Yoo Young-chul (; born 18 April 1970) is a South Korean serial killer, sex offender, and self-confessed cannibal. After he admitted to the murders of multiple people, mostly prostitutes and wealthy old women, the Seoul Central District Court convicted him of 20 murders, although one case was dismissed when it was identified as being committed by another serial killer, Jeong Nam-gyu. Yoo burned three and mutilated at least 11 of his victims and admitted that he ate the livers of some of them. He committed his crimes between September 2003 to July 2004 and was apprehended on 15 July 2004. 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." Biography Yoo was married in 1992 and had one son. Yoo was previously convicted 14 times for several different charges, and served a total of seven years in prison prior to his string of murders. Serial murders From September to November 2003, Yoo killed several wealthy senior citizens by breaking into their houses and bludgeoning them with a hammer. To cover his tracks, Yoo made the scenes of his crime look like a robbery-homicide took place. However, no money was taken, which confused the police investigators. When the investigation started to intensify, Yoo switched to targeting female masseuses. In January 2004, Yoo was briefly arrested on a minor theft charge, but was released two days later. Starting in March 2004, Yoo called sex workers to his residence in western Seoul and bludgeoned them after having sex with them. His victims were dismembered and mutilated to hinder their identification. They were buried in the mountains surrounding the city. Police recovered 11 bodies from the mountain behind Bongwon Temple after Yoo's arrest. During initial interrogations, Yoo confessed to killing 19 people. On July 18, 2004, he admitted to an additional murder: the killing of a 44-year-old male street vendor. Yoo eventually confessed to killing 26 individuals on July 19, 2004, several days after his arrest, although no details were given. The list of purported victims included several individuals that did not match his prior pattern of wealthy seniors or masseuses. Friends of two of the masseuse victims, whose bodies had been recovered, claimed they were not involved in massage therapy, meaning that Yoo could have other, unreported victims. Although the "Rainy Thursday" murderer was active contemporaneously starting in April
