Finding Someone in Custody in Latah County
A person kept in custody after an arrest in Latah County is held at the county jail, run by the Latah County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the jail page of the Latah County Sheriff's Office at latahcountyid.gov/sheriff/detention (page title: Detention), phone 866-516-0115, Wednesday from 6:30 to 9:00 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 866-516-0115.
