Chapter 997 Advantages

"This piece of shit, Lao Cui... is a character."

Tao Lu sent Lao Cui and the others out, then looked at Lao Cui's back and said, "That being said, Lao Cui does have some intuition. It's a bit like a sixth sense."

"It's amazing, right?" Liu Jinghui asked.

"I don't know if it's a miracle or not, but we have indeed encountered it several times." Tao Lu mainly explained it to Song Tiancheng, and the leaders of the branch also received a wave of strange knowledge.

"Actually, it's not surprising. There are many coincidences in some cases and people." Song Tiancheng said something useless from a high vantage point.

Liu Jinghui is from outside Beijing. He said with a smile, "Speaking of geniuses, I have seen quite a few. Some of them really have something. Including intuition. Some people are more sensitive than others."

Tao Lu laughed and said, "For policemen like us, saying this would be considered superstition."

Liu Jinghui thought, it seems that the capital does not believe in superstition. Liu Jinghui changed the subject and followed the pattern that the people in the capital liked, saying: "This thing can also be explained by science. Some metaphysical ones are high-dimensional projection, the influence of dark matter, some closer to reality are the influence of magnetic field, like pigeons, and some more basic versions are empirical models, or special physiological structures, such as wild boars looking for truffles."

After he said this, Tao Lu nodded in agreement. In his opinion, Cui Qishan should belong to the last category.

"It would be really interesting if Lao Cui could dig out the body of the kite." Tao Lu said interesting words but his expression did not show that he found it interesting at all.

This case is extremely troublesome! If another insider dies, it will become a real nuisance!

Liu Jinghui comforted him: "Not really. This case happened over 20 years ago. Where can we find a corpse?"

A faint sigh came from behind him: "Don't worry. Even if Captain Cui dug up Yaozi's body, we wouldn't recognize him."

The person who spoke was Xiao Si, who was sitting in the corner, looking through old files and documents. Cui Qishan didn't want to take him out, so he left him to work in Jiang Yuan's group. Anyway, he didn't feel bad about leaving him. If Jiang Yuan dared to second him, Cui Qishan would dare to send him out.

Tao Lu felt as if he had constipation after listening to this.

It's painful because Xiao Si is right.

Yes, until now, the police and the suspects do not know what Yaozi looks like, nor do they have his fingerprints and DNA. Wang Futing has seen Yaozi, but he has not looked at him carefully, nor is he very good at remembering people's appearance. After all these years, Wang Futing has no idea what Yaozi looks like.

In fact, it doesn't matter what you look like. It's only because of Jiang Yuan's skull reconstruction that we can discuss appearance. Otherwise, whether Yaozi is dead or alive has nothing to do with his appearance. This is without considering the increasingly common plastic surgery technology and the makeup technology that can be used.

Thinking of all the possibilities, Jiang Yuan couldn't help but shake his head and went back to look at the files silently.

He didn't object to Tao Lu's strategy. If he was lucky, he could still defeat the master with random punches. In fact, most criminal investigation cases didn't need to be handled carefully. They could be solved with random punches.

The technological revolution in the 21st century is so powerful that people who don’t understand technology can just tinker with it and feel that everything is just that, to the point that everything they see is just a makeshift team.

However, the stage has been set up anyway, so if a few people go up there and sing and dance a bit, maybe everything will be fine.

It's like many cases nowadays, the word "solved" seems barren, they just scanned it with the police communication system and got the result directly. The real test for criminal police has become civilized law enforcement, evidence compliance and other issues.

The case of building a courtyard is just the opposite.

This is an unsolved homicide case. Due to the special identity of the deceased, Zhang Xiaoming, who is the grandson of the Zhang family, the case has basically utilized all its resources on the one hand, but on the other hand, its investigation direction is restricted.

Everything involving politics is very annoying, especially criminal cases. The main focus is on the pursuit of truth, but what truth is there in politics? Politics is only about taking sides.

If Zhang Xiaoming's death was really related to political reasons, even Jiang Yuan would find it difficult to investigate.

