Opioids.
It is a powerful sedative and analgesic commonly used in clinical practice and has a certain degree of addictiveness.
The most famous ones are: morphine, pethidine, fentanyl, etc.
But no matter which one it is.
These are all drugs that are strictly controlled by the state and pharmacies are not allowed to sell them at all.
Only patients with advanced cancer can purchase the drug at large public hospitals with a doctor's prescription.
......
Now.
Since residual traces of drugs and opioids have been detected in the blood of the deceased.
This undoubtedly further confirmed Su Ming's inference.
Opioids have sedative and analgesic effects after taking them, but their side effects are extreme drowsiness, confusion, and addiction.
That explains it.
Why in the past ten days, Zhang Wan, who never slept in class before, became extremely sleepy for unknown reasons and even brought a pillow with her.
as well as.
The increasingly withdrawn and quiet personality is actually related to the sedative effect of the drug! ! !
Junior high school students absolutely cannot buy such drugs.
No doctor would dare to prescribe controlled drugs such as morphine and pethidine to middle school students.
Therefore, in this case of falling from a building.
There is definitely a suspect lurking behind the scenes, who is always controlling and directing this case! ! !
If we make a further bold inference...
Opioids have a strong analgesic effect, so it is very likely that the deceased injured his arm himself.
The effect of the drug renders the body's self-protection ability ineffective, causing the patient to not feel obvious pain or discomfort.
In this case.
The suspect took advantage of the situation and further controlled the victim's mind with drugs.
Gradually, the deceased is taught that suicide does not hurt, and that after death he will turn into a blue whale and gain freedom, etc.
Words with obvious hints of death! ! !
As for what drugs the suspect used, it also needs to be found out as soon as possible.
But the most important thing right now is...
Find the second key person in this case, Huang Yan, as soon as possible.
Judging from the way Huang Yan wiped away the footprints.
She probably doesn't plan to commit suicide immediately, so there's still a chance to save her!
......
After sorting out my thoughts.
Su Ming walked towards Xu Changsheng who was communicating with the technical department without hesitation.
exactly.
Xu Changsheng had just put down the phone, and when he saw Su Ming coming over, he frowned and complained.
“Damn it!”
"This lame suspect is a little hard to find. I just asked the Criminal Investigation Technology Department to remotely access the cameras at Shude Middle School."
"We immediately checked the surveillance cameras inside Shude Middle School and at several entrances and exits, but we didn't find any suspicious lame person!!!"
"Then."
"I also asked the security guard and confirmed that no one entered or left the campus at midnight last night."
"That shouldn't be the case!"
"With my limp and limited mobility, where else can I go except through the school entrance? I can't climb over the wall..."
Before Xu Changsheng could finish speaking.
Su Ming interrupted him and explained with some emotion.
"Brother Sheng."
"It's normal that you didn't find it!"
"I just talked to the deceased's two-year homeroom teacher and the vice-principal, and I have roughly confirmed the identity of the suspect!"
"The suspect who walked with the deceased on the rooftop for the last time and cut the deceased's radial artery should be the deceased's only friend of the same age. Her name is Huang Yan!"
"During the first and second year of junior high school, Huang Yan and the deceased were in the same class and established a deep friendship."
"But it was almost the end of the second semester of the second year of junior high school."
"Huang Yan was involved in a car accident, which resulted in a comminuted fracture of her left leg. Despite all efforts to save her, she was still left disabled and has been lame ever since."
"at the same time."
"Since Shude Middle School adopts a military-style boarding school management model, the lame Huang Yan is not suitable to continue studying here, and was advised to drop out during the summer vacation of the second year of junior high school."
"From being able-bodied to being disabled and lame, Huang Yan certainly had the soil to breed suicidal thoughts."
"Since you have studied here for two years, you must be very familiar with the situation on campus."
"So it's natural that the surveillance cameras didn't find Huang Yan."
"If I'm not mistaken..."
"Although Shude Middle School adopts military-style management, there are definitely places where the railings or walls have been damaged, allowing those students to sneak in and out of the campus."
"And Huang Yan entered and exited Shude Middle School through this gap."
"so."
"As long as we find this small path that only students know about, and then retrieve the surveillance footage of nearby roads, we should be able to find Huang Yan's whereabouts."
Hear this.
Xu Changsheng immediately patted his thigh and praised with surprise.
"Sure, Xiao Ming."
"The clue you found is very important. Once we identify the suspect who witnessed the case, the difficulty of finding and arresting him will be greatly reduced."
"I will ask Principal Qu to arrest a thug from the school and ask him about it."
"If you ask the bad guys in the school, I think they will know the secret ways to escape from school."
Su Ming first nodded in agreement.
Then his expression became serious again and he continued quite seriously.
"Brother Sheng."
"In addition to this information, I have another extremely important inference..."
"This case is most likely not a suicide by group or depression, but a premeditated homicide!!!"
"Huang Yan is not the murderer, nor is she an accomplice. On the contrary, she is also the target of the real murderer!"
"In this case, there is a third person, the real murderer, who has always been lurking in the dark and controlling everything!!!"
This conclusion.
Xu Changsheng was stunned for a moment, and then his expression became serious. He raised his head and gestured.
"Go on, Xiao Ming."
"Tell me how you inferred that there was a hidden murderer."
Su Ming didn't need to organize his thoughts at all and immediately explained.
"First point."
"When I asked the deceased's class teacher just now, I unexpectedly learned that in the past fifteen days, the deceased was particularly fond of and concerned about blue whales."
"In the letter from the deceased, he also mentioned that he wanted to become a blue whale after his death."
"as well as."
"The first suspect in this case, Huang Yan, also mentioned this to her former class teacher a month ago..."
"Can a person turn into a blue whale after death?"
"I seriously doubt that the freedom represented by the so-called blue whale is simply a concept that has been forcibly instilled in people in a short period of time."
"Second point."
"The earliest self-inflicted wound on the victim's arm has not yet become a complete scar."
"This shows that the time it took for the deceased to commit such extreme acts, from self-harm to jumping off a building to commit suicide, could have been less than 15 days."
"That's too short a time for depression to progress so quickly."
"Third point."
“That’s also the most important point.”
"Forensic doctor Shen Lin has detected residual drugs and medicines in the deceased's blood."
"Although the type of drug has not yet been determined, it has been determined to be an opioid for sedation and pain relief!"
"These two things are controlled items that junior high school students can't touch!!!"
"With all the evidence above, I have reason to believe it."
"There is definitely a hidden mastermind!!!"
As Su Ming finished his inference.
Xu Changsheng's face was filled with shock and confusion. How talented did he have to be to be able to unravel all these details and come up with a conclusion...
Such a shocking conclusion! ! !
Xu Changsheng was very sure that if he had gone to the deceased's class teacher to inquire about the case.
It is highly likely that he would not be able to obtain such a hidden clue like Su Ming did.
But Xu Changsheng had to admit...
Su Ming was not making random inferences. Instead, he grasped all the details and evidence to the extreme and guessed the key result.
Take a deep breath.
Xu Changsheng suppressed his inner shock and nodded vigorously in reply.
"Xiao Ming, your inference is very important."
"We must take this falling case seriously."
"Subsequent reasoning must also take into account this suspect whose whereabouts are unknown."
"but."
"The most critical interim goal now is..."
"Find Huang Yan!!!"
