Juvenile Detective

The juvenile detective investigates and processes all juvenile matters handled by the police department. Typically, these cases initially begin with uniform officers from the patrol division; they are turned over to the juvenile detective for follow-up. The juvenile detective works closely with the NJ Department of Children and Families as well as the Mercer County Prosecutor's Office on investigations involving mistreatment and neglect of children. The juvenile detective also serves as the liaison officer in the Timberlane Middle School and the Hopewell Valley Central High School.
