SearchSystems opened and checked the jail page of the Crook County Sheriff's Office at crookcountyor.gov/1249/Sheriff (page title: Sheriff | Crook County, OR), phone 541-447-6398, 260 NW 2nd Street, Suite 100 Prineville, OR 97754, Monday through Friday 8:00 am to 5:00 pm, which answered when SearchSystems opened it on September 24, 2026.
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 541-447-6398.
