Williams is wanted in connection with the shooting death of Tyrone Hardin, at a Canadian National railyard in Harvey on Saturday.

Police said Williams stole a car from a woman at a gas station Saturday afternoon at 159th and Halsted, and crashed less than a mile away as officers gave chase. He then allegedly ran under a viaduct, and up on the CN Railway tracks and into the nearby railyard, where he encountered Hardin and shot the guard in the stomach.

Williams also allegedly shot at someone else before stealing Hardin’s car and fleeing the scene.

Investigators said witnesses reported hearing more than a dozen shots when Hardin was killed.
