Author丨Yan Comob Lou continued to talk about Zhu Ling's case today. This case is asked every year, but every year there is no result. On November 24, Zhu Ling died on the winter solstice, the darkest day of the year. In the end, she did not wait for the verdict of the law. Although her lawyer said that Zhu Ling's departure would not take away the truth, let alone justice. But 30 years have passed, what truth can there be?She used 30 years of unyielding struggle to tell us that there is never a shortage of unjust souls on the Huangquan Road. Justice will not only be late, but will also be absent. When you are alive, you can't get justice, and you can only count on heaven after you die. No matter how uneasy it is to be unsettled, including many righteous-minded people, Zhu Ling's case is the last time it has been on the hot search, and the last time it has been paid attention to. The poisoning case was closed in 1998, and there is no way that the truth will come out again. and Zhu Ling's case is also listed as one of the three major unsolved cases on campus, as well as her sister Wu Jin. This bright and ballet-loving Peking University school flower fell off a cliff during a spring outing, and his death was also unknown. Regarding these two cases, especially the Zhu Ling case, the span is long, the details involved are many, and the characters involved are so wide that an article can be written from any angle or point. You may know some details from different channels, but today I will briefly talk about the complex issues and sort out the ten suspicious points in Zhu Ling's case with you. Some say it's the most perfect crime ever. But I don't think that because the answer lies in these nine doubts. First, thalliumThallium is a highly toxic chemical, classified as cyanide in class A, and few people have direct exposure to this substance. But it was this highly toxic substance that entered Zhu Ling's body twice before and after, the first time it was poisoned for 4 months, and the dose exceeded 40% of the lethal dose, and the second time the dose was increased, reaching 220% of the lethal dose. It was the second poisoning that made Zhu Ling completely collapse, not only blinded in both eyes, but also caused serious damage to the nervous system, his intelligence dropped to the level of a few years, and he was completely unable to take care of himself. If the first poisoning is a warning, then the second time is Zhu Ling's life. So, thallium comes from **?And who poisoned it?Second, thallium with herWhether it is the experts of the hospital or the investigation of **, they all believe that the first scene of the crime is Tsinghua University. Tsinghua University, on the other hand, denied that the analysis center had thallium, and insisted that undergraduate students could not access thallium. However, in a thallium store in Shijiazhuang, the purchase record of a research group in the Department of Chemistry of Tsinghua University was found. The group consists of 3 graduate students and 2 undergraduates, and the supervisor is Xue Fangyu, deputy director of the Department of Chemistry. That is, Tsinghua University lied, and it is not that no undergraduates have access to thallium. 
The two undergraduates who had access to thallium were a male student in the class of '90 and a female student in the class of '92. And this girl is Sun Wei, a good best friend in the same dormitory as Zhu Ling. As a result, Sun Wei became the biggest suspect in this poisoning case. Third, Sun WeiBut the strange thing is that it was not until two years after the case was filed that the 14th Division of the Beijing Municipal Public Security Bureau summoned Sun Wei. After eight hours of interrogation, Sun Wei signed the transcript, which was later cleared of suspicion and taken away by his family. This was the first and only time that the police had summoned Sun Wei. After that, Zhu's father repeatedly asked the Public Security Bureau about the progress, but was told that "an investigation is underway", and later learned that the case was closed in 1998. In other words, the public security department stopped the investigation on the grounds of insufficient evidence. However, it is rumored on the Internet that Sun Wei's family background is prominent, his grandfather and uncle are both high and powerful, and they have tried their best to protect Sun Wei. So the matter was suppressed, which was called a sensitive topic at the time, and no one dared to discuss it. Sun Wei denied this, saying that her grandfather died in 1995, and the public security organs only summoned her in 1997. Probably due to pressure, Sun Wei married an American in 2006 and later immigrated to the United States. Previously, she changed her name to Sun Shiyan, and even changed her date of birth. But in 2013, a local Chinese co-branded ** to demand the investigation and expulsion of Sun Shiyan, a suspect in the "Zhu Ling case", on the grounds of "marriage fraud". Later, she moved to Australia and disappeared from the world. But the label of the suspect in the "Zhu Ling case" has always followed her. We cannot know for sure whether she is the poisoner or the victim of Zhu Ling's case. She said she wasn't the only one at Tsinghua University who had access to thallium salts. In order to prove that what he said was true, he also let his brother enter