The Beijing-branded Audi A6 slowly drove into the yard of the Lanyue City Criminal Police Detachment.
Huang Qiangmin turned his legs and got out of the car. After adjusting his collar, Huang Qiangmin strode into the building of the Lanyue City Criminal Police Detachment.
This scene completely fell in the eyes of Dai Mingsheng and others.
Dai Mingsheng stood in front of the window, stared at the license plate of the Audi A6 for a long time, and said, "Did Huang Qiangmin specially transport this car from Ningtai County?"
"I heard it was driving from Changyang City. The two of them changed shifts and stayed up all night to drive here. Just like the Tang Minghuang shipped lychees, the two young men fell asleep as soon as they arrived. They were so tired." Deputy Lin Xunlei knew that Dai Dai
Mingsheng wanted to ask something, so he said directly: "His car always parked in Changyang City. He didn't drive it when he went back to Ningtai County. He only took it when he was in Changyang City."
"Changyang City Bureau didn't send him a car?" Dai Mingsheng asked.
Lin Xunlei said with a "you know" expression, "Why didn't I send it? The leader of the Changyang City Criminal Police Detachment is Yu Wenshu. He now always rides an old Passat when going out."
"Old Passat?" Dai Mingsheng now rides in a Passat and is a little sensitive.
Lin Xunlei chuckled and said: "Let's give away the new ones. Only the old ones can drive more stably."
Demingsheng did not laugh.
Huang Qiangmin knocked on the door and entered, smiling like a chrome-plated air intake grille.
…
Anatomy room.
On the anatomy bed, which could accommodate two people, dozens of burned bones were arranged in four trays.
Jiang Yuan was picking bones from an iron plate to three other small plates.
The four plates represent unsorted, burned bone fragments of women, burned bone fragments of men, and unclassified burned bone fragments.
The remaining third of the skull belonged to a woman and was placed on a separate plate.
Forensic doctors from the Lanyue Municipal Bureau also accompanied Jiang Yuan to pick up bones, but they could do little to help.
Distinguishing whether a body belongs to a male or a female is a basic subject in forensic anthropology. Distinguishing whether a bone belongs to a male or a female is a common but extremely difficult subject in forensic anthropology. As for distinguishing whether a bone fragment belongs to
Men and women are already very high-end or excessive issues in forensic anthropology. As for whether the burned bone fragments belong to men or women, this is purely a personal behavior of the forensic doctor!
The difference between the four is like driving a car, driving a good car, driving a racing car, and driving F1 to win the championship.
The difference in value is greater than the difference between dry green, bean green, floating flowers and full green. It is roughly equivalent to the extreme difference between a fat man, a strong man, a little wolfdog and a domineering CEO's handsome little wolfdog.
If you just bring a complete corpse over, an ordinary forensic intern can speak eloquently, but if the leader brings over a bone fragment and asks the ordinary forensic doctor whether it is a male or female, the first thing that the ordinary forensic doctor will think about is: is it human?
bones? And, are leaders human beings?
From this perspective, it is normal for the forensic doctor from the Lanyue City Bureau to be unable to determine that these bone fragments came from two people.
Of course, from another perspective, it is normal for Jiang Yuan to pick up the 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 was the two forensic doctors from Lanyue City.
There were 43 pieces of burnt bones on a plate, and Jiang Yuan spent more than an hour classifying them all, including 12 female pieces, 7 male pieces, and 24 unclassified pieces.
It seems that there are still 24 burnt bone fragments that have not been classified, but the two forensic doctors from Lanyue City really couldn't hold it any longer. The more senior Yang Zhaolin waited for Jiang Yuan to complete the classification, and then stretched his body before asking: "Captain Jiang."
, you classified based on the information on the bone fragments?"
"It must be classified by the information on the calcaneus." Jiang Yuan smiled, and suddenly felt that this was not good. The first round of IQ output has been completed, Jiang Yuan put some EQ online, turned around and said warmly: "To be specific, men and women
Women’s bones have their own characteristics, such as roughness. Men’s bones are usually rougher, while women’s bones are smoother to the touch.”
Yang Zhaolin said "en". The principle is simple, but is it used in this way?
To use an analogy, if you mix the fish bones of a carp and the fish bones of a grass carp together, how can you tell who is who by just looking at the smoothness and hardness of the fish bones?
This is still a much different species determination.
Jiang Yuan immediately recognized Yang Zhaolin's doubts and said: "This case is different from normal burned bone fragments because a female skull was left at the scene."
"Huh?" Yang Zhaolin didn't hear anything special at all.
Jiang Yuan said patiently: "With the woman's skull, we can actually establish a simple coordinate system, based on which we can judge the general characteristics of the woman's bones in this environment. For example, the smoothness and smoothness we just mentioned
It is also closely related to the density of the bones. In addition, the thickness of the bones can also be seen from the woman’s skull.”
Jiang Yuan: "We establish a coordinate system for the woman's bones. The burned bone fragments that match the female's bones in all aspects can be identified as belonging to the woman. The bones that do not match the female's bones can be classified again, and the consistency will be relatively strong.
If you can tell the characteristics of bones, they belong to another person. It can be seen that in terms of bone quality, it is obviously more male-oriented..."
