National Forensic Doctor

Director Tan Jingtan also accompanied him to read the files and eucalyptus, but he read them very casually.

Not to mention that he has handled all the cases before, but it is not that easy to break the case. If he could detect it with a wave of his hand, he wouldn't put it here.

As for why these eucalyptus cannot be broken, it can be said that the difficulty is part of it, and the lack of resources is also part of it. But these two items are actually unsolvable. At least so far, Director Tan and his Zoumadao Police Station have not fundamentally changed in these two aspects.

Therefore, Director Tan looked more at Jiang Yuan.

It's like being a scumbag watching a top student do his homework. There is no point in doing it yourself. It is better to wait for the top student to finish writing and start copying it directly.

"Tan Suo, would you like to pick two eucalyptus seeds?" Jiang Yuan looked at several eucalyptus seeds and felt there was no difference, so he asked the landlord directly.

I can't see it in some eucalyptus files, maybe Tan Jing has an idea.

Jiang Yuan asked, and Tan Jing couldn't help but cheer up, thought for a while, and said: "It's better to do this 403 oil stealing first, so that we can collect more evidence."

Wang Chuanxing was nearby and quickly found the corresponding file, and then called up more photos and videos on the computer.

Jiang Yuan read them one by one, and the others also read the files and checked the reports.

For a while, seeing that Jiang Yuan remained silent, the others began to discuss among themselves.

People like Pang Jidong are also the ones who make trouble in Luojin City every day. The criminal policemen under his brigade were able to do three or four tasks in parallel, such as stealing oil, without any problem.

Sitting in the conference room of the police station now, several people saw that Jiang Yuan remained silent, so they simply went their own way.

Not long after, Pang Jidong directly sorted out several inquiry transcripts and said, "I noticed that there seemed to be several names in them that appeared frequently. I excerpted a few..."

Everyone looked over and saw on the paper: "Fei Zi told me", "Dunzi came to look for me", "I met Fei Zi"...

The transcript contained a lot of very colloquial content. A police officer from the police station read it over and said, "This guy is a criminal with a criminal record. He has a criminal record of stealing diesel. I caught him once..."

Pang Jidong nodded and said: "He often appears in the mouths of various criminals. He must be an activist and can be focused on."

Tan Suo then stood up and went to Pang Jidong, looked at the materials he had compiled, and said: "Looking at it this way, this person is indeed likely to commit suicide. Then bring him back and ask?"

"I suggest you follow him for a while and then take action if you can find evidence." Pang Jidong looked a little cautious.

Tan Suo was in a bit of a dilemma, but there was no problem in keeping watch. They did very little in tracking.

Today's police officers spend half of their time at their desks. The area under the jurisdiction of Zoumatao is relatively large and it is a suburban office. Most of the investigations are handed over to the criminal police team, and they do not Very good at detecting cases.

"Captain Jiang, what do you think?" Tan Jing looked at Jiang Yuan. He was still more willing to listen to Jiang Yuan. Although the police rank on Pang Jidong's shoulders is high, he cannot control the police stations in neighboring provinces.

Jiang Yuan woke up from his dream. After thinking for a moment, he knew what Tan Jing was in trouble for, and said, "Team Liu will take over the tracking job?"

"It works." Liu Wenkai agreed for Jiang Yuan's sake.

Tan Jing couldn't help but breathe a sigh of relief.

Tracking and squatting is not an easy job. It is a hard and tiring type. Imagine a girl renting a room with someone else. We don’t know whether the girl is tired and wants to sleep with someone, or she wants to sleep with someone. We can’t rush in and be incompetent. Furious, but unable to turn around and leave, he squatted in his car and stood guard under the hotel, looking at the entrance and exit from time to time, hoping to catch the two of them coming out.

This time may be 20 minutes, or it may be a day and night. During the waiting time, it is neither convenient to leave nor anywhere to move your body. It will only become more and more tired and uncomfortable...

It would be best if Liu Wenkai was willing to agree. At least, Tan Jing felt that he could not invite him.

