I am a super cop

Chapter 823 What is preventing him from surviving? 【Ask for a monthly ticket】

Gu Chen put on a new pair of gloves, pushed aside the tray next to instructor Zhang Hui, and then asked him: "Instructor Zhang, what do you mean by abnormality?"

"Look at this." Zhang Hui gave up his position and gave Gu Chen the position of the microscope.

Gu Chen directly bowed his body, and after looking at the microscope, he suddenly frowned: "It's... pollen?"

"Yes, it is indeed pollen, and it is also mixed with some soil debris." Zhang Hui said.

Lu Weiwei was stunned: "So... so, this is not the dirt that Wang Jinshan scratched at all?"

"That's true." Gu Chen retracted his gaze, and said with a surprised face: "If Wang Jinshan was swimming in the pool, there would be so many pollen and dirt debris between the nails."

Glancing at Lu Weiwei and Police Officer Wang, Gu Chen asked again: "Senior Sister Lu, Senior Brother Wang, do you still remember the dinner with Wang Jinshan yesterday?"

"What do you want to say?" Lu Weiwei seemed to guess what Gu Chen meant.

Gu Chen walked to Wang Jinshan's body, lifted Wang Jinshan's left hand, and asked, "Did you notice so much dirt on his nails yesterday?"

"Absolutely not." Lu Weiwei affirmed: "Wang Jinshan's hands were very clean when we had dinner yesterday, and there will never be so much dirt."

"Indeed." Gu Chen gently put down Wang Jinshan's left hand: "I sat next to him yesterday, and his hands are indeed not so dirty."

"But the problem is that after he and his assistant left yesterday, the assistant couldn't contact Wang Jinshan until today, and Wang Jinshan has been floating in the swimming pool like this until the police."

"Then it is known that Wang Jinshan died in the early morning of yesterday, and that he died of drowning. Then what happened between the time he left the hotel and his home is the key to the investigation."

"Yes." He Wenjun agreed with Gu Chen's opinion very much, and also took the initiative to agree: "If Wang Jinshan has never gone out since he entered the house, there is no way that there are so many suspicious dirt in the crevices of his fingers."

"And we also searched Wang Jinshan's house at that time. There were almost no flowers in their house, but there were some lawns in the yard."

Officer Wang nodded slightly when he heard the words, and said, "If that's the case, where did the pollen come from? It can only explain one reason. This swimming pool may not be the first scene of the crime."

"It was Wang Jinshan who was drowned in other places, and then moved to the swimming pool of Wang Jinshan's home without anyone noticing it, so as to create the illusion of accidental drowning."

After all, it is to apply what you have learned...

In today's training class, I just talked about the relevant knowledge, and Officer Wang was able to connect immediately.

Liu Zhiqiang nodded slightly: "You're right. There are no flowers at home, so how can there be flower crumbs in the nails? The swimming pool at home is definitely not the first scene."

Discussions started quickly on the spot...

Gu Chen, on the other hand, sat back on the inspection table, observed the pollen matter through a microscope, and then turned to Zhang Hui, "Instructor Zhang, the period from Wang Jinshan's return home to his accidental death is very short."

"If this is the case, then this flower should grow nearby. Do you have any data on file in your laboratory?"

"This..." Zhang Hui was stunned for a moment, and was overwhelmed by Gu Chen's question. He said in embarrassment, "There were some pollen data before, but they were not comprehensive."

"If you want to talk about water quality data, our laboratory has a lot."

"This is not the key anymore." Gu Chen stood up directly and said, "This kind of pollen should be the multiple organs of gymnosperms and angiosperms. It's very small, and you need a microscope to see its structure."

"However, different plants have different pollen shapes. According to the shape, size, symmetry and polarity of the pollen, the structure of the pollen wall and the surface carvings, etc., the family, genus and species of the plant can be identified."

