Team Yang glanced suspiciously at the time on his phone.

Well, it's almost 11:30, and there's nothing wrong with having lunch...

Are you rushing back so anxiously just to fill your stomach first?

This operation...is very smooth!

"We won't eat!" Yang Battalion said immediately, "But... Where are you in Squadron Mu? I'll come and pay the bill for you."

"Then there is no need!" Mu Yuan said simply and hung up the phone.

Yang Bada was stunned for a moment, always feeling that his rhythm was completely inconsistent with this Mu Squadron.

Mu Yuan didn't tell the location, and he was powerless to pay the bill. He couldn't just locate where Mu Yuan was for such a thing, right? If so, then what's the difference between him and Mu Yuan's operation just now running back for lunch at the speed of Formula 1 car?

"Get everything into the technical room first!" Team Yang ordered.

Although it was a scene three years ago, a lot of things were retrieved, and even a piece of soil under the corpse was shoveled...

Of course, the most valuable thing should be the clothes worn by the deceased and the wallet.

Clothes and other things need further testing, but the wallet can be opened as soon as possible to view.

So after Brigade Yang gave the order, he immediately entered a technical room with the police officer carrying the physical evidence bag with the money clip.

Although this room is not a dust-free environment, it is also a relatively professional technical room.

The technical policeman opened the physical evidence bag and carefully took out the wallet inside.

The wallet is covered with sand and soil, but the wallet itself has no trace of damage. Its material is not genuine leather, so it should be a substance that is not easy to degrade.

Just as he was about to open the wallet, Yang Brigade suddenly stopped him: "Wait first! Wait until the Mu Squadron comes and then open it."

The technical policeman was obviously stunned for a moment, and he was a little confused about what Team Yang meant...

Isn’t it a professional thing for technical police officers to conduct trace physical evidence inspection? He has a specialty in his profession. It is true that Mu Squadron has strong ability to investigate and solve cases, but it does not mean that he is also very strong in trace physical evidence inspection!

It’s not a reason why this technical policeman had such an idea. After all, Mu Yuan saw the fingerprints with his naked eyes and saw the subtle differences in the footprints, which were magical, were not known to everyone.

The technical policeman was silent for a moment and couldn't help but say, "Captain Yang, don't you need it? This kind of trace physical evidence inspection process is like this, and everyone will be the same."

Team Yang still insisted on his own opinion and said, "Let's wait a little longer!"

Team Yang knew more about Mu Yuan’s affairs, and Mu Yuan left him with a deep impression just now. Although it seems quite unrestrained in some things, his professional ability is indeed impeccable.

What's more, the Gong Detachment had just explained to him on the phone, asking them to listen to Mu Squadron's opinions on this case.

In this case, if you listen to Mu Yuan’s opinions more, even if something goes wrong, he will not be responsible, right?

The technical policeman had to put down the tools in his hand first and sat helplessly on the chair next to him.

Not long after, Mu Yuan and the other two came to the technical room together. When they entered the bureau, they had already asked the relevant personnel, so they directly found the physical evidence laboratory where Team Yang and others were located.

"Captain Yang, are you... okay?" Looking at the three people who were bored in the room, Mu Yuan couldn't help asking.

Team Yang quickly stood up, smiled brightly, and said, "Mu, I think you may be more professional in this regard. This wallet is one of the few evidence left on the scene, and it is likely to be related to whether the case can be solved, so I want to invite Team Mu, you come..."

Team Yang didn't say the following words, but Mu Yuan already understood them. He smiled and said, "Okay!"

After saying that, Mu Yuan took a pair of gloves from the side, put them on skillfully, and then began to fiddle with the wallet.

Mu Yuan's movements were very light, like a lover's hand...

Opening a wallet itself does not have any technical content. Whether it is done by using the conventional method of opening the wallet or using a destructive method, it is very simple.

However, since the wallet has been left in the wild for unknown amount of time, there is serious adhesion inside, it is very important whether the items inside will be damaged during the prying process.

At this time, whether you can sense the force feedback from the wallet through your hands, and judge what actions to take through the subtle differences is a test of your skill and talent.

This is a men's 2-fold horizontal wallet, Mu Yuan first gently opens it.

All the clips inside are intact.

However, Mu Yuan had great hope but did not find a card, no bank card, ID card or membership card.

