parking.
Turn off the fire.
Push the door and get off the car, the door can be opened to the maximum without bumping into the car next door.
Jiang Yuan felt a little refreshed.
He is big, so it is not very convenient to get out of the car, and the narrow parking space makes him feel all kinds of inconvenience.
However, even in the county town, 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 started as early as ten years ago.
The new parking space is different. To his left is a flower bed, which is cut at an acute angle, which just leaves the C16 parking space tens of centimeters more.
Jiang Yuan observed carefully that one-third of the parking spaces in the entire C area were corner parking spaces like this, which was quite convenient.
Even if the social IQ of some government cadres is worrying, it is not enough to waste so much area unconsciously-such a wasteful behavior can only be conscious.
Jiang Yuan looked around and felt that the flower beds were wasting more area.In addition, the monitoring of the parking lot cannot achieve full coverage. As far as the attributes of the unit are concerned... these must have been thought up by the dinosaur cerebellum of the administrative staff.
From the parking lot to the office building of the brigade, it is indeed much closer.
Along the way, everyone showed cordial smiles to Jiang Yuan.
Jiang Yuanchang is tall and tall, and his police rank is gray, so he can be recognized from afar.
Jiang Yuan also likes the atmosphere of the police station, everyone is friendly, like wild relatives he met when he went home for the New Year, not to mention his name, the smile is really warm.
"Be honest!" Wu Junhao's voice penetrated into Jiang Yuan's ears.
Turning his head to look, he saw Wu Junhao was pushing a criminal suspect towards the interrogation center, his movements on the road were a little rough.
The criminal suspect who was handcuffed was a fool, and he said with a smile: "Don't be angry, I mean, I just touched someone, it's not, it's not..."
"Don't be joking, you've bled so much, just touch it?" Wu Junhao's voice became louder, and the flesh on his face bulged.
Wu Junhao was roaring with all his heart, and when he turned his head, he saw Jiang Yuan coming in.
"Hey, forensic doctor Jiang is back?" Wu Junhao couldn't help but let out a smile.
If he could do a murder case, he wouldn't be bothered doing such a small security case.
The two-faced criminal suspect looked at Wu Junhao, who quickly changed his face, and said in a low voice, "Who has a hippie smile..."
"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 ceremony of Ningtai forensic medicine very smoothly. When the stove cooled down, he kicked under the desk with his feet, then peeled the eggs, and asked, "Are there many jobs in our county?"
"A little bit, not much. I did a few injury appraisals, and one 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 hurriedly said.
The work in the county was originally done by two people. After he left Qinghe City, Wu Jun was responsible for all the daily work.Although it's not the first time... But it's because it's not the first time, so I have to give special thanks to Wu Jun.
"The report is left, let me write it 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 the report humming.
The report was a bit annoying, but thinking that Mu Zhiyang had to write a report ten times longer than this, the mood became much happier.
After roughly handling the remaining work in the county, Jiang Yuan was almost free in the afternoon.
He had nothing else to do, so he simply went to the video office next door and copied some videos to watch.
The three treasures of modern criminal investigation are video, mobile phone and DNA.
Especially for ordinary cases on the market, in many cases, it is indeed relatively simple to solve them through video.
Jiang Yuan also took advantage of 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 a silent movie, and lost interest a little.
Simply open the intranet and find out the new cases in recent weeks.
For a county bureau, there will always be many cases that cannot be solved throughout the year.
Considering that many cases were blocked for various reasons before the case was filed, the proportion of cases that were actually solved was indeed not high.
But from another point of view, the cases that have been filed still have a certain detection value.
Jiang Yuan changed his mind and directly put the scope of the case around the Jiangcun community.
Anyway, he has no leader to take care of him now.
And the criminal police team handles the case, why do they need to explain so much to others.
Just do it.
In recent weeks, there have been several cases around the Jiangcun community, but the nature of the cases is very light, basically theft and mixed fights.
The Jiangcun community is still a bit too out of the city. When foreigners come to Ningtai County, many of them will pass through Jiangcun.It is normal to commit a crime occasionally.
Jiang Yuan chose a theft case in which the mobile phone was stolen by cutting the bag, and started to watch it.
In fact, the difficulty of cracking the theft is not low.
First of all, most thefts are committed randomly.
This alone actually dissuaded many criminal investigation methods.
The old detectives have an advantage in this respect.It is because the suspects in theft cases are often bad people in the same circle, with strong regional characteristics and dense network of relationships. After asking, it is easy to get the answer.
But if you don't use informants and relationships, solving the theft case may be even more difficult than solving the robbery case.Because the thieves are more familiar with the blind spots of the camera, even if the remaining few guys are stupid, they are still learning a little bit, working hard, and earnestly.
