Finding Someone in Custody in Macon County
A person kept in custody after an arrest in Macon County is held at the county jail, run by the Macon County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Macon County Sheriff's Office at sheriff-macon-il.us/corrections (page title: Corrections | Macon County Sheriff), which answered when SearchSystems opened it on October 4, 2026.
That page is the office's jail information page rather than a roster.
