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 mean?"

"Hmm... Now, it seems like a simple dismemberment case." Jiang Yuan lowered his head and scrolled through his PAD, quickly flipping 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, it was a dismemberment case. Even though the body was not dismembered much, it was still dismembered. Giving it a LV3 was a sign of respect for such cases.

"That's good." Huang Qiangmin breathed a sigh of relief. He occasionally heard Jiang Yuan mention LV1, LV3, and now he basically understood their meaning. He even thought that this classification method was good, as it made it easy to understand the situation and give clear guidance for the negotiation.

Otherwise, if you just say it is difficult, very difficult, or not easy, who knows which one is really difficult.

Jiang Yuan nodded slightly: "It's not difficult. According to our normal process, it is likely that we can do it, but it is also possible that we can't do it. If we can't do it, it will be difficult."

If you can complete the task according to the script, it is not a difficult task.

But from another perspective, people and teams who can carry out tasks according to the script are scarce. For example, out of 150 points in the college entrance examination mathematics, 90 points are for questions that can be read according to the script, and among the college entrance examination candidates every year, less than 60% can reach this level.

Therefore, most people in this world do not even have the ability to follow a script. The stupid people in the workplace, the stupid drivers on the road, and the stupid comments on the Internet are all examples of low-level sliding.

"Is Political Commissar Huang whispering something to our Captain Jiang?"

Fang Gang, the captain 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. The support on your side must be guaranteed. Otherwise, let's not talk about whether the case can be solved or not. The case will be easily dragged on." Almost none of what Huang Qiangmin said was true, but it is true that the police can lie when investigating a case.

Fang Gang's face turned serious, thinking, you just collected two years of membership fees, and you're already talking about the difficulty...

Fang Gang said: "We can definitely guarantee the support we should provide, but our funding is limited. It is impossible to say that it is endless..."

"Mr. Fang, I didn't mean to ask you to pay more." Huang Qiangmin stopped Fang Gang and waved his hand, saying, "I just want you to ensure the funds for handling the case. Did you watch the news broadcast a few days ago?"

"I took a look, and when I saw Jiang Yuan's face, I pointed it out to my family."

"Right. Jiang Yuan's reputation is really not to be underestimated." Huang Qiangmin's expression changed when he said this: "So, this is also a kind of guarantee. Where else can you find a criminal investigation expert like Jiang Yuan?"

In the past, Huang Qiangmin would not say this. He would say fingerprint expert or forensic expert, but now, he just blurts out the word "criminal investigation expert".

Everyone present, especially the criminal police from the Qingshi City Criminal Investigation Detachment, accepted it naturally.

Fang Gang nodded with admiration and relief on his face: "If Jiang Yuan thinks it is necessary, we will cooperate with you without hesitation."

If a criminal investigation expert is considered a weapon, then Jiang Yuan's weapon is already a famous weapon on the level of the Green Dragon Crescent Blade. If you can use it, why be stingy?

"Let's collect water along the upper reaches. Every 50 meters, for 20 kilometers. Send the collected 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. Tell them that I have a project here, similar to establishing a 20-kilometer-long diatom lineage research project 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 few cities, the system has basically been established.

As for drowned bodies, using diatoms to determine where the body entered the water is still very effective. It is not effective for every body, but at least 30% of the bodies can be effective.

This number is actually still conservative, because in many cases, the police will not easily use high-consumption options such as diatom testing when they do not need them.

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. However, unlike DNA, the diatoms in one place do not exist for that long, and it is expensive to conduct DNA testing on water bodies across the country.

However, the Taihe River Working Group has been formed. Given the extremely high population density on both sides of the Taihe River, conducting systematic diatom testing in the Taihe River Basin and keeping records will naturally be extremely beneficial to the subsequent detection of similar drowning cases.

Although the one-time cost of doing this is high, once the diatom bank 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 drifted to the local area were probably not from the local area, so diatom detection in the local watershed could only help the downstream cities, not the local area.

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 the frontline personnel.

Fang Gang didn't expect that the first order Jiang Yuan issued would be so costly, but he had already agreed, so he could only grit his teeth and responded: "We will organize personnel to collect water and conduct inspections as soon as possible. However, how about trying other methods first."

Sampling is done every 50 meters, which means 20 times per kilometer, 40 times on the other side, and 20 times for 800 kilometers. If you add up all the numbers, it's like the cost of a Mercedes-Benz.

Huang Qiangmin interjected, "The work of diatom inspection is long-term. Regardless of whether it can be used in this case, it will always be useful in the future. Since Qingshi City has joined our Taihe working group, let's get this project started."

"Well... okay." Fang Gang nodded again. The desire to solve the case overwhelmed everything else.

Seeing this, Jiang Yuan said, "Based on the photos of the body, the deceased should have died within three days. The specific time will be determined after we see the body. So, overall, this is still a current case, and we can make a judgment based on the hydrological conditions. The legs of the body are gone, which is actually good news. When the legs are found, maybe we can use it as a basis for judgment..."

As soon as Jiang Yuan finished speaking, the rubber boat that had just sailed out returned, and the police officer on the boat shouted loudly:

"leg!"

Several people hurried forward and worked together to lift down the package that was wrapped like a rice dumpling.

If you cut a little bit of the wrapping outside the zongzi, you can see the human tissue inside.

It's spoiled, but not much.

It exudes a familiar forensic smell.

"I'll take it back to have a look." Jiang Yuan did not open the door on the spot. He asked someone to send the leg away first. He inspected the scene again before going to the morgue.

……

The morgue in Qingshi City.

The taste is almost the same across the country, slightly lighter.

The six large pieces of corpse tissue were arranged one by one, and they all had the problem of being too swollen, but not to the extent of the Hulk.

Fang Gang came with several leaders of the Criminal Police Brigade. This was a rare display of importance, and they watched Jiang Yuan perform an autopsy.

The body had to wait for most of the day to avoid a second autopsy if Jiang Yuan came.

However, half a day is not too long. The forensic doctors will bring the body back and make some preparations, which will only take this much time.

When Jiang Yuan arrived, the preparations had already been completed. He put on his clothes, checked himself, and started to work.

After a few routine incisions, Jiang Yuan turned his attention to the separated parts of the body.

"The person who dismembered the body was not very skilled. He used many cuts and changed tools in the middle. He should have changed several types. Let's count them." Jiang Yuan said and started counting.

The forensic assistant next to him hurriedly took notes.

After a while, Jiang Yuan counted to 87.

"At least 87 knives were used." Jiang Yuan sighed and said, "I changed more than five kinds of tools, including sharp knives, Chinese kitchen knives, scissors, serrated knives, and Japanese chef knives... Yes, they are all kitchen utensils."

The result Jiang Yuan said was not surprising.

Although it sounds horrifying, to the criminal police, it is nothing more than a simple dismemberment.

"The knives are all broken, so let's do some trace evidence checks. Maybe we can find the tool manufacturer or something." Jiang Yuan said to the Qingshi City forensic doctor next to him, then straightened the head of the corpse, thought for a moment, and said, "I'll draw another portrait of him."

The body was a bit bloated, and the head looked like it had been beaten up, and the color was not normal. In addition, the head was obviously hit with a blunt object, with a broken nose, lost teeth, missing lips and ears, a fractured eyebrow, and sunken eye sockets and forehead. It was probably hit with something like a knife handle. From the perspective of a living person, the face was actually disfigured.

But the dead don't care about that.

Forensic Sketching Level 6 doesn’t even bother with such a minor flaw.
