Bret Baier reports on the mysterious disappearance of retired Air Force Major General William McCasland, who vanished from his Albuquerque home two weeks ago. Authorities, including the FBI, are actively searching for the 68-year-old former military scientist with ties to the UFO community. His wife, Susan McCasland Wilkerson, humorously hypothesized aliens beamed him up to a mothership on Facebook, as no foul play is suspected.
