Four LSU football fans were beaten up Saturday in Morgantown, W.Va., after the Tigers defeated West Virginia University, a Morgantown police spokesman said.

Investigators do not know if the assault had anything to do with the football game or if the victims were targeted because they were LSU fans, 1st Sgt. Stephen Ford said.

The victims, three men and a pregnant woman, were attacked while trying to leave a parking area near the football stadium, Ford said.

Someone threw a rock through an open window of the victims’ vehicle, one of the victims got out and asked a group of people nearby what happened and a fight ensued, Ford said.

One of the male victims — Marcus Mason, 40, of Pittsburgh, Pa. — suffered serious injuries to his face and was taken to a local hospital, Ford said.

The other three victims suffered minor injuries.

Investigators have not made any arrests and do not have any suspects, Ford said.

By the time authorities arrived on scene, “everyone was gone,” he said.

Authorities with the West Virginia University Police Department are assisting with the investigation, Ford said.

Ed Preston, the university’s police chief, referred all questions to Ford.

Mason’s family declined comment.
