It was already 6 p.m. when the body was brought back to the technical section of the city bureau.

Everyone didn't eat dinner, so Takakawa Kaede brought some food from the cafeteria.

In the evening, everyone had to work in the newly formed "interdisciplinary team" lab.

The so-called "interdisciplinary team" laboratory is actually a public laboratory platform for the joint use of talents from various disciplines of the Force.

Because it is a newly established laboratory, the equipment is not too complete, and in the eyes of Forensic Doctor Liu, he still regards it as his own laboratory +1.

Of course, Gu Chen, as a member of the interdisciplinary team, now has practical powers, and can complete some less complicated testing operations together with the assistance of forensic assistant Gao Chuanfeng.

Seeing that Officer Wang and Lu Weiwei were eating dinner with gusto, Gu Chen walked into the laboratory with a video camera, and stood in front of the corpse for a long time.

Gao Chuanfeng couldn't help but say, "Doesn't Gu Chen eat dinner?"

"Maybe he'd rather let the corpse do the talking than dinner. Officer Wang glanced at Gu Chen in the laboratory, feeling that this was Gu Chen.

Of course, Gu Chen also has his own ideas......

After all, being able to join the Kua discipline team is actually to allow yourself to have some practical opportunities with the help of the laboratory platform.

Compared with the past, Gu Chen could only be a bystander by the side of the forensic team, but now he is different, and now he is a participant.

At least I feel that this is a set of practice plans tailored by Forensic Doctor Liu for himself.

Gu Chen, who was wearing protective clothing, turned on the camera, and then walked to the woman's body and walked around.

"The deceased was electrocuted, but why did the symptoms of suffocation appear?" Gu Chen wore gloves and repeatedly checked the woman's facial features.

I don't know when, Forensic Doctor Liu, who had eaten dinner, also wore a set of protective clothing and walked gently to Gu Chen's side.

"How about Gu Chen, seeing that you have been here for a long time, have you found anything?" asked Forensic Doctor Liu.

Gu Chen nodded slightly and said, "When the deceased was found, the police said that he was electrocuted, and judging from his physical characteristics, he did have the characteristics of electrocution. ”

Glancing at Forensic Doctor Liu beside him, Gu Chen said again: "However, I also found some characteristics of the deceased who died of suffocation. ”

"Suffocation to death?" Forensic Doctor Liu frowned slightly, and asked curiously, "Tell me about it." ”

"Hmm. Gu Chen stepped forward, gently turned the deceased's head to the side with both hands, and said:

"Asphyxia usually leaves clues like the conjunctiva, which is the pink tissue around the eyeball, which is punctate bruising. ”

"This condition is common in strangulation, but ventricular breath can also occur by the mechanism that when the victim struggles to breathe, the intravascular pressure increases, causing the microvessels to rupture and bleed. ”

"Hmm. Hearing Gu Chen's explanation, Forensic Doctor Liu stepped forward to test the corpse, and indeed had the symptoms that Gu Chen said, so he said, "You go on." ”

Gu Chen nodded slightly, and said lightly: "Because the microvessels ruptured and bleed, the subcutaneous ecchymosis produced looks like tiny red spots or streaks. ”

"But ecchymosis may or may not occur. ”

"In addition, in order for the victim to rest, it is necessary to cover her face with something forcefully, which will cause bruises on the deceased's face and mouth, as well as abrasions on the inside of the lips. ”

"Abrasions on the inside of the lips?" forensic doctor Liu raised his eyebrows.

Gu Chen continued to explain: "It's because the teeth are pressed against the tissue. ”

"Oh, yes, if so, that's the case. ”

Speaking of this, Forensic Doctor Liu gently opened the woman's lips and used the illumination of the surgical light to check the situation in the woman's lips.

When he found that the woman did have abrasions in her lips, Forensic Doctor Liu frowned slightly, and then turned his head to Gu Chen and said, "Gu Chen, you have observed it carefully, and you can even find such a tricky angle." ”

"Because I feel like she died of suffocation, and if the killer did it, that would have happened, which is written in the forensic manual. ”

"Yes, that's true. Forensic Doctor Liu appreciated Gu Chen's knowledge coverage very much, especially the examination of the corpse, which was comprehensive.

