previous rape, previous tendencies for similar behavior, and long duration of the homicidal act). Sexual sadism is connected with circumscribed other characteristics and has to be considered in risk assessment and treatment of sex offenders.

    1992-12-01

    We investigated the object relations of adolescents who committed homicide. A clinical sample of 55 adolescents who committed homicide did not differ from a comparison group of nonviolent delinquents on Rorschach measures of object differentiation, mutuality of autonomy, and aggressive content. However, the subgroup of adolescents who committed homicides in the context of another crime (e.g., robbery or burglary) did manifest significantly lower object relations (poorer object differentiation and more victim responses) than the subgroup of adolescents whose homicides were committed in the context of an interpersonal conflict or dispute with the victim. These findings support the need for differentiated classification of violent individuals as urged by Megargee (1970) over 20 years ago.

  1. Ritual and signature in serial sexual homicide.

    PubMed

    Schlesinger, Louis B; Kassen, Martin; Mesa, V Blair; Pinizzotto, Anthony J

    2010-01-01

    Ritual and signature are fantasy-driven, repetitive crime scene behaviors that have been found to occur in serial sexual homicide. Notwithstanding numerous anecdotal case reports, ritual and signature have rarely been studied empirically. In a national sample of 38 offenders and their 162 victims, we examined behavioral and thematic consistency, as well as the evolution and uniqueness of these crime scene actions. The notion that serial sexual murderers engage in the same rituals and leave unique signatures at every scene was not supported by our data. In fact, the results suggest that the crime scene conduct of this group of offenders is fairly complex and varied. Implications of these findings for forensic assessments and criminal investigations are discussed.

    Certain methods of homicide used by the Italian Mafia are intended to have an admonitory significance. One such method is the so-called "incaprettamento." This study analyzes 18 cases of homicidal ligature strangulation in which the body was found in this typical position. The circumstances of the crime and the macroscopic and microscopic evidence were evaluated to determine whether or not the ligatures on the wrists and ankles were placed antemortem or postmortem.

    The act of homicide may influence the worldviews of children and adolescents. Problematic beliefs of uncertainty, inadequacy, perceiving the world as dangerous, self-denial, and lack of control can contribute to complicated grief in children and adolescents, and can potentially disrupt their normal psychosocial growth and development. Mental health professionals' understanding of grief after the homicide of a family member enhances their ability to intervene with and support young people struggling to cope with and adapt to a sudden loss.

  5. Prospective study of asbestos-related diseases incidence cases in primary health care in an area of Barcelona province

    Background Asbestos related diseases include a number of conditions due to inhalation of asbestos fibres at work, at home or in the environment, such as pleural mesothelioma, asbestosis and calcified pleural plaques. Few epidemiological studies have established the incidence of asbestos related diseases in our area. The present proposal is based on a retrospective study externally funded in 2005 that is currently taking place in the same area and largely carried out by the same research team. The aim of the study is to achieve a comprehensive and coordinated detection of all new cases of Asbestos Related Diseases presenting to primary care practitioners. Methods/design This is a multicentre, multidisciplinary and pluri-institutional prospective study. Setting 12 municipalities in the Barcelona province within the catchment area of the health facilities that participate in the study. Sample This is a population based study, of all patients presenting with diseases caused by asbestos in the study area. Measurements A clinical and epidemiological questionnaire will be filled in by the trained researchers after interviewing the patients and examining their clinical reports. Discussion Data on the incidence of the different Asbestos Related Diseases in this area will be obtained and the most plausible exposure source and space-time-patient profile will be described. The study will also improve the standardization of patient management, the coordination between health care institutions and the development of preventive activities related with asbestos exposure and disease.

    2008-01-01

    Previous research indicates that the killing method used in homicides may reflect the motivation of the offender and qualities of the victim-offender relationship. The effect of gender and sexual orientation of intimate partner homicide offenders (N = 51,007) was examined with respect to the brutality of killing methods. Guided by previous research and theory, it was hypothesized that homicide brutality will vary with the offender's sexual orientation and gender, such that the percentage of killings coded as brutal will be higher for (a) gay and lesbian relative to heterosexual relations, (b) men relative to women, (c) gay relative to heterosexual men, and (d) lesbian relative to heterosexual women. The rates of intimate partner homicide were also hypothesized to vary with the gender of the partners, such that (a) homicide rates will be higher in gay relative to heterosexual and lesbian couples and (b) homicide rates will be lowest in lesbian couples. The results support all but one prediction derived from the two hypotheses. We predicted that men would kill their partners more brutally than would women, but the results indicate that the opposite is true.

    The aim of this study was to investigate the occurrence and characteristics of homicide-suicide events in Southwestern Croatia from 1986-2009 relying on autopsy reports of the Department of Forensic Medicine and Criminalistics, Rijeka and police records. A total of 17 cases involving 19 victims were identified. The perpetrators were most often men (82%), living in a spousal relationship with the victim. In 76.5% cases, suicide was committed immediately after homicide, and the same mean (most often an illegal firearm) was used for both. After examining the belongings of those involved in homicide-suicides, two factors differentiated our study from others, i.e. more victims and perpetrators were from the lower socioeconomic class and explosives were used in two homicide-suicide (12%) cases. The greater frequency of explosive used in homicide-suicide events may be a result of factors associated with the recent war fought in Croatia. These data prove the influence of sociological, historical and also political factors on the characteristics of a rare event such as homicide-suicide.

    2015-01-01

    In the literature on bereavement, claims are made that homicidal loss is associated with posttraumatic stress reactions, depression, and other severe mental health problems. It is surprising that only a few studies have investigated the nature and prevalence of emotional symptoms following homicidal bereavement and a reference to systematic, empirical research is seldom provided. This article reviews the available literature to investigate whether these claims have empirical evidence. Three databases were searched to identify relevant studies. This approach was supplemented with a bibliography search. Eligible studies included English-language peer-reviewed articles that assessed psychopathology in the homicidally bereaved, as defined in the Diagnostic and Statistical Manual of Mental Disorders. Of the 360 potentially relevant articles, 8 studies (13 references) met predefined inclusion criteria. Homicide-related psychopathology among the bereaved assessed in these studies includes posttraumatic stress disorder (PTSD), depression, complicated grief, and substance abuse. Prevalence of lifetime homicide-related PTSD varied from 19.1% to 71% across studies. Current PTSD varied between 5.2% and 6%. The reviewed literature was inconclusive regarding the course of symptoms over time and the severity of psychopathology among the homicidally bereaved, compared to individuals bereaved by other causes of death. A comparison of the nature and prevalence of psychopathology between studies was complicated by unequal sample sizes and type, recruitment strategy, study design, and time since loss. Limitations of the included studies are discussed, as well as implications for clinical practice, policy, and future research.

    1999-01-01

    Objectives—The purpose of this investigation was to identify population groups at highest risk of using a firearm in a fatal incident. Setting—Los Angeles County (California, USA). Methods—Data were gathered from vital statistics reports and law enforcement records on the characteristics of suicide victims (n = 4799) and homicide suspects (n = 5369) from 1990 through 1994. Logistic regression was used to identify characteristics of the actor/perpetrator that were associated with firearm use. Results—Persons less than 21 years old and males were more likely to use a firearm to kill themselves or someone else. Even when their other demographic attributes and characteristics of the incident itself were taken into consideration, persons under the age of 18 were substantially more likely than those 21 or more years old to use a firearm in the commission of a homicide (adjusted odds ratio = 2.59). Asians were less likely than white people to use a firearm in the commission of a suicide, whereas black people, Hispanics, and Asians were more likely than whites to use a firearm in the commission of a homicide. Conclusions—The US enacts and enforces some policies differentially by age. These data support the idea that such an approach may be warranted when addressing fatalities associated with the use of a firearm. Of particular interest, given minimum age requirements for firearm purchases, is the source of the weapons themselves. PMID:10628917

  10. Murder by structure: dominance relations and the social structure of gang homicide.

    PubMed

    Papachristos, Andrew V

    2009-07-01

    Most sociological theories consider murder an outcome of the differential distribution of individual, neighborhood, or social characteristics. And while such studies explain variation in aggregate homicide rates, they do not explain the social order of murder, that is, who kills whom, when, where, and for what reason. This article argues that gang murder is best understood not by searching for its individual determinants but by examining the social networks of action and reaction that create it. In short, the social structure of gang murder is defined by the manner in which social networks are constructed and by people's placement in them. The author uses a network approach and incident-level homicide records to recreate and analyze the structure of gang murders in Chicago. Findings demonstrate that individual murders between gangs create an institutionalized network of group conflict, net of any individual's participation or motive. Within this network, murders spread through an epidemic-like process of social contagion as gangs evaluate the highly visible actions of others in their local networks and negotiate dominance considerations that arise during violent incidents.

    Bone health was assessed for inhabitants of an area affected by the Fukushima nuclear plant incident. Osteoporotic patients, who had been treated with active vitamin D3 and/or bisphosphonate at Soma Central Hospital before the Fukushima incident, were enrolled. Changes in bone turnover markers and bone mineral density were retrospectively analyzed. Serum levels of a bone resorption marker, serum type I collagen cross-linked N-telopeptide were decreased in all the treated groups, whereas those of a bone formation marker, bone-specific alkaline phosphatase, were increased. Accordingly, bone mineral density, estimated by dual-energy X-ray absorptiometry, was increased in the lumbar spine of all groups, but bone mass increase in the proximal femur was detected only in the group treated with the two agents in combination. From the degree of these parameter changes, the antiosteoporotic treatments looked effective and were equivalent to the expected potency of past observations. At this stage, the present study implies that the Fukushima nuclear incident did not bring an acute risk to bone health in the affected areas.

    Objective of the study was to evaluate the annual incidence and distribution of autoimmune connective tissue diseases and vasculitides during 2010. All units practicing rheumatology in the Northern Savo area, Finland, participated in the study by collecting data on newly diagnosed adult patients with autoimmune connective tissue disease or vasculitis over 1-year period. Seventy-two cases with autoimmune connective tissue disease were identified. The annual incidence rates were as follows: systemic lupus erythematosus 3.4/100,000 (95 % CI 1.4-7.0), idiopathic inflammatory myopathies 1.9 (0.5-5.0), systemic sclerosis 4.4 (2.0-8.3), mixed connective tissue disease 1.0 (0.1-3.5), Sjögren's syndrome 10.7 (6.7-16.1) and undifferentiated connective tissue disease 13.6 (9.0-19.6). The annual incidence rates among vasculitis category were as follows: antineutrophil cytoplasmic antibody-associated vasculitis 1.5/100,000 (95 % CI 0.3-4.3), central nervous system vasculitis 0.5 (0-2.7) and Henoch-Schönlein purpura 1.5 (0.3-4.3). The annual incidence of giant cell arteritis in the age group of 50 years or older was 7.5/100,000 (95 % CI 3.2-14.8). The longest delay from symptom onset to diagnosis occurred in systemic sclerosis. The incidences of autoimmune connective tissue diseases and vasculitides were comparable with those in published literature. The present study showed female predominance in all connective tissue diseases, excluding idiopathic inflammatory muscle diseases and mean age at onset of disease around 50 years of age. Despite improved diagnostic tools, diagnostic delay is long especially among patients with systemic sclerosis.

    This study focused on the annual cumulative incidence (ACI) of disabling work-related musculoskeletal disorders affecting the neck and/or upper limbs (ULMSD) among workers covered by the National Social Insurance System in the city of Salvador, Bahia State, Brazil. Cases were workers who received disability compensation benefits when unable to work due to ULMSD, during the year 2008. The data were obtained from the administrative systems of the National Social Insurance Institute and Ministry of Labor and Employment. ACI was 15 per 10,000 workers. Increased ACI of ULMSD was associated with female gender, lower income, and work in financial activities or manufacturing. Women earning the minimum wage (US$ 64.00 per month) or less had the highest ACI of ULMSD (123 per 10,000), suggesting inequalities in the occurrence of these disorders. The study indicates the need to prioritize preventive actions focusing on ergonomics and work organization, early diagnosis, treatment, and rehabilitation.

    Since an overarching goal of Healthy People 2010 was to eliminate health disparities, we determined temporal trends in socioeconomic disparities in five breast-cancer indicators (in situ, stage I, lymph-node positive, and locally advanced breast-cancer incidence, and breast-cancer mortality) by county socioeconomic deprivation using 1988-2005 population-based breast-cancer data. Using 1988-2005 data from women aged 40 and older from 200 counties in the Surveillance, Epidemiology, and End Results program, we examined trends in temporal disparities in the five breast-cancer indicators across quartiles of county socioeconomic deprivation. County-level trends were summarized using the estimated annual percentage change. Observed county rates were smoothed using Bayesian hierarchical spatiotemporal methods to calculate measures of absolute and relative disparity (using absolute and relative concentration indices) and their changes over time. Large increases in in situ breast cancer rates since 1988 were observed for each of the deprivation quartiles. Absolute and relative disparity both increased over time, suggesting increasing disparities across levels of county deprivation. Absolute and relative concentration indices were near zero for the other four breast-cancer indicators, suggesting no disparities among the four quartiles of county deprivation during 1988-2005. Efforts to target counties aimed at increasing breast-cancer screening based on their level of deprivation will not likely be beneficial.

    2009-12-01

    Golestan Province, located in the south-east littoral of the Caspian Sea in northern Iran, has one of the highest rates of oesophageal cancer (OC) in the world. We review the epidemiologic studies that have investigated the epidemiologic patterns and causes of OC in this area and provide some suggestions for further studies. Oesophageal squamous cell carcinoma (OSCC) constitutes over 90% of all OC cases in Golestan. In retrospective studies, cigarettes and hookah smoking, nass use (a chewing tobacco product), opium consumption, hot tea drinking, poor oral health, low intake of fresh fruit and vegetables, and low socioeconomic status have been associated with higher risk of OSCC in Golestan. However, the association of tobacco with OSCC in this area is not as strong as that seen in Western countries. Alcohol is consumed by a very small percentage of the population and is not a risk factor for OSCC in this area. Other factors, such as polycyclic aromatic hydrocarbons, N-nitroso compounds, drinking water contaminants, infections, food contamination with mycotoxins, and genetic factors merit further investigation as risk factors for OSCC in Golestan. An ongoing cohort study in this area is an important resource for studying some of these factors and also for confirming the previously found associations.

    2013-11-01

    Xuanwei and Fuyuan, two counties located in southwest China, are areas with known high lung cancer incidence. Pollution relative to coal combustion, especially serious air pollution generated by burning smoky coals in unvented households, has been thought to be the most predominant cause. Possible inorganic carcinogenic matter including radon in air and arsenic, lead, chromium, cadmium, nickel, and beryllium in water, soil, and coal were sampled and examined to find the current pollution status, distributions, characteristics, and relationships to the lung cancer incidence. The concentrations of mercury in air of Xuanwei and Fuyuan ranged from 1.7 to 205.3 ng/m3 (indoor), 1.3 to 7.5 ng/m3 (ambient). No radon concentration exceeded the World Health Organization standard. Results indicated that household stove improvement by changing stoves from unvented to vented obviously alleviated the indoor air pollution of carcinogenic metals. Most of the carcinogenic metals were also found at very low levels in water and soil, which therefore had little influence on human health. Concentrations of these elements at different sites did not vary in any relation to lung cancer incidence. The study described in this article added basic data; the results of the authors' study will be helpful in determining pollution status and to future studies on the etiology of lung cancer.

The dose of radiation to the bones of the target area was 5,000 cGy. The patients showed no signs of metastases at bone scintigraphy performed in connection with the treatment. In an average of 34 months after finishing radiotherapy, the patients developed metastases at bone scintigraphy. The pattern was similar in all patients. The treated target area appeared as a cold zone surrounded by more or less homogenously and strongly increased activity of the axial skeleton, characteristic of bone metastases. Radiography, which was performed in 11 patients, confirmed widespread metastatic disease sparing the target area. This was interpretated as bone metastasis being precluded by the irradiation. The most probable explanation of this finding is eradication in situ of distant micrometastases already present in the bone marrow at the time of treatment. An alternate explanation is a reduced implantation of later seeded blood-born metastases as an effect of the irradiation. The characteristic pattern of this phenomenon must be recognized at bone scintigraphy.

    Background: The Pennsylvania Department of Health established a registry of the Three Mile Island (TMI) nuclear power plant accident in 1979. Over 93% of the population present on the day of the accident within a 5-mile radius was enrolled and interviewed. We used the registry to investigate the potential cancer risk from low-dose radiation exposure among the TMI population. Methods: Cancer incidence data among the TMI cohort were available from 1982 to 1995. Because more than 97% of the population were white and few cancer cases were reported for those younger than 18 years of age, we included whites of age 18 years and older (10,446 men and 11,048 women) for further analyses. Cox regression models were used to estimate the relative risk (RR) per 0.1 m Sv and 95% confident interval (CI) of cancer by radiation-related exposures. The cancers of interest were all malignant neoplasms, cancer of bronchus, trachea, and lung, cancer of lymphatic and hematopoietic tissues, leukemia, and female breast. Results: Among men and women, there was no evidence of an increased risk for all malignant neoplasms among the TMI cohort exposed to higher maximum and likely {gamma} radiation (RR=1.00, 95% CI=0.97, 1.01 and RR=0.99, 95% CI=0.94, 1.03, respectively) after adjusting for age, gender, education, smoking, and background radiation. Elevation in risk was noted for cancer of the bronchus, trachea, and lung in relation to higher background radiation exposure (RR=1.45, 95% CI=1.02-2.05 at 8.0-8.8 {mu}R/h compared to 5.2-7.2 {mu}R/h). An increased risk of leukemia was found among men exposed to higher maximum and likely {gamma} radiation related to TMI exposure during the ten days following the accident (RR=1.15, 95% CI=1.04, 1.29 and RR=1.36, 95% CI=1.08, 1.71, respectively). This relationship was not found in women. Conclusion: Increased cancer risks from low-level radiation exposure within the TMI cohort were small and mostly statistically non-significant. However, additional

    Homicides committed by insane offenders have been rarely investigated from the forensic point of view in a comprehensive and detailed manner. The objective of the study was to describe and characterize the modus operandi and personal characteristics in cases when more than one victim was killed and the perpetrator was deemed insane in judicial proceedings. Differences between single and multiple-vitim homicides in the population of insane murderers were also examined. Complete dossiers and forensic examination reports of 21 homicide victims killed by 9 individuals were retrospectively analyzed. The comparative control group consisted of 41 cases with only one victim killed by a single insane perpetrator. The offence and offender variables were subjected to a comparative statistical analysis. The results indicated some specific factors that can be regarded as distinctive features more commonly observed in multiple vs. single victim killings perpetrated by insane individuals. There was a significant correlation between, psychosis with depressive delusions, emotional/affective motivation, common domicile and a positive relationship between the perpetrator and the victim, infanticide committed in the perpetrator's offspring, actions with elements of planning, attacking victims while asleep, attacking from the back rather than from the front, concentration and clustering of injuries in one region of the body and multiple psychotic homicides. The results and conclusions of this study can provide practical, useful implications for homicide investigations, offender profiling or forensic psychiatric and psychological evidence.

    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.

    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.

    Objective We aimed to assess the risk factors associated with homicidal behaviour in male patients diagnosed with schizophrenia. Methods In a period of 1 year, male schizophrenia cases between 18-65 years of age (n = 210) were included. The clinical evaluation included the Positive and Negative Syndrome Scale (PANSS) and Overt Aggression Scale (OAS). The patients were divided into three groups in terms of violent behaviour history: (1) homicide group (n = 30), (2) a violent act resulting in serious injury (n = 71), (3) control group (patients without a history of a violent act) (n = 109). Results Lower level of education, rural residence, being unemployed and living alone were found to be significantly more common in patients who had committed a violent act compared to the schizophrenia patients in the control group. In order to explore the predictive value of several factors associated with violent behaviour, a logistic regression model was used, and variables (shorter duration of education, living alone, and lack of insight) significantly predicted the presence of violent behaviour (murder and/or injury) (χ(2)=31.78, df = 12, p = 0.001). Conclusions In order to be able to determine causality of homicidal acts in schizophrenia patients, our significant findings between homicidal violence, non-homicidal violence and the control group would merit further attention and exploration in further studies.

    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.

    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.

    1995-10-06

    In Colombia, as in the United States, homicide occurs disproportionately among urban residents (1,2). Homicide rates in the city of Cali, Colombia (1994 population: 1,776,436), increased fivefold from 1985 through 1992, reaching levels of 100 per 100,000 persons. Because of this increase, in 1992 the city of Cali established the Development, Security, and Peace Program (DESEPAZ) to implement a series of strategies to prevent violence and improve security among the residents of Cali. An important element of this program was the establishment of a surveillance system to enable characterization of patterns and determinants of homicide to provide information to decision makers for formulating policies and programs. This report summarizes findings from this system for January 1993-May 1994.

    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.

    Exposure to crystalline silica (quartz) has been implicated as a potential cause of the high lung cancer rates in the neighbouring counties of Xuanwei and Fuyuan, China, where the domestic combustion of locally sourced "smoky" coal (a bituminous coal) is responsible for some of the highest lung cancer rates in the nation, irrespective of gender or smoking status. Previous studies have shown that smoky coal contains approximately twice as much quartz when compared to alternative fuels in the area, although it is unclear how the quartz in coal relates to household air pollution. Samples of ash and fine particulate matter (PM2.5) were collected from 163 households and analysed for quartz content by Fourier transformed infrared spectroscopy (FT-IR). Additionally, air samples from 12 further households, were analysed by scanning electron microscopy (SEM) to evaluate particle structure and silica content. The majority (89%) of household air samples had undetectable quartz levels (<0.2 μg/m(3)) with no clear differences by fuel-type. SEM analyses indicated that there were higher amounts of silica in the smoke of smoky coal than smokeless coal (0.27 μg/m(3) vs. 0.03 μg/m(3)). We also identified fibre-like particles in a higher concentration within the smoke of smoky coal than smokeless coal (5800 fibres/m(3) vs. 550 fibres/m(3)). Ash analysis suggested that the bulk of the quartz in smoky coal went on to form part of the ash. These findings indicate that the quartz within smoky coal does not become adequately airborne during the combustion process to cause significant lung cancer risk, instead going on to form part of the ash. The identification of fibre-like particles in air samples is an interesting finding, although the clinical relevance of this finding remains unclear.

