Abstract

As part of a wider research project into paraphilic disorders and homicide, a case is presented of a piquerist who achieved sexual satisfaction through the infliction of stabbing wounds. Against a background of sexual domination with willing and unwilling sexual partners, the offender stabbed four men to death. A study of the resulting autopsy reports, in association with the offender's testimony and crime scene documentation, was undertaken to discern a piquerist crime scene signature. An excessive number of stabbing wounds, the targeting of sexual areas, and a variation in wound size and depth were found to be evidence of piquerism. Although there was opportunity to commit a sexual assault upon victims, the preference was to penetrate them with a knife. It is contended that, even without any evidence of sexual assault at a crime scene, a knife wound analysis can reveal a sexual motivation in some cases of homicide.
