Yuan Chen asked him, "What does it mean to be outstanding?"
"In the ordinary sense, he is a good student with excellent academic performance."
In fact, when he was a student, Wei Chen had always been a representative of top students, that is, what those meddling parents call "other people's children." During college, he even won a scholarship every year.
It's just that such a child was born into such a family.
Qian Cheng's words made Yuan Chen find it even more difficult to understand. Could a good student with both good character and academic performance have such an idle mentality?
............
Before closing the case, all the police officers involved in the case gathered together and once again came to the crime scene, Wei Chunlai's home.
"I said, after we go and confirm today, this case should be closed."
Hao Weida stretched out his hands and yawned widely.
"Yes."
Yuan Chen said against his will. He knew very well that this was his last chance. If nothing unexpected happened, after this trip, Wei Chunlai's case would be confirmed as suicide, and it would be useless to say anything at that time.
Since Wei Chunlai's case is still under investigation and a cordon has been set up outside the crime scene, Zhang Yan and her son have not returned home during this period, so the scene is still very well preserved.
Just like when Yuan Chen stepped out of the door that night, he was with Qin Mengke.
Everything in the bedroom was arranged neatly, except for the bedside table that had been moved to the wall. There was an overturned stool where the bedside table was originally placed. This could be distinguished from the marks on the floor tiles.
A picture like this seemed to appear in everyone’s eyes:
Wei Chunlai came to the bedroom, first moved the bedside table, then moved the stool, stepped on the stool and tied it to the chandelier with a rope, tied a knot, then put his head in, kicked the stool, OK, the suicide was successful.
A nearly perfect suicide, most people think so.
The rope on the chandelier is still hanging there. When it was created, the person who created it would never have thought that one day it would become a tool used to kill people.
Yuan Chen walked to the trash can. There was originally an injection in it, but it was taken away by Qin Mengke on the night of the incident. Now the rest of it is genuine garbage.
He opened the drawer in the bedroom, and there was a large amount of rock sugar inside. It was probably used to prevent overdose of insulin and to supplement sugar.
Since Wei Chunlai chose to commit suicide, why did he inject insulin before committing suicide? Perhaps, he suddenly had this idea?
This problem remains unexplained.
Yuan Chen still felt suspicious. The injection was in the trash can. Although it could not be proven that he injected it just before committing suicide, it might have been during the day, but his blood test report showed that he had overdosed on insulin.
Obviously, he had already taken precautions against this. If he noticed a drop in blood sugar, he would definitely eat rock sugar to relieve it. In this way, the blood test would not detect that his blood sugar was too low. But the fact is exactly the opposite. What is the explanation for this?
The telepathic image came back to his mind.
A pair of hands tied a knot in the rope on the chandelier.
Look at the rope and chandelier, they are no different from what I remember, even the style and shape are the same.
As for those hands...
Wait a minute, hand?
He tried his best to recall the details about those hands. Those hands were long and fair, and the palms were not wide. They were very different from Wei Chunlai's hands.
Wei Chunlai is a driver. He travels around all the time. His hands are rough and tanned, and his fingers are calloused. Moreover, his palms are relatively wide, so it should be easier to hold the steering wheel.
That was definitely not Wei Chunlai’s hand!
Then, someone else should have hung this rope on the chandelier, but the person who hanged himself was Wei Chunlai. If he hadn't tied the knot himself, then...
A terrible thought appeared in Yuan Chen's mind.
It was at that moment that he came up with an idea that seemed illogical and was therefore ignored by the police.
They have been trying to prove whether Wei Chunlai's death was suicide or homicide, but they have ignored the cause of Wei Chunlai's death.
Did he really hang himself?
This seems to be a taken-for-granted question. When the body was found, Wei Chunlai was hanging from the ceiling like a puppet. Anyone would associate his death with hanging.
It saves time, money, and effort, and according to legend, you can go to heaven. This is indeed the most popular suicide method for thousands of years.
Hanging = suicide, this is almost everyone's consensus.
But now, Yuan Chen had to start considering other possibilities.
Regarding this point, Qin Mengke has actually given a specific identification report. There is no doubt that the cause of his death was typical mechanical asphyxia.
But what if there is a drug that can cause similar death characteristics but cannot be detected in an autopsy?
Unfortunately, this drug still exists and is widely used in clinical medicine and execution of lethal injections.
Succinylcholine.
This is a drug that can relax muscles. It is often used for intraoperative anesthesia to maintain muscle relaxation. Once this drug is overdosed, it will cause the patient's body to become flaccid and unable to breathe. If he does not rely on equipment to maintain breathing, he will soon die.
Suffocated to death.
Moreover, it is a substance that exists in large amounts in the human body and can be quickly metabolized. Therefore, an autopsy cannot detect whether the content of succinylcholine in the body of the deceased exceeds the standard. The cause of death can only be inferred through evidence of drug use.
Wei Chunlai had used insulin before his death. If the injection contained a certain amount of succinylcholine, he would have been paralyzed by the drug. At this time, no matter how he was manipulated, he would not have the strength to resist, and would even lose consciousness.
In this way, there will naturally be no traces of struggle on the crime scene and the body.
The murderer only needs to tie the rope that Wei Chunlai had touched before to the chandelier, and hang Wei Chunlai up while Wei Chunlai was suffocating due to the drug, so that he can perfectly disguise his suicide.
If this conjecture is true, the murderer used the method of "suicide" to cleverly disguise the death characteristics left by succinylcholine. Since Wei Chunlai suffered from diabetes, he would frequently inject insulin, so the pinholes left on his body would not be
aware.
It can be said that this is almost a perfect crime.
