In his description, it was the murderer who killed all the people around the altar who believed in the evil god, and he was an innocent victim who was chosen by the evil god believers to be sacrificed to the evil god. Detective Carlin, who communicated with him, believed him. However, just when everything was going according to Langley's vision, the murderer he invented appeared. Intention: Believe in the beauty of the world
