(4/5) The family had stated before that they heard "strange noises" coming from their attic.

This case has been unsolved since then.

(3/5) -which was an attack on the Gruber family, located in Waidhofen, Bavaria, Germany. 6 people were murdered by an anonymous person/people (yes, they never found who it was).

The victims, (which I won't be naming to protect them) were murdered with a mattock, also known as a "grub axe."

To anyone wondering "wtf are the Hinterkaifeck Murders?", they were murders that took place in the evening of March 31st, 1922-
