I'm a Super Cop

Technology Department of Municipal Bureau, testing room.

Lu Weiwei's question is also the result you want to know most.

Gu Chen carried his hands on his back, and walked back and forth for two times. He said, "normally, when a person dies, his heart stops, his blood stops flowing, and his metabolism stops."

"So the liver is destroyed, and the effects of alcohol and anesthetics stop."

"But But this kind of drugs in blood, urine and tissues can remain unchanged, until they are finally destroyed by the corruption process

Looking back at Gao Chuanfeng, Gu Chen added: "but as far as your test results are concerned, if the corpse has passed for just 48 hours, it will not decay very seriously, which means that there has not been any chemical change in the tissue."

"That's the truth." Gao Chuanfeng fully agreed with Gu Chen's opinion, and also said faintly:

"as you just explained, Oxycontin is an anesthetic and analgesic. After ingestion, it can be found in all human tissues, but mainly in the blood and liver."

"However, when a person dies, the drug content will remain unchanged in the body, so these can be detected."

"But it's alcohol, which may be a little tricky, because some corpses produce alcohol in the process of decay."

"Alcohol in the process of corruption?" After hearing what Gao Chuanfeng said, Lu Weiwei immediately became interested and said directly:

"according to the plot you described, due to the lack of corruption, this phenomenon will not appear, right?"

"Even if it does happen, there are solutions." Without waiting for Gao Chuanfeng to open his mouth, Gu Chen chimed in directly: "we can also extract vitreous liquid from Yanqing."

"Does the eye take out vitreous fluid?" After listening to Gu Chen's statement, Lu Weiwei was even more confused.

I've never heard of it myself.

But Gu Chen patiently explained: "vitreous fluid, that is, vitreous fluid, is the colloidal fluid inside the eyeball. The change of alcohol level is often about two hours later than that in the blood."

"It means that at any point in time, the alcohol content of the glass reflects what it was two hours ago."

"So at the beginning of the body's decay, the vitreous fluid will not be affected, and the body will certainly remain the same after being immersed in low-temperature water for 48 hours."

Glancing at Gao Chuanfeng beside him, Gu Chen added: "so forensic medicine will not encounter problems in the examination. It can measure how much Oxycontin and alcohol are contained in the blood when the victim dies."

"Well." Although she knew little about it, Lu Weiwei asked for advice modestly: "so, younger martial brother Gu, what's the use of these values? Can it be concluded that the deceased died of drugs or drowning? And is it murder or accidental drowning? "

Gu Chen thought for a few seconds, but did not answer immediately.

On one side, Gao Chuanfeng is also in deep meditation.

But a moment later, Gu Chen replied ahead of Gao Chuanfeng: "as far as I know, alcohol plus Oxycontin is a very dangerous combination."

"Generally speaking, multiplication can inhibit the respiratory center of the brain and cause ventricular death."

"If these two components exist alone, they are usually not life-threatening. However, as long as they are present in moderate levels at the same time, they may cause death."

Glancing at Zou Qiang's body on the detection platform, Gu Chen also guessed: "this Zou Qiang may have been drunk and unconscious before he fell into the bathtub and drowned."

"But..." After hesitating for a moment, Gu Chen also said cautiously: "but we don't know whether Zou Qiang lives in the villa at ordinary times. We need Xu Fangzhi and the villa owner to know. This needs further investigation."

"But whether it was an accident, suicide or homicide, it doesn't make any difference to me."

"Maybe it's difficult for us to tell the real cause of death of the dead. Maybe we can only judge that the alcohol and stantin contents of the dead are very high, and they died of drowning."

"But if we find bruises in the arms, legs or other parts of the body, there may be other possibilities."

"Including it can be inferred that the dead Zou Qiang had been hit hard, or his action was constrained in some form. In this case, the case may develop in the direction of homicide."

"That's right." After listening to Gu Chen's speech, officer Wang glanced at Gao Chuanfeng beside him and asked, "did you check out other abnormalities in Zou Qiang's body?"

"This..." Takakawa Maple time is not good to make a conclusion, so take the initiative to turn back in the past, continue to say: "let me see."

"Well, all right." Officer Wang nodded silently, holding his chest in both hands, and said: "in principle, if the content of these two drugs is enough to be fatal, it means that Zou Qiang may have died before drowning."

"But then again, if it's not high enough to be toxic, that doesn't count, does it?"

"Yes." Gu Chen agreed with police officer Wang and expressed his own views"The reason is very simple, because homicide, suicide, accidental overdose and drowning look exactly the same at the time of autopsy."

Glancing at Gao Chuanfeng, who is doing a comprehensive examination of Zou Qiang's body, Gu Chen added: "one of the extremely difficult matters that forensic medicine must determine is whether Zou Qiang died of drowning."

"This is often difficult to determine, because the body in the water for 48 hours, you can imagine, the lungs will be full of water."

"But it's just a passive process, because air seeps out and water seeps in."

"Er..." When Gu Chen said this, Lu Weiwei was worried: "if so, what matters will we examine to determine whether the victim Zou Qiang died of drowning rather than drug overdose?"

