The Police Role in Domestic Homicide Prevention: Lessons From a Domestic Violence Death Review Committee

This study examined the role of police in domestic homicide cases reviewed by a multidisciplinary death review committee in Ontario, Canada. Examining the 219 domestic homicide case summaries, this study explored the difference between homicides with, and without, prior police contact. Results indicated that police contacted cases had 63% more risk factors present compared with cases without prior police contact, with 80% of police-involved cases having 10 or more risk factors. Police cases had unique risk factors present including a failure to comply with authority, access to victims after risk assessments, prior threats to kill victims (including with a weapon), history of domestic violence (DV), extreme minimization of DV, addiction concerns, and an escalation of violence. Cases involving child homicide have unique child-specific risk factors such as custody disputes, threats to children, and abuse during pregnancy. Overall, there was a lack of formal risk assessments conducted. Implications are discussed in terms of police intervention being a critical opportunity for risk assessment, safety planning, and risk management. Although there is no certainty in predicting that lives would have been saved, the level of risk presented calls for enhanced efforts at assessment and intervention for adult victims and their children.
