A few days prior to the crime, farmer Andreas Gruber told neighbours about discovering footprints in the snow leading from the edge of the forest to the farm, but none leading back. He also spoke about hearing footsteps in the attic and finding an unfamiliar newspaper on the farm. Furthermore, the house keys went missing several days before the murders, but none of this was reported to the police.
Six months earlier, the previous maid had left the farm, claiming that it was haunted; the new maid, Maria Baumgartner, arrived on the farm on 31 March, only a few hours before her death.
Exactly what happened on that Friday evening cannot be said for certain. It is believed that the older couple, as well as their daughter Viktoria and her daughter Cäzilia, were somehow all lured into the barn one by one, where they were killed. The perpetrator(s) then went into the house where they killed two-year-old Josef who was sleeping in his cot in his mother’s bedroom, as well as the maid, Maria Baumgartner, in her bed-chamber.
On the following Tuesday, the 4th of April, some neighbours went to the farmstead because none of the inhabitants had been seen for several days, which was rather unusual. The postman had noticed that the mail from the previous Saturday was still where he had left it. Furthermore, young Cäzilia had not turned up for school on Monday, nor had she been there on Saturday.
