Dog the Bounty Hunter arrived at Brian Laundrie’s parents’ home Saturday, knocked on the door and met silence – but he’s already picked up a scent. The reality TV star and legendary bounty hunter, whose real name is Duane Chapman, is a father of 13 and lost a daughter around the same age as Gabby Petito in a car accident in 2006. He was already in Florida on a honeymoon with his wife Francie Chapman, he said, when people began reaching out to him to look into Laundrie’s disappearance.
