Fatality management in mass casualty incidents

Medical involvement in mass casualty incidents requires proper planning and preparedness. In disaster situations, legal aspects concerning the dead add to the general problem of a lack of time, place and resources to maintain routine working conditions, and demand authority and competence. The aspects of planning the recovery of the dead, transportation and morgue facilities, establishment of cause of death, identification, and the final disposition of the dead are discussed. The implementation of forensic mass fatality teams is felt to be the right answer for a better planning and coordination.     

Adherence of forensic odontologists to the ABFO guidelines for victim evidence collection

Certifying boards for different professions have the duty to help establish standards and guidelines for methodologies routinely performed within the discipline. For forensic dentists, this responsibility is placed upon the American Board of Forensic Odontology (ABFO). The purpose of this study was to examine whether board certified and noncertified forensic odontologists adhere to the ABFO Guidelines outlined in the collection of victim bitemark evidence. A questionnaire was developed to assess the compliance and attitudes towards the typical evidence collected, the photographic documentation, and the handling of the bite site injury. The results indicate the majority of the respondents in both representative groups routinely follow the guidelines set forth by the ABFO. The lack of personally photographing the bite injury on a consistent basis is an area of concern for all examiners. The photographic evidence is an instrumental part of the investigation and often cannot be utilized due to improper procedures being followed. The film type utilized, bite site impression techniques, and excision of any tissue samples remain an individual choice and vary significantly among each forensic odontologist.     

The influence of forensic evidence on the case outcomes of homicide incidents

Objective

In spite of the growth of forensic science services little published research exists related to the impact of forensic evidence on criminal case outcomes. The present study focused on the influence of forensic evidence on the case processing of homicide incidents.

Materials and Methods

The study utilized a prospective analysis of official record data that followed homicide cases in five jurisdictions from the time of police incident report to final criminal disposition.

Results

The results showed that most homicides went unsolved (34.5% conviction rate). Only 55.5% of the 400 homicide incidents resulted in arrest of which 77% were referred to the district attorney. On the other hand, 94% of cases referred to the district attorney were charged. Cases were more likely to have arrests, referrals, and charges when witnesses provided information to the police. Suspects who knew their victims were more likely to be arrested and referred to the district attorney. Homicides committed with firearms were less likely to be cleared. The most noteworthy finding was that none of the forensic evidence variables significantly influenced criminal justice outcomes.

Conclusions

The study results suggest that forensic evidence is auxiliary and non-determinative for homicide cases.

Adherence of forensic odontologists to the ABFO bite mark guidelines for suspect evidence collection

Boards and associations within forensic science have long been accepted as vehicles for the development and dissemination of protocols and recommendations for practice. Recent controversies surrounding bite mark analyses have brought the methods and practices of forensic dentists to the attention of both the courts and the media. In the mid-eighties the American Board of Forensic Odontology developed guidelines for bite mark analysis in response to unfavorable commentaries on the discipline by legal observers. The purpose of this study is to examine the adherence of board certified and noncertified forensic dentists to the guidelines for collection of evidence from bite mark suspects. A questionnaire was employed during an American Academy of Forensic Sciences meeting. Results showed that, in general, when the odontologists collected evidence they did adhere to the guidelines, although collection of salivary samples was not common. Of concern is the large number of odontologists who do not collect their own evidence from suspects. Police officers or other individuals often perform this task and therefore the guidelines must be disseminated to these groups to ensure that the maximum yield is obtained from bite mark evidence. A review of the materials used to collect evidence is also included with details of applications in forensic science.     

The role of psychological testing in forensic assessment

Despite the apparent widespread use of psychological tests in evaluations performed by psychologists to assist legal decision makers, there has been little critical but balanced examination of the appropriate parameters for the forensic use of such tests. The following discussion examines the nature of legal decision making, and concludes that the primary legal criterion for the adminissibility of psychological testing isrelevance to the immediate legal issue or to some underlying psychological construct. Assuming thataccuracy is a more consistent concern for psychologists performing such evaluations, the criticisms of various commentators are discussed. Some criticisms appear appropriate and are incorporated into a set of proposed guidelines for the use of psychological tests in forensic contexts. Other criticisms appear misplaced, however, and the call for a whole sale ban on psychological testing in the forensic context is rejected.     

