    Although Brother Ming usually looks cold to everyone, everyone who knows him knows that he is actually a big warm pot, and his interpersonal relationships are much wider than we imagined. We just arrived at 10 o'clock in the morning  After the meeting, at 12 noon, all experimental tools were ready.

    The suspect started dumping the body at the foot of Longtou Mountain. During the dumping process, the weight of the two woven bags had already begun to decrease. This distance would affect the final data of the experiment, so in order to get a more accurate distance, we could only abandon the suspect and go up the mountain.  This section starts from the flat road at the foot of the mountain.

    Someone may ask, isn¡¯t there wear and tear on the suspect¡¯s journey up the mountain?  The answer is yes, but the distance we want is only an approximate value, and certain errors are allowed.

    The investigation experiment is ready. According to the division of labor, Brother Ming is the commander of this experiment, Lao Xian is responsible for recording data, and Pang Lei uses a camera to record the image data of the entire experiment. A Le and I ride alternately. After everything is ready, the investigation  The experiment officially started after the dv "beep" sounded.

    ¡°You wouldn¡¯t know if you didn¡¯t do the experiment, but we were really shocked when we did it. Ale and I rode for nearly 20 kilometers, and the wear characteristics of the wires were consistent with those extracted on site.

    "Is this guy crazy, dragging two bags of corpses and riding so far?" Fat Lei ran all the way carrying the camera, and the exhaustion of his physical strength caused him to collapse several times.

    "No matter what the suspect's purpose is, our experimental results are true and valid." Mingge opened his notebook, "After the meeting in the morning, I contacted the criminal police team to map out the hills where rice can be grown in the city. Unexpectedly, it was better than I thought.  There are many, there are five or six near Longtou Mountain. Combining the conclusions of our reconnaissance experiments, it can be used as an important basis for exclusion."

    Brother Ming closed his notebook and clicked on the map on his mobile phone: "According to the investigation results provided by the criminal police team, there are only two nearby hills that meet the conditions. These two hills are not high. We can search in sunny places."

    "Little dragon."

    "Brother Ming, tell me."

    "If we find a felled tree stump in the mountain, can you confirm whether it was the one cut down by the suspect?"

    "it should be OK."

    "Okay, without further ado, let's search the mountain now."

    Knowing that the trees being cut down are broad-leaved trees, coupled with the characteristics of the annual rings, it is not very difficult to find them.  There are trapezoidal paddy fields planted on the sunny sides of the two target hills, so there is very little tree coverage. After checking the first hilltop, we finally found the suspicious tree stump on the second target hilltop.

    In recent years, the government has vigorously promoted environmental protection. Few people dare to cut trees on the mountain. Although "few" does not mean that there are none. I found a total of three tree stumps of about the same size on the second hill. Because of the types of trees and  The growth conditions are almost the same, and since I don¡¯t have professional measuring instruments, I¡¯m really a bit confused and can¡¯t tell the difference.

    In order to prove that our inference is correct, it is particularly important to confirm the source of the wooden pile. Only when this is confirmed can we proceed with the work. Once this is denied, it means that everything must be overthrown and restarted. From this we can see that we  importance of this conclusion.  But what matters when handling a case is evidence, not emotion. I can't just talk about it just because the conclusion is important. If I don't know, I just don't know. I must tell the truth: "Brother Ming, I'm not sure."

    "How about I give it a try?" It was Lao Xian who spoke.

    "Brother Xian, can you do that?" I was extremely surprised.

    "I can't do it, but the professors from the Chinese Academy of Sciences can."

    "You want to call the professor here?"

    "No, I just need to extract some samples and do DNA comparison."

    "What? DNA? Do you mean plant DNA?" To make sure I heard correctly, I asked again.

    "yes."

    "Plants also have DNA?"

    "Of course there is. It's just that I can't detect it well, but I know there is a professor from the Chinese Academy of Sciences who can. Plant DNA barcoding was an idea proposed by a Canadian scholar in 2003 based on the mitochondrial cytochrome c oxidase gene co1. This idea was later confirmed.  And he also launched an 'International Barcode of Life' project to study this topic. To give the simplest example, we all know the mimosa, but why do the leaves of the mimosa curl up when we touch them? Why  Other plants can¡¯t? It¡¯s all related to the plant¡¯s genetic sequence.¡±

    "If this works, it will be of great help to future cases."

    Lao Xian shook his head: "This technology is not yet mature. Let alone handling the case, it is hard to say whether it can be detected. We can only try our luck.gas.  "

    "If it really doesn't work, I can only cut off the wooden piles and compare them with instruments." I have already thought of the ultimate solution.

    "Look down the mountain." At Brother Ming's suggestion, we focused our attention on the densely packed houses at the foot of the mountain.

    "According to estimates, there are at least several hundred households at the foot of the mountain. The investigation alone will take a long time, so I am too impatient to eat hot tofu, so I asked Guoxian to go to the provincial capital to submit for inspection first. Everyone has been tired recently, so I will take this time to go back and rest.  Let¡¯s talk in a day or two.¡± (Remember the website address: www.hlnovel.com