    INTRODUCTION.: The present study investigates the relevance of genital abnormalities (GA) like cryptorchidism, hypospadias, and phimosis usually diagnosed in early childhood for the development of psychosexual problems and deficits in a sample of N = 163 convicted sexual homicide perpetrators. AIMS.: The first aim was to investigate the prevalence of early childhood GA in a sample of sexual homicide perpetrators. The second was to explore differences in the psychosexual development of participants with GA in early childhood compared with those without GA. It was expected that offenders with GA show specific problems in their psychosexual development compared with offenders without GA. METHODS.: The data for the present study were obtained by reanalyzing an existing database derived from a large-scale research project about sexual homicide. Using a predominantly exploratory design we, therefore, divided the total sample into two subgroups (with vs. without indicators of GA). MAIN OUTCOME MEASURES.: Main outcome measures were the number of sexual homicide perpetrators showing GA in early childhood and the differences of subjects with and without GA with regard to their psychosexual development (i.e., according to sexual deviant interests or sexual dysfunctions). RESULTS.: The prevalence of GA is substantially higher in this sample than epidemiological studies indicated in the normal population. This result provided first support for the importance of GA in the population of sexual homicide perpetrators. Further analyses indicate significant differences between both subgroups: Offenders with GA in early childhood showed indicators for more sexual dysfunctions (e.g., erectile dysfunction) in adulthood and a distinct tendency of more masochistic sexual interests. CONCLUSION.: Even if the exploratory design of the present investigation allows no causal conclusions between GA and sexual homicide offenses, the result provided support for the relevance of early

    This article gives a clinically oriented overview of forensically relevant forms of sexual sadism disorder and its specific relationship to sexual homicide. In sexual homicide perpetrators, peculiar patterns of sexual sadism may be a motivational pathway to kill. Sexual sadism increases the risk for reoffending in sexual offenders. Through psychotherapy and pharmacological interventions, treatment of sadistic sex offenders has to consider special characteristics that may be different from those of nonsadistic sex offenders. Many of these offenders share a combination of sexual sadistic motives and an intact self-regulation, sometimes combined with a high level of sexual preoccupation.

    Smoking and radon both cause lung cancer, and together the risk is significantly higher. UK public health campaigns continue to reduce smoking prevalence, and other initiatives identify houses with raised radon (radon-222) levels and encourage remedial action. Smoking prevalence and radon levels in the UK have been mapped at Primary Care Trust level. This paper extends that work, using a commercial socio-demographic database to estimate smoking prevalence at the postcode sector level, and to predict the population characteristics at postcode sector level for 87 postcode sectors in Northamptonshire. Likely smoking prevalence in each postcode sector is then modelled from estimates of the smoking prevalence in the different socio-economic groups used by the database. Mapping estimated smoking prevalence, radon potential and average lung cancer incidence for each postcode sector suggested that there was little correlation between smoking prevalence and radon levels, as radon potential was generally lower in urban areas in Northamptonshire, where the estimates of smoking prevalence were highest. However, the analysis demonstrated some sectors where both radon potential and smoking prevalence were moderately raised. This study showed the potential of this methodology to map estimated smoking prevalence and radon levels to inform locally targeted public health campaigns to reduce lung cancer incidence.

    Background/Aims Although indoor air pollution is a well-known risk factor for tuberculosis (TB), the possible link between outdoor air pollution and TB development has not been examined fully. We assessed the impact of outdoor air pollution on TB development in the Seoul metropolitan area, South Korea. Methods The mean concentrations of ambient particulate matter (PM) with an aerodynamic diameter ≤ 10 µm (PM10), O3, CO, NO2, and SO2 levels in Seoul, between January 1, 1997 and December 31, 2006, were determined. Furthermore, their association with the risk of developing TB after adjusting for socioeconomic status, between January 1, 2002 and December 31, 2006, was investigated. Results Between January 1, 2002 and December 31, 2006, a total of 41,185 TB cases were reported in Seoul. Concentrations of PM10, O3, CO, and NO2 were not associated with TB incidence in males or females. However, the interquartile increase in SO2 concentration was associated with a 7% increment in TB incidence (relative risk [RR], 1.07; 95% credible interval [CrI], 1.03 to 1.12) in males but not in females (RR, 1.02; 95% CrI, 0.98 to 1.07). Conclusions Long-term exposure to ambient SO2 increased the risk of TB in males. PMID:24648801

    Luminous phenomena and anomalous physical forces have been hypothesized to be generated by focal tectonic strain fields that precede earthquakes. If these geophysical processes exist, then their spatial and temporal density should be greatest during periods of protracted, localized UFO reports; they might be used as dosimetric indicators. Contemporary epidemiological data concerning the health risks of power frequency electromagnetic fields and radon gas levels (expected correlates of certain tectonic strain fields), suggest that increased incidence (odds ratios greater 1:3) of brain tumors and leukemia should be evident within flap areas. In addition the frequency of variants of temporal lobe lability, psychological depression and posttraumatic stress should be significantly elevated. UFO field investigators, because they have repeated, intermittent close proximity to these fields, are considered to be a particularly high risk population for these disorders. 22 references.

    This study examines a sample of 136 male and female juveniles charged with attempted homicide or homicide. The purpose of this study is to explore the differences between nondirect file male and female juvenile homicide offenders regarding individual, family, and crime circumstances. Findings suggest that compared to male juvenile offenders, female juvenile homicide offenders have higher rates of reported childhood abuse, more serious substance abuse, and mental health problems including suicidal ideations, depression, anxiety, anger, and irritability. Male juvenile homicide offenders reported higher rates of substance use than their female counterparts but the females had more serious substance abuse problems. Female juveniles were found to more often kill a person known to them and male homicide offenders were found to more often kill a stranger. These findings suggest strongly that male and female juvenile homicide offenders are dissimilar and require unique assessment and treatment.

    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.

    Puerto Rico detected the first confirmed case of chikungunya virus (CHIKV) in May 2014 and the virus rapidly spread throughout the island. The invasion of CHIKV allowed us to observe Aedes aegypti (L.) densities, infection rates, and impact of vector control in urban areas using CDC autocidal gravid ovitraps (AGO traps) for mosquito control over several years. Because local mosquitoes can only get the virus from infectious residents, detecting the presence of virus in mosquitoes functions as a proxy for the presence of virus in people. We monitored the incidence of CHIKV in gravid females of Ae. aegypti in four neighborhoods-two with three AGO traps per home in most homes and two nearby neighborhoods without AGO mosquito control traps. Monitoring of mosquito density took place weekly using sentinel AGO traps from June to December 2014. In all, 1,334 pools of female Ae. aegypti (23,329 individuals) were processed by real-time reverse transcription PCR to identify CHIKV and DENV RNA. Density of Ae. aegypti females was 10.5 times lower (91%) in the two areas with AGO control traps during the study. Ten times (90.9%) more CHIKV-positive pools were identified in the nonintervention areas (50/55 pools) than in intervention areas (5/55). We found a significant linear relationship between the number of positive pools and both density of Ae. aegypti and vector index (average number of expected infected mosquitoes per trap per week). Temporal and spatial patterns of positive CHIKV pools suggested limited virus circulation in areas with AGO traps.

    At 13:46 on March 11, 2011 (Beijing time), an earthquake of Mw=9.0 occurred in Japan. By comparing the tsunami data from Guanhekou marine station with other tsunami wave observation gathered from southeast coastal area of China, it was evident that, only in Guanhekou, the position of the maximum wave height appeared in the middle part rather than in the front of the tsunami wave train. A numerical model of tsunami propagation based on 2-D nonlinear shallow water equations was built to study the impact range and main causes of the special tsunami waveform discovered in Jiangsu coastal area. The results showed that nearly three-quarters of the Jiangsu coastal area, mainly comprised the part north of the radial sand ridges, reached its maximum tsunami wave height in the middle part of the wave train. The main cause of the special waveform was the special underwater topography condition of the Yellow Sea and the East China Sea area, which influenced the tsunami propagation and waveform significantly. Although land boundary reflection brought an effect on the position of the maximum wave height to a certain extent, as the limits of the incident waveform and distances between the observation points and shore, it was not the dominant influence factor of the special waveform. Coriolis force's impact on the tsunami waves was so weak that it was not the main cause for the special phenomenon in Jiangsu coastal area. The study reminds us that the most destructive wave might not appear in the first one in tsunami wave train.

    The aim of this study was to ascertain if a relationship between weapon choice and psychopathology existed. The perpetrators (103) were evaluated at the Department of Criminology and Forensic Psychiatry of the University of Bari in southern Italy. Psychiatric examination and psycho-diagnostic tests were administered for each of the perpetrators and a database was subsequently formulated. The results showed a significant correlation between some types of mental disorder and weapon choice. A strong correlation was found between delusional disorders and the use of sharp weapons, whereas depressive disorders were more strongly associated with asphyxia. Organic disorders were found to be highly correlated with the use of blunt instruments. In cases where the homicide was the result of an impulsive reaction, the use of sharp weapons was most often observed.

  12. An archival exploration of homicide--suicide and mass murder in the context of 19th-century American parricides.

    There has been little attempt to integrate contemporary studies of suicide and mass murder to homicide-suicides. The current research attempts to do so in the context of 19th-century parricides in America. This project uses archival records from The New York Times and the Chicago Tribune, 1851-1899, resulting in a total of 231 incidents. Our results indicate that parricides, mass murders, and suicides tended to originate as spontaneous acts, usually during the course of an argument, gathering momentum as the interaction unfolded. We contend that suicide is one way of alleviating threats to offender's loss of self-identity.

    High rates of psychotic disorder among special populations of homicide offenders, females, youth and the mentally disordered, have received much investigation. Personality disorder, especially antisocial personality disorder, augments the relative risk ratio of violence, especially in combination with substance use disorder. Few studies of these correlates of violence and especially homicide have been reported in low- and medium-income countries (LMIC). Using the structured clinical interview for DSM diagnosis (SCID), personality disorders were identified in a cross sectional study involving 546 homicide offenders in Jimma prison, Ethiopia. Predictors of personality disorder were determined using multivariate analysis of various demographic and clinical variables, for example, age, psychiatric history and substance use. Out of the 316 offenders who completed the SCID, only 16% fulfilled DSM IV criteria for personality disorder. The rationale for killing, self-defence, anger and revenge (52% of offenders), planning involved in offending (50%) and reasonably high level of relationship functioning (57% married) were different from most data from the high-income countries. Diagnostically relevant cultural factors in LMIC, not in play in high-income countries, may explain the differences in personality disorders similar to other mental disorders and the underlying mediators of homicide.

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

    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.

    Despite the recent effort by Chan and Frei in studying female sexual homicide offenders (SHOs), much is still unknown about this underresearched offender population. One largely unexplored area is how female SHOs of different races commit their killings. Using FBI Supplemental Homicide Reports (SHR) data (1976-2007), 105 White and 94 Black female SHOs (N=204) were examined for their differential offending patterns. Most female SHOs, regardless of race, killed victims of the opposite gender (i.e., heterosexual offenses). Most frequently targeted by female SHOs of both races (44% of Whites and 57% of Blacks) were known victims (e.g., friends, acquaintances) who were not intimate partners or family members. Firearms were the most common weapons used by female SHOs (60% of Whites and 48% of Blacks). The second most common weapon type used by Black offenders was an edged weapon (32%), whereas for White offenders it was a personal weapon (17%). Black female SHOs normally perpetrated their offense in large cities (69%), while White female SHOs most often committed their crime in suburban areas (40%). This study underscores importance of considering the offender racial group in female sexual murder investigations. Hence, several implications for offender profiling are offered.

  1. Reducing homicide risk in Indianapolis between 1997 and 2000.

    2010-09-01

    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

  2. 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

  3. The influence of several changes in atmospheric states over semi-arid areas on the incidence of mental health disorders

    The incidence of suicide attempts [Deliberate Self Harm (DSH); ICD-10: X60-X84] and psychotic attacks (PsA; ICD-10, F20-F29) in association with atmospheric states, typical for areas close to big deserts, was analyzed. A retrospective study is based on the 4,325 cases of DSH and PsA registered in the Mental Health Center (MHC) of Ben-Gurion University (Be'er-Sheva, Israel) during 2001-2003. Pearson and Spearman test correlations were used; the statistical significance was tested at p < 0.1. The influence of temperature and humidity on suicide attempts ( N SU ) and psychotic attacks ( N PS ) was weakly pronounced ( p > 0.1). Correlation coefficients between N SU and N PS and speed WS of westerly wind reaches 0.3 ( p < 0.05), while their dependence on easterly WS was weaker ( p > 0.09). Variations in easterly wind direction WD influence N SU and N PS values ( p < 0.04), but no corresponding correlation with westerly winds was found ( p > 0.3). Obviously ,in transition areas located between different regions ,the main role of air streams in meteorological-biological impact can scarcely be exaggerated. An unstable balance in the internal state of a weather-sensitive person is disturbed when the atmospheric state is changed by specific desert winds, which can provoke significant perturbations in meteorological parameters. Results indicate the importance of wind direction, defining mainly the atmospheric situation in semi-arid areas: changes in direction of the easterly wind influence N SU and N PS , while changes in WS are important for mental health under westerly air streams. Obviously, N SU and N PS are more affected by the disturbance of weather from its normal state, for a given season, to which the local population is accustomed, than by absolute values of meteorological parameters.

    It has been well demonstrated the relationship between the infection with high-risk human papillomavirus (HPVs) genotypes and cervical cancer. In Northeastern Argentina a high incidence of this pathology has been described and therefore a high prevalence of HPV infection is expected. In order to identify HPV genotypes associated with malignant and pre-malignant cervical lesions present in the area, 53 ecto-endo cervical cell specimens obtained from women with cytohistological alterations were studied by a PCR-RFLP technique. Out of 53 patients, 34 (64.2%) were positive for HPV infection, being HPV-16 (32.3%) the most frequently found genotype, followed by HPV-58 (14.7%), -6, -18 and -45 (5.9%), -33, -52, -53, -54, -56, -66, -MM4 and -LVX100 (2.9%). Also 5 cases of infection caused by multiple genotypes were found, which corresponded to 14.7% of the positive cases. Results indicate that besides HPV-16 and -18, the most prevalent high-risk HPV genotypes worldwide, others like -45 and -58 as well as co-infection cases are frequent between women of Northeastern Argentina, and a particular attention should be paid to this circumstance because it could be an epidemiological feature of regional importance and a useful information for a future vaccination program.

    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

    An analysis of suicide and homicide rates was made for countries of the Eastern Mediterranean Region using global burden disease data for 2000. The suicide/homicide ratio by age, sex and country level of income was calculated by dividing the suicide rate by the sum of the suicide and homicide rate. Males were more often victims of homicide whilst females were more often victims of suicide. For all male age groups except males 60+ years in high-income countries, the suicide/homicide ratio was 50% or less while for all female age groups except those 60+ years in high-income countries and females 5-14 years old in low- and middle-income countries, the suicide/homicide ratio was over 50%.

    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.

    The objective of the current paper is to report a new case of sexual murder involving human arson and summarize the literature on the phenomenon of sexual homicide. The present case study is unprecedented in Greece and a rarity in international literature due to the fact that the victim suffered genital mutilation and incineration while still alive. The evaluation consisted of 176 articles; 53 were reviewed by the authors. The results revealed sparse, but significant, research findings. The authors discuss the limitations regarding research, incidence of the phenomenon, crime-scene patterns, offender characteristics (killing methods, motive inferences, sociodemographic data, classifications, psychopathology, modus operandi), and victim selection. The incidence of the phenomenon is unclear (1-4%) due to non-standardized criteria. It is an expression of displaced anger or sexual sadism and/or a way to elude detection (ancillary benefit). Most offenders (in their first kill) and victims were in their late 20s to early 30s and belong to Caucasian populations. Personal weapons were commonly used against women, strangulation is the prevalent killing method against children, and firearms against men. Most of the sexual homicide perpetrators are non-psychotic at the time of the attack, but experience personality pathology, primitive defenses, pathological object relations, and withdrawal into fantasy in order to deal with social isolation.

    Effective federal regulation of firearm dealers has proven difficult. Consequently, many states choose to implement their own regulations. We examined the impact of state-required licensing, record keeping of sales, allowable inspections, and mandatory theft reporting on firearm homicide from 1995 to 2010. We found that lower homicide rates were associated with states that required licensing and inspections. We concluded that firearm dealer regulations might be an effective harm reduction strategy for firearm homicide.

    We examined 169 deceased persons and 76 homicide-suicide cases reported in Japan's Kanagawa Prefecture from 1999 to 2011. The relationships between homicide-suicide perpetrators and homicide victims; the numbers of victims; their age, sex, causes and places of death; motivation; and the presence or absence of a suicide note were extracted and examined. The relationship between homicide-suicide perpetrators and homicide victims was examined based on findings from the following: 24 married couples (31%), 22 parents and children aged ≥18 years (29%), 19 parents and children aged ≤17 years (25%), seven families (9%), two couples (3%) and two miscellaneous relationships (3%). The perpetrators comprised 39 men and 40 women, with a mean age of 51.6 years. The victims comprised 39 men and 51 women, with a mean age of 35.4 years. In our study, approximately half of the perpetrators were female, which differed greatly from the reports from Western countries, where most perpetrators were male. Homicide-suicides among married couples accounted for a higher proportion of overall homicide-suicide deaths in Western countries. In Japan, homicide-suicide occurred more frequently with parents and children. Cases in which a mother committed suicide after having killed her young children accounted for a high proportion of these deaths. Because these events occur so frequently in Japan, we recommend making particular efforts to reduce homicide-suicides among mothers and children.

    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.

    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.

    This commentary addresses the high homicide rates among young Black men in Toronto, Ontario. It posits that homicide among this population is an unrecognized major public health crisis that should be a priority for the field. The author suggests that the dramatic rate of Black homicides in Toronto is a consequence of income inequality, poverty, poor quality of life, mental health risks, and sustained racism. The commentary calls upon public health scientists to prioritize research about violence and homicide among young Black men in Toronto. It suggests that current and future policy making would be better served by their enquiries into the nature and causes of the persisting dilemma.

    Minor physical anomalies may be external markers of abnormal brain development, so the more common appearance of these signs in homicidal schizophrenia might suggest the possibility of a more seriously aberrant neurodevelopment in this subgroup. The aim of the present study was to investigate the rate and topological profile of minor physical anomalies in patients with schizophrenia with the history of committed or attempted homicide comparing them to patients with schizophrenia without homicide in their history and to normal control subjects. Using a list of 57 minor physical anomalies, 44 patients with the diagnosis of schizophrenia were examined with the history of committed or attempted homicide, as a comparison 22 patients with the diagnosis of schizophrenia without the history of any kind of homicide and violence and 21 normal control subjects were examined. Minor physical anomalies are more common in homicidal schizophrenia patients compared to non-homicidal schizophrenia patients and normal controls, which could support a stronger neurodevelopmental component of etiology in this subgroup of schizophrenia. The higher rate of minor physical anomalies found predominantly in the head and mouth regions in homicidal schizophrenia patients might suggest the possibility of a more seriously aberrant brain development in the case of homicidal schizophrenia.

    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 study represents a completely new criminological phenomenon among homicide offenses: the killing of many very old terminally or incurably ill patients in hospitals and sometimes nursing homes. These homicides are a worldwide phenomenon. Six distinguishing indications of this phenomenon are differentiated from the traditional homicide criminology. Some statistical data of 11 nurses are presented, sentenced between 1976 and 1993 in the Federal Republic of Germany, Austria, Norway, the Netherlands, and in the United States of America. Centerpiece of this description is the differentiation of ten important characteristics of these homicidal acts. It is not possible to discuss the motives of this crime in detail.

    The purpose of the study is to examine non-fatal strangulation by an intimate partner as a risk factor for major assault, or attempted or completed homicide of women. A case control design was used to describe non-fatal strangulation among complete homicides and attempted homicides (n =506) and abused controls (n = 427). Interviews of proxy respondents and survivors of attempted homicides were compared with data from abused controls. Data were derived using the Danger Assessment. Non-fatal strangulation was reported in 10% of abused controls, 45% of attempted homicides and 43% of homicides. Prior non-fatal strangulation was associated with greater than six-fold odds (OR 6.70, 95% CI 3.91–11.49) of becoming an attempted homicide, and over seven-fold odds (OR 7.48, 95% CI 4.53–12.35) of becoming a completed homicide. These results show non-fatal strangulation as an important risk factor for homicide of women, underscoring the need to screen for non-fatal strangulation when assessing abused women in emergency department settings.

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

    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 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

    One hundred samples of dried fruits (20 dried raisins, 20 walnuts, 20 peanuts, 20 dried figs and 20 pistachios) and 20 samples of rice purchased from retail shops in the Rabat and Salé area in Morocco were analysed for ochratoxin A (OTA) by immunoaffinity clean-up (IAC) and liquid chromatography (LC) with fluorescence detection. The limit of quantification (LOQ) (S/N = 10:1) of OTA was 0.02 ng g(-1) in rice, 0.03 ng g(-1) in pistachio, peanut and walnut, and 0.03 ng g(-1) in dried raisins and dried figs. The incidences of occurrence of OTA in dried raisins, walnuts, peanuts, dried figs and rice were 30, 35, 25, 65 and 90%, respectively. Analytical results showed that pistachio samples contained no detectable OTA, but concentrations ranged from 0.02 +/- 0.01 to 32.4 +/- 2.10 ng g(-1) in rice, from 0.10 +/- 0.05 to 2.36 +/- 0.75 in peanut, from 0.03 +/- 0.01 to 1.42 +/- 0.45 in dried figs, from 0.05 +/- 0.02 to 4.95 +/- 0.02 in dried raisins, and from 0.04 +/- 0.01 to 0.23 +/- 0.05 in walnuts. The results also showed that 15% of the total number of rice samples analysed exceeded the 2002 regulatory limit set by European Union regulations for cereals. This is the first report on the occurrence of OTA in dried fruits and rice available in Morocco.

