Suspect.
Or the word witness.
Perhaps none of these can accurately describe the second person who is quite special in this case.
It's certain.
In the short period of time after falling from the building, she cut the deceased's radial artery and caused secondary injury.
but.
According to the warm scene on the rooftop tablecloth and the letter left by the deceased.
She's more like...
The only friend who accompanied the deceased on his last journey.
But no matter what identity it is.
If you want to get to the bottom of this case, you must find this person.
......
now.
At Su Ming's reminder.
Xu Changsheng reacted immediately and indeed looked at the current details.
The suspect who witnessed the deceased falling from the building.
There is a high possibility that he committed suicide, otherwise why would he just erase the footprints?
at the same time.
Xu Changsheng also considered another point.
Even though both children were neglected and bullied by the people around them, it was not easy for them to make the decision to commit suicide.
Not to mention that both of them made this decision.
Does this mean that...
Just as Su Ming guessed, there was actually a big hand behind the fall, inducing and controlling everything.
Didn't think about it for too long.
Xu Changsheng immediately walked up a few steps and greeted them at the entrance of the rooftop.
"Xiao Ming."
"The follow-up investigation will be carried out according to what you said. It will be roughly divided into two aspects, but the focus will be on exploring and finding the suspect."
"This is the most important line at the moment, and it must not be broken."
"Let's go, let's go down first."
"Let the technical department clean up the things here. Hopefully we can find other useful clues."
......
After determining the focus of reconnaissance.
Su Ming and Xu Changsheng walked slowly down the abandoned teaching building, while continuing to observe the traces of dust.
But there were no other extra discoveries.
Walk out of the abandoned teaching building.
I found that Shen Lin had already closed the body bag and was taking off rubber gloves, with a frown on his face and a slightly solemn expression.
It's obvious.
It was during the detailed autopsy that additional findings were made.
Xu Changsheng then quickly stepped forward and asked.
"Forensic Doctor Shen."
"Have you made any new discoveries?"
Shen Lin said slowly and solemnly while cleaning the autopsy tools.
"Just now when you two went upstairs."
"I lifted the clothes off the deceased's arms and found numerous small knife cuts. The direction of the cuts indicated that it was self-inflicted."
"Most of them have already healed and formed scabs, and only a few were caused not long ago, but they were definitely older than the fall."
"but."
"What makes me wonder is..."
"Even though there are so many wounds on my arms, there is no scar from a knife cut. This undoubtedly shows that..."
"The deceased's self-harming behavior only started during this period of time."
"But if depression is the cause of suicide, there should be a lot of normal things going on beforehand. At least the self-harming behavior should have occurred for at least a few months."
"It eventually progressed to self-harm. How could emotions progress so quickly?"
When Shen Lin finished speaking.
Su Ming suddenly thought of something and asked hurriedly.
"Forensic doctor Shen Lin."
"Did you collect the blood of the deceased?"
"Can you test it right away to see if there are any drug residues in it? Especially check if there are any traces of drugs!!!"
The words fell.
Xu Changsheng suddenly understood something and clapped his hands in realization.
"yes!"
"According to the autopsy results, the deceased progressed from self-harm to suicide in a very short period of time."
"According to the course of depression, this is obviously too fast!!!"
"It's very likely..."
"The deceased's mood changed so quickly because of the influence of certain drugs and medications. How could a 15-year-old middle school student get those drugs and medications?"
"If residues are detected in the blood, it would prove..."
"Someone is guiding the deceased to commit suicide!!!"
Su Ming, who was standing next to him, nodded in agreement.
It can be seen.
Being able to become the captain of the Huaihai Criminal Investigation Team, Xu Changsheng’s ability to solve cases must be very good.
I immediately judged from the self-inflicted wound on my arm...
This case.
There is always someone controlling everything in secret.
Shen Lin also understood what he meant, and immediately put on the rubber gloves he had just taken off, saying without hesitation.
"originally."
"I also feel that..."
"For a 15-year-old middle school student, there is definitely no rush to test for drugs and drug residues. We can just wait until we return to the technical department for a detailed test."
"But now it seems."
"This case is not as simple as it seems!!!"
"Give me some time."
"We are now beginning to test the deceased's blood."
After saying that.
Shen Lin opened the forensic tool box, took out the test tube containing the deceased's blood, shook it gently to mix it evenly, and then dropped it on the drug and medicine residue test strips respectively.
at the same time.
Su Ming and Xu Changsheng had already seen the vice-president, Zhang Heng, walking towards them with a middle-aged woman who was about 40 years old and had a sad face.
No need to think too much.
This woman is most likely the deceased's class teacher.
Xu Changsheng patted Su Ming's shoulder and took out his cell phone from his pocket.
"Xiao Ming, talk to them first."
"I'll notify the technical department to check the surveillance footage from last night near Shude Middle School to see if they can find any trace of the other person."
"This case..."
"It's getting worse now!!!"
......
It started as a simple suicide jump.
From the subsequent discovery of the wrist-cut wound to the current situation of malicious induction.
I have to say.
The case is indeed gradually developing in a more serious direction.
Find the truth.
It is also becoming more urgent.
Su Ming walked towards Vice Principal Zhang and the middle-aged woman who were coming towards him, stopped them in front of the cordon, and pointed to a chair not far away.
"It's not very convenient here. There are a lot of clues and matters to deal with."
"Let's go over there and talk."
Zhang Heng nodded quickly, took the middle-aged woman to a chair not far away and sat down, introducing them with a tap of his fingers.
"Officer Su."
"This is Zhang Wan's homeroom teacher, Wang Limei. She has worked at Shude Middle School for nearly 20 years and has taught more than a dozen graduating classes."
"Whether it's teaching philosophy or teaching experience, both are outstanding. There are not many people in the whole school who are as dedicated and experienced as Teacher Wang."
As Zhang Heng finished speaking.
Su Ming had already frowned slightly, and keenly discovered a hint of problem from her words. He looked at Wang Limei and asked.
"Teacher Wang."
"Before asking Zhang Wan about something, I want to ask you something else first..."
"Normally."
"There are only a few months left before the high school entrance exam. Even if the homeroom teacher of the graduating class does not have classes that day, he or she will go to the class during the morning reading time every day to check on the general situation."
"As a graduating class teacher for more than ten years, you should have this habit as well."
"so."
"During the morning reading period, until the end of the two classes in the morning, did you notice that Zhang Wan was not at her seat?"
