Chapter 535: This Is It

In the office, the women were crying, the men were also looking miserable, and the police officers had expressions of sympathy but also indignation, and they seemed to be fighting against the same enemy.

Huang Qiangmin's smiling face was completely inconsistent with the overall atmosphere.

To be honest, Huang Qiangmin is usually a very serious person. When he was the captain of the criminal police team, if the people in the criminal police team looked at him a few times, they would skip a meal and go straight to work without sleeping or eating.

It was only when he came to Baijiang Province, a completely unfamiliar foreign province, that Huang Qiangmin used all his little emotional intelligence.

Unexpectedly, it hit me at an inappropriate time.

Jiang Yuan followed Huang Qiangmin through the door, followed by half a plate of technicians behind him.

When they came in, they stood in an arc around Jiang Yuan's back, talking quietly with smiles on their faces. Then I discovered that there was a group of family members of the victims with a gloomy atmosphere across the street, as well as the ugly-looking deputy director and his subordinates.

Facing Huang Qiangmin, Deputy Director Xu Tian couldn't say anything, so he suppressed his anger and said, "What's the matter?"

The director of the Trace Evidence Laboratory quickly said: "Bureau Xu, Bureau Huang, they have achieved results and are here to find you."

"Huh?" Xu Tian was stunned, and his eyes slid from his hands to Huang Qiangmin, and then to Jiang Yuan. The legend of "Ningtai Jiangyuan, fierce flames are surging" flashed through his mind like lightning, and then thought of Huang Qiangmin just now With a smile on his face, a little hope surged up unconsciously: "What's the result?"

"That...about the case." The director of the Trace Evidence Laboratory looked at the family members beside Xu Tian, ​​who dared to speak out now.

Xu Tian also realized that he had made a mistake and patted his forehead: "Let's go out and talk."

"Director Xu!" the family members shouted. They must also want to know the latest situation as soon as possible.

Xu Tian waved his hand: "I'm not necessarily talking about your case, and many of the plots in the case are confidential. Just wait here and I'll come over and let you know when I have any new information."

Xu Tian said and took Huang Qiangmin and Jiang Yuan out.

The police officers who stayed in the office looked at each other, some hurriedly followed him out, and some took out their mobile phones and started asking questions.

in the corridor.

Xu Tian said as he walked: "Sorry, the victim's family was very worried just now. We are also explaining to them. Everyone is not in a good mood."

"It's okay, we are guest troops. Well, providing emotional value is also part of the service." Huang Qiangmin smiled as if there was no discount.

Xu Tian was a little stunned, feeling that Huang Qiangmin's tone was a bit harsh.

Xu Tian's smile faded a little.

At this time, Huang Qiangmin said: "We, Jiang Yuan, have just analyzed the pollen on the car abandoned by the suspect and made a pollen map, which can relatively accurately find the area where the suspect has stayed for a long time."

"Pollen map?" Xu Tian seemed to have heard someone report it to him, but he didn't have any impression of it.

Huang Qiangmin knew that he was also a Muggle, so there was no need for Jiang Yuan to come up and do the analysis. He said directly: "We may be able to find the suspect's hiding place, or their safe house or something like that."

Xu Tian's smile rose again: "Okay, okay...where?"

"You have to find a satellite map for us in Jiangyuan, one with higher accuracy. I can point it out to you by looking at it." Huang Qiangmin made the request.

Xu Tian immediately said: "That's no problem, it's a simple matter."

"That's good, let's go to the conference room. I'll call Cui Ke and the others to come over." Huang Qiangmin sent a message on his mobile phone and called Cui Xiaohu and others to come over.

Xu Tian also called someone from the IT department to the conference room, and then pulled up Jiang Yuanyao's satellite image.

The technician at the Trace Evidence Laboratory had long hung a paper map next to it and used a red pen to draw several circles on it, all of which were places where he knew there were hawthorn trees.

Compared with searching inch by inch on the map, this speed is obviously much faster. Jiang Yuan thought that when he went back, he should visit Ningtai County, Qinghe City and Changyang City to get a good idea of ​​the plants in each place.

After thinking about it, Jiang Yuan's attention quickly returned to the computer screen.

Next to me, an IT talent who was sent to a certain place by a large factory was using the scroll mouse unique to his unit to click on the first marked location and zoom in to the bottom.

Jiang Yuan said: "Look within the 100 meters nearby."

The IT man operated the mouse and keyboard and began to show Jiang Yuan a range of 100 meters nearby.

Jiang Yuan folded his hands, and after he finished showing it, he shook his head and said, "No. Next one."

The IT man immediately moved to another location.

Xu Tian, ​​Huang Qiangmin and others stood in front of them eagerly to watch. Although there would be no results for a while, they were all full of expectations when they saw Jiang Yuan's sure look.

Speaking of which, Jiang Yuan actually felt a little guilty. Therefore, he also opened the temporary +1 skill.

