Detective Training Manual

"Famous Detective Training Manual (!

In this way, Zhou Yan fell into contemplation.

This sense of violation made him feel for a while that this Shen Keke deliberately put the loophole in front of him?

So he opened the detective's notes again...In this case, he can only ask for help from the group of guys in the book, after all, his brain is a bit awkward.

[Yeqi’s cat: Shen Keke’s boyfriend is a smuggler, and the one who repaired the air conditioner died. Can the police confuse this?]

"Ah, this brother obviously didn't understand it. Shen Keke's boyfriend has always been a smuggler. He just wore air-conditioning clothes to hide his identity yesterday. After his death, the police saw him wearing it. Repairing work clothes for the air conditioner mistakenly thought that he was a technician repairing the air conditioner, but after the identity investigation, these little tricks have been seen through."

[Drunk Dream Dongcheng: Don't want the harem! ! ! ! 】

"??? Something weird got in."

[I love her because her name is Hu Ai: She is so smart, why have to wait until now to kill people]

Zhou Yan nodded affirmatively: "Yeah, Shen Keke is so smart, why have to endure so many years to kill Li Dabo? It feels like she is waiting for Zhou Yan. Waiting for an opportunity, she will be able to smoothly control Zhou. Yan invites you to come in front of you, and then kills a person in front of him."

[The man in the false book: Yes, why? Could someone give advice to Shen Coco? 】

"Ah? Make suggestions?" Zhou Yan frowned, "I won't wait until this case is over, and I will find some crow card in Shen Keke's house. Uh, that kind of card seems to have not appeared for a long time. what.",

[An Xia Jiusheng: She left these on purpose]

"Leave it deliberately...but why does she leave these things deliberately?"

[Siyou Leng Tetsuya: I wonder if the place where the incident happened is not this lounge. These clues are left to make others think that the incident happened in this lounge. 】

"This...Is it impossible? The news channel recording has always been on this floor, and there is only one lounge on this floor, so everything must happen in the same room. ."

Just thinking about it, suddenly, Zhou Yan saw a message...

[Chu Chen Ranxue is shocked to leave Dian: Suddenly died? ! It is possible that the vibration frequency is equal to the heartbeat frequency? 】

"Huh?" Zhou Yan was stunned for two seconds: "This kind of thinking is really peculiar. This brother wants to make the vibration frequency correspond to the diastolic heartbeat, which will cause the deceased's heartbeat to beat several times in a row. Can't blood be ejected from the ventricle?

emmm, if that is the case, it may indeed cause sudden death, but it is theoretically feasible, is it a bit too difficult to operate? What a sophisticated instrument is needed to detect the diastolic strength, and the same force must be used , At the right time, just to press back the heartbeat, with this skill, it is really better to hire a killer. "

and many more!

Zhou Yanzheng was negating the idea of ​​this brother, and suddenly, he was completely stunned.

Yeah, invalid heartbeat...

Sudden death does not necessarily mean that the heartbeat stops suddenly, which makes the heartbeat invalid. In fact, in a sense, it is not much different from the heartbeat.

Zhou Yan didn't know what happened to the brain circuit at this moment. He suddenly thought of a very strange and simple experiment that many people would even think of when they were young.

This experiment is really ridiculous, so when most people grow up, they don't think about it anymore.

That is... If you inject air into your body, will you die?

Lin Xi was also thinking at the moment, but when she saw Zhou Yan holding the book, she suddenly stunned, and then stood still...

"You...what's wrong?"

Zhou Yan raised his head and looked at Lin Xi: "Uh, boss, what would happen if a pipe of air were introduced into a person's body?"

When Lin Xi heard this question, he hesitated for a while: "This...I don't know too well. You should ask a forensic doctor about this kind of thing. Hey, it's like this kind of thing that has something to do with medicine. Can't you always insert a few sentences?"

"I don't have a good brain today. It's not important. Call the forensic doctor!"

Lin Xi didn't procrastinate, so he took out his mobile phone and called the forensic doctor.

Soon the phone was connected, and after Lin Xi asked the question, the forensic doctor's answer was also very simple.

"It's okay with less, and you will die if you have more..."

Under Lin Xi's questioning, the forensic doctor gave a detailed explanation.

After the air enters the blood vessel, there are two types.

One is intermittent (slow) injection, and the other is continuous (fast) injection.

Among them, the former is relatively safe. If you are lucky, about 10ml will not cause any problems, but if it exceeds 30ml, it may cause air embolism. If it is blocked on important blood vessels, it may cause death, but chances are Not big.

The latter is very dangerous. For example, if you take a needle and plunge it directly into the patient's body quickly and fiercely, the death rate is extremely high.

After an adult continuously injects 20-40 ml of air, 90% of them will form an embolus in the aorta. If it is at the entrance of the coronary artery or pulmonary artery, the person will die on the spot, even if it is blocked in other places, the person will have a high probability. dead.

And when the child is about 10ml, his life is in danger.

Hearing Lin Xi's report, Zhou Yan's expression became heavier and heavier. Finally, he took the phone and asked himself.

"Then if the injection of a large amount of air causes death, will there be any difference in the blood test?"

"No, it is difficult for air to directly dissolve in the blood. The cause of death of air embolism is not a chemical change, but a physical death, that is, it is blocked." The forensic doctor was still talking slowly.

"Then... that person died, and the blood test still couldn't find an abnormality. Isn't this a **** perfect crime?!"

"No, people who die of air embolism usually have pinholes."

"Then if it is a person with a lot of pinholes, such as a drug addict...Yes, I mean the body of [Li Dabo]!"

"That can also be detected, but it is more troublesome, because air embolism will cause a lot of bubbles in the blood vessels. As long as the corpse is opened, it can be detected~www.readwn.com~ Then you should check it quickly!" Zhou Yelled.

The forensic doctor is also unambiguous: "Isn't this the body that was found in the early morning, and the identity was only confirmed in the morning. Now you let me cut the body and look for bubbles in each blood vessel. How can it be so fast!"

"Um... sorry, you have worked hard." Zhou Yan apologized, and then hung up the phone.

Lin Xi looked at Zhou Yan: "So...you suspect that when Shen Keke interviewed the two of us last night, he injected air into the body of the deceased?"

Zhou Yan still had doubts in his heart, but finally nodded...
