Return to 1983 and be a detective

After all, Xu Shan has watched more than 1000 episodes of Conan and read countless mystery novels.

He had also read specialized forensic medicine textbooks, so he answered without hesitation: "Yes, look at the corpse. It has a giant look. The so-called giant look means that the corpse has swollen. This is because the microorganisms in the body are no longer human. It is caused by the restriction of the immune system and the decomposition of the human body. The production of giants requires different times at different temperatures and seasons. For example, it may take more than a week in spring, and two to three days in summer. .”

Liang Feng was impatient, so he couldn't help but say after hearing this: "Then the direction of our investigation is to investigate the people who disappeared two to three days ago? I will let the bureau arrange to investigate."

"The current population of Longshui County must be more than 20. If we investigate like this, it will be like finding a needle in a haystack. In fact, the scope of our investigation can be narrowed. First of all, this female corpse obviously floated down the river, so Longshui There is no need to investigate the Beixiang side of Shuixian County. We only need to investigate the missing people along both sides of the river. Secondly, the girl's dress is not a rural girl. It can be reduced to a town, factory or mine, and finally it will be based on the collision caused by the deceased's body. Judging from the scars on her body, she did not pass through any shoals while drifting, so the trace back to the source is only within a range of five kilometers at most."

Liang Feng was dumbfounded and couldn't help but widen his eyes: "Can this be found out from the corpse? It's really amazing."

Xu Shan smiled slightly: "Where is this? In fact, this girl's fatal injury was a heavy blow to the head, and the thing that hit the head was a hollow stick. The most convenient material we can use here is Longshui Steel. I guess she is an employee of Longshui Steel Factory..."

Su Jing couldn't listen anymore: "Xu Shan, you are so nagging, why don't you tell fortunes? Are you still an employee of the steel factory? What if you are not?"

Xu Shan was naturally confident, because the fatal wound on the deceased's head had the words "Longgang Special" on it. This was a special steel pipe manufactured by Longshui Steel Factory. It is said that it is not sold to Longshui County, and it is impossible for ordinary people to Can be used as a weapon.

His old man smiled on the ground: "Officer Su, let's make a bet. If the deceased is not an employee of the steel factory, I will kowtow to you and admit my mistake."

"Hmph, then just wait and lose."

"But what if the deceased was an employee of the steel factory? Officer Su, what do you have to lose to me?"

Su Jing spat and turned her face: "Bah, you rotten gambler, who would bet with you?"

At this time, Cheng Zhangsheng asked tremblingly: "Leader, didn't you say that someone moved the body to my melon shed? Someone wants to harm me and accuse me, you can't ignore it."

"Uncle Cheng, don't worry, I was just about to talk about your matter. Indeed, it is important to find the murderer, but we must first find out the guy who moved the body. By finding him, we can also rule out a few things. A possibility. Uncle Cheng, think about it, have you ever made enemies with anyone?"

Cheng Zhangsheng scratched his head: "No, I never seem to quarrel with others. After all, I cultivated my melon field by myself. I am afraid that others will report me. If someone comes to cut off my tail, my melon field Isn’t it in vain?”

What Cheng Zhangsheng said was very reasonable. He kept his tail between his legs and did everything for his five acres of melon land.So he couldn't remember who had such a deep hatred against him.

On the other hand, Cheng Zhangsheng has always been kind to others.

Therefore, a person who has a Buddha in his heart sees everyone as a Buddha. He is a good old man, and everyone thinks he is a good person.

Since Cheng Zhangsheng couldn't remember it, Xu Shan had to look at the traces of dragging the body again. This time he looked at the footprints.

The sand is soft and dragging heavy objects will naturally leave footprints.

Everyone has their own walking habits, different physical conditions, and different footprints. Even twin brothers will leave different footprints. Therefore, there is a special skill for distinguishing footprints called coding.

In his previous life, Xu Shan had seen code tracking masters from many reports. For example, there was a code tracking master in Inner Mongolia named Ma, and there was a code tracking family in Shandong named Yu. They summarized their coding tracking experience, An internal teaching material for trace studies was formed.In his previous life, because Xu Shan was interested in reasoning, he spent a lot of effort to get one. During the three years on the farm, he practiced all the time, and now he has basically gotten a glimpse of the ropes. .

