Previous studies on multiple perpetrator rapes have shown that male sexual offenders who commit their offense alone differ on offender, offense, and victim characteristics from those who commit their offense in duos and 3+ groups. For the current study, 246 female sexual offenders have been studied regarding their co-offending pattern and the differences in offender, offense, and victim characteristics. Significant differences between solo (n = 73), duos (n = 146), and 3+ group offenders (n = 27) were found for the age at the first conviction, age at the time of the index offense, performed sexual acts, physical and verbal violence, victim gender, victim relationship, victim age, and location where the abuse took place. There were four indicators that could predict the assault type. Co-offenders were more likely than solo offenders to perform penetration on a female, intrafamilial victim who they assaulted indoors. These results have implications for interventions with offenders and criminal justice authorities.
