Chapter 567: Real and Fake Death (Seeking Votes for New Case!)

Liancheng Detective Team.

"In ancient times, there have always been legends of corpse fraud."

In the training classroom, Chen Yan was in class.

Detectives who appear on the scene never know what kind of unexpected case they will encounter.

Therefore, on-the-spot judgment and emergency response capabilities are very important.

Liancheng Detective Team has always had the tradition of inviting various experts to conduct various trainings for Liancheng Detective Team detectives. Today, Chen Yan personally came to the podium to tell everyone about some common on-site judgment methods for autopsy.

"Actually, these things are not just rumors. Some stories or legends are indeed true."

Wow!

Although most of the attendees were experienced detectives in the field, there were also many freshly graduated college students who had not been out in the field a few times.

But no matter who it was, when Chen Yan confirmed that he had faked the corpse, he couldn't help but make noises in the classroom.

"Captain Chen," Sun Feng is a detective who joined the first detective team the year before last. He admires Chen Yan extremely, but after hearing this, he still doesn't want to believe it. This conflict with the scientific education he received: "Are you talking about fraud? Do corpses really exist?”

Chen Yan also knew this Sun Feng. He was very smart and perceptive. He was Liu Qingshan's key training target and brought him to the scene most of the time.

"Strictly speaking, this phenomenon exists."

Before anyone could ask again, Chen Yan flipped the projection: "Everyone should know that in ancient times, there was a custom of keeping a vigil after death."

"Do you know where this custom comes from?"

"People are dead, why do they have to be left in the yard for three days, in some places even seven days?"

The projection flips, showing images of ancient Western sacrifices: "Actually, there were similar customs in the ancient West."

"In some remote villages, people will open the lid of the coffin containing the deceased and tie a rope around the hand of the deceased."

"The bell is tied to the other end of the rope, and it hangs in the master's bedroom."

"Actually, this is a way for ancient people to deal with corpse fraud."

The projection is transformed again and is a picture of a human body.

"There are two kinds of death, one is real death and the other is fake death."

"The situation of real death is very simple. After a person suffers a fatal injury, his vital organs are damaged, or there is too much blood loss, which will lead to the death of the body."

"However, there are still some injuries, which may very well cause suspended animation."

"Such as asphyxia, electric shock, poison, brain trauma, etc."

"In ancient times, when medical technology was underdeveloped, many elderly people even fell into asphyxiation coma because they did not spit out a mouthful of thick phlegm."

"But the person is not dead at this time, but his breathing is very weak and his pulse beats very slowly, so slow that it cannot be detected by the human eye. This is actually suspended animation."

"Moreover, the duration of this initial state is not fixed. It may be a few minutes, a few hours, or even a day or two."

"And if it is not discovered, it will be mistakenly diagnosed as death."

"But during the transportation of the corpse, due to impact or other reasons, the phlegm in the mouth of the deceased was spit out or swallowed, and the person in the state of suspended animation would be resurrected. This is the so-called fake corpse." Chen Shang found a person. Picture of the top of the coffin. "

When you zoom in on the photo, you can see there are several deep scratches on the coffin lid.

Chen Yan stood in front of the projection, opened his hands, and compared the scratches: "Look, what do these scratches look like?"

"Did you scratch it with your fingernails?"

"good!"

"When burials were popular in the past, many coffin lids actually had scratches like this."

"Why, are all the corpses fake?"

"Of course not. This is because the body decomposes after being put into the coffin, and the first place where decomposition occurs is in the abdomen."

"In the small space in the coffin, after the decomposing corpse forms a giant view, the upper body can almost fill the entire coffin. This time period can be long or short, depending on the surrounding environment."

"In some places, the temperature is low, and the decay time of the corpse is relatively slow, and the time for the formation of the final giant is also relatively slow, maybe one month or two months."

"As everyone knows, some functions of the human body do not completely stop after death, such as nails. Nails will still grow after death."

"After the giant view is formed, if the corpse's nails are long enough, the arms will be squeezed by the giant view on the coffin cover or coffin wall. As the giant view develops, there will be displacement. ." "Leaving this kind of nail scratch!"

"***...So that's what happened."

"This is the first time I know that this thing can be explained scientifically..."

"I am so surprised…"

Chen Yan raised his hand and flipped the projector again: "It's not important to tell you this. Nowadays, medical technology is very advanced, and the possibility of suspended animation basically does not exist. At least it will not happen easily in the hospital. The dragon incident.”

"But sometimes we encounter corpses at the scene, so the first thing to do is to determine whether the deceased is really dead."

"Of course, this is only for corpses without serious trauma or decay."

"Whether a person dies is not just about whether breathing has ended. In some cases of suspended animation, the respiratory rate of the suspended person is so low that you can't feel it at all if you put your fingers under your nose."