the laboratory of Tsinghua University, and filmed ** to prove that the laboratory management is not strict. She once said that she was the one who most hoped to find the real culprit. Fourth, two theftsWhen Zhu Ling was diagnosed with thallium poisoning, the doctor advised to call the police immediately. But Zhu's father, Wu Chengzhi, made a decision that people regretted for the rest of his life, he did not report the case to the public security, but called Xue Fangyu, deputy director of the Department of Chemistry of Tsinghua University. It may be that Zhu Ling's parents were busy taking care of Zhu Ling at that time, so they entrusted Xue Fangyu to immediately move out of the same dormitory classmates to protect the scene. Xue Fangyu reported the case to the security office of Tsinghua University and did not seal the scene. Subsequently, the security department not only did not call the police, but also notified Zhu Ling's classmates in the same dormitory, telling them that Zhu Ling was diagnosed with thallium poisoning, and asked you to keep Zhu Ling's things. Then, a strange scene appeared. The thief entered Zhu Ling's dormitory and identified Zhu Ling's glasses case, toothbrush cup, makeup mouth, etc. Although the case was later filed, without key physical evidence, the investigation reached an impasse. In fact, this is not the first time that Zhu Ling's related items have been stolen. In 1998, Zhu Ling's camera, honey and coffee were stolen again from the Tsinghua University laboratory, and Tsinghua University offered to compensate for it. Zhu Ling's items were stolen twice, what did someone want to cover up?Fifth, there are 14 public security departmentsAfter the Zhu family called the police, the public security organs attached great importance to it at that time. Wang Bu, a veteran criminal policeman with decades of criminal investigation experience, believes that "the scope of suspects is very small, and they are next to Zhu Ling." Who can come into contact with thallium and be familiar with Zhu Ling's living habits and wait for the opportunity to poison him?Before Zhu Ling was poisoned for the first time, she was temporarily blind twice, and someone may have poisoned her ** glasses. And the second time, because Zhu Ling brought food from home, Sun Wei brought coffee to Zhu Ling every day, and this cup was later found under Sun Wei's bed. 
Li Mucheng, director of the Tsinghua University Police Station, once said to Zhu Ling's parents: "There is a target, and after the approval from above, they will start to fight each other in close combat." The case-handling staff of the 14th Division of the Municipal Company Bureau also told Zhu's father, "Just a layer of window paper, it will be broken if you poke it." "But 30 years have passed, but no one dares to poke this layer of window paper. In 2006, Li Mucheng, who had retired, said that this incident was hosted by Li Shusen, the 14th Criminal Police Team of the Municipal Company Bureau, and I was just doing assistance work. Li Shusen, on the other hand, faced the reporter's questioning: "This matter has reached a certain conclusion in the investigation work, but from the perspective of discipline, I can only say that I am sorry, I can't answer your question." In May 2013, Zhu Ling's case once again attracted attention. Ping An Beijing has responded that due to objective factors such as the loss of evidence, it cannot be detected in the end, and the public is requested to look at it rationally. Thirty years have passed, and the insiders who participated in the handling of the case have almost gone. Sixth, Pei ZhichengFor this poisoning case, Pei Zhicheng was an accident. On April 10, 1995, Bei Zhicheng, a 92-level student of the Department of Mechanics of Peking University, went to the hospital with his classmates to visit his high school classmate Zhu Ling, but he was shocked by the scene in front of him. Zhu Ling, who was lively and cute and versatile in the past, was unrecognizable, covered with tubes, and lay unconscious on the hospital bed. The key is that the hospital can't detect **, and can only diagnose and treat acute neuritis. Pei Zhicheng decided to do something. Then he and another classmate, Cai Quanqing, translated Zhu Ling's illness into English and sent a distress email to the world through the Internet. Don't forget, that was China in 1995. It is said that Bei is also a red three, and his family background may be more powerful than Sun. At that time, people who could go to Peking University and have access to the Internet were indeed either rich or expensive. It was precisely because of his appearance that Zhu Ling was saved. Soon, he received more than 2,000 responses from 18 countries around the world. 