Chapter 1084: Reorganizing the Special Investigation Team

The Audi A6 with Beijing license plates slowly drove into the courtyard of the Lanyue City Criminal Police Detachment.

Huang Qiangmin tilted his leg and got out of the car. After straightening his collar, Huang Qiangmin walked into the building of the Lanyue City Criminal Police Detachment with big strides.

This scene fell completely into the eyes of Dai Mingsheng and others.

Dai Mingsheng stood by the window, stared at the license plate of the Audi A6 for a long time, and said: "Huang Qiangmin specifically transported this car from Ningtai County?"

"I heard it was driven from Changyang City. Two people took turns, driving overnight. Like Emperor Tang Ming transporting lychees, the two young people came and fell asleep, tired like anything." Deputy Lin Xunlei knew what Dai Mingsheng wanted to ask, and said directly: "This car of his is fixedly parked in Changyang City later. He doesn't drive it when he returns to Ningtai County, just sits in it when he is in Changyang City."

"Did the Changyang City Bureau not send him a car?" Dai Mingsheng asked.

Lin Xunlei had an expression of "you know", and said: "How could they not send one? The captain of the Changyang City Criminal Police Detachment is Yu Wenshu. He now goes out in an old Passat."

"Old Passat?" Dai Mingsheng himself is now sitting in a Passat, a bit sensitive.

Lin Xunlei chuckled and said: "The new one must have been sent out. The old one can be driven more stably."

Dai Mingsheng didn't laugh.

Huang Qiangmin knocked on the door and entered, smiling like a chrome-plated intake grille.

Dissection room.

On the dissection table that can sleep two people, dozens of bone fragments remaining after burning were arranged in four plates.

Jiang Yuan was picking bones from one iron plate to the other three small plates.

The four plates represent unsorted, female burnt bone fragments, male burnt bone fragments, and unclassified burnt bone fragments.

The remaining one-third of the skull belongs to a female and was placed separately in another plate.

The forensic doctor of the Lanyue City Bureau also accompanied Jiang Yuan to pick bones, but there was little help he could provide.

Distinguishing whether a corpse is male or female is a basic subject in forensic anthropology. Distinguishing whether a bone belongs to a male or female is common in forensic anthropology, but it is extremely difficult. As for distinguishing whether a bone fragment belongs to a man or a woman, it already belongs to a very high-end or excessive problem in forensic anthropology. As for whether the burnt bone fragments belong to a male or female, this purely belongs to the personal behavior of the forensic doctor!

The difference between the four is like driving, driving a good car, driving a racing car, and winning the F1 championship.

Its value difference is greater than the difference between Ganqing, Douqing, Piaohua, and Manlv. It is about equivalent to the extreme difference between a fat man, a strong man, a little wolf dog, and a domineering president handsome little wolf dog.

If you take a complete corpse, an ordinary forensic intern can talk about it, but if the leader takes a bone fragment and asks an ordinary forensic doctor whether it is male or female, the first thing the ordinary forensic doctor thinks of is: Is this a human bone? And, is the leader a human?

From this point of view, it is normal for the forensic doctor of the Lanyue City Bureau to be unable to judge that these bone fragments come from two people. Of course, from another point of view, it is also normal for Jiang Yuan to pick up bone fragments, observe the bone fragments, think for a moment, and classify the bone fragments into male or female.

The only abnormal thing at the scene is the forensic doctor of Lanyue City. Two of them.

43 burnt bone fragments in a plate were all classified by Jiang Yuan in more than an hour, of which 12 were female, 7 were male, and 24 were unclassified.

It seems that there are still 24 burnt bone fragments unclassified, but the two forensic doctors in Lanyue City really couldn't hold it anymore. Yang Zhaolin, who had a longer seniority, waited for Jiang Yuan to finish the classification and stretch, before asking: "Team Leader Jiang, did you classify them according to the information on the bone fragments?"

"It must be classified according to the information on the bone fragments." Jiang Yuan smiled, but immediately felt that this was not good. The first round of IQ output had been completed, Jiang Yuan went online with part of his emotional intelligence, turned around and said gently: "Specifically, male and female bones have their own characteristics. For example, in terms of roughness, male bones are usually rougher, and female bones feel smoother."

Yang Zhaolin said "En". The truth is shallow, but is it used like this?

To make a metaphor, if you mix the fish bones of a carp and the fish bones of a grass carp together, just looking at the smoothness and hardness of the fish bones, how to distinguish who is who?

This is still a species determination with a much larger difference.

Jiang Yuan realized Yang Zhaolin's doubt for the first time, and said: "This case is different from the burnt bone fragments after normal burning. Because the female skull was left at the scene."

"En?" Yang Zhaolin didn't hear anything special at all.

Jiang Yuan said patiently: "With the skull of the female, we can actually establish a shallow coordinate system, and judge the general characteristics of the female's bones in that environment based on this. For example, the smoothness we just mentioned, smoothness is also closely related to the density of the bones. In addition, the thickness of the bones can also be seen from the skull of the female."

Jiang Yuan: "We establish a coordinate system of the female's bones. Burnt bone fragments that meet the characteristics in all aspects can be identified as belonging to the female. And bone fragments that do not meet the female's bones, and then classify them, those with strong consistency and can distinguish the bone quality characteristics, belong to another person. It can be seen that in terms of bone quality, it is obviously more biased towards male..."