    Esophageal carcinoma is characterized by a widely ranged incidence variation among the different geographic regions. Anyang is a county in Henan Province of North China with the highest prevalence of esophageal carcinoma. Human papillomavirus (HPV) infection has been linked to the etiology of esophageal cancer in this area. In this study, we investigated correlations of the polymorphisms at low molecular weight polypeptide (LMP) and transporters with antigen processing (TAP) genes, with the risk of esophageal carcinoma. DNA extracted from either tumor specimens or esophageal epithelial cells was used to test HPV infection. Peripheral blood lymphocyte DNA was used for LMP/TAP genotyping. Polymerase chain reaction was performed to analyze HPV infection and LMP/TAP gene polymorphisms. The combined effect of LMP/TAP gene polymorphisms and HPV infection on esophageal carcinoma was analyzed by using unconditional logistic regression models. The TAP2 codons 379 isoleucine carriers and LMP7 codons 145 lysine carriers were found to be more susceptible to esophageal carcinoma (OR = 2.74, 95% CI = 1.15-6.49, P = 0.023 for TAP2; OR = 2.19, 95% CI = 1.09-4.37, P = 0.027 for LMP7). Patients carrying homozygous LMP7/TAP2 haplotype C, which contained the glutamine at LMP7 codons 145 and the isoleucine at TAP2 codons 379, were more prone to develop esophageal carcinoma (OR = 2.96, 95% CI = 1.13-7.81, P = 0.027). An additive effect on the risk of esophageal carcinoma development was found among individuals carrying LMP7/TAP2 haplotype C and infected by HPV (OR = 4.33, 95% CI = 2.53-7.42, P < 0.0001). LMP7/TAP2 haplotype C may act as the risk factor in esophageal carcinoma development and it may influence the tumorigenesis in HPV infected individuals.

  3. Social Structure, Anomie, and National Levels of Homicide.

    Merton's "Social Structure and Anomie" seeks to explain how "socio-cultural" influences exert "definite pressures" to engage in non-conformity. Despite having a significant influence, few studies have assessed the degree to which Merton's propositions explain cross-national variation in levels of crime. Using data on national levels of homicide, data from the World Values Survey, and other structural controls, the present study assesses the degree to which deinstitutionalization, demoralization, and blocked opportunity interact to explain crime cross-nationally. Results provide a high degree of support for Merton's assertion that societal types characterized by relatively high levels of materialism and/or demoralization or deinstitutionalization suffer from higher levels of homicide. However, there is less support for Merton's assertion that inequality interacts with various societal patterns of means/ends integration in a meaningful way. Findings and implications for the utility of classical anomie as a general macro-level theory are discussed.

    Toilet paper is a ubiquitous personal hygiene product that is usually considered harmless. It was reported however to have been used as a mean of self-destruction in two unusual suicides, and is here reported to have been used to commit homicide. The body of a 91-year-old woman suffering from Alzheimer's disease was found in the bedroom of her nursing home, a roll of toilet paper near the body and toilet paper protruding from the mouth. At autopsy, pellets of toilet paper were impacted in the buccal cavity and the laryngopharynx above the epiglottis. The cause of death was established as smothering on toilet paper, whereas the manner of death was ruled as homicidal. Non-lethal blunt head injuries were considered to be a contributive factor, by lowering the victim's resistance. The perpetrator was another elderly woman, also suffering from Alzheimer's disease.

  5. Applying the Principles of Homicide by Heart Attack.

    Homicide by heart attack is a well-established model in forensic pathology that describes death elicited during or immediately after a criminal act where a threat or fear of physical injury is present. After its introduction nearly 4 decades ago, the principle has undergone a handful of modifications but still maintains its core concepts. All cases of this nature during a 20-year period at the Wayne County Medical Examiner's Office were compared and contrasted for demographics, circumstances and scene investigation, and autopsy and toxicology findings. Of the cases fulfilling the previously established criteria for homicide by heart attack, more than 80% displayed significant changes because of hypertension. This finding coincides with the high prevalence of hypertension in our urban population and highlights the significance of this disease. Also present were minor external and internal injuries in select cases, which reinforce the understanding that physical contact between the decedent and assailant does not preclude this diagnosis.

    Aims and method To explore the portrayal of homicide-suicide in newspaper articles, particularly how mental illness was reported. We carried out a qualitative study in England and Wales (2006-2008). Data from newspaper articles obtained via the LexisNexis database were used to examine a consecutive series of 60 cases. Results A fascination with extreme violence, vulnerable victims and having someone to blame made homicide-suicides newsworthy. Some offenders were portrayed in a stereotypical manner and pejorative language was used to describe mental illness. The findings showed evidence of inaccurate and speculative reference to mental disorder in newspaper reports. Clinical implications The media should avoid speculation on people's mental state. Accurate reporting is essential to reduce stigma of mental illness, which may in turn encourage people to seek help if they experience similar emotional distress. PMID:26755983

    The aim of this study is to investigate epidemiological characteristics of the victims and the offenders in children homicide cases and to propose preventive measures. We retrospectively investigated homicides and deaths by neglect involving children aged 15 or less, which have been autopsied in the Department of Pathology and Legal Medicine of the Raymond Poincaré Hospital, Garches, France, during the 18-year period from 1991 to 2008. Cases included were analyzed for victims' age and gender, victim-assailant's relation, death cause and scenery, and offender's motivation. For the purposes of the study, victims were divided into four age groups: new born; infants (1-23 months); young children (2-5 years); and children (6-15 years). During the study period, 70 victims of homicide or fatal neglect were identified, which equates to a child homicide prevalence of 0.56 per 100,000 children per year. Slightly more than half of the victims (51.4%) were less than 1 year old. Neonaticide prevalence was 0.12 per 100,000 births with an equal distribution between genders. Neonates were most likely to be killed by their mothers while fathers were the most frequent assailants in both infants and children groups. Stepparents were involved in only one case. Familicide cases where children and spouses are killed were perpetrated only by fathers. The leading cause of death was blunt trauma (especially head trauma). In the neonaticide group, half of the victims died from passive neglect whereas gunshots were predominant in the children groups.

    The Colombian city of Medellin has faced a severe problem of violence and homicide. The goal of this retrospective, descriptive-analytical study was to assess the magnitude, distribution, most salient characteristics and possible explanations for the problem between 1980 and 2007. Data were obtained from official databases, hospital records and the available literature, and a focus group was set up. There was a dramatic rise in homicides in the city in the time interval studied, with a total of 84,863 documented murders. Ninety-three percent of the victims were male. The 20 to 29 year-old age group was the most affected. Males in this age group, during the worst year of the period (1991), registered an astounding murder rate of 1,709 per 100,000. Even males in the 15 to 19 year age group and the older brackets saw high murder rates. The most common victims were from the lower and lower-middle socioeconomic strata, as has been observed elsewhere in the region. Serious problems were identified in information and in the provision of services. The impact of homicide on the delivery of healthcare services is discussed and a series of tasks for the healthcare sector in the control of this type of violence is proposed.

    Background Human cysticercosis is a zoonotic disease causing severe health disorders and even death. While prevalence data become available worldwide, incidence rate and cumulative incidence figures are lacking, which limits the understanding of the Taenia solium epidemiology. Methodology/Principal findings A seroepidemiological cohort study was conducted in a south-Ecuadorian community to estimate the incidence rate of infection with and the incidence rate of exposure to T. solium based on antigen and antibody detections, respectively. The incidence rate of infection was 333.6 per 100,000 person-years (95% CI: [8.4–1,858] per 100,000 person-years) contrasting with a higher incidence rate of exposure 13,370 per 100,000 person-years (95% CI: [8,730–19,591] per 100,000 person-years). The proportion of infected individuals remained low and stable during the whole study year while more than 25% of the population showed at least one antibody seroconversion/seroreversion during the same time period. Conclusions/Significance Understanding the transmission of T. solium is essential to develop ad hoc cost-effective prevention and control programs. The estimates generated here may now be incorporated in epidemiological models to simulate the temporal transmission of the parasite and the effects of control interventions on its life cycle. These estimates are also of high importance to assess the disease burden since incidence data are needed to make regional and global projections of morbidity and mortality related to cysticercosis.

    Objective We examined the extent of changes in absolute and relative geographic disparities in six colorectal cancer (CRC) indicators using data about persons aged 50 and older from 195 counties in the 1988–2006 Surveillance, Epidemiology, and End Results Program database. Methods County-level trends in six colorectal cancer indicators (overall CRC incidence, descending colon cancer incidence, proximal colon cancer incidence, late-stage CRC incidence, CRC mortality, and 5-year probability of CRC death) were summarized using the estimated annual percentage change. Observed county rates were smoothed using Bayesian hierarchical spatiotemporal methods to calculate measures of absolute and relative geographic disparity and their changes over time. Results During the study period, absolute disparity for all six indicators decreased (CRC incidence: 43.2%; proximal colon cancer: 31.9%; descending colon cancer: 52.8%; late-stage CRC: 50.0%; CRC mortality: 57.8%; 5-year CRC-specific probability of death: 12.2%). Relative disparity remained stable for all six indicators over the entire study period. Conclusion Important progress has been made toward achieving the Healthy People 2010 and NCI strategic objectives for reducing geographic disparities, although absolute and relative disparities remain in CRC.

    The levels of streptococcal antibody titers in populations with or without rheumatic fever from an area with a relatively high incidence of rheumatic fever and an area with a low incidence of this disease were compared. Streptococcal antibody titers were determined for two populations, each of which included children without rheumatic fever (nonrheumatic children) and rheumatic fever patients. The two populations were derived from two separate geographic areas, one with a high incidence of rheumatic fever (Grenada) and another with a low incidence of this disease (central Florida). The results revealed an absence of consistent differences in the geometric mean antibody titers between the nonrheumatic subjects and the rheumatic fever patients from Grenada. In the population from Grenada, the mean anti-streptolysin O and anti-DNase B titers were higher in the nonrheumatic controls (P of 0.085 and 0.029, respectively). However, the mean titer of the antibody to the group A streptococcal cell wall carbohydrate was higher in the rheumatic fever patients than in the nonrheumatic controls (P = 0.047). This finding contrasted with the finding that the means of all three streptococcal antibody titers in the patients with rheumatic fever were significantly higher than those in the nonrheumatic subjects from Florida (P = 0.01-<0.001). The reason for this paradoxical finding became evident when the streptococcal antibody titers of the nonrheumatic subjects from Grenada and Florida were compared, revealing significantly higher levels of all three antibodies in the nonrheumatic subjects from Grenada than in the nonrheumatic subjects from Florida (P < 0.001). These results suggest that nonrheumatic individuals in an area with a high incidence of rheumatic fever have inordinately elevated levels of streptococcal antibodies in serum. The presence of elevated streptococcal antibody titers in such a population, which probably reflects a high background prevalence of streptococcal

    Healthcare inequalities for black and minority ethnic (BME) patients in forensic mental health services in the UK are stark. Despite the level of attention given to this over the last 15 years there has been little progress to address disparities. There is a great deal of confusion over what is understood by culture, and what aspects of culture signal specific needs of BME patients. In addition, we have a lack of empirical research demonstrating what it means for psychiatrists to be culturally competent. These are all important barriers against progress in this area. Using a homicide case study that illustrates the typical issues encountered in practice, we explore how to use a cultural formulation in order to assess the role of culture within a forensic psychiatry setting. Finally, practical advice is offered to assist expert witnesses in preparing court reports that adequately consider the significance of defendants' cultural beliefs and practices.

    2012-12-01

    This study seeks to analyze the trend of homicide rates (total and by firearm) in Mexico between 1990 and 2009 and identify the variables that best explain the geographical variations of these rates in the 2008-2009 two-year period. Homicide rates, adjusted for age, were calculated for both sexes between 1990 and 2009 and for each state in 2008-2009. Factors associated with the interstate variations in the homicide rates were identified using multiple linear regression analysis. Results show that the homicide rate in Mexico decreased between 1990 and 2007, but doubled over the last two years (from 7.6 to 16.6 per 100,000). In 2009, the male homicide rate was almost 9 times higher than the female rate and about two-thirds of homicides involved firearms. Multivariate analysis reveals that impunity, drug trafficking, alcohol and drug consumption and school dropout in basic education - in that order - are key factors for understanding the geographical variations in homicide rates in Mexico in 2008-2009. Findings suggest that to reduce the number of homicide victims and spatial variations in the rate, it is necessary not only to fight the drug cartels, but above all to implement structural reforms in the criminal justice system and reduce the socioeconomic disparities among states.

  7. Homicide rates among persons aged 10-24 years - United States, 1981-2010.

    PubMed

    2013-07-12

    Homicide disproportionately affects persons aged 10-24 years in the United States and consistently ranks in the top three leading causes of death in this age group, resulting in approximately 4,800 deaths and an estimated $9 billion in lost productivity and medical costs in 2010. To investigate trends in homicide among persons aged 10-24 years for the period 1981-2010, CDC analyzed National Vital Statistics System data on deaths caused by homicide of persons in this age group and examined trends by sex, age, race/ethnicity, and mechanism of injury. This report describes the results of that analysis, which indicated that homicide rates varied substantially during the study period, with a sharp rise from 1985 to 1993 followed by a decline that has slowed since 1999. During the period 2000-2010, rates declined for all groups, although the decline was significantly slower for males compared with females and for blacks compared with Hispanics and persons of other racial/ethnic groups. By mechanism of injury, the decline for firearm homicides from 2000 to 2010 was significantly slower than for nonfirearm homicides. The homicide rate among persons aged 10-24 years in 2010 was 7.5 per 100,000, the lowest in the 30-year study period. Primary prevention strategies remain critical, particularly among groups at increased risk for homicide.

    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)

    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.

  12. The case of Jeffrey Dahmer: sexual serial homicide from a neuropsychiatric developmental perspective.

    2002-11-01

    Sexual serial homicidal behavior has received considerable attention during the last three decades. Substantial progress has been made in the development of methods aimed at identifying and apprehending individuals who exhibit these behaviors. In spite of these advances, the origins of sexual serial killing behavior remain for the most part unknown. In this article we propose a biopsychosocial psychiatric model for understanding the origins of sexual serial homicidal behavior from both neuropsychiatric and developmental perspectives, using the case of convicted serial killer Jeffrey Dahmer as the focal point. We propose that his homicidal behavior was intrinsically associated with autistic spectrum psychopathology, specifically Asperger's disorder. The relationship of Asperger's disorder to other psychopathology and to his homicidal behavior is explored. We discuss potential implications of the proposed model for the future study of the causes of sexual serial homicidal crime.

    The incidence of Legionnaires' disease has an uneven geographical distribution in Denmark, ranging from 3 to 70 notified cases per million inhabitants per year in different towns. We investigated the prevalence of antibodies to Legionella in the one town with a consistently high incidence (Randers, Aarhus County) and compared it with that of an area of average incidence (Vejle, Vejle County). Blood samples were collected from healthy blood donors in Randers (n=308) and in Vejle (n=400), and analysed for antibodies to Legionella by indirect immunofluorescence antibody test with L. pneumophila, L. micdadei, and L. bozemanii as antigens. Overall 22.9% of the donors had antibody titres of > or = 1:128; indicating that antibodies to Legionella are common in healthy individuals, and reflecting that the bacteria may be widely distributed in the environment. Surprisingly, the study did not reveal a higher prevalence in the hyperendemic area. Thus, the high incidence of notified cases in this particular town may not be attributed to an overall increased exposure of the general population.

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

    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.

    The Defense Threat Reduction Agency (DTRA) commissioned an assessment of the Consequence Management (CM) plans in place on military bases for response to a chemical attack. The effectiveness of the CM plans for recovering from chemical incidents was modeled using a multiple Decision Support Tools (DSTs). First, a scenario was developed based on an aerial dispersion of a chemical agent over a wide-area of land. The extent of contamination was modeled with the Hazard Prediction and Assessment Capability (HPAC) tool. Subsequently, the Analyzer for Wide Area Restoration Effectiveness (AWARE) tool was used to estimate the cost and time demands for remediation based on input of contamination maps, sampling and decontamination resources, strategies, rates and costs. The sampling strategies incorporated in the calculation were designed using the Visual Sample Plan (VSP) tool. Based on a gaps assessment and the DST remediation analysis, an Enhanced Chemical Incident Response Plan (ECIRP) was developed.

    Arrow wounds represent an unusual class of wounds rarely seen by most forensic pathologists. In this paper we present a case of homicide by bow and arrow and the characteristics of such injuries. The essential characteristics of the lesions obtained from conically-tapered field points and from hunting broadhead tips are described and discussed in relation to injuries caused by firearm bullets. In the present case, three arrows struck the victim, and the order in which the injuries were sustained are analyzed. We also discuss the possibilities of localizing the shooter relative to the victim by analysis of the trajectories.

    It has been estimated that five million snake bite cases occur worldwide every year, causing about 100,000 deaths. Snake bite is exclusively accidental in nature. Suicide by snake bite is very rare and homicidal snake bite is not reported. In the present case, a contract killer was hired, who used a poisonous snake to kill an elderly couple by way of direct snake bite. We believe this to be the first case reported where a snake was directly used for the murder of two victims through a contract killer.

  1. Is environmental radon gas associated with the incidence of neurodegenerative conditions? A retrospective study of multiple sclerosis in radon affected areas in England and Wales.

    2016-04-01

    To test whether an association exists between radon gas concentration in the home and increased multiple sclerosis (MS) incidence, a retrospective study was undertaken of MS incidence in known areas of raised domestic radon concentration in England and Wales, using The Health Improvement Network (THIN) clinical research database. The study population comprised 20,140,498 person-years of clinical monitoring (males: 10,056,628: 49.93%; females: 10,083,870: 50.07%), representing a mean annual population of 2.5 million individuals. To allow for the possible latency of MS initiation following exposure, data extraction was limited to patients with at least five years registration history with the same GP practice before first diagnosis. Patient records were allocated to one of nine radon concentration bands depending on the average radon level in their postcode sector. MS incidence was analysed by searching for patients with first MS diagnosis over the eight calendar years 2005-2012 inclusive. 1512 new MS cases were diagnosed, 1070 females, 442 males, equivalent to raw incidence rates of 7.51, 10.61 and 4.40 per 10(5) person-years respectively, comparable to previously reported results. Of these new cases, 115 could be allocated to one of the radon bands representing high radon areas. Standardising to the UK 2010 population, excess relative risk (ERR) figures for MS were calculated for each radon band. Linear regression of ERR against mean band radon concentration shows a positive gradient of 0.22 per 100 Bq·m(-3) (R(2) = 0.25, p = 0.0961) when forced through the origin to represent a linear-no-threshold response. The null hypothesis falls inside the 95% confidence interval for the linear fit and therefore this fit is not statistically significant. We conclude that, despite THIN sampling around 5% of the population, insufficient data was available to confirm or refute the hypothesised association between MS incidence and radon concentration.

    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

    The present study examined the prevalence, demographic distribution, and mental health correlates of losing a loved one to homicide. A national sample of 1,753 young adults completed structured telephone interviews measuring violence exposure, mental health diagnoses, and loss of a family member or close friend to a drunk driving accident (vehicular homicide) or murder (criminal homicide). The prevalence of homicide survivorship was 15%. African Americans were more highly represented among criminal homicide survivors. Logistic regression analyses found that homicide survivors were at risk for past year posttraumatic stress disorder (OR = 1.88), major depressive episode (OR = 1.64), and drug abuse/dependence (OR = 1.77). These findings highlight the significant mental health needs of homicide survivors.

    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.

    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.

  6. Diarrhea incidence and intestinal infections among rotavirus vaccinated infants from a poor area in Brazil: a spatial analysis

    PubMed Central

    2014-01-01

    Background Acute diarrhea is the second leading cause of mortality among children under 5 years of age in developing countries. The pathogen most strongly associated with diarrhea is rotavirus followed by enteric pathogens such as bacteria, helminthes and protozoan. Adequate sanitation and water supply contribute to decrease acute diarrhea incidence of most etiologic agents, although vaccination remains the most important intervention to control rotavirus acute diarrhea. This study aimed to describe environmental conditions and analyze spatially the acute diarrhea and intestinal infection among rotavirus vaccinated infants from Laranjeiras-Sergipe, Brazil. Methods Children were enrolled between 2 and 11 months of age and followed through 12 months. Demographic, socioeconomic and environmental data were obtained from a questionnaire, and immunization data were obtained from children vaccination card. Children stool samples were collected each month in order to run laboratory analyses. The household spatial localization was obtained by using a Global Positioning System (GPS). Spatial analysis was performed using the TerraView computer program and Kernel intensity estimation. Results A total of 1,113 stool samples were collected with 80 being diarrhea associated. Diarrhea incidence rate was 0.5 ± 1.0 episodes/child/year. The overall infection rates by Ascaris lumbricoides, Endolimax nana, Giardia lamblia and rotavirus were 5.1%, 3.0%, 0.9% and 2.6%, respectively. 3.8% of diarrhea-associated stool samples were positive for rotavirus and 11.3% were positive for helminths and protozoans. There were some changes on spatial distribution of intestinal infections and diarrhea episodes along the four trimesters evaluated. Conclusions The studied infants live equally in precarious conditions of sanitation which probably explain the significant rates of parasitic infections appearing in early life. The low acute diarrhea incidence in the studied rotavirus vaccinated

    2011-02-28

    In England and Wales, a lifetime history of mental disorder is recorded in almost a third of homicides but mental illness as a defence in homicide cases has recently come under review. In this study, we aimed to compare the social, criminological and clinical characteristics of women and men convicted of homicide and secondly, to understand how pathways through the judicial system differ by gender of the perpetrator, characteristics of the offence and mental illness. A cross sectional study of 4572 convicted homicide perpetrators in England and Wales 1997-2004 was performed. Significantly more women who had committed homicide had a lifetime history of mental illness and were more likely to be mentally ill at the time of offence compared to men. Women more often received non-custodial sentences, whether or not they had mental illness. If the victim were a child or other relative, the courts were more lenient with women. Gender and the presence of mental illness both influence the characteristics of homicide and outcome of the legal process in the UK. Our findings suggest that all perpetrators of homicide should have a psychiatric assessment pre-trial. Psychiatrists need to rate risk objectively in a gender blind way when providing psychiatric reports to be used as evidence in court.

