Yoo Young-chul
Yoo Young-chul (born April 18, 1970) is a South Korean serial killer and self-confessed cannibal. Although he admitted to murdering 21 people, mostly prostitutes and wealthy old men, the Seoul Central District Court convicted him of 20 murders (one case was dismissed on a technicality). Yoo burned three and mutilated at least 11 of his victims, admitting he ate the livers of some of them. He committed his crimes between September 2003 and July 2004, when he was arrested. Yoo explained his motives in front of a TV camera saying "Women shouldn't be sluts, and the rich should know what they've done."
