Macon County, Illinois, has about 101,000 residents (2024 Census Bureau estimate).

Criminal Cases in the Circuit Court of Macon County
A criminal case from Macon County is filed in the Circuit Court of Macon County, and the court file, kept by the Circuit Clerk, is the record of it that the public may see.
For Macon County, SearchSystems opened and checked the court records page for the county at apps.ilsos.gov/isairad/maconsrch.jsp (page title: Macon County Circuit Court Case Files Index, 1829-1861), which answered when SearchSystems opened it on September 23, 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.
Arrest Records Kept Locally in Macon County
The Macon County Sheriff's Office and the agencies that report for Decatur, Mount Zion, Maroa, Blue Mound and Warrensburg keep the arrest records in Macon County: the report and the booking record of each arrest stay with the agency that made it, separate from the court file and from the state repository.
The FBI's agency list also places two other agencies and two campus police departments in Macon County (the arrest records guide names each one); each keeps the records of its own arrests.
Together, the three agencies in Macon County with all twelve months of 2025 on file reported 4,153 arrests to the FBI that year; how each case ended is in the court file, not in the arresting agency's.
The agencies and their counts, year by year, are in Macon County arrest records.
The Crimes Behind the Records: Macon County in 2025

An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
