parking.

Turn off the heat.

When you push the door to get out of the car, the door can be opened to the maximum without touching the car body next door.

Jiang Yuan felt a little refreshed.

He is a big man, so it is not very convenient to get out of the car and get in. The narrow parking space makes him feel all kinds of inconvenience.

However, even in the county, there are very few parking spaces that are spacious enough to open the door at will. Unless you go to a certain ancient town outside the city, the shortage of parking spaces in the city began as early as ten years ago.

The newly acquired parking space is different. There is a flower bed on the left, and there is an acute angle cutting it in, which just gives the C16 parking space dozens of centimeters more space.

Jiang Yuan observed carefully that one-third of the parking spaces in Area C were corner parking spaces like this, which was quite convenient.

Even if the social IQ of some government officials is worrying, they would not waste so much area unconsciously - such wasteful behavior can only be done consciously.

Jiang Yuan looked around and felt that the flower bed wasted more area. In addition, the monitoring of the parking lot cannot achieve full coverage. In terms of the attributes of the unit... these must have been thought up by the dinosaur cerebellum of the administrative staff.

It's indeed a lot closer from the parking lot to the brigade's office building.

Along the way, everyone showed friendly smiles to Jiang Yuan.

Jiang Yuan is tall and big, and his police title has a gray label, so he can be recognized from afar.

Jiang Yuan also likes the atmosphere of this police station. Everyone is friendly and kind, like wild relatives he met when he went home for the New Year.

"Be honest!" Wu Junhao's voice penetrated into Jiang Yuan's ears.

Turning around, he saw Wu Junhao pushing a criminal suspect towards the interrogation center. His movements on the way were a little rough.

The cuffed criminal suspect was a douchebag, and said with a smile: "Don't be angry, I just said that I really just touched someone, it won't, it won't..."

"Don't be so playful, you're bleeding so much, why just touch it once?" Wu Junhao's voice became louder, and the flesh on his face bulged.

Wu Junhao was roaring with all his heart when he turned around and saw Jiang Yuan coming in.

"Hey, forensic doctor Jiang is back?" Wu Junhao couldn't help but smile.

If he could do murder cases, he wouldn't bother to do small security cases like this.

The dour-faced criminal suspect looked at Wu Junhao, who quickly changed his face, and whispered: "Who is smiling so playfully..."

"Do you want to die?" Wu Junhao's face suddenly appeared between his eyes.

The face as big as his butt made the suspect tremble in fright.

Jiang Yuan replied to Wu Junhao, said hello, and went upstairs.

Master Wu Jun had already prepared the Xuande stove and red eggs.

Jiang Yuan performed the traditional Ningtai forensic ritual smoothly. When the stove cooled down a little, he kicked it under the desk, peeled the eggs, and asked, "Is there a lot of work in our county?"

"A little bit, not much. We did a few injury assessments, and one person died in a car accident." Wu Jun said, and he also took a red egg to eat.

"Thank you for your hard work." Jiang Yuan said quickly.

The work in the county was originally done by two people. When he left for Qinghe City, Wu Jun had to do all the daily work. Although this is not the first time...but precisely because it is not the first time, I have to thank Wu Jun very much.

"There are only reports left, let me write them for you." Seeing Jiang Yuan's correct attitude, Wu Jun decided to give him a sense of participation.

Jiang Yuan then turned on the computer and began to write a report.

The report was a little annoying, but thinking that Mu Zhiyang had to write ten times as many reports made him feel much happier.

After roughly handling the remaining work in the county, Jiang Yuan was almost free by the afternoon.

He had nothing else to do, so he simply went to the video office next door and copied some videos to look at.

The three treasures of modern criminal investigation are images, mobile phones and DNA.

Especially for ordinary cases on the market, in many cases, it is indeed relatively simple to detect them through images.

Jiang Yuan also took this time to review the various camera positions he had seen during the day.

After watching the simple video for a while, Jiang Yuan felt like he was playing a silent movie, and he slightly lost interest.

I simply opened the intranet and found out the new cases that had been reported in the past few weeks.

For a county bureau, there will always be many cases that cannot be solved throughout the year.

Considering that many cases are blocked for various reasons before they are filed, the proportion of cases that are actually solved is indeed not high.

But from another perspective, the cases that have been filed still have certain detection value.

Jiang Yuan thought and immediately placed the scope of the case around Jiangcun Community.

Anyway, he has no leader to take care of him now.

And when the criminal police team is handling a case, there is no need to explain so much to others.

Just do it.

In recent weeks, there have been several cases around Jiangcun Community, but the nature of the cases are all minor, basically thefts and mixed fights.

Jiangcun community is still a bit too urban fringe. Many outsiders will pass through Jiangcun when they come to Ningtai County. Occasionally committing a crime is normal.

Jiang Yuan chose a theft case of cutting off bags and stealing mobile phones, and started reading.

In fact, it is not easy to solve the theft case.

First of all, most thefts are committed randomly.

This alone actually discourages many criminal investigation methods.

Veteran detectives have an advantage in this regard. This is because the suspects in theft cases are often bad guys in the same circle, with strong geographical location and dense network of connections. After asking, you can easily get the answer.

