Criminal Cases in the Circuit Court of Whiteside County

For Whiteside County, SearchSystems opened and checked the court records page for the county at whitesidecountyil.gov/216/Circuit-Clerk (page title: Circuit Clerk | Whiteside County, IL), phone 815-772-5188, 200 East Knox Street Morrison, IL 61270, which answered when SearchSystems opened it on October 11, 2026.
Illinois has no single public index of every trial court case; each court's records are looked up through that court.
The Illinois Criminal History and Your Own Copy
Illinois is one of the states that lets anyone look up another person's statewide criminal history: conviction information is public under the Uniform Conviction Information Act, through the Illinois State Police. The result is the repository record, what agencies reported to the state, which is wider than one county's court index but can lag it.
To see your own record, the route is a name-based or fingerprint-based request to the Illinois State Police. The state page SearchSystems verified for it is at isp.illinois.gov/BureauOfIdentification/MyRecord.
