  13. Causality in criminal forensic and in civil disability cases: Legal and psychological comparison.

    PubMed

    Young, Gerald

    2015-01-01

    Causality (or causation) is central to every legal case, yet its underlying philosophical, legal, and psychological definitions and conceptions vary. In the criminal context, it refers to establishing the responsibility of the perpetrator of the criminal act at issue in terms of the person's mental state (mens rea), and whether the insanity defense applies. In the forensic disability and related context, it refers to whether the index event is a material or contributing cause in the multifactorial array that led to the psychological condition at issue. In both the criminal and tort contexts, the legal test is a counterfactual one. For the former, it refers to whether the outcome involved would have resulted absent the act (e.g., in cases of simultaneous criminal lethal action, which one is the but-for responsible one). For the latter, it concerns whether the claimed psychological condition would be present only because of the incident at issue. The latter event at issue is distinguished from the criminal one by its negligence compared to the voluntary intent in the criminal case. The psychological state of the perpetrator of criminal conduct can be analyzed from a biopsychosocial perspective as much as the civil one. In this regard, in the civil case, such as in forensic disability and related assessments, pre-existing, precipitating, and perpetuating factors need to be considered causally, with personal and social resilience and protective factors added, as well. In the criminal context, the same biopsychosocial model applies, but with mental competence and voluntariness added as a critical factor. The advent of neurolaw has led to use of neuroscience in court, but it risks reducing the complexity of criminal cases to unifactorial, biological models. PMID:26325348

  14. Assessment of the standard forensic procedure for the evaluation of psychological injury in intimate-partner violence.

    PubMed

    Fariña, Francisca; Arce, Ramón; Vilariño, Manuel; Novo, Mercedes

    2014-01-01

    In judicial terms, a victim refers to any person who has suffered injury arising from an action or omission of an action that constitutes an offence, and the burden of proof lies with the prosecution. A review of Spanish judicial judgements underscored that the lack of evidence of psychological injury in cases of intimate-partner violence (IPV) accounted for approximately 40% of acquittals. Thus, the Spanish standard of proof for the forensic evaluation of psychological injury i.e., the MMPI-2 and the unstructured interview were assessed in order to determine if they met the statutory requirement for the assessment of psychological injury and the differential diagnosis of feigning. The results of the comparison of 51 women victims of IPV with firm convictions against their aggressors, and 54 women mock victims of IPV showed that the F, K, Fb, Fp and Ds scales, and the F-K index discriminated significantly and with medium and large effect sizes, between adjudicated and mock victims. However, the results did not provide a valid decision criterion for forensic settings i.e., false negatives (identifying feigner as honest protocols) were not classified correctly. In conclusion, the standard forensic procedure for the evaluation of psychological injury in cases of IPV did not constitute valid proof for judges who acquitted defendants on the grounds of not proven due to the lack of evidence of psychological injury.

  15. The Psychological Evaluation of Patients with Chronic Pain: a Review of BHI 2 Clinical and Forensic Interpretive Considerations.

    PubMed

    Bruns, Daniel; Disorbio, John Mark

    2014-01-01

    Pain is the most common reason why patients see a physician. Within the USA, it has been estimated that at least 116 million US adults suffer from chronic pain, with an estimated annual national economic cost of $560-635 billion. While pain is in part a sensory process, like sight, touch, or smell, pain is also in part an emotional experience, like depression, anxiety, or anger. Thus, chronic pain is arguably the quintessential biopsychosocial condition. Due to the overwhelming evidence of the biopsychosocial nature of pain and the value of psychological assessments, the majority of chronic pain guidelines recommend a psychological evaluation as an integral part of the diagnostic workup. One biopsychosocial inventory designed for the assessment of patients with chronic pain is the Battery for Health Improvement 2 (BHI 2). The BHI 2 is a standardized psychometric measure, with three validity measures, 16 clinical scales, and a multidimensional assessment of pain. This article will review how the BHI 2 was developed, BHI 2 concepts, validation research, and an overview of the description and interpretation of its scales. Like all measures, the BHI 2 has strengths and weaknesses of which the forensic psychologist should be aware, and particular purposes for which it is best suited. Guided by that knowledge, the BHI 2 can play a useful role in the forensic psychologist's toolbox. PMID:25478059

  17. Failings of trauma-specific and related psychological tests in detecting post-traumatic stress disorder in forensic settings.

    PubMed

    Kleinman, Stuart B; Martell, Daniel

    2015-01-01

    Judges and juries tend to be particularly impressed by test data, especially quantitative test data. Psychometric tests specific for assessing the presence of post-traumatic stress disorder (PTSD) are commonly employed by forensic mental health evaluators. Most of these instruments, however, have been designed to detect PTSD in treatment or research, and not forensic, settings. Those who rely on these measures without adequate awareness of their often significant limits in correctly identifying malingering may induce finders of fact to inordinately confidently accept the presence of PTSD. This article reviews problematic structural and content components of trauma-specific and related instruments used to evaluate PTSD and discusses the utility of specific techniques liable to be used in forensic settings to "fool" these measures.

    Forensic chemistry is unique among chemical sciences in that its research, practice, and presentation must meet the needs of both the scientific and the legal communities. As such, forensic chemistry research is applied and derivative by nature and design, and it emphasizes metrology (the science of measurement) and validation. Forensic chemistry has moved away from its analytical roots and is incorporating a broader spectrum of chemical sciences. Existing forensic practices are being revisited as the purview of forensic chemistry extends outward from drug analysis and toxicology into such diverse areas as combustion chemistry, materials science, and pattern evidence.

    We now have a confusing set of five commonly used terms for the application of Earth evidence in forensic science. This confusion is resulting in Earth scientists who use these methods mentioning different terms, sometimes for the same type of study. Likewise, forensic scientists, police/law enforcement officers and those employed by courts of law are becoming confused as to what each term means. A nomenclatural framework (based on the first use of each term) is proposed to encourage consistency in the use of terminology. Generally, the number of Earth science applications has grown through time, from soil and sediment analysis to remote sensing and GIS. The issue of where forensic biology and microbiology sits with these uses of Earth evidence is considered. PMID:20430544

    2010-01-01

    Odour of the animal or human corpses immediately after death is very attractive for insects and other invertebrates. Blue and green bottle flies from the Calliphoridae family are the first colonizers of cadaver and immediately later necrophagous Diptera from the Sarcophagidae family settle on the same corpse. It is essential to determine the time past after death for elucidating the event in case of the homicide or suspicious death, and it is directly proportional to the post mortem interval expected time, which is based upon the speed of the larval growth. In this article, we purposed to stress the special interest of forensic entomology for the scientists who will apply this science in their forensic researches and case studies, and also to provide information to our judges, prosecutors and law enforcement agents in order to consider the entomological samples to be reliable and applicable evidences as biological stains and hairs. We are of the opinion that if any forensic entomologist is called to the crime scene or if the evidences are collected and then delivered to an entomologist, the forensic cases will be elucidated faster and more accurately.

    Forensic hospital records of 39 severely mentally ill mothers adjudicated Not Guilty by Reason of Insanity for filicide (child murder by parents) were analyzed to describe characteristics preceding this tragedy and to suggest prevention strategies. Almost three-quarters of the mothers (72%) had previous mental health treatment. Over two thirds (69%) of the mothers were experiencing auditory hallucinations, most frequently command hallucinations, and half (49%) were depressed at the time of the offense. Over one third (38%) of the filicides occurred during pregnancy or the postpartum period, and many had a history of postpartum psychosis. Almost three-quarters (72%) of the mothers had experienced considerable developmental stressors, such as death of their own mother or incest. Maternal motives for filicide were predominantly "altruistic" (meaning murder out of love) or "acutely psychotic" (occurring in the throes of psychosis, without rational motive). Psychiatrists should perform careful risk assessments for filicide in mothers with mental illnesses. PMID:16382847

    The importance and relevance of forensic practice to societal evolution has increased exponentially in recent years. As society evolves in its understanding of the complex relationships between mankind and society, we rely more and more on the services of forensic experts. This article elucidates the professions of forensic psychiatry and forensic psychology. We examine the two distinct professions from the spectrum of collaboration, integration of services, differences, and similarities. We also compare and contrast the educational background and training requirements for these two professions; and present illustrative scenarios and real life examples of the daily functions of both professionals. Lastly, we present demographic data for the areas of employment, numbers, and geographic distribution of the two professions. Forensic psychiatry is the interface between medicine and law, while forensic psychology is the interface between psychology and law. As such, these professions are mired with complexities and challenged by vulnerabilities. Professionals from both fields can serve as expert witnesses in court and therefore face similar challenges in their course of professional practice. Collaboration between these two professions has the potential to increase both the credibility and utility of forensic services to the courts, the individuals served, and the general public.

    Russo, Andrea; Urlić, Ivan; Kasum, Josip

    2015-09-01

    Forensics (forensic--before the Forum) means the application of knowledge from different scientific fields in order to define facts in judicial and/or administrative procedures. Nowadays forensics, besides this, finds its application even in different economic processes. For example, forensics enters the commercial areas of business intelligence and of different security areas. The European Commission recognized the importance of forensics, and underscored the importance of development of its scientific infrastructure in member States. We are witnessing the rise of various tragedies in economic and other kinds of processes. Undoubtedly, the world is increasingly exposed to various forms of threats whose occurrences regularly involve people. In this paper we are proposing the development of a new approach in the forensic assessment of the state of human resources. We are suggesting that in the focus should be the forensic approach in the psychological assessment of awareness of the individual and of the critical infrastructure sector operator (CISO) in determining the level of actual practical, rather than formal knowledge of an individual in a particular field of expertise, or in a specific scientific field, and possible forensic meanings.

    2014-02-01

    Geomorphology plays a critical role in two areas of geoforensics: searching the land for surface or buried objects and sampling scenes of crime and control locations as evidence. Associated geoscience disciplines have substantial bodies of work dedicated to their relevance in forensic investigations, yet geomorphology (specifically landforms, their mapping and evolution, soils and relationship to geology and biogeography) have not had similar public exposure. This is strange considering how fundamental to legal enquiries the location of a crime and its evolution are, as this article will demonstrate. This work aims to redress the balance by showing how geomorphology featured in one of the earliest works on forensic science methods, and has continued to play a role in the sociology, archaeology, criminalistics and geoforensics of crime. Traditional landscape interpretation from aerial photography is used to demonstrate how a geomorphological approach saved police time in the search for a clandestine grave. The application geomorphology has in military/humanitarian geography and environmental/engineering forensics is briefly discussed as these are also regularly reviewed in courts of law.

  12. Multimedia Forensics Is Not Computer Forensics

    NASA Astrophysics Data System (ADS)

    Böhme, Rainer; Freiling, Felix C.; Gloe, Thomas; Kirchner, Matthias

    The recent popularity of research on topics of multimedia forensics justifies reflections on the definition of the field. This paper devises an ontology that structures forensic disciplines by their primary domain of evidence. In this sense, both multimedia forensics and computer forensics belong to the class of digital forensics, but they differ notably in the underlying observer model that defines the forensic investigator’s view on (parts of) reality, which itself is not fully cognizable. Important consequences on the reliability of probative facts emerge with regard to available counter-forensic techniques: while perfect concealment of traces is possible for computer forensics, this level of certainty cannot be expected for manipulations of sensor data. We cite concrete examples and refer to established techniques to support our arguments.

It is necessary to come to grips with the criminalistic and social pathological meaning of three terms--individual crime, grouped and organized crime as well as participation of forensic sciences including forensic medicine on solving problems of organized crime. Forensic medicine and forensic psychology can help to solve this acute problem of present development of social life. It can help in criminalistic expertize and insider activity in profiliation of perpetrators and victims. Mainly it will be about searching and improving of methodical approaches in solving of incriminated cases and its analysis for investigative organs and courts.

    NASA Astrophysics Data System (ADS)

    Amendt, Jens; Krettek, Roman; Zehner, Richard

    Necrophagous insects are important in the decomposition of cadavers. The close association between insects and corpses and the use of insects in medicocriminal investigations is the subject of forensic entomology. The present paper reviews the historical background of this discipline, important postmortem processes, and discusses the scientific basis underlying attempts to determine the time interval since death. Using medical techniques, such as the measurement of body temperature or analysing livor and rigor mortis, time since death can only be accurately measured for the first two or three days after death. In contrast, by calculating the age of immature insect stages feeding on a corpse and analysing the necrophagous species present, postmortem intervals from the first day to several weeks can be estimated. These entomological methods may be hampered by difficulties associated with species identification, but modern DNA techniques are contributing to the rapid and authoritative identification of necrophagous insects. Other uses of entomological data include the toxicological examination of necrophagous larvae from a corpse to identify and estimate drugs and toxicants ingested by the person when alive and the proof of possible postmortem manipulations. Forensic entomology may even help in investigations dealing with people who are alive but in need of care, by revealing information about cases of neglect.

  17. Sexual assault, irresistible impulses, and forensic psychiatry in Sweden.

    PubMed

    Bergenheim, Asa

    2014-01-01

    After forensic psychiatry was firmly established in Sweden in the 1930s, many rapists and individuals charged with assaulting children underwent a forensic psychiatric examination. The physicians found that most of them had not been "in control" of their senses or not "in complete control" of their senses at the time of the crime. If the court ordered a forensic psychiatric examination, the defendant had a very good chance of either being discharged or having his sentence reduced considerably. By the 1950s psychological perspectives began to dominate in forensic psychiatry. In the forensic records of the 1950s we can notice a shift from a biomedical to a socio-psychological perspective, and crime was increasingly related to conditions that were not seen as mental derangement from a legal point of view. As a result, it became less and less common, from the 1950s onwards, for sentences to be commuted or defendants discharged. PMID:24315847

    Drummer, Olaf H

    2010-01-01

    Forensic toxicology has developed as a forensic science in recent years and is now widely used to assist in death investigations, in civil and criminal matters involving drug use, in drugs of abuse testing in correctional settings and custodial medicine, in road and workplace safety, in matters involving environmental pollution, as well as in sports doping. Drugs most commonly targeted include amphetamines, benzodiazepines, cannabis, cocaine and the opiates, but can be any other illicit substance or almost any over-the-counter or prescribed drug, as well as poisons available to the community. The discipline requires high level skills in analytical techniques with a solid knowledge of pharmacology and pharmacokinetics. Modern techniques rely heavily on immunoassay screening analyses and mass spectrometry (MS) for confirmatory analyses using either high-performance liquid chromatography or gas chromatography as the separation technique. Tandem MS has become more and more popular compared to single-stage MS. It is essential that analytical systems are fully validated and fit for the purpose and the assay batches are monitored with quality controls. External proficiency programs monitor both the assay and the personnel performing the work. For a laboratory to perform optimally, it is vital that the circumstances and context of the case are known and the laboratory understands the limitations of the analytical systems used, including drug stability. Drugs and poisons can change concentration postmortem due to poor or unequal quality of blood and other specimens, anaerobic metabolism and redistribution. The latter provides the largest handicap in the interpretation of postmortem results. PMID:20358697

    2013-01-01

    There is a growing awareness among mental health practitioners that many mental disorders previously believed to be primarily behavioral in nature, reflecting character and environment, are actually grounded in brain mal-development or brain disorder. This growing awareness, influenced by the advent of new diagnostic procedures and measures, is also found among forensic practitioners. In this paper, we describe some of the elements involved in conducting a neurobehavioral assessment of cognitive functioning, particularly in capital cases, organizing this material in terms of the professional disciplines – social work, mitigation investigation, psychological, and medical – with which these methods are mainly identified. The paper concludes with a brief discussion of how to integrate the multiple areas of expertise to create an accurate understanding of the neurobehavioral functioning and capacity of the subject. This is the basis from which civil and criminal forensic opinions must emanate. PMID:23059206

    Sexual violence is a significant cause of physical and psychological harm and suffering for women and children. Although sexual violence mostly affects women and girls, boys are also subject to child sexual abuse. Nurse is the person who attends the victim first. In order to meet the rigid and ever-changing demands of providing care to the victim and complying with our confusing system of laws, the nursing should has been forced to expand into a Forensic nursing, specialty of its own. Nursing roles in the criminal justice service known by many names worldwide-Custody nursing, Prison/Correctional nursing, Immigration centre nursing, Sexual Assault Nurse Examiner (SANE) or Sexual Assault Forensic Examiner (SAFE), SARTs (Sexual assault response team), SARCs (Sexual assault referral centre) and FNDIs (Forensic nurse death investigator). In India the premier institutes like AIIMS New Delhi and The PGI Chandigarh, do not have forensic content in their nursing curriculum manuals. The WHO and IAFN have urged inclusion of forensic content in both undergraduate and postgraduate nursing programs. Forensic Nurse Specialist can provide direct services to individual clients, consultation services to nursing, medical and law-related agencies, as well as providing expert court testimony in areas dealing with trauma and/or questioned death investigative processes, adequacy of services delivered, and specialized diagnoses of specific medical conditions. Research Findings on the Effectiveness of Sexual Assault Nurse Examiner (SANE) Programs suggests various improvements in each and every step in care of victim of sexual assault. PMID:27314972

  2. Forensic Neuropsychology: are we there yet?

    Forensic Neuropsychology is a new and rapidly evolving subspecialty of clinical neuropsychology that applies neuropsychological principles and practices to matters that pertain to legal decision-making. Forensic neuropsychologists provide the trier of fact with specialized information regarding brain-behavior relationships. The primary responsibility of the forensic neuropsychologist is to provide information based on scientifically-validated neuropsychological principles and clinical methodology that is pertinent to the Forensic Question at hand-which is not just whether the patient has dysfunction, but whether the dysfunction results from the event under consideration. To best answer the Forensic Question, the neuropsychologist must use a methodology that has been scientifically-validated on brain-impaired individuals, and can distinguish various brain conditions from each other as well as from normal variation. The methodology must be able to determine whether any dysfunction found is, in fact, the result of a neurological condition as opposed to non-neurological, psychological, or even factitious disorders. This paper discusses neuropsychological methodology in the context of forensic application and the requirements of the legal process and illustrates these issues with case examples. PMID:14609579

    Pathogens and toxins can be converted to bioweapons and used to commit bioterrorism and biocrime. Because of the potential and relative ease of an attack using a bioweapon, forensic science needs to be prepared to assist in the investigation to bring perpetrators to justice and to deter future attacks. A new subfield of forensics--microbial forensics--has been created, which is focused on characterization of evidence from a bioterrorism act, biocrime, hoax, or an inadvertent release. Forensic microbiological investigations are essentially the same as any other forensic investigation regarding processing. They involve crime scene(s) investigation, chain of custody practices, evidence collection, handling and preservation, evidence shipping, analysis of evidence, interpretation of results, and court presentation. In addition to collecting and analyzing traditional forensic evidence, the forensic investigation will attempt to determine the etiology and identity of the causal agent, often in a similar fashion as in an epidemiologic investigation. However, for attribution, higher-resolution characterization is needed. The tools for attribution include genetic- and nongenetic-based assays and informatics to attempt to determine the unique source of a sample or at least eliminate some sources. In addition, chemical and physical assays may help determine the process used to prepare, store, or disseminate the bioweapon. An effective microbial forensics program will require development and/or validation of all aspects of the forensic investigative process, from sample collection to interpretation of results. Quality assurance (QA) and QC practices, comparable to those used by the forensic DNA science community, are being implemented. Lastly, partnerships with other laboratories will be requisite, because many of the necessary capabilities for analysis will not reside in the traditional forensic laboratory. PMID:15821943

    The number of civil lawsuits related to sexual harassment is increasing. The author bases this paper on her experience as an expert witness in 28 sexual harassment cases over the last 10 years. She delineates the psychological and legal issues about which forensic psychiatrists may be consulted. These include issues related to helping a jury determine the veracity of the complaints of harassment, the psychological effects of the harassment, the prognosis, and the treatment for women who have been harassed. The author gives examples of cases where psychiatric testimony was given to help in the decision making about damages related to the psychological effects of sexual harassment. PMID:1482795

    The University of Porto (UP) provides education in Forensic Medicine (FM) through the 1st, 2nd and 3rd cycle of studies, post-graduation and continuing education courses. This education is related to forensic pathology, clinical forensic medicine (including forensic psychology and psychiatry), forensic chemistry and toxicology, forensic genetics and biology, and criminalistics. With this work we intent to reflect on how we are currently teaching FM in the UP, at all levels of university graduation. We will present our models, regarding the educational objectives, curricular program and teaching/learning methodologies of each cycle of studies as well as in post-graduate and continuing education courses. Historically, and besides related administratively to the Ministry of Justice, the Portuguese Medico-Legal Institutes (since 1918) and more recently the National Institute of Legal Medicine and Forensic Sciences (INMLCF) also have educational and research responsibilities. Thus, it lends space and cooperates with academic institutions and this contribution, namely regarding teaching forensic sciences in Portugal has been judged as an example for other Countries. This contribution is so important that in UP, the Department of Legal Medicine and Forensic Sciences of the Faculty of Medicine (FMUP) shares, until now, the same physical space with North Branch of the INMLCF, which represents a notorious advantage, since it makes possible the "learning by doing".

    During the last decade, neuropsychology has emerged as one of the fastest growing disciplines within clinical psychology. One of the most important roles for neuropsychologists is their contribution to the forensic sciences. The present paper reviews how lawyers may best utilize the services of clinical neuropsychologists. Suggestions are also offered to neuropsychologists on how better to meet the needs of lawyers. The following forensic science issues are discussed: the legal framework in which neuropsychologists function; contributions psychologists may make towards answering basic medicolegal questions such as the elucidation of the nature, extent, and duration of head injury sequelae; criteria for acceptable neuropsychological reports; medicolegal aspects of severe head injury, minor head injury (posttraumatic syndrome), and pseudo-head injury (malingering). There are many causes of damage to the nervous system (for example, industrial toxins and medical malpractice) that are eligible for compensation. Examples will be confined to head injury since the basic forensic science principles remain the same, whatever the etiology of such brain damage. PMID:6619781

    2009-10-01

    This report documents the architecture and implementation of a Parallel Digital Forensics infrastructure. This infrastructure is necessary for supporting the design, implementation, and testing of new classes of parallel digital forensics tools. Digital Forensics has become extremely difficult with data sets of one terabyte and larger. The only way to overcome the processing time of these large sets is to identify and develop new parallel algorithms for performing the analysis. To support algorithm research, a flexible base infrastructure is required. A candidate architecture for this base infrastructure was designed, instantiated, and tested by this project, in collaboration with New Mexico Tech. Previous infrastructures were not designed and built specifically for the development and testing of parallel algorithms. With the size of forensics data sets only expected to increase significantly, this type of infrastructure support is necessary for continued research in parallel digital forensics. This report documents the implementation of the parallel digital forensics (PDF) infrastructure architecture and implementation.

    This article reviews existing forensic psychiatric services in Pakistan highlighting the role played by the judicial and the medical fraternity in managing the legal and forensic issues of the population of patients with mental illnesses. Until 2001, all legal and forensic issues were dealt with the mental health legislation of 1912, the Lunacy Act of 1912. This was inherited from the British rulers in the Sub-Continent at the time. The Mental Health Ordinance of 2001 could not sustain following the 18th constitutional amendment in 2010, whereby psychiatric healthcare was devolved to the provinces from the previous federal authority. The article also highlights the difficulties and the barriers in implementation of the forensic psychiatric services in Pakistan at various levels within the healthcare system. This article also delves into the current framework of training in forensic psychiatry for postgraduates as well as the assessments and management schedules for the mentally ill offenders at tertiary care institutions in Pakistan.

    2015-01-01

    The construction of a written forensic report is a core component of forensic practice, demonstrating the evaluator's skill in conducting the evaluation and in communicating relevant information to the legal audience in an effective manner. Although communication skills and quality of written documentation are important in clinical psychiatry generally, they form the sine qua non of successful forensic work, which consists in telling complex stories in a coherent and compelling fashion. High quality forensic reports require careful preparation from the earliest stages of work on a case. They generally follow an expected structure, which permits the evaluator to provide all the data necessary to form a carefully reasoned opinion that addresses the legal questions posed. Formats and content of reports vary according to the type of case and the circumstances of the evaluation and so require flexibility within customary frameworks. The style and quality of writing are critical to the crafting of forensic reports. The effects on legal decision-makers of various approaches to the presentation of information in reports has not been studied empirically, but guidance from experienced forensic psychiatrists is available. There is a small body of research on quality improvement in forensic writing, and further empiric study is warranted. PMID:25603453

    Developments in forensic mass spectrometry tend to follow, rather than lead, the developments in other disciplines. Examples of techniques having forensic potential born independently of forensic applications include ambient ionization, imaging mass spectrometry, isotope ratio mass spectrometry, portable mass spectrometers, and hyphenated chromatography-mass spectrometry instruments, to name a few. Forensic science has the potential to benefit enormously from developments that are funded by other means, if only the infrastructure and personnel existed to adopt, validate, and implement the new technologies into casework. Perhaps one unique area in which forensic science is at the cutting edge is in the area of chemometrics and the determination of likelihood ratios for the evaluation of the weight of evidence. Such statistical techniques have been developed most extensively for ignitable-liquid residue analyses and isotope ratio analysis. This review attempts to capture the trends, motivating forces, and likely impact of developing areas of forensic mass spectrometry, with the caveat that none of this research is likely to have any real impact in the forensic community unless: (a) The instruments developed are turned into robust black boxes with red and green lights for positives and negatives, respectively, or (b) there are PhD graduates in the workforce who can help adopt these sophisticated techniques.

    Microbial forensics has been defined as the discipline of applying scientific methods to the analysis of evidence related to bioterrorism, biocrimes, hoaxes, or the accidental release of a biological agent or toxin for attribution purposes. Over the past 15 years, technology, particularly massively parallel sequencing, and bioinformatics advances now allow the characterization of microorganisms for a variety of human forensic applications, such as human identification, body fluid characterization, postmortem interval estimation, and biocrimes involving tracking of infectious agents. Thus, microbial forensics should be more broadly described as the discipline of applying scientific methods to the analysis of microbial evidence in criminal and civil cases for investigative purposes.

    Forensic dental identification specialists are typically the last conventional option for postmortem identification. Forensic dental identification is most often accomplished by comparing radiographs of the decedent's teeth with the dental radiographs obtained from the dentist of the suspected victim. Unfortunately, antemortem dental radiographs are not always available. When presented with this challenge, the authors of this article have been successful in completing identifications using means other than dental radiographic comparison. PMID:26126345

    Dike, Charles C; Nicholson, Elizabeth; Young, John L

    2015-12-01

    Patients in a forensic psychiatric facility often require escorted transport to medical facilities for investigations or treatments of physical health ailments. Transporting these patients presents significant safety and custody challenges because of the nature of patients housed in forensic psychiatric facilities. A significant proportion of these patients may be transfers from the Department of Corrections (DOC) under legal mandates for psychiatric evaluation and treatment better provided in a hospital setting, and most of them will return to the DOC. Although departments of correction have protocols for escorting these potentially dangerous individuals, it is unclear whether receiving psychiatric hospitals have established procedures for maintaining the safety of others and custody of these individuals during transportation outside the hospital facility. The literature is sparse on precautions to be observed when transporting dangerous forensic psychiatric patients, including those with high escape risk. In this article, we describe one forensic inpatient facility's procedure for determining the appropriate level needed to transport these individuals outside of the forensic facility. We also describe the risk assessment procedure for determining level of transport. These are quality improvement measures resulting from a critical review of an incident of escape from the forensic facility several years ago. PMID:26668224

The Internet is a learning tool, a research tool, a virtual library without borders and membership requirements, a journal with instant publication, a help desk, and a newspaper/journal with current information. Very soon, when live audio and video transmission is perfected, the Internet also will be a live classroom and everyday conference. Forensic scientists, laboratories and colleges should make use of information already available on the Internet. They also should actively participate and contribute. Very few forensic scientists and laboratories have made their presence felt by setting up their home pages/web pages. But, there is tremendous growth during the past year. Immense benefits from Internet to forensic community are discussed along with the author's personal experience. Creating on-line searchable data bases in all specialties of forensic science is an urgent need. Leading forensic journals should take a lead and create on-line searchable indexes with abstracts. On line electronic publishing, collaborative research/paper publishing or editing is easy, fast, economical and convenient through the use of the Internet. Creation of Internet repositories of unpublished papers is an idea worth looking into. Internet also can be used to give training, re-training or advanced training to students/forensic scientists.

  3. Forensic geology exhumed

    NASA Astrophysics Data System (ADS)

    Martinez, Joseph Didier

    Forensic geology binds applied geology to the world of legal controversy and action. However, the term “forensic” is often misconstrued. Although even some attorneys apply it only to the marshalling of evidence in criminal cases, it has a much broader definition. One dictionary defines it as “pertaining to, connected with, or used in courts of law or public discussion and debate.” The American Geological Institute's Glossary of Geology defines forensic geology as “the application of the Earth sciences to the law.” The cited reference to Murray and Tedrow [1975], however, deals mostly if not exclusively with the gathering and use of evidence in criminal cases, despite the widespread involvement of geologists in more general legal matters. It seems appropriate to “exhume” geology's wider application to the law, which is encompassed by forensic geology.

    Background: Forensic odontology nowadays has become a developing science and is of great importance to society. It is important that dental practitioners should have a proper knowledge of forensics as the need has increased greatly over the last decades due to the unprecedented demand from the criminal justice including terrorism in Kashmir valley (J&K India). Materials and Methods: Data was collected based on questionnaire survey among qualified dental practitioners related to their awareness of forensic odontology. Results: A total number of 235 dental practitioners responded to the questionnaire. Results showed that there was a low confidence, in handling of forensic odontology related cases among dental practitioners and majority of dental practitioners were not having any formal training in forensic odontology. Conclusion: Each dental practitioner has a responsibility to understand the forensic implications associated with the practice of his profession and thus he should work sincerely enough so to ensure his contribution in the field of forensic odontology.

    PubMed

    Winter, Alison

    2013-03-01

    This paper examines the fortunes of the controversial use of hypnosis to 'enhance' autobiographical memories in postwar America. From the 1950s through the early 1980s, hypnosis became increasingly popular as a means to exhume information thought to be buried within the mind. This practice was encouraged by lay understandings of memory drawn from a material culture full of new recording devices (motion pictures, tape and then video recorders); and during the years when the practice was becoming most popular and accepted, academic psychologists developed a contrary, reconstructive, account of memory that was put to use in a series of battles meant to put an end to hypnotic recall. But popular commitment to the idea of permanent memory 'recordings' sustained the practice and the assumptions about memory and self that were associated with it, and in the face of a culture of academic psychology fully committed to the idea of 'reconstructive', malleable memory, a tidal wave of 'enhanced' memories swept America in the late 1980s and 1990s, in the so-called 'memory wars'. These, in turn, provoked academic psychologists to research the claims and counter claims central to the memory wars. The paper will also make an argument about the importance of lay knowledge in the psychological sciences explored in this paper: that popular psychological beliefs played a significant, even formative role in defining the nature of forensic psychological expertise, and also the framing of elite academic psychological research.

    In this paper, we discuss the current medico-legal practice and future plan to improve the medico-legal service of Bangladesh which is rooted in the remnants of British medical jurisprudence. It includes clinical forensic medicine and forensic pathology. In Bangladesh all unnatural deaths are to be reported at the nearest police station and an appointed police officer should visit the scene of crime for investigation and to arrange postmortem if required. The forensic services of the country are delivered partly by academic staffs of Government Medical Colleges and the rest by the Civil Surgeons. Sometimes, residential medical officers in the district hospitals perform the medico-legal work. Most of them have no forensic qualifications except a long exposure in the medico-legal field. Currently academic and professional postgraduate courses are available. The chemical examiner's laboratory is situated at Dhaka with the facility of quantitative tests only. The Government of Bangladesh is trying to standardize the existing system. A Workshop on medico-legal services has been organized regularly by The Medico-legal Society of Bangladesh. A DNA profiling laboratory at the Dhaka Medical College is in the process of being set up. Such progress will be a milestone in the development of the medico-legal service in Bangladesh. However, with a few exceptions, teaching and training facilities are still lacking. PMID:12935633

    Children living in foster care are a unique population with specialized healthcare needs. This article will assist forensic nurses and advanced practice forensic nurses, particularly those working in pediatrics, in understanding the needs of children in foster care and implementing a practice plan to better meet their healthcare needs. To that end, a basic understanding of the foster care system is crucial and involves an appreciation of the interface between the legal system and the child welfare system. Most important to providing care to children in foster care is a true understanding of trauma exposure and its potential effects on the lives of children: physically, developmentally, emotionally, and psychologically. This article will assist forensic nurses working with pediatric populations to more fully understand the needs of children in foster care and to develop innovative interventions to appropriately meet their unique needs.

    PubMed

    Simopoulos, Eugene F; Cohen, Bruce

    2015-12-01

    Effective practice of forensic psychiatry is dependent on a clinical recognition and understanding of core psychodynamic principles and theory. Practice guidelines, rooted in the ethics-based imperative to strive for honesty and objectivity, demand that practitioners remain vigilant to the development of bias and appreciate interpersonal dynamics that may be re-enacted in the forensic setting. Although it is not feasible to maintain complete impartiality, especially when confronted with the nature of certain offenses, knowledge of both conscious and unconscious responses can bolster the intellectual integrity of the clinical assessment. The identification of defense mechanisms within both the evaluator and evaluee and attention to transference and countertransference are essential for an accurate conceptualization of an offender's psychological functioning, vulnerabilities, and risk of reoffense. In this article, we review psychodynamic concepts and their potential impact in the forensic setting and underscore interventions that may aid in the elucidation and management of these processes.

    Veterinary pathologists working in diagnostic laboratories are sometimes presented with cases involving animal poisonings that become the object of criminal or civil litigation. Forensic veterinary toxicology cases can include cases involving animal cruelty (malicious poisoning), regulatory issues (eg, contamination of the food supply), insurance litigation, or poisoning of wildlife. An understanding of the appropriate approach to these types of cases, including proper sample collection, handling, and transport, is essential so that chain of custody rules are followed and proper samples are obtained for toxicological analysis. Consultation with veterinary toxicologists at the diagnostic laboratory that will be processing the samples before, during, and after the forensic necropsy can help to ensure that the analytical tests performed are appropriate for the circumstances and findings surrounding the individual case.

Extracting data (file) out of undifferentiated blocks (raw data) is called as carving. Identifying and recovering files based on analysis of file formats is known as file carving. In Cyber Forensics, carving is a helpful technique in finding hidden or deleted files from digital media. A file can be hidden in areas like lost clusters, unallocated clusters and slack space of the disk or digital media. To use this method of extraction, a file should have a standard file signature called a file header (start of the file). A search is performed to locate the file header and continued until the file footer (end of the file) is reached. The data between these two points will be extracted and analyzed to validate the file. The extraction algorithm uses different methods of carving depending on the file formats.

