Huang Qiqi directly asked who the murderer was, and he clearly wanted to eat a ready-made one.

He Jiahui replied: "Who provided this poisonous wet wipe, and who is the murderer!"

In the next second, Huang Qiqi immediately looked at the bar owner.

The bar owner hurriedly said: "Sir, our bar does provide wet wipes to every guest, but our wet wipes are ordered directly from the supplier, not produced by us."

And I don't know the dead at all, so why poison him! Besides, I opened a store, how could I commit murder in my own store? If a customer dies in my shop, business will definitely be affected, and I am also a victim! ”

Huang Qiqi nodded, from the perspective of motivation, it is indeed unlikely that the store will be poisoned.

"Where do you source your wipes from? What is the contact information of the supplier? Huang Qiqi asked, obviously a little suspicious that something was wrong with the supplier.

"Yes, I'll go get the supplier's contact information right away." The bar owner spoke.

He Jiahui picked up an unopened wet wipe from the table next to him, looked at the production information on it, and said: "This is produced by a regular manufacturer, and the quality of the product should be no problem."

Even if it is contaminated with toxic cyanide during the production process, it is impossible to contaminate only one paper towel, at least one small batch must be contaminated.

In the same way, if contamination occurs during transportation and sales, it is impossible to contaminate only this piece of tissue. So it's almost certain that it shouldn't have anything to do with the production and sales process. ”

"Is that a targeted poisoning murder?" Huang's thinking is finally on the right track.

He Jiahui said: "I judged that the murderer prepared the poisonous paper towel in advance, and then found an opportunity to exchange it with the paper towel in front of the deceased. ”

"You're a bit broad, aren't you? This is the bar, this is full of people, wet wipes are on the table, and who knows when they will be replaced. Huang Qiqi said.

He Jiahui turned his head and asked forensics: "How many tissues were found in the garbage bag?" ”

"Let me count...... Eight sheets! The forensic officer replied.

"In that case, the scope is much narrower, and the murderer is among the companions of the deceased." He Jiahui replied.

"Why?" Huang Qiqi asked another provocative question.

He Jiahui slowly explained: "Including the deceased, there are seven people at this table, so the store will also prepare seven packs of wet wipes, but there are eight used wet wipes in the garbage.

This shows that after the murderer exchanged the poisonous wet wipes for the deceased, he also used up the non-toxic wet wipes that he had exchanged. I guess the killer did this because he was afraid that an extra pack of unopened wet wipes would arouse suspicion.

And the only ones who can do this are the six friends of the deceased, and even if the others have the ability to exchange the toxic wet wipes, it is impossible to put their used wet wipes into the garbage basket on this table. ”

"That's right." Huang Qiqi nodded.

After going around in a circle, the case returned to its original track, and the murderer was among the six companions of the deceased.

It's just that unlike before, this time there is a conclusive evidence of wet wipes.

The six companions of the deceased are also you look at me, I look at you, and each other's eyes are full of suspicion, and at this time they are probably also guessing who the real murderer is.

He Jiahui's gaze swept over everyone, and finally fell on Lin Zhijian.

Lin Zhijian still performed the same way last time, and said with an unconvinced face: "Sir, what do you think I do?" It's not my poison! Why do you always doubt me! ”

He Jiahui opened his mouth and said, "Mr. Lin, the deceased is sitting next to you, and you are the closest to the deceased, so in terms of the difficulty of changing wet wipes, you should be the easiest." ”

"According to what you say, Liu Wei is also sitting next to Zhenghuang! She can also swap wet wipes! Didn't you just say that Liu Wei is very likely to kill people out of love and hatred, and she has a motive. Lin Zhijian opened his mouth to retort.

"Mr. Lin, don't be in a hurry to defend yourself, I haven't finished talking yet!" He Jiahui smiled faintly, and then said: "You organized this party, and you invited the deceased to participate, right?" ”

"So what? Isn't it normal for me to celebrate my birthday and invite a few friends to celebrate together? I'm so familiar with Yu Zhenghuang, if I don't invite him, I can't say it! Lin Zhijian said.

"So you, as the organizer of the party, were the first to arrive here, right? You have the most time to swap out the wipes. ”

He Jiahui paused, and then asked Liu Wei: "Ms. Liu, I heard Mr. Ma say before that Feng Ji's dim sum was bought by you for him, why did you think of buying dim sum?" ”

Liu Wei thought for a while and replied: "That's right, when school was about to get out of school this afternoon, I suddenly received a call from Senior Brother Lin (Lin Zhijian), saying that he had a birthday and invited me to the party, and also told me that Senior Brother Yu (the deceased) would also come."

At that time, I said, why didn't you inform me earlier, I can prepare a gift, Senior Brother Lin said, they are all so familiar, there is no need to buy gifts, and he also said that he was afraid that the birthday cake was too small to eat, so let me buy some snacks!

Because it was almost out of school, I had to go back to put on makeup, and I was afraid that I would be too late, so I asked Senior Brother Ma for help and went to Feng Ji to buy a few snacks for me. ”

He Jiahui nodded suddenly: "In other words, it is not your idea to buy Feng Ji's dim sum, but Mr. Lin's idea." And this also means that the reason why you can eat these snacks at the party is actually arranged by Mr. Lin in advance.

This illustrates a point even more, Mr. Lin knew in advance that he needed to use his hands to get snacks to eat at the party, so wet wipes would inevitably be used. Then Mr. Lin is also the most likely to prepare toxic wet wipes. ”

Reasoning to this point, Lin Zhijian's suspicion is indeed the greatest.

Everyone looked at Lin Zhijian with puzzled eyes, but Lin Zhijian had an angry expression, and he said: "This is just nonsense! According to what you say, if you know that you have a little heart to eat at the dinner, you are the murderer, then Senior Sister Liu Wei also knows!

When I asked her to buy dim sum, she already knew that she could eat dim sum at today's dinner, and she could also prepare toxic wet wipes to poison Yu Zhenghuang! She's just as suspicious as me, why did she put her hat on my head! ”

"Mr. Lin, don't worry, what I just said is just speculation, who is the real murderer, you still have to look at the evidence!" He Jiahui said with a smile.

"That's right, the police have to talk about evidence when handling cases, and if you accuse me of being a murderer, you have to come up with evidence! Proof, do you have it! Lin Zhijian said a little domineeringly.

He Jiahui put on a serious expression: "Of course I have evidence!" Without evidence, how could I be here to talk nonsense with you! ”
