An extensive search is underway for a cadet at West Point who has gone missing. The U.S. Military said the cadet, whom they identified only as a member of the Class of 2021, was last seen at the academy on Friday. He was scheduled to participate in a military skills competition this past weekend but failed to show up. Officials said Sunday the cadet's M4 rifle is also missing, but they don't believe he has any magazines or ammunition. They say he does not pose a threat to the public, but may be a danger to himself. Law enforcement agencies and emergency services, including the U.S. Coast Guard, are helping the military in their search, which has already spanned West Point's academic and athletic facilities as well as its cadet barracks.