    Parricide is the act of murdering one's father (patricide), mother (matricide) or other close relative, but usually not children (infanticide). It is a rare event and little information is available on this topic. This study aims to increase knowledge about this phenomenon, promoting the timely detection of problematic cases and avoiding fatalities. A retrospective study based on the autopsy reports of parricide victims performed by the North Services of the National Institute of Legal Medicine and Forensic Sciences of Portugal between 2003 and 2011, as well as on the judicial outcome of each case, was performed. Seven cases of parricide were found, corresponding to 1.7% of all the homicides undergoing forensic evaluated. Victims and perpetrators were typically males. The assaults occurred all at home, in the presence of witnesses, and the perpetrator remained at the scene after the crime. The main alleged reasons were untreated psychiatric illness and financial conflicts in the cases of adult parricide, and attempts to protect the mother from intimate partner violence in younger ones. The judicial outcomes ranged from acquittal for nonimputability to conviction for murder, manslaughter or involuntary manslaughter. This study was carried out on a forensic sample and it is useful to implement strategies to prevent parricide. PMID:24485411

    Finding dedicated sites on the World Wide Web (WWW) touching upon issues related to the autopsy which could be of use to forensic practitioners is, as with other areas of forensic medicine and science, a time-consuming task. Unfortunately, one has to wade through lists related to 'Alien autopsy' sites and even 'Furby autopsy' sites that are generated by the most commonly used web search engines, which have been featured in earlier web reviews. Numerous sites containing large archives of autopsy photographs are available on the web. However, many of these sites represent the darker side of the WWW as they are often presented purely for titillation. Unfortunately, one can equate these sites to the modern-day version of the Victorian 'freak show'--Typically, these sites ask for your Visa card number to view their contents, and several have links to pornography sites; one even links to a Satanist site. Luckily a few of these sites do now require age confirmation codes. As many of these sites show autopsy photographs from real cases one has to ask how these were obtained and who is placing them on the WWW. This review does not list any of these sites for obvious reasons, but it does draw the reader's attention to sites touching upon issues related to autopsies which forensic practitioners may wish to visit or use.

    Now that one has logged onto the world wide web (WWW) and utilized one or more of the home pages listed previously (or used another equally good home page) to seek out basic information available to forensic practitioners, the question now arises of how to go about making the most of the information available. One feature consistent to most home pages is links to the home pages of Associations and Societies, one or more of which most practitioners will be members of. With access to the WWW not only have you access to your own association/society, but you can also keep up to date with all the others to which you have not paid subscriptions. Although an internet search using a WWW search engine or the 'top 6' home pages may assist in identifying a large number of association and society sites, one of the most useful places to start is the home page of the Indian Academy of Forensic Medicine (IAFM). This, to date, lists a total of 139 such sites. To access all the home pages listed may take in excess of 6 h so the following review looks at the range of sites available and recommends some places the author considers many people may wish to know and visit. Again, this is inevitably a personal choice and it is recognized that those sites not listed may, in fact, be the preferred choice for other users of the forensic WWW. PMID:15335474

    A computer software, RättsBASE (RB), was developed for all forensic pathology units in Sweden and introduced in 1992. Simultaneously, a corresponding software, ToxBASE (TB), was developed for the Department of Forensic Toxicology, where all forensic toxicology in Sweden is managed. Both of the databases were created using dBASE IV, and the programming was carried out according to specifications from the staff at the forensic toxicology and forensic pathology units. since the development or RB and TB was coordinated, the systems can run together smoothly. The purpose of both systems was to automate the offices and to enable compilation of detailed statistics. Installation of Novell Netware and ISDN-connections (Integrated Service Digital Network) has enabled rapid communication between the units and easy compilation of nationwide statistics of forensic pathology and forensic toxicology. the systems offer a wide spectrum of reports and include a simple module for evaluation of the importance of the forensic efforts for th whole death investigation. The configuration of the softwares has also enabled processing of a large amount of related toxicological and autopsy data that in turn has yielded a base for compilation of toxicology interpretation lists. This article includes a summary of the features of the software and a discussion of its benefits and limitations. PMID:15637819

    In the aftermath of the 2001 anthrax letters, researchers have been exploring ways to predict the production environment of unknown source microorganisms. Different mass spectral techniques are being developed to characterize components of a microbe’s culture medium including water, carbon and nitrogen sources, metal ions added, and the presence of agar. Individually, each technique has the potential to identify one or two ingredients in a culture medium recipe. However, by integrating data from multiple mass spectral techniques, a more complete characterization is possible. We present a Bayesian statistical approach to integrated microbial forensics and illustrate its application on spores grown in different culture media.

    Stable isotopes are being used for forensic science studies, with applications to both natural and manufactured products. In this review we discuss how scientific evidence can be used in the legal context and where the scientific progress of hypothesis revisions can be in tension with the legal expectations of widely used methods for measurements. Although this review is written in the context of US law, many of the considerations of scientific reproducibility and acceptance of relevant scientific data span other legal systems that might apply different legal principles and therefore reach different conclusions. Stable isotopes are used in legal situations for comparing samples for authenticity or evidentiary considerations, in understanding trade patterns of illegal materials, and in understanding the origins of unknown decedents. Isotope evidence is particularly useful when considered in the broad framework of physiochemical processes and in recognizing regional to global patterns found in many materials, including foods and food products, drugs, and humans. Stable isotopes considered in the larger spatial context add an important dimension to forensic science.

    Nanoparticles appear in several areas of forensic science including security documents, paints, inks, and reagents that develop latent prints. One reagent (known as the silver physical developer) that visualizes the water insoluble components of latent print residue is based on the formation of highly charged silver nanoparticles. These attach to and grow on the residue and generate a silver image. Another such reagent involves highly charged gold nanoparticles. These attach to the residue forming a weak gold image which can be amplified with a silver physical developer. Nanoparaticles are also used in items such as paints, printing inks, and writing inks. Paints and most printing inks consist of nano-sized pigments in a vehicle. However, certain modern ink jet printing inks now contain nano-sized pigments to improve their light fastness and most gel inks are also based on nano scale pigments. These nanoparticlecontaining materials often appear as evidence and are thus subject to forensic characterization. Both luminescent (quantum dots), up-converting nano scale phosphors, and non luminescent nanoparticles are used as security tags to label product, add security to documents, and as anti counterfeiting measures. These assist in determining if an item is fraudulently made.

    In the past decade there has been a significant increase in the popularity of synthetic cathinones in the illegal drug market. They have been easily available from Internet-based vendors as well as at "head shops" and "smart shops". The recent prominence of synthetic cathinones can be attributed to their stimulatory properties similar to those of amphetamines. This paper provides a review on the current popular cathinone derivatives, their history and prevalence in the illegal drug market, legislation of these drugs in various countries, pharmacology, toxicology, and metabolism studies, analysis of toxicology samples (blood, urine, and hair) and criminalistic samples (seized, purchased via the Internet, and synthesized). From the reviewed literature, it is concluded that the products sold as "legal highs" do not only contain cathinone but also cathinone derivatives, and adulterants such as caffeine, lidocaine, and inorganic materials. Full toxicity data is currently unavailable for this drug class and hence more research is required with regard to their analysis and metabolism. Moreover, clandestine chemists are constantly synthesizing new derivatives and hence forensic chemists often need to synthesize and characterize these drugs to confirm the identity of the seized samples. This is expensive as well as time-consuming. Therefore, there is a need for national and international collaboration among forensic chemists to overcome this difficulty. PMID:26226850

    Nuclear Forensics is a growing field that is concerned with all stages of the process of creating and detonating a nuclear weapon. The main goal is to prevent nuclear attack by locating and securing nuclear material before it can be used in an aggressive manner. This stage of the process is mostly paperwork; laws, regulations, treaties, and declarations made by individual countries or by the UN Security Council. There is some preliminary leg work done in the form of field testing detection equipment and tracking down orphan materials; however, none of these have yielded any spectacular or useful results. In the event of a nuclear attack, the first step is to analyze the post detonation debris to aid in the identification of the responsible party. This aspect of the nuclear forensics process, while reactive in nature, is more scientific. A rock sample taken from the detonation site can be dissolved into liquid form and analyzed to determine its chemical composition. The chemical analysis of spent nuclear material can provide valuable information if properly processed and analyzed. In order to accurately evaluate the results, scientists require information on the natural occurring elements in the detonation zone. From this information, scientists can determine what percentage of the element originated in the bomb itself rather than the environment. To this end, element concentrations in soils from sixty-nine different cities are given, along with activity concentrations for uranium, thorium, potassium, and radium in various building materials. These data are used in the analysis program Python.

    Before the routine use of DNA profiling, blood typing was an important forensic tool. However, blood typing was not very discriminating. For example, roughly 30% of the United States population has type A-positive blood. Therefore, if A-positive blood were found at a crime scene, it could have come from 30% of the population. DNA profiling has a much better ability for discrimination. Forensic laboratories no longer routinely determine blood type. If blood is found at a crime scene, DNA profiling is performed. From Jeffrey's discovery of DNA fingerprinting to the development of PCR of STRs to the formation of DNA databases, our knowledge of DNA and DNA profiling have expanded greatly. Also, the applications for which we use DNA profiling have increased. DNA profiling is not just used for criminal case work, but it has expanded to encompass paternity testing, disaster victim identification, monitoring bone marrow transplants, detecting fetal cells in a mother's blood, tracing human history, and a multitude of other areas. The future of DNA profiling looks expansive with the development of newer instrumentation and techniques. PMID:22693781

    Since the publication of the first 'Forensic Web Watch' article a new search engine has become available, free of charge at the time of writing, to surfers of the Internet (Net). Fast Search claims to seek out sites of interest for the user from 'all the Web, all the time trade mark ' as opposed to parts of the Net as is more common with other search machines. It is easy to use, extremely fast but as it searches so much more of the Net, the end result is considerably larger. This, in turn, may lead to a longer time to seek out useful information as opposed to the obscure. Having said this, it is recommended to add to your search engine bookmarks. A search for sites on issues related to 'Police Surgeons' will yield limited information, as each country will have a different person filling this role, all referred to by different terms. The one common feature, however, to all such groups as well as forensic pathologists and scientists, is that they will work with, or in some cases for, the police services of their respective country. Thus, in this article we will look at sites related to the police which may have useful information related to their work, specific cases of interest and research and development which may effect our practice.

    Nuclear terrorism has been identified as one of the most serious security threats facing the world today. Many countries, including the United States, have incorporated nuclear forensic analysis as a component of their strategy to prevent nuclear terrorism. Nuclear forensics involves the laboratory analysis of seized illicit nuclear materials or debris from a nuclear detonation to identify the origins of the material or weapon. Over the years, a number of forensic signatures have been developed to improve the confidence with which forensic analysts can draw conclusions. These signatures are validated and new signatures are discovered through research and development programs and in round-robin exercises among nuclear forensic laboratories. The recent Nuclear Smuggling International Technical Working Group Third Round Robin Exercise and an on-going program focused on attribution of uranium ore concentrate provide prime examples of the current state of nuclear forensics. These case studies will be examined and the opportunities for accelerator mass spectrometry to play a role in nuclear forensics will be discussed.

    In the rules of evidence in all legal jurisdictions, medical experts are required to maintain objectivity when providing opinions. When interpreting medical evidence, doctors must recognise, acknowledge and manage uncertainties to ensure their evidence is reliable to legal decision-makers. Even in the forensic sciences such as DNA analysis, implicit bias has been shown to influence how results are interpreted from cognitive and contextual biases unconsciously operating. In cases involving allegations of child abuse there has been significant exposure in the media, popular magazines, legal journals and in the published medical literature debating the reliability of medical evidence given in these proceedings. In these cases judges have historically been critical of experts they perceived had sacrificed objectivity for advocacy by having an investment in a 'side'. This paper firstly discusses the issue of bias then describes types of cognitive biases identified from psychological research applied to forensic evidence including adversarial bias, context bias, confirmation bias and explains how terminology can influence the communication of opinion. It follows with previously published guidelines of how to reduce the risk of bias compromising objectivity in forensic practices then concludes with my own recommendations of practices that can be used by child protection paediatricians and within an organisation when conducting forensic evaluations of suspicious childhood injury to improve objectivity in formulation of opinion evidence.

    The analysis of four different biodiesel blends, as well as homemade biodiesel prepared from vegetable oil, has been performed using gas chromatography-mass spectrometry. The identification of methyl esters within the biodiesel along with any background components is made possible by recognizing their mass spectral fragmentation patterns. These fuels were subjected to typical fire scene environments, specifically weathering and microbial degradation, to investigate how these environments affect the analysis. A matrix study was also performed on wood, carpet, and clothing in order to identify any interferences from these substrates. The data obtained herein will provide the forensic science community with the data needed to help recognize these increasingly common ignitable liquids. PMID:27060442

This article surveys the neuroethics and neurolegal literature on the use of forensic neuroimaging within the courtroom. Next, the related literature within medical anthropology and science and technology studies is reviewed to show how debates about forensic neuroimaging reflect cultural tensions about attitudes regarding the self, mental illness, and medical expertise. Finally, recommendations are offered on how forensic psychiatrists can add to this research, given their professional interface between law and medicine. At stake are the fundamental concerns that surround changing conceptions of the self, sickness, and expectations of medicine. PMID:19535562

    Poorly implemented mental health reform policies are often given as reasons for the growth in demands for forensic psychiatric services and the steady increase of mental patients in prison systems. However, in this paper, additional reasons are advanced to explain the growth of forensic psychiatry, such as an expansion in the types of "psychiatric defences" in courts of law; public concerns about violent behaviour attributed to the mentally ill; the community management of paraphilias, especially pedophilia; the development of risk assessment methodologies and the halo of super-specialization. The net result of these developments is that patients who receive a label of "forensic" enter into a mental health ghetto with little connectivity or integration with the general mental health system. The forensic label increases the stigma and decreases opportunities for reintegration and full social recovery. The paper provides guidelines to reverse these trends. PMID:16946932

    Psychiatrists function, in part, as historians who rely on patient narratives to help them understand presenting mental disorders and explain their causes. Forensic psychiatrists have been skeptical of using narratives, raising concerns about their lack of objectivity and potential for bias. They also have criticized narratives as being more performative than scientific. Recent authors, however, have pointed out that narratives may be helpful in forming forensic opinions and supporting oral testimony, while stressing that their use must be consistent with the ethics espoused by forensic psychiatry. This article reviews the role of narratives in understanding human events and the ubiquitous presence of narratives in the judicial process. It delves into the inescapability of using explicit or implicit narratives in the course of forensic practice, as well as how they may be meaningfully incorporated into evaluations and find expression alongside scientific principles.

    Digital multimedia such as images and videos are prevalent on today's internet and cause significant social impact, which can be evidenced by the proliferation of social networking sites with user generated contents. Due to the ease of generating and modifying images and videos, it is critical to establish trustworthiness for online multimedia information. In this paper, we propose novel approaches to perform multimedia forensics using compact side information to reconstruct the processing history of a document. We refer to this as FASHION, standing for Forensic hASH for informatION assurance. Based on the Radon transform and scale space theory, the proposed forensic hash is compact and can effectively estimate the parameters of geometric transforms and detect local tampering that an image may have undergone. Forensic hash is designed to answer a broader range of questions regarding the processing history of multimedia data than the simple binary decision from traditional robust image hashing, and also offers more efficient and accurate forensic analysis than multimedia forensic techniques that do not use any side information.

    According to the literature, psychological assessment in forensic contexts is one of the most controversial application areas for clinical psychology. This paper presents a review of systematic judgment errors in the forensic field. Forty-six psychological reports written by psychologists, court consultants, have been analyzed with content analysis to identify typical judgment errors related to the following areas: (a) distortions in the attribution of causality, (b) inferential errors, and (c) epistemological inconsistencies. Results indicated that systematic errors of judgment, usually referred also as “the man in the street,” are widely present in the forensic evaluations of specialist consultants. Clinical and practical implications are taken into account. This article could lead to significant benefits for clinical psychologists who want to deal with this sensitive issue and are interested in improving the quality of their contribution to the justice system.

    Data are reported on 28 deaf individuals who were convicted, pled guilty, or have been charged and awaiting trial for murder. The unique forensic issues raised by these cases are discussed, and their clinical picture presented. A significant percentage of these deaf murderers and defendants had such severely limited communication skills in both English and American Sign Language that they lacked the linguistic ability to understand the charges against them and/or to participate in their own defense. As such, they were incompetent to stand trial, due not to mental illness or mental retardation, but to linguistic deficits. This form of incompetence poses a dilemma to the courts that remains unresolved. This same linguistic disability makes it impossible for some deaf suspects to be administered Miranda Warnings in a way comprehensible to them. This paper identifies the reasons for the communication problems many deaf persons face in court and offers remedial steps to help assure fair trials and police interrogations for deaf defendants. The roles and responsibilities of psychiatric and psychological experts in these cases are discussed. Data are provided on the etiology of the 28 individuals' hearing losses, psychiatric/psychological histories, IQs, communication characteristics, educational levels, and victim characteristics.

    The first technical discussions, held in 1958, on methods of verifying compliance with a treaty banning nuclear explosions, concluded that a monitoring system could be set up to detect and identify such explosions anywhere except underground: the difficulty with underground explosions was that there would be some earthquakes that could not be distinguished from an explosion. The development of adequate ways of discriminating between earthquakes and underground explosions proved to be difficult so that only in 1996 was a Comprehensive Nuclear Test Ban Treaty (CTBT) finally negotiated. Some of the important improvements in the detection and identification of underground tests—that is in forensic seismology—have been made by the UK through a research group at the Atomic Weapons Establishment (AWE). The paper describes some of the advances made in identification since 1958, particularly by the AWE Group, and the main features of the International Monitoring System (IMS), being set up to verify the Test Ban. Once the Treaty enters into force, then should a suspicious disturbance be detected the State under suspicion of testing will have to demonstrate that the disturbance was not a test. If this cannot be done satisfactorily the Treaty has provisions for on-site inspections (OSIs): for a suspicious seismic disturbance for example, an international team of inspectors will search the area around the estimated epicentre of the disturbance for evidence that a nuclear test really took place. Early observations made at epicentral distances out to 2,000 km from the Nevada Test Site showed that there is little to distinguish explosion seismograms from those of nearby earthquakes: for both source types the short-period (SP: ˜1 Hz) seismograms are complex showing multiple arrivals. At long range, say 3,000 10,000 km, loosely called teleseismic distances, the AWE Group noted that SP P waves—the most widely and well-recorded waves from underground explosions—were in

    Fatal starvation is a rare cause of death in industrialized countries. However, it may have major medicolegal importance if death results from the deliberate withholding of food, especially from infants. In such cases, the task of the forensic pathologist and the medical examiner, respectively, is to clarify the cause of death and give an expert opinion on the degree and duration of starvation. Several classification systems have been developed to estimate protein-energy malnutrition in developing countries. Simpler classifications, such as the Gomez classification, use the weight expected for the respective age group as the standard. However, smaller infants will be lighter, and therefore the classification may not be accurate in this case. Following the Waterlow classification, the extent of stunted growth (referring to growth retardation in cases of chronic malnutrition) is calculated using the ratio of the measured body height to that expected for the age. Using such classification systems, grading of stunting and wasting can be achieved and may greatly help in the assessment of a given child's nutritional status in legal cases. The application of the Waterlow classification to the authors' case material and previously published cases in the literature is herein demonstrated. The Waterlow classification is not only of importance for grading the final stage of fatal starvation, but also for the chronological development of the nutritional status if anthropometrical data have been repeatedly recorded from the affected individual in vivo.

    Mental disorders are among the most prevalent of chronic disorders, and a high prevalence of these disorders has been consistently found in jails and prisons. This study was a retrospective case series that described the population of adults charged with a criminal offense who were court ordered to undergo a psychiatric assessment within the Medical Legal Service in Santiago, Chile from 2005 to 2006. Characteristics were explored in order to better understand this population in light of the recent reforms in the judicial and health systems of Chile. Ninety percent of sampled individuals were male, primarily between the ages of 18-39 years. Seventy percent of the evaluations came from the pre-reformed judicial system and 30% were from the reformed system. Approximately 63% of evaluated offenders were considered to have a psychiatric pathology, the most common being the personality disorders. Of the evaluated offenders, approximately 84% were considered by a psychiatrist to be criminally responsible for their crime, 7% were regarded as having diminished criminal responsibility, 4% were considered to be not criminally responsible for their crime, and 4% were cases where criminal responsibility was not applicable. Profession status, municipality of residence, type of residence, ICD-10 diagnosis, treatment recommendation, and criminal responsibility were found to be significantly different between male and female evaluated offenders. Results from this investigation will contribute to knowledge about forensic psychiatry and mental health in Latin America, and will hopefully pave the way for more research and international comparisons.

  8. Information Assurance and Forensic Readiness

    Pangalos, Georgios; Katos, Vasilios

    Egalitarianism and justice are amongst the core attributes of a democratic regime and should be also secured in an e-democratic setting. As such, the rise of computer related offenses pose a threat to the fundamental aspects of e-democracy and e-governance. Digital forensics are a key component for protecting and enabling the underlying (e-)democratic values and therefore forensic readiness should be considered in an e-democratic setting. This position paper commences from the observation that the density of compliance and potential litigation activities is monotonically increasing in modern organizations, as rules, legislative regulations and policies are being constantly added to the corporate environment. Forensic practices seem to be departing from the niche of law enforcement and are becoming a business function and infrastructural component, posing new challenges to the security professionals. Having no a priori knowledge on whether a security related event or corporate policy violation will lead to litigation, we advocate that computer forensics need to be applied to all investigatory, monitoring and auditing activities. This would result into an inflation of the responsibilities of the Information Security Officer. After exploring some commonalities and differences between IS audit and computer forensics, we present a list of strategic challenges the organization and, in effect, the IS security and audit practitioner will face.

  10. System Support for Forensic Inference

    Digital evidence is playing an increasingly important role in prosecuting crimes. The reasons are manifold: financially lucrative targets are now connected online, systems are so complex that vulnerabilities abound and strong digital identities are being adopted, making audit trails more useful. If the discoveries of forensic analysts are to hold up to scrutiny in court, they must meet the standard for scientific evidence. Software systems are currently developed without consideration of this fact. This paper argues for the development of a formal framework for constructing “digital artifacts” that can serve as proxies for physical evidence; a system so imbued would facilitate sound digital forensic inference. A case study involving a filesystem augmentation that provides transparent support for forensic inference is described.

  11. Forensic Botany: Evidence and Analysis.

    PubMed

    Coyle, H M

    Forensic botany is the use of plant evidence in matters of law. While plant fragments are often collected as trace evidence, they are only occasionally identified using microscopy and are still more rarely assessed using molecular biology techniques for individualization and sourcing of a sample. There are many different methods useful for DNA typing of plants; this review focuses on those techniques (DNA sequencing, STR, AFLP, RAPD) most relevant to the forensic science community and on those methods currently in practice. Plant evidence is commonly associated with homicides, with clandestine graves, as trace pollen on clothing, vehicles, or packaging, or in the transport of illicit drugs. DNA can be especially useful for the identification of minute quantity of samples, for differentiation of plants that lack distinguishing morphological features, and for generating a unique identifier for associative forensic evidence.

    With the increase in the number of digital crimes and in their sophistication, High Performance Computing (HPC) is becoming a must in Digital Forensics (DF). According to the FBI annual report, the size of data processed during the 2010 fiscal year reached 3,086 TB (compared to 2,334 TB in 2009) and the number of agencies that requested Regional Computer Forensics Laboratory assistance increasing from 689 in 2009 to 722 in 2010. Since most investigation tools are both I/O and CPU bound, the next-generation DF tools are required to be distributed and offer HPC capabilities. The need for HPC is even more evident in investigating crimes on clouds or when proactive DF analysis and on-site investigation, requiring semi-real time processing, are performed. Although overcoming the performance challenge is a major goal in DF, as far as we know, there is almost no research on HPC-DF except for few papers. As such, in this work, we extend our work on the need of a proactive system and present a high performance automated proactive digital forensic system. The most expensive phase of the system, namely proactive analysis and detection, uses a parallel extension of the iterative z algorithm. It also implements new parallel information-based outlier detection algorithms to proactively and forensically handle suspicious activities. To analyse a large number of targets and events and continuously do so (to capture the dynamics of the system), we rely on a multi-resolution approach to explore the digital forensic space. Data set from the Honeynet Forensic Challenge in 2001 is used to evaluate the system from DF and HPC perspectives.

    Although it is an intrinsic part of all medical practice forensic medicine often is either unrecognized as such or is consciously or subconsciously evaded. The failure to apply some rather basic and simple forensic principles that only the physician is capable of doing may result in problems to the patient ranging from frustration to near catastrophe. For physicians who are reasonably well equipped to understand the legal system, the successful conclusion of a legal case, including, sometimes, an appearance in court, can be stimulating and interesting.

    Douglas, A.

    2007-01-01

    The first technical discussions, held in 1958, on methods of verifying compliance with a treaty banning nuclear explosions, concluded that a monitoring system could be set up to detect and identify such explosions anywhere except underground: the difficulty with underground explosions was that there would be some earthquakes that could not be distinguished from an explosion. The development of adequate ways of discriminating between earthquakes and underground explosions proved to be difficult so that only in 1996 was a Comprehensive Nuclear Test Ban Treaty (CTBT) finally negotiated. Some of the important improvements in the detection and identification of underground tests—that is in forensic seismology—have been made by the UK through a research group at the Atomic Weapons Establishment (AWE). The paper describes some of the advances made in identification since 1958, particularly by the AWE Group, and the main features of the International Monitoring System (IMS), being set up to verify the Test Ban. Once the Treaty enters into force, then should a suspicious disturbance be detected the State under suspicion of testing will have to demonstrate that the disturbance was not a test. If this cannot be done satisfactorily the Treaty has provisions for on-site inspections (OSIs): for a suspicious seismic disturbance for example, an international team of inspectors will search the area around the estimated epicentre of the disturbance for evidence that a nuclear test really took place. Early observations made at epicentral distances out to 2,000 km from the Nevada Test Site showed that there is little to distinguish explosion seismograms from those of nearby earthquakes: for both source types the short-period (SP: ˜1 Hz) seismograms are complex showing multiple arrivals. At long range, say 3,000 10,000 km, loosely called teleseismic distances, the AWE Group noted that SP P waves—the most widely and well-recorded waves from underground explosions—were in

    This is an introductory study of forensic podiatry. To elevate forensic podiatry to the level of forensic odontology and forensic anthropology, the podiatric medical profession must begin educational programs and research. A system for monitoring the activities of podiatrists involved in forensic medicine must be established to ensure that the high degree of integrity to which the profession is committed is maintained. By following these guidelines, the author believes that sometime in the future a podiatrist will be on the staff of every major police department in the country. At that point, the podiatric medical profession will have achieved unsurpassed status, recognition, and prestige. PMID:2664129

    While some individuals have referred to digital forensics as an art, the literature of the discipline suggests a trend toward the formalization of digital forensics as a forensic science. Questions about the quality of digital evidence and forensic soundness continue to be raised by researchers and practitioners in order to ensure the trustworthiness of digital evidence and its value to the courts. This paper reviews the development of digital forensic models, procedures and standards to lay a foundation for the discipline. It also points to new work that provides validation models through a complete mapping of the discipline.

    This paper introduces a control framework for digital forensics. It proposes a taxonomy for control objectives, categorized within the phases of the digital forensic process: planning and preparation, incident response, investigation and juridical/evidentiary. Using the taxonomy as a basis, a digital forensic reference framework, consisting of control groupings, control objectives and detailed control objectives, is defined. The control framework is intended to provide a sound theoretical basis for digital forensics as well as a reference framework for digital forensics governance within organizations.

    In recognition of Howard Zonana's contributions, I take stock of the progress of the field of forensic psychiatry over three decades. As forensic psychiatrists, you are the voice of psychiatry in the law and the interpreter of law to your colleagues in psychiatry. I offer provisional impressions of your collective accomplishments under three themes: expertise, influence, and integrity. First, you have established and nurtured the expertise and authority of forensic psychiatry, which has become increasingly evidence-based and reflects a prudent sense of humility. Second, you have had a significant influence on the design and daily application of mental health law in both criminal and civil spheres. Through the American Academy of Psychiatry and the Law (AAPL) and relevant components of the American Psychological Association, you have been a strong and effective advocate for protecting both the needs and rights of people with mental illness and have had demonstrable influence in the Supreme Court as well as at the grassroots. Finally, you have nurtured and protected the ethical integrity of the profession in the face of ever-increasing challenges, due in no small measure to the habits of ethical reflection that Howard Zonana has modeled and taught over the course of his extraordinary career.

    PubMed

    Money, J

    1990-01-01

    Forensic sexology is not synonymous with either forensic psychiatry or forensic psychology. It is a specialty in its own right, and is needed in the courtroom. Paraphilic sex offenders on trial are misrepresented as being, by their own choice, psychopathic or sociopathic deviates. They are unable to explain their paraphilic criminality to either themselves or society. In a case of serial rape and serial lust murder here presented, the contributory causes are examined and differentiated as hereditary predisposition, hormonal functioning; pathological relationships, sexual abuse; and syndrome overlap with bipolar disorder, schizoid disorder, antisocial personality disorder, epilepsy, and multiple personality. The precipitating causes were differentiated as childhood head injuries, and adult head injury at age 20. Left impact trauma and sexological trauma were sequelae of the adult injury. The full range of diagnostic resources was not available for a prisoner on death row. Capital punishment has not prevented the reemergence in each new generation of serial rape and serial lust murder as an epidemiological, public health problem. Punishment is an ineffectual substitute for epidemiological research into cause, effect, and prevention. PMID:2327516

    Veterinary forensic pathology is emerging as a distinct discipline, and this special issue is a major step forward in establishing the scientific basis of the discipline. A forensic necropsy uses the same skill set needed for investigations of natural disease, but the analytical framework and purpose of forensic pathology differ significantly. The requirement of legal credibility and all that it entails distinguishes the forensic from routine diagnostic cases. Despite the extraordinary depth and breadth of knowledge afforded by their training, almost 75% of veterinary pathologists report that their training has not adequately prepared them to handle forensic cases. Many veterinary pathologists, however, are interested and willing to develop expertise in the discipline. Lessons learned from tragic examples of wrongful convictions in medical forensic pathology indicate that a solid foundation for the evolving discipline of veterinary forensic pathology requires a commitment to education, training, and certification. The overarching theme of this issue is that the forensic necropsy is just one aspect in the investigation of a case of suspected animal abuse or neglect. As veterinary pathologists, we must be aware of the roles filled by other veterinary forensic experts involved in these cases and how our findings are an integral part of an investigation. We hope that the outcome of this special issue of the journal is that veterinary pathologists begin to familiarize themselves with not only forensic pathology but also all aspects of veterinary forensic science.

    Bell, Chris

    2006-10-16

    Forensic intelligence can be viewed as comprising two parts, one directly concerning intelligence delivery in forensic casework, the other considering performance aspects of forensic work, loosely termed here as business intelligence. Forensic casework can be viewed as processes that produce an intelligence product useful to police investigations. Traditionally, forensic intelligence production has been confined to discipline-specific activity. This paper examines the concepts, processes and intelligence products delivered in forensic casework, the information repositories available from forensic examinations, and ways to produce within- and across-discipline casework correlations by using information technology to capitalise on the information sets available. Such analysis presents opportunities to improve forensic intelligence services as well as challenges for technical solutions to deliver appropriate data-mining capabilities for available information sets, such as digital photographs. Business intelligence refers primarily to examination of efficiency and effectiveness of forensic service delivery. This paper discusses measures of forensic activity and their relationship to crime outcomes as a measure of forensic effectiveness. PMID:16893621

    Background In Japan, the legislation directing treatment of offenders with psychiatric disorders was enacted in 2005. Neuropsychological impairment is highly related to functional outcomes in patients with psychiatric disorders, and several studies have suggested an association between neuropsychological impairment and violent behaviors. However, there have been no studies of neuropsychological impairment in forensic patients covered by the Japanese legislation. This study is designed to examine the neuropsychological characteristics of forensic patients in comparison to healthy controls and to assess the relationship between neuropsychological impairment and violence risk. Methods Seventy-one forensic patients with psychiatric disorders and 54 healthy controls (matched by age, gender, and education) were enrolled. The CogState Battery (CSB) consisting of eight cognitive domains, the Iowa Gambling Task (IGT) to test emotion-based decision making, and psychological measures of violence risk including psychopathy were used. Results Forensic patients exhibited poorer performances on all CSB subtests and the IGT than controls. For each group, partial correlational analyses indicated that poor IGT performance was related to psychopathy, especially antisocial behavior. In forensic patients, the CSB composite score was associated with risk factors for future violent behavior, including stress and noncompliance with remediation attempts. Conclusion Forensic patients with psychiatric disorders exhibit a wide range of neuropsychological impairments, and these findings suggest that neuropsychological impairment may increase the risk of violent behavior. Therefore, the treatment of neuropsychological impairment in forensic patients with psychiatric disorders is necessary to improve functional outcomes as well as to prevent violence. PMID:26824701

    A typical incident response pits technicians against networks that aren't prepared forensically. [1, 2] If practitioners do consider collecting network forensic data, they face a choice between expending extraordinary effort (time and money) collecting forensically sound data, or simply restoring the network as quickly as possible. In this context, the concept of organizational network forensic readiness has emerged. This paper proposes a methodology for "operationalizing" organizational network forensic readiness. The methodology, and the theoretical analysis that led to its development, are offered as a conceptual framework for thinking about more efficient, proactive approaches to digital forensics on networks.

    In this paper the insights and results are presented of a long term and ongoing improvement effort within the Netherlands Forensic Institute (NFI) to establish a valuable innovation programme. From the overall perspective of the role and use of forensic science in the criminal justice system, the concepts of Forensic Information Value Added (FIVA) and Forensic Information Value Efficiency (FIVE) are introduced. From these concepts the key factors determining the added value of forensic investigations are discussed; Evidential Value, Relevance, Quality, Speed and Cost. By unravelling the added value of forensic science and combining this with the future needs and scientific and technological developments, six forensic grand challenges are introduced: i) Molecular Photo-fitting; ii) chemical imaging, profiling and age estimation of finger marks; iii) Advancing Forensic Medicine; iv) Objective Forensic Evaluation; v) the Digital Forensic Service Centre and vi) Real time In-Situ Chemical Identification. Finally, models for forensic innovation are presented that could lead to major international breakthroughs on all these six themes within a five year time span. This could cause a step change in the added value of forensic science and would make forensic investigative methods even more valuable than they already are today. PMID:24630329

    In April 2002, 17 American prisoners of war (POWs) and 37 of their family members brought an action in federal district court in Washington, D.C., against the Republic of Iraq, Saddam Hussein, and the Iraqi Intelligence Service for torture the POWs alleged they endured in 1991, following their capture during Operation Desert Storm. This action was the first in which prisoners of war sued a sovereign state for torture. As part of their case, the plaintiffs claimed psychological damage, and presented forensic evaluations of the POWs and their families in support. This article will address the novel questions and problems in this case, including: the legal context of the action; the logistical difficulties in evaluating a large number of plaintiffs in diverse locations; the challenges of establishing psychological injury in military personnel; the relationship between the forensic findings and the literature on POWs; the potential bias and secondary trauma experienced by the examiners; and the outcome of the action and prospects for similar actions in the future.

