Chapter 602: Repeating the Process

Taking samples of the things in the driver's seat again, and taking fingerprints and other traces, Jiang Yuan stood up, moved slightly away from the vehicle, took off his gloves, and while changing into new ones, observed the environment inside the driver's seat.

He directly activated the skills "Crime Scene Survey Temporary +1" and "Scene Reconstruction Temporary +1," which was equivalent to having an incomplete temporary LV6 scene reconstruction.

At this time, when Jiang Yuan looked at the scene inside the driver's seat again, more thoughts arose.

From the changes in the large area of fresh fingerprints, one could see the scene of the victim's hands groping around; from the excrement on her lower body, one could see the unconscious twisting of the body. In the final moments of life, the victim was not as many people said, dying peacefully. It was still accompanied by struggle and reluctance.

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

At the same time, Jiang Yuan also noticed that the victim left very few scratch marks at the seat belt buckle. A normal person's technique for opening and closing a seat belt should be pressing, and even if there are scratch marks, they shouldn't be full-hand scratch marks...

At this time, Jiang Yuan looked at the area near the seat belt with a purpose, and felt that there were too many traces left. A large number of fingerprints were normal, but there were a large number of skin dander residues, and greasy residues that seemed to be some kind of cosmetic.

Jiang Yuan leaned over into the driver's seat again, looked carefully at the seat belt buckle, took samples, and came out saying: "Take the buckle off later and put it in the evidence bag."

"Okay." The trace inspection responded immediately. Wan Baoming's mouth curled into a smile, saying: "Little Liu, you have to read the air."

Reading the air is a very Japanese expression, roughly equivalent to "having eyes for the situation."

Little Liu calmed down and thought slowly. Moreover, everyone hadn't realized Jiang Yuan's bug-level scene reconstruction skill, and didn't know what was playing a role at this moment.

How do you know you didn't make a mistake?

Lu Mao said: "The evidence I see now supports a locked-room murder, and the appraisal report you made has no problems, but if I were the person in charge of the scene survey, I don't know if I would reach the same conclusion..."

If you think a little more conspiratorially, the scene might have problems, the laboratory might have problems, and the person doing the appraisal might have problems.

"Yes. The vehicle was parked on an open road, and the exhaust gas produced by the engine would definitely be released to the outside world. Further survey verified that the vehicle had no defects and had not been illegally modified, so it excluded the possibility of exhaust gas entering the carriage during the emission process and causing personnel to be in the vehicle." Little Liu, whom Wan Baoming called, was 18 or 19 years old, his tone carrying full indifference to the workplace and leaders, and he wasn't afraid of being optimized.

Therefore, Jiang Yuan dared to express the above meaning: either you made a mistake, or we really encountered a locked-room murder.

Jiang Yuan nodded and said: "If that's really the case, then this case is truly a locked-room murder."

"No need, the protective clothing outside is sticky with many things." Jiang Yuan was talking about things like engine oil.

"If someone else did the scene survey, I would be useless." Jiang Yuan didn't feel he was very hard-working. If he was afraid of hardship, he could just ask someone to pry his mouth open to feed him.

In Wan Baoming's view, Little Liu obviously didn't read Jiang Yuan's implication.

"The driver who discovered the victim's death first dialed 120, and we were called over by 110." Little Liu's brow was tightly furrowed, saying: "When we arrived, the medical staff had already helped seal the scene. We also noticed the victim's skin was red, so we took measures to protect the scene for the first time. But how they did it specifically, we don't know."

"..."

Jiang Yuan looked at Wan Baoming's sincere face, then lowered his head, saying: "Forget it, I'd better change my protective clothing. It will be easier to talk when people come later."

Wan Baoming laughed, took out his phone that was hot from watching short videos, and smiled: "I'll call Little Liu and the others over. You sit and rest for a while?"

Jiang Yuan's implication had a bit of aggressiveness, also because he was too tired today, tired and hot, making him a bit impatient.

"This shows that carbon monoxide is emitted at a fixed point. It was only after the victim got in the car, fastened the seat belt, and started it, that the car was filled with carbon monoxide." Jiang Yuan paused and said: "So, it's not that there was already carbon monoxide in the car before the victim got in."

