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

suspects.

Or the word witness.

Perhaps even this cannot accurately describe the rather special second person in this case.

can be determined.

In the short time after falling from the building, she slit the deceased's radial artery and caused secondary injury.

but.

Follow the warm picture on the rooftop tablecloth and the letter left by the deceased.

She's more like...

The only friend who accompanied the deceased on his final journey.

But no matter what the identity is.

If you want to thoroughly understand this case, you must find this person.

......

now.

Under 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 of committing suicide, otherwise why would the footprints be just wiped away?

Simultaneously.

Xu Changsheng also considered another point.

Even though both children were ignored and bullied by those around them, making the decision to commit suicide was not that easy.

Let alone two people making this decision.

Does this mean...

Just as Su Ming had guessed, there was actually a big hand behind this fall that was inducing and controlling everything.

Didn't think long.

Xu Changsheng immediately walked up a few steps and greeted at the door 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 should 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, go down first."

"Those things here will be sorted out by the technical department when the time comes. I hope they can find other useful clues."

......

After determining the focus of investigation targets.

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

But there were no other unnecessary discoveries.

Walk out of the abandoned teaching building.

She found that Shen Lin had already closed the body bag and was taking off her rubber gloves, her brows furrowed and her expression slightly solemn.

It is clear.

It was during a detailed autopsy that additional findings were made.

Xu Changsheng immediately stepped forward and asked quickly.

"Forensic Doctor Shen."

"Have you made any new discoveries?"

Shen Lin said slowly and solemnly while cleaning the autopsy tools.

"When you two went up just now."

"I lifted off the clothes on the deceased's arms and found a large number of small knife wounds. Based on the direction of the knife cuts, it can be judged as self-inflicted wounds."

"Most of them have healed scabs, and only a few have just formed, but they must have been earlier than the time of the fall."

"but."

"What makes me very strange is..."

"Even though there are so many wounds on the arm, there is not a single scar from a knife. This undoubtedly shows..."

"The deceased's self-mutilation behavior only started during this period."

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

"In the end, it gradually progressed to self-mutilation. Why can the mood progress so quickly?"

When Shen Lin finished speaking.

Su Ming suddenly thought of something and asked quickly.

"Forensic Doctor Shen Lin."

"Did you collect the blood of the deceased?"

"Can you test it immediately to see if there are any drug residues in it? Especially to check if there are any traces of drugs!!!"

The voice fell.

Xu Changsheng understood something immediately, clapped his palms and said in realization.

"Yup!"

"According to the results of the autopsy, 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!!!”

"Very likely......"

"There were certain drugs and drugs that caused the deceased's mood to change so quickly. As a fifteen-year-old middle school student, how could he obtain those drugs and drugs?"

"If residue is detected in the blood, that would prove..."

"Someone is leading the deceased to commit suicide!!!"

Su Ming, who was standing nearby, nodded in agreement.

As can be seen.

To become the captain of Huaihai Criminal Investigation, Xu Changsheng's ability to solve crimes is definitely not bad.

I could immediately tell from the self-inflicted wounds on my arms...

this case.

There is always someone secretly controlling everything.

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

"originally."

"I also think..."

"Middle school students who are only fifteen years old are definitely not in a hurry to test for drugs and drug residues. They can wait until they return to the technical department for detailed testing."

"But now it seems."

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

"give me some more time."

"Testing on the deceased's blood will begin now."

After speaking.

Shen Lin opened the forensic tool box, took out the test tubes containing the blood of the deceased, shook it gently and dropped it on the drug and drug residue test paper respectively.

at the same time.

Su Ming and Xu Changsheng had already seen the vice principal, Zhang Heng, walking towards here with a middle-aged woman about ten years old with a sad face.

No need to think.

This woman is most likely the deceased's class teacher.

Xu Changsheng patted Su Ming on the shoulder, took out his cell phone from his pocket and signaled.

"Xiao Ming, please talk to them first."

"I'm going to notify the people in the technical department to call up the Sky Eye surveillance near Shude Middle School last night to see if we can find any trace of another person."

"This case..."

“It’s getting more and more serious now!!!”

......

A simple suicide fall from the beginning.

From the cut wrist wound discovered later, to the present situation, the existence has been maliciously induced.

have to say.

The case is indeed gradually developing into more and more serious forms.

Find the truth.

It also became more and more urgent.

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

"It's not very convenient here. There are a lot of clues and things 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, and introduced her with a light finger.

"Officer Su."

"This is Zhang Wan's class teacher, Wang Limei. She has worked at Shude Middle School for nearly twenty years and has led more than a dozen graduating classes."

"Both the teaching philosophy and class leading experience 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 frowned slightly, keenly detecting a problem in his words, and looked at Wang Limei and asked.

"Teacher Wong."

"Before asking about classmate Zhang Wan, I want to ask something else first..."

"Normally."

"There are only a few months left before the high school entrance examination. Even if there is no class that day, the head teacher of the graduating class 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 also have this habit."

"so."

"During the morning reading period, from the first to the end of the two classes in the morning, did you notice that Zhang Wan was not in his seat?"
