Finding Someone in Custody in Johnson County
A person kept in custody after an arrest in Johnson County is held at the county jail, run by the Johnson County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Johnson County Sheriff's Office at jocogov.org/johnson-county-sheriff/public-information/inmate-search (page title: Inmate Search | Johnson County Kansas), 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.
