The Hinterkaifeck Murders are an absolute fucking trip.
The typical horror cliches are all there: mysterious footprints, objects mysteriously appearing and disappearing, and a house that eerily went quiet for a few days before the neighbors found out what happened.
Hinterkaifeck was a farm that was on the outskirts of Kaifeck, Germany. The occupants were an old man named Andreas Gruber, his wife Cäzilia, their widow daughter Viktoria Gabriel, her kids Cäzilia (same name as her grandmother) and Josef, and their maid Maria Baumgartner who had just started working there on March 31st 1922.
Six months prior to the murder, the previous maid quit on grounds that she thought the house was haunted, supposedly hearing footsteps when nobody was home. In the weeks proceeding to the murder, Andreas claimed he found two people’s foot prints in the snow that started at the forest and went to the farmhouse, and once found a newspaper he had no recollection of buying. Additionally in the days before the murder a house key was said to have gone missing. The Gruber family were semi-pariahs in their community, with rumors (later confirmed by court records) that Andreas had an incestuous relationship with Viktoria, so many of these claims were just brushed off.
The first rumblings that something was wrong was that people showed up to the farmhouse but found it to be eerily quiet and empty; none of the family was out tending to the farm and the family dog was not seen running around. Additionally, the postman noted that mail had begun to pile up. The final warning sign was that little Cäzilia had not been at school in a few days.
Neighbors Lorenz Schlittenbauer, Jakob Sigl and Michael Pöll decided to investigate on April 4th, 1922. Finding all the doors locked, they decided to break in through the barn’s machine room. Inside the barn, they found a grisly sight: the four bodies of Andreas, Viktoria and the two Cäzilias were under a board covered with hay, found to have been killed systematically with blows to the head. After moving the bodies, Schlittenbauer produced a key (we’ll get to that later) that opened the door leading into the farmhouse, where in spite of the house’s quietness over the past few days appeared to have had recent activity in it. They then found the bodies of Maria and Josef, bludgeoned to death in their beds.
The investigation uncovered some grisly details. The Gruber family had been murdered on March 31st, but the presence of someone living in the house indicates that whoever killed the Gruber family had lived there for three days with the body. Additionally, utilizing early forensics the investigators established that each of the family members who were killed in the barn were led in there… one by one. Finally, evidence showed that the younger Cäzilia had been alive for several hours after the assault… tearing her hair out in tufts while lying in the straw.
There were initial problems in the investigation, one of which was no murder weapon had been found. The investigator determined the murder weapon was a pick mattock, which is a farming tool that is essentially a hybrid of a pickaxe and a hoe. Other witness reports came but for reasons unknown were not investigated. One witness report of note is three days before the bodies were discovered, artisan Michael Plöckl passed by Hinterkaifeck at night. Plöckl observed that the oven had been heated by someone, and that person had approached him with a lantern and blinded him, to which he sped up and kept walking. Plöckl also noticed that the smoke from the fireplace had a disgusting smell. Despite this grim testimony, no investigations were conducted to determine what had been burned that night in the oven.
There were two predominant murder suspects. The first was Karl Gabriel, the supposedly dead husband of Viktoria who had been said to have died in a shelling in World War I but whose body had never been recovered. After the murders, locals began to question if Karl had truly died, and was infuriated by claims that his son Josef was actually Andreas’, born out of incestuous rape. At the end of World War II, captives from the Schrobenhausen region who were released prematurely from Soviet captivity claimed that they had been sent home by a German-speaking Soviet officer who claimed to be the murderer of Hinterkaifeck. Some of these men later revised their statements, which diminishes their credibility, but it is noteworthy that Karl had expressed interest in moving to the Soviet Union. Additionally, old war buddies would later claim they saw Karl alive.
The second major suspect was Lorenz Schlittenbauer. Evidence included producing the house key during the murders after he supposedly could not get in any of the locked house doors, his claim during the initial investigation that Josef was his son, and disturbing the bodies, which would compromise a thorough investigation. Rumors circulated that Schlittenbauer had consistently pressed Viktoria for money, based on previous withdrawals she had made at the town bank. Later on in 1925, a local school teacher found Lorenz at the demolished farm, wherein he stated that the perpetrator's attempt to bury the family's remains in the barn had been hindered by the frozen ground. This was seen as evidence that Schlittenbauer had intimate knowledge of the conditions of the ground at the time of the murders, although being a neighbor and familiar with the local land, he may have been making an educated guess. Lorenz would ultimately become the local suspect, and later on successfully won libel suits against him stemming from this.
Overall, the police conducted over a hundred interviews but failed to make any conclusion or arrests. The murders faded from an active part of the community’s day to day life and into a tragic tale, and Hinterkaifeck was demolished. During the demolition, a discovery was made: the pick mattock that had been used to murder the occupants of the house.
It was found in the attic.
