When asked by his companions why he had gone into the house alone when it was unclear if the murderer might still be there, Schlittenbauer allegedly stated that he went to look for his son Josef.

In 1971, a woman named Therese T. wrote a letter citing an event in her youth: At the age of 12, she witnessed her mother receiving a visit from the mother of the brothers Karl and Andreas S. The woman claimed that her sons from Sattelberg were the two murderers of Hinterkaifeck. The mother said, "Andreas regretted that he lost his penknife" in the course of