Looking at Zhang Hui, Gu Chen said again: "The pollen of most plants is easy to collect, and it can be stored for a long time without losing its vitality. This kind of plant should be nearby. I want to go and investigate and collect the nearby flowers. It’s better to see the specific ones to determine the location of the crime.”

"But... this is looking for a needle in a haystack."

Just as Zhang Hui wanted to pour cold water on him, Gu Chen turned on the map on his phone, pointed it in front of Zhang Hui, and said, "Mr. A park pond, I want to go there to see, maybe this place is the first crime scene."

"What you said seems to make sense." Hearing Gu Chen's analysis, Zhang Hui nodded silently, then looked at He Wenjun and said, "Old He, what do you mean?"

"I think it's feasible." He Wenjun said.

"That's good." Seeing that the two reached a tacit understanding, Zhang Hui took a deep breath and said, "I will try my best to study the structure of this pollen, so as to determine which category as soon as possible."

"You go to this park pond first, maybe you can find some new discoveries. If there are flowers by the pond, pick them as specimens."

After thinking for a while, Zhang Hui said again: "Remember to number the flowers you pick and the location."

"Understood." Gu Chen nodded slightly, but suddenly remembered that this is the territory of the Yangcheng Police Force, so he asked He Wenjun in a questioning tone: "Officer He, I wonder if there is a chance to partner with your second criminal investigation team."

"Of course this is possible."

Gu Chen asked for a fight, of course He Wenjun was happy.

After all, it is investigation work, and the main task requires more manpower, so one more person means more strength.

Besides, the training class that Gu Chen is in is a self-study time at night, which does not delay the class, so it is a matter of course.

After reaching a cooperation agreement, Gu Chen hurried to the locker in the testing room, found more small evidence collection bags, and then said: "There is no need to delay, we set off immediately."

……

……

He Wenjun and Liu Zhiqiang drove Gu Chen's team and many police officers from the second criminal investigation team to the place where Wang Jinshan died.

This area is a mature community with an early development time and relatively old housing structure.

I heard from a knowledgeable police officer that this place was a villa that Wang Jinshan bought casually when he first made his fortune.

Of course, later Wang Jinshan also bought more villas, which is also a later story.

However, since leaving Jiangguan Fund and starting his own business, Wang Jinshan has been getting off to a bad start, and the fund performance has been losing money year after year.

When Wang Jinshan really can't survive, he will choose to sell a house to relieve the huge financial pressure.

If it weren't for the fact that there were more houses bought in those years, Wang Jinshan might have collapsed today.

Coupled with the extremely high housing prices in Yangcheng, this also gave Wang Jinshan a chance to buffer.

It is said that a listed company invested by Wang Jinshan was in difficulty and was on the verge of bankruptcy.

In order to save this listed company, Wang Jinshan sold a house in the school district of Yangcheng, and then this listed company that was on the verge of bankruptcy came back to life. sum of profits.

Of course, a crisis never exists alone. The poor performance of the funds under his management makes Wang Jinshan have less and less capital to turn the tide.

With the successive sales of houses to save the market, the wealth accumulated by Wang Jinshan over the years was almost emptied.

However, since this villa is the first villa Wang Jinshan earned from working at the Jiangguan Fund, it is of great significance to Wang Jinshan, so it has been preserved intact.

So much so that Wang Jinshan has always liked living here.

After getting a general idea of ​​the villa's situation from the police, Gu Chen crossed the cordon and entered the swimming pool where Wang Jinshan drowned.

At this moment, the water in the swimming pool seemed a bit muddy. Gu Chen checked the surrounding surveillance again, but found that there was no surveillance here, so he couldn't help frowning.

"What's the situation? There's no surveillance around this mansion?" Gu Chen asked He Wenjun.

He Wenjun also quickly explained: "It used to be, but later when we investigated here, we also asked Wang Jinshan's assistant."

"What he means is that Wang Jinshan doesn't particularly like to set up surveillance in the courtyard, because there is a swimming pool in the courtyard, and if there is a problem with the surveillance, it is easy to expose privacy."

