Chapter 898: The Bell Rings

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

"The second corpse last time, that female corpse, has never determined the source of the corpse." Jiang Yuan stood up from behind the computer, stretched his waist and back by the way, and added: "This case is more troublesome. The decay of the corpse was not very serious originally. It was drawn, but the facial recognition was not found. In this way, the skull restoration technique is useless."

Jiang Yuan dared to open the Taihe Working Group. The skull restoration technique is a big killer. Theoretically, as long as the skull is still there, Jiang Yuan can get the approximate face of the deceased before death through the skull restoration technique. Coupled with the wide application of facial recognition technology in the country, the difficulty of determining the source of the corpse may only be one percent of the ordinary police station.

The forensic sketch LV6 is a double reinforcement of the skull restoration technique. The skull restoration technique has stronger universality. The head is there, and it doesn't matter if it is rotten or not. It is more convenient to rot into white bones. The advantage of forensic sketching is fast. It doesn't take a week-long work like skull restoration. A few strokes, ten minutes, at most an hour, can produce a picture, and the accuracy of the picture is higher than that of skull restoration, and the success rate of application to facial recognition is even higher.

However, the Taihe Working Group just started, and a corpse that could not be facial recognized appeared among the three corpses, which still surprised Jiang Yuan a little.

In contrast, Huang Qiangmin felt normal and smiled. "Facial recognition is too common. You use the drawn picture as a photo, and the computer will definitely not recognize it."

Jiang Yuan's forensic sketch LV6 has been obtained for a while, but it has not been used much, and Huang Qiangmin does not know much about it.

Jiang Yuan shook his head clearly. "My forensic sketch has been practiced well, and it is about the same level as footprint identification. It will not reach the level of not being recognized."

While talking, Jiang Yuan took a digital board by the way, brushed a few strokes, and drew Huang Qiangmin's appearance at this time. It was not vivid, just the feeling of an ID photo, but the nose, eyes, and ears were all there, and the human characteristics were neat.

Huang Qiangmin looked speechless, and then it was a serious one.

He has been a criminal police officer for 30 years. He has seen ID cards countless times. Once he looks over, he knows where to look and what characteristics he wants.

The same type is criminal photos. Photographers who specialize in taking photos of prisoners and dead people, in the era without digital cameras, have to practice specifically to make every photo perfectly reflect the characteristics of the face. As for whether it looks good or not, before ID photos were allowed to be beautified, how many were really good-looking?

The Huang Qiangmin drawn by Jiang Yuan is certainly not good-looking, but he, Huang Qiangmin, is really not good-looking. But in any case, this photo is taken out and posted in the wanted order, absolutely no problem.

In other words, Jiang Yuan's sketch level is really capable.

Like Liu Jinghui, Huang Qiangmin quickly updated his understanding of Jiang Yuan's skills, and his brow gradually furrowed. "Even like this, it wasn't scanned?"

Jiang Yuan then reported the judgment and decision made by himself and Liu Jinghui. Huang Qiangmin is now the political commissar of the bureau, although he also holds the position of detachment leader of the criminal police detachment, he has very little interference in criminal cases. On the surface, he lets various squadrons play their autonomous combat power, but in fact, he gives Jiang Yuan the greatest degree of power.

Otherwise, if the Ningtai County Bureau appoints another criminal police detachment leader, it will have to run-in with Jiang Yuan. The key is that Jiang Yuan is not necessarily willing to run-in with newcomers, and a small county bureau is not easy to raise a great god like Jiang Yuan. At least after Chai Bureau left, the above was relatively Buddhist.

"I basically agree with your judgment. Is the visiting personnel enough? 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 Team Wu's First Squadron, it is still possible for now." Jiang Yuan replied.

Huang Qiangmin nodded and added: "I will reorganize the personnel. This kind of visit is easy to expand."

In fact, it will expand. If the early stage of the visit is relatively smooth, the case will be solved if it is solved. But if the early stage is not smooth, and 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 expanded. This part can be understood as drawing a circle. As the radius increases, the increase in the circle area is exponential.

Jiang Yuan nodded, feeling a little annoyed.

After all, he is still a technician, and even the shoulder straps he wears are gray shoulder straps used by professional technical police. This is also the work he is good at. As for visiting, it actually belongs to the traditional skills of criminal police, the so-called ability to solve cases proved by the cocoons on the soles of the feet.

"If there is no breakthrough in the short term, it may be necessary to draw two squadrons." Jiang Yuan paused and added: "I should have nothing to do in the past two days. If there is no result in this drowning case, I can help other squadrons handle cases first. See which squadron has needs."

Except for the newly built Taihe Working Group, there are no heavy cases in Ningtai locally. It is a bit exaggerated to say that the door is not closed at night, but except for sudden cases and passionate crimes, high-quality premeditated crimes and professional criminals can be said to be rare.

