Finding Someone in Custody in Lewistown
A person kept in custody after an arrest in Lewistown is held at the county jail, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the sheriff's office at mifflincountypa.gov/correctional-facility/inmate-lookup (page title: Mifflin County | Inmate Lookup), which answered when SearchSystems opened it on September 23, 2026.
Someone booked recently shows on that page; someone cited and released at the scene, or held a few hours at a city station, does not.
