In 2006, Lee Yun-hee, a 29-year-old female college student in South Korea, went missing after having dinner with her classmates and teachers. This incident aroused the attention of the whole Korean people. When the police investigated the scene and sought the truth of the matter, two of Lee Yun-hee’s classmates committed crimes. A fatal mistake was made, so much doubt that it caused extensive discussion at the time. What was it all about?
Lee Yunhee's family lives in South Yangju City, Gyeonggi-do. She has excellent academic performance since she was a child, and she is very beautiful. She is called "the child of other people's family". When she was undergraduate, Lee Yunhee studied at the famous Ewha Womans University in Seoul. , my major is a double degree in fine arts and statistics, but after finishing 6 years of study, Li Yunxi suddenly found that he didn't like this major and didn't want to find a related job.
Li Yunxi and his parents
Although he is not young, Li Yunxi was very courageous and made a decision when he was 25 years old: change to medicine. Because Li Yunxi liked small animals since she was a child, she decided to study veterinary medicine and become a veterinarian in the future. At that time, Li Yunxi’s parents did not agree with their daughter’s choice. They felt that the girl’s job was not important, and Li Yunxi should be married at age. It was the right way to find someone to work early, . However, under Li Yunxi’s strong request, the parents finally agreed to her daughter’s education. Request.
In 2003, Lee Yun-hee, who is excellent in character and learning, was successfully admitted to the Department of Veterinary Medicine of Chonbuk University. Chonbuk University is located in Jeonju. It is a comprehensive school in South Korea and the top ranking among Korean national universities. 5 schools. But what Li Yunxi didn't expect was that entering school would be the last stop in her life.
After entering the school, in order to reduce the financial burden of the family, Li Yunxi earns tuition and living expenses by teaching students part-time outside, so that his parents feel at ease.
In 2006, 28-year-old Li Yunxi started his senior year study in the last semester. As he will officially graduate in one semester, many students are already submitting resumes to prepare for internships. On June 5,After school, Li Yunxi, more than 40 students in his class and a professor from the Department of Veterinary Medicine celebrated with a drink in a restaurant outside of Chonbuk University.
In South Korea, it is common for professors to bring students to drink and celebrate. This kind of event is often held before. As they are about to graduate, the classmates at the dinner are very happy. They drank a lot of alcohol, until 6 At 2 o'clock in the morning on the 6th, the students left one after another and returned.
Li Yunxi and Kim
Li Yunxi rented a house outside the school to live alone for the convenience of teaching, the location is about 1.5 kilometers away from the gathering place. When Li Yunxi left, one of her boyfriends, Kim, stopped I got up and proposed to send Li Yunxi home. Kim has always been in love with Li Yunxi, and Li Yunxi has a good impression of him. It’s no secret among classmates. Li Yunxi also swaggered through the school wearing clothes given by Kim, so Li Yunxi did not refuse Kim's proposal.
The two walked all the way, and when Li Yunxi was about to reach the apartment building, she said to Kim, "It's here, you don't have to send it, let's go back."
Hearing Li Yunxi say this, Kim did not force him to stand still and watched Li Yunxi enter the apartment from a distance. Kim’s location was about 100 meters away from Li Yunxi’s apartment. As the light in the room turned on, Kim felt that Li Yunxi had arrived home, so he turned and left and returned to his residence.
On the second day, the students all went to school. Some people found that Li Yunxi did not come to attend the class. This made the students feel a little strange, because Li Yunxi’s work and rest system is very regular. He has never been late and has never missed class. We did not receive any news that Li Yunxi asked for leave.
After learning about this, Jin also went to Li Yunxi’s residence to check, but the door was locked, Jin knocked on the door, and there was no response inside. Only the sound of a dog barking was heard inside the house. Jin felt that Li Yunxi It is very likely that something urgent has left, so I didn't look for it anymore.
On June 8th, the classmates discovered that Li Yunxi still did not come to class. This kind of thing had never happened to Li Yunxi, so it aroused more suspicions from his classmates. After class, Jin called three classmates to join him. He came to Li Yunxi's residence again.
After knocking on the door for a long time without answering, one of the classmates suggested to go to the upper floor opposite. From there, you can see the situation in Li Yunxi’s apartment. So the four of them came to the opposite apartment building, but they were surprised to find Li Yunxi The windows of the house are open, and the items in the house are scattered all over the floor.
At this time, the four classmates were a little panicked. They called Li Yunxi’s parents and asked if Li Yunxi had gone home. As you can imagine, Li Yunxi’s parents hadn’t met Li Yunxi and didn’t know where she went. The four of immediately realized that Li Yunxi had an accident, so they decisively called the police.
