Finding Someone in Custody in Minnehaha County
The county jail, run by the Minnehaha County Sheriff's Office, holds everyone kept in custody after an arrest in Minnehaha County, from every agency.
SearchSystems opened and checked the custody page of the Minnehaha County Sheriff's Office at web.minnehahacounty.gov/dept/so/jailInmateInfo/browseJailInmate.php (page title: Minnehaha County Who's Behind Bars), phone 605-367-4321, 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.
