Finding Someone in Custody in Pierce County
The county jail, run by the Pierce County Sheriff's Office, holds everyone kept in custody after an arrest in Pierce County, from every agency.
SearchSystems opened and checked the custody page of the Pierce County Sheriff's Office at co.pierce.wi.us/departments/sheriff_s_office/jail_roster.php (page title: Pierce County, WI), 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.
