Huang Qiangmin used his superb skills to temporarily get rid of the encirclement of several Qingshi City criminal policemen. He went to Jiang Yuan and asked: "How do you say it?"
"Hmm... Let's look at it now, let's look at the simple dismemberment case." Jiang Yuan lowered his head and flicked his PAD, quickly looked through the photos of the corpse, and then said: "There should be quite a lot of clues."
"What about the difficulty?"
"Weak LV3." After all, this is a case of dismemberment. Although there are not many "dismemberments", it is still broken. Giving it LV3 is a sign of respect for this type of case.
"That's okay." Huang Qiangmin breathed a sigh of relief. He occasionally heard expressions like LV1 and LV3 from Jiang Yuan's mouth, and now he basically understood their meaning. He even felt that this classification method was quite good.
The situation was immediately understood, and the guidance for the negotiation was clear.
Otherwise, just say it is difficult, very difficult, difficult to do, etc. Who knows which is really difficult.
Jiang Yuan nodded slightly: "It's not difficult at all. According to our normal process, there is a high probability that we can do it, but there is also a possibility that we can't do it. If we can't do it, the difficulty will be high."
If you can complete the task according to the script, it is not too difficult a task.
But from another perspective, people and teams who can perform tasks according to the script are themselves scarce. For example, out of the 150 points in the college entrance examination mathematics, 90 points are based on the questions according to the script, and among the annual college entrance examination people, those who can achieve
At this level, it is obviously less than 60%.
Therefore, most people in this world do not even have the ability to follow a script. Those stupid people in the workplace, those stupid drivers on the road, and those stupid comments on the Internet are all examples of low-level sliding.
"Is Political Commissar Huang whispering to our Captain Jiang?"
Fang Gang, the criminal police detachment leader of Qingshi City Bureau, came over with a smile.
"Your case is too difficult. Jiang Yuan will discuss with me how to explain the situation to you. Your support must be guaranteed. Otherwise, if we don't talk about whether the case can be solved, the case will be delayed easily.
." Basically nothing Huang Qiangmin said is true, but it is true that the police can deceive people when handling cases.
Fang Gang looked solemn and thought to himself, you just collected two years of membership dues and now you start talking about the difficulty...
Fang Gang said: "The support that should be given can definitely be guaranteed, but our funds are also limited and cannot be said to be endless..."
"Old Fang, I don't mean to ask you to add more money." Huang Qiangmin stopped Fang Gang and waved his hand: "I just want you to guarantee the funds for handling the case. Have you watched the news broadcast a few days ago?"
"I took a look and saw Jiang Yuan's face. I pointed it out to my family."
"Right. Our Jiang Yuan's reputation is really not built on." Huang Qiangmin's expression changed when he said this: "So, this is also a guarantee. Wherever you go, you can still find criminal investigation experts like our Jiang Yuan.
?”
In the past, Huang Qiangmin would not have said this. He would have said fingerprint expert or forensic expert, but now, he loudly said the word "criminal investigation expert".
Everyone present, especially the detectives from the Qingshi City Criminal Investigation Detachment, naturally accepted it.
On Fang Gang's face, he nodded with admiration and relief: "If expert Jiang Yuan thinks it is necessary, we will not hesitate and will fully cooperate."
If the criminal investigation expert is regarded as a weapon, then Jiang Yuan's weapon is already a famous weapon at the level of the Qinglong Yanyue Sword. If you can use it, why be stingy.
"Collect water along the upstream. Every 50 meters, take 20 kilometers. The water samples collected are sent to the laboratory for diatom analysis. In addition..." Jiang Yuan turned to Wang Chuanxing and said: "Invite Professor Su Lei and the others to come over.
Say I have a project here, which is similar to a research project to establish a 20-kilometer-long diatom lineage in the upper reaches of the Taihe River."
Although the Taihe Working Group has only been recognized by a few cities, mainly because it has only received membership fees from these cities. However, this system has basically been established.
For drowning corpses, using diatoms to determine where the corpse entered the water is still very effective. Not every corpse is effective, but it can be effective for at least 30% of the corpses.
This number is actually quite conservative, because in many cases, when the police do not need to use high-cost solutions such as diatom testing, they will not use them easily.
However, the main reason for the low usage rate of diatom testing in forensic drowning diagnosis is that there still needs to be a corresponding diatom library for comparison. This is similar to DNA, but different from DNA, the diatoms in a place are
It hasn't been around that long, and DNA testing of water bodies across the country is expensive.
