On December 22, 2022, the news of Zhu Ling's death attracted a lot of attention.
At the age of 50, she ended her life early because of the thallium poisoning in 1994.
She is a talented girl from Tsinghua University, but because of thallium poisoning, she is disabled for life, and her intelligence has deteriorated to the stage of childhood, which makes her family feel distressed.
However, to this day, there is still no law for the poisoned **, making the case of Zhu Ling's poisoning an unsolved case.
However, everyone still locked their eyes on one person, that is, Zhu Ling's roommate back then, Sun Wei.
From 1994 to the just arrived 2024, who was the original poisoner?
What kind of contradiction is there between her and Zhu Ling?
And why can they stay at large?
Zhu Ling has a warm and happy family.
Born in 1973, her father is an employee of the ** Bureau, her mother works in an ocean shipping company, and her grandfather also has an enviable status.
She has an older sister with her father's surname, called Wu Jin, and her surname follows her mother's.
Both children are very good under the cultivation of their parents, not only excellent academic performance, but also proficient in piano, chess, calligraphy and painting.
However, one day in 1989, their family suffered a huge change.
Wu Jin was a second-year student at Peking University at the time, and during an outing, she and her classmates got separated, accidentally fell off a cliff, and died.
After learning the bad news, Zhu Ling's family fell into great grief.
Fortunately, Zhu Ling was well-behaved and sensible, and was successfully admitted to Tsinghua University in 1992, which made his parents' faces smile again.
On the university campus, Zhu Ling is as good as ever.
She excels in learning, plays the guzheng well, and meets love, which is the object of envy in everyone's eyes.
Zhu Ling lived in a four-person room at school, but since her sophomore year, her relationship with the other three has become delicate.
Perhaps because of love, Zhu Ling rarely stayed in the dormitory during the day, and went back late at night, so he often woke up his roommates.
The roommate who used to be able to chat and listen to songs together is now resentful of her more and more.
And not long after, Zhu Ling's body underwent obvious changes.
Among her three roommates, Wang and Jin were admitted to Beijing from other places, while Sun Wei is an authentic Beijinger, who is said to have a prominent family background and a very hard background, which may be one of the reasons why the case was left unresolved later.
In November 1994, not long after the start of his junior year, Zhu Ling's body suddenly felt unwell.
At the end of the month, her stomach hurt so badly that it even affected her eating.
When my father learned about this, he didn't think much about it, but just asked her to go to the clinic as soon as possible.
But then, Zhu Ling not only had a stomachache, but also pain everywhere on his body, and his hair fell out a lot, looking very haggard.
But because she was going to perform at the ** meeting in the near future, she was busy training every day and didn't have time to see a doctor.
On December 11, the ** meeting was held as scheduled.
Zhu Ling's performance was excellent, and she surprised everyone with her song "Guangling San", but this became the last performance in her life.
She was absent from the celebration that night, and she returned home after the performance after not eating for three days.
Accompanied by her parents, she came to the hospital, but after some examination, the doctor could not find **, only gastroenteritis**.
A month later, Zhu Ling, who had already lost his hair, grew his hair again.
She felt much better than she had ever done and went back to school before the holidays were over.
On February 20, 1995, the second semester of my junior year began.
Because Zhu Ling's body has not fully recovered, he can only rely on his roommates to help bring lunch and dinner.
Maybe Sun Wei is a little more talkative, or maybe she has a bad relationship with the other two roommates, in short, the "burden" of helping her bring food falls on Sun Wei.
But at the beginning of March, Zhu Ling, who had already improved his health, suddenly couldn't even stand up.
Her body was in severe pain and was rushed by her parents to *** there, where the doctor mentioned thallium poisoning for the first time.
Because hair loss and abdominal pain are the most obvious symptoms in the early stage of thallium poisoning, it coincides with Zhu Ling's physical performance.
However, both Zhu Ling and the teacher denied the speculation that Zhu Ling might have been exposed to thallium, so the doctor gave up continuing to investigate the matter.
As Zhu Ling's condition continued to deteriorate, it was extremely difficult to breathe.
In desperation, she had to be sent to the ICU and intubated**.
For the next 5 months, Zhu Ling was in a coma.
The family's money was spent like water, but the expenditure of hundreds of thousands could not bring back the slightest improvement in the daughter's condition, which made the family fall into a collapse for a while.
One day, Zhu Ling's junior high school classmate Pei Zhicheng went to the hospital to see her.
When he saw his old classmates who were suffering from illness, he suddenly had an idea, that is, to do his best to find out Zhu Ling's ** and let Zhu Ling get an effective **.
At that time, the Internet was not yet widespread, but the campus of Peking University was one of the few places where the Internet could be accessed.
Pei Zhicheng wrote about Zhu Ling's situation on the post and launched a request for help from foreign forums.
Soon netizens from all over the world began to reply to the letter, and in just ten days, Pei Zhicheng found a general answer from more than 1,600 letters, that is, Zhu Ling is likely to be thallium poisoning.
His discovery immediately attracted the attention of the hospital, and after introducing the latest equipment, the hospital conducted a comprehensive examination of Zhu Ling, and finally confirmed that she was indeed thallium poisoning.
The thallium content in Zhu Ling's body seriously exceeded the standard, hundreds or even thousands of times higher than that of ordinary people.
The doctor judged that the toxins in Zhu Ling's body were accumulating slowly, and the amount of poisoning in the second time was much higher than that in the first time.
After clarifying **, Zhu Ling's parents ran around and asked someone to find the antidote to thallium poison - Prussian blue.
However, although Zhu Ling woke up four months later, because there were too many toxins in her body, all the functions of her body were seriously damaged, and she almost completely lost her ability to take care of herself.
