ABSTRACT Few existing studies have explored the relationship between facet-levels of psychopathy and different types of homicide. This study analyzed Korean homicide offenders’ psychopathic traits that were assessed by the Psychopathy Checklist-Revised (PCL-R) and compared family homicide offenders to those who killed complete strangers, and to those who killed nonfamily acquaintance victims. The study used the four psychopathy facet scores, age, education, and gender as predictors to postdict the three types of homicide. Multinomial logistic regression as well as Somer’s d tests revealed that psychopathic traits differentially contributed to the different forms of deadly violence. Compared to family homicide, stranger homicide scored higher on facet 2 (affective), facet 3 (lifestyle), and facet 4 (antisocial), but lower on facet 1 (interpersonal). In the similar sense, nonfamily homicide scored higher on facets 3 and 4, but lower on facet 1, when compared to family homicide. Family homicide offenders’ higher deficit in interpersonal traits (higher scores on facet 1) has been discussed, but merits further analysis. In addition, homicides by men tended to be extrafamilial, whereas killings by women were more likely to be intrafamilial. The study suggests interesting insights on differences in psychopathy and gender in the typology of homicide.
