Before the Hinterkaifeck murders, the family noticed warning signs they couldn’t explain: footsteps overhead, a newspaper no one ordered, and tracks in the snow that led to the house but never away. What followed was a crime so unsettling it still has investigators, historians, and true crime fans asking the same question over 100 years later: who or what was inside that farmhouse?

This is the case of Andreas Gruber, Cäzilia Gruber, Viktoria Gabriel, Cäzilia, Josef and Maria Baumgartner.
