Finding Someone in Custody in Forest County
A person kept in custody after an arrest in Forest County is held at the county jail, run by the Forest County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Forest County Sheriff's Office at forestcountysheriff.org/jail.html (page title: Forest County Sheriff's Department), phone 715-478-3331, which answered when SearchSystems opened it on September 23, 2026.
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 715-478-3331.
