Finding Someone in Custody in Westmoreland County
A person kept in custody after an arrest in Westmoreland County is held at the county jail, run by the Westmoreland County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Westmoreland County Sheriff's Office at apps.westmorelandcountypa.gov/prison/PrisonInmates/PRISON_INMATES.ASP (page title: Westmoreland County Inmates), which answered when SearchSystems opened it on September 23, 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.
