Stepping stones to sexual murder: the role of developmental factors in the etiology of sexual homicide. Eric Beauregard et al. Journal of Criminal Psychology, http://dx.doi.org/10.1108/JCP-02-2018-0010

Abstract:

Purpose: 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.

Design/methodology/approach: 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.

Findings: 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.

Originality/value: This is the first study to look at developmental factors using two control groups of NHSOs and violent NHSOs.
