Finding Someone in Custody in Marshall County
The county jail, run by the Marshall County Sheriff's Office, holds everyone kept in custody after an arrest in Marshall County, from every agency.
SearchSystems opened and checked the custody page of the Marshall County Sheriff's Office at sheriffmarshallcounty.org/current-inmate-roster (page title: Private Site), which answered when SearchSystems opened it on October 9, 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.
