Sexual homicides involving elderly victims are rare and unusual crimes, and research specifically focusing on these homicides is almost inexistent. The current study investigates the crime commission process as well as the motivations underlying elderly sexual homicides. The sample comes from the Sexual Homicide International Database (SHIelD) including sexual homicide cases from Canada and France. A total of 56 cases involving victims aged 65 years or more were compared with 513 cases involving victims aged between 16 and 45 years old. Bivariate analyses and two-step cluster analysis are performed. Findings show major differences in the crime commission process of the two groups of offenders. We also identified a four-cluster typology of elderly sexual homicide offenders based on their motivations (sexual, robber, sadistic, experimental). Although sexual homicides involving elderly victims are rare, these crimes are different, presenting specificities and should be studied as a group on its own.
涉及老年受害者的性杀人案件是罕见且特殊的犯罪，专门针对这些杀人案件的研究几乎不存在。当前的研究调查了犯罪实施过程以及老年性杀人案件背后的动机。样本来自性杀人国际数据库（SHIelD），包括来自加拿大和法国的性杀人案件。总共56起涉及65岁及以上受害者的案件与513起涉及16至45岁受害者的案件进行了比较。进行了双变量分析和两步聚类分析。研究结果显示两组犯罪者在犯罪实施过程中存在重大差异。我们还根据动机（性、抢劫、虐待狂、实验性）确定了老年性杀人犯罪者的四类类型。尽管涉及老年受害者的性杀人案件很少见，但这些犯罪是不同的，具有特殊性，应该作为一个单独的群体进行研究。
