Autoerotic nonlethal filmed hangings: a case series and comments on the estimation of the time to irreversibility in hanging

Asphyxia homicides in Denmark 1992-2016

In this retrospective study , we present the findings in 250 homicides by asphyxia in Denmark in a 25-year period, with a particular focus on the autopsy findings in strangulation. Our intention is for the results to be used in future death investigations, where difficulties in interpretation of findings in potential asphyxial deaths arise. Asphyxia homicides showed a strong bias with respect to sex, age, and homicide type. The frequent female victim was typically an adult, whereas the rarer male victim was most often a child. Female offenders most often killed their children, and male offenders most often killed their female partner. Generally, most asphyxia homicides took place in a domestic setting. Manual strangulation and ligature strangulation were the most common mechanisms of asphyxia homicides (81.6%). A lack of petechial hemorrhages, especially in the conjunctiva, was rare in homicidal strangulation, but there were exceptions, especially when there was postmortem decomposition, making it impossible to verify them. Most victims of strangulation had skin lesions in the face (including the jawline) or on the neck, with accompanying hemorrhages in muscle and connective tissue, but the findings could be subtle or compounded by decomposition. Fractures of the laryngo-hyoid complex were common in strangulation, particularly in manual strangulation (chi-sq = 4.0993, df = 1, P < 0.05) and were clearly related to the age of the victim (chi-sq = 82.193, df = 4, P < 0.001). In children and young adults dying from homicidal strangulation, a lack of fractures is to be expected, while a lack of fractures is unusual, but not entirely unexpected, for adults and aged people.

Fatal strangulation during consensual BDSM activity: three case reports

Autoerotic accidents are well-known occurrences in forensic casework. Reports about unintentional deaths in a sexual context involving other persons are much rarer. Three cases of fatal incidents related to asphyxiophilia during consensual BDSM activity are reported. Two men died while visiting a dominatrix, the third one in the presence of a male casual sexual partner. Paraphernalia associated with BDSM/fetishism were found at the scene in all cases. Autopsy findings were compatible with death by strangulation. The cases are compared with published autoerotic accidents and similar unintentional deaths involving other individuals. The difficulties concerning the forensic assessment and reconstruction of the cases are discussed.

Current reports on autoerotic deaths--five persistent myths

Autoerotic deaths are defined as accidental deaths that occur during individual, solitary sexual activity in which some type of apparatus that was used to enhance the sexual stimulation of the deceased caused unintentional death. In the Western countries, the incidence of these deaths is of approximately 0.5 deaths per million inhabitants per year. In this paper, five myths about autoerotic death are explored. Myth #1: the manner of death in autoerotic death is usually accidental but could also be suicidal or natural (reality: by definition, all autoerotic deaths are accidental). Myth #2: autoerotic death can happen with a sexual partner (reality: by definition, autoerotic deaths are solitary activities). Myth #3: an escape mechanism must be found at the scene (reality: there is no escape mechanism to be observed at the scene in the majority of autoerotic deaths). Myth #4: all autoerotic deaths are related to asphyxia (reality: not all autoerotic deaths are related to asphyxia). Myth #5: masturbation is an important component of all autoerotic activities and therefore all autoerotic deaths (reality: evidence of masturbation at the scene is a rare finding).
