Chapter 184: Jiang An's Meticulous Analysis
In an instant, everyone's gaze focused on Jiang An.
Even Zhang Yean and Wan, sitting nearby, were filled with surprise.
It had been less than half an hour since the three of them entered the office.
Within this half-hour, without systematically going through the case files, he could draw a clear conclusion!
You must know the cases that Mr. Zhang invited participation in are notoriously difficult to solve.
Moreover, it's certain that this case had been through thorough analysis by numerous criminal investigation experts repeatedly.
Jiang An junior's statement was a bit too reckless!
That was Zhang Yean's intuitive impression.
She even suspected whether Jiang An hadn't sobered up yet and was spouting nonsense here.
Subsequently, she quietly nudged him with her elbow.
Feeling the touch on his abdomen, Jiang An turned to look at Zhang Yean.
Where their eyes met, Jiang An confidently nodded.
He was using his gaze to tell her not to worry, that everything was under control.
At this moment, Wan was equally concerned.
His gaze wandered back and forth between Jiang An and Mr. Zhang several times.
During this time, he kept observing Mr. Zhang's expression.
Even though it was his first contact with Mr. Zhang, without knowing him well.
However, Jiang An could sense the suspicion on Zhang Feng's face.
Especially Sun Yiming, sitting diagonally opposite, showed blatant disdain.
As if he had no expectation for Jiang An's upcoming analysis.
At this point, Jiang An spoke with a deep voice, "Mr. Zhang, I just carefully reviewed the scene investigation photos and corpse examination photos."
"Next, I will briefly share my understanding from a forensic perspective."
"Firstly, from the forensic damage inference perspective, the damage on a victim's body is usually not fabricated."
"This is the accuracy of silent testimony!"
"For this particular body, the neck joints, thoracic vertebrae joints, lumbar joints, and both knee joints have injuries, and joint surface damage can be seen locally."
"Through analyzing these injuries, I believe the deceased must have experienced an impact from vertical conveyance violence from below."
"Moreover, I personally think this conveyance violence was very significant."
"Based on forensic injury deduction, I believe this violence originates solely from a fall from a high place."
"Furthermore, according to the relation between damage and fall height calculation, I reckon the fall point of this deceased was at least above the sixth floor."
As soon as the words fell, Zhang Feng nodded slightly.
He greatly appreciated the conveyance violence Jiang An just proposed.
"Conveyance violence," this technical term was proposed by a retired forensic expert at the last case discussion meeting.
Zhang Feng did not expect that such a young person could also recognize the existence of conveyance violence from a body.
Furthermore, reaching this level of analysis in such a short time is very remarkable!
You should know that the last time the retired forensic expert proposed this idea, it was after thoroughly studying the case files.
Then, Jiang An continued, "However, on this body, there indeed exist characteristics of traffic accident death."
"That is, the large area abrasions on the skin formed by the friction between the body and the ground."
"From this perspective, I believe there is parallel friction force between the body and the ground."
"As for the reason behind this friction force, I don't think it was formed by a traffic accident, but simply indicates that there was an initial velocity when the body contacted the ground."
"Initial velocity?"
"Initial velocity?"
Instantly, everyone was extremely surprised.
They didn't expect that such a professional term from physics would be used in case analysis, especially in the relationship between a body and the ground.
At this moment, Zhang Yean and Wan's hearts were pounding faster.
Both of them felt that Jiang An wasn't in a good state this afternoon, their palms sweating.
Sun Yiming, sitting opposite, looked at him and asked in a deep voice, "Comrade Jiang An, may I ask why do you think it's an initial velocity, rather than the result caused by a traffic accident?"
Jiang An answered, "We are no strangers to the body damage caused by traffic accidents."
"In cases of death caused by traffic accidents, the most common injury is collision damage."
"As the name suggests, it refers to the injury formed the instant the person being hit contacts the car's front."
"This collision injury usually results in fractures of the lower limbs of the deceased."
"Of course, if the offending vehicle is a large SUV or truck, it may also cause fractures in the waist or chest of the deceased."
Pausing slightly, Jiang An continued, "In cases of traffic accident death, besides bodily collision injuries, there are also throw injuries."
Then, he further explained, "At the moment of collision with the car's front, the body is thrown away by the immense impact force, forming a parabolic-like throwing process."
"After being thrown and landing on the ground, it creates friction with the ground, resulting in large area skin abrasions."
Jiang An flipped through the case files to the part on the corpse examination.
He glanced over it and continued, "On this body, we only see large area skin abrasions."
"However, we did not see fractures caused by collision."
"Therefore, I believe this body possesses some features of traffic accident damage but lacks typical characteristics of a traffic accident."
Finally, Jiang An concluded again, "Therefore, from my perspective, I only believe there was an initial velocity in the body's contact with the ground, not a traffic accident death."
Upon hearing this, Zhang Feng slightly lifted his eyelids.
