C.J. Spiller's step-grandfather reportedly has been identified as the gunman who killed two men and injured two others before committing suicide this morning in Union County, Florida.
The ABC affiliate in Gainesville, Fla., reported Union County Sheriff Jerry Whitehead has announced Hubert Allen Jr. went to his former place of employment, Pritchett Trucking, and shot an employee.
Allen then reportedly went to the family farm of company owner Marvin Pritchett, killed him and a farmhand and shot another man before returning home to kill himself.
Spiller is with the Bills for this afternoon's preseason exhibition against Washington at FedEx Field. Spiller started the game.
