A quadruple amputee and professional athlete is facing a murder charge after he allegedly shot a man in his car during an argument.

Dayton Webber, 27, was driving the vehicle when he opened fire on the front-seat passenger in the town of La Plata, Maryland, at the weekend before dumping his body, say investigators.

Police said they were told about the killing of Bradrick Wells, 27, by other passengers in the car who had refused to help Webber get rid of the body.

Webber was arrested hours later across state lines in Charlottesville, Virginia. He was the first quadruple amputee to compete in the American Cornhole League, a game where players toss bean bags into a hole on a board.

He now faces charges including first-degree murder, say officials.
