A Geospatial Analysis of the Crime Commission Process of Sexual Murderers

• In Event: Posters II

Abstract

While there are numerous empirical studies on sexual murderers (see James & Proulx, 2014), little attention has been given to the geospatial analysis of their sexual homicides. The aim of this study is to verify the hypothesis that geospatial sequence of serial sexual murderers' (SSMs) crimes differs from those of nonserial sexual murderers (NSMs) in terms of distances and multiplicity of locations (contact scene, attack scene, murder scene, body dump site). Informations of 110 sexual murderers (SSMs = 25, NSMs = 85) having committed a total of 174 homicides in France between 1960 and 2013 will be analyzed (Chi2, ANOVA). Geospatial (e.g., places of crime), situational (e.g., accomplice), and victimologic variables (e.g., gendre and age of the victim, level of risk, victim/offender relationship) will be analyzed in order to consider all the dimensions that can influence criminal mobility (Rossmo, Lu, & Fang, 2011). Results will help to improve investigation techniques in sexual homicide cases such as identify priority areas of inquiry, prioritize police interrogation of suspects, perform comparative analysis of sexual homicide unsolved cases in order to identify series.