For Jiang Yuan, the difficulty was just right.
He just wanted to test his understanding of the monitoring system.
In addition, Jiang Yuan has a big killer.
He already recognized the appearance of a few petty thieves who often carried out theft in Ningtai County.Although it is difficult to see the faces clearly with the quality of surveillance in Ningtai County, after familiarizing themselves with several videos, Jiang Yuan can already recognize the gait of several people.
Gait recognition is already a very mature technology in China at present.For airports and high-speed rail stations, the monitoring AI that was invested in the first phase uses gait recognition technology.In theory, thousands of people can be identified at a time.
On the contrary, the face recognition mode is more humanized and requires the construction of a special bayonet for recognition.And it can only be compared one by one.
Naturally, Ningtai County does not need such monitoring AI. In fact, even airports and high-speed rail stations have installed similar gait recognition systems, and they are not used to catch small thieves.
A wise young man like Jiang Yuan is not so precious. Within the time and place claimed by the informant, Jiang Yuan quickly found a familiar gait.
Follow up and follow up, and you can find that this person stayed for a long time at the bus station three kilometers away from the Jiangcun community.
The place where he stayed was a monitoring blind spot, which meant that he also knew the location of the camera at the bus stop.
For ordinary graphic investigation police, this place 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 many people and few thieves. The thieves can't run to a bus stop a day. Two or three policemen are dispatched, and they are exhausted. They may have to wait for a month or two before they can get evidence. , the human cost is too high.
It is not a mobile phone of a foreign friend or an important person. No graphic investigation team will look for it like this.
In addition, a lost mobile phone is not necessarily stolen by someone, which is why many people lose their mobile phones and report to the police, but the case cannot be filed.And the case Jiang Yuan found was filed because the victim's bag was cut open.
This confirms that the phone was stolen, not lost.
Jiang Yuan then looked for other cameras.
Now that Jiang Yuan has confirmed that this gentleman is stealing, the question becomes: how to see the picture of him stealing.
Soon, Jiang Yuan found a far camera.
Needless to say, image enhancement technology is up.
At a certain point in time, a few frames of images are pulled out, some LV5 image enhancements are added, and the actions of cutting packets and stealing mobile phones are all there.
"Well... this is 6:17 on June 13th." Jiang Yuan wrote down the time and the monitoring number, took a photo with his mobile phone, and continued to watch.
Facts have proved that when the thief works, the workload is still very large.
This guy is not motivated, and is still the old-fashioned way of cutting and stealing. He just changed from stealing wallets to stealing mobile phones now.
And it's still a two-person team.
Jiang Yuan calculated for him almost 10 years in prison, and then sent it to Wei Zhenguo.
After a while, Wei Zhenguo's call came: "Good guy, didn't you just come back?"
"I found out while playing surveillance..." Jiang Yuan chatted with Wei Zhenguo for a while, then put down the phone.
Downstairs, Wei Zhenguo had already packed his bags and was about to set out to arrest people.
Jiang Yuan hung up the phone, and when he was looking for the case again, the bell rang again.
Take a look, Liu Jinghui.
Jiang Yuan sighed, why there are still small thieves stealing in Ningtai County, it is because everyone kills too much.
If everyone can kill fewer people, reduce homicides, and free up the police, wouldn't these little thieves be caught soon?
Jiang Yuan sighed and picked up the phone: "Liu Chu, do you have a case?"
"The case of Wang Guoshan is not over yet." Liu Jinghui sighed, and said, "This guy is a bit oily. After being sent to the detention center, he started to bargain with us."
"He is determined to die, what is the bargain."
"It's always okay to ask for better food." Liu Jinghui said in a tired voice, "The key is that the interrogation didn't go well. The No. [-] Remnant Army, that coal miner, you remember."
"of course."
"Yu Jun is the longest dead body we found, but it probably wasn't the first person Wang Guoshan killed. Moreover, Wang Guoshan is not willing to reveal the details of Yu Jun's killing. I'm going to go to the scene to see."
"The scene where Yu Jun died?"
"Yes, Zifeng Mountain Coal Mine. I'm going to take two dogs there to see if I can find anything."
Bringing the dog already explained Liu Jinghui's thoughts, and he was going to find the corpse.
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.
"Captain Shen agrees?" Earlier, when Liu Jinghui wanted to take the dog to the coal mine, the detachment leader Shen Feihong denied it.
Liu Jinghui said indifferently: "I have no objection. I can transfer the dog from elsewhere."
"Then I'll go there tomorrow?"
"Forget it, just stay here, you can't do anything until you find the body, and you won't offend Shen Feihong." Liu Jinghui said a few more words before hanging up the phone.
