Searching counterclockwise along the small lake in the park, Gu Chen's team met He Wenjun's team at a pavilion.

Both teams collected samples from all wildflower locations along the coast.

At this moment, everyone in He Wenjun's team held the samples in their hands.

"How about Officer Gu, how did you collect it?" He Wenjun asked.

"It's okay. Everything that needs to be collected has been collected. What about you? Are there any new discoveries on the shore?"

"No." He Wenjun shook his head and said with a disappointed look on his face: "Except for collecting some wildflower specimens from some places full of wildflowers, no other abnormalities were found."

"That's good." Gu Chen crossed his arms and nodded slightly.

This stunned He Wenjun for a moment.

What does that mean?

Why does this sound so weird?

It feels like there is something in Gu Chen’s words!

He Wenjun also didn't know why and said: "Officer Gu, what do you mean by 'that's good'?"

"The good thing is that we didn't find a second place where we fell into the water. This can confirm that the place we just discovered is indeed the only place where Wang Jinshan fell into the water."

"The only place to fall into the water?" Liu Zhiqiang on the side was confused when he heard this, and quickly asked Gu Chen: "So... did you find the point to fall into the water?"

Gu Chen nodded slightly and said, "Don't say anything. Just come with me and have a look."

He Wenjun looked at his colleagues behind him and waved his right hand: "Let's go over and have a look."

The group of people followed Gu Chen's team in a hurry and arrived at the location that Gu Chen had just discovered.

Gu Chen pointed out the mud marks to He Wenjun: "If this is correct, this should be the source of the dirt in the gaps between Wang Jinshan's nails."

"Indeed." He Wenjun is an old comrade after all. When Gu Chen said this, he quickly understood what Gu Chen meant.

Judging from the scratches in the soil, it was indeed grabbed from the lake to the shore.

There are several nail marks that are particularly obvious.

There are many wild flowers growing in the soil on the shore, and some of them have been destroyed.

He Wenjun quickly took out his mobile phone and took a picture of the scene. Then he turned to look at Gu Chen and said: "It seems that we have found the right place. As you said, this place is most likely the place where Wang Jinshan fell into the water."

."

After thinking about it, He Wenjun asked again: "By the way, have all the wildflower specimens been collected?"

"It's already here." Lu Weiwei held it in her hand and raised it, then explained: "Everything that should be collected has been collected, but Junior Brother Gu is worried that there are other places where such traces will appear, so we have been

Search along the lake until I meet you for confirmation."

"Don't say anything." He Wenjun also waved his hands and said with a look of joy: "We will immediately send this specimen to the Criminal Division to determine as soon as possible whether it is consistent with the pollen properties in the cracks of Wang Jinshan's fingernails."

Looking back at Liu Zhiqiang, He Wenjun said again: "Xiao Liu, take a few people to check the lakeside of the park last night to see if there are any suspicious people. The park management office and the like are running around, and the nearby surveillance cameras are also

Look for them all, and you will definitely find them for me."

"Yes." Liu Zhiqiang nodded when he heard this.

Then he left with two police officers...

He Wenjun followed Gu Chen's team and rushed to the Criminal Division overnight.

When returning to Zhang Hui's testing room, Zhang Hui was still sorting out pollen samples.

But when he heard the movement at the door, Zhang Hui couldn't help but be startled, and quickly asked He Wenjun: "You are a bit fast, how about it? Have you found the sample?"

"Found it." He Wenjun glanced at Gu Chen beside him. Gu Chen took out one of the small evidence collection bags and handed it directly to Zhang Hui and said: "Instructor Zhang, just test this specimen to see if it is the same as Wang Jinshan's.

Are the ingredients in the gaps between your fingers the same?”

"Just test this?" Zhang Hui frowned: "Don't you want to check other things?"

"I won't check anymore." Gu Chen's answer was still affirmative.

Although Zhang Hui didn't understand, he looked at He Wenjun beside him and agreed, "Okay, I'll start testing now. You guys hurry to the door and put on your protective equipment."

"Okay." Everyone agreed readily.

Soon, several people put on protective equipment and protective gloves one after another, and the test on Zhang Hui's end was also progressing rapidly.

Due to the previous detailed detection and analysis of the dirt components in the nail gaps of the deceased Wang Jinshan.

Therefore, Zhang Hui now seems to be able to detect new samples with ease, and his speed is much faster than before.

On the testing platform, Zhang Hui filled in the data on the form on the right while observing through the microscope.

The samples provided by Gu Chen not only include wild flowers, but also soil components.

After repeated comparisons with the dirt previously extracted from the gaps between Wang Jinshan's fingers, Zhang Hui made a surprising discovery.

"Exactly the same?"

Gu Chen quickly bent down and checked the data that Zhang Hui filled in the data form. He also said with a face of joy: "Then the place we are looking for should be right."