The reason why Gu Chen joined the interdisciplinary team was that Forensic Liu was also selfish.

Even if Zhao Guozhi doesn't let people go, he can let Gu Chen come to his side under the guise of this interdisciplinary team, so that he can give him more guidance.

You must know that Forensic Doctor Liu has never liked to take apprentices, or he has extremely strict requirements for apprentices.

But for a non-medical talent like Gu Chen, Forensic Liu also cherishes it very much.

Although everyone belongs to different units, Forensic Doctor Liu is still willing to guide Gu Chen, so that Gu Chen can master the corpse detection technology possessed by forensic doctors while doing other work.

In particular, the use of instruments to test ......

This is also what Gu Chen lacks.

After Gu Chen saw Forensic Doctor Liu examining the corpse, he agreed with his statement, and then he said: "If our forensic doctor sees these phenomena, we can also deduce that the victim died of suffocation. ”

But she also had traces of electric shocks. Forensic Doctor Liu stood up straight and couldn't help but say.

Gu Chen nodded slightly: "That's right, but the problem with electric shock is timing, when the human body is injured by contact with electric current, it will induce an inflammatory reaction." ”

"At the same time, white blood cells and mast cells will also flood into the injured area. ”

"If the victim's heartbeat stops immediately after being electrocuted, the reaction may be very mild. ”

After a pause, Gu Chen said again: "However, if the victim survives for a few minutes, then the reaction will be more obvious." ”

Forensic Doctor Liu glanced at Gu Chen: "This requires a microscope to examine the tissues at the point of entry and outflow of the current, and only then can this phenomenon be seen." ”

"So, when the victim is dead, the body does not have an inflammatory response. ”

"Well, we'll talk about that later. It will take some time for the microscope to be examined, but Forensic Doctor Liu was ready to put these at the end to operate, so he asked Gu Chen again:

"Besides these, where else can you find out that the deceased was electrocuted?"

"And then there'...... The change in skin color at the point of entry and outflow of the current also provides another clue. ”

Gu Chen untied the deceased's clothes and pointed to the top of the corpse's left chest.

Forensic Doctor Liu walked over and looked at him twice and nodded slightly.

Then, Gu Chen came to the position of the corpse's feet again, pointed to the position of the corpse's right calf and said: "If it is a living body electrocuted to death, then the skin color will become darker and bleeding, and the corpse will be electrocuted, and the appearance will be pale yellow." ”

"And just now, these two parts look like the current entry point and the reservation point, I estimate that the current entry point is above her left chest, and the flow point is at the right calf position. ”

"Hmm. Forensic Doctor Liu nodded slightly, he actually saw it.

It's just that what I didn't expect was that Gu Chen even knew this?

You must know that it is indeed mentioned in the forensic manual that you reviewed for Gu Chen, but among the many data and data, it is still quite difficult to imprint this knowledge in your mind.

But Gu Chen is different, this guy seems to be born with excellent memory ability, which can allow Gu Chen to apply what he has learned in a large amount of knowledge reserves.

When he saw the summary in the forensic manual, he was able to make a quick and accurate detection judgment at the first time.

In this regard, Forensic Doctor Liu didn't dare to say that he could beat Gu Chen.

Seeing that Forensic Doctor Liu didn't speak, Gu Chen thought that he was acquiescing to his test results, so he said:

"If we find that the deceased's skin is pale yellow, but there is no inflammation, then we can conclude that the victim was electrocuted after death. ”

"If the deceased's skin tone is darker and there is inflammation, then we know that the victim was still alive at the time of the shock. ”

"According to the time of the deceased's death, the electric current passed through the body 48 hours after the victim's death, and when we see this situation, we can conclude that the electric shock occurred after the death. ”

After Gu Chen expressed his opinion, he still saw that Forensic Doctor Liu was silent, and Gu Chen suddenly wondered: "What's the matter, Forensic Doctor Liu?

"Yes, that's right, how could it be wrong?" Forensic Doctor Liu also smiled, gave Gu Chen a thumbs up and said, "It seems that you Gu Chen have applied all the things I gave you to you, which is good." ”

In fact, Forensic Doctor Liu didn't want to speak, but he hadn't kept up with Gu Chen's rhythm yet.

