@@A number of security guards were arrested. This action first frightened Yuan Jiansheng.
Immediately afterwards, Yu Wenshu began to answer the phone frantically.
Yu Wenshu had expected it, and without any change in his expression, he picked up the phone with a calm face, explained a few words in similar clichés, then hung up the phone and waited for another round of calls.
Shen Yaoguo was actually similar, but he was not as calm as Yu Wenshu, so he found a place to hide and answered the phone calls with a smile on his face.
The two people were like two operators. They each dialed their cell phones until they got hot, and then the frequency of pick-up calls gradually became less and less.
"Looking at the detachment leader from outside the office, I thought the detachment leader was strategizing. When I entered the office, I realized that the detachment leader is just a microphone, a machine that answers the phone." Yu Wenshu didn't receive a new call for nearly three minutes.
He breathed a sigh of relief, smiled and shook his head to Jiang Yuan.
Jiang Yuan said very clearly: "Uploading and issuing is an intermediate link in strategizing."
When he was eating hundreds of meals in Jiangcun, he could still read people's faces. It was because he became too rich after being demolished and went to college that he gradually lost this skill.
Yu Wenshu laughed out loud. As long as Jiang Yuan didn't step on his face, he would be very happy.
At this moment, Jiang Yuan was willing to say something pleasant, and Yu Wenshu's ears, which had been perked on the phone just now, seemed to be healed.
"It's okay, just do whatever you want. When it comes to key enterprises in these provinces and cities, there are always people who want to come over to intercede. The intercessors are not bad, and some people still want to know the situation... In fact, it is all in vain, and criminal cases are all
The case investigation has entered the stage of arresting people. In my opinion, interceding and understanding the situation at this time are just going through the motions. I will go through the motions with you." Yu Wenshu hummed two sentences, mainly to explain Jiang Yuankuan's situation.
.
Many of Jianyuan's parking lot security team have been arrested, but in the next step, Jiang Yuan has to lock down some evidence.
Of course, Yu Wenshu believed that even by scaring and deceiving, he should be able to catch a few people. However, looking at Zhang Xiang's behavior, he knew that using this method would definitely be difficult, and don't expect to be able to do so.
He held everyone down.
"The next step is up to you." Yu Wenshu was fully prepared as a cheerleader.
Jiang Yuan, who had been making preparations just now, nodded and said: "Then as planned, let's take a look at the equipment and equipment they brought back."
Jiang Yuan himself is also trying to use different techniques to solve the case.
Combine harvesters also need to have a working sequence.
For today's case, Jiang Yuan felt that he had to make full use of LV6's tool mark identification skills first.
LV6's tool mark identification skills are superb in accuracy and speed for normal tools. You can basically tell at a glance whether it matches the current case.
Moreover, because he was so familiar with tool traces, Jiang Yuan could memorize the tools and traces involved in many files at once - although it was only a temporary memory, it also greatly improved work efficiency.
If it is a common mark inspection to identify tool marks, the common approach is to observe first, not just with the naked eye, but also with a gold hoof and a microscope.
In addition to finding features, the purpose is to write down the size, size, shape, outline, etc. of the traces. A more standard approach is to draw a schematic diagram of the features.
Jiang Yuan skipped these intermediate steps, and used 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 inspections to help at this time. Three young trace inspections in their twenties and almost thirty years old were at the age of learning new technologies and methods.
Jiang Yuan's belief almost collapsed.
"Team Jiang, there are still a lot of tool marks involved in the file here. Why don't we look for these first?" A trace inspector flipped through the file and showed Jiang Yuan several photos of tool marks in it. He couldn't help but say
.
After he showed Jiang Yuan the tool marks of more than a dozen cases at once, he began to doubt and be uncertain.
Can anyone really remember so much?
Jiang Yuan didn't bother to explain, so he said: "Then draw some schematic diagrams of the characteristics to strengthen the memory."
The characteristic schematic diagram is different from the characteristic points of fingerprints. The characteristic schematic points of fingerprints are for computer software and the court to see, while the characteristic schematic diagram of tool marks is for you to see.
Therefore, the characteristic schematic diagram can be drawn very simply, and it does not need to be beautiful and realistic with only a few strokes. It is enough to express the trace characteristics, or it does not matter if it cannot be expressed, as long as the person who draws it understands it.
.
As a result, the three Changyang City trace inspectors saw Jiang Yuan's dancing body.
Speaking of which, Jiang Yuan still has the skill of sketching, but when drawing this characteristic diagram, the only thing that can make sketching useful is lines.
Later in the painting, Jiang Yuan even started to use a single line to draw a complete schematic diagram of the features.
The three young tracers didn't dare to say anything, and they didn't understand. They just stared blankly at Jiang Yuan's operations and tried to hold on to their crumbling skill trees.
"I found one. The indentation on the A27 number should have been made by the B109 wire cutters. Let's see what the case is."
When Jiang Yuan started to actually work on the case, the three young trace investigators were truly fooled.
The so-called A27 is the trace that appeared in the A series of numbers compiled by Jiang Yuan himself to represent the traces in the file. B109 is the tool brought back by the criminal police, starting with B, numbered in order, and photographed in sequence. B109 also represents the number of the photo.
There are hundreds of traces and hundreds of tools. It's really like forcing me to memorize them. It's like a joke.
But for LV6 skills, categorized memory is just a piece of cake.
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, with obvious pry marks on both the front and back, we knew that Jiang Yuan was not just guessing.
The three people couldn't help but rush forward and follow 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 tooth lines on the sides was also the same. If we carefully compared the concave and convex points, they seemed to be the same. The three people looked at it slowly and couldn't confirm that they were the same, but they couldn't find the wrong point, and they almost had it.
Explain the answer.
"How did you find this?" The youngest Wenjian couldn't help but reveal a look of longing. This is a secret book of martial arts. If anyone masters this skill, he will be able to travel all over the world without fear.
While taking notes, Jiang Yuan handed the file to Wang Chuanxing next to him, asking them to provide it to the interrogators. At the same time, he explained: "There are more speculations about the pry indentation. I saw the pry indentation first, and then
Among the tools I have collected, which one can make pry indentations? Then think about the ones with similar size marks. In addition, there is one thing that you can actually pay extra attention to, which is the issue 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 men slowly lost their light.
To further study the tool mark inspection, it is to study the role of force, such as common action and reaction forces, stress, external force... and the very important direction of force, magnitude of force, contact relationship between points, lines and surfaces, etc.
wait.
But as we all know, when it comes to mechanics, whether it is theoretical mechanics, material mechanics, structural mechanics, fluid mechanics, elastic mechanics, plasticity mechanics, damage mechanics, fracture mechanics, vibration mechanics, explosion mechanics
None of it is good.
"I'm going to get the photos." The young Henji showed a sensible smile.
"I'm going to get the file." The slightly younger Wenjian followed closely behind.
"I...get you some water." The adult bent over and lowered his head, with a pious and well-behaved look on his face.
