Jiang Yuan came to the conference room early, checked the computer, projector, and put a few pages of PPT to try, and then began to ask Qi Changye about the situation at the scene.
Qi Changye was also busy all night yesterday. At this time, he said with blue eyes: "A few people from our brigade have passed by. I also borrowed ten people. Now there are more than a dozen people there. By...by 10 o'clock
Let's hope they are all in place. Some of them had missions before, and they agreed to start their missions from today..."
The work of the police is endless, and Qi Changye's brigade is a typical high-level team. The units and personnel are of relatively high levels, but with a small number of people and a lot of work, they are never too busy.
Even the people he borrowed had original work to do. Police work is not like other jobs. It is not done tomorrow if you say it will be done tomorrow. If criminals do not cooperate, even a case can be delayed.
Endless.
Now is just the beginning of the project. Even if Qi Changye looks forward to it, he cannot go all out. According to Qi Changye's idea, if Jiang Yuan can maintain the speed of the Zhang Lizhen case and find the body in a week or two, it will already be Amitabha——
In fact, Qi Changye just thought about it this way. Xu Taining was still involved in Zhang Lizhen's case, and his case was not so urgent.
Jiang Yuan couldn't care about Qi Changye at this moment. He nodded and said: "When we have a meeting later, I'm going to do some on-site effects. I want the police on site to cooperate. They probably have to run some distance. By the way, the police dogs are here.
?"
"The police dogs have already set off and will be in place in another hour." Qi Changye can shake people off, but he has to follow the Basic Law. Unless there are special circumstances, it is impossible to ask police officers from other units to work overtime. It is better to get up early and work early.
kind.
Jiang Yuan nodded and continued to look at the PPT.
Seeing Jiang Yuan being so serious, Qi Changye naturally felt suspicious in his heart.
His occupational disease made him quickly review the previous conversation between the two, and then he quickly realized something and hurriedly asked: "Captain Jiang, you just mentioned the on-site effect, what kind of on-site effect?"
Jiang Yuan looked at Qi Changye a little surprised, then looked at the empty conference room in front of him, and said, "I considered that the people here this time are all outstanding botanists, and if we simply discuss botany, the effect may not be very good.
I just want to find a few places where corpses are buried and dig on site to see if I can find the corpse on the spot."
"ah?"
Qi Changye really couldn't help it. Isn't this just a joke?
The question is, can it still be played like this?
This is a corpse!
If he could find corpses casually, wouldn't he have suffered in vain these past few years? On those nights when he was drunk and singing, wouldn't he be like a mentally retarded young man "telling his sorrows about composing new words" just to deceive a little girl?
If the body could really be found, wouldn't the technology of forensic botany explode?
Don’t the people’s policemen in every province and city in every country around the world have to get involved in forensic botany?
Don't say it's difficult. Isn't it enough to give you a white shirt if you learn how to do it? You know, nothing is difficult in the world as long as you are given a weave!
So, thinking about it from another angle, the on-site effect mentioned by Jiang Yuan is too ridiculous. If it were discovered just like this... However, the smart Qi Changye thought about it again and realized that this was what Jiang Yuan said!
"Can the body really be found at the scene? Do you already know where the body is? Or..." Qi Changye thought to himself that Jiang Yuan should not think that he would help him bury the body.
Of course, if it's a spy case, and if it can be solved, it's not impossible to think of a way to apply to the higher authorities, or just keep it secret.
But today’s occasion seems to have not reached this level yet…
"I have done some homework yesterday." Jiang Yuan knew that Qi Changye had questions, so he explained in detail: "First of all, if we can find a body, it may not necessarily be the body you want. It may even be
What was found was not a human body!”
Qi Changye nodded, mentally updating the technical points. In fact, if Jiang Yuan only asked him to bury an animal carcass, they could still do this level of cheating, and they were better at it...
Jiang Yuan continued to explain: "The basis for our search for corpses is actually mainly based on the video data captured and captured by drones during Xu Taining's investigation a while ago. I looked at the delineated area last night and I have any questions.
All the points were quietly marked and a certain degree of research was done.”
Jiang Yuan: "Although it's a bit cheating, when it comes to the meeting, I basically just give a case demonstration. More of it requires on-site cooperation. The better the on-site cooperation, the more cases we can present.
Well... the probability of exhuming the body at once is not very high."
Jiang Yuan: "Qi Chu, please coordinate with us."
"No problem, no problem." Qi Changye understood and became worried again: "What if I can't find the body after searching several times, or only find animal carcasses?"
"It doesn't have a shocking effect. It doesn't affect work either."
"That's right." Qi Changye paused and said, "Captain Jiang is quite attentive to these botanists."
"Forensic botany has a heavy workload." Jiang Yuan sighed.
He still needs botanists. Using forensic botany to solve crimes is easy to say, but just looking for pollen under a microscope can blind people. But he wants botanists to accompany him.
Solving the case, without Qi Changye's face, would still be difficult for Jiang Yuan alone.
It's like the botanists in Baijiang Province got together because of Pang Jidong's face.
Otherwise, how could these scholars, who were in their forties or fifty, and were either professors at famous universities or full researchers at research institutes, spend a few days or even longer working with Jiang Yuan.
Not to mention that everyone has their own career plans, academic goals, and work schedules. Even with Jiang Yuan's rank and age, it would be difficult to unite such a group of people.