After looking at the footprints, he came back and asked Cheng Zhangsheng: "Uncle Cheng, have you had any trouble with a fisherman recently? This fisherman's back is a bit curved, and his left foot is a little shorter than his right. He is probably in his fifties... …”

Su Jing said on the side: "You pretender, you are completely making this up."

Xu Shan ignored her and stared at Cheng Zhangsheng.

Cheng Zhangsheng also struggled to recall.

Liang Feng was also a little surprised. Although he was willing to believe Xu Shan, Xu Shan could see the skills of a real person just by looking at the footprints. It was amazing: "How did you tell? You can tell whether a person is a fisherman from the footprints. This thing is too mysterious."

Xu Shan Xu Xiao explained: "Captain Liang, it is actually very simple to come to this conclusion. The soil in the melon field is soft, and the footprints left here are very clear. It can be seen that this person's footprints are of the same depth from front to back. Generally speaking, dragging When the corpse was found, if the person pushed backwards, the marks at the soles of the feet would be deeper, but now the depth is the same before and after, which can only mean that the person's back is a bit curved. And the footprints are left by bare feet. Generally speaking, People who are used to walking on land without shoes all year round have thick skin and calluses on their feet, and the footprints they create are inconsistent with the footprints at the scene, so there is another possibility: people who have been in the water or on boats all year round. Long Shui The county is named after the water. There are many fishermen above the dragon water. The site is close to the river, which makes it easy for fishermen to come. It is likely that the floating corpses were fished out from the river. I was so frightened that I didn’t know what to do with it. Just dragged it here to the melon field."

At this time, Cheng Zhangsheng reported a name: "The person you are talking about should be Lao Chuantou, but I don't seem to have offended him. It seems that it was the last time he asked me for a melon to eat, and I said the melon in the field was not ripe yet. , it will definitely be a waste to eat now..."

Liang Feng was stunned after hearing this. He thought Xu Shan had guessed it, but his theory turned out to be convincing. Now Cheng Zhangsheng actually said a name, which made him overjoyed: "There really is such a person. His family Wherever he lives, let’s go over and meet him and see what flaws he has.”

Under the leadership of Lao Chengtou, they found Lao Chuantou.

Lao Chuantou was mending a net in the yard. When he saw Cheng Zhangsheng and the police coming to the door, he was so frightened that he dropped the net and ran away.

As soon as he turned his head, Liang Feng rushed out with a whip and slapped his back with one hand, knocking the old boat down.

Old Chuantou had never seen this formation before, and he quickly shouted: "I didn't kill anyone."

After hearing this, Xu Shan was secretly amused. This was just self-inflicted.

Although Liang Feng didn't know how to solve the case, his intuition was quite sharp: "So you really moved the body to Uncle Cheng's melon shed?"

"I'll do it, I'll do it all... It's really not my fault. I just wanted to scare him, but I really didn't kill anyone. The corpse hit my fishing net by itself, and it even broke my net." It scared me so much. At that time, I happened to be collecting the net next to his melon field. Thinking that Old Cheng would not give me melons to eat, I became so angry that I dragged the body with me. I threw it into the melon shed. How can I, a fisherman, have any evil intentions..."

The old captain didn't realize what a big mistake he had made, and he was still talking plausibly.

Xu Shan also sighed secretly in his heart. There are so many people who are legally illiterate these days. Everyone lives by simple values, but they can still live in peace on the surface. It is estimated that this situation can only occur in a civilization like our country. Bar.

Liang Feng was so angry that he slapped him in the face, took out the handcuffs from his waist, and cuffed him behind his back: "People like you should be locked up and sent to a farm for a few years to be rehabilitated. They grew the crops with their own labor." Watermelon, I give it to you as a favor, but not giving it to you is my duty. Just because you didn’t give me the melon to eat, you moved the body to scare people, which is really lacking in virtue. Follow me back to the station now, and I will personally interrogate you.”
