On a cold spring day in 1922, a remote farmstead in Germany became the scene of one of the most shocking and enduring unsolved crimes in history. Six people, including two children, were murdered with a brutal farming tool. The case became known as the Hinterkaifeck Murders—a mystery that, to this day, baffles investigators and true crime lovers alike.
This blog explores the facts, legends, and chilling details of this century-old horror.
A Quiet Farm in Bavaria
Hinterkaifeck was a small, secluded farm located roughly 70 km north of Munich, near the town of Gröbern. The Gruber family—Andreas, Cäzilia (his wife), their widowed daughter Viktoria, and her two children—lived there in relative isolation. Life was quiet, but underneath that rural peace, a disturbing tension brewed.
The Strange Signs Before the Slaughter
In the weeks leading up to the murders, several strange events were reported:
- Mysterious footprints in the snow led from the forest to the farm—but none led back.
- Andreas Gruber spoke of hearing footsteps in the attic.
- A newspaper unfamiliar to the family appeared inside their home.
- The former maid had quit, claiming the house was haunted.
These warning signs were unsettling but not enough to prompt serious action. Tragically, they were signs of an impending nightmare.
March 31, 1922 – A Night of Blood
The murders occurred sometime during the evening of March 31, 1922. One by one, four family members were lured to the barn and bludgeoned to death with a mattock (a tool similar to a pickaxe). The killer then entered the home and murdered 2-year-old Josef and the new maid Maria Baumgartner, who had only arrived that day.
There were no screams, no cries for help—just cold, calculated murder.
The Horrifying Discovery
For several days, the family was not seen in church or school. On April 4th, neighbors came to investigate. What they found shocked the village:
- The bodies of Andreas, Cäzilia Sr., Viktoria, and young Cäzilia lay stacked in the barn, covered in hay.
- Josef and Maria were found murdered inside the house.
What chilled investigators most was not just the brutality, but what came next…
The Victims
- Andreas Gruber (63) – A strict and often disliked man.
- Cäzilia Gruber (72) – His wife.
- Viktoria Gabriel (35) – Daughter, possibly abused.
- Cäzilia (7) – Viktoria’s daughter, found with clumps of hair in her hands.
- Josef (2) – Viktoria’s son, of disputed paternity.
- Maria Baumgartner (44) – Maid, tragically killed on her first day.
The Killer’s Chilling Presence After the Murders
The most disturbing detail? The killer stayed in the house.
- Animals were fed.
- Food was eaten.
- Smoke rose from the chimney.
It appeared the killer lived among the corpses for days, going about daily routines.
Investigation and Suspects
Despite multiple investigations, no one was ever charged. Over 100 suspects were questioned. Some of the key suspects included:
- Lorenz Schlittenbauer – A neighbor and Viktoria’s rumored lover.
- The Gump Brothers – Former soldiers with a violent past.
- Robbery gone wrong? – Unlikely, as valuables remained untouched.
Forensics at the time were primitive, and the crime scene was contaminated by curious villagers before police arrived.
Theories: Truth or Speculation?
Incest and Revenge
It was revealed that Viktoria and Andreas may have had an incestuous relationship. Josef’s real father was unknown, possibly leading to revenge by someone who believed they were the rightful father.
Hired Killer?
Some believed a professional killer was hired to eliminate the family due to land disputes or shame.
Supernatural?
The former maid believed the house was cursed. With all the odd events before the crime, some believe there’s more than meets the eye.
What Happened to Hinterkaifeck Farm?
The farmhouse was demolished in 1923, one year after the killings. Today, the site is empty except for a memorial cross.
A detailed 3D model and floor plan have been recreated by researcher C.S. Frank, helping modern theorists analyze what might have happened.
