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

Both teams collected samples of all the wildflower-infested sites 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.

"Okay, everything that should be collected has been collected, what about you, are there any new discoveries on the shore?"

"Nope. He Wenjun shook his head, and said with a disappointed face: "Except for some places full of wildflowers, and some wildflower specimens were collected, nothing abnormal was found. ”

"That's good. Gu Chen clasped his hands to his chest and nodded slightly.

This stunned He Wenjun for a moment.

What do you mean by that?

Why does that sound weird?

I feel that Gu Chen has something to say!

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

"Well, we didn't find the second place where we fell into the water, so we can be sure that the place we found just now is indeed the only place where Wang Jinshan fell into the water. ”

"The only point of falling into the water?" Liu Zhiqiang on the side also heard it in a fog, and hurriedly asked Gu Chen: "So...... Did you find the sinkhole?"

Gu Chen nodded slightly, and said, "Don't say anything, you can just come over with me and take a look." ”

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

The group followed behind Gu Chen's team in a hurry, and came to the location that Gu Chen had just discovered.

Gu Chen pointed out the mud marks to He Wenjun: "If that's right, this should be the source of the dirt in the cracks of Wang Jinshan's nails." ”

"Definitely. After all, He Wenjun was an old comrade, and when Gu Chen said this, he quickly understood what Gu Chen meant.

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

There are a few nail marks that are particularly noticeable.

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

He Wenjun hurriedly took out his mobile phone and filmed the scene, then turned his head to look at Gu Chen and said, "It seems that we have found the right place, and it is really as you said, this place is very likely to be Wang Jinshan's falling point." ”

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

"It's already here. Lu Weiwei took it in her hand and raised it, and then explained: "Everything that should be collected has already been collected, but Senior Brother Gu is worried that there are other places where this kind of trace will also appear, so we have been searching along the lake until we meet you to confirm." ”

"Don't say anything. He Wenjun also waved his hand and said with a happy face: "We will immediately send this specimen to the Criminal Department as soon as possible to determine 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, you take a few people, check last night by the lake in the park, see if there are any suspicious people, the park management office or something, and the nearby monitoring is also for me to see, I must find out." ”

"Yes. When Liu Zhiqiang heard this, he also nodded in response.

He then left with two police officers......

And He Wenjun followed Gu Chen's team and rushed to the criminal department overnight.

When he returned to Zhang's testing room, he was still combing through the pollen samples.

But when he heard the movement at the door, Zhang Hui couldn't help but be stunned, and hurriedly asked He Wenjun: "You guys are a little fast, how are you?

"Found it. He Wenjun glanced at Gu Chen beside him, Gu Chen took out one of the small forensic bags, handed it directly to Zhang Hui and said, "Instructor Zhang, you can test this specimen to see if it is the same as the ingredients in the gap between Wang Jinshan's fingers?"

"Just test this?" Zhang Hui frowned: "Don't check the others?"

"Don't check it anymore. Gu Chen's answer was still affirmative.

Although Zhang Hui didn't understand, he looked at He Wenjun beside him and had no opinion, so he also agreed: "Okay, I'll start testing now, you guys hurry to the door and put on the protective equipment." ”

"Okay. Everyone readily agreed.

Soon, several people put on protective equipment one after another, and when they put on protective gloves, Zhang Hui's inspection was also advancing rapidly.

Due to the previous meticulous detection and analysis of the dirt components in the fingernails of the deceased Wang Jinshan.

Therefore, now that the new samples are being tested, Zhang Hui seems to be at ease and much faster than before.

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

The samples provided by Gu Chen included not only wildflowers, but also soil components.

After repeated comparisons with the dirt extracted from Wang Jinshan's fingers, Zhang Hui made an astonishing discovery.

"Exactly?"

Gu Chen hurriedly bowed down and checked the data filled in by Zhang Hui in the data form, and said with a happy face: "In that case, the place we are looking for should be correct." ”

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

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 house, and then followed the traces all the way, found the park, and found suspicious mud marks by the small lake. ”

"Yes. Officer Wang also hurriedly added: "If you calculate according to the time of Wang Jinshan's death, then the pond in the park should be the scene of the first crime, so this probability is very high, we also collected samples according to the situation at the scene, and sure enough, traces were found by the small lake." ”

"It's amazing. Zhang Hui stood up and said excitedly: "I can be completely sure that the sample taken from the gap between Wang Jinshan's fingernails is completely consistent with the sample you just took for testing." ”

"That is to say, the small lake in the park is indeed the scene of the first crime?" He Wenjun clasped his hands to his chest, and finally breathed a sigh of relief.

