Finding Someone in Custody in Washington County
A person kept in custody after an arrest in Washington County is held at the county jail, run by the Washington County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Washington County Sheriff's Office at news.washeriff.net/divisions/bookings (page title: Bookings | WCSO), which answered when SearchSystems opened it on October 4, 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.
