Finding Someone in Custody in Post Falls
The county jail, run by the Kootenai County Sheriff's Office, holds everyone kept in custody after an arrest in Post Falls, from every agency.
SearchSystems opened and checked the custody page of the Kootenai County Sheriff's Office at kcsheriff.com/169/In-Custody-Report (page title: In-Custody Report | Kootenai County Sheriff, ID), which answered when SearchSystems opened it on September 24, 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.
