The Hwaseong Serial Murders: An Overview

The Hwaseong serial murders are a grim chapter in South Korea's criminal history.

Between 1986 and 1991, ten women were brutally murdered in the rural city of Hwaseong. The victims ranged in age from 14 to 71, reflecting a chilling disregard for human life.


The murders were characterized by a distinct pattern. The victims were typically strangled with their own clothes, often a pair of stockings. Evidence of sexual assault was also found in most cases.

The killer seemed to strike at random, with no clear connection between the victims. This randomness added an extra layer of fear and uncertainty to the case.

The Hwaseong serial murders were unprecedented in South Korea. The sheer number of victims and the brutal nature of the crimes shocked the nation.

The case also posed a significant challenge for the Korean National Police Agency. At the time, the concept of a serial killer was relatively unknown in South Korea.

The key events of the Hwaseong serial murders are as follows:

  • September 15, 1986: The first victim, a 71-year-old woman, is found strangled and sexually assaulted.

  • June 27, 1987: The second victim, a 25-year-old woman, is found with similar injuries.

  • July 27, 1987: The third victim, a 25-year-old woman, is found strangled with her own stockings.

  • December 12, 1987: The fourth victim, a 23-year-old woman, is found with similar injuries.

  • January 10, 1988: The fifth victim, a 19-year-old woman, is found strangled and sexually assaulted.

  • May 2, 1988: The sixth victim, a 29-year-old woman, is found with similar injuries.

  • September 7, 1988: The seventh victim, a 54-year-old woman, is found strangled with her own stockings.

  • September 16, 1988: The eighth victim, a 14-year-old girl, is found with similar injuries.

  • April 3, 1991: The tenth and final victim, a 69-year-old woman, is found with similar injuries.

Despite the best efforts of the police, the case remained unsolved for over three decades. It was only in 2019, with the advent of advanced DNA technology, that the killer was finally identified as Lee Choon-jae.

Who is Lee Choon-jae?

Lee Choon-jae was born in 1963 in the city of Hwaseong, South Korea. He lived a seemingly ordinary life, working as a repairman and living with his wife and two children.


However, beneath this facade of normalcy, Lee harbored a dark secret. He was the man responsible for the Hwaseong serial murders, one of the most notorious crime sprees in South Korean history.

Lee's crimes were not limited to Hwaseong. He confessed to several other murders and rapes, bringing his total number of victims to at least 15. His reign of terror spanned over a decade, from the mid-1980s to the late 1990s.

Despite his horrific crimes, Lee managed to evade capture for over three decades. He was finally arrested in 2019, after advances in DNA technology linked him to the Hwaseong murders.

Lee's story is a chilling reminder of the capacity for evil that can lurk beneath the surface of ordinary life. His case has left a lasting impact on South Korean society and continues to be studied by criminologists and psychologists around the world.

Timeline of the Hwaseong Murders

The Hwaseong serial murders began in 1986. The first victim was a 71-year-old woman, found strangled and sexually assaulted in a field. This marked the beginning of a terrifying crime spree that would last for five years.


Over this period, nine more women would fall victim to the same brutal pattern of violence. The victims ranged in age from teenagers to elderly women. All were strangled with their own clothing, and all showed signs of sexual assault.

The murders occurred at irregular intervals, making it difficult for police to predict when the killer would strike next. Despite the deployment of thousands of officers and the interrogation of countless suspects, the case remained unsolved.

The last known murder occurred in April 1991. The victim was a 69-year-old woman, killed in the same manner as the previous victims. After this, the murders abruptly stopped.

For years, the case went cold. The statute of limitations on the murders expired in 2006, meaning that even if the killer were caught, he could not be prosecuted for the crimes. However, the police continued to investigate, hoping to bring closure to the victims' families.

In 2019, a breakthrough finally came. Advances in DNA technology allowed investigators to link Lee Choon-jae to the murders. Confronted with this evidence, Lee confessed to the Hwaseong murders, as well as several other crimes.

Lee's confession brought an end to one of South Korea's most infamous cold cases. However, the impact of the Hwaseong murders continues to be felt to this day. The case has left a lasting mark on South Korean society and has forever changed the way the country approaches criminal investigations.



The Investigation: Challenges and Breakthroughs

The investigation into the Hwaseong serial murders was one of the largest in South Korean history. At its peak, over two million police officers were involved, and over 21,000 suspects were interrogated. Despite these efforts, the case remained unsolved for decades.


One of the main challenges was the lack of advanced forensic technology at the time. DNA profiling, which is now a standard tool in criminal investigations, was not available. This made it difficult to conclusively link the crimes to a single perpetrator.

The police also faced criticism for their handling of the case. There were allegations of tunnel vision, with investigators focusing on certain suspects to the exclusion of others. This, combined with the pressure to solve the case, led to several false confessions.

Despite these challenges, the investigators never gave up. They preserved the evidence from the crime scenes, hoping that advances in technology would eventually allow them to identify the killer.

Their persistence paid off in 2019, when a breakthrough finally came. Using modern DNA analysis techniques, investigators were able to link Lee Choon-jae to the murders. Confronted with this evidence, Lee confessed to the crimes.

