Police order

Chapter 285 How to Kill

On November 11, all the students sat in the classroom, waiting for the arrival of the new teacher.

Qiao Qi left, and the new teacher will arrive soon. The emotions of the students are quite complicated.There is reluctance, relaxation, and anticipation.

The person who opened the door and entered the room was an unremarkable old man who looked over 60 years old, wearing reading glasses, wearing a bulging down jacket, and holding a thermos cup in his hand.

After entering the door, the old man slowly put the water glass on the table, and then took off his thick down jacket without haste.

The temperature outside is about seven or eight degrees, and the heating starts today, and the students basically wear long-sleeved clothes indoors.
The old man lowered his head thirty degrees, looked up at everyone through the upper edge of the flower mirror, then raised his head, stepped onto the podium, and wrote his name on the blackboard—Miao Jingxuan.

After the old man wrote down his name, many students below searched for this person, some asked in the group, and many people came from Aite Yanyu.

"One of the professors at the Police University, a student of Wu Lao and Gao Lao." Yan Yu briefly introduced.

"Which old Wu and old Gao?" Those who didn't understand continued to ask.

"Wu Guoqing, Gao Guangdou." A knowledgeable person introduced them.

Speaking of this, I have to talk about the "Eight Tigers of Criminal Investigation".This is the first batch of specially-appointed experts in the ministry. Except for the deceased Zhang Xin (a first-class hero model), everyone else is in their 80s.

Wu Lao is a senior engineer of criminal science and technology, and Gao Lao is also a senior engineer and an expert in explosion analysis.

Everyone knows what level this Professor Miao is under the tutelage of these two.

After a brief chat with 90 people in the WeChat group of "Love each other as a family", everyone sat down and was ready to attend the lecture.

The leader of this group is Liu Liwen.

After Liu Liwen formed this group, everyone unanimously decided that even if most people withdraw from the selection of professional police officers, the group will not disband, and they can still chat with each other on a daily basis.

Miao Jingxuan looked at everyone, with a smile on his face: "I think everyone is a little nervous, let me introduce myself first, my name is Miao Jingxuan. In the next month, I will tell you about the investigation skills of criminal cases. "

Miao Jingxuan's smile made everyone relax a lot.

"The first lesson I'm going to teach today is how to kill people." Just as everyone relaxed, Miao Jingxuan raised the atmosphere again with a word, "In researching murder cases, you must first learn the methods of killing people. If you don't master these methods, How to deduce the composition of the case?"

If this sentence is heard from other places, it would be quite scary, but in Miao Jingxuan's view, this is the normal way of learning.

Then, Miao Jingxuan took out five small items from his small bag.

The first one is a small screwdriver, the metal part is only about 5cm.

The second one is a nail clipper, and it is very kawaii.

The third is the button battery removed from the car key.

The fourth was a small plastic medicine bottle, and no one knew what was inside.

The fifth is a thin book with only dozens of pages, more like a brochure.

The sixth is that Miao Jingxuan put his water glass on the far right, and he doesn't know if it counts as an object.

"How these things can effectively kill people, anyone who has an idea can stand up and answer." Professor Miao picked up his cup, took a sip of tea, and then put it back.

At this time, someone stood up immediately: "A screwdriver can stab people to death. If it hits the vital point, this length is enough. And that medicine bottle, if it contains poison"

While this man was talking, Miao Jingxuan unscrewed the small medicine bottle and showed everyone that it was empty. This is an ordinary small medicine bottle.

"I'm afraid this is not possible." The one who stood up looked at the things on the table, "Mr. Miao, can your cup kill someone?"

"It's possible." Miao Jingxuan nodded.

After this person sat down, Yan Yu stood up: "The nail clippers are cut off in the middle, and there are blades. If they are inserted directly into the carotid artery, they can kill people; button batteries are strictly forbidden to be swallowed. If people swallow them and do not seek medical attention in time, they may burn. Piercing the mucous membrane of the stomach leads to death; small medicine bottles can block the trachea and suffocate people; books can be torn open, and a single page of paper is also very sharp. of muscle tissue."

After Yan Yu finished speaking, everyone looked at her, thinking that she is cruel enough.
Professor Miao didn't expect these students to have such rich imaginations, so he nodded with satisfaction: "This student is right. The solutions she mentioned just now are all cases we have seen in actual cases."

When Miao Jingxuan said this, the audience was in an uproar. Is human life so fragile?Among other things, can nail clippers and button batteries really kill people?

If you hold a poison in your hand that is enough to kill you, then you are somewhat nervous.But no one is nervous about holding a button battery.

"Teacher, can you tell me the specific cause of death after eating the button battery?" Someone asked directly.

"Button batteries are highly corrosive and alkaline, and they can damage the human body in several ways. The first is short-circuiting in the humid, conductive environment in the stomach, releasing a lot of heat, scalding mucous membranes and tissues; the second is the surface The zinc oxide in the battery can react with the protein of the human body; the third is that the leakage of battery fluid can corrode the mucous membrane. The cause of death is usually esophageal ulcer, perforation, fistula between esophagus and thoracic aorta, resulting in massive hemorrhage, and finally died of hemorrhagic shock.” Miao Jingxuan meticulously said explained.

With that said, Miao Jingxuan turned on the big screen next to the blackboard and began to formally attend the class. The content of the first class today is how to kill.
"The easiest way to kill people is to find them on the battlefield. Most of the weapons developed by humans are to kill opponents more effectively, whether it is guns, artillery or nuclear weapons, and of course biological and chemical weapons. This is the beginning of the birth of weapons. Purpose. In our handling of cases, military means are basically invisible, but many means have similar principles. The death of the human body seems to have many reasons, but in fact the same goal is achieved by different routes. can cause death"

Miao Jingxuan's opening is the standard 404 content.

Where can I listen to this kind of class?
While listening to this class, Lu Ling still had a lot of thoughts.He is like this, with a strong brain ability, and always likes to think about things.Lu Ling felt that if Professor Miao went to the prison to give this course, the inmates would probably be desperately taking notes.

The content of today's class is actually very simple. It is to understand the suspect's methods in a targeted manner by learning "how to kill".

Lu Ling understood this teaching mode very well. To put it simply, it was a change of thinking, allowing the police to think from the perspective of a suspect.
