Judging from the existing clues, this suspect B is indeed the best breakthrough, after all, his characteristics are too obvious, and it is much easier to find in this vast sea of people.

However, Shao Dong shook his head again at the moment and said: "I'm afraid it won't be that simple, judging from the criminal methods and cautious attitude of this group of people, I don't think they will easily let this criminal suspect B appear in the public's field of vision, it is estimated that he will be hidden before and after the crime, and he will be more careful if he leaves such a hidden danger as Shen Yue, I estimate that this criminal suspect B will not even go out in a short period of time, and he will hide somewhere for a long time, and he will not show up until the limelight passes." ”

I have to say that Shao Dong's words are like a basin of cold water, poured on everyone's heads in the cold winter.

But it also has to be said that this statement is absolutely valid, because judging from the past, this group of criminal suspects is obviously not such a simple criminal, from beginning to end, their plans, actions and preparations in the early and late stages are very precise, but if there is a trace of risk that may be exposed, it is estimated that they will not do it.

If you look at it this way, it will not be much easier to find that suspect B in a short period of time than it is to find several other people.

The atmosphere that had eased down became tense again after Shao Dong's words.

Thirty hours have passed since the case happened, and nearly half of the golden seventy-two hours have passed since the case was solved.

"Then what should we do later?" Wang Gang threw the question to Shao Dong.

Although he is the captain of the criminal police team, Shao Dong is the deputy director of the county bureau and the deputy head of the 1124 task force.

However, Shao Dong obviously didn't have any better way, and he frowned and didn't say a word for a long time.

If what is on their shoulders is only the pressure of mountains, then what is on Shao Dong's shoulders is a mountain range and a peak, which is pressed on Shao Dong's shoulders.

You know, he made a military order in the first place!

At a time when Shao Dong and others were at an impasse.

Cheng Feng and his party who were in charge of investigating the security company. The work has also been carried out to the end, so far, they have completely investigated the security company, and all the staff in the last five years can basically rule out their suspicion.

On the other side, Wu Zhong and others, who were responsible for investigating Xie Jun's interpersonal relationships, also fell into a deadlock at the same time, and they started to investigate Xie Jun's interpersonal relationships, but they found nothing, especially the veterans who were confirmed by Xue Peng and others had no clues at all.

As an experienced veteran criminal policeman, Wu Zhong also found a problem.

Xie Jun's seemingly complex interpersonal relationship is actually quite simple.

Except for the colleagues who must be contacted at work, Xie Jun actually does not have much contact with people outside. Even his hair, classmates, and relatives knew about Xie Jun through word of mouth. Although many people know a lot of things about Xie Jun, but. On weekdays, I rarely have contact or communication with him.

This is a problem, how does a person who does not like to contact with the outside world and communicate with those veterans know.

Moreover, Wu Zhong also discovered a problem, through the successive understanding of Xie Jun's interpersonal relationships, Wu Zhong found that there was almost no shining point in Xie Jun's body. How did a person who didn't have a shining point of his own get mixed up with a few veterans?

You know, good veterans are very proud. How could they be willing to communicate with someone like Xie Jun or be in the same boat? Even if they wanted to pull him into such a huge and dangerous plan, wouldn't they be afraid that Xie Jun would expose them, or that Xie Jun would drag them back in the process of his actions?

Most importantly, what exactly does Xie Jun have that they can trust?

As the saying goes, things gather people in groups, and judging from what Wu Zhong has learned so far, Xie Jun and that group of veterans are really not people of the same world.

How did two people with completely different personalities, social relationships, and friend circles come together? In the process of their acquaintance, where do they have in common?

In other words, what is the bond of their acquaintance?

Is it a common desire for money, or an introduction to friends. Is it the same unwillingness to live, or is it a few similar pursuits?

As an experienced veteran criminal policeman, Wu Zhong realized the problem here, of course, it cannot be ruled out that he found another way after he broke the clue!

At the same time, in the office of the technical section of the county public security bureau, Wu Wei jumped up from his chair in surprise after reading a test report in his hand.

This is a major breakthrough!

Immediately, he took out his mobile phone and made a call to Shao Dong, without saying a word too much, just asking him to come back quickly, that's all.

