Finding Someone in Custody in De Witt County
A person kept in custody after an arrest in De Witt County is held at the county jail, run by the DeWitt County Sheriff's Office, whichever agency made the arrest.

Washington St. Clinton, IL 61727, which answered when SearchSystems opened it on September 23, 2026.
That page is the place to look for someone booked recently. A person cited and released at the scene, or held only a few hours by a city department, will not be on it.
