Andrew McGann, 28, is the accused "Monster of Devil’s Den," charged with the murder of two hikers in front of their children. McGann was arrested in the middle of getting a haircut. McGann is a school teacher with a history of creeping out parents and students. The manhunt began Saturday when two traumatized sisters aged 7 and 9 ran to a visitors center at the Devil’s Den State Park in Arkansas and told a horrifying story. State troopers found Clinton Brink and his wife Cristen stabbed to death.
