When Schlittenbauer and his friends came to investigate, they had to break a gate to enter the barn because all of the doors were locked. However, immediately after finding the four bodies in the barn, Schlittenbauer apparently unlocked the front door with a key and (suspiciously) entered the house alone.[3] A key to the house had gone missing several days before the murders, though it is also possible that Schlittenbauer, as a neighbor or as Viktoria's potential lover, might have been given a key.