"But... how did you find these samples so accurately? Not only are the pollen samples consistent, but the soil and gravel samples are also consistent."

Zhang Hui felt a little incredible, which showed that Gu Chen's efficiency was far beyond his imagination.

He Wenjun explained the reason and said with a smile: "We found some traces in the yard of Wang Jinshan's home, and then we followed the traces and found the park. We found suspicious mud traces by the small lake."

"Yes." Officer Wang also quickly added: "If we calculate it based on the time of Wang Jinshan's death, then the pond in the park should be the scene of the first crime, so the probability is very high, so we will collect data based on the situation at the scene.

As expected, traces were found near the small lake."

"That's great." Zhang Hui stood up and said excitedly: "I can be absolutely sure that the sample extracted from the cracks of Wang Jinshan's fingernails is exactly the same as the sample you just brought for testing."

"That means that the small lake in the park is indeed the scene of the first crime?" He Wenjun crossed his arms and finally breathed a sigh of relief.

But at this time, Zhang Hui asked again: "By the way, besides finding this sample, have you found anything else?"

"Yes." Gu Chen took out his mobile phone, opened the photo album and said, "We found some latest footprints in the woods between Wang Jinshan's home and the park."

"Logically speaking, Wang Jinshan's family lives in a remote location, which is considered a very private location."

"The trail from Wang Jinshan's home to the park is rarely used by people. I think these new footprints are of great investigative value."

"You are right." Zhang Hui sat back in front of a computer and said, "Send me the photos on your mobile phone, and I can use the computer to restore the texture of the soles. Also, where is the data?"

"Everything is recorded." Gu Chen casually picked up a writing pen on the table and started writing on a note paper.

Including the size, length and depth of the shoes, Gu Chen concluded that they were pointed-toe shoes.

After writing some words, Gu Chen said calmly: "Based on the shoe prints we found at the scene, this person's situation is a bit special."

"Special, what do you mean?" Zhang Hui asked.

"The shoe prints at the scene are one deep and one shallow." Gu Chen wrote these on a note paper, turned around and said: "One foot is deep and one foot is shallow. It may be due to the natural length of the legs, or it may be caused by pelvic tilt."

"The sole of such a person's longer foot will have less wear, while the sole of the shorter foot will have greater wear."

"But this type of group with long and short legs is still relatively small, so this is also an indispensable piece of evidence."

"It makes sense." After hearing Gu Chen's words, Zhang Hui nodded silently.

Gu Chen provided himself with too many conditions that he could refer to. At least the length of his legs could be analyzed through trace reasoning of the scene, which was rare.

After receiving the photo of the footprints from Gu Chen, Zhang Hui placed it on the computer screen and continued to expand it.

Zhang Hui soon discovered that the photos at the scene were indeed as Gu Chen said, with the footprints being one deep and one shallow.

But the soil at the site was very deep, which made Zhang Hui curious and turned to look at Gu Chen.

Before Zhang Hui could speak, Gu Chen understood directly and said: "There are two types of footprints. The mark of the toe of the shoe walking towards the lake in the park is the same depth as the shoe print of ordinary people like us."

"But what is very interesting is that the shoe prints facing the courtyard of Wang Jinshan's villa are very deep. They have exceeded his normal weight. At least they are very different from the prints of ordinary people like us."

After looking at Zhang Hui, Gu Chen added: "So I think that this person was carrying another person on his back at that time, so he deepened his footprints, causing the footprints in the direction back to be much deeper than those heading towards Park Lake."

The depth of the footprints on the side.”

Zhang Hui suddenly realized: "So...it is very likely that after the murderer committed the murder by the park lake, he moved the body to the courtyard swimming pool to create the illusion of drowning in the swimming pool."

"Yes, that should be the case." He Wenjun nodded silently, but soon, his cell phone suddenly rang.

He Wenjun answered the phone and said, "Xiao Liu, how is the situation going?"

After a few seconds of silence, He Wenjun nodded: "I understand, bring him here to me, yes, it's the Criminal Division, we are all here."

After hanging up the phone, He Wenjun breathed a sigh of relief, as if he had been relieved.

Zhang Hui glanced at him: "What's going on?"

"The suspicious person has been found." He Wenjun casually found a stool to sit down, and then said involuntarily: "My people discovered from the surveillance at the park management office that Wang Jinshan and his assistant came to the small lake in the park last night.

, Judging from the monitoring situation, it seems that Wang Jinshan is not drunk."

"Haha." When Lu Weiwei heard this, she also hurriedly said: "Sure enough, it was someone close to him who did it. I remember it was this assistant who called the police, right?"

"Yes, that's him." He Wenjun also confirmed.

Gu Chen nodded slightly: "So, Wang Jinshan's assistant is a thief? If he and Wang Jinshan were at the park lake yesterday, then why did he say that he didn't know what happened to Wang Jinshan after he sent Wang Jinshan home?
