These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. Serial sexual assault is a pervasive problem: court record recidivism rates show that 10-15% of convicted sex offenders re-assault within five years and self-report studies suggest that 63-78% of males who have committed sexual assaults have raped more than one individual. The current study documents the scope of repeat sexual offending through a previously-unexplored method of documenting serial perpetration: DNA evidence in sexual assault kits (SAKs). Ultimately, the testing of N = 7,287 previously untested SAKs revealed n = 1,270 unique and identifiable perpetrators. When combined with information from lifetime criminal history records, 39.7% (n = 504) of this subsample of unique and identifiable perpetrators were found to be serial sexual offenders who committed, on average, 3.27 sexual assaults.
