Find Inmates at the Monroe County Jail

Monroe County Jail Overview

The Monroe County Jail is operated by the Monroe County Sheriff's Department at 225 E. 3rd Street in Waterloo, the county seat. It is a county jail, not a state prison, so the people held here are local adult detainees. Most are awaiting court or serving short sentences, not long felony terms. The sheriff's correctional division manages and supervises those in custody and lists programs that include education, substance-abuse treatment, mental-health services, and religious support.

The facility was built in 1986 and is small by Illinois standards. The 2024 state inspection recorded 18 double cells plus a few single and double detention rooms. Jail leadership in that report includes Captain Chad Mueller as superintendent and Sergeant Logan Zirkelbach in jail operations. Because the jail has only a few dozen beds, transfers and overflow can matter more here than at a large facility.

Monroe County Jail Capacity and Population

The clearest numbers come from the annual state jail inspection. On September 13, 2024, inspectors counted 34 people in a jail rated for 42 beds, which is about 81 percent of capacity. These are single-day counts, not yearly averages, and the county does not publish an average daily population.

Across recent inspections the count rose from 27 in 2022 to 32 in 2023 to 34 in 2024, while listed capacity slipped from 46 beds to 42. The 2024 report also noted that uniforms, shoes, towels, mattresses, and blankets had been purchased since the prior visit. None of the recent snapshots showed the jail over capacity.

How to Look Up an Inmate at the Monroe County Jail

No public online roster was located for this jail, so use the county jail channels rather than a search box. Have the person's full name ready, plus a date of birth or arrest date if you have it. The steps below move from the fastest check to the formal records request.

1. Call the jail and sheriff's department at 618-939-8651 and ask whether the person is in custody and what can be shared.
2. Check the Monroe County Sheriff Illinois app, which the department promotes for jail information.
3. Search the court file on Judici once charges are filed, to confirm a case and the next court date.
4. File a written county records request for a booking sheet or older record.

If the person was sentenced to prison, switch to the state locator, since this jail no longer holds them after transfer. The full workflow and the record fields are on the Monroe County jail inmate records page.

Monroe County Jail Address and Contact

The jail and the sheriff's department share the same Waterloo address. The sheriff does not publish a lobby-hours table, so call before visiting for property, records, or visitation timing. Custody operations run around the clock for law enforcement, but public lobby services may be limited.

Jail operations contacts in the sheriff's correctional division include Captain Chad Mueller at extension 258 and Sergeant Logan Zirkelbach at extension 538, both reached through the main line.

Visiting Someone at the Monroe County Jail

The jail offers video visits, scheduled through a vendor named InmateSales. The sheriff's visitation page does not post a fixed day-and-time schedule, so create an account, check availability, and call the jail if the system does not show open slots. Visits are recorded and monitored, and visitation is a privilege that can be limited for discipline, security, or threat reasons.

Note: avoid carrying purses, cases, or strollers into the secure area, since the jail does not publish locker availability.

Mail, Phone, and Money at the Monroe County Jail

The jail uses two mailing addresses, and mail sent to the wrong one is rejected. Standard non-legal mail goes to a scanning vendor at a Kentucky post office box. Legal mail and money orders go to the physical jail in Waterloo. Every incoming letter needs the inmate's name and inmate ID plus a return address, so call for the inmate ID before mailing.

Mail must be letter size and no thicker than light card stock so it can feed through a scanner. Pictures are the only enclosure allowed, up to 10 per package on photo paper. Stamps, cash, checks, stickers, homemade or musical cards, and non-white paper are barred, and non-compliant mail is destroyed rather than returned.

Medical Care, Property, and Programs

Medical care is handled by Advanced Correctional Healthcare. Detainees request care at a kiosk in the recreation area or in soft holding, and in an emergency they notify a corrections officer right away. Required medical fees are deducted from the detainee's account.

Property rules are narrow. Only white T-shirts, white socks, white underwear, and white long johns can be dropped off, all new and in original packaging. Personal property is returned at release, and unclaimed property is destroyed 60 days after release. For a person transferred to state or federal custody, the inmate may approve someone to collect property, who must come to the jail to claim it.

The Sheriff and Correctional Division

The jail is run by the Monroe County Sheriff's Department, led by Sheriff Neal Rohlfing, who has held the office since 2014. The department's correctional division is responsible for the care, custody, and supervision of people held in the jail, along with courthouse security and dispatch. The division states that it works to keep safe and secure conditions for both detainees and staff and offers programs aimed at reentry.

For a family, the useful takeaway is that one small department handles intake, records routing, and custody here. That is why a phone call to the main line often does more than searching the website, and why a written records request goes through the county rather than a dedicated jail records portal. The court side, the charges that follow a booking, is handled separately and is covered on the court records after a jail arrest page.

Booking and Intake at the Monroe County Jail

Monroe County does not publish a step-by-step booking page, so intake follows Illinois jail standards plus the jail's service pages. After an arrest, deputies or another agency bring the person to the jail. Intake includes a legality-of-confinement check, a search, identity verification, fingerprints, and a photograph taken under current law. Seriously ill or injured people get a medical look before they are held, and notices of rights and jail rules are posted in the receiving area.

After booking, the court decides charges and release. Since Illinois ended cash bail in September 2023, release turns on court-ordered conditions and detention decisions rather than a set payment. A new booking will not appear on any public web roster, so confirm custody by phone or through a records request.

About the Monroe County Jail

The jail sits in the county-government core of Waterloo, near the courthouse, Circuit Clerk, and State's Attorney at 100 S. Main Street. The Illinois Department of Corrections inspects the jail every year and posts the reports for public review, which is the best public source on conditions here. The 2023 report flagged a narrow supervision-check timing issue and recommended bringing checks in line with standards. The 2024 report noted purchases of basic supplies and clothing. No litigation, consent decree, or death-in-custody report was located in the official sources, so those should not be assumed. Monroe County was founded in 1816 and sits about 11 miles southeast of St. Louis along the Mississippi River, which keeps the jail close to a major metro area while serving a county of roughly 35,000 residents.
