Looking at Wu Yanhui like that, Mu Yuan was very calm.

After all, so many years have passed, and it's normal for memories to be blurred, let alone to call out names.

People are sometimes like this, remembering that someone exists, but they can't remember what their name is.

Wu Yanhui thought for a long time, and said helplessly: "I really can't remember the name, but I know that he is from the village next door to us, called ...... Tianbao Village. Then...... He drives a tricycle and is responsible for delivering goods to the pig farm. I don't know if it's an employee of a pig farm, but he often appears on the pig farm. ”

"What's unusual about him?" asked Mu Yuan.

Wu Yanhui frowned and said, "I always feel that he looks at me strangely. Also, when I went to the pig farm, he always approached me for strange reasons, some of which I thought were ridiculous. ”

Mu Yuan was silent for a few seconds and said, "Are there anything else abnormal?"

"Hmm...... This man has a bit of a ...... personality Well, how do you say that? I was only on the pig farm for two months during the summer vacation, and I only went occasionally, but I saw him get into arguments with other people twice. I still vaguely remember his expression at that time, and I had a crazy feeling. ”

Mu Yuan and Cheng Bin glanced at each other, and they could read a trace of excitement in each other's eyes.

This...... That's good news.

Comparing the information before and after, the person Wu Yanhui said and the murderer in this case are perfectly matched in many characteristics.

While this may also be a coincidence, the odds of a coincidence are too low for the situation at hand.

Then Mu Yuan asked some more about this person.

Although Wu Yanhui can't remember the other party's name, she can barely describe her age, approximate height or something.

After asking about these situations, the two of them could barely count in their hearts.

"Thank you, Ms. Wu, are there any other strange people?" asked Mu Yuan.

Wu Yanhui's expression was a little weird, what do you mean? Could it be that she looks like she is quite attractive to that kind of strange person?

"No, after all, I haven't been in my hometown for long. She replied in the affirmative.

Mu Yuan nodded and said, "Okay then, if Ms. Wu, you can contact us directly." ”

"Okay! ”

Mu Yuan didn't delay any longer, and got up to say goodbye to Wu Yanhui.

......

Mu Yuan and the others didn't even go home-uh, Mu Yuan didn't have a home in Xihua City, but Cheng Bin did! And the baby - they drove back to Fengtai County directly.

On the way back, Mu Yuan asked Cheng Bin to feedback the relevant situation to the Hu team, and asked him to arrange for someone to immediately find out the suspicious people who met the situation.

In fact, according to Wu Yanhui's description, it is quite easy to find people.

Seven or eight years ago, there weren't too many people in a village who had tricycles, let alone working on pig farms in tricycles, and it was estimated that there were only one or two people at most.

Sure enough, before Mu Yuan and the others returned to Fengtai County, a person had already been found on the side of the Hu team.

Not only that, but there is a lot of information that has been summarized.

"Chen Jiang, 32 years old, is now working in other places, and he went out more than seven years ago. Except for the occasional trip back for the New Year, I basically never came back. ”

"By questioning some old employees in the pig farm, it was determined that Chen Jiang had been driving a tricycle to deliver feed to the pig farm before he left his hometown to work. ”

"Chen Jiang is not an employee of the pig farm, but the pig farm hires Chen Jiang to deliver things, and the settlement is based on this. ”

"The reason why the pig farm hired Chen Jiang was also because of the conflict at the beginning of the establishment of the pig farm. At that time, Chen Jiang was making a lot of trouble, and in order to calm the situation, the pig farm promised to contract these things to Chen Jiang, who had a tricycle. ”

According to the memories of some veteran employees, Chen Jiang stopped driving a tricycle and went to work in a coastal city shortly after Yan Yunwei's resignation. ”

Knowing these circumstances, Mu Yuan breathed a long sigh of relief, if Mu Yuan was only thirty percent sure that the murderer was Chen Jiang before, then now this certainty has been increased to at least sixty percent.

It's good to be 60% sure that the murderer is identified, after all, there is no more ample evidence to prove all this, all ...... It's all just inference.

Although this inference is reasonable, the case belongs to the social sciences.

It is different from the natural sciences, which can directly arrive at the correct answer through reasoning, and the social sciences can also reason, but this reasoning ...... Believe it!

However, after having this big grasp, Mu Yuan also has the confidence to continue digging deeper.

With these, it's no problem to go on a business trip to meet Chen Jiang.

Of course, business trips are not just spoken, and you can't go out knowing a name.

This is also simple, after all, Chen Jiang has not completely cut off contact with his family, and he will come back every one or two years.

Quickly rushed back to Gaoliang Town to join the Hu brigade and them.

