Excerpts from the DailyHerald.com:

A crash occurred about 12:30 a.m. Saturday morning in Wheeling when a vehicle traveling northbound on Wolf Road struck and crossed the raised concrete median. The vehicle entered the southbound lanes, left the road, and struck a parked unoccupied vehicle and tree in the 600 block of North Wolf Road. At some point after the impact, the vehicle ignited and became fully engulfed in flames. A single occupant was located in the left front seat who was unresponsive on scene and later transported to the Cook County Medical Examiner and pronounced dead.

Nobody else was injured and the investigation is ongoing.
