Williamson County Jail Inmate Search
Williamson County Inmate Search
Most local arrests end up at the Williamson County Jail, 404 N. Van Buren, Marion, IL 62959 (618-997-6541). To find someone, start with VINELink. VINELink tracks custody and sends alerts when the Sheriff's Office books someone. Booking at the county jail can lag; a Franklin County jail may have the person. Call 618-997-6541. The sections below run from the county jail to state and federal custody.
1. How do I search for an inmate?
- Open VINELink and type the full name.
- Try VINELink on the web or the VINELink app for iPhone or the VINELink app for Android.
- Still nothing? Call the Williamson County Sheriff's Office at 618-997-6541.
2. Will the county hold someone for ICE?
- ICE may send the Williamson County Jail a Form I-247A detainer.
- The Illinois TRUST Act (5 ILCS 805/15) stops this county from honoring the 48-hour hold.
- Agents may wait outside the County Jail.
- After an ICE arrest, use the ICE Online Detainee Locator System with the A-number of the detainee.
3. What about youth arrested in this county?
Youth stay off the roster (705 ILCS 405/1-7). A judge locally picks the juvenile detention center for detained youth. Call 618-997-6541 to learn about a detained child's hearing.

5. Are local mugshots public?
Illinois treats adult booking photos as public (5 ILCS 140/2.15). Ask the Williamson County Sheriff's Office with an Illinois Freedom of Information Act request, or call 618-997-6541. Youth photos and most U.S. Marshals Service photos are withheld (5 U.S.C. 552). ICE records for someone held by the Sheriff's Office go through the ICE FOIA request page and mention the county.
↑ Back to the question list6. What if someone from Williamson County faces federal charges?
The U.S. Marshals Service may hold federal defendants in county jails in this county. The Southern District of Illinois hears it at Melvin Price U.S. Courthouse, 750 Missouri Avenue, East St. Louis, IL 62201 (618-482-9371). Use VINELink before sentencing; the Federal Bureau of Prisons inmate locator after.
↑ Back to the question list7. Where do county prisoners go after sentencing?
Prison-bound inmates here go to Illinois Department of Corrections intake. Each transfer is on the Illinois Department of Corrections inmate search; our Illinois state prisons guide explains it.
↑ Back to the question list8. How does release work after an arrest?
Illinois ended cash bail in 2023 under the Pretrial Fairness Act, so there's no money to post in Williamson County (725 ILCS 5/110). Within 48 hours, release or detention is decided (725 ILCS 5/110-6.1). More: our bail and release page.
↑ Back to the question list9. Where else could someone arrested in Williamson County be held?

↑ Back to the question list10. What is the population of the county?
The county has about 67,225 residents (U.S. Census Bureau Vintage 2025 estimate, released 2026). Marion, IL is the county seat.
↑ Back to the question list11. Is there a Williamson County warrant?
Williamson County's sheriff answers at 618-997-6541; Johnston City, Energy and the Crab Orchard area all get warrant service from deputies, who will tell callers whether one is active. The Williamson case on the statewide re:SearchIL case portal is the other check. Counsel can make that check, and a self-represented party can once the clerk adds their email. A Herrin or Marion attorney can go with you when you turn yourself in at the county jail at a set time, which judges tend to view favorably. Missed hearings get rescheduled by the clerk in Suite 100, 200 W. Jefferson Street, Marion, IL 62959, at 618-997-1301.
