civil forensic

@@A team of security guards were arrested a few times. This action first scared Yuan Jiansheng.

Immediately afterwards, Yu Wenshu began to frantically answer the phone.

Yu Wenshu had expected it a long time ago, without any change in expression, he answered the phone calmly, explained a few words with similar formulas, then hung up the phone and waited for another round of calls.

Shen Yaoguo was actually similar, but he wasn't as calm as Yu Wenshu, so he found a place to hide, and answered the phone with a smile on his face.

The two of them were like two operators, each of them was hot on their mobile phones, and the frequency of picking up gradually became lower.

"Looking at the detachment leader from the outside of the office, I thought the detachment leader was strategizing, but when I entered the office, I found out that the detachment leader is just a microphone, a machine that answers the phone." Yu Wenshu didn't receive a new call for nearly 3 minutes, and finally Relieved, Xiang Jiangyuan smiled and shook his head.

Jiang Yuan understood very well: "Uploading and distributing is an intermediate link in strategizing."

When he was eating hundreds of meals in Jiangcun, he still looked at people's faces.It was because the people who were demolished later became too rich and went to college again, so this skill was gradually abandoned.

Yu Wenshu laughed out loud, as long as Jiang Yuan didn't have to step on his face, he would be very happy.

At this moment, Jiang Yuan was willing to say something pleasing to the ear, and Yu Wenshu's ear, which was scalded by the phone call just now, seemed to be healed.

"It's okay, just do what you want. When it comes to these key enterprises in provinces and cities, there will always be people who want to intercede. Those who intercede are okay, and some people still need to understand the situation... In fact, it is useless work. The investigation has entered into the environment of arresting people. At this time, interceding and understanding the situation, in my opinion, are all going through the motions. I will accompany you through the motions." Yu Wenshu hummed two sentences mainly to explain Jiang Yuankuan's situation . "

Jianyuan's parking lot security team has caught a lot of people, but in the next link, Jiang Yuan has to lock up some evidence.

Of course, Yu Wenshu believes that even those who are frightened and deceived should be able to catch a few people. However, looking at Zhang Xiang's appearance of refusing to scatter eagles when he doesn't see rabbits, he knows that this method must be quite difficult, and don't expect to be able to do so. Hold everyone down.

"The next step is up to you." Yu Wenshu was fully prepared for the cheerleaders.

Jiang Yuan had been making preparations just now, so he nodded at this moment and said, "Then follow the plan, let's take a look at the equipment they brought back."

Jiang Yuan himself is also trying to use different techniques to solve the case.

The combine harvester also needs to have a working order.

For today's case, Jiang Yuan felt that it is still necessary to fully use LV6's tool mark identification skills first.

LV6's tool mark identification skill, facing normal tools, the accuracy and speed of identification are top-notch.Basically, you can tell at a glance whether it matches the current case.

Moreover, because he is too familiar with the traces of tools, Jiang Yuan can write down the tools and traces involved in many files in one breath-although it is only a temporary memory, it also greatly improves the work efficiency.

If ordinary trace inspection is used to identify tool traces, the common practice is to observe first, not only with the naked eye, but also with horseshoe gold and a microscope.

In addition to looking for features, the purpose is to record the size, size, shape, outline, etc. of the traces. A more standard approach is to draw a schematic diagram of the features.

Jiang Yuan is equivalent to skipping these intermediate steps, and it is a many-to-many memory, recording the characteristics of multiple traces at the same time, and then comparing multiple tools.

The criminal science and technology center under Wanbaoming also sent trace inspectors to help at this time. Three young trace inspectors in their 20s, almost 30 years old, were just at the age of learning new technologies and methods. Faith almost collapsed.

"Team Jiang, there are still a lot of tool marks involved in the dossier here, why don't we find so many first?" A trace inspector flipped through the dossier, showed Jiang Yuan a few photos of the tool marks in it, and couldn't help saying .

After he showed Jiang Yuan the tool traces of more than a dozen cases in one breath, he began to doubt and be uncertain.

Can anyone really remember that much?
Jiang Yuan didn't bother to explain, so he said: "Then draw a schematic diagram of the characteristics to strengthen the memory."

The characteristic diagram is different from the characteristic points of the fingerprint. The fingerprint characteristic points are for the computer software and for the court to see, while the characteristic diagram of the tool trace is for oneself to see.

Therefore, the characteristic schematic diagram can be drawn very simply, and it does not need to be beautiful and realistic with a few strokes. It is enough to express the trace characteristics, or it does not matter if the trace characteristics are not displayed, as long as the person who draws it understands it
The.

Thus, the three trace inspectors from Changyang City saw Jiang Yuan's flamboyant and phoenix dance.

Speaking of which, Jiang Yuan still has the skill of sketching, but the only thing that can make sketching useful for drawing this feature diagram is the lines.

At the end of the drawing, Jiang Yuan even started to use a single line to draw the entire characteristic diagram.

The three young trace inspectors didn't dare to speak and didn't understand, so they just stared at Jiang Yuan's operation in a daze, and tried to support their crumbling skill tree.

"Found one. The warped indentation on A27 should be done by wire cutters from B109. Let's see what the case is."

When Jiang Yuan started to actually work on the case, the three young policemen were really stupid.

The so-called A27 is the traces that appeared in the representative dossier of the A series numbered by Jiang Yuan himself. B109 is the tool brought back by the criminal police, starting with B, numbered sequentially, and photographed sequentially. B109 also represents the number of the photo.

Hundreds of traces, hundreds of tools, really forced to remember, it's like a joke.

But for LV6's skills, sorting memory is just a child's science.

A trace inspector quickly took the photo of A27 and the physical tools of the photo of B109.

Just seeing that A27 is a lock bar for a sliding window, and there are obvious prying marks on the front and back, you know that Jiang Yuan is not guessing.

The three of them rushed forward involuntarily, and followed Jiang Yuan to compare the wire cutters represented by A27 and B109.

I saw that the width of the top of the pliers was the same, and the number of side teeth was also the same. After careful comparison of the concave and convex points, it seemed to be the same. The three people looked slowly and couldn't identify the same, but they couldn't find the wrong point. Explain the answer.

"How did you find this?" The youngest trace trace couldn't help showing a hint of longing in his eyes.This is a secret book of martial arts. Anyone who has mastered this kind of skill will be able to travel all over the world without fear.

While making records, Jiang Yuan handed over the dossier to Wang Chuanxing next to him, asking them to provide it to the interrogators, and at the same time explained: "There are more speculations about the prying marks. I saw the prying marks first, and then Among the tools I want to collect, which one can make prying marks, and then think about the similar size marks. In addition, there is one thing that can actually be paid extra attention to, which is the problem of static load.”

Everyone listened carefully to the first half of Jiang Yuan's sentence, and tried hard to memorize it
In the second half of the sentence, the eyes of the three young traces slowly lost their light.

The in-depth study of tool trace inspection is to study the function of force, such as common action force and reaction force, stress, external force...and very important force direction, force magnitude, contact relationship between point, line and surface, etc. Wait.

But as we all know, once it involves mechanics, whether it is theoretical mechanics, material mechanics, structural mechanics, fluid mechanics, elastic mechanics, plastic mechanics, damage mechanics, fracture mechanics, vibration mechanics, explosion mechanics, etc.

There isn't a good one.

"I'm going to get the photo." The young Henjian showed a sensible smile.

"I'm going to get the file." The slightly younger trace followed closely behind.

"I... will pour you some water." The adult medical examiner bent down and lowered his head, with a pious and well-behaved expression on his face.
