Criminal Expertise and Sexual Violence: Comparing the Crime-Commission Process Involved in Sexual Burglary and Sexual...

Criminal expertise relates to the notion that some individuals may develop domain-specific offending skills that differentiate them from those with less skills or experience (i.e., novices). In the expertise literature, burglary has emerged as a distinct type of "expert" offense, therefore the current study sought to determine whether criminal expertise is more evident in the crime-commission process of sexual burglary compared to sexual robbery. We used binary logistic regression to compare the pre-crime, crime, and post-crime behaviors of 870 cases of hybrid sexual assault that occurred during the commission of either a burglary (N = 319) (or) robbery (N = 479), both of which involved personal theft from a stranger victim. Findings suggest that the crime commission process of sexual burglary involves a more sophisticated modus operandi and greater expertise in detection avoidance (e.g., strategies to protect their identity and destroying and removing evidence) compared to sexual robbery.
