Domestic homicide and other violent crimes: The same or different phenomena?

This study investigated correlates of domestic homicide (DH) and other violent crimes. Data were collected retrospectively from criminal justice files on 617 persons in Switzerland (DH = 47). Multinomial logistic regressions revealed that, overall, DH perpetrators were more likely to be older, female, married, to have a psychiatric hospitalization history, and to be under the influence of delusions when they committed the crime. In addition, they were less likely to have prior convictions. Furthermore, the characteristics associated to DH perpetrators were more similar to domestic violence perpetrators than those of persons who committed non-domestic offenses. Based on the current sample, data, and methods, DH appears to be better explained by specialist theories than generalist views of crime, suggesting that DH and the homicide of non-family members are different phenomena. Therefore, domestic offenders may require specific assessment and intervention methods. However, replications of this study are necessary to generalize the current findings.
