Abstract
Research on young persons who commit homicide has largely focused on associative factors rather than event characteristics. This paper uses 25 years of data from the National Homicide Monitoring Program to describe the characteristics of homicide incidents perpetrated by offenders aged 10–17 years. In particular it examines if young homicide offenders are more likely to co-offend and if incident, victim and offender characteristics vary depending on whether the young person killed on their own or with others.
