BACKGROUND The literature on recidivism by homicide offenders is scarce despite its importance for individuals and for society. AIMS To establish the rate of seriously violent re-offending among homicide offenders and identify risk factors for such recidivism. METHODS A 1970s incident cohort of all homicide offenders, sane and insane, from two regions(More)
BACKGROUND AND OBJECTIVES Previous research on the toxicology of homicide has shown that about half of offenders and victims have psychoactive substances in their blood. The purpose of this study was to examine this topic in a Swedish setting. METHODS Toxicological data were sought in a database for all victims (n=273) and perpetrators (n=257) of homicide(More)

This study examines the rate of child homicides during 21 years, with the hypothesis that a decline might be attributable to a decrease in the number of depressive filicide offenders (as defined by a proxy measure).

BACKGROUND Previous research suggests that female violent offenders at risk of a prison sentence are more likely than their male counterparts to be assessed as having mental health problems of a nature or degree that would lead to a court requirement for hospital treatment. AIMS/HYPOTHESES To test the hypothesis that there is bias towards hospital(More)
BACKGROUND In Sweden, the number of people serving life sentences has steadily increased. To date, few studies have examined the recidivism rate or the predictive validity of different risk assessment instruments in this group. AIMS Our aim was to test the predictive validity among inmates serving life sentences of two different instruments used for(More)
Although typically described as reliable and valid, the Psychopathy Checklist-Revised (PCL-R) has come under some criticism by researchers in the last half-decade due to evidence of poor interrater reliability and adversarial allegiance being reported in applied settings in North America. This study examines the field reliability of the PCL-R using a(More)
OBJECTIVE We aimed to assess the extent to which adherence to, and recreational use of, psychotropic medications influence the risk of homicide offending and victimization. METHODS We conducted a population-based case-control study by way of linking a nationwide registry of dispensed prescriptions with a forensic-toxicological database. Homicide victims(More)
