Looking at the several faces full of curiosity in front of him, Mu Yuan smiled calmly.

At least it shows that this eldest sister Liu is not lying. ”

Team Yang was obviously stunned for a moment, and asked, "Just didn't lie?"

The two comrades from the police station were also surprised.

After all, it seems that it took so much effort to go to the other party's house and ask them face-to-face, just to prove that they were not lying...... It's too much fuss.

Mu Yuan could also see their thoughts, and said with a serious face: "Yes! But the conclusion of 'not lying' is not useless, on the contrary, it is useful. ”

After speaking, Mu Yuan didn't rush to get into the car, just stood at the door and said, "Sister Liu didn't lie, which means that his husband Wei Chengxiang really hasn't returned home, and he hasn't had any contact with his family." ”

"Yes, we've known this before. Deputy Director Huang was very surprised.

Mu Yuan smiled and said, "But don't you think it's abnormal?"

"What's not normal?"

"According to the information that our police have before, Wei Chengxiang fled with money, and the total amount of money is almost more than one million. But we just went to his house, and the duplex suite was worth far more than a million. Will the other party run away for the million?"

"This ...... We've thought about this before. But all kinds of clues proved that he did flee with the money, and as soon as the construction company above paid him, he went to the bank to withdraw cash, and then the person ran away. ”

"How do you know he's gone?"

"After he completed the withdrawal, there was a record of buying train tickets, and he did not tell his wife about this. According to our tracking, Wei Chengxiang did not take the train later, but he did drive away from Xihua City by himself. However, Dou Jun and the others reported the case late, and we could only trace the trajectory all the way, but after tracking more than 100 kilometers, we lost our trace. However, with this, it can also prove that he escaped with the money. ”

Mu Yuan didn't refute his words, and continued: "In addition, there is another doubt. From that eldest sister Liu, it can be seen that Wei Chengxiang still cares about his family very much, and he also has a son. Under normal circumstances, even if you are out of the house, you will occasionally contact your family. After all, people are emotional animals, and many things cannot be put down. ”

Brigade Yang said on the side: "What if...... Wei Chengxiang secretly had contact with his family?"

Mu Yuan smiled and said, "This is back to the question at the beginning! The reason why I came over to meet Sister Liu in person is to confirm this in person." In the end, it also proved that Wei Chengxiang did not have any contact with his family, which Sister Liu did not lie. ”

"How can you tell if he's not lying?" Brigade Yang was a little confused, wouldn't it be because of the simple conversation just now?

Mu Yuan smiled calmly and said, "Lie detection, to a certain extent, is also a language art. How to ask, how the other party answers, and what kind of look will be shown, all have deep knowledge. I've done some research in this area, and I've also seen how a person lies. What's more, I also know a little bit about psychology. Judging from Sister Liu's performance in all aspects just now, she ...... I really didn't lie. ”

Brigade Yang and the others were a little panicked in their hearts.

If you want to say that Mu Yuan's words are wrong, right? It doesn't make sense to say, because, generally speaking, this is the truth.

But if Mu Yuan's words have explained the problem of Team Yang just now, then ...... Basically not.

In fact, if Mu Yuan's words are put in another way, it can also be understood as an answer to the question of the Yang team: How do I judge whether she is lying or not, this is a technical job, you don't understand it, it's better not to say it!

"Of course, there is another important point: the skeleton we found at the scene was estimated to be between 1.71 and 1.75 meters tall through forensic examination. And just now Sister Liu said that her husband's height is 1.74 meters. ”

"Bones?" Deputy Director Huang was a little shocked, he didn't know about this situation yet.

Previously, the Chengxi Police Station was asked to investigate the relevant information, but it only said that it was related to a case of the Criminal University, and did not specifically say what the case was.

There are many cases that the Criminal University has been exposed to, and Deputy Director Huang doesn't have much thought to end it, but he never thought that this would actually involve a murder case - there are corpses, what is it if it is not a murder?

Team Yang paused slightly, and then briefly recounted the relevant situation.

After listening to this, Deputy Director Huang fell silent.

"Squadron Mu, do you mean this...... Wei Chengxiang, it's likely that he died three years ago?"

Mu Yuan was noncommittal, and said: "To verify whether our inferences are correct, DNA testing is the most direct means. ”

The other three policemen present did not say a word.

Then Sister Liu's family has been hard enough, if you hear that the person who has been waiting for many years has already become a dry bone, how worrying is this?

But if Sister Liu is not notified, how can she get DNA samples from her son?

You can't let this thing hang all the time, can you?

Team Yang suddenly looked at Director Huang and said, "Director Huang, I'm afraid I have to trouble you for this matter." ”

Director Huang turned his head to look at Mu Yuan, feeling a little resentful in his heart.

