Chapter 202

Park.

Turn off the engine.

Push the door and get out of the car; the car door can be opened to the maximum without hitting the body of the car next to it.

Jiang Yuan feels a bit refreshed.

He is tall and big, so getting in and out of the car is not very convenient to begin with, and a narrow parking space makes him feel all kinds of inconvenience.

However, even in the county town, parking spaces spacious enough to open the car door at will are extremely rare. Unless you go to some ancient town outside the city, otherwise, the tension of parking spaces in the city started ten years ago.

The newly obtained parking space is different; to his left is a flower bed, and there is an acute angle cutting over, which just happens to give the C16 parking space a few dozen centimeters of extra space.

Jiang Yuan observed carefully; one-third of the parking spaces in the entire Area C are such corner parking spaces, which is quite convenient.

Even if the social intelligence of some government cadres is worrying, it wouldn't reach the point of unconsciously wasting so much area—such wasteful behavior naturally can only be conscious.

Jiang Yuan looked around and felt that the flower bed wasted more area. In addition, the surveillance of the parking lot cannot achieve full coverage; in terms of the unit's attributes... these must also be things thought up by the dinosaur cerebellum of the administrative staff.

From the parking lot to the brigade's office building, it is indeed much closer.

Along the way, everyone showed Jiang Yuan a kind smile.

Jiang Yuan is tall and big, and the police rank he wears is a gray badge, so he can be recognized from far away.

Jiang Yuan also likes this kind of police station atmosphere; everyone is kind and friendly, like meeting wild relatives when going home for the New Year. Whether he can call out their names or not, the smiles are really enthusiastic.

"Behave yourself!" Wu Junhao's voice was introduced into Jiang Yuan's ears with great penetrating power.

Turning his head to look, he saw Wu Junhao pushing a criminal suspect toward the interrogation center, his movements on the road looking slightly rude.

The handcuffed criminal suspect was a thick-skinned person, still smiling and saying, "Don't be angry, I'm just saying, I really just touched someone, it's not that serious, it's not that serious..."

"Don't be cheeky; so much blood flowed, and you just touched him?" Wu Junhao's voice grew louder, and the horizontal flesh on his face also bulged.

Wu Junhao was roaring to his heart's content when he turned his head and saw Jiang Yuan coming in.

"Oh, Wu Wu Fa Yi Jiang is back?" Wu Junhao couldn't help but release a smile.

If he could do homicide cases, he wouldn't bother doing these small public security cases.

The thick-skinned criminal suspect looked at Wu Junhao, who was changing his face rapidly, and said in a low voice, "Who is being cheeky..."

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

A face as big as a butt scared the suspect into trembling.

Jiang Yuan replied to Wu Junhao, greeted him, and went upstairs.

Master Wu Jun had long prepared the Xuande furnace and red eggs.

Jiang Yuan performed the Ningtai forensic traditional ceremony very smoothly. After the furnace cooled down a bit, he kicked it under the desk with his foot, then peeled the egg and asked, "Is there a lot of work in our county?"

"A bit, not much. Did a few injury appraisals, and there was a car accident death." Wu Jun said, taking a red egg for himself to eat.

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

The work in the county was originally done by two people. He went to Qinghe City, so all the daily work had to be covered by Wu Jun. Although it's not the first time... but precisely because it's not the first time, he must be especially grateful to Wu Jun.

"The reports are left; I'll let you write them." Wu Jun saw Jiang Yuan's upright attitude and decided to give him some sense of participation.

Jiang Yuan then opened the computer and started writing the report with a huff and a puff.

The report is a bit annoying, but thinking that Mu Zhiyang has to write ten times as much, his mood became much more pleasant.

After roughly dealing with the work left in the county, by the afternoon, Jiang Yuan was almost free.

He had nothing else to do, so he simply went to the image office next door and copied some images to watch.

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

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

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

After watching pure images for a while, Jiang Yuan felt as if he were watching a silent film, and he lost interest slightly.

He simply opened the intranet and found the new cases that had occurred in the last few weeks to watch.

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

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

But from another perspective, cases that have been filed still have a certain value for solving.

Jiang Yuan's mind turned, and he directly placed the scope of the cases around the Jiang Village residential area.

Anyway, he has no leaders managing him now.

And when the criminal police brigade handles cases, why would they need to explain so much to others?

Just do it.

In the last few weeks, there have been several cases around the Jiang Village residential area, but the nature of the cases is very light, basically theft and mixed fighting.

The Jiang Village residential area is still a bit too much on the edge of the city. When outsiders come to Ningtai County, many will pass through Jiang Village. Occasionally committing a case is truly normal.

Jiang Yuan chose a theft case of cutting a bag to steal a mobile phone and started watching.

In fact, the difficulty of solving theft cases is not low.

First of all, most theft cases are random crimes.

Just this one point actually discourages many criminal investigation methods.

Old criminal police officers have an advantage in this regard. It is because the suspects in theft cases are often bad people in the same circle, with strong regionality and dense relationship networks; asking around, it is easy to get an answer.

