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

Opioids.

It is a powerful sedative and analgesic commonly used in clinical practice and has a certain degree of addiction.

Some of the most famous ones are: morphine, pethidine, fentanyl, etc.

But no matter what.

They are all drugs strictly controlled by the state, and pharmacies are not allowed to sell them at all.

Only patients with terminal cancer can purchase it at public hospitals with a doctor's prescription.

......

just now.

Since traces of drugs and opioids have been detected in the blood of the deceased.

This undoubtedly further confirmed Su Ming's inference.

Opioids have a sedative and analgesic effect after being taken, but the side effects are extreme drowsiness, confusion and addiction.

That also explains it.

Why had Zhang Wan, who hadn't slept in class before, become extra sleepy in the past ten days or so, and even brought a pillow?

as well as.

The increasingly withdrawn and quiet personality is actually related to the sedative effect of the drug! ! !

Junior high school students will never be able to buy such drugs.

No doctor would dare to prescribe controlled drugs such as morphine and pethidine to middle school students.

So in this case of falling from a building.

There is definitely a suspect lurking behind the scenes, who is always controlling and guiding this case! ! !

If we make further bold inferences...

Opioids have extremely strong analgesic effects, so it is most likely that the deceased was self-harming his arm.

Due to the effect of the drug, the body's self-protection ability failed, so that he did not feel obvious pain and discomfort.

In this situation.

The suspect took advantage of the situation and further used drugs to control his consciousness.

Gradually instill in the deceased that suicide will not hurt, that after death he will turn into a blue whale and gain freedom, etc.

Words that clearly imply death! ! !

As for what drugs the suspect used, it needs to be found out as soon as possible.

But the most important thing right now is...

Find the second key figure in this case—Huang Yan—as soon as possible.

Judging from Huang Yan's actions of wiping away the footprints.

She probably had no immediate plans to commit suicide, and there was still a chance to save her!

......

After clearing your mind.

Su Ming walked towards Xu Changsheng who was in the communication technology department without hesitation.

exactly.

Xu Changsheng had just put down the phone and frowned and complained when he saw Su Ming approaching.

"Damn it!"

"This lame criminal suspect is a bit difficult to find. I just asked the Criminal Investigation Technology Department to remotely access the camera of Shude Middle School."

"I immediately checked the interior of Shude Middle School and the surveillance at several entrances and exits, but no suspicious lame person was found at all!!!"

"Then."

"I also asked the security guard to confirm that no one entered or left the campus at midnight last night."

"It stands to reason that it shouldn't be!"

"With my lameness and limited mobility, I can't go anywhere without using the school entrance and exit. It is impossible to climb over the wall..."

Before Xu Changsheng could finish speaking.

Su Ming interrupted his words and explained with some emotion.

"Brother Sheng."

"It's normal that I didn't find it!"

"I just talked with the deceased's two head teachers and the vice principal, and now I can roughly confirm the identity of the suspect!"

"The suspect who walked with the deceased on the rooftop for the last time and slit the radial artery of the deceased should be the deceased's only friend of the same age, and his name is Huang Yan!"

"During the first and second grade of junior high school, Huang Yan and the deceased were in the same class and established a profound friendship."

"But it's almost the end of the second semester of the second grade of junior high school."

"Huang Yan was accidentally involved in a car accident, resulting in a comminuted fracture of her left leg. After all-out treatment, she still became disabled and has been lame ever since."

"at the same time."

"Since Shude Middle School adopts a boarding-style military management model, Huang Yan, who is lame, is not suitable to continue studying here. She was persuaded to quit during the summer vacation of her second year of junior high school."

"From being able-bodied to being disabled and lame, there is indeed a breeding ground for suicidal thoughts in Huang Yan."

"Since I have studied here for two years, I must be very familiar with the situation on campus."

"So the reason why those surveillance eyes didn't find Huang Yan is naturally extremely normal."

"If I'm not wrong..."

"Although Shude Middle School adopts military training-style management, there are definitely areas where the railings or walls have been damaged to allow those students to sneak in and out of the campus."

"It is through this gap that Huang Yan enters and exits Shude Middle School."

"so."

"As long as we find this trail that only students know about, and then call in the surveillance of nearby roads, we should be able to discover Huang Yan's whereabouts."

heard here.

Xu Changsheng immediately patted his thigh and praised in surprise.

"Okay, Xiao Ming."

"The clue you dug up is very important. As long as the identity of the suspect who witnessed the case is confirmed, the difficulty of finding and arresting will be greatly reduced."

"I'm going to ask Principal Qu to arrest a school gangster and come here to question him."

"The best way to sneak out of school is by asking these bad gangsters in the school."

Su Ming nodded in agreement at first.

Then his expression became solemn again and he continued quite seriously.

"Brother Sheng."

"In addition to this information, I also have an extremely important inference..."

"This case is probably not a gang suicide, depression suicide, etc., but a premeditated murder!!!"

"Huang Yan is not the murderer, nor is she an accomplice. Instead, she is also the target of the real murderer!"

"In this case, there is a third person, the real murderer, who is always hiding in the dark to control and induce everything!!!"

This conclusion.

Xu Changsheng was stunned for a moment, and then his expression became solemn, and he raised his head to signal.

"Go on, Xiao Ming."

"Tell me where you deduce that there is a hidden murderer."

Su Ming didn't need to organize his thoughts at all and immediately explained aloud.

"The first point."

"When I just asked the deceased's class teacher, I unexpectedly learned that in the past fifteen days, the deceased had been particularly fond of and paid attention to blue whales."

"In the letter from the deceased, he also mentioned that he wanted to become a blue whale after death."

"as well as."

"The first suspect in this case, Huang Yan, also mentioned it to her former class teacher a month ago..."

"Can a person turn into a blue whale after death?"

"I seriously doubt that the so-called freedom represented by the blue whale is completely a concept that was forcibly instilled in a short period of time."

"Second point."

"The earliest self-inflicted wounds on the deceased's arms have not yet turned into complete scars."

"This shows that the deceased's extreme behavior from self-mutilation to falling from a building to commit suicide took a rough estimate of less than fifteen days."

"This is too short a period of time for depression to progress so quickly."

"The third point."

"Also the most important point."

"Forensic doctor Shen Lin has detected residual drugs and drugs in the blood of the deceased."

"Although the type of drug has not yet been determined, the drug has been identified as a sedative and analgesic opioid!"

"These two things are controlled items that junior high school students have no access to at all!!!"

"The above evidence gives me reason to believe it."

"There is definitely a hidden mastermind!!!"

As Su Ming finished speaking his inference.

Xu Changsheng's face was full of shock and confusion. How talented is it to be able to peel away the cocoons from such details and come up with a...

Such a shocking conclusion! ! !

Xu Changsheng was very sure that if he had just gone to the deceased's class teacher to inquire about the case.

There is a high probability that he would not be able to draw such hidden and deep clues like Su Ming.

But Xu Changsheng had to admit...

Su Ming was not reasoning randomly. Instead, he grasped all the details and evidence to the extreme and guessed the key results.

Take a deep breath.

Xu Changsheng suppressed the shock in his heart, nodded vigorously and replied.

"Xiao Ming, your inference is very important."

"We must take this falling case seriously."

"Follow-up reasoning must also consider this criminal suspect who is unknown where he is hiding."

"but."

"The most critical phased goal now is..."

"Find Huang Yan!!!"
