Finding Someone in Custody in Morgan County
A person kept in custody after an arrest in Morgan County is held at the county jail, run by the Morgan County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Morgan County Sheriff's Office at ilsheriff.org/county/morgan (page title: Morgan County | Illinois Sheriffs' Association), phone (217) 753-2372, 300 West Court, Jacksonville, IL 62650, a site that blocks automated checks (HTTP 403), so open it in a browser.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at (217) 753-2372.
