Finding Someone in Custody in San Jose
A person kept in custody after an arrest in San Jose is held at the county jail, run by the Santa Clara County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Santa Clara County Sheriff's Office at sheriff.santaclaracounty.gov/home (page title: Office of the Sheriff | County of Santa Clara), a site that blocks automated checks (HTTP 403), so open it in a browser.
That page is the office's jail information page rather than a roster.