To be precise, investigating political cases requires more accurate investigation.

Admittedly, Jiang Yuan can ask Zhang Xiaoming's sister Zhang Xiaoya to provide a lot of relevant information. Given Jiang Yuan's current status, Zhang Xiaoya would most likely be willing to do so. The problem is, without accurate preliminary investigation, what information should Zhang Xiaoya provide?

How does Zhang Xiaoya judge which information is worth telling and which is not?

If it is an ordinary criminal case, the police actually ask you to tell them everything. In the interrogation room or inquiry room, the police will ask very detailed questions, and the level of detail is completely different from ordinary people's chats. This is especially true in terms of breadth. As for what is useful in the case and what is useless in the case,

Moreover, with a situation like the Zhang family and an identity like Zhang Xiaoya, she knows a lot of information, but is it appropriate for her to tell it all?

There are some things that she may be willing to say, but others may not be willing to listen to.

On the other hand, a lot of political information is inherently subjective, and much of it is gathered from hearsay, or to put it more euphemistically, it is the aggregation and re-analysis of information from stakeholders.

Should we tell this subjective news? How true is it?

But what else can we say if we don't talk about these subjective news? For example, was Zhang Xiaoming's death caused by the Zhang family's enemies? Who are the Zhang family's enemies? There is no objective answer to this question.

Therefore, even if Zhang Xiaoya is needed to answer some questions in the end, Jiang Yuan must know what the questions are.

The answers to these questions can only be found in the files.

This look lasted a whole day.

I woke up the next day and continued watching.

Criminal science and technology is essentially a kind of technology. It is a bit frivolous to say that solving a case is like solving a problem, but the basic process is like this.

Jiang Yuan was flipping through the files, hoping to get more known conditions, or to find a way to solve the problem from the existing conditions.

These two things were done together, and from time to time, Jiang Yuan would receive briefings from others, which contained a rough description of the files they had read.

This allowed Jiang Yuan to get a general understanding of the overall picture of the case, and if he was interested, he could read it in depth.

At the same time, more information was sent, especially newly taken photos, which were sent in large quantities, and newly restored films were delivered from time to time.

Jiang Yuan watched like this for two days. At noon that day - without any warning, without anyone reminding him, Jiang Yuan set his eyes on a close-up photo of oil mud.

The oil mud came from the nail crevices of the deceased, which was not too strange. The victim Zhang Xiaoming's workplace before his death had its own mimeograph factory, which was responsible for printing some promotional documents within the factory and was also a place Zhang Xiaoming often visited.

In addition, the printing quality of mimeographed materials at that time was unstable. Even if you did not go to the mimeograph factory and only touched the mimeographed products, you would occasionally get such oil mud stuck in your nails.

However, it is very rare to only insert it between the nails while leaving the rest of the hands clean.

Jiang Yuan took out the photos of the scene and looked at them again. Then, he found Wang Futing's confession and read it carefully.

If the current investigation has any advantages over 20 years ago, Wang Futing is the most important part. After all, he is an eyewitness in this case, although his effect and ability are limited...

As for the murder process, although it took an extremely short time, the police officer in charge of the interrogation still conducted very detailed inquiries diligently and responsibly.

Jiang Yuan quickly found the process of physical contact between the murderer and the victim.

At the moment Zhang Xiaoming fell to the ground, he should have had a brief contact with the murderer. At least in Wang Futing's opinion, he touched the murderer.

In this case, if the source of the sludge was indeed transferred from the murderer, then there is a high probability that the murderer is a colleague.

This can also explain many problems, such as why people want to kill each other as soon as they meet, and why the murderer cannot be screened out in Jianmenyuan where there are so many people coming and going.

However, just this little bit of mud is not enough.

Jiang Yuan thought about it, called Wang Chuanxing again, and said, "Do a statistics to see which people who worked with Zhang Xiaoming later became successful... Well, do this statistics later and see how many people who used to live in the construction courtyard became successful!"

To be honest, this method of directly finding the beneficiaries is an advantage that was not available back then.
