Strange Occurrences Before the Murders

In the days leading up to the murders, Andreas Gruber reported strange occurrences around the farm. He told neighbors about hearing footsteps in the attic and finding an unfamiliar newspaper on the property. Additionally, keys to the house went missing, and there were signs of someone trying to break in.

Despite these unsettling events, the family did not report anything to the police. This decision proved fatal as the intruder—or intruders—struck with lethal force. The signs of a mysterious presence added a chilling layer to the Hinterkaifeck Murders, suggesting the killer had been stalking the family.

The Unsolved Investigation

The investigation into the Hinterkaifeck Murders was extensive, but it failed to identify the killer. Police questioned numerous suspects, including neighbors, former lovers, and even vagrants passing through the area. However, they could not gather enough evidence to charge anyone.

Investigators found that the killer had stayed on the farm for several days after the murders. They discovered that food had been eaten from the kitchen, and the livestock had been fed. This behavior suggested that the murderer was comfortable on the property and possibly knew the family. Despite these clues, the case grew cold.

Theories and Suspects

Over the years, various theories have emerged about who committed the Hinterkaifeck Murders. One popular theory involves Lorenz Schlittenbauer, a neighbor who was romantically linked to Viktoria. He discovered the bodies and acted suspiciously during the investigation. Some believe he had a motive related to a rumored paternity dispute over Josef.

Another theory suggests that Viktoria’s husband, believed to have died in World War I, may have returned seeking revenge. However, no concrete evidence supports this idea.