If the position of the wallet falling is not too distinctive, and by analyzing the degree of destruction of the wallet, it can be roughly determined that the time it exists in the wild is almost the same as that of the bone, Mu Yuan almost doubted whether the wallet was left behind by the murderer.

Generally speaking, it is normal to have no money in your wallet, but you basically have cards!

There is not a single card in this wallet, which is a very directive feature.

Of course, Mu Yuan could see at a glance that there were no cards in these card holders, but he could not guarantee that there was nothing else in the card holder. He needed to check every place in his wallet where things could be stored.

The way he is now taking is to open it in a destructive way.

Of course, the destructiveness here is not to tear the wallet apart randomly, but to carefully dismantle it along the suture of the wallet with a blade, layer by layer.

Soon, the first layer on the right side of the wallet was cut open, and Mu Yuan gently pulled it, and the interlayer of unknown material was separated.

It's empty inside!

Then the second floor...

This time it was not empty, there was a photo inside... He could see that this was a photo because the material and size of the paper should be a photo, not the picture on the photo.

Because the time is too long and the environment in which it is located is far from dry, the photo has been spent, and the portrait in the photo cannot be seen at all.

Not only Mu Yuan was a little disappointed with this result, but the people watching the other side were also very disappointed.

If the portrait can be seen clearly in this photo, as long as the wallet was indeed the murderer, the case would be almost broken.

Unfortunately, ideals are full and reality is skinny.

Mu Yuan continued to cut the third floor on the right!

The things inside came into view, and it was a piece of paper that was folded in a mess.

Due to the relationship between time and environment, the paper is already a little wrinkled and the text on the body is blurred.

Mu Yuan used tweezers, blades and other tools to take off the drawing with great care, and then slowly took apart the folded paper ball with meticulous effort comparable to embroidery.

Although Mu Yuan was very careful, the adhesion of the paper was indeed too serious. During the disassembly, it was inevitably damaged, and the whole process took seven or eight minutes.

Looking at the piece of paper the size of a palm in front of him, Mu Yuan fell into deep thought.

The others also came closer to observe, as if there was a huge secret hidden on it.

"This... seems to be an invoice issued by the hospital's payment, the color is light red, and it should be the couplet held by an individual." Yang Battalion murmured.

"It's a pity that the handwriting is too blurry! I can't see the patient's name." Lin Qing sighed.

Mu Yuan pointed to a corner seriously and said, "Look here! This is the invoice time. From the position, it should be the year. The last number can be roughly distinguished, which is 6. Judging from this, the invoice issuance time will not be more than four years. Although the number cannot be seen in the month column, it can be seen that it is a double digit number. Then this time can basically be determined to be 10, 11, and 12. The last "day" column is a double digit number, and the last number should be 1."

"There is also this seal. Although the specific text cannot be identified, the number of text on the seal can still be counted. We can conduct screening across the county, find out the hospitals and health centers that meet the conditions, and then lock in the target range according to the time above."

As soon as Mu Yuan finished speaking, Team Yang frowned and said, "Mu Squadron, this workload is too large, right? And now we can't determine whether this wallet was really left by the murderer or the victim. Is it worth spending so much energy on it?"

Mu Yuan said: "This wallet is probably the suspect's. I have a basis for this judgment. First of all, the time when the wallet fell on the scene is basically consistent with the time of the deceased's death, and the time on this hospital invoice also verified this point. Secondly, I had climbed up the cliff and observed carefully. There was still a wasteland forest above the cliff, and there were still two or three hundred meters away from the road. Under normal circumstances, no one would go to the edge of the cliff for a year or two, let alone the wallet was left."

Team Yang was silent. In fact, he knew that the wallet was probably the one that the murderer had left behind, but according to the operation Mu Yuan said just now, the scope of the investigation was too large! It was almost impossible to complete the task.

But Mu Yuan didn't say anything, but continued to cut the left part of the wallet.

Layer layers of mezzanine were pushed apart.

The first floor is still nothing!

The second floor, also not.

To be honest, Mu Yuan was also a little confused at this time.

He himself knew very well that according to the method he had just mentioned, the workload was indeed too large and the operability was not strong.

The reason why he proposed this method was to find new clues and further narrow the scope of the suspects.

But if you can no longer find valuable things in this wallet, it will be a little troublesome.
Chapter completed!
