Chapter 630 Repeat process
After resampling the contents of the main cab and taking fingerprints and other traces, Jiang Yuan stood up, stood a little further away from the vehicle, took off his gloves, replaced them with new ones, and observed the environment in the cab.
He directly activated the skills, "Crime Scene Investigation Temporary +1" and "Scene Reconstruction Temporary +1", so it was equivalent to an incomplete temporary LV6 scene reconstruction.
At this time, when Jiang Yuan looked at the scene in the cab, more thoughts arose.
From the changes in the large area of fresh fingerprints, you can see the victim's hands groping around, and from the excrement on her lower body, you can see the unconscious distortion of the body. In the last moments of his life, the victim did not die peacefully as many people said. Still accompanied by struggle and reluctance.
In this world, a truly peaceful death is rare and rare.
The victim's body eventually leaned to the left, indicating that she wanted to get out of the car.
At the same time, Jiang Yuan also noticed that the victim left very few scratches on the buckle of the seat belt. The way a normal person opens and closes a seat belt should be by pressing. Even if there are scratches, they should not be scratches all over the hands...
At this time, Jiang Yuan carelessly looked around the seat belt again and felt that there were too many traces left behind. A large number of fingerprints is normal, but a large amount of dandruff residue and greasy residue seem to be the residue of some kind of cosmetics.
Jiang Yuan leaned into the driver's seat again, carefully looked at the buckle of the seat belt, took a sample, and said, "I'll take off the buckle of the seat belt later and put it in the evidence bag."
"Okay." The trace inspection here responded immediately.
Everyone just watched Jiang Yuan do what he was doing and could basically figure out what he was thinking. However, what others saw and what they saw on their own initiative were two different concepts.
Moreover, no one is aware of Jiang Yuan's BUG-level on-site reconstruction skills, and they don't know what role they are playing at this moment.
"After the victim got into the car, he put on his seat belt, and then he felt difficulty breathing."
Jiang Yuan got out of the car for the second time and said slowly.
Wan Baoming is the director of the Criminal Investigation Center and is essentially a technician. He couldn't help but ask: "What does this mean?"
"It shows that carbon monoxide is emitted at fixed points. After the victim got into the car, fastened his seat belt, and started the car, the car was filled with carbon monoxide." Jiang Yuan paused and said: "So, it's not that there is already carbon monoxide in the car. The victim got in the car again.”
If it is the latter situation, the victim may not even have time to fasten his seat belt before he will feel difficulty breathing.
Wan Baoming didn't know much about this and only nodded slightly.
Jiang Yuan finished checking all the signs inside the car, and thoroughly checked the outside of the car, as well as the trunk and bottom of the car. After everything was done, an afternoon passed.
"Director Wan, can you please invite the technician who did the vehicle inspection before?" Jiang Yuan was sweating profusely, and beads of sweat fell directly from his head.
It was then that he dared to take off his hat and let the sweat flow down.
Wan Baoming looked at Jiang Yuan's "tragic look" and couldn't help but pretend to be distressed and said: "Captain Jiang has worked too hard. Hey, you really should show it to the media. You are already so famous, but you still have to do this." To this extent.”
"If we let others do the on-site investigation, I will be useless, right?" Jiang Yuan himself didn't feel it was very hard. If he was afraid of hardship, he could just ask someone to open his mouth to eat.
Instead of sweating in the gym every day like some young people in the same village, he would rather sweat at the crime scene. Later, the young people in the village got strong muscles, and he could execute the criminals of a village. Everyone will be happy.
Wan Baoming laughed loudly, then took out his phone, which was getting hot from watching short videos, and said with a smile: "I'll call Xiao Liu and the others to come over. Why don't you sit down and rest for a while?"
"No need, there are a lot of things stuck to the protective clothing outside." Jiang Yuan was talking about things like engine oil.
After Wan Baoming finished the call, he stretched out his phone and said, "Don't tell me, I couldn't help but write a few poems while I was sitting waiting for you. I happen to have time, could you please taste them?"
Jiang Yuan looked at Wan Baoming's sincere face, then lowered his head and said, "Forget it, I'd better change into the protective clothing. People will come later so we can talk more easily."
After Jiang Yuan finished speaking, he went straight to the bathroom.
After showering and changing clothes, when I came out again, I saw that two technicians responsible for vehicle appraisal had arrived.
