The father and girlfriend of a U.S. Air Force airman accused of a deadly shooting at a Wal-Mart Supercenter in North Dakota early Tuesday are saying little about the man. Grand Forks police say 21-year-old Marcell Willis walked into the store and opened fire with a handgun, killing one worker and injuring a second before shooting himself.
