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

Opioids.

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

Among them, the most famous ones are: morphine, demerol, fentanyl and so on.

But either way.

All of them belong to the strict control of the state, and pharmacies are not allowed to sell them at all.

Only patients with advanced cancer can buy at large public hospitals with a doctor's prescription.

......

Right now.

Since the blood of the deceased has been detected, residual traces of drugs and opioids have been detected.

It is undoubtedly a further confirmation of Su Ming's inference.

Opioids have a calming and pain-relieving effect after taking them, while the side effects are that people are extremely lethargic, confused and addictive.

That explains that.

Why in the past ten days, Zhang Wan, who had not slept in class before, inexplicably became extremely sleepy, and specially brought pillows.

And.

The increasingly withdrawn and quiet personality is actually related to the sedative effect of drugs!!

And junior high school students will definitely not be able to buy such drugs.

Not to mention that no doctor would dare to prescribe controlled drugs such as morphine and demeraldine to middle school students.

Hence in this case of the fall.

There are definitely suspects lurking behind the scenes, always controlling and guiding this case!!

If further bold extrapolation ....

Opioids have a strong pain-relieving effect, so it is very likely that the deceased died when the arm self-harmed.

Due to the action of the drug, the body's ability to protect itself is ineffective, so that it does not feel obvious pain and discomfort.

In this case.

The suspect took advantage of the void to further use drugs for consciousness control.

Gradually instilling that the deceased will not be painful to commit suicide, and after death, it will become a blue whale and be free, and so on.

Words with obvious hints of death!!

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

But the most important thing at the moment is....

Find the second key person in this case - Huang Yan as soon as possible.

Judging from Huang Yan's action of wiping off her footprints.

She should have no intention of committing suicide immediately, and there is 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.

Just right.

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

"Damn it!"

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

"The first time I checked the inside of Shude Middle School, as well as the monitoring of several entrances and exits, I didn't find any lame suspicious figures!!

"Then."

"I also asked the security guard to make sure that no one came in or out of the campus in the middle of the night last night."

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

"In the case of lame mobility and mobility difficulties, where can you go without going to the entrance and exit of the school, it is always impossible to climb over the wall..."

Before Xu Changsheng finished speaking.

Su Ming interrupted his words and explained with some emotion.

"Brother Sheng."

"It's normal if you don't find it!"

"I have just talked to the deceased's two-term class teacher and vice principal, and I can now roughly confirm the identity of the suspect!"

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

"In the first and second years of junior high school, Huang Yan and the deceased established a deep friendship in the same class."

"But when the second semester of junior high school is almost over."

"Huang Yan accidentally suffered a car accident, resulting in a crushing fracture of her left leg, but after full treatment, she was still disabled and has been lame ever since."

"At the same time."

"Since Shude Middle School adopts a militarized management model of boarding system, the lame Huang Yan is not suitable to continue her studies here, and she was dissuaded from the summer vacation of junior high school."

"From being physically sound to being disabled and lame, Huang Yan does have soil for suicidal thoughts."

"Since I have studied here for two years, I must be very clear about the situation in school."

"Therefore, the reason why those monitoring heavenly eyes did not find Huang Yan is naturally an extremely normal situation."

"If I'm not mistaken..."

"Although Shude Middle School adopts military training management, there are definitely places where the railings or fences are damaged for those students to sneak in and out of the campus."

"And Huang Yan is entering and leaving Shude Middle School through this gap path."

"So."

"As long as you find this trail that only students know, and then call the monitoring of nearby roads, you should be able to find out Huang Yan's whereabouts."

Hear it here.

Xu Changsheng immediately slapped his thigh and praised it in surprise.

"Yes, Xiaoming."

"This clue you dig up is very important, as long as the identity of the suspect who witnessed the case is determined, the difficulty of finding and arresting will be much reduced."

"I'll let Principal Qu grab a school gangster and ask me now."

"This kind of secret way to escape school, asking these bad gangsters in the school is estimated to be the clearest."

Su Ming nodded approvingly.

Immediately, his expression became solemn again, and he continued quite seriously.

"Brother Sheng."

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

"This case is most likely not a partner suicide, depression suicide and other types, but a premeditated homicide !!."

"Huang Yan is not a murderer, nor an accomplice to assist, but also the target of the real murderer!"

"In this case, there is a third person, the real murderer, who has been lurking in the shadows to control and induce everything!!."

This conclusion.

Ling Xu Changsheng was stunned, and then his expression became solemn, and he raised his head and signaled.

"Go on, Xiaoming."

"Tell me where you deduced the existence of a hidden murderer."

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

"First point."

"When I just asked the head teacher of the deceased, I unexpectedly learned that in the past fifteen days, the deceased particularly liked and paid attention to blue whales."

"In the letter of the deceased, it is also mentioned that he wants to become a blue whale after death."

"And."

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

"I seriously suspect that the freedom represented by this so-called blue whale is completely an idea that has been forcibly indoctrinated in the short term."

"Second point."

"The earliest self-mutilation wound on the deceased's arm has not yet become a complete scar."

"This shows that the time for such an extreme behavior of the deceased from self-harm to suicide from falling into a building may be less than fifteen days."

"It's too short a time for depression to progress so fast."

"Third point."

"It's also the most important point."

"Shen Lin's forensic doctor has detected residual drugs and drugs from the blood of the deceased."

"Although the type of drug has not yet been determined, the drug can already be identified as an opioid for analgesia!"

"These two things are controlled items that junior high school students can't touch!!

"With so much evidence above, I have reason to believe."

"There is definitely a hidden behind-the-scenes !!"

As Su Ming finished his inference.

Xu Changsheng's face was already full of shock and puzzlement, how talented it must be to extract from this kind of details and come up with one...

What a shocking conclusion!!

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

Most likely, it is impossible to draw such hidden and deep clues like Su Ming.

But Xu Changsheng had to admit it...

Su Ming was not reasoning indiscriminately, but grabbed all the details and evidence to the extreme and guessed the key result.

Take a deep breath.

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

"Xiao Ming, this inference of yours is very important."

"We must pay thorough attention to this case of falling."

"Subsequent reasoning should also consider this suspect who does not know where to hide."

"But."

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

Find Huang Yan!!