"Therefore, in Wang Jinshan's home, there is only one monitoring at the intersection of the road in front of the door. For fear of involving privacy, Wang Jinshan asked people to evacuate all other places."

"Withdrawn?" Hearing He Wenjun's words, Police Officer Wang did not dare to believe it: "Although for a financial tycoon like him, who did he meet? Who did he discuss cooperation with, or who did he have sex with at home? What, these are private."

"Besides, any gossip news may affect the trend of his fund, so these people are usually very cautious, and it is not unreasonable to remove the surveillance cameras in the courtyard."

"Yes." A police officer with a Cantonese accent also said: "This is true, especially since we Cantonese people are used to investing in stocks and funds."

"However, all the bosses and senior management of these listed companies must strictly discipline themselves, otherwise, if some lace news comes out and has a negative impact on the company, the stock price of the fund will plummet all the way."

"So these bosses usually pay attention to personal privacy, probably because they are afraid of hackers invading the monitoring system. This kind of thing has happened before."

"So that's the case?" Officer Wang stopped thinking about it when he heard the words.

It just feels like it's a double edged sword...

Gu Chen walked along the guardrail, and found two obvious friction marks on a low wall.

Then Gu Chen squatted down to check the situation on the floor tiles, and sure enough, he found two traces of friction on the floor tiles.

Seeing Gu Chen's happy face, He Wenjun stepped forward and asked Gu Chen, "Officer Gu, did you find anything?"

"Let's take a look at this." Gu Chen didn't give an answer directly, but stepped aside to show He Wenjun the four rubbing marks on the wall and floor tiles.

He Wenjun frowned, and quickly approached the trace. After repeated confirmation, he looked at Gu Chen in surprise: "You mean... this trace was caused by a ladder?"

"That's right, and it's still very new." Gu Chen also responded directly.

Hearing what the two said, Lu Weiwei, Police Officer Wang and Liu Zhiqiang who were on the side also rushed over.

"Is there a new discovery? What kind of ladder?" Lu Weiwei stepped forward to observe, and instantly understood what Gu Chen meant, and said with a light smile:

"Junior Brother Gu, what do you mean... the murderer probably passed through this place, used a ladder to climb over the wall, and transported Wang Jinshan's body to the swimming pool?"

Gu Chen didn't speak, just nodded slightly.

But Liu Zhiqiang, who was standing aside, said, "Then why don't you go through the gate?"

He Wenjun knocked Liu Zhiqiang on the head: "Stupid, if you go through the gate, wouldn't it be more troublesome to deal with the traces?"

"On the floor, on the doorknob, if there are any traces left, do you think it is easy to clean them up in a short time?"

"Uh, that seems to be the case." After observing the traces near the wall, Liu Zhiqiang suddenly realized: "If the corpse is transported here by ladder, it will save a lot of trouble in cleaning up the traces." .”

"After all, the courtyard is not as exquisite as the home, and it is difficult to be noticed by leaving a small trace."

When Gu Chen heard this, he also nodded slightly: "Officer Liu is very reasonable. The reason why the murderer didn't enter through the gate was because of unnecessary trouble."

"After all, a little trace left in the room is infinitely magnified in the eyes of the police. The murderer would not be so stupid."

Listening to Gu Chen's explanation, Lu Weiwei seemed to understand the reason, so she took a few steps back, and suddenly kicked her right leg back, grabbed the ground with her front foot, and rushed towards the wall.

With the help of kicking her legs, Lu Weiwei climbed up the wall easily, only to find that there was a small forest near the outer edge of the low wall.

"Junior Brother Gu." Lu Weiwei turned to look at Gu Chen.

Gu Chen smiled and asked her: "Did you see a small forest?"

"Yes." Lu Weiwei nodded and said, "That's true, and the wall is actually not high. If you use a ladder, it's easy to climb over."

Gu Chen smiled and said: "That's right. If the murderer climbed over the wall from this place, then according to the map, it's right to pass through the small forest in front of him, which is the pond in the park."

