When the police officer arrives at the scene of the murder, he finds that the murderer is none other than the man who committed the murder in the previous scene. The police officer tries to convince the man that he is the murderer, but the man is adamant that he has nothing to do with the crime. The man tries to defend himself by pointing out that he was in the same room as the murderer at the previous murder scene. He also points out that the art teacher, who was also present at the murder scene, has gone to the first-aid room, but there is no one there to help him.
