Finding Someone in Custody in Boone County
The county jail, run by the Boone County Sheriff's Office, holds everyone kept in custody after an arrest in Boone County, from every agency.
SearchSystems opened and checked the custody page of the Boone County Sheriff's Office at report.boonemo.gov/mrcjava/servlet/RMS01_MP.I00030s (page title: Current Detainees of Boone County Jail), phone (573) 875-1111, 2121 County Dr. Columbia, MO 65202, 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.
