In March of 2012, an 18-year-old pre-med student returned to his hometown of Tupper Lake, New York, to enjoy spring break with his family and friends. But after heading off to a local party with some high school buddies, he vanished, and hasn’t been seen since. Despite only a couple of his belongings being found, there’s one theory that holds weight in this case, with the whole town apparently knowing who is behind this disappearance. This is the story of Colin Gillis.