When the police received the alarm call, they immediately sent someone to Li Yunxi’s residence and forcibly opened her door lock. Li Yunxi raised three puppies, because they were hungry for several days and the puppies barked very loudly. It's miserable that they made the room so messy in order to find something to eat.
In the room, no one found Li Yunxi, so the police contacted Li Yunxi’s parents and sister and asked them to come to the scene for questioning. There are frequent cases of disappearance in the local area, and many people will come back after a few days of disappearance. Therefore, the police are more optimistic about Li Yunxi’s disappearance. It may be the case because there is no fighting in Li Yunxi’s room. , And no blood stains, So the police wanted to inquire about Lee Yun-hee’s family.
But four of Li Yunxi’s classmates don’t think so. On June 2nd, Li Yunxi was robbed once. That night, Li Yunxi bought some fruits from the fruit stall near his residence and wanted to take them back to eat, but left. A motorcycle drove up from the back as they walked. The people in the car snatched Li Yunxi's bag from behind and ran away.
At that time, there was a car behind Li Yunxi who saw the robbery.So the owner hurriedly greeted Li Yunxi to get into the car and wanted to chase the robbers, but after some chasing, the motorcycle went into an alley and disappeared without a trace, and Li Yunxi’s package not only had a phone card, but also a mobile phone and identity. certificate.
After these identification cards were lost, Li Yunxi was applying for a replacement at this time, so she could not be contacted by mobile phone at all, let alone location tracking.
At first, the police still felt very confident, but then two of Li Yunxi's classmates made a fatal mistake, which brought the case to a deadlock. Two of the four classmates followed the police to make a transcript, while the other two students stayed . One of them was Jin who took her home after dinner. The two began cleaning the house because of Jin. A certain and another female classmate felt that the room was too messy, and Li Yunxi’s parents would feel bad after seeing them.
Kim mopped the floor, swept the floor, and wiped the table. The female classmate also prepared Li Yunxi’s sheets to be washed in the washing machine. When she turned on the washing machine, she found a pair of underwear and 4 towels in the washing machine. These items have been washed. But it didn't air out, and was covered up. Li Yunxi either forgot or didn't have time to air it.
In addition, there is 400,000 won on the table, which is the part-time salary earned by Lee Yun-hee in teaching, and there is a bunch of flowers on the ground. These flowers should have been hung on the wall, but they fell. On the ground, it is obvious that the puppy can't touch it at all. These flowers are likely to be touched by someone. No one thought that the evidence in the Li Yunxi's residence would be completely destroyed in this way.
At 6 o’clock that evening, Lee Yun-hee’s parents hurried to the school. Lee Yun-hee’s sister advanced into the room. She found a half-length cigarette butt on the window sill. When Lee Yun-hee was in Ewha Women’s University, Lee Yoon-hee was under pressure. She had smoked, but she quit later. My sister thought that Li Yunxi was re-smokers due to school pressure, fearing that Li Yunxi would be scolded by his parents, So my sister took advantage of no one.Throw away half of the cigarette butts.
Li Yunxi’s sister didn’t even realize that the half of the cigarette butt was probably not Li Yunxi smoked, it may be left by other people, or even criminals, but this evidence was also “magical” by her sister. Land" is dealt with.
The night when Li Yunxi disappeared was very hot. Li Yunxi loves cleaning and changes clothes every day. His family searched every corner of the house, but they never found the shoes and clothes she wore that day. Memories with the classmates who had dinner with Li Yunxi The situation of Li Yunxi that day did not reveal anything unusual about Li Yunxi. She talked and laughed with her classmates, and looked very relaxed.
When Li Yunxi came back, it was almost 3 in the morning, so when the police asked Li Yunxi’s neighbors, many neighbors said that they were sleeping deep at the time and did not hear any unusual noises. Even if they did, they heard them at all in that situation. not see.
In addition, Li Yunxi's family also found Li Yunxi's backpack in the house. The students said that this backpack was carried by Li Yunxi at the party that day. This proves that Li Yunxi has returned to the room after the party, but Li Yunxi’s backpack is missing a notebook that he carries with him. No one knows where the notebook has gone.
Li Yunxi has the habit of taking notes, and everything that happens every day will be recorded in the notebook, so as long as you find this notebook, you can find clues.
At the same time, the police also found a lot of doubts. Li Yunxi’s home lacked a low table and a hammer. A good friend of Li Yunxi once accompanied Li Yunxi back to her residence to collect information on June 5. On the stool in front of the table, there is a cup on the low table. She still played with it for a while. Since the low table is very short, it can be used as a desk or a coffee table, so this classmate was impressed by the low table.
