She said, 'This guy is critical, this is number one, call the cops,'" Dore said."I hope everyone is OK," Marz said. "Two of the guys that were down were responsive, that I saw.""I really feel for the guys that it happened to and they are just out on a Friday night going to the Hawks game," Dore added.A Chicago police investigation is ongoing.