As for relying on technology and academic ability, Jiang Yuan used image enhancement technology and forensic botany with LV4 to get it done last time, but this time he faced more scholars, and they were all from the capital, so it was difficult to speak fluently.
What's the matter?
If the content of the discussion strays away from forensic botany and involves pure botany - Jiang Yuan can certainly avoid talking about it, but the effect of uniting people will definitely be poor.
After comprehensive consideration, Jiang Yuan decided to link online and offline. His advantage was not simply forensic botany technology.
8:40.
People came into the conference room one after another.
Jiang Yuan only looked up and continued to modify PPT and debug software. From time to time, he would check WeChat on his mobile phone to confirm the manpower situation of each department.
Qi Changye was also typing furiously in the group and making phone calls offline.
The most important thing for online and offline linkage is the human factor, and the second is to ensure the real-time status of various software.
Not to mention the latter, the former is actually always changing.
Just like before today, Jiang Yuan didn't know how many people Qi Changye could find. Qi Changye himself was not sure, so he could only make constant adjustments based on the situation on site.
It would be too naive to think that everyone will cooperate with you.
Even if Jiang Yuan is now a star-level detective, it won't work. A group of men in their thirties and forties, hanging out in the wilderness in the early morning, may take off their clothes for the stars, but they are not necessarily willing to do more for the stars.
Move your butt twice.
After contacting each team and making final confirmation, the alarm clock rang at 9 o'clock.
Jiang Yuan casually pressed the alarm clock, raised his head, turned on the microphone, and said, "Then let's get started."
Below, all fifty seats are occupied.
In addition to the more than 20 botanists from Beijing invited by Qi Changye, Pang Jidong and the four botanists from Baijiang Province he brought over, there were also a group of students and a dozen policemen at all levels.
Jiang Yuan looked over and saw that the faces of the police officers were full of expectation. Among the botanists... Su Lei and Qiao Shengli were the only two people with encouraging looks on their faces.
Jiang Yuan smiled, opened the PPT again, and said: "First of all, thank you for taking the time out of your busy schedule to participate in our case. Criminal cases have their own particularities. There are some regulations below. Please read them by yourself."
After releasing the explanatory page, Jiang Yuan paused for half a minute, and then said: "Today's introduction, I will mainly talk about two parts. One part is the practice of forensic botany, mainly about how we use forensic botany to provide criminal evidence.
Case service. The second part is to try to do some real practical work with the help of some criminal police colleagues."
Following Jiang Yuan's words, the botanists regarded it as a simple description, but the police officers present were already excited.
The policemen were naturally deeply impressed by Jiang Yuan. When they heard him talk about real practical work, they immediately had a true understanding of reality, unlike the botanists present who only thought that reality was a description of a degree.
Jiang Yuan drew another page of PPT and said: "Okay, let's take a look at this video first. This is the K67 plot, the marking method and range. You can scan the map to see it. Let's talk about this plot first... Well, actually
Yes, I watched this video last night. When I watched it, I thought there was something wrong here..."
Jiang Yuan enlarged the picture and landed on a bush.
The botanists present all sat up straight and raised their heads to study. Some of them, like the students who came with them, began to take photos and record them.
"This is birch, elm, pitch pine and fern..."
"It's really problematic to stay in the wild for such a long time."
"Looking at the woods, they only last a few years, no more than 10 years. There is something wrong with this place."
Jiang Yuan waited for half a minute and then said: "In forensic botany, this is a relatively typical situation. We call it a seed bank. Explain to the non-professionals present. A seed bank refers to the underground soil containing
All nearby plant seeds, and the plants on the ground, have stabilized after a long period of competition. But when the soil in a place is disturbed, the newly sprouted plants will produce a new ecology, a new
compete."
"So this area was disturbed a few years ago, and someone dug up the ground to bury corpses? In the wilderness, someone dug up several square meters of land, which is really not normal." A scholar sitting in front immediately followed up and spoke.
Meetings with scholars have such problems. Scholars who have achieved this step are very confident. Once a small meeting like this encounters problems and discussions, it will proceed far beyond the scale.
"Don't some animals have the habit of digging the ground?" A young student also asked in a low voice.
"If you just dig the ground, the plants nearby will invade immediately, and will not give the seeds in the seed bank a chance to grow." Without Jiang Yuan, a scholar explained on the spot: "Only in the case of corpses, the use of autopsy to generate
The corrosive liquid prevents the invasion of surrounding plants, giving new seeds a chance to germinate."
"In other words, there must be a corpse under such a plot?" The student asked in surprise: "Is it so easy to find it?"
"It's not easy to find, because we started from the big map." Jiang Yuan continued to shrink the enlarged map.
As the detailed land plots turned into ordinary maps, all the young people present calmed down.
Give you a map of the country and find out where the bodies are buried - this is probably what they consider forensic botany.
"While the police are inspecting this place, let's talk about another plot, and then discuss the specific process of finding the body." Jiang Yuan said all the practical information, because he would ask these botanists to help with the search later.
For botanists, today's scene is beginning to become exciting.
Botanists also began to understand the true meaning and asked:
"Are the bodies dug up at the scene?"
"What should I do if I dig it?"
"Can you find it? If you find it, it will be a murder case?"
Some people have even begun to eagerly share it with others. Botanists’ group chats and social media have become unprecedentedly lively and eye-catching.
