Some of the biggest historical mysteries in South Korea involve unsolved crimes, lost treasures, and strange events that continue to baffle experts and locals alike.
Many people are drawn to chilling tales like the Hwaseong serial murders, which were only solved after decades. These murders have inspired changes in forensic science in Korea.
Other stories, such as mysterious outcomes of wars and ancient invasions, add layers of intrigue to Korean history.
Even today, new clues and questions arise about old cases. These mysteries feel alive and invite anyone interested in discovering what really happened in the past.
The Hwaseong Serial Murders
The Hwaseong serial murders are among the most famous criminal cases in South Korea. These murders left a deep mark on the country’s society and led to important changes in police work.
Overview of the Hwaseong Case
The Hwaseong serial murders took place between 1986 and 1991 in Hwaseong, a rural area near Seoul. During this period, ten women aged between 13 and 71 were found murdered.
Most of the victims were sexually assaulted and strangled. The killings happened at night and in quiet areas, causing fear in local communities.
Families became cautious about letting their loved ones walk home alone. Homes were locked tightly, and crime in rural areas became a major topic in the news.
The long investigation inspired the film Memories of Murder, which brought more attention to the case. Police searched for suspects using blood type and other clues, but the case stayed unsolved for decades.
Investigation Challenges
Police faced many problems while working on the Hwaseong murders. Technology at the time was limited.
DNA testing was not yet common, and forensic tools were basic. Officers gathered thousands of tips and checked the blood type of local men, but they could not match a suspect.
The killer avoided leaving clues. Multiple task forces worked on the case, and over two million police officers took part in the investigation.
Pressure from the media and public grew with each murder. Some people in South Korea lost trust in the police because they could not solve the case.
Mistakes happened during the investigation. Police mishandled tips and questioned some innocent suspects harshly.
As a result, finding the person responsible took longer and caused more pain for the victims’ families. Details about the case can be found in news accounts about the Hwaseong murders.
Lee Chun-jae and The Confession
Lee Chun-jae was eventually linked to the Hwaseong murders. He was already in prison for other crimes when new DNA technology connected him to several murders from the case.
Years later, police questioned Lee, and he confessed to the killings. He admitted to the Hwaseong murders and other violent crimes.
Lee’s confession finally gave answers to questions police had struggled with for years. Despite the confession and DNA match, Lee could not be prosecuted for most of the killings because the statute of limitations had expired.
He stayed behind bars for other crimes. More about Lee Chun-jae can be found on his biography page.
Impact on South Korea
The Hwaseong murders changed how South Korea approached criminal investigations. Police realized they needed better forensic tools, like DNA analysis, and more careful questioning of suspects.
The case pushed for updates in the law, including a longer statute of limitations for murder. Many people criticized how the investigation was handled, which led to more oversight of police work.
Victims’ families continued to search for justice and answers, even after Lee Chun-jae’s confession. The story of the murders also influenced pop culture.
Memories of Murder showed how terrifying the crimes were and brought the case to new audiences. Today, the Hwaseong murders are seen as a turning point in how South Korea handles crime and police accountability.

Baffling Disappearance Cases
South Korea has had several missing persons cases that continue to puzzle investigators. These incidents often involve limited evidence, making them difficult for police and leaving many families desperate for answers.
Vanishing of a Newlywed Couple
One of the most discussed disappearances involves a newlywed couple who went missing under unexplained circumstances. The couple had recently married, moved into their home, and were building their new life together.
Then, without warning, both vanished without leaving behind any clear clues. Neighbors reported seeing the couple return home one evening.
Their apartment was found undisturbed, with personal belongings and valuables left in place. There were no signs of forced entry or struggle.
Family and friends were left confused, as there was no history of conflict or financial problems that might explain their sudden disappearance. Despite extensive search efforts and media attention, little new information has surfaced.
The case remains unsolved and continues to raise questions about how two adults can vanish so completely. It is often listed among South Korea’s most mysterious unsolved cases, standing alongside others like the Frog Boys mystery.
Role of CCTV Footage
CCTV cameras play a huge role in solving many crime cases in South Korea. However, in the case of the missing newlywed couple, the lack of helpful footage only deepened the confusion.
Investigators found that the cameras near the couple’s apartment were either not working properly or did not capture anything unusual on the night they disappeared. Some recordings were missing or too blurry to identify anyone clearly.
