Chicago Police Deputy Chief Fred Milian said it was “another tragic incident.” Washington Park is home to the UniverSoul Circus, but there was no show Tuesday night. There is a performance, according to the official website, scheduled for 7pm on Thursday. “The circus was not operating today. And this had nothing to do with the circus. If the circus was operating, there would be more security there,” Melean said. Copyright © 2022 WLS-TV. All rights reserved.
