Chapter 1253 Decent People

"Didn't you pick a suitable case?" Wu Zhisu was shocked.

He had been considering various possibilities along the way, and this possibility was the worst.

Fortunately, Huang Qiangmin shook his head slightly and said, "It's our Jiang Yuan. He actually dug up a high-ranking corruption case for you, the 1011 floating corpse case. Do you remember it?"

"Yes, of course!" Wu Zhisu became happy all of a sudden. This was a long-standing drowning case, and he would take advantage of it if he could.

Even though Jiang Yuan's Taihe Working Group investigates various drowning cases day after day, ordinary police stations are all annoyed when they really encounter such cases, otherwise how could they be willing to pay money to the Taihe Working Group.

Wu Zhisu was the captain of the Jianjiang City Criminal Police Detachment. Jianjiang City was a prefecture-level city, on the same level as Qinghe City and one level higher than Ningtai County. But even if it was a prefecture-level city Criminal Police Detachment, he could not necessarily solve a drowning case in three to five months by organizing a special task force. Not to mention the backlog of drowning cases, in the past, solving such cases would start with a second-class merit.

However, it is very difficult to make an appointment with an expert like Jiang Yuan. It was only because Jianjiang City is next to Ningtai County and they have interactions with each other that Wu Zhisu was able to sense Jiang Yuan's presence a few times.

However, precisely because I have experienced it, I can't stop doing it.

Solving a case is actually like doing exercises. Cases are like math problems. Most of the questions are multiple-choice questions. At most, there will be a fill-in-the-blank question. For an ordinary criminal police detachment, throughout the year, they can only solve a short-answer question, or a slightly more difficult short-answer question, and that's the end of their task.

You can do any way you like for ordinary questions. Many times what we are discussing is actually time and cost-effectiveness. We want to finish it as quickly as possible with the least possible investment. In the police force, ordinary cases require the least possible number of people and they just need to be completed as quickly as possible. There are certain requirements for the accuracy rate, but it won't be too outrageous.

The core of the problem is not the time, but the ability to complete it. Setting up a special task force is equivalent to a collective discussion. But the real problem is that even collective discussions cannot solve it. The more difficult backlog murder cases may be problems that even teachers in ordinary schools cannot complete.

Wu Zhisu saw that Jiang Yuan had chosen the 1011 floating corpse case, and immediately tapped his head and said, "I remember that a large team was in charge of this case, and later more than a dozen people were added. The state of the corpse was too bad, but there were some relics in the pockets of the corpse. We started from the relics and tried to find the buyer, but to no avail..."

Huang Qiangmin listened casually and asked, "Has it been restarted?"

"No. There are no new clues, so we can't restart it." Wu Zhisu said, glancing at Huang Qiangmin, and said, "We have already discussed it, and you can't raise the price at the last minute. Whatever case we win, it's the case. We are all respectable people!"

"A high-level corruption case!" Huang Qiangmin emphasized.

"It's rotten, so what floating corpse wouldn't rot? Moreover, we had another judgment about the wounds in this case. That...forensic doctor, can you tell me about it?" Wu Zhisu quickly started discussing the case to avoid telling Huang Qiangmin.

Wen Youchuan stepped forward and said, "We found a crescent-shaped blunt force wound on the head of the corpse. We initially determined that the murder weapon was a hammer."

He said as he hurriedly searched for photos in the files. These were important images, and they were all printed out as physical photos.

While Jiang Yuan was looking at the photos, Huang Qiangmin said to Wu Zhisu, "It's fine for normal decay, but this high-level decay case is very difficult even if we determine the location of the drowning."

"I understand, I understand, but what we have agreed on cannot be changed! Decent man." Wu Zhisu reached out and held Huang Qiangmin's hand.

"It's been 8 years!" Huang Qiangmin emphasized again.

Wu Zhisu hesitated for a moment and said, "Can the diatoms from eight years ago still match the ones now?"

"If it matches, then it matches. If it doesn't match, then it doesn't match. This is not the same as DNA." Huang Qiangmin said, turning around and calling Jiang Yuan, "Can you explain it to Wu Zhi?"

Jiang Yuan said, "In a water system, there are usually highly dynamic areas and stable areas. Highly dynamic waters are like estuaries and sewage outlets. The diatom structures in these areas are updated very quickly, and the database usually needs to be updated once a year or so. We haven't done that yet. Stable areas are like slow-flowing areas and deep pools. If there is no triggering event, they may not change in ten or eight years. But just like what Political Commissar Huang said, if they can be compared, it proves that there has been no change. If they haven't been compared, it can't be ruled out."

Wu Zhisu understood instantly and said "good" repeatedly, "This technology is updated well, so theoretically, if it is successful, it can also be used for cases that have been pending for more than ten years?"

