Illinois State Police said about 1:45 a.m., Mr. Kief was driving east on Interstate 72 at White Heath Road when his vehicle ran off the road and overturned, ejecting him. He was not wearing a seatbelt.

A 23-year-old man from Bolingbrook, whose name was not released, was riding with him and was taken to an area hospital.
