It is well established that alcohol use is associated with homicide (e.g. Kuhns et al. 2014; Parker et al. 2011). However, much of our knowledge of alcohol-involved homicide is based on official data. Self-report data obtained directly from offenders about their consumption of alcohol immediately prior to committing homicide provide valuable information that complements data from official sources such as details emerging from police investigations and court proceedings. However, such data are rare. This study analyzes self-report data collected through face-to-face interviews with 205 men and women convicted of murder or manslaughter in Australia, of whom almost half (43.4%) reported use of alcohol prior to the homicide. The strongest predictor of alcohol-involved homicide was ongoing alcohol problems, speaking to the importance of prevention strategies targeting the entrenched nature of substance misuse. Furthermore, alcohol-involved homicides were nighttime events, committed in public places by older offenders using knives. Though such variables appear indicative of impulsiveness, a measure of self-control did not distinguish between alcohol-involved and not alcohol-involved homicide. Further investigations into the role of self-control on alcohol and violence are necessary.