"Assuming the match is correct, it means that the diatom community in the area where the water fell has not changed in the past decade. However, generally speaking, 10 years is a threshold, because the ecosystem of the diatom community has a stable period of about 20 years, plus the impact of human activities... Sediment diatoms can be considered, but that does not fall within the scope of our database..." Jiang Yuan gave a brief introduction.

"That's enough, that's enough." Wu Zhisu didn't actually think about things that far ahead. He would be happy as long as he was sure that he could solve a long-standing case.

Huang Qiangmin looked at Wu Zhisu with a smile and said, "Gao Fu, 8 years, right?"

"A respectable man!" Wu Zhisu repeated.

"Okay, okay. What we have agreed on cannot be changed! Decent man!" Huang Qiangmin shook hands with him and repeated it.

Wu Zhisu originally thought that he would bleed again, but when he saw that Huang Qiangmin really wanted to be a respectable person, he was delighted and quickly looked at Jiang Yuan and asked, "How is it? The blunt force wound?"

Jiang Yuan clicked on the photo and agreed, "It was definitely caused by a hammer. However, there are diatoms in the deceased's bone marrow, so he must have been hit by the hammer but didn't die, and eventually drowned. The hammer wasn't found, right?"

"No. The shape of this hammer is too ordinary. Our investigation at the time was mainly focused on the clothes wrapped around the deceased, especially a button. We traced it to the tailor shop below, but still found nothing." Wu Zhisu was not the direct person in charge, and it was still a bit regretful to say that, which showed that he was indeed very concerned about this case.

Unfortunately, paying attention is helpful for handling cases, but it is not absolute.

Jiang Yuan nodded, pushed the photos and files aside, and said, "Then let's investigate based on diatoms first. The place where the body fell into the water is Fanjia Village upstream of Ningtai County. Do you have any impression of it?"

Wu Zhisu thought about it seriously, shook his head slowly, and said, "I don't remember. Wait a minute, I'll call Zhang Yan from the First Brigade. He's out on a field trip today. If I had known it was this case, I would have called him over."

He said as he took out his cell phone to make a call.

After the call was connected, Wu Zhisu listened to Zhang Yan and Jiang Yuan talking for a while before he suddenly realized, "Wait, have you all determined where the deceased fell into the water?"

Jiang Yuan nodded: "Because it matched, we can check the database and find out where the same diatom colony is from, and thus determine the place where the deceased fell into the water."

"Okay, okay..." Wu Zhisu was still friendly to Jiang Yuan. He turned to look at Huang Qiangmin with murderous intent in his eyes: "Isn't this diatom work done?"

"A decent person!" Huang Qiangmin reminded Wu Zhisu.

Wu Zhi angrily pointed at Huang Qiangmin: "You old..."

"Old Wu, can we solve the case if we know the place where he fell into the water?" Huang Qiangmin pried Wu Zhisu's hand off.

As expected, Wu Zhisu hesitated.

Indeed, knowing where the person fell into the water is certainly an additional clue, but it does not necessarily mean that the case can be solved.

Huang Qiangmin said softly, "We Jiang Yuan went all the way to the end. Now that we know the place where the person fell into the water, we will look for clues near the place where the person fell into the water. If we can confirm the identity of the deceased, that would be the best. If that doesn't work, we Jiang Yuan is good at forensic anthropology. If that doesn't work, we still have skull reconstruction. We can directly restore the face of the deceased before his death. Facial recognition or handing out flyers will do. This is more than double insurance and triple insurance. Don't you buy insurance for free? Don't you want this insurance?"

"Hmm..." Wu Zhisu admitted that he was convinced, and he only said in a stammering voice: "Then let's just do the skull reconstruction technique."

"Three months." Huang Qiangmin glanced at Wu Zhisu and said calmly, "If we do this, the Taihe Working Group won't be able to solve four cases in a year."

Wu Zhisu coughed twice and said, "No matter what happens next, let's just follow the previous steps."

"Yeah." Huang Qiangmin nodded and handed a cigarette to Wu Zhisu.

Wu Zhisu took it, took out his lighter and lit it for Huang Qiangmin first.

On the other side, Wang Chuanxing distributed the newly collected information to the members of the backlog case task force, and everyone got busy.

After Wu Zhisu finished smoking a cigarette, he completely relaxed. He took a sip of tea and prepared to have a good chat with Huang Qiangmin.

At this time, Tang Jia picked up the information and said, "I have a report from a villager in Fanjia Village. His wife had been missing for five years, so he called the police and asked to dissolve the marriage. If we calculate the time, his wife disappeared eight years ago."

"Let me see!" Wu Zhisu suddenly became excited.

Huang Qiangmin took the last puff of his cigarette and whispered from behind: "A respectable man!"
