Finding Someone in Custody in Wildomar
The county jail, run by the Riverside County Sheriff's Office, holds everyone kept in custody after an arrest in Wildomar, from every agency.
SearchSystems opened and checked the custody page of the Riverside County Sheriff's Office at riversidesheriff.org/213/Inmate-Information (page title: Inmate Information | Riverside County Sheriff, CA), 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.
