National Forensic Doctor

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 corpse 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, which are annoying.

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

"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 new paint on it, 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 refinished with several layers of paint. We will take several layers of paint. Then, we will 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 nearby 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 produced in the trace evidence laboratory of the provincial department. The newly purchased fluorescence analyzer has 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 he 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 roadside. 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 happened to not do any detailed treatment and just applied a layer of paint and that was it?"

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 crushed ores, which you can see when you go to the site.”

Then came the third question. Jiang Yuan said slowly: "The Xingzi Valley Copper Mine is the end point and does not lead to other places. Therefore, when Tan Yong goes to the Xingzi Valley Copper Mine, it 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 said "yes" and asked, "Then why do you think Apricot Valley is the place where the corpse is buried?"

"The ore particles in Exhibit 3 were obtained from the right rear door, and their origin is similar to that of Exhibit 1. The plant fibers in Exhibit 4 are consistent with the plants in Apricot Valley. They can also be used as indirect evidence to prove that Tan Yong He went to Apricot Valley many times. In addition, these pieces of evidence all appeared three years ago. Other particles found on the car came from outside Changyang City, or from the construction site where Tan Yong worked, which could be used as a burial site. The sex is small." Jiang Yuan spoke slowly.

When he was halfway through speaking, Liu Jinghui actually agreed.

The burial place must be a place visited many times. This was something he had already determined. In addition, the Xingzi Valley Copper Mine was originally within the scope of his judgment. It was difficult to say how much of his previous questioning was intended to make things difficult for Jiang Yuan.

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

It wasn't until there was a buzzing voice in the conference room that Liu Jinghui raised his head and said, "Okay, the goal of today's meeting will be modified to focus on attacking the Xingzi Valley Copper Mine. Gao Gao, can you make arrangements?"

Gao Qiang, the third-level senior police sergeant who also came with him, has been keeping quiet these days. However, being invited by Liu Jinghui, he didn't have any trouble. After coughing twice, he stood up and said: "Then let's divide into several groups first..."
