He Jiahui pointed to the garbage basket, and then said: "Is there a cyanide reaction in the garbage inside, haven't you tested it yet?" ”

Everyone immediately looked at the garbage basket, and there were only a few egg tarts in the garbage basket, which should have been thrown in when someone ate egg tarts just now.

"Didn't you already test the rest of the food just now? No cyanide was found, including the remaining tarts! Huang Qiqi said with a frown.

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

Or the forensic man took the initiative to stand up: "I'd better test the contents of the garbage basket." ”

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

If the egg tart is poisonous, then the hand that picks up the egg tart will stick to the poison, and when you eat the egg tart, the mouth will also be stained with poison. This would explain why the deceased had poison on his hands and in his beer. ”

The forensic examination of the tart shells in the garbage basket for poison was obtained, and the results were available a few moments later.

"One of the tart tarts found a cyanide reaction. In addition, the fingerprints also extracted above, after preliminary comparison, found to be similar to the fingerprints of the deceased. This is most likely the egg tart that the deceased ate and the egg tart tray left behind! "Forensic evidence reported the results.

"In other words, there is poison in the tart?" Huang Qiqi asked immediately.

"No, the test results just ruled this out, because the cyanide reaction was detected only on the outside of the tart tray, where it was in contact with the hand.

However, cyanide was not detected on the inside of the tart tray, where it was in direct contact with the tart. So the egg tart should be non-poisonous. The forensic officer replied.

"Hehe, it seems that your reasoning is wrong this time, future detective! Egg tarts are not a source of poison! Huang Qiqi said in a mocking tone.

He Jiahui also frowned, and the test results did not verify his guess.

The outside of the tart tray is poisonous, but the inside is not poisonous, which indicates that the poison on the tart tray was contaminated by the deceased's hands, which means that the deceased's hands were already stained with cyanide before he ate the tart.

"What went wrong?" Ho Ka-fai's gaze swept to the table, and then his gaze rested on the other food.

In addition to the uneaten tarts, there were also uneaten cakes, durian crisps and cream pastries, 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 crisp and cream crisp be poisonous?" Both of these things also need to be picked up and eaten by hand. ”

"Haven't the durian crisps and cream cakes on the table also been tested?" Huang Qiqi said.

"I'm talking about the ones that were eaten by the deceased, if it was a poisonous durian crisp or cream crisp, then when the deceased picked it up, it would also be poisoned on his hands." Ho Ka Fai replied.

"If you say it, you don't say it!" Huang Qiqi snorted coldly: "It's all already eaten, and it's all fused with gastric juice, how can I check!" ”

"You can reason about it!" He Jiahui then asked: "Inspector Huang, if you are a murderer and want to poison one of the people at the table, how should you poison it?" ”

"That must be poisoning the food closest to him, and poisoning the food he likes the most!" Huang Qiqi replied.

"That's right, so are there any of these foods on the table that the deceased particularly liked to eat?" He Jiahui asked

"Yes! Zhenghuang likes to eat Feng Ji's cream crisp the most, which is the kind on the table, and he also ate several pieces today. Lin Zhijian replied immediately.

He Jiahui looked down and saw that the outer packaging box of the cream crisp happened to have the logo of Feng Ji.

"This crème pastry is not provided by the bar? Are you allowed to bring 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 a birthday, and we will definitely bring a birthday cake, so we can't stop guests from cutting the cake."

In general, in this case, we just turn a blind eye so as not to upset the guests. Moreover, there is a minimum consumption for this booth here, and guests also need to pay a minimum consumption regardless of whether they order something to eat or not. ”

Huang Qiqi took over the conversation at this moment, and he said: "In other words, it is possible that the murderer knew that the deceased liked to eat cream cakes, and then poisoned the cream cakes and poisoned the deceased!" ”

At this time, Assistant Teacher Xue Youlin's girlfriend suddenly spoke: "Sir, I have eaten that box of cream crisp with my boyfriend, but we are fine!" If it's poisonous, then we'll be poisoned too! ”

The forensic also spoke; "I checked it just now, and there is no reaction of poison in the remaining two pieces of cream crisp on the table."

Huang Qiqi suddenly came to his senses: "That's right, a whole box of cream crisp, even if the deceased likes to eat, but everyone will still eat it together."

If all of them were poisoned, everyone else would be poisoned, and if only one of the cream pastries was poisoned, who could guarantee that the deceased would eat the poisonous?

If he hadn't eaten the poisonous puff pastry, or if someone had taken it, the poisoned one would have been someone else.

If only one of the pieces of cream crisp is really poisonous, it means that the deceased is more unlucky and just ate the poisonous piece of cream cake.

In this way, it is very likely that the murderer's target is not the deceased, or that the murderer has no goal in the first place, this is not a targeted murder, but a random killing! ”

After Huang Qiqi finished speaking, he glanced at He Jiahui very proudly, as if to say, look at my reasoning ability, it is no worse than Ling!

He Jiahui frowned and began to think, judging from the current chain of evidence, the possibility of random murder cannot really be ruled out, unless the murderer has a way, so that the deceased will definitely be able to eat that poisonous cream cake.

"If I am the murderer, what can I do so that the deceased must eat that poisonous cream cake? Did you deliberately put the poisonous cream puff pastry right at the deceased?

No, this uncertainty is too great, even if the deceased's personal quality is better and he will take the piece in front of him to eat, but there is no guarantee that the quality of others is also good, and he will take what is in front of him.

Or maybe it's about the deceased's personal preferences? Also unlikely. A box of cream crisps is the same, and if there is something different, it is too attention-grabbing. ”

Just as He Jiahui was thinking, Huang Qiqi opened his mouth and asked: "This box of cream crisp is not provided by the bar, so who brought it?" ”

Lin Zhijian opened his mouth and replied: "The birthday cake was bought by my cousin Lin Youqiang, this cream cake, durian cake and egg tart, it seems that Liu Wei's senior sister bought it!" ”

Everyone's eyes were on Liu Wei, and Liu Wei subconsciously took a step back.

"It's not me, I'm not poisoned! I have no grievances with you, why should I poison you! Liu Wei looked like she was about to cry.

At this time, Ma Minghao, who had not spoken, suddenly stood up and said categorically: "It must not be Liu Wei who poisoned him!" ”

Ma Minghao has always been very introverted before, and even when questioned by the police, he stammered. Now he took the initiative to stand up and speak for Liu Wei, which suddenly made He Jiahui a little curious.

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

"Because...... Because ......" Ma Minghao began to stutter again, his face turned red, and he held it for seven or eight seconds before he spoke: "Because Liu Wei has always had a crush on Yu Zhenghuang, how could she poison and kill him!" ”
