He Jiahui pointed to the garbage basket and continued: "You haven't tested whether there is any cyanide reaction in the garbage inside, right?"

Everyone immediately looked at the trash can. There were only a few egg tart holders in the trash can, which must have been thrown in when someone was eating egg tarts just now.

"Didn't you just test the remaining food? No cyanide was found, including the remaining egg tarts!" Huang Qifai said with a frown.

"But you can't rule out that there is no cyanide in those egg tarts that have been eaten!" He Jiahui said.

It was forensics who took the initiative and said, "I'd better test the contents of the trash basket."

He Jiahui explained: "If one of the egg tarts is poisonous, it means that the egg tart on this tray is also poisonous.

If the egg tarts are poisonous, then the hands that pick up the egg tarts will be stained with poison, and when eating the egg tarts, the poison will also be stained on the mouth. This can explain why the hands of the deceased and the beer are stained with poison. "

Forensics conducted a poison test on the egg tart shells in the garbage basket, and the results were available within a few minutes.

"Cyanide reaction was found in one of the egg tart trays. In addition, the fingerprints also extracted from it were found after preliminary comparison to be similar to the fingerprints of the deceased. This is probably the egg tart tray left behind by the egg tarts eaten by the deceased!" Forensics reported the results.

"In other words, the egg tarts are poisonous?" Huang Qifai asked immediately.

"No, the test results exclude this precisely because the cyanide reaction was detected only on the outside of the tart holder, where it comes into contact with the hands.

But no cyanide was detected where the inside of the egg tart holder was in direct contact with the egg tart. So the egg tart should not be poisonous," Forensic replied.

"Haha, it seems your reasoning is wrong this time, Future Detective! Egg tarts are not the source of the poison!" Huang Qifai said in a mocking tone.

He Jiahui also frowned. The test results did not confirm his guess.

The outside of the egg tart holder was poisonous, but there was no poison inside. This means that the poison on the egg tart holder was contaminated by the deceased's hands, which means that the deceased's hands were already stained with cyanide before he ate the egg tarts.

"What exactly went wrong?" He Jiahui glanced at the table, and then stopped at other foods.

In addition to the unfinished egg tarts, there were also uneaten cakes, durian cakes and cream cakes, as well as potato chips and fruits on the table.

He Jiahui immediately thought of another possibility, and he said: "If there is no poison in the egg tart, then will the durian cake and butter cake be poisonous? These two things also need to be picked up and eaten with hands."

"Haven't the durian cakes and butter cakes on the table been tested?" Huang Qifai said.

"I'm talking about the ones eaten by the deceased. If they are poisonous durian cakes or butter cakes, then when the deceased picks them up, his hands will be stained with poison." He Jiahui replied.

"You said it, but you didn't say it!" Huang Qifai snorted coldly: "I have already eaten it and it has been fused with the gastric juice. How can I check it!"

"It can be done through reasoning!" He Jiahui then asked: "Inspector Huang, suppose you are the murderer and want to poison one of the people in the table, how should you poison him?"

"Then it must be to poison the food closest to him, and also to poison the food he likes to eat the most!" Huang Qifai replied.

"Yes, so among the foods on the table, are there any that the deceased particularly liked to eat?" He Jiahui asked.

"Yes! Zhenghuang likes Feng Ji's butter puff pastry the most, the one on the table. He also ate several pieces today." Lin Zhijian replied immediately.

He Jiahui lowered his head and saw that there was Feng Ji's logo on the outer box of the butter puff pastry.

"Isn't this butter puff provided by the bar? Do you allow bringing your own food here?" He Jiahui asked immediately.

The person in charge of the hotel next to him immediately replied: "In principle, we do not encourage guests to bring their own food, but this table is celebrating a birthday and will definitely bring a birthday cake. We can't stop the guests from cutting the cake."

Normally in this situation, we just turn a blind eye to avoid upsetting the guests. Moreover, the booths here originally have a minimum consumption, and the guests still need to pay the minimum consumption regardless of whether they order something or not."

Huang Qifai took over the conversation at this moment and said: "In other words, it is possible that the murderer knew that the deceased liked to eat butter puff pastry, and then he poisoned the butter puff pastry and poisoned the deceased!"

At this time, the girlfriend of assistant teacher Xue Youlin suddenly said: "Sir, my boyfriend and I have eaten that box of butter puff pastry, but we are both fine! If there is poison in it, wouldn't we also be poisoned to death?"

!”

The forensic officer also said, "I just tested it, and there is no reaction of poison in the two pieces of butter puff pastry left on the table."

Huang Qifai suddenly came to his senses: "That's right, even if the deceased liked to eat a whole box of butter puff pastry, everyone would still share it.

If they are all poisoned, the others will also be poisoned. If only one of the pastries is poisoned, who can guarantee that the one the deceased eats must be the poisoned one?

If he didn't eat the poisonous butter puff pastry, or if it was taken away by someone, someone else would be poisoned to death.

If only one piece of butter puff pastry is really poisonous, then the deceased was unlucky and happened to eat the poisonous butter puff pastry.

In this case, the murderer's target is very likely not to be the deceased, or the murderer has no target in the first place. This is not a targeted murder, but a random killing!"

After Huang Qifai finished speaking, he glanced at He Jiahui very proudly, as if to say, look at my reasoning ability, it's not worse than yours!

He Jiahui frowned and began to think. Judging from the current chain of evidence, the possibility of random killings cannot be ruled out, unless the murderer has a way to ensure that the deceased can eat the poisonous butter puff pastry.

"If I were the murderer, what method should I use to ensure that the deceased would definitely eat the piece of poisonous butter puff pastry? Should I deliberately point the poisonous butter puff pastry directly at the deceased?

No, this is too uncertain. Even if the deceased's personal quality is better, he will take the piece in front of him, but there is no guarantee that the quality of others is equally good, and he will take the piece in front of him.

Or maybe it was based on the deceased's personal preferences? It's unlikely. Every box of butter puff pastry is the same, and if something different appears, it will be too noticeable."

While He Jiahui was thinking, Huang Qifai asked: "This box of butter puff pastry is not provided by the bar, so who brought it?"

Lin Zhijian replied: "The birthday cake was bought by my cousin Lin Youqiang. The butter puff pastry, durian puff pastry and egg tarts seem to have been bought by schoolmate Liu Wei!"

Everyone looked at Liu Wei, and Liu Wei subconsciously took a step back.

"It's not me, I didn't poison you! I have no enmity with you, why would I poison you?" Liu Wei looked like she was about to cry.

At this time, Ma Minghao, who had been silent all this time, suddenly stood up and said categorically: "It was definitely not Liu Wei who poisoned me!"

Ma Minghao had always been very introverted before, even stammering when asked by the police. Now he took the initiative to speak for Liu Wei, which immediately made He Jiahui a little curious.

"Mr. Ma, how can you be so sure that it wasn't Liu Wei who poisoned you?" He Jiahui asked.

"Because...because..." Ma Minghao started to stutter again. His face turned red. He held it in for seven or eight seconds before he said, "Because Liu Wei has always had a crush on Yu Zhenghuang, how could she poison her?"
