Results from three separate analyses suggest that all three groups of subjects have a similar exposure to risk conditions, but also that there are important differences in the predictors for the three groups when the risk factors are analyzed one by one. Such as, the experience of domestic violence during adolescence is a strong predictor of males’ later violent behavior but a less strong predictor of suicidal behavior. In contrast, being battered and being neglected during childhood more strongly predicts later suicidal behavior than violent behavior. These results are from a systematic study of the social background of Danish males convicted for the first time of lethal violence. It examines whether young men, convicted of a lethal violent crime, have the same kind of risk factors related to social disadvantage as other first-time convicted violent offenders and first-time attempted suicides or completed suicides. The study describes 3 separate analyses of the total 1,966 birth cohort followed through a 13-year period from age 15 to 27 (n = 43,403). Tables, references and appendix
