Which Agency Holds a Report from Thomas 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 Thomas County that is the Thomas 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 Oakley Police Department is listed by the FBI across three counties including Thomas County, so its arrests are not broken out for Thomas County here.