Gu Chen nodded silently, went to the crowd and continued to express his opinion:

"generally speaking, drowning people struggle to breathe air, and inhale the substances contained in the water, including water, soil, debris, small animals and plant materials."

"If the bathtub in the bathroom of the villa is the first scene, then most of these substances may be eliminated."

"And if it's a passive process, it's not found deep in the lungs."

Go to Gao Chuanfeng in front, Gu Chen said: "moreover, we can look for evidence to confirm that the dead had struggled, hoping to breathe the air."

"When the victim inhales hard and deeply, and when water and debris are sucked into the lungs, coupled with the accompanying cough spasm, his throat and airway tissue are damaged."

"Evidence of trauma and bleeding can also be found in the lining tissues of the nose, throat, airway and lung."

Looking back at Lu Weiwei, Gu Chen also said with a smile: "so you can understand that the discovery of drugs in the victim's body alone can not tell us the actual cause of death and the way of death."

"We also have to look at other things, and the content of the drug in the body of the deceased can help us determine whether the composition of the drug has reached the lethal level, or is only part of the cause of death."

"After all, bruises and other elements of physical trauma may also lead us to investigate homicide."

"Because accidents and suicides are rare, there is no diagnostic basis for drowning because of lung water."

"But as far as all the other matters I discussed before are concerned, they all imply that the death is likely to have been drowned."

"However, it is still impossible to determine whether it was an accident, suicide or homicide."

"Yes." Lu Weiwei nodded silently, also agreed and said: "as you said before, these conditions did not seem different at the time of autopsy."

"The course of such incidents often depends on further investigation."

"So..."

Glancing at the busy maple in Gaochuan, Lu Weiwei said: "so, maple in Gaochuan, what have you checked out?"

"There's no particular wound." Gao Chuanfeng turned off the light of the operation, and also relaxed his airway:

"it seems that I can only start from the doses contained in his body to see if it is because of these doses that he died in the bathtub."

"That's the only way." Gu Chen nodded silently, feeling that at present, the detection can only stop here.

However, if the drug dose in the internal body exceeds the standard, it can be proved that it is the cause of the death of Zou Qiang, and Gu Chen may be able to determine the motive of death.

But at present, the most important thing is to find out why Zou Qiang appeared in the blue mountain villa.

Moreover, during the period of Zou Qiang's disappearance, how many people did he contact? All these need further investigation.

As it was getting late, Gu Chen was on duty again.

A lot of things need he Junchao's help tomorrow.

So after saying goodbye to Gao Chuanfeng, Gu Chen takes officer Wang and Lu Weiwei back to Furong Branch.

……

……

The next morning.

The weather is as gloomy as Gu Chen's mood.

Due to the night shift last night, Lu Weiwei and officer Wang were sleepy.

After that, police officer Ding, Wu Xiaofeng and Ji Zhe, who went to help, were all exhausted.

Therefore, among the three groups of offices, he Junchao is the only one with the best spirit.

When he Junchao just sat down, Gu Chen went directly to him.

"Elder martial brother he, the situation was sent to you in the form of briefing yesterday. I don't know if you read it?"

"I saw it when I got up today. Why? We need to investigate Zou Qiang's whereabouts, right? " He Junchao asked.

"The better he can investigate the situation in detail, the better he is," he said

"We took Zou Qiang's body to the technical department of the Municipal Bureau for testing last night, which also verified that his death time was 48 hours ago."

"It was two nights ago, but where had he been before? We can't know who we've been in contact with and whether we've been drinking or not, so it's up to you. ""No problem." Gu Chen said that, he Junchao immediately knew his value.

Sometimes to be a tool man is also a manifestation of glory.

Patting his chest, he Junchao was also full of confidence and said: "just leave this to me. You were on the night shift yesterday. Go to have a rest first. I'll tell you when I find the clue."

"All right." Gu Chen nodded silently and left.

However, at 10 a.m., Gu Chen kept looking at he Junchao's various operations and was very serious.

But he never called himself.

And Lu Weiwei and Wang police officer, also gave up half a day off, took the initiative to come to the office to work.

Seeing that he Junchao was still busy, Lu Weiwei asked him curiously: "he Junchao, have you done it yet?"

"Strange." He Junchao looked down and said to Gu Chen, "this is not right."

"What's wrong?" Gu Chen asked.

He Junchao shook his head: "reasonably speaking, Zou Qiang's daily life should appear in some monitoring."

"It's strange that the monitoring he passed is intermittent, and it's hard to connect into a complete line."

"A lot of places that can capture him are just at the edge of the monitoring blind area."

"So There was something wrong with his whereabouts during the period before his death, wasn't there? " Gu Chen asked.

"That's about it." He Junchao also nodded and agreed, and said, "and I transferred the surveillance video earlier. From the previous surveillance video, I found that Zou Qiang's law of action is very normal, and I will go wherever I should go."

"But just after he took Xu Fangzhi and you and Lu Weiwei to the murderous house, his whereabouts began to become strange, as if he was deliberately avoiding monitoring."

