Finding Someone in Custody in Liberty Lake
The county jail, run by the Spokane County Sheriff's Office, holds everyone kept in custody after an arrest in Liberty Lake, from every agency.
SearchSystems opened and checked the custody page of the Spokane County Sheriff's Office at spokanecounty.gov/359/Booking-Classification (page title: Booking & Classification | Spokane County, WA), phone 509-477-2278, 1100 W. Mallon Avenue Spokane, WA 99260, 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.
The Spokane County Jail by the Numbers
