Cold Cases The Strange Case

The Footprints at Hinterkaifeck

Before six people were killed on a remote Bavarian farm in 1922, the farmer found footprints in the snow leading to his house — and none leading away. The case was never solved.

Hinterkaifeck was not really a village. It was a single farmstead — a house and barn joined together — standing on its own near a forest in rural Bavaria, a little way from the hamlet of Kaifeck, between the towns of Ingolstadt and Schrobenhausen.

In the spring of 1922 it was home to six people: the farmer Andreas Gruber and his wife Cäzilia; their widowed daughter Viktoria Gabriel; Viktoria's two children, Cäzilia, aged seven, and Josef, aged two; and a new maid, Maria Baumgartner, who arrived on the last day of March.

She had been there only a few hours.

The warnings

What makes Hinterkaifeck so haunting is what happened before.

According to accounts given later by neighbours, in the days leading up to the killings Andreas Gruber told people about strange things on the farm. He had found footprints in the snow, leading from the edge of the forest to the farmhouse. There were none leading back.

He said he had heard footsteps in the attic. A set of house keys had gone missing. He had found a newspaper on the farm that nobody in the household had bought.

The family's previous maid had left months earlier. She was reported to have said that the house was haunted.

Footprints going in, and none coming out. And still, apparently, nobody called the police.

The discovery

The killings are believed to have happened on the evening of Friday 31 March 1922. Over the following days, people noticed that something was wrong. Little Cäzilia didn't come to school. The family missed church. The postman left mail.

On 4 April, men from the neighbourhood went to the farm and found the bodies: four in the barn and two inside the house.

And there was another unsettling detail. The farm's animals had been fed. Neighbours said they had seen smoke from the chimney during those days. Someone, it seemed, had stayed on at Hinterkaifeck after the crime.

The investigation

Robbery seemed unlikely: money was found in the house. Over the years, police questioned more than a hundred people. Suspects were considered and cleared; some were named in newspapers and by local gossip. Nothing was ever proven.

The farm was demolished in 1923. The victims' skulls were removed during the investigation, and some were reportedly shown to clairvoyants; they were lost, apparently during the Second World War.

FACT Established by documentary or physical evidence.

What's documented

The victims, the date, the discovery and the long, unsuccessful investigation are on record, along with the neighbours' accounts of what Andreas Gruber told them.

SPECULATION Possible, unproven, and labelled so you can enjoy it responsibly.

What's unknown

Who was in the attic, who made the footprints, and who killed the family — or whether those strange signs were related at all — has never been established.

In 2007, police students in Bavaria re-examined the case using modern methods. They reportedly reached a view on the most likely suspect, but chose not to publish a name, out of respect for living relatives and because there was no way left to prove it.

You learned this today!!! YOU LEARNED THIS TODAY !!!

  • Hinterkaifeck was a small farmstead in Bavaria, between Ingolstadt and Schrobenhausen.
  • On the evening of 31 March 1922, six people living there were killed, including two children and a maid who had arrived that very day.
  • In the days before, the farmer reportedly told neighbours about strange footprints in the snow, noises in the attic and missing house keys.
  • Evidence suggested someone stayed on the farm for days after the killings, feeding the animals.
  • Despite investigations lasting decades, the case was never solved. The farm was demolished in 1923.
