On the morning of August 23, 2008, a local man goes for an ATV ride on his property in Happy Valley, Tennessee, located on the border of Great Smoky Mountains National Park.  When he failed to contact his family, the local authorities were notified, and a search kicked off.  Days later, close to the National Park border, his abandoned ATV was found under strange circumstances.  Join us this week as we investigate the puzzling disappearance of Mike Hearon.

June 14th, 1969. A young boy sets off on a camping trip with family in the Great Smoky Mountains. On the second day, a group of kids, including the young boy, decided to play a prank on the adults by hiding in the woods next to the campground. After less than five minutes, the group of kids returned but the boy was nowhere to be found. In the following weeks, the largest search and rescue operation in NPS history (to this day) failed to find any clues as to what happened. Join us this week as investigate the puzzling disappearance of Dennis Martin.
