Chapter 56

Large meeting room.

The air conditioner was whistling, and the spider plants in the corner were blown vigorously and shook.

Chlorophytum looks calm and unhurried. It stretches its body and looks graceful, like Zhao Feiyan found a job in heaven and earth, and like Pan Jinlian found her second pot of gold in the live broadcast room... The wind direction changed slightly, The branches and leaves of Chlorophytum were less exposed to the wind, and their posture became firm and strong, just like Pan An strutting through the market, or like Wang Xizhi shouting wheat while drunk.

Liu Jinghui took the report from Yu Wenshu, but saw that it was full of numbers and diagrams.

Liu Jinghui turned directly to the end, and saw a paragraph on the last page: In summary, there are reasons to suspect that the Xingzigu Copper Mine, 25 kilometers west of Changyang City, is the place where the corpses were hidden.

At that moment, Liu Jinghui seemed to have suddenly become a martial arts master, and his temples were bulging and painful.

The Xingzigu Mine is within the inspection range designated by Liu Jinghui, and Liu Jinghui is quite impressed by it.

In fact, in today's meeting, Liu Jinghui planned to arrange for someone to go to the Xingzigu Copper Mine.He is confident that as long as there is another round of inspections, he can narrow the scope of inspections from 25 to less than 10, and then, at most, by the third round of inspections, he can narrow the scope to three, at most five.At that time, with the use of police dogs or other technical means, there will be a great chance to find the place where Tan Yong's body is buried.

This is an intellectual storm-like advancement, and it is a classic demonstration of solving a case with meticulous thinking.

however……

Liu Jinghui stared at the thick report in his hand.

Those cold numbers and those blunt charts are like cheat sheets for cheating, which makes people feel bored.

When, when the elegant detective disappeared, all these stupid bastards were waiting for him!
"Tell me about your 'summary'." Liu Jinghui shook the report and had to look up at Jiang Yuan.

Jiang Yuan didn't care about Liu Jinghui's attitude. After working for a few days, he finally got the report, and said excitedly, "I did a thorough inspection of the suspect Tan Yong's vehicle, and came to the following conclusions..."

"The suspect's car is the Pajero, right? Hasn't it been inspected? The second inspection is likely to be polluted by the first inspection." Liu Jinghui interrupted Jiang Yuan's words.

"I mainly collected trace amounts of evidence, which are basically places that will not or will not be easily contaminated." Jiang Yuan said.

Liu Jinghui smiled: "What part is so chaste?"

There were nearly a hundred people sitting in the meeting room, and they all stretched their necks to listen, and some naturally laughed.

Jiang Yuan didn't smile, and calmly looked down at the center of Liu Jinghui's big back, and said, "The first piece of evidence was obtained from the third layer of paint on the left front fender of the suspect's vehicle. It is guessed that the vehicle was crushed onto the road." The gravel on the side, the gravel was hit on the fender, and a small amount of stone powder was embedded in the paint surface. When the suspect processed it later, he painted new paint on it, which protected the evidence instead. .”

Liu Jinghui was stunned when he heard that, and asked, "The third layer of paint?"

"Yes, I found that the Pajero of the suspect Tan Yong has a lot of places for partial repainting. Therefore, I decided to remove the paint surface with repainting in layers. Including surface paint, middle layer, primer, putty... …Some cars will touch up several layers of paint, and we will take a few layers of paint. Then, use a microscope to find trace evidence of the paint layer by layer.”

Liu Jinghui's head got dizzy when he heard it, and the first thought that came to his mind was: This is too inelegant.

At this time, a leader next to him who knew a little about on-site inspections asked, "Do I have to use a microscope? The workload is too much. Can I stick it with tape?"

"Ordinary adhesive tape is not good, because what is looking for is trace evidence, many of which are measured in milligrams. Therefore, the glue of the adhesive tape will cause pollution. In the end, the evidence found may not be used anymore."

"This..." The leader next to him felt his scalp go numb.

Jiang Yuan saw that he had no other questions, "The third page is a detailed description of this evidence. Its content is in line with the ore composition records of the Xingzigu Copper Mine. The trace evidence was done in the trace evidence laboratory of the Provincial Department. The newly purchased fluorescence analyzer has a very low demand for the amount of samples to be tested..."

It was also the first time for Jiang Yuan to do the collection of trace physical evidence after acquiring the systematic skills, so all the processes were done in a very meticulous manner.

Liu Jinghui listened to the terms Jiang Yuan said, impatiently, but had to admit that the answers he gave were extremely tempting.

After thinking for a few seconds, Liu Jinghui stretched out his hand and gestured, and said, "So, your guess is that when Tan Yong drove past the Xingzigu Copper Mine, the wheels hit the gravel on the side of the road, and the splashed gravel was actually The ore hit the front fender of his car, and happened to be embedded in the paint surface, and when Tan Yong repaired the car, he just applied a layer of paint without any careful treatment?"

Jiang Yuan was silent for a while.

The conference room with more than [-] people was unusually quiet for a while.

At this time, Jiang Yuan sorted out his words and said: "Tan Yong's car is old, and he often goes to the construction site, so he always finds a familiar car repair shop for car repairs, and the handling of many places is very rough. .”

Then, Jiang Yuan answered the second question, saying: "There are gravels everywhere on the roadside of the Xingzigu Copper Mine, which are left by the trucks that pulled the ore before. The larger pieces should be cleaned up and left behind. There are still a lot of finely crushed ores, which can be seen at the scene.”

Then came the third question, Jiang Yuan said slowly: "Xingzigu Copper Mine is the end point, and it doesn't lead to other places. Therefore, Tan Yong's trip to Xingzigu Copper Mine should be the destination."

Compared with the thick report, Jiang Yuan's simple reasoning made Liu Jinghui a little more comfortable, but only a little.

Liu Jinghui gave an "en" and asked, "Then why do you think Xingzi Valley is the place where the corpses are buried?"

"The ore particles of evidence 3 were taken from the right back door, and the source is similar to that of evidence 1. The plant fibers of evidence 4 are consistent with the plants of Xingzigu. They can also be used as indirect evidence to explain that Tan Yong I have been to Xingzi Valley many times. In addition, these evidences all appeared three years ago. The other particles found on the car either came from outside Changyang City, or the construction site where Tan Yong worked, and they may be used as burial sites Less sexual." Jiang Yuan spoke slowly.

When he was halfway through, Liu Jinghui actually agreed.

The place where the corpse was buried must be a place where he had traveled many times. This was the main point he had determined long ago.Coupled with the fact that the Xingzigu Copper Mine was originally within the scope of his judgment, it was hard to say how much of his questioning just now was to make things difficult for Jiang Yuan.

However, after all, solving the case is the most important thing, Liu Jinghui had to read Jiang Yuan's report with his head down, so it took a long time.

Liu Jinghui didn't raise his head until there was a buzzing sound in the meeting room, and said, "Okay, let's revise the goal of today's meeting, and focus on the Xingzigu Copper Mine. Higher up, can you arrange it?"

Gao Qiang, the third-level senior police sergeant who came with him, has been quiet these days.However, being invited by Liu Jinghui, he didn't stumble, he coughed twice, got up and said, "Then let's divide into several groups first..."