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

"Yes. Gu Chen directly took out his mobile phone, clicked on the album and said, "We found some of the latest footprints in the grove between Wang Jinshan's house and the park. ”

"It stands to reason that Wang Jinshan's family lives in a backing position, which is already a very secret location. ”

"The path from Wang Jinshan's home to the park is rarely walked, and I think these new footprints are very valuable for investigation. ”

"You're quite right. Zhang Hui sat back in front of a computer and said, "Send me a photo of your mobile phone, I can use the computer to restore the sole texture, in addition, what about the data?"

"It's all recorded. Gu Chen casually picked up a writing pen on the table and began to write on a piece of sticky note paper.

Including the size length of the shoe and the depth of the shoe size, Gu Chen concluded that it was a pointed scalp shoe.

After writing, Gu Chen said lightly: "According to our shoe prints on the scene, this person's situation is a bit special. ”

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

"The shoe prints on the scene are one deep and one shallow. Gu Chen wrote these on the sticky note paper, turned his head and said, "One foot deep and one foot shallow, it may be a natural long and short leg, or it may be caused by a lateral pelvic tilt." ”

"This kind of person has less wear on the sole of the longer foot, and more wear on the sole of the shorter foot. ”

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

"Makes sense. Hearing Gu Chen's words, Zhang Hui also nodded silently.

Gu Chen provided himself with too many conditions that he could refer to, at least long and short legs, which could be analyzed by reasoning from the traces of the situation on the scene, which was rare.

After getting the photo of the footprints on the spot sent by Gu Chen, Zhang Hui put it on the computer screen and continued to expand.

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

But the depth of the soil at the scene was very large, which made Zhang Hui couldn't help but be curious, and turned his head to look at Gu Chen.

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

But what is very interesting is that the shoe prints on the toe in the direction of the courtyard of Wang Jinshan's villa are very deep, which has exceeded his normal weight, at least there is still a big difference from the depth of our ordinary people's footprints. ”

Looking at Zhang Hui, Gu Chen said again: "So I think that this person should have been carrying another person on his body at that time, so he deepened his footprints, causing the direction of return, the depth of the footprints is much greater than the depth of the footprints going to the park lake." ”

Zhang Hui suddenly realized: "So...... It is likely that the murderer carried the body to the courtyard pool after committing the murder by the lake in the park to create the illusion of drowning in the pool. ”

"Yes, that's how it should be. He Wenjun nodded silently, but soon, his mobile phone suddenly rang.

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

After being silent for a few seconds, He Wenjun nodded: "I know, you guys brought him to me, yes, it's the Criminal Division, we are all here." ”

Hanging up the phone, He Wenjun breathed a sigh of relief, as if he was relieved.

Zhang Hui glanced at him: "What's the situation?"

"Suspicious people have been found. He Wenjun casually found a stool and sat down, and then couldn't help but say: "My people found in the monitoring of the park management office that Wang Jinshan and his assistant came to the small lake in the park last night, and from the monitoring situation, it seems that Wang Jinshan was not drunk. ”

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

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

Gu Chen nodded slightly: "In that case, Wang Jinshan's assistant is a thief shouting to catch a thief? If he came to the park and lake with Wang Jinshan yesterday, then why did he say that after he sent Wang Jinshan home, he didn't know what happened after Wang Jinshan? This is obviously a lie." ”

After thinking about it, Gu Chen asked again: "However, even if Wang Jinshan's assistant wants to do it, then he should pay attention to the monitoring range in the park, right? At least he should choose a more secret place to do it again, so as not to be captured by the park monitoring, is it because he is careless?"

"It should be. He Wenjun walked among the crowd, and then explained to everyone the situation reported by Liu Zhiqiang just now:

"As is the case, the park management office has recently added a new surveillance camera, which looks like a simulated tree and may not be easy to identify. ”

It was this very secret camera that captured the assistant and Wang Jinshan's activities in the park. ”

But he never appeared again, probably from another location, but at least it proved that Wang Jinshan's assistant had nothing to do with Wang Jinshan's death, because the situation he reported to the police did not correspond to reality. ”

"Yes, there must be a situation. Zhang Hui also agrees with this.

Especially the shoe print data provided by Gu Chen for reasoning, if it is true, then this Wang Jinshan's assistant must also be a long and short leg.

Thinking of this, everyone in the entire testing room began to get excited.

......

......

About an hour and a half passed, and when He Wenjun, Zhang Hui, and Gu Chen's team had finished dinner outside the testing room, Liu Zhiqiang and several other police officers arrived late with Wang Jinshan's assistant.

"Why has it been so long?" He Wenjun stared at Liu Zhiqiang, and he didn't have a good air.

