Team Yang may have seen Mu Yuan's abnormal performance, and also came over.

"Squadron Mu, did you find anything?" he bowed, his voice tinged with a hint of hope.

Mu Yuan squatted there, pointed to the ground, and said, "Look here!"

Team Yang was stunned, and then squatted down, following Mu Yuan's fingers, looking at the place that was originally covered by the back of the bones.

The dark soil with the characteristics of the forest, because it is covered by bones, and the debris of the previous leaves has fallen directly on the corpses, which has long been cleaned up, making this area a little cleaner than the rest of the place.

The earth is mixed with rotten branches, and there is a smell of decay.

Team Yang said with some uncertainty: "This soil ...... It's nothing special, isn't it? After being crushed, you can't see the sun, that's how it is. ”

Mu Yuan had no choice but to point his hand forward, almost poking it on the soil, and said, "Take a closer look, what is this?"

Team Yang leaned down and got closer......

"It's dirt...... Sand...... This grain of sand ......" Team Yang's eyes suddenly widened, "This is the river sand ......"

After saying that, Team Yang immediately looked around......

Almost staring at each other, Team Yang found the answer they wanted.

There is a difference between river sand and normal sand and gravel, which anyone who has seen river sand can tell.

And here, only the area where the bones remained had river sand, and the rest was all normal dirt or mountain gravel.

What does this mean? It means that this kind of river sand did not exist here, and it was "brought" by the deceased here.

Mu Yuan saw that Team Yang saw the clue, and then said: "It should be adhered to the deceased's clothes, because I found that there are also such sand grains on those fabric fragments." ”

"The deceased had river sand stuck to his clothes before he died. Team Yang fell into deep thought and said, "But we don't have a sand quarry in Pujin County that mines river sand, and the only explanation for his contamination with river sand is that he has entered a certain construction site." Moreover, it shouldn't be too far from here. ”

Fan Yitong, who was standing on the side, followed and said: "It may also be that after being killed, someone hid in the canal sand and pulled it over." ”

"You mean it'...... He killed?" Team Yang frowned.

If it is a suicide, even if the investigation is clear, it is just an unnatural death, but if it is a homicide, the nature is completely different, it is a homicide!

But if it was concluded that the deceased was killed by him based on these river sand alone, Team Yang felt a little unreasonable.

Fan Yitong couldn't see the hesitation of Team Yang, and immediately repeated what Mu Yuan said in the car just now.

However, he didn't put gold on his face, saying that this detail was discovered by the Mu team......

After hearing this, Team Yang couldn't help but carefully recall the state of the corpse just now, and his eyes became brighter and brighter!

The reason why his eyes are getting brighter and brighter is not because he is happy to hear that this is a murder, but because he gradually touches the truth.

As a criminal police officer, the thirst for the truth is almost instinctive.

"Squadron Mu, it seems that your talent and ability in solving cases are indeed worthy of your reputation!" After being excited, Team Yang sighed.

Mu Yuan pursed his lips and smiled, "It's okay!"

Brigade Yang understood Mu Yuan's answer as modesty!

"Squadron Mu, what is the direction of our reconnaissance next?" Since there was a big guy in front of him, Team Yang didn't bother to think about it, and asked directly.

Mu Yuan said: "First of all, we have to find out the time of death of the deceased. ”

Although it is impossible to be accurate to the day, if you extrapolate to a certain month or half a year, you are still very sure. Brigade Yang said.

Mu Yuan was not surprised by this.

After all, in this kind of exposed situation, the ossification of white bones is very rapid, and it can turn a fresh corpse into white bones in about a month. However, the evolution after becoming a white bone becomes a long time, and to determine this time, it is necessary to analyze the bone with an instrument.

In addition, the degree of decay of the clothes can also be used as a basis for judgment.

"After determining the time of death of the deceased, we can use this point in time as a benchmark to conduct a survey of the surrounding area...... By the way, have you checked, have there been any cases of missing people in your county in recent years? ”

Yang Brigade said: "It's being investigated now, but the results didn't come out so quickly." If an adult man is missing, it is difficult to file a case without certain evidence. But...... I estimate that even if there are people missing in the past few years, it is unlikely that there will be too many, and starting from this aspect can be a way to determine the identity of the deceased. ”

Mu Yuandao: "To determine the identity of the deceased, you mainly have to rely on DNA, which is the most convincing and efficient way. In addition, cranial reconstruction can also be done, which can also be used as a reference. ”

Brigade Yang was a little unsure, turned his head to look at another policeman next to him, and asked, "Forensic Doctor Du, can you still make DNA from a corpse that has been dead for several years?"

