Which Agency Holds a Report from Rock Island 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 Rock Island County that is the Rock Island 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 carries Black Hawk College at Moline (campus police), with a records office of its own.