"And in this case, the heartbeat of the fake deceased is also very slow, and the pulse is most likely not palpable. It's not that there is none at all, but the power of the heartbeat is weak and it cannot arouse strong fluctuations in the pulse." "I will be simple today. Teach you some ways and methods to identify suspended animation."

Turn over the projection, Chen Luo.

"Actually, the truth is very simple. The most effective way for us to determine suspended animation is to use the presence of blood circulation to determine whether the deceased is really dead or suspended."

"No matter how slow the suspended breathing is and how weak the heartbeat is, the entire body must be supported by oxygen to function."

"The only source of oxygen is the flow of blood. Once the blood stops flowing, a person will definitely be in a state of true death."

"Once a person is truly dead, you will never see blood flowing out after cutting the skin."

"Of course, this method is invasive, and we need to use some non-invasive means to identify it."

"The first and simplest is to check the blood circulation in the retinal vascular network under the eye. This is the only part of the human body where blood circulation can be directly observed with the naked eye."

“It’s also the method we’ve been using the longest on site.”

Everyone listening to the lecture nodded, Chen Yan was right.

When arriving at the scene, the first thing the detective does is determine whether the other party is dead.

Exploring breathing and feeling for fluctuations in the arteries of the neck are the most common methods.

When these two are not found, the fundus of the eye will be peeled off to check the retinal blood flow.

In fact, if you are in the hospital, you can also inject fluorescein intravenously and observe the jaundice of the conjunctiva half an hour later.

You can also place a stethoscope on your chest or throat to listen for faint breathing sounds.

If all else fails, you can use an electrocardiogram to observe whether there is bioelectricity in the heart.

Of course, there is definitely no such thing on site.

"In addition, if there is no response from this, the last emergency method is to find a thin thread, tighten a section of the little finger, and observe whether the color of the fingertip changes."

"If there is, the person is not dead. If not...then there is no need to read."

＊＊＊＊＊＊＊＊＊＊＊＊＊

These days, Chen Yan's life in Liancheng Detective Team was very peaceful.

Except for some necessary meetings, not a single case occurred.

In addition to daily work, what I say most is to participate in some trainings and lectures.

Chen Yan usually shares some details of the case handling process as an invited lecturer.

Now let alone Liancheng Detective Team, Chen Yan is definitely one of the best in terms of rich experience in handling cases in the entire Liao Province Detective Brigade.

In two years, we have dealt with more than 40 cases, all of which were major cases involving human life. We have to investigate about two similar cases every month. With this case handling frequency, not to mention the Liao Province Detective Brigade, it is the whole country. In the system, statements are unique.

So Chen Yan had time to attend these training meetings, and those who signed up almost broke their heads. In the past, some front-line case handlers at the grassroots level scratched their heads when they heard that there was training.

There is no way, what the teacher said is either unrealistic, or it sounds boring and lethargic.

If you have the time, you might as well patrol your own area.

However, Chen Yan’s lectures are different.

On the one hand, Chen Yan has rich experience in handling cases, and everything he talks about actually happened in the cases he has investigated.

Even if some things sound boring, they are still very attractive when combined with practical analysis.

On the other hand, what Chen Yan said is really useful.

Chen Yan has system-rewarded reconnaissance skill specialization and autopsy skill specialization, so his knowledge base in these areas is very complete.

Many of the things explained have never been heard by frontline detectives at the grassroots level.

Not to mention who Chen Yan is, he is the deputy captain of the Liancheng Detective Team.

Recipients of special individual meritorious service.

Forget about giving lectures, come over and have a look, it's not a worthwhile trip.

Therefore, the trainings or lectures that Chen Yan attended were absolutely full.

Zhang Yunhu's office.

I don’t know where Da Hong Pao hid it, but he still only had three yuan and a bag of scented tea.

Although Chen Yan didn't have any special requirements for tea, tea of ​​different grades still tasted different.

Especially the top-quality Dahongpao and bagged scented tea.

I'm really not used to it.

"Old leader, I heard that when others come to your place, at least they are Biluochun, and at worst they are Tieguanyin. Why do you get scented tea every time I come?"

Although, when Chen Yan was a child, he always saw Chen Jianguo drinking scented tea, whether it was special grade or first-grade, this was the only tea at home when Chen Yan was a child.

But at that time, it was because there was no other tea and I couldn’t afford it.

So, now that we can afford good tea, why do we still drink this?

Zhang Yunhu curled his lips: "Give them Biluochun and Tieguanyin, that's a normal reception."

"After all, those people can't afford Dahongpao and give it to me as a gift."

Chen Yan was stunned: "Joshua, is it because I didn't give you Dahongpao that you kept giving me scented tea?" Zhang Yunhu: "Don't be so straightforward. You basically drank the Dahongpao you gave me. , I just drink with you."