    Animal sexual abuse (ASA) involves harm inflicted on animals for the purposes of human sexual gratification and includes such terms as bestiality, zoophilia, zoosadism, animal sexual assault, and others. The prevalence of ASA is not known, although it may be more common than is currently perceived. Veterinarians have the skills required to identify and document cases of ASA. This article reviews the terminology, legal definitions and forms of ASA, and its social and psychological context. An investigative approach is outlined, including an alternate light source examination; collection of swabs for DNA analysis; sampling vaginal washes, rectal washes, and toenails for trace evidence and biologic analyses; radiographic studies; and a complete forensic necropsy, including histopathology. Gross lesions identified in ASA victims include injuries to the anus, rectum, penis, scrotum, nipples, and vagina; the presence of foreign bodies; and abrasions, bruising, and other evidence of nonaccidental injury. Specialized procedures, including examination using alternate light sources and screening tests to identify human seminal fluid within samples from ASA victims, are of potential value but have not been validated for use in animals.

    , soil) adhering to a meteorite are samples of the actual physical environment in which the meteorite rested. Adhesion may derive from chemical cementation (incl. rust from the meteorite), biologic activity (incl. desert varnish?), or impact processes [2]. Given the wide diversity of geological materials and processes on the Earth, adhering geological materials may be useful forensic tools. For instance, fall in a volcanic terrane may be inconsistent with adhering sediments of clean quartz sand. Biologic matter on meteorites includes animal and vegetable matter mixed with the adhering geological materials, lichens and other plants growing in place, and purposefully attached animal matter (e.g. insect eggs). The most useful biological data may be provided by pollen, which can often be referred unambiguously to genera and species of plants. For example, sediments adhering to meteorites from the central Nullabor Plain (W. Australia) are different from sediments from the Plain's margin in S. Australia. Sediment on meteorites from the central Nullabor (e.g. Mundrabilla) lacks quartz sand and consists almost entirely of clay-sized particles, consistent with derivation from the local saprolitic soil. Sediment on meteorites from the eastern Nullabor (e.g. Hughes and Cook, S.A.) contains a significant fraction of quartz sand, 1/4- to 1/2-mm grains, probably blown from the Great Victoria Desert to the north and northwest. However, sedimentologic data alone may be misleading. For instance, sediments adhering to Nuevo Mercurio stones (H5; Zacatecas, Mexico) are clay-sized and lack coarser material. But sediment on Nuevo Mercurio (b), a ureilite found in the Nuevo Mercurio strewn field, consists of quartz sand and clay pellets, 1/4 to 1/2 mm diameter. Clearly, local environments may affect the character of sediment adhering to a meteorite, and careful detailed study may be required to determine whether a meteorite has been transported.

    The main aim of Forensic Entomology has always been, and is today, to establish the time of death (P.M.I.: Postmortem Period) or, more exactly, how long a carrion has been exposed in the environment. Most of the invertebrate fauna occurring on corpses consists of insects (mostly Diptera and Coleoptera). They are selectively attracted by the decomposing status of the carrion, and form complex communities or biocenosis within necrophagous or sarcophagous species and their predators, parasites and parasitoids, competing each one another. The rapid and continuos changes of the micro-ecosystem (the body), until its breakdown, does not permit the achievement of a steady state or an equilibrium in the animal communities. These continuous modifications give us the possibility to estimate when (and where) the death has occurred, by the identification of the species feeding on the corpse, the knowledge of their life history, and the length of each stage of their cycle at varying the temperature and the other abiotic factors, external to the carrion ecosystem. The P.M.I. today is still largely based on the tables of faunal succession on human cadavers recognised by Mégin in 1894, with few changes proposed by Authors from other countries. In the last years, however, it happens more and more often, that the natural communities are subverted by the presence of allocton species, which can compete, predate or parasite the most common local sarcophagous insects, modifying, this way, the succession waves and the trophic nets. The immission in the environment of foreign species may be voluntary or casual, but in any case is due to anthropic activities. The voluntary immission happens when some species, employed in the biological struggle against pest or dangerous insects, for pollination of allocton plants, or for other commercial utilities, are beyond man's control and swarm onto the environment; the casual spread is due to the globalisation phenomenon, that distributes the "little

    Microorganisms have been used as weapons in criminal acts, most recently highlighted by the terrorist attack using anthrax in the fall of 2001. Although such ''biocrimes'' are few compared with other crimes, these acts raise questions about the ability to provide forensic evidence for criminal prosecution that can be used to identify the source of the microorganisms used as a weapon and, more importantly, the perpetrator of the crime. Microbiologists traditionally investigate the sources of microorganisms in epidemiological investigations, but rarely have been asked to assist in criminal investigations. A colloquium was convened by the American Academy of Microbiology in Burlington, Vermont, on June 7-9, 2002, in which 25 interdisciplinary, expert scientists representing evolutionary microbiology, ecology, genomics, genetics, bioinformatics, forensics, chemistry, and clinical microbiology, deliberated on issues in microbial forensics. The colloquium's purpose was to consider issues relating to microbial forensics, which included a detailed identification of a microorganism used in a bioattack and analysis of such a microorganism and related materials to identify its forensically meaningful source--the perpetrators of the bioattack. The colloquium examined the application of microbial forensics to assist in resolving biocrimes with a focus on what research and education are needed to facilitate the use of microbial forensics in criminal investigations and the subsequent prosecution of biocrimes, including acts of bioterrorism. First responders must consider forensic issues, such as proper collection of samples to allow for optimal laboratory testing, along with maintaining a chain of custody that will support eventual prosecution. Because a biocrime may not be immediately apparent, a linkage must be made between routine diagnosis, epidemiological investigation, and criminal investigation. There is a need for establishing standard operating procedures and training to

    Two experiments were performed to test the relevance of bryophyte (Plantae, Bryophyta) material for forensic studies. The first experiment was conducted to reveal if, and how well, plant fragments attach to footwear in general. In the test, 16 persons walked outdoors wearing rubber boots or hiking boots. After 24h of use outdoors the boots were carefully cleaned, and all plant fragments were collected. Afterwards, all plant material was examined to identify the species. In the second experiment, fresh material of nine bryophyte species was kept in a shed in adverse conditions for 18 months, after which DNA was extracted and subjected to genotyping to test the quality of the material. Both experiments give support for the usability of bryophyte material in forensic studies. The bryophyte fragments become attached to shoes, where they remain even after the wearer walks on a dry road for several hours. Bryophyte DNA stays intact, allowing DNA profiling after lengthy periods following detachment from the original plant source. Based on these experiments, and considering the fact that many bryophytes are clonal plants, we propose that bryophytes are among the most usable plants to provide botanical evidence for forensic investigations.

    2013-05-01

    The finding of a mummified body raises many problems, also because of the limits of the medico-legal investigations in case of mummification. Psychological autopsy and behavioral analysis have demonstrated a significant impact in case of equivocal death. The mummified corpse of a woman was found sealed in a wardrobe during the death investigation of a 36-year-old man, later discovered to be the woman's son. The woman's corpse was well preserved and no external injuries were found. Autopsy could not ascertain the cause of death. The state of the premises and the writings on the walls offered an opportunity to investigate the man's psychological profile and to better understand how the events might have taken place. The role of an accurate investigative analysis of the crime scene is a cornerstone of forensic pathology and the case presented underlies the importance of an interdisciplinary approach in forensic sciences.

    A team of Finnish forensic experts performed investigations of alleged mass graves in Kosovo under the mandate of the European Union (EU). Human skeletal remains from two locations were examined. The remains contained three almost complete skeletons, and individual bones and bone fragments, part of which were burned. Injuries, pathological changes, and findings for identification purposes were examined and documented using standard methods of forensic pathology and osteology. Gunshot injuries were found in some cases, but reliable determination of the cause and manner of death was not possible. A discrepancy arose between the number of victims reported in information received from the presiding district court, and results of the investigations. The estimation of the minimum number of victims was mostly acquired by DNA analysis. PMID:11566420

    Im draws a parallel between the neurobiology of individuals with autism spectrum disorder (ASD) and that of trauma survivors, to explain why individuals with ASD may be more vulnerable to trauma as a risk factor for violence. This commentary raises questions about how we use this information in a forensic context, including its potential misuses. It urges caution in not overstating the data before we have a more nuanced understanding of how our neural circuitry influences specific behaviors and mental states, while not allowing the science to advance faster than we can harness it, overstepping its bounds in decisions we make regarding fairness and justice. It raises these concerns against a backdrop of the diametrically opposed assumptions about human behavior embraced by the two disciplines, mental health and the law, that come together in the forensic arena.

    Taste disorders can a rise from lesions of peripheral receptors, taste control pathways or cortical area involvement. Among peripheral lesions, trauma of the tongue and oropharynx are the most common. Iatrogenic lesions of facial and glossopharingeal nerves are very important in Forensic Medicine, while there are different opinions about taste alterations due to head injuries; hypogeusia associated to smell disorders are found in 0.4-0.5% of patient after head trauma with good prognosis (90% healing) while qualitative disorders are more common (30%). The Authors describe clinical methodologies for taste evaluation and their application in Forensic Medicine. Forensic estimation of taste disorders con be classified by two main groups: study of cause relation between the occurrence and damage and quantitative valuation of the damage in three different juridical ambits: Penal, Civil, Insurance and foresight. In Penal Right taste damages could be classified among personal lesion crimes and can be classified as serious (permanent injury of taste) ore very serious (complete lost of taste function). Italian Legislation equipare the 5 sense organs. In Civil Right evaluation the so-called "biologic damage" and working ability are considered; this means very different evaluations. In the most recent baremes, generic damage is estimated by different Authors from 0 to 10% while with regard to specific working capacity, common evaluation criteria does not exist. In Insurance taste disorders evaluation is based only on working ability and not on biologic damage. In the previdenzial ambit, taste disorders are not even included in the most recent tables of permanent invalidity estimation. The Authors propose new and more efficacious valutation criteria for taste disorders in all ambits, hoping for more interest in the Forensic aspects of taste, a too often forgotten sensory function.

    The established importance of Forensic Dentistry for human identification, mainly when there is little remaining material to perform such identification (e.g., in fires, explosions, decomposing bodies or skeletonized bodies), has led dentists working with forensic investigation to become more familiar with the new molecular biology techniques. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article presents a literature review referring to the main studies on Forensic Dentistry that involve the use of DNA for human identification, and makes an overview of the evolution of this technology in the last years, highlighting the importance of molecular biology in forensic sciences.

    2011-12-01

    Forensic entomology is the science of collecting and analysing insect evidence to aid in forensic investigations. Its main application is in the determination of the minimum time since death in cases of suspicious death, either by estimating the age of the oldest necrophagous insects that developed on the corpse, or by analysing the insect species composition on the corpse. In addition, toxicological and molecular examinations of these insects may help reveal the cause of death or even the identity of a victim, by associating a larva with its last meal, for example, in cases where insect evidence is left at a scene after human remains have been deliberately removed. Some fly species can develop not only on corpses but on living bodies too, causing myiasis. Analysis of larvae in such cases can demonstrate the period of neglect of humans or animals. Without the appropriate professional collection of insect evidence, an accurate and convincing presentation of such evidence in court will be hampered or even impossible. The present paper describes the principles and methods of forensic entomology and the optimal techniques for collecting insect evidence. PMID:21213072

    2004-05-01

    In an effort to characterize research efforts in forensic pathology, a questionnaire was sent to a representative of each of the 14 academic medical centers that employ full-time faculty forensic pathologists. Responses were received from all 14 (100%) of the institutions queried, representing a total of 39 forensic pathology faculty positions; 21 positions were tenure track and 18 positions were clinical or other tracks. Of the 39 positions, 25 positions (64%) at 10 institutions required some degree of research or scholarly output. Of the 25 forensic pathologists with a research imperative, only 3 (12%) were principal investigators or co-investigators on funded forensic pathology-based projects. The major limitation cited by respondents on the performance of forensic pathology research was the lack of protected time from service responsibilities. Fellowship training in forensic pathology was available at 6 of the 14 respondent institutions. Of these institutions, 4 (67%) had a research requirement for trainees, and 4 (67%) provided research training. In conclusion, very few US medical schools currently employ full-time faculty forensic pathologists. Of these, only a small number of institutions prioritize research by these faculty members. Scant federal funds are available to support research in forensic pathology. Few forensic pathology fellowship programs provide research training. To achieve a robust research agenda in forensic pathology that is sufficient to support the needs of the criminal justice and public health systems will require a paradigm shift in the medicolegal death investigative system and investment by federal agencies.

    Almost no literature addresses treatment planning for the forensic psychiatric patient. In the absence of such guidance, recovery-oriented multifocal treatment planning has been imported into forensic mental health systems from community psychiatric settings, despite the fact that conditions of admission and discharge are vastly different for forensic psychiatry inpatients. We propose that instead of focusing on recovery, forensic treatment planning should prioritize forensic outcomes, such as restoration of trial competence or mitigation of violence risk, as the first steps in a continuum of care that eventually leads to the patient's ability to resolve forensic issues and return to the community for recovery-oriented care. Here we offer a model for treatment planning in the forensic setting. PMID:25801440

    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

    Karie, Nickson M; Venter, Hein S

    2015-07-01

    Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well-defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area.

    The challenges met by the psychiatrist and the psychologist and the difficulties in providing forensic-psychiatry and forensic-psychology opinions have been reviewed, based on examples. The studied patient was hospitalised 10 times and the forensic-psychiatry opinion passed 15 times during the judiciary process. Different psychiatric diagnoses were made and different soundness of mind were passed. The psychiatric health status were expresses by professors of psychiatry who did not participate directly in passing the forensic-psychiatry opinion. The studied patient was examined by other specialists and assessed by certificating medical doctors with the aim of getting disability pension benefits. The effect of medical certificates and testimonials from different medical doctors were analysed. Analysing this example, revealed the problem of proper formulation of content of medical documents to support the medical diagnosis and declared soundness of mind during the passing of forensic-psychiatry opinion. The doctors treating the patients and doctors passing opinion on the treated patient had a different assessment of the diagnoses and soundness of mind for the studied patients. Irrespective of the immediate aim of the examinations, all professionals providing assessment should mind the consequences of opinions passed by them and especially, the possibility of the opinion being used by the subject to prolong the judiciary process or even avoid legal responsibility. The independence (sovereignty) of the expert requires consideration in the context of prior multiple forensic-psychiatry opinion leaders in the field of psychiatry and the need for the expert to assume an attitude towards these opinions.

    2010-02-01

    Over the past twenty years, DNA analysis has revolutionized forensic science, and has become a dominant tool in law enforcement. Today, DNA evidence is key to the conviction or exoneration of suspects of various types of crime, from theft to rape and murder. However, the disturbing possibility that DNA evidence can be faked has been overlooked. It turns out that standard molecular biology techniques such as PCR, molecular cloning, and recently developed whole genome amplification (WGA), enable anyone with basic equipment and know-how to produce practically unlimited amounts of in vitro synthesized (artificial) DNA with any desired genetic profile. This artificial DNA can then be applied to surfaces of objects or incorporated into genuine human tissues and planted in crime scenes. Here we show that the current forensic procedure fails to distinguish between such samples of blood, saliva, and touched surfaces with artificial DNA, and corresponding samples with in vivo generated (natural) DNA. Furthermore, genotyping of both artificial and natural samples with Profiler Plus((R)) yielded full profiles with no anomalies. In order to effectively deal with this problem, we developed an authentication assay, which distinguishes between natural and artificial DNA based on methylation analysis of a set of genomic loci: in natural DNA, some loci are methylated and others are unmethylated, while in artificial DNA all loci are unmethylated. The assay was tested on natural and artificial samples of blood, saliva, and touched surfaces, with complete success. Adopting an authentication assay for casework samples as part of the forensic procedure is necessary for maintaining the high credibility of DNA evidence in the judiciary system. PMID:20129467

  15. Accreditation standards for undergraduate forensic science programs

    NASA Astrophysics Data System (ADS)

    Miller, Marilyn Tebbs

    Undergraduate forensic science programs are experiencing unprecedented growth in numbers of programs offered and, as a result, student enrollments are increasing. Currently, however, these programs are not subject to professional specialized accreditation. This study sought to identify desirable student outcome measures for undergraduate forensic science programs that should be incorporated into such an accreditation process. To determine desirable student outcomes, three types of data were collected and analyzed. All the existing undergraduate forensic science programs in the United States were examined with regard to the input measures of degree requirements and curriculum content, and for the output measures of mission statements and student competencies. Accreditation procedures and guidelines for three other science-based disciplines, computer science, dietetics, and nursing, were examined to provide guidance on accreditation processes for forensic science education programs. Expert opinion on outcomes for program graduates was solicited from the major stakeholders of undergraduate forensic science programs-forensic science educators, crime laboratory directors, and recent graduates. Opinions were gathered by using a structured Internet-based survey; the total response rate was 48%. Examination of the existing undergraduate forensic science programs revealed that these programs do not use outcome measures. Of the accreditation processes for other science-based programs, nursing education provided the best model for forensic science education, due primarily to the balance between the generality and the specificity of the outcome measures. From the analysis of the questionnaire data, preliminary student outcomes, both general and discipline-specific, suitable for use in the accreditation of undergraduate forensic science programs were determined. The preliminary results were reviewed by a panel of experts and, based on their recommendations, the outcomes

  17. Clinical myths of forensic neuropsychology.

    PubMed

    Greiffenstein, Manfred F

    2009-02-01

    Clinical myths and lore are unfounded beliefs that still influence practice decisions. I examine the validity of six beliefs commonly encountered in forensic neuropsychology practice: the admissibility of test batteries; avoidance of practice effects; forewarning insures good effort; average deficits in bright persons; 15% chronic impairment in mild brain injury; and examiner bias causing malingering. I show these beliefs are invalid because of material misunderstandings of case law and literature, falsification by empirical findings, and lack of authoritative sources. The benefits, costs, and persistence of clinical myths are discussed. PMID:18609338

  20. Tetrahydrocannabinols in clinical and forensic toxicology.

    PubMed

    Kochanowski, Maciej; Kała, Maria

    2005-01-01

    Cannabinoids are the natural constituents of marihuana (cannabis). The main of them are delta9-tetrahydrocannabinol (9THC)--psychoactive agent, cannabinol (CBN) and cannabidiol (CBD). Cannabis is administered either by smoking or orally. 9THC potency and duration of action as well as its and two of its major metabolites concentrations in organism highly depend on the route of administration. A single active dose of 9THC is estimated on 520 mg. 9THC is rapidly metabolised. It is hydroxylated to an active metabolite, I1 -hydroxy-delta9-tetrahydro-cannabinol (11-OH-THC), then oxidised to an inactive 11-nor-9-carboxy-delta9-tetrahydrocannabinol (THCCOOH), which is conjugated with glucuronic acid and predominantly excreted in the urine. The maximum psychological effect persists for 4-6 h after administration despite of very low 9THC blood concentrations. 9THC plasma concentration declined to values of 2-3 ng/ml during 3-4 h after smoking. Such a low concentration of the active compound in human organism create a demand for use of sensitive analytical methods for detection and determination of 9THC and its metabolites. The most effective techniques for 9THC and related compounds determination in biological material are chromatographic ones (gas and liquid) with mass spectrometric detection and different ionization modes. 9THC and its two metabolites (11-OH-THC and THCCOOH) are present in blood and hair, 9THC in saliva, and THCCOOH in urine. 9THC and related compounds are determined in autopsy material, although deaths by overdose of cannabis are exceptionally rare. Fatalities happen most often after intravenous injection of hashish oil. 9THC and its metabolites determination in different biological materials gives the basis for a wide interpretation of analytical results for clinical and forensic toxicology purposes.

    The field of microbial forensics has recently sought to develop methods to discern biological signatures to indicate production methods for biological agents. Viral agents have received less attention to date. Their obligate propagation in living cells makes purification from cellular material a challenge. This leads to potential carryover of protein-rich signature of their production system. Here we have explored a proteomic analysis of Vaccinia virus as a model poxvirus system in which to compare samples of virus propagated in different cell lines and subjected to different purification schemes. The proteomic data sets indicated viral, host cell and culture medium proteins, and several layers of data analysis were applied to build confidence in the peptide identification and capture information on the taxonomic utility of each. The analysis showed clear shifts in protein profiles with virus purification, with successive gradient purification steps showing different levels of viral protein enrichment. Peptides from cellular proteins, including those present in purified virus preparations, provided signatures which enabled discrimination of cell line substrates, including distinguishing between cells derived from different primate species. The ability to discern multiple aspects of viral production demonstrates the potential value of proteomic analysis as tool for microbial forensics.

  3. Vocal Forgery in Forensic Sciences

    NASA Astrophysics Data System (ADS)

    Perrot, Patrick; Morel, Mathieu; Razik, Joseph; Chollet, Gérard

    This article describes techniques of vocal forgery able to affect automatic speaker recognition system in a forensic context. Vocal forgery covers two main aspects: voice transformation and voice conversion. Concerning voice transformation, this article proposes an automatic analysis of four specific disguised voices in order to detect the forgery and, for voice conversion, different ways to automatically imitate a target voice. Vocal forgery appears as a real and relevant question for forensic expertise. In most cases, criminals who make a terrorist claim or a miscellaneous call, disguise their voices to hide their identity or to take the identity of another person. Disguise is considered in this paper as a deliberate action of the speaker who wants to conceal or falsify his identity. Different techniques exist to transform one’s own voice. Some are sophisticated as software manipulation, some others are simpler as using an handkerchief over the mouth. In voice transformation, the presented work is dedicated to the study of disguise used in the most common cases. In voice conversion, different techniques will be presented, compared, and applied on an original example of the French President voice.

    Electron microanalysis in forensic practice ranks among basic applications used in investigation of traces (latents, stains, etc.) from crime scenes. Applying electron microscope allows for rapid screening and receiving initial information for a wide range of traces. SEM with EDS/WDS makes it possible to observe topography surface and morphology samples and examination of chemical components. Physical laboratory of the Institute of Criminalistics Prague use SEM especially for examination of inorganic samples, rarely for biology and other material. Recently, possibilities of electron microscopy have been extended considerably using dual systems with focused ion beam. These systems are applied mainly in study of inner micro and nanoparticles , thin layers (intersecting lines in graphical forensic examinations, analysis of layers of functional glass, etc.), study of alloys microdefects, creating 3D particles and aggregates models, etc. Automated mineralogical analyses are a great asset to analysis of mineral phases, particularly soils, similarly it holds for cathode luminescence, predominantly colour one and precise quantitative measurement of their spectral characteristics. Among latest innovations that are becoming to appear also at ordinary laboratories are TOF - SIMS systems and micro Raman spectroscopy with a resolution comparable to EDS/WDS analysis (capable of achieving similar level as through EDS/WDS analysis).

  5. Forensic Analysis of Compromised Computers

    Wolfe, Thomas

    2004-01-01

    Directory Tree Analysis File Generator is a Practical Extraction and Reporting Language (PERL) script that simplifies and automates the collection of information for forensic analysis of compromised computer systems. During such an analysis, it is sometimes necessary to collect and analyze information about files on a specific directory tree. Directory Tree Analysis File Generator collects information of this type (except information about directories) and writes it to a text file. In particular, the script asks the user for the root of the directory tree to be processed, the name of the output file, and the number of subtree levels to process. The script then processes the directory tree and puts out the aforementioned text file. The format of the text file is designed to enable the submission of the file as input to a spreadsheet program, wherein the forensic analysis is performed. The analysis usually consists of sorting files and examination of such characteristics of files as ownership, time of creation, and time of most recent access, all of which characteristics are among the data included in the text file.

    2005-10-01

    The effects of an intramural cognitive-behavioral treatment for forensic inpatients with personality disorders in a high-security hospital were examined. Treatment was aimed at modifying maladaptive coping and social skills, at enhancing social awareness, at reducing egoistic and oppositional behaviors, and at reducing psychological complaints. The patients, who all had committed serious crimes (violence, arson, sexual offences), participated voluntarily in the study. A total of 39 patients started the study, but during the course of the study, several patients dropped out because of several reasons. Patients as a group showed significant improvements over time on psychopathological symptoms, personality traits, and coping. A significant decrease of oppositional behaviors was reported by the staff. Though the patients improved well at the group level, only a minority of patients showed reliable change over time at the individual level. The meaning of the results in relation to treatment are discussed. PMID:16260485

    Burgess, Christiana J.

    Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

    2013-01-01

    The National Academy of Sciences (2009) published a review charting several key recommendations on strengthening the forensic sciences as an entity as part of an initiative put forth by the USA Congress to streamline and improve the quality of the forensic sciences and their impact on the judiciary process. Although the review was not totally inclusive, many of its sentiments have permeated into all the forensic sciences. The following paper is designed to determine who is practicing the science of forensic entomology, and in what capacity, by questioning practicing forensic entomologists about the type of education obtained, their countries' standards and accreditation processes, as well as general demographic information such as age and gender. A 28-question survey was sent out to 300 forensic entomologists worldwide in 2009. Of the 70 respondents, 80% had a formal education (either Masters or PhD), and 66% published their research. Approximately 50% of respondents were involved in the delivery of expert evidence and writing up case reports, and countries were actively involved with accrediting personnel, facilities, and entomology kits. Many discrepancies within the reported practices and accreditation processes highlight the need for the adoption of a standard code of practice among forensic entomologists. PMID:24219583

    The emerging field of microbial forensics played a major role in the investigation of the 2001 anthrax mailings and has been closely associated with the process of attribution, or identifying the perpetrator of a biological attack for purposes of criminal prosecution or military retaliation. Nevertheless, microbial forensics has other potential applications in intelligence, nonproliferation, and verification. This article describes the relevance of microbial forensics for a variety of law enforcement and national security missions, examines the obstacles to its broader use, and concludes with some policy recommendations.

    Current distributions of open source forensic software provide digital investigators with a large set of heterogeneous tools. Their use is not always focused on the target and requires high technical expertise. We present a new GNU/Linux live distribution, named CAINE (Computer Aided INvestigative Environment) that contains a collection of tools wrapped up into a user friendly environment. The CAINE forensic framework introduces novel important features, aimed at filling the interoperability gap across different forensic tools. Moreover, it provides a homogeneous graphical interface that drives digital investigators during the acquisition and analysis of electronic evidence, and it offers a semi-automatic mechanism for the creation of the final report.

    Tanner, April; Dampier, David

    Research in digital forensics has yet to focus on modeling case domain information involved in investigations. This paper shows how concept mapping can be used to create an excellent alternative to the popular checklist approach used in digital forensic investigations. Concept mapping offers several benefits, including creating replicable, reusable techniques, simplifying and guiding the investigative process, capturing and reusing specialized forensic knowledge, and supporting training and knowledge management activities. The paper also discusses how concept mapping can be used to integrate case-specific details throughout the investigative process.

    The Kyrgyz government declared a policy of "zero tolerance" for torture and began reforms to stop such practice, a regular occurrence in the country's daily life. This study presents the results of 10 forensic evaluations of individuals alleging torture; they represent 35% of all criminal investigations into torture for the January 2011-July 2012 period. All individuals evaluated were male with an average age of 34 years. Police officers were implicated as perpetrators in all cases. All individuals reported being subjected to threats and blunt force trauma from punches, kicks, and blows with objects such as police batons. The most common conditions documented during the evaluations were traumatic brain injury and chronic seizures. Psychological sequelae included post-traumatic stress disorder and major depressive disorder, which was diagnosed in seven individuals. In all cases, the physical and psychological evidence was highly consistent with individual allegations of abuse. These forensic evaluations, which represent the first ever to be conducted in Kyrgyzstan in accordance with Istanbul Protocol standards, provide critical insight into torture practices in the country. The evaluations indicate a pattern of brutal torture practices and inadequate governmental and nongovernmental forensic evaluations. PMID:25623194

    Despite increasing interest in the measurement of social functioning in people with personality disorder, there are currently no social functioning measures specifically for forensic or other inpatients with a diagnosis of personality disorder. This paper describes the development and validation of the Hospital Social Functioning Questionnaire (HSFQ), a self-report measure of social functioning for forensic inpatients. A sample of fifty four male inpatients in a forensic personality disorder treatment unit completed the HSFQ and a range of measures indicative of social functioning, namely self-report measures of psychological wellbeing and symptoms, recorded incidents of self-harm and aggression. Clinicians' ratings of global functioning, and clinically assessed personality disorder severity were also collected. The HSFQ showed good internal consistency and test-retest reliability, good concurrent validity with self-report measures of personality pathology, other symptoms and psychological wellbeing, but only a moderate correlation with clinician-rated global functioning and with frequency of self-harm and aggressive behavior. These results suggest that the HSFQ is a more focused measure of social functioning than the Global Assessment of Functioning (GAF), which conflates social functioning with self harm and aggressive behavior. The HSFQ is a potentially useful assessment of social functioning in secure and other inpatient settings. PMID:25660210

    Resolution is a key parameter for differentiating among the large number of strain typing methods that could be applied to pathogens involved in bioterror events or biocrimes. In this report we develop a first-principles analysis of strain typing resolution using a simple mathematical model to provide a basis for the rational design of microbial typing systems for forensic applications. We derive two figures of merit that describe the resolving power and phylogenetic depth of a strain typing system. Rough estimates of these figures-of-merit for MLVA, MLST, IS element, AFLP, hybridization microarrays, and other bacterial typing methods are derived from mutation rate data reported in the literature. We also discuss the general problem of how to construct a ''universal'' practical typing system that has the highest possible resolution short of whole-genome sequencing, and that is applicable with minimal modification to a wide range of pathogens.

    Traditionally law enforcement agencies have relied on basic measurement and imaging tools, such as tape measures and cameras, in recording a crime scene. A disadvantage of these methods is that they are slow and cumbersome. The development of a portable system that can rapidly record a crime scene with current camera imaging, 3D geometric surface maps, and contribute quantitative measurements such as accurate relative positioning of crime scene objects, would be an asset to law enforcement agents in collecting and recording significant forensic data. The purpose of this project is to develop a feasible prototype of a fast, accurate, 3D measurement and imaging system that would support law enforcement agents to quickly document and accurately record a crime scene.

    This paper is designed to assist forensic psychiatrists/psychologists who evaluate adults who commit sexual crimes against children on the Internet. The typical offender is an adult male who logs onto the Internet and enters a chat room in which children congregate. Unbeknownst to the offender, undercover police officers are posing as minors in the chat rooms. The undercover officer (pretend kid) and offender engage in increasingly explicit, sexual conversation; the offender may transmit erotic photographs to the undercover officer and/or arrange to meet at a motel in order to have sexual intercourse. The authors will discuss the relevant legal, clinical, and ethical aspects of examining these offenders, and describe specific cases that the author (2) evaluated. PMID:11714151

    2010-01-01

    DNA analysis is frequently used to acquire information from biological material to aid enquiries associated with criminal offences, disaster victim identification and missing persons investigations. As the relevance and value of DNA profiling to forensic investigations has increased, so too has the desire to generate this information from smaller amounts of DNA. Trace DNA samples may be defined as any sample which falls below recommended thresholds at any stage of the analysis, from sample detection through to profile interpretation, and can not be defined by a precise picogram amount. Here we review aspects associated with the collection, DNA extraction, amplification, profiling and interpretation of trace DNA samples. Contamination and transfer issues are also briefly discussed within the context of trace DNA analysis. Whilst several methodological changes have facilitated profiling from trace samples in recent years it is also clear that many opportunities exist for further improvements. PMID:21122102

    Forensic odontology plays a major role in the identification of those individuals who cannot be identified visually or by other means. The unique nature of dental anatomy and placement of custom restorations ensure accuracy when the techniques are correctly employed. It is evident that identification of victims in accidents and natural calamities is of utmost importance and is a challenging task. The teeth may also be used as weapons and under certain circumstances; they may provide information regarding the identity of the biter. Dental professionals play a major role in keeping accurate dental records and providing all necessary information so that legal authorities may recognize malpractices, negligence, fraud child abuse and also, identify an individual. In this article, we will discuss such evolvement of the subject. PMID:25328306

Recorded human history goes back for 6000 years. Sumeria, Babylon and Egypt all contributed to the development of forensic medicine. Imhotep was probably the first real medicolegal expert. Hippocrates, the Greek physician, and Galen, the Roman, made considerable contributions. Little advance was made during the millenium of the Dark Ages. But Renaissance medicine gave this branch of medicine an impetus in the seventeenth, eighteenth and nineteenth centuries, and in the twentieth, interest in forensic medicine is worldwide.

    2010-07-01

    Forensic medicine incorporates research, teaching and professional service. In the routine practice this encompasses interdisciplinary cooperation with physicians, natural scientists and the legal profession. Lectures in forensic medicine include the correct performance of an external examination of corpses, which every physician must be capable of, just as medical questions and the evidential documentation of injuries. Clinical forensic medicine encompasses the examination and documentation of living victims of physical and/or sexual violence. For further training to become a specialist for forensic medicine it is mandatory to undertake a 6-month training period in pathology. Fatalities with an unclear or unnatural manner of death must be registered with the police. On suspicion of third party involvement the public prosecutor will request a legal autopsy, which is carried out and documented by two physicians in accordance with the penal code. Imaging procedures are standard for an autopsy. Extensive samples are taken for additional testing, such as toxicological and molecular biological investigations. PMID:20424845

    Although thousands of search engines and databases are available online, finding answers to specific forensic science questions can be a challenge even to experienced Internet users. Because there is no central repository for forensic science information, and because of the sheer number of disciplines under the forensic science umbrella, forensic scientists are often unable to locate material that is relevant to their needs. The author contends that using six publicly accessible search engines and databases can produce high-quality search results. The six resources are Google, PubMed, Google Scholar, Google Books, WorldCat, and the National Criminal Justice Reference Service. Carefully selected keywords and keyword combinations, designating a keyword phrase so that the search engine will search on the phrase and not individual keywords, and prompting search engines to retrieve PDF files are among the techniques discussed.