And her originally smart brain suffered from brain atrophy due to too deep poisoning, causing her intelligence to stay in the childhood stage.
Zhu Ling's parents chose to call the police, but this seemingly simple case has not been solved until today.
The reason why the difficulty coefficient of the case is not big is because Zhu Ling has been living on campus, so she can basically lock down the person who poisoned her person, so she will have the opportunity to poison her diet.
In addition, the poisoner must have the opportunity to come into contact with thallium, and know the properties of thallium, know the symptoms of thallium poisoning, and how to grasp it so that he can not let people die, but also achieve some of his own goals.
Combined with these inferences, many netizens deduced that the poisoner should be her roommate.
Among the three roommates, the biggest suspect in locking up is Sun Wei.
Because Sun Wei's subject needs to come into contact with thallium, he also helped Zhu Ling bring food for a while.
The important thing is that she, like the other two roommates, has a bad relationship with Zhu Ling.
Because a lot of evidence pointed to Zhu Ling's poisoning on campus, ** decided to block Zhu Ling's dormitory.
However, after receiving advance notice from the school, Zhu Ling's dormitory was burglarized, and only her personal belongings were missing.
Obviously, the poisoner was by her side, so she was able to do it as soon as she learned the news.
Her toothpaste, toothbrush and lunch box were missing, these were her personal belongings, but the thief was able to do it accurately and did not take it wrong, indicating that the suspect knew everything about Zhu Ling, and was obviously a person in the same dormitory.
The reason why he chose to steal these items was that the person who should have poisoned Zhu Ling with these items before.
Because they were worried that the police would find clues on the items, they hurriedly destroyed the evidence.
But the suspect did not steal the thermos.
According to netizens, it should be that roommates sometimes use a hot water bottle with each other, so the poisoner did not poison the hot water bottle through the hot water bottle, and naturally did not take the hot water bottle away.
We mentioned earlier that Zhu Ling's grandparents have a certain social status, but when ** revealed that he had enough evidence and would be able to solve the case soon, the case went to a dead end.
Obviously, it is not that ** is incompetent, but that there is a powerful force oppressing them, resulting in ** having to delay the case again and again, and the real suspect cannot be announced for a long time.
Thinking of Sun Wei's grandfather is a master of industry and mining, and his family is illustrious, I have to say that if their family deliberately obstructs it and deliberately puts pressure on the **, then everyone will know everything.
At the beginning, Zhu Ling's three roommates all chose to change their names later.
Sun Wei is now called Sun Shiyan, and some netizens have interpreted this, saying that Sun Shiyan is homophonic "Sun Shiyan", which means to remain silent and not tell the truth.
At that time, Liu Qing, a classmate of Liu, and Zhou Xin, a classmate of Zhou, even really changed their names and surnames, one changed to Wang Qi and the other to Jin Ya.
Wang Qi is homophonic "forget it", that is, forget the past;
And Jinya is homophonic for "today dumb", as the name suggests, choose to be dumb and keep silent about everything.
After the original case, Sun Wei, with the help of his family, chose to go abroad as soon as possible.
If she hadn't been a thief, why would she leave at that time, and why didn't she defend herself?
After being named the top suspect, Sun Wei and his family remained silent at first.
They didn't shout grievances on social **, which is somewhat puzzling, if they are really wronged, don't they really need to defend themselves?
What's more, she was just a college student at that time, was she willing to bear the charge of poisoning and never wash away her grievances for the rest of her life?
may have heard more and more doubts, and later Sun Wei hoped to use ** to return himself a "justice".
However, the result of the facts was unexpected, and even those who interviewed her began to suspect that she was the real poisoner.
Seeing that the matter was revealed, Sun Wei not only refused to continue to be interviewed, but also asked ** to remain silent and did not allow them to publicly interview their contents, and specially asked them to sign a confidentiality agreement.
This undoubtedly made her more and more suspicious, but no matter how everyone talked about it after that, Sun Wei never said a word.
It's not that she doesn't want to defend herself, but she knows that in the face of the facts, the more she says, the more wrong she is.
Even her family did not think about defending their daughter, but chose to move away from the fingers of those around them.
If he hadn't really done something bad, with the high prestige of the Sun family and Sun Wei's arrogant personality, how could he endure the wrongs of others without making any resistance?
In Sun Wei's few voices, it is not difficult to see that she wants to divert her attention, and has repeatedly mentioned that she is not the only one who can contact thallium from the laboratory.
As a top student at Tsinghua University, as the biggest suspect, she naturally knows the importance of evidence.
Therefore, all kinds of physical evidence that can point to the suspect will disappear just right.
There is also an anomaly, after Zhu Ling's poisoning case, other classmates kept a certain distance from their roommates, and would rather go out to fetch water than drink water in the dormitory.
But Sun Wei and the three are different, and their relationship is better than before.
Out of instinctive self-protection thinking, there is only one possibility for the three of them to do it, that is, to cover each other and become grasshoppers on the same line.
Thinking of Wang Qi and Jin Ya's current work, no one dares to guarantee that this is due to their own ability, or someone will help them.
Some time ago, a lawyer proposed that he wanted to retry Zhu Ling's case, but because the evidence was stolen and the suspect's background was too strong, he has not yet received approval for retrial.
No matter what, Zhu Ling's departure is regrettable.
After her death, everyone shouted one after another, hoping that the relevant departments could thoroughly investigate the case, let the real culprit be punished by the law, and give Zhu Ling justice.
After all, Zhu Ling should have had a good life, if she hadn't been poisoned, she would have a successful career and a happy family now!
