The victim's husband also noticed that Wu Jun and Jiang Yuan seemed to be disbelieving, 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 a splash injury, but if you block it a few times, you will get a few splashes, unless there is no injury.
Wu Jun and Jiang Yuan laughed even more weirdly.
This shows that the person in front of me knows nothing about bloodstains.
As we all know, splash injuries are very easy to see. If you want to simulate it, just hold a cup of blood... If you don't have it, you can also use urine instead. Fill a large cup and pour it on the white wall. This will reveal the injury.
Blood stains or yellow urine stains are what a splash injury looks like.
Of course, if you only want to see it for a short time, you can use water instead.
The man in front of him was obviously telling lies with his eyes open. Although there was blood where he was pointing, it did not look like blood from a splatter injury at all. This was not immediately revealed.
You don't even know how to learn bloodstains, but you still dare to kill people?
The development of the modern criminal investigation field has long raised the threshold for violent crimes.
If you run away after cutting it, it may take some time for the police to lock down the suspect. Now you are back at the crime scene as a witness, and you don’t even have any foundation in bloodstain science, so how can you make it up?
Wu Jun raised his chin and signaled to the two criminal policemen behind him.
The detectives who appeared on the scene were smarter than dogs. They wrinkled their noses, looked at each other's companions with the corner of their eyes, then took two steps forward at the same time, and immediately grabbed the man's arm.
"Don't move." The old policeman here said, and the younger Kaka put on the handcuffs.
The cold handcuffs are a little heavy, as if they are being forced to hold the handle.
The victim's husband's face turned a brown color.
"I really am... I just blocked the knife. Why are you arresting me?" The victim's husband struggled uneasily for a few times and wanted to call someone, but he didn't dare to.
The rural areas in Beiningtai are very particular about unity. Including Jiangcun, 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 it, you can ask a portrait master and I will tell you what that person looks like."
Naturally, Wu Jun would not follow his train of thought, so he followed the murder weapon and asked, "Did the person you mentioned run away holding a hatchet, or did he drop the hatchet and run away?"
The man thought for a moment and said, "He ran away with a hatchet in his hand."
"How did you run out? Where did you run from? Can you point me to where?"
The man then randomly drew a line in the yard.
Jiang Yuan stepped forward and took a look. This was wrong. There were no blood stains from weapons on the line you were running on.
Of course, the murderer could also wipe the blood from the knife wound. But what should he use to wipe it with? His clothes are obviously too short, and the toilet paper he brought with him may not be enough. Moreover, where to throw the paper after wiping it? With him.
Carrying it around is another hassle.
If you really want to wipe the blood from the knife, the more appropriate solution is to use your own underwear and put it on after wiping it. This will not affect your movements and will not be easily noticed by others on the road.
But even if he does this, there must be a place for him to stay and change his clothes.
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.
The villagers who had already gathered nearby slowly gathered around.
The detective holding the suspect was afraid of being pulled, so he wisely stopped.
Wu Jun said loudly: "Through our preliminary investigation, we currently believe that Liu Xiuying was stabbed by her husband. We have also collected DNA evidence. When we return to the police station, we will make further conclusions based on the evidence."
.”
The villagers were a little curious and stood still. They didn't say anything if they wanted to say anything. They just looked at the men and detectives in the circle.
The suspect received support, became much more rigid, and shouted again: "I didn't lie, you are arresting people randomly."
"The police can actually see a lot of things from the blood stains." Jiang Yuan turned around and entered the yard, preparing to educate the villagers on the law.
He is very familiar with these villages and villagers in Beiningtai. The villages here generally have ancestral halls, close social relations, and a tradition of fighting. Even in the face of power, they will not bow easily.
On the other hand, the villagers are not unreasonable when it comes to reasoning. To be precise, the village has its own set of principles, and the village will not treat it as 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: "Where the hair begins here, based on 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 splatter-like blood stains were like telling a story.
