Chapter 56: In Summary

Large conference room.

The air conditioner was blowing, and the force was so great that the spider plants in the corner were swaying.

The spider plants looked unhurried, stretching their bodies, looking graceful, like Zhao Feiyan finding a job in the world of heaven, and like Pan Jinlian finding the first bucket of gold in life in the live broadcast room... The wind direction changed slightly, the branches and leaves of the spider plants were less affected by the wind, and their posture became hard and strong, just like Pan An showing off in the city, and like Wang Xizhi drunk and shouting on the microphone.

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

Liu Jinghui turned directly to the last page, and saw a paragraph written on the last page: In summary, there is reason to suspect that the Apricot Valley Copper Mine 25 kilometers west of Changyang City is the place where the corpse is hidden.

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

The Apricot Valley mine cave was within the verification range Liu Jinghui had drawn, and Liu Jinghui had a deep impression of it.

In fact, in today's meeting, Liu Jinghui planned to arrange for people to go to the Apricot Valley Copper Mine. He was confident that as long as there was another round of verification, he would be able to narrow the verification range from 25 to within 10, and then, at most by the third round of verification, he would be able to narrow the range to within three, at most five. By that time, using police dogs or other technical means would have a great chance of finding Tan Yong's burial site.

This was a brain-storming advancement, a classic demonstration of solving a case with meticulous thinking.

However...

Liu Jinghui stared at the thick report in his hand.

Those cold numbers, those hard charts, were like cheat sheets used for cheating, making people feel bored.

When did the elegant detective disappear, and all these silly fools took his place!

"Tell me about your 'in summary'," Liu Jinghui shook 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 he had just received the report, so he said excitedly: "I conducted a thorough inspection of the suspect Tan Yong's car and reached the following conclusions..."

"The suspect's car is that Pajero, right? Wasn't it checked? A second inspection is easily contaminated by the first inspection," Liu Jinghui interrupted Jiang Yuan.

"I mainly collected trace evidence, which are basically locations that are not or are not easily contaminated," Jiang Yuan said.

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

There were nearly a hundred people sitting in the conference room, all stretching their necks to listen at this time, and some naturally followed with laughter.

Jiang Yuan didn't laugh, looked down at Liu Jinghui's big back head center point calmly, 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 rolled over gravel on the side of the road, and the gravel hit the fender, so trace amounts of stone powder were embedded in the paint surface. When the suspect handled it later, he brushed new paint on it, but instead protected the physical evidence."

Liu Jinghui was stunned and asked: "Third layer of paint?"

"Yes, I found that Tan Yong's Pajero had many local touch-up paint locations, so I decided to take off the paint surface with touch-up paint layer by layer. Including the surface paint, middle layer, bottom layer paint, putty... Some cars will be painted with several layers, and we will take as many layers as it is painted. Then, use a microscope to find trace evidence layer by layer."

Liu Jinghui felt a headache 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 crime scene investigation asked: "Must use a microscope? The workload is too big, can you use tape to stick it once?"

"Ordinary tape won't work, because what we are looking for is trace evidence, many of which are in milligrams, so the glue of the tape will cause pollution, and in the end, the evidence found may not be usable."

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

Jiang Yuan saw that there were no other questions, "The third page is the detailed explanation of this evidence. Its content is consistent with the ore composition record of Apricot Valley Copper Mine. The trace evidence was done in the Provincial Department's trace evidence laboratory. The newly purchased fluorescence analyzer has a very low demand for the amount of samples tested..."

Jiang Yuan was also the first time to collect trace evidence after obtaining the system's skills, so all processes were done quite meticulously.

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

After thinking for a few seconds, Liu Jinghui gestured and said: "So, your guess is that when Tan Yong drove past Apricot Valley Copper Mine, the wheels rolled over the gravel on the side of the road, and the splashing gravel was actually ore, which hit the front fender of his car and happened to be embedded in the paint surface, and Tan Yong didn't do detailed processing when repairing the car, just painted a layer of paint?"

Jiang Yuan was silent for a while.

The conference room with more than a hundred people was unusually quiet for a while.

At this time, Jiang Yuan organized his language and said: "Tan Yong's car is old, and he often runs on construction sites, so he finds very familiar repair shops to repair the car, and many places are handled very roughly."

Then, Jiang Yuan answered the second question and said: "On the side of the road of Apricot Valley Copper Mine, there is gravel everywhere, all left by the trucks that pulled ore before. The larger ones should have been cleaned up, but the remaining fine gravel is still very much, and you can see it when you go to the scene."

Then, it was the third question, Jiang Yuan said slowly: "Apricot Valley Copper Mine is the terminal and does not lead to other places. So, Tan Yong going to Apricot Valley Copper Mine should be the destination."

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

Liu Jinghui gave an "Okay" and asked: "Then why do you think Apricot Valley is the place where the corpse is buried?"

"The ore particles of evidence 3 were taken from the right rear door, and the source is similar to evidence 1. The plant fibers of evidence 4 are consistent with the plants in Apricot Valley. They can also be used as indirect evidence to show that Tan Yong went to Apricot Valley many times. In addition, these pieces of evidence appeared more than three years ago. Other micro-particles found on the car either came from outside Changyang City or from the construction site where Tan Yong worked, and the possibility of being a burial point is relatively small," Jiang Yuan slowed down his speech.

When he said half of it, Liu Jinghui actually recognized it.

The burial site must be a place visited many times, which is the key point he had determined long ago. Coupled with the fact that Apricot Valley Copper Mine was originally within his judgment range, it is hard to say how much of his questioning was to make things difficult for Jiang Yuan.

However, solving the case is important after all, Liu Jinghui had to lower his head to read Jiang Yuan's report, which took a considerable amount of time.

Until there was a buzzing small talk in the conference room, Liu Jinghui raised his head and said: "Alright, let's modify the goal of today's meeting and focus on Apricot Valley Copper Mine. Director Gao, can you arrange it?"

Gao Qiang, the third-level senior police officer who came with him, had been invisible these days. However, being invited by Liu Jinghui, he didn't have any stumbling blocks, coughed twice, and stood up directly and said: "Then let's divide into a few groups first..." ===== CHAPTER 57 =====
