Abstract

Information on sexual homicide offenders is limited. The current study estimates the rate of sexual homicides in Finland and analyses sociodemographic characteristics, crime history, life course development, psychopathy, and psychopathology in sexual homicide and nonsexual homicide offenders. Crime reports and forensic examination reports of all offenders subjected to forensic examination and convicted for homicide in 1995-2004 (n=676) were retrospectively analyzed for offence and offender variables and scored with the Psychopathy Checklist-Revised. Eighteen sexual homicides (2.8%) were identified. Co-offending, strangulation and disposal of the body were more frequent crime scene variables in sexual than nonsexual homicides. Mental health problems and sexual abuse in childhood and sexual crime history were significantly more frequent in sexual than nonsexual homicide offenders. Over half of the sexual homicide offenders were psychopathic: compared to nonsexual homicide offenders they scored significantly higher on interpersonal and affective features of psychopathy.
