Studies on female sex offending have been limited for a number of reasons, such as societal perceptions that females are incapable of engaging in such behaviors because of their role as caretakers and nurturers in society. However, over the past few decades, studies examining female sex offenders have increased, revealing that females do commit sexual offenses and differ from their male counterparts. We examined offender, victim, and offense characteristics of female sex offenders who were convicted from 1995 to 2013 (N = 223) in Arkansas and were sentenced to serve time in prison or placed on probation. We focused on the similarities and differences of solo and co-female sex offenders because we know from previous studies that the pathway of offending can differ between solo and co-female offenders, yet few studies have exclusively compared the similarities and differences among female sex offenders. Our data were collected from offender files that included basic personal offender information, offender survey and social history, criminal history, incident reports while incarcerated, court records, police investigation reports, initial offender and victim statements (prior to offender incarceration), and probation/parole reports. We believe the results of this study will provide further insight into the types of female sex offenders as well as the possible differences between co- and solo-offenders in relation to their victim preferences, risk levels, rehabilitation amenability, and recidivism propensities.
