Finding Someone in Custody in Farmington
The county jail, run by the San Juan County Sheriff's Office, holds everyone kept in custody after an arrest in Farmington, from every agency.
SearchSystems opened and checked the custody page of the San Juan County Sheriff's Office at sanjuansheriff.org (page title: About San Juan County Sheriff and Jail Inmate Locator), 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.
