Finding Someone in Custody in Linn County
A person kept in custody after an arrest in Linn County is held at the county jail, run by the Linn County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Linn County Sheriff's Office at linncosomo.gov/inmate-roster (page title: Inmate Roster | Linn County Missouri Sheriff's Office), phone (660) 385-2062, 101 E. Washington Street Macon, MO 63552, 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.
