Blunt force cranial trauma in the Cambodian killing fields

In this paper we present a unique pattern of blunt force cranial trauma that was observed in 10 of a sample of 85 crania from a Cambodian skeletal collection comprised of Khmer Rouge victims. Initial examination of the trauma, which presents as substantial damage to the occipital with fractures extending to the cranial base, suggested the pattern was classifiable as a basilar or ring fracture. However, further investigation, including trauma analysis and historical research, revealed that this fracture type is distinctive from basilar and ring fractures. Historical data indicate that a particular execution method was the likely source of the trauma. Recognition of this trauma pattern is significant because it exemplifies the distinct fracture configuration resulting from an apparently categorical and methodical execution technique. Identification of this fracture type could potentially assist forensic investigators in the recognition of specific methods of murder or execution.     

The review panel process: an algorithm for the conditional release of insanity acquittees

The release of insanity acquittees requires making informed decisions regarding both the presence and severity of an individuals' mental illness and the dangerousness of these individuals. This study evaluated the usefulness of employing structured assessments of mental health and violence risk factors in the conditional release decision-making process. All persons found Not Guilty by Reason of Insanity at East Louisiana Mental Health System, Forensic Division who underwent a review panel between July 1, 1997 and July 1, 1999 were included in this study. The Classification and Regression Tree analysis was utilized to arrive at cutpoints that would optimize the predictive ability of the decision tree analysis. The results indicated that the Community Outpatient Treatment Readiness Profile score was the strongest predictor -- all patients receiving a score of 62 or greater on this scale were recommended to remain at the facility. When women were recommended for release, it was to civil facilities and with moderate levels of symptoms. For males with moderate symptoms, low PCL-R scores were associated with recommendations for release, whereas high scores were associated with recommendations for continued commitment. Our data suggests that algorithms may be useful to governing bodies when making release decisions.     

A cluster analysis of people on Community Treatment Orders in Victoria, Australia

This paper explores the clinical, social and demographic characteristics of 164 people on Community Treatment Orders (CTOs) in one area mental health service in Victoria, Australia. The results of an exploratory cluster analysis are presented to address the question of whether people on Community Treatment Orders can be categorised into statistically reliable, qualitatively distinct groupings. The data are presented in the context of key stakeholder perspectives on the current use and purpose of CTOs. Three stable clusters emerged and each potentially reflects how social dimensions, as well as clinical issues, influence decision making regarding the implementation of CTOs. These findings are important in the context of policy and practice in Victoria, where the use of CTOs is common practice, and orders are generally made for a 12 month period. The potential for improved targeting of CTOs and more specific treatment planning is identified.     

Clothing damage analysis in alleged sexual assaults--the need for a systematic approach

Clothing damage analysis is an integral part of the examinations carried out in sexual assault type cases. This analysis can be used to corroborate different versions of events and is at its most powerful in elucidating false allegation cases and consent cases. The purpose of this study was to determine to what extent people with varying levels of forensic awareness, experience and training could correctly carry out damage analysis. Two participant groups were asked to take part in this study. Group A ('forensic group') comprised participants at a forensic science conference, and Group B ('student group') comprised students undertaking a degree course in Forensic Science. Each group was given a practical workshop consisting of a lecture outlining common fabric types and general features observed in different damage types. Each participant was subsequently shown 25 pieces of 'damage' and asked to identify both the type of fabric construction (knit or weave) and the type of damage (cut, tear, rip, wear and tear). The ability to identify fabric construction and damage types varied within the two groups studied and across the groups. The forensic group performed better both in fabric and damage assessment than the student group. This paper suggests a systematic approach to clothing damage analysis to maximise the benefits that can be obtained from this area of forensic science and to minimise the subjectivity within the field.     

The Impact of Child Abuse History, PTSD Symptoms, and Anger Arousal on Dating Violence Perpetration Among College Women

Preliminary research suggests that child abuse is indirectly associated with female-perpetrated intimate partner violence via posttraumatic stress disorder (PTSD) symptoms and anger. To date, however, no known studies have investigated these relationships for physical and psychological dating violence within a female college sample. Therefore, the purpose of the current study was to examine the impact of child abuse history, PTSD symptoms, and anger arousal on female-perpetrated physical and psychological dating violence. Female undergraduates (N = 496) completed measures of child abuse, PTSD symptoms, anger arousal, and dating violence perpetration as part of a larger trauma and violence study. Results indicated that child abuse directly predicted female-perpetrated physical and psychological dating violence and indirectly impacted female-perpetrated physical and psychological dating violence via PTSD symptoms and anger arousal. The direct relationships between PTSD symptoms and female-perpetrated physical and psychological dating violence were nonsignificant after controlling for the effect of anger arousal.     