    Forensic dentistry has become an integral part of forensic science over the past 100 years that utilizes dental or oro-facial findings to serve the judicial system. This has been due to the dedication of people like Gustafson's, Keiser-Nielson, and Suzuki for this field. They established the essential role which forensic dentistry plays mainly in the identification of human remains. The tooth has been used as weapons and under certain circumstances, may leave information about the identity of the biter. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize mal practice, negligence, fraud or abuse, and identity of unknown individuals. This paper will try to summarize the various roles of dental experts in forensic medicine. PMID:25298709

    The forensic pathologist has always had a central role in the identification of the dead in every day practice, in accidents, and in disasters involving hundreds or thousands of victims. This role has changed in recent years, as advances in forensic odontology, genetics and anthropology have improved the chances of identifying victims beyond recognition. According to the Interpol DVI Guide, fingerprints, dental examination and DNA are the primary identifiers, and this has given new emphasis to the role of the forensic pathologist as the leader of a multidisciplinary team of experts in a disaster situation, based on his or her qualifications and the experience gained from doing the same work in the everyday situation of an institute of forensic medicine.

    Numerous authors have opined that forensic activities have become more prominent within clinical neuropsychology. To investigate the merits of these claims, the entire contents of Archives of Clinical Neuropsychology (ACN), Journal of Clinical and Experimental Neuropsychology (JCEN), and The Clinical Neuropsychologist (TCN) from 1990 through 2000 were reviewed and cataloged. These three journals were selected because they are the highest-ranking clinical subscription journals according to surveys of neuropsychology practitioners. Prior to rating journal content, various categories of interest were delineated and practice ratings were obtained until the two raters reached 92% agreement. Each of the raters read the journal contents and recorded content ratings for half of the journal issues under review. Results of the 8323 ratings demonstrated increases across time in the absolute numbers of articles related to forensic neuropsychology, although variable and different for each journal. Published articles that were partially or substantially forensic in nature in the three journals combined increased from 4% in 1990 to 14% in 2000. An annual peak in absolute number (n=32;16%) of forensic journal articles occurred in 1997. The most common topic of 139 articles published in ACN, JCEN, and TCN from 1990 to 2000 was malingering, which appeared in 86% of the general forensic articles. Forensic presentations at annual NAN meetings ranged from 3.9 to 11.3% (M=8%) of the convention programs, whereas within Division 40's programs at the American Psychological Association meeting, the average percentage ranged from 2.3 to 11.7% (M=6%). Results pertaining to each journal and to specific forensic topics are presented and implications of these and other results are discussed. PMID:12822057

    Forensic age estimation is a scientific process that estimates an individual's true chronologic age by assessing skeletal and dental development and maturation. Although human growth and maturation is unique to each individual, dental techniques for estimating age are currently considered the best in assessing true chronologic age particularly during the age range when the dentition is undergoing morphologic development. This article reviews the principles, methodology and commonly used techniques in forensic age estimation cases. PMID:26126347

  14. Computer Forensics Education - the Open Source Approach

    NASA Astrophysics Data System (ADS)

    Huebner, Ewa; Bem, Derek; Cheung, Hon

    In this chapter we discuss the application of the open source software tools in computer forensics education at tertiary level. We argue that open source tools are more suitable than commercial tools, as they provide the opportunity for students to gain in-depth understanding and appreciation of the computer forensic process as opposed to familiarity with one software product, however complex and multi-functional. With the access to all source programs the students become more than just the consumers of the tools as future forensic investigators. They can also examine the code, understand the relationship between the binary images and relevant data structures, and in the process gain necessary background to become the future creators of new and improved forensic software tools. As a case study we present an advanced subject, Computer Forensics Workshop, which we designed for the Bachelor's degree in computer science at the University of Western Sydney. We based all laboratory work and the main take-home project in this subject on open source software tools. We found that without exception more than one suitable tool can be found to cover each topic in the curriculum adequately. We argue that this approach prepares students better for forensic field work, as they gain confidence to use a variety of tools, not just a single product they are familiar with.

    Hibbard, Roberta; Barlow, Jane; Macmillan, Harriet

    2012-08-01

    Psychological or emotional maltreatment of children may be the most challenging and prevalent form of child abuse and neglect. Caregiver behaviors include acts of omission (ignoring need for social interactions) or commission (spurning, terrorizing); may be verbal or nonverbal, active or passive, and with or without intent to harm; and negatively affect the child's cognitive, social, emotional, and/or physical development. Psychological maltreatment has been linked with disorders of attachment, developmental and educational problems, socialization problems, disruptive behavior, and later psychopathology. Although no evidence-based interventions that can prevent psychological maltreatment have been identified to date, it is possible that interventions shown to be effective in reducing overall types of child maltreatment, such as the Nurse Family Partnership, may have a role to play. Furthermore, prevention before occurrence will require both the use of universal interventions aimed at promoting the type of parenting that is now recognized to be necessary for optimal child development, alongside the use of targeted interventions directed at improving parental sensitivity to a child's cues during infancy and later parent-child interactions. Intervention should, first and foremost, focus on a thorough assessment and ensuring the child's safety. Potentially effective treatments include cognitive behavioral parenting programs and other psychotherapeutic interventions. The high prevalence of psychological abuse in advanced Western societies, along with the serious consequences, point to the importance of effective management. Pediatricians should be alert to the occurrence of psychological maltreatment and identify ways to support families who have risk indicators for, or evidence of, this problem. PMID:22848125

    2006-01-27

    The debate in forensic science concentrates on issues such as standardisation, accreditation and de-contextualisation, in a legal and economical context, in order to ensure the scientific objectivity and efficiency that must guide the process of collecting, analysing, interpreting and reporting forensic evidence. At the same time, it is recognised that forensic case data is still poorly integrated into the investigation and the crime analysis process, despite evidence of its great potential in various situations and studies. A change of attitude is needed in order to accept an extended role for forensic science that goes beyond the production of evidence for the court. To stimulate and guide this development, a long-term intensive modelling activity of the investigative and crime analysis process that crosses the boundaries of different disciplines has been initiated. A framework that fully integrates forensic case data shows through examples the capital accumulated that may be put to use systematically. PMID:16099615

    Forensic experts play a major role in the legal process as they offer professional expert opinion and evidence within the criminal justice system adjudicating on the innocence or alleged guilt of an accused person. In this respect, medico-legal examination is an essential part of the investigation process, determining in a scientific way the cause(s) and manner of unexpected and/or unnatural death or bringing clinical evidence in case of physical, psychological, or sexual abuse in living people. From a legal perspective, these types of investigation must meet international standards, i.e., it should be independent, effective, and prompt. Ideally, the investigations should be conducted by board-certified experts in forensic medicine, endowed with a solid experience in this field, without any hierarchical relationship with the prosecuting authorities and having access to appropriate facilities in order to provide forensic reports of high quality. In this respect, there is a need for any private or public national or international authority including non-governmental organizations seeking experts qualified in forensic medicine to have at disposal a list of specialists working in accordance with high standards of professional performance within forensic pathology services that have been successfully submitted to an official accreditation/certification process using valid and acceptable criteria. To reach this goal, the National Association of Medical Examiners (NAME) has elaborated an accreditation/certification checklist which should be served as decision-making support to assist inspectors appointed to evaluate applicants. In the same spirit than NAME Accreditation Standards, European Council of Legal Medicine (ECLM) board decided to set up an ad hoc working group with the mission to elaborate an accreditation/certification procedure similar to the NAME's one but taking into account the realities of forensic medicine practices in Europe and restricted to post

    The revulsive publications during the last years on the precariousness of forensic sciences worldwide have promoted the move of major steps towards improvement of this science. One of the steps (viz. a higher involvement of metabolomics in the new era of forensic analysis) deserves to be discussed under different angles. Thus, the characteristics of metabolomics that make it a useful tool in forensic analysis, the aspects in which this omics is so far implicit, but not mentioned in forensic analyses, and how typical forensic parameters such as the post-mortem interval or fingerprints take benefits from metabolomics are critically discussed in this review. The way in which the metabolomics-forensic binomial succeeds when either conventional or less frequent samples are used is highlighted here. Finally, the pillars that should support future developments involving metabolomics and forensic analysis, and the research required for a fruitful in-depth involvement of metabolomics in forensic analysis are critically discussed.

    Close co-operation between forensic scientists, medico-legal doctors, and police forces made it possible to estimate not only the post-mortem interval but also the time since a child was neglected. On the skin surface under the diaper (anal-genital area), third instar larvae of the false stable fly Muscina stabulans FALLEN, and the lesser house fly Fannia canicularis L. were found. F. canicularis adults are attracted to both feces and urine. From the face, larvae of the bluebottle fly Calliphora vomitoria L. were collected. C. vomitoria maggots are typical early inhabitants of corpses. From the developmental times of the flies, it was estimated that the anal-genital area of the child had not been cleaned for about 14 days (7-21 day range), and that death occurred only 6-8 days prior to discovery of the body. This is the first report where an examination of the maggot fauna on a person illustrated neglect that had occurred prior to death. PMID:11457624

    Islam is the second most popular monotheistic religion in the world. Its followers, the Muslims, are about 1.2 billion people and are the majority in 56 countries around the globe. Islam is an holistic way and model of life and its rules, according to a large proportion of Muslims, should have more power than the laws deriving from any secular authority. This means that the divine laws, as depicted from Islam's holy scripts, should be the laws of the land. In the strict Islamic states, as Saudi Arabia, the Islamic law or the Shari'ah prevails. Shari'ah means the path, the road each faithful Muslim should follow according to the rules of God. The Islamic views on mental health have some interesting characteristics: on the one hand, the moral necessity for the protection and care of the vulnerable individuals is very strong, but on the other hand superstitions and stigmatization influence the peoples' attitude against mental health patients. At the beginning of its historical course, Islamic world was a pioneer concerning mental health care. Unfortunately, as time passed by, we have observed considerable regression. In our days mental health services provided in most of the Islamic states cannot be considered adequate according to modern Western standards. The same course characterizes the Forensic Psychiatric services and the relevant legislation in the Islamic world. PMID:25630549

    Infanticides are not specifically classified in German criminal records. Thus, the number of infanticides varies depending on different sources of information. Reports from expert witnesses (n=48, 1980-2007) from the German regions around Munich and Rostock were analyzed retrospectively in order to identify sociodemographic, clinical and forensic characteristics of child murders. In 87.5% of the cases the victims were the natural children of which 25 were younger than 1 year old. Female offenders outnumbered male offenders by 3:1 and on average females were 8 years younger than males (26.5 years for females and 34.2 years for males). The motives included unwanted pregnancy/child, altruistic deeds, acute psychoses, child abuse (sexual abuse, neglect or negligence), drug or alcohol abuse, sadistic punishment of the child and revenge on partners. In 27 cases a restricted or exemption from criminal responsibility was acknowledged. About one third of the offenders consulted a physician before the crime. For an improvement in primary prevention, support networks should be integrated and sensitized to the problem. PMID:20617427

    Discussions of nuclear forensics are often restricted to work performed by radio-chemists measuring nuclear material attributes in the laboratory. However, this represents only one portion of the work required to answer critical questions. Laboratory analysis results in measurements that need to be evaluated. The results of those evaluations must be put into their proper context in order for them to be useful to others and often require merging those results with additional information. This may contribute to attribution, by virtue of inclusion or exclusion. Finally, the end product must be presented such that appropriate actions can be taken. This could include prosecution by law enforcement, policy initiatives on the part of legislative bodies, or military action in the case of nuclear attack (whether that attack is preempted or not). Using the discovery of a sample of plutonium during cleanup activities at Hanford in 2004, we will step through the process of discovery (representing an interdiction), initial field analysis, laboratory analysis, data evaluation and merging with additional data (similar to law enforcement and/or all source), thereby providing an example of an integrated approach.

    The most common role of the forensic dentist is the identification of deceased individuals. Dental identifications have always played a key role in natural and manmade disaster situations, and in particular, the mass casualties normally associated with aviation disasters. Because of the lack of a comprehensive fingerprint database, dental identification continues to be crucial in the world. An all-acrylic resin appliance such as a full denture or an all-acrylic partial denture (or orthodontic appliance), prior to delivery, could be inscribed with the patient's full name on a substrate (paper, metal) and sealed inconspicuously into the surface of a denture by various processes. It has been noted by several authors that in many cases of air disaster where the limbs are completely burnt off, some denture materials survive, especially the posterior part of acrylic dentures and metal-based dentures. Thus, marked dental prostheses (full and partial dentures, mouthguards and removal orthodontic appliances) would lead to rapid identification in the event of accidents and disaster. PMID:23087581

    Mayer, Owen; Stamm, Matthew C.

    2015-03-01

    Over the past decade, a number of information forensic techniques have been developed to identify digital image manipulation and falsification. Recent research has shown, however, that an intelligent forger can use anti-forensic countermeasures to disguise their forgeries. In this paper, an anti-forensic technique is proposed to falsify the lateral chromatic aberration present in a digital image. Lateral chromatic aberration corresponds to the relative contraction or expansion between an image's color channels that occurs due to a lens's inability to focus all wavelengths of light on the same point. Previous work has used localized inconsistencies in an image's chromatic aberration to expose cut-and-paste image forgeries. The anti-forensic technique presented in this paper operates by estimating the expected lateral chromatic aberration at an image location, then removing deviations from this estimate caused by tampering or falsification. Experimental results are presented that demonstrate that our anti-forensic technique can be used to effectively disguise evidence of an image forgery.

    Due to the globalisation of legal (and illegal) trade there is an increasing demand for techniques which can verify the geographical origin and transfer routes of many legal and illegal commodities and products. Although geological techniques have been used in forensic investigations since the emergence of forensics as a science in the late eighteen hundreds, the last decade has seen a marked increase in geo-scientists initiating concept studies using the latest analytical techniques, including studying natural abundance isotope variations, micro analysis with laser ablation ICPMS and geochemical mapping. Most of the concept studies have shown a good potential but uptake by the law enforcement and legal community has been limited due to concerns about the admissibility of the new methods. As an introduction to the UGU2009 session "Forensic Provenancing using Geological and Geochemical Techniques" I will give an overview of the state of the art of forensic geology and the issues that concern the admissibility of geological forensic evidence. I will use examples from the NITECRIME and FIRMS networks, the EU TRACE project and other projects and literature to illustrate the important issues at hand.

    Organ procurement and transplantation have grown steadily, and the need for organs will only rise in the future. Increasing the number of potential donors is therefore paramount. However, transplant coordination teams face refusals that can be linked to the contexts of the deaths, especially when they involve legal issues. In France, deaths involving legal proceedings are not uncommon (7-10%). In these cases, the prosecutor is immediately contacted, and makes the decision of whether to remove the involved organs. Refusals of this type represent 4% (approximately 30 cases per year) of obstacles to organ removals, and are governed by specific legislation. Thus, the prosecutor must arrange contact with a forensic pathologist and with the organ transplant teams to assemble all of the necessary elements for him to take the decision. To assist prosecutors in their decision making and to ensure them scientific rigour, the French Society of Forensic Medicine sought to develop a national recommendation to harmonise practices; it emerged in early 2013. The guideline makes practical recommendations, including among others: nominating local referents; writing regional protocols between judicial authorities, forensic pathologists and transplant teams; establishing terms for the forensic pathologist's intervention on the donor's body before and after a procurement. This recommendation by the French Society of Forensic Medicine aimed to combine two interests: addressing the shortage of organs, and fulfilling the requisites of a criminal investigation by standardising practices and encouraging communication.

    Reilly, Dallas David

    Concerns over the proliferation and instances of nuclear material in the environment have increased interest in the expansion of nuclear forensics analysis and attribution programs. A new related field, molecular forensic science (MFS) has helped meet this expansion by applying common scientific analyses to nuclear forensics scenarios. In this work, MFS was applied to three scenarios related to nuclear forensics analysis. In the first, uranium dioxide was synthesized and aged at four sets of static environmental conditions and studied for changes in chemical speciation. The second highlighted the importance of bulk versus particle characterizations by analyzing a heterogeneous industrially prepared sample with similar techniques. In the third, mixed uranium/plutonium hot particles were collected from the McGuire Air Force Base BOMARC Site and analyzed for chemical speciation and elemental surface composition. This work has identified new signatures and has indicated unexpected chemical behavior under various conditions. These findings have lead to an expansion of basic actinide understanding, proof of MFS as a tool for nuclear forensic science, and new areas for expansion in these fields.

    2010-09-01

    Wildlife DNA forensics is receiving increasing coverage in the popular press and has begun to appear in the scientific literature in relation to several different fields. Recognized as an applied subject, it rests on top of very diverse scientific pillars ranging from biochemistry through to evolutionary genetics, all embedded within the context of modern forensic science. This breadth of scope, combined with typically limited resources, has often left wildlife DNA forensics hanging precariously between human DNA forensics and academics keen to seek novel applications for biological research. How best to bridge this gap is a matter for regular debate among the relatively few full-time practitioners in the field. The decisions involved in establishing forensic genetic services to investigate wildlife crime can be complex, particularly where crimes involve a wide range of species and evidential questions. This paper examines some of the issues relevant to setting up a wildlife DNA forensics laboratory based on experiences of working in this area over the past 7 years. It includes a discussion of various models for operating individual laboratories as well as options for organizing forensic testing at higher national and international levels. PMID:20593251

    Unnatural deaths in women of reproductive age (range 12-49 years) have a serious psychological and social impact on the family and community. Deaths among women of reproductive age reported as medico-legal cases were investigated to see the trend in terms of cause and manner of death. The study group consisted of a series of 328 consecutive forensic autopsies on women in the reproductive age group, performed between 2009 and 2011 at the Government Wenlock District Hospital, Mangalore, India by qualified specialist forensic medicine experts. Unnatural deaths formed 93.6% of the cohort. The top three causes of death included burns, poisoning and hanging forming 69.5% of the cases. The manner of death was suicide in 45.4% cases, accident in 43.6% cases and homicide in 4.6% cases. The circumstances of death were related to alleged medical negligence in 2.4% cases. Death in 4% cases was natural mannered with a disease being the cause of death. Three-fourths of the victims were married. Married women formed 63.1% of the suicidal victims. Homicidal deaths were not reported among unmarried women. The preponderant method of suicide was by poisoning at 42.3% (63 cases), followed by hanging (34.9%), burns (11.4%) and drowning (9.4%). These four methods comprised 98% of the total suicidal deaths in this study cohort. Accidental deaths were predominantly caused by burns (62.2%) and road traffic accident (23.1%). Two-thirds of the homicidal deaths were due to assault caused by blunt-force trauma, ligature strangulation and sharp-force trauma. One-third of the homicidal victims died due to burns. With a clear understanding of the cause and manner of death, it may be possible to predict, and hopefully prevent, future cases of unnatural deaths in women of reproductive age who form a very important group of society.

    Background: Police personnel play an important role in collecting and producing evidence. Knowledge about the various aspects of forensic as well as dental sciences and related evidence in them provide a golden opportunity to forensic odontologists to actively participate in the identification of the accused or victim. They can also act as an expert witness in court to produce forensic dental evidence. Aim: To evaluate the awareness and knowledge about the utilization of forensic odontology during evidence collection by the crime scene investigation (CSI) officers. Materials and Methods: Four hundred police officers were included in this survey. A questionnaire was designed to assess the awareness and knowledge about forensic odontology and application of the known knowledge in identifying and considering the dental evidences. Data were analyzed using the software Statistical Package for Social Sciences (SPSS, Chicago, Il, USA) version 17.0 by comparing the overall awareness of forensic odontology among the trained SI officers and trainee police personnel. Results: The collected results showed that there is a requirement for changes in the current practice of evidence collection and highlighted the need for better communication between the police personnel and forensic odontologists. A significantly higher number of police officers in both the trained and trainee groups reported knowledge about the subject (P < 0.001) through newspapers and mass media as the sources of knowledge. Conclusion: Even though the respondents have knowledge about forensic odontology, there is a lack of communication and facilities in their system; hence, steps must be taken to educate the police personnel about the application of forensic odontology.

Due to the ephemeral crime scene characteristics, these photographs can often capture information that is never to be seen again. This paper presents a novelty approach for the documentation, analysis, and visualization of crime scenes for which only a single perspective image is available. The photogrammetric process consists of a few well-known steps in close-range photogrammetry: features extraction, vanishing points computation, camera self-calibration, 3D metric reconstruction, dimensional analysis, and interactive visualization. Likewise, the method incorporates a quality control of the different steps accomplished sequentially. As a result, several cases of study are presented in the experimental results section in order to test their viability. The full approach can be applied easily through the free software, sv3DVision, which has been evaluated by a number of police officers, forensic scientists, and forensic educators satisfactorily.

    Wojcik, Marika; Venter, Hein; Eloff, Jan; Olivier, Martin

    Digital forensics involves the identification, preservation, analysis and presentation of electronic evidence for use in legal proceedings. In the presence of contradictory evidence, forensic investigators need a means to determine which evidence can be trusted. This is particularly true in a trust model environment where computerised agents may make trust-based decisions that influence interactions within the system. This paper focuses on the analysis of evidence in trust-based environments and the determination of the degree to which evidence can be trusted. The trust model proposed in this work may be implemented in a tool for conducting trust-based forensic investigations. The model takes into account the trust environment and parameters that influence interactions in a computer network being investigated. Also, it allows for crimes to be reenacted to create more substantial evidentiary proof.

  8. A CONCEPT FOR NATIONAL NUCLEAR FORENSIC LIBRARIES

    The interpretation of data from the nuclear forensic analysis of illicit nuclear material of unknown origin requires comparative data from samples of known origin. One way to provide such comparative data is to create a system of national nuclear forensics libraries, in which each participating country stores information about nuclear or other radioactive material that either resides in or was manufactured by that country. Such national libraries could provide an authoritative record of the material located in or produced by a particular country, and thus forms an essential prerequisite for a government to investigate illicit uses of nuclear or other radioactive material within its borders. We describe the concept of the national nuclear forensic library, recommendations for content and structure, and suggested querying methods for utilizing the information for addressing nuclear smuggling.

  9. Forensic psychiatry: contemporary scope, challenges and controversies

    ARBOLEDA-FLÓREZ, JULIO

    2006-01-01

    Forensic psychiatry is the branch of psychiatry that deals with issues arising in the interface between psychiatry and the law, and with the flow of mentally disordered offenders along a continuum of social systems. Modern forensic psychiatry has benefited from four key developments: the evolution in the understanding and appreciation of the relationship between mental illness and criminality; the evolution of the legal tests to define legal insanity; the new methodologies for the treatment of mental conditions providing alternatives to custodial care; and the changes in attitudes and perceptions of mental illness among the public. This paper reviews the current scope of forensic psychiatry and the ethical dilemmas that this subspecialty is facing worldwide. PMID:16946941

    The author's thoughts and opinions on where the field of forensic DNA testing is headed for the next decade are provided in the context of where the field has come over the past 30 years. Similar to the Olympic motto of ‘faster, higher, stronger’, forensic DNA protocols can be expected to become more rapid and sensitive and provide stronger investigative potential. New short tandem repeat (STR) loci have expanded the core set of genetic markers used for human identification in Europe and the USA. Rapid DNA testing is on the verge of enabling new applications. Next-generation sequencing has the potential to provide greater depth of coverage for information on STR alleles. Familial DNA searching has expanded capabilities of DNA databases in parts of the world where it is allowed. Challenges and opportunities that will impact the future of forensic DNA are explored including the need for education and training to improve interpretation of complex DNA profiles. PMID:26101278

    In recent years, saliva has attracted much interest among researchers especially in the field of forensic sciences. This complex body fluid is gaining popularity due to its ease of collection, safety in handling and its close relationship with plasma. Analysis of saliva for serological testing and cellular content has proved to be of wide use in crime detection, drug and alcohol abuse, hormone identification, cases of poisoning and animal bites. There is a need for forensic laboratories to automate the settings specific for saliva as routinely done for blood or urine in order to consider saliva as the primary investigating tool in the absence of other body fluids. This update is aimed at highlighting the many uses of saliva in the practice of forensic odontology. PMID:26604508

    The forensic medical legal evaluation following sexual assault establishes evidence for law enforcement's investigation and criminal prosecution by the legal system. The sexual assault nurse examiner performs the forensic evaluation and uses digital photography to document physical injuries after sexual assault. Photographs have varying degrees of usefulness, but for a photograph to be useful, it must exhibit technical elements for the viewer. There was no tool available to evaluate the usefulness of digital photographs taken during forensic evaluation of genital injuries after sexual assault. The Photo Documentation Image Quality Scoring System (PDIQSS) tool was developed to rate photographic technical elements for usefulness. Using this tool, three experts on two separate occasions evaluated a series of digital photographs taken following sexual assault. The PDIQSS tool predicted usefulness in digital photography of female genital injuries following sexual assault when measured in all dimensions. PMID:21317696

    A biological attack on U.S. crops, rangelands, or forests could reduce yield and quality, erode consumer confidence, affect economic health and the environment, and possibly impact human nutrition and international relations. Preparedness for a crop bioterror event requires a strong national security plan that includes steps for microbial forensics and criminal attribution. However, U.S. crop producers, consultants, and agricultural scientists have traditionally focused primarily on strategies for prevention and management of diseases introduced naturally or unintentionally rather than on responding appropriately to an intentional pathogen introduction. We assess currently available information, technologies, and resources that were developed originally to ensure plant health but also could be utilized for postintroduction plant pathogen forensics. Recommendations for prioritization of efforts and resource expenditures needed to enhance our plant pathogen forensics capabilities are presented. PMID:16760310

    Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results. In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies. The rationale behind using radiocarbon analysis is that aboveground testing of nuclear weapons during the cold war (1955–1963) caused an extreme increase in global levels of carbon-14 (14C), which has been carefully recorded over time. Forty-four teeth from 41 individuals were analyzed using aspartic acid racemization analysis of tooth crown dentin or radiocarbon analysis of enamel, and 10 of these were split and subjected to both radiocarbon and racemization analysis. Combined analysis showed that the two methods correlated well (R2 = 0.66, p < 0.05). Radiocarbon analysis showed an excellent precision with an overall absolute error of 1.0 ± 0.6 years. Aspartic acid racemization also showed a good precision with an overall absolute error of 5.4 ± 4.2 years. Whereas radiocarbon analysis gives an estimated year of birth, racemization analysis indicates the chronological age of the individual at the time of death. We show how these methods in combination can also assist in the estimation of date of death of an unidentified victim. This strategy can be of significant assistance in forensic casework involving dead victim identification. PMID:19965905

    The spread of navigation devices has increased significantly over the last 10 years. With the help of the current development of even smaller navigation receiver units it is to navigate with almost any current smart phone. Modern navigation systems are no longer limited to satellite navigation, but use current techniques, e.g. WLAN localization. Due to the increased use of navigation devices their relevance to forensic investigations has risen rapidly. Because navigation, for example with navigation equipment and smartphones, have become common place these days, also the amount of saved navigation data has risen rapidly. All of these developments lead to a necessary forensic analysis of these devices. However, there are very few current procedures for investigating of navigation devices. Navigation data is forensically interesting because by the position of the devices in most cases the location and the traveled path of the owner can be reconstructed. In this work practices for forensic analysis of navigation devices are developed. Different devices will be analyzed and it is attempted, by means of forensic procedures to restore the traveled path of the mobile device. For analysis of the various devices different software and hardware is used. There will be presented common procedures for securing and testing of mobile devices. Further there will be represented the specials in the investigation of each device. The different classes considered are GPS handhelds, mobile navigation devices and smartphones. It will be attempted, wherever possible, to read all data of the device. The aim is to restore complete histories of the navigation data and to forensically study and analyze these data. This is realized by the usage of current forensic software e.g. TomTology or Oxygen Forensic Suite. It is also attempted to use free software whenever possible. Further alternative methods are used (e.g. rooting) to access locked data of the unit. To limit the practical work the

    The use of a new Magnetic Media Imaging Instrument (MMII) as applied to the forensic investigation of audio tapes is reported. The MMII is an instrument that produces a 2D image of the magnetic fields on a segment of tape up to 5 cm long, with a resolution of about 3 microns. The dynamic range exceeds 40 dB. This allows the visualization of important characteristics such as stop marks with much greater detail than is possible with conventional means such as ferrofluids. Results of tests representing typical forensic examinations are presented.

    The sudden death of a young person is a devastating event for both the family and community. Over the last decade, significant advances have been made in understanding both the clinical and genetic basis of sudden cardiac death. Many of the causes of sudden death are due to genetic heart disorders, which can lead to both structural (eg, hypertrophic cardiomyopathy) and arrhythmogenic abnormalities (eg, familial long QT syndrome, Brugada syndrome). Most commonly, sudden cardiac death can be the first presentation of an underlying heart problem, leaving the family at a loss as to why an otherwise healthy young person has died. Not only is this a tragic event for those involved, but it also presents a great challenge to the forensic pathologist involved in the management of the surviving family members. Evaluation of families requires a multidisciplinary approach, which should include cardiologists, a clinical geneticist, a genetic counselor, and the forensic pathologist directly involved in the sudden death case. This multifaceted cardiac genetic service is crucial in the evaluation and management of the clinical, genetic, psychological, and social complexities observed in families in which there has been a young sudden cardiac death. The present study will address the spectrum of structural substrates of cardiac sudden death with particular emphasis given to the possible role of forensic molecular biology techniques in identifying subtle or even merely functional disorders accounting for electrical instability.

  1. Distinguishing between forensic science and forensic pseudoscience: testing of validity and reliability, and approaches to forensic voice comparison.

    PubMed

    Morrison, Geoffrey Stewart

    2014-05-01

    In this paper it is argued that one should not attempt to directly assess whether a forensic analysis technique is scientifically acceptable. Rather one should first specify what one considers to be appropriate principles governing acceptable practice, then consider any particular approach in light of those principles. This paper focuses on one principle: the validity and reliability of an approach should be empirically tested under conditions reflecting those of the case under investigation using test data drawn from the relevant population. Versions of this principle have been key elements in several reports on forensic science, including forensic voice comparison, published over the last four-and-a-half decades. The aural-spectrographic approach to forensic voice comparison (also known as "voiceprint" or "voicegram" examination) and the currently widely practiced auditory-acoustic-phonetic approach are considered in light of this principle (these two approaches do not appear to be mutually exclusive). Approaches based on data, quantitative measurements, and statistical models are also considered in light of this principle. PMID:24796954

    Forensic psychiatry has evolved into a recognized specialty. Two core competencies, often overlooked but commonplace in forensic psychiatry, are the constructing of forensic reports and the presenting of oral testimony. This article concerns the written forensic report and conceptualizes it as performative writing. We first review the development of the forensic report's structure over the past 30 years or so and then apply constructs from other disciplines as we propose a process for creating narrative forensic reports. Such writing is grounded in the discipline of psychiatry, relies on ethics-based principles of respect for persons and truth-telling, and uses language to tell a story that persuades the legal audience. We examine the impact of voice, pitfalls to avoid, and the concepts of witnessing and labeling, as we describe the process of formulating the narrative through the voice of the forensic expert.

    As an important component of judicial expertise, forensic science is broad and highly specialized. With development of network technology, increasement of information resources, and improvement of people's legal consciousness, forensic scientists encounter many new problems, and have been required to meet higher evidentiary standards in litigation. In view of this, evidence-based concept should be established in forensic medicine. We should find the most suitable method in forensic science field and other related area to solve specific problems in the evidence-based mode. Evidence-based practice can solve the problems in legal medical field, and it will play a great role in promoting the progress and development of forensic science. This article reviews the basic theory of evidence-based medicine and its effect, way, method, and evaluation in the forensic medicine in order to discuss the application value of forensic evidence-based medicine in computer communication networks.

    The rise of forensic pathology in human medicine has greatly contributed to the administration of justice, public safety and security, and medical knowledge. However, the evolution of human forensic pathology has been challenging. Veterinary forensic pathologists can learn from some of the lessons that have informed the growth and development of human forensic pathology. Three main observations have emerged in the past decade. First, wrongful convictions tell us to use a truth-seeking stance rather than an a priori "think dirty" stance when investigating obscure death. Second, missed homicides and concealed homicides tell us that training and certification are the beginning of reliable forensic pathology. Third, failure of a sustainable institutional arrangement that fosters a combination of service, research, and teaching will lead to stagnation of knowledge. Forensic pathology of humans and animals will flourish, help protect society, and support justice if we embrace a modern biomedical scientific model for our practice. We must build training programs, contribute to the published literature, and forge strong collaborative institutions. PMID:27281015

    A number of initiatives are underway in the United States in response to the 2009 critique of forensic science by a National Academy of Sciences committee. This article provides a broad review of activities including efforts of the White House National Science and Technology Council Subcommittee on Forensic Science and a partnership between the Department of Justice (DOJ) and the National Institute of Standards and Technology (NIST) to create the National Commission on Forensic Science and the Organization of Scientific Area Committees. These initiatives are seeking to improve policies and practices of forensic science. Efforts to fund research activities and aid technology transition and training in forensic science are also covered. The second portion of the article reviews standards in place or in development around the world for forensic DNA. Documentary standards are used to help define written procedures to perform testing. Physical standards serve as reference materials for calibration and traceability purposes when testing is performed. Both documentary and physical standards enable reliable data comparison, and standard data formats and common markers or testing regions are crucial for effective data sharing. Core DNA markers provide a common framework and currency for constructing DNA databases with compatible data. Recent developments in expanding core DNA markers in Europe and the United States are discussed. PMID:26164236

    PubMed

    Branigan, Steven

    2013-05-01

    Disk imaging involves copying all of the data from a source disk drive to a target. Typically, the target for the copy is another disk drive. Forensic processes developed years ago do not appear to be adequate for current storage technology. For example, with disk drive capacities now exceeding 1 Terabyte, a typical disk imaging can take over 8 hours at typical rates. With disk drive capacities increasing, forensic copying is expected to take even longer. Along with increase in disk capacity, the industry has also seen an increase in data transfer rates. In many cases, forensic imaging is taking longer than necessary. To identify the bottlenecks, an examination of different methods used to transfer data from a source disk was performed. Factors considered were differing disk access technologies. One finding is that the USB disk access technology (version 2.0 and earlier) is a significant bottleneck for data transfer rates, especially when the USB device is a write-blocker. Other factors that contribute to the efficiency of a forensic copy are the file system used to write a forensic image and the data transfer size used when reading from a disk drive. Optimal parameters for performing a forensic acquisition from a disk drive are identified. PMID:23458238

    In many economically struggling societies, forensic psychiatry is still in its initial developmental stages and thus forensic patients pose an ongoing challenge for the healthcare and juridical systems. In this article, we present the various issues and problems that arose when establishing the first forensic psychiatric institute in Kosovo – a country whose population has constantly been reported as suffering from a high psychiatric morbidity due to long-lasting traumatic experiences during the war of 1999. The implementation of a new forensic psychiatric institute in the developing mental healthcare system of Kosovo, still characterized by considerable shortages, required substantial effort on various levels. On the policy and financial level, it was made possible by a clear intent and coordinated commitment of all responsible national stakeholders and authorities, such as the Ministries of Health and Justice, and by the financial contribution of the European Commission. Most decisive in terms of the success of the project was capacity building in human resources, i.e., the recruitment and training of motivated staff. Training included essential clinical and theoretical issues as well as clearly defined standard operation procedures, guidelines, and checklists to aid daily routine work and the management of challenging situations.

