Liancheng detective team.

"In ancient times, there have always been legends about fraudulent corpses."

In the training classroom, Chen Yan was in class.

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

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

The Liancheng detective team has always had a tradition of inviting various experts to conduct various trainings for the detectives of the Liancheng detective team. Today, Chen Yan personally went to the podium to talk to everyone about some common on-site judgment methods about corpse inspections.

"Actually, these things are not rumors. There are some stories or legends, which are really true."

Wow!

Although most of the lecturers were detectives with rich experience in the field, there were also many college students who had just graduated and hadn't been to the scene a few times.

But no matter who it was, when Chen Yan was affirming the fraudulent corpse, the classroom still couldn't help the noise.

"Team Chen," Sun Feng is a detective who joined the No. 1 detective team the year before last. He admires Chen Yan extremely, but he still doesn't want to believe it after hearing this. The scientific education he has received conflicts: "Are you talking about fraud? Do corpses really exist?"

Chen Yan also knew this Sun Feng. He was very clever and savvy. Liu Qingshan's key training object would bring him to the scene most of the time.

"Strictly speaking, this phenomenon exists."

Before everyone could ask another question, Chen Yan flipped the projector: "Everyone should know that in ancient times, people generally had the custom of keeping their spirits after death."

"Do you know how this custom came about?"

"Everyone is dead, why put it in the yard for three days, or even seven days in some places?"

The flipping of the projection is the sacrificial image in the ancient West: "Actually, there were similar customs in the ancient West."

"In some remote villages, people will open the lid of the coffin containing the dead, and then tie a rope on the dead's hand."

"There is a bell attached to the other end of the rope, and it hangs in the master's bedroom."

"In fact, this is a way for the ancients to deal with fraudulent corpses."

The projection is transformed again, and it 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 true death is very simple. After a person is fatally injured, the vital organs are damaged, or the blood loss is too much, which will lead to the death of the body."

"However, there are still some injuries, which are likely to cause suspended animation."

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

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

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

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

"And if it is not found, it will be misjudged as death."

"However, during the transfer of the corpse, due to the impact or other reasons, the sputum in the deceased's mouth was spit out or swallowed, and the person in the state of suspended animation would be resurrected. This is the so-called fraudulent corpse." The top cover picture of the secondary coffin. "

Zooming in on the photo, there are several deep scratches on the coffin lid.

Standing in front of the projection, Chen Yan spread his hands and compared the scratches: "Everyone, what does this scratch look like?"

"Nail scratches?"

"good!"

"When burials were popular in the past, many coffin covers actually had such scratches."

"Why, are all the corpses fraudulent?"

"Of course not. This is because the body decays after it is put into the coffin, and the first place where corruption occurs is the abdomen."

"In the narrow space of the coffin, after the decaying corpse forms a giant, 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 to form the final giant view is also relatively slow, maybe a month or two months."

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

"After the giant view is formed, if the nails of the corpse are long enough, they will squeeze their arms against the coffin cover or the coffin wall under the pressure of the giant view. As the giant view develops, displacement will occur. ’” “Thereby leaving such nail scratches!”

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

"This is the first time I know that this thing can be explained clearly by science..."

"I am so surprised…"

Chen Yan raised his hand and flipped the projector again: "It's not the main thing to tell everyone. Now that medical technology is very advanced, the possibility of suspended animation basically doesn't exist. At least in hospitals, it's not easy for such a black hole to appear. Dragon incident."

"But we sometimes encounter corpses at the scene, so the first thing we need to do is to judge whether the deceased is really dead or not."

"Of course, this is only for corpses that have no serious trauma or corruption."

"Whether a person is dead or not is not just whether the breathing is terminated. In some states of suspended animation, the respiratory rate of the suspended animation is very low, and it is impossible to feel it at all with a finger under the nose."

"And in this case, the heartbeat of the fake dead is also very slow, and there is a high probability that the pulse cannot be felt. It's not that there is no pulse at all, but that the strength of the heartbeat is weak, and the pulse cannot be strongly fluctuated." "I simply said today. Teach everyone some ways and methods to distinguish suspended animation."

Flip the projection, Chen Luo.

"Actually speaking, the reason is very simple. The most effective way for us to judge suspended animation is to use the existence of blood circulation to determine whether the deceased is real or fake."

"No matter how slow the breathing and heartbeat of the suspended animation is, the whole body must be supported by oxygen in order to function."

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

"Once a person is really dead, after cutting the skin, there is absolutely no blood flowing out."

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

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

"It's also the method we've used the longest in the field."

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

When they appeared on the scene, the first thing the detectives did was to judge whether the other party was dead or not.

Visit breathing, feel the carotid artery fluctuation is the most common means.

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

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

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

If it doesn't work, you can use an electrocardiogram to observe whether there is bioelectricity in the heart.

Of course, there must be no such thing on the scene.

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

"If there is, the person is not dead, if not...then don't read it."

＊＊＊＊＊＊＊＊＊＊＊＊＊

In the past few days, Chen Yan's life in the Liancheng detective team was very peaceful.

Except for some required meetings, none of the cases took place.

Apart from his daily work, what Chen Yan does most is to attend some trainings and lectures.

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

Not to mention the Liancheng detective team, but even the entire Liao province detective team, Chen Yan was definitely one of the best in terms of rich experience in handling cases.

