A 65-year-old man shot an Amazon driver after the two tussled in a dispute over a handicapped parking spot outside a Target Store on Tuesday.

The injured man, 21, was taken to a hospital, where he was in critical but stable condition with a gunshot wound to the back, according to St. Charles Police Lt. Tom Wilkison.

The dispute began just before noon outside the store at 3881 Mexico Road, Wilkison said. The Amazon driver had illegally parked his delivery van in a handicapped-accessible parking spot and was talking to the driver of a different Amazon van.

That's when a St. Charles man confronted them about the parking spot, Wilkison said. It wasn't clear if he had a disability.
