Rasputin, Russian mystic healer, was killed by cyanide poisoning, beating, execution blank range, and finally thrown into an icy river. His autopsy revealed that it was the river that killed him.
In the evening when the murder was committed, he was first served cake and wine poisoned with cyanide. The only effect was to make him feel tired & gloomy. He was then shot point blank and thrown into the frozen Neva river.
Four days later, the autopsy of the body showed that he was shot three times. In the neck, heart and head,and had water in the lungs! This means that he was still breathing at the time of being thrown into the river.
Several legends still remain about this mysterious character.
