civil forensic

In the office, the women were crying like pear blossoms with rain, the men also looked miserable, and the expressions of the policemen were also sympathetic and indignant, with the momentum of fighting against each other and fighting against each other.

Huang Qiangmin's smiling face did not match the overall atmosphere at all.

If anything, 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 could skip a meal if they looked at him a few more times, and went straight to work at the pace of sleepless nights and food.

That's when he came to Baijiang Province, a completely unfamiliar province, Huang Qiangmin used all his little accumulated emotional intelligence.

Unexpectedly, it hit an inopportune moment.

Jiang Yuan followed Huang Qiangmin into the door, followed by the half-pan technician behind him.

When they came in, they stood in an arc around Jiang Yuan's back, talking in whispers with smiles on their faces.It was only then that they found a group of family members of the victim with a gloomy atmosphere, as well as the ugly-looking deputy director and his subordinates.

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

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

"En?" Xu Tian was taken aback, his eyes slid from his own hands to Huang Qiangmin, and then to Jiang Yuan, the legend of "Ningtai Jiangyuan, fierce flames surging" flashed across his mind, and then thought of Huang Qiangmin just now With a smile on his face, a little hope surged up unconsciously: "What result?"

"That... about the case." The director of the trace evidence laboratory looked at the family members beside Xu Tian, ​​how dare he speak out now.

Xu Tian also realized that he was being stupid, and patted his head: "Let's go out and talk."

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

Xu Tian waved his hand: "What I'm talking about is not necessarily your case. Moreover, many plots in the case are classified. You wait here, and I will come to inform you of any new news."

Xu Tian took Huang Qiangmin and Jiang Yuan out after speaking.

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

in the hallway.

Xu Tian walked and said, "I'm sorry, the victim's family was very worried just now, and we are explaining to them, everyone is not in a good mood."

"It's okay, we are a guest army, well, providing emotional value is also the content of the service." Huang Qiangmin smiled without discount.

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

Xu Tian's smile retracted a little.

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

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

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

Xu Tian's smile rose again: "Yes, yes... Where is it?"

"You have to find a satellite map for Jiangyuan, the one with higher accuracy, and I can point it out for you." Huang Qiangmin said the request.

Xu Tian immediately said: "It'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 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 meeting room, and then called out the satellite image that Jiang Yuan wanted.

The technician in the trace evidence laboratory had long hung a paper map beside him, and drew several circles on it with a red pen, all of which he knew had hawthorn trees.

Compared with searching inch by inch on the map, this speed is obviously much faster.Jiang Yuan thought to himself, if he goes back by himself, he should also visit Ningtai County, Qinghe City and Changyang City, knowing the plants in each place well.

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

Next to it, the IT talents sent to the place by the big factory are using the scroll wheel mouse unique to the unit to click on the first marked location and zoom in to the bottom layer.

Jiang Yuan said, "Take a look within 100 meters."

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

Jiang Yuan copied his hands, and when he finished showing, he shook his head and said, "No. Next."

The IT man then immediately moved to another location.

Xu Tian, ​​Huang Qiangmin and the others stood in front of them eagerly. Although there would be no results for a while, they were full of expectations seeing Jiang Yuan's certainty.

Speaking of which, Jiang Yuan is actually a little bit guilty.Therefore, he also turned on the temporary +1 skill.

However, because he didn't have a perceptual understanding of LV3, Jiang Yuan didn't realize how strong LV4's forensic botany was.

Anyway, he just looked at a place and could clearly judge whether it fits the pollen map within minutes.

As for how difficult it is to judge in this way, Jiang Yuan himself has no complete concept.

The Muggles next to him naturally didn't understand even more, they looked at Jiang Yuan's judgments one by one, and felt a little slow.

There are really not many hawthorn trees in Luojin City. The guy from the Trace Evidence Laboratory is really a plant lover and knows the distribution of many plants in the city like the back of his hand.

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 within the main urban area, the workload of searching the suburbs and suburbs will be heavy, so we can only go slowly.

Among all kinds of worries, Jiang Yuan never stopped talking about "next".

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

Huang Qiangmin was like a rabbit being watched by an eagle, his ears stood up instantly.

Xu Tian and the others were belatedly aware of it, and when they looked over, there was still confusion in the corners of their eyes.

"Enlarge and take a look." Jiang Yuan tapped the screen with his finger.

Jiang Yuan chose a city park.

The park is located on the south side of the city, covering 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 extra area was designated as a park.

The location Jiang Yuan pointed to was on the south side of the park, which was 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 serious.

From the perspective of the criminal police, the place Jiang Yuan was referring to was more suitable for burying corpses than Tibetans.

Several technicians in 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 comprehending.

The place Jiang Yuan pointed at was a wasteland with paths but no tall trees.

But it's up, down, left, and right, and there are a lot of plants.

A pollen map is a collection of plants whose core is not variety but proportion.

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

Therefore, if a person has some kind of pollen on his body, if it is an anemophilous 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 contamination on objects is also roughly similar.

This kind of pollen map has a much higher evidentiary value than the pollen of a single species.

What Jiang Yuan is looking at now is the 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 nearby pine trees, it is more reasonable.

"Broaden it a little more, and you can see small plants." Jiang Yuan asked again.

The IT man enlarged the satellite image and saw more plants.

The briar with oval leaves blooms yellow flowers on the side of the road, the oval climbing plants strive to climb the nearby buildings, and the wide oval nettles attract bees and butterflies on the roadside slope...

The relatively rare rice in the city occupies a piece of land, which looks like it has been sown in the wild. Although there are no Chenopodium plants, judging from the overgrown weeds in the rice fields, there should be confusion when looking carefully.

Jiang Yuan made a rough calculation and stopped hesitating. He tapped the screen affirmatively and said, "This is it."

Xu Tian and others, who had been waiting for the result, looked unbelievable, and said, "You found it?"

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

This pollen map is taken from the floor mats and pedals, which means that the passengers in the front and rear seats have left similar maps.

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

In short, they are not here for "life", but only for "things".

"Ju Xu." 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 before he quickly took out his phone.

Not long after, you can hear various voices coming from the corridor.

The task force for this case, as long as it is activated, will have a scale of 30 people or more.

Jiang Yuan said, "I'll go and have a look too."

For forensic botany, it is better to go to the scene to see it more clearly.

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

Cui Xiaohu and the others did not hesitate and followed along.

The cadres of the ministries and committees were all on the front line. Seeing this, Xu Tian had no choice but to follow along. Coupled with the subordinates around him, the scale of departure doubled in an instant.
