Due to advancements in DNA technology, a 33-year-long murder mystery has finally been solved. The most infamous serial killing case in South Korea, otherwise known as the Hwaseong murders (1986-1991), resulted in the death of 10 women and girls. The true killer, Lee Chun-jae (pictured below), admitted to 30 rapes and 14 murders, 9 of which were part of the Hwaseong murder cases.

What instigated the confession was a recent discovery in DNA restoration technology. This new forensic advancement has allowed police and other government agencies to identify DNA that either could not be identified at the time it was processed or even after long periods of time, as in this case. The South Korean Police conducted a comparison between samples of DNA from a victim’s underwear with the DNA database of prisoners at the penitentiary. The outcome identified Lee as the culprit, who was already facing a life sentence for the last 2 decades for his sister-in-law’s rape and murder. He told the court that he “was surprised he wasn’t caught earlier,” (CNN). Lee also told reporters that he did not try to hide his crimes. Though detectives asked him questions, they were always about other people. The DNA results also confirmed the innocence of the man arrested for Lee’s crimes.
In 2008, a person named Yoon, whose full name cannot be released for legal reasons, was freed after spending 20 years in prison for the rape and murder of a 13-year-old girl, a murder victim from the Hwaseong cases. Last year, the DNA evidence was released, thus confirming Yoon’s innocence. Yoon was granted a retrial, and his lawyers are currently in the process of overturning his conviction. He told CNN, “I want to clear my false accusation, and I want my honor back.”

Suffice it to say, at the time of the murders, there were some discrepancies in the investigation. The Gyeonggi Nambu Provincial Police Agency Chief, Bae Yong-ju, admitted to ABC News that Yoon was mistreated by the police to the point where he made a false confession under coercion. The police involved in the case have issued a public apology to Lee Chun-jae’s victims, their families, and Yoon, a victim of the failed police investigation. Yoon, outraged from being subjected to years of injustice, aspires to continue his life as a free and innocent man.
So, what happens next? Lee Chun-jae will not be facing prosecution for the Hwaseong murders. The statute of limitations on the case has expired. However, he will continue to live out the rest of his life in prison for the rape and murder of his sister-in-law. Thanks to advances in DNA technology, grave mistakes, like those found in this case, will hopefully be reduced.
