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, the people in the criminal police team would skip a meal if they looked at him a few times, and they would 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 in 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 said quickly: "Bureau Xu, Bureau Huang, they have achieved results and are here to find you."
"Huh?" Xu Tian was stunned. 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. Then he 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 if 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, and 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 after analysis."
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, and I'll call Cui Ke and the others to come over." Huang Qiangmin sent a message on his mobile phone, calling Cui Xiaohu and others to come over.
Xu Tian also called someone from the IT department to the conference room and 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 floor.
Jiang Yuan said: "Look within the 100 meters nearby."
The IT man operated the mouse and keyboard and began to show Jiang Yuan the nearby 100-meter range.
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 really not many hawthorn trees in Luojin City. This man from the Microevidence Laboratory is really a plant enthusiast and knows the distribution of many plants in the city.
In addition, he also knew a lot about the places where rice was grown in the city.
Of course, the above is limited to the main city area.
If there is no harvest within the main urban area, the workload of searching the suburbs and outskirts will be huge, and we can only go through it slowly.
Amidst all the worries, Jiang Yuan never stopped saying "next".
Just when everyone was feeling tired, Jiang Yuan suddenly said: "Stop!"
Huang Qiangmin was like a rabbit being stared at by a hawk, his ears immediately stood up.
Xu Tian and others realized it later. When they looked over, there was still confusion in the corners of their eyes.
"Enlarge it and take a look." Jiang Yuan pointed at the screen.
Jiang Yuan chose a city park.
The park is located on the south side of the city, covering a small hilly landscape. The main body is an old private school. It was expropriated after the founding of the People's Republic of China, and then rebuilt on the original site, and an extra area was designated as a park.
The location Jiang Yuan pointed to was on the south side of the park, far away from the private school, and it was also a remote place in the park.
The expressions of Xu Tian, Huang Qiangmin and others became 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 appreciating it.
Where Jiang Yuan pointed was a wasteland with paths but no tall trees.
But there are a lot of plants above, below, left and right.
A pollen map is a collection of plants whose core is not variety but proportion.
In fact, forensic botany is problematic if we only talk about species. Because the pollen of many wind-pollinated plants can travel very far. According to records, pollen from certain wind-pollinated plants can be found in the Pacific Ocean.
Therefore, if there is a certain type of pollen on a person's body, 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 nearby.
But proportions are different. Plants in a small area, especially wind-pollinated plants within a few square meters, face similar environments, so the proportions of contamination onto objects are generally similar.
This kind of pollen map has much higher evidential value than the pollen of a certain species alone.
What Jiang Yuan looks at now is proportion.
Judging from the enlarged satellite image, the proportion of hawthorn, birch and elm trees near this area is reasonable, and the proportion of pine trees is slightly less. However, considering the amount of pine trees nearby, it is more reasonable.
"Expand a little further and you can see small plants." Jiang Yuan asked again.
The IT man then expanded the satellite image and saw more plants.
The ovate-shaped roses bloom with yellow flowers on the roadside, the oval-shaped climbers are climbing up the nearby buildings, and the wide-ovate nettles are attracting bees and butterflies on the roadside slope...
Rice, which is relatively rare in the city, occupies a piece of land. It looks like it has been sown in the wild. Although there is no Chenopodiaceae plant present, judging from the overgrown weeds in the rice field, if you look carefully, there should be some confusion.
Jiang Yuan made a rough calculation, no longer hesitated, tapped the screen with certainty, and said: "This is it."
Xu Tian and others, who had been waiting for the result, looked in disbelief and said, "Just found it?"
"Well, the three kidnappers must have been in this area for a long time." Jiang Yuan's tone became more certain.
This pollen map was taken from the floor mats and footrests, which means that the passengers in the front and rear seats all left similar maps.
The identities of the three kidnappers have now been confirmed. Although the three are all homeless, they have different life backgrounds and would not be in this park for no reason.
In short, they are not here for "life", only for "things".
"Xu Bureau." Huang Qiangmin looked at Xu Tian and then at Cui Xiaohu.
"Understood. Hey, I didn't react a bit." Xu Tian was urged by Huang Qiangmin, and then he quickly took out his mobile phone.
Before long, you can hear various sounds coming from the corridor.
As long as the task force for this case is activated, it will have a scale of 30 people.
Jiang Yuandao: "I'll go take a look too."
For forensic botany, it would be clearer to go to the scene and have a look.
Huang Qiangmin tried to persuade him, but without being persuaded, he decided to go along.
Cui Xiaohu and others did not hesitate and followed.
The cadres of the ministries and commissions were all on the front line. When Xu Tian saw this, he had no choice but to follow him. Coupled with the subordinates around him, the scale of the departure instantly doubled.
