Illinois treats adult booking photos as public (5 ILCS 140/2.15). Ask the sheriff's office with an Illinois Freedom of Information Act request, or call 815-319-6000. 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 list the arrest date.
↑ Back to the question list7. Where do local 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?
There's no cash bail locally: the Pretrial Fairness Act ended it in 2023. Within 48 hours, release or detention is decided (725 ILCS 5/110-6.1). More on our pretrial release guide.
↑ Back to the question list9. Will this county hold someone for ICE?
- ICE may send the jail a Form I-247A detainer.
- The Illinois TRUST Act (5 ILCS 805/15) stops this county from honoring the 48-hour hold.

↑ Back to the question list11. Winnebago County: is there a warrant?
Call the Winnebago County sheriff at 815-319-6000; its deputies work warrants from Roscoe to Pecatonica and can check a name for a warrant. Your case in the circuit clerk's FullCourt Enterprise search, the county's own stand-in for Illinois' statewide re:SearchIL e-records portal, will also show a warrant. A Rockford attorney can plan your voluntary surrender at the jail, so you walk in on a weekday instead of being booked late at night.
