Which Agency Holds a Report from Dunellen
The report of an incident is released by the agency that took it; the court and the jail hold their own records of the same event, but not the report.
Inside Dunellen that is the agency that reports to the FBI for the city (filed by the FBI as Dunellen Police Department); outside it, the Middlesex County Sheriff's Office.
The FBI's list also places the Middlesex County State Police in Middlesex County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries Middlesex County College and Rutgers University at New Brunswick (campus police) and Prosecutor in Middlesex County (other agency), each with a records office of its own.