But if you don't use informants or relationship network methods, solving theft cases might be even harder than solving robbery cases. Because petty thieves are more familiar with the blind spots of cameras, even if the remaining few guys are stupid, they are finally learning bit by bit, diligently and seriously.

And for Jiang Yuan, this difficulty is just right.

He just wants to try his understanding of the surveillance system.

In addition, Jiang Yuan also has a big killer move.

He can already recognize the appearance of several petty thieves who often commit theft in Ningtai County. Although with the surveillance quality of Ningtai County, it is relatively difficult to see the face clearly, but after being familiar with several videos, Jiang Yuan has been able to recognize the gait of several people.

Gait recognition is already a very mature technology in China at present. The surveillance AI invested in the first phase of airports and high-speed railway stations adopts gait recognition technology. Theoretically, it can identify thousands of people at once.

Instead, the face recognition mode is more humanized and requires the construction of special checkpoints for identification. And it can only be compared one by one.

Ningtai County naturally cannot use such surveillance AI. In fact, even airports and high-speed railway stations that have installed similar gait recognition systems are not used to catch petty thieves.

A smart youth like Jiang Yuan is not so precious. Within the time and location range claimed by the reporter, Jiang Yuan quickly found a familiar gait.

Following the tracking, he found that this person stayed at a bus station three kilometers away from the Jiang Village residential area for a long time.

The place where he stayed is a surveillance blind spot, which shows that he also knows the location of the bus station's camera.

For ordinary image investigation police, this is relatively troublesome.

If you want to catch people, you have to fix the evidence, preferably ambushing at the bus station in advance or placing cameras to collect evidence.

However, in the current Ningtai County, there are many people and few thieves; petty thieves can't even run through a bus station in a day. Two or three police officers dispatched, tired to death, might have to squat for one or two months before it is possible to squat to evidence; the human cost of this is too high.

It's not the mobile phone of a foreign friend or an important person; no image investigation team will look for it like this.

In addition, losing a mobile phone is not necessarily stolen by someone; this is also the reason why many people lose their mobile phones and go to report the case, but it cannot be filed. And the case Jiang Yuan found, the reason why it was filed, is also because the victim's bag was cut open.

This confirms that the mobile phone was stolen, not lost by himself.

Jiang Yuan then looked for other cameras.

Jiang Yuan has now confirmed that this gentleman is committing theft, so the problem is transformed into: how to see the picture of him committing theft.

Soon, Jiang Yuan found a camera further away.

Needless to say, get the image enhancement technology going.

At the determined time point, pull out a few frames of images, and with a bit of LV5 image enhancement, the actions of cutting the bag and stealing the mobile phone are all there.

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

Facts have proved that when petty thieves work, the workload is still very large.

This person is also not enterprising, still in the old-fashioned mode of cutting bags to steal, just changing from stealing wallets in the past to stealing mobile phones now.

And it is still a mode of two people cooperating.

Jiang Yuan calculated and added up a prison sentence of about 10 years for him, and then sent it to Wei Zhengguo.

In a while, Wei Zhengguo's call came: "Good guy, didn't you just come back?"

"I found it while playing with surveillance..." Jiang Yuan chatted with Wei Zhengguo for a few words and put down his mobile phone.

Downstairs, Wei Zhengguo had already packed his gear, ready to set off to catch people.

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

Taking a look, it's Liu Jinghui.

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

If everyone could kill a little less, have a little fewer homicide cases, and let the police free up time, wouldn't these petty thieves be caught clean very soon?

Jiang Yuan sighed and answered the phone: "Director Liu, is there a case?"

"The Wang Guoshan case here hasn't been finished yet." Liu Jinghui sighed and said: "This guy is a bit oily; after being sent to the detention center, he started bargaining with us."

"He is definitely getting the death penalty; what is there to bargain about?"

"Demanding to improve food or something, it's always possible." Liu Jinghui's voice was a bit tired, saying: "The key is that the interrogation is not going well. Number three, Yu Jun, that coal miner, you remember, right?"

"Of course."

"Yu Jun is the body we found that has been dead the longest, but it shouldn't be the first person Wang Guoshan killed. Moreover, Wang Guoshan is not very willing to talk about the details of killing Yu Jun. I plan to go to the scene to see."

"The scene where Yu Jun died?"

"Yes, Zifeng Mountain Coal Mine. I plan to take two dogs there to see if I can find anything."

Taking dogs actually already explains Liu Jinghui's thoughts; this is going to find a body.

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

"Did Captain Shen agree?" Previously, Liu Jinghui wanted to take dogs to the coal mine, but Detachment Captain Shen Feihong denied it.

Liu Jinghui said indifferently: "Didn't oppose. I'll just borrow dogs from elsewhere."

"Then I'll go over tomorrow?"

"Forget it, you stay there. Before finding the body, you can't do anything, and it avoids offending Shen Feihong." Liu Jinghui said a few more words and hung up the phone.
