The Hinterkaifeck Murders

In March 1922, six people were murdered on an isolated Bavarian farm. The killer stayed for four days, fed the livestock, ate from the pantry, and walked away without a trace. The Hinterkaifeck murders remain Germany's most haunting unsolved case, and more than a century later, no one has ever been charged. This episode covers the chilling weeks before the attack, the catastrophic failures of the investigation, and the four competing theories that each explain everything and prove nothing.
