The Hinterkaifeck Murders: The Unsolved Mystery of the Gruber Family Massacre
In 1922, the quiet Hinterkaifeck farm in rural Germany became the site of one of history’s most baffling unsolved crimes. Six members of the Gruber family and their maid were brutally murdered, leaving behind a trail of eerie clues and unanswered questions. Decades later, the Hinterkaifeck murders remain a haunting enigma.
The Gruber Family and Hinterkaifeck Farm
The Hinterkaifeck farm was home to a reclusive family led by Andreas Gruber and his wife, Cäzilia. Their daughter, Viktoria Gruber, lived with them after her husband, Karl Gabriel, died in World War I. The household also included Viktoria’s two children, Cäzilia Gabriel (7) and Josef Gruber (2), whose paternity was disputed by neighbor Lorenz Schlittenbauer. The family’s live-in maid, Maria Baumgartner, joined just hours before the massacre.
Isolated from the nearby village of Gröbern, the Grubers were seen as odd but hardworking. Their farm’s remote location and strange occurrences—like unexplained noises in the attic—added to its eerie reputation.

Mysterious Signs at Hinterkaifeck Farm
Weeks before the murders, unsettling incidents occurred:
- Footprints in the Snow: Andreas found fresh tracks leading to the farm’s engine hut but none returning.
- Unexplained Magazine: A Munich-based magazine appeared on the property, unclaimed by neighbors or the mailman.
- Attic Noises: The former maid reported hearing footsteps and doors opening at midnight, prompting her to quit.
On March 31, 1922, Maria Baumgartner arrived for her first day of work. By morning, the entire household would be dead.

Discovery of the Hinterkaifeck Victims
When the Grubers missed church and local deliveries, neighbors grew suspicious. On April 4, Lorenz Schlittenbauer and others investigated:
- Barn Horror: Four bodies—Andreas, Cäzilia, Viktoria, and young Cäzilia—were found buried under hay, bludgeoned to death.
- House of Terror: Josef’s crushed skull was discovered in his crib, while Maria lay dead under a blanket.
The Murder Weapon and Crime Scene
The killer used a farming tool, likely a mattock or hoe, to deliver fatal blows. Victims showed blunt force trauma, except 7-year-old Cäzilia, who suffered a slit throat and self-inflicted scratches.
Autopsy Reports: Clues to the Hinterkaifeck Murders
Autopsies revealed:
- Blunt Force Injuries: Skull fractures from repeated strikes.
- Cäzilia’s Struggle: Throat cut, hair clutched in her hands, and defensive wounds.
- Timing: Cäzilia died 2–3 hours after others, suggesting prolonged suffering.
The killer likely stayed at the farm post-massacre, hiding bodies and burning evidence.
