Perpetrator related analysis of intentional homicides in the Genf canton (1971-1990)

A retrospective offender-related analysis was conducted on all deliberate homicides committed in the canton of Geneva between 1971 and 1990. The cases analyzed included 97 convicted single perpetrators or accomplices and 93 victims. 21 further homicides remained unsolved. 86.6% of the offenders were male; foreigners were over-represented in comparison with Swiss citizens. The average age was 35 years. In a majority of the cases the offender and the victim were partners, came from the same family or were acquainted with each other. Guns or knives were the most frequently used weapons. The criminal offences tried in Geneva were evaluated also with regard to their legal qualification.
