A large wave of police and forensic doctors came in the evening, which made the Yangtian Lake Hotel, which is usually not very lively at night, lively all of a sudden.

Not only the staff, but also many customers who dined at the Yangtian Lake Hotel began to gather by the river.

So much so that Ding Liang and Huang Zunlong had to pull out another cordon to stop the melon-eating crowd outside.

"Forensic Doctor Liu, this is the corpse. Gu Chen stepped forward and introduced the scene to Forensic Doctor Liu.

Forensic Doctor Liu nodded slightly, and said to the forensic assistant Gao Chuanfeng: "Xiao Gao, take out the tools." ”

"Alas. When Gao Chuan Feng heard this, he quickly put a small suitcase on the ground, and after opening the lock, all kinds of precision utensils were neatly embedded in the foam cushion.

Forensic doctor Liu put on gloves and began to squat down to examine the body on the ground.

Gu Chen turned on the strong light flashlight and provided light assistance to Forensic Doctor Liu.

After a while, Forensic Doctor Liu frowned, stood up and couldn't help but say, "This corpse is seriously mutilated, and it has been soaked in the lake water for a long time, and many parts have decomposed. ”

"That's right. Gu Chen nodded slightly, and told him what he knew: "If you guessed correctly, this person should be Liu Biao, an employee of Yangtian Lake Hotel who disappeared a few days ago." ”

"At the moment, we are only salvaging the body in the lake, but it is not very clear whether Liu Biao drowned or was killed and thrown into the lake. ”

"Gu Chen, you're giving us a problem. Forensic assistant Gao Chuanfeng looked at the master's sad face and knew that it was very difficult to detect such a corpse.

Usually, if it is a complete corpse, Takakawa Kaede himself can go out and test the wounds of the deceased.

But now the body is mutilated, and it has been soaked in the lake for many days, and many of the wounds have been bitten by the aquarium in the lake.

The so-called wound marks have long been impossible to identify, and this is where the difficulty lies.

Forensic Doctor Liu glanced at Gao Chuanfeng and reminded: "The job responsibility of the forensic doctor is to restore the truth of the deceased, and they are all simple operations, so what's the challenge?

"Uh, master, I'...... I'll just talk about it. Knowing that Forensic Doctor Liu was teaching himself a lesson, Gao Chuanfeng immediately shut his mouth.

As a result, Lu Weiwei proposed: "Forensic Doctor Liu, I think we should do a diatom test as soon as possible, you see that this body is already like this, maybe it is very likely that he was killed and then thrown into Yangtian Lake." ”

"But now that his head is gone, and his body is decomposing, the only way to know the answer is to do a diatom test. ”

Lu Weiwei almost restored the rhetoric that Gu Chen introduced to everyone just now, but she shocked Forensic Doctor Liu beside her.

Forensic Doctor Liu stared at Lu Weiwei dumbfounded, and also said in astonishment: "Lu Weiwei, yes, you even know about the diatom test?"

Lu Weiwei smiled and said, "It's okay, isn't this the content of your forensic manual?"

Forensic assistant Gao Chuanfeng looked at the two of them and was stunned, and couldn't help but ask Forensic Doctor Liu: "Master, what is a diatom?

"So you have to study hard. Before Gao Chuanfeng finished speaking, Lu Weiwei directly and seamlessly said: "This diatom is actually a general term for a single-celled plant with pigments, from small puddles formed by rainwater accumulation, 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." ”

Lu Weiwei still copied Gu Chen's words just now, 1510.

But it was to bluff Forensic Doctor Liu and Gao Chuanfeng for a moment......

Gao Chuanfeng turned his head to look at Forensic Doctor Liu, and also asked weakly: "Master...... Master, is that really the case? This Lu Weiwei can't be nonsense, right? How could she know this?"

"What nonsense? That's right. Forensic Doctor Liu hated iron and said: "You should learn more from others, Lu Weiwei is not a forensic professional, and you don't know about diatom testing, so it's not a shame." ”

"Poof!"

Seeing that Gao Chuanfeng was beaten down by Forensic Doctor Liu, Ding Liang and Huang Zunlong, who had pretended to be calm before, couldn't help but laugh.

Lu Weiwei's eyes widened, and she immediately told the two to shut up.

