At this moment, at the entrance of Jiangcheng Police Station.
The family of the deceased, Li Rui, are standing under the scorching sun, and their anger is rapidly mounting.
Even the media reporters at the entrance want to take the opportunity to vent online.
"Come on! Let the chief come out!"
"Give us an explanation!"
"My daughter couldn't have committed suicide!"
"Punish the murderer and give us justice."
"The truth! All we want is the truth."
...
For a moment, the family's emotions grew increasingly agitated, and their shouting grew louder.
The security guards and stationed officers on either side of the entrance stepped forward to intervene.
"Please be aware that this is a workplace."
"Otherwise, we can detain you for disrupting normal work order."
....
"I don't care!"
"I want to see your chief."
...
Faced with these family members, unless absolutely necessary, police equipment must not be used.
Otherwise!
It can only exacerbate the conflict.
However, considering the family's agitation is due to the sudden death of their daughter.
The overseeing officers stabilized the family's emotions while calling to report to their superiors.
Perhaps it was because the family's voices were too loud.
Or maybe the meeting room of the investigative team was closer to the entrance.
Captain Li Jian could faintly hear the family's shouting.
This is really reaching a critical point.
Unconsciously, Captain Li Jian quickened his pace of smoking.
In moments of tense pressure like this, cigarettes are the best companion.
Even though the family is clamoring to find the chief, the ultimate pressure rests on the investigative team.
Ultimately, it will fall on Captain Li Jian's shoulders.
In the meeting room, the originally set conclusion was unexpectedly challenged.
This made Captain Li Jian feel even more stressed.
Of course, if it was a typical rookie questioning, Captain Li Jian would probably just smile and not take it to heart.
But!
Jiang An is not an ordinary person.
He was a person who scored full marks in every subject during university.
Just for this point.
Captain Li Jian felt it necessary to give him a chance to speak.
In the meeting room, besides the tech team, no one from the investigative team knew Jiang An.
Some people began whispering.
Where does he come from?
Why haven't we seen him before?
He looks so young, is he an intern?
Really doesn't understand the rules, you should be humble when coming to intern.
Why show off in this case?
Mr. Ma is still waiting for our conclusion to handle the case.
.....
At this crucial moment, hearing such discordant voices.
Many in the investigative team had a bad impression of Jiang An.
At this moment, Captain Li Jian said in a low voice: "Oh?"
"Our investigation requires evidence."
"Discuss your basis and reason."
When he said this, Captain Li Jian did not have high hopes.
After all, he's a newly joined rookie, even if his theoretical knowledge is rich.
There is still a certain gap between practice and theory.
Letting him speak was merely giving the rookie a chance to showcase himself.
Instantly, other investigative team members slumped in their chairs like wilted cucumbers.
Their already exhausted bodies had no mood to listen to a rookie's chatter.
It's really unimaginable for a rookie to just look at photos and determine the nature of the case.
It's simply a fantasy!
If investigative work were this easy, most people wouldn't go on field investigations in bitter cold and scorching heat.
The senior sister sitting next to Jiang An tugged at his sleeve.
However, Jiang An hesitated not a bit.
He pointed at the photos on the projector and said in a low voice: "Mr. Li, the reason why I think this deceased didn't commit suicide is mainly for the following three reasons."
"Firstly, according to our forensic textbooks, hanging is not immediate death but involves about 1-2 minutes of struggle."
"During this 1-2 minutes, the deceased should not just be hanging there motionless but continuously struggling, possibly kicking their feet wildly."
"Especially, when the deceased's hands are not restrained, the hands would clutch at things everywhere."
"Now, please see this original photo."
"The position where the deceased hanged is under a willow tree."
"From this photo, we can see that this willow tree is very dense."
"For the deceased Li Rui, there are many dangling willow branches within reach."
"In a typical hanging process, if Li Rui had struggled during the process, then why are there no signs of the willow branches being damaged?"
"We can even overlook whether Li Rui's hands were grasping at the willow branches."
"But there aren't even fallen willow leaves below the corpse."
"Is this normal?"
As he finished speaking, many old detectives moved slightly in their seats.
Seems he has a point.
This young man has some skills!
A few investigative team members began discussing quietly.
Captain Li Jian was also taken aback.
The reason for his surprise wasn't just Jiang An's perspective, but the impact on the earlier suicide conclusion.
Just as everyone was surprised and puzzled, Jiang An continued his analysis.
"Secondly, as just mentioned, during a person's hanging, there are manifestations of struggling."
"This is not only manifested in limb movements but also at the point where the rope hangs."
Is there scrutiny at the point where the rope hangs?
I haven't heard such a viewpoint in police academy.
Was I daydreaming when the professor mentioned this?
Two young detectives murmured softly.
Under everyone's gaze, Jiang An continued: "Using common knowledge, we can imagine the swing game we've played before."
"When we sit on the swing board and swing, there's a strong friction process at the upper end of the swing rope."
"If the swing rope is metal, we can often hear the squeaking friction sound."
Many people related common knowledge and unconsciously nodded their heads.
Jiang An continued: "Please Wan get the photo of the rope hanging point."
"Ah? Okay!"
Wan was completely engrossed earlier and almost didn't notice Jiang An calling.
Then, Wan moved the mouse and clicked to open the photo.
The photo is very clear!
Jiang An analyzed and said: "Mr. Li, please look."
"The black rope hanging at the neck of the deceased is very thin."
"According to our middle school physics regarding pressure and contact area, the smaller the contact area, the greater the pressure."
"Which is the formula P=F/S."
"The deceased Li Rui's body is slightly plump, estimated at around 100 jin."
"In such a weight situation, tying such a rope, plus the struggle of the hanged person, would definitely create deep friction marks at the point where the rope hangs."
Jiang An spread his hands.
"However, it is unfortunate!"
"We can see with the naked eye that there are no obvious friction marks where the rope is tied."
Finally, Jiang An concluded: "Through the above two points of analysis, I infer that the deceased did not struggle at all when hanging on the willow tree."
"To be accurate, I believe she was hanged on the tree after death."
As soon as the words fell, an older detective questioned: "The cause of death is asphyxiation, how is it not hanging?"
Jiang An remained unfazed and said in a deep voice: "From a forensic perspective, the deceased indeed had signs of asphyxiation."
"However, compression of the neck is not the sole reason."
