Chapter 1099 Reorganization Task Force
A Beijing-licensed Audi A6 slowly drove into the yard of the Lanyue City Criminal Police Detachment.
Huang Qiangmin stepped out of the car, straightened his collar, and strode into the building of the Lanyue City Criminal Police Detachment.
This scene was completely seen by Dai Mingsheng and others.
Dai Mingsheng stood in front of the window, staring 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 they drove here from Changyang City. Two people took shifts and drove here through the night. Just like Emperor Tang Minghuang transporting lychees, the two young men fell asleep as soon as they arrived. They were just as tired as before." Deputy Lin Xunlei knew what Dai Mingsheng wanted to ask, and said directly, "His car later stopped regularly in Changyang City. He didn't drive it back to Ningtai County. He just drove it when he went to Changyang City."
"Didn't the Changyang Municipal Bureau send him a car?" Dai Mingsheng asked.
Lin Xunlei had a look of "you know what I mean" on his face, and said, "How could he not send it? The captain of the Changyang City Criminal Police Detachment is Yu Wenshu, and he always drives an old Passat when he goes out now."
"Old Passat?" Dai Mingsheng himself was currently riding in a Passat and was a little sensitive.
Lin Xunlei laughed and said, "Send the new one out. The old one will be more stable."
Dai Mingsheng didn't laugh.
Huang Qiangmin knocked on the door and came in, his smile looking like a chrome grille.
……
Anatomy room.
On the dissecting bed that could accommodate two people, dozens of bones remaining after being burned were arranged into four plates.
Jiang Yuan was picking bones from an iron plate and putting them into three other small plates.
The four plates represent the unsorted, female burnt bone fragments, male burnt bone fragments, and burnt bone fragments that cannot be classified.
The remaining third of the skull belonged to a female and was placed on a separate plate.
The forensic doctor from the Lanyue Municipal Bureau also accompanied Jiang Yuan in picking up bones, but he could provide little help.
Distinguishing whether a corpse belongs to a man or a woman is a basic subject in forensic anthropology. Distinguishing whether a piece of bone belongs to a man or a woman is a common but extremely difficult subject in forensic anthropology. As for distinguishing whether a piece of bone fragment belongs to a man or a woman, it is already a very advanced or excessive problem in forensic anthropology. As for whether a burned bone fragment belongs to a man or a woman, it 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 winning an F1 championship.
The difference in value is greater than that between dry green, bean green, floating flower and full green. It is roughly equivalent to the difference between a fat man, a strong man, a little wolf dog and a domineering president's handsome little wolf dog.
If you bring a complete corpse to a normal forensic doctor, he or she can explain it clearly. But if the leader brings a bone fragment to a normal forensic doctor and asks him or her whether it is a man or a woman, the first thing that the normal forensic doctor will think about is: Is this a human bone? And, is the leader a human?
From this perspective, it is normal that the forensic doctor of Lanyue City Bureau could not 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 them, think for a moment, and then classify them into male or female.
The only thing that was not normal at the scene was the forensic doctors from Lanyue City. Two.
Jiang Yuan spent more than an hour sorting out the 43 burnt bone fragments on a plate, including 12 from women, 7 from men, and 24 unclassified pieces.
It seemed that there were still 24 burnt bone fragments that had not been classified, but the two Lanyue City forensic doctors could no longer hold back. Yang Zhaolin, who had more seniority, waited for Jiang Yuan to finish the classification. When he stretched his back, he asked, "Captain Jiang, did you classify according to the information on the bone fragments?"
"It must be the information classification on the heel bone slice." Jiang Yuan smiled, and then suddenly felt that this was not a good idea. The first round of IQ output has been completed. Jiang Yuan has put on some emotional intelligence and turned around to say gently: "Specifically speaking, male and female bones have their own characteristics. For example, in terms of roughness, male bones are usually rougher, while female bones feel smoother."
Yang Zhaolin said "Yeah", the principle is simple, but is it used in this way?
To make an analogy, if you mix the fishbone of a carp and the fishbone of a grass carp together, how can you tell which is which just by looking at the smoothness and hardness of the fishbones?
This is still a much different species determination.
Jiang Yuan immediately recognized Yang Zhaolin's doubts and said, "This case is different from the normal bone fragments after burning. Because a female skull was left at the scene."
"Huh?" Yang Zhaolin didn't hear anything special.
Jiang Yuan said patiently: "With the skull of this woman, we can actually establish a simple coordinate system to determine the general characteristics of the woman's bones in this environment. For example, the smoothness we just mentioned is closely related to the density of the bones. In addition, the thickness of the bones can also be seen from the skull of this woman."
Jiang Yuan: "We set up a coordinate system for the woman's bones. The burnt bone fragments that match all the requirements can be identified as belonging to the woman. The bones that do not match the woman's can be classified. The ones with strong consistency and distinguishable bone characteristics belong to another person. It can be seen that in terms of bone quality, they are obviously more inclined to men..."