Then he smiled at Forensic Doctor Liu and said, "Forensic Doctor Liu, I can work hard, and Senior Brother Gu usually asks me to study more." ”

"I think that the reason why Senior Brother Gu is so powerful is because of continuous learning, and with more knowledge, isn't it easy to apply what he has learned?"

Glancing at Gao Chuanfeng, Lu Weiwei teased, "Is that right?"

"Yes, yes, yes. Gao Chuanfeng was a little unhappy, feeling that Lu Weiwei, an amateur forensic doctor, had actually ridden on his head.

But because Forensic Doctor Liu was at the scene, he could only pretend to be ashamed and asked: "Then you can tell me, why do you want to do diatom testing, and what is the significance of diatom testing?"

When Lu Weiwei heard that she was sending a score question again, she directly pretended to think about it, and then walked around twice in front of Gao Chuanfeng, and suddenly said:

"By the way, I remember again that if these diatoms are present in the corpse and are the same as the 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. ”

Seeing that Forensic Doctor Liu on the side nodded slightly, and seemed to be puzzled, Lu Weiwei hurriedly said: "With this test, they can tell us whether the body was drowned or not, which is very important for corpse detection, especially this kind of incomplete corpse." ”

"Ahem. Seeing that Lu Weiwei was a little too dramatic, Officer Wang hurriedly coughed twice as a reminder.

Lu Weiwei comprehended, so she pretended to be distressed, and the scholar Gu Chen couldn't help but complain about what she said to herself just now:

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

"Not bad. "Forensic Doctor Liu really believes it.

To be able to explain these things so professionally, I am afraid that it cannot be said that ordinary schools can understand it, and this must require a lot of effort.

Otherwise, why hasn't his assistant Gao Chuanfeng been in contact with it? Because this latest diatom detection technology and equipment has only been out for a few years.

Compared with some previous diatom detection technologies, the accuracy is also greatly improved.

Forensic Doctor Liu really convinced Lu Weiwei, and felt that this Lu Weiwei was really impressed by the three days.

So Forensic Doctor Liu asked Lu Weiwei with the mentality of testing: "Lu Weiwei, then tell me how we should test." ”

"A section of the corpse's femur needs to be taken for testing. Lu Weiwei said with a serious face.

The voice fell, which completely made Forensic Doctor Liu excited.

hurriedly patted Lu Weiwei on the shoulder: "Weiwei, I really can't see it, the third criminal investigation team of your Furong Branch is really a hidden dragon and a crouching tiger." ”

"Even you know so much about diatom testing, it seems that I really underestimated you Lu Weiwei before. ”

"Hee-hee. When Lu Weiwei heard such praise, her heart was also happy.

Xin said that if it weren't for Gu Chen's explanation to himself just now, I am afraid that he would not know anything about diatom testing at all.

However, Lu Weiwei has her own unique advantages, that is, she has to ask Gu Chen about everything, and absorb knowledge and nutrition from Gu Chen to fill herself.

Fortunately, I just applied what I learned, and it was still okay to bluff an old-timer like Forensic Liu.

Seeing that Forensic Doctor Liu also seemed to agree with the need for diatom testing, Gu Chen hurriedly asked: "Forensic Doctor Liu, can the technical laboratory of our Municipal Bureau conduct diatom testing?" Or do you need to send it to Yangcheng for testing?"

"Gu Chen, do you also know about the diatom test in Yangcheng?" Forensic Doctor Liu looked at Gu Chen and couldn't help but smile and ask.

Gu Chen nodded: "I know some, then there is professional equipment there, and they have been studying diatom detection for many years." ”

"That's right, if you want to say that the most famous diatom test, it is really their Yangcheng Criminal Science Institute, this topic has always been the research direction of their forensic team. ”

Looking at everyone's serious looks, Forensic Doctor Liu said: "But it doesn't matter, we also have advanced testing equipment here, which can fully meet the conditions of diatom testing." ”

"That's great. When he heard that the technical department of the Municipal Bureau could also conduct diatom testing, Gu Chen was a little overjoyed.

As a result, the detection time can be significantly reduced.

Seeing that the situation was clear, Officer Wang also hurriedly urged: "Then let's not stay, hurry up and send the remains of the corpse to the technical department of the city bureau, if you can, the best result can be produced tonight." ”

"Tonight?" Hearing Officer Wang's remarks, the forensic assistant Gao Chuanfeng was a little big, and he was also not angry:

"My master has been working all day, and he has finished the work at hand in the evening and is ready to go home to rest, but as soon as he received a call from your old Wang, he rushed over non-stop. ”

"It's so urgent, I'm afraid that the master's body can't stand it, or tomorrow, right?"

