The Most Mysterious Unsolved Disappearances of All Time

Dennis Martin

Dennis Martin disappeared on a camping trip in the Great Smoky Mountains on June 14, 1969. Martin was a few days shy of his 7th birthday. At 4:30 p.m., Dennis and his friends planned to separate and sneak up on his family to scare them. They intended to leap out of the woods on both sides and frighten the adults. When the time came, the boys jumped out from one side, but Dennis never appeared on the other side of the woods.
