In March 1922, a horrific event shook a small village in Bavaria, Germany, At an isolated farm named Hinterkaifeck, six people including an elderly couple, their widowed daughter, her two small children, and a newly hired maid were brutally killed with a sharp farming tool. Days before the crime, strange things began to happen around the house.
The farmer, Andreas Gruber, noticed footsteps in the snow leading from the dark forest directly to his house, but there were no tracks going back. The family also heard scary noises coming from the attic, and house keys suddenly went missing. Even their previous maid had left her job because she believed the house was haunted by spirits. On the night of the attack, the killer lured four family members into the farm barn one by one and killed them. Then, the killer walked inside the house and killed the innocent maid and the sleeping two year old baby.
What makes this story even more shocking is that the killer stayed inside the house for several days after committing the crime. Neighbors noticed smoke coming out of the chimney, and the farm animals were properly fed. The killer ate food from the kitchen while the six bodies lay cold. Police questioned over one hundred people, but no one was ever arrested. Was it a local neighbor with a grudge, or a dangerous stranger hiding in the attic? Over a hundred years have passed, yet the terrifying mystery of who killed the Gruber family remains unsolved.
