Completed suicide and criminality: lack of a direct relationship

A comparison was made of the crime rate among 181 suicides and 181 controls, representing an unselected sample of the population matched with the suicides for sex, age, marital status, place of residence and occupational level. Sixteen per cent of the suicides and 11% of the controls had a criminal record, a statistically insignificant difference. In addition, no significant differences were found in the proportion of recidivists and of violent offenders, or in the number of their offences and convictions. A significant difference was found regarding the distribution of the offences by particular laws: more than a half of the offences committed by criminal suicides concerned violations of the road traffic laws, this being in agreement with the hypothesis that risky, accident-prone behaviour is a suicidal behaviour equivalent.
