SearchSystems opened and checked the custody page of the DeKalb County Sheriff's Office at dekalbsheriff.com (page title: DeKalb County Jail, IN Inmate Roster, Booking, Arrests, Warrants), a site that blocks automated checks (HTTP 403), so open it in a browser.
Someone booked recently shows on that page; someone cited and released at the scene, or held a few hours at a city station, does not.
