I feel that foodies also have this day, and Officer Wang said in his heart that he can be regarded as catching your Lu Weiwei's life, and I am afraid that I will not be able to cure you little girl in the future?

However, at this moment, not only Lu Weiwei, but also young police officers Ding Liang and Huang Zunlong also have varying degrees of nausea.

The two of them are in good health, but it is too disgusting to stand the corpse.

On the surface, the body apparently had been silent in the lake for several days, covered in aquatic weeds and crabs.

It can be seen that the corpse has long become the food of the aquarium.

However, when everyone was disgusted, everyone realized that only Gu Chen and Officer Wang were on the boat without any symptoms.

Especially Gu Chen, he still jumped directly into the lake and dragged the corpse to the splint.

Officer Wang is an old comrade, and in the years that he followed Zhao Guozhi to the police, he had seen corpses that were even more mutilated and disgusting than this.

At that time, I got used to spitting and spitting......

So look at it now, it's all pediatric, only rookies will vomit, and Officer Wang can't afford to lose this person.

Seeing that Ding Liang was no longer suitable to be a "captain", Gu Chen took the initiative to walk on the bridge and said, "You guys sit back and rest, I'll drive the boat." ”

"Okay, I'll leave it to you. After Ding Liang handed over the driver, he staggered back to a vacant seat.

Just now I joked that Xiaogang was seasick, but at this moment, I was disgusted by the corpse.

Gu Chen started the speedboat and drove directly towards the shore.

The lake was breezy at night, but the people on the splint kept smelling the stench of corpses throughout the way back.

While Gu Chen was sailing, he said to Officer Wang: "Senior Brother Wang, by the way, contact the Technical Department of the Municipal Bureau and ask the Liu Forensic Team to come over." ”

"No problem. Officer Wang took out his mobile phone and began to contact Forensic Doctor Liu directly.

A decomposed corpse like this must also rely on the professional testing of the forensic team to confirm and identify the corpse.

When I returned to the shore, the manager of the Yangtian Lake Hotel and some company employees were already standing on the shore and waiting anxiously.

As soon as the boat docked, a man who looked like a manager hurriedly called for his subordinates to help fix the rope.

"Hurry up, tie the rope. ”

"Who's going to take a hand and bring all the seasick people up. ”

"Where's the water? Bring some bottles of mineral water and wash them. ”

Seeing that Gu Chen was on the dock without any energy, the person who looked like a manager hurriedly came over to say hello.

"Comrade policeman, I don't know if you came to visit late at night, why did you still drive the boat by yourself? I knew that you were going to the middle of the lake, so I would have asked a few people to accompany you. ”

"Are you the manager?" listened to the manager's beep for a long time, and then Gu Chen asked him.

"Yes. The manager nodded silently, quickly took out a business card from his pocket and handed it to Gu Chen: "I am the manager of Yangtian Lake Hotel, my name is Xiao Lei, this is my business card." ”

Gu Chen caught it with both hands, and then asked, "Do you know that your hotel staff Liu Biao is missing?"

"You know, how can you not know, he probably went to hide from debt. ”

Seeing Gu Chen's sharp eyes, Xiao Lei frowned: "Comrade policeman, you came to visit late at night today, wouldn't you just come to find Liu Biao?"

"You guessed it. Gu Chen didn't go around the bend with him, and said straightforwardly: "Liu Biao is involved in a case, and we are here to find him today." ”

But Liu Biao's roommate, Xiao Gang, told me that Liu Biao had been missing for some time, and that before he disappeared, he even wore shoes to sleep. ”

"Do you have to wear shoes when you sleep?" Xiao Lei frowned slightly when he heard this: "This ...... I haven't heard of this, but Liu Biao often gets into trouble, and it is estimated that there are many people who trouble him, and we feel that he should go out to hide from debts. ”

"Then what do you say about this corpse?" Gu Chen said as he stepped aside and pointed to the corpse on the splint of the speedboat.

"Corpse?" Xiao Lei was stunned, then quickly ran to the dock and glanced at the speedboat plywood.

Suddenly, Xiao Lei's cheeks puffed out, he quickly covered his mouth and ran back to Gu Chen's side.