In two years, more than 40 cases have been handled, and all of them are major cases involving human life. About two similar cases are investigated every month. With this frequency of handling cases, not to mention the investigation team in Liao Province, it is the investigation in the whole country. In the system, statements are unique.

So when Chen Yan had time to attend these training sessions, the people who signed up for it almost broke their heads. In the past, some grassroots frontline case handlers scratched their heads when they heard that there was training.

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

If you have this skill, you might as well go to patrol your own jurisdiction.

However, Chen Yan's lectures are different.

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

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

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

Chen Yan has specialization in survey skills rewarded by the system and specialization in autopsy skills, so his knowledge reserve in these areas is very complete.

Many of the things explained were never heard by grassroots front-line detectives.

Not to mention who Chen Yan was, he was the deputy captain of the Liancheng detective team.

Recipient of personal special meritorious service.

Don't talk about giving lectures, just come and experience it, it's not worth the trip.

Therefore, the training or lectures that Chen Yan participated in were absolutely full.

Zhang Yunhu's office.

Dahongpao didn't know where to hide it, but there was still only three yuan and five bags of scented tea.

Although Chen Yan didn't have any special requirements for tea leaves, there are still differences in the taste of tea of ​​different grades.

Especially the top Dahongpao and scented tea in bags.

I'm really not used to it.

"Old leader, I've heard that when others come to you, at least it's Biluochun, no matter how bad it is, it's Tieguanyin. Why do I always come here for scented tea?"

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

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

So why drink this when you can afford good tea now?

Zhang Yunhu curled his lips: "Giving them Biluochun and Tieguanyin is a normal reception."

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

Chen Yan was stunned: "Co-author, you keep giving me scented tea because I didn't give you a Dahongpao?" Zhang Yunhu: "Don't be so straightforward, you basically drank the Dahongpao you gave me. , I just drink with you."

Chen Yan: "..."

Shaking his head: "You are the captain of the Tangtang Liancheng detective team!"

"Hehe, what's wrong with the captain, he can't afford a Dahongpao that costs thousands of dollars."

"That's true..."

Zhang Yunhu: "..."

Buzz buzz!

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

Taking it out to see the caller ID, Chen Yan frowned: "It's Lao Li."

"Old Li?"

Zhang Yunhu slightly paused the hand that was pouring tea for Chen Yan.

If Li Hong called, there must be nothing good.

"Is there another case?"

Chen Yan nodded: "There is a possibility."

After answering the phone, Li Hong's familiar voice came: "Vice Captain Chen, how is your work?"

Chen Yan's face darkened, and he looked at Zhang Yunhu, knowing that the other party's guess was right. If Li Hong spoke in such a tone, 90% of the time there was a case.

"Let me tell you, Team Leader Li, don't hold back. If you have any arrangements, tell me directly. I can stand it." "Why, can't I call you without a case?"

Chen Yan curled his lips: "That's fine, I'm busy drinking Team Zhang's three yuan and five bags of scented tea, so I don't want to chatter."

"Three yuan and five bags? Scented tea?"

"Isn't Lao Zhang insanely poor?!"

Zhang Yunhu: "..."

Chen Yan snickered twice: "Brother Li, I'm in Team Zhang's office, can you speak ill of him behind his back?"

Li Hong was not polite: "He has the nerve to entertain you with scented tea at 3.5 yuan, why don't you let me tell you?"

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

"Don't, don't, there's something wrong..."

A few minutes later, Chen Yan hung up the phone.

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

"Danshi, have you been there once? I remember Zhang Yaoming was the captain there?"

Chen Yan nodded, he was more familiar with Dan City: "The urging over there is urgent, I will arrange for the members of the serious crime team to go."

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

Preliminary investigation results show that the deceased committed suicide. Generally speaking, this kind of situation does not require the participation of the serious crime team.

However, because the scene of the crime was a bit strange, a report was made from Dan City, asking the serious crime team to participate.

If it is still determined to be a suicide, then it will be easy to handle. For non-criminal cases, just go through other procedures. I am afraid that the suicide is faked. In this case, if there is no clue and it is treated as a suicide, it will be a wrong case.

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

In Changhai Group, Shen Yunyi is in a meeting.

Looking at the caller ID of the mobile phone at hand, Shen Yunyi suspended the meeting.

It's 8:30 in the morning, and it's not long since he just went to work. At this time, Chen Yan should be in the detective team. The two of them usually don't call on the phone when they are working, and they talk about it on WeChat when they have something to do.

Unless special circumstances occur.

That's why Shen Yunyi suspended the meeting and went 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."

Dan city business trip…

As soon as Shen Yunyi heard it, she knew that there should be a case over there.

"Okay, be careful, I'll come back and feed you."

Get on the dumpling and get off the noodles, no problem!

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

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

At the highway exit, UU Reading www.uukanshu.com Zhang Yaoming's car was already waiting for Chen Yan.

"Group 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 are being polite when you say that, it's all part of your job."

"Leader Li Hong called just now and talked about the situation of the case, but not in detail. We will take a car later, let's go directly to the scene, and you can introduce the general situation on the way."

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

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

"After we showed up 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 inspected the scene and the autopsy detectives made a judgment that it was suicide!"

32 knives in the body, suicide? !

Are you kidding me?
