Jeong Nam-gyu

On January 14, 2004, in Bucheon, Gyeonggi Province, he kidnapped, raped and then murdered two people. He then continued to murder people in Gyeonggi and Seoul, including the murder of a woman returning home late at night. He murdered mainly in the southern part of Seoul, including Shin-gil, Guro and Gwanak. His reason for killing a male elementary school student after sexually assaulting him was that he himself was abused by a man as a child. On April 26, 2006, he was arrested at the end of a fight in which he tried to kill a man and the man's father. Subsequent investigations revealed that he also murdered a man at Imun-dong. Before Jeong confessed this murder, serial killer Yoo Young-Chul falsely confessed that he also had committed it. On April 12, 2007, he was sentenced to death by the Supreme Court and detained in Seoul Detention Center. ==Suicide==

On the morning of November 21, 2009, a jail employee discovered Jeong had attempted to hang himself from a noose made from a plastic bag. He was rushed to the hospital, but died the following morning. His crimes were also depicted in 2022 South Korean drama Through the Darkness. == List of crimes ==