    The technological capability of mobile devices in particular Smartphones makes their use of value to the criminal community as a data terminal in the facilitation of organised crime or terrorism. The effective targeting of these devices from criminal and security intelligence perspectives and subsequent detailed forensic examination of the targeted device will significantly enhance the evidence available to the law enforcement community. When phone devices are involved in crimes, forensic examiners require tools that allow the proper retrieval and prompt examination of information present on these devices. Smartphones that are compliant to Global System for Mobile Communication (GSM) standards, will maintains their identity and user's personal information on Subscriber Identity Module (SIM). Beside SIM cards, substantial amount of information is stored on device's internal memory and external memory modules. The aim of this paper is to give an overview of the currently available forensic software tools that are developed to carry out forensic investigation of mobile devices and point to current weaknesses within this process.

    2011-09-01

    Recent studies and a review in the United States have identified that tens of thousands of used but untested sexual assault examination kits containing medical examination specimens are to be found in police station evidence rooms, forensic science laboratories, hospitals and rape crisis centres. A 2007 survey undertaken by the National Institute of Justice in the United States explored some of the reasons why forensic specimens are not tested by forensic science laboratories. Many of these relate to lack of knowledge on the part of investigators as to how scientific information can assist the investigation process, even if not used subsequently at trial. Cost factors and laboratory casework overload were also identified as significant. For the medical practitioner, the lack of testing poses issues that include quality management of the forensic medical examination and informed consent in a setting requiring the balancing of public and private benefits for the examinee. Limiting scientific testing, even with intelligence-led triaging of sample testing, could have an adverse effect on both prosecution and defence decision-making and ultimately could adversely affect trial outcomes.

    Forensic facial identification examiners are required to match the identity of faces in images that vary substantially, owing to changes in viewing conditions and in a person's appearance. These identifications affect the course and outcome of criminal investigations and convictions. Despite calls for research on sources of human error in forensic examination, existing scientific knowledge of face matching accuracy is based, almost exclusively, on people without formal training. Here, we administered three challenging face matching tests to a group of forensic examiners with many years' experience of comparing face images for law enforcement and government agencies. Examiners outperformed untrained participants and computer algorithms, thereby providing the first evidence that these examiners are experts at this task. Notably, computationally fusing responses of multiple experts produced near-perfect performance. Results also revealed qualitative differences between expert and non-expert performance. First, examiners' superiority was greatest at longer exposure durations, suggestive of more entailed comparison in forensic examiners. Second, experts were less impaired by image inversion than non-expert students, contrasting with face memory studies that show larger face inversion effects in high performers. We conclude that expertise in matching identity across unfamiliar face images is supported by processes that differ qualitatively from those supporting memory for individual faces. PMID:26336174

    2009-08-01

    This review highlights and critically assesses forensic applications in the developing field of ambient ionization mass spectrometry. Ambient ionization methods permit the ionization of samples outside the mass spectrometer in the ordinary atmosphere, with minimal sample preparation. Several ambient ionization methods have been created since 2004 and they utilize different mechanisms to create ions for mass-spectrometric analysis. Forensic applications of these techniques--to the analysis of toxic industrial compounds, chemical warfare agents, illicit drugs and formulations, explosives, foodstuff, inks, fingerprints, and skin--are reviewed. The minimal sample pretreatment needed is illustrated with examples of analysis from complex matrices (e.g., food) on various substrates (e.g., paper). The low limits of detection achieved by most of the ambient ionization methods for compounds of forensic interest readily offer qualitative confirmation of chemical identity; in some cases quantitative data are also available. The forensic applications of ambient ionization methods are a growing research field and there are still many types of applications which remain to be explored, particularly those involving on-site analysis. Aspects of ambient ionization currently undergoing rapid development include molecular imaging and increased detection specificity through simultaneous chemical reaction and ionization by addition of appropriate chemical reagents.

  3. Cult membership as a source of self-cohesion: forensic implications.

    1995-01-01

    The study of cults and the types of individuals drawn to them has long been of interest to psychiatrists. Although many studies have been done on personality types and psychopathology in cult members, no consensus has emerged. Studies of psychopathology in cult members have viewed these individuals as having either no significant impairment, displaying elements of character pathology, or being severely impaired. The result is that no clear theoretical framework has been developed to explain cult membership. Psychoanalytic self psychology, as developed by Heinz Kohut, can provide such a framework. The cult may be understood as serving a number of functions for its members, all of which are designed to restore self-cohesion. Such a formulation implies a degree of self, or narcissistic, pathology in many cult members. This article reviews the literature on cults, offers a self psychology formulation to explain the function that cult membership serves for narcissistically vulnerable personalities, and describes forensic applications of these principles.

  4. Bridging the gap: from biometrics to forensics.

    Biometric recognition, or simply biometrics, refers to automated recognition of individuals based on their behavioural and biological characteristics. The success of fingerprints in forensic science and law enforcement applications, coupled with growing concerns related to border control, financial fraud and cyber security, has generated a huge interest in using fingerprints, as well as other biological traits, for automated person recognition. It is, therefore, not surprising to see biometrics permeating various segments of our society. Applications include smartphone security, mobile payment, border crossing, national civil registry and access to restricted facilities. Despite these successful deployments in various fields, there are several existing challenges and new opportunities for person recognition using biometrics. In particular, when biometric data is acquired in an unconstrained environment or if the subject is uncooperative, the quality of the ensuing biometric data may not be amenable for automated person recognition. This is particularly true in crime-scene investigations, where the biological evidence gleaned from a scene may be of poor quality. In this article, we first discuss how biometrics evolved from forensic science and how its focus is shifting back to its origin in order to address some challenging problems. Next, we enumerate the similarities and differences between biometrics and forensics. We then present some applications where the principles of biometrics are being successfully leveraged into forensics in order to solve critical problems in the law enforcement domain. Finally, we discuss new collaborative opportunities for researchers in biometrics and forensics, in order to address hitherto unsolved problems that can benefit society at large. PMID:26101280

    For a correct classification of dysphagia, morphologic instrumental investigations capable of analysing the anatomical structures of the digestive tract, are undoubtedly essential, but the most important investigations are the functional investigations, such as videofluoroscopy, fiberoptic endoscopic evaluation of swallowing, oro-pharyngo-oesophageal scintigraphy, manometry and pH-metry. Results of these examinations enable us to identify, in patients with dysphagia, the extent of permanent damage, as a consequence of injury to the structures designated to swallowing, must be such that it at least minimally impairs and decreases the relative function, but to a degree that can be detected and, in some manner, measured. From a legal point of view, alterations in swallowing, caused by damage to structures belonging to the respiratory-digestive tract, can be found in crimes against persons and particularly in those involving body injury. In the case of civil, but also in private or social insurance proceedings, it is necessary to distinguish which parameters are to be used as reference for evaluating and quantifying the injury in terms of reimbursement. With the introduction of complete biological well-being, injury is considered as an impairment of the worth and right to enjoy psychological-physical integrity as a quality of life. The criteria currently used internationally take into account the conception of psychological-physical efficiency; nevertheless, in Italian forensic medicine, there is no table that offers a thorough quantification of swallowing modifications, if one excludes oesophageal disorders. Herewith, an evaluation table, dividing oro-pharyngo-oesophageal dysphagia into five, progressively serious classes, is proposed. PMID:17883190

  8. Polycultural psychology.

    PubMed

    Morris, Michael W; Chiu, Chi-yue; Liu, Zhi

    2015-01-01

    We review limitations of the traditional paradigm for cultural research and propose an alternative framework, polyculturalism. Polyculturalism assumes that individuals' relationships to cultures are not categorical but rather are partial and plural; it also assumes that cultural traditions are not independent, sui generis lineages but rather are interacting systems. Individuals take influences from multiple cultures and thereby become conduits through which cultures can affect each other. Past literatures on the influence of multiple cultural identities and cultural knowledge legacies can be better understood within a polyculturalist rubric. Likewise, the concept elucidates how cultures are changed by contact with other cultures, enabling richer psychological theories of intercultural influence. Different scientific paradigms about culture imply different ideologies and policies; polyculturalism's implied policy of interculturalism provides a valuable complement to the traditional policy frames of multiculturalism and colorblindness.

    Over the history of the Savannah River Site, the Savannah River Technology Center (SRTC) has developed high sensitivity analytical capabilities in support of the Site's Environmental Monitoring Program and nuclear material protection process. Many of these techniques are applicable to the developing need for nuclear forensic analysis capabilities. Radiological and critically control procedures are in place at the SRTC, as well as clean room practices, to minimize the potential for a radiological evidentiary sample to contaminate personnel and the facility, as well as to minimize contaminating the sample thus rendering it useless by law enforcement agencies. Some of the trace analytical techniques available at the SRTC include ultra-low-level gamma and alpha spectrometry, high-sensitivity thermal ionization mass spectrometry, time-of-flight secondary ion mass spectrometry and trace organic analyses. These techniques have been tested during a planned domestic smuggling exercise and in the analysis of an unknown sample.In the event of an interdiction involving the illegal use or movement of radioactive material by U.S. law enforcement agencies (local, state or federal) forensic analyses will be used in developing and building a legal case against the perpetrators. The Savannah River Technology Center (SRTC) at the U.S. Department of Energy's Savannah River Site, a former nuclear production site currently conducting nuclear material stabilization missions, located in Aiken South Carolina, has a long history of performing trace analytical analyses for environmental monitoring. Many of these techniques are also applicable to nuclear forensic analyses. A summary of the trace analytical techniques used at the SRTC, which are applicable to Nuclear Forensics, is presented in this paper.Contamination control, of facilities and personnel involved in the analytical analyses, as well as preventing contamination of the sample, is a unique challenge for nuclear forensic analyses

    The human element plays a critical role in forensic science. It is not limited only to issues relating to forensic decision-making, such as bias, but also relates to most aspects of forensic work (some of which even take place before a crime is ever committed or long after the verification of the forensic conclusion). In this paper, I explicate many aspects of forensic work that involve the human element and therefore show the relevance (and potential contribution) of cognitive neuroscience to forensic science. The 10 aspects covered in this paper are proactive forensic science, selection during recruitment, training, crime scene investigation, forensic decision-making, verification and conflict resolution, reporting, the role of the forensic examiner, presentation in court and judicial decisions. As the forensic community is taking on the challenges introduced by the realization that the human element is critical for forensic work, new opportunities emerge that allow for considerable improvement and enhancement of the forensic science endeavour.

    In this paper, we propose an adversary model to facilitate forensic investigations of mobile devices (e.g. Android, iOS and Windows smartphones) that can be readily adapted to the latest mobile device technologies. This is essential given the ongoing and rapidly changing nature of mobile device technologies. An integral principle and significant constraint upon forensic practitioners is that of forensic soundness. Our adversary model specifically considers and integrates the constraints of forensic soundness on the adversary, in our case, a forensic practitioner. One construction of the adversary model is an evidence collection and analysis methodology for Android devices. Using the methodology with six popular cloud apps, we were successful in extracting various information of forensic interest in both the external and internal storage of the mobile device.

    Logs record the events that have happened within in a system so they are considered the history of system activities. They are one of the objects that digital forensic investigators would like to examine when a security incident happens. However, logs were initially created for trouble shooting, and are not purposefully designed for digital forensics. Thus, enormous and redundant log data make analysis tasks complicated and time-consuming to find valuable information, and make logging-related techniques difficult utilized in some systems such as embedded systems. In this paper, we reconsider a data logging mechanism in terms of forensics and consequently, we propose purpose-based forensic logging. In purpose-based forensic logging, we only collect the required logs according to a specific purpose, which could decrease the space that logs occupy and may mitigate the analysis tasks during forensic investigations.

    A fundamental issue that forensic psychiatric nurses struggle with is respect for patient autonomy, as the two liberal prerequisites for autonomy, liberty and rationality, are either absent or compromised in forensic psychiatric settings. In this paper, a contemporary feminist perspective of autonomy, relational autonomy, will be advanced as an alternative approach to the traditional liberalist, Kantian, perspective of autonomy. The concepts of autonomy, paternalism, and justice will be discussed in relation to forensic psychiatric nursing. PMID:17073051

    Medico-legal tasks are not exclusive to forensic medical experts -any physician may face medico-legal issues in his career. Hence, the practice of medicine requires education in legal issues. In Saudi Arabia, there are 30 universities with medical colleges, but we do not know how they teach undergraduate forensic medicine and medico-legal issues. The aim of this study was to discover undergraduate training courses in forensic medicine in Saudi universities. We conducted a cross-sectional study involving all colleges of medicine in Saudi Arabia. A structured, self-administered questionnaire containing 13 items relating to the undergraduate forensic medicine course was distributed. Out of a total of 30 universities, 27 universities responded. Of these 27 universities, 16 (59.26%) teach forensic medicine to undergraduate medical students, and 11 (40.74%) do not teach forensic medicine in their undergraduate curriculum. Of the 27 universities that responded, none has a department of forensic medicine. Eleven universities that do not teach forensic medicine have no forensic medicine unit/division or faculty at all. Forensic medicine belongs to the pathology department in 11 universities, while it belongs to different departments in five universities. There is variation in teaching methods, years where the course is taught and length of the course. Practical and morgue visits take place in 7/16 (43.8%) universities, while 9/16 (56.3%) universities only teach the theoretical aspects of forensic medicine. All 16 universities teach forensic medicine only to medical students and do not teach it to students in other colleges such as dentistry and nursing. PMID:27354384

    2015-07-01

    This article presents an experimental analysis of the combination of different regions of the human face on various forensic scenarios to generate scientific knowledge useful for the forensic experts. Three scenarios of interest at different distances are considered comparing mugshot and CCTV face images using MORPH and SC face databases. One of the main findings is that inner facial regions combine better in mugshot and close CCTV scenarios and outer facial regions combine better in far CCTV scenarios. This means, that depending of the acquisition distance, the discriminative power of the facial regions change, having in some cases better performance than the full face. This effect can be exploited by considering the fusion of facial regions which results in a very significant improvement of the discriminative performance compared to just using the full face.

  20. Bacterial Population Genetics in a Forensic Context

    2009-11-02

    This report addresses the recent Department of Homeland Security (DHS) call for a Phase I study to (1) assess gaps in the forensically relevant knowledge about the population genetics of eight bacterial agents of concern, (2) formulate a technical roadmap to address those gaps, and (3) identify new bioinformatics tools that would be necessary to analyze and interpret population genetic data in a forensic context. The eight organisms that were studied are B. anthracis, Y. pestis, F. tularensis, Brucella spp., E. coli O157/H7, Burkholderia mallei, Burkholderia pseudomallei, and C. botulinum. Our study focused on the use of bacterial population genetics by forensic investigators to test hypotheses about the possible provenance of an agent that was used in a crime or act of terrorism. Just as human population genetics underpins the calculations of match probabilities for human DNA evidence, bacterial population genetics determines the level of support that microbial DNA evidence provides for or against certain well-defined hypotheses about the origins of an infecting strain. Our key findings are: (1) Bacterial population genetics is critical for answering certain types of questions in a probabilistic manner, akin (but not identical) to 'match probabilities' in DNA forensics. (2) A basic theoretical framework for calculating likelihood ratios or posterior probabilities for forensic hypotheses based on microbial genetic comparisons has been formulated. This 'inference-on-networks' framework has deep but simple connections to the population genetics of mtDNA and Y-STRs in human DNA forensics. (3) The 'phylogeographic' approach to identifying microbial sources is not an adequate basis for understanding bacterial population genetics in a forensic context, and has limited utility, even for generating 'leads' with respect to strain origin. (4) A collection of genotyped isolates obtained opportunistically from international locations augmented by phylogenetic representations

    We report a case of fatal Hirschsprung's disease (HD) discovered at autopsy. A 20-year-old man collapsed at home. Emergency medical personnel found him in cardiac arrest and all resuscitative efforts failed. He had a past history of chronic constipation since infancy. Forensic autopsy revealed a megacolon full of gas and stools. Microscopic examination showed absence of ganglion cells in a short segment of the rectum and enterocolitis in the left and transverse colon. HD is rarely described in adults. In many cases, patients complained of constipation since infancy but the affection remained misdiagnosed. The relative good tolerance of the disease is usually due to a short aganglionic bowel segment. Enterocolitis is a frequent and severe complication of HD in children but is rarely described in adults. This case suggests the importance of HD diagnosis in childhood in order to avoid fatal complications with forensic consequences. PMID:17018101

In the absence of fingermarks and of material leading to the recovery of DNA, the forensic scientist has to rely upon chemical analysis of trace amounts of materials including explosives, drugs, toxicological specimens, firearms discharge residues, fibres, glass, paint, soil etc., in order to establish or eliminate links between suspect and victim and/or scene.

    Current content protection systems rely primarily on applied cryptographic techniques but there is an increased use of forensic solutions in images, music and video distribution alike. The two approaches differ significantly, both in terms of technology and in terms of strategy, and thus it begs the question: will one approach take over in the long run, and if so which one? Discussing the evolution of both cryptographic and forensic solutions, we conclude that neither approach is ideal for all constituents, and that in the video space at least they will continue to co-exist for the foreseeable future - even if this may not be the case for other media types. We also analyze shortcomings of these approaches, and suggest that new solutions are necessary in this still emerging marketplace.

    The study presented here is based on 176 forensic dental reports compiled between 1993 and 2001. The bulk of the research took place in 1997, when major construction at Potsdamer Platz and Lehrter Bahnhof in central Berlin required the excavation of considerable quantities of earth. As building proceeded here, at 'Europe's biggest construction site', it revealed not only a large number of long bones, but also a great many skulls and skull fragments. In five instances, complete skeletons were unearthed. Many of the bones ultimately proved to be of animal origin. The police were not instructed to open a single criminal investigation. Identifying and piecing together the material in this context makes tremendous demands of forensic osteology. Establishing the nature of these finds beyond reasonable doubt, and putting a name and date to them, calls for interdisciplinary co-operation between experts in odontology, anthropology, anatomy, radiology and veterinary medicine, not to mention historians.

    Suicidal gunshot wounds are a common appearance in forensic casework. The main task of the coroner lies in the detection of typical pathomorphological correlates, thus differentiating between homicide, suicide and accident. Apart from characteristic bloodstain patterns on the gun and shooting hand, the localisation of the entrance wound and the position of the weapon, additional details such as family background or medical history are important aspects of forensic investigation. An uncommon choice of weaponry and its unusual morphological manifestation often complicate the examination and reconstruction of such cases. Furthermore, due to social stigmatisation, the possibility of secondary changes by relatives at the crime scene should be considered. In addition to autopsy findings, a careful crime scene investigation and bloodstain pattern analysis, a ballistic reconstruction can be an essential tool to gain knowledge of the shooting distance and position of the gun.

    Present literature states that people with acquired organic brain dysfunctions face problems with attention, executive functions and social interaction. During the past years an increasing number of patients with organic brain disorders have been committed into our forensic psychiatry. In current literature studies on this group of patients are underrepresented. This study wanted to verify the impairment of cognitive functions of this specific group of patients. Included were all patients of the forensic psychiatry in Rostock (Mecklenburg-Western-Pomerania) with a primary or secondary organic brain dysfunction who have been committed into the clinic since 2009. These patients went through an extensive neuropsychological test battery. It was found that patients affected by organic brain dysfunction achieve lower results in the neuropsychological testing than non impaired patients, but their results are not as below average than it would have been expected. Further studies should show, if these patients are able to improve their performance while successfully undergoing psychotherapy. PMID:21905991

    Respect for persons is one of forensic psychiatry's ethical principles. It is a principle that is usually laid down without conditions, raising the question of what aspect of someone's "personhood" might deserve our unconditional respect. This paper nominates dignity. One argument against respect for dignity as a principle is that anything it stands for can be subsumed into respecting people's autonomy. This seems not to be correct. Another argument has been that the term dignity has too often been used loosely and vaguely. This does not mean that the term itself is necesarily without value. Dignity seems to refer to something close to the moral meaning of "worth". Respecting dignity has a role in protecting the vulnerable. Respecting a client's dignity is an important aspect of the ethical practice of forensic psychiatry. PMID:25888501

    The elemental analysis of human bones can give information about the dietary habits of the deceased, especially in the last years of their lives, which can be useful for forensic studies. The most important requirement that must be satisfied for this kind of analysis is that the concentrations of analyzed elements are the same as ante mortem. In this work, a set of bones was analyzed using Laser-Induced Breakdown Spectroscopy (LIBS) and validated using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), in order to compare those two techniques and to investigate the effect of possible alterations in the elemental concentrations' proportion resulting from the treatment usually applied for preparing the bones for traditional forensic analysis. The possibility that elemental concentrations' changes would occur after accidental or intentional burning of the bones was also studied.

    Paternal incest is one of the most serious forms of intrafamilial sexual abuse with clinical, social, and legal relevance. A retrospective study was performed, based on forensic reports and judicial decisions of alleged cases of biological paternal incest of victims under 18 years old (n = 215) from 2003 to 2008. Results highlight that in a relevant number of cases: victims were female; the abuse begun at an early age with reiteration; the alleged perpetrator presented a history of sexual crimes against children; sexual practices were physically poorly intrusive, which associated with a forensic medical evaluation performed more than 72 h after the abuse, explain partially the absence of physical injuries or other evidence-these last aspects are different from extrafamilial cases. In conclusion, observations about paternal incest are likely to exacerbate the psychosocial consequences of the abuse and may explain the difficulty and delay in detect and disclose these cases. Few cases were legally prosecuted and convicted. PMID:24180349

    Criminalistics, one of the many sub-divisions of forensic science, is an applied science in which items of evidence are analyzed to provide investigative information and scientific evidence to be used in courts of law. Laboratories associated with governmental public agencies are typically involved in criminal cases as opposed to civil cases, and those types of cases that fall within the jurisdiction of the particular agency. Common analytical divisions within criminalistics laboratories include blood alcohol testing, toxicology, narcotics, questioned documents, biology, firearms, latent fingerprints, physical and trace evidence sections. Specialized field investigative services may be provided in the areas of clandestine drug laboratories and major crimes (firearms, biology, trace, arson/explosives). Forensic science best practice requires the use of non-destructive testing whenever reasonably possible. Several technically difficult situations (bodies and evidence encased in cement and metal) are presented as a challenge to audience.

  11. Is liability possible for forensic psychiatrists?

    PubMed

    Weinstock, R; Garrick, T

    1995-01-01

    Forensic psychiatrists are not as vulnerable to liability as general psychiatrists. The absence of a traditional physician-patient relationship and judicial and quasijudicial immunity are all protective against malpractice actions. Although the absence of a doctor-patient relationship removes an essential element of malpractice, other types of liability such as defamation and ordinary negligence are possible and may not be covered by malpractice insurance. A model is proposed for forensic psychiatry of a partial secondary doctor-patient relationship out-weighted in most circumstances by duties to truth and/or the hiring attorney. Such a model seems most consistent with conflicting duties currently forced on all psychiatrists. This model has advantages of a duty, a violation of which is likely to be covered by malpractice insurance. Rather than deemphasizing partial secondary physician-patient responsibilities, it is advised to stress the important protection provided by judicial and quasijudicial immunity. PMID:8605402

  12. An IP Traceback Model for Network Forensics

    NASA Astrophysics Data System (ADS)

    Pilli, Emmanuel S.; Joshi, R. C.; Niyogi, Rajdeep

    Network forensics deals with capture, recording, analysis and investigation of network traffic to traceback the attackers. Its ultimate goal is to provide sufficient evidence to allow the perpetrator to be prosecuted. IP traceback is an important aspect in the investigation process where the real attacker is identified by tracking source address of the attack packets. In this paper we classify the various approaches to network forensics to list the requirements of the traceback. We propose a novel model for traceback based on autonomous systems (AS) and deterministic packet marking (DPM) to enable traceback even with a single packet. The model is analyzed against various evaluation metrics. The traceback solution will be a major step in the direction of attack attribution and investigation.

    As part of a special issue of The Journal of Head Trauma Rehabilitation, forensic neuropsychology is reviewed as it applies to traumatic brain injury (TBI) and other types of acquired brain injury in which clinical neuropsychologists and rehabilitation psychologists may be asked to render professional opinions about the neurobehavioral effects and outcome of a brain injury. The article introduces and overviews the topic focusing on the process of forensic neuropsychological consultation and practice as it applies to patients with TBI or other types of acquired brain injury. The emphasis is on the application of scientist-practitioner standards as they apply to legal questions about the status of a TBI patient and how best that may be achieved. This article introduces each topic area covered in this special edition. PMID:19333063

  14. Blurriness in Live Forensics: An Introduction

    NASA Astrophysics Data System (ADS)

    Savoldi, Antonio; Gubian, Paolo

    The Live Forensics discipline aims at answering basic questions related to a digital crime, which usually involves a computer-based system. The investigation should be carried out with the very goal to establish which processes were running, when they were started and by whom, what specific activities those processes were doing and the state of active network connections. Besides, a set of tools needs to be launched on the running system by altering, as a consequence of the Locard’s exchange principle [2], the system’s memory. All the methodologies for the live forensics field proposed until now have a basic, albeit important, weakness, which is the inability to quantify the perturbation, or blurriness, of the system’s memory of the investigated computer. This is the very last goal of this paper: to provide a set of guidelines which can be effectively used for measuring the uncertainty of the collected volatile memory on a live system being investigated.

    2004-04-22

    Recovery and comparison of toolmarks, footprint impressions, and fractured surfaces connected to a crime scene are of great importance in forensic science. The purpose of this project is to provide statistical tools for the validation of the proposition that particular manufacturing processes produce marks on the work-product (or tool) that are substantially different from tool to tool. The approach to validation involves the collection of digital images of toolmarks produced by various tool manufacturing methods on produced work-products and the development of statistical methods for data reduction and analysis of the images. The developed statistical methods provide a means to objectively calculate a ''degree of association'' between matches of similarly produced toolmarks. The basis for statistical method development relies on ''discriminating criteria'' that examiners use to identify features and spatial relationships in their analysis of forensic samples. The developed data reduction algorithms utilize the same rules used by examiners for classification and association of toolmarks.

    Objective: The aim of this study was to assess the risk factors and preventive measures for gossypibomas and their medico-legal implications in forensic medicine in the Turkish legal system. Material and Methods: This study involved a retrospective analysis of the records of 39 patients with gossypiboma. Records were available from the Istanbul Forensic Medicine Institution and were surveyed for faulty treatment between 2008 and 2012. Parameters such as distribution of the cases according to specializations, elective and emergency procedures, surgical procedures, radio-opaque sponge and fluoroscopy availability, routine sponge and instrument counting, number of nurses for counting, and control of the operative field by a second surgeon were investigated. Results: All cases were evaluated by the Istanbul Forensic Medicine Institute 3rd Expertise Committee. This committee comprised of specialists from the departments of forensic medicine, orthopedics and traumatology, general surgery, neurology, internal medicine, pediatrics, chest disease, and infectious diseases. All cases were considered as poor medical practice (malpractice) and surgeons were found to be responsible. In 16 of these 39 cases (41%) emergency procedures were performed. No unexpected event was reported in any procedure. In 16 cases (41%), sponge count was performed and was reported to be complete. Operation notes were available in 16 (41%) cases. Control of the operative field was performed by 1 surgeon, and sponge and instrument count was performed by 1 scrub nurse. Radio-opaque sponge and fluoroscopy were available in 9 (23%) centers in these cases. Conclusion: Gossypiboma can be prevented not only with surgeons’ care but also with adequate support of medical device and material. However, it is considered as a poor medical practice. Presence of only 1 general surgeon in the expertise committee and ignorance of the working conditions by the surgeons should be questioned. PMID:26170754

    Human teeth are biological structures that resist extreme conditions thus becoming a useful source of DNA for human forensic identification purposes. When it is possible, forensic prefer only non-damaged teeth whereas those with cavities are usually rejected to avoid both external and internal bacterial contamination. Cavities are one of the most prevalent dental pathology and its incidence increases with ageing. The aim of this study was to validate the use of teeth with cavities for forensic identification. A total of 120 individual teeth from unrelated patients (60 healthy and 60 with cavities, respectively) extracted by a dentist as part of the normal process of treatment, were submitted for further analysis. Dental pulp was obtained after tooth fragmentation, complete DNA was extracted and the corresponding human identification profile was obtained by the AmpFlSTR® NGM SElect™ kit. Cariogenic microbiota was determined by PCR-DGGE with bacterial universal primers and bands were excised, re-amplified and sequenced. From the 120 dental pieces analyzed, a defined genetic profile was obtained in 81 (67.5%) of them, with no statistical differences between the healthy and the cavities-affected teeth. Statistical association between teeth status, DNA content and genetic profiles was not observed. Complex bacterial communities were only detected in the cavities group, being the Streptococcus/Enterococcus, and Lactobacillus genera the most represented. We conclude that teeth with cavities are as valid as healthy dental pieces for forensic human identification. Moreover, the severity of the cariogenic lesion as well as associated bacterial communities seems not to influence the establishment of human dental profiles. PMID:26386340

    Many individual elements comprise a typical forensics process. Collecting evidence, analyzing it, and using results to draw conclusions are all mutually distinct endeavors. Different physical locations and personnel are involved, juxtaposed against an acute need for security and data integrity. Using digital technologies and the Internet's ubiquity, these diverse elements can be conjoined using digital data as the common element. This result is a new data management process that can be applied to serve all elements of the community. The first step is recognition of a forensics lifecycle. Evidence gathering, analysis, storage, and use in legal proceedings are actually just distinct parts of a single end-to-end process, and thus, it is hypothesized that a single data system that can also accommodate each constituent phase using common network and security protocols. This paper introduces the idea of web-based Central Data Repository. Its cornerstone is anywhere, anytime Internet upload, viewing, and report distribution. Archives exist indefinitely after being created, and high-strength security and encryption protect data and ensure subsequent case file additions do not violate chain-of-custody or other handling provisions. Several legal precedents have been established for using digital information in courts of law, and in fact, effective prosecution of cyber crimes absolutely relies on its use. An example is a US Department of Agriculture division's use of digital images to back up its inspection process, with pictures and information retained on secure servers to enforce the Perishable Agricultural Commodities Act. Forensics is a cumulative process. Secure, web-based data management solutions, such as the Central Data Repository postulated here, can support each process step. Logically marrying digital technologies with Internet accessibility should help nurture a thought process to explore alternatives that make forensics data accessible to authorized individuals

    Submission of cases of suspected animal abuse and neglect (AAN) to veterinary pathologists is increasingly frequent. These cases require modification of postmortem procedures and written reports, as the questions asked by courts typically differ from those asked in routine diagnostic cases. Here we review the practice of veterinary forensic pathology as it applies to cases of companion AAN, as well as the fundamental principles of forensic pathology, the components of a forensic necropsy, and the goals of the necropsy in cases of blunt-force trauma, projectile wounds, and starvation. Future directions and endeavors in veterinary forensic pathology are broached. PMID:23686766

    At the beginning of a new millennium it seems a good idea to stop for a moment and take stock of the current state of forensic science. As a field of scientific research and scientific application, forensic science is a little more than a century old. Forensic science may be said to have begun in 1887 with the simultaneous publication of A. Conan Doyle's A Study in Scarlet and Hans Gross's Handbuch f1/4r Untersuchungsrichter. Conan Doyle's novel introduced to the world the character of Sherlock Holmes, whose literary career would popularize the use of physical evidence in criminal investigations. Gross's manual for examining magistrates suggests ways in which the expertise of chemists, biologists, geologists, and other natural scientists could contribute to investigations. Gross's book was translated into a number of languages and went through various updated editions during the course of the century. The intervening century saw the development and application of fingerprinting, firearm and tool mark identification, forensic chemistry, forensic biology, forensic toxicology, forensic odontology, forensic pathology, and forensic engineering. Increasingly, the judicial systems of the industrial nations of the world have come to rely upon the expertise of scientists in a variety of disciplines. In most advanced countries, virtually all criminal prosecutions now involve the presentation of scientific testimony. This has had the beneficial effect of diminishing the reliance of courts on eyewitness testimony and defendant confessions. PMID:12805857

    In this issue of the Journal, Robert Simon has explored the subject of the place that writing should occupy in the professional life of forensic psychiatrists. We have taken the platform so elegantly constructed by this erudite and prolific author and used it to discuss the quotidian and concrete task of writing the customary forensic psychiatry report. We look to other disciplines for mechanisms to analyze the written forensic report: concepts of voice, portraiture, and narrative. We ultimately conclude that preparing these reports is a complex undertaking and that writing with clarity, precision, and artistry in forensic psychiatry should be viewed as a core competency.

    In the aftermath of a CBRN incident, there is an urgent need to reconstruct events in order to bring the perpetrators to court and to take preventive actions for the future. The challenge is to discriminate, based on available information, between alternative scenarios. Forensic interpretation is used to evaluate to what extent results from the forensic investigation favor the prosecutors' or the defendants' arguments, using the framework of Bayesian hypothesis testing. Recently, several new scientific disciplines have been used in a forensic context. In the AniBioThreat project, the framework was applied to veterinary forensic pathology, tracing of pathogenic microorganisms, and forensic entomology. Forensic entomology is an important tool for estimating the postmortem interval in, for example, homicide investigations as a complement to more traditional methods. In this article we demonstrate the applicability of the Bayesian framework for evaluating entomological evidence in a forensic investigation through the analysis of a hypothetical scenario involving suspect movement of carcasses from a clandestine laboratory. Probabilities of different findings under the alternative hypotheses were estimated using a combination of statistical analysis of data, expert knowledge, and simulation, and entomological findings are used to update the beliefs about the prosecutors' and defendants' hypotheses and to calculate the value of evidence. The Bayesian framework proved useful for evaluating complex hypotheses using findings from several insect species, accounting for uncertainty about development rate, temperature, and precolonization. The applicability of the forensic statistic approach to evaluating forensic results from a CBRN incident is discussed. PMID:23971824

    Shared (Induced) Delusional Disorder commonly occurs in close relationships and involves a varying number of participants who may be nonconsanguineous. The disorder has been associated with forensic and fatal consequences. Its occurrence in three nonrelated, incarcerated individuals is described in this article. This case of folie à trois has forensic implications and raises several questions of ethics that relate to autonomy, confidentiality, safety, and risk estimation. The presentation, management, and outcome of the patients suggest that a high index of suspicion is needed to detect cases in similar settings. The report concludes that the rarity of the disorder in a forensic mental health population may be the result of underdetection, given that conditions are conducive to the development of the disorder. Telltale signs of its manifestation are hypothesized as being responsible for some events in incarcerated populations. Physical separation and antipsychotic medications remain the mainstay of treatment. PMID:16186193

    Fires, their consequences and their investigations, continue to provide forensic scientists, especially those involved in medicolegal investigation (the medical examiner or forensic pathologist), with constant work and variations in problems. The recent history of mass disasters involving high-rise buildings, transport accidents, and arson-related accidents in nightclubs and prisons has emphasized the necessity for corrective and preventive means to ensure safety to the occupants of any of these areas. Problems presented by fires include the determination of the cause of the fire, the identification of the victims, and the cause and manner of their deaths. The motivation of the fire setter and the settlement by the insurance company or legal means are also aspects to be considered. The imperceptible effects of the fires include many other aspects, among which loss of loved ones and family providers and loss of industrial revenue and job potential are all felt. The most frightening development of all, however, is the insidious surfacing of arson as a possible factor in many major fires. The most recent tragedies involving the Stouffer Inn fire and the Hilton International Hotel fire were both related to arsonous acts. The scope of this article is to review the subject as it affects the forensic medical practitioner directly or indirectly so that his or her investigation may be brought to completion in conjunction with other authorities involved in the case.

