Finding Someone in Custody in Shasta County
A person kept in custody after an arrest in Shasta County is held at the county jail, run by the Shasta County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Shasta County Sheriff's Office at shastacounty.gov/sheriff/page/incustody (page title: In Custody | Shasta County CA), a site that blocks automated checks (HTTP 403), so open it in a browser.
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.
