Return to 1983 and be a detective

When Xu Shan read the entire dossier, he couldn't help but feel excited.

There is only one feeling echoing in my heart, that is, I have watched this episode.

Yes, this case was indeed seen by Xu Shan in later generations. Because it was very strange and classic, it was talked about as a case in later generations. The person who talked about this case was Mr. Ma Lao, the leading criminal psychology expert in China, and Xu Shan also I almost finished listening to Mr. Ma's class without stopping.

The case is also very simple. A family of three slept on the same bed. The husband slept in the bed, the children slept in the middle, and the wife slept beside the bed. At around two o'clock in the morning, the wife was suddenly woken up by her husband and saw her husband sitting upright. Then he called out his wife's name: Aihua.Then he fell straight down.

After turning on the light, I found that the bed was covered in blood. Her husband's throat had been cut and he died.

The strange thing about this case is that three people slept in the same bed. How did the murderer bypass his wife and children and kill the husband who was sleeping on the innermost side of the bed.

Moreover, the deceased's throat was cut to death, but how did the wife hear her husband call her name?

You must know that if a person's neck is cut, the airflow will escape from the break, and the person will simply be unable to speak. How could the deceased call his wife's name?

So after the incident, the wife became the biggest suspect. The direction of solving the case was to solve the problem of the couple having a bad relationship, the wife having an affair, or the husband having an affair. It has been almost half a month since the incident. Come on, I still don’t have any clue.

And Xu Shan, who comes from a later generation, can be said to have a good understanding of this case, at least he knows who the murderer is.

But now he couldn't say it directly.

Instead, I took out my work manual, took out the pen from my pocket, wrote and drew on the paper, and made a mind map.This is a habit that Xu Shan developed when he was studying in later generations.

Mind mapping, after being invented by a corrupt Chinese in the 70s, has been widely disseminated, widely accepted by people from all over the world, and widely used. It can be regarded as a very useful tool for taking notes. This thing is outlined and clear at a glance. Also easy to remember.

When Xu Shan draws mind maps, he actually does it for a show, so his words should be as beautiful as possible, and his movements should be a bit performative.The big guys looked at Xu Shan's performance there with doubts in their eyes.

After Xu Shan finished drawing the mind map, Mr. Cao asked: "Comrade Xiao Xu, what do you think about this case? You might as well say it to clear the ears of us dizzy old guys."

Xu Shan quickly said that he didn't take it seriously, but he took his work manual and slowly analyzed: "First of all, I don't think this matter should be solved from the direction of love murder, because no matter how bad the relationship between the couple is, if there is a child sleeping, You can't kill someone in front of your child while you're in it. It's unreasonable. In addition, I saw the part where the child was interrogated. In the eyes of the child, his parents have always been very loving, and they never had any quarrels or quarrels. My husband is still fine. Call your wife by her nickname, Aihua. This cannot be false."

"And the husband called his wife's name before he died. This was even more of an expression of their love. Those were the two words he wanted to say most when he was dying. If this is not love, then what is love? What? So I don’t think it was a love killing.”

"If someone kills someone for money, I don't think it's reasonable, because none of the valuables in the house are missing, and there are no signs of the house being rummaged through. The whole family is sleeping soundly. If someone goes there for money, they go in and out quietly. It’s in line with normal people’s logic.”

"So it can be deduced that it can only be a vendetta. I guess the bed of the deceased should be by the window. Generally speaking, Feng Shui pays attention to the southeast bed and northwest stove. The layout of the building's room, the double bed will always be arranged Next to the window. The time of the crime was when the autumn tiger was raging. The weather was hot and everyone had the habit of sleeping with the window open. So I guess the murderer stuck a knife through the window and slashed his throat. He killed the person and then absconded. leave."

Xiao Zhang snorted unconvinced: "Your inference is just the thinking of ordinary people. Then tell me, why can the deceased call his wife by her nickname despite having his trachea cut off? So the deceased's wife He must be lying."

Xu Shan glanced at Xiao Zhang and saw the young man's dissatisfaction with him.

Young people are all very energetic. If they are not energetic, can they still be called young people?

Therefore, every young man feels that he is unique and that I am the best in the world, until he is beaten black and blue by society, and is finally forced to reconcile with the world and accept the fact that he is just an ordinary person with nothing to do and nothing special.

This Xiao Zhang should be Mr. Cao’s apprentice or something like that. Well, his name is Zhang Xing?It seems that he compiled this file, and the writing is really good...

Wait a moment, Xu Shan silently recited Zhang Xing's name twice in his heart, and his eyes suddenly widened.

Damn it, is this Zhang Xing the youngest of the Eight Tigers of Criminal Investigation?That big shot was good at handwriting analysis and creating shadow graphics. He could draw the appearance of a suspect based on the words of the victim and witnesses. The public security department was able to arrest people based on the drawn appearance of the suspect. Get the right one.

All in all, this magic pen Zhang Xing seems to be just a young boy now.

Unexpectedly, this would be the future boss. Xu Shan was overjoyed and wished he could worship this future boss now.

But now he had to calm down, and put on a very calm look with a frown and a cold expression: "Comrade Xiao Zhang, you must have never killed a chicken... or a duck."

"No, so what?"

"I'm applying to go to the farmer's market right now and buy five chickens or five ducks. We need to prove this in practice, that is, if the trachea is cut, whether the scream can be made."

When the big guys heard this, they all became interested. This was the first time they had seen this kind of verification method.

Mr. Cao looked at Xu Shan with interest: "Could it be that you want to imitate Zhang Ju in roasting pigs and use this method of verification to restore the facts of the case?"

"Actually, I already have a firm answer in my heart. Moreover, the fact that the deceased called his wife is only a detail that affects our judgment and does not affect our process of solving the case. I also do this so that Comrade Xiao Zhang and all the big guys can understand , I am very practical.”

In fact, these criminal investigation experts often conduct experiments themselves. For example, there is a trace inspection expert who discovered that everyone’s fingernail marks are different. For this reason, he conducted countless experiments and collected an unknown amount of data. It was finally proven that everyone’s nail texture is different, and like a person’s fingerprints, it can also be used as evidence.In the future, it will really happen that half a piece of fingernail can be used to solve a crime.

In those days when DNA technology had not yet developed, the big guys relied on constant experiments to improve every process of criminal investigation, ensuring the detection rate and peace of mind in an era when technology was underdeveloped.

And Xu Shan is actually just a little stick standing on the shoulders of giants.

So as soon as Xu Shan proposed to kill the chickens for verification, someone immediately went to do it. After a while, they actually got five chickens from the farmer's market and delivered these five chickens to Xu Shan.

Xu Shan actually did not dare to kill the chickens. He stared at the chickens with wide eyes and refused to touch them. There was a criminal investigation boss on the side who saw Xu Shan's predicament at a glance and asked with a smile: "Yes." Have you ever killed a chicken?"

Xu Shan scratched his head in embarrassment and said, "Yes, my family was poor at that time. We raised chickens for the bank, but we couldn't bear to kill them."

"I can kill for you, but you have to give me something in return." The boss looked at Xu Shan with a smile.

"Ah? How can I be so virtuous? How can I repay you, old man?" Xu Shan looked at the old comrade named Duan Zeshan, but he thought to himself that he didn't seem to have any contact with him. This guy wants to let him go. What are you doing?

"No, you do. You can help me now. To tell you the truth, my niece is Li Yanzi. She reported the situation to me and said that you are a great talent and you even guided her to solve a murder case, so I There is no request from anyone else. If you manage her more strictly for me and give her more work, I will be satisfied..."
