Which Agency Holds a Report from Oakley
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 Oakley that is the agency that reports to the FBI for the city (filed by the FBI as Oakley Police Department); outside it, the Contra Costa County Sheriff's Office.
The FBI's list also places the Highway Patrol's Contra Costa Area Office in Contra Costa County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries San Francisco Bay Area Rapid Transit in Contra Costa County and Union Pacific Railroad in Contra Costa County (other agency) and Contra Costa Community College (campus police), each with a records office of its own.
