I know a lot. Mu Yuan smiled very casually.

Cheng Bin nodded on the side and quipped: "This is the truth! From climbing mountains and walls to going down to the sea to fish, the Mu team is top-notch." Let's just say that this swimming, if the Mu team goes to the Olympics, it is estimated that the gold medal will not have anything to do with those athletes. ”

"I think so too. The corners of Mu Yuan's mouth rose slightly.

Lin Qing's eyes widened as she looked at the two men......

Do you still want a face?

But after all, the other party is a leader, she is a little new, dare to say anything, so she has to turn her head and pretend not to hear.

Fortunately, Mu Yuan didn't "brag about himself" anymore, he took Cheng Bin and Lin Qing and walked around the periphery of the community.

This time, Mu Yuan did not use the Time Rewind Charm, at least not for the time being.

The upgrading of criminal psychology portrait technology to the master level has greatly improved Mu Yuan's reasoning of criminal behavior, and he wants to verify the theory in his head in practice, which is also a way of self-improvement.

Of course, Mu Yuan didn't look at anyone blindly, he also explained what he saw and thought very systematically to Cheng Bin and Lin Qing.

Maybe some other skills, such as the grandmaster-level smell identification technique, cannot be learned by others, but like the criminal mind profiling technique, it can still be comprehended.

Through the analysis and explanation of actual cases, it is much stronger than simply reading books, and it is also helpful for Cheng Bin and others to improve their ability in investigation.

This is also in line with Mu Yuan's original idea, to cultivate a group of shrewd and capable subordinates, which will not only help to combat illegal and criminal activities, but also help him obtain chivalrous points.

In this process, Cheng Bin listened to it with fascination, and some theories made him pause.

In fact, there are things about psychology that you will feel very mysterious if you have not been exposed to them, but once you talk about them, you will have a sense of transparency that is so original.

Especially an old criminal investigator like Cheng Bin, who has been in contact with countless cases before, is even more thorough.

Lin Qing's situation is worse, Xiao Mengxin, it's understandable.

Mu Yuan didn't force this.

Anyway, how much others can learn from their own teaching, that's the other party's business.

After turning around, they stayed in more than ten places, analyzed the wall, surrounding environment, and monitoring layout of each place, and finally Mu Yuan stayed at a wall near the street.

At the foot of the outer side of the fence is a green lawn about four meters wide, which is now in early summer, and it is often crowded with people sitting or wading in the shade at night.

Beyond the lawn is the sidewalk, and beyond is the road.

There are surveillance on both sides of the road, even at forks in the sidewalk that run to either side.

By looking at the angle of the monitoring probe, it can be determined that the surveillance screen does not completely cover this section of the road, and this is also confirmed by Fan Yitong.

Of course, similar situations are not unique around the community, and the reason why Mu Yuan pays the most attention to this place is naturally due to a combination of many reasons.

"First of all, we can conclude that the suspect must have arrived at the scene by car. ”

"In today's city, it is unrealistic for a car to go to a remote place without being noticed, although many people subconsciously think so, but in fact it is the opposite, if you want to really hide, run on the road with a lot of traffic, it is the best choice. This is also the reason for the great hidden in the city. ”

"It's clear that this avenue meets such standards. Even in the entire Xihua City, the traffic volume of this avenue can be ranked. ”

This is just a corroboration of what Mu Yuan said, and what really made him stay here was the most important reason - the wall.

This is a Western classical style wall, off-white.

The fence is a serious wall, but there are some inconspicuous traces on it.

This was discovered by Mu Yuan after careful observation.

Even in the most high-end community, it is impossible to wipe a wall like this often, after all, it is thousands of kilometers long......

Therefore, it is inevitable that there will be dust on it.

It's just that because of the color of the fence, the marks on it look very inconspicuous.

In other words, it is a normal forensic technician, unless you look closely inch by inch, it is difficult to find traces on it.

But Mu Yuan is different, don't forget that he just got an expert-level skill upgrade card, and now his trace detection skills have reached the expert level.

At this level, although it cannot be said that the eyes are like gods, and the detection of all traces is as powerful as the master-level fingerprint observation technology, it is still easy to find the imprints formed by directly destroying the dust surface.

"You look at the mark, and it's clear that you're climbing over the top edge of the wall with both hands. Judging from this trace, there should be two suspects. ”

Not to mention Cheng Bin, even Lin Qing could see that this was the trace left by the two people climbing.

