Chapter 630 Repeat Process
After re-sampling the things in the main cab, and taking fingerprints and other traces, Jiang Yuan got up, a little far away from the vehicle, took off his gloves, and observed the environment in the cab while changing them to new ones.

He directly opened 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 again, more thoughts arose.

From the changes in the large area of ​​fresh fingerprints, we can see the scene where the victim's hands are groping around, and from the excrement of her lower body, we can see the unconscious distortion of the body.In the final moments of life, the victim did not die peacefully, as many have suggested.Still accompanied by struggle and reluctance.

In this world, a truly peaceful death is rare, very rare.

The victim's body was finally tilted 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 normal way of opening and closing the seat belt should be pressing. Even if there are scratches, it should not be the scratches of the whole hand...

At this time, Jiang Yuan looked around the seat belt with purpose, and felt that there were too many traces left.A lot of fingerprints is normal, but a lot of flakes, and what seems to be a greasy residue of some kind of cosmetics.

Jiang Yuan leaned into the main driver again, carefully looked at the buckle of the seat belt, took a sample, and said, "Take off the buckle of the seat belt in a while, and put it in the evidence bag."

"Okay." The trace inspection here responded immediately.

Everyone watched Jiang Yuan do things just now, and they can basically figure out his thoughts, but what they see by following others and what they see by themselves are two different concepts.

Moreover, everyone has not realized Jiang Yuan's BUG-level on-site reconstruction skills, and they don't know what effect it is playing at this moment.

"After the victim got into the car, he put on his seat belt, and then he felt difficulty breathing."

After Jiang Yuan got out of the car for the second time, he said slowly.

Wan Baoming is the director of the criminal center, and essentially a technician, so he couldn't help but ask, "What does this mean?"

"It means that carbon monoxide is emitted at a fixed point. After the victim got in the car, put on 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 into the car again."

If the latter is the case, the victim probably has no time to wear a seat belt, and will feel difficulty breathing.

Wan Baoming didn't know much about the case, so he just nodded slightly.

Jiang Yuan checked all the traces inside the car, and then thoroughly checked the outside of the car, even the trunk and the bottom of the car. Everything was done, and an afternoon passed.

"Director Wan, can you invite the technician who did the vehicle inspection before?" Jiang Yuan was sweating profusely, beads of sweat falling directly from his head.

It was at this time that he dared to take off his hat to let the sweat flow down.

Looking at Jiang Yuan's "miserable appearance", Wan Baoming couldn't help pretending to feel distressed, and said: "Team Jiang has worked too hard, alas, I really should show the media, you are so famous, and you still have to do it in the end." to this extent."

"If someone else does the on-site survey, I'm useless." Jiang Yuan himself didn't feel how hard it was. If he was afraid of suffering, he could ask someone to eat with his mouth open.

Rather than sweating in the gym every day like some young people in the same village, he would rather sweat at the crime scene. Looking back, the young people in the village have gained strong muscles, and he can execute criminals in a village. Everyone will be very happy.

Wan Baoming laughed haha, then took out his hot phone while watching short videos, and said with a smile: "I called Xiao Liu and the others to come over, why don't you sit and rest for a while?"

"No need, a lot of things are 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 cell phone and said, "Don't tell me, I couldn't help but write a few poems when I was sitting waiting for you just now. I just have time. Would you like to taste one or two?"

Jiang Yuan looked at Wan Baoming's sincere face, then lowered his head, and said, "Forget it, I'd better change the protective clothing, and we can talk when someone comes."

After Jiang Yuan finished speaking, he went straight to the bathroom.

After taking a bath and changing clothes, when I came out again, I saw that two technicians in charge of vehicle identification had arrived.

Jiang Yuan himself is a technician, so he didn't talk too much, so he said hello, got to know each other, and asked, "I saw your previous appraisal, saying that there were no suspicious items containing carbon monoxide or causing carbon monoxide to be found inside or outside the car. Don't have the conditions to produce carbon monoxide?"