The Du forensic doctor said: "This is a completely white ossified bone, and the bone itself cannot be made into DNA, it depends on whether the medulla in the bone can be extracted from DNA." If the skeleton had been buried in the soil, DNA would have been extracted, but since it was exposed, the chances of success were relatively low. But...... You can still give it a try. ”

Mu Yuan glanced left and right, and said, "Judging from the environment here and the state of that skeleton, the chance of making DNA is still quite large. ”

Team Yang looked at Mu Yuan in a daze and asked, "Squadron Mu also knows a lot about forensic technology?"

"It's okay!" Mu Yuan said calmly, "I have dissected a corpse before, just a few weeks ago, in Qingyu County. ”

"The murder and dismemberment case in Qingyu County?" Team Yang immediately remembered that case.

Although it is not a county, the case in Qingyu County is of a bad nature, and it has a certain influence in the city, and with Mu Yuan's reputation, basically everyone in the city's criminal investigation line knows about that case.

But...... They didn't know that Mu Yuan was also involved in the dissection at that time, and he also came up with key conclusions.

Mu Yuan nodded, and said solemnly: "That's the case! There was some controversy in that autopsy, and then I invited an expert over, and this expert agreed with my point of view, and in the end, the facts proved that my argument was correct." ”

Brigade Yang was surprised.

Although Mu Yuan's tone was very calm, the content of his words was not ordinary at all.

At least it shows that Mu Yuan is no worse than ordinary forensic doctors in the field of autopsy, and even more awesome.

Although the autopsy is only a part of the forensic work, this line of work is extremely professional, how did Mu Yuan get in?

To be honest, for this question, Team Yang really wanted to ask, but considering that Director Feng of the Municipal Bureau was also at the scene at that time, if he really had questions, it is estimated that the Feng Bureau asked at that time, and he is a little nosy to open this mouth now.

"Squadron Mu is really an all-rounder on the criminal investigation front!" said Team Yang with emotion again.

Mu Yuan smiled and said, "I'm still studying hard!"

The corners of Team Yang's mouth twitched, and he glanced at several subordinates next to him, and there was a hint of hatred in his eyes: Everyone else is so awesome, and they are still working so hard, look at you again? Team Yang has an urge to cry.

But soon, the mentality of the Yang brigade returned to normal!

After all, a person like Squadron Mu has produced such a person in the entire Xihua City for so many years, and even ...... There is only one in the whole country.

You can't use the standard of genius to demand everyone, and a leader with this kind of thinking is definitely not a mature leader.

"Squadron Mu, what else do you need to do at the scene?" asked Brigade Yang.

Mu Yuan glanced around, especially the cliff in front of him, and he took a closer look.

The cliff is almost seventy or eighty meters high!

This is not the same concept as the cliff in film and television dramas, which are often hundreds of cliffs and abysses in film and television dramas, how can there be so many dangerous places in reality?

And the cliff in front of you also has something in common with the Baizhang cliff, for example, if a person falls from it, he will definitely die......

Mu Yuan pointed to it and said, "I'll go up and have a look!"

Team Yang said: "Then let's go up together, let's go over there......"

Without waiting for him to finish, Mu Yuan said casually: "No need!"

Then I saw him take a few steps forward, stretched out his hand to support himself on the cliff wall, then turned back and grinned, and said, "I'll go up and have a look, and I'll come down soon." ”

After speaking, before everyone could react, he had already rushed out of the cliff like a monkey.

"(#'O′)!" Brigade Yang exclaimed in horror, "Squadron Mu, what are you doing?"

Mu Yuan used his limbs together, constantly climbing upwards, and at the same time responded: "Team Yang, don't worry, this cliff is much easier to climb than a building." ”

Originally, Fan Yitong and Lin Qing were also shocked and wanted to speak out to stop their squadron leader.

But as soon as Mu Yuan said this, they dispelled this idea again.

Although the news about Mu Yuan climbing the building twice to save people was not widely spread in the Public Security Bureau, there was gossip.

Especially on the side of the Serious Crime Brigade, many people have heard some rumors.

Now that Fan Yitong and the others heard Mu Yuan's words again, they became more and more sure of this matter.

Is it okay for a person who can climb even the walls of a bare building to climb this cliff?

Although the cliff is extremely steep and the slope is not much different from that of a building, the flatness is certainly not comparable to that of a building.

The uneven stones on the cliff wall, the cracked cracks, and the strangely shaped small trees growing in the cracks of the rocks are all the bearing points for Mu Yuan to climb.

And Mu Yuan's actions also proved that what he said was true, just at the mouth of the conversation, he had climbed up four or five meters.

The distance of four or five meters is not high, but the Yang brigade wants to stop ...... I can only think about it, he can't take down Mu Yuan with a gun, right?

Of course, in fact, even if Mu Yuan hadn't climbed up the cliff yet, Team Yang might not be able to stop it.

Ask for a monthly pass!