"From the comparison of the dust covering this trace, it can be determined that the act of climbing the wall occurred within 10 days, which is basically consistent with the time of the crime. As long as nothing else, this is where the suspect entered the community. ”

Cheng Bin's eyes flashed and he asked, "Then what should we do next?"

"Both sides of this section of the street, whether it is a sidewalk or a road, are blocked by surveillance. Therefore, the suspect must have left a video record in the process of entering here. Now, we need to find these images and follow the trail. When Mu Yuan spoke, there was a strong confidence in his tone.

"Then we'll go back now?" Lin Qing asked.

Mu Yuan said: "Of course!"

......

The process of accessing surveillance is very smooth, but it is not easy to check the surveillance and find the suspect from the massive video data.

Mu Yuan estimated that if he was willing to take the time, with his current observation ability, it should be no problem to find the target from the video.

But what he lacks is time, or rather, he doesn't want to spend too much time on a case.

So, he cheated again.

However, since the traces left by the suspect have been found before, it is easy to locate the passage time of the suspect, and then calculate the time when the suspect entered and left the street, and the target can be found smoothly.

A car, too ordinary to be ordinary, belongs to the kind that will not attract attention if it is thrown in the pile.

As the car approached the section of the fence where the traces remained, a sudden brake stopped, and the two men got out of the car with great speed.

The car didn't make any stops, and drove away with a foot of gas.

The time, however, was in the evening.

Who would have thought that the suspect would appear on the periphery of the crime scene in the evening? And after getting out of the car, it has been in the blind spot of this surveillance.

And because of the large flow of people on this street, these two people have been wandering along this road, and no one has paid attention.

It wasn't until late at night that they climbed through the fence.

The whole process of theft did not take too long, which shows that the technical unlocking methods of these two people are indeed very slippery - although they are a lot worse than themselves.

And after they came out, they came out stuck in time, or the car, without any time wasted, and left the scene directly.

The process is already clear, and it is easy to look at the monitoring again.

As for explaining to others how he judged this car to be a suspect vehicle, is this a problem for Mu Yuan?

In terms of the comprehensive strength of investigation and case handling, he is at least a master now, if not a grandmaster. As for the ability to talk nonsense, he may not be able to reach the master level, but the expert level is still no problem.

"Look at this car, do you find anything wrong?" asked Mu Yuan, pointing to the black sedan that passed through the traffic checkpoint at the intersection in the early morning.

Cheng Bin did not answer immediately, but carefully compared the photos and videos of the car passing through the two intersections.

Lin Qing looked at it for a few seconds and said, "This section of the road is about two hundred meters, and at this speed, the middle ...... It shouldn't have stopped, right?"

Mu Yuan said: "Don't you think the speed of this car is very slow?"

Lin Qing said: "This may also be a novice driver." ”

Cheng Bin suddenly said seriously: "Lin Qing, in handling the case, we can't make excuses for any suspicious situations we see, but we should suspect the worst." Otherwise, the case will not be handled. ”

"Uh......" Lin Qing seemed to be thinking about the meaning of Cheng Bin's words, "I understand." ”

Cheng Bin nodded, his eyes were still wandering on the two videos, and after a while, he suddenly said: "Team Mu, I can see it!"

"Oh, what do you see?"

"The car deliberately slowed down when it passed through these two monitoring areas. However, when it is about to drive out of the monitoring range, the car should have an acceleration. I suspect that they did this in order to smooth out the time difference caused by parking in the middle and confuse the judgment of our investigators. ”

Mu Yuan nodded, and said with some emotion: "This is a group of habitual thieves! And the anti-reconnaissance awareness is very strong. ”

"Brother Fan, you can call up all the passing information of this car that day. Mu Yuan commanded.

Fan Yitong, who was sitting in the seat, immediately executed.

When a picture was presented, all four of them stared at it with wide eyes.

In the course of this day, the car left more than 100 pieces of trajectory information.

Looking at the photos one by one, they quickly noticed that something was different.

"The car passed down the street once in the evening. ”

"Looking at this photo, there are obviously two people sitting in the back row, this is the afternoon photo. But look at this, it's night, and there's no one sitting in the back row. ”

"Yes, this is a picture around 5 a.m., and the people in the back row have reappeared, and they are all still in the same clothes. ”

Although in most photos, it is impossible to see whether there are people sitting in the back row through the front windshield, there are always one or two monitors, because of the angle or lighting, you can see some clues.

Before contacting them, things seemed to be more clear.

Ask for a monthly pass! This little wish will be fulfilled......