Every time Gu Chen said about an investigation, Forensic Doctor Liu had to verify what Gu Chen said based on the condition of the corpse.

But Gu Chen's thinking was too fast, so when Forensic Doctor Liu's last test on the corpse was not completed, Gu Chen extended to the next test.

For a while, Gu Chen was hung away, and he was embarrassed and speechless.

However, after repeatedly verifying the corpse several times, Forensic Doctor Liu can basically determine that the corpse is indeed as Gu Chen said.

Bowing up, Forensic Doctor Liu asked Gu Chen, "So what about your judgment?"

"In my judgment, it is very likely that the deceased was suffocated to death, and then moved into the cold room by the murderer, and then electrocuted the deceased. ”

"The murderer's purpose in doing this is nothing more than trying to deliberately set up a suspicion to cover up his murderous crime. ”

"Although it is difficult to determine whether the electric shock burn was caused before or after death, this is actually not a big problem for us inspectors, and we can still verify it through other methods. ”

"Yes, you're right. Seeing that Gu Chen had already conducted a comprehensive examination of the corpse, Forensic Doctor Liu breathed a sigh of relief and said:

"Record all these things you just had, and I will help you examine them as a microscope and provide you with specific test data. ”

Glancing out of the door, Forensic Doctor Liu said again: "Then now, shouldn't you go to dinner?" After all, people are iron and rice are steel, and if you don't eat, the food will be cold." ”

"Well, I also want to find out the cause of death of the deceased as soon as possible, it doesn't matter if I eat or not. "Gu Chen actually figured out the situation as quickly as possible.

But now that the situation is clear, and the microscopic examination has the help of Forensic Doctor Liu, Gu Chen feels that he has no worries.

Forensic Doctor Liu also said helplessly: "I think your workaholic's problem should be changed, you actually used this little time before dinner to meticulously carry out the testing work to such an extent, you will make Gao Chuanfeng suffer a blow." ”

"Is it so serious?" Gu Chen was also stunned, he didn't expect that he could bring a blow to others if he was working normally?

Thinking about it, he hurriedly said: "Then I will go to dinner now, and I will continue to investigate the situation of this deceased person in the evening." ”

"Well, go ahead, leave it to me here. Forensic doctor Liu said.

After leaving the laboratory, after Gu Chen changed into protective clothing, Lu Weiwei, Officer Wang and Gao Chuanfeng were ready to enter the laboratory.

Seeing Gu Chen come out, Lu Weiwei hurriedly trotted back again, brought Gu Chen's food to the front and said, "Senior Brother Gu, hurry up and eat, the food is still a little hot, and if you don't eat, it will be cold." ”

"Well, I'm getting ready to eat. Gu Chen took the lunch box from Lu Weiwei's hand and prepared to sit on the aisle seat to enjoy dinner.

Gao Chuanfeng also came over to comfort him: "Don't work so hard, testing the corpse is a very tedious thing, and it takes a lot of time, if you want me to say, you might as well come and do this after dinner first." ”

Glancing at Forensic Doctor Liu in the laboratory, Gao Chuanfeng said again: "Besides, this matter was originally something I did with my master, and it was not practical for you Gu Chen to operate it, so leave the testing to me, and I will complete it for you." ”

"But I've already done the autopsy. Gu Chen ate fragrant dishes, and came directly.

Gao Chuanfeng's smile gradually disappeared, and he was stunned and asked, "What did you say?"

"Hmm. Gu Chen took the food in his mouth and nodded slightly.

"Huh. Gao Chuanfeng laughed dryly, and couldn't help complaining: "You Gu Chen just entered the laboratory not long ago, and you started to brag?

"He's helping me clear my data. Gu Chen said.

Gao Chuan Feng was stunned for a moment, didn't say anything, and turned around and went directly to the laboratory.

Lu Weiwei and Officer Wang looked at each other and asked Gu Chen, "Senior Brother Gu, do we still want to go in?"

"No need, right? You can't help much, just leave these tail-cleaning tasks to Forensic Doctor Liu. Gu Chen ate very fast, and every second counted, and he quickly packed the empty lunch box in a plastic bag, ready to get up and throw it into the trash can at the door.

But as soon as he walked to the door, Gao Chuanfeng walked out again.