"This ...... What the hell is this? How can there be a corpse? This corpse ...... How is this corpse still mutilated like this?"

"Corpses?"

The crowd who had been patronizing the crowd before had only stopped their attention on the speedboat splint for the first time.

At this moment, the mutilated headless corpse was lying flat on the splint.

A moment later, several waitresses suddenly let out a burst of exclamation and quickly got into the arms of the waitress.

At this moment, Gu Chen called Xiao Gang and Xiao Lei together, pointed to the mutilated corpse on the splint and said, "If you take a closer look, the clothes this person is wearing and other characteristics, can you tell who he is?"

"Yes...... It's Liu Biao. Xiao Gang's face turned pale, but he was very sure: "I recognize that dress, it was indeed worn by Liu Biao on the night of his disappearance." ”

"Are you sure?" Officer Wang hurriedly stepped forward.

Xiao Gang nodded silently: "It won't be wrong, the logo on the pants is the same, it should be Liu Biao." ”

The voice fell, and the scene suddenly fell silent.

Everyone froze there.

After getting Xiao Gang's confirmation, Gu Chen felt even more that things were definitely not so simple.

If you follow the known clues, it can basically be concluded that Liu Biao, who even wears shoes when he sleeps, seems to be being chased that night.

Then he broke the window and fled, driving the boat into the lake?

Of course, this is only Gu Chen's first speculation, this kind of active escape, in the center of the lake due to improper operation caused by falling into the water and dying.

But Gu Chen has another speculation, that is, after Liu Biao was killed, he abandoned the boat in the lake, and then the murderer destroyed the boat, creating a false impression that Liu Biao was wrecked in the boat.

But in either case, why Liu Biao fled is the key.

"Senior Brother Gu. Lu Weiwei, who was in a state of some reply, took the initiative to step forward and ask, "What to do with the corpse?"

"Bring it up. Gu Chen glanced at the mutilated corpse.

Obviously, to carry this body to the shore without destroying it twice, it is obvious that one person cannot operate it at all.

Gu Chen turned his head to look at Xiao Lei and said, "Manager Xiao, please ask a few people to carry the body ashore with me." ”

"No problem. Xiao Lei agreed very happily, and then glanced at several male waiters beside him and said, "A few of you, help the police comrades carry the corpse." ”

"I'm not going, it's disgusting. ”

"yes, the head is gone, it's terrifying. ”

"Whoever likes to go, I won't go anyway. ”

"Hey!"

Seeing that everyone under his command was retreating one by one, Xiao Lei was furious, and also urged: "You can't do such a thing, what use do you say? ”

"Manager. ”

Seeing that Xiao Lei was not ashamed, a tall and thin male waiter said: "Since you are a big man, then you can go and help the police comrades carry the corpse." ”

"yes, there you go. ”

"Manager, you should take the lead. ”

Seeing that the style of painting changed so quickly, Xiao Lei was also unexpected.

Just wanted to use his sprained waist as an excuse, but Gu Chen put it on Xiao Lei's shoulder.

"Manager Xiao, it seems that I can only bother you, put this on. Gu Chen handed him a pair of white gloves.

"Oh no, I'm ...... I'm ...... waist."

"If you want to act, hurry up. Before Xiao Lei could finish speaking, Officer Wang drove the ducks to the shelves and directly pushed Xiao Lei to the side of the boat.

General Gu Chen and Officer Wang had already boarded the boat, and the subordinates behind were staring at him, Xiao Lei was a little difficult to ride a tiger, so he could only agree stubbornly:

"Okay, okay, I'll give you a hand, isn't it just a corpse, what's the big deal?"

Five minutes later......

When the body was laid flat on the stone bricks of the pier, Xiao Lei squatted aside, vomiting and almost prostrating.

"Are you okay, Manager Xiao?" Gu Chen turned his head to ask Xiao Lei, who had collapsed behind him, after cleaning up some of the aquatic plants on the corpse.

"Carrying...... I can bear it, I don't have a problem, I vomit ......"

When the words fell, Xiao Lei vomited again, and the whole air was instantly filled with a sour taste.

Everyone on the side of the road pinched their noses and retreated, feeling that they should keep a distance from Xiao Lei.