Shao Dong, who was eating in the restaurant, received a call from Wu Wei, and with his understanding of Wu Wei, he immediately said, "Have you finished eating?"

"What's the matter?

Shao Dong didn't hide it, and said directly: "There is a clue from Wuwei's side, let's go back and take a look." ”

Because he said this, everyone no longer hesitated, and immediately put down their chopsticks, put away their things and went out to settle the bill.

There was a little episode at the checkout, because Shao Dong had just arrived, and Wang Gang was ready to rush to pay, but after being rejected by Shao Dong for various reasons, he invited everyone to a simple meal, and said that after this case was solved, everyone would have a good meal.

After about ten minutes, the group returned to the county public security bureau.

After returning to the Public Security Bureau, everyone ran to the technical department non-stop, and at this time, Wu Wei sat on his desk with a relaxed look, holding a teacup in his hand and drinking leisurely.

"You're back the fastest this time. Wu Wei saw Shao Dong and others entering the door, and laughed and teased.

Shao Dongcai didn't bother to care what he said, and asked directly: "Okay, don't sell it, let's talk about it." ”

Hehe...... Wu Wei stood up slowly and said, "Come with me, I'll let you see what it means to be a first-class forensic doctor and a first-class technology." ”

Wu Wei himself is a very confident and showy character, Shao Dong has long been accustomed to his approach, and he doesn't feel anything.

Seeing that the leaders have followed, the others have no opinions, and they are also following at the moment.

In the dissection room of the technical department.

In the dissection room, Xie Jun's body lay quietly on the dissecting table. Wu Wei looked at it, pointed at him and said to everyone, "Just him." What do you guys think? ”

"Him?" Zhang Qiang glanced at Xie Jun lying on the dissecting table and said, "Isn't he dead? ”

Regarding Zhang Qiang's question, Wu Wei said in a firm tone: "Dead people are often more true and reliable than the information told us by living people, because living people will lie, and dead people will not." ”

For any professional forensic examiner, they believe in the corpse more firmly than they believe in the confession. In their cognition, the corpse will never panic, but will only truly show everything they encountered before they died, but the suspect will use all kinds of lies to cover up their crimes, this is forensics, this is Wuwei.

"Okay Wuwei, don't talk about your tricks, hurry up and tell me what the situation is. Shao Dong was very helpless about Wu Wei's slow and leisurely attitude.

Now is the time to race against time, and he wants to get the evidence as soon as possible and have a new breakthrough as soon as possible. It's not like I'm here with Wu Wei to talk about some other messy things that I don't have.

When Wu Wei saw Shao Dong speak, he didn't explain anymore, and said directly: "In our forensics, especially in the forensic field, Roca, the father of forensics, once said that the contact between two items will definitely leave something behind or take something away. That's Rocca's Law, I've been thinking about it before. If Xie Jun is a suspect, then he must have been in contact with other suspects. Moreover, the suspect must have had contact with other victims at the time of the murder. I wondered if their contact would leave something behind each other, or take something away. ”

Rocca's law was proposed by Rocca, the father of forensics, so it was named Roca's law, and Shao Dong also knew about this Rocca law.

But there is a prerequisite for this, which is that you have to rule out whether the suspect or the victim has been in contact with other people.

This kind of law means that the contact between two people, as long as they have been in contact, will inevitably leave some traces, or take away some traces, this is Rocca's law, what Wu Wei said, Shao Dong can understand, but what he can't figure out is. How do you determine from the victim that the person who left the mark must be the suspect's?

Because of this question, Shao Dong asked directly: Wu Wei, if the victim has been in contact with others before. So does we apply this Rocca law to him? Does it derail our case, or does it delay our time to investigate a clue that doesn't end up working? ”

Wu Wei seemed to have known that Shao Dong would ask like this. He looked at Shao Dong very confidently, and then looked at the person next to him, and then said neatly: "If I can't even think of this, my forensic doctor is really in vain, before I call you, I have repeatedly taken all the clues and traces that can be obtained from the four victims, and then repeatedly compared them." The physical evidence that can be extracted from them, or the traces left by others, are obtained one by one, in the process. I ruled out all uncertain clues. Because I don't know if the traces and clues left on their bodies will be from daily contact with people. But in the process, I got two identical traces from both corpses!"
