Abstract:
Serious injuries and deaths of three samples of boys were examined in an inner-city, longitudinal study. By age 19, almost 1 in 10 of the 506 participants in the oldest sample had been seriously wounded or killed. Two thirds of this group had been either wounded or killed by guns. Victims, compared to controls, tended to have a history of engaging in serious delinquency, gang fights, and selling drugs. They also tended to carry guns. The delinquent lifestyle of the victims was also evident from their court records. Victims tended to do poorly academically in school, received poorer parental supervision, had poorer communication with their parents, and had a long history of behavior problems.