But if you don’t use informants and connections, solving a theft case may be even more difficult than solving a robbery case. Because the little thieves are more familiar with the blind spots of the camera, even if the remaining guys are stupid, they are still learning a little bit, hard, and seriously.

For Jiang Yuan, this level of difficulty was just right.

He just wanted to test his understanding of the monitoring system.

In addition, Jiang Yuan also has a killer move.

He already recognized the appearance of several thieves who often committed theft in Ningtai County. Although it was difficult to see faces clearly due to the quality of surveillance in Ningtai County, after getting familiar with several videos, Jiang Yuan was able to recognize the gaits of several people.

Gait recognition is already a very mature technology in China. At airports and high-speed rail stations, the first phase of surveillance AI investment uses gait recognition technology. In theory, thousands of people can be identified at a time.

On the contrary, the face recognition mode is more human-like and requires the construction of a special bayonet for recognition. And it can only be compared one by one.

Naturally, Ningtai County has no need for such monitoring AI. In fact, similar gait recognition systems are installed at airports and high-speed rail stations, and they are not used to catch small thieves.

A smart young man like Jiang Yuan is not that valuable. Within the time and place claimed by the reporter, Jiang Yuan quickly found a familiar gait.

If you follow up further, you will find that this person stayed at a bus stop three kilometers away from Jiangcun Community for a long time.

The place where he stayed was a surveillance blind spot, which meant that he also knew the location of the camera at the bus stop.

For ordinary detective police, this is more troublesome.

If you want to arrest someone, you have to fix the evidence. It is best to ambush at the bus stop in advance, or place a camera to collect evidence.

However, in Ningtai County now, there are too many people and few thieves. The thieves can't get past a bus stop every day. Two or three policemen are sent out, and they are half exhausted. They may have to squat for a month or two before they can get evidence. , this human cost is too high.

If it is not the mobile phone of a foreign friend or important person, no detective team will find it like this.

In addition, a lost mobile phone does not necessarily mean that it has been stolen. This is also the reason why many people report a crime after losing their mobile phone, but cannot file a case. The case that Jiang Yuan found was filed because the victim's bag had been cut open.

This confirms that the phone was stolen rather than lost.

Jiang Yuan then looked for other cameras.

Jiang Yuan has now determined that this man is stealing, and the question becomes: how to see the scene of him stealing.

Soon, Jiang Yuan found a farther camera.

Needless to say, image enhancement technology is developed.

At a certain point in time, pull out a few frames of images, apply some LV5 image enhancement, and you can perform all the actions of cutting bags and stealing mobile phones.

"Well... this is 13:32 noon on June 17th." Jiang Yuan wrote down the time and the surveillance number, took a photo with his mobile phone, and continued watching.

Facts have proved that the workload for a small thief is still very heavy.

This person is not motivated, he is still in the old style of stealing, but he has replaced stealing wallets with stealing mobile phones.

And it is still a two-person cooperation mode.

Jiang Yuan calculated a sentence of almost 10 years for him and then sent it to Wei Zhenguo.

After a while, Wei Zhenguo's call came over: "Good guy, didn't you just come back?"

"I just found it while playing surveillance..." Jiang Yuan and Wei Zhenguo chatted for a while and put down their mobile phones.

Downstairs, Wei Zhenguo had packed his bags and was ready to go arrest people.

Jiang Yuan hung up the phone and just when he was looking for another case, the ringtone rang again.

At a glance, it was Liu Jinghui.

Jiang Yuan sighed, why are there still thieves in Ningtai County? It's because everyone kills too many people.

If we could kill fewer people and commit fewer murders, freeing up the police's time, wouldn't these little thieves be caught quickly?

Jiang Yuan sighed and picked up the phone: "Liu Chu, is there a case?"

"The Wang Guoshan case here hasn't been completed yet." Liu Jinghui sighed and said, "This guy is a bit greasy. After he was sent to the detention center, he started bargaining with us."

"His ironclad death penalty is nothing to bargain for."

"It's always possible to ask for better food or something." Liu Jinghui's voice was a little tired as he said, "The key is that the interrogation didn't go well. Do you still remember the No. 3 remnant, that coal miner?"

"certainly."

"Yu Jun is the body that we have found dead the longest, but he is probably not the first person Wang Guoshan has killed. Moreover, Wang Guoshan is not willing to talk about the details of Yu Jun's killing. I am going to go to the scene to have a look."

"The scene where Yu Jun died?"

"Yes, Zifengshan Coal Mine. I'm going to take two dogs there to see if I can find anything."

Bringing the dog actually explained Liu Jinghui's thoughts. He was going to find the corpse.

Jiang Yuan couldn't help but think of the last Tan Yong case, where a group of dogs found the body in the ventilation shaft of the mine.

"Captain Shen agreed?" Previously, when Liu Jinghui wanted to take the dog to the coal mine, detachment leader Shen Feihong said no.

Liu Jinghui said nonchalantly: "I have no objection. I can just train the dog elsewhere."

"Then I'll go there tomorrow?"

"Forget it, just stay there. You can't do anything until the body is found, and you won't offend Shen Feihong." Liu Jinghui said a few more words before hanging up the phone.