Li Yunxi has a toolbox, but lacks a hammer in the toolbox. The police immediately thought that someone might attack Li Yunxi with a hammer and hit the flower on the wall.Li Yunxi hit the low table, so in order to eliminate the evidence, the murderer took away both the hammer and the low table.
The police also discovered that Lee Yoon-hee had used a computer to browse the web from 2:59 to 3:02 on June 6th. This process was only three minutes, after which the computer was never used again until more than one. At 4:21 of the hour, the computer was forcibly shut down.
Li Yunxi has never had the habit of forced shutdown, because forced shutdown may damage the files in the computer, so unless the computer crashes, most people will not use forced shutdown to shut down the computer, and Li Yunxi does not like to turn off the computer, even when going to school sometimes If you don’t turn off the computer, it’s a day when you turn it on.
During these three minutes, the key word Li Yunxi searched on the computer turned out to be "112" and "sexual harassment". 112 was a South Korean police call. The police speculated that Li Yunxi was harassed and caused her I want to check the call to the police.
There were a lot of boys at the dinner party. Will Lee Yun-hee be harassed during the dinner party? However, when the police asked Li Yunxi's classmates, they said that there was nothing unusual about Li Yunxi, but they couldn't rule out such a phenomenon and they didn't know it.
What is even more weird is that the police found through technical means that someone had used a computer to browse the web during the period from 3:02 to 4:21, but these contents were not displayed on the computer because someone was here. A deletion operation was performed on the computer, and related information was deleted. The police could not verify what information was deleted.
So why didn't the deleter delete the three minutes of records? Could it be that these records were deliberately left to lead the police in a misleading direction? The way the computer was forced to shut down also judged that the person involved was probably not Li Yunxi himself, but someone who had appeared in the room.
The evening of June 10. The police also discovered that someone had used Lee Yun-hee’s account to visit a music website.I also checked the email. If I don’t know the login password, Lee Yun-hee’s account cannot be accessed at all. The police suspected that this person was suspected of committing a major crime. Based on the IP address, they discovered that this person was located in a hotel on Yeo Island, Seoul, and the police went immediately. This hotel had acquired the hotel’s surveillance video, but through the surveillance, Li Yunxi was not seen. This situation proved that it is very likely that the suspect knew Li Yunxi.
On June 13, Li Yunxi’s father suspected that someone had thrown away Li Yunxi’s low chair, so he rummaged around in a garbage dump on a slope 20 meters away from Li Yunxi’s residence and finally found this low table and chair, The four metal legs of the table and chair were removed and disappeared. Only one table board is left. Judging from the traces behind the low table, the metal legs were not broken, but were unscrewed with a screwdriver. .
This situation is very abnormal, if in order to dispose of the waste, the recycling staff will directly break the metal feet by hand, because it takes time and effort to disassemble with a screwdriver. Therefore, it is speculated that the suspect was deliberately thrown here. He removed the feet of the low table and chair and took it away. After confirmation by his classmates, the low table belonged to Li Yunxi.
The police again suspected that someone hit Li Yunxi with a hammer that night. Li Yunxi fell on the low table and left marks, so this person must take the low table and the hammer away. Tables and chairs must also be disposed of, but in the middle of the night, low tables and hammers are very inconvenient to carry. In order to avoid attention, the suspect removed the metal feet and took them away.
Through various evidences, the suspect is likely to know Li Yunxi, and of course it is not ruled out that it is a stranger's impulse case.
If an acquaintance commits the crime, the first person to be suspected is Kim who sent Li Yunxi home. Because he has too many doubts, after the dinner, Kim insisted on sending Li Yunxi home. Everything that happened was Kim’s side words. No one knew if he entered the room. After the incident, Kim offered to stay and clean the room.This is the perfect time to dispose of the room evidence.
So the police took Jin back to the police station for investigation and questioning. In addition, at 4:18 pm on June 8th, the computer was turned on. At this time, it was Jin and the female classmate who were cleaning the room. The police asked Jin and Whether the female classmate had turned on the computer, both of them replied "I don't remember very clearly". Of course, it cannot be ruled out that the two of the computer accidentally touched the computer switch when they were cleaning the computer.
Kim has a special feeling for Lee Yoon Hee. He not only records Lee Yun Hee’s daily outfits, but also secretly collects Lee Yoon Hee’s hair and clothing. Although the two have not established a relationship between boy and girl friends, but Have an ambiguous relationship.
Since Kim also lives by himself, he said he went home after sending off Lee Yun-hee, and no witnesses confirmed it.
