Chapter 130 Speaking for the Wounded
The victim's husband also saw that Wu Jun and Jiang Yuan seemed to be in disbelief, and explained in a low voice: "I just blocked it, and the injury was not serious. The man turned around and ran away."

If you block it once, you will get splash damage, and if you block it a few times, you will have a few hits, unless you are not injured.

Wu Jun and Jiang Yuan laughed even more weirdly.

This shows that the person in front of him doesn't know anything about bloodstains.

As we all know, splash injury is very easy to see. If you want to simulate it, you can take a cup of blood... If not, you can use urine instead. Fill a large cup and pour it on the white wall. Blood, or yellow urine, is what a spatter looks like.

Of course, if you just want to take a look at it for a short time, water can also be used instead.

And the man in front of him was obviously talking nonsense with his eyes open.Although there was blood in the place he was pointing at, it didn't look like a blood spatter at all, and it wasn't immediately exposed.

Don't even know about bloodstains, how dare you kill someone?

The development of the modern criminal investigation field has long raised the threshold of violent crimes.

If you run away after hacking, it may take a while for the police to lock down the suspect.Returning to the crime scene, still as an eyewitness, as a result, he didn't even have the basis of bloodstain science, so how could he make it up.

Wu Jun raised his chin and gestured to the two criminal police behind him.

The detective who appeared on the scene was smarter than a dog. He wrinkled his nose, and noticed the position of his companions from the corner of his eyes. Then he took two steps forward at the same time, and immediately grabbed the man's arm.

"Don't move." The old policeman was talking, and the younger Kaka put the handcuffs on.

The cold handcuffs were slightly heavy, as if they were being forced to hold the handles.

The face of the victim's husband turned a reddish brown.

"I'm really... I just blocked the knife. What are you arresting me for?" The victim's husband struggled uneasily, wanting to call someone, but didn't dare to call someone.

The villages in Beiningtai are very particular about unity. Including Jiangcun, it is always the case that if you shout in the village, someone will jump out to help.

But the man hesitated, and still defended himself: "If you don't believe me, you can find the portrait master, and I will tell you what that person looks like."

Wu Jun naturally wouldn't follow his train of thought, so he followed the murder weapon and asked, "Did the person you mentioned run with a hatchet in hand, or did he leave the hatchet behind?"

The man thought for a while and said, "Running with a hatchet in hand."

"What route did you run out of, and where did you go from, can you point it out?"

The man then randomly drew a line in the yard.

Jiang Yuan stepped forward to take a look, this is not right, the line you ran, there is no blood from the weapon.

Of course, the murderer can also wipe the blood from the knife wound.But what to use?My clothes are obviously too stupid, and the toilet paper I carry with me is probably not enough. Moreover, where do I throw the paper after wiping?Carrying it with you is another hassle.

If you really want to wipe the blood off the knife, the more appropriate solution is to use your own underwear, and then put it on after wiping.

But even if he did this, there must be a place for him to stay and change his clothes and pants.

Wu Jun waved his hand: "It's full of lies, take it back."

"I didn't lie, I didn't lie!" The man shouted loudly now.

The villagers who had gathered nearby for a long time slowly surrounded him.

The criminal police who were holding the suspect wisely stopped for fear of a drag.

Wu Jun said loudly: "Through our preliminary investigation, we currently believe that Liu Xiuying was chopped up by her husband. We have also collected DNA evidence. After returning to the police station, we will draw further conclusions based on the evidence. .”

The villagers were a little curious, stood still, wanted to say something, but didn't say anything, just looked at the men and criminal policemen in the circle.

The suspect got support, his waist became much stiffer, and he shouted again: "I'm not lying, you are arresting people randomly."

"The police can actually see a lot of things from the blood." Jiang Yuan turned around and entered the yard, preparing to teach the villagers a set of laws.

He is too familiar with these villages and villagers in Beiningtai.The villages here generally have ancestral halls, close social relations, and a tradition of fighting with weapons. Even in the face of power, they will not easily bow their heads.

On the other hand, the villagers are unreasonable when they talk about reason. To be precise, the village has its own set of reasons, and it doesn't mean that the village will worship it like a holy book just because you change a law outside.

Jiang Yuan could only choose their reasonable side, entered the yard, stood in front of the splattered blood, and said: "This is the place where the crime started. According to the shape of the blood, we can find that the victim's arm The location is here, and the murderer is holding a knife in his right hand..."

Jiang Yuan introduced what the splattered blood was like telling a story.

