Female homicide has been associated with several psychiatric disorders. Thi
s distinct field seems to be in need of more research, and therefore we wan
ted to explore the homicidal women of Finland. We studied written reports o
f forensic psychiatric evaluations of female offenders committing homicide
or attempted homicide during the years 1982-92. Of the investigated women,
28.0% were diagnosed with a psychotic illness, 43.9% with alcoholism and 72
.0% with a personality disorder. Comorbidity was common. Only 38.6% of the
studied women had a single diagnosis. Those diagnosed as psychotic were not
considered legally responsible for their acts. Most offenders had had prev
ious psychiatric care. All the women committing neonaticide were diagnosed
with a personality disorder and none was deemed fully responsible for her a
ct. Further analyses with a new study design might elucidate the characteri
stic homicidal woman.
