Sangamon County, Illinois, has about 194,000 residents (2024 Census Bureau estimate), and arrests there are reported to the FBI by the Sangamon County Sheriff's Office, 18 city agencies and six campus, state or other agencies. An arrest leaves the same records whoever makes it: the arresting agency's report, the record of anyone held at the county jail, and, if the State's Attorney files charges, a case in the Circuit Court of Sangamon County. This guide says who keeps each one, what it costs and who may see it, with the arrest counts each agency reported.
This guide covers who makes arrests, how many arrests, booking and the jail, finding an arrest, copies, cities and common questions.

Booking: Where People Arrested in Sangamon County Are Held
A person kept in custody after an arrest in Sangamon County is held at the county jail, whichever agency made the arrest, apart from the short stay some city departments' own holding cells allow; a person cited and released at the scene is not booked at all. The jail's record of each person held, with the charges, is a public record of the arrest, and the court file takes over from there.
On an average day in 2023 the jail held about 320 people, down from about 340 in 2019. Its rated capacity in 2023 was 314 beds, and it ran at 103 percent of it that year. The figures are from the Vera Institute of Justice's Incarceration Trends data.
SearchSystems opened and checked the custody page of the Sangamon County Sheriff's Office at sangamonil.gov/departments/s-z/sheriff/inmate-roster (page title: Inmate Roster), which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone who was booked recently; a person cited and released at the scene, or held only a few hours by a city department, will not be on it.
A sentence of more than a year is served in state prison; the Illinois Department of Corrections lists its inmates at idoc.illinois.gov/offender/inmatesearch.html.
How to Find Out About an Arrest in Sangamon County
An arrest in Sangamon County can be traced in three places, depending on where the case stands: the custody page of the Sangamon County Sheriff's Office described above, for anyone booked into the county jail; the case index of the Circuit Court of Sangamon County, which shows whether charges were filed and the next court date (the court records page SearchSystems verified is at sangamonil.gov/courts); the State's Attorney, which decides whether an arrest becomes a charge (its page is at sangamonil.gov/departments/s-z/state-s-attorney, phone (217) 753-6690).
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. That record shows what agencies reported to the state, which is wider than one county's court index but can lag it.
Getting a Copy of an Arrest Record in Sangamon County
The report of an arrest is released by the agency that made it; the jail and the court hold their own records of the same event, but not the report. Under the Illinois Freedom of Information Act the agency must answer within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
- An arrest by the Sangamon County Sheriff's Office: ask its records unit.
- An arrest in Springfield, Chatham, Sherman, Auburn, Rochester, Riverton or another of the cities listed above: the records unit of the agency that reports for that city.
- An arrest by the Springfield Park District, the Capitol Airport Authority or Lincoln Land Community College: the records office of the agency involved.
- A defendant who has been charged gets the report through the case: the State's Attorney, (217) 753-6690, handles discovery for pending cases.
- The court file of a case that was filed: the Circuit Court of Sangamon County, through the court records page at sangamonil.gov/courts.
- Any county record that is not posted: the county records request page SearchSystems verified is at sangamoncountycircuitclerk.org (page title: Sangamon County Records).
- Your own statewide record: a name-based or fingerprint-based request to the Illinois State Police.
