Which Agency Holds a Report from Belvidere
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 Belvidere that is the agency that reports to the FBI for the city (filed by the FBI as Belvidere Police Department); outside it, the Boone County Sheriff's Office.
The Cherry Valley Police Department and the Loves Park Police Department are each listed by the FBI across several counties including Boone County, so their arrests are not broken out for Boone County here.