    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.

    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.

    2007-01-01

    Establishing behavioral consistency in serial homicide offending behavior is essential when linking homicides together and to a common offender. An examination of 35 serial homicide behaviors utilized by 90 offenders in 450 serial homicide cases was carried out to identify whether these offenders consistently performed the same behaviors across their series of homicides and whether it is more effective to examine individual behaviors or groupings of behaviors in order to identify behavioral consistency. This study provides the first empirically based evidence testing the use of using single behaviors as linking factors in linking homicide cases in a series, and shows that this method has inherent difficulties in accomplishing this, thus providing the first wave of empirical testing that questions current theories in the literature on serial homicide, which has suggested that signatures or specific key behaviors are important in understanding the consistency in an offender's behavior across the crimes. Recommendations for future studies on linking using signatures are suggested, including a more in-depth qualitative empirical evaluation of individual series.

    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.

    ABSTRACT Aim To synthesize the results of marijuana, cocaine and opiate drug toxicology studies of homicide victims and examine variation in results across person and setting characteristics. Methods A meta-analysis of 18 independent studies identified from an extensive review of 239 published articles that met the inclusion criteria of reporting marijuana, cocaine and/or opiate toxicology test results for homicide victims. A total of 28 868 toxicology test results derived from 30 482 homicide victims across five countries were examined. Results On average, 6% of homicide victims tested positive for marijuana, 11% tested positive for cocaine, and 5% tested positive for opiates. The proportion of homicide victims testing positive for illicit drugs has increased over time. Age had a strong curvilinear relationship with toxicology test results, but gender differences were not apparent. Hispanic and African American homicide victims were more likely to test positive for cocaine; Caucasians were most likely to test positive for opiates. Cocaine use appeared to be related to increased risk of death from a firearm and was a greater risk factor for violent victimization in the United States than in Newfoundland and Scandinavia. Conclusion There are relatively few studies of illicit drug toxicology reports from homicide victims that allow for cross-cultural comparisons. This study provides a basis for comparing future local toxicology test results to estimates from existing research.

  13. Homicide by fright: the intersection of cardiology and criminal law.

    2010-01-01

    The prevailing lay wisdom associates emotional stress with sudden death, and recent medical reports have linked massive catecholamine surges with demonstrable cardiac dysfunction that can be either reversible or fatal. This association does not strictly prove causality, and the question remains open for additional scientific investigation. From the legal viewpoint, however, the issue has been resolved, and case law clearly holds that sudden emotional stress can cause death. More significantly, case law also holds that if the sudden emotional stress is caused by criminal conduct, the resulting death of a victim of the criminal conduct can be prosecuted as homicide. Cardiologists are often called to testify in such circumstances. In the present study, we have reviewed 8 legal cases that are the basis of current opinions in these matters. These legal principles can be summarized as follows: emotional stress is sufficient, and physical abuse is not required for conviction; a time-lapse between the induction of emotional stress and death does not necessarily mitigate the charge of homicide; the criminal act must be the proximate cause of the victim's death; however, the accused does not always need to be physically present to commit the crime. In conclusion, although the pathophysiology of sudden death associated with massive emotional stress has not been fully elucidated from a scientific viewpoint, in the legal system, the association can be causative and can be the basis for a criminal prosecution. Cardiologists may be called on to provide expert opinions in the prosecution of these cases.

    AIM: To investigate the relationship between different sources of drinking water supply, water quality improvement and gastric cancer mortality rate in a high risk area. METHODS: A retrospective-cohort survey was carried out in all towns of this county to study the effect of different sources of drinking water supply and water quality improvement on gastric cancer mortality rate. RESULTS: The gastric cancer mortality rate among the population 124.05/105 drinking river water was obviously higher than that of drinking shallow well water (74.85/105) (P < 0.01) according to the Zhanggang Town 16 years accumulated data. The same pattern was presented in 7 towns after balancing the confounders. The gastric cancer mortality rate of population drinking river water was 86.03/105, which was higher than those drinking shallow well water (62.03/105) and tap water (29.78/105) (P < 0.01). When the drinking water switched from river and well water to tap water, the gastric cancer incidence decreased to 30.33/105 and 26.10/105, and the gastric cancer mortality decreased by 59% and 57% respectively. CONCLUSION: The quality of drinking water is one of the important factors of increased incidence of gastric cancer in Changle County, and water quality improvement has a beneficial effect, but the cause of high gastric cancer incidence may be multi-factorial in this area.

    To investigate the possible association of P53 codon 72 Arg/Pro polymorphisms with risk of gastric cancer in the high incidence Hexi area of Gansu province in China. Blood samples from 140 patients with gastric carcinoma and 125 healthy controls were collected in Hexi area of Gansu province. Polymorphism of P53Arg72Pro was genotyped by PCR-TaqMan. For detection Helicobacter pylori infection, Warhin-Starry staining was used. Three kinds of polymorphisms of P53Arg72Pro were Arg/Arg, Arg/Pro, Pro/Pro. The frequencies in gastric cancer group were 15.7, 60.0, 24.3%, and the frequencies in healthy controls were 25.6, 54.4, 20.0%, respectively. P53 codon 72 Pro carrier genotype (Arg/Pro+Pro/Pro) increased risk of gastric carcinoma with an odds ratio 1.840 (95% CI: 1.006-3.387). Helicobacter pylori infection rate was 68.6% in patients group and 50.4% in healthy controls. Helicobacter pylori infection rate in gastric cancer patients was remarkably higher than that in the controls (OR: 2.147, 95% CI: 1.302-3.541, P=0.003). Stratification analysis showed that P53 codon 72 Pro carrier genotype with Helicobacter pylori infection was significantly higher in cases than that in the controls (OR: 4.182, 95% CI: 1.850-9.454). P53Arg72Pro polymorphisms could be a risk factor for gastric cancer in high incidence Hexi area of Gansu Province in China. P53 codon 72 Pro carrier genotype and Helicobacter pylori positive infection may have a synergistic effect on gastric cancer in high incidence Hexi area of Gansu Province in China.

    Sharpe, Tanya L; Joe, Sean; Taylor, Katie C

    Suicide and homicide are among the leading causes of death for young African-American men; however, little is known about how family members cope with these types of deaths. This exploratory phenomenological study examines the traumatic loss and coping experiences of a purposive convenience sample of 12 immediate African-American surviving family members with a combined experience of 13 deaths, 8 suicides and 5 homicides. Novel aspects of suicide and homicide survivor phenomenon were identified, including Survivor Responses and Reactions, Coping Strategies, and Survivor Service Needs. The implications for research and for those providing services to surviving African-American families are discussed.

    The current research produces regression models with sample sizes from 127 to 131 by initially employing a data set of 170 nations. The current study finds that ethnic heterogeneity and linguistic heterogeneity lead to higher homicide rates. However, religious heterogeneity has no impact on homicide rates. The present article also tests an interaction effect between population heterogeneity and income inequality. Unlike J. R. Blau and Blau (1982) and Avision and Loring (1986) proposition, the interaction term is not related to national homicide rates. The current study also discusses the theoretical implications of those findings.

    To investigate the possible association of polymorphisms, cyclooxygenase-2 (COX-2) promoter region -899G>C, COX-2 codon 587G>A, with risk of gastric cancer in the high incidence Hexi area of Gansu province in China. Blood samples from 140 patients with gastric carcinoma and 125 normal persons were collected in Hexi area of Gansu province in China. Polymorphisms of COX-2 -899G>A and COX-2 587G>A were genotyped by PCR-TaqMan. For detection Helicobacter pylori infection, Warhin-Starry staining was used. Three kinds of polymorphisms of COX-2 -899G>C were GG, GC and CC. The frequencies in gastric cancer patients were 72.9, 21.4 and 5.7%, and the frequencies in controls were 84.0, 12.8 and 3.2%, respectively. COX-2 -899C carrier (GC + CC) increased risk of gastric carcinoma with an odds ratio 1.950 (95% CI: 1.067-3.586, P=0.029). The genotype of COX-2 587G>A polymorphism were GG, GA and AA. The frequencies in patients group were 86.4, 11.4 and 2.2%, and the frequencies in controls were 89.6, 9.6 and 0.8%, respectively. There was no significant difference between cases and controls in each genotype. Helicobacter pylori infection rate was 68.6% in patients group and 50.4% in healthy controls. Helicobacter pylori infection rate in gastric cancer patients was remarkably higher than that in normal people (OR: 2.147, 95% CI: 1.302-3.541, P=0.003). Stratification analysis was showed that COX-2 -899C carrier genotype with Helicobacter pylori infection was significantly higher in cases than that in healthy controls (OR: 4.000, 95% CI: 1.638-9.770). The polymorphism of COX-2 -899G>C could be a risk factor for gastric cancer in high incidence Hexi area of Gansu Province in China. COX-2 -899C carrier genotype and Helicobacter pylori positive infection may have a synergistic effect on gastric cancer in high incidence Hexi area of Gansu Province in China. However, the polymorphisms of COX-2 587G>A is no association with gastric cancer in the high incidence Hexi area of Gansu Province

    2012-01-01

    Background Residents of geothermal areas are exposed to geothermal emissions and water containing hydrogen sulphide and radon. We aim to study the association of the residence in high temperature geothermal area with the risk of cancer. Methods This is an observational cohort study where the population of a high-temperature geothermal area (35,707 person years) was compared with the population of a cold, non-geothermal area (571,509 person years). The cohort originates from the 1981 National Census. The follow up from 1981 to 2010 was based on record linkage by personal identifier with nation-wide death and cancer registries. Through the registries it was possible to ascertain emigration and vital status and to identify the cancer cases, 95% of which had histological verification. The hazard ratio (HR) and 95% confidence intervals (CI) were estimated in Cox-model, adjusted for age, gender, education and housing. Results Adjusted HR in the high-temperature geothermal area for all cancers was 1.22 (95% CI 1.05 to 1.42) as compared with the cold area. The HR for pancreatic cancer was 2.85 (95% CI 1.39 to 5.86), breast cancer 1.59 (95% CI 1.10 to 2.31), lymphoid and hematopoietic cancer 1.64 (95% CI 1.00 to 2.66), and non-Hodgkins lymphoma 3.25 (95% CI 1.73 to 6.07). The HR for basal cell carcinoma of the skin was 1.61 (95% CI 1.10 to 2.35). The HRs were increased for cancers of the nasal cavities, larynx, lung, prostate, thyroid gland and for soft tissue sarcoma; however the 95% CIs included unity. Conclusions More precise information on chemical and physical exposures are needed to draw firm conclusions from the findings. The significant excess risk of breast cancer, and basal cell carcinoma of the skin, and the suggested excess risk of other radiation-sensitive cancers, calls for measurement of the content of the gas emissions and the hot water, which have been of concern in previous studies in volcanic areas. There are indications of an exposure

    We monitored the abundance of Ixodes scapularis Say (Acari: Ixodidae) and the Lyme disease incidence rate after the incremental removal of white-tailed deer, Odocoileus virginianus Zimmermann, within a suburban residential area to determine whether there was a measurable decrease in the abundance of ticks due to deer removal and whether the reduction in ticks resulted in a reduction in the incidence rate within the human population. After three seasons, the estimated deer population was reduced by 46.7%, from the 2002 postfawning estimate of 2,899 deer (45.6 deer per km2) to a 2005 estimate of 1,540 deer (24.3 deer per km2). There was no apparent effect of the deer culling program on numbers of questing I. scapularis subadults in the culling areas, and the overall numbers of host-seeking ticks in the culling areas seemed to increase in the second year of the program. The Lyme disease incidence rate generated by both passive and active surveillance systems showed no clear trend among years, and it did not seem to vary with declining deer density. Given the resources required to mount and maintain a community-based program of sufficient magnitude to effectively reduce vector tick density in ecologically open situations where there are few impediments to deer movement, it may be that deer reduction, although serving other community goals, is unlikely to be a primary means of tick control by itself. However, in concert with other tick control interventions, such programs may provide one aspect of a successful community effort to reduce the abundance of vector ticks.

    Research relevant to coping with grief for African American family members of homicide victims is limited. This retrospective study was conducted to determine the effects of gender, length of time since death, the traumatic impact of experiencing the homicide of a loved one, and the use of coping strategies to current grief reactions of African American family members of homicide victims (N = 44). Multiple regression analysis results suggest that gender and level of traumatic stress, related to posttraumatic stress symptomatology, predict current symptoms of grief. Women reported higher levels of current grief symptoms than men. Family members of homicide victims who reported higher levels of posttraumatic stress symptomology reported higher levels of current grief. Implications for research and recommendations for practitioners are discussed.

    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. PMID:26398193

    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.

    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.

    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.

  7. Life expectancy, economic inequality, homicide, and reproductive timing in Chicago neighbourhoods.

    In comparisons among Chicago neighbourhoods, homicide rates in 1988-93 varied more than 100-fold, while male life expectancy at birth ranged from 54 to 77 years, even with effects of homicide mortality removed. This "cause deleted" life expectancy was highly correlated with homicide rates; a measure of economic inequality added significant additional prediction, whereas median household income did not. Deaths from internal causes (diseases) show similar age patterns, despite different absolute levels, in the best and worst neighbourhoods, whereas deaths from external causes (homicide, accident, suicide) do not. As life expectancy declines across neighbourhoods, women reproduce earlier; by age 30, however, neighbourhood no longer affects age specific fertility. These results support the hypothesis that life expectancy itself may be a psychologically salient determinant of risk taking and the timing of life transitions. PMID:9154035

    The investigation of deaths of individuals whose bodies are decomposed, mummified, or skeletonized is particularly difficult for medical examiners and medicolegal death investigators. Determination of the cause and manner of death in such cases frequently requires consultation with experts in a variety of disciplines in the forensic sciences and necessitates correlation of the autopsy results, scene investigation, medical and social history of the deceased, and laboratory studies. The authors report an unusual case of an apparent homicide/suicide involving 2 individuals and a canine that went undetected for almost 4 years. Determination of the cause and manner of death in these cases involved a multidisciplinary, intercontinental investigation and necessitated the performance of toxicologic studies on specimens not commonly analyzed. These cases illustrate the importance of the multidisciplinary approach to medicolegal death investigations and the necessity of considering nontraditional sources of potential information and specimens for laboratory analysis in selected cases.

    2012-01-01

    Homicide followed by suicide (H-S) is a lethal event in which an individual kills another individual and subsequently dies by suicide. This article presents a review of research carried out in Asia, Australia, Canada, Europe, and the United States of America over the past 60 years on the prevalence of mental illness among the perpetrators of H-S. Analysis of the available data indicated a great disparity in the results of the different studies. Overall, depression was the most frequent disorder reported (about 39% of the cases in the 20 studies that assessed depressive disorders), followed by substance abuse (about 20% in 10 studies) and psychosis (about 17% in 11 studies). This review, therefore, indicated that mental illness plays an important role in H-S. The prevention of these events depends on the identification and treatment of psychiatric disorder in potential perpetrators.

    2004-02-01

    Explaining the phenomenon of male serial homicide has usually been approached from a psychiatric perspective. However, recent integrative theory suggests that cultural factors may play a role in shaping the psychology of young males with particular psychiatric and possibly neurological vulnerabilities in such ways as to facilitate converting the motivation to kill into actual behavior. Present results indicated that 34-45% of the interstate variation in rates of serial killer activity could be accounted for by three dimensions of local culture. Higher rates of male serial killer activity were associated with a local state culture supportive of game hunting and military training and a local culture supportive of punitive violence. The findings must be viewed with caution since societal variables are complex and the results are based on correlations which cannot be causally interpreted without more direct evidence of validity.

    To support police in reenacting criminal acts is one of the most important functions of forensic investigation. This case report deals with the discovery of the corpse of a 42-year old man at the bank of the river Inn. First of all the man was supposed to be drowned, but the autopsy showed a gunshot wound of the neck and a shot-through of the brain-stem. Intensive search for the weapon by the police and by divers was unsuccessful and therefore suspicion of homicide arose. The reconstruction of the act at the site of discovery of the corpse led to the discovery of the weapon and the case became clear to be a suicide.

    The analysis and reconstruction of forensically relevant events, such as traffic accidents, criminal assaults and homicides are based on external and internal morphological findings of the injured or deceased person. For this approach high-tech methods are gaining increasing importance in forensic investigations. The non-contact optical 3D digitising system GOM ATOS is applied as a suitable tool for whole body surface and wound documentation and analysis in order to identify injury-causing instruments and to reconstruct the course of event. In addition to the surface documentation, cross-sectional imaging methods deliver medical internal findings of the body. These 3D data are fused into a whole body model of the deceased. Additional to the findings of the bodies, the injury inflicting instruments and incident scene is documented in 3D. The 3D data of the incident scene, generated by 3D laser scanning and photogrammetry, is also included into the reconstruction. Two cases illustrate the methods. In the fist case a man was shot in his bedroom and the main question was, if the offender shot the man intentionally or accidentally, as he declared. In the second case a woman was hit by a car, driving backwards into a garage. It was unclear if the driver drove backwards once or twice, which would indicate that he willingly injured and killed the woman. With this work, we demonstrate how 3D documentation, data merging and animation enable to answer reconstructive questions regarding the dynamic development of patterned injuries, and how this leads to a real data based reconstruction of the course of event.

  13. Murder and robbery by vehicular impact: true vehicular homicide.

    PubMed

    Nadesan, K

    2000-06-01

    True vehicular homicides are defined as those occurrences in which a motor vehicle is intentionally used as a weapon in taking of a life. A case is presented in which the deceased was traveling in the front passenger seat of a motor car that was deliberately rammed by a heavy jeep that came in the opposite direction, resulting in a serious frontal collision. Immediately after the impact, while the occupants of the car were lying in a dazed condition, the two persons riding in the jeep escaped with a bag containing money that was in the car, leaving the jeep behind. The impact mainly involved the driver's sides of both vehicles. The driver of the car sustained serious injuries but was found to be alive, whereas the front-seat passenger, who did not show any serious external injuries, was found to be in a collapsed state and was pronounced dead on admission to the hospital within 30 minutes of the accident. The autopsy revealed that death was caused by closed hemopericardium from a ruptured right atrium. The evaluation of the external and internal injuries confirmed that the fatal injury and a few serious internal injuries were caused by the seat belt (tertiary-impact injuries). The ruptured right atrium was attributed to blunt abdominal trauma by impacting against the lap belt. The case was a true vehicular homicide in which a motor vehicle had been used as a weapon to kill a person. Various aspects pertaining to road accidents, the safety of the occupants, and the advantage and disadvantage of the safety devices are discussed.

    With populations aging there have been some concerns on elderly offending. We compared elderly homicide offenders with a younger comparison group with special emphasis on psychopathy. We analyzed nationwide register-based material on all homicide offenders aged 60 or older who were in a forensic psychiatric examination in Finland 1995-2004 and their gender-matched comparison group of younger homicide offenders. The offenders 60 years or older were diagnosed less often than the younger ones with drug dependence and personality disorders and more often with dementia and physical illnesses. The mean Psychopathy Checklist--Revised total scores as well as factor and facet scores were lower in the 60 or older age group. The group 60 years or older had significantly lower scores on eight individual items of social deviance. The interpersonal/affective factor 1 scores did not differ. Understanding the possible underlying phenomena of violent behavior may provide help for developing services for the elderly.

    In Medellín, Colombia, homicides have been the leading cause of death since 1986. Their proportion among total deaths increased from 3.5% in 1976 to 42% in 1991 and subsequently decreased to 7% in 2006. From 1979 to 2008, there were 81,166 homicides (annual mean, 2,706). The homicide rates per 100,000 inhabitants were 44 in 1979 and 47 in 2008, with a peak of 388 in 1991. The current article analyzes homicides in 30 years (1979-2008) using a random sample of 3,414 forensic autopsy reports. The vast majority of victims were males, 92.8% (95%CI: 91.8%; 93.6%), mostly low-income young people from 27 to 33 years of age. Most homicides involved revenge, fights, or armed robberies. The study showed different periods in the homicide epidemic: the first 15 years, with a rapid increase, the second, with a steady decline until 1998, and the third, with a fluctuating but overall steep decline in the last 10 years. This long-term study on violence in Medellin opens possibilities for analyzing and identifying more consistent policies for intervention.

  16. 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.

    A retrospective review of homicide cases among Aboriginal people in South Australia examined at Forensic Science SA was undertaken over a 40-year period from 1969 to 2008. A total of 90 Indigenous homicide victims were identified compared to 599 non-Indigenous victims over the same time period. Although homicide rates have fallen, the Indigenous homicide rate (ranging from 73.5 to 223.97 per 100,000) significantly exceeded the non-Indigenous rate (ranging from 8.16 to 12.6 per 100,000) for all decades (p<0.001). The most common methods of homicide in the Indigenous population involved blunt force and sharp force trauma, with gunshot, strangulation and other forms of homicides being encountered less often. While lack of access to firearms may explain the lower numbers of gunshot deaths it would not explain the low numbers of deaths due to strangulation. Considerable variability may, therefore, exist in the types of unnatural deaths that may be found in different cultural and ethnic groups, even within the same community.

    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.

