When Lin Zixiao checked the case file of "chemical poisoning of college girls", Wu Guodong also gave a brief introduction.

He did not know how many times he had seen the case. Naturally, he remembered it very clearly.

"This child, it's a pity..."

"As you can see, her name is Zhou Xiaoran, a native of C City. She has learned piano since childhood, and began to learn Guqin at the age of 15."

"In 1992, Zhou Xiaoran showed her talent. She was admitted to C City University and entered class 2 of physical chemistry and instrumental analysis of chemistry department. She was admired by many peers."

"Not only that, Zhou Xiaoran was versatile, joined the college folk band of C City and became the main player. In 1994, he won the second prize of the national college art performance solo group."

"Even, he is a secondary swimmer in city C

"It's a pity..."

Wu Guodong sighed.

"I went to their house a few years ago."

"Zhou Xiaoran used to be rich in food and clothing, but now he has no family. Several walls have been peeled off. Only the most simple and even shabby furnishings can be seen in the house."

"All the furniture added up is just seats, benches and beds. The only exception is the bookcase, which is full of medicines."

"The room next door is easier to lay. There is only a small bed and a hospital bed. The oxygen bottle standing next to it gives people a sense of hospital. In order to take care of her daughter, Zhou Xiaoran's life has changed completely. It's really miserable. "

In Wu Guodong's explanation, and combined with the files he saw, Qi Zixiao made a general understanding of the whole case.

The so-called chemical poisoning case of female students in Colleges and universities refers to the event that Zhou Xiaoran had a strange symptom of chemical thallium poisoning in school, which caused great harm to his health, and finally had to help the Internet to be diagnosed and treated.

At the same time, this is the first attempt of China to use the Internet for international telemedicine.

Because Zhou Xiaoran had no contact history with thallium, the police thought it was a poisoning incident. However, after investigation, the case went up and down several times, and the murderer is still at large with no definite result.

Moreover, due to the police's abnormal behavior in the process of handling the incident, Zhou Xiaoran's case became a public event, which led to various guesses about the suspect's family background.

In April 2013, with the discovery of the FD poisoning case, calls for a thorough investigation of Zhou Xiaoran's case emerged again, and Chen Wei, the former suspect, was also widely disputed by public opinion.

Half a month later, a celebrity donated 100000 yuan to Zhou Xiaoran foundation.

In addition, several public figures, including several stars and groups, also expressed their support.

In May of the same year, Weibo officials blocked the keywords of "Zhou Xiaoran", "thallium" and "Chen Wei", and the relevant contents were also deleted.

When searching for Zhou Xiaoran's keywords on Weibo, the words "search results are not displayed according to relevant laws, regulations and policies".

Two days later, Weibo officials responded, saying that due to the loss of evidence, it could not be detected, and there was no interference in the process, calling on the public to view the case rationally.

In the official response, City C police said Zhou Xiaoran was ill and hospitalized in December 1994. He was confirmed as thallium poisoning on April 28, 1995, and only reported the case on May 5 of the same year.

because the interval time is nearly half a year, the ad hoc group has investigated seriously, but there are no monitoring, crime traces and material evidence in the relevant places, so the direct evidence of the suspect has not been obtained.

The police said that there were some cases which were limited by the investigation conditions and could not be solved due to objective factors such as the loss of evidence. We hope that the public will treat it rationally and respect the law of investigation.

In this way, the case has been shelved for more than 20 years.

"Is man still alive?"

Lin Zixiao opened his mouth and sighed.

"Alive."

Wu Guodong bit his teeth: "I saw it before when I went there. Unfortunately, 23 years ago, the gifted and beautiful female college students in Tsinghua University have been severely paralyzed and completely demented, and they can't even take care of themselves."

"Originally happy, well-off family, now has already been dragged down to a bad shape."

"You say, this man How could it be so bad? "

He sighed: "it's a pity that we really can't do it. The time span is too long, and it takes half a year for poisoning to report a case. Half a year is enough to erase too much evidence and clues, and we can't really find it."

"At the beginning, the means have been exhausted."

"Now More than 20 years later, if you want to break through, you have to rely on your "science."

"Ooh!"

Lin Zixiao was happy: "feelings, now you admit that I am a science? Thought you thought I was superstitious? "

"What superstition is not superstition?"

Wu Guodong spread his hand: "for me now, no matter what superstition, as long as it is useful, that is science!"

