Chapter 528 Evidence Found
Driver's position!
In Chen Yan's eyes, the driver's position was a bit strange.
Taxi drivers spend most of the day sitting in a small cab, so in order to improve driving comfort, every taxi driver will adjust his or her seat to the most comfortable state.
However, there was something wrong with the victim's posture.
The victim's current posture was lying on the steering wheel, with his feet hanging down naturally, but his knees were pressed against the lower partition of the driver's station.
"Captain Wang, come here and help us!"
Wang Fenglei on the side was completely disappointed.
The personnel responsible for the investigation have thoroughly inspected the entire car and found no fingerprints, dander or hair on the door handles, carpets, door armrests, etc.
The murderer carefully cleaned up the scene just like he did more than ten years ago, leaving no clues behind.
However, when he saw Chen Yan observing the cab carefully, hope arose in his heart: "How's it going? Did you find anything?"
Chen Yan nodded, then shook his head: "I'm not sure yet. Captain Wang, help me carry the body."
"good!"
Although Chen Yan did not get a positive answer, it was obvious that Chen Yan had made some special discoveries.
Wang Fenglei leaned in from the side of the co-pilot, and Chen Yan worked on the left and right to straighten the driver's position.
Because the body was already a little stiff, the two of them spent a lot of effort.
"How's it going? Did you find anything?"
"have!"
This time, Chen Yan gave an affirmative answer.
After righting the driver in the driving seat, Chen Yan could clearly see the driver's current sitting posture.
Visual inspection showed that the distance between the driver's chest and the steering wheel was less than ten centimeters, and his hands were placed on the steering wheel with a large curvature.
This is not normal.
"Team Wang, look at the way this driver is sitting, isn't it a little strange?"
Who is Wang Fenglei?
Over the years, he has experienced dozens of cases, large and small. As soon as Chen Yan said it, he understood what was going on.
"The driver's sitting posture is a bit too far forward, and the curvature of the steering wheel held by his hands is too large, making it inconvenient to turn... Also, the distance between his legs and the driver's platform... is a bit too close."
Wang Fenglei's eyes lit up: "You mean, the murderer...drove this taxi before killing the deceased?"
As expected of Wang Fenglei, Chen Yan only mentioned the driver's sitting position before his death, and Wang Fenglei was able to grasp the most important clues.
"Yes, judging from the current posture of the driver's seat, this is definitely not the usual driving posture of the deceased. Therefore, it should be that the murderer drove to the cement factory by himself after subduing the deceased."
This point is also justified by the situation at the scene.
The cement factory has been relocated a long time ago. There is no human habitation within a kilometer radius here. How could a normal person take a taxi here in the early morning?
But if the murderer drove over, then everything would make sense.
"In addition, we found that the deceased had meticulously cleaned most parts of the car, including the meter, steering wheel and handbrake handle that the passengers would not touch at all."
"These parts are generally only touched by drivers. If the murderer was not driving, there would be no need to deal with the traces in these places."
"There is also the tightness of the handbrake. I just tried it and it was basically pulled to the limit."
"This extreme position will generally affect the service life of the handbrake wire. Taxi drivers will not care so little about their vehicles."
"Coupled with the sitting position of the deceased, it can be determined that the murderer once drove this car."
Wang Fenglei nodded and agreed with Chen Yan's judgment.
However, even so, will it be of any help to the investigation of the case?
You know, the investigators who were just in charge of collecting evidence not only collected evidence on the co-pilot and rear seats.
They also confirmed the main driver's parts, including the door handle of the main driver's door, the steering wheel and even the instrument panel. They all collected evidence, but still found nothing.
The murderer wiped down all parts of the car, erasing all traces.
Chen Yan naturally saw Wang Fenglei's doubts: "Although the other party cleaned up very well, there was one place that he couldn't clean up."
Um?
Wang Fenglei followed Chen Yan's gaze and asked, "Blood?"
Chen Yan nodded: "It's blood!"
"Judging from the amount of bleeding and the way the deceased was sitting, it was only after the murderer drove the car here that he inserted a probe into the deceased's carotid artery and bled, causing the taxi driver's death."
"In this process, he must have killed the deceased first and then cleaned up the traces."
Wang Fenglei nodded, there was no problem with this reasoning.
Because if the other party moved the deceased to the driver's seat and cleaned up the car before bleeding, he would definitely leave traces here when he committed the murder.
In that case, the killer would need to clean up a second time.
it's out of the question.
Therefore, the murderer must have moved the taxi driver to the driver's seat, inserted a probe to bleed him, and then started cleaning up the traces in the car.
"Comparing the blood volume of a normal person with the diameter of the probe... the whole process lasts about twenty minutes."
"This time interval should meet the murderer's need to clean up traces of the scene."
"However, there must have been a point in the process where the murderer couldn't clean up all the traces..."
Wang Fenglei also understood what Chen Yan meant at this moment: "The driver's seat carpet under the blood?"
"right!"
"Of course, if the murderer cleaned the driver's seat after leaving the driver's seat and before moving the driver to the driver's seat, it would be difficult to leave traces..."
"However, since the murderer did not return the adjusted seat to its original state, it shows that there were still some flaws in the murderer's crime."
The murderer could think of spraying the car with alcohol to eliminate the odor, and could also think of cleaning up his fingerprints, dander, hair and other traces. He was already one of the rare cautious players Chen Yan had ever seen.
Furthermore, cleaning up traces and killing people are about ten different consecutive actions.
It is not in line with normal people's thinking that the murderer first cleans up part of the car, kills people, and then cleans up other traces in the car.
Although the second murderer was thinking carefully, he still did not break out of the shackles of thinking inertia.
For example, subconsciously adjust the posture of the seat.
Every driver will feel a little uncomfortable when driving someone else's car, no matter how much the other person's adjusted seat position matches his or her usual driving habits.
Will subconsciously adjust the distance between the front and back of the seat and the angle of the backrest.
After driving the car, very few people restore the seats.
Even if some patients with obsessive-compulsive disorder recover, they will not return to their original state.
This is why many vehicles now come with seat memory functions.
"So, the murderer is most likely leaving clues under the driver's seat!"
Wang Fenglei nodded heavily.
Chen Yan's analysis is correct.
From behavioral and psychological analysis, similar conclusions can be obtained.
"The blood has not completely dried yet. We have to wait a little longer for the blood to coagulate before we can proceed with the next step of investigation!"
I'm waiting here, but the work can't stop.
Chen Yan has arranged for Liu Qingshan and the Shen City Detective Team to search for the trajectory information of the two taxis last night through the Sky Eye system.
Although Chen Yan knew that the murderer would most likely not show any flaws in this area, he could at least determine where the murderer got into the car through the trajectory range.