"True or false?" After listening to he Junchao's words, she and Gu Chen were also involved. Lu Weiwei immediately went to he Junchao and asked:

"according to you, Zou Qiang's whereabouts were normal all the time, but then they began to change after we came out of the murderous house. Doesn't it prove that his whereabouts were abnormal, as if it had something to do with us?"

"That's not what I have to say. That's the truth." He Junchao doesn't want to refute anything. After all, he is seeking truth from facts.

Lu Weiwei was a little confused. She looked weakly at Gu Chen and asked, "younger martial brother Gu, do you think there was anything unusual about Zou Qiang that day?"

"There are, too." Gu Chen stupidly looked at the computer, also said thoughtfully.

Lu Weiwei smell speech, quickly fold back seat, face Gu Chen inquiry asked: "what did you find at that time?"

"Uncompleted buildings." Gu Chen said.

"Uncompleted buildings?" Lu Weiwei a little did not understand, and asked: "what does this have to do with uncompleted residential buildings?"

Gu Chen turned to Lu Weiwei and said seriously: "don't you find that Zou Qiang's attitude when he first met us is different from that when he comes back to communicate with us?"

"Different places? I have to think about that. " Feeling Gu Chen's words, Lu Weiwei scratched her back and began to think hard.

A moment later, Lu Weiwei said, "he was cold to us before Zou Qiang, but later in the discussion of your younger martial brother Gu, he began to look at you with new eyes. Is that right?"

"That's the point, but it's not the point." Lu Weiwei didn't find what she wanted to say, and Gu Chen didn't make a detour and said directly:

"in fact, when I talked with him about the uncompleted residential building, Zou Qiang's mood was relatively stable, but when I talked with him about the uncompleted residential building, if the price didn't rise, there was no possibility of turnover, Zou Qiang's mood suddenly became excited."

"I noticed the obvious change of that attitude at that time. I felt that Zou Qiang should be hiding something in his heart."

After a pause, Gu Chen said: "from then on, I feel that he seems to have some connection with the owner of the uncompleted building opposite the blue mountain villa."

"After all, that piece of uncompleted real estate is the mess of the boss of blue mountain villa, but Zou Qiang is too nervous."

"Especially when I mentioned that those uncompleted buildings have no chance any more..."

"Yes, he has a clear change of attitude." Just as Gu Chen said this, Lu Weiwei nodded and agreed:

"at that time, I also paid attention to it, but I didn't care much about it. Now, if it was our words at that time, he would feel complicated."

"After that, his whereabouts became very mysterious. Maybe it was related to that conversation. Maybe that's the key."

"So..." Officer

Wang looked at the two men, and said, "make complaints about..."

"Zou Qiang has a great relationship with the landlord of blue mountain villa." Gu Chen and Lu Weiwei share the same voice.

They both want to go together.

Officer Wang asked his cheek to think, a little confused: "this is really interesting. The landlord of blue mountain villa, that is, the owner of the shareholders of the uncompleted real estate, can't make a comeback, can't solve the problem of the uncompleted real estate. What's the relationship between him and Zou Qiang?""Under normal circumstances, isn't he a housing agent? Should there be a cooperative relationship between the two? Otherwise, I won't open the door for Xu Fangzhi. "

"That's the problem." Up to now, Lu Weiwei seems to have seen the clue.

Standing up and looking around, Lu Weiwei said calmly: "so in my opinion, this Zou Qiang is not simple. Maybe this uncompleted building also has his interests."

"Maybe, I'm assuming that maybe he has the possibility to buy real estate in uncompleted buildings, and then hand in the funds, but the uncompleted buildings can't be delivered."

"Maybe the owner of the real estate would cheat him and finish the house closing soon, but that day Gu Chen said that, maybe Zou Qiang felt hopeless, so he began to collapse?"

"It's possible." Lu Weiwei expresses her thoughts one by one, and Gu Chen also nods her head.

After all, this is my most intuitive view.

Police officer Wang was puzzled and said, "but the uncompleted building can't be resumed. He also helped the owner of the building act as an intermediary and helped him take the anchor of the murderous house to live in the villa."

"In principle, if the owner of the uncompleted property can't fulfill his promise to resume the uncompleted property, Zou Qiang can ask him for money once the blue mountain villa is sold. It's not contradictory."

"Maybe that's the problem." Gu Chen looked up at the ceiling and said thoughtfully, "so now I really want to know, what's the origin of the landlord? Does he have many interests with Zou Qiang? "

With doubt, Gu Chen turns his eyes on he Junchao.

He Junchao asked weakly: "so, where is the investigation center now

Gu Chen nodded silently: "Zou Qiang disappeared before. The landlord of the villa couldn't get in touch with Zou Qiang, so Xu Fangzhi took the initiative to get the villa key according to the phone."

"So you can start from this point and check the recent status of the landlord of the villa."

In Gu Chen's view, those who can make the real estate uncompleted are ruthless, at least the villa landlord is no exception.