基因编辑技术对法医学鉴定的影响和挑战

近年来基因编辑技术发展突飞猛进,已经出现第三代CRISPR/Cas9基因编辑技术。世界各国的法律对人类胚胎基因干预性研究从严管理。基因编辑在人类胚胎层面开展研究,甚至会导致基因编辑婴儿出生,改变人类的基因顺序等信息也由可能走向现实,这对法医学同一认定、亲缘关系鉴定等造成负面影响。同时,犯罪分子也可能利用基因编辑技术改变自己的基因信息,从而避开犯罪基因信息库中的信息。这一生物遗传学技术的进步和实践应用趋势,应当引起法医学鉴定人员警惕,国家相关部门也应当加强监管。     

The impact of police charges in incidents of wife abuse

The present study addressed the impact of an urban police force laying criminal charges in cases of wife abuse. Follow-up data from battered women and from police officers were collected to identify the long-term consequences of this police policy that began in 1981, including any negative or unintended side effects. Results indicated that the policy resulted in a dramatic increase in police-laid charges (2500%), and a shift from the Family to the Criminal Division of Provincial Court. Based on interview data, victims did not decrease their requests for police service (a feared side effect) and reported a significantly higher level of satisfaction with police service in this area. A significant reduction in police calls and victim-reported violence was associated with police intervention, especially when charges were laid. Paradoxically, police officers' attitudes about the policy were more negative than the actual positive changes that they helped to produce. Considerations for future research and professional training are outlined.     

The role of mobile computed tomography in mass fatality incidents

Mobile multi-detector computed tomography (MDCT) scanners are potentially available to temporary mortuaries and can be operational within 20 min of arrival. We describe, to our knowledge, the first use of mobile MDCT for a mass fatality incident. A mobile MDCT scanner attended the disaster mortuary after a five vehicle road traffic incident. Five out of six bodies were successfully imaged by MDCT in c. 15 min per body. Subsequent full radiological analysis took c. 1 h per case. The results were compared to the autopsy examinations. We discuss the advantages and disadvantages of imaging with mobile MDCT in relation to mass fatality work, illustrating the body pathway process, and its role in the identification of the pathology, personal effects, and health and safety hazards. We propose that the adoption of a single modality of mobile MDCT could replace the current use of multiple radiological sources within a mass fatality mortuary.     

Personality identification based on the outcomes of mass casualty events

This study concerns the problem of personality identification based on the outcomes of mass casualty events. New organizational measures are proposed to optimize the work with cadaveric materials. Specifically, they envisage creation of four major working groups and organization of their cooperation along the following lines: collection and delivery of postmortem information, systematization of antemortal information, and functioning of the identification centre. DNA-technologies and computer-assisted data processing are shown to find the increasingly wider application for personality identification.     

The psychological impact of stalking on female undergraduates.

This study examined the psychological impact of stalking upon female undergraduates, a population previously determined to experience a surprising stalking prevalence rate. Despite common understanding that stalking has deleterious effects, there have been no previous efforts to systematically assess them with standardized measures. Thirty-six female stalking victims were compared with 43 females who had been harassed and 48 controls. Psychological impact was assessed with the Posttraumatic Stress Disorder Scale, the Symptom Checklist-90-R, and the Self-Report Interpersonal Trust Scale. Stalked subjects endorsed significantly more PTSD symptoms and with greater severity than the harassed or control subjects. Stalked subjects also had significantly higher scores on several subscales of the SCL-90, and had significantly higher positive symptom totals and distress indices.

Seasonal variation of seclusion incidents from violent and suicidal acts in forensic psychiatric patients

BackgroundA seasonal variation in violence and suicidal behaviour has been reported in several studies with partially congruent results. Most of forensic psychiatric patients have a history of severe violent behaviour that often continues in spite of regular treatment. In the forensic psychiatric hospital environment aggressive and suicidal acts are often sudden and unpredictable. For reasons of safety, rapid and intensive coercive measures, such as seclusion and restraint, are necessary in the treatment of such patients.ObjectiveTo examine whether these involuntary seclusions have a seasonal pattern, possibly similar than the reported seasonal variation in violence and suicidal behaviour. By investigating the possibility of a seasonal variation of seclusion incidents from violent and suicidal acts, it may become possible to improve the management of forensic psychiatric patients.MethodsThe hospital files of all secluded patients at Niuvanniemi Hospital from 1 January 1996 to 31 December 2002 were examined. In total, 385 patients (324 male and 61 female) were identified as being secluded at least once in 1930 different incidents (1476 from male and 454 from female patients). Seasonal decomposition and linear regression with dummy month variables were used to examine the possibility of annual variations for seclusions.ResultsThe seasonal variation of involuntary seclusion incidents was statistically significant. According to the linear regression model, most of the seclusion incidents, affecting many different patients, began in July and August, and were concentrated throughout the fall until November. The sum of all seclusion days was lowest in January and highest between July and November (difference + 31% to + 37%).ConclusionsThese findings are mainly in agreement with results from other studies on seasonal variation and violent behaviour. The allocation of staff for late summer and fall might enhance the management of forensic psychiatric patients, thus leading to possible decreases in seclusion incidents. The factors affecting violent, aggressive and suicidal behaviours are complex and more investigation is needed to understand, identify, intervene and effectively reduce such behaviours.

