Finding Someone in Custody in Madras
A person kept in custody after an arrest in Madras is held at the county jail, run by the Jefferson County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Jefferson County Sheriff's Office at jeffersoncountyor.gov/sheriff (page title: Jefferson County Sheriff's Office | OREGON | Jefferson County Oregon), phone 541-475-6520, 675 NW Cherry Lane Madras, OR 97741, 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, so a search for a particular person goes through the office at 541-475-6520.
