"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 in the first place.
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 body, Jiang Yuan can get the approximate face of the deceased through skull 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 of that of an ordinary police station.
The Forensic Sketching of LV6 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 whether it is rotten or not. It is more convenient to rot into bones. The advantages of Forensic Sketching are
It’s fast. It doesn’t have to be a week-long job like cranial reconstruction surgery. It only takes a few strokes, ten minutes, or at most an hour to produce a picture. Moreover, the accuracy of the drawing is higher than that of cranial reconstruction surgery.
, the success rate when applied to face recognition is even higher.
However, as soon as the Taihe working group started, a 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 already 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 appearance at this time. 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 of photos are criminal photos. Photographers who specialize in taking pictures of prisoners and dead people. In the era before digital cameras, if you want every photo to perfectly reflect the characteristics of the face, you have to practice. As for whether it looks good or not, it depends on the identity.
Before beautification was allowed in ID photos, there were a few people who were really good-looking.
The Huang Qiangmin drawn by Jiang Yuan is certainly not good-looking, but Huang Qiangmin also looks 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 gradually frowned: "You didn't even get it out?"
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 rarely interfered in criminal cases. On the surface, he is letting it go
Each squadron exerts its independent combat power, which actually delegates power to Jiang Yuan to the greatest extent.
Otherwise, if the Ningtai County Bureau appoints another criminal police captain, it will have to run in with Jiang Yuan. The key is that Jiang Yuan may not be willing to run in with the newcomer, and a small county bureau actually has to support a great figure like Jiang Yuan.
It's easy, at least after Director Chai left, it became more Buddhist-like.
"I basically agree with your judgment. Are there enough visiting personnel? 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. Even the epaulettes he wears are gray epaulettes used by professional technical police. This is also the job he is good at. As for visiting, it is actually a traditional skill of criminal policemen, so-called using the soles of their feet.
The speed of cocoon proves the strength of solving the case.
"If there is no breakthrough in the short term, we may need 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, there are still many backlogs for the other seven of the eight major serious crimes, 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 shoulders the role of resource support, he has been working on big cases in other places before. Occasionally, when he comes back, he can't just pick peaches. It's the same this time. I believe there will always be a squadron chasing the front.
The case was hotly pursued, and Jiang Yuan was approached for technical needs.
My dear, there is more to come after this chapter. Please click on the next page to continue reading. There will be more exciting chapters later!
Sure enough, within a short time, Liu Wenkai came to the door.
"I heard that you are changing the clock here?" Liu Wenkai came over with two people, notebooks and files, laughing.
"What?" Jiang Yuan didn't understand.
"What Political Commissar Huang means is that there is no charge for clicking your clock, and you can pay for more clocks 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 about not breaking the law was just a guess on my part!"
Huang Qiangmin: "Isn't the key to not breaking the law?"
"If it's not illegal, isn't it important?" Liu Wenkai asked rhetorically.
Huang Qiangmin gave up: "Let's talk about the case."
"Oh, we have a robbery case here. The case occurred 12 years ago. The suspect took advantage of the closing time of a fruit supermarket to rob the owner and took away more than 7,000 yuan in sales revenue and many cartons of high-priced cigarettes.
He fled on a bicycle. The shop owner reported the case, and the police conducted a more detailed investigation..." Liu Wenkai came here in a hurry, so while introducing the case, he put photos on the table, and the table was quickly filled.
The police in Ningtai County Bureau are actually very skilled in how to use Jiang Yuan. The main problem is that they can't queue up.
Liu Wenkai knew that Jiang Yuan could be used for two days, so he naturally brought all the equipment he could.
Jiang Yuan just looked at the photos one by one.
While the drowning case was still being visited, he had no idea for the time being. As for the backlog of robberies in front of him, the previous task force was quite serious in their investigation, but the prisoners were also very serious in their preparations. It can be seen from a few surveillance photos that the prisoners were wearing hats and sunglasses.
With the mask and scarf and gloves, no part of my body was exposed.
The investigators also speculated that the suspect had tattoos and investigated a large number of 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 prisoner behaved very professionally during the robbery. Not only was the equipment fully equipped, the escape route was clear, the robbery was also clean and neat.
He threw a stick and a knife and smashed the counter of the fruit supermarket with two clicks. While getting cigarettes himself, he threatened the shopkeeper and took money.
The whole process cannot be said to be smooth and smooth, but it is certain that you have criminal experience. This homework is very practical, and you can't get it right if you practice it in advance.
"How's it going? Do you have any ideas? Is there anything we need to cooperate with?" Liu Wenkai was very positive. Even though he was his own technician, Huang Qiangmin said that the clock must be returned, so Liu Wenkai was naturally reluctant to waste a little bit.
Jiang Yuan thought for a while and said: "We can only try the same thing. Judging from the ideas you have done, I think we can start from the tool marks."
When he chooses an investigation plan now, he often chooses it from his own technical library. Of course, technicians all have this idea. When faced with the same problem, those who are good at Java will use Java, and those who are good at C will use C.
If you are good at throwing the pot away, prepare the pot in advance. The same principle applies.
Jiang Yuan then followed the idea of tool marks and directly drew the appearance of the stick and knife used by the suspect based on the marks left at the scene.
After the picture comes out, search in the tool trace database.
After such a search, multiple tools or photos of the tools involved appeared on the page.
Jiang Yuan compared them one by one, but after flipping through a few pages, he found that the front end of the swing stick in a picture was a little special.
When I came back, I saw that this was a closed fight. One party used a stick and the other used a chair, so each of them hit eighty big boards...
"Catch these two people and ask them." Jiang Yuan called up the information of one party in the fight and looked at the height, age and other information to become more sure.
Liu Wenkai then got two pieces of printing paper, looked at the time, and was a little surprised after all: "It came out so soon?"
"Luckily, the first method I tried produced results." Jiang Yuan spoke, waving to Wang Chuanxing, and said: "I remember that the drowned deceased had many wounds during his lifetime, which should be caused by violent beatings.
."
"Can we find tools based on this?" Wang Chuanxing was listening nearby, and he immediately drew inferences.
Jiang Yuan shook his head: "It should have been done by hand, but after being beaten, she might buy some anti-inflammatory drugs, painkillers, etc. She might not necessarily go to a big hospital, but maybe a small clinic nearby."
"Clinic staff should be very impressed by women who have been beaten within a month." Liu Jinghui was thinking with his head covered, but now he sat up.
