Police say that the events started about six months before, when the previous maid left, claiming the house was haunted. At the end of March, Mr.Gruger told friends of footprints in the snow leading to his farm but not away, footsteps, and a strange newspaper. None of this was reported to the police.
Sometime on March 31, The oldest four Grubers were lured to the barn and killed, the younger Cazilia, surviving a short time. The Killer(s?) went into the house where they killed the toddler and the maid. Their task completed, they took care of the farm animals, ate the family’s food over the weekend.
The family was found on April 4th, 1922, when no one was seen in a couple days.
Autopsies concluded the family was killed using a mattock, a hammer-like tool similar to a pickax, one side of the head flattened into a hoe.
.Rbbery was considered motive at first, until the police found a large sum in plain sight.Then Viktoria’s husband, Karl Gabriel was a suspect, he was dropped after his surviving unit confirmed they saw him die in ww1.(His body was never found though)In 2007 Police academy students came up with a suspect but have kept it uner wraps out of respect to the killer’s family.
