Homicide in the Canadian Prairies: elderly and nonelderly killings.
OBJECTIVE
To examine the psychosocial and clinical characteristics of male perpetrators of elderly and nonelderly homicides in the Canadian Prairies.


METHODS
We examined data drawn from a study of 901 adult homicide offenders who were incarcerated or on parole between 1988 and 1992 in Alberta, Saskatchewan, and Manitoba.


RESULTS
Of those studied, 67 men were convicted of homicide involving 79 elderly victims, and 671 were convicted of homicide involving 675 nonelderly victims. Most perpetrators were single and engaged in irregular patterns of employment at the time of their index offence. Fourteen (20.8%) offenders with elderly victims had a history of psychiatric treatment, compared with 98 (14.6%) offenders with nonelderly victims; however, this difference was not statistically significant. Approximately 30% of both groups were diagnosed with personality disorders. A comparison of the index- offence characteristics showed no significant differences between the 2 groups.


CONCLUSIONS
Our findings suggest that elderly individuals are more likely to be killed in their own homes by strangers. Social isolation appears to be a significant risk factor in cases of elderly homicide.
