Forensic aspects of 40 accidental autoerotic deaths in Northern Germany

Between 1983 and 2003, 40 accidental autoerotic fatalities have been investigated. in the Institute of Legal Medicine in Hamburg. Only 50% (n = 20) were autopsied (13 legal autopsies, 6 for scientific purposes and 1 for an insurance company). All the victims were males, aged between 13 and 79 years (among them five children and adolescents, the deceased mainly between 20 and 40 years). The paraphiliacs utilized a great range of devices and props as fetishism, sexual aids or pain-stimulating agents, like intimate feminine garments, ropes, chains, bondages, locks, pornographic magazines, condoms, rubber items, and chemical anaesthetics. The cause of death was strangulation in 20 cases (17× hanging, 3× ligature strangulation), 11× suffocation (8× under plastic bags, 3× with face-masks, 2× thoracic compression, 1× positional asphyxia, and 1× cocaine intoxication). Five cases without autopsy remained unclear because of missing morphological and toxicological findings; it could not be differentiated between asphyxiation/intoxication/natural disease, although the scene characteristics seemed to be typical for autoerotic deaths. It is emphasized that the findings at the scene, the morphological and toxicological examination of the dead body (full autopsy as prerequisite) by experienced investigators and the personal history of the deceased have to be evaluated very carefully and intensely to reconstruct the accidental fatal autoerotic course accurately and undoubtedly (to exclude the possibility of sexual homicide, neglected killing, or suicide).
