Finding Someone in Custody in San Benito
A person kept in custody after an arrest in San Benito is held at the county jail, run by the Cameron County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Cameron County Sheriff's Office at cameroncountytx.gov/incoming/inmates/site (page title: Cameron County Inmate List), 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.