Why didn't you just tell the other party about it when you were at the other party's house?

It's a pity that Mu Yuan didn't plan to explain to him - can he say that his heart is too soft to see too bleak scenes?

Of course, there is another factor, that is, Sister Liu's son was not at home at the time, and even if he said it, it was impossible to do it on the spot.

......

Mu Yuan and the others returned to the Criminal Investigation Brigade, except for their line, the investigation of the case was almost still in place.

This is actually normal.

Whether it is an investigation in a hospital or a visit to various police stations, it is a needle-in-a-haystack investigative method, and unless you are lucky, you must spend time grinding hard if you want to have results.

As for Mu Yuan's case...... Well, this is a freak, a hanging, and cannot be judged by common sense.

Mu Yuan is also very clear about this, so many times he will not be in a hurry to ask others about the progress of the investigation.

When I asked, it felt like I was urging others, or it seemed like showing off......

For Mu Yuan, there are only two things that can be done now.

One is to wait, wait for the results of the DNA test. If the DNA of Sister Liu's son can match the DNA of the bones, then the identity of the deceased will be confirmed, and it will be a breakthrough for this case.

The second thing is to use the names of Wei Chengxiang and Zhao Huaimin to go to various hospitals and health centers in Pujin County to do reverse verification.

Judging from the current situation, if the deceased is Wei Chengxiang, then Zhao Huaimin must be very suspected of committing the crime.

As for the wallet, Mu Yuan was a little puzzled.

Mu Yuan felt that the wallet was very likely to be a suspect, but judging from the current situation, it was very likely that the note paper was left by Wei Chengxiang.

And the current indications show that Wei Chengxiang is a victim.

However, Mu Yuan still did not give up the idea that the wallet fell from the murderer.

If the wallet itself belongs to the victim, then it may be said that the murderer touched the other party's wallet when he harmed the victim.

This would also explain why there were no things like ID cards and bank cards in the wallet that were thrown away by the killers.

As for the invoice and sticky note, it may have slipped through the net and was ignored by the other party.

However, all this is just speculation, and Mu Yuan has not yet reached a conclusion on the facts.

But either way, it's always a good idea to look it up along this line.

Of course, the name on the list is not necessarily Wei Chengxiang or Zhao Huaimin, it may also be Wei Chengxiang's wife, Sister Liu, or his son, or some of Zhao Huaimin's relatives.

No problem...... It's just possible!

Or maybe it's nothing......

Mu Yuan told the Yang Brigade of his plan, and the Yang Brigade immediately made arrangements and deployments.

The investigation team, which had been running around various hospitals, had another task.

Time passed quite quickly, and it was soon evening.

Mu Yuan was about to beckon Lin Qing and Fan Yitong to go to the canteen of the Pujin County Bureau, when he just walked out of the office, but saw Yang Brigade walking out of another office.

"Squadron Mu, let's go, let's go eat out at night. ”

"This ...... Isn't that okay?"

"What's so bad. Brigade Yang said very straightforwardly, "I heard that Squadron Mu is very interested in food, so you can't come to our Pujin County, let's entertain in the canteen every day, right?"

Fan Yitong, who was following behind Mu Yuan, glanced at Team Yang, a little disdainful.

This guy can say pretty things!

is obviously interested in eating, but when it comes to his mouth, he becomes interested in food, and the style is suddenly different.

Mu Yuan was still a little hesitant......

Brigade Yang said: "Just eat a hot pot, buffet! It's not extravagant and wasteful." ”

"Okay then!" Mu Yuan was as good as a stream.

Soon, the group arrived at the hot pot restaurant mentioned by the Yang brigade, and he found that it was not only the captain, instructor and two deputy captains of the criminal brigade who were present, but also a deputy director in charge of criminal investigation.

After a meal, everyone was quite satisfied.

Mu Yuan is satisfied that he has eaten quite full, and the taste is not bad, and the reason why the people here in the Pujin County Branch are satisfied is because the money has not been spent much, and the effect has also been reflected.

Being able to establish a good relationship with the Mu squadron will be of great help to the cracking of criminal cases in the county bureau in the future - this time from yesterday afternoon to this morning, the cases that Mu Yuan helped solve with friendship can be seen.

When he was about to finish eating, Mu Yuan looked up and saw a person, an acquaintance.

Su Jinqiu, reporter of Su University.

"Officer Mu, I didn't expect to meet you here?" Su Jinqiu said with a smile.

"I didn't expect that either. Mu Yuan smiled and said, "If you had come early, I could have invited you to a meal, but now we are almost finished." ”

"If you really want to have this idea, I don't dislike it!" Su Jinqiu smiled like a little fox...... Essence.
