Chapter 918 The Bell Rings

"I heard that there is a case that cannot be advanced?" Huang Qiangmin heard that Liu Jinghui was coming and rushed over immediately.

"The source of corpse No. 2 last time, the female corpse, has never been determined." Jiang Yuan stood up from behind the computer, stretched his back, and said: "This case is more troublesome. The corruption of the corpse was not very serious. Seriously, after drawing it, the face cannot be recognized, so cranial reconstruction is useless. "

Jiang Yuan dared to start a Taihe working group. Skull reconstruction is a big killer. In theory, as long as the skull is still on the corpse, Jiang Yuan can get the approximate face of the deceased through cranial reconstruction. In addition, with the current facial recognition technology in China With the widespread application of technology, the difficulty of determining the source of a corpse may be only one percent that of an ordinary police station.

LV6's forensic sketching is another enhancement to the skull restoration technique. The skull restoration technique is more universal, as long as the head is present, it doesn't matter if it is rotten or not, it is more convenient to rot into bones. The advantage of forensic sketching is that it is fast. It does not need to be a week-long work like cranial reconstruction. With just a few strokes, ten minutes, or at most an hour, a drawing can be produced, and the drawing is very accurate. It is also higher than cranial reconstruction surgery, and has a higher success rate when applied to facial recognition.

However, as soon as the Taihe working group started, one corpse with an unrecognizable face appeared among the three corpses, which more or less surprised Jiang Yuan.

In contrast, Huang Qiangmin felt that it was normal and said with a smile: "It is too common that facial recognition is not possible. If you use the drawn picture as a photo, the computer will definitely not recognize it."

Jiang Yuan has had forensic sketch LV6 for a while, but he hasn't used it much, and Huang Qiangmin doesn't know much about it either.

Jiang Yuan shook his head clearly and said: "I have perfected my forensic sketch, which is similar to the level of footprint identification, and will not be unrecognizable."

While talking, Jiang Yuan took a digital tablet and drew a few strokes to draw Huang Qiangmin's current appearance. It was not vivid at all, just like an ID card photo, but the nose, eyes and ears were complete, and the human body features were intact. Neatly looking.

Huang Qiangmin was speechless for a while, then became serious again.

He has been a criminal policeman for 30 years, and he has read countless ID cards. Once he takes a look at it, he knows where to look and what characteristics he is looking for.

The same type includes criminal photos. Photographers who specialize in taking pictures of prisoners and dead people. In the era before digital cameras, it took special practice to perfectly reflect the facial features in every photo. As for whether they look good or not, before ID cards were not allowed to beautify their photos, some of them were really good-looking.

The Huang Qiangmin drawn by Jiang Yuan is certainly not good-looking, but Huang Qiangmin is also really ugly. But no matter what, there is absolutely nothing wrong with taking out this photo and posting it on the wanted poster.

In other words, Jiang Yuan's sketching skills are really good.

Like Liu Jinghui, Huang Qiangmin quickly updated his understanding of Jiang Yuan's skills, and his brows gradually furrowed: "You haven't been swept out yet?"

Jiang Yuan then reported his and Liu Jinghui's analysis and decision. Huang Qiangmin is now the political commissar of the bureau. Although he still holds the position of captain of the criminal police brigade, he has very little interference in criminal cases. On the surface, each squadron is allowed to exert its independent combat capabilities. In fact, it is delegating power to the greatest extent. To Jiang Yuan.

Otherwise, if the Ningtai County Bureau appoints another criminal police captain, he will have to work with Jiang Yuan. The key is that Jiang Yuan may not be willing to get along with newcomers, and it is not easy for a small county bureau to support such a great figure as Jiang Yuan. At least after Director Chai left, the top management has become more Buddhist.

"I basically agree with your judgment. Are there enough people to visit? Do you need support from other squadrons?" This is also the main reason why Huang Qiangmin came to understand the situation.

"With the help of the first squadron of the team, it is still possible for now." Jiang Yuan replied.

Huang Qiangmin nodded and said: "I will reorganize the staff. This kind of visit can be easily expanded."

In fact, it will expand. If the early stage of the visit goes smoothly, the case will be solved. But if the early stage does not go well, if no suspect or evidence is found in the place where the suspect or evidence is most likely to be found, the scope of the visit can only be extended. . This part can be understood as drawing a circle. As the radius increases, the area of ​​the circle increases exponentially.

Jiang Yuan nodded, a little annoyed.

After all, he is still a technician, and even the epaulettes he wears are gray epaulettes used by professional technical police. This is what he is good at. As for visiting, it is actually a traditional art skill of criminal policemen. It is said that the strength of the soles of the feet is used to prove the ability to solve crimes.

"If there is no breakthrough in the short term, we may have to deploy two squadrons." Jiang Yuan paused and said, "I should have nothing to do these two days. If there is no result in this drowning case, I can help other squadrons first. Handle the case. Which squadron needs it?"

Except for the newly-built Taihe Working Group, there are no heavyweight cases in Ningtai. It is a bit exaggerated to say that the house is open at night, but except for sudden cases and crimes of passion, high-quality premeditated crimes and professional criminals can be said to be rare. .

