In 2015, YouTube myth hunter ulown00b formulated a theory regarding the house in Blueberry that is sealed by the police for an unknown reason but it is most likely a murder scene. A demon's face can be found adjacent to the house. During the investigation the player found out that the pedestrian commonly reported as the Cane Killer appears to randomly spawn around the house, making him a prime suspect. Moreover, according to a bizarre claim, the cane killer's chest has a Piggsy like texture drawn which relates the incident to Piggsy as well, but upon technical analysis, it's just an optical illusion. All the theories describing the Cane Killer being the murderer are false.
