Chapter 752 On-Site Effect

8 o'clock in the morning.

Jiang Yuan came to the meeting room early, checked the computer and projector, and played a few pages of PPT to test it. Then he began to ask Qi Changye about the situation on the scene.

Qi Changye was also busy all night yesterday. At this time, he said with dark eyes: "Several people from our brigade have gone there. I borrowed ten more people. Now there are more than ten people there. By... around 10 o'clock, they will all be in place. Some people had tasks before, and they agreed to start their tasks from today..."

The police have endless work to do. Qi Changye's brigade is a typical high-level team. The level of the unit and personnel is relatively high, but there are few people and a lot of work, so they are always busy.

Even the people he borrowed have their original work to do. Police work is not like other things. It is not that if it is agreed to be done tomorrow, it will be done tomorrow. If the criminals do not cooperate, a case can be dragged on endlessly.

Now is just the beginning of the special project. No matter how much Qi Changye expects, he can't do it with all his strength. According to Qi Changye's idea, if Jiang Yuan can keep up the speed of Zhang Lizhen's case and find the body in one or two weeks, it would be a blessing - in fact, Qi Changye just thought so. Zhang Lizhen's case is also suitable for Xu Taining, and his case is not so urgent.

Jiang Yuan couldn't care about Qi Changye at this moment, nodded, and said: "I plan to do some on-site effects during the meeting later. I need to ask the police on the scene to cooperate more. I guess I have to run some distance. By the way, has the police dog arrived?"

"The police dog has set off and will be in place in another hour." Qi Changye can mobilize people, but he also has to abide by the basic law. Unless there is a special situation, it is impossible to ask the police from other units to work overtime, or to get up early and work in advance.

Jiang Yuan nodded and continued to look at the PPT.

Qi Changye saw Jiang Yuan so serious, and naturally a sense of doubt arose in his heart.

His occupational disease made him quickly recall the previous conversation between the two, and then he quickly realized something and asked hurriedly: "Captain Jiang, you just mentioned the on-site effect, what kind of on-site effect?"

Jiang Yuan looked at Qi Changye with a little surprise, then looked at the empty conference room in front, and said: "I took into account that the people who came this time were all outstanding botanists. Simply discussing botany may not be very effective. I just want to find a few burial sites on the spot, dig on the spot, and try to find the body on the spot."

"Ah?"

Qi Changye really couldn't help it. Isn't this fun?

The problem is, can it still be played like this?

This is a corpse!

If the body can be found casually, wouldn't I have suffered in vain in the past few years? Wouldn't the night of drunken singing be like a mentally retarded young man "making up new words to make up sorrow" in order to deceive a little girl?

If the body can really be found, wouldn't the technology of forensic botany explode?

The people's police in every country and every province and city in the world have to learn forensic botany!

Don't say it's difficult, isn't it enough to give a white shirt after learning it? You know, nothing is difficult in the world except for the establishment!

So, from another angle, the on-site effect Jiang Yuan said was too ridiculous. If it was discovered like this... But the smart Qi Changye thought about it, this was what Jiang Yuan said!

"Can we really find the body on the scene? Do you already know where the body is? Or..." Qi Changye thought, Jiang Yuan should not think that he would help him bury the body.

Of course, if it is a spy case, if it can be solved, think of a way to apply to the higher-ups, or just hide it from yourself, it is not completely impossible to consider this aspect.

But today's occasion does not seem to have reached this level...

"I did some homework yesterday." Jiang Yuan knew that Qi Changye had questions, and explained in detail: "First of all, we can find the body, but it may not be the body you want, and it may not even be a human body!"

Qi Changye nodded, and was also updating the technical points in his heart. In fact, if Jiang Yuan only asked him to bury an animal corpse, they could still cheat to this extent, and they were quite good at it...

Jiang Yuan continued to explain: "The basis for us to find the corpse is actually mainly the video data captured by the drone search and shooting when Xu Taining was investigating a while ago. I looked at the divided area last night, quietly marked the points with questions, and did some research."

Jiang Yuan: "Although it was a bit of cheating, when it came to the meeting, I basically just demonstrated a case. It still depends more on the cooperation on the spot, and the cooperation on the spot is effective. The better the results, the more cases we can present. Well... the probability of digging out a body at once is still not very high. "

Jiang Yuan: "Director Qi, please coordinate and cooperate on your side."

"No problem, no problem." Qi Changye understood and became worried again: "What if we can't find the body after searching for several times, or only find animal bodies?"

"It won't achieve a shocking effect. It won't affect the work."

"That's true." Qi Changye paused and said, "Captain Jiang is very attentive to these botanists."

"Forensic botany has a lot of work." Jiang Yuan sighed.

He still has a need for botanists. Using forensic botany to solve crimes sounds simple, but just looking for spores under a microscope can blind people. But if he wants botanists to accompany him to solve the case, it will be difficult for Jiang Yuan to do it alone without Qi Changye's face.

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 Jiang Yuan's level and age make it 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 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 is 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. A group of men in their 30s and 40s, soaking in the wilderness in the early morning, may take off their clothes for the sake of celebrities, but they are really not necessarily willing to move their buttocks a few more times for the sake of celebrities.

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 were 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 expectations on the faces of the police officers. 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 upright 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 it to the non-professionals present. The seed bank refers to the underground soil, which contains 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 immediately invade, and there will be no chance for the seeds in the seed bank to grow." Without Jiang Yuan, a scholar explained on the spot: "Only in the case of a corpse, the corrosive liquid produced by the autopsy can prevent the invasion of surrounding plants, and then there will be a chance for new seeds to germinate."

"In other words, there must be a corpse under such a plot of land?" The student was surprised: "Is it so easy to find?"

"It's not easy to find, because we started from the big map." Jiang Yuan said as he continued to shrink the enlarged map.

As the detailed plot of land turned into an ordinary map, all the young people present calmed down.

Give you a national map and find the place where the body is secretly buried - this is probably what they think of forensic botany.

"While the police are checking this place, let's talk about another plot of land, and then discuss the specific process of finding the body." Jiang Yuan said all the dry goods, because he would need these botanists to help search later.

For the botanists, today's scene began to become exciting.

Botanists also began to understand the true meaning and asked:

"Are we digging up the body at the scene?"

"What if we find it?"

"Can we find it? If we find it, it means it's a murder?"

Some people even began to share it with others eagerly. The group chats and social media of botanists were unprecedentedly enthusiastic and eye-catching.