"This guy is jumping in a bar, there are too many people, it's really not easy to find him, be considerate. ”

Liu Zhiqiang touched his stomach, and couldn't help but say: "I haven't eaten dinner yet, just to find him." ”

"Then you can go eat now, and leave it to me here. He Wenjun walked up to Wang Jinshan's assistant and shook his hands at both sides.

The other police officers, only then did they "sigh", and then left listlessly.

"Hehe, comrade policeman, I said that this matter has nothing to do with me, really. The assistant looked at He Wenjun with a little panic.

He Wenjun didn't say anything, his right hand was directly on his shoulder, and then pinched the back of the assistant's neck, and said, "Come with me to talk next door." ”

The place where He Wenjun wanted to take his assistant was the first lounge outside the testing room.

Gu Chen, Officer Wang, and Lu Weiwei looked at each other, and they all followed.

Everyone sat down casually in the lounge.

He Wenjun saw that the law enforcement recorder was turned on and placed in a suitable position, so he asked the assistant to sit in the direction where the lens of the law enforcement recorder was pointed.

At this moment, Wang Jinshan's assistant was panicked, his hands were clenched tightly together, and his face became extremely ugly.

He Wenjun sneered and asked him: "Your boss drowned, but you are chic, run to the bar to jump, do you feel liberated?"

"Hehe, comrade policeman, how can you say that?" The assistant frowned and said with some embarrassment: "I've been under too much pressure recently, so I went to the bar for fun, what does this have to do with my boss's drowning?"

"It doesn't matter if it's true or not, you know it yourself. Gu Chen walked to a suitable position and found a stool to sit down first.

At this moment, the assistant remembered where he had seen Gu Chen, and suddenly realized: "Oh, aren't you the one who had dinner with Mr. Wang yesterday......? We've also met on high-speed rail. ”

When the words fell, the assistant suddenly became a little emotional: "What...... You're a police officer?"

"Didn't you look at it all in uniform?" Lu Weiwei was also not angry.

The assistant was stunned for a moment, and suddenly lowered his tone and said, "Look...... It seems that we still have some fate, and we can meet three times. ”

"You ......"

"What's your name? ”

Before He Wenjun could speak, Gu Chen directly had a preconceived idea and asked about the assistant's personal information.

The assistant pursed his lips, and then replied: "My name is Liu Kai, and my ID number is ......."

According to Gu Chen's meaning, Liu Kai gave out the personal information one by one.

Gu Chen nodded slightly, and asked again: "So, you are the first person to find Wang Jinshan drowning in your own pool?" That is to say...... You're the first witness, right?"

"Yes, that's true. Liu Kai nodded fiercely, and said nervously: "After I sent Mr. Wang home, I couldn't contact him until noon today, so I went to Mr. Wang's house to have a look, but found Mr. Wang's body floating in the pool in the yard, so I was so frightened that I called the police." ”

"As for the ...... later"

Glancing at He Wenjun, Liu Kai said again: "As for the future, your police also know the situation. ”

"......"

"But you're lying. Still before He Wenjun could speak, Gu Chen directly interrupted: "I don't want to go around the bend with you, I basically know the situation of your confession, you said that you left after sending Wang Jinshan home, but you still can't contact Wang Jinshan until noon today." ”

"But this is not the same as the situation you and Wang Jinshan had last night by the small lake in the park near the villa. ”

Seeing that Liu Kai was a little flustered, Gu Chen asked again: "Then I want to ask you, what are you doing by going to the park lake on this big night?"

"Uhhhh......h What? Let's go to the park lake? This ...... How do you see this?"

Liu Kai smiled bitterly and hurriedly asked.

He Wenjun seized the opportunity to speak, and then hurriedly said: "How do you know what do you know?

There was a sudden silence......

Liu Kai was stunned, and the whole person was stunned for a few seconds, and then he burst out laughing.

He Wenjun frowned, and asked angrily, "What are you laughing at?"

"It's not. Liu Kai waved his hand, and quickly changed the topic: "I didn't expect you to even ask this?"

After trying to calm himself down, Liu Kai said again: "That's right, after I sent Mr. Wang home, he said that he was in a bad mood and wanted to go to the lake for a walk." ”

"Then I, as an assistant, have to follow, right? I'll just go to the lake and we'll leave, it's very short, so I don't think there's any need to tell you police so clearly. ”

Glancing at He Wenjun, Liu Kai said again: "But, you can't bring me here because of this, right?

"Hehe, is this called missing details?" He Wenjun also snorted bitterly, and said angrily: "You are deliberately concealing it, right?"

......