Then, Jiang Yuan came to the pool of blood again, and said in a slow voice: "After the victim was cut, she retreated to this position. She was in pain and very scared, and with the loss of blood, her strength decreased, and she might have given up. , so I sat here with my hands on the steps, and everyone can see the blood flow."

Jiang Yuan looked at the man again, and said, "The murderer is still waving his weapon at this time, so here, there are bloodstains like throwing..."

He pointed to the wall, and it was indeed dotted with little tadpoles.

Tadpoles formed by blood stains will release many tails at low speed or at a large angle.

At high speeds and small angles, its tails will unify into a thick spindle and a slender spindle.

All in all, bloodstain analysis started in the 50s, and it was quickly confused by research. A room full of blood is equivalent to countless delayed actions for people who are good at it, and there are many conclusions that can be given.

Jiang Yuan explained to the villagers how to analyze the bloodstains, and he didn't mind spending more time.

It's not just about teaching the law, it's also about solving problems.

Rather than send out a group of people from each side, scold and yell at each other, and persist for a few hours, relying on the anti-riot team to bring his side back, Jiang Yuan would rather take the time to tell everyone about the crime scene.

It is also a disguised form to report to Wu Jun and other colleagues about his ability in bloodstain analysis.

After all, they are all LV5 skills, and there will definitely be opportunities to use them in the future. Prove it now, and it will also help in the later work.

For the villagers, Jiang Yuan's explanation is the same thing. As time goes by, everyone's tough attitude will naturally tend to soften.

Since ancient times, the people did not fight with the officials. The villages in Beiningtai are relatively tough, but they are not fearless.

What should be afraid, is actually still afraid.

If it was a strong confrontation, the surrounding villagers would be more persistent.Now it has become a soft introduction, and the villagers are a little inexplicably peaceful.

In the end, under the watchful eyes of the villagers, Jiang Yuan completed a simple reconstruction of the crime scene—as far as case analysis is concerned, it was unnecessary.But he did it with ease, and the result was pleasing to all.

Except for the victim's husband.

When he was taken into a police car under the eyes of fellow villagers, he was on the verge of collapse.

He also knows now that although there is no camera to capture what he does, it is better than being captured by a camera.

The police have already determined that he was the one who hacked, and the victim’s husband couldn’t think of a reason to reverse the case, so he could only say angrily and fearfully: “My wife said she forgave me. I’ll just treat her well in the future. Why arrest me? Why arrest me?"

"Serious injury is criminal responsibility. It doesn't matter whether your wife pursues the responsibility or not." The criminal policeman who sat up with him gave him a disdainful glance.

"My wife broke her hand, and I was arrested again. What about my baby? Do you provide for me? Do you care?" The man struggled and twisted, his tone full of anger.

The criminal policeman held him down and shouted louder: "Your wife broke her hand, didn't you cut it off? Isn't it because you cut off your wife's hand that you are going to jail?"

The man's courage was at that moment just now, and now he was yelled at by the police, and he immediately shrank into a ball.

……

Jiang Yuan and Wu Jun each had a cigarette, sitting in a car without air conditioning, and the Zhonghua cigarettes were not so fragrant anymore.

In the end, what the man said was unreasonable, but it was indeed a problem.

Just weird and unreasonably weird.

Jiang Yuan can be regarded as gaining knowledge.

The old forensic doctor Wu Jun swallowed Zhonghua, and said in the smoke: "Although we have solved the case, the victim whose hand was cut off may not be grateful to us, but will scold us like that man."

Jiang Yuan nodded helplessly, probably knowing from the fact that the victim didn't name the murderer.

"But what we do is useful. We do forensic medicine, so we don't have to talk so much about the human world of the living. Speaking for the dead and injured, we will do our best to do our own thing well, so that there will be fewer unjust cases in the world. It is not in vain. The case, dead, dead to understand, live, to live clearly."

Jiang Yuan listened to Master's words, nodded earnestly, and said: "In our first class in college, the teacher said that the best thing about forensic medicine is to make people open-minded, and they are used to life and death. No problem is a problem, just live well. , stronger than anything."

Wu Jun was choked by his second-hand smoke, coughed a few times, and continued to praise: "Your blood analysis is really good, it's really solid, it shows that you have studied hard in class, and there are not many young people like you now. Come on, work hard, and you will definitely be better than Master and me in the future."

Jiang Yuan silently took out another pack of cigarettes and handed it to Master...
