After 100,000 simulated crimes, I became an ace detective

Suspect.

Or the word witness.

Perhaps it is impossible to accurately describe the second person in this case, which is quite special.

Can be determined.

Within a short time of the fall, she cut the radial artery of the deceased and caused secondary injuries.

But.

Follow the warm picture on the dining cloth on the roof, and the letter left by the deceased.

She's more like....

The only friend who accompanied the deceased on that last leg of the road.

But no matter what kind of identity.

But anyone who wants to completely clarify this case must definitely find this person.

......

Now.

Under Su Ming's reminder.

Xu Changsheng reacted immediately, indeed according to the current details.

The suspect who witnessed the deceased's fall from the building.

There is also a great possibility of suicide, otherwise why just wipe off the footprints?

Meantime.

Xu Changsheng also considered another point.

Even if both children are neglected and bullied by those around them, the decision to commit suicide is not so easy.

Not to mention that both people made this decision.

Does this illustrate....

As Su Ming guessed, in fact, there was a big hand behind this fall, which was inducing and manipulating all this.

Didn't think for too long.

Xu Changsheng immediately took a few steps up and greeted at the door of the rooftop.

"Xiao Ming."

"The follow-up investigation is roughly divided into two aspects according to what you said, but the focus should be on probing and finding suspects."

"This is the most important line at the moment, but it must not be broken."

"Let's go, let's go down first."

"Those things here, let the technical department clean up when the time comes, hoping to find other useful clues."

......

After determining the focus of reconnaissance targets.

Su Ming and Xu Changsheng walked slowly down the abandoned teaching building, not forgetting to continue to observe the dust traces during the period.

But nothing else was found.

Get out of an abandoned school building.

It was found that Shen Lin had pulled the body bag up and was taking off her rubber gloves, her brows furrowed and her expression slightly solemn.

It's clear.

This was at the time of a detailed autopsy that there were other additional findings.

Xu Changsheng immediately stepped forward quickly and quickly asked.

"Forensic Shen."

"Do you have any new discoveries?"

Shen Lin said in a rather solemn slow voice while cleaning up the autopsy tools.

"Just when you two went up."

"I lifted the clothes off the deceased's arm and found a large number of small knife wounds, which could be judged to be self-harm based on the direction of the knife cut."

"Most of them have healed and scabbed, and only a few have just caused them, but they certainly predate the fall."

"Yet."

"What makes me very strange is

..." "Even if there are so many wounds on the arm, none of the scars of the knife cut exist, which undoubtedly shows..." "

The deceased's self-harm behavior only began during this time."

"But if depression leads to suicide, there should be a lot of normality in the early stage, at least self-harm behavior should have been around for at least a few months."

"Finally, it gradually develops to self-harm, why can emotions progress so quickly."

When Shen Lin finished saying this.

Su Ming suddenly thought of something, and immediately quickly asked.

"Shen Lin forensics."

"Did you collect the blood of the deceased?"

"Can you immediately detect whether there is any drug residue in it?" In particular, check for traces of the presence of drugs!! The

voice fell.

Xu Changsheng immediately understood something, and slapped his palm to wake up.

"Yes!"

"According to the results of the autopsy, the deceased progressed from self-harm to suicidal behavior in a very short period of time."

"According to the course of depression, it was obviously a little too fast!!"

"

There were certain drugs and the effects of drugs that caused the deceased's mood to change so quickly, and as a fifteen-year-old middle school student, how do you get those drugs and drugs?"

"If residue is detected in the blood, it proves..." "

Someone is leading the deceased to commit suicide!!

Su Ming, who was standing next to him, nodded approvingly.

It can be seen.

Being able to become the captain of Huaihai criminal investigation, Xu Changsheng's ability to solve cases is definitely not bad.

Immediately judging from the self-mutilation wound on the arm....

This case.

There is always someone in control of everything in secret.

Shen Lin also understood what it meant, and immediately put the rubber gloves she had just taken off back on, and said without hesitation.

"Originally."

"I still think..." "

A fifteen-year-old middle school student must not be in a hurry to test drugs and drug residues, just wait until he returns to the technical department for detailed testing."

"But now it seems."

"This case is not as simple as it seems!!"

"Give me a little time."

"Start testing the blood of the deceased now."

After speaking.

Shen Lin opened the forensic toolbox, took out the test tube containing the blood of the deceased, gently shook it evenly, and then dripped it on the drug and drug residue test strips respectively.

Meanwhile.

Su Ming and Xu Changsheng had already seen Vice Principal, Zhang Heng, walking towards here with a middle-aged woman about forty years old with a sad face.

No need to think about it.

This woman is most likely the head teacher of the deceased.

Xu Changsheng patted Su Ming's shoulder, took out his mobile phone from his pocket and signaled.

"Xiao Ming, you talk to them first."

"I went to inform those people in the technical department and called up the Sky Eye monitor near Shude Middle School last night to see if I could find the trace of another person."

"This case..."

"It's getting more and more serious now!!"

......

From the beginning, a simple suicide fall.

To the subsequent discovery of the wrist cut wound, until now there is a malicious induced situation.

It has to be said.

Cases are indeed gradually moving towards an increasingly significant pattern.

Find the truth.

It is also becoming more urgent.

Su Ming walked towards the oncoming Vice Principal Zhang and the middle-aged woman, stopped the two in front of the police cordon, and pointed to the chair road not far away.

"It's not very convenient here, and there are a lot of clues and affairs to deal with."

"Let's go over there and talk."

Zhang Heng nodded quickly, led the middle-aged woman to the chair not far away and sat down, and introduced with a tap of his finger.

"Officer Su."

"This is Zhang Wan's homeroom teacher, Wang Limei, who has been working in our Shude Middle School for nearly 20 years and has also led more than a dozen graduating classes."

"Whether it is the teaching concept or the experience of leading classes, it is quite outstanding, and there are not many people in the whole school, and there can be such a conscientious and experienced teacher Wang."

As Zhang Heng finished speaking.

Su Ming was already frowning slightly, keenly finding a trace of a problem from his words, and looked at Wang Limei and asked aloud.

"Teacher Wang."

"Before I ask Zhang Wan about something, I want to ask one other thing first..."

"At present, there are only a few months left before the middle school entrance examination, and even if the class teacher of the graduating class is not in class that day, he will go to the class every morning to see the general situation."

"As a graduating class teacher for more than ten years, you should also have this habit."

"So."

"During the morning reading period, until the end of the two morning classes, did you find that Zhang Wan was not in her seat?"