Either a locked-room murder really happened, or he missed something somewhere—this was actually Lu Mao's conclusion.

Jiang Yuan was clear, and the young technical police officer in front of him obviously didn't want to become the background board for a locked-room murder.

Wan Baoming is the director of the Criminal Science Center, essentially still a technician, so he couldn't help but ask: "What does this explain?"

As a criminal science technician, if you survey and survey, and the conclusion is a locked-room murder, it's really a bit ridiculous.

"This step needs to be re-checked." Jiang Yuan didn't pursue reasoning, nor did he pursue an exquisite way of solving the case. He was prepared to follow the timeline, repeat the process step by step, and then see if the result would jump out by itself.

Jiang Yuan checked all the traces in the car, and checked the outside of the car, and even the trunk and the bottom of the car, thoroughly. After everything was done, a whole afternoon had passed.

"Before the victim got in the car, she fastened the seat belt, and then, she felt breathing difficulties."

"Tell me about it." Jiang Yuan said.

Wan Baoming didn't know much about this case, just nodded slightly.

If it was the former situation, the victim would probably not even have time to fasten the seat belt before feeling breathing difficulties.

I understand in my heart that Jiang Yuan is still questioning my work, but after the conversation just now, I have to question it myself.

Little Liu fell into deep thought again.

After bathing and changing, and coming out, the two technicians responsible for vehicle appraisal had already arrived.

Little Liu suddenly realized that what he could think of, Jiang Yuan obviously wouldn't fail to think of.

Everyone had just watched Jiang Yuan work, and basically could grasp his thoughts, but following someone else's observation and observing it actively oneself were two different concepts.

The other technician specifically said: "We made inquiry transcripts for the medical staff."

How do you know if there was a problem in some link?

Little Liu let out a sneer, then realized that Jiang Yuan and Wan Baoming didn't laugh, so he couldn't help but restrain his smile.

Change to another technician, or another expert, nine times out of ten, they wouldn't dare to reach such a conclusion.

It was only then that he dared to take off his hat and let the sweat flow down.

And Lu Mao's initial judgment was consistent with Little Liu's judgment, but it didn't mean that Jiang Yuan agreed with Little Liu, but that he excluded all other possibilities through scene reconstruction, scene survey, and various other means.

Jiang Yuan himself is a technician, and he is not wordy. He greeted them, got to know each other, and asked: "I looked at your previous appraisal, saying that no suspicious items containing carbon monoxide or causing carbon monoxide production were found inside or outside the car, and the scene didn't have the conditions to produce carbon monoxide?"

Rather than young people in the same village who sweat in the gym every day, he would rather sweat at the crime scene. In return, the young people in the village get strong muscles, and he can execute a village's criminals. Everyone will be very happy.

Jiang Yuan came out of the car for the second time and said slowly.

The Jiang Yuan who asked himself questions today is not a weak chicken leader from somewhere, but Ningtai Jiang Yuan!

Wan Baoming looked at Lu Mao's "miserable state" and pretended to be distressed, saying: "Team Leader Jiang is too hard-working. Sigh, really should let the media see. You have such a big reputation, and you still have to do it to this extent."

"Director Wan, can you ask the technician who did the vehicle test before to come over." Lu Mao was sweating profusely, and the sweat beads fell directly from his head.

Even the other technician who came with him was a bit impatient before Little Liu spoke again: "If there is a problem, it should have happened in the link before we arrived."

This time, Little Liu thought for a long time.

"Director Wan, can you ask the technician who did the vehicle test before to come over." Lu Mao was sweating profusely, and the sweat beads fell directly from his head.

Judicial criminal investigation personnel, who have come into contact with many cases, basically don't believe in any locked-room murders.

Some cases are indeed very difficult to solve, and can even be declared unsolvable. But this is usually not a perfectly designed case; more often, it is just a lack of investigation means, or the investigation stage has problems, it's just not good to announce it to the public.

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

Wan Baoming finished the call and stretched out his phone, saying: "Don't say, I couldn't help but write a few poems while waiting for you just now. Since I have time, please appreciate them?"

He had already conducted a careful survey, from the victim's cause of death to the environment the victim was in. If all were like this, then it really was a locked-room murder. ===== CHAPTER 603 =====
