xisting studies point to relationships between child abuse and crime perpetration in adulthood. We also know that child abuse and trauma are strongly connected to mental health. In this study, the relationship between child abuse and neglect, OP, lead poisoning, and involvement in serious offenses including murder and homicide, prior to adulthood was completed. This study explored the links between prevalence of child abuse and neglect, out of home placement, and child lead poisoning and arrest for serious offenses before adulthood. Findings showed that prevalence of abuse and neglect significantly predicted prevalence of arrest for violent and serious crimes. OP did not have a significant relationship with arrest for serious and violent crimes. Prevalence of lead poisoning exposure was not significantly associated with prevalence of arrested for serious crime. Implications on child protection, mental health, and social work education are discussed.
