When we brought the body back to the Technical Section of the Municipal Bureau, it was already 6pm.
Everyone didn't have dinner, so Gao Chuanfeng brought everyone some food from the cafeteria.
In the evening everyone will have a great time in the newly established "interdisciplinary team" laboratory.
The so-called "interdisciplinary team" laboratory is actually a public laboratory platform for the common use of talents from various major disciplines in the police force.
Because it is a newly established laboratory, the equipment is not very complete. In the eyes of Forensic Doctor Liu, he still regards it as his own laboratory 1.
Of course, as a member of the interdisciplinary team, Gu Chen now has practical authority and can complete some less complex testing operations with the assistance of forensic assistant Gao Chuanfeng.
They saw Officer Wang and Lu Weiwei devouring their dinner, while Gu Chen walked into the laboratory with a camera and stood in front of the body to observe for a long time.
Gao Chuanfeng couldn't help but exclaimed: "Gu Chen doesn't want to have dinner?"
"Maybe he would rather let the corpse talk than eat dinner." Officer Wang glanced at Gu Chen in the laboratory and felt that this was Gu Chen.
Of course Gu Chen also has his own ideas...
After all, being able to join an interdisciplinary team actually allows you to have some practical opportunities with the help of the laboratory platform.
Compared with the past, Gu Chen could only be a bystander beside the forensic team, but now it is different. Now he is a participant.
At least it feels like this is a set of practice plans tailor-made for him by Forensic Doctor Liu.
Gu Chen, who was wearing protective clothing, turned on the camera, then walked around the woman's body.
"The deceased was electrocuted, but why did he suffer from suffocation symptoms?" Gu Chen put on gloves and repeatedly checked the woman's facial features.
At some unknown time, forensic doctor Liu, who had finished dinner, also wore a protective suit and walked gently to Gu Chen's side.
"How about it, Gu Chen, you've been here for a long time, have you discovered anything?" Forensic Doctor Liu asked.
Gu Chen nodded slightly and said: "When the deceased was found, the caller said he was electrocuted. Judging from the physical characteristics, he did have the characteristics of being electrocuted."
Glancing at Forensic Doctor Liu beside him, Gu Chen added: "But, I also discovered some characteristics of the deceased who died of suffocation."
"Death by suffocation?" Forensic Doctor Liu frowned slightly and asked curiously: "Tell me about it."
"Yeah." Gu Chen took a step forward, gently turned the deceased's head to the side with both hands, and said:
"Suffocation usually leaves various clues, such as the conjunctiva, which is the pink tissue around the eyeball, and spots of congestion."
"This condition is common in strangulation, but asphyxia may also occur. The mechanism is that when the victim struggles to breathe, the intravascular pressure will increase, causing the capillaries to rupture and bleed."
"Yeah." After hearing Gu Chen's explanation, Forensic Doctor Liu stepped forward to examine the corpse, and found that the symptoms Gu Chen mentioned were indeed present, so he added, "Keep talking."
Gu Chen nodded slightly and said calmly: "Because the capillaries rupture and bleed, the resulting subcutaneous ecchymoses look like tiny red spots or stripes."
"But petechiae may or may not appear."
"In addition, in order to make the victim asphyxiate, you must cover her face with something forcefully. This will cause bruises on the face and mouth of the deceased, as well as abrasions on the inside of her lips."
"Abrasion on the inside of the lip?" Forensic Doctor Liu raised his eyebrows.
Gu Chen continued to explain: "It's because the teeth are stressed against the tissue."
"Oh, yes, if that's the case, this will indeed happen."
Having said this, Forensic Doctor Liu gently opened the woman's lips and used the operating light to examine the condition inside the woman's lips.
After discovering that the woman did have abrasions inside her lip, Forensic Doctor Liu frowned slightly, then turned to Gu Chen and said: "Gu Chen, you are indeed observing carefully. You can even detect it from such a tricky angle."
"Because I feel that she died of suffocation. If it was the murderer, this should be the case. These are all written in the forensic manual." Gu Chen said.
