On the morning of June 5, 1960, a grim discovery was made along the shoreline of Lake Bodom in Espoo, Finland. Four local teens on a camping trip were found brutally bludgeoned and stabbed inside their tent, with three of them having succumbed to their injuries. The survivor, Nils Gustafsson, suffered a broken jaw and multiple facial fractures, leaving him with almost no memory of the incident. Yet, before long, the suspicion mounted, and many came to believe Gustafsson was actually the killer.

But did he really do it? Or was the real perpetrator one of several other shady men who came under police scrutiny in the aftermath of the crime? Either way, the case remains unsolved, and the murderer never saw justice.

Join host Ryan Kraus for a psychological exploration of evidence found at the scene in an attempt to finally uncover the truth of this baffling mystery.
