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.

犯罪专业知识涉及这样一种观念，即某些个人可能会发展特定领域的犯罪技能，从而将他们与那些技能或经验较少的人（即新手）区分开来。在专业知识文献中，入室盗窃已成为一种独特的“专家”犯罪类型，因此当前的研究试图确定与性抢劫相比，犯罪专业知识在性入室盗窃的犯罪过程中是否更明显。我们使用二元逻辑回归来比较 870 起混合性侵犯案件的犯罪前、犯罪和犯罪后行为，这些案件发生在盗窃 ( N = 319) (或) 抢劫 ( N= 479），两者都涉及陌生人受害者的个人盗窃。调查结果表明，与性抢劫相比，性盗窃的犯罪实施过程涉及更复杂的作案手法和在避免被发现方面的更多专业知识（例如，保护其身份以及销毁和移除证据的策略）。
