Strengthening Canadian Law Enforcement and Academic Partnerships in the Area of Online Child Sexual Exploitation: The Identification of Shared Research Directions

This article outlines the law enforcement response to online child sexual exploitation and identifies two key areas of research that would benefit from an academic focus—the link between online and offline child sexual exploitation offending, and the psychological health and wellness of online child sexual exploitation investigation employees. While there are several areas in need of research, these two areas demonstrate a unique opportunity for collaborative work. Also highlighted is a joint international research partnership among law enforcement, practitioners and academia that demonstrates the benefits of linking academic research interests with the practical needs of law enforcement. Last, are several suggestions for operationally relevant collaborative research in this area. Such opportunities bring together various areas of expertise, which will advance our understanding of the needs of victims, and improve victim support services.     

暴力危及飞行安全罪

暴力危及飞行安全罪的直接结果是被施暴者人身伤亡,构成要件结果是危及飞行安全,侵犯客体是飞行安全,主观方面包括故意和过失。暴力包括一切足以危及飞行安全的暴力;在飞行中是指在空中飞行中,不包括在跑道上滑行或停止状态;严重后果是指危及飞行安全的严重后果,不包括直接结果。     

女性暴力犯罪研究

随着社会的发展和文明的进步,女性在社会和家庭中地位不断提高,并发挥着越来越重要的作用。但女性暴力犯罪也日益突出并受到社会各界的关注。因此,研究女性暴力犯罪问题迫在眉睫。     

A Study of the Background Levels of Male DNA on Underpants Worn by Females

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault.     

Postmortem Changes of Female External Genitalia and Their Importance in Suspected Sexual Abuse

Examination of the female external genitalia to assess for sexual abuse is performed in living individuals, and the interpretation of the findings is based on evidence-based studies. However, in the deceased, no such studies are available, and postmortem changes could present as suspicious findings that can be mistaken for trauma. Patches of discoloration in the hymen were reported previously in one case as hypostasis (i.e., livor and lividity), and based on this finding, it was listed as a finding that is not associated with trauma. This was a retrospective study that was conducted in the Center of Forensic and Legal Medicine in Dammam, Saudi Arabia over a 4-year period. The study included 30 deceased women in whom photographic documentation of their external genitalia was assessed for postmortem changes. The postmortem interval ranged from less than 24 h to more than 100 days, and the ages of these deceased women were in the 20–40 year-old age group. In cases where the hymen, vagina, and/or fossa navicularis were clearly visible, none of these areas showed any hypostatic discoloration. A comparison between antemortem and postmortem appearance of the hymen in one case clearly showed the absence of hypostatic changes in the hymen. In conclusion, any discoloration of the external genitalia that is detected in a female decedent requires serious consideration.     

Sharp Force Homicide in Denmark 1992–2016

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992–2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.
