Hwaseong serial murders
Police in South Korea receive confessions from convicted murderer Lee Chun-jae to the serial rapes and murders, which occurred between 1986 and 1991 and left at least nine dead. He denies a tenth murder, now believed to be perpetrated by a copycat. The investigations inspired the movie "Memories of Murder" and saw 21,000 people investigated. Lee, who is serving life for the 1994 rape and murder of his sister in law, cannot be prosecuted because the statute of limitations has expired. He had been linked to three victims earlier this month by DNA.