Jiang Yuan: "In addition. The cross-section is always the wealth of the forensic doctor. From the cross-section of these bone fragments, some masculine characteristics can be obviously found. For these few bone fragments, they can be directly identified as male. And, if necessary, a shallow coordinate system belonging to male bones can be established based on this. If a third person is burned to death at the scene, this can play a role at this time."

Yang Zhaolin was shocked: "Is there a third person?"

Jiang Yuan shook his head: "It seems there is no one now. In fact, there is no need to establish a second coordinate system. Because they are all based on environmental conditions, that is, the fire temperature at the scene, surrounding conditions, etc., and it happens to be two corpses, male and female, just separate the two people, there is no need to refine the coordinate system."

Yang Zhaolin felt that he understood a little, "Oh" and asked: "How is this coordinate system established? Didn't see you do this..."

"Just establish it in your mind." Jiang Yuan smiled and said: "Forensic anthropology, after all, has to rely on experience to learn."

"Ah?" Yang Zhaolin really couldn't hold it anymore.

The experience component in forensic anthropology is indeed quite a lot. This is like the technology of technicians in a factory. The scientific part is written in the technician's manual, but if you only look at the technician's manual, the problems in the production process will definitely be endless.

But to say learning, in fact, the things in the technician's manual are relatively easy to learn, just like the textbooks in university. If you read more, you will always be able to read through.

Experience is not so easy to learn. Maybe it's difficult, maybe it's not difficult, but without a master, many people may have to summarize it for a lifetime.

The younger forensic doctor next to him saw it clearly, pulled Yang Zhaolin, and said: "Master, haven't you seen the forensic anthropology cases done by Jiang Yuan before?"

"Look... I have also seen it." Yang Zhaolin is the kind of person who wants to go home after work. The overtime time is too short, so naturally, there is no time to read journals and bulletins.

The young forensic doctor whispered: "I will find it for you later, and you will understand."

Yang Zhaolin retreated two steps from the front at this time, stayed a little further away from Jiang Yuan, and asked the apprentice: "Understand what, you say it directly."

"Just understand..." The young forensic doctor hesitated for a moment and whispered: "Just understand, some people don't take the Peking University exam, not because they don't like it."

Yang Zhaolin was stunned for a while, and it took a long time to figure it out, raised his foot and gave the apprentice a kick.

The apprentice said aggrievedly: "Master, dirty!"

Yang Zhaolin: "Okay, you wait for me to wash it clean..."

Zhi...

In the quiet dissection room, the sound of the door opening suddenly came.

Mu Zhiyang, who was standing behind Jiang Yuan, was so excited that he touched his gun on the spot.

The three forensic doctors present were unmoved. The dissection room is the forensic doctor's office. It is normal for people to come to the office. No one would touch a gun because the office door was pushed open.

Dai Mingsheng and Huang Qiangmin entered together, followed by Jian Louyuan and Wei Shiyan and other police officers, all with smiles that were true or false.

"Jiang Yuan, how is this case? Can it continue?" Dai Mingsheng asked Jiang Yuan with concern.

"The bone fragment classification has been completed. Next, we still have to find a way to determine the identity of the deceased." Jiang Yuan didn't answer directly, but said the progress now.

Dai Mingsheng frowned slightly: "Can the identity be determined?"

There are many unidentified corpses that cannot determine the identity, and the trouble encountered by the criminal police team in this regard is even more needless to say.

Jiang Yuan looked at Huang Qiangmin's eyes and added: "It's hard to say now, but I think there is a basis for continuing."

Huang Qiangmin saw this and immediately added: "Our Jiang Yuan's Taihe working group established in Ningtai is specifically for drowning cases. Determining the identity of the deceased belongs to the professional category."

"That's good, that's good." Dai Mingsheng naturally hoped to have a breakthrough, nodded repeatedly, then looked at Jian Louyuan and said: "Since this is the case, I suggest reorganizing the special investigation team. Dongxi Lake corpse burning case, just use this name, clear at a glance."

"Yes!" Jian Louyuan responded, then hesitated for a moment, and said: "Captain Dai, don't wait for specific clues to come out before reorganizing the special investigation team?"

The most important KPI for criminal police is the case-solving rate. Therefore, many people report small cases or economic cases, which are difficult to file. The special investigation team is not said to be reorganized just by reorganization. According to Jian Louyuan's idea, first run according to the mode of Jiang Yuan leading the special investigation team, and seize the time to make preliminary preparations. Instead, formal listing and reorganization can wait until there are clues and directions.

Dai Mingsheng glared at Jian Louyuan fiercely and said: "Do whatever I tell you to do!"

"Yes." Jian Louyuan hurriedly stood at attention, and then was taken out of the dissection room by his subordinate (pseudo) Wei Shiyan.

Jian Louyuan felt a little embarrassed, so he complained to his subordinate (pseudo) Wei Shiyan: "Captain Dai is too anxious. When the special investigation team is reorganized, if the case cannot be broken for a long time, we will be laughed at again. Is he stupid!"

Wei Shiyan comforted the captain: "The stupid one is you. Captain Dai is worried that our special investigation team hasn't been reorganized yet, and Jiang Yuan has already solved the case!" ===== CHAPTER 1085 =====

Wei Shikan comforted the team captain: "You're the silly one. What Deputy Dai is worried about is that Jiang Yuan will have already solved this case before our special task force has even finished reorganizing!"