    We investigated the role of the alcohol environment in explaining disparities in homicide rates among minorities in 10 cities in the United States using 2003 data from the Malt Liquor and Homicide study. We hypothesized that (a) higher concentrations of African Americans would be associated with higher homicide rates, as well as higher alcohol and malt liquor availability and promotion, and (b) the relationship between neighborhood racial/ethnic concentration and homicide would be attenuated by the greater alcohol and malt liquor availability and promotion in African American neighborhoods. Hypotheses were tested using separate Poisson, linear, and logistic regression models that corrected for spatial autocorrelation. Census block groups served as the unit of analysis (n = 450). We found that higher concentrations of African Americans were associated with higher homicide rates as well as greater alcohol availability, especially malt liquor availability. The promotion of malt liquor on storefronts was also significantly greater in African American than in other neighborhoods. However, none of the measures representing alcohol or malt liquor availability and promotion variables changed the effect of neighborhood racial/ethnic concentration on homicide. Limitations and implications of our findings are discussed.

    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.

    Rural areas of the Eastern Cape (EC) Province, South Africa have a high incidence of squamous cell oesophageal cancer (OC) and exposure to mycotoxin fumonisin has been associated with increased OC risk. However, to assess exposure to fumonisin in Xhosas--having maize as a staple food--it is necessary to determine the amount of maize consumed per day. A maize-specific food frequency questionnaire (M-FFQ) has recently been developed. This study developed a food photograph (FP) series to improve portion size estimation of maize dishes. Two sets of photographs were developed to be used alongside the validated M-FFQ. The photographs were designed to assist quantification of intakes (portion size photographs) and to facilitate estimation of maize amounts in various combined dishes (ratio photographs) using data from 24 h recalls (n = 159), dishing-up sessions (n = 35), focus group discussions (FGD) (n = 56) and published literature. Five villages in two rural isiXhosa-speaking areas of the EC Province, known to have a high incidence of OC, were randomly selected. Women between the ages of 18-55 years were recruited by snowball sampling and invited to participate. The FP series comprised three portion size photographs (S, M, L) of 21 maize dishes and three ratio photographs of nine combined maize-based dishes. A culturally specific FP series was designed to improve portion size estimation when reporting dietary intake using a newly developed M-FFQ.

    In the study described in this article, the authors examined the relationship between heavy metals in the drinking water and cancer densities in residential areas. The Turkish cities of Trabzon, Rize, and Giresun in the eastern Black Sea region were chosen as the study areas. Cancer registry data, population information, heavy metal chemical analysis results for drinking water, and other spatial information for the region were collected in a database designed in GIS. Information on a total of 13,012 registered cancer cases from the years 2000-2007 was obtained from a cancer record center and depicted spatially on a map. The incidence values explaining cancer density in residential units were calculated. Chemical analyses were then conducted to determine the presence of 17 different heavy metals by collecting a total of 541 drinking water samples. It was determined that among the 17 analyzed heavy metals, beryllium, nickel, antimony, and molybdenum had a significant relationship with cancer incidence values in the residential units.

    Cholangiocarcinoma (CCA) caused by opisthorchiasis is a specific public health problem in the Greater Mekong subregional countries. The Northeast Thailand is considered a world's prime area of CCA. Many epidemiological studies found the association between fruit and vegetables consumption and CCA, but their results were inconclusive. Therefore, this meta-analysis aimed to investigate the relationship between fruit and vegetables consumption and CCA prevention in the Northeast Thailand. The authors conducted a comprehensive search of scholarships on MEDLINE, EMBASE, and SCOPUS published during 1990 and 2015. Selected studies about fruit and vegetables consumption and CCA were analyzed. The fixed-effect model was used to estimate pool odds ratios for the consumption vs. nonconsumption. Based on a meta-analysis, consumption of mixed fruit [odds ratio (OR) = 0.79; 95% confidence interval (CI): 0.65-0.96], mixed vegetables (OR = 0.61; 95% CI: 0.50-0.75), and combined fruit and vegetables (OR = 0.68; 95% CI: 0.57-0.80) was associated with the reduction of CCA risk statistically. These findings support that fruit and vegetables consumption is associated with CCA risk reduction. If implemented in a larger geographical area, the study will shed light on possibilities to future reduction of CCA. Educators can replicate the study to solve CCA or other types of cancer and discover the best practice.

    From January 1992 to January 1993 the incidence of sudden cardiac death among the population of the Media Valle del Serchio area (Tuscany, Italy), composed of a population of 35,000, was found to be twice that of the European average; 32 cases have been reported over this period in that area (9 per 10,000 in the examined year), with a male/female (M/F) ratio of 2.5:1 (23 M, 9 F). In Italy the mean incidence of sudden death was calculated as 6/10,000 and in Europe 5/10,000. In the examined population hypertension was the coronary risk factor present most frequently (87%). A previous diagnosis of coronary artery disease was documented in 21 cases (66%); 5 of these exhibited previous myocardial infarction and 3 previous myocardial infarction associated with left ventricular heart failure. In 7 subjects no previous cardiovascular disorders were discovered. Prodromal symptoms had been reported in 20 cases (62%), which included chest pain in 8 and dyspnea in 8. In the examined geographic area a high prevalence of coronary artery disease was verified through the records of the Public Health Service, which documents the main causes of mortality in Tuscany, and through the hospitalization data and the services provided for ischemic heart disease at the local coronary care unit compared with the national average. Moreover, research was accomplished on physical and chemical properties of drinking water in the same area, and this revealed a very low total hardness due to the paucity of calcium and magnesium salts.(ABSTRACT TRUNCATED AT 250 WORDS)

    This study was undertaken to investigate whether there was any relation between the aurora borealis (measured as the geomagnetic activity) and the number of acute myocardial infarctions (AMI) in the northern, partly polar, area of Sweden. The AMI cases were collected from The Northern Sweden MONICA (multinational MONItoring of trends and determinants of CArdiovascular disease) AMI registry between 1985 and 1998, inclusive, and the information on the geomagnetic activity from continuous measurements at the Swedish Institute of Space Physics, Kiruna. In the analyses, both the relation between the individual AMI case and ambient geomagnetic activity, and the relation between the mean daily K index and the daily number of AMI cases were tested. We found no statistically significant relation between the number of fatal or non-fatal AMI cases, the number of sudden deaths or the number of patients with chest pain without myocardial damage, and geomagnetic activity. Our data do not support a relation between the geomagnetic activity and AMI.

    The present study examined posttraumatic stress disorder (PTSD) symptoms among friends and family members of homicide victims (homicide survivors). Out of a national sample of 1,753 young adults who completed follow-up interviews after participating in the National Survey of Adolescents, 268 homicide survivors and 653 victims of other interpersonal violence were selected for the study. Participants completed structured telephone interviews that covered the loss of a family member or close friend to homicide, violence exposure, and PTSD symptomatology. Findings indicated that 39% of homicide survivors met criteria for all 3 symptom clusters and 30% of homicide survivors met criteria for 2 PTSD clusters (functional impairment was not assessed). Multivariate logistic regression analyses demonstrated that homicide survivors were more likely than victims of other violence to meet criteria for all 3 PTSD symptom clusters (OR = 1.91, p < .05) and 2 symptom clusters (OR = 1.77, p < .05) when demographic characteristics and number of violent events were included in the model. These findings highlight the high prevalence of subthreshold PTSD symptoms among homicide survivors. Results suggest that homicide survivors are at elevated risk for PTSD symptoms in comparison to victims of other interpersonal violence.

    A case-controlled study of the incidence of heat-labile enterotoxin-producing Escherichia coli (LT+ETEC) and other enteric pathogens in travellers returning to the Sheffield area was conducted from May 1984 to April 1986. LT+ETEC were found in 35 (5.8%) of 600 travellers to developed countries (mainly popular Mediterranean holiday resorts), 36 (11.3%) of 320 travellers to less-developed countries, and 11 (0.9%) of 1282 control patients whose illness was not associated with recent travel abroad. A seasonal peak of LT+ETEC infection was observed only in travellers to developed countries, with infections being significantly commoner in August to October. There was no significant deviation from expected age/sex distribution of LT+ETEC infection. Strains of LT+ETEC from travellers produced more toxin than strains from control patients, strains from travellers to less-developed countries producing most of all. PMID:3053217

    Through the widespread use of postmortem computed tomography, inner livores of the lungs have become a frequently observed phenomenon in the field of forensic medicine. Yet their time-dependent development, notably in comparison with the widely studied external livores, remains poorly understood. We present a unique homicide case where the victim was discovered in supine position with correspondent external livores fixed exclusively on the rear side. Yet upon postmortem computed tomography, the victim presented pronounced inner livores within the depending dorsal areas of both lungs but also vertical sedimentation levels solely within the right lung, suggesting an initial right-hand side position and a postmortem re-positioning of the body. Interestingly, this was consistent with tangible hints of postmortem manipulation on-site. It is likely that this repositioning occurred sometime during the early postmortem interval (<6 h) as the external livores have completely rearranged to the final supine position. The presented case suggests different development patterns of inner and outer livores, highlighting the necessity for controlled studies that explore the formation and fixation processes of livor mortis in internal organs. A better understanding of these issues can prove useful in forensic examinations.

    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.

    In Medellín, Colombia, homicide has been the first cause of morbidity and mortality for 20 years. Medellín has the highest homicide rates of all major cities in Latin America. This study describes the victims, motives, and circumstances in homicides in Medellín from 1990 to 2002. The period included 55,365 homicides, of which 1,394 were randomly studied. Of this sample, 93.6% (95%CI: 92.2%-94.8%) were males, 77.0% (95%CI: 75.0%-79.5%) less than 35 years of age, one-fourth had consumed alcohol, and nine out of ten were killed with firearms. The main motives were revenge and armed robbery. 37.0% (95%CI: 34.0%-41.0%) of the victims lived in the lowest socioeconomic stratum of the city. Characteristics of homicides in Medellín have remained unchanged since the 1980s, when the most violent period in the city's history began. The most heavily affected groups are young males who live and die in poor neighborhoods, and the murders are individual acts that leave no wounded behind.

    Recent research has suggested that violent mortality may be socially patterned and a potentially important source of health inequalities within and between countries. Against this background the current study assessed socioeconomic inequalities in homicide mortality across Europe. To do this, longitudinal and cross-sectional data were obtained from mortality registers and population censuses in 12 European countries. Educational level was used to indicate socioeconomic position. Age-standardized mortality rates were calculated for post, upper and lower secondary or less educational groups. The magnitude of inequalities was assessed using the relative and slope index of inequality. The analysis focused on the 35-64 age group. Educational inequalities in homicide mortality were present in all countries. Absolute inequalities in homicide mortality were larger in the eastern part of Europe and in Finland, consistent with their higher overall homicide rates. They contributed 2.5% at most (in Estonia) to the inequalities in total mortality. Relative inequalities were high in the northern and eastern part of Europe, but were low in Belgium, Switzerland and Slovenia. Patterns were less consistent among women. Socioeconomic inequalities in homicide are thus a universal phenomenon in Europe. Wide-ranging social and inter-sectoral health policies are now needed to address the risk of violent victimization that target both potential offenders and victims.

    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.

    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

    This work shows a first approximation to the magnitude and characteristics of mortality by homicide in homosexuals in Mexico using the cases registered between the years 1995 and 2000. A statistical analysis was performed of the homicides against homosexuals that were registered through the review of newspaper articles published by the National Press. Sex, age of the victims, kind and number of weapons used, wounds endured, and the situation in which the corpses found were registered. The greater mortality by homicide due to homosexual orientation was recorded in men (95%); it was found that the cases accumulated in the cohort of the third and fourth decades of their age (43%). The homicides were characterized by extreme violence which included the use of various arm types (33%) and wounds (32%). The most frequent situations that occurred were finding the corpses naked and tied (13%). The features of the homicide against homosexuals are associated to the general attributes of the predominant masculinity model; therefore, at a macro social level, some reasons are found in the social construction of homophobia. The degree of violence in these crimes adduces the consideration that they are hate crimes.

    We hypothesized that the integration of forensic psychiatrists and the forensic system into the general stream of mental health should lead to better reintegration of forensic patients into the society. The aims of the study were to explore the link between violence, murder, psychiatric disorders and other variables, and to suggest a mode of prevention of criminal recidivism. This investigation provided a more reflective profile of mentally ill persons convicted of murder, hospitalized in Psychiatric Hospital in Demir Hisar in Macedonia between 2007 and 2009. Study results indicated the offender with severe mental illness incarcerated for murder in Demir Hisar Psychiatric Hospital to be predominantly suffering from a mood disorder, to be a male with secondary school education, and to have significant intimate and family relationships characterized by rage as a frequently mentioned motive for murder. On committing homicide, they frequently used firearm or sharp objects. The offenders lived in dysfunctional families, had extensive histories of substance abuse and criminal activity before their murder conviction, and received inadequate treatment for their mental disorder and substance abuse. We suggest that the offenders (murderers) continue their treatment in mental health forensic services upon completing their obligatory treatment at a psychiatric hospital.

    We report the use of immunohistochemical staining for analysis of forensic evidence from a double homicide. A 38-year-old woman and her 7-year-old daughter were murdered by multiple blows to the head and face with a tomahawk, resulting in multiple fragments of brain tissue scattered about the murder scene. The victims' husband and father was the main suspect, who maintained that he was out of town on business during the evening of the murders. However, a shirt taken from the suspect's car on the morning after the murders (secured by the police before the suspect visited the murder scene) was found to have two small stains. DNA analysis on the stains showed the presence of the deceased wife's DNA, and immunohistochemical stains on shirt fragments conclusively documented the presence of deep central nervous system tissue, providing the critical piece of evidence needed to arrest and prosecute the suspect. This report demonstrates that shirt or similar cloth fragments can be processed into paraffin blocks and subsequently immunostained to search for and classify types of tissue fragments that may be present on the fabric.

    We retrospectively reviewed 35 autopsy cases where death had resulted from homicidal sharp force injuries and compared cases where the injuries had been inflicted by family members or relatives (relative group) with cases where the injuries had been inflicted by an unrelated person (stranger group). We reviewed the age and sex of the victims, the number of stab wounds, the site of the stab wounds, the presence of defence wounds, the detection of alcohol and other drugs and the mental status of the victims and perpetrators. We found the following tendencies: (a) a female victim was more frequently killed by a relative than by a stranger; (b) the percentage of cases receiving a single stab wound and the percentage of cases receiving more than ten stab wounds were both unexpectedly higher in the relative group than in the stranger group, and (c) in the stranger group, when there were no defence wounds, the victim had usually consumed alcohol, whereas when there were neither defence wounds nor alcohol intake, the case usually fell into the relative group. These tendencies will contribute towards our forensic appraisement in autopsy cases resulting from sharp force injuries.

    Neurological soft signs (NSS) are characterized by abnormalities in motor, sensory, and integrative functions. NSS have been regarded as a result of neurodevelopmental dysfunction, and as evidence of a central nervous system defect, resulting in considerable sociopsychological dysfunction. During the last decade there has been growing evidence of brain dysfunction in severe aggressive behavior. As a symptom, aggression overlaps a number of psychiatric disorders, but it is commonly associated with antisocial personality disorder. The aim of the present study was to examine NSS in an adult criminal population using the scale by Rossi et al. [29]. Subjects comprised 14 homicidal men with antisocial personality disorder recruited from a forensic psychiatric examination. Ten age- and gender-matched healthy volunteers as well as eight patients with schizophrenia, but no history of physical aggression, served as controls. The NSS scores of antisocial offenders were significantly increased compared with those of the healthy controls, whereas no significant differences were observed between the scores of offenders and those of patients with schizophrenia. It can be speculated that NSS indicate a nonspecific vulnerability factor in several psychiatric syndromes, which are further influenced by a variety of genetic and environmental components. One of these syndromes may be antisocial personality disorder with severe aggression.

    The increasing involvement of girls under 18 in violent crime has been a matter of growing concern in the United States in recent years. This article reviews the arrests of female juveniles for violent crime and then focuses specifically on their involvement in homicide. Arrests of girls for murder, unlike arrests for assault, have not risen over the last 30 years, suggesting that the dynamics that propel female juveniles to engage in lethal violence differ from those contributing to assaultive behavior by this same group. A review of the literature indicates that theories as to why female adolescents kill do not take into account recent scientific findings on brain development and the biological effects of early trauma in explaining serious violent behavior by girls. Three cases, evaluated by the authors, involving female adolescents charged with murder or attempted murder, are presented. The authors focus on the biological and psychological dynamics that help explain their violent behavior. They discuss the effects of insecure attachment and child maltreatment, and trace a critical pathway between these early experiences and future risk of violent behavior. The dynamics of child maltreatment in fostering rage and violence are discussed thereafter in terms of offender accountability. The article concludes with a discussion of treatment and recommendations for future research.

    This paper presents a new model that predicts the number of freeway incidents and associated delays based on general freeway segment characteristics, traffic volumes, and incident management procedures. The model is intended to be used in planning capacity-enhancing freeway improvements and incident management programs. Estimates of incident frequencies, severity, durations, and delays are provided for seven standard incident types, each of which represents a significant fraction of total unplanned incidents and has severity and/or duration characteristics substantially different from the others. In addition to describing the incident prediction model, the paper addresses the need for a coordinated national strategy for collecting incident data, with particular attention to urban freeways. It concludes that the incident data systems that have evolved in several urban areas, often in connection with freeway service patrols and incident response team activities, already provide a valuable nationwide data resource for understanding incident patterns and their variations. However, better national coordination of locally collected incident data would be helpful for addressing issues beyond the scope of the local concerns for which virtually all current systems were originally designed. Specific areas for improvement include the definitions of incident types, descriptions of incident locations (relative to both the length and breadth of the highway), and data recording the critical times during incidents such as when detection, response, and clearing occur.

    Although the crime of homicide has received significant attention from scholars, little research exists that examines the impact of homicide on surviving family members. Because opportunities for victims and family members of victims to participate in the criminal justice system are increasing, it is important to understand the impact of these forms of participation on those who choose to participate. This study uses data from focus groups to examine the experiences of homicide survivors within the criminal justice system, including views about how system involvement and specific outcomes (i.e., sentencing) may help or hinder healing. Findings suggest that many families leave the criminal justice system feeling marginalized and revictimized. This study calls into question the current criminal justice system's ability to meet the needs of crime victim and their families.

    The authors investigated posttraumatic stress disorder (PTSD) symptoms in Japanese bereaved family members using a questionnaire. Participants were bereaved as a result of suicide and homicide (n = 51 and 49, respectively), with natural death (n = 56) as a control; and their relationships to the deceased were parent-child (n = 79), conjugal (n = 42), and others (n = 35). With regard to the 3 main PTSD-related criteria, (a) re-experiencing symptoms were not dependent on the manner of death or the relationship to the deceased; (b) avoidance behaviors were more highly related to homicide than natural death for relatives other than parent-child and conjugal relationships; and (c) hyperarousal and maladaptation symptoms were more serious for conjugal loss. These findings suggest that avoidance behaviors in homicidal cases are more closely associated with a distant family relationship, whereas conjugal loss is traumatic, irrespective of the manner of death, often causing hyperarousal and maladaptation symptoms.

  8. Co-victims of Homicide: A Systematic Review of the Literature.

    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.

    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.

    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.

    The current study presents the results of an analysis of serious and assaultive prison rule violating behavior among male perpetrators of intimate partner homicide (IPH). Data on prison rule violations were collected from a sample of 189 inmates convicted of IPH in a large, southern prison system. The study focused on the degree of continuity in violent behavior among IPH offenders from the community to the prison setting. The current study tested hypotheses derived from both the feminist perspective (FP) and the general violence perspective (GVP). As a group, IPH offenders were better behaved in prison than other incarcerated homicide offenders, thereby offering some support for the FP. However, the lower level of assaultive behavior among the group was not universal. Characteristics associated with continued violent offending in the prison environment were the same as those found in previous studies of incarcerated homicide offenders, thereby lending greater support to the GVP.

  12. 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.

    2016-02-01

    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.

    Homicide causes negative unintended consequences for family survivors. Family survivors face complicated grief and overwhelming loss with minimal support from others. The authors offered a retreat intervention as a way to ameliorate the effects of the homicidal death for family survivors of homicide. An exploratory longitudinal pilot study examined the feasibility and acceptability of the intervention and explored the impact of the TOZI© Healing intervention on participants' distress symptoms. Eight family members participated in the 2-day retreat and completed surveys at five time intervals over 30 months. Descriptive statistics and correlations were used to analyze the data. Although sample sizes were too small to achieve statistical significance, changes on selected holistic health outcomes, supported by overwhelmingly positive focus group responses to the intervention, affirm the need for further study.

    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.

    The distribution of time from acute traumatic injury to death has three peaks: immediate (less than or equal to one hour), early (6 to 24 hours), and late (days to weeks). It has been suggested that coordinated trauma care dampens the late peak; however, this research may be more reflective of unintentional than intentional deaths. This study examines whether a coordinated trauma system (TS) alters the temporal distribution for assault-related deaths. Data were obtained from homicides examined by the Jefferson County Coroner's/Medical Examiner's Office from 1987 to 2008. Homicides were categorized-based on year of death-as occurring in the presence of no TS, during TS implementation, in the early years of the TS, or in a mature TS. The temporal distribution of homicide mortality was compared among TS categories using a χ(2) test. A Cox Markov multistate model was used to estimate proportional changes in the temporal distribution of death adjusted for assault mechanism. With a TS, after adjusting for assault mechanism, a lower proportion of homicide victims survived through the first hour (hazard ratio [HR], 0.75; 95% confidence interval [CI], 0.54 to 1.03) and from one to six hours (HR, 0.68; 95% CI, 0.49 to 0.96). Additionally, the presence of a TS was associated with a proportional decrease in deaths after 24 hours (P = 0.0005). These results suggest that a trauma system is effective in preventing late homicide deaths; however, other means of preventing death (such as violence prevention programs) are needed to decrease the burden of immediate homicide-related deaths.

    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.