Jiang Yuan: "In addition, cross-sections are always a treasure for forensic medicine. From the cross-sections of these bone fragments, some masculine characteristics can be clearly found. These bones can be directly identified as male. And, if necessary, you can
Based on this, a simple skeletal coordinate system belonging to men is established, which will be useful if a third person is burned to death at the scene."
Yang Zhaolin was surprised: "Is there a third person?"
Jiang Yuan shook his head: "It seems that there shouldn't be 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 flame temperature of the site, surrounding conditions, etc., and it happens that there are two men and women.
For a corpse, just separate the two people, there is no need to refine the coordinate system."
Yang Zhaolin felt that he understood something. He said "Oh" and asked: "How was this coordinate system established? I didn't see you doing this..."
"Just establish it in your mind." Jiang Yuan smiled and said: "Forensic anthropology, after all, some things need to be learned through experience."
"Ah?" Yang Zhaolin really couldn't hold himself any longer.
There are indeed many empirical components in forensic anthropology, just like the skills of mechanics in a factory. The scientific parts are all written in the mechanics' manuals, but if you just look at the mechanics' manuals, there must be endless problems in the production process.
But when it comes to learning, the things in technician manuals are actually easier to learn. They are like college textbooks. If you read more, you can always understand them.
Experience is not so easy to learn. It may be difficult, it may not be difficult, but without a master, many people may spend their entire lives summarizing it.
The younger forensic doctor next to him could see clearly. He gave Yang Zhaolin a hand and said, "Master, haven't you seen the forensic anthropology cases done by Jiang Yuan before?"
"Look...I've seen it too." Yang Zhaolin is the kind of person who has to go home after get off work. His overtime hours are too short, so naturally he doesn't have time to read journals and bulletins.
The young forensic doctor whispered: "I'll look back and show it to you, and you'll understand."
At this time, Yang Zhaolin took two steps back from the front, a little farther away from Jiang Yuan, and asked his apprentice: "If you understand anything, just tell me directly."
"I understand..." The young forensic doctor hesitated for a moment and whispered: "I understand that some people don't take the exam at Peking University. It's not because they don't like it."
Yang Zhaolin was stunned for a moment, and it took him a while to figure it out. He then raised his foot and gave it to his apprentice.
The apprentice said aggrievedly: "Master, you are dirty!"
Yang Zhaolin: "Okay, you wait until I wash it off..."
…
squeak……
In the quiet anatomy room, there was suddenly the sound of the door opening.
Mu Zhiyang, who was standing behind Jiang Yuan, was excited and put his hand on the gun on the spot.
The three forensic doctors present looked unmoved. The autopsy room is the forensic doctor's office, and it was normal for people to come to the office. There was no one who touched the gun just because the office door was pushed open.
Dai Mingsheng and Huang Qiangmin walked in hand in hand, followed by policemen such as Jian Louyuan and Wei Shijin, all with smiles that seemed both genuine and fake on their faces.
"Jiang Yuan, how is this case? Can it continue?" Dai Mingsheng asked Jiang Yuan with concern.
"The classification of the bone fragments has been completed. The next step is to find a way to determine the identity of the deceased." Jiang Yuan did not answer directly, but talked about the current progress.
Dai Mingsheng frowned slightly: "Can you confirm your identity?"
There are many unknown corpses whose identities cannot be determined, not to mention the trouble the criminal police team encounters in this regard.
Jiang Yuan looked at Huang Qiangmin's eyes and said, "It's hard to say yet, but I think there is a basis for doing it."
Upon seeing this, Huang Qiangmin immediately added: "The Taihe working group established by Jiang Yuan in Ningtai specializes in drowning cases. Determining the identity of the deceased is a professional category."
"That's good, that's good." Of course Dai Mingsheng hoped for a breakthrough. He nodded repeatedly, then looked at Jian Louyuan and said, "In that case, I suggest reorganizing the task force. Dongxi Lake Corpse Burning Case,
Just use this name to make it clear at a glance.”
"Yes!" Jian Louyuan agreed, then hesitated and said, "Dai Zhi, don't you wait for specific clues to come out before you reorganize the task force?"
The most important KPI of the criminal police is the case detection rate. Therefore, many people report small cases or economic cases, and it is difficult to file a case. The task force is not reorganized just because it is said to be reorganized. Based on Jian Louyuan’s idea, first follow the instructions of Jiang Yuan’s leadership of the task force
Once the model is running, just seize the time to make preliminary preparations. Instead, we can wait until we have clues and directions for the official listing and reorganization.
Dai Mingsheng glared at Jian Louyuan and said, "Just do whatever I ask you to do!"
"Yes." Jian Louyuan quickly stood up at attention, and was then taken out of the anatomy room by his subordinates.
Jian Louyuan felt a little embarrassed, so she complained in front of her subordinate (pseudo) Wei Shijin, saying: "Dai Zhi is too anxious. The task force will be reorganized by then. If the case cannot be solved for a long time, we will be laughed at again."
Wow, are you stupid?"
Wei Shijun comforted the team leader: "You are the one who is stupid. What Dai Zhi is worried about is that Jiang Yuan has solved this case before our task force has been reorganized!"
