The Cobalt had burst into flames, and Missak started to walk toward the crash scene, then jumped a nearby barrier and ran west, prosecutors said. The two people from the Cobalt, Vanegas and her husband, were taken to Advocate Illinois Masonic Medical Center, where Vanegas, who had been the passenger, was pronounced dead at 7:39 a.m. and her husband, the driver, was treated for broken ribs, bruised lungs and a head contusion, prosecutors said.
