This book first provides an overview of murder-suicide in educational settings, with an emphasis on K-12 schools, and recommendations for the prevention of murder-suicide in educational settings are provided. This compilation also assesses the potential impact of increasing incarceration rates on homicide rates within 27 OECD nations from 1993 to 2005, suggesting areas for future research, including specification of the incarceration/homicide association in cross-national samples. The authors close by providing base-line frequencies for what offenders do after killing of a stranger. Further, they seek to identify whether associations can be made between post-offence behaviours and offender, victim, and offences characteristics.
