Which Agency Holds a Report from Trenton
A crime, incident or collision report belongs to the agency whose officer wrote it, and that agency releases it, not the court, the jail or the prosecutor.
Inside Trenton that is the agency that reports to the FBI for the city (filed by the FBI as Trenton Police Department); outside it, the Mercer County Sheriff's Office.
The FBI's list also places the Mercer County State Police in Mercer County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's agency list also places two campus police departments, one state agency and one other agency in Mercer County, each with a records office of its own.