Seeing Mu Yuan, Team Hu said quickly: "Team Mu, about the situation in Chen Jiang's family, we just inquired about some more. His parents are still alive and he has an older brother. His brother is a big truck driver, and he has made a lot of money in Xihua City over the years. Originally, his tricycle belonged to his brother, and he returned it when he left. ”

Mu Yuan was a little helpless, according to his estimate, if Chen Jiang was really the murderer, then he would probably use this tricycle to pull out the corpse parts and bury them after he split the body.

To change to a normal case, this tricycle is used as a tool for committing crimes, and most of the traces and physical evidence can be extracted from it.

But now so many years have passed, not to mention whether there is any trace of physical evidence on it, even if it exists, it has long been lost.

"I think we can meet Chen Jiang's brother and maybe get some information. Mu Yuan said.

Hu Brigade said: "This ...... If Chen Jiang is really the murderer, and then his brother tells Chen Jiang the news that we have learned about the situation from him in advance, wouldn't that be a surprise to the snake? This will undoubtedly bring trouble to our subsequent arrests. ”

Mu Yuan said seriously: "The difficulty of this case is not to arrest people, but how to collect enough evidence to pry open the murderer's mouth." ”

Team Hu was stunned for a moment, and quickly understood the meaning of Mu Yuan's words.

I have to say that Mu Yuan's words are indeed to the point.

In any case, the murderer is there, and as long as the identity is clear, the chance of successful capture is still very high.

But if there is not enough evidence, in this case, even if Chen Jiang is arrested, if the other party denies it, the police can only release him in the end.

Although it is not necessary to collect enough evidence to go to Chen Jiang's brother first, there is some hope in the end, isn't it?

Besides, at times like this, it's not necessarily a bad thing to startle the snake.

If Chen Jiang really escaped because the police came to the door, it would also be very helpful for the police to interrogate the other party after they were arrested.

It didn't even take Mu Yuan to explain in too much detail, and Team Hu was convinced.

"I'll contact Chen Jiang's family first. Hu Brigade said immediately.

Mu Yuan said: "Let's let Murakami get in touch! Before we meet Chen Jiang's brother, we shouldn't behave too abnormally." If the other party is mentally prepared, it is difficult for us to ask for some valuable information. ”

Hu Brigade did not object.

At that moment, the Hu brigade asked the police station to get in touch with Murakami, and asked him to communicate with Chen Jiang's family and determine a specific time for the visit.

As a result, this question got a good news.

Chen Jiang's elder brother, Chen Xiong, is in Fengtai County.

Mu Yuan, who got Chen Xiong's contact number, rushed directly to Fengtai County with Cheng Bin.

By the time we got to the city, it was almost night.

It didn't seem like much had been done this day, but in fact, Mu Yuan didn't even have time to stop and sit and rest - handling cases, this is also a normal situation, not only Mu Yuan, but also any other police case is almost like this.

Before Mu Yuan and the others rushed back to Fengtai County, they had already learned where Chen Xiong was, so they rushed over directly.

Of course, this is just the situation on the surface, secretly, Mu Yuan has already sent Xiao Mao to secretly target Chen Xiong.

When they were about to meet, Cheng Bin dialed Chen Xiong's phone and expressed his request for an interview to the other party.

For such requests from the police, normal people generally do not refuse, and it is difficult to refuse, after all, this involves a homicide.

Chen Xiong is no exception, he himself has heard before that the police are visiting Gaoliang Town on a large scale, and he himself is also from Gaoliang Town, isn't it normal to meet and ask questions?

The place where the two sides met was also a teahouse.

"Mr. Chen, didn't bother you, did you?" asked Cheng Bin with a smile.

Chen Xiong really wanted to say that you disturbed me, but he couldn't say it after all.

"It's okay! Just a few friends get together for a meal, and it's okay if you don't go. Chen Xiong smiled.

Mu Yuan smiled slightly and said, "We know some of the situation, and we can't delay too much time." ”

"Cheng!" Chen Xiong took a sip of tea.

Mu Yuandao: "I heard that your brother was driving a tricycle to deliver goods to the pig farm in Ding Tao in the town?"

Chen Xiong nodded and said, "That's the case!"

"Why would the pig farm ask your brother to deliver the goods?" asked Mu Yuan casually.

In fact, this question is easy to attract hatred, but in fact it is a question of ten thousand gold oil, because anyone can be caught in this way.

Chen Xiong didn't think much about it, and said with a smile: "That's a long story! When Ding Tao first built the pig farm, several nearby villages were very opposed, after all, the pollution of this kind of large-scale pig farm is still very serious. Later, after negotiation, the pig farm also made some compensation, and my brother took over some small-scale transportation business of the pig farm. ”

"But why didn't he do it again?"
