Which Agency Holds a Report from Mariposa County
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.
In Mariposa County that is the Mariposa County Sheriff's Office for the unincorporated county and for any city that contracts with it for police service, and the agency that reports for a city where the city has one of its own.
The FBI's list also places the Highway Patrol's Mariposa Area Office in Mariposa County; a report taken on a state highway by it comes from that agency's own records office.
The FBI's list also carries California Department of Forestry and Fire Protection at Madera-Mariposa-Merced (state agency), with a records office of its own.
