Finding Someone in Custody in Cimarron County
The county jail, run by the Cimarron County Sheriff's Office, holds everyone kept in custody after an arrest in Cimarron County, from every agency.
SearchSystems opened and checked the custody page of the Cimarron County Sheriff's Office at cimarroncoso.gov/inmate-search (page title: Inmate Search | County Sheriff's Office), phone 877-654-8463, which answered when SearchSystems opened it on September 24, 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.