Police believe that if foul play was involved, the perpetrator may have known about the camera positions or intentionally avoided them.
Importance of CCTV footage in missing person cases:
| Case | CCTV Footage Available | Helped Solve Case? |
|---|---|---|
| Newlywed Couple | No | No |
| Other crime cases in Korea | Yes (varies) | Sometimes |
These technical limits have become an important lesson for law enforcement. Better camera coverage and maintenance are now viewed as essential for preventing such disappearances in the future and aiding investigations into similar crime cases.
Enigmatic Homicides in Busan
Busan, South Korea’s second largest city, has a history of difficult-to-solve murder cases. These incidents have left many questions open for years and continue to attract attention from crime watchers and locals alike.
Unresolved Crime Cases
Busan has seen several unsolved homicides over the years. Each case generates concern not only about justice for victims but also about the safety of the city’s residents.
There have been cases where evidence pointed in multiple directions, making investigations long and difficult. While some crimes have been closed using DNA evidence or through confessions, many are still unresolved.
Limited technology in the past and the high crime rate in certain periods made it hard for investigators. Even though modern police in Busan now use advanced forensics, some older homicide cases remain in limbo.
The local community sometimes organizes memorials for victims of these lingering crimes. The cases are often featured in news stories and documentaries, keeping memories alive and pressure on authorities to revisit the files.
The Mashimaro Killer
One of the most talked-about mysteries in Busan is the story of the Mashimaro Killer. This nickname comes from the criminal’s habit of leaving behind items or drawings related to Mashimaro, a popular Korean cartoon rabbit.
The killer’s identity is still unknown, despite many police efforts. The linked crimes were chilling because they showed patterns that suggested careful planning.
Victims had certain characteristics in common, adding to the public’s fear. Police launched several investigations that used undercover work and neighborhood surveys, but they never found enough evidence to make an arrest.
This case stands out for its mix of clues and dead ends. The continued interest in the Mashimaro Killer has led to online discussions, documentaries, and even movies.
The case is often mentioned among the most chilling unsolved crimes in Korea.
Medical Mystery: The Han River Drowning
A young medical student’s death in the Han River sparked nationwide debate in South Korea. Conflicting reports, mystery around CCTV footage, and public suspicion have kept this case in the headlines.
Case Background
On April 30, 2021, the body of Sohn Jung-min, a 22-year-old medical student, was found in the Han River. He had been missing for six days after spending a late night at a riverside park with a friend.
Before his disappearance, people last saw Sohn asleep near the riverbank. His friend, who was with him that night, later became a focus of police questions and public scrutiny.
Sohn’s family raised concerns about the cause of death and possible foul play. They questioned whether it was truly an accident or if something more serious had happened.
Some believe police mishandling made things worse and caused trust issues in the investigation process. This case became one of the most talked-about unsolved crimes in Korea because so many details were left unexplained.
Notable Evidence
Authorities conducted an autopsy and reported that Sohn died from drowning. However, many in the public were not convinced.
Some people pointed out gaps or unclear parts in the available CCTV footage, raising more questions than answers about what really happened during the early hours next to the Han River. Sohn’s father filed criminal charges against his son’s friend, known as “Mr. A,” hoping to keep the investigation open.
Some key facts, like the time gaps and what happened right before Sohn disappeared, remain unclear. Lists of unanswered questions were widely shared online.
People wanted to know why certain evidence was missing and why the friend’s story seemed to change. The case is still remembered in South Korea as a mysterious tragedy with many loose ends.
Infamous Asphyxiation Cases
South Korea has faced several high-profile homicide cases involving asphyxiation. Some of these cases remain unsolved, leaving families and investigators searching for answers even today.
Unknown Motives
Some of the most chilling asphyxiation cases in South Korea feature unknown motives. Victims were sometimes found with no clear evidence of why they were targeted, and connections between the cases were hard to spot.
The infamous Hwaseong murders are one example. During the late 1980s and early 1990s, someone killed women through asphyxiation and left them in fields or near rice paddies.
Police struggled to find a logical link or motive tying the victims or crime scenes together. The killer chose random victims, which made it hard for investigators to predict his next move or identify a single suspect.
