Nikolai Dzhumagaliev (Metal Fang)

Nikolai Dzhumagaliev (Metal Fang) is a Kazakhstani serial killer. 

Nikolai made it his mission to rid the world of prostitutes and killed seven women before he was caught. Also known as "Metal Fang" for his white metal teeth, he would lure women into the dark end of a local park, where he would rape them and hack them to death with an axe. 

He also practiced cannibalism; he cooked certain parts 

of his victims, eating some and even serving the rest to friends of his at get-togethers. He made a habit of preparing ethnic dishes out of his victims and serving them to his friends. His crimes were discovered when two drunks, whom he invited over to his house, discovered a woman's severed head in the kitchen. He was found not responsible for his murders (which are believed to be at least seven) due to insanity, and he was committed to a Tashkent mental institution.

He escaped in 1989 while being transported to another facility. He was re-captured in 1991 in Fergana. Dzhumagaliev is now jailed in the asylum.
