Multiple einzeitige tötungsdelikte - Forensische und kriminologische aspekte

The interpretation of medicolegal findings in homicide is an important tool of case profiling (so-called "operative case analysis"). In 17 cases of "multiple homicides" involving 22 offenders (21 males, 1 female; mean age 33 years) and 45 victims (21 males, 24 females; mean age 35 years; 41 fatalities, 4 survivors), the autopsy reports and the prosecution authorities' files were retrospectively analysed with regard to individual characteristics of perpetrators and victims, circumstances, and mode of commitment in order to comprehensively characterise relevant forensic and criminologic aspects. 31 victims were found to belong to the close social environment of the perpetrator, and 32 killings were committed in the victim's, perpetrator's or the joint flat. The main motives included greed (n = 7), personal conflicts (n = 5) and concealing of a crime (n = 9). The relevant injuries were attributable to gunshot wounds (n = 13), sharp force (n = 11), blunt force (n = 3), ligature strangulation (n = 3), smothering (n = 6), fire/carbon monoxide (n = 2) and combined impacts (n = 7). In 12 victims, defense injuries were found. The blood alcohol concentration exceeded 1.5 g/l in 5 victims. In 5 offenders, a psychiatric impairment of juridical responsibility was assessed § 20 German criminal code, n = 1, psychosis; § 21 German criminal code, n = 4; acute alcohol intoxication). As far as data were available, 16 crimes were judged as murder, 12 as manslaughter and one as physical injury with fatal outcome.