This marked a significant turning point in the case. It demonstrated the importance of preserving evidence in long-unsolved cases and highlighted the potential of DNA technology in solving cold cases.

However, the resolution of the case also raised questions about the initial investigation. The fact that Lee was not identified as a suspect until decades after the murders prompted a re-evaluation of police investigation techniques.

The Hwaseong serial murders case serves as a stark reminder of the challenges faced by law enforcement in solving complex murder cases. It underscores the importance of persistence, the potential of technology, and the need for effective investigative techniques.

The case also highlights the profound impact that such crimes can have on society. The fear and uncertainty that gripped Hwaseong during the years of the murders have left a lasting mark on the community. The resolution of the case, while bringing closure, also serves as a reminder of the dark chapter in the city's history.



The Role of DNA Evidence in Cracking the Case

The Hwaseong serial murders case is a testament to the power of DNA evidence in solving crimes. For over three decades, the case remained unsolved, with the killer's identity a mystery. However, advances in DNA technology eventually led to a breakthrough.


At the time of the murders, DNA profiling was not yet a standard tool in criminal investigations. The technology was in its infancy, and its potential was not fully understood. As a result, the investigators were unable to link the crimes to a single perpetrator using DNA evidence.

However, they had the foresight to preserve the evidence from the crime scenes. This included items that the killer had left behind, which contained traces of his DNA. These items were stored for years, waiting for the day when technology would catch up.

That day came in 2019, when advances in DNA analysis techniques allowed investigators to extract and analyze the DNA from the preserved evidence. The results were conclusive: the DNA matched that of Lee Choon-jae, a man who was already serving a life sentence for a separate crime.

Confronted with this evidence, Lee confessed to the murders. The DNA evidence was the key that unlocked the case, proving beyond doubt that Lee was the killer. It demonstrated the potential of DNA technology in solving cold cases and brought closure to one of South Korea's most infamous murder cases.

Lee Choon-jae's Confession and Its Aftermath

The breakthrough in the Hwaseong serial murders case came in 2019, when DNA evidence linked Lee Choon-jae to the crimes. Confronted with this irrefutable evidence, Lee confessed to the murders. His confession marked a turning point in the case, bringing an end to over three decades of uncertainty.


Lee's confession was detailed and chilling. He admitted to killing ten women in Hwaseong between 1986 and 1991. He also confessed to several other crimes, including rapes and additional murders. His confession provided a horrifying glimpse into the mind of a serial killer.

The confession had a profound impact on the victims' families. For them, it brought a sense of closure, albeit a painful one. They finally knew the truth about what had happened to their loved ones, and the man responsible was already behind bars.

However, Lee's confession also raised questions about the death penalty. At the time of his confession, Lee was already serving a life sentence for a separate crime. This sparked a debate about whether he should be executed for his crimes, a question that remains unresolved.

The aftermath of Lee's confession also saw a re-evaluation of police investigation techniques in South Korea. The case highlighted the importance of preserving evidence in long-unsolved cases and the potential of DNA technology in solving such cases. It served as a reminder of the importance of meticulous police work and the potential for justice, even in cases that seem unsolvable.

Psychological Profile of a Serial Killer: Understanding Lee Choon-jae

Understanding the mindset of a serial killer is a complex task. It requires delving into the darkest corners of human psychology. In the case of Lee Choon-jae, experts have attempted to construct a psychological profile to shed light on his heinous crimes.


Lee's crimes were characterized by a pattern of sexual assault and strangulation. This suggests a need for power and control, common traits among serial killers. His victims ranged in age from teenagers to women in their 70s, indicating a lack of a specific victim type, which is unusual in serial killer cases.

Lee's confession revealed a chilling lack of remorse. He described his crimes in a matter-of-fact manner, showing no empathy for his victims. This lack of empathy is a key characteristic of psychopathy, a personality disorder often associated with serial killers.

However, constructing a psychological profile is not an exact science. It can provide insights into a killer's motivations and behavior, but it cannot fully explain why someone would commit such horrific crimes. In Lee's case, his motives remain a subject of speculation and study.

Understanding the psychology of serial killers like Lee Choon-jae is crucial for law enforcement and criminology. It can help in the identification and apprehension of future offenders. But it also serves as a stark reminder of the depths of human depravity.

The Impact on South Korean Society and Law Enforcement

The Hwaseong serial murders had a profound impact on South Korean society. The case gripped the nation for over three decades, becoming a symbol of fear and a source of public outrage.


The case exposed the limitations of the police force at the time. Despite a massive investigation involving thousands of officers and tens of thousands of suspects, the killer remained at large for years. This led to widespread criticism and a loss of public trust in the police.

In response, South Korean law enforcement underwent significant changes. There was a shift towards more scientific methods of investigation, including the use of DNA profiling. The case also highlighted the importance of preserving evidence, even in long-unsolved cases.

The Hwaseong murders also had a lasting impact on the legal system. The case prompted a re-evaluation of the statute of limitations for murder, which was eventually abolished in 2015. This allowed for Lee Choon-jae's crimes to be linked to him, even though they had been committed decades earlier.

The legacy of the Hwaseong serial murders continues to shape South Korean society and law enforcement. The case serves as a reminder of the importance of justice for victims and the need for constant evolution in crime detection and prevention strategies.
