Three Illinois men were shot and killed Sunday night at Great Lakes Dragaway, 18411 1st St, Kenosha County Sheriff David Beth said. The calls for service first came in just after 7 p.m. Sunday. There is no suspect in custody, although law enforcement are seeking a black male in his mid-20s wearing jean shorts and a black hood, and he may have left the scene in a black vehicle, Beth said. "They have no idea what happened, what caused this," Beth said, after speaking with the friends of the victims. Two of the victims died at the scene, while a third died on the way to the hospital, according to Beth. Two of the victims were from Aurora, Ill., Beth said. The race track, which contains a quarter-mile-long drag strip, was hosting an event called Larry's Funfest Sunday. Ambulances were still entering into the facility as of 9 p.m. Steve Prince, of Milwaukee, was at the races with his grandmother Sunday and said he saw three people on the ground near police tape on his way out. Emergency crews were attending to one of the people, Prince said, but the other two were on the ground, lying still unattended.