"How can this be done? The investigation of the case is a matter of time. Seeing that the assistant Gao Chuanfeng wanted to buy a little rest time for himself, Forensic Doctor Liu directly refuted it.

"Also, I'm very physically tough, what's wrong with staying up late to work? I stayed up late at the beginning, and the workload you do now is several times higher. ”

Looking at everyone's expectant eyes, Forensic Doctor Liu also gritted his teeth and couldn't help but say: "Young people nowadays just can't endure hardship, alas." ”

"Or ...... According to what Gao Chuanfeng said, Forensic Doctor Liu, we will test again tomorrow, and you can rest well tonight. Gu Chen also gave Forensic Doctor Liu a step.

But Forensic Doctor Liu waved his hand and refused directly: "No need, just do the test tonight, everyone prepare, pack up this corpse, and bring it back to the Technical Department of the Municipal Bureau." ”

"No problem. Gu Chen nodded slightly, then looked at his colleague and said, "Everyone come over and help." ”

Following Forensic Doctor Liu's car, everyone prepared to return to the Technical Department of the Municipal Bureau together.

On the way back, Ding Liang drove, while Gu Chen sat in the back seat, in the temporary action group, listening to the reports of several other teams.

Gu Chen: [Close, we found Liu Biao's body, and now we are about to return to the Technical Department of the Municipal Bureau, what is the situation over there?]

It didn't take long for another team to appear in the dialog box, with a reply from Officer Zhou.

Zhou Xingxing: [Although we didn't find any suspicious equipment, we caught a few men and women who were doing wrong, and we were caught engaging in improper relationships, and we didn't find nothing this time. 】

As soon as Officer Zhou Xingxing's information from this group was issued, Officer Liao from the other team also sent a report.

Liao Zhenhua: [We didn't find any sniffing equipment here, but we caught a group of people who gathered D, and the amount of money involved was quite large, and we didn't find nothing. 】

Gu Chen: [Okay, these things are left to you to deal with, everyone has worked hard. (Fist hugging)】

Zhou Xingxing: [(Holding fists)]

Liao Zhenhua: [(Holding fists)]

Lu Weiwei: [(cute face)]

Lu Weiwei: [Everyone has worked hard, go back and ask Lao Wang to invite everyone to dinner. 】

Officer Wang: [(frightened)]

Officer Wang: [Why? Why did Gu Chen lead everyone to participate in the operation, and my old Wang was responsible for inviting guests to dinner? You can't pick one of them, right? (Hammerhead)】

Zhou Xingxing: [(snickering)]

Liao Zhenhua: [(snickering)]

Huang Zunlong: [Senior Sister Lu is so cute, Senior Sister Lu shines today, and she was praised by Forensic Doctor Liu. 】

Lu Weiwei: [(shy)]

Lu Weiwei: [Where is it, entrusting Senior Brother Gu Hongfu, following Senior Brother Gu is to lie down and win, hehe. 】

Officer Wang: [(Hammerhead)]

Zhou Xingxing: [(Two policemen laughing and laughing)]

......

......

Following Forensic Doctor Liu, everyone came to the Technical Department of the Municipal Bureau.

Soon, after the disinfection treatment, everyone followed Forensic Doctor Liu and Gao Chuanfeng to the laboratory.

Ding Liang and Huang Zunlong, the two sat in the lounge and waited patiently.

Gu Chen, Lu Weiwei and Officer Wang came to the laboratory together as observers, after putting on protective equipment.

After extracting the two femurs, the medical examiner Liu was highly skilled, and then began to move on to the next step.

Lu Weiwei was a little unaccustomed to seeing too bloody, so she could only turn her head to look at him.

Gu Chen and Officer Wang, on the other hand, were staring at the operation steps throughout the whole process.

Gao Chuanfeng, a forensic assistant on the side, also took the opportunity to ask for advice: "Master, do you think this little diatom can really become the gold standard for drowning diagnosis?"

