I was doing paperwork at the station when I received a call about a disturbance. Upon arriving at the old man's house, the narrator seemed anxious but claimed the old man had simply died of natural causes. However, during questioning the narrator's story fell apart and he confessed to killing the old man out of paranoia. I arrested the narrator for murder at the scene and he was charged. After the arrest, an autopsy confirmed the cause of death was not natural.
