ABSTRACT

Although similar subtypes of sexual homicide have been described cross-nationally, no study has directly examined whether two samples from different jurisdictions are comparable. This study therefore aimed to examine whether any substantively meaningful subtypes of sexual homicide cases could be identified in each sample, and if so, whether these subtypes were similar across jurisdictions. Two samples of male sexual homicide offenders were compared: a Scottish sample (n = 89) and a Canadian sample (n = 150). Subtypes were identified in each sample using LCA, identifying a 3-class solution in each sample. Despite differences between samples on the bivariate level, two very similar subtypes (Controlled-Organized and Diverse) emerged in both samples. Despite differences at the bivariate level, the similarities at the multivariate level indicate similarities in underlying offence pathways which underpin heterogeneity in sexual homicide offenders. The similarities between the subtypes identified suggests potential universality of types of sexual homicides cross-nationally.

抽象的

尽管跨国性描述了类似的性杀人亚型，但尚无研究直接检查来自不同司法管辖区的两个样本是否具有可比性。因此，本研究旨在检验在每个样本中是否可以识别出任何实质意义上的性杀人案件亚型，如果可以，在不同的司法管辖区中这些亚型是否相似。比较了男性杀人罪的两个样本：苏格兰样本（n  = 89）和加拿大样本（n  = 150）。使用LCA在每个样品中鉴定了亚型，从而在每个样品中鉴定了3类溶液。尽管在双变量水平上样本之间存在差异，但两个非常相似的亚型（受控组织和多元）出现在两个样本中。尽管在双变量水平上存在差异，但在多变量水平上的相似之处表明，潜在的犯罪途径之间的相似之处是性杀人罪犯异质性的基础。所确定的亚型之间的相似性表明，跨国性性杀人罪类型具有潜在的普遍性。
