2. Richard Chase
An American serial killer, Richard is remembered as one of the serial killers of the world. He had a feeling that the Nazis would turn his blood into powder by poison and as a result he thought of running short of blood. This prompted him to start killing people by shooting them and have sex with the dead bodies before bathing with the resulting blood pool. He was later charged of these crimes and got sentenced to gas chambers. In 1980, he was found dead after allegedly committed suicide.
