Look Up Jefferson County Jail Inmates

Jefferson County Jail Roster Overview

The Jefferson County Sheriff's Office runs the county jail at the Jefferson County Justice Center in Mt. Vernon. Unlike a typical roster page, the sheriff's official inmate-search page does not list detainees on the web. It tells the public to download the Jefferson County Sheriff IL app to view inmates booked into the correctional facility. The published page content actively points to the app, so this is the official lookup channel, not a missing table. Research did not find a stated refresh rate or a retention window for released detainees, so this page does not promise real-time updates or claim how long a name stays listed.

The county roster covers people held locally, mostly pretrial detainees and short-term inmates, plus contract holds for outside agencies. It does not cover sentenced state prisoners, who move to an Illinois Department of Corrections facility, and it does not cover federal or immigration detainees, who appear in federal systems. When the app cannot find a person, the right move depends on which custody system actually holds them.

How to Use the Jefferson County Inmate Roster

The fastest path to Jefferson County jail inmate records is the sheriff app. The official inmate page links the app download and tells users to search the app stores by name. Booking may not appear instantly after an arrest, so allow time and use the jail phone if a match is unclear.

1. Install the Jefferson County Sheriff IL app from the App Store or Google Play, or open the official app share page.
2. Open the Inmate Search or Jail Info feature inside the app.
3. Search for the person by name and review the booked detainees the app lists.
4. If the app shows no match, call the jail at 618-244-8015 to confirm custody.

The official inmate-search page itself, shown below, is the source for the app-only instruction. It is worth seeing because it explains why a normal web roster search does not exist for this county.

As the page makes clear, the app is the documented way to view the inmate list, which is why the steps above begin with installing it rather than opening a website.

Jefferson County Roster Search Channels

Because the roster is app-directed, the public web does not expose a set of search fields to fill in. Rather than invent field labels, the table records what each documented channel accepts. The app holds the live list, while the other channels are fallbacks for records and identifiers.

The Android listing for the app, shown below, advertises the inmate search and jail-info features that the county relies on instead of a web roster.

The listing confirms the app handles inmate lookups, so installing it is the documented first step rather than an optional extra.

What a Jefferson County Inmate Profile Shows

No public web sample of a Jefferson County jail profile was available during research, so each field below is marked by how well it is supported. The app advertises an inmate search that shows booked detainees and arrest information. The mail rules confirm an inmate ID is used. Beyond that, the public web does not verify a mugshot, bond, or housing display, so this page does not claim those appear.

For booking photos specifically, the records-request route and what state law allows are covered on the Jefferson County jail mugshots page.

Finding County, State, and Federal Inmates

The county roster is only one of several systems, and using the wrong one wastes time. Pretrial and short-sentence inmates sit in the county jail and are found through the sheriff app. Sentenced felons move to an Illinois Department of Corrections prison and are found through the statewide locator. Federal and immigration detainees use separate federal systems. The 2024 jail inspection confirms the county jail also holds U.S. Marshals detainees under contract, so a federal case can sit inside a local cell.

For release and transfer alerts across these systems, register with Illinois VINELink rather than checking each one by hand.

What to Do If the App Shows No Match

An app-only roster fails some readers, and that is normal. A booking may not have posted yet, the name may be spelled differently, the person may have been released, or they may be held for another agency. Work through the channels in order rather than assuming the person is not in custody.

• Just arrested in Jefferson County: wait a few hours, then recheck the app or call the jail at 618-244-8015.
• Arrested by Mount Vernon Police: still check the sheriff app, since there is no separate city jail roster.
• Has a court case but is not in the app: search Judici or call the Circuit Clerk.
• Sentenced to prison: search the IDOC locator instead of the county app.
• Need an old booking report or photo: file a GovQuest records request with the sheriff.

The portal also tracks a filed request by its request number and key, which matters for anonymous requesters who have no account dashboard. For a release alert instead of repeated checks, register the person in Illinois VINELink.

Jefferson County Jail Facilities

Two facilities in the county hold inmates, but only one is the sheriff-run jail. The Justice Center handles local and contract detainees. Big Muddy River Correctional Center is a state prison and uses the IDOC locator instead of the county roster. Each facility has its own page with full lookup and visitation detail.

Booking Process in Jefferson County

When a person is arrested and accepted at the Justice Center, booking begins. The 2024 jail inspection describes a booking area with three holding rooms and updated intake equipment, including a Live Scan fingerprint machine, a body scanner, and a metal detector. A typical path runs from identity and warrant checks to a property inventory, a search and screening, a booking photo and fingerprints, medical and mental-health screening, and finally classification and housing. A booking may not show in the app the moment it happens, so allow time before assuming the person is not there.

After booking, Illinois law requires a first appearance before a judge without unnecessary delay under 725 ILCS 5/109-1. Since the Pretrial Fairness Act took effect on September 18, 2023, money bail is no longer the normal release path in new Illinois cases. The court now decides release conditions or detention, which is why a person can stay in custody even when the jail's own bonding page still lists fees.

Visitation Hours and Rules

Jefferson County jail visitation runs every day in blocks, with breaks at meal times. The sheriff page lists open visiting from 8 a.m. to 11 a.m., 1 p.m. to 5 p.m., and 6:30 p.m. to 8 p.m., with no visits during lunch and dinner. On-site visits must be scheduled at least one day ahead by calling 1-866-340-7879, and off-site video visits run through JailATM. Visitors need valid photo ID, must be 18 or older to visit alone, and may not bring food, drinks, phones, or purses into the visit area.

Note: people incarcerated at the facility within the past 90 days, and victims of the detainee, are not allowed to visit that detainee.

How to Contact a Jefferson County Inmate

Mail to a Jefferson County detainee is split by type. Ordinary letters from family or friends are no longer delivered as paper. They are sent electronically through InmateSales or mailed to a scanning address: Jefferson County Jail (IL), inmate ID and full name, P.O. Box 16060, Jonesboro, AR 72401. The original is scanned and destroyed. Legal mail still goes directly to the jail at 911 Casey Ave, but it must come from a legal authority such as an attorney's office. Books and publications are no longer accepted and will be destroyed, and blank paper, stamps, and envelopes are not allowed.

Because every mail and money item needs the inmate ID, families often need that number first. The sheriff mail page points to InmateSales to look up an inmate ID. Electronic messages and photos can be sent through JailATM under the same content rules.

Commissary and Inmate Funds

Money for a detainee's commissary account can be added three ways. JailATM takes online deposits at jailatm.com, a kiosk in the main lobby of the Justice Center takes in-person deposits, and a money order can be mailed directly to the jail. Checks are not accepted, and a mailed money order should include the detainee name and number. The official sheriff pages do not publish the vendor fees for these methods, so this page does not list a fee amount.
