I'm a street kid, but my wife, a policewoman, won't divorce her

Chapter 731 Raw Materials Link!

Cao Xiuyuan said that in his previous experience, he had seen serial murderers show evolution in their thinking and even methods.

This was not difficult to understand for Chen Xiao and the others.

But Chen Xiao's later words also indicated that this murder case was not something Cao Xiuyuan had encountered before.

Now, foreign forces are involved behind this murder case.

Although the case currently has a very bad impact, the murderer's rampant behavior has aroused the anger of senior management.

But if the task force can find out the person who actually used the murderer's knife, then their merits will outweigh their faults!
After Cao Xiuyuan understood what he meant, he stood up and said:
"Okay, I'll go back to the provincial capital and find the relevant leaders to explain the current status of the case. As for Xiaozhuangnan Town, I'll trouble you all!"

After saying this, Cao Xiuyuan shook hands tightly with Chen Xiao.

Chen Xiao could feel that Cao Xiuyuan had a strong desire to capture all the murderers involved in the case.

But Chen Xiao said nothing, because everyone in the task force now had the same idea.

After waiting for Cao Xiuyuan to leave, Chen Xiao quietly sat back in his chair.

Now there is a solution. Although this method has some gambling flavor, it is also one of the better methods at present.

Sun Zhou and Qin Fei sat down, closed their eyes and meditated, and did not speak to disturb them.

Soon, Chen Xiao was the only one left in the entire office.

He was still thinking about how to complete the method of obtaining evidence.

Right now, they are adopting a two-pronged approach.

Cao Xiuyuan went to the provincial capital ahead and asked his superiors to allow them to take the risk.

Xiaoji and Black Cat are about to arrive at Xiaozhuang South Town in the rear. They will investigate the online traces of the knife's use.

In Chen Xiao's opinion, the arrival of Xiaoji and Black Cat should bring him good news.

Because this is not Zhushan City, nor is it the provincial capital, it is just a small town in the south of the village.

In the year of 06, Internet cafes and even illegal Internet cafes have sprung up like mushrooms after rain.

If it is in a big city, it is not easy to find traces of illegal Internet cafes, but it is very easy to find in a small town.

I think with Black Cat's methods, it shouldn't be a problem to find out something.

Chen Xiao's mind began to slowly let go of the black cat.

He wondered if there were any other ways to capture evidence besides these two possibilities.

Cao Xiuyuan was looking for a witness.

Xiaoji and Black Cat went to look for traces on the Internet, which were equivalent to physical evidence.

However, if Black Cat and the others found something, there seems to be a high possibility that the evidence can be overturned.

If the physical evidence is not complete, the witnesses alone will not be able to stand firm in the court.

Therefore, if Chen Xiao must find another possible source of evidence, he must start with physical evidence.

Furthermore, Ye Jun has shown a strong interest in Liu Dayou.

This was a trap plan set up by Chen Xiao for the criminal suspect.

The probability of success of this plan is also not very high, but based on the murderer's speculation, this should be something he would be very interested in doing.

Thinking of this, Chen Xiao's mind was once again attracted by the word "entrapment".

"If I were Ye Jun, when someone said those words in front of me, would I be interested in doing the same thing?"

"Yes, he would even subconsciously want to do that! Because he has already shown his curiosity about Dayou." "And now that he is full of ambition, his inner desire for challenge should be stronger, so the possibility of him taking action against Dayou is also higher."

"But, does he really not know the man holding the knife?"

This question suddenly popped into Chen Xiao's mind like a flash of inspiration.

As soon as he flashed in, Chen Xiao seemed to immediately erect several walls, surrounding this problem.

At this moment, he felt that this issue was very important!

Suppose that Ye Jun is the knife that Chen Xiao and others were reasoning about.

Then the most important person in the whole case is the person who holds Ye Jun's knife.

But before this, neither Chen Xiao, Qin Fei, Cao Xiuyuan, nor Sun Zhou had ever discussed whether Ye Jun knew the man holding the knife.

Furthermore, this acquaintance has a degree.

The two must have come into contact.

Whether it is online contact, telephone contact, or real-life contact.

There must have been discussion between the two about killing Yuan Keyu.

At the moment, Chen Xiao was thinking about this question, not because he wanted to know what they were talking about.

Rather, I am thinking about the extent of contact between the two people.

After only meeting once, Ye Jun's knife was already firmly held in someone's hand.

Or, after long-term contact, Ye Jun was willing to become the knife in the hand of the man holding the knife?

There is a huge difference between the two. If it is just a brief contact, then there is nothing to think about this issue.

But what if the entanglement is deep?

For example, the spy planted by foreign forces in Xiaozhuangnan Town has always been by Ye Jun's side?
Also, the owners of the house where Yuan Keyu had the accident, father and son Sang Yupeng and Sang Xiaoming!
Thinking of this, Chen Xiao immediately picked up the marker on the desk and walked to the whiteboard in the office.

He wrote down the names of Ye Jun, the man holding the knife, Sang Yupeng, Sang Xiaoming and others.

But everyone stays in their own circle.

Chen Xiao looked at the circles and immediately took out his cell phone and called Qin Fei.

"Captain Qin, please ask the household registration police in the police station to help you. Ask them to find out who is related to Ye Jun's family. Even if they are distant relatives, they must record their names!"

"In addition, we have investigated Sang Yupeng and Sang Xiaoming before. If we only investigated their immediate family members, then we should also compile the information of their distant relatives. After that, write down their names and send them to me."

Upon hearing this, Qin Fei first said "OK" and then asked:

"What are you looking for?"

"Find the connection! From Professor Yuan's route to Xiaozhuang South Town and the clear destination, we have always believed that Sang Yupeng and his son are important suspects in the case. However, no matter how important they are, we still cannot be sure whether they are involved in the murder."

"In addition, Officer Dou's death makes us more suspicious of Ye Jun. Since Sang Yupeng and his son are important suspects in the case, and Ye Jun is also a suspect, are there any connections between them?"

Qin Fei understood what Chen Xiao meant and said, "You feel that there is no commonality in the relationship between the direct relatives, so you want to find a possible connection between the two from the more distant relatives, right?"

"Yes, there is another reason why Professor Yuan came to Xiaozhuangnan Town. We now have evidence to speculate that he most likely came for the academic research in his field and to protect his successors."

"So Zhushan City is the source of raw materials in their field, which becomes the most important information, or the end point of the link I want to find!"

"I want to establish a relationship between all of them and the raw material production areas through relationship sorting!"
