This study aims to empirically explore the crime-commission process of juvenile sexual homicide offenders (SHOs). First, a comparison between the crime-commission process of juvenile and adult SHOs is undertaken, while as a second step, this study also provides an empirical classification specific to juvenile SHOs. The sample used in this study consists of 55 juvenile SHOs and 281 adult SHOs. A sequential binomial regression was used to compare at the multivariate level the two groups of offenders, while a latent class analysis was used to examine the relationships between each step of the crime-commission process of juvenile SHOs. Our findings suggest that the crime-commission process of juvenile SHOs present differences when compared with adult SHOs. Moreover, we identified four different patterns in juvenile sexual homicide: explosive opportunistic, sadistic, overcontrolled anger, and predator. Theoretical and practical implications in terms of criminal investigations as well as offenders' management and treatment are discussed.
本研究旨在对青少年性杀人罪犯（SHO）的犯罪过程进行实证研究。首先，对青少年 SHO 和成年 SHO 的犯罪过程进行比较，其次，本研究还提供了针对青少年 SHO 的具体实证分类。本研究使用的样本包括 55 名青少年 SHO 和 281 名成年 SHO。使用顺序二项式回归在多变量水平上比较两组罪犯，同时使用潜在类别分析来检验青少年 SHO 犯罪过程中每个步骤之间的关系。我们的研究结果表明，青少年 SHO 的犯罪过程与成年 SHO 存在差异。此外，我们在青少年性杀人案件中确定了四种不同的模式：爆发性机会主义、施虐狂、过度控制的愤怒和捕食者。讨论了在犯罪调查以及罪犯管理和治疗方面的理论和实践意义。
