Abstract

This narrative review examines different aspects of homicide among mentally ill individuals to compare the rates of homicide by offenders with and without mental illness and investigate the stigma of mental illness and its consequences. It also evaluates the motives of mentally ill perpetrators and their characteristics and explores weapons of choice in homicides related to different mental disorders. Studies confirmed higher homicide rates among specific categories of mentally ill individuals who experienced maltreatment, unemployment, abuse in childhood, and substance abuse resulting from stigma and discrimination. The motives were mainly revenge, argument, financial gain, sexuality, sadism, and filicide, with revenge being the top motive. Offenders were found to have close relationships with their victims in most cases. Sharp instruments were the most commonly used weapons. Our review confirms the lack of evidence linking mental illness independently with homicide, both globally and in Arab countries, and highlights the impact of discrimination toward mentally ill individuals. This discrimination and stigma lead to delayed care-seeking and self-destructive behavior, which is linked to higher homicide rates among persons with and without mental illness.