Physical Health in Preschool Children Exposed to Intimate Partner Violence

Exposure to violence and traumatic events during childhood has long been associated with poor physical and psychological health during adulthood. Very few studies, however, have taken steps to understand the immediate relationship between exposure to intimate partner violence (IPV) and physical health problems in young children. In this study, we examined the mother-reported physical health problems of 102 preschool-age children who have been exposed to IPV. We found that children exhibiting more traumatic stress symptoms displayed fewer total health problems; however, gastrointestinal problems and asthma were related to poor psychological adjustment. We also found that preschool-age girls were more likely to display health problems than boys. Future studies of the physical health consequences of exposure to IPV in young children would benefit from examinations of specific changes in physiological processes to draw conclusions about the effects of violence on immune system functioning and physical health.     

The transfer of touch DNA from hands to glass, fabric and wood

The transfer of DNA from hands to objects by holding or touching has been examined in the past. The main purpose of this study was to examine the variation in the amount of DNA transferred from hands to glass, fabric and wood. The study involved 300 volunteers (100 for glass, 100 for fabric and 100 for wood) 50% of which were male and 50% female. The volunteers held the material for 60 s. The DNA was recovered from the objects using a minitape lift, quantified using the Quantifiler kit assay, extracted using a ‘Qiagen^® QIAamp DNA mini kit’ and amplified using the AmpFlSTR^® SGM Plus™ Amplification Kit at 28 cycles. The results show that using ANOVA there was a significant difference (F = 8.2, p < 0.05) between the three object types in the amount of DNA recovered. In terms of DNA transfer and recovery, wood gave the best yield, followed by fabric and then glass. The likelihood of success of obtaining a profile indicative of the holder was approximately 9% for glass samples, 23% for fabric and 36% for wood. There was no significant difference between the amount of DNA transferred by male or female volunteers. In this study good shedder status, as defined by obtaining useful profiles of 6 or more alleles, is estimated at approximately 22% of the population. The phenomenon of secondary transfer was observed when mixed DNA profiles were obtained but the incidence was low at approximately 10% of the total number of samples. DNA profiles corresponding to more than one person were found on objects which had been touched by only one volunteer. Although secondary transfer is possible the profiles obtained from touched objects are more likely to be as a result of primary transfer rather than a secondary source.     

“This case is about you and your future”: Towards Judgments for Children

A handful of ‘child-friendly’ judgments have emerged in the UK in recent years, attempting to adopt a child-centred approach to the decision-making stage of the legal process. Most notable is Sir Peter Jackson's judgment in Re A: Letter to a Young Person which, in taking the form of a letter to the child, has been applauded as a model of how to achieve ‘child friendly justice’. This article examines how and why the form and presentation of judicial decisions is an important aspect of children's access to justice, considering not just the potential but the duty of judges to enhance children's status and capacities as legal citizens through judgment writing. We identify four potential functions of judgments written for children (communicative, developmental, instructive and legally transformative), and call for a radical reappraisal of the way in which judgments are constructed and conveyed with a view to promoting children's access to justice.     

We are meeting on Microsoft Teams: Forensic analysis in Windows,Android, and iOS operating systems

Microsoft released a new communication platform, Microsoft Teams, in 2017. Due in part to COVID-19, the popularity of communication platforms, like Microsoft Teams, increased exponentially. Given its user base and increased popularity, it seems likely that digital forensic investigators will encounter cases where Microsoft Teams is a relevant component. However, because Microsoft Teams is a relatively new application, there is limited forensic research on the application particularly focusing on mobile operating systems. To address this gap, an analysis of data stored at rest by Microsoft Teams was conducted on the Windows 10 operating system as well as on Android and Apple iOS mobile operating systems. Basic functionalities, such as messaging, sharing files, participating in video conferences, and other functionalities that Teams provides, were performed in an isolated testing environment. Cellebrite UFED Physical Analyzer and Magnet AXIOM Examine tools were used to analyze the mobile devices and the Windows device, respectively. Manual or non-automated investigation recovered, at least partially, the majority of artifacts across all three operating systems. In this study, a total of 77.6% of the populated artifacts were partially or fully recovered in the manual investigation. On the other hand, forensic tools used did not automatically recover many of the artifacts found with the manual investigation. Only 13.8% of artifacts were partially or fully recovered by the forensic tools across all three devices. These discovered artifacts and the results of the investigations are presented in order to aid digital forensic investigations.