  18. Psychopathy (PCL-R) in a forensic psychiatric sample of homicide offenders: some reliability issues.

    PubMed

    Laurell, Jenny; Dåderman, Anna Maria

    2007-01-01

    Several studies have shown that psychopathy is overrepresented among homicide offenders. There is a consensus that Hare's Psychopathy Checklist-Revised PCL-R is currently the most valid and useful tool for rating psychopathy (e.g., [Fulero, S. M. (1995). Review of the Hare Psychopathy Checklist-Revised. In J. C. Conoley & J. C. Impara (Eds.), Twelfth Mental Measurements Yearbook (pp. 453-454). Lincoln, NE: Buros Institute]). Usually, when making a rating of psychopathy, both an interview and an examination of the subject's files are used. However, it has been discussed what is really required to be able to rate psychopathy in a reliable manner. The aim of the present study was to retrospectively rate the degree of psychopathy in 35 homicide offenders being subjected to forensic psychiatric assessment. These ratings of psychopathy were carried out using forensic psychiatric files and courts'; verdicts only. Another aim was to examine the reliability of PCL-R in this specific Swedish sample of homicide offenders. There was a good agreement between the two raters with respect to the categorical diagnosis of psychopathy (Cohen's kappa=.81, p<.001), which indicates that retrospective ratings of psychopathy are well suited for research purposes. The prevalence of psychopathy among the homicide offenders was 31.4% (using a cut-off score of 30), which means that the construct of psychopathy may contribute to the understanding of the phenomenon of homicide. In the planning of treatment for homicide offenders, a consideration of possible psychopathy is necessary. As criminal psychopaths are known to relapse into violent criminality, it is very important that they are given efficient treatment, placement and management.

    Homicide survivors are at increased risk for mental health problems, including depression, posttraumatic stress disorder, and complicated grief. Therefore, improving access to community and mental health resources is critical for this population. The atuhors sought to examine barriers to accessing services and service satisfaction among 47 homicide survivors. Over half of the sample met criteria for a mental disorder, with depression being the most prevalent problem. Frequently endorsed barriers to care included financial barriers, inadequate information, and health-related problems. However, participants who engaged in services were generally satisfied with those services. Only depression was uniquely associated with worse overall service satisfaction.

    This work examines the perception by cold case homicide covictims that police have given up trying to solve their loved one's murder. A random sample (n = 65) of cold case homicide covictims is surveyed to determine if, and how, different forms of communication may be important in their perceptions about police. Ordered logistic regression analyses indicate that perceived importance of the information communicated, frequency of police contact, and satisfaction with communication efforts by police are inversely correlated with covictims' perceptions that police have given up on the investigation. These inverse correlations persist despite statistical controls and have important implications for the bereavement of covictims and for crime rates.

    This study explored differences in intimate partner homicides (IPHs) among Asian Americans. Data from newspapers and femicide reports by different state coalitions on 125 intimate partner killings occurring between 2000 and 2005 were analyzed. Men were the perpetrators in nearly 9 out of 10 cases of Asian IPHs. Gender differences were found in ages of victims and perpetrators, types of relationship between partners, and methods of killing. Most homicides occurred among South-east Asians, and East Asians had the highest within-group proportion of suicides. The findings call for culturally competent risk assessment and intervention strategies to prevent IPHs among at-risk Asian Americans.

    Domestic violence imposes a large cost on society. The authors exploit state variation in timing to examine the impact of three types of law on intimate partner homicides. These laws restrict access to firearms by individuals who are subject to a restraining order or have been convicted of a domestic violence misdemeanor or allow law enforcement officers to confiscate firearms at a domestic violence scene. The authors find that female intimate partner homicide rates decline 7% after a state passes a restraining order law. They find no effect from the domestic violence misdemeanor or confiscation laws.

    The case of a 24-year-old African American man who committed serial sexual homicide and who met criteria (Hare, 1991) for psychopathy is presented. His Thematic Apperception Test (Murray, 1943) responses were used to code key aspects of personality organization--object relations and defense mechanisms--via the Social Cognition and Object Relations Scale (Westen, Lohr, Silk, & Kerber, 1989) and the Defense Mechanisms Manual (Cramer, 1991), respectively. Severe object relations pathology and a reliance on the defense mechanism of immature projection and immature denial are noted. Findings are relatively consistent with previous psychodynamic Rorschach studies of psychopathic sexual homicide perpetrators (Gacono, Meloy, & Bridges, 2000; Meloy, Gacono, & Kenney, 1994).

    Arrhythmogenic right ventricular cardiomyopathy (ARVC), also known as arrhythmogenic right ventricular dysplasia, is a known cause of sudden unexplained death in young, otherwise healthy adults. In the forensic setting, several cases of fatal ARVC have been reported, mostly occurring during physical exercise. However, a very few cases present where the death scene is mistaken for a homicide. We report here the case of a 23-year-old woman, found dead, lying in the snow on an isolated property. The woman's genitals were exposed, with her trousers down over her thighs. Rape homicide was strongly suspected, but autopsy findings proved otherwise.

    The Gargano, also known as the 'Spur of Italy', is a sub-region of Italy which is located in North of Puglia, in the Province of Foggia. A ravine located in this area was used as a dumping ground in past. During a clearing operation, a team of speleologists discovered human skeletal remains, which led to an official investigation by the local prosecutor's office. The prosecutor called a team of forensic specialist for a scene investigation to recover and identify the human skeletal remains. Four different human skeletal remains located at four different levels of depth underground were found and were in different conditions. A complete forensic investigation was initiated and comprised of radiological imaging with DNA profiling. Three of the four human skeletal remains that were found were identified as those belonging to men who vanished mysteriously in the nineties. The studies conducted have demonstrated that the victims found were murdered and the murders were attributed to the "Mafia of Gargano". The Mafia of Gargano was officially recognized as a criminal organization dating back to 2009 and their criminal activities included the smuggling of firearms and cigarettes, human trafficking, and smuggling of undocumented immigrants. Murders in which corpses are made to disappear is common practice in criminal activities including that of the Italian Mafia. The "Lupara Bianca" is a colloquial term commonly used in Sicily to refer to concealed murders. To the best of our knowledge, this is the first reported study describing the discovery of one of the locations used extensively by the local Mafia as a "cemetery" for victims of "Lupara Bianca" homicides. Based on evidences collected at the site, an explanation of this homicidal modality will be provided.

    The spatial dynamics of criminal activities has been recently studied through statistical physics methods; however, models and results have been focusing on local scales (city level) and much less is known about these patterns at larger scales, e.g. at a country level. Here we report on a characterization of the spatial dynamics of the homicide crimes along the Brazilian territory using data from all cities (˜5000) in a period of more than thirty years. Our results show that the spatial correlation function in the per capita homicides decays exponentially with the distance between cities and that the characteristic correlation length displays an acute increasing trend in the latest years. We also investigate the formation of spatial clusters of cities via a percolation-like analysis, where clustering of cities and a phase-transition-like behavior describing the size of the largest cluster as a function of a homicide threshold are observed. This transition-like behavior presents evolutive features characterized by an increasing in the homicide threshold (where the transitions occur) and by a decreasing in the transition magnitudes (length of the jumps in the cluster size). We believe that our work sheds new light on the spatial patterns of criminal activities at large scales, which may contribute for better political decisions and resources allocation as well as opens new possibilities for modeling criminal activities by setting up fundamental empirical patterns at large scales.

    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 aggregate relationship between homicide and alcohol availability is well established across a number of national and sub-national settings in North America, Europe and some parts of Asia. However, results linking youth homicide and alcohol availability at the retail level are largely absent from the literature, especially at the city level and across longer time periods. In a multivariate, pooled time series and cross-section study, youth homicide offending rates for two age groups, 13-17 and 18-24, were analysed for the 91 largest cities in the USA between 1984 and 2006. Data for social and economic characteristics, drug use, street gang activity and gun availability were also used as time series measures. Data on the availability of alcohol for each city were gathered from the US Census of Economic Activity, which is conducted every 5 years. These data were used to construct an annual time series for the density of retail alcohol outlets in each city. Results indicated that net of other variables, several of which had significant impacts on youth homicide, the density of alcohol outlets had a significant positive effect on youth homicide for those aged 13-17 and 18-24. Such positive effects have been found for adults in national and neighbourhood level studies, but this is the first study to report such evidence for teenagers and young adults. An important policy implication of these findings is that the reduction of the density of retail alcohol outlets in a city may be an effective tool for violent crime reduction among such youth.

    Background Homicide of children is a global problem. The under-5-y age group is the second largest homicide age group after 15–19 y olds, but has received little research attention. Understanding age and gender patterns is important for assisting with developing prevention interventions. Here we present an age and gender analysis of homicides among children under 5 y in South Africa from a national study that included a focus on neonaticide and infanticide. Methods and Findings A retrospective national cross-sectional study was conducted using a random sample of 38 medico-legal laboratories operating in 2009 to identify homicides of children under 5 y. Child data were abstracted from the mortuary files and autopsy reports, and both child and perpetrator data data were collected from police interviews. We erred towards applying a conservative definition of homicide and excluded sudden infant death syndrome cases. We estimated that 454 (95% CI 366, 541) children under the age of 5 y were killed in South Africa in 2009. More than half (53.2%; 95% CI 46.7%, 59.5%) were neonates (0–28 d), and 74.4% (95% CI 69.3%, 78.9%) were infants (under 1 y), giving a neonaticide rate of 19.6 per 100,000 live births and an infanticide rate of 28.4 per 100,000 live births. The majority of the neonates died in the early neonatal period (0–6 d), and abandonment accounted for 84.9% (95% CI 81.5%, 87.8%) of all the neonates killed. Distinct age and gender patterns were found, with significantly fewer boy children killed in rural settings compared to urban settings (odds ratio 0.6; 95% CI 0.4, 0.9; p = 0.015). Abuse-related killings and evidence of sexual assault were more common among older girls than in all other age and gender groups. Mothers were identified as the perpetrators in all of the neonaticides and were the most common perpetrators overall (71.0%; 95% CI 63.9%, 77.2%). Abandoned neonates were mainly term babies, with a mean gestational age of 38 wk. We did not have

    Between 1995 and 1997, in the territories of Southern Italy, there were fifteen murders of elderly women over the age of 70 years old. Initially, however, not all the murders were attributed to a single serial killer. The majority of the victims were stabbed multiple times in the neck, except for three cases in which the cause of death was manual strangulation. There was evidence of sexual assault in only one of the cases. All the victims were discovered in their own apartments, which were located on the ground level, with no signs of forced entry. In most of the cases, the offender stole money and/or jewellery. A multi-disciplinary team reviewed the cases during the investigation and created a profile of the killer. The team determined that the method of operation was completely unusual for the local criminal element. They suggested that the perpetrator could be an immigrant, who committed the murders for sexual motivation and who may have been arrested previously for sex-related incidents. On 15th September 1997, a suspect was arrested. He was identified as Ben Mohamed Ezzedine Sebai, a 35-year-old white male, originally from Tunisia. He was charged and convicted of four of the murders and was given a life sentence. In 2005, Sebai confessed to the murders of four additional elderly women, for which nine other people had already been previously tried and convicted, among them, a man who committed suicide in jail. In 2007, Sebai finally confessed to committing fifteen murders that occurred between 1995 and 1997. Sebai also admitted to experiencing sexual gratification at every homicide scene, even though there was no physical proof at most of the crime scenes. The goal of this article is to illustrate a little-known but noteworthy case concerning a serial sexual killer of elderly women that occurred in Southern Italy, highlighting the method of operation, the victim selection process, and the injuries inflicted. The article will also discuss his motivation, the

    As 70% of the killings of women takes place in the context of relational dynamics and in 80% of the cases the perpetrator is a man, we can presume that femicide constitutes much of the homicide mortality among women. Epidemiological surveillance of the killings of women can, therefore, provide indicators on the trends and geographical distribution of femicide and, indirectly, of the more general phenomenon of harassment and violence against women. The analysis of 40 years of mortality shows only a slight decrease of the murders of women nationwide. This suggests that the factors that underline this phenomenon are deeply rooted in the relationship between men and women. The decrease has taken place mainly in the South and Islands and the percentage SMRs point to a reversal of the relationship between geographic areas: thus, at the end of the observation period the North-West assumes a greater weight than the South and Islands. So we cannot exclude that part of the decrease in murders of women can be attributed to the overall decrease in homicides related to criminal activity, most pronounced in the South and Islands.

  7. Dramatic reduction of liver cancer incidence in young adults: 28 year follow-up of etiological interventions in an endemic area of China

    Qidong City, China, has had high liver cancer incidence from endemic hepatitis B virus (HBV) infection and dietary exposure to aflatoxin. Based on etiologic studies, we began interventions in 1980 to reduce dietary aflatoxin and initiate neonatal HBV vaccination. We studied trends in liver cancer incidence rates in the 1.1 million inhabitants of Qidong and examined trends in aflatoxin exposure, staple food consumption, HBV infection markers and annual income. Aflatoxin exposure declined greatly in association with economic reform, increased earnings and educational programs to shift staple food consumption in the total population from moldy corn to fresh rice. A controlled neonatal HBV vaccination trial began in 1983 and ended in November, 1990, when vaccination was expanded to all newborns. Liver cancer incidence fell dramatically in young adults. Compared with 1980–83, the age-specific liver cancer incidence rates in 2005–08 significantly decreased 14-fold at ages 20–24, 9-fold at ages 25–29, 4-fold at ages 30–34, 1.5-fold at ages 35–39, 1.2-fold at ages 40–44 and 1.4-fold at ages 45–49, but increased at older ages. The 14-fold reduction at ages 20–24 might reflect the combined effects of reduced aflatoxin exposure and partial neonatal HBV vaccination. Decrease incidence in age groups >25 years could mainly be attributable to rapid aflatoxin reduction. Compared with 1980–83, liver cancer incidence in 1990–93 significantly decreased 3.4-fold at ages 20–24, and 1.9-fold at ages 25–29 when the first vaccinees were <11 years old. PMID:23322152

    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.

    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.

    In medicine real severe mishaps are rare. On the other hand critical incidents are frequent. Anonymous critical incident reporting systems allow us to learn from these mishaps. This learning process will make our daily clinical work safer Unfortunately, before these systems can be used efficiently our professional culture has to be changed. Everyone in medicine has to admit that errors do occur to see the need for an open discussion. If we really want to learn from errors, we cannot punish the individual, who reported his or her mistake. The interest is primarily in what has happened and why it has happened and not who has committed this mistake. The cause for critical incidents in medicine is in over 80% the human factor Poor communication, work under enormous stress, conflicts and hierarchies are the main cause. This has been known for many years, therefore have already 15 years ago high-tech industries, like e.g. aviation, started to invest in special courses on team training. Medicine is a typical profession were until now only the individual performance decided about the professional career Communication, conflict management, stress management, decision making, risk management, team and team resource management were subjects that have never been taught during our preor postgraduate education. These points are the most important ones for an optimal teamwork. A multimodular course designed together with Swissair (Human Aspect Development medical, HADmedical) helps to cover, as in aviation, the soft factor and behavioural education in medicine and to prepare professionals in health care to work as a real team.

    Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a major public health threat. In this retrospective cohort study, we included patients with laboratory-confirmed MRSA infections treated at Children's National Medical Center in Washington, District of Columbia between July 2003 and December 2010. The secular trends in the incidence rates of skin/soft tissue and invasive MRSA infections were assessed. Molecular analyses were performed on a subset of patients with invasive infections whose MRSA isolates were available for genotyping. The study identified 3750 patients with MRSA infections. The incidence of MRSA infections peaked in 2007 (incidence rate: 5.34 per 1000 patient-visits) and subsequently declined at a rate of 5% per year. By December 2010, the MRSA incidence rate reached 3.77 per 1000 patient-visits. Seventeen (14.7%) patients with invasive MRSA infections died, and the mortality risk significantly increased if the MRSA infections were healthcare-associated (HA) or if an isolate was resistant to clindamycin and/or trimethoprim/sulfamethoxazole. In conclusion, this study described a descending trend in MRSA infections in children since 2007. Although invasive MRSA infections only accounted for a small portion of the total MRSA infections, they were associated with a high mortality risk. The prevention and control of the spread of MRSA remains a crucial and challenging task. PMID:26038439

    Background Neisseria gonorrhoeae (N. gonorrhoeae) is one of the most prevalent non-ulcerative sexually transmitted infections (STIs) in China, however, the data about N. gonorrhoeae infections are limited in this population. The objective of this study is to determine N. gonorrheae incidence and associated risk factors among female sex workers (FSWs) in China. Methods This serial cross-sectional study was conducted semi-annually among FSWs in a City of Yunnan Province, which constituted an open cohort study. Participants were interviewed and tested for N. gonorrhoeae every 6 months. Results During 3 years of follow-up, 64 incident cases of N. gonorrhoeae infection were diagnosed, yielding an overall incidence of 5.9 per 100 person years (PY) (95% confidence interval (CI), 4.53–7.41). Working in higher risk commercial sex venue (adjusted hazard ratio (AHR)=2.7, 95% CI, 1.56–4.55), inconsistently use condom with clients in previous week (AHR=1.9, 95% CI, 1.07–3.35) and being infected with C. trachomatis (AHR=1.9, 95% CI, 1.06–3.26) were independent risk factors for incident N. gonorrhoeae infection. Conclusions A relatively high prevalence and incidence of N. gonorrhoeae among a prospective cohort of FSWs underscore the urgency for traditional HIV/STIs prevention methods among FSWs, such as condom promotion, screening and treatment of STIs, considering the high prevalence of STIs. Significant attention should focus on FSWs working in higher risk commercial sex venues as they are at higher risk for N. gonorrhoeae and transmission than those in lower risk commercial sex venues.

    Nearly one in seven homicides worldwide involve killing of an intimate partner, and men are four times more likely to be the perpetrators of these offenses. This article is a review of the literature on male perpetrators of intimate partner homicide (IPH) with an emphasis on the demographic, psychiatric, situational, and motivational characteristics consistently identified across diverse posthomicide samples. The existing literature supports the heterogeneity among male perpetrators of IPH. Based on patterns that emerge in the literature, a preliminary typology is described that includes four generally distinct subtypes of male IPH perpetrators: the mentally ill, the undercontrolled/dysregulated, chronic batterer, and overcontrolled/catathymic subtypes. Forensic implications related to risk assessment, risk management, and criminal intent are considered, and suggestions for future targeted research aimed at validating the proposed typology are offered.

    Report about a homicide case, where a female taxi driver was killed by a shot through the neck. The partly confessing perpetrator maintained that he had shot the woman by using a signal pen loaded with a signal cartridge. The lethal injuries were not compatible with the averment of the perpetrator. Shooting experiments were performed using the signal pen loaded with signal cartridges as well as using the signal pen connected with a short barrel (= pen gun) and loaded with small-bore bullets (cal. .22). Shots were done through a flash ranging chronograph and to the cervical spines of slaughtered calfs. The ballistic data compared with the wound morphology led to the reconstruction of the homicide.

    In homicide investigations, it is critically important that postmortem interval and postburial interval (PBI) of buried victims are determined accurately. However, clandestine graves can be difficult to locate; and the detection rates for a variety of search methods (ranging from simple ground probing through to remote imaging and near-surface geophysics) can be very low. In this study, simulated graves of homicide victims were emplaced in three sites with contrasting soil types, bedrock, and depositional environments. The long-term monthly in situ monitoring of grave soil water revealed rapid increases in conductivity up to 2 years after burial, with the longest study evidencing declining values to background levels after 4.25 years. Results were corrected for site temperatures and rainfall to produce generic models of fluid conductivity as a function of time. The research suggests soilwater conductivity can give reliable PBI estimates for clandestine burials and therefore be used as a grave detection method.

    This cross-sectional epidemiological study aimed to calculate the potential years of life lost by female homicide victims in Recife, Pernambuco State, Brazil, in 2003-2007. A database was used from the Operational Division for Information on Births and Deaths under the Recife Municipal Health Department. All death certificates for childbearing-age women were reviewed for the five-year period. The results showed a total of 12,120 potential years of life lost by these women, mostly young, black (88%), with unknown levels of schooling (78.2%), single (80%), in District III of the city, and murdered with firearms in their own homes. The specific mortality rate was 10.8 homicides per 100,000 childbearing-age women. The 43.3 years of life lost per woman express the city's characteristics, poverty levels, unemployment, population density, residential instability, and social inequality, exposing residents to social strife, crime, and violence.

    The aim of our study was to assess the value of ISS to estimate survival time in a retrospective study of all homicidal deaths in the Western suburbs of Paris between 1994 and 2008. Stab wounds were the most common cause of death. Survival time between assault and death, determined in 107 cases out of 511 homicide cases, ranged from 0 min to 25 days (mean 39 h). There was an overall significant association between the survival time and the ISS score. ISS and survival time were strongly associated with male victims and a clear trend was seen with women. Regarding the type of wounds, a trend was seen with gunshot wounds and blunt injuries, but not with stab wounds. There was no influence of blood toxicological results and resuscitation attempts. Overall, ISS was a good predictor of a survival under 30 min.

    We report a rare case of homicide by hanging. The postmortem examination resulted in a verdict of death by suicidal hanging and the Public Prosecutor's Office released the body for burial. After intervention by the relatives police investigations were resumed. Based on evidence impossible to reconcile with the results of the postmortem examination and requiring further clarification, an autopsy was ordered. The results of the postmortem could not be brought in line with a suicidal hanging and were further substantiated by DNA analysis. The scenario put forward by the defense claiming a secondary transfer of trace evidence onto the ligature and the victim's clothes was excluded because of the distribution pattern and the trace evidence ratio. The defendant was sentenced to 20 years of prison for homicide. The verdict was confirmed by the Supreme Court and commuted to 18 years.

    The frequency of serial sexual murder has been widely discussed, and estimates of the number of victims in the United States range from 500 to 6000 per year. This study attempted to quantify the number of serial sexual murder victims in Virginia for a ten-year period. Multiple sources of data were utilized, including Federal Bureau of Investigation (FBI) case files, FBI's Violent Criminal Apprehension Program (ViCAP) reports, Virginia State Police ViCAP reports, Virginia Homicide Investigators Association, and the Virginia Division of Forensic Science DNA database, to effectively cull out all the known serial sexual murder victims for the given time period. Review of these records revealed a total of 28 victims of serial sexual murder, compared with a total of 5183 murder victims for the same ten-year period. The frequency of serial sexual victimization was 0.5% of all homicides for the given period. These results highlight the unusual frequency of serial sexual murder.