"Yes. The vehicle is parked on the open road, and the exhaust gas produced by the engine is normally released to the outside world immediately. Further investigations have found that the vehicle has no defects and has not been illegally modified, so the exhaust gas is excluded during the exhaust process. Entering the compartment will cause the possibility of vehicle occupants." The Xiao Liu mentioned by Wan Baoming is a 37-year-old Xiao Liu, and his tone shows that he doesn't care about the workplace and leaders, and he is not afraid of optimization.

Jiang Yuan nodded and said, "If that's true, this case is really a murder in a secret room."

He had already done a careful investigation, from the cause of the victim's death to the environment the victim was in. If this was the case, then it was really a secret room murder.

Xiao Liu sneered subconsciously, and then found that neither Jiang Yuan nor Wan Baoming was smiling, so he couldn't help but suppress his smile.

The criminal investigators of the judiciary have been exposed to many cases, and they don't believe in secret room murders at all.

Some cases are indeed difficult to detect, and can even be declared undetectable.But that is usually not a perfectly designed case. More, it is just that the means of investigation are lacking, or there is simply a problem in the investigation stage, but it is not easy to announce it to the public.

Xiao Liu suddenly realized that what he could think of, Jiang Yuan obviously couldn't miss it.

The Jiang Yuan who asked himself today was not a weak leader from anywhere, but Jiang Yuan from Ningtai!

A smile appeared on the corner of Wan Baoming's mouth, and he said, "Xiao Liu, you have to understand the air."

Understanding the air is a very Japanese expression, which is roughly equivalent to "have eyesight".

From Wan Baoming's point of view, Xiao Liu obviously didn't understand Jiang Yuan's meaning.

Xiao Liu calmed down and began to think slowly.

"You actually want to ask, what is the reason that makes the case look like a murder in a secret room?" Xiao Liu asked tentatively.

Jiang Yuandao: "The evidence I have seen now supports the murder in a secret room, and the appraisal report you made is also fine, but if I were the person in charge of the on-site investigation, I don't know if I would come to the same conclusion... "

Jiang Yuan's language was more or less aggressive, and it was also because he was too tired today, tired and hot, which made him a little impatient.

As a criminal science technician, it would be a bit ridiculous if the investigation came and went and the conclusion was that the murder was done in a secret room.

Jiang Yuan believes that the Liu technician in front of him is also unwilling to be the background board for a murder in a secret room.

Xiao Liu fell into the long exam again.

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 murder in a secret room really happened, or he made some omissions somewhere - this is actually Jiang Yuan's conclusion.

Another technician, or some other expert, would dare not come to such a conclusion in all likelihood.

How do you know you are right?

How do you know that it is not in a certain link, what is the problem?
If you think about conspiracy theories, there may be problems at the scene, there may be problems with the laboratory, and there may be problems with the person who identified it.

However, Jiang Yuan's initial judgment was consistent with Xiao Liu's judgment, which does not mean that Jiang Yuan agreed with Xiao Liu, but that he ruled out all other possibilities through on-site reconstruction, on-site investigation and other means.

That's why Jiang Yuan dared to express the following meaning: Either you made a mistake, or we really encountered a secret room and killed people.

This time, Xiao Liu thought for a long time.

The other technician who came with me was a little impatient, so Xiao Liu spoke again and said, "If there is a problem, it should have happened before we arrived."

"Tell me." Jiang Yuan said.

"The driver who discovered the victim's death 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 took immediate measures to protect the scene. But we don’t know exactly how they did it.”

The technician next to him specifically said: "We made an inquiry record for the medical staff."

"This step can be re-examined." Jiang Yuan does not pursue reasoning, nor does he pursue sophisticated ways to solve the case. He is going to follow the timeline, repeat the process step by step, and then see if the result will satisfy him. jump out.
