In front of everyone, He Jiahui walked to the table, picked up a piece of leftover cream crisp, and tasted it directly.

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

"Jiahui, are you crazy? Don't die! Qiu Junxuan yelled beside him.

"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 it either!"

This time it was Huang Qiqi who spoke, and he also shouted loudly: "These are all evidence, don't you know? Are you crazy with hunger and eat even the evidence! This is the destruction of evidence! ”

Huang Qiqi originally hoped that He Jiahui, the god of solving the case, would take him to brush the copy, but the copy was not finished, so he destroyed the evidence first, isn't this adding to the chaos!

He Jiahui had a disapproving expression, he pointed to his mouth and said; "Inspector Huang, look!"

"What am I looking at? Watch you destroy the evidence? Or does it depend on how fragrant the food is? Also, put the evidence down! Huang Qi roared angrily.

"Yes, you didn't ask me, 'Is it really delicious?' is already an improvement."

He Jiahui teased Huang Qiqi, then put down half of the cream crisp in his hand, spread out his two hands, shook it in front of Huang Qiqi, and then asked:

"Inspector Huang, look at my hands, what's the difference from before?"

"What difference can it make, and grow a sixth finger?" Huang Qiqi snorted coldly.

"Inspector Huang, don't you see? My right hand, I just took the egg yolk crisp, and now my finger is stained with oil, and my left hand, I didn't take the egg yolk crisp just now, so it is still very clean. ”

He Jiahui pointed to his mouth again, and then said: "Not only my hands, but also the side of my mouth was stained with oil because of eating cream crisp." Well, this Feng Ji's cream crisp tastes good, but the oil is used a little too much. ”

"Nonsense, eat cream crisp, how can there be no oil that doesn't get wet!" Huang Qiqi still did not understand what Ho Ka-fai meant.

Ho Ka-fai continued; "But these companions of the deceased also ate Feng Ji's snacks, but they didn't have oil stains on their hands."

"People wiped the grease clean, can't they?" Huang Qiqi replied.

"That's right, their hands and mouths are clean, just because they have wiped it. So the question is, where are the tissues they used to wipe their mouths and hands now? He Jiahui asked with a smile.

Huang Qiqi glanced at the garbage basket, there were only a few egg tart tarts in it, and there was indeed no paper towel or anything like that.

"It's all garbage, it must have been cleaned up!" Huang Qiqi said.

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

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

"What about the garbage that was taken away from this table?" He Jiahui continued: "Now, this garbage is all evidence, and it must be found. ”

"Well...... bar's owner looked embarrassed, "the garbage is piled up in the back bin!" But we have to clean up so many bags of garbage in a day, how do I know which bag of garbage belongs to this table? ”

"It's easy, find 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 eats cream cakes either. ”

"I understand, I'll send someone to find it right away." The owner of the bar was very cooperative with the police.

The forensic also spoke: "I will go with me, lest they destroy the evidence!" ”

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

"It should be this bag, which has a tray of cream cakes, and the cream residue left on it is the same as the cake on the table." The forensic officer spoke.

"The wet wipes that should have been used in the garbage bag, right?" He Jiahui asked.

"Yes." Forensic nodded.

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

The forensic team immediately began to work, and the results were quick and clear.

"We found cyanide residues on all three wet wipes, one of which was already soaked with cyanide. The other two pieces had a small amount of cyanide on them, which should have been placed in a garbage bag and contaminated with cyanide-containing wet paper towels. "Forensic evidence reported the results.

Hearing this result, He Jiahui suddenly showed a victor's smile: "Sure enough, that wet paper towel soaked in cyanide is the real source of poison!"

The deceased must have had oil stains on his hands and mouth after eating the cream, and he needed to wipe his hands and mouth with a wet tissue, and it was the poisonous wet tissue he used.

In this way, the deceased's hands and lips are stained with cyanide, and then he eats the food with his hands, and the food will be stained with cyanide, and he will drink beer with his mouth, and the beer will also be stained with cyanide.

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! ”

"I see! This is the murderer's method of killing! Huang Qiqi breathed a sigh of relief, although he didn't know who the murderer was, but at least the source of the poison and the murderer's killing methods had been cracked.

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

"It's thanks to Mr. Lin!" He Jiahui looked at Lin Zhijian, and then said: "I have been thinking about how to make the hands of the deceased have cyanide on them.

At this time, Mr. Lin proposed that he was willing to be searched and examined, and stretched out his hands at that time. At that time, I noticed that Mr. Lin's hands were very clean.

Later, Mr. Xue also raised his hand, indicating that he was willing to accept the body search, and Mr. Xue's hands were also clean. But you've all eaten snacks and your hands are so clean, you must have wiped your hands.

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

Wet wipes are all used by themselves, and no one will take the wipes used by others and reuse them, right? Even wet wipes used by others, you don't want to touch them with your hands anymore because they are very unhygienic.

Therefore, the murderer used wet wipes as a poison source, which could not only poison the deceased to death, but also ensure that only the deceased touched the poisonous wipe, and at the same time would not accidentally kill others.

I thought that the waiters in this store would change the garbage eggs more frequently, so I deduced that the poisonous wipes had been taken away as garbage. ”

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

"While this kid is here, I have to solve the case quickly."

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