    Trauma and violence represent the domains of forensic medical expertise. The objective finding on the victim of the homicide makes it possible to reconstruct the way and mechanism of the injury connected with it and thus to determine the cause of death. The traces of violence contain many indices pointing at specific personal characteristics of the culprit, his motivation to the crime and his state of mind at the time of the homicide. To judge the penal responsibility and the guilt of the culprit it is important for the court to have the analysis of the dynamics and of the causal background of the crime, especially the synthetic evaluation of subjective, situation, or eventually psychological factors of violence with the mortal effect. The interdisciplinary forensic-medical, forensic-psychological and psychophytological approach will make it possible to provide the court with a complex forensic expertise.

    This study adds to the small body of research on home invasion by describing the circumstances surrounding home invasions that resulted in the death of a resident. The 2 most common types of home invasion homicides (HIHs) involved "drug ripoffs" and robberies of older adults for money and property. The study also examined subsequent rule-violating behavior of 132 HIH inmates while incarcerated. The rate of rule violations among HIH inmates was similar to a broader cohort of incarcerated homicide offenders. A logistic regression model identified variation in assaultive prison behavior based on some routine predictors (age, education, race, and prior imprisonment) and 2 associated with the crime (method of killing and age by gender of victims).

    This study investigates the convergent and predictive validity of behavioral crime scene indicators of sexual sadism in the context of rape and sexual homicide. The study is based on a sample of 268 adult males sentenced to a federal penitentiary in Canada. Information regarding crime scene behaviors was gathered from police records, a clinical interview with a psychologist, and a semistructured interview with the offender. A series of logistic regressions were performed to determine whether behavioral crime scene indicators of sexual sadism were associated with an official diagnosis of sexual sadism and were able to distinguish between sexual aggressors against women and sexual murderers. Findings suggest that several crime scene behaviors overlap with an official diagnosis of sexual sadism as well as being able to distinguish between sexual aggressors of women and sexual murderers. Importantly, the majority of crime scene behaviors associated with a clinical diagnosis of sexual sadism are not the same as those associated with sexual homicide.

    Nonsexually offending psychopaths (N = 32) were compared to sexual homicide perpetrators (N = 38) and nonviolent pedophiles (N = 39) on select Comprehensive System Rorschach variables (Exner et al., 1993). Results indicate similarities among the groups in pathological narcissism, formal thought disorder, and borderline level reality testing. Nonsexually offending psychopaths are distinguished by their lack of interest in and attachment to others and their seemingly conflict-free internal world. While both sexually deviant groups evidenced interest in others and appear to experience a very dysphoric internal world, the sexual homicide perpetrators are distinguished by high levels of obsessional thought and an inability to disengage from environmental stimuli. Pedophiles show significantly more characterological anger, which may stem from their general inadequacy, cognitive rigidness, less alloplastic (acting out) style, and their introversive inability to gratify their needs. Rorschach differences add to our understanding of sexual deviation and violence among these three groups.

    Psychological adaptation following homicide loss is challenged not only by the violent nature of the death itself but also by the bereaved's relationships with would-be supporters. Recruiting a sample of 54 African-American homicidally bereaved individuals, we examined perceived and actual support, the size of the support network, family versus non-family support, and number of negative relationships to gauge the role of social support in bereavement outcomes such as complicated grief, PTSD, and depression. Results of quantitative assessments revealed that size of available network, quantity of negative relationships, and levels of grief-specific support were correlated with bereavement outcome. Clinical implications and suggestions for future research on the role of social support in adaptation of African Americans to traumatic loss are discussed.

    Racial/ethnic residential segregation has been shown to contribute to violence and have harmful consequences for minority groups. However, research examining the segregation–crime relationship has focused almost exclusively on blacks and whites while largely ignoring Latinos and other race/ethnic groups and has rarely considered potential mediators (e.g., concentrated disadvantage) in segregation–violence relationships. This study uses year 2000 arrest data for California and New York census places to extend segregation–crime research by comparing the effects of racial/ethnic residential segregation from whites on black and Latino homicide. Results indicate that (1) racial/ethnic segregation contributes to both Latino and black homicide, and (2) the effects for both groups are mediated by concentrated disadvantage. Implications for segregation–violence relationships, the racial-invariance position, and the Latino paradox are discussed.

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

    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.

  7. Dependence of the firearm-related homicide rate on gun availability: a mathematical analysis.

    In the USA, the relationship between the legal availability of guns and the firearm-related homicide rate has been debated. It has been argued that unrestricted gun availability promotes the occurrence of firearm-induced homicides. It has also been pointed out that gun possession can protect potential victims when attacked. This paper provides a first mathematical analysis of this tradeoff, with the goal to steer the debate towards arguing about assumptions, statistics, and scientific methods. The model is based on a set of clearly defined assumptions, which are supported by available statistical data, and is formulated axiomatically such that results do not depend on arbitrary mathematical expressions. According to this framework, two alternative scenarios can minimize the gun-related homicide rate: a ban of private firearms possession, or a policy allowing the general population to carry guns. Importantly, the model identifies the crucial parameters that determine which policy minimizes the death rate, and thus serves as a guide for the design of future epidemiological studies. The parameters that need to be measured include the fraction of offenders that illegally possess a gun, the degree of protection provided by gun ownership, and the fraction of the population who take up their right to own a gun and carry it when attacked. Limited data available in the literature were used to demonstrate how the model can be parameterized, and this preliminary analysis suggests that a ban of private firearm possession, or possibly a partial reduction in gun availability, might lower the rate of firearm-induced homicides. This, however, should not be seen as a policy recommendation, due to the limited data available to inform and parameterize the model. However, the model clearly defines what needs to be measured, and provides a basis for a scientific discussion about assumptions and data.

    The comparative weighting of evidence in a criminal case can be a complicated task when the relevance or meaning of the evidence is disputed. An example of this complexity in seen in vehicular homicide investigations in which the identity of the driver (and thus the guilty party) is not clear. The discipline of Forensic Epidemiology, including the appropriate application of Bayes' Theorem (Bayes' Law) provides a systematic framework to bring clarity to the evaluation of such matters. Bayes' is a useful tool for the conditioning and quantification of probabilities associated with evidence in a vehicular homicide investigation. The authors present a case study in the application of Bayes' Theorem to the facts in a vehicular homicide investigation. An initial analysis of the crash dynamics in comparison with the injury pattern and ejection status of the surviving occupant versus that of the decedent suggested that the survivor was the driver. The results of the analysis were used as tests for guilt, with estimated true and false positive rates, which then formed the basis for a Bayesian calculation of the posterior probability of the survivor's guilt given the evidence. As a result of the Bayesian analysis described herein, it was determined that the survivor was 19 times more likely to have been the driver, in comparison with the decedent. This ratio far exceeded the suggested threshold of 10:1 for establishing the guilt of the survivor beyond a reasonable doubt. When used properly, Bayes' Theorem can offer definitive insight in the investigation and prosecution of vehicular homicide cases.

    BACKGROUND: Delinquent youth are at risk for early violent death after release from detention. However, few studies have examined risk factors for mortality. Previous investigations studied only serious offenders (a fraction of the juvenile justice population) and provided little data on females. METHODS: The Northwestern Juvenile Project is a prospective longitudinal study of health needs and outcomes of a stratified random sample of 1829 youth (657 females, 1172 males; 524 Hispanic, 1005 African American, 296 non-Hispanic white, 4 other race/ethnicity) detained between 1995 and 1998. Data on risk factors were drawn from interviews; death records were obtained up to 16 years after detention. We compared all-cause mortality rates and causes of death with those of the general population. Survival analyses were used to examine risk factors for mortality after youth leave detention. RESULTS: Delinquent youth have higher mortality rates than the general population to age 29 years (P < .05), irrespective of gender or race/ethnicity. Females died at nearly 5 times the general population rate (P < .05); Hispanic males and females died at 5 and 9 times the general population rates, respectively (P < .05). Compared with the general population, significantly more delinquent youth died of homicide and its subcategory, homicide by firearm (P < .05). Among delinquent youth, racial/ethnic minorities were at increased risk of homicide compared with non-Hispanic whites (P < .05). Significant risk factors for external-cause mortality and homicide included drug dealing (up to 9 years later), alcohol use disorder, and gang membership (up to a decade later). CONCLUSIONS: Delinquent youth are an identifiable target population to reduce disparities in early violent death. PMID:24936005

    This retrospective study from Western Norway is based on the cases of 196 homicide victims from 1985 to 2009. The median age of the victims was 35 years, in both genders. Within the cases, 113 of the victims were male and 83 female, 28 victims were under the age of 18, and 19 victims were not native Norwegians. Ethanol was detected in the blood of a higher proportion of male compared to female victims, whereas a higher proportion of female compared to male victims had both illegal/legal drugs detected in their blood. Most perpetrators were male. Men were most often killed by an acquaintance, women by their present or former intimate partner. In 14 cases of intimate partner homicide the perpetrator committed suicide after killing their female partner. The dominant scene of crime was private homes. Most victims were killed by blunt force, sharp force or gunshot. The head was the body region most often injured in the homicide victims. Female victims were more often killed by manual strangulation than male victims.

    Prior research suggests that homicide cases involving familial offenders and victims are subject to a "domestic discount" that reduces sentencing severity. However, the operation of a domestic discount in regard to death penalty sentencing has been rarely examined. The current research uses a near-population of jury decisions in capital murder trials conducted in North Carolina from 1991 to 2009 (n = 800), and a series of logistic regression analyses to determine whether there is (a) a direct effect between offender-victim relationship (e.g., domestic, friend/acquaintance, and stranger) and jury decision making, and/or (b) whether domestic offender-victim relationship (as well as other offender-victim relationships) moderates the effect of legal and extralegal case characteristics on jury assessment of the death penalty. Our findings revealed no empirical support for a "domestic discount" whereby juries are less likely to impose death sentences in cases involving domestic homicides. However, substantial differences in predictors of death sentencing were found across offender-victim dyads; most notably, domestic homicide cases demonstrated the most legalistic model of jury decisions to impose death sentences.

  13. Taxing sin and saving lives: Can alcohol taxation reduce female homicides?

    With costs exceeding $5.8 billion per year, violence against women has significant ramifications for victims, their families, the health care systems that treat them, and the employers who depend on their labor. Prior research has found that alcohol abuse contributes to violence against both men and women, and that stringent alcohol control policies can reduce alcohol consumption and in turn some forms of violence. In this paper, we estimate the direct relationship between an important alcohol control measure, excise taxes, and the most extreme form of violence, homicide. We use female homicide rates as our measure of severe violence, as this measure is consistently and accurately reported across multiple years. Our results provide evidence that increased alcohol taxes reduce alcohol consumption and that reductions in alcohol consumption can reduce femicide. Unfortunately, a direct test of the relationship does not have the power to determine whether alcohol taxes effectively reduce female homicide rates. We conclude that while alcohol taxes have been shown to effectively reduce other forms of violence against women, policy makers may need alternative policy levers to reduce the most severe form of violence against women.

    When one parent kills the other, children are confronted with multiple losses, involving their attachment figures and their direct living environment. In these complex situations, potentially drastic decisions are made, for example, regarding new living arrangements and contact with the perpetrating parent. We aimed to synthesize the empirical literature on children's mental health and well-being after parental intimate partner homicide. A systematic search identified 17 relevant peer-reviewed articles (13 independent samples). We recorded the theoretical background, methodology, and sample characteristics of the studies, and extracted all child outcomes as well as potential risk and protective factors. Children's outcomes varied widely and included psychological, social, physical, and academic consequences (e.g., post-traumatic stress, attachment difficulties, weight and appetite changes, and drops in school grades). Potential risk and protective factors for children's outcomes included 10 categories of pre-, peri-, and post-homicide characteristics such as cultural background of the family, whether the child witnessed the homicide, and the level of conflict between the families of the victim and the perpetrator. We integrated the findings into a conceptual model of risk factors to direct clinical reflection and further research.

    The incidence and severity of acute respiratory disease was studied in families in three New York communities with different ambient levels of SO/sub 2/ and particulate air pollution. Upper, lower, and total respiratory disease rates in fathers, mothers, and school children tended to be higher in the communities with higher pollution levels. Similar higher rates, however, were not observed among preschool children. Regression analyses were used to adjust rates for socioeconomic status, parental smoking, chronic bronchitis in parents, and possible indoor pollution resulting from the use of a gas stove for cooking. After these adjustments the community differences were still significant (P < .01), for school children. The indoor pollution related to gas stoves was a significant covariate among children. The effects of smoking were inconsistent. It was not possible to attribute the higher rates observed to any specific pollutant, since both SO/sub 2/ and particulate matter levels were higher in the high pollution communities, nor was it possible to attribute the excesses to current levels of exposure or to a residual effect of previous higher exposure concentrations. The fact that young children did not follow the patern suggests the latter. It was concluded, however, that current or previous exposures to the complexity of air pollutants in New York City was at least partially responsible for increased incidences of acute respiratory disease.

    The authors made an attempt to verify if a coconut can be used as a model of human skull to determine the homicide weapon. During our experiment 27 strike attempts were performed with the use of 9 different tools. Among them there were authentic murder weapons and instruments which had been used in similar experiments conducted on human skulls in 1955. Depending on the size of an area in contact with a coconut, weapons caused dents corresponding to the shape of a weapon, irregular fractures or long linear cracks. Our results have shown that coconut can be used as an inexpensive screening model of human skull, but only to determine fractures made by tools with small striking surface.

    A longitudinal entomological and epidemiological study was conducted in five localities of southern Venezuela between January 1999 and April 2000 to determine the abundance, biting behaviour and parity of anopheline mosquitoes (Diptera: Culicidae) in relation to climate variables and malaria incidence. A total of 3685 female anopheline mosquitoes, representing six species, were collected. The most abundant species were Anopheles marajoara Galvão & Damasceno (60.7%) and Anopheles darlingi Root (35.1%), which together represented 95.8% of the total anophelines collected. Abundance and species distribution varied by locality. Malaria prevalence varied from 12.5 to 21.4 cases per 1000 population. Transmission occurred throughout the year; the annual parasite index (API) for the study period was 813.0 cases per 1000 population, with a range of 71.6-2492 per 1000 population, depending on locality. Plasmodium vivax (Grassi & Feletti) (Coccidia: Plasmodiidae) accounted for 78.6% of cases, Plasmodium falciparum (Welch) for 21.4% and mixed infections (Pv+Pf) for < 0.1%. Anopheles marajoara and An. darlingi were more abundant during the rainy season (April-September). There was no significant correlation (P > 0.05) between mosquito abundance and rainfall. Correlations between malaria incidence by parasite species and mosquito abundance were not significant (P > 0.05). Monthly parous rates were similar for An. marajoara and An. darlingi throughout the year, with two peaks that coincided with the dry-rainy transition period and the period of less rain. Peaks in the incidence of malaria cases were observed 1 month after major peaks in biting rates of parous anophelines. Anopheles darlingi engages in biting activity throughout the night, with two minor peaks at 23.00-00.00 hours and 03.00-04.00 hours. Anopheles marajoara has a different pattern, with a biting peak at 19.00-21.00 hours and 76.6% of biting occurring before midnight. Although both vectors bite indoors and outdoors

    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.

    Homicide-suicides (HS) are relatively infrequent events. Yet, they are of great concern because they often result in the death of family members, young children, and cause additional morbidity, family disruption and childhood psychological trauma. The aims of our study were (a) to examine the sociodemographic, clinical, and autopsy characteristics of HS in Paris and its suburbs from 1991 through 1996, and (b) to analyze the psychodynamic determinants leading up to the onset of HS. Our findings are compared with those obtained in other international studies. For the purpose of the present study. HS was defined as a violent event in which an individual committed homicide and subsequently committed suicide within a few hours. The main results are as follows. During the six-year study period, 56 HS involving 133 victims were investigated at the Institute of Forensic Medicine of Paris. Seventeen events occurred in Paris and 39 in its suburbs. Paris has a population of approximately 2,200,000 while its suburbs are home to another 8,5000,000. Of the 56 offenders, 48 (85%) were males. The mean age of offenders was 51 years in males (range, 24 to 83) and 40.5 years in females (range, 33 to 56). In 45 events (80%), the offenders used a gun for both the homicide and suicide. A knife was used in only 4 murders, strangulation in 4 other cases, with poisoning, arson, or beating occurring in one case each. In 9 cases, the offender used a different weapon for homicide and suicide. Among firearms, handguns were more likely to be used (26 cases) than shotguns (6 cases) or rifles (13 cases). In 40 cases the offender killed one victim, in 11 cases 2 victims, and in 5 cases 3 victims. The homicide victims consisted of 34 children (21 boys), mean age 8 years (range, 1 to 16), 29 spouses (26 females), 2 girlfriends, 10 strangers, and 2 relatives. Five pets were killed. HS were most likely to be committed in the home. A suicide note was found near the victims in 29 cases (50% of events

    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

    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.

    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.

  6. A mimic of sexually-motivated homicide: insect stings and heat exhaustion in a forest.

    We report the case a woman who was found dead in a forest. The body was nude and the position of the body suggested a sexually motivated homicide. We concluded that death was not related to homicide, but was related to the conjunction of environmental factors, including insect stings, and acute psychosis. A medicolegal death investigation with postmortem examination was undertaken to determine cause of death. At the scene, the body was supine with legs spread apart and the knees flexed, exposing the external genitalia. There were multiple apparent bruises on the body and neck. At autopsy, based on macroscopic and microscopic examination, the apparent bruises were found to be hemorrhagic insect bites. No significant injuries were present and no semen was found. Death appeared to be related to heat exhaustion and innumerable insect stings. Investigation of the medical history revealed longstanding schizoaffective disorder with episodic psychotic decompensations. In the past, during an acute psychotic episode the decedent removed her clothing and ran wildly in a forest, until she was rescued in a state of exhaustion and marked agitation, and taken to hospital for treatment. We concluded that the same circumstances had been repeated but with a fatal outcome. This case is an example of a mimic of sexually-motivated homicide and is a reminder to forensic pathologists to avoid tunnel vision. We need to be skeptical of the allure of common sense based on first impressions of the scene and the body. Forensic pathologists must be unafraid to scientifically explore improbable, but true, alternate explanations.

    OBJECTIVE: The homicide rate for children and adolescents in Recife, Brazil, mostly caused by firearms, is one of the highest that has been reported. The present case-control study was designed to identify factors that were potentially modifiable through preventive interventions. METHODS: Cases were 255 homicide victims under 20 years of age, who had died in 1997 and been identified at the Institute of Forensic Medicine, Police Department, Recife, and whose relatives were interviewed by two community health workers when they claimed the corpse. The 255 controls were neighbours of the cases, paired by age and sex to them, and identified within one week of identification of each case, and whose relatives were interviewed by a third community health worker. FINDINGS: The overall homicide rate in Recife for under-20-year-olds in 1997 was 49 per 100,000; among males aged 15-19 years it was 324 per 100,000. Firearms were responsible for 97% of deaths. After multivariate logistic regression, history of personal police records (odds ratio (OR) = 18.65; 95% confidence interval (CI) = 1.91-182.50), use of illicit drugs (OR = 7.48; 95% CI = 1.86-30.17), tap water at home (OR = 7.30; 95% CI = 1.80-29.59), and maternal age at birth over 26 years (OR = 3.98; 95% CI = 1.79-8.84) were identified as risk factors, while higher education (OR = 0.22; 95% CI = 0.11-0.43), religious practice (OR = 0.25; 95% CI = 0.10-0.65), and presence of the father in the household (OR = 0.28; 95% CI = 0.09-0.81) were protective factors. CONCLUSION: Public health authorities should plan preventive interventions based on the findings of this study and should control the acquisition, possession and carrying of firearms. PMID:11217662

    We performed analyses of data on 292 homicides by poisoning in the United States. The data from the Uniform Crime Reports (UCR) 1980 through 1989, involved cases of one poisoned victim and one poisoning offender. Demographic factors analyzed for each victim and offender include age, gender, race, relationship of victim to offender, major category of poison, month, year, geographic location, and crime classification. The goal of this study is to identify homicidal poisoner demographics that could assist forensic scientists and law enforcement personnel in their criminal investigations and to serve as the foundation for a more formal investigative analysis of this kind of subtle killer.

  9. Violence among young men: the importance of a gender-specific developmental approach to adolescent male suicide and homicide.

    Suicide and homicide are much more commonly committed by adolescent males than females. Herein, a proposal in favor of gender-specific understanding and approach to these violent behaviors is presented. Social and healthcare service system factors, including issues of male adolescents' access to care and help-seeking behaviors, are reviewed alongside the epidemiology of adolescent suicide and homicide as a transition into a detailed discussion of the putative biological factors at play. An emphasis upon the male androgen testosterone organizes the discussion. Behavioral manifestations of this brain-based organizational model are presented with a focus on impulsivity, aggression, and externalizing dysregulated emotionality. Treatment considerations and implications are developed.

    This paper estimates the health dimension of the welfare cost of homicides in Brazil incorporating age, gender, educational, and regional heterogeneities. We use a marginal willingness to pay approach to assign monetary values to the welfare cost of increased mortality due to violence. Results indicate that the present discounted value of the welfare cost of homicides in Brazil corresponds to roughly 78% of the GDP or, in terms of yearly flow, 2.3%. The analysis also shows that reliance on aggregate data to perform such calculations can lead to biases of around 20% in the estimated social cost of violence.

    As the investigation and prosecution of sexual homicide cases becomes increasing complex, law enforcement agencies are utilizing alternative avenues of investigative assistance. In 2004, the Oakland County, Michigan Sheriff's Office was faced with the horrific sexual assault and murder of an elderly woman. Although familiar with violent crime, this extremely violent and unusual case motivated the police to enlist the help of forensic scientists and FBI violent crime researchers to assist their investigation. This partnership led to the successful investigation and prosecution of the offender and serves as a model for law enforcement agencies willing to consider using additional available resources in order to successfully resolve unusual and extraordinarily violent sexual crimes.