"I'll study the evidence again, you guys make the eucalyptus first." Jiang Yuan got some inspiration while looking at the eucalyptus, and simply gave up the job.

Tan Suo agreed without knowing why.

After leaving the door, Tan Suocai hesitantly asked Wang Chuanxing next to him: "Is Captain Jiang a little unhappy?"

"No, Captain Jiang probably had something in mind and wanted to make a big splash." Wang Chuanxing said naturally.

Pang Jidong also said: "It was the same when we were in Luo Jin. Team Jiang looked at plants and pollen for a long time before taking action..."

"Oh, that's good." Tan Suo agreed, but he was still a little uneasy in his heart. If it was a single incident, he felt that there might be nothing wrong with Jiang Yuan's behavior, but in a series of incidents, could there be something in common? Can't? It’s not done by one person or a group of people.

Looking back, more than 20 members of Jiangyuan's special squad have joined. Liu Wenkai from the Second Squadron has joined with more than a dozen people. The Zoumadao Police Station is unprecedentedly strong, Tan Jing thought in private, embarrassedly. , in this way, it seems that Jiang Yuan is not needed to join.

In other words, even if Jiang Yuan joins, the situation may not be better.

The combat power of the Zoumadao Police Station seems to have reached its maximum today.

On that day, Liu Wenkai sent four people and two cars, carrying eight bottles of Pulse, to the residences of "Feizi" and "Dunzi" for surveillance.

In addition, four vehicles from Jiangyuan Jiyu Special Squad, plus two other vehicles from the Second Squadron, and four vehicles from the Zoumadao Police Station went to three service areas around Ningtai at night to investigate.

Truck drivers were stolen mainly in the service area. Among them, oil theft is the most important, there are also tire thieves, and there are also people who transport stolen goods. However, the difficulty of these three things increases. The more subsequent incidents, the more the public security deteriorates.

Pang Jidong and the policemen from Luojin City Bureau who came with them were taken care of and did not need to work the night shift. They could just wave goodbye.

Watching a group of twelve cars leave, the policeman who came with him suddenly said: "Pang Pang, did you notice the license plate?"

"Yeah." How could Pang Jidong not notice that among the 12 cars, none of the license plates started with "山L", and there were only a few cars with "山O", and several of them were from other provinces. The license plate is simply outrageous.

Pang Jidong thought with his sinuses and knew that these were neither vehicles with license plates from Qinghe City, Shannan Province, nor police license plates. Most of them were "robbed" by Huang Qiangmin.

"Our detachment doesn't have as many cars as their county bureau." The policeman who came with him sighed with emotion.

Pang Jidong chuckled, looked at him, and said: "Cars are just personal belongings. Last time we did DNA for the university, we could buy a Porsche with the money. I'm afraid that Lao Huang will collect too many cars and start asking for people." That’s troublesome.”

The policeman who came with him laughed: "You can't buy and sell people."

Pang Jidong pointed at him and then at himself.

The wind in Ningtai suddenly became chilly.

…

In the police station, Jiang Yuan was still looking through the photos, and he was just looking through the photos and taking notes from time to time.

The policemen nearby didn't understand why, and Jiang Yuan couldn't explain it either.

He was actually looking for tool marks.

Diesel from large vehicles is particularly easy to steal because the fuel tanks of large vehicles are basically completely exposed. Moreover, the fuel tank port is a standard port. Oil thieves can poke a high-power oil pump into it and steal all the oil in a few minutes. They can stuff it into the tank as soon as they wear clothes.

However, there are requirements for the step of poking the oil pump in. Nowadays, most large vehicle fuel tanks have locks, and some even lock them tightly.

Some oil thieves who are new to the industry are also troubled by the lock.

Under normal circumstances, you just use a knife to pry it open, which is about as difficult as opening an oyster. Those who are more prepared may also use a crowbar. There are heretics who use Swiss Army knives, and the most powerful ones actually use lock picking tools, which reflects another expression of industry involution.

