Montgomery County Inmate Population

Montgomery County inmate population records are managed by the Montgomery County Sheriff's Office in Hillsboro, Illinois. The county jail holds people arrested locally while they wait for court dates or serve short sentences. With around 28,400 residents, Montgomery County sits in south-central Illinois and processes a steady flow of bookings each year. This page explains how to find inmates in Montgomery County, request records through FOIA, and use state tools to look up people sent to prison. Whether you need to check on someone in the local jail or track a state inmate from this area, the steps are laid out below.

Montgomery County Jail Inmate Population

The Montgomery County Sheriff's Office operates the jail in Hillsboro. This is the main holding facility for anyone arrested within county lines. Pre-trial detainees and people serving sentences under one year stay here. The jail is not large. Montgomery County does not see the volume of arrests you find in Cook County or the collar counties, but it stays active enough that the roster changes from week to week.

To find out if someone is in the Montgomery County jail, call the sheriff's office. They can look up an inmate by name or booking number. Staff will tell you if the person is in custody, what charges they face, and the bond amount. Have the full name ready when you call. A date of birth helps narrow things down if the name is common. Most calls are handled during regular business hours, Monday through Friday. After hours, a deputy on duty may be able to help, but response times vary.

Montgomery County does not run a public online jail roster at this time. Some counties in Illinois post their bookings on a website, but that is not standard here. The phone remains your best option for a quick check. If you need detailed records, you will want to file a formal request (covered in the FOIA section below).

Keep in mind that newly arrested individuals may not appear in jail records right away. Booking takes time. There is usually a delay of several hours before all the paperwork is done and the person shows up in the system.

State Prison Inmate Population Search

People convicted of felonies in Montgomery County who get sentenced to more than one year in prison go to the Illinois Department of Corrections. IDOC runs all state prisons. You can search for anyone in state custody through the IDOC Inmate Search tool. It is free. Enter a last name, IDOC number, or date of birth to pull up results.

The IDOC website shows details for each person in the state system. Results include the inmate's current facility, offense, sentence length, and projected release date. Montgomery County cases that resulted in state prison time will show up here. IDOC houses roughly 28,900 inmates across its facilities statewide. The database is updated regularly as inmates get transferred, released, or reclassified.

Illinois law under 730 ILCS 5/3-5-1 requires IDOC to maintain master record files on every committed person. These files include basic identification data, sentence information, and facility assignments. While the full master record is confidential, the search tool gives the public enough to confirm if someone is in state custody and where they are held.

From the IDOC site you can also find visiting schedules, facility addresses, and instructions for sending mail to inmates. This is the starting point for any state-level search connected to Montgomery County.

Inmate Population Records and FOIA

The Illinois Freedom of Information Act at 5 ILCS 140 gives you the right to request public records from any government body in the state. This includes the Montgomery County Sheriff's Office. You can ask for booking logs, daily jail population counts, inmate rosters, and similar data. Put your request in writing. State that you are filing under the Freedom of Information Act. Be clear about exactly what records you want.

Montgomery County must respond within five business days. They can extend by five more days with a written notice explaining the delay. The first 50 pages of records are free. After that, they can charge the actual cost of copying. You can send your request by mail, email, or hand-deliver it to the sheriff's office in Hillsboro. Keep a copy of your request for your own records.

Some records are exempt. Medical files, mental health evaluations, and disciplinary reports for inmates are confidential and need a court order. Under 5 ILCS 140/2.15, arrest reports and basic booking information are generally available to the public. But if a case involves a juvenile or certain sensitive circumstances, parts of the record may be redacted. Most people looking for Montgomery County inmate population data will have no trouble getting what they need through a simple FOIA request.

For state-level IDOC records, file a separate request through the IDOC FOIA page. IDOC handles their own requests independently from the county.

Visiting Inmates in Montgomery County

The Montgomery County jail in Hillsboro allows visits during set hours. Call the sheriff's office to confirm the current schedule before you go. Bring a valid photo ID. Do not bring phones, bags, or anything else into the visiting area. Follow every posted rule. Staff can refuse entry to anyone who does not comply. Children may visit but typically need to be with an adult on the approved list.

For inmates who have been transferred from Montgomery County to a state prison, visitation rules fall under IDOC. You must get on the inmate's approved visitor list first. Each IDOC facility has its own schedule and its own set of rules. Call the lockdown hotline at (877) 840-3220 before you drive out. Lockdowns happen without warning and will cancel all visits for the day. Bring two forms of ID when visiting a state facility. Plan to arrive early since check-in can take time.