Jiang Yuan himself is a technician, so he didn't say anything. He said hello and got to know each other, and then asked: "I saw your previous identification, saying that no suspicious items containing carbon monoxide or causing carbon monoxide were found inside and outside the car. There was also no suspicious items at the scene. Don’t you have the conditions to produce carbon monoxide?”
"Yes. The vehicle is parked on an open road, and the exhaust gas produced by the engine will normally be released to the outside world immediately. Further investigation has confirmed that the vehicle has no defects and has not been illegally modified, so it is ruled out that the exhaust gas is emitted during the emission process. Entering the carriage may cause damage to vehicle personnel." The Xiao Liu Wan Baoming refers to is a thirty-seven or eight-year-old Xiao Liu, with a tone of indifference to the workplace and leadership, and a sound of not being afraid of optimization.
Jiang Yuan nodded and said: "If this is indeed the case, this guy really committed a secret room murder."
He has done a careful investigation, from the cause of death of the victim to the environment of the victim. If this is the case, then it is really a secret room murder.
Xiao Liu subconsciously sneered, and then found that neither Jiang Yuan nor Wan Baoming was laughing, so he couldn't help but restrain his smile.
The criminal investigators of the judicial agencies have been exposed to too many cases and do not believe in secret room murders at all.
Some cases are indeed difficult to detect and can even be declared undetectable. But it is usually not a perfect piece of software designed. More often, it is just that the investigation methods are expensive, or simply there is a problem during the investigation stage, but it is just difficult to announce it to the outside world.
Xiao Liu suddenly realized that Jiang Yuan would obviously not think of anything he could think of.
The Jiang Yuan who asked himself what he was talking about today was not some weak leader from anywhere, but Ningtai Jiang Yuan!
A smile appeared at the corner of Wan Baoming's mouth and he said: "Xiao Liu, you have to read the air."
Reading the air is a very Japanese expression, roughly equivalent to "having an eye for money".
In Wan Baoming's opinion, Xiao Liu obviously didn't understand Jiang Yuan's meaning.
Xiao Liu calmed down and began to think slowly.
"Actually, you want to ask, what is the reason that makes this case look like a secret room murder?" Xiao Liu asked tentatively.
Jiang Yuandao: "The evidence I see now supports secret room murder, and the identification report you made is fine, but if I were the person in charge of the on-site investigation, I don't know if I would reach the same conclusion... "
Jiang Yuan's tone was more or less aggressive. He was too tired today, tired and hot, which made him a little impatient.
As a criminal science technician, if after repeated investigations, the conclusion is that there was a secret room murder, that would be a bit ridiculous.
Jiang Yuan believed that the technician Liu in front of him did not want to become the background of a secret room murder.
Xiao Liu once again fell into a long exam.
He knew in his heart that Jiang Yuan was still questioning his work, but after the conversation just now, he had to question it himself.
Either a secret room murder really took place, or he made an omission somewhere - this is actually Jiang Yuan's conclusion.
Another technician or other expert would most likely not dare to come to such a conclusion.
How do you know you didn't make a mistake?
How do you know if there is something wrong in a certain link?
If you think a little bit more about conspiracy theories, there may be problems at the scene, there may be problems in the laboratory, and there may be problems with the person who made the appraisal.
Jiang Yuan's initial judgment was consistent with Xiao Liu's, which does not mean that Jiang Yuan agreed with Xiao Liu, but that he eliminated all other possibilities through various means such as on-site reconstruction and on-site investigation.
Therefore, Jiang Yuan dared to express the following meaning: Either you made a mistake, or we really encountered a secret room murder.
This time, Xiao Liu thought for a long time.
Another technician who came with him was a little impatient, so Xiao Liu spoke again and said: "If there is going to be a problem, it should happen before we arrive."
"Tell me about it," Jiang Yuandao said.
"The driver who found the victim dead first dialed 120, and we called 110." Xiao Liu frowned tightly and said, "When we arrived, the medical staff had already cordoned off the scene. We also noticed that the victim's skin was red, so we immediately took measures to protect the scene. But we don't know exactly how they did it."
The technician next to him said specifically: "We made an inquiry record for the medical staff."
"This step can be rechecked." Jiang Yuan did not pursue reasoning, nor did he pursue exquisite ways to solve the case. He was going to follow the timeline, repeat the process step by step, and then see if the result would be the same. Jump out on your own.