30% replied that this was a typical phenomenon of thallium poisoning and recommended an immediate Prussian blue detoxification. Strangely, two years later, in 1997, Pei Zhicheng, who was about to graduate, suddenly dropped out of Peking University. I don't know if he was persuaded to quit because he made a mistake, or because he started a business early. But on the issue of Zhu Ling, he has always firmly believed that Sun Wei was the one who killed Zhu Ling. Seventh,**Zhu Ling was poisoned for the second time, because the symptoms were relatively serious, so he was directly sent to the *** Director of the Department of Neurology Li Shunwei's first reaction was thallium poisoning, because there had been a Tsinghua thallium poisoning incident before. However, Zhu Ling denied that he had been exposed to thallium, and the possibility of thallium poisoning was ruled out after consultation with the hospital. Then poor Zhu Ling was pushed into the neurology ward, his trachea was cut, his chest was also cut, and he changed his blood 8 times before and after, and he was also infected with hepatitis C in the process, and finally he could only be maintained by a ventilator. If it weren't for Pei Zhicheng's timely appearance, there would never be Zhu Ling in the next 30 years. However, when Pei Zhicheng obtained the thallium poisoning information given by medical experts around the world, the director of the ICU of the association hospital refused to admit the misdiagnosis. According to Pei Zhicheng's recollections, the director not only did not feel guilty at all, but also said in public in a very absurd manner that "this incident is an attempt by Western anti-China forces to use this incident to stink China's medical circles." On the one hand, the Union Hospital claimed that it had no ability to detect thallium poisoning, and on the other hand, it refused to provide Zhu Ling's test samples. Later, with the help of a young doctor, he got Zhu Ling's blood hair. Subsequently, Chen Zhenyang, an expert from the Beijing Municipal Institute of Occupational Disease Health Prevention and Control, withstood the pressure and conducted a laboratory test for Zhu Ling. The result shocked Chen Zhenyang, and the thallium in Zhu Ling's body exceeded 40% of the lethal amount!It was this diagnosis that brought Zhu Ling's life to a turnaround. But at this time, 50 days have passed since Zhu Ling's arrival in ***, and he has suffered serious sequelae. Five years later, ** was sentenced to compensate Zhu Ling for medical losses of 100,000 yuan due to misdiagnosis. Eighth, hackersOn March 25, 2002, Pei Zhicheng published "Some Circumstances of the Zhu Ling Case" under his real name. In this long article, Pei Zhicheng said that he could almost believe that Sun Wei killed Zhu Ling**, and broke the news that Sun Wei had a conflict with Zhu Ling in the Chinese orchestra for the opportunity to perform on the guzheng. There is also a detail in the article that when Pei Zhicheng visited Zhu Ling, he heard Zhu Ling mutter, "I still regard Sun Wei as a good friend, no wonder she always brings me coffee to drink when I am resting." On December 30, 2005, Sun Wei issued a statement in the Tianya community refuting the rumors in the Zhu Ling case, refuting the allegation that the Sun family had intervened in the case through high-level backgrounds, and claiming that he was innocent and a victim of the Zhu Ling case. Sun Wei's statement was quickly supported by a reply from his classmates, which strongly proved that the management of the laboratory was indeed chaotic at that time, and said that Sun Wei and Zhu Ling had no contradictions, and Sun Wei had a cheerful personality and did not have the frame of a ** child. At the end of 2005, a "hacker" cracked the email address of Sun Wei and related personnel, and obtained information such as the "posting guide" for Sun Wei to guide several classmates to support her in clarifying the suspicious statement. On May 6, 2013, Xinhuanet published a comment asking "The case is stuck in **?."Was there any undue interference from power in this case?It was subsequently deleted. Even after all this time, Zhu Ling's case is still a sensitive topic. Ninth, the Sun Wu familyOne is a scholarly family, and the other is a powerful nobleman. The Sun family and the Wu family are closely related. Sun Wei and Zhu Ling are classmates, Sun Wei's brother and Zhu Ling's sister are also classmates, and Sun Wei's father and Zhu Ling's father are colleagues in the same unit, everything is so coincidental. Zhu Ling's sister Wu Jin died strangely during the spring outing, ** The characterization given was an accidental fall from the cliff, but there were no obvious scars on her face, and the time of the electronic watch in her hand was also stuck at 10 o'clock. And Sun Wei's elder brother and Wu Jin happened to be classmates. Although this does not explain anything, some people say that the later theft of Zhu Ling's dormitory was committed by Sun Wei's brother. But the law talks about evidence, and without complete evidence, there is no doubt about the guilt. So even if we know that ** is right in front of us, we can only helplessly watch her perform. On Zhu Ling's 50th birthday, Zhu Ling's father, Wu Chengzhi, said calmly, in fact, we already know the truth, and we have let go of the matter itself. What kind of festival did the Sun and Wu families have, we have no way of knowing. We only know that Chang Wei Fufa does not rely on the head of a leopard, nor does it rely on Bao Longxing. If it weren't for the yellow coat, let alone the Qi Qin clan who was beaten into a trick, even Bao Longxing would be difficult to protect himself, and it would not be enough to die a hundred times. Now when I look at Stephen Chow's "Jiupin Sesame Official", I realize that the shooting is not nonsensical at all, and I cry with a smile. I always thought I didn't understand his humor, but now I know that I don't understand his sadness.
