Finding Someone in Custody in La Crosse County
The county jail, run by the La Crosse County Sheriff's Office, holds everyone kept in custody after an arrest in La Crosse County, from every agency.
SearchSystems opened and checked the custody page of the La Crosse County Sheriff's Office at lacrossecounty.org/sheriff/sheriff/inmate (page title: Inmate Locator | Sheriff | La Crosse County), a site that blocks automated checks (HTTP 403), so open it in a browser.
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.
