Intimate partner homicide, immigration and citizenship: evidence from Norway 1990–2012

Abstract Intimate partner homicides (IPH) are fatal violent attacks perpetrated by intimate partners. Immigrants are overrepresented in the IPH statistics as both perpetrators and victims. If explanatory factors for this are not studied, immigrants may be stigmatized. The present study investigates whether IPHs committed by immigrant perpetrators have characteristics that differentiate them from IPHs committed by the native majority of IPH perpetrators. All IPHs in Norway from 1990 to 2012 (N = 177) were included. Quantitative data were extracted through structured investigation of court documents. Information concerning risk factors (previous intimate partner violence and sociodemographic, contextual and clinical factors) was drawn from three validated risk assessment instruments. Univariate analysis and multivariate logistic regression analyses were conducted. When adjusted for other group differences, very few differences remained in the multivariate models. IPHs perpetrated by immigrants differed from cases with native perpetrators on modus operandi and ascribed motives and resulted in longer sentences than IPHs with native perpetrators. This study indicates considerable similarities in IPHs perpetrated by immigrants and natives. Findings indicating that IPHs by immigrants were perceived differently in the justice system need further investigation.
