Description:
Scp-3648 is a voice in a cave near London in the U.K. The voice tells you to jump in the water. The voice tends to coax 9/10 people into the water in which they will be assumed death by drowning. Among further testing with a camera the bodies are nowhere to be found. Also the voice only convinces people in this pattern, a male, a female, then a male and female at the same time, then repeat. The voice had moved since the last place it was. The voice moves quickly and far places whenever it moves. The voice is told to be a dead man's spirit that wants revenge for his mother’s death. The man’s mother was told to be killed by a male and female. They were a couple that were cold blooded killers, they both had killed 5 other people, all males in their mid 40’s. Then as the killers tried to kill their sixth man a mother intervened, breaking a killers forearm and shattering another’s spine. The mother died from a bullet to the head out of a m9 beretta by the female killer. The female and the male both died of blood loss and the mothers son went out for revenge of his mother's death. He thoughts were “if my mother didn’t try to save that person she could’ve seen everything I’ve done.” The man went on a killing spree. He killed 23 people and got held up in a cave. The police confirmed that he jumped in the water and his body was never recovered.
