sleep with wolves

Chapter 144

"The deceased is He Mou, 22 years old this year, a senior undergraduate student at Ancheng Medical University."

As Lu Yuan said, he pulled out a photo of the deceased. In the photo, He Mou's eyes were wide open, his face was blue, and his expression was frightened. It looked like he was frightened to death.

"You have also seen that the last appearance of him was like seeing something frightening. However, according to the forensic examination, his death was indeed strange. After an autopsy, it was found that he died because of cyanide."

After these words fell, everyone in the conference room sighed.

Cyanide, they know more or less when they are policemen.

Seeing Shen Yu frowned slightly, Gu Yan explained in a low voice:
"Cyanide is a colorless gas, highly toxic, it is very difficult to revive the poisoned person, they can stop breathing in just a few minutes, and four adults can't smell it at all, because the corresponding gene is missing , only the colorless crystals of potassium cyanide and sodium cyanide, in humid air, hydrolyze to produce hydrocyanic acid and have a bitter almond flavor."

A few seconds after ingestion of cyanide, irritability, fear, cyanosis, general convulsions, and immediate respiratory arrest appear.

Therefore, it is also highly consistent with the expression of the deceased when he died.

Shen Yu listened to her rigorous science popularization, and finally came to a conclusion:
Very poisonous, hard to save.

"So now it seems that it is determined that he killed it."

"That being said, how did he get poisoned?" Someone wondered.

Indeed, what was the method of poisoning? If you find out the method of poisoning and check who had contact with him at the time of death, the real culprit can be determined to a large extent.

Lu Yuan called up a picture on the big screen, which was a white medical sheet.

Gu Yan looked at the white sheet, frowning slightly.

If it's what she thinks now, then it overturns her previous guess.

Lu Yuan said at this time:
"White bed sheet, this is the thing that covered the body of the deceased at that time. Frankly speaking, to play this game, the player needs to lie on the bed and cover this sheet. compound."

The cyanide was changed from a gaseous state to a liquid state and dissolved in a white sheet.

"So, when the deceased saw a ghost outside the door, he would run to hide in the room in fright, lie on the bed covered with a sheet, and breathe heavily. At this time, a large amount of cyanide was inhaled into the body."

A police officer snapped his fingers and said.

Gu Yan has been silent all the time, she also has a file of this case in her hand, and she is looking through it seriously at the moment.

"At that time, the person who formed a group with He was a girl named Xu Xiaoya. She is also the biggest suspect at present. We went to her school to investigate and found that she has a bad personality and gets along with teachers and classmates extremely unhappy."

Lu Yuan continued to explain.

Gu Yan raised his eyebrows slightly, this girl was the one who kept looking down on him in the secret room before.

She has hypermemory, so she can remember everything very clearly.

Gu Yan didn't know what to think of, his eyes flickered, and his tone was calm and composed:

"Although they are a group, she also has the opportunity to commit the crime, but what is the motive? What is the motive?"

The poisonous white cloth sheet can be brought in to change the bag on the spot. This kind of thing is easy to hide and will not be checked.