    We are interested in applying our understanding of actinide chemical structure and bonding to broaden the suite of analytical tools available for nuclear forensic analyses. Uranium- and plutonium-oxide systems form under a variety of conditions, and these chemical species exhibit some of the most complex behavior of metal oxide systems known. No less intriguing is the ability of AnO{sub 2} (An: U, Pu) to form non-stoichiometric species described as AnO{sub 2+x}. Environmental studies have shown the value of utilizing the chemical signatures of these actinide oxides materials to understand transport following release into the environment. Chemical speciation of actinide-oxide samples may also provide clues as to the age, source, process history, or transport of the material. The scientific challenge is to identify, measure and understand those aspects of speciation of actinide analytes that carry information about material origin and history most relevant to forensics. Here, we will describe our efforts in material synthesis and analytical methods development that we will use to provide the fundamental science required to characterize actinide oxide molecular structures for forensics science. Structural properties and initial results to measure structural variability of uranium oxide samples using synchrotron-based X-ray Absorption Fine Structure will be discussed.

    Problematic Internet use appears to be a growing concern in many criminal and civil legal proceedings. Problems range from inappropriate personal use of the Internet in the workplace and excessive use of online games, pornography, and gambling, to cyberbullying among children and adolescents and numerous forms of criminal activity. Forensic psychiatric evaluations may help courts or other agencies to understand individual cases and to discern whether a psychiatric disability may be involved. Furthermore, the forensic psychiatrist may be asked to formulate a prognosis or to suggest which treatments may be helpful. Among the multiple underlying pathophysiologic mechanisms that explain problematic Internet use are: addiction, compulsion, impulse-control problems, and mood disorders. There is no definitive or standard treatment protocol for evaluation or treatment of problematic Internet use per se. A comprehensive evaluation should address the underlying psychopathology or personal problems that prompt or contribute to the problematic Internet use. This article suggests approaches that may help forensic psychiatrists to conduct a thorough evaluation with reasonable treatment recommendations. Different formulations of the problem and a discussion of DSM-IV factors are offered to provide starting points for the evaluation and to help psychiatrists to understand how problematic Internet use may relate to Axis I disorders or other factors.

    Forensic facial reconstruction can be used to identify unknown human remains when other techniques fail. Through this article, we attempt to review the different methods of facial reconstruction reported in literature. There are several techniques of doing facial reconstruction, which vary from two dimensional drawings to three dimensional clay models. With the advancement in 3D technology, a rapid, efficient and cost effective computerized 3D forensic facial reconstruction method has been developed which has brought down the degree of error previously encountered. There are several methods of manual facial reconstruction but the combination Manchester method has been reported to be the best and most accurate method for the positive recognition of an individual. Recognition allows the involved government agencies to make a list of suspected victims’. This list can then be narrowed down and a positive identification may be given by the more conventional method of forensic medicine. Facial reconstruction allows visual identification by the individual’s family and associates to become easy and more definite. PMID:26501035

    The goal of the U.S. Department of Homeland Security (DHS) Nuclear and Radiological Forensics and Attribution Program is to develop the technical capability for the nation to rapidly, accurately, and credibly attribute the origins and pathways of interdicted or collected materials, intact nuclear devices, and radiological dispersal devices. A robust attribution capability contributes to threat assessment, prevention, and deterrence of nuclear terrorism; it also supports the Federal Bureau of Investigation (FBI) in its investigative mission to prevent and respond to nuclear terrorism. Development of the capability involves two major elements: (1) the ability to collect evidence and make forensic measurements, and (2) the ability to interpret the forensic data. The Program leverages the existing capability throughout the U.S. Department of Energy (DOE) national laboratory complex in a way that meets the requirements of the FBI and other government users. At the same time the capability is being developed, the Program also conducts investigations for a variety of sponsors using the current capability. The combination of operations and R&D in one program helps to ensure a strong linkage between the needs of the user community and the scientific development.

  10. Bayesian calibration for forensic age estimation.

    Ferrante, Luigi; Skrami, Edlira; Gesuita, Rosaria; Cameriere, Roberto

    2015-05-10

    Forensic medicine is increasingly called upon to assess the age of individuals. Forensic age estimation is mostly required in relation to illegal immigration and identification of bodies or skeletal remains. A variety of age estimation methods are based on dental samples and use of regression models, where the age of an individual is predicted by morphological tooth changes that take place over time. From the medico-legal point of view, regression models, with age as the dependent random variable entail that age tends to be overestimated in the young and underestimated in the old. To overcome this bias, we describe a new full Bayesian calibration method (asymmetric Laplace Bayesian calibration) for forensic age estimation that uses asymmetric Laplace distribution as the probability model. The method was compared with three existing approaches (two Bayesian and a classical method) using simulated data. Although its accuracy was comparable with that of the other methods, the asymmetric Laplace Bayesian calibration appears to be significantly more reliable and robust in case of misspecification of the probability model. The proposed method was also applied to a real dataset of values of the pulp chamber of the right lower premolar measured on x-ray scans of individuals of known age. PMID:25645903

    Over the past few years, both large multinationals and governments have begun to contribute to even larger projects on biometric devices. Terrorist attacks in America and in other countries have highlighted the need for better identification systems for people as well as improved systems for controlling access to buildings. Another reason for investment in Research and Development in Biometric Devices, is the massive growth in internet-based systems -- whether for e-commerce, e-government or internal processes within organizations. The interface between the system and the user is routinely abused, as people have to remember many complex passwords and handle tokens of various types. In this paper an overview is given of the information that is important to know before an examination of such is systems can be done in a forensic proper way. In forensic evidence with biometric devices the forensic examiner should consider the possibilities of tampering with the biometric systems or the possibilities of unauthorized access before drawing conclusions.

  12. Implant bone integration importance in forensic identification.

    PubMed

    De Angelis, Danilo; Cattaneo, Cristina

    2015-03-01

    Odontological identification consists of the comparison of antemortem dental information regarding a missing person with postmortem data from an unidentified corpse or human remains. Usually, the comparison concerns morphologic features that the operator chooses among all the visible characteristics because of inter-individual uniqueness; for this reason, implants can be of enormous assistance. A case concerning the recovery of a burnt oral implant, connected to a bone fragment, among 2780 charred bone fragments, suspected to have belonged to a victim of homicide, is presented to demonstrate that dental implants and their site of bone integration represent a very precious element for personal forensic identification. Because of their morphological invariability in time and because of their morphologic uniqueness, they were used as evidence to associate unidentified human charred remains to a missing person where DNA analysis failed to do so. The case illustrates the fundamental contribution, not yet described in literature, given by the clinical aspects of tooth replacement with dental implants to a forensic discipline. Clinical practitioners should therefore be aware of the great importance of their work and of dental records in a forensic identification scenario. PMID:25387697

  13. Forensic Entomology in Animal Cruelty Cases.

    PubMed

    Brundage, A; Byrd, J H

    2016-09-01

    Forensic entomology can be useful to the veterinary professional in cases of animal cruelty. A main application of forensic entomology is to determine the minimum postmortem interval by estimating the time of insect colonization, based on knowledge of the rate of development of pioneer colonizers and on insect species succession during decomposition of animal remains. Since insect development is temperature dependent, these estimates require documentation of the environmental conditions, including ambient temperature. It can also aid in the detection and recognition of wounds, as well as estimate the timing of periods of neglect. Knowledge of the geographic distribution of insects that colonize animal remains may suggest that there has been movement or concealment of the carcass or can create associations between a suspect, a victim, and a crime scene. In some instances, it can aid in the detection of drugs or toxins within decomposed or skeletonized remains. During animal cruelty investigations, it may become the responsibility of the veterinary professional to document and collect entomological evidence from live animals or during the necropsy. The applications of forensic entomology are discussed. A protocol is described for documenting and collecting entomological evidence at the scene and during the necropsy, with additional emphasis on recording geographic location, meteorological data, and collection and preservation of insect specimens.

    Forensic Image Databases appear in a wide variety. The oldest computer database is with fingerprints. Other examples of databases are shoeprints, handwriting, cartridge cases, toolmarks drugs tablets and faces. In these databases searches are conducted on shape, color and other forensic features. There exist a wide variety of methods for searching in images in these databases. The result will be a list of candidates that should be compared manually. The challenge in forensic science is to combine the information acquired. The combination of the shape of a partial shoe print with information on a cartridge case can result in stronger evidence. It is expected that searching in the combination of these databases with other databases (e.g. network traffic information) more crimes will be solved. Searching in image databases is still difficult, as we can see in databases of faces. Due to lighting conditions and altering of the face by aging, it is nearly impossible to find a right face from a database of one million faces in top position by a image searching method, without using other information. The methods for data mining in images in databases (e.g. MPEG-7 framework) are discussed, and the expectations of future developments are presented in this study.

    2012-01-01

    Mitochondria's role in crucial metabolic pathways is probably the first answer which comes to our minds for the question: what do these tiny organelles serve for? However, specific features of their DNA made them extremely useful also in the field of anthropology and forensics. MtDNA analyses became a milestone in the complex task of unraveling earliest human migrations. Evidence provided by these experiments left no doubts on modern humans origins pointing to Africa being our cradle. It also contributed to interpretation of putative ways of our dispersal around Asia and Americas thousands years ago. On the other hand, analysis of mtDNA is well established and valuable tool in forensic genetics. When other definitely more popular markers give no answer on identity, it is the time to employ information carried by mitochondria. This chapter summarizes not only current reports on the role of mitochondria in forensics and reconstruction of modern humans phylogeny, but also calls one's attention to a broad range of difficulties and constraints associated with mtDNA analyses.

  16. Digital Forensics as a Surreal Narrative

    NASA Astrophysics Data System (ADS)

    Pollitt, Mark

    Digital forensics is traditionally approached either as a computer science problem or as an investigative problem. In both cases, the goal is usually the same: attempt to locate discrete pieces of information that are probative. In the computer science approach, characteristics of the data are utilized to include or exclude objects, data or metadata. The investigative approach reviews the content of the evidence to interpret the data in the light of known facts and elements of the crime in order to determine probative information or information of lead value. This paper explores two literary theories, narrative theory and surrealism, for potential application to the digital forensic process. Narrative theory focuses on the “story” that is represented by text. At some level, a storage device may be viewed as a series of interweaving, possibly multi-dimensional, narratives. Furthermore, the narratives themselves, coupled with the metadata from the file system and applications, may form a meta-narrative. The literary theory of surrealism, the notion of disjointed elements, can be utilized to derive meaning from forensic evidence. This paper uses a technique known as surrealist games to illustrate the point.

    "Forensic podiatry is defined as the application of sound and researched podiatric knowledge and experience in forensic investigations; to show the association of an individual with a scene of crime, or to answer any other legal question concerned with the foot or footwear that requires knowledge of the functioning foot". Forensic podiatrists can contribute to forensic identification by associating the pedal evidence with the criminal or crime scene. The most common pedal evidence collected from the crime scene is in the form of footprints, shoeprints and their tracks and trails. Forensic podiatrists can establish identity of the individuals from the footprints in many ways. The analysis of bare footprints involves the identification based on the individualistic features like flat footedness, ridges, humps, creases, an extra toe, missing toe, corns, cuts, cracks, pits, deformities, and various features of the toe and heel region. All these individualistic features can link the criminal with the crime. In addition to these, parameters of body size like stature and body weight as well as sex can also be estimated by using anthropometric methods. If a series of footprints are recovered from the crime scene, then parameters of the gait analysis such as stride/step length and general movement of the criminal can be traced. Apart from these, a newly established biometric parameter of the footprints i.e. footprint ridge density can also be evaluated for personal identification. Careful analysis of the footprint ridge density can give an idea about the sex of the criminal whose footprints are recovered at the scene which can further help to reduce the burden of the investigating officer as the investigations then may be directed toward either a male suspect or a female suspect accordingly. This paper highlights various aspects of Forensic Podiatry and discusses the different methods of personal identification related to pedal evidence. PMID:26163192

    2014-05-01

    Wildlife forensic science may not have attained the profile of human identification, yet the scale of criminal activity related to wildlife is extensive by any measure. Service delivery in the arena of wildlife forensic science is often ad hoc, unco-ordinated and unregulated, yet many of those currently dedicated to wildlife conservation and the protection of endangered species are striving to ensure that the highest standards are met. The genetic markers and software used to evaluate data in wildlife forensic science are more varied than those in human forensic identification and are rarely standardised between species. The time and resources required to characterise and validate each genetic maker is considerable and in some cases prohibitive. Further, issues are regularly encountered in the construction of allelic databases and allelic ladders; essential in human identification studies, but also applicable to wildlife criminal investigations. Accreditation and certification are essential in human identification and are currently being strived for in the forensic wildlife community. Examples are provided as to how best practice can be demonstrated in all areas of wildlife crime analysis and ensure that this field of forensic science gains and maintains the respect it deserves. This review is aimed at those conducting human identification to illustrate how research concepts in wildlife forensic science can be used in the criminal justice system, as well as describing the real importance of this type of forensic analysis.

    2016-04-01

    Forensic anthropology is an increasingly developing discipline born about a century ago in the United States with the objective to contribute the knowledge of bone biology and physical anthropology to the emerging needs of the court of law. The development of research in biological and forensic anthropology has made rapid progress worldwide in the past few years, however, in most countries--with the exception of the United States--forensic anthropology work is still considered within the duties of the forensic pathologist. This paper attempts to summarise the history and development of forensic anthropology in Thailand by providing information on past and current research and practice that can help forensic practitioners to apply existing methods in forensic cases and mass disasters. It is hoped that the lessons learned from the tsunami catastrophe and the emerging need for positive identification in medicolegal settings will lead to rapid advances in education, training and professional engagement of anthropologists from the forensic departments and the law enforcement agencies in Thailand.

    2014-01-01

    Traffic accidents have increased in the last decade, pedestrians being the most affected group. At autopsy, it is evident that the most common cause of pedestrian death is central nervous system injury, followed by skull base fractures, internal bleeding, lower limb haemorrhage, skull vault fractures, cervical spinal cord injury and airway compromise. The attribution of accident responsibility can be realised through reconstruction of road accident dynamics, investigation of the scene, survey of the vehicle involved and examination of the victim(s). A case study concerning a car accident where both humans and pets were involved is reported here. Investigation and reconstruction of the crime scene were conducted by a team consisting of forensic pathologists and forensic veterinarians. At the scene investigation, the pedestrian and his dog were recovered on the side of the road. An autopsy and a necropsy were conducted on the man and the dog, respectively. In addition, a complete inspection of the sports utility vehicle (SUV) implicated in the road accident was conducted. The results of the autopsy and necropsy were compared and the information was used to reconstruct the collision. This unusual case was solved through the collaboration between forensic pathology and veterinary forensic medicine, emphasising the importance of this kind of co-operation to solve a crime scene concerning both humans and animals.

  2. You can't do that! Hugo Münsterberg and misapplied psychology.

    PubMed

    Weiss, Kenneth J; Xuan, Yan

    2015-01-01

    This article examines a false start in the application of psychology to the law. While there had been expert testimony from physicians in criminal and civil cases in America since the nineteenth century, forensic psychology first emerged in the early twentieth century. Following European traditions of experimental psychology, Hugo Münsterberg applied the nascent science of memory research to the assessment of witness credibility. A brilliant and popular Harvard professor, Münsterberg touted his technique of word-association to determine truth. Forensic psychology's development was stalled by resistance from within legal authorities, including John Henry Wigmore, the leading expert on evidence. However, Münsterberg was a sensation in popular media. In this article, the authors examine early attempts to import experimental psychology into the courtroom and the arguments against them. Not only were Münsterberg's findings premature, they touched on a forbidden domain for witnesses: fact finding. While sincere, he learned that the determination of truth lay within the province of juries and judges, not psychologists. Thus, the application of psychology to the law was delayed. The authors review the lessons from Münsterberg's false start and comment on developments in the admissibility of scientific testimony. PMID:26329983

    Next-generation sequencing (NGS) technology, with its high-throughput capacity and low cost, has developed rapidly in recent years and become an important analytical tool for many genomics researchers. New opportunities in the research domain of the forensic studies emerge by harnessing the power of NGS technology, which can be applied to simultaneously analyzing multiple loci of forensic interest in different genetic contexts, such as autosomes, mitochondrial and sex chromosomes. Furthermore, NGS technology can also have potential applications in many other aspects of research. These include DNA database construction, ancestry and phenotypic inference, monozygotic twin studies, body fluid and species identification, and forensic animal, plant and microbiological analyses. Here we review the application of NGS technology in the field of forensic science with the aim of providing a reference for future forensics studies and practice. PMID:25462152

    PubMed

    Forrest, Alexander S

    2012-03-01

    Forensic odontology is the application of dental expertise to legal issues. Commonly, it involves the comparison of dental records of a missing person with a deceased individual for the purposes of forensic personal identification, either in a single case, or as part of the response to an event involving multiple simultaneous fatalities (Disaster Victim Identification, or DVI). It may also involve studies to determine the age of an individual, which may be required as part of a forensic identification process, or for another legal purpose such as the determination of legal responsibility, or in connection with immigration. This report examines the types of radiological information currently used in such forensic studies, and discusses how this information may be accessed or recorded, as well as the techniques that are commonly applied to the radiological data to reach a satisfactory outcome for application in forensic casework.

    The challenge in achieving an ideal state of justice is that each "proof" has the highest degree of reliability. This is the main responsibility of the forensic scientist. Up to now, criminal investigations in Mexico have been supported by forensic work from a wide variety of disciplinary backgrounds that give testimony in a particular area, even though they may have become forensic witnesses in a complementary and experiential manner. In January 2013, the Universidad Nacional Autónoma de México (UNAM) approved the "Forensic Science" undergraduate program that, in collaboration with various academic entities and government institutions, will develop forensic scientists trained in science, law, and criminology. This is focused on contributing to the national demand that the justice system has more elements to procure and administer justice in dealing with crime. PMID:24481439

  6. Forensic uses of research biobanks: should donors be informed?

    PubMed

    Dranseika, Vilius; Piasecki, Jan; Waligora, Marcin

    2016-03-01

    Occasional reports in the literature suggest that biological samples collected and stored for scientific research are sometimes accessed and used for a variety of forensic purposes. However, donors are almost never informed about this possibility. In this paper we argue that the possibility of forensic access may constitute a relevant consideration at least to some potential research subjects in deciding whether to participate in research. We make the suggestion that if some type of forensic access to research collections is likely to be perceived by the subjects as a reason against donating their biological materials, there are good ethical reasons to make this type of access impossible or at least severely restricted. We also provide an ethical argument for the claim that, if a total ban on this type of forensic access cannot be achieved, potential research subjects should be informed about the extent to which this type of forensic access is possible.

  7. First Digit Law and Its Application to Digital Forensics

    NASA Astrophysics Data System (ADS)

    Shi, Yun Q.

    Digital data forensics, which gathers evidence of data composition, origin, and history, is crucial in our digital world. Although this new research field is still in its infancy stage, it has started to attract increasing attention from the multimedia-security research community. This lecture addresses the first digit law and its applications to digital forensics. First, the Benford and generalized Benford laws, referred to as first digit law, are introduced. Then, the application of first digit law to detection of JPEG compression history for a given BMP image and detection of double JPEG compressions are presented. Finally, applying first digit law to detection of double MPEG video compressions is discussed. It is expected that the first digit law may play an active role in other task of digital forensics. The lesson learned is that statistical models play an important role in digital forensics and for a specific forensic task different models may provide different performance.

  8. Nuclear Forensic Inferences Using Iterative Multidimensional Statistics

    SciTech Connect

    Robel, M; Kristo, M J; Heller, M A

    2009-06-09

    Nuclear forensics involves the analysis of interdicted nuclear material for specific material characteristics (referred to as 'signatures') that imply specific geographical locations, production processes, culprit intentions, etc. Predictive signatures rely on expert knowledge of physics, chemistry, and engineering to develop inferences from these material characteristics. Comparative signatures, on the other hand, rely on comparison of the material characteristics of the interdicted sample (the 'questioned sample' in FBI parlance) with those of a set of known samples. In the ideal case, the set of known samples would be a comprehensive nuclear forensics database, a database which does not currently exist. In fact, our ability to analyze interdicted samples and produce an extensive list of precise materials characteristics far exceeds our ability to interpret the results. Therefore, as we seek to develop the extensive databases necessary for nuclear forensics, we must also develop the methods necessary to produce the necessary inferences from comparison of our analytical results with these large, multidimensional sets of data. In the work reported here, we used a large, multidimensional dataset of results from quality control analyses of uranium ore concentrate (UOC, sometimes called 'yellowcake'). We have found that traditional multidimensional techniques, such as principal components analysis (PCA), are especially useful for understanding such datasets and drawing relevant conclusions. In particular, we have developed an iterative partial least squares-discriminant analysis (PLS-DA) procedure that has proven especially adept at identifying the production location of unknown UOC samples. By removing classes which fell far outside the initial decision boundary, and then rebuilding the PLS-DA model, we have consistently produced better and more definitive attributions than with a single pass classification approach. Performance of the iterative PLS-DA method

  9. The forensic validity of visual analytics

    NASA Astrophysics Data System (ADS)

    Erbacher, Robert F.

    2008-01-01

    The wider use of visualization and visual analytics in wide ranging fields has led to the need for visual analytics capabilities to be legally admissible, especially when applied to digital forensics. This brings the need to consider legal implications when performing visual analytics, an issue not traditionally examined in visualization and visual analytics techniques and research. While digital data is generally admissible under the Federal Rules of Evidence [10][21], a comprehensive validation of the digital evidence is considered prudent. A comprehensive validation requires validation of the digital data under rules for authentication, hearsay, best evidence rule, and privilege. Additional issues with digital data arise when exploring digital data related to admissibility and the validity of what information was examined, to what extent, and whether the analysis process was sufficiently covered by a search warrant. For instance, a search warrant generally covers very narrow requirements as to what law enforcement is allowed to examine and acquire during an investigation. When searching a hard drive for child pornography, how admissible is evidence of an unrelated crime, i.e. drug dealing. This is further complicated by the concept of "in plain view". When performing an analysis of a hard drive what would be considered "in plain view" when analyzing a hard drive. The purpose of this paper is to discuss the issues of digital forensics and the related issues as they apply to visual analytics and identify how visual analytics techniques fit into the digital forensics analysis process, how visual analytics techniques can improve the legal admissibility of digital data, and identify what research is needed to further improve this process. The goal of this paper is to open up consideration of legal ramifications among the visualization community; the author is not a lawyer and the discussions are not meant to be inclusive of all differences in laws between states and

    Victimization by sexual assault has become not only a public health and safety issue but a way of life for many in Colombia. Poverty, gender inequality, and a lack of family and community support contribute to the cycle of sexual violence. Ineffective medico-legal systems have added to a rate of 93% for sex crimes that go without arrest or prosecution in Bogotá, the capital. Collaborative efforts are underway between the United States and Colombian governments to change the criminal justice system and strengthen forensic investigation of sex crimes in Colombia.

    NASA Technical Reports Server (NTRS)

    Ingham, J. D.; Lawson, D. D.

    1973-01-01

    In crime laboratories one of the most difficult operations is to determine unequivocally whether or not two samples of evidence of the same type were originally part of the same thing or were from the same source. It has been found that high temperature thermoluminescence (room temperature to 723 K) can be used for comparisons of this type, although work to date indicates that there is generally a finite probability for coincidental matching of glass or soil samples. Further work is required to determine and attempt to minimize these probabilities for different types of materials, and to define more clearly the scope of applicability of thermoluminescence to actual forensic situations.

    Two forensic dental cases from Norway are presented. The first case, in which a body was found on the seabed, illustrates that identification may give rise to suspicion of murder. In this case, the suspicion proved to be justified. The Scandinavian identification forms are presented. The second case is unusual in that tooth marks in bottle caps linked a burglar to the scene of the crime. Tooth marks for comparison were found in a police car where the suspect had opened a soft-drink bottle with his teeth. Comparison microscopy was used. PMID:7234809

  15. Digital image forensics for photographic copying

    NASA Astrophysics Data System (ADS)

    2012-03-01

    Image display technology has greatly developed over the past few decades, which make it possible to recapture high-quality images from the display medium, such as a liquid crystal display(LCD) screen or a printed paper. The recaptured images are not regarded as a separate image class in the current research of digital image forensics, while the content of the recaptured images may have been tempered. In this paper, two sets of features based on the noise and the traces of double JPEG compression are proposed to identify these recaptured images. Experimental results showed that our proposed features perform well for detecting photographic copying.

    The objective of the present study was to develop the standardized approach to the evaluation of the character of injurious exposure with a view to objective interpretation of the conditions of injury formation and the properties of the traumatic agent. The main attention was given to such parameters of the injurious exposure as loading conditions (mass, speed, direction) and the surface properties of the traumatic agent (area, shape, hardness). It is expected that the use of the proposed system for the evaluation of the injurious exposure in the practical work of forensic medical experts will enhance the reliability of their conclusions and help to avoid mistakes.

    2012-04-01

    The Center for Disaster Management and Risk Reduction Technology (CEDIM, www.cedim.de) - an interdisciplinary research center founded by the German Research Centre for Geoscience (GFZ) and Karlsruhe Institute of Technology (KIT) - has embarked on a new style of disaster research known as Forensic Disaster Analysis. The notion has been coined by the Integrated Research on Disaster Risk initiative (IRDR, www.irdrinternational.org) launched by ICSU in 2010. It has been defined as an approach to studying natural disasters that aims at uncovering the root causes of disasters through in-depth investigations that go beyond the reconnaissance reports and case studies typically conducted after disasters. In adopting this comprehensive understanding of disasters CEDIM adds a real-time component to the assessment and evaluation process. By comprehensive we mean that most if not all relevant aspects of disasters are considered and jointly analysed. This includes the impact (human, economy, and infrastructure), comparisons with recent historic events, social vulnerability, reconstruction and long-term impacts on livelihood issues. The forensic disaster analysis research mode is thus best characterized as "event-based research" through systematic investigation of critical issues arising after a disaster across various inter-related areas. The forensic approach requires (a) availability of global data bases regarding previous earthquake losses, socio-economic parameters, building stock information, etc.; (b) leveraging platforms such as the EERI clearing house, relief-web, and the many sources of local and international sources where information is organized; and (c) rapid access to critical information (e.g., crowd sourcing techniques) to improve our understanding of the complex dynamics of disasters. The main scientific questions being addressed are: What are critical factors that control loss of life, of infrastructure, and for economy? What are the critical interactions

    Gender differences in substance use/abuse have been the focus of research in the last 15 years. Initiation, use patterns, acceleration of disease course, and help-seeking patterns are known to be influenced by gender differences with regard to biological, psychological, cultural and socioeconomic factors. This paper presents a systematic review of published data on gender differences in the use/abuse of psychoactive and psychotic drugs, focusing on the importance of a multidisciplinary approach. The basis for this paper was obtained by Medline searches using the search terms "human" and "gender", combined with individual drug names or "drugs of abuse". The reference lists of these papers were further checked for other relevant studies. The gender difference in drug abuse is more evident in adults than in adolescents (13-19 years): adult men are 2-3 times more likely than women to develop drug abuse/dependence disorders and approximately 4 times as likely to have an alcohol use disorder. Such prevalence rates have not been observed in adolescents. Differences between men and women involve: (i) the biological response to the drug, (ii) the progression to drug dependence, and (iii) the comorbid psychiatric diagnoses, which may be due to both sociocultural factors and innate biological differences. A crucial role played by ovarian hormones (oestrogens and progesterone) has been documented in both human and animal model studies. Epidemiological data on how particular psychobiological and physiological characteristics in females influence vulnerability to both drug addiction and toxicological consequences of drugs are still in their infancy. Significant gaps remain in our knowledge, which are primarily attributable to the lack of empirical data that only a systematic and multidisciplinary approach to the topic can generate. The introduction of gender into forensic toxicological evaluations may help elucidate the relationship between the body's absorption of abused drugs

  4. Mass violence and mental health--a view from forensic psychiatry.

    2007-06-01

    The objectives of this paper are to develop insights into the mind of the terrorist, to conduct a review of health impacts on the health of populations, especially from the point of view of mental health impacts caused by terrorist attacks and to discern the role to be played by forensic psychiatry in emergencies caused by terrorist actions. These objectives are developed at the population level and at the individual level from the point of view of a description of the terrorist and of victim's need for forensic intervention and representation. On entrance, the paper starts with a general frame of definitions and a historical overview of terrorism as an ancient, purposeful, political tool used to change a situation objectionable to the terrorist group via intimidation of a captive population. People are used as expendable pawns and become psychologically captive to the aims of the terrorist group. As well, the paper reviews the new reality of bioterrorism and the use of improved technologies to inflict expensive damage to national infrastructures and massive loss of life. PMID:17566899

  5. The management of domain irrelevant context information in forensic handwriting examination casework.

    PubMed

    Found, Bryan; Ganas, John

    2013-06-01

    That domain irrelevant context information can potentially bias human decision making processes is accepted in the psychological sciences. Although many forensic pattern examination sciences use human perceptual and cognitive processes almost exclusively to form opinions regarding evidence, we have been slow to engage with any procedure that might control for any potential effects associated with context information. The critics of pattern evidence have described how opinions may be unintentionally incorrectly formed and how bodies of evidential information might conspire to form cases where the sum of the totality of the evidence may be significantly more than its specialist parts. Given the body of evidence supporting the potentially serious implications of domain irrelevant information, it was decided to introduce a context management scheme at the Document Examination Unit of the Victoria Police Forensic Services Department. Existing laboratory wide evidence submission procedures were modified in the scheme such that, as far as was agreed to be practical, all handwriting cases were stripped of all but essential information for carrying out examination and comparison tasks. As yet no negative outcomes have been reported as a result of the scheme implementation. PMID:23601722

    This study investigated criminological, psychopathological, and victimological profiles of intimate partner violence (IPV) perpetrators in a sample of 119 Dutch female and male forensic psychiatric outpatients aged 18 to 58 years. In addition, differences in criminological, psychopathological, and victimological factors between IPV perpetrators (n = 61, 51.3%) and non-intimate violence (NIV) perpetrators (n = 58, 48.7%) were examined. All data, including information on demographics, criminal history, history of psychological, sexual, and physical victimization during childhood or adolescence, family history of psychopathology, history of psychopathology in childhood and adolescence, and mental disorders, were derived from archival electronic medical records. Mental disorders were measured using structured psychiatric interviews and final consensus diagnoses were established during weekly case consultations. Both IPV and NIV perpetrators displayed high rates of criminal history, psychopathology, and previous victimization, but the two groups did not differ in these factors with two exceptions. IPV perpetrators were significantly more likely to have higher rates of previous physical victimization and intermittent explosive disorder than NIV perpetrators. The current study suggests that a history of physical victimization and intermittent explosive disorder are specific characteristics of IPV perpetrators in a forensic psychiatric outpatient setting. Future research should focus on mechanisms explaining the association of childhood victimization and IPV and increase our understanding of the role of intermittent explosive disorder in IPV.

  8. Forensic acoustics: An opportunity to educate

    NASA Astrophysics Data System (ADS)

    Brooks, Bennett

    2003-10-01

    Forensic science is narrowly defined by some as the gathering of evidence to be used in a criminal court proceeding. However, the word ``forensic'' broadly pertains to arguments made in any public forum. Those acousticians engaged in expert witness service may work in a variety of settings that address the interests of the general public. These can include quasilegal local administrative public hearings, conducted at school board or planning and zoning meetings, civil legal actions, and rarely, a criminal trial. When presenting complex scientific arguments in a public forum, the reception with which that information is met can strongly depend upon the self-interest of meeting participants, as well as the common skepticism toward all things technical. To successfully gain favor for a particular viewpoint, the target audience (board commissioners, judges, juries) must be sufficiently educated to understand the methods of acquiring valid acoustical data, and the impact of acoustics to the situation in question. The challenge is to present credible information with just enough detail to persuade, but not overwhelm, the decision maker. Illustrative case studies will be discussed.

    Kraetzer, Christian; Qian, Kun; Dittmann, Jana

    2012-03-01

    In this paper, we extend an existing context model for statistical pattern recognition based microphone forensics by: first, generating a generalized model for this process and second, using this general model to construct a complex new application scenario model for microphone forensic investigations on the detection of playback recordings (a.k.a. replays, re-recordings, double-recordings). Thereby, we build the theoretical basis for answering the question whether an audio recording was made to record a playback or natural sound. The results of our investigations on the research question of playback detection imply that it is possible with our approach on our evaluation set of six microphones. If the recorded sound is not modified prior to playback, we achieve in our tests 89.00% positive indications on the correct two microphones involved. If the sound is post-processed (here, by normalization) this figure decreases (in our normalization example to 36.00%, while another 50.67% of the tests still indicate two microphones, of which one has actually not been involved in the recording and playback recording process).

    Measuring various items (evidence) at the scene of an investigation, exposed to the elements, is an instrumental part of systematic forensic science. The key to these measurements often rest on rulers, and a knowledge of their limitations is vital to their appropriate application. The aim of this study was to test forensic ruler accuracy and photographic distortion under conditions that simulate common use to provide a foundational basis for baseline accuracy of their use. A series of ABFO rulers from 2 anonymous manufactures were tested against gold standards for accuracy at various temperatures (-14, 0, 25 and 40 °C). At the same time a series of rulers were photographed at different angulations to test reproducibility and angular distortion. At room temperature a variation of 0.28% in the dimensions of the rulers were found with larger distortions at colder temperatures. Photographs taken with the camera above the rulers suffered the least distortion (approximately 6-10°) and there was no difference over time, nor with ruler background colour. The results from this study show that further investigation is required into preventing angular distortion, and show the need for increased training to those who would be in a situation requiring them to document the scene of a crime.