  12. Criminal homicide in northern Sweden 1970-1981: alcohol intoxication, alcohol abuse and mental disease.

    All cases of criminal homicide in northern Sweden between 1970-81 were studied, 71 cases altogether (64 offenders). Homicide was a rare event and more infrequent compared with Sweden as a whole. The offenders were predominantly males, ages 20 to 40. Half of the victims were females. Mutual intoxication was a feature in 44% of the cases and in 34% both participants were sober. The majority of the victims were related by blood or marriage to the offender. Sharp instruments, blunt instruments and use of firearms were, in this order, the most common methods of killing. Almost one-third of the offenders had no former conviction, minor trespasses excluded. Sixty-three percent of the offenders had previously been subjected to psychiatric care, 31% were considered mentally diseased at the trial and another 22% had also a coexisting abuse or personality disorder. Three-quarters of the offenders were transferred to closed psychiatric care. Alcohol abuse and alcoholism were prevalent among 30% of the offenders and another 27% were also mentally diseased or had a personality disorder. The shares of mentally diseased and abusers/alcoholics outnumbered the prevalence of these conditions in the general population as well as in many international studies. Ten subjects committed suicide before trial; these persons were relatively more often sober at the act and fewer were alcoholics. Eight had previously received psychiatric treatment. They were more prone to kill a member of their nuclear family. Only two subjects had a previous criminal record; both concerned convictions of manslaughter. Nineteen offenders were sober at the act; 15 of these were mentally diseased. The sober offenders hardly ever attacked a person outside their family. Their motives were frequently premeditated. The killings were usually by quick, certain methods, such as firearms. No sober offender attacked an intoxicated person. The sober offenders usually had no criminal records and the homicides were often

    Bovine brucellosis due to Brucella abortus infection causes significant reproductive and production losses in cattle and is a major zoonosis. Eradication of this disease has proved difficult to achieve in Portugal where it still occurs in some regions despite an ongoing national eradication programme. In 2004, the Alentejo region, a major cattle producing area, reported one of the highest levels of bovine brucellosis in the country, especially in one divisional area. In that area, bovine brucellosis was particularly problematic in a holding of ten herds, the largest extensive cattle unit in the country, which remained infected despite an extensive test-and-slaughter programme and depopulation of five herds. A 5-year programme of RB51 vaccination with biannual test-and-slaughter was thus implemented in 2004. The apparent animal seroprevalence decreased from 19% (646/3,400) to 3% (88/2930) on the third herd-level test and remained below 0.8% (27/3324) after the fourth test. After the tenth test, the holding had a prevalence of 0.1% (2/2332) and only one herd remained positive with a within-herd prevalence of 1.1% (2/177). The results were compared to all other herds (n = 10) in the divisional area that were also persistently infected but were subject only to test-and-slaughter before being depopulated. In these herds, the strategy of test-and-slaughter did not reduce the prevalence, which remained significantly higher than the vaccinated group (median = 0.48% and 8.5% in vaccinated versus non-vaccinated herds; Wilcoxon rank sum test; P < 0.01). The success of this pilot programme in continental Portugal provided a valuable case study to the official veterinary services by illustrating the value of RB51 vaccination with parallel testing and improved biosecurity as a comprehensive and sustainable strategy for bovine brucellosis control in persistently infected herds.

    The link between the high incidence of lung cancer and harmful pollutants emitted by local coal combustion in Xuanwei, Yunnan province, China, has been a focus of study since the 1980s. However, the mechanisms responsible for the high lung cancer rate remain unclear, necessitating further study. Since a close relationship between ambient air particle pollution and respiratory diseases exists, we sampled size-resolved ambient particles from the atmosphere of Xuanwei. In our indoor experiment, cutting-edge methods, including scanning electron microscopy coupled with energy dispersive X-ray detection (SEM/EDX), particle-induced X-ray emission (PIXE), electronic paramagnetic resonance (EPR) and the cell-free DCFH-DA assay, were employed to investigate the physicochemical properties, the potential to generate free radicals and the oxidative potential of ambient coarse (diameter, 1.8-10 μm), fine (diameter, 0.1-1.8 μm), and ultrafine (diameter, <0.1 μm) particles. We found the total mass concentrations of the size-resolved particles collected in spring were higher than that in early winter. Mass percentage of fine particles accounted for 68% and 61% of the total particulate mass in spring and in early winter samples, respectively, indicating that fine particles were the major component of the Xuanwei ambient particulate matters. On the other hand, the results of SEM/EDX analysis showed that the coarse particles were dominated by minerals, the fine particles by soot aggregates and fly ashes, and the ultrafine particles by soot particles and unidentified particles. Our PIXE results revealed that crustal elements (Ca, Ti Si, Fe) were mainly distributed in coarse particles, while trace metals (Cr, Mn, Ni, Cu, Zn, Pb) dominated in the fine particle fraction, and S, a typical element emitted by coal combustion, mainly resided in fine particles collected from the winter atmosphere. EPR results indicated that the magnitude of free radical intensity caused by size

    No follow-up studies exist on how minors who commit sexual homicides adjust once released back into the community. This is an important question given the extreme nature of their crimes, lack of recidivism data, and the expectation that one-half of them will be freed from prison by mid-life. Likewise, no studies exist on the role our culture's pervasive media violence plays in these offenses. This report describes a 13-year-old boy who committed a witnessed media violence-inspired sexual homicide. Follow-up information is provided on his community adjustment as an adult four years after release from prison. He had multiple indicators of brain dysfunction, and watched a "slasher" film just before committing the blitz style crime upon a female neighbor. Media violence literature is reviewed--against a backdrop of developmental abnormalities, neuropsychiatric vulnerabilities, family dysfunction, and mental illness. This case illustrates how the confluence of such variables, combined with the tinder of erotic screen violence, may lead to sexual murder.

  19. Patterns of intimate partner homicide suicide in later life: Strategies for prevention

    Intimate partner homicide suicide (IPHS) constitutes the most violent domestic abuse outcome, devastating individuals, families, neighborhoods and communities. This research used content analysis to analyze 225 murder suicide events (444 deaths) among dyads with at least one member 60 or older. Data were collected from newspaper articles, television news transcripts, police reports and obituaries published between 1999 and 2005. Findings suggest the most dangerous setting was the home and the majority of perpetrators were men. Firearms were most often employed in the violence. Relationship strife was present in some cases, but only slightly higher than the divorce rate for that age group. Illness was cited in just over half of the cases, but 30% of sick elderly couples had only a perpetrator who was ill. Evidence of suicide pacts and mercy killings were very rare and practitioners are encouraged to properly investigate these events. Suicidal men in this age range must be recognized as a potential threat to others, primarily their partner. Homicide was sometimes the primary motive, and the perpetrators in those cases resembled the “intimate terrorist.” Victims in those cases were often terrorized before the murder. Clinicians are educated about the patterns of fatal violence in later life dyads and provided with strategies for prevention. PMID:18044194

  1. The motivation behind serial sexual homicide: is it sex, power, and control, or anger?

    2006-07-01

    Controversy exists in the literature and society regarding what motivates serial sexual killers to commit their crimes. Hypotheses range from the seeking of sexual gratification to the achievement of power and control to the expression of anger. The authors provide theoretical, empirical, evolutionary, and physiological support for the argument that serial sexual murderers above all commit their crimes in pursuit of sadistic pleasure. The seeking of power and control over victims is believed to serve the two secondary purposes of heightening sexual arousal and ensuring victim presence for the crime. Anger is not considered a key component of these offenders' motivation due to its inhibitory physiological effect on sexual functioning. On the contrary, criminal investigations into serial sexual killings consistently reveal erotically charged crimes, with sexual motivation expressed either overtly or symbolically. Although anger may be correlated with serial sexual homicide offenders, as it is with criminal offenders in general, it is not causative. The authors further believe serial sexual murderers should be considered sex offenders. A significant proportion of them appear to have paraphilic disorders within the spectrum of sexual sadism. "sexual sadism, homicidal type" is proposed as a diagnostic subtype of sexual sadism applicable to many of these offenders, and a suggested modification of DSM criteria is presented.

    The construct of psychopathy is essential in explaining criminal behavior, but unfortunately the empirical research on psychopathy in women has been inconsistent. In this study the underlying structure of psychopathy in women was examined by testing the two-factor model by Hare (2003) and the three-factor solution by Cooke and Michie (2001) using confirmatory factor analysis. We replicated the study by Warren et al. (2003) using a nationwide sample of 97 female homicide offenders in order to facilitate the comparison of results. The prevalence of psychopathy in the present study was 9.3% with a cut-off of >or=30 and 21.6% with a cut-off of >or=25. The best fit for the data out of the tested models was the three-factor model with six testlets. The two-factor model proved to be too simple a model for the female homicide data. The findings regarding comorbidity of psychopathy with personality disorders show that the concept of psychopathy includes diagnostic criteria of several personality disorders, but further research is needed to establish a possible superordinate dimension. Further research on the PCL-R and putative gender differences in the expression of psychopathy in women and men as well as on the putative impact of cultural differences on the instrument is clearly needed.

    To examine the predictive accuracy of four well established risk assessment instruments (PCL-R, HCR-20, SVR-20, and Static-99) in an important subgroup of sexual offenders, these instruments were assessed retrospectively based on information from forensic psychiatric court reports in a sample of 90 released male sexual homicide offenders (out of an original sample of 166) in Germany. Follow-up information about criminal reconvictions after release were obtained from the federal criminal records. Total scores as well as subscales and single items of these risk assessment instruments did not predict sexual recidivism, and only some of them had moderate predictive power regarding nonsexual violent recidivism. Possible explanations for these unexpected results are the retrospective study design with missing information about influences during the long duration of detention and time after release, the small sample size as well as the possibility that the risk assessment instruments investigated were valid for general sex offender samples, but not for the particular subgroup of offenders with sexually motivated homicides.

    Homicide rates vary widely across and within different continents. In order to address the problem of violence in the world, it seems important to clarify the sources of this variability. Despite the fact that income inequality and imprisonment seem to be two of the most important determinants of the variation in homicide rates over space and time, the concomitant effect of income inequality and imprisonment on homicide has not been examined. The objective of this cross-sectional ecological study was to investigate the association of income inequality and imprisonment with homicide rates among Developed (OECD), South and Central American countries. A novel index was developed to indicate imprisonment: the Impunity Index (the total number of homicides in the preceding decade divided by the number of persons in prison at a single slice in time). Negative binomial models were used to estimate rate ratios of homicides for young males and for the total population in relation to Gini Index and Impunity Index, controlling for infant mortality (as a proxy for poverty levels), Gross Domestic Product per-capita, education, percentage of young males in the population and urbanization. Both low income inequality and low impunity (high imprisonment of criminals) were related to low homicide rates. In addition, we found that countries with lower income inequality, lower infant mortality (less poverty), higher average income (GDP per-capita) and higher levels of education had low impunity. Our results are compatible with the hypothesis that both low income inequality and imprisonment of criminals, independent of each other and of other social-structural circumstances, may greatly contribute to the reduction in homicide rates in South and Central American countries, and to the maintenance of low levels of homicides in OECD countries. The Impunity Index reveals that countries that show greater commitment to education and to distribution of income also show greater commitment to

    The differential diagnosis between self-inflicted and nonself-inflicted, suicidal and homicidal, injuries is difficult or impossible in many cases and, above all, cannot be made on the basis of information obtained solely from the autopsy or the medicolegal clinical examination. The purpose of this study is to analyze the literature on suicidal and homicidal sharp force injuries and identify the relevant parameters that may help differentiate between suicidal and homicidal deaths. To achieve this goal, a review of 595 potentially relevant articles was performed. After excluding the nonrelevant papers by screening the titles, all abstracts were reviewed, and articles meeting the inclusion criteria underwent a full-text review. The following parameters were compiled into a table: number of cases, localization of the injuries, and number of injuries. The data were statistically analyzed and compared with those available in the forensic literature. On the basis of the heterogeneity of data revealed by the present review, a simple and short checklist of the parameters that should be included when reporting suicides and homicides by sharp force has been proposed.

    We reviewed all 87 deaths from the Happy Land Social Club fire. All deaths were due to smoke inhalation. The carboxyhemoglobin (COHb) concentrations ranged from 37 to 93% with a mean of 76.5%. The vast majority (97%) of the decedents had a COHb concentration over 50%. Cyanide blood concentrations ranged from 0 to 5.5 mg/L with a mean of 2.2 mg/L. Nine decedents had no cyanide detected, and seven had cyanide concentrations of less than 1 mg/L. Fewer than one third of the decedents had thermal injuries, and most were partial thickness burns involving less than 20% body surface area. Ethanol was detected in 72% of decedents with a range of 0.01 to 0.29 g% and a mean blood concentration of 0.11 g%. Cocaine or cannabinoid use was identified in 9% of the decedents. All decedents were visually identified, and all had soot in the airway extending to the major bronchi. Carboxyhemoglobin concentrations corresponded well with deaths from smoke inhalation. Cyanide concentrations did not correspond with the extent of smoke inhalation, and the role of cyanide in contributing to these deaths is doubtful. Hydrogen chloride inhalation, as evidenced by comparison of the pH of tracheal mucosa to controls, was not a factor.

    Chronic kidney disease of non-traditional causes is epidemic in Central America, Southern Mexico and other regions of the world such as Sri Lanka, where the origin of the illness is attributed to exposure to agrochemicals and arsenic in soils and groundwater. In Central America, several causes have been suggested for this illness including: high ambient temperatures and chronic dehydration, and toxic effects of agrochemicals. Previous research using step-wise multivariate regression in El Salvador found statistically significant correlation between the spatial distribution of the number of sick people per thousand inhabitants and the percent area cultivated with sugar cane, cotton, and beans, and maximum ambient temperature, with sugar cane cultivation as the most significant factor. This study aims to investigate the possible effects of agricultural activities in the occurrence of this illness looking at heavy metal, arsenic and pesticide contamination in soil, water and sediments of a community located in Bajo Lempa region (Ciudad Romero, El Salvador) and heavily affected by this illness. The Bajo Lempa region is close to Lempa River delta, in the Pacific coast. Ground and surface water, sediment and soil samples were collected in the village where the patients live and in the agricultural areas where they work. With respect to the heavy metals, lead and cadmium where detected in the soils but below the standards for cultivated soils, however, they were not detected in the majority of surface and groundwater. Of the inorganic contaminants, arsenic was present in most soil, sediments, and water samples with some concentrations considerable higher than the standards for cultivated lands and drinking water. Statistically different concentrations in soils were found for the village soils and the cultivated soils, with arsenic higher in the cultivated soils. For the pesticides, results show a significant pollution of soil and groundwater of organochlorine pesticides

    In this study, we aimed to describe the social and clinical characteristics and offense details in a sample of people with schizophrenia convicted of homicide in the eastern region of Turkey. This study was performed in Elazig Mental Hospital between November 2004 and May 2007. We included 43 men and 6 women with schizophrenia convicted of homicide who were hospitalized in the forensic psychiatry unit for compulsory treatment. Preset data recording forms were used. The first part of the forms contained questions regarding the age, sex, marital status, residence, educational status, and occupation of the patients. The second part of the forms included questions about some clinical features of patients with schizophrenia: the presence of schizophrenia in any family member, duration of the disease, subtype of schizophrenia, previous contact with mental health services, types of antipsychotics (first and last drug used), and adherence to antipsychotic medication. The third part of the forms dealt with alcohol-substance abuse and features of the victim (sex of the victim and whether the victim was a stranger, partner, or an ex-partner in the family or an acquaintance). The mean +/- SD age of our patients was 36.98 +/- 10.07 years, and 55.1% of the patients were unmarried. In our sample, 42.9% of the patients were primary school graduates and 75.5% were unemployed. Of the perpetrators, 14.3% never had contact with mental health services. However, 85.7% of patients had previous contact with mental health services. We found that 85.7% of the patients were paranoid subtype and 85.7% were not using their medication regularly and that treatment compliance was considerably low.

    The authors provide an overview of methods for summarizing social disparities in health using the example of lung cancer. They apply four measures of relative disparity and three measures of absolute disparity to trends in US lung cancer incidence by area-socioeconomic position and race-ethnicity from 1992 to 2004. Among females, measures of absolute and relative disparity suggested that area-socioeconomic and race-ethnic disparities increased over these 12 years but differed widely with respect to the magnitude of the change. Among males, the authors found substantial disagreement among summary measures of relative disparity with respect to the magnitude and the direction of change in disparities. Among area-socioeconomic groups, the index of disparity increased by 47% and the relative concentration index decreased by 116%, while for race-ethnicity the index of disparity increased by 36% and the Theil index increased by 13%. The choice of a summary measure of disparity may affect the interpretation of changes in health disparities. Important issues to consider are the reference point from which differences are measured, whether to measure disparity on the absolute or relative scale, and whether to weight disparity measures by population size. A suite of indicators is needed to provide a clear picture of health disparity change.

    Reintegrative shaming theory (RST) argues that social aggregates characterized by high levels of communitarianism and nonstigmatizing shaming practices benefit from relatively low levels of crime. We combine aggregate measures from the World Values Survey with available macro-level data to test this hypothesis. Additionally, we examine the extent to which communitarianism and shaming mediate the effects of cultural and structural factors featured prominently in other macro-level theoretical frameworks (e.g., inequality, modernity, sex ratio, etc.). Findings provide some support for RST, showing homicide to vary with societal levels of communitarianism and informal stigmatization. However, while the effects of modernity and sex ratio were mediated by RST processes, suppression was indicated for economic inequality. Implications for theory and research are discussed.

    Disenfranchised grief is experienced when a mourner's grief response is socially invalidated, unacknowledged, or discouraged. When the circumstances of death or the emotional reactions of the griever violate social norms, empathic failures can occur within the bereaved individual's support systems. This study used conventional content analysis, an intensive and inductive qualitative research method, to analyze the experience of one African American woman who lost her only son to homicide, a particularly distressing and marginalized form of loss. Results elucidate both the empathic failings and resiliencies within the social systems of this griever and emerged from the perspectives offered by the bereaved mother and her primary supporter. Clinical implications and suggestions for future research are discussed.

    Developmental research on social influences on adolescents can guide practices aimed to prevent homicidal youth violence. School shootings have repeatedly raised questions about the contributory role of bullying and entertainment violence, how news media publicity might produce copycat crimes, and whether stiffer criminal sanctions might have a deterrent effect. This article presents the thoughts and recommendations of a group of experts on these topics summarizing the current knowledge base. In brief, bullying reduction programs may be a useful early prevention effort. Television and video games with violent themes can encourage aggressive behavior, but these media can be used to teach more prosocial behavior as well. The potential copycat effects of highly publicized crimes might be diminished with more restrained reporting, although more research is needed. Finally, there is substantial evidence that increased criminal sanctions for youthful offenders have not had a deterrent effect.

  17. The impact of New York City's 1975 fiscal crisis on the tuberculosis, HIV, and homicide syndemic.

    In 1975, New York City experienced a fiscal crisis rooted in long-term political and economic changes in the city. Budget and policy decisions designed to alleviate this fiscal crisis contributed to the subsequent epidemics of tuberculosis, human immunodeficiency virus (HIV) infection, and homicide in New York City. Because these conditions share underlying social determinants, we consider them a syndemic, i.e., all 3 combined to create an excess disease burden on the population. Cuts in services; the dismantling of health, public safety, and social service infrastructures; and the deterioration of living conditions for vulnerable populations contributed to the amplification of these health conditions over 2 decades. We estimate that the costs incurred in controlling these epidemics exceeded 50 billion US dollars (in 2004 dollars); in contrast, the overall budgetary saving during the fiscal crisis was 10 billion US dollars. This history has implications for public health professionals who must respond to current perceptions of local fiscal crises.

    Forensic investigations have been embraced in many developed countries to help investigate homicidal cases in their legal system amongst others. It is however still in infancy state in many developing countries, including Nigeria, making the use of this very vital tool very limited to prosecute cases. Some of the reasons include the low knowledge base of the investigating officers, to the dearth of Forensic personnel and the inability to use the findings to prosecute the offenders. The few cases where proper investigation is done, anatomic pathologists and sometimes medical officers are usually called to provide the forensic evidence. Often this involves exhumation of corpse. Exhumation of corpses for death investigation is not a common occurrence in Nigeria and we present the findings seen in these cases.

    As part of a research study undertaken in the period 2003-2011 to understand situations of homicidal violence based in perceptions regarding the act of violence and the surrounding context, we reflect on the meaning of "invisible bourdaries" in the neighborhoods of Medellin (Colombia). Using a qualitative approach that combines documentary sources and interviews, the experiences of 8 participants are analyzed. In the primary results we can see how control over neighborhoods is exercised by different actors through bourdaries not visible to ordinary people. Nevertheless, around these lines people are recruited and controlled and strategies to illegally generate economic resources and to regulate the cultural and social activities of inhabitants are consolidated, thus affecting the social dynamics and imaginary of the neighborhood. In this way, the territories, friendships, and affects of young victims – who are not linked to illegal groups and/or do not have "information" – and of defenseless older adults are controlled.

    Interest in psychiatrists' professional liability in Italy has increased in recent years because of the number of medical malpractice claims. Professional liability for failure to prevent violent behaviour by psychiatric patients is particularly debated. This study describes three Italian cases in which health professionals - physicians and nurses - were found guilty of manslaughter for murders committed by psychiatric patients. Examination of the cases focuses on claims of malpractice, patients' characteristics, the circumstances of the homicide and the reasons for the court's judgment. In particular, the predictability of violent behaviour and the concept of causal links are examined in detail. The cases provide an opportunity for a study of comparative jurisprudence. The topics discussed are relevant not only to practicing psychiatrists but also to experts assessing medical liability in cases of criminal acts committed by psychiatric patients.