But no matter what tool is used, the traces left behind are distinctive.

The most important thing is that all cases where large trucks are stolen involve tool issues. Not only do you need to pick the lock, but you also need to use the oil pipe and oil pump.

The latter two will not leave any traces on the truck, but the oil pipe after pumping the oil cannot be smooth and dirt-free. The diesel oil dipped outside the pipe will drip to the ground, forming certain traces. .

Some pipes will also leave traces of towing - a tank that steals oil may not necessarily park next to the stolen vehicle, but may park in the middle of the road, then pull a ten-meter-long pipe and park it secretly The oil coming down from the cart.

And based on the moral integrity of oil thieves, when collecting the pipe, there is a high probability that they will not clean the pipe and then carry it back properly. The most common thing is to drag it on the ground for a while and then put it away in the most labor-saving way.

These are all tool marks.

In addition, oil tanks can easily leave corresponding traces. For example, tire marks. Many times, there is soft ground where the cart stops, leaving clearer traces.

Since there are often one thing broken and another broken in the police station, the criminal police team does not have enough trace inspection skills to sort out these, so even if they know that there are traces, they will not deal with them specially.

But for Jiang Yuan, his goal is definitely not to make two eucalyptus dumplings at the same time, nor is it like taking a long time to make a batch of eucalyptus dumplings as Director Tan imagined.

At this time, Jiang Yuan can completely use LV6's tool mark identification to classify the traces of these pieces.

Although there are many oil thieves in nearby cities and counties, and there are gangs flowing back and forth from inside and outside the province, the real eaters are the three-digit people.

After all, stealing 600 liters of oil in one night is equivalent to an income of 3,000 yuan. If two people cooperate, it will be more than 1,000 yuan per person.

If these oil thieves want to make a living, they must operate very quickly.

Jiang Yuan classified the cases through tool mark identification. Not only did he classify multiple cases under the name of each numbered thief, he could even classify the cases that had been detected.

In other words, if an ex-convict commits another crime, he may be directly identified by Jiang Yuan through tool mark identification.

Even if the tools are changed, the operating habits remain unchanged, and there is still a basis for judgment.

Jiang Yuan didn't even activate the "temporary +1" skill, so LV6 was already too much.

The only thing that is more troublesome is that I have accumulated a lot of photos. In the first five years, there were so many photos that I couldn't finish them in two or three days.

But if the first day of the new year is too short, I am afraid that some thieves have not yet come out of prison.

Jiang Yuan silently worried about sending the ex-convicts back to prison, and then heard someone yelling downstairs.

Just because his eyes were tired from looking at it, Jiang Yuan simply got up and went out. He went to the corridor at the door and looked down.

The first floor of the Zoumadao Police Station is a high-ceiling hall, used to receive people who report crimes and other work.

Therefore, if you look down from the corridor on the second floor, you can see the top of the reporter's head.

At the moment, there is a white-haired old lady with a girl with a bun.

"Captain Jiang." The policeman in the next room was also watching the fun and said hello with a smile.

Jiang Yuan nodded and said with a smile: "You stay in the police station every day, why are you watching the excitement?"

"Today's one is a bit impressive." The policeman next door laughed: "The family of the person who called the police was doing live video broadcasting in their spare time. In less than a month, they had more than 1,000 fans. Then someone from a media company came to the door and claimed to be She could be trained to become an Internet celebrity, but she would need a training fee. The person who called the police would not let her send the money, so she made a fuss at home and finally called the police."

"This is a scam."

"It's almost the same, but it's hard to define. What the other company wants is training fees. The problem is that people believe it themselves and would rather lose money than give it a try."

Jiang Yuan nodded and said: "There are too many young people who want to be Internet celebrities now."

The policeman next door laughed out loud: "I guess you won't guess that the one who wants to be an Internet celebrity is this white-haired Granny Zhang."

Jiang Yuan was stunned for a moment, then looked down and saw that the scene became more vivid.