    2009-04-01

    Patients suffer preventable harm from their medical treatment. The traditional approaches to investigating medical treatment related deaths are the 'hospital mortality audit' and legal or coroners investigation. The aim is to describe how the patient safety movement in the late 1990s is changing traditional approaches to the investigation. The prevention of medical treatment related death involves an investigation as one of five major stages. These are Stage I Preparedness; Stage II Recognition and reporting; Stage III Investigation and analysis; Stage IV Findings and recommendations; and Stage V Response. The influence of the patient safety approach is considered at each stage with a particular focus on Stage I. It is at this stage that the concepts of clinical governance, culture and systems of care have a major influence on the nature of an investigation. The genesis of the modern forensic investigation into medical treatment related deaths in Victoria, Australia is described. The formation of the Clinical Liaison Service incorporates concepts from the patient safety approach with clinical staff to transform the traditional Coroner's investigation. Benefits of a modern forensic investigation include improving appropriateness of cases proceeding to investigation and a focus on prevention. Achieving a reduction in medical treatment related death requires substantial shifts towards an approach consistent with the patient safety. PMID:19278889

    2015-03-01

    Medicine counterfeiting is a crime that has increased in recent years and now involves the whole world. Health and economic repercussions have led pharmaceutical industries and agencies to develop many measures to protect genuine medicines and differentiate them from counterfeits. Detecting counterfeit is chemically relatively simple for the specialists, but much more information can be gained from the analyses in a forensic intelligence perspective. Analytical data can feed criminal investigation and law enforcement by detecting and understanding the criminal phenomenon. Profiling seizures using chemical and packaging data constitutes a strong way to detect organised production and industrialised forms of criminality, and is the focus of this paper. Thirty-three seizures of a commonly counterfeited type of capsule have been studied. The results of the packaging and chemical analyses were gathered within an organised database. Strong linkage was found between the seizures at the different production steps, indicating the presence of a main counterfeit network dominating the market. The interpretation of the links with circumstantial data provided information about the production and the distribution of counterfeits coming from this network. This forensic intelligence perspective has the potential to be generalised to other types of products. This may be the only reliable approach to help the understanding of the organised crime phenomenon behind counterfeiting and to enable efficient strategic and operational decision making in an attempt to dismantle counterfeit network.

    Bloodstains at crime scenes are among the most important types of evidence for forensic investigators. They can be used for DNA-profiling for verifying the suspect's identity or for pattern analysis in order to reconstruct the crime. However, until now, using bloodstains to determine the time elapsed since the crime was committed is still not possible. From a criminalistic point of view, an accurate estimation of when the crime was committed enables to verify witnesses' statements, limits the number of suspects and assesses alibis. Despite several attempts and exploration of many technologies during a century, no method has been materialized into forensic practice. This review gives an overview of an extensive search in scientific literature of techniques that address the quest for age determination of bloodstains. We found that most techniques are complementary to each other, in short as well as long term age determination. Techniques are compared concerning their sensitivity for short and long term ageing of bloodstains and concerning their possible applicability to be used on a crime scene. In addition, experimental challenges like substrate variation, interdonor variation and environmental influences are addressed. Comparison of these techniques contributes to our knowledge of the physics and biochemistry in an ageing bloodstain. Further improvement and incorporation of environmental factors are necessary to enable age determination of bloodstains to be acceptable in court. PMID:21868178

    Nuclear forensics includes the study of materials used for the attribution a nuclear event. Analysis of the nuclear reaction products resulting both from the weapon and the material in the vicinity of the event provides data needed to identify the source of the nuclear material and the weapon design. The spectral information of the neutrons produced by the event provides information on the weapon configuration. The lithium battery provides a unique platform for nuclear forensics, as the Li-6 content is highly sensitive to neutrons, while the battery construction consists of various layers of materials. Each of these materials represents an element for a threshold detector scheme, where isotopes are produced in the battery components through various nuclear reactions that require a neutron energy above a fundamental threshold energy. This study looks into means for extracting neutron spectral information by understanding the isotopic concentration prior to and after exposure. The radioisotopes decay through gamma and beta emission, and radiation spectrometers have been used to measure the radiation spectra from the neutron exposed batteries. The batteries were exposed to various known neutron fields, and analysis was conducted to reconstruct the incident neutron spectra. This project is supported by the Defense Threat Reduction Agency, grant number HDTRA1-11-1-0028.

  15. Forensic document analysis using scanning microscopy

    2009-05-01

    The authentication and identification of the source of a printed document(s) can be important in forensic investigations involving a wide range of fraudulent materials, including counterfeit currency, travel and identity documents, business and personal checks, money orders, prescription labels, travelers checks, medical records, financial documents and threatening correspondence. The physical and chemical characterization of document materials - including paper, writing inks and printed media - is becoming increasingly relevant for law enforcement agencies, with the availability of a wide variety of sophisticated commercial printers and copiers which are capable of producing fraudulent documents of extremely high print quality, rendering these difficult to distinguish from genuine documents. This paper describes various applications and analytical methodologies using scanning electron miscoscopy/energy dispersive (x-ray) spectroscopy (SEM/EDS) and related technologies for the characterization of fraudulent documents, and illustrates how their morphological and chemical profiles can be compared to (1) authenticate and (2) link forensic documents with a common source(s) in their production history.

  16. Accurate pose estimation for forensic identification

    In forensic authentication, one aims to identify the perpetrator among a series of suspects or distractors. A fundamental problem in any recognition system that aims for identification of subjects in a natural scene is the lack of constrains on viewing and imaging conditions. In forensic applications, identification proves even more challenging, since most surveillance footage is of abysmal quality. In this context, robust methods for pose estimation are paramount. In this paper we will therefore present a new pose estimation strategy for very low quality footage. Our approach uses 3D-2D registration of a textured 3D face model with the surveillance image to obtain accurate far field pose alignment. Starting from an inaccurate initial estimate, the technique uses novel similarity measures based on the monogenic signal to guide a pose optimization process. We will illustrate the descriptive strength of the introduced similarity measures by using them directly as a recognition metric. Through validation, using both real and synthetic surveillance footage, our pose estimation method is shown to be accurate, and robust to lighting changes and image degradation.

    The objective of the present study was to develop the universal approach to the quantitative determination of acetylsalicylic acid in biological tissues and fluids to be applied in the practice of forensic chemical expertise with the use of thin-layer chromatography, gas chromatography and mass spectrometry, low-pressure column chromatography, and spectrophotometry. A system of solvents consisting of acetone and ethyl acetate (7:3) was proposed as a universal agent for extracting acetylsalicylic acid from the cadaveric tissues and blood. It was shown that acetylsalicylic acid and its principal metabolite, salicylic acid, can be purified from the endogenous admixtures present in the biological materials by column chromatography on silica gel L 40/100 mcm. Salicylic acid in extracts from biological materials was identified and quantified with the use of thin-layer chromatography, gas chromatography/mass spectrometry, and electronic spectrophotometry. The method for forensic chemical investigation of acetylsalicylic acid has been developed and applied in the analysis of the material provided for expertise. PMID:26856059

  18. Cyber Forensics Ontology for Cyber Criminal Investigation

    NASA Astrophysics Data System (ADS)

    Park, Heum; Cho, Sunho; Kwon, Hyuk-Chul

    We developed Cyber Forensics Ontology for the criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by evidence from digital data and cyber space. Accordingly, it is difficult to determine relational crime types and collect evidence. Therefore, we considered the classifications of cyber crime, the collection of evidence in cyber space and the application of laws to cyber crime. In order to efficiently investigate cyber crime, it is necessary to integrate those concepts for each cyber crime-case. Thus, we constructed a cyber forensics domain ontology for criminal investigation in cyber space, according to the categories of cyber crime, laws, evidence and information of criminals. This ontology can be used in the process of investigating of cyber crime-cases, and for data mining of cyber crime; classification, clustering, association and detection of crime types, crime cases, evidences and criminals.

    Hinchliffe, J

    2011-03-12

    This series is based upon fact, experience, and some personal views of the author and gives a brief glimpse of forensic odontological issues with regard to the identification of human remains (to include mass fatality incidents), biting injuries and child abuse. The aim of the first paper is to give the reader greater understanding of the role of the forensic odontologist in the identification of human remains, and emphasise the importance of keeping good quality, accurate and comprehensive dental records. Identification of the deceased greatly assists families and friends at this difficult time, as well as aiding law enforcement agencies; getting it wrong is devastating to families and unacceptable. The dental identification process must be carefully undertaken and relies upon the comparison of information from the antemortem record with findings from the postmortem examination, and the efficiency of this process is dependent on the quality and availability of the dental record. As dental team members it is our responsibility to keep and maintain accurate records of our patients. The resilience of the dental structures to postmortem assault, denture labelling, and teeth as a source of DNA, all contribute to making identification successful. Dental identification is widely used, not only in the single fatality situation, but also in mass fatality incidents and cases of missing persons. PMID:21394152

    This study reports on research undertaken to identify the skills and competencies of forensic psychiatric nurses working in secure psychiatric services in the UK. The rationale for this research is the lack of clarity in the role definition of nurses working in these environments and the specific content that may underscore the curriculum for training forensic nurses. Over 3300 questionnaires were distributed to forensic psychiatric nurses, non-forensic psychiatric nurses and other disciplines and information obtained on (1) the perceived clinical problems that give forensic nurses the most difficulty; (2) the skills best suited to overcome those problems; and (3) the priority aspects of clinical nursing care that needs to be developed. A 35% response rate was obtained with 1019 forensic psychiatric nurses, 110 non-forensic psychiatric nurses and 43 other disciplines. The results highlighted a 'top ten' list of main problems with possible solutions and main areas for development. The conclusions drawn include a focus on skills and competencies regarding the management of personality disorders and the management of violence and aggression. PMID:18211560

    2013-09-01

    The Department of Forensic Entomology (Institut de Recherche Criminelle de la Gendarmerie Nationale, France) was accredited by the French Committee of Accreditation (Cofrac's Healthcare section) in October 2007 on the basis of NF EN ISO/CEI 17025 standard. It was the first accreditation in this specific field of forensic sciences in France and in Europe. The present paper introduces the accreditation process in forensic entomology (FE) through the experience of the Department of Forensic Entomology. Based upon the identification of necrophagous insects and the study of their biology, FE must, as any other expertise work in forensic sciences, demonstrate integrity and good working practice to satisfy both the courts and the scientific community. FE does not, strictly speaking, follow an analytical method. This could explain why, to make up for a lack of appropriate quality reference, a specific documentation was drafted and written by the staff of the Department of Forensic Entomology in order to define working methods complying with quality standards (testing methods). A quality assurance system is laborious to set up and maintain and can be perceived as complex, time-consuming and never-ending. However, a survey performed in 2011 revealed that the accreditation process in the frame of expertise work has led to new well-defined working habits, based on an effort at transparency. It also requires constant questioning and a proactive approach, both profitable for customers (magistrates, investigators) and analysts (forensic entomologists). PMID:23842668

    2014-02-01

    In the last years many image forensic (IF) algorithms have been proposed to reveal traces of processing or tampering. On the other hand, Anti-Forensic (AF) tools have also been developed to help the forger in removing editing footprints. Inspired by the fact that it is much harder to commit a perfect crime when the forensic analyst uses a multi-clue investigation strategy, we analyse the possibility o ered by the adoption of a data fusion framework in a Counter-Anti-Forensic (CAF) scenario. We do so by adopting a theoretical framework, based on Dempster-Shafer Theory of Evidence, to synergically merge information provided by IF tools and CAF tools, whose goal is to reveal traces introduced by anti-forensic algorithms. The proposed system accounts for the non-trivial relationships between IF and CAF techniques; for example, in some cases the outputs from the former are expected to contradict the output from the latter. We evaluate the proposed method within a representative forensic task, that is splicing detection in JPEG images, with the forger trying to conceal traces using two di erent counter-forensic methods. Results show that decision fusion strongly limits the e ectiveness of AF methods.

    Criminal responsibility evaluation is a very complex and controversial issue due to the gravity of its consequences. Polish legislation allows courts to request multiple sanity evaluations. The purpose of this study was to assess the extent of agreement on sanity evaluations in written evidence provided by experts of criminal cases in Poland. A total of 381 forensic evaluation reports addressing 117 criminal defendants were analysed. In sixty eight cases, there was more than one forensic evaluation report containing an assessment of legal sanity, including forty one cases containing two assessments of criminal responsibility, seventeen containing three assessments, eight containing four assessments and two containing five assessments. We found that in 47% of the cases containing more than one sanity assessment, the initial criminal responsibility assessment was changed after a subsequent forensic evaluation. The agreement between repeated criminal responsibility evaluations was found to be fair. This study found a strong correlation between the number of forensic reports and the number of contradictory sanity assessments. There were fewer forensic opinions involved in the cases in which the same conclusion regarding criminal responsibility was reached in subsequent forensic evaluation reports compared to the cases in which more forensic opinions were involved. There is a clear need for further research in this area, and it is necessary to standardise criminal responsibility evaluations in order to improve their reliability and to shorten the legal proceedings.

    The Internet has become a very powerful and inexpensive tool for the free distribution of knowledge and information. It is a learning and research tool, a virtual library without borders and membership requirements, a help desk, and a publication house providing newspapers with current information and journals with instant publication. Very soon, when live audio and video transmission is perfected, the Internet (popularly referred to as the Net) also will be a live classroom and everyday conference site. This article provides a brief overview of the basic structure and essential components of the Internet. A limited number of home pages/Web sites that are already made available on the Net by scientists, laboratories, and colleges in the forensic science community are presented in table forms. Home pages/Web sites containing useful information pertinent to different disciplines of forensic science are also categorized in various tables. The ease and benefits of the Internet use are exemplified by the author's personal experience. Currently, only a few forensic scientists and institutions have made their presence felt. More participation and active contribution and the creation of on-line searchable databases in all specialties of forensic science are urgently needed. Leading forensic journals should take the lead and create on-line searchable indexes with abstracts. Creating Internet repositories of unpublished papers is an idea worth looking into. Leading forensic science institutions should also develop use of the Net to provide training and retraining opportunities for forensic scientists. PMID:26269943

  10. Personality theory, abnormal psychology, and psychological measurement. A psychological behaviorism.

    PubMed

    Staats, A W

    1993-01-01

    Behaviorism, because it has not had a theory of personality, has been separated from the rest of psychology, unable in large part to draw from or contribute to it. Traditional psychology has not had a theory of personality that says what personality is, how it comes about, or how it functions. An antagonism has resulted that weakens rather than complements each tradition. Psychological behaviorism presents a new type of theory of personality. Derived from experimentation, it is constructed from basic theories of emotion, language, and sensory-motor behavior. It says personality is composed of learned basic behavioral repertoires (BBRs) that affect behavior. Personality measurement instruments are analyzed in terms of the BBRs, beginning the behaviorization of this field and calling for much additional research. These multilevel developments are then basic in psychological behaviorism's theory of abnormal behavior and of clinical treatment. The approach opens many new avenues of empirical and theoretical work. PMID:8439278

    Geoscience methods are increasingly being utilised in criminal, environmental and humanitarian forensic investigations, and the use of such methods is supported by a growing body of experimental and theoretical research. Geoscience search techniques can complement traditional methodologies in the search for buried objects, including clandestine graves, weapons, explosives, drugs, illegal weapons, hazardous waste and vehicles. This paper details recent advances in search and detection methods, with case studies and reviews. Relevant examples are given, together with a generalised workflow for search and suggested detection technique(s) table. Forensic geoscience techniques are continuing to rapidly evolve to assist search investigators to detect hitherto difficult to locate forensic targets.

    In the last two decades, forensic psychotherapy has become a specialised area of scholarship, predominantly in the UK and Germany. However, scientific research with respect to set goals, methods and the application of treatments has been heterogeneous and not very extensive. Focussing on offender treatment, the status quo of research schemes based on clinical experience is discussed, and a strategy is suggested as how to develop a research framework for forensic psychotherapy which makes use of the specific methods and treatment interventions applied in this field. It is concluded that forensic psychotherapy research will greatly benefit from the methodological framework of general psychotherapy research, especially when competing for scarce financial resources.

    With more people engaging in recreational scuba diving, fatalities from this sport are encountered by forensic investigators. There is a plethora of factors contributing to death and the investigator must be acquainted with how to elucidate them. The emphasis is on a multi-disciplinary approach that involves co-divers and instructors, the rescue team, the police, forensic scientists, diving equipment suppliers, underwater physiologists and physicians, decompression chamber personnel, general practitioners, relatives and the forensic pathologist. This report presents the various factors contributing to scuba diving deaths and suggests how to conduct such investigations. PMID:7606500

    This article addresses unique biases that arise in the assessment of sexual harassment claims by forensic psychiatrists. These include gender biases, diagnostic biases, sociopolitical biases, and bias that arises from lack of knowledge regarding sexual harassment or lack of formal psychiatric training. Forensic psychiatrists are ethically obligated to strive for objectivity and honesty in their assessments. By becoming aware of these biases and attempting to minimize them, we can meet our ethical obligations as forensic psychiatrists. In addition, we can provide more credible and valuable assessments to the courts in this increasingly litigated and partisan issue. PMID:9894213

    Neuropsychologists are frequently retained by attorneys or the courts to assist in the resolution of legal disputes. Yet, an outcomes assessment demonstrating the utility of neuropsychological evaluations in the forensic arena has not been implemented, nor has a method for conducting an outcomes assessment of forensic neuropsychology been delineated. This article offers recommendations and considerations for the formulation of outcomes assessments. These include defining an outcomes assessment, identifying the consumers of forensic neuropsychological assessments, and specifying potential moderator and dependent variables in the context of study designs that may be feasibly implemented. Moreover, the ethical implications of outcomes assessments are discussed. PMID:16318446

    For the past 27 years, has been committed to publishing empirical research relevant to clinical assessment of basic and applied cognition, personality, interpersonal behavior, psychopathology, forensics, and biological psychology. There is growing interest in the use of patient-centered outcomes in medical/surgical care and for measuring health care performance. Patient-centered outcome measures complement traditional clinical outcomes of morbidity and mortality, capturing the patient's perspective regarding their health and its treatment. In this issue, we highlight 11 articles that address different aspects of such work. The articles in this special issue represent both the depth and breadth of the opportunities that exist for psychological assessment in the health setting. While there are countless patient-centered measures currently in use to measure health and health outcomes, the evidence base for their use can be quite variable (Butt, 2016). The hope is that future issues of will highlight more work in this area. (PsycINFO Database Record PMID:27536998

  6. My-Forensic-Loci-queries (MyFLq) framework for analysis of forensic STR data generated by massive parallel sequencing.

    2014-03-01

    Forensic scientists are currently investigating how to transition from capillary electrophoresis (CE) to massive parallel sequencing (MPS) for analysis of forensic DNA profiles. MPS offers several advantages over CE such as virtually unlimited multiplexy of loci, combining both short tandem repeat (STR) and single nucleotide polymorphism (SNP) loci, small amplicons without constraints of size separation, more discrimination power, deep mixture resolution and sample multiplexing. We present our bioinformatic framework My-Forensic-Loci-queries (MyFLq) for analysis of MPS forensic data. For allele calling, the framework uses a MySQL reference allele database with automatically determined regions of interest (ROIs) by a generic maximal flanking algorithm which makes it possible to use any STR or SNP forensic locus. Python scripts were designed to automatically make allele calls starting from raw MPS data. We also present a method to assess the usefulness and overall performance of a forensic locus with respect to MPS, as well as methods to estimate whether an unknown allele, which sequence is not present in the MySQL database, is in fact a new allele or a sequencing error. The MyFLq framework was applied to an Illumina MiSeq dataset of a forensic Illumina amplicon library, generated from multilocus STR polymerase chain reaction (PCR) on both single contributor samples and multiple person DNA mixtures. Although the multilocus PCR was not yet optimized for MPS in terms of amplicon length or locus selection, the results show excellent results for most loci. The results show a high signal-to-noise ratio, correct allele calls, and a low limit of detection for minor DNA contributors in mixed DNA samples. Technically, forensic MPS affords great promise for routine implementation in forensic genomics. The method is also applicable to adjacent disciplines such as molecular autopsy in legal medicine and in mitochondrial DNA research. PMID:24528572

  7. Microanalytical Methods for Bio-Forensics Investigations

    2006-02-10

    Forensics investigations of bio-crime or bio-terrorism incidents require careful analysis of collected evidentiary material. Although the biological markers in the evidentiary material are important (e.g. genomic signatures, protein markers), the elemental make-up of the organisms themselves and the surrounding non-biological material is extremely useful for attributing a specific process and, perhaps, specific persons to the production of the biological agent. This talk will describe the coordinated use of microanalytical techniques such as SEM-EDX, STEM-EDX, and NanoSIMS for generating compositional signatures for bio-forensics investigations. These analytical techniques span length scales from the 50 {micro}m range to the 5nm range. The range of analytical sensitivities spans from {approx}.5wt% for EDX down to parts per billion for SIMS techniques. In addition, we will discuss the use of spectrum imaging techniques for rapidly extracting the key elemental signatures from large scale data sets. Spectrum imaging techniques combined with multivariate statistical analysis allow for the collection and interrogation or enormous quantities of data without pre-biasing the answer.[1] Spectrum imaging has been used successfully in EDX microanalysis[1] (both in the SEM and TEM) and TOF-SIMS[2]. In this study, a set of test biological agents, ?-irradiated Bacillus thuringiensis (Bt), were examined using the aforementioned microanalytical techniques. The sample set included a number of processing conditions to gauge the ability of these techniques to identify the production methods of these simulated agents. Complementary but distinct forensic signatures were obtained by all three analytical techniques. Figure 1 shows two types of silicate particles observed among the spore material itself. At this length scale, the spores themselves cannot be resolved, but the presence of these silicates is key marker for distinguishing this production route. A STEM-EDX spectrum image from

    In this study we attempted to visualize certain irregularities that took place in the evaluation of a patient with personality disorders performed by psychiatrist expert witness, which resulted in an incorrect diagnosis, leading to wrong ruling of the court and a referral of the patient to clinical therapy lasting six years. The psychiatric and psychological expert opinions submitted to the court and first-hand psychiatric and psychological examination of the patient were analyzed. Efforts were made to show that the failure to comply with the diagnostic criteria in the process of diagnosis and not taking into account the previously issued five forensic psychiatric opinions issued by independent and experienced teams of psychiatrist expert witnesses, as well as not taking into account the nature of the offense committed have led to a number of irregularities in the assessment of the mental state of the patient. Above mentioned shortcomings have caused unjustified legal classification of the offense and six years long detention of the patient in closed psychiatric institutions, in our regard unnecessary. The described case could be regarded as an abuse of psychiatry for the non-medical purposes and thus should have be punish. Based on the presented case it has been demonstrated that insufficient experience in forensic psychiatry and failure to comply with diagnostic criteria of psychiatrists and psychologists expert witnesses had led to a series of blatant offense of civil rights and liberties, and thus unnecessary detention of the patient for six years.

    Given the continuing advances in gait biometrics, it appears prudent to investigate the translation of these techniques for forensic use. We address the question as to the confidence that might be given between any two such measurements. We use the locations of ankle, knee, and hip to derive a measure of the match between walking subjects in image sequences. The Instantaneous Posture Match algorithm, using Harr templates, kinematics, and anthropomorphic knowledge is used to determine their location. This is demonstrated using real CCTV recorded at Gatwick International Airport, laboratory images from the multiview CASIA-B data set, and an example of real scene of crime video. To access the measurement confidence, we study the mean intra- and inter-match scores as a function of database size. These measures converge to constant and separate values, indicating that the match measure derived from individual comparisons is considerably smaller than the average match measure from a population.

    In the past century, forensic investigators have universally accepted fingerprinting as a reliable identification method, which relies mainly on pictorial comparisons. Despite developments to software systems in order to increase the probability and speed of identification, there has been limited success in the efforts that have been made to move away from the discipline's absolute dependence on the existence of a prerecorded matching fingerprint. Here, we have revealed that an information-rich latent fingerprint has not been used to its full potential. In our approach, the content present in the sweat left behind-namely the amino acids-can be used to determine physical such as gender of the originator. As a result, we were able to focus on the biochemical content in the fingerprint using a biocatalytic assay, coupled with a specially designed extraction protocol, for determining gender rather than focusing solely on the physical image.

    At the forensic autopsy of a sexual murder victim, some trace hairs, possibly belonging to the perpetrator, were saved. Initially, the analysis of a pubic hair shaft only revealed the presence of the mitochondrial (mt) DNA haplotype profile consisting of the (CA)(6) allele and the complete hypervariable region 1 (HV1) and 2 (HV2) sequence. Later, typing of some further telogene trace hairs, which had been stored for several years, yielded a nuclear short tandem repeat (STR) profile. We used both the mtDNA haplotype and the STR profile to start a DNA mass screening project involving 2,335 male citizens of the relevant communities. MtDNA screening was carried out by using the CA repeat amplification in combination with an SNP typing procedure based on the restriction site analysis of amplified d-loop sequences. The aim of our paper is to put mass screening with mtDNA up for discussion. PMID:16583247

    Conventional methods of gathering forensic evidence at crime scenes are encumbered by difficulties that limit local law enforcement efforts to apprehend offenders and bring them to justice. Working with a local law-enforcement agency, Sandia National Laboratories has developed a prototype multispectral imaging system that can speed up the investigative search task and provide additional and more accurate evidence. The system, called the Criminalistics Light-imaging Unit (CLU), has demonstrated the capabilities of locating fluorescing evidence at crime scenes under normal lighting conditions and of imaging other types of evidence, such as untreated fingerprints, by direct white-light reflectance. CLU employs state of the art technology that provides for viewing and recording of the entire search process on videotape. This report describes the work performed by Sandia to design, build, evaluate, and commercialize CLU.

    Turner's syndrome, the most common sex chromosome disorder of females, is caused by complete or partial loss of one X chromosome and is associated with a wide range of internal and external manifestations and increased mortality rates (three to nine times the background population). While individuals with Turner's syndrome may survive for many decades, premature and unexpected deaths can occur that bring decedents to the attention of forensic examiners. Causes of death in Turner's syndrome are often linked to underlying cardiovascular conditions such as aortic dissection, congenital cardiovascular disease, ischemic heart, and cerebrovascular disease, but deaths due to noncardiac causes also occur with increased frequency. The latter include epilepsy, diabetes mellitus, chronic renal disease, pneumonia, chronic liver disease, and malignancy. Thus, the autopsy evaluation of these cases requires careful examination of all major organ systems, with the consideration of confirmatory cytogenetic testing. PMID:24313855

    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. PMID:26174557

    The forensic pathologists have a challenging task during the ascertainment of the manner of death in cut throat injuries when presented with no proper history or witnesses. We report a rare homicide, where a person was killed by the father of his gay partner. A 51-year-old married man was found dead in his car on the driving seat at a road. There were blood stains on the dash board and windscreen. No weapon had been recovered. At autopsy, a deep, oblique, long incised injury was found on the front of the neck. There were no hesitant or defense injuries. The cause of death was cut throat. The findings were compatible with a homicidal cut throat by a right handed person from behind after head being restrained firmly. Findings were compatible with the history provided by the suspect.

    Pseudologia fantastica, also known as mythomania, or pathological lying, is a psychiatric phenomenon that is a mixture of fact and fiction involving fantasized events and self aggrandizing personal roles. It has been recognized in the field for over a century. In this case report we discuss three different cases, two of them presented in the acute inpatient setting and one outpatient setting. All three presented with the common theme of extensive and 'pathological lying' in a manner that was notably very destructive to them and posing significant challenges to the treatment team. In an attempt to shed light into some of the clinical and legal/forensic challenges it creates when faced in the clinical settings, we also raise the need for a better definition and classification of this symptom in the DSM.

    There are few other specialties in psychiatry where the cultural nature and social norms of a society has more impact than the specialty of forensic psychiatry. In the Muslim and Arab worlds, Islamic principles govern the foundation of thoughts required to make laws. Those necessarily include legal issues in psychiatry. The impact of these matters on individuals as patients and the community at large can not be overestimated. Those issues will include laws of involuntary hospitalization and evaluation of mental competence toward different life functions such as commercial interaction, writing a will, marriage, divorce, and child custody. Islamic law has a definite position on criminal responsibility as well as other vital matters such as compensation of damages, including medical malpractice. This article discusses problems and peculiarities involved in the canonization of these laws in islamic communities, considering different arguments presented from one point of view versus another.

    For the past two years, the Isotope Sciences Division (formerly Nuclear Chemistry) has been developing a program to extract forensic information from samples of plutonium or highly-enriched uranium. In the case of Pu, it is possible to determine the date of chemical separation, the date of its casting as metal, the enrichment of the uranium starting material, the length and perhaps other details (neutron spectrum and fluence) of reactor irradiation, the reprocessing technique, and clues to the identity of a specific facility. For enriched uranium, information is possible on the detailed timeline of material production, including the date of enrichment, whether the plant feed was formerly-irradiated uranium, the date of final purification, and facility-specific clues.

    The forensic odontologist has assumed a more visible role in the last decade, having been called upon repeatedly to assist both law enforcement agencies and the judicial system. It has become quite common for dentists to establish the identity of unknown bodies; to quickly and positively identify the victims of mass disasters such as airliner crashes, floods, and earthquakes; as well as to provide testimony in court concerning bite marks or other matters that require dental expertise. Litigation directed at dental defendants for failure to diagnose, properly treat, or obtain valid consent from plaintiff patients is also on the rise. In each of these fields, dentists who have been specially trained in or who have devoted their practices to the dental diagnostic sciences have been looked to widely as experts. This article discusses in detail these areas and others that affect the dental diagnostician. PMID:8416822

    2002-12-01

    Forensic seismology was first termed by H.I.S. Thirlaway in the late 1950s to describe what is now known as verification seismology. In nuclear monitoring it is often the study of anomalous events that for some reason caused an operational system to break down. Examples of events that have elicited study include abnormal mining explosions, mine collapse and rockbursts, earthquakes near nuclear test sites and anomalous nuclear explosions. Analysis of these anomalous disturbances has been the key to understanding source physics. This information in turn, has improved our understanding of the physical basis of seismic event identification, yield estimation, and evasion scenarios. In this talk, we will review examples of anomalous disturbances from different types of sources and how the subsequent analysis led to an improved understanding the effect of source phenomenology on nuclear explosion monitoring.

    Traumatic brain injury constitutes a significant proportion of cases requiring forensic examination, and it encompasses (1) blunt, nonmissile head injury, especially involving motor vehicle accidents, and (2) penetrating, missile injury produced by a range of high- and lower-velocity projectiles. This review examines the complex pathophysiology and biomechanics of both types of neurotrauma and assesses the macroscopic and histologic features of component lesions, which may be used to determine the cause and manner of death resulting from an intentional assault or accident. Estimation of the survival time postinjury by pathologic examination is also important where malicious head injury is suspected, in an attempt to ascertain a time at which the traumatic event might have been committed, thereby evaluating the authenticity of statements made by the alleged perpetrator.

    Dengue virus is a single-stranded RNA virus that is a member of the family Flaviviridae, genus Flavivirus. It is usually transmitted by the female Aedes aegypti mosquito. Dengue fever is a febrile illness caused by 1 of 4 serotypes of the virus, which may progress to dengue hemorrhagic fever or dengue shock syndrome. The mortality rate of untreated dengue shock syndrome is more than 20%. The reported incidence has increased 30-fold for the past 50 years with an estimated 50 to 100 million dengue infections globally each year, which includes 22,000 deaths. Because of this rapid increase in numbers, more cases will be seen in forensic mortuaries, with diagnostic problems arising from nonspecific or unusual manifestations. In this review, the clinicopathological features of dengue viral infection are evaluated. Adequate blood and tissue sampling at the time of autopsy is mandatory for successful microbiological identification and characterization. PMID:27093563

    Three cases of cremation on open-air pyres are described. One was classified as a suicide and two as homicides. Fire duration was estimated at approximately 1 h, close to 2 h and more than 3 h, respectively. The position of the remains, the colour alteration of bone and the burned bone fractures biomechanics are discussed. Knowledge of normal burn patterns in fire and detection of perimortem lesions are essential. These three cases highlight the specific thermal alterations and burning processes in accordance with fire duration. In each case, careful investigation yielded clues as to the manner of death. Close cooperation between law enforcement and forensic pathology investigators is required in order to correctly identify the circumstances of death. PMID:24949561

    Fighting movie piracy often requires automatic content identification. The most common technique to achieve this uses watermarking, but not all copyrighted content is watermarked. Video fingerprinting is an efficient alternative solution to identify content, to manage multimedia files in UGC sites or P2P networks and to register pirated copies with master content. When registering by matching copy fingerprints with master ones, a model of distortion can be estimated. In case of in-theater piracy, the model of geometric distortion allows the estimation of the capture location. A step even further is to determine, from passive image analysis only, whether different pirated versions were captured with the same camcorder. In this paper we present three such fingerprinting-based forensic applications: UGC filtering, estimation of capture location and source identification.

    Identification plays a major role in any crime investigation. The pattern of wrinkles on the lips has individual characteristics like fingerprints. Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. In the past decades, lip-print studies attracted the attention of many scientists as a new tool for human identification in both civil and criminal issues. The lip crease pattern is on the vermilion border of the lip, which is quite mobile and lip prints may vary in appearance according to the pressure, direction and method used in making the print. It concludes by enlightening the readers with the fact that the possibilities to use the red part of lips to identify a human being are wider than it is commonly thought. PMID:23946586

    The objectives of this study were to describe the disposition and housing trajectories of individuals found Not Criminally Responsible on account of Mental Disorder (NCRMD), and the factors that predict different trajectories. To do so, disposition and housing status were coded for 934 NCRMD patients over a 36-month follow-up period. Sequential data analysis resulted in four distinct trajectories: detention in hospital, conditional discharge in supportive housing, conditional discharge in independent housing, and absolute discharge to unknown housing. The likelihood of a placement in supportive housing compared with detention significantly decreased for individuals with a higher index offense severity. Less restrictive trajectories were significantly predicted by clinical factors. The results revealed little change in the disposition and housing trajectories of NCRMD patients. Furthermore, decisions about disposition and housing placement reflect a knowledge-practice gap between risk factors known to be predictive of community resources use in the forensic population.

    The dismemberment of a corpse is fairly rare in forensic medicine. It is usually performed with different types of sharp tools and used as a method of concealing the body and thus erasing proof of murder. In this context, the disarticulation of body parts is an even rarer event. The authors present the analysis of six dismemberment cases (well-preserved corpses or skeletonized remains with clear signs of dismemberment), arising from different contexts and in which different types of sharp tools were used. Two cases in particular showed peculiar features where separation of the forearms and limbs from the rest of the body was performed not by cutting through bones but through a meticulous disarticulation. The importance of a thorough anthropological investigation is thus highlighted, since it provides crucial information on the manner of dismemberment/disarticulation, the types of tools used and the general context in which the crime was perpetrated.

