Chapter 1010 Small flaws
Huang Qiangmin used his superb skills to temporarily get rid of the blockade of several Qingshi City criminal police, and came to Jiang Yuan and asked: "What do you say?"
"Well... Now it seems that it is a simple dismemberment case." Jiang Yuan lowered his head and swiped his PAD, quickly flipping through the photos of the body, and then said: "There should be quite a lot of clues."
"How difficult is it?"
"Weak LV3." After all, it is a dismemberment case. Although the "dismemberment" is not much, it is still broken. Giving it a LV3 is a respect for such cases.
"That's not bad." Huang Qiangmin breathed a sigh of relief. He occasionally heard expressions like LV1 and LV3 from Jiang Yuan, and now he basically understood their meaning. He even thought that this classification method was good, and he understood the situation at once, and the guidance for the negotiation was clear.
Otherwise, just saying difficult, very difficult, and difficult to deal with, who knows which one is really difficult.
Jiang Yuan nodded slightly: "It's not difficult. According to our normal process, it is likely to be done, but it is also possible that it cannot be done. If it cannot be done, the difficulty is high."
If you can complete the task according to the script, it is not a very difficult task.
But from another perspective, people and teams who can perform tasks according to the script are scarce. For example, out of 150 points in the college entrance examination mathematics, 90 points are questions that are read from the script, and among the college entrance examination population every year, less than 60% can reach this level.
So, most people in this world don't even have the ability to read from the script. Those stupid people in the unit, 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 head of the criminal police detachment of Qingshi Municipal Bureau, came over with a smile.
"Your case is too difficult. Jiang Yuan discussed with me how to explain the situation to you. You must ensure support on your side. Otherwise, let's not talk about whether the case can be solved or not. The case will be easily dragged on." Huang Qiangmin's words were basically not true, but it is true that the police can lie when handling cases.
Fang Gang's face turned serious, thinking, you just collected two years of membership fees, and you're talking about difficulty...
Fang Gang said: "The support that should be given can definitely be guaranteed, but our funds are also limited, it's impossible to say that it's endless..."
"Old Fang. I didn't mean to ask you to pay more." Huang Qiangmin stopped Fang Gang and waved his hand and said: "I just want you to guarantee the funds for handling the case. Have you watched the news broadcast a few days ago?"
"I watched it. When I saw Jiang Yuan's face, I pointed it out to my family."
"Right. Our Jiang Yuan's reputation is really not covered." Huang Qiangmin's expression changed when he said this: "So, this is also a guarantee. Where can you find a criminal investigation expert like our Jiang Yuan?"
In the past, Huang Qiangmin would not say this. He would say fingerprint expert, forensic expert, but now, he said the word "criminal investigation expert" loudly.
And everyone present, especially the criminal police of the Qingshi City Criminal Investigation Detachment, naturally accepted it.
Fang Gang nodded with admiration and relief: "If Jiang Yuan thinks it is necessary, we will cooperate with him without hesitation."
If criminal investigation experts are regarded as a weapon, then Jiang Yuan's weapon is already a famous weapon at the level of Qinglong Yanyuedao. Why be stingy if you can use it.
"Take water along the upstream. Take 20 kilometers every 50 meters. Send the water samples to the laboratory for diatoms. In addition..." Jiang Yuan turned to Wang Chuanxing and said: "Please ask Professor Su Lei and others to come over and say that I have a project here, which is similar to establishing a 20-kilometer-long diatom spectrum research project in the upper reaches of 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 few cities. However, this system has basically been established.
For drowned bodies, using diatoms to determine the place where the body entered the water is still very effective. Not every body is effective, but at least 30% of the bodies can be effective.
This number is actually conservative, because in many cases, when the police do not need to use high-cost solutions such as diatom testing, they will not easily use it.
However, the main reason why diatom testing is less used in forensic drowning diagnosis is that there must be a corresponding diatom library for comparison, which is similar to DNA, but different from DNA, the existence of diatoms in one place is not that long, and DNA testing of water bodies across the country is expensive.
However, the Taihe Working Group has been formed. Given the extremely high population density on both sides of the Taihe River, it is naturally extremely beneficial to conduct systematic diatom testing in the Taihe River Basin and keep archives, which will be extremely beneficial to the subsequent detection of similar drowning cases.
Although the single cost of doing so 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 corpse that floated to the local area is likely not the local source of the corpse, then the diatom testing of the local basin can only help the downstream cities, not itself.
Even a provincial department is too lazy to do this. It's not just a cost-effectiveness issue. There are always more important things to do, and databases are always insufficient and cannot reflect their value.
Except for front-line 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 Try something else first.”
Samples are taken every 50 meters, 20 times for one kilometer, 40 times for the opposite side, and 20 kilometers equal to 800 times. 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 judge the specific time after seeing the corpse. So, in general, 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 policeman 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's spoiled, but not much.
It smells familiar to forensics.
"I'll take it back and take a look." Jiang Yuan didn't open the scene, so he asked someone to send the legs away first. He surveyed 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 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 do a second dissection.
However, half a day is not too long. The forensic doctors brought the body back and made some preparations. That was the time.
Jiang Yuan arrived at the scene, and the preparations had already been completed. He put on his clothes and checked, and then just 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 next to him 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 body was already a little swollen, and the head looked like it had been beaten and swollen, and the color was not normal. In addition, the head was obviously hit with a blunt object. The bridge of the nose was broken, the teeth were lost, the lips and ears were missing, the brow bone was fractured, and the eye sockets and forehead were also sunken. It was probably beaten with something like the handle of a knife. Yes, from a living perspective, the face is actually disfigured.
But dead people don't care about this.
Forensic sketch LV6, not to mention such a small flaw.
