Studies investigating the link between major mental disorders and homicide have shown that schizophrenia was associated with the highest rate of homicide. In contrast, mood and anxiety disorders were associated with the lowest rate. Although the number of homicide offenders with mental disorders cannot be neglected, multiple confounders affect the relationship between homicide rates and mental illness, such as a history of an abusive childhood, previous violent acts, substance abuse, homelessness, unemployment, and divorce. Additionally, the stigma of mental illness seems to be the root of most, if not all, of these factors. Finally, studies on victim characteristics have shown that mentally ill offenders’ victims were individuals in close relationships with them, such as family members or friends, rather than strangers.
