After simulating crimes 100,000 times, I became an ace detective

Suspect. ♦♦ ♦♦

Or the word witness.

Perhaps neither of them can accurately describe the second special person in this case.

It can be confirmed.

In the short time after falling from the building, she cut the radial artery of the deceased and caused secondary injury.

However.

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

She is more like...

The only friend who accompanied the deceased on the last journey.

But no matter what her identity is.

Anyone who wants to thoroughly understand this case must find this person.

......

At this moment.

Under Su Ming's reminder.

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

This suspect who witnessed the deceased falling from the building.

It is also very likely that he committed suicide, otherwise why only wiped off the footprints?

At the same time.

Xu Changsheng also considered another point.

Even if these two children are ignored and bullied by the people around them, it is not so easy to make the decision to commit suicide.

Not to mention that both of them made this decision.

Does this mean...

Just as Su Ming guessed, there is actually a big hand behind the fall, inducing and controlling everything.

Without thinking too long.

Xu Changsheng immediately walked up a few steps and called at the door of the rooftop.

"Xiao Ming."

"The follow-up investigation will be carried out as you said, roughly divided into two aspects, but the focus should be on exploring and finding the suspect."

"This is the most important line at present, and it must not be broken."

"Let's go, go down first."

"Let the technical department clean up the things here, and hope to find other useful clues."

......

After determining the focus of the investigation target.

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

But there were no other extra discoveries.

Walking out of the abandoned teaching building.

Found that Shen Lin had pulled up the body bag and was taking off rubber gloves, frowning and slightly solemn.

Obviously.

This was during the detailed autopsy, there were other additional discoveries.

Xu Changsheng then stepped forward and asked hurriedly.

"Forensic Doctor Shen."

"Do you have any new discoveries?"

Shen Lin said solemnly while cleaning the autopsy tools.

"Just when you two went up."

"I lifted the clothes on the deceased's arm and found a large number of small knife cuts. According to the direction of the cuts, it can be judged as self-harm."

"Most of them have healed and scabbed. Only a few were caused not long ago, but they must be earlier than the time of falling from the building."

"But."

"What makes me very strange is..."

"Even though there are so many wounds on the arm, there is no knife scar, which undoubtedly shows..."

"The deceased's self-harm behavior only started during this period of time."

"But if depression caused suicide, there should be a lot of normal in the early stage, at least the self-harm behavior should have appeared for at least a few months."

"It gradually developed into self-harm in the end, why can the emotional progress be so fast."

When Shen Lin finished speaking.

Su Ming suddenly thought of something and asked hurriedly.

"Forensic doctor Shen Lin."

"Have you collected the deceased's blood?"

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

After the words fell.

Xu Changsheng suddenly understood something and clapped his hands in realization.

"Yes!"

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

"According to the course of depression, this is obviously too fast!!!"

"It is very likely..."

"The influence of certain drugs and drugs caused the deceased's mood to change so quickly, and as a 15-year-old middle school student, how could he get those drugs and drugs?"

"If residues are detected in the blood, it can prove..."

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

Su Ming, who was standing next to him, nodded in agreement.

It can be seen.

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

Immediately judged from the self-mutilation wound on his arm...

This case.

There is always someone secretly controlling everything.

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

"Originally."

"I thought..."

"A middle school student who is only 15 years old must not be in a hurry to test drugs and drug residues. Just wait until we return to the technical department for detailed testing."

"But now it seems."

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

"Give me some time."

"Start testing the blood of the deceased now."

After saying that.

Shen Lin opened the forensic tool box, took out the test tube containing the deceased's blood, shook it gently, and dripped 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 in her forties with 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 mobile phone from his pocket.

"Xiao Ming, you talk to them first."

"I'll notify the people in the technical department to turn on the Sky Eye surveillance near Shude Middle School last night to see if there is any trace of another person."

"This case..."

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

......

From the simple suicide fall at the beginning.

To the subsequent discovery of the wrist cut wound, to the current existence of malicious induction.

I have to say.

The case is indeed gradually developing in a more serious style.

Finding the truth.

It is also more urgent.

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

"It's not very convenient here. We have to deal with a lot of clues and affairs."

"Let's go over there and talk."

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

"Officer Su."

"This is Zhang Wan's class teacher - Wang Limei. She has been working in our Shude Middle School for nearly 20 years and has taught more than a dozen graduating classes."

"Both her teaching philosophy and her class teaching experience are outstanding. There are not many people in the whole school who can be as conscientious and experienced as Teacher Wang."

As Zhang Heng finished speaking.

Su Ming had already frowned slightly, keenly discovered a hint of problem from her words, and looked at Wang Limei and asked aloud.

"Teacher Wang."

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

"Normally."

"There are only a few months left before the high school entrance exam. Even if the head teacher of the graduating class has no classes that day, he will go to the class to check the general situation during the morning reading time every day."

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

"So."

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