"Yes, this is indeed the case." Forensic Doctor Liu admired Gu Chen's knowledge coverage very much, especially his comprehensive examination of corpses.
The reason why Gu Chen was allowed to join the interdisciplinary team was actually that Forensic Doctor Liu also had selfish motives.
Even if Zhao Guozhi doesn't let him go, he can still use the guise of this interdisciplinary team to get Gu Chen to come to him so that he can give him more guidance.
You know, Dr. Liu never likes to have apprentices, or he has extremely strict requirements for his apprentices.
But Forensic Doctor Liu also cherishes non-forensic talents like Gu Chen.
Although they all belong to different units, Forensic Doctor Liu is still willing to give guidance to Gu Chen, so that Gu Chen can master the corpse detection technology possessed by forensic doctors while doing other work.
Especially the use of instrument testing...
In this regard, this is what Gu Chen lacks.
After Gu Chen saw forensic doctor Liu inspecting the corpse, he agreed with his statement, and then he added: "If our forensic doctors see these phenomena, we can also infer that the victim died of suffocation."
"But there are also traces of electric shock on her body." Forensic Doctor Liu stood up straight and said involuntarily.
Gu Chen nodded slightly: "Yes, but the problem with electric shock is the timing. When the human body is exposed to electric current and is injured, it will induce an inflammatory reaction."
"At the same time, white blood cells and mast cells will also flow into the injured area."
"If the victim's heart stops immediately after being electrocuted, the reaction may be very mild."
After a pause, Gu Chen added: "However, if the victim survives for several minutes, the reaction will be more obvious."
Forensic doctor Liu glanced at Gu Chen: "This requires a microscope to examine the tissue at the entry and exit points of the current. Only in this way can this phenomenon be seen."
"So, when the victim is dead, the body will not have an inflammatory reaction." Gu Chen said.
"Well, let's talk about this later." The microscope examination will take some time, but Forensic Doctor Liu was going to put these operations at the end, so he asked Gu Chen again:
This chapter is not over, please click on the next page to continue reading! "Besides these, where else can you find out that the deceased was electrocuted?"
"Also...the changes in skin color at the entry and exit points of the current also provide another clue."
Gu Chen untied the deceased's clothes and pointed at the top of the left chest of the corpse.
Forensic Doctor Liu walked over, took a look, and nodded slightly.
Afterwards, Gu Chen went to the feet of the corpse, pointed to the right calf of the corpse and said: "If a living body is electrocuted and dies, the skin color will become darker and bleed, and the appearance of the corpse after being electrocuted will be light yellow.
"
"The two parts just looked like the entry point and outflow point of the current. I estimate that the current entry point is above her left chest, and the outflow point is at the right calf."
"Yeah." Forensic Doctor Liu nodded slightly, and he actually saw it.
But 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 I reviewed for Gu Chen, but among the many data, it is still quite difficult to imprint this knowledge in my mind.
But Gu Chen is different. This guy seems to be born with excellent memory ability, which allows Gu Chen to apply what he has learned from a large amount of knowledge reserves.
When he saw the summary in the forensic manual, he could make a quick and accurate detection judgment immediately.
In this regard, Forensic Doctor Liu did not dare to say that he could beat Gu Chen.
Seeing that Forensic Doctor Liu was silent, Gu Chen thought he was acquiescing to his test results, so he added:
"If we find that the skin color of the deceased is light yellow but there is no inflammatory reaction, we can conclude that the victim was electrocuted after death."
"If the skin color of the deceased becomes darker and there is an inflammatory reaction, then we can know that the victim was still alive when he was electrocuted."
"According to the time of death of the deceased, the electric current did not pass through the victim's body until 48 hours after his death. When we see this situation, we can determine that the electric shock occurred after death."
After Gu Chen expressed his opinion, he still saw that Forensic Doctor Liu remained silent. Gu Chen suddenly wondered: "What's wrong with Forensic Doctor Liu? Am I right?"