    The recent advances in DNA profiling have made DNA evidence to be more widely accepted in courts. This has revolutionized the aspect of forensic odontology. DNA profiling/DNA fingerprinting has come a long way from the conventional fingerprints. DNA that is responsible for all the cell's activities, yields valuable information both in the healthy and diseased individuals. When other means of traditional identification become impossible following mass calamities or fire explosions, teeth provide a rich source of DNA as they have a high chemical as well as physical resistance. The recent evolution in the isolation of DNA and the ways of running a DNA fingerprint are highlighted in this literature review. PMID:26015692

    2016-09-01

    Localized thermal injuries in animals may be caused by exposure to fire and radiant heat, contact with hot items including hot liquids or steam, inhalation of hot air, and exposure to cold temperatures. In addition, animal fire victims may have intoxications caused by smoke gas. This article reviews the causes, pathogenetic aspects, morphological findings, additional investigations, differential diagnoses, and causes of death in various forms of thermal injuries. Since these cases do not occur frequently in diagnostic pathology, they represent a challenging task in general but also with respect to forensic or criminal aspects, such as whether a lesion represents an accidental or nonaccidental effect. Besides detailed information about the circumstances at the location, thermal injuries in animals require a thorough morphological evaluation, including additional investigations in conjunction with a profound knowledge about the possible lesion spectrum and suitable additional investigations.

    2016-09-01

    The diagnosis of anaphylaxis in a pre- or post-mortal phase involves the formulation of problems not yet solved by the international scientific literature, due to the complexity of pathogenic factors and pathophysiological processes that characterizes it. For forensic autopsies, further problems of differential diagnosis arise and often leave the forensic pathologist unable to express an opinion of certainty, as a result of lack of case history, circumstantial and autoptical-histopathological data. Nevertheless, in routine cases the postmortem diagnosis of anaphylactic death continues to be based on exclusion and circumstantial evidence. The author, after an extensive review of the literature relating to deaths from anaphylaxis of forensic pathological interest, and a discussion of the microscopical and biochemical findings, proposes a diagnostic protocol for forensic purposes and evaluates the diagnostic perspectives enabled by the newly available analytic techniques and markers. Maybe, the application of omics methodologies could help in the future for anaphylaxis diagnosis. PMID:27591544

    Forensic image analysis is required an expertise to interpret the content of an image or the image itself in legal matters. Major sub-disciplines of forensic image analysis with law enforcement applications include photo-grammetry, photographic comparison, content analysis and image authentication. It has wide applications in forensic science range from documenting crime scenes to enhancing faint or indistinct patterns such as partial fingerprints. The process of forensic image analysis can involve several different tasks, regardless of the type of image analysis performed. Through this paper authors have tried to explain these tasks, which are described in to three categories: Image Compression, Image Enhancement & Restoration and Measurement Extraction. With the help of examples like signature comparison, counterfeit currency comparison and foot-wear sole impression using the software Canvas and Corel Draw.

    This mixed-method study used administrative data from 68 supportive housing programs and evaluative and qualitative site visit data from a subset of four forensic programs to (a) compare fidelity to the Housing First model and residential client outcomes between forensic and nonforensic programs and (b) investigate whether and how providers working in forensic programs can navigate competing Housing First principles and criminal justice mandates. Quantitative findings suggested that forensic programs were less likely to follow a harm reduction approach to substance use and clients in those programs were more likely to live in congregate settings. Qualitative findings suggested that an interplay of court involvement, limited resources, and risk environments influenced staff decisions regarding housing and treatment. Existing mental health and criminal justice collaborations necessitate adaptation to the Housing First model to accommodate client needs. PMID:26438288

    When assisting the courts in criminal proceedings, the work of forensic physicians are leaning more towards the preparation of written evidence rather than the giving of oral evidence in person. For this, they may be asked to serve either as professional witnesses or expert witnesses. These 2 roles have nevertheless been a constant source of confusion among forensic physicians. In view of this, the article aims to highlight the similarities and differences between these 2 roles particularly in relation to the preparation of written evidence. It will take a close look at the forms of written evidence which forensic physicians are expected to produce in those distinct capacities and the attending duties, evidentiary rules and legal liabilities. Through this, the work aspires to assist forensic physicians undertake those responsibilities on a more informed footing. PMID:24485431

    For a good performance in Clinical and Forensic Toxicology it is important to be aware of the biological and non-biological signs and symptoms related to xenobiotic exposure. This manuscript highlights and analyzes clinical and forensic imaging related to opioids abuse critically. Particularly, respiratory depression, track marks and hemorrhages, skin "popping", practices of phlebotomy, tissue necrosis and ulceration, dermatitis, tongue hyperpigmentation, "coma blisters", intra-arterial administration, candidiasis, wounds associated with anthrax or clostridium contaminated heroin, desomorphine related lesions and characteristic non-biological evidences are some commonly reported findings in opioids abuse, which will be discussed. For this purpose, clinical and forensic cases from our database (National Institute of Legal Medicine and Forensic Sciences, North Branch, Portugal), in addition to literature data, are reviewed.

    Hyperspectral imaging (HSI) integrates conventional imaging and spectroscopy, to obtain both spatial and spectral information from a specimen. This technique enables investigators to analyze the chemical composition of traces and simultaneously visualize their spatial distribution. HSI offers significant potential for the detection, visualization, identification and age estimation of forensic traces. The rapid, non-destructive and non-contact features of HSI mark its suitability as an analytical tool for forensic science. This paper provides an overview of the principles, instrumentation and analytical techniques involved in hyperspectral imaging. We describe recent advances in HSI technology motivating forensic science applications, e.g. the development of portable and fast image acquisition systems. Reported forensic science applications are reviewed. Challenges are addressed, such as the analysis of traces on backgrounds encountered in casework, concluded by a summary of possible future applications. PMID:23088824

    Nuclear forensics is important to our national security. Actions, including provision of appropriate funding, are needed now to sustain and improve the nation's nuclear forensics capabilities. The Department of Homeland Security (DHS), working with cooperating agencies and national laboratories, should plan and implement a sustainable, effective nuclear forensics program. Nuclear forensics is the examination and evaluation of discovered or seized nuclear materials and devices or, in cases of nuclear explosions or radiological dispersals, of detonation signals and post-detonation debris. Nuclear forensic evidence helps law enforcement and intelligence agencies work toward preventing, mitigating, and attributing a nuclear or radiological incident. This report, requested by DHS, the National Nuclear Security Administration, and the Department of Defense, makes recommendations on how to sustain and improve U.S. nuclear forensics capabilities. The United States has developed a nuclear forensics capability that has been demonstrated in real-world incidents of interdicted materials and in exercises of actions required after a nuclear detonation. The committee, however, has concerns about the program and finds that without strong leadership, careful planning, and additional funds, these capabilities will decline. Major areas of concern include: Organization. The responsibility for nuclear forensics is shared by several agencies without central authority and with no consensus on strategic requirements to guide the program. This organizational complexity hampers the program and could prove to be a major hindrance operationally. Sustainability. The nation's current nuclear forensics capabilities are available primarily because the system of laboratories, equipment, and personnel upon which they depend was developed and funded by the nuclear weapons program. However, the weapons program's funds are declining. Workforce and Infrastructure. Personnel skilled in nuclear forensics

    Abstract: As in many domains, there is increasing agreement in the user and research community that digital forensics analysts would benefit from the extension, development and application of advanced techniques in performing large scale and heterogeneous data analysis. Modern digital forensics analysis of cyber-crimes and cyber-enabled crimes often requires scrutiny of massive amounts of data. For example, a case involving network compromise across multiple enterprises might require forensic analysis of numerous sets of network logs and computer hard drives, potentially involving 100?s of gigabytes of heterogeneous data, or even terabytes or petabytes of data. Also, the goal for forensic analysis is to not only determine whether the illicit activity being considered is taking place, but also to identify the source of the activity and the full extent of the compromise or impact on the local network. Even after this analysis, there remains the challenge of using the results in subsequent criminal and civil processes.

    Supercritical fluid technology is a rapidly expanding analytical technique. Here we give a brief insight into the background of supercritical fluid technology and how supercritical fluid extraction and supercritical fluid chromatography work in analysis. The applications of these two techniques in forensic science are known to be important. The main area of forensic use of supercritical fluid technology is in the sample preparation and separation of drugs of abuse particularly opiates, cannabinoids, cocaine and sedatives. Supercritical fluid technology can be used for both time-of-death-related drug analysis and for obtaining information relating to long term drug abuse. We also give a review of the use of supercritical fluids in two other major forensic areas, fingerprinting and the extraction and separation of explosives from both bombing events and gunshot residues. Overall we show that supercritical fluid technology is fast becoming a major part of forensic investigations and that it is an invaluable analysis technique. PMID:10869681

    The aim of this qualitative study was to explore perspectives on rehabilitation of those detained in a New Zealand forensic hospital setting. Twenty forensic service users participated in individual interviews, which were audio-taped, transcribed verbatim, and subjected to thematic analysis. The analysis identified seven themes that were broadly categorized into those that concerned the rehabilitation context (external) and those that more directly reflected the forensic service user's personal experience (internal). External themes highlighted a person-centered approach, the nature of relationships with staff, consistency of care, and awareness of the rehabilitation pathway. Internal themes related to forensic service users' self-evaluations, agency, and coping strategies. These findings are discussed within the broader context in which rehabilitation took place.

    The forensic psychiatrist must be able to perform a credible psychiatric evaluation and render a competent psychiatric opinion in hotly contested multiple chemical sensitivity (MCS) litigation. Forensic psychiatrists are often requested to evaluate MCS claimants by third party payers, employers, lawyers, and government agencies regarding health care costs and disability payments, workers' compensation claims, unemployment benefits, workplace accommodation reimbursements for special housing and environmental needs, civil litigation, and other claims. The credible forensic psychiatric evaluation of MCS litigants is described using the multiaxial diagnostic system of DSM-IV. Forensic psychiatrists must avoid becoming polarized by the current MCS controversy. The ethical requirements of honesty and striving for objectivity can be met by keeping separate the roles of therapist and expert, staying abreast of the scientific literature regarding MCS, and understanding the role of the psychiatric expert in MCS litigation.

    2012-01-01

    In the last few years, Deoxyribonucleic Acid (DNA) analysis methods have been applied to forensic cases. Forensic dental record comparison has been used for human identification in cases where destruction of bodily tissues or prolonged exposure to the environment has made other means of identification impractical, that is, after fire exposure or mass disaster. Teeth play an important role in identification and criminology, due to their unique characteristics and relatively high degree of physical and chemical resistance. The use of a DNA profile test in forensic dentistry offers a new perspective in human identification. The DNA is responsible for storing all the genetic material and is unique to each individual. The currently available DNA tests have high reliability and are accepted as legal proofs in courts. This article gives an overview of the evolution of DNA technology in the last few years, highlighting its importance in cases of forensic investigation. PMID:23087582

    The Forensic Science Education Programs Accreditation Commission (FEPAC) requires accredited programs offer a "coherent curriculum" to ensure each student gains a "thorough grounding of the natural…sciences." Part of this curriculum includes completion of a minimum of 15 semester-hours forensic science coursework, nine of which can involve a class in forensic DNA biology. Departments that have obtained or are pursuing FEPAC accreditation can meet this requirement by offering a stand-alone forensic DNA biology course; however, materials necessary to instruct students are often homegrown and not standardized; in addition, until recently, the community lacked commercially available books, lab manuals, and teaching materials, and many of the best pedagogical resources were scattered across various peer-reviewed journals. The curriculum discussed below is an attempt to synthesize this disparate information, and although certainly not the only acceptable methodology, the below discussion represents "a way" for synthesizing and aggregating this information into a cohesive, comprehensive whole.

    Many forensic examiners are introduced to UNIX-based forensic utilities when faced with investigating a UNIX-like operating system for the first time. They will use these utilities for this very specific task, because in many cases these tools are the only ones for the given job. For example, at the time of this writing, given a FreeBSD 5.x file system, the author's only choice is to use The Coroner's Toolkit running on FreeBSD 5.x. However, many of the same tools examiners use for the occasional UNIX-like system investigation are extremely capable when a Windows system is the target. Indeed, the Linux operating system itself can prove to be an extremely useful forensics platform with very little use of specialized forensics utilities at all.

    Diogenes syndrome is a syndrome described in the clinical literature in elderly individuals characterized by social isolation and extreme squalor. A number of typical features are found in the forensic evaluation of these deaths as the cases usually initiate medicolegal investigations due to the circumstances and the lack of recorded medical histories. Examinations of the death scenes are often difficult as victim's houses are in a state of disrepair, with filth and clutter, and pet dogs may resent the intrusion of strangers. Bodies are often filthy, with parasitic infestations, and are often putrefied due to the social isolation of the deceased and the delay in the finding of the corpse. Bodies may be traumatized from postmortem animal depredation by rodents or pets (eg, cats, dogs), and injuries such as bruises and lacerations may be present from falls associated with terminal illnesses or alcoholism. Blood or putrefactive fluids may be spread throughout the house by pets. Treatable medical conditions are often present in advanced stages, and features of hypothermia may be found. Attending police may suspect robbery due to disarray of the house and homicide due to apparent "bleeding" around the body from purging of putrefactive fluids, injuries from falls, or postmortem animal activity and "blood stains" throughout the house from antemortem injuries and/or fluid spread by animals. Finally, the identification of the deceased may be compromised by decay and/or postmortem animal activity. Thus, in addition to having typical clinical manifestations, such individuals appear to form a distinct subset of forensic cases having characteristic death scene and autopsy features and presenting particular difficulties in postmortem evaluations.

    Because of the way computers operate, every discrete event potentially leaves a digital trace. These digital traces must be retrieved during a digital forensic investigation to prove or refute an alleged crime. Given resource constraints, it is not always feasible (or necessary) for law enforcement to retrieve all the related digital traces and to conduct comprehensive investigations. This paper attempts to address the issue by proposing a model for conducting swift, practical and cost-effective digital forensic investigations.

    The integrative approach to psychiatry has gained more importance in recent years. Is it justified or not, does it improve theory or practice, those are only some of the questions to which we are looking for answers, but in this paper we shall underline the necessity of enrolling forensic psychiatry into integrative, modern psychiatry. The reason and the motive for that integration is the fact that nowadays the content and the activities of contemporary forensic psychiatrists are totally reduced to executing the tasks given by courts. It is therefore entirely right to say that current forensic psychiatry finds itself in the passive role of executing orders of the court. Our aim is to point out how important it is that forensic psychiatry becomes an interdisciplinary profession in interaction with psychiatry but also with other medical branches just as with judiciary, educational institutions, moral-ethical institutions and religious institutions in producing preventive programmes and by participating in individual decision making process likewise. Our primary goal is to present the status and the position of contemporary forensic psychiatry and to specify the necessary improvements and its place in integrative psychiatry. It should be better, more meaningful and more ethical, both for the individual and the society in total. We want forensic psychiatry to include a protective and therapeutic role for each individual forensic examinee, i.e. a person who has already been in forensic examination and for whom one evaluates mental competence because of a mental disorder. We also want it to get a far larger and more active general role in society in terms of preventing criminal acts among the mentally ill and in society in total. PMID:18827777

    2014-01-01

    High throughput sequencing (HTS) generates large amounts of high quality sequence data for microbial genomics. The value of HTS for microbial forensics is the speed at which evidence can be collected and the power to characterize microbial-related evidence to solve biocrimes and bioterrorist events. As HTS technologies continue to improve, they provide increasingly powerful sets of tools to support the entire field of microbial forensics. Accurate, credible results allow analysis and interpretation, significantly influencing the course and/or focus of an investigation, and can impact the response of the government to an attack having individual, political, economic or military consequences. Interpretation of the results of microbial forensic analyses relies on understanding the performance and limitations of HTS methods, including analytical processes, assays and data interpretation. The utility of HTS must be defined carefully within established operating conditions and tolerances. Validation is essential in the development and implementation of microbial forensics methods used for formulating investigative leads attribution. HTS strategies vary, requiring guiding principles for HTS system validation. Three initial aspects of HTS, irrespective of chemistry, instrumentation or software are: 1) sample preparation, 2) sequencing, and 3) data analysis. Criteria that should be considered for HTS validation for microbial forensics are presented here. Validation should be defined in terms of specific application and the criteria described here comprise a foundation for investigators to establish, validate and implement HTS as a tool in microbial forensics, enhancing public safety and national security.

    Drs. Simopoulos and Cohen argue that knowledge of one's unconscious processes improves the forensic psychiatrist's capacity to manage complex forensic situations and to generate forensic formulations and opinions that are demonstrably more valid and reliable, much like competence in cultural assessment and formulation. In practice, the challenges posed by the application of these principles in forensic settings are far outweighed by the potential benefit. Forensic practice is informed by many specialties. Forensic psychiatrists do not have to complete full training in these disciplines to make use of the knowledge and perspectives they offer. The same may not be true of psychodynamic assessment and formulation. Although much can be learned from supervision, case seminars, conferences, and reading, such knowledge does little to foster awareness of one's unconscious processes that by definition operate outside awareness and thus contribute to the vitiating effect of bias. To date, the only method whereby psychiatrists can effectively come to appreciate their own unconscious processes in action is arguably through their own analysis conducted in the course of training in analysis or psychodynamic psychotherapy.

    Nuclear forensics and nuclear attribution have become increasingly important tools in the fight against illegal trafficking in nuclear and radiological materials. This technical report documents the field of nuclear forensics and nuclear attribution in a comprehensive manner, summarizing tools and procedures that have heretofore been described independently in the scientific literature. This report also provides national policy-makers, decision-makers, and technical managers with guidance for responding to incidents involving the interdiction of nuclear and radiological materials. However, due to the significant capital costs of the equipment and the specialized expertise of the personnel, work in the field of nuclear forensics has been restricted so far to a handful of national and international laboratories. In fact, there are a limited number of specialists who have experience working with interdicted nuclear materials and affiliated evidence. Most of the laboratories that have the requisite equipment, personnel, and experience to perform nuclear forensic analysis are participants in the Nuclear Smuggling International Technical Working Group or ITWG (see Section 1.8). Consequently, there is a need to disseminate information on an appropriate response to incidents of nuclear smuggling, including a comprehensive approach to gathering evidence that meets appropriate legal standards and to developing insights into the source and routes of nuclear and radiological contraband. Appendix A presents a ''Menu of Options'' for other Member States to request assistance from the ITWG Nuclear Forensics Laboratories (INFL) on nuclear forensic cases.

    One of the main threats for armed forces in conflict areas are attacks by improvised explosive devices (IED). After an IED attack a forensic investigation of the site is undertaken. In many ways military forensic work is similar to the civilian counterpart. There are the same needs to acquire evidence in the crime scene, such as fingerprints, DNA, and samples of the remains of the IED. Photos have to be taken and the geometry of the location shall be measured, preferably in 3D. A main difference between the military and the civilian forensic work is the time slot available for the scene investigation. The military must work under the threat of fire assault, e.g. snipers. The short time slot puts great demands on the forensic team and the equipment they use. We have done performance measurements of the Mantis-Vision F5 sensor and evaluated the usefulness in military forensic applications. This paper will describe some applications and show possibilities and also limitations of using a handheld laser imaging sensor for military forensic investigations.

    2005-01-01

    As an official subspecialty of psychiatry, forensic psychiatry residency training must meet the requirements established by the Accreditation Council of Graduate Medical Education. Attendant to these requirements is the expectation that graduates demonstrate core competencies in general areas common to all medical training programs but delineated for each specialty. In forensic psychiatry, trainees must learn to move from the role of healer to objective evaluator on behalf of third parties, a task that differs from general medical care and treatment. Thus, it is important for educators to maintain awareness of the experience of trainees as they adapt to forensic psychiatry, while understanding core competency requirements. This article outlines stages of development of forensic psychiatry fellows as a model for characterizing learning objectives and for supervising trainees in forensic psychiatry fellowship programs. These stages of development include (1) transformation, (2) growth of confidence and adaptation, and (3) identification and realization. Training directors and trainees can utilize this theoretical framework as a basis on which to establish parameters for core competency attainment and supervisory and assessment methods for forensic psychiatry training.

    Age assessment in children and young adults is a relevant medicolegal issue due to the gradual increase of persons devoid of proper identification documents in European countries. Because of the illegal immigration and growing crime rates among children and adolescents, age estimation for forensic purposes is often required. The scientific research and the extensive experience of forensic experts in the last decades focused on the use of radiographic methods addressed to evaluate the degree of skeletal or dental development as the most accurate parameters to estimate the chronological age of children and adolescents. This paper analyzes the ethical issues related to age estimation procedures based on radiographic methods, showing how the ethical principles of beneficence, nonmalevolence, justice, and autonomy may be guaranteed during the execution of the age assessment in forensic practice. The procedure might be conducted in accordance with international guidelines and protocols, though they need a higher homogenization and standardization. A strong collaboration between various scientific societies of professionals (forensic odontologists, forensic pathologists, forensic anthropologist, radiologists, pediatricians, and psychologists), who have been involved in age estimation for years, is needed to reach this goal.

    In the third millennium where ethical, ethological and cultural evolution seem to be leading more and more towards an inter-species society, the issue of animal experimentation is a moral dilemma. Speaking from a self-interested human perspective, avoiding all animal testing where human disease and therapy are concerned may be very difficult or even impossible; such testing may not be so easily justifiable when suffering-or killing-of non human animals is inflicted for forensic research. In order to verify how forensic scientists are evolving in this ethical issue, we undertook a systematic review of the current literature. We investigated the frequency of animal experimentation in forensic studies in the past 15 years and trends in publication in the main forensic science journals. Types of species, lesions inflicted, manner of sedation or anesthesia and euthanasia were examined in a total of 404 articles reviewed, among which 279 (69.1%) concerned studies involving animals sacrificed exclusively for the sake of the experiment. Killing still frequently includes painful methods such as blunt trauma, electrocution, mechanical asphyxia, hypothermia, and even exsanguination; of all these animals, apparently only 60.8% were anesthetized. The most recent call for a severe reduction if not a total halt to the use of animals in forensic sciences was made by Bernard Knight in 1992. In fact the principle of reduction and replacement, frequently respected in clinical research, must be considered the basis for forensic science research needing animals. PMID:26216717

    This article discusses the phenomenon of "context effects" by reviewing the findings and practices of a range of scientific fields, including astronomy, physics, biology, medicine, and especially the relevant research and theory from psychology. Context information, such as expectations about what one is supposed to see or conclude, has been found to have a small but relentless impact on human perception, judgment, and decision-making. The article then considers the vulnerability of forensic science practice to context effects, and concludes by suggesting that forensic science adopt practices familiar in other fields of scientific work, in particular blind or double-blind testing and also the use of evidence line-ups.

  19. Mainstreaming culture in psychology.

    2012-11-01

    Despite the "awakening" to the importance of culture in psychology in America, international psychology has remained on the sidelines of psychological science. The author recounts her personal and professional experience in tandem with the stages of development in international/cross-cultural psychology. Based on her research in cross-cultural personality assessment, the author discusses the inadequacies of sole reliance on either the etic or the emic approach and points out the advantages of a combined emic-etic approach in bridging global and local human experiences in psychological science and practice. With the blurring of the boundaries between North American-European psychologies and psychology in the rest of the world, there is a need to mainstream culture in psychology's epistemological paradigm. Borrowing from the concept of gender mainstreaming that embraces both similarities and differences in promoting equal opportunities, the author discusses the parallel needs of acknowledging universals and specifics when mainstreaming culture in psychology. She calls for building a culturally informed universal knowledge base that should be incorporated in the psychology curriculum and textbooks. PMID:23163473

  20. Accuracy Rates of Sex Estimation by Forensic Anthropologists through Comparison with DNA Typing Results in Forensic Casework.

    A common task in forensic anthropology involves the estimation of the biological sex of a decedent by exploiting the sexual dimorphism between males and females. Estimation methods are often based on analysis of skeletal collections of known sex and most include a research-based accuracy rate. However, the accuracy rates of sex estimation methods in actual forensic casework have rarely been studied. This article uses sex determinations based on DNA results from 360 forensic cases to develop accuracy rates for sex estimations conducted by forensic anthropologists. The overall rate of correct sex estimation from these cases is 94.7% with increasing accuracy rates as more skeletal material is available for analysis and as the education level and certification of the examiner increases. Nine of 19 incorrect assessments resulted from cases in which one skeletal element was available, suggesting that the use of an "undetermined" result may be more appropriate for these cases.

    Forensic nursing is a new nursing specialty that provides forensic nursing service to domestic violence victims and offenders. Development of the role of forensic nurses has become urgent and necessary. The high rates of domestic violence and sexual assault in Taiwan suggest that forensic nurses have an important role to play in domestic healthcare. This article highlights the significance of forensic nursing in Taiwan in the future in terms of its origin, definitions, models, roles and functions, training and education, and previous studies. Through cooperation among academia, government, industry, and law enforcement agencies, it is expected that forensic nursing will be a positive and important area of expansion for professional nursing.

    Forensic practice fees, billing, and collection procedures are quite different from those in general psychiatry. Most forensic practices have far fewer "clients," and individual bills are usually larger. Collections are usually better (and less frequently discounted) in forensic practice, and resolving billing disputes is far more straightforward. Medicare, Medicaid, other insurance coverage, provider networks and agreements, procedure codes, and diagnosis-related groups (DRGs) are all largely irrelevant in forensic work (although sometimes important to direct clinical services in correctional psychiatry or forensic treatment clinics). An understanding of the practicalities and ethics of charging and billing for forensic services greatly simplifies practice management. PMID:22617086

    Cyber forensics has been in the popular mainstream for some time, and has matured into an information-technology capability that is very common among modern information security programs. The goal of cyber forensics is to support the elements of troubleshooting, monitoring, recovery, and the protection of sensitive data. Moreover, in the event of a crime being committed, cyber forensics is also the approach to collecting, analyzing, and archiving data as evidence in a court of law. Although scalable to many information technology domains, especially modern corporate architectures, cyber forensics can be challenging when being applied to non-traditional environments, which are not comprised of current information technologies or are designed with technologies that do not provide adequate data storage or audit capabilities. In addition, further complexity is introduced if the environments are designed using proprietary solutions and protocols, thus limiting the ease of which modern forensic methods can be utilized. The legacy nature and somewhat diverse or disparate component aspects of control systems environments can often prohibit the smooth translation of modern forensics analysis into the control systems domain. Compounded by a wide variety of proprietary technologies and protocols, as well as critical system technologies with no capability to store significant amounts of event information, the task of creating a ubiquitous and unified strategy for technical cyber forensics on a control systems device or computing resource is far from trivial. To date, no direction regarding cyber forensics as it relates to control systems has been produced other than what might be privately available from commercial vendors. Current materials have been designed to support event recreation (event-based), and although important, these requirements do not always satisfy the needs associated with incident response or forensics that are driven by cyber incidents. To address these

Since 1925, forensic medicine is part of the medical examination regulation. In times of the 3rd Reich (1933-1945), most of forensic pathologists were influenced by and involved in National Socialism. The special subject of forensic medicine was endangered by the absence of political neutral forensic pathologists. PMID:15364380

    In this paper, the importance of modern technology in forensic investigations is discussed. Recent technological developments are creating new possibilities to perform robust scientific measurements and studies outside the controlled laboratory environment. The benefits of real-time, on-site forensic investigations are manifold and such technology has the potential to strongly increase the speed and efficacy of the criminal justice system. However, such benefits are only realized when quality can be guaranteed at all times and findings can be used as forensic evidence in court. At the Netherlands Forensic Institute, innovation efforts are currently undertaken to develop integrated forensic platform solutions that allow for the forensic investigation of human biological traces, the chemical identification of illicit drugs and the study of large amounts of digital evidence. These platforms enable field investigations, yield robust and validated evidence and allow for forensic intelligence and targeted use of expert capacity at the forensic institutes. This technological revolution in forensic science could ultimately lead to a paradigm shift in which a new role of the forensic expert emerges as developer and custodian of integrated forensic platforms.

    2008-04-01

    This report was produced by a Working Group of the American Physical Society's Program on Public Affairs in conjunction with the American Association for the Advancement of Science Center for Science, Technology and Security Policy. The primary purpose of this report is to provide the Congress, U.S. government agencies and other institutions involved in nuclear forensics with a clear unclassified statement of the state of the art of nuclear forensics; an assessment of its potential for preventing and identifying unattributed nuclear attacks; and identification of the policies, resources and human talent to fulfill that potential. In the course of its work, the Working Group observed that nuclear forensics was an essential part of the overall nuclear attribution process, which aims at identifying the origin of unidentified nuclear weapon material and, in the event, an unidentified nuclear explosion. A credible nuclear attribution capability and in particular nuclear forensics capability could deter essential participants in the chain of actors needed to smuggle nuclear weapon material or carry out a nuclear terrorist act and could also encourage states to better secure such materials and weapons. The Working Group also noted that nuclear forensics result would take some time to obtain and that neither internal coordination, nor international arrangements, nor the state of qualified personnel and needed equipment were currently enough to minimize the time needed to reach reliable results in an emergency such as would be caused by a nuclear detonation or the intercept of a weapon-size quantity of material. The Working Group assesses international cooperation to be crucial for forensics to work, since the material would likely come from inadequately documented foreign sources. In addition, international participation, if properly managed, could enhance the credibility of the deterrent effect of attribution. Finally the Working Group notes that the U.S. forensics

    To the best of our knowledge, the present register is the only nationwide forensic psychiatric patient register in the world. The aim of this article is to describe the content of the Swedish National Forensic Psychiatric Register (SNFPR) for Swedish forensic patients for the year 2010. The subjects are individuals who, in connection with prosecution due to criminal acts, have been sentenced to compulsory forensic psychiatric treatment in Sweden. The results show that in 2010, 1476 Swedish forensic patients were assessed in the SNFPR; 1251 (85%) were males and 225 (15%) were females. Almost 60% of the patients had a diagnosis of schizophrenia, with a significantly higher frequency among males than females. As many as 70% of the patients had a previous history of outpatient psychiatric treatment before becoming a forensic psychiatric patient, with a mean age at first contact with psychiatric care of about 20 years old for both sexes. More than 63% of the patients had a history of addiction, with a higher proportion of males than females. Furthermore, as many as 38% of all patients committed crimes while under the influence of alcohol and/or illicit drugs. This was more often the case for men than for women. Both male and female patients were primarily sentenced for crimes related to life and death (e.g., murder, assault). However, there were more females than males in treatment for general dangerous crimes (e.g., arson), whereas men were more often prosecuted for crimes related to sex. In 2010, as many as 70% of all forensic patients in Sweden had a prior sentence for a criminal act, and males were prosecuted significantly more often than females. The most commonly prescribed pharmaceuticals for both genders were antipsychotics, although more women than men were prescribed other pharmaceuticals, such as antidepressants, antiepileptics, and anxiolytics. The result from the present study might give clinicians an opportunity to reflect upon and challenge their

    crimes are not covered by legislation. Scots law divides homicide into three classes: murder, culpable homicide (ie. murder under mitigating circumstances), and non-criminal homicide. The homicide rate is relatively low with approximately 60 murders and 40 culpable homicides each year for a population of 5.12 million. The commonest methods are stabbing/cutting (40%) and hitting/kicking (20%). Only 3% are by firearms. Organised forensic medicine began with the professorships in medical jurisprudence at Edinburgh in 1806 and at Glasgow in 1839. Today forensic pathology services are funded by the central government but are based in the universities of Edinburgh, Glasgow, Dundee, and Aberdeen.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:8116596

    Problems encountered regarding the examination in forensic pathology are variable, even if the field of interest in limited to trauma alone. The most important problem appears to be the establishment of a causal relationship between the trauma and the death of the victim. From the materials I have contributed concerning examinations in forensic medicine, the problems inherent in the examination of the victim of traumatic shock may be introduced. The results from animal studies, which have been attempted to provide an experimental background to support the observations, are also discussed. My personal opinions on several trial cases in which there was a disagreement of opinion regarding the examination results will also be expressed. 1. Distinguishing death due to traumatic shock from death due to disease In the "Yacht school" incident, children with emotional disturbances and youths with a history of misconduct were treated with training which included physical punishment. Autopsy findings were compared between a 13-year old boy who was concluded to have died of traumatic shock from numerous beatings and a 21-year old youth who died of hemorrhagic pneumonia. In my opinion, a causative role of injury in the death was found in both cases. 2. Shock due to tourniquet This autopsy case concerns a 23-year-old male who entered a yoga training center, was tightly bound with a rope and died on the 8th day. Histological examination revealed thrombus formation in the small blood vessels and leukocyte agglutination within the blood vessels of the alveolar wall, suggesting DIC. While these findings were thought to be almost indistinguishable from those found in traumatic shock, the background conditions, including hunger, dehydration and hypothermia cannot be neglected in the evaluation. 3. Child abuse In one incident, a mother and her lover beat a 25-month old girl every day until her death. The original examination concluded that the cause of death was traumatic shock due to

    A reliable method for the quantitative analysis of ethanol in microvolumes (50-100 μL) of blood became available in 1922, making it possible to investigate the absorption, distribution, metabolism, and excretion (ADME) of ethanol in healthy volunteers. The basic principles of ethanol pharmacokinetics were established in the 1930s, including the notion of zero-order elimination kinetics from blood and distribution of the absorbed dose into the total body water. The hepatic enzyme alcohol dehydrogenase (ADH) is primarily responsible for the oxidative metabolism of ethanol. This enzyme was purified and characterized in the early 1950s and shown to have a low Michaelis constant (km), being about ~0.1 g/L. Liver ADH is therefore saturated with substrate after the first couple of drinks and for all practical purposes the concentration-time (C-T) profiles of ethanol are a good approximation to zero-order kinetics. However, because of dose-dependent saturation kinetics, the entire postabsorptive declining part of the blood-alcohol concentration (BAC) curve looks more like a hockey stick rather than a straight line. A faster rate of ethanol elimination from blood in habituated individuals (alcoholics) is explained by participation of a high km microsomal enzyme (CYP2E1), which is inducible after a period of chronic heavy drinking. Owing to the combined influences of genetic and environmental factors, one expects a roughly threefold difference in elimination rates of ethanol from blood (0.1-0.3 g/L/h) between individuals. The volume of distribution (Vd) of ethanol, which depends on a person's age, gender, and proportion of fat to lean body mass, shows a twofold variation between individuals (0.4-0.8 L/kg). This forensic science review traces the development of forensic pharmacokinetics of ethanol from a historical perspective, followed by a discussion of important issues related to the disposition and fate of ethanol in the body, including (a) quantitative evaluation of

    A forensic capability to help identify perpetrators and exclude innocent people should be an integral part of a strategy against terrorist attacks. Exercises have been conducted to increase our preparedness and response capabilities to chemical, biological, radiological, and nuclear (CBRN) terrorist attacks. However, incorporating forensic components into these exercises has been deficient. CBRN investigations rely on forensic results, so the need to integrate a forensic component and forensics experts into comprehensive exercises is paramount. This article provides guidance for planning and executing exercises at local, state, federal, and international levels that test the effectiveness of forensic capabilities for CBRN threats. The guidelines presented here apply both to situations where forensics is only a component of a more general exercise and where forensics is the primary focus of the exercise. PMID:21142761
