"Ex-Imprisoned Homicide Offenders: Once Bitten, Twice Shy?" The Effect of the Length of Imprisonment on Recidivism for Homicide Offenders

Summary: This study aims to examine recidivism patterns and the influence of imprisonment length for all homicide offenders who have been convicted in the Netherlands between 1996 and 2004. In addition, we tested whether imprisonment effects differed between homicide offenders with different characteristics. Analyses on 621 homicide offenders indicate that longer imprisonment systematically increases recidivism frequency, not recidivism speed. We find some indications that imprisonment length increases recidivism to a greater extent for offenders with an intimate partner, with a Western ethnic background and for offenders with a relatively shorter detention history prior to the homicide.