Officer Wang walked up to Gu Chen, pointed to the headless corpse and said, "This Liu Biao is really unlucky, he doesn't even have a corpse after death, what are you raising in this Yangtian Lake?"

"It may be the doom of the blood on Liu Biao's body, it may be that he was killed and then thrown into the water, but now that the head is gone, and the corpse is gradually decomposing, if you want to know the answer, you can only do a diatom test.

"Diatom test?" Lu Weiwei said when she heard this, and she didn't know why: "But what is a diatom?"

Gu Chen glanced at Lu Weiwei, and also explained seriously: "This diatom is a kind of single-celled plant with pigments, from small puddles formed by rainwater to oceans that account for 71% of the earth's surface, almost all traces of diatoms can be seen, and there are more than 16,000 species of diatoms in the world. ”

"So many?" Lu Weiwei looked at the aquatic plants on the corpse and couldn't help but say, "I see, but why do you want to do a diatom test?"

"Didn't I just say that diatoms are single-celled algae. Gu Chen looked at Lu Weiwei's studious attitude, and patiently explained:

"If they are present in the corpse and are the same as diatoms in the water, then they can tell us whether the deceased entered the water while they were alive or after they were already dead. ”

"With this test, they can tell us if he died by drowning, which is very important for cadaver detection, especially with this mutilated body. ”

Lu Weiwei nodded as if she was pecking rice: "It seems to understand, I feel that Liu's forensic team should be familiar with this kind of test." ”

Glancing at Gu Chen, Lu Weiwei suddenly smiled and said, "But what Senior Brother Gu has learned is really extensive enough. ”

"It's okay. Gu Chen smiled and said, "The main thing is that the forensic transcript given to me by Forensic Doctor Liu is of great help. ”

"It's also a learning process, so I store this knowledge in my memory bank and apply what I've learned. ”

"That's true, Senior Brother Gu has never disappointed. "Lu Weiwei has always been Gu Chen's little fan sister.

Especially Gu Chen's strong learning ability, Lu Weiwei can always benefit a lot.

So Lu Weiwei continued to ask with a humble learning attitude: "But how can this diatom test be conducted?"

"A section of the corpse's femur needs to be taken for testing. Gu Chen said.

"Take a femur?" Lu Weiwei felt a little interesting, and said with a smile: "Then how much is appropriate?"

Gu Chen shook his head and smiled: "I'm not familiar with this either, after all, I only know the principle, but I haven't seen the actual operation." ”

"If you ask me how long a piece of bone is needed for this test, I don't know, and if I were to do it, I'd worry that I'd take too much or too little bone. ”

"What's there to worry about?" Officer Wang, who was standing on the side, couldn't help but complain: "I'll tell you what to do, anyway, there's nothing left on this guy." ”

"If it were me, I'd give you both of his complete femurs, and you can take as many as you want. ”

"Do you think that Lao Wang, who sells meat, has to extract it scientifically, be rigorous, don't talk nonsense if you don't understand. "Lu Weiwei hates Officer Wang's blindness.

I feel that Officer Wang doesn't know how to pretend to understand.

Even a scholar like Gu Chen, who knew the principle, did not dare to jump to conclusions without practical operation.

Lao Wang is good, and his mouth is full of fragrance.

Officer Wang said indifferently: "Actually, it's all the same, but you take the issue too seriously." ”

Several people had some minor disputes during the discussion of extracting the femur.

"Alright. Gu Chen interrupted the conversation of several people, and then said to Lu Weiwei: "Senior Sister Lu, please take a picture of the corpse." ”

"Oh, no problem. Lu Weiwei almost forgot to take pictures for evidence.

Although a few pictures of the scene were taken on the boat, the light was not good at that time, and the water and weeds were entangled, so it was difficult to see the specific situation of the body.

However, Lu Weiwei took the opportunity to take a lot of photos of Gu Chen wearing only pants.

When I came to the shore, under the light of the street lamp, the specific situation of the corpse was much clearer than before.

Lu Weiwei began to collect various evidences on the corpse from different angles.