The impact of bullying and coping strategies on the psychological distress of young offenders

Abstract

This study investigated the involvement in bullying, the psychological distress, and the coping strategies of 99 males in an English young offenders institution. The Direct and Indirect Prisoner Behaviour Checklist (DIPC; Ireland, 1998 Ireland, J. L. 1998. Direct and Indirect Prisoner Behaviour Checklist (DIPC), Lancashire, , UK: University of Central Lancashire.  [Google Scholar]), the 21-item Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995 Lovibond, P. F. and Lovibond, S. H. 1995. The structure of negative emotional states: Comparison of the depression anxiety stress scales (DASS) with the Beck depression and anxiety inventories. Behaviour Research Therapy, 33: 335–343. [PubMed], [Web of Science ®] , [Google Scholar]) and the 48-item Coping Styles Questionnaire (CSQ; Roger et al., 1993 Roger, D., Jarvis, G. and Najarian, B. 1993. Detachment and coping: The construction and validation of a new scale for measuring coping strategies. Personality and Individual Differences, 15: 619–626. [Crossref], [Web of Science ®] , [Google Scholar]) were administered. Over 60% of prisoners were involved in bullying (as a victim or bully), as indicated by responses on the DIPC. Emotional and avoidance coping were significantly related to psychological distress. Bully/victims were significantly more depressed than prisoners not involved in bullying, and being a bully/victim was a significant predictor of higher stress scores. Significant correlations were observed between all psychological distress measures and the number of bullying behaviours experienced by prisoners. These findings are discussed in relation to their implications for prisoner care and avenues for future research are proposed.     

Child abduction murder: the impact of forensic evidence on solvability

This study examined 733 child abduction murders (CAMs) occurring from 1968 to 2002 to explore the influence of forensic evidence on case solvability in CAM investigations. It was hypothesized that the presence of forensic evidence connecting the offender to the crime would enhance case solvability in murder investigations of abducted children. This study examined the impact of CAM of different types of forensic evidence and the impact of the summed total of forensic evidence items on case solvability by controlling for victim age, victim race, victim gender, and victim-offender relationship. Time and distance theoretical predictors were also included. Binomial logistic regression models were used to determine whether forensic evidence was a critical solvability factor in murder investigations of abducted children. This research indicated that, while forensic evidence increased case solvability, the impact of forensic evidence on solvability was not as important as other solvability factors examined.     

The impact of Māori cultural values on forensic science practice in New Zealand

Forensic science aims to serve society by advancing justice. It is accepted that some actions taken by the state in the interests of advancing justice, such as postmortem examinations, may impinge on values held by members of groups within society. Such actions have the potential to cause cultural offense. It is important that forensic scientists are aware of these issues and that as a profession we should take actions, where possible, to reduce any potential offense and consequently reduce unnecessary distress. This paper examines the impact of these issues on forensic practice in New Zealand, and, in particular, in relation to the cultural values of Māori, the indigenous people of New Zealand. Interviews and workshops were used to identify forensic practices involving a risk of cultural offense. Particular issues were identified in regard to crime scene attendance and examination, postmortem attendance and sample storage, disposal, and return. This paper describes the response developed by the Institute of Environmental Science and Research Limited (ESR) to address these issues, including a cultural awareness training package and reference brochure.

The analysis of forensic samples using laser micro-pyrolysis gas chromatography mass spectrometry

Laser micropyrolysis gas chromatography-mass spectrometry is used for the analysis of paint, photocopier toner, and synthetic fiber materials to test the forensic potential of this emerging technology. It uses a laser microprobe to selectively target very small parts of the materials for GC-MS analysis. Whereas the paint and the toner samples were amenable to direct laser pyrolysis, the synthetic fibers proved transparent to the 1064 nm laser radiation. The difficulty with the fibers demonstrates that a specific laser wavelength may not be appropriate for all types of materials. Nevertheless, the fibers were able to be indirectly pyrolyzed by impregnation in a strongly absorbing graphite matrix. A vast array of hydrocarbon pyrolysates was detected from the different materials studied. Unique product distributions were detected from each sample and in sufficient detail to facilitate individual molecular characterization (i.e., molecular fingerprinting). The integrity of the laser data were confirmed by comparison to data obtained from the same samples by the more conventional pyroprobe pyrolysis GC-MS method. The high spatial resolution and selectivity of the laser method may be advantageous for specific forensic applications, however, further work may be required to improve the reproducibility of the data.
