Chapter 56 In Summary

Large conference room.

The air conditioner whirred, blowing so hard that the spider plants in the corner shook.

The Chlorophytum looks unhurried. It stretches its figure and looks graceful, like Zhao Feiyan who has found a job in heaven and earth, and like Pan Jinlian who has found the second pot of gold in her life in the live broadcast room... The wind direction has changed slightly, The branches and leaves of Chlorophytum are less exposed to the wind, and their posture has become hard and strong, just like Pan An swaggering through the market, or Wang Xizhi drunkenly shouting wheat.

Liu Jinghui took the report from Yu Wenshu's hand, only to see that it was full of dense numbers and charts.

Liu Jinghui turned to the end and saw a paragraph written on the last page: In summary, there are reasons to suspect that the Xingzi Valley Copper Mine, 25 kilometers west of Changyang City, is the location where the body is hidden.

At that moment, Liu Jinghui seemed to suddenly become a martial arts master, and his temples bulged and hurt.

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

In fact, during today's meeting, Liu Jinghui planned to arrange for people to go to the Xingzi Valley Copper Mine. He is confident that with one more round of verification, he can narrow the scope of verification from 25 to less than 10, and then, by the third round of verification at most, he can narrow the scope to less than three, and at most five. By that time, using police dogs or other technical means, there will be a great chance of finding the burial place of Tan Yong.

This is an intellectual storm-like advancement and a classic example of solving a case with rigorous thinking.

However……

Liu Jinghui stared at the thick report in his hand.

Those cold numbers and those rigid charts are like cheat sheets for cheating, which is annoying.

When did the elegant detective disappear, only to be replaced by these stupid idiots!

"Tell me about your 'summary'." Liu Jinghui shook off the report and had to look up at Jiang Yuan.

Jiang Yuan didn't care about Liu Jinghui's attitude. He had been busy for so many days and only got the report. He said excitedly: "I did a thorough inspection of the suspect Tan Yong's vehicle and came to the following conclusion..."

"The suspect's car is probably the Pajero. Hasn't it been inspected? The second inspection may be easily contaminated by the first inspection." Liu Jinghui interrupted Jiang Yuan.

"I mainly collected trace evidence, which are basically from locations that will not or are not easily contaminated." Jiang Yuandao.

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

There were nearly a hundred people sitting in the conference room. They all craned their necks to listen, and some naturally laughed.

Jiang Yuan did not smile. He calmly looked down at the center of Liu Jinghui's back and said, "The first piece of evidence was taken from the third layer of paint on the left front fender of the suspect's vehicle. It is guessed that the vehicle ran over the road. When the gravel hit the fender, a trace amount of stone powder was embedded in the paint surface. When the suspect subsequently processed it, he painted it with new paint, which protected the evidence. "

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

"Yes, I found that the Pajero owned by the suspect Tan Yong had a lot of partially repaired paint. Therefore, I decided to remove the repaired paint in layers. Including the surface paint, the middle layer, the base paint, putty... ...Some cars will be repainted with multiple layers of paint. We will take several layers of paint and then use a microscope to look for trace evidence layer by layer. "

Liu Jinghui felt dizzy after hearing this, and the first thought that came to his mind was: This is too ungraceful.

At this time, a leader next to him who knew something about on-site investigation asked: "Do you have to use a microscope? That would be too much work. Can I just tape it up again?"

"Ordinary tape will not work, because the evidence you are looking for is trace amounts, and many of them are measured in milligrams. Therefore, the glue of the tape will cause contamination. In the end, the evidence found will probably not be used."

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

Jiang Yuanyuan 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 made in the trace evidence laboratory of the provincial department. The newly purchased fluorescence analyzer has a very low demand for the amount of sample to be tested..."

Jiang Yuan also collected trace evidence for the first time after acquiring systematic skills, so all processes were done very carefully.

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

After thinking for a few seconds, Liu Jinghui stretched out his hand to make famous signs and said, "So, your guess is that when Tan Yong drove past the Xingzi Valley Copper Mine, his wheels hit the gravel on the side of the road. The gravel that flew up was actually... The ore hit the front fender of his car and happened to be embedded in the paint. Moreover, when Tan Yong repaired the car, he just applied a layer of paint without doing any detailed treatment? "

Jiang Yuan was silent for a while.

The conference room with more than a hundred people seemed 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 construction sites, so he always goes to a very familiar car repair shop to repair the car, and the repairs in many places are very rough. "

Then, Jiang Yuan answered the second question and said: "There are gravels everywhere on the roadside of Xingzigu Copper Mine, which are all left by the trucks that used to pull the ore. The larger ones should have been cleaned up, leaving There are still a lot of finely divided ores, which you can see when you go to the site.”

Then, the third question, Jiang Yuan said slowly: "Xingzigu Copper Mine is the end point, and it does not lead to other places. Therefore, Tan Yong went to Xingzigu Copper Mine, which should be the destination."

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

Liu Jinghui said "yeah" and asked: "Then why do you think Xingzigu is the place where the body was buried?"

"The ore particles in Exhibit 3 were taken from the right rear door, and the source is similar to Exhibit 1. The plant fiber in Exhibit 4 is consistent with the plants in Xingzigu. They can also be used as indirect evidence to show that Tan Yong went to Xingzigu many times. In addition, these pieces of evidence appeared three years ago. The other particles found in the car may come from outside Changyang City, or from the construction site where Tan Yong worked, and the possibility of using them as the burial site is relatively small." Jiang Yuan spoke slowly.

When he was halfway through, Liu Jinghui actually agreed.

The burial site must be a place that he had visited many times. This is the key point he had determined long ago. In addition, the Xingzigu Copper Mine was originally within his judgment range, so it was hard to say how much of his questioning was intended to make things difficult for Jiang Yuan.

However, solving the case was the most important thing after all, so Liu Jinghui had to lower his head to read Jiang Yuan's report, which took quite a long time.

It was not until the buzzing of small voices in the conference room that Liu Jinghui raised his head and said, "Okay, let's revise the goal of today's meeting and focus on the Xingzigu Copper Mine. Gao Chu, can you make arrangements?"

The third-level senior police officer Gao Qiang who came with him has been keeping a low profile these days. However, he was invited by Liu Jinghui, so he didn't hesitate. He coughed twice and stood up and said, "Then let's divide into several groups first..."
