Finding Someone in Custody in Warsaw
A person kept in custody after an arrest in Warsaw is held at the county jail, run by the Kosciusko County Sheriff's Office, whichever agency made the arrest.
SearchSystems opened and checked the custody page of the Kosciusko County Sheriff's Office at kosciuskosheriff.org/inmate-list (page title: Kosciusko County Inmate List, Indiana), phone (574) 267-5667, 221 W Main St, Warsaw, IN 46580, 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.

From the Jail to State Prison
