Finding Someone in Custody in Frio County
A person kept in custody after an arrest in Frio County is held at the county jail, run by the Frio County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Frio County Sheriff's Office at co.frio.tx.us/page/co.sheriff (page title: Sheriff's Office | Frio County, TX), phone 830-505-7153, which answered when SearchSystems opened it on September 23, 2026.
That page is the office's jail information page rather than a roster, so a search for a particular person goes through the office at 830-505-7153.