"Yes, that's so right, how could it be wrong?" Forensic Doctor Liu also laughed, gave a thumbs up to Gu Chen and said: "It seems that you, Gu Chen, have put into practice everything I gave you. Not bad.
."
In fact, it's not that Forensic Liu doesn't want to talk, it's just that he hasn't kept up with Gu Chen's rhythm.
Every time Gu Chen talks about an investigation, Forensic Doctor Liu will verify what Gu Chen said based on the condition of the corpse.
But Gu Chen's thinking was too fast, so before Forensic Doctor Liu completed the last test on the corpse, Gu Chen extended it to the next test.
For a moment, he was dragged away by Gu Chen, and he was too embarrassed to speak.
However, after repeatedly verifying the corpse several times, forensic doctor Liu was basically certain that the corpse was indeed what Gu Chen said.
After bowing and standing up, Forensic Doctor Liu asked Gu Chen: "So what is your judgment?"
"In my judgment, the deceased was most likely suffocated to death and then moved into the cold room by the murderer, who then electrocuted the deceased."
"The murderer's purpose in doing this was nothing more than to deliberately set up a suspicious formation to cover up his murderous crime."
"Although it is difficult to determine whether electric shock burns were caused before or after death, this is actually not a big problem for our inspectors. We can still verify it through other methods."
"Yes, you are right." Seeing that Gu Chen had already conducted a comprehensive examination on the body, Forensic Doctor Liu breathed a sigh of relief and said:
"Record all the things you just mentioned. I will help you do a microscope examination later and provide you with specific test data."
Glancing outside the door, Forensic Doctor Liu said again: "Now, is it time for you to go have dinner? After all, people are like iron rice and steel. If you don't eat, the food will be cold."
"Okay, I also want to find out the cause of death of the deceased as soon as possible. It doesn't matter whether he eats or not." Gu Chen actually wanted to find out the situation as quickly as possible.
But now that the situation is clear, and forensic doctor Liu is assisting in the microscope examination, Gu Chen feels that he has no worries.
Forensic Doctor Liu also said helplessly: "I think your workaholic problem should be corrected. You actually used the time before eating to do the testing work in such detail. Gao Chuanfeng will be hit hard by this.
"
"Is it so serious?" Gu Chen was also stunned. He didn't expect that he could bring a blow to others by working normally.
After thinking about it, he quickly said: "Then I'm going to eat now, and I will continue to investigate the situation of the deceased in the evening."
"Well, go ahead and leave this to me," Forensic Doctor Liu said.
After leaving the laboratory, Gu Chen changed out of his protective clothing, Lu Weiwei, Officer Wang and Gao Chuanfeng, and then prepared to enter the laboratory.
Seeing Gu Chen come out, Lu Weiwei hurriedly ran back, brought Gu Chen's food in front of her and said, "Junior brother Gu, eat quickly. The food is still a bit hot. If you don't eat, it will be cold."
"Okay, I'm just about 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. Examining corpses is a very tedious and time-consuming task. If you ask me, you might as well finish your dinner first and do this later."
Glancing at Forensic Doctor Liu in the laboratory, Gao Chuanfeng added: "Besides, this is what my master and I are doing. In fact, Gu Chen can do it without you, so leave the testing to me.
, I’ll do it for you.”
"But I have completed the autopsy." Gu Chen said this directly while eating the delicious dishes.
Gao Chuanfeng's smile gradually disappeared, and he asked blankly: "What did you say? Have you completed the test?"
"Yeah." Gu Chen nodded slightly while holding the food in his mouth.
"Haha." Gao Chuanfeng laughed twice and couldn't help but complain: "Not long after you, Gu Chen, entered the laboratory, you started bragging? After you finished the test, what is my master, Forensic Doctor Liu, still doing there?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "He is helping me clear the data." Gu Chen said.
Gao Chuanfeng was stunned again and didn't say anything more, so he turned around and went to the laboratory.
Lu Weiwei and Officer Wang looked at each other and asked Gu Chen: "Junior Brother Gu, do we still want to go in?"
