CHICAGO (AP) — Police say a stray bullet killed a 68-year-old man as he drove on Chicago’s South Side.

They say the man was in a vehicle in the Bridgeport neighborhood around 6 p.m. Tuesday when gunfire pierced the rear window and struck him in the back of his head, police said. His vehicle then collided with a snowbank.

The Cook County Medical Examiner’s Office identified him as Alva Besst. It says he was rushed to a hospital in critical condition and pronounced dead a short time later.

Police say he was not the intended target of the shooting. No arrests have been made.