Then, Jiang Yuan came to the pool of blood again and said slowly: "After the victim was chopped, she retreated to this position. She was in pain and very scared. With the blood loss, her strength decreased, and she may have given up."
, so I sat here with my hands on the steps, and everyone can see the blood flowing."
Jiang Yuan looked at the man again and said: "The murderer was still waving weapons at this time, so here, there are fluttering blood stains..."
He pointed at the wall, and it was indeed dotted with tadpoles.
The tadpoles formed by blood stains will release many tails at low speed or large angle.
At high speeds and small angles, its tail will merge into one, and then become a thick spindle shape, and a slender spindle shape.
All in all, bloodstain analysis started in the 1950s and was quickly studied to death. 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 drawn.
Jiang Yuan told the villagers how to analyze blood stains and did not care about spending more time.
This is not only popularizing the law, but also solving problems.
Instead of sending a group of troops from each side, yelling at each other, persisting for several hours, and then relying on the riot squad to take their side back, Jiang Yuan would rather spend time telling everyone about the situation at the crime scene.
It was also a disguised form of reporting to Wu Jun and other colleagues on his ability in blood stain analysis.
After all, these are LV5 skills, and there will definitely be opportunities to use them in the future. Proving them now will also help with later work.
For the villagers, Jiang Yuan's explanation is the same thing. As time goes by, everyone's tough attitude will naturally soften.
Since ancient times, people have not fought with officials. The people in Beiningtai's village are relatively tough, but they are not fearless.
You should be afraid, but you are still afraid.
If it was a strong confrontation, the villagers who came around would be able to hold on. Now it has become a soft introduction, and the villagers are inexplicably peaceful.
In the end, Jiang Yuan, with the villagers watching, completed a simple reconstruction of the crime scene. It was not necessary for situation analysis. But he did it easily, and the result made everyone happy.
Except for the victim's husband.
When he was taken into the police car under the eyes of his fellow villagers, his whole body was close to collapse.
He also knows now that although there is no camera to capture what he does, it is better than having it captured by a camera.
The police have determined that he was the one who chopped it. The victim’s husband could not think of a reason to sue. He could only say with anger and fear: "My wife said she forgives me. I just need to be nice to her in the future. You guys
Why are you arresting me? Why are you arresting me?"
"Severe injuries are criminal liability, and it doesn't matter whether your wife holds you accountable." The detective who sat down with him glanced at him disdainfully.
"My wife's hand was broken and I was arrested again. What will happen to my baby? Do you provide food? Do you care?" The man struggled and twisted, his tone full of anger.
The criminal policeman held him down and shouted louder: "Your wife's hand is broken, wasn't it cut off by you? Isn't it because you cut off your wife's hand that you are going to jail?"
The man's courage was just that moment ago, but 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, the Chinese cigarettes were not that fragrant.
What the man said in the end made no sense, but it was indeed a problem.
It's just weird and unreasonable.
Jiang Yuan has become more knowledgeable.
The old forensic doctor Wu Jun swallowed the Chinese and said in the smoke: "Although we have broken the case, the victim whose hand was cut off may not be grateful to us. Instead, he will scold us like the man."
Jiang Yuan nodded helplessly, and he roughly knew it from the fact that the victim didn't tell the murderer.
"But what we do is useful. We are practicing medicine and we don't have to talk about the human world so much. For the dead and injured, we will try our best to do our own thing well and let there be less injustice in the world.
Bai Zhigu, when you die, you have to understand clearly, and when you live, you can live clearly."
Jiang Yuan listened to the master's words, nodded seriously, 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 get used to the alternation of life and death. No problem is a problem. Live well.
, better than anything else.”
Wu Jun choked on his own second-hand smoke, coughed a few times, and continued to praise: "Your blood stain analysis is really good and solid. It shows that you listened carefully in class and studied hard. There are not many young people like you nowadays."
Come on, work hard and you will definitely be better than me, Master."
Jiang Yuan silently took out another pack of cigarettes and handed them to the master...