With the deepening of the investigation, Li Yunxi’s notebook was also found. At that time, the notebook was placed on the desk of the laboratory on the second floor of the school’s veterinary department. The notebook recorded a lot of daily chores, such as every part-time income and a friend’s mobile phone. There are also things that happen every day, but these things are very common. The last message of the incident was "In the afternoon of June 5th, we will have a dinner together after the surgical practice." There is nothing else.
But when did Lee Yoon-hee’s notebook be put on this table? The police guessed that it might be that Lee Yun-hee put it on the table after the operation and forgot to take it, or that someone put it there deliberately.
When asked by the police, Kim firmly denied that he was involved in Lee Yun-hee’s disappearance. The police then inspected Kim’s clothes. There were indeed blood stains on them, but it was not human blood, but Kim was experimenting. Animal blood stained in the process.
As a medical school student, students often do animal dissection experiments, so it is normal to find blood stains on clothes.
But then the police discovered some anomalies, Chonbuk University veterinary department has an incinerator,Every day, professors and students would gather the animal carcasses and burn them, usually weighing 40 kilograms a week, but this week, the weight reached 110 kilograms.
At that time, it was close to the end of the semester. There will be no large animal dissection experiments. Could it be that Li Yunxi was deliberately put in the incinerator? If this is the case, then the perpetrator was from Chonbuk University, so the police asked for money. He agreed to conduct a polygraph test for him, , but the psychologist found that when Jin was answering various questions, his vital signs were completely normal without any fluctuations, which ruled out Jin's suspicion of committing the crime.
At that time, there was also the suspicion of Lee Yun-hee’s professor entering and exiting the school to use the incinerator, but the incinerator did not check what the incinerator was. Since there was no evidence, the police could not determine whether the professor was the perpetrator. Interrupted, the police did not arrest the professor and conduct an interrogation.
In addition, a vacant room was found opposite Li Yunxi’s house. Li Yunxi’s actions can be observed from the room, but this room is not occupied. However, empty cigarette boxes and cigarettes were found on the floor of the room. Toilet paper, it seems that someone has stayed in this room. Maybe Li Yunxi was spotted by someone, and Li Yunxi’s residence is not monitored, so there are few clues left, making the case difficult to detect.
After years of searching, the police still obtained very little, and some new evidence was released one after another. They wanted the whole people to participate in providing clues, but the police did not obtain any useful information.
So how did Li Yunxi disappear? Is the room really the scene of the crime? Twelve years later, a piece of information entered the public eye.
In May 2018, a girl from Xinlin-dong, South Korea, encountered a situation of being followed when she returned home, because there was a video at the girl’s door. From the video, it was discovered that a man was just following her. When she opened the door and closed the door, the man dashed to her door, but only one second later, the door happened to close. The man tried to open the door and failed to enter. He stayed at the door for two or three minutes.As if expecting the woman to go out again, but the result failed, so the man turned and left.
This video was made public, causing a huge psychological panic to Korean women. If a man rushes in, what behavior he will do, many people have answers in their hearts, and the consequences are disastrous. The safety of girls is once again widely discussed.
Inferred a possibility from these phenomena, is that Li Yunxi’s perpetrator may also be an impulse case, or he has observed Li Yunxi from a distance for a long time before he decides to do it. It may be because there is too little evidence to stay in the room opposite Li Yunxi. It was never found.
Coincidentally, in 2019, a girl of the same family next to Li Yunxi’s house also announced a message to the outside world. She said that just a few days before the Li Yunxi case, she had gone home alone when she walked there. When she was on the second floor, she suddenly felt someone following her. She then yelled, waking up the neighbor and scaring away the follower.
On the second night of the case, the girl was hungry and wanted to eat instant noodles, but she couldn't light up the gas. Because she was timid, she did not go out to check the gas valve outside (the Korean gas valves are all in Outdoors), when the girl went out for inspection during the day on the second day, she found that only her gas valve was closed in the whole building. This could not help causing the girl’s fear. If she went out for inspection the night before, would an accident happen? ?
In the months after the incident, the police dispatched 15,000 police officers, printed and distributed 30,000 flyers looking for missing persons, and conducted a carpet inspection of Chonbuk University and the vicinity of Lee Yun-hee’s residence. Nothing was found. The main reason for was that all the evidence in Li Yunxi's room was destroyed, and even Li Yunxi was dead or alive cannot be determined.
If Lee Yoon Hee died, where did her body go? If Li Yunxi hadn't died, why hasn't she been seen so far? This case has attracted the attention of all the people in South Korea, and Lee Yun-hee’s parents have always believed that their daughter is still alive. If she is still alive,This year is 43 years old.
Women's safety has always been the focus of social concern. I just don't know when the Li Yunxi case will be solved. I hope that the old man will get the answer as soon as possible, without leaving any regrets, and the murderer will get the punishment he deserves.