However, the Taihe River working group has been formed. In view of the extremely high population density living on both sides of the Taihe River, systematic diatom testing in the Taihe River Basin and keeping files will naturally be very helpful for the detection of subsequent similar drowning cases.
Benefits.
??????55.??????
Although the single cost of doing this is large, once the diatom library is built, the overall cost will be small.
In the past, a single prefecture-level city or county probably did not have such motivation. Because the corpses that floated to the local area were probably not the local source of the corpses, so diatom testing in the local watershed could only be carried out.
The cities downstream can’t help themselves, but they can’t help themselves.
Even a provincial department is too lazy to do this kind of thing. It is not just a matter of cost-effectiveness, there are always more important things to do, and things like databases are always insufficient and cannot reflect value.
Except for frontline personnel.
Fang Gang didn't expect that Jiang Yuan's first order would be so expensive, but he had already agreed, so he could only grit his teeth and said: "We will organize people to carry out water collection and inspection work as soon as possible. However, do you want to
Let’s try other methods first.”
Samples are taken every 50 meters, 20 times for one kilometer, 40 times for the opposite side, and 800 times for 20 kilometers. After all the calculations, the funds for a Mercedes-Benz are spent.
Huang Qiangmin interjected and said: "The work of diatom inspection is long-term. No matter whether this case can be used or not, it will be useful in the future. Now that Qingshi City has joined our Taihe working group,
, then let’s get this project started.”
"Um...Okay." Fang Gang nodded again, the thought of solving the case overriding everything else.
Jiang Yuan saw this and said: "Judging from the photos of the corpse, the deceased should have died within three days. We will make a judgment after seeing the corpse at the specific time. So, generally speaking, this is still an active case, and it can be determined based on the hydrological conditions."
Judgment. The severed legs of the corpse are no longer there, which is good news. When the legs are found, they may be used as a basis for judgment..."
As soon as Jiang Yuan finished speaking, the rubber boat that had just sailed out returned, and the police on the boat shouted loudly:
"leg!"
Several people hurried forward and carried down the package wrapped in a rice dumpling shape.
The outer wrapping of the rice dumpling is cut open a little, and the human tissue inside can be seen.
It has deteriorated, but not much.
It exudes a smell familiar to forensic medicine.
"I'll take it back to have a look." Jiang Yuan did not open the scene, so he asked someone to send the legs away first, and then he inspected the scene again before moving to the morgue.
…
The morgue in Qingshi City.
It has almost a uniform taste across the country, slightly bland.
Six large pieces of corpse tissue were laid out one after another. They were all a bit too bloated, but not to the extent of the Hulk.
Fang Gang came over with several leaders of the criminal police detachment, which was a relatively rare sign of attention, and watched Jiang Yuan dissecting the body.
The corpse also waited for most of the day, so that Jiang Yuan would not have to come over and have to do a second dissection.
However, half a day is not too long. The forensic doctors brought the body back and made some preparations. This was the time it took.
Jiang Yuan arrived at the scene, and the preparations had already been completed. He put on his clothes, checked, and got started.
After a few routine cuts, Jiang Yuan turned his attention to the separated parts of the corpse.
"The person who dismembered the corpse is not very skilled. He cut a lot of knives and changed the tools in the process. He should have changed several types. Let's count them." Jiang Yuan said and started to count.
The forensic assistant nearby quickly took notes.
After a while, Jiang Yuan counted the number to 87.
"At least 87 knives were used." Jiang Yuan breathed a sigh of relief and said: "I changed more than five kinds of tools, including sharp knives, Chinese kitchen knives, scissors, serrated knives, and Japanese chef's knives... Well...
, are all kitchen utensils.”
The result Jiang Yuan said was not surprising.
Although it sounds terrifying, in the eyes of the criminal police, it is just a simple dismemberment.
"The knives are all broken. Let's do some inspections for trace evidence. Maybe we can find the tool manufacturer or something." Jiang Yuan said to the forensic doctor from Qingshi City next to him, then straightened the head of the corpse and thought for a while.
, said: "Let me draw another portrait of him."
The corpse was already a little enlarged. The head looked like it had been beaten and swollen, and the color was not normal. In addition, the head had obviously been hit with a blunt object. The nose bones were broken, the teeth were missing, and the lips were broken.
His ears are missing, his brow bone is fractured, his eye sockets and forehead are also sunken, probably from being beaten with a knife handle or something like that. From a living perspective, his face is actually disfigured.
But dead people don't care about this.
Forensic sketch LV6, not to mention such a small flaw.
