This is a private reference site, not a Warren County office. We cannot confirm custody, release a person, post bond, or retrieve an official booking record. Contact the public office that holds the record.
Warren County Contact Routes
The Warren County Sheriff's Office is at 121 North A Street, Monmouth, IL 61462. Call sheriff administration at 309-734-8506 or the Warren County Jail at 309-734-8505. Non-emergency dispatch is 309-734-8383, and emergencies go to 911. The county does not publish separate booking-record desk hours or a photo-unit line. Use administration or the jail number to ask for the correct custodian, and check the official sheriff page before visiting.
Written requests through the sheriff's FOIA route may be sent by mail, fax, email, or delivered in person. Put “FOIA” in the email subject, describe the records precisely, and place an electronic request fully in the email body rather than in an attachment or link. The official page says a standard form is available but not required. It also asks whether inspection, electronic copies, or paper copies are wanted.
Choose the route that matches the record and custody stage:
- For a county booking sheet or releasable photo, begin with the Warren County arrest hub, then submit a focused sheriff FOIA request if needed.
- For current local custody, call the Warren County Jail. No confirmed official public county roster was found.
- For a recent Monmouth police arrest, consult the weekly police arrest reports, then request the city report or county booking record from its proper custodian.
- For custody or release alerts, search Illinois VINE. A missing result still requires confirmation with the holding agency.
- For a filed criminal case or disposition, contact the Warren County Circuit Clerk at 100 W. Broadway, Monmouth, during its posted weekday hours.
- For a person serving an Illinois prison sentence, use Illinois Department of Corrections. Federal BOP and ICE locators cover different custody systems.
