Criminal Cases in the Circuit Court of Madison County
In Illinois the public criminal record is the court file. Criminal cases from Troy are heard by the Circuit Court of Madison 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 Madison County, SearchSystems opened and checked the court records page for the county at madisoncountyil.gov/departments/circuit_clerk/court_records_search.php (page title: Madison County Illinois Circuit Clerk Records Search), phone (800) 250-9884, 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 Troy
The Madison County Sheriff's Office and the agency that reports for Troy (filed by the FBI as Troy Police Department) keep the arrest records in and around Troy: 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 these agencies in Madison County: Norfolk Southern Railway in Madison County and Terminal Railroad Association (other agency); Southern Illinois University at Edwardsville (campus police); each keeps the records of its own arrests.
The Pierron Police Department and the Fairmont City Police Department are each listed by the FBI across several counties including Madison County, so their arrests are not broken out for Madison County here.
Together, the 20 agencies in Madison County with all twelve months of 2025 on file reported 8,317 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 Troy arrest records.
The Crimes Behind the Records: Troy in 2025
The agency that reports for Troy had 1 violent and 52 property crimes reported for 2025; each one is a report on file with it, and each arrest that follows is the start of a criminal record.
The Sex Offender Registry for Troy
Registered sex offenders living in Troy 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 Madison 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. The county records request page SearchSystems verified is at madisoncountyil.gov/departments/circuit_clerk/coppy_request.php (page title: Madison County Illinois Circuit Clerk Copy Requests).
