Finding Someone in Custody in Winfield
A person kept in custody after an arrest in Winfield is held at the county jail, run by the Cowley County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Cowley County Sheriff's Office at cowleycountyks.gov/Archive.aspx?AMID=41 (page title: Archive Center, Sheriff | Inmate Rosters), which answered when SearchSystems opened it on October 2, 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.