In this case, several criminal police teams are chasing cases in front. The homicide cold cases have been cleared by Jiang Yuan to 30 years ago, but among the eight major heavy cases, the remaining cold cases are still many, some of which involve serious injury, rape, arson, explosion, and the degree of evil is still very high, which is very worth tracing, but the difficulty of doing it is relatively high.

Because Jiang Yuan bears the role of resource support, he has done more big cases in other places before. He came back occasionally, and he couldn't just pick peaches. This time is the same. I believe there will always be a squadron that is chasing the previous cases and has technical needs to find Jiang Yuan.

Sure enough, after a while, Liu Wenkai delivered it to the door.

"I heard you are changing the bell here?" Liu Wenkai brought two people, brought notebooks and case files, and came over with a smile.

"What?" Jiang Yuan didn't understand.

"Political Commissar Huang's meaning, it doesn't cost money to click your bell, and you will pay more bells according to the time later." Liu Wenkai said seriously, and added: "It is said that this is not illegal."

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

Liu Wenkai hurriedly said: "The part that is not illegal is my guess!"

Huang Qiangmin: "Is the key that it is not illegal?"

"It is not illegal, is it not the key?" Liu Wenkai asked back.

Huang Qiangmin gave up: "Talk about the case."

"Oh, we have a robbery cold case here. The case occurred 12 years ago. The suspect took advantage of the closing time of a fruit supermarket to rob the shopkeeper, took away more than 7,000 yuan of sales income and several high-priced cigarettes, and then rode a bicycle to escape. The shopkeeper reported the case, and the police conducted a relatively detailed investigation..." Liu Wenkai came in a hurry, so while introducing the case, he put photos, and soon filled the table.

The police of Ningtai County Bureau are actually very familiar with how to use Jiang Yuan. The main thing is that they can't line up for the bell.

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 is still in the visiting period, and he has no ideas for the time being. As for the robbery cold case in front of him, the previous special case team also investigated seriously, but the criminal also prepared very seriously. From the few surveillance photos, it can be seen that the criminal is wearing a hat, sunglasses, mask, scarf, and gloves, and nothing is exposed from top to bottom.

The investigator also guessed that the suspect had tattoos based on this, and investigated a large number of people with previous records.

Jiang Yuan pondered and thought. From his point of view, the ideas of the previous investigators were no problem. The criminal performed very professionally in the robbery link, not only with complete equipment, clear escape routes, but also clean and neat robbery. Holding a throwing stick and a knife, he smashed the fruit supermarket counter with two bangs, and while taking cigarettes himself, he threatened the shopkeeper to take money.

The whole process cannot be said to be flowing, but there is definitely criminal experience. This homework is very practical, and practicing in advance will not practice this taste.

"How is it, any ideas? What do you need us to cooperate with?" Liu Wenkai was quite active. Don't look at it as his own technician. Huang Qiangmin said that the bell must be returned. Liu Wenkai naturally couldn't bear to waste a little bit.

Jiang Yuan thought for a while and said: "It can only be tried one by one. From the ideas you have done, I think you can go from the tool traces."

He now chooses investigation plans, many times from his own technical library. Of course, technicians are all such ideas. 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 throwing pots prepare pots in advance. They are all the same truth.

Jiang Yuan then followed the idea of tool traces, and according to the traces left at the scene, directly drew the appearance of the throwing stick and knife used by the suspect.

The picture came out, and then went to the tool trace database to search.

Searching like this, there are photos of several tools or tools involved in the case, appearing on the page.

Jiang Yuan compared them one by one, but didn't turn a few, and found that the front end of the throwing stick in a picture was slightly special.

Returning, it was a case of fighting that had been handled. Both sides of the fight, one side used a throwing stick, the other side used a chair, so each hit eighty boards...

"Catch these two people back and ask." Jiang Yuan called out the information of one side of the fighting case, looked at the height, age and other information, and was more certain.

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

"Good luck, the first method tried yielded results." Jiang Yuan said, beckoned Wang Chuanxing over, and said: "I remember that the drowning deceased had multiple injuries before death, which should be caused by violent beating."

"Can you find the tool based on this?" Wang Chuanxing was listening on the side, and immediately drew inferences from one instance.

Jiang Yuan shook his head: "It should be beaten by hand, but after being beaten, maybe you will go to buy some anti-inflammatory drugs, painkillers, etc. She may not necessarily go to a large hospital, and nearby small clinics are also possible."

"The clinic staff should have a deep impression of women who have been beaten within a month." Liu Jinghui was covering his head and thinking, and suddenly sat up. ===== CHAPTER 899 =====
