This study examined the interaction of some contextual and personality factors that influenced policemen and soldiers to commit murder-suicides. Authoritarian personality theory framed the study. Jamaican newspaper databases were searched for murder-suicides committed by the security forces. Content analysis of the 11 news stories found revealed contextual factors such as gender – all perpetrators were males and nearly all the primary targets females; age – the perpetrators were older than all the primary targets; occupational status and job rank – the perpetrators were in higher status occupations or in higher job ranks than most primary targets; domestic situations – the perpetrators and the majority of targets were domestic partners. These authoritarian men believed in conventionalism, authoritarian submission and authoritarian aggression. They experienced relationship problems and challenges from partners including some who terminated the relationship. These stressors triggered 11 incidents that killed 26 persons (17 targets and nine perpetrators) and injured two others over 18 years.
