Finding Someone in Custody in Weston County
A person kept in custody after an arrest in Weston County is held at the county jail, run by the Weston County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Weston County Sheriff's Office at westongov.com/county-sheriff/detention-center (page title: Detention Center | Weston County), 25 N. Sumner Ave. Newcastle, WY 82701, which answered when SearchSystems opened it on September 24, 2026.
That page is the office's jail information page rather than a roster.