"At the most, it is" science "which can not be explained by the present science. Let's call it higher science?"He was a little bit proud: "you said, I used higher-level science to solve cases, and hired you, who can be" more advanced scientific means ", to be a scientific consultant. Is it not scientific to come here

Lin Zixiao: Science, very scientific! It's so scientific. "

"Yes?"

Wu Guodong grinned: "I think so. It's really scientific."

“……”

Lin Zixiao was happy for a while, and then, he sighed: "this case is indeed a pity."

In the past, talented women had both talent and color. They should have a bright future, but now

"Can it be broken?"

When it comes to the case, Wu Guodong is not in the right mood.

"What do you say?"

Lin Zixiao looked up: "yes

"And this one!"

At the same time, she points her finger at "two people and a car missing.".

"This case..."

Wu Guodong hesitated: "this case is not easy to solve."

"It's really strange. Two people, one car, so big, you say, it's not a motorcycle. How can you say it's gone?"

"At that time, almost all the local police officers were employed and a reward was offered. The price was absolutely high in those years, but no one could provide any clues..."

"It's really strange. It's very difficult."

"I want to see how strange it is."

Lin Zixiao said he didn't believe in evil.

Is it difficult? It depends on who is facing, isn't it?

Immediately, Lin Zixiao studied the file carefully and knew the case clearly.

"Two people and a car missing" happened one day in 1996.

Guo Baokun and Wang Guoqing, employees of the struggling plastic factory, drove a Santana car to a second-hand car market in the city to sell cars.

This was originally a normal thing, and in those days, Santana had a lot of face.

But as a result, on the same day, the two people, together with their car, were mysteriously missing, and so far there is no whereabouts.

According to the records of the file, the police in charge of the matter at that time, in order to find Guo Baokun and Wang Guoqing, invested a lot of manpower and material resources and visited a large number of people in the past 20 years, but there was no result.

Guo and Wang were both in their 20s when they disappeared. Their parents were exhausted for more than 20 years.

They promised to thank the police for providing valuable clues to help them solve the case.

According to the file, Guo Baokun, male, Han nationality, was born in May 71, with a height of 1.82 meters, white skin and yellow teeth. On the day of his disappearance, he was wearing a blue jeans suit, grey shirt, brown vest and brown leather shoes.

Carry the salary card of plastic factory, ID card and cash of 1000 yuan.

Wang Guoqing, male, Han nationality, was born on November 24, 1973. He was 1.75 meters tall and fat. On the day of his disappearance, he wore a yellow shirt, a police jacket, blue jeans, blue trousers and brown leather shoes.

Guo and Wang are driving a dark gray metal paint ordinary Santana. The car has a central door lock and automatic glass. It is equipped with full vehicle procedures. The license plate number is ¥ * 25cm.

The engine number and frame number are also clearly recorded.

It is also recorded on the file that the relevant officials of the local Branch Bureau said that Guo and Wang had not been solved after 24 years of disappearance. They felt shameless to face the missing person's parents and family members, and they would never give up looking for the missing person.

This person in charge said: this case is now collecting clues from the society. If you can provide the whereabouts of missing persons and vehicles, or provide clues to solve the case, the Bureau will reward 50000 yuan.

The most bizarre thing about this case is that people and cars are missing together. It's easy to understand that people are missing. It's OK to divide bodies and bury them.

But it's incredible to have no trace of the car. You know, the investigation is very strict. It's too difficult to make the car completely traceless.

How to deal with the car?

It's nothing more than a centralized approach.

For example, driving to other places, burying, burning, cutting, crushing and scrapping, throwing into the lake and so on

But here comes the question.

At that time, although there were not so many cameras, it was almost impossible for a car to drive far away.

Therefore, the possibility of going to other places is not very big, and the police have carefully checked it out and basically can be ruled out.

So, the rest of the treatment, buried must leave traces? At that time, the police carried out a full-scale search on the possible burial site, but still found nothing.

Fire? Can't there be an iron shelf after burning? Can't there be any trace?

Cutting, that thing has to have tools, it has to have sound, right?

Moreover, it was found that no similar trace was found in all the residents near the scene of the crime.In the lake?

Salvaged!

Extrusion scrap?

There are large-scale equipment related to the place, the police also checked, but it is not found out.

"Alas

Wu Guodong suddenly sighed: "at that time, the conditions were really too backward. If it were changed now, I would not believe that I could not find out. There were surveillance everywhere, and the specific location could be determined soon."

"But in those days, we had to figure out the place where the crime was committed and then investigate it one by one. It was just like looking for a needle in a haystack. It was too difficult."
