The purpose of this paper is to examine the role of a variety of developmental factors on sexual homicide offenders (SHOs), while taking into account other components of sexual homicide theoretical models.,A series of logistic regression models are performed using a total of 616 incarcerated adult male sexual offenders from Canada to distinguish between three groups of sexual offenders, SHOs, violent non-homicidal sex offenders (NHSOs) and NHSOs.,Results indicate that contrary to theoretical models, experiences of victimization are not central to the development of SHOs. Instead, it is the adoption of various problematic behaviors in childhood that appear as most important in the etiology of this particular type of sexual crime. This suggests that the various existing theoretical models of sexual homicide need to be revised and/or tested with additional empirical data.,This is the first study to look at developmental factors using two control groups of NHSOs and violent NHSOs.

性谋杀的垫脚石：发展因素在性杀人案病因中的作用

本文旨在研究各种发展因素对性杀人罪犯（SHOs）的作用，同时考虑到性杀人罪理论模型的其他组成部分。使用总共616个逻辑回归模型进行了一系列将来自加拿大的成年男性性犯罪者监禁，以区分三类性犯罪者，即SHOS，暴力非杀人性犯罪者（NHSOs）和NHSO。结果表明，与理论模型相反，受害经历不是SHOS发展的关键。取而代之的是，在这种特殊类型的性犯罪的病因学中，童年时期采取的各种有问题的行为似乎最为重要。