"Then you still need to say?" Forensic Doctor Liu glanced at Gao Chuanfeng, and then looked at Gu Chen and Officer Wang behind him, and then couldn't help but say:

"Diatoms are actually very useful in diagnosing drowning deaths because of their small size and their widespread presence in a variety of waters, which makes them often inhaled and swallowed by the deceased in the water during drowning. ”

"They then accumulate through the bloodstream in different organs such as the lungs, brain and bone marrow. ”

Seeing that Gao Chuanfeng just nodded silently, and Gu Chen had already begun to take out a small notebook and record it.

Forensic Doctor Liu felt that his apprentice had lost another game, so he sighed and asked Gao Chuanfeng: "Then do you know what the shell of this diatom is made of?"

"Uh!" Gao Chuanfeng was stunned and turned his head to look at Gu Chen.

Gu Chen blurted out directly: "The shell of the diatom is composed of silica, and because of this, this composition is the same as sand. ”

"Hmm. Hearing Gu Chen's words, Forensic Doctor Liu nodded slightly, and continued to ask: "Gu Chen, tell me what you know." ”

"Yes. Seeing that Forensic Doctor Liu agreed, Gu Chen, who was afraid of disturbing Forensic Doctor Liu's examination at first, replied directly:

"Diatoms do not dissolve in strong acids, so as a tester, you can always use strong acids to digest the tissue and then extract the diatoms from the digestion solution. ”

"This can be viewed with a microscope, and the examiner can compare it to the diatoms in the water where the body was found. ”

"If no diatoms are found in the body, it means that the victim is not drowned, and if the diatoms found in the organs are significantly different from the diatoms found in the body of water where the body was found, it means ...... The victim drowned elsewhere. ”

After a pause, seeing that Forensic Doctor Liu had been listening carefully while waiting for the test, Gu Chen also continued to add:

"If this is the case, it is clear that there is a suspect who moved his body to a second location in order to create the illusion of an accident. ”

"Well said. Seeing that Gu Chen's performance was excellent and he almost understood this set of principles thoroughly, Forensic Doctor Liu couldn't help but admire:

"Gu Chen, your knowledge is indeed very extensive, I have to praise you for this. ”

"Thank you, Forensic Doctor Liu. Gu Chen was still very modest.

Forensic Doctor Liu waved his hand: "If the forensic doctors in the technical department of our municipal bureau can be as diligent as you, I want to train a few top forensic doctors, it should not be a big problem." ”

"But the problem is ......" Glancing at Gao Chuanfeng beside him, Forensic Doctor Liu shook his head and sighed: "But the problem is that there are many excellent forensic doctors, but there are very few top-notch ones." ”

"Forensic Doctor Gao is also considered to be a top-notch class, right?" Seeing Forensic Doctor Liu praising himself for a long time, he was not very satisfied with his assistant Gao Chuanfeng.

In order to balance Gao Chuanfeng's psychological gap, Gu Chen still deliberately mentioned Gao Chuanfeng.

But Forensic Doctor Liu didn't think so, and said with a low snort and a smile: "Gao Chuanfeng is quite good, but not top-notch, the kind of top-notch forensic doctor I am talking about, at least on the basis of excellence, can rely on his own talent to improve." ”

Glancing at Gu Chen, Forensic Doctor Liu sighed deliberately, shook his head and sighed: "If only there was an apprentice like you Gu Chen by my side." ”

"Haha, Forensic Doctor Liu, I think you're still dead in this heart. Officer Wang had already guessed what Forensic Doctor Liu meant, and couldn't help but joke: "Even if Gu Chen is willing to come to you, then can our Zhao Bureau agree? ”

"Haha. Lu Weiwei stood aside as a crowd of people eating melons, and she was also happy to see that Forensic Doctor Liu was eager to include Gu Chen under his command.

"Okay, okay, I'm just thinking about it, can't I think about it? My old Liu is not as blessed as him Zhao Guozhi in his life, hey. ”

After sighing, Forensic Doctor Liu continued to carry out the test, and said softly: "I want to be at the beginning, it is not easy to tackle this new technology, and the success rate of the old diatom detection is not high. ”

Glancing at Gu Chen behind him, Forensic Doctor Liu also said in his heart: "I also want to set up a team to conduct detailed training on the testing methods of my peers in Yangcheng." ”

"And this team must also be composed of the technical department, or the backbone members of the police force, I define this team as...... Interdisciplinary teams. ”
