Journey "During" Crime: Predicting Criminal Mobility Patterns in Sexual Assaults.
ABSTRACT The aim of this study was to test whether there is a relationship between situational and modus operandi characteristics and criminal mobility during the sexual assault event. Data collected from both police files and semistructured interviews with 72 serial sex offenders who have committed 361 sexual assaults have been used. Negative binomial regression was used to identify the relationships between the situational and modus operandi characteristics and the criminal mobility exhibited during the sexual assault. Events that involved child or adolescent victims, those where the offender did not use pornography prior to crime, and those where victim resistance was observed exhibited more criminal mobility. Moreover, crimes in which the victim was selected, the victim was alone when approached by the offender, and the assault was characterized by sexual penetration and a lack of premeditation exhibited more criminal mobility. Results seem to suggest that criminal mobility is a goal-oriented action taken by serial sex offenders to successfully complete their crime and to avoid detection and apprehension.
