The Hinterkaifeck Murders: The Farm Where the Killer Lived in the Attic

In the spring of 1922, an entire family and their maid were slaughtered on a lonely Bavarian farmstead. In the days before, the old farmer had reported footprints in the snow that led to the house but never away, footsteps in the empty attic, and a face at the window. More than a century later, the Hinterkaifeck murders remain one of the most chilling unsolved cases in history.
