Check VINELink while the case is open, and the Federal Bureau of Prisons inmate locator after sentencing.
↑ Back to the question list5. Can I get a booking photo?
Illinois treats adult booking photos as public (5 ILCS 140/2.15). Ask the Warren County Sheriff's Office with an Illinois Freedom of Information Act request, or call 309-734-8505.

Prison-bound inmates here go to Illinois Department of Corrections intake. For moves, use the Illinois Department of Corrections inmate search; see our Illinois state prisons guide.
↑ Back to the question list7. Will this county hold someone for ICE?
- ICE can ask Warren County to hold someone with a Form I-247A.
- The Illinois TRUST Act (5 ILCS 805/15) stops this county from honoring the 48-hour hold.
