A B S T R A C TThe most alarming type of intimate partner violence is homicide. Violence risk assessment of intimate partner violent offenders is a common topic in police and prison contexts with the aim of preventing recidivism and fatal results. The purpose of this study was to analyze whether men who kill their intimate partner (intimate partner homicide -IPH) present different risk factors from those who kill women outside of a relationship (non-intimate partner homicide -non-IPH). The crime characteristics of 30 attempted or completed IPHs that were sentenced in Catalonia (Spain) between 2004 and 2009 are described. Moreover, the risk factors of 21 completed IPHs and 20 non-IPHs were compared using the RisCanvi, an actuarial risk assessment tool used in the Catalan prison context to manage inmates. Results show differences between the two types of offenders in the criminal role and recklessness, more prevalent among non-IPHs, which is consistent with research indicating that IPH offenders are similar to other homicide offenders. The difficulties faced seeking to assess and manage the risk of IPH are discussed.