Jiang Yuan: "In addition, cross sections are always a treasure for forensic doctors. From the cross sections of these bone fragments, we can clearly find some masculine characteristics. For these bones, they can be directly identified as male. And, if necessary, we can establish a simple male bone coordinate system based on this. If there is a third person burned to death at the scene, it will come in handy at this time."
Yang Zhaolin was startled: "Is there a third person?"
Jiang Yuan shook his head: "It seems that there is no such thing now. In fact, there is no need to establish a second coordinate system. Because it is all based on environmental conditions, that is, the temperature of the flames at the scene, surrounding conditions, etc. It just so happens that there are two bodies, a man and a woman, so we can just separate the two people. There is no need to refine the coordinate system."
Yang Zhaolin seemed to understand a little bit, and said "Oh", and asked: "How is this coordinate system established? I didn't see you do this..."
"Just build it up in your mind." Jiang Yuan smiled and said, "Forensic anthropology is something that you need to rely on experience to learn."
"Ah?" Yang Zhaolin couldn't hold it in any longer.
There are indeed many empirical components in forensic anthropology, just like the skills of a technician in a factory. The scientific part is all written in the technician's booklet, but if you only look at the technician's booklet, you will find that there will be endless problems in the production process.
But when it comes to learning, the things in the technician manual are actually easier to learn, just like college textbooks, if you read them more often, you will always be able to understand them.
Experience is not so easy to learn. It may be difficult, or it may not be difficult, but without a master, many people may spend their entire lives summing up.
The younger forensic doctor next to him understood it clearly. He pulled Yang Zhaolin and said, "Master, haven't you seen the forensic anthropology cases done by Jiang Yuan before?"
"I have...read it." Yang Zhaolin is the kind of person who goes home after get off work. His overtime hours are too short, so naturally he has no time to read journals and bulletins.
The young medical examiner whispered, "I'll go back and show it to you, and you'll understand."
Yang Zhaolin took two steps back from the front, a little further away from Jiang Yuan, and asked his apprentice: "What do you understand? Just tell me directly."
"I understand..." The young forensic doctor hesitated for a moment and whispered, "I understand. Some people don't apply to Peking University, not because they don't like it."
Yang Zhaolin was stunned for a moment, and it took him a while to figure out what was going on. He then raised his foot and hit his apprentice.
The apprentice said aggrievedly: "Master, it's dirty!"
Yang Zhaolin: "Okay, wait for me to wash it clean..."
……
squeak……
In the quiet autopsy room, there was a sudden sound of a door opening.
Mu Zhiyang, who was standing behind Jiang Yuan, was so excited that he immediately reached for the gun.
The three medical examiners present all looked unmoved. The autopsy room was the medical examiner's office, and it was normal for people to come to the office. No one would reach for a gun just because the office door was pushed open.
Dai Mingsheng and Huang Qiangmin entered together, followed by Jian Louyuan, Wei Shijian and other police officers, all with fake smiles on their faces.
"Jiang Yuan, how is this case going? Can you continue working on it?" Dai Mingsheng asked Jiang Yuan with concern.
"The classification of 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 the identity?"
There are many unidentified corpses whose identities cannot be confirmed, not to mention the troubles the criminal police team encounters in this regard.
Jiang Yuan looked at Huang Qiangmin's eyes and said, "It's hard to say now, but I think there is a basis for doing it."
Huang Qiangmin immediately added, "The Taihe Working Group that Jiang Yuan set up in Ningtai specializes in drowning cases. Determining the identity of the deceased is a professional area."
"That's good, that's good." Dai Mingsheng certainly hoped for a breakthrough, nodded repeatedly, looked at Jian Louyuan, and said: "In this case, I suggest that we reorganize the task force. Let's use this name for the Dongxi Lake Corpse Burning Case, which will make it clear at a glance."
"Yes!" Jian Louyuan responded, then hesitated for a moment and said, "Dai Zhi, why don't you wait for specific clues to come out before reorganizing the task force?"
The most important KPI for criminal police is the crime solving rate. Therefore, many people report small cases or economic cases, but it is difficult to file a case. The task force cannot be reorganized just like that. According to Jian Louyuan's idea, it should be operated according to the model of Jiang Yuan leading the task force, and make good use of the time to make preliminary preparations. On the contrary, the formal reorganization can be discussed after there are clues and directions.
Dai Mingsheng glared at Jian Louyuan fiercely and said, "Just do whatever I tell you to do!"
"Yes." Jian Louyuan quickly stood at attention and was then led out of the autopsy room by his guard Shi Jian.
Jian Louyuan felt a little embarrassed, so he complained to his subordinate (fake) Wei Shijian, "Dai Zhi is too anxious. If we reorganize the task force and fail to make a breakthrough in the case, we will be laughed at again. How stupid!"
Wei Shijian comforted the captain: "You are the fool. Dai Zhi is worried that Jiang Yuan has solved the case before our task force has been reorganized!"