Chen Yan: "..."

He shook his head: "You are the captain of the Liancheng Detective Team!"

"Haha, what's wrong with the captain? He can't afford to drink Dahongpao for thousands of yuan a tael."

"That's true..."

Zhang Yunhu: “…”

Buzz!

The two were chatting when Chen Yan's cell phone rang.

Taking it out and looking at the caller ID, Chen Yan frowned: "It's Lao Li."

"Old Li?"

Zhang Yunhu's hand that poured tea for Chen Yan paused slightly.

If Li Hong calls, nothing good will happen.

"Is there another case?"

Chen Yan nodded: "It's possible."

After answering the phone, Li Hong's familiar voice came: "Vice Captain Chen, how are you doing at work recently?"

Chen Yan's face darkened, and he looked at Zhang Yunhu, knowing that the other party had guessed correctly. With Li Hong speaking in this tone, 99% of the time he had a case.

"I'm telling you, Team Leader Li Da, please stop pretending. If you have any arrangements, tell me directly. I can stand it." "Why, I can't call you if there is no case?"

Chen Yan curled his lips and said, "That's alright. I'm busy drinking Team Zhang's three-and-a-half-yuan bag of scented tea, so I won't stop chatting."

"Three dollars and a bag? Scented tea?"

"Isn't Lao Zhang crazy because of his poverty?!"

Zhang Yunhu: “…”

Chen Yan snickered twice: "Brother Li, I'm in Team Zhang's office. Can you go behind his back for saying bad things?"

Li Hong was not polite: "He has the nerve to treat you with three and a half yuan of scented tea, why don't you let him talk?"

Zhang Yunhu's face was as dark as the bottom of a pot: "Old Li, if you are fine, we are going to have a meeting."

"No, no, no, there's something really wrong..."

After a few minutes, Chen Yan hung up the phone.

Picking up the tea cup on the coffee table, he drank a full cup of tea soup in one gulp: "I'm going on a business trip again this time."

"Have you been to Dan City once? I remember Zhang Yaoming was the captain there?"

Chen Yan nodded. He was more familiar with Dan City: "The rush over there is urgent. I will arrange for members of the serious crime team to set off right now."

At 8 o'clock this morning, a murder occurred in Dan City.

Preliminary investigation results indicate that the deceased committed suicide. Generally speaking, this situation does not require the involvement of the crime squad.

However, because the crime scene was a bit strange, Dan City made a report and requested the participation of the crime squad.

If it is still determined to be suicide, then it will be easier to handle. If it is a non-criminal case, other procedures will be fine. I was just afraid that the suicide was faked. In this case, if no clues were found and it was still treated as suicide, it would be a wrong case.

After leaving Zhang Yunhu's office, Chen Yan first called Liu Qingshan, and after gathering people, he dialed Shen Yunyi's number.

Changhai Group, Shen Yunyi is in a meeting.

After looking at the caller ID of the mobile phone at hand, Shen Yunyi paused the meeting.

It's half past eight in the morning, not long after going to work, and Chen Yan should be in the detective team at this time. The two of them usually don't talk on the phone very much when working, and they always talk via WeChat when something happens.

Unless special circumstances occur.

Therefore, Shen Yunyi suspended the meeting and walked to the reception room next to him to answer the phone.

"Honey, I'm going on a business trip to Dan City for two days, and I'll be back in about three or four days."

On a business trip to Dan City...

Shen Yunyi knew as soon as he heard that there should be a case over there.

"Okay, pay attention to safety. I'll feed you when I come back."

Dumplings on the bus and noodles on the bus, no problem!

Two hours later, Chen Yan rushed to Dan City with Liu Qingshan, Zhang Chaoyang, Wang Gang, and Zhao Bing.

Chen Yan had already contacted Zhang Yaoming, captain of the Dan City Detective Team, before setting off.

At the highway exit, Zhang Yaoming's car was already waiting for Chen Yan.

"Team Leader Chen, I'm going to trouble you again this time!"

After getting off the car, Zhang Yaoming saluted and shook hands quickly.

Chen Yan returned the courtesy: "Captain Zhang, you're being polite when you say that. It's all within your scope."

"Team Leader Li Hong called just now and briefly talked about the situation of the case, but he didn't go into too much detail. We'll get in a car later and go directly to the scene. You can give us an overview of the situation on the way."

Zhang Yaoming nodded: "Okay, let's go directly to the scene."

While talking, Zhang Yaoming led Chen Yan into his car: "The case was reported to the police at 8 o'clock this morning."

"After we arrived at the scene, we found that the deceased had been stabbed 32 times, but there was no trace of anyone else at the scene. The detectives who investigated the scene and the autopsy investigators concluded that it was suicide!"

He was stabbed 32 times and committed suicide? !

Are you kidding me?
