National Forensic Doctor

Qi Changye's body, which had just turned halfway, turned back in parallel as if pressed by some mechanism.

"Um... do you have any news to update?" Qi Changye's memory is very good, to the extent that he can recall the appearance of his classmates in junior high school. The scene where Jiang Yuan updated the news before was even more vivid in his mind.

Jiang Yuan picked out a few photos, spread them out on the table, and said, "I'll show them to you."

While speaking, Jiang Yuan pointed to a photo showing the lock of a rolling shutter door and said, "This rolling shutter door was pried open with special tools."

Then, Jiang Yuan put two photos of ground locks in a row and said: "You can see from here that the lock of the rolling shutter door is made of a self-made Z-shaped steel plate with a jack. It's open."

"Have you encountered similar cases?" Qi Changye was surprised.

"No." After Jiang Yuan calmly denied it, he said: "That's why I said it is Z-shaped. This can be seen from the marks on the ground. In fact, the principle of using a jack to pry rolling shutter doors is the same, similar to a crowbar. Likewise, this suspect has just fixed this kind of lock-picking equipment and should be quite proficient."

Qi Changye was confused when he heard this.

Of course, he doesn't have the skills to identify trace tools at LV6, not even at LV1, so it's natural that he can't understand.

Jiang Yuan looked like this, pulled out a piece of paper, drew a force analysis on the spot, and said: "You can show it to a familiar technician. The characteristics of the marks left by the jack to pry the rolling shutter door are due to the upward force F. The lower edge of the rolling shutter door will be squeezed and deformed by the Z-shaped steel plate, and you will see different traces here..."

"To distinguish whether it is a jack or a crowbar, the indentation of the jack's base is usually on the outdoor ground outside the rolling shutter door. It cannot be seen in the photo. It may have been cleaned. However, there are no traces of the crowbar inside the door. The crowbar marks are usually difficult to clean, so if there are no crowbar marks, it can be concluded that it was opened by a jack.”

What Jiang Yuan said was a little convoluted, but Qi Changye understood it easily.

Moreover, Qi Changye also asked emphatically: "That is to say, the only two ways to pry open the rolling shutter door are the jack and the crowbar?"

"Judging from the marks on the rolling shutter door, generally speaking, there are only two types. Especially the deformation of the lower edge of the rolling shutter door. There must be undulating pits in the indentations. These mutual positions can reflect the Z-shaped steel plate. Characteristics of the end face.”

When Jiang Yuan said this, he said in a positive tone: "If you can find this homemade tool and examine it with a microscope, you can definitely confirm that it is the same!"

When Qi Changye heard this, he didn't care about the technical reasoning. He slapped his thigh and said, "I understand. I'll go find this homemade tool right away. Is this person a professional at stealing rolling shutters?"

"It's possible." Jiang Yuan agreed.

They are all proficient enough to make their own tools, and it must be for the purpose of using this tool more often and conveniently. Therefore, it is not wrong to say that this thief is a professional in stealing rolling shutters.

Of course, there must be more than one thief with similar preferences. Even in a place like the capital, there may be people from all over the country making a name for themselves, but there are definitely not many thieves who are good at using Z-shaped homemade tools.

Ordinary people may never come into contact with this kind of person in their lifetime, and even people in the world may not know the status of their homemade tools, but there are always people who know.

To find information in this area, detectives like Qi Changye or Tao Lu have plenty of ways to find it.

Qi Changye was in high spirits. After thanking Jiang Yuan again and again, he hurried away. As he walked, he took out his mobile phone and quickly sent a few messages.

The corridor was very quiet, and the clicking of keys was very rhythmic, like the sound of the God of Death dancing to a disco.

Tao Lu watched Qi Changye's back disappear, closed the door again, turned to Jiang Yuan, shook his head, and said, "You spoke too quickly. This kind of case is actually not that urgent. Just ask for news or something. That's fine." It’s only a few days, don’t be in a hurry.”

Jiang Yuan didn't react for a while: "Because Qi Chu said he would update the news at any time..."

"You can update the news with Lao Huang first. Don't you seem to be updating in a timely manner when you are here with me?" Tao Lu complained in his tone, with a hint of sadness, and taught Jiang Yuan how to do things.

Jiang Yuan laughed twice and said, "I'll tell Political Commissar Huang, but this is just a theft case."

"The devil knows what is connected to the theft case. As for the case of our criminal police, the burglary case can also be solved along with the theft case... Don't be embarrassed just because of his identity. What, can you do it for free if the confidentiality level is high? ? If you have the ability, you can use your own resources, right? When I first started working, I even exchanged canned food with the submarine soldiers. The soldiers at the radar station had a tooth ceremony, and they also talked to the forest police in a good voice... "

Jiang Yuan thought it was different. Then he thought about it and decided to leave it to Huang Qiangmin to think about it.

Looking at Tao Lu who was exuding a hint of resentment, Jiang Yuan took out his cell phone on the spot and said, "Then I'll call Political Commissar Huang."

"You go ahead." Tao Lu smiled, turned around and picked up the veteran cadre cup. The porcelain jar was straight, like intestines, which warmed people's hearts.

Jiang Yuan dialed the phone and quickly explained the situation.

Huang Qiangmin listened carefully, said "Yes" and said: "This is indeed a new situation. Yes, I will talk to the relevant authorities later. He knows more about this. Give the phone to Tao Zhi."

Jiang Yuan handed over his mobile phone as instructed and said: "Tao Zhi, our political commissar Huang wants to talk to you."

"Yeah." Tao Lu took the phone and said, "Old Huang, I found that you are a bit unreasonable... um, uh uh, uh?"

A few minutes later.

Tao Lu handed the phone back to Jiang Yuan and said: "I have hung up. If there is another case with Qi Changye, I will help you communicate. I guess the case will be brought over. Who can eat such good fat meat without smacking their lips? Yes, cough... I mean, Qi Changye's case must also be coordinated and arranged, and we can't just let him get it done when he comes."

Jiang Yuanquan pretended not to hear the middle part. As the son of the richest man in Jiangcun, Jiang Yuanquan had long been accustomed to cooking Tang Monk meat.

Jiang Yuan just explained: "It's because the scene in the photo is more obvious. Moreover, just looking at the photo, it is relatively simple."

The difference between one-stop solutions and reminders of key issues is quite big.

Tao Lu said "yes" and said: "In short, if Qi Changye comes to you again, you can contact me and Lao Huang. Like today, there is no need to lose the answer in such a hurry."

"Okay." Jiang Yuanyuan was a little obsessed with Tao Lu, so he explained: "We are usually willing to do one or two cases for the new unit."

"It's a good strategy. After eating the fine chaff, everyone will feel the difference if they go back to eat weeds..." Tao Lu said, seeming to have thought of something, and fell into silence for a while.

After a long time, Tao Lu sighed and said, "Forensic Doctor Jiang, have a good rest today. Let's choose a case with Liu Sheng tomorrow. I have communicated with Lao Huang."
