Abstract

<p>This study examined the transitions among sexual crimes in 519 sexual offenders, as well as the relationships between sexual and theft crimes. The author analyzed a dataset of 519 sexual offenders who had together committed a total of 15 crimes. The results of a correspondence analysis and hierarchical cluster analysis revealed that the 7 sexual crimes could be categorized into three types along two dimensions (where the crime took place and whether physical contact was involved): (1) contact type (e.g., indoor and outdoor rape, indecent assault including against youth), (2) non-contact type (e.g., exhibitionism and voyeurism), and (3) theft type (e.g., undergarment theft). The eight theft crimes were also classified into three types: (1) theft through breaking and entering (e.g., residential or commercial burglary), (2) vehicle theft (e.g., motor, motorcycle, and bicycle), and (3) non-breaking-and-entering theft (e.g., theft from a vehicle or shoplifting). The results suggested that (1) indecent assault offenders tend to transition to indoor rapes and (2) exhibitionists tend to transition to indecent assaults against youth. Furthermore, the contact type was moderately associated with vehicle theft, while indoor rapes specifically were related to theft through breaking and entering. The non-contact type was weakly connected to theft crimes.</p>