Under this situation, several criminal police teams are pursuing cases. The backlog of murder cases has been cleared by Jiang Yuan to 30 years ago. However, for the other seven of the eight major serious cases, there are still many backlogs left, some of which involve serious injuries. Rape, arson, and explosion are still very serious cases, and they are worthy of tracing, but they are also more difficult to do.

Because Jiang Yuan was responsible for resource support, he had been working on big cases in other places before. When he came back occasionally, he couldn't just pick peaches. This time is the same. I believe there is always a squadron that is chasing the previous case and is angry, and has technical needs to find Jiang Yuan.

My dear, there is more to this chapter. Please click on the next page to continue reading. The latter is more exciting!

Sure enough, Liu Wenkai came to the door in a short while.

"I heard that you change the clock here?" Liu Wenkai brought two people, notebooks and files, and came over with a smile.

"What?" Jiang Yuan didn't understand.

"What Huang Zhengwei meant is that you don't have to pay for your clock, and you can pay more clocks according to the time." Liu Wenkai said seriously, and then said: "It is said that this is not illegal."

"Did I say that?" Huang Qiangmin walked in.

Liu Wenkai hurriedly said: "The part about not being illegal is my blind guess!"

Huang Qiangmin: "Isn't it the key that it is not illegal?"

"Isn't it the key that it is not illegal?" Liu Wenkai asked back.

Huang Qiangmin gave up: "Let's talk about the case."

"Oh, we have a robbery case here. The case happened 12 years ago. The suspect took advantage of the closing time of a fruit supermarket and robbed the owner. He took away more than 7,000 yuan in sales revenue and many expensive cigarettes and fled on a bicycle. The owner reported the case, and the police conducted a relatively detailed investigation..." Liu Wenkai came in a hurry, so he put photos while introducing the case, and soon filled the table.

The police of Ningtai County Bureau are actually very skilled in how to use Jiang Yuan, mainly because they can't get a clock.

Liu Wenkai knew that he could use Jiang Yuan for two days, so he naturally brought all the equipment he could bring.

Jiang Yuan looked at the photos one by one.

The drowning case was still during the visit, and he had no idea for the time being. As for the robbery case in front of him, the previous generation of the special task force investigated it seriously, but the criminals were also very serious in their preparations. From a few surveillance photos, it can be seen that the criminals wore hats, sunglasses, masks, scarves and gloves, and did not show anything on their bodies.

The investigators also speculated that the suspect had tattoos and investigated a large number of people with criminal records.

Jiang Yuan pondered and thought. From his point of view, there was nothing wrong with the thinking of the previous generation of investigators. The criminals performed very professionally in the robbery. Not only were they fully equipped and had a clear escape route, but the robbery was also neat and tidy. Holding a baton and a knife, they smashed the counter of the fruit supermarket in two snaps, took cigarettes for themselves, and threatened the owner to take money.

The whole process cannot be said to be smooth, but there is definitely criminal experience. This lesson is very practical, and you can't practice it in advance.

"How about it, do you have any ideas? Do you need us to cooperate with anything?" Liu Wenkai was quite active. Although he is his own technician, Huang Qiangmin said that he must return the clock, so Liu Wenkai naturally didn't want to waste a bit.

Jiang Yuan thought for a while and said, "We can only try one by one. From the ideas you have done, I think we can start from the tool marks."

Now he chooses the investigation plan, and often chooses from his own technical library. Of course, technicians all have this idea. When facing the same problem, those who are good at Java use Java, those who are good at C use C, and those who are good at shifting the blame prepare the blame in advance. It's the same principle.

Jiang Yuan then followed the idea of ​​tool marks and directly drew the appearance of the baton and knife used by the suspect based on the traces left at the scene.

After the picture came out, he went to the tool mark database to search.

After searching like this, many tools or photos of tools involved in the case appeared on the page.

Jiang Yuan compared them one by one, but he didn't flip through many of them, and found that the front end of the baton in a picture was slightly special.

When he returned, he saw that this was a case of fighting that had been solved. The two sides of the fight, one used a baton, the other used a chair, so each of them was beaten with 80 lashes...

"Catch these two people and ask them." Jiang Yuan retrieved the information of one party in the fight, looked at the height, age and other information, and was more certain.

Liu Wenkai then got two printed papers, and then looked at the time, and was a little surprised: "It came out so quickly?"

"Lucky, the first method I tried produced results." Jiang Yuan said, waving to Wang Chuanxing, saying: "I remember that the drowned victim had multiple pre-mortem injuries, which should be caused by violent beatings."

"Can you find the tools based on this?" Wang Chuanxing was listening nearby, and he immediately drew inferences from one example.

Jiang Yuan shook his head: "It should be beaten with hands, but after being beaten, she might go to buy some anti-inflammatory drugs, painkillers and the like. She may not necessarily go to a large hospital, and a small clinic nearby is also possible."

"Women who have been beaten within a month should have a deep impression on the clinic staff." Liu Jinghui was thinking with his head covered, and now he sat up suddenly.