"No need, right? You won't be able to help me much if I go. Just leave these clean-up tasks to Forensic Doctor Liu." Gu Chen ate very quickly and raced against every second. He quickly packed the empty lunch boxes in plastic bags.
, getting ready to throw it into the trash can at the door.
But just as he reached the door, Gao Chuanfeng walked out again.
Officer Wang was stunned and immediately asked Gao Chuanfeng: "Why did you come out again?"
Gao Chuanfeng gave a wry smile and said: "It's just some finishing work. I don't need to go in anymore."
"Pfft." After hearing Gao Chuanfeng's words, Lu Weiwei couldn't help but joked: "If I had known, you shouldn't have chatted with us just now. You should have followed Dr. Liu in first."
"That's all." Gao Chuanfeng leaned against the corner and said helplessly: "Anyway, as long as Gu Chen is here, I will become more and more relaxed, and I feel like nothing is wrong with me."
Looking down at his watch, Gao Chuanfeng asked again: "But Gu Chen, why do you detect so fast?"
"Perhaps we should thank the forensic transcript." Gu Chen took the single police equipment from Lu Weiwei and then said: "We have to go back to Furong Branch first. If there is any new situation, remember to call and notify."
"Also, when will the test report be ready and when will it be sent to me? That's it for now."
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 quickly followed Gu Chen's footsteps and left the experimental area.
Looking at the cheerful backs of the three of them, forensic assistant Gao Chuanfeng couldn't laugh or cry: "Come here with you, just to cheat me out of a meal? Not even saying 'thank you'?"
…
…
Time passes minute by minute.
At this moment, Gu Chen, Officer Wang and Lu Weiwei have arrived at the dispatch room of Furong Branch.
Looking at the repeatedly switching scenes on the screen, Gu Chen fell into deep thought.
Lu Weiwei asked Gu Chen: "Junior Brother Gu, do you really think the cause of this woman's death is strange?"
"That's right." Gu Chen looked at the screen visually and continued: "Judging from the corpse examination, there are indeed many problems. For example, she had symptoms of suffocation and death. In this case, the possibility of death by electric shock will be
Big discount.”
"Is there any possibility of her being electrocuted?" Officer Wang also asked.
"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, it seems more like she was suffocated to death and then touched with electricity to create a confusing illusion."
"That means that the deceased was most likely killed and then placed in the refrigerator?" Lu Weiwei's body trembled slightly when she thought of this.
I feel that if it is true, then this murderer really has good intentions.
At this moment, the trainee policeman in charge of the surveillance said: "Senior Brother Gu, the surveillance in the factory area seems to be a blind spot these days, and there are signs of damage. Only one area at the intersection is still intact, but the equipment is relatively old, and nothing too big can be found.
question."
"Huh, I knew the murderer wouldn't be so stupid." Gu Chen also took a deep breath, then pointed to his note paper and said: "You can call up this surveillance again and take a look at the industrial park and this building the day before yesterday.
Factory, this person."
The other person Gu Chen mentioned who was electrocuted was the woman's friend.
The day before yesterday, he was electrocuted in the factory just like the woman.
Although the family of the deceased did not call the police, Gu Chen decided to investigate after contacting the strange reason why the woman was electrocuted.
The trainee policeman nodded and then began to operate quickly.
But after some searching, nothing was found.
The trainee police officer also wondered: "It's strange, this industrial zone also has no surveillance in these key areas."
"No?" Lu Weiwei was stunned and turned to look at Gu Chen: "Sure enough, Junior Brother Gu, your guess is right. This matter is definitely not that simple."
Officer Wang also hurriedly said: "If it is really what you Gu Chen said, then we really have to go to the unit where the man was injured and injured due to electric shock the day before yesterday to see what the situation is like there, and maybe we can also 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 electrocution situation is like on the other side."
"In addition, let Senior Brother He find out the situation of these two deceased people as soon as possible and see where they have been recently? Who have they been in contact with?"