While taking pictures, Lu Weiwei's mouth has not been idle, and she keeps thinking about it:

"It's all rotten like this, and the only thing that can make you speak again is diatom detection technology. ”

"Diatom detection, is this thing reliable?" Ding Liang came over and asked after washing his hands with mineral water with the assistance of Huang Zunlong.

Gu Chen nodded slightly: "A corpse in water, especially a highly decomposed corpse, how can you tell whether the deceased is drowned, or if the body was thrown into the water after death, and where did it enter the water from?"

"In fact, these detection technologies have been studied by a scientific research team for a long time. ”

"In particular, the Yangcheng Institute of Criminal Science and Technology, that is, the Institute of Criminal Science, this topic has always been the research direction of their forensic team. ”

Looking at everyone's serious looks, Gu Chen also took the opportunity to explain the situation to everyone clearly.

"In fact, a few years ago, when the annual National Science and Technology Award Conference was held in Beijing, the project of 'Key Technology and Equipment for Forensic Diatom Testing' of Yangcheng Criminal Science Institute won the second prize of National Science and Technology Progress Award. ”

And a few years earlier, it was also the project that won the first prize of the annual Ministry of Public Security Science and Technology Award. ”

"It is this kind of technology that can focus on actual combat and let the corpse 'speak', which can be said to be a great technological progress. ”

When Officer Wang heard this, he also recalled thoughtfully: "Gu Chen, what you said, I seem to have seen an internal report a few years ago. ”

"Yes, when I was at the police academy a few years ago, I also heard my instructor explain this technique, because he is from Yangcheng. ”

"And I heard that I have several seniors who are engaged in forensic work, and they all use the key technologies and equipment of forensic diatom testing from the Yangcheng Criminal Department to help them solve the big problems encountered in the investigation. ”

"So if you go to the criminal department in Yangcheng City, you will find that their walls are full of pennants from public security organs from all over the country. ”

"And these pennants were specially sent by the forensic doctors of the institute after using diatom testing technology to help them solve the problems encountered in the investigation. ”

Huang Zunlong, who had taken off his gloves, also said thoughtfully: "This technique is really so powerful? If the corpse is found in the lake water, and the corpse has completely decomposed into white bones, how can you detect this situation?"

"Surely it can't be detected, is it? It's all rotten to bones? How can this be detected? When Lu Weiwei heard this, she also had the same question.

Gu Chen hesitated for a few seconds, and then he used his specialization-level memory to quickly activate his brain.

A few seconds later, Gu Chen said indifferently: "Actually, in May 4 years ago, there was really such a case. ”

"At that time, it was a male corpse, which was found in a pond deep in the mountains of Hubei Province, and the corpse at that time, as Huang Zunlong said, had completely decomposed into white bones. ”

Later, after DNA comparison, it was revealed that the man was a beekeeper who set off for the mountains to collect honey that year, and then disappeared. ”

But when the missing person was found, they were confronted with a white skeleton. ”

"And how do you determine the cause of his death?" asked Lu Weiwei.

Gu Chen smiled indifferently: "Of course, it will be handed over to the forensic doctors of the Yangcheng Criminal Department to solve it, after all, they are professional in this regard." ”

After a pause, seeing that everyone was unclear, Gu Chen said again: "Because at that time, the corpse was only white bones, and there was no body tissue to extract." ”

"Therefore, this case, if the traditional diatom testing technology is used, it is completely impossible to detect. ”

"So what?" asked Ding Liang.

Therefore, the Yangcheng Criminal Science Institute used their innovative research and development of diatom detection technology, and finally succeeded in detecting the existence of diatoms in the bone marrow of the white bones of the corpse. ”

"And after comparison, this is consistent with the diatoms found in the pond where the body was found, so it can be determined that this person is drowning. ”

Just as Gu Chen was explaining, a few lights suddenly shone in the distance.

Gu Chen blocked the light with his hand, then stood up and took a closer look, and found that it was a group of figures in white coats approaching.

"Is it Forensic Doctor Liu?" Gu Chen shouted loudly.

Soon, Forensic Doctor Liu's response also came from the other side: "That's right, it's me." ”

"Gu Chen, when I received a call at night, I knew that it was the three of you who were looking for me. Another figure beside Forensic Doctor Liu, Gu Chen heard the complaints of forensic assistant Gao Chuanfeng.
