Abstract: This study investigates the role of criminal dismemberment in sexual homicide crime-commission process. Specifically, this research aims to empirically determine whether criminal dismemberment is a rational behavior aimed at avoiding detection or an expression of sexual deviance. The sample used in this study comes from the Sexual Homicide International Database (SHIelD). Bivariate and multivariate analyses are performed to examine the differences between the crime commission process of sexual murderers who dismembered their victims (n = 77) and those who did not (n = 585). Findings indicate that criminal dismemberment occurred more often as part of a sexual deviance. Specifically, this behavior is strongly associated with the intention to kill the victim, necrophilia, mutilation of genitals, and commission of extreme acts committed on/with victims’ bodies. Moreover, findings showed that these offenders are more likely to follow an organized modus operandi. Theoretical and practical implications in terms of criminal investigations are discussed.