Officer Wang was stunned for a moment, and immediately asked Gao Chuanfeng, "Why did you come out again?"

Gao Chuanfeng smiled bitterly and said, "It's all some tail-clearing work, and I don't need to go in anymore." ”

"Poof. Hearing Gao Chuanfeng's words, Lu Weiwei couldn't help but joke: "I knew that you shouldn't have chatted with us just now, you should have followed Forensic Doctor Liu in first." ”

"That's it. Gao Chuanfeng leaned against the corner of the wall, and said helplessly: "Anyway, as long as Gu Chen is here, I will be more and more relaxed, and I feel that nothing is wrong with me." ”

Looking down at his watch, Gao Chuanfeng asked again, "But Gu Chen, how did you detect so fast?"

"I should probably be thankful for the forensic transcript. Gu Chen took over the single police equipment from Lu Weiwei, and then said: "We have to go back to the Furong Branch first, if there is any new situation, remember to call to inform us." ”

"Also, when the test report will be ready and when it will be sent to me, let's do it first. ”

Glancing at Lu Weiwei and Officer Wang beside him, Gu Chen said again: "Senior Sister Lu, Senior Brother Wang, let's go." ”

"Okay. ”

Lu Weiwei and Officer Wang both responded, and then hurriedly followed Gu Chen's footsteps and left the experimental area directly.

Looking at the backs of the three of them, forensic assistant Gao Chuanfeng couldn't cry or laugh: "Come here with you, just pit me for a meal?"

......

......

Minutes and seconds passed.

At this moment, Gu Chen, Officer Wang and Lu Weiwei had already come to take the dispatch room of the Furong Branch.

Looking at the camera images that switched repeatedly on the screen, Gu Chen fell into deep thought.

Lu Weiwei asked Gu Chen: "Senior Brother Gu, do you really think the cause of this woman's death is strange?"

"That's right. Gu Chen looked at the screen and continued: "Judging from the corpse detection, there are indeed many problems, such as the symptoms of her suffocation and death, in this case, the possibility of electrocution death will be reduced. ”

"Is there a chance that she will be electrocuted?" asked Officer Wang.

"Yes. Gu Chen nodded slightly, and said, "Of course there is, and it's obvious." ”

"But there is a problem, judging from the physical characteristics of the deceased, she is more like she was suffocated to death, and then touched by electricity to create a false impression of confusion. ”

"That is to say, it is very likely that this deceased person was killed and then put in the refrigerator?" Lu Weiwei thought of this, and her body trembled slightly.

I feel that if it is true, then this murderer is really well-intentioned.

At this moment, the trainee police officer who was in charge of the monitoring said: "Senior Brother Gu, the monitoring of the factory area seems to be a blind spot in the past few days, and there is damage to it, only one of the intersections is still well preserved, but the equipment is relatively old, and there is no big problem." ”

"Phew, I knew the murderer wouldn't be so stupid. Gu Chen also took a deep breath, so he pointed to his sticky note and said, "You can call up this monitoring again, and look at this industrial park, this factory, and this person the day before yesterday." ”

The other deceased who Gu Chen mentioned was a friend of the woman.

The day before yesterday, like the woman, he was electrocuted in the factory area.

Although the deceased's family did not call the police, when contacted by the strange news of the woman's electrocution death, Gu Chen still decided to investigate.

The mid-lieutenant asked with a nod, and then began to operate quickly.

But after some investigation and search, nothing was found.

The probationary police officer also wondered: "It's strange, this industrial area is also not monitored in these key areas. ”

"No?" Lu Weiwei was stunned and turned her head to look at Gu Chen: "Sure enough, Senior Brother Gu, your guess is right, this matter is definitely not so simple." ”

Officer Wang also hurriedly said: "If it is really what you Gu Chen said, then we really have to go to the men's unit where the electrocution was killed and injured the day before yesterday to see what the situation is on his side, and maybe we can investigate some clues." ”

"That's right. Gu Chen agreed with Officer Wang's opinion and said directly: "Without further ado, let's go over now and see what the electric shock situation is on the other end?"

"In addition, let Senior Brother He find out the situation of the two deceased people as soon as possible, and see where they have been recently, and who have they been in contact with?"

......
