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, it tastes really good." He Jiahui said to himself.

"Jiahui, are you crazy? You don't want your life!" Qiu Junxuan shouted from the side.

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

"Then you can't eat it either!"

This time it was Huang Qifai 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 Qifai originally expected He Jiahui, the master of crime-solving, to help him clear the copy, but before the copy was finished, he destroyed the evidence first. Isn't this adding chaos!

However, He Jiahui had a nonchalant expression on his face. He pointed to his mouth and said, "Inspector Huang, look!"

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

"That's right. You didn't ask me, 'Is it really delicious?' This is already an improvement."

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

"Inspector Huang, look at my hands. Are they any different from before?"

"What difference can it make? Can you grow a sixth finger?" Huang Qifai snorted coldly.

"Inspector Huang, didn't you see? My right hand just took the egg yolk cake, and now my fingers are stained with oil, and my left hand didn't hold the egg yolk cake just now, so it's still clean."

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

many."

"Nonsense, how can you eat butter puff pastry without being stained with oil?" Huang Qifai still didn't understand what He Jiahui meant.

He Jiahui continued: "But these companions of the deceased also ate Feng Ji's snacks, but there was no oil stain on their hands."

"I just wiped the oil stains clean, couldn't I?" Huang Qifai replied.

"That's right. Their hands and mouth are very clean because they have wiped them. So the question is, where are the tissues 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 indeed there were no paper towels or anything like that.

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

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

Especially when a customer orders a fruit plate, the garbage must be cleared away in time, otherwise the sweetness of the fruit will attract some small flying insects, affecting hygiene and affecting the guest's appetite."

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

"Well..." the bar owner showed a troubled expression: "The garbage is piled up in the trash can at the back! But we have to clean up 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: "Except for this table, no one else has a birthday today, right? No one else.

Eat cream cake."

"I understand, I'll send someone to look for him right away." The bar owner was very cooperative with the police.

The forensic officer also said: "I will go with you to prevent them from destroying the evidence!"

The cream cake tray was an obvious feature, and it didn't take long for forensics to find the bag of garbage.

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

"There should be used wet wipes in the garbage bag, right?" He Jiahui asked.

"Yes." Fa Zheng nodded.

He Jiahui said: "Please test these wet wipes and see which one has cyanide reaction."

The forensic team started working immediately and the results were soon available.

"We found cyanide residues on all three wet wipes. One of the wet wipes was soaked with cyanide. The other two had a small amount of cyanide locally. They should have been placed in garbage bags and were covered with cyanide.

The chemical wet wipes were contaminated." The forensic evidence reported the results.

Hearing the result, He Jiahui suddenly showed a victor's smile: "As expected, the wet tissue soaked in cyanide was the real source of the poison!

After eating the butter puff pastry, the deceased must have had 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 poisonous wet tissue.

In this way, the deceased's hands and lips will be stained with cyanide. Next, if he eats food with his hands, the food will be stained with cyanide. If he drinks beer with his mouth, the beer will also be stained with cyanide.

Contaminated with cyanide.

And whether he eats or drinks beer, cyanide will be in his stomach, which means that as long as he uses this poisonous tissue, he will definitely die!"

"So that's it! This is the murderer's murder method!" Huang Qifa let out a sigh of relief. Although he still didn't know who the murderer was, at least the source of the poison and the murderer's murder method had been solved.

Then Huang Qifai asked: "How did you come up with the idea of ​​wet wipes?"

"Thanks to Mr. Lin!" He Jiahui looked at Lin Zhijian and continued: "I have been thinking about how to get the hands of the deceased covered with cyanide.

It happened that at this time, Mr. Lin proposed that he was willing to be searched and examined, and at that time he extended his hands. I discovered at that time that Mr. Lin's hands were very clean.

Then Mr. Xue also raised his hand to express his willingness to be searched, and Mr. Xue's hands were also very clean. But you have all eaten dim sum, and if your hands are still so clean, you must have wiped them.

In order to test this idea, I personally ate half a piece of butter puff pastry. As you all saw, my hands and the corners of my mouth were all stained with oil. At this time, I guessed that the real source of the poison was very

Maybe wet wipes!

Wet wipes are for your own use. No one would reuse wet wipes that have been used by others, right? Even wet wipes that have been used by others, you are not willing to touch with your hands again, because they are very easy to use.

Unhygienic.

Therefore, the murderer used wet wipes as a source of poison, which can not only poison the deceased, but also ensure that only the deceased touches the poisonous wet wipes, and at the same time, other people will not be accidentally killed.

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 poisonous wet wipes had been collected as garbage."

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

"While this kid is here, we must solve the case quickly."