Even when police identified Lee Choon-jae as the criminal, his exact motives for many murders stayed unclear. Police often focused on possible connections like grudges or personal relationships, but these did not fit most of the crimes.
The randomness of the attacks spread fear, leading many to feel that anyone could become a victim in these unsolved cases. More details can be found on the Hwaseong murders and Lee Choon-jae.
Forensic Limitations
Forensic science in South Korea during the 1980s and 1990s was less advanced than today. Investigators could not use DNA analysis or genetic testing to identify suspects in asphyxiation homicides.
Blood type testing gave only limited leads. In the Hwaseong murder cases, police collected blood and fibers, but results mostly pointed to Type B blood, which was not specific enough to narrow down the suspects.
Police investigated over 21,000 people and compared them to the evidence. Many innocent people were questioned, but these efforts did not lead to results.
Fingerprint matching and other identification methods were also less reliable at the time. This lack of technology let the perpetrator commit multiple crimes without detection.
Only years later, updated DNA tools finally linked the real killer to these unsolved crimes.
The Role of Technology in Solving Mysteries
Modern technology has become a vital tool for investigators in South Korea. Its use has improved how crimes are solved and helped lower the crime rate by making it easier to track evidence and identify suspects.
Importance of CCTV Footage
CCTV footage has made a major impact on crime investigations in South Korea. Cameras are widely used in public areas, apartments, streets, and even parking lots.
These videos often provide real-time proof of someone’s actions, showing where suspects go and what they do before and after a crime. Police often use CCTV to confirm alibis and track persons of interest.
Footage might clearly show a suspect entering or leaving a crime scene. When combined with other evidence, this makes it easier to identify who is involved.
Having so many cameras has also made people feel safer. It discourages crime because potential criminals know they could be caught on video.
Families and communities appreciate the sense of security that comes from knowing help is just a camera away.
DNA and Blood Type Matching
DNA technology and blood type testing are critical in South Korean investigations. Test results help police connect suspects to crime scenes using tiny traces of evidence like hair, saliva, or blood.
Authorities use DNA and blood type analysis to match samples found at a scene with people suspected of involvement. In one notable case, DNA evidence was key to solving a decades-old serial murder mystery.
Blood type testing, while less precise than DNA, still helps in narrowing down possible suspects or ruling out others. These technologies are especially useful when other evidence is missing or unclear.
They have made it much harder for suspects to escape justice, since results can be very difficult to dispute in court.
Media Influence on South Korean Mysteries
South Korean media shapes how famous crime cases are understood. Movies, news, and TV impact public perception and keep interest in these mysteries alive.
Memories of Murder and Public Perception
The film Memories of Murder is based on the real-life Hwaseong serial murders. Its release in 2003 brought nationwide attention to these unsolved crimes.
The movie showed the brutality of the cases and the frustration of officers who could not solve them. After the film, more people in South Korea talked about the case.
Public interest led to new efforts by police to reopen investigations. Memories of Murder turned a local tragedy into a topic of national discussion.
People started looking at police work and forensics with a more critical eye. The movie made viewers ask questions about justice and safety in the country.
Case Coverage in South Korean News
South Korean news influences how mysteries and crimes are seen by the public. Major networks like KBS and MBC reach millions of viewers with their crime coverage.
Stories are often detailed, helping citizens learn about the crime, police actions, and possible suspects. Sometimes, coverage is criticized for being too sensational or not fully accurate.
Still, the media’s attention helps keep old cases alive in people’s minds. News outlets played a key role in spreading information about famous unsolved crimes, including cases listed on sites such as The Smart Local.
The coverage can also shape public trust in the police, especially when mistakes or unsolved cases make headlines. By reporting on these issues, the news helps South Koreans better understand crime rates and ongoing investigations.
Patterns in Crime Rate and Unsolved Cases
South Korea is known for its low crime rate, but a few unsolved cases have left a lasting mark on the nation. Looking into crime trends and the effects of these mysteries shows how rare events can shape public feeling and trust.
Trends in South Korea’s Crime Statistics
South Korea often reports a lower crime rate compared to many other countries. Police data shows that violent crimes make up a smaller part of the total crime cases, and homicide rates remain low.
Some high-profile unsolved cases have gained national attention. The famous Hwaseong serial murders, for instance, remained unsolved for decades, becoming one of Korea’s most infamous cold cases.