However, because he did not have a perceptual understanding of LV3, Jiang Yuan did not realize how powerful LV4's forensic botany was.

Anyway, he just looks at a place and can clearly judge in minutes whether it matches the pollen map.

As for how difficult it is to make such a judgment, Jiang Yuan himself has no complete idea.

Naturally, the Muggles next to him didn't understand even more. They just looked at Jiang Yuan's judgment one by one and felt that it was a bit slow.

There are not many hawthorn trees in Luojin City. The old man in the trace evidence laboratory is really a plant lover and knows the distribution of many plants in the city.

In addition, he also knows a lot about the places where rice is planted in the city.

Of course, the above is limited to the main urban area.

If there is no harvest in the main urban area, the workload of searching the suburbs and the suburbs will be large, and we can only do it slowly.

Amidst all the worries, Jiang Yuan's "next" never stopped.

Just when everyone was a little tired, Jiang Yuan suddenly said: "Stop!"

Huang Qiangmin was like a rabbit stared at by an eagle, and his ears stood up instantly.

Xu Tian and others realized it later, and when they looked over, there was still turbid confusion in the corners of their eyes.

"Enlarge it and take a look." Jiang Yuan pointed at the screen with his finger.

Jiang Yuan chose a city park.

The park is located on the south side of the city, wrapped in a small hilly landform. The main body is an old private school. It was requisitioned after the founding of the People's Republic of China, and then rebuilt on the original site, and an additional area was marked out to become a park.

The location Jiang Yuan pointed to was on the south side of the park, far from the private school, and also a remote place in the park.

Xu Tian, ​​Huang Qiangmin and others all looked solemn.

From the perspective of a criminal police officer, the place Jiang Yuan pointed to was more suitable for burying corpses than hiding people.

Several technicians from the trace evidence laboratory stretched their heads to look at the area selected by Jiang Yuan, and looked at the plants on the screen, silently experiencing it.

The place where Jiang Yuan pointed to was a wasteland with a path but no tall trees.

But there were a large number of plants above, below, and around it.

The pollen map is a collection of a series of plants, and its core is not the variety, but the proportion.

In fact, if we only talk about the variety, forensic botany is problematic. Because the pollen of many wind-pollinated plants can drift very far. According to records, pollen of some wind-pollinated plants can be found in the Pacific Ocean.

Therefore, if a person has a certain pollen on him, if it is a wind-pollinated plant and the amount is very small, it cannot be determined that he has been in contact with or is nearby.

But the proportion is different. Plants in a small area, especially wind-pollinated plants within a few square meters, face similar environments, so the proportion of objects contaminated is also roughly similar.

This kind of pollen map is much more valuable than the evidence of a single species of pollen.

Jiang Yuan is now looking at the proportion.

From the enlarged satellite map, the proportion of hawthorn trees, birch trees and elm trees near this area is reasonable, and the proportion of pine trees is slightly less, but considering the amount of pine trees nearby, it is more reasonable.

"Enlarge it a little more, so that you can see small plants." Jiang Yuan asked again.

The IT man then enlarged the satellite map and saw more plants.

Wild roses with ovate leaves bloom yellow flowers on the roadside, ovate climbing plants strive to grow on nearby buildings, and broad ovate nettles attract bees and butterflies on the slopes beside the road...

Rice, which is relatively rare in the city, occupies a piece of land alone. It looks like it was sown wild. Although there are no quinoa plants, judging from the overgrown weeds in the rice fields, it should be mixed if you look carefully.

Jiang Yuan roughly calculated it and stopped hesitating. He tapped the screen affirmatively and said, "It's here."

Xu Tian and others who had been waiting for the results seemed unbelievable and said, "Just found it?"

"Well, the three kidnappers must have appeared in this area for a long time." Jiang Yuan's tone was more certain.

This pollen map was taken from the foot pads and pedals, which means that the passengers in the front and back seats all left similar maps.

The identities of the three kidnappers have now been confirmed. Although the three are all unemployed vagrants, their living backgrounds are different and they would not be in this park for no reason.

In short, they will not appear here for "living", but only for "things".

"Director Xu." Huang Qiangmin looked at Xu Tian, ​​and then at Cui Xiaohu who came later.

"I see. Alas, I am a little slow to react." Xu Tian was urged by Huang Qiangmin, and then he quickly took out his mobile phone.

Not long after, various sounds could be heard coming from the corridor.

The special task force for this case, once activated, will have a scale of 30 people or more.

Jiang Yuan said: "I will go and see too."

For forensic botany, it is clearer to see it at the scene.

Huang Qiangmin persuaded him, but he didn't persuade him, so he decided to go with him.

Cui Xiaohu and others did not hesitate to follow him.

The cadres of the ministries and commissions have all gone to the front line, and Xu Tian had to follow them when he saw this. With the addition of the accompanying people around him, the scale of the departure doubled instantly.
