The Detective Bureau provides comprehensive investigation services for the citizens of Warren Township. Detectives assigned to the Detective Bureau handle a variety of complex, in-depth investigations, including but not limited to suspicious deaths, missing persons, sexual assaults, burglaries, financial crimes, computer crimes, fraud, robberies and narcotic related offenses. Detectives are also responsible for pre-employment background investigations as well as background investigations for various permits such as firearms, soliciting and liquor licensing.

 

Within the Detective Bureau, there are two subcomponents, Criminal Investigations and Juvenile Investigations. These units are supervised by a Detective Sergeant.

 

The Criminal Investigations section is primarily responsible for locating and interviewing victims and witnesses; locating, identifying and preserving physical evidence; recovering stolen property; identifying, locating, interviewing and arresting criminal suspects; and presenting cases to the Somerset County Prosecutor's Office for criminal prosecution.

 

The Juvenile Investigations section is responsible for the prevention and control of juvenile delinquency problems as well as the investigation of juvenile related cases. The Juvenile Investigations section along with the School Resource Officers (SRO) are required to maintain a close liaison with the our six schools administrations, and staff, who provide important feedback as to the concerns of the students and parents.

 

The Detective Bureau investigates an average of 200 cases per year and the two Detectives and Detective Sergeant are on call 24 hours a day to assist the Patrol Division when called upon.