"That is to say, there is a high possibility that the park pond is the scene of the first crime?" Liu Zhiqiang asked.

Gu Chen responded directly: "At present, it is theoretically so, but we still need to collect flowers by the lake as specimens and give them to Instructor Zhang, who will screen and compare them, so as to find out where Wang Jinshan really died."

"Then what are you waiting for?" Police Officer Wang couldn't wait any longer. Scholar Lu Weiwei's run-up action just now jumped up easily and directly climbed over the wall.

Then came Gu Chen, He Wenjun, Liu Zhiqiang and more police officers.

Everyone searched along the path. On the road, many new footprints were also found. These were all photographed and measured by Gu Chen, and various data were recorded for the new footprints.

Coming to the pond in the park, Gu Chen was even more surprised that there are indeed many flowers by the lake, but they are also distributed in small areas, which brings convenience to everyone's search.

Gu Chen pointed to the right side and said, "Officer He, the three of us are looking along the pond on the right side, you go to the left side."

"Yes." He Wenjun readily agreed.

Afterwards, everyone separated at the entrance of the trail, each looking for flowers by the lake.

Gu Chen first came to the first place full of flowers, and after searching the surroundings carefully, he found that there were two types of flowers.

Without further ado, Gu Chen directly took out the transparent evidence collection bag, and put the two kinds of flowers in two small transparent evidence collection bags.

And pick up the stones on the ground, mark the number of the searched location at the lakeside, and then enter the next search location.

It wasn't until Gu Chen walked along the lake to the third place full of flowers that he realized that this was a deep water embankment, and the river bank was perpendicular to the water.

Gu Chen frowned, using his specialized observation skills, he began to focus on the embankment by the lake.

But when he was walking along the lake and was about to finish the place where the flowers grew, Gu Chen accidentally discovered that there seemed to be some deep scratches in the soil by the river bank.

Gu Chen quickly squatted down and took a picture of the scratches with his mobile phone.

Lu Weiwei, who was searching another place on the river bank, discovered Gu Chen's little tricks, so she hurried forward and asked, "Junior Brother Gu, did you find anything?"

"Let's see what this is?" Gu Chen also stepped aside, pointing to the scratches beside the embankment.

Lu Weiwei frowned slightly, and quickly squatted beside Gu Chen, then said in shock: "This... isn't this a trace of finger scratching?"

"Traces of scratching?" Hearing that Gu Chen found something, Police Officer Wang hurried over.

Gu Chen nodded slightly, and said with a serious face: "Yes, it is indeed a scratch of human hands, and have you noticed that this scratch is from the opposite direction, from the lake upwards."

"Let me see." Reminded by Gu Chen, Lu Weiwei quickly stretched out her palm for comparison.

Since the mud marks were not particularly obvious, after comparison, Lu Weiwei really found the merits, and suddenly said with surprise:

"That's right, it was pulled out from the lake. Look, the outside is a bit high, and the inside is deep. This is obviously a mud pit in the dark of a few fingers."

"Get out of the lake and grab it desperately?" Officer Wang frowned slightly, then glanced at the flowers around him, and immediately said: "The lake is still full of wild flowers. Could this be the place where Wang Jinshan died?"

"Basically it should be right." Gu Chen picked off a few wild flowers next to the mud marks, put them in a small transparent evidence collection bag, and then specially drew a circle around the number with a pen.

"In order to check the integrity, we also have to walk around the small lake to make sure that there is only this scratch around the entire small lake."

"No problem." Although Lu Weiwei knew it, based on this, it was already obvious that everyone's previous deduction was correct, and Wang Jinshan might indeed have been drowned here.

That is, when Wang Jinshan was about to drown, he desperately grabbed everything he could grab on the shore, trying to climb up.

This is why, there will be dirt and pollen powder in the crevices of Wang Jinshan's fingers.

"But what is preventing him from surviving? The murderer?" Lu Weiwei thought deeply.
