Cop Universe

Chapter 49 Deciphering the Means of Assault
In front of everyone, He Jiahui walked to the table, picked up a piece of leftover butter puff pastry, and took a bite.

"Well, no wonder Feng Ji's dim sum is so famous, the taste is really good." He Jiahui said to himself.

"Jiahui, are you crazy? Don't die!" Qiu Junxuan shouted from the side.

"What are you afraid of? Hasn't the forensic evidence been tested? It's not poisonous." He Jiahui said with a smile.

"Then you can't eat either!"

This time it was Huang Qifa who spoke, and he also shouted loudly: "These are all evidence, don't you know? Are you so hungry that you even eat the evidence! This is destroying the evidence!"

Huang Qifa originally hoped that He Jiahui, the great master of crime solving, would take him to do a dungeon, but the dungeon was not finished, so he destroyed the evidence first. Isn't this adding to the chaos!
He Jiahui had a disapproving expression on his face. He pointed to his mouth and said, "Inspector Huang, look!"

"What am I looking at? To see you destroying the evidence? Or to see how delicious your food is? Also, quickly put down the evidence!" Huang Qifa roared angrily.

"That's right, you didn't ask me 'Is it really delicious', it's considered an improvement."

He Jiahui teased Huang Qifa, then put down half a piece of butter puff in his hand, spread his hands, shook them in front of Huang Qifa, and asked:

"Inspector Huang, look at my hand, how is it different from before?"

"What's the difference? You can grow a sixth finger?" Huang Qifa snorted coldly.

"Inspector Huang, didn't you see it? My right hand, which took the egg yolk cake just now, is now covered with oil, and my left hand, which didn't hold the egg yolk cake just now, is still very clean."

He Jiahui pointed to his mouth again, and continued: "Not only my hands, but my mouth was also stained with oil from eating butter puff pastry. Well, this Feng Ji's butter puff pastry tastes good, but the oil used many."

"Nonsense, how can you eat butter puff pastry without getting oily!" Huang Qifa still didn't understand what He Jiahui meant.

He Jiahui continued; "However, these companions of the deceased also ate Feng Ji's snacks, but they didn't get any oil stains on their hands."

"I wiped off the oil stains, can't I?" Huang Qifa replied.

"That's right, their hands and mouths are clean because they wiped them. Then the question arises, where are the paper towels they used to wipe their mouths and hands?" He Jiahui asked with a smile.

Huang Qifa glanced at the trash basket, there were only a few egg tart trays in it, and there were indeed no paper towels or anything like that.

"Those are garbage, they must have been cleaned up!" Huang Qifa said.

The owner of the bar next to him immediately said: "Sir, our service here is very good, I specifically ask the waiter to clean up the garbage in time when they see it, and don't wait until the garbage basket is full.

Especially when there are customers ordering fruit plates, it is necessary to clean up the garbage in time, otherwise the sweetness of the fruits will attract some small flying insects, which will affect hygiene and affect the appetite of customers. "

"What about the garbage collected from this table?" He Jiahui continued: "Now, these garbage are all evidence and must be found."

"Well..." The bar owner showed a embarrassed expression: "The garbage is piled up in the garbage bin at the back! But we have to clear so many bags of garbage a day, how do I know which bag of garbage belongs to this table? "

"It's easy, look for the garbage bag with the cream cake tray inside." He Jiahui pointed to the unfinished birthday cake on the table, and continued: "Apart from this table, is there anyone else celebrating their birthday today? No one else either Eat butter cake."

"I see, I'll send someone to look for it right away." The bar owner is still very cooperative with the police.

Forensic also said, "I'll go with them, lest they destroy the evidence!"

The brioche tray was the obvious feature, and it didn't take long for the forensics to find the bag of trash.

"It should be this bag. There is a tray of cream cake in it. The cream residue left on it is the same as the cake on the table." Fa Zheng said.

"Then there should be used wet wipes in the trash bag, right?" He Jiahui asked.

"Yes." Forensic nodded.

He Jiahui said, "Please test these wet tissues and see which one has a cyanide reaction."

The forensic work began immediately, and the results were soon available.

"We found residues of cyanide on three wet paper towels, one of which had been soaked with cyanide. There was a small amount of cyanide on the other two, which should have been placed in a garbage bag and covered with cyanide. The wet wipes were contaminated with chemicals." The forensic report reported the results.

Upon hearing this result, He Jiahui immediately showed a victorious smile: "As expected, that wet tissue soaked in cyanide is the real source of poison!
After eating the butter puff pastry, the deceased must have oil stains on his hands and mouth. He needed to wipe his hands and mouth with a wet tissue, and what he used was the poisoned wet tissue.

In this way, the dead man's hands and lips are stained with cyanide, and then he eats food with his hands, and the food will be stained with cyanide. He drinks beer with his mouth, and the beer will also be stained. Get cyanide on it.

And whether he eats or drinks beer, the cyanide will be eaten by him, which means that as long as he uses this poisonous tissue, he will definitely die! "

"So that's it! This is the murderer's method of killing!" Huang Qifa let out a sigh of relief. Although he still doesn't know who the murderer is, at least the source of the poison and the murderer's method of killing have been deciphered.

Then Huang Qifa asked, "How did you come up with wet wipes?"

"It's all thanks to Mr. Lin!" He Jiahui looked at Lin Zhijian and continued, "I was just thinking about how to get the dead man's hands covered in cyanide.

And just at this time, Mr. Lin proposed that he was willing to undergo a body search and inspection, and at that time stretched out his hands.At that time, I discovered that Mr. Lin's hands were very clean.

Then Mr. Xue also raised his hand, expressing his willingness to accept a body search, and Mr. Xue's hands were also very clean.But you have all eaten snacks, and your hands are still so clean, you must have wiped your hands.

In order to test this idea, I ate half a piece of butter puff pastry myself, and as you can see, my hands and the corners of my mouth are covered with oil.And at this time, I guessed that the real source of poison is most likely wet wipes!

Wet wipes are all for your own use. No one will reuse wet wipes that have been used by others, right?Even wet wipes that others have used, you are reluctant to touch them with your hands, because it is very unhygienic.

Therefore, the murderer uses wet wipes as a poison source, which can not only poison the deceased, but also ensure that only the deceased touches the poisonous wet wipe, and at the same time, no one else will be killed by mistake.

However, no used wet wipes were found at the scene. I thought that the waiters in this store would replace the garbage eggs more frequently, so I deduced that the poisoned wet wipes had been taken away as garbage. "

"This kid's insight and reasoning ability are still as sharp as ever!" Huang Qifa felt that he seemed to have returned to the day of the murder case in the police academy, and He Jiahui was talking and laughing like this.

"While this kid is here, we must solve the case as soon as possible."

Thinking of this, Huang Qifa asked directly: "Now that the source of the poison has been found and the method of killing is known, who will the murderer be?"

　Guys, after reading it, please ↑ a ticket, thank you for passing the test.
