Criminal Cases in the Circuit Court of Monroe County
In Illinois the public criminal record is the court file. Criminal cases from Columbia are heard by the Circuit Court of Monroe County, which hears every civil, criminal, family, probate, traffic and juvenile case, and the file of each case is kept by the Circuit Clerk.
For Monroe County, SearchSystems opened and checked the court records page for the county at monroecountyil.gov/departments/circuit-clerk (page title: Circuit Clerk | Monroe County, IL), phone 618-939-8681, 100 S. Main St., Waterloo, IL 62298, Monday - Friday 8:00 a.m. - 4:30 p.m., 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 Columbia
The Monroe County Sheriff's Office and the agency that reports for Columbia (filed by the FBI as Columbia Police Department) keep the arrest records in and around Columbia: 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.
Together, the two agencies in Monroe County with all twelve months of 2024 on file reported 117 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 Columbia arrest records.
The State's Attorney for Monroe County

The Sex Offender Registry for Columbia
Registered sex offenders living in Columbia are listed on the Illinois Sex Offender Registry, run by the Illinois State Police at illinois.gov. The registry is public and can be searched online.
Registration itself is done in person with the local agency where the registrant lives: the sheriff's office, or the city police in a city with its own department.
Asking an Agency in Monroe County for a Record
An arrest report, a booking record or a local criminal history letter comes from the agency that holds it, not from the court.
Under the Illinois Freedom of Information Act a county office must answer a request within 5 business days, with one 5-day extension, and it may charge copying only after the first 50 pages.
