The vehicle, a Dodge Charger, was traveling “at a very high rate of speed” the wrong way northbound in a southbound lane in Chicago’s South Side around 5 p.m. Wednesday, Chicago Police Superintendent David Brown said at a news conference.By Thursday morning, 11 people still were in hospitals – six in fair condition, and five in good condition, police said.The Charger had been reported stolen in Markham, a southern suburb of Chicago, earlier Wednesday and a long rifle was found inside the vehicle, Brown said.“Obviously this is a horrible tragedy coming as it does on the eve of Thanksgiving,” Lightfoot said at the news conference following the crash.“When you’re going at that high rate of speed, anyone that you hit, whether it’s a car or a pedestrian, you significantly diminish their ability to survive.”Investigators are working to determine exactly how fast the Charger was traveling before the crash, Brown said."
