"The school girl has a crush on her senior. It's a bloody scene in a campus youth drama! But if this is true, then Liu Wei really has no motive for poisoning." He Jiahui thought to himself.

At the same time, He Jiahui secretly observed the expressions of other people. After hearing the news, everyone also had a look of disgust, but Lin Zhijian looked much calmer.

"Lin Zhijian seems not surprised that Liu Wei likes the deceased. He should have known about it for a long time!" He Jiahui thought to himself.

Huang Qifai asked directly: "Do you really have a crush on the deceased?"

Liu Wei did not answer directly, but nodded silently, and then started crying again.

Assistant coach Xue Youlin said with a sudden look on his face: "No wonder Liu Wei has been passing food to Yu Zhenghuang just now. It turns out that Liu Wei likes Yu Zhenghuang!"

Huang Qifai looked at Xue Youlin fiercely and asked: "Repeat what you just said!"

"What did I just say?" Xue Youlin was stunned at first, and then said innocently: "I said Liu Wei likes Yu Zhenghuang."

"It's not this sentence, it's the previous sentence!" Huang Qifai asked.

"I just kept giving food to Yu Zhenghuang..." Xue Youlin asked.

"Does it also include the butter puff pastry he likes?" Huang Qifa asked next.

"This..." Xue Youlin hesitated for a moment, glanced at Liu Wei, and then nodded reluctantly.

"That's it! I understand!" Huang Qifa laughed suddenly, and then said confidently: "I just thought that the murderer was a random murderer, and the deceased Yu Zhenghuang was just unlucky and ate poisonous food.

Butter puff pastry.

But it seems that is not the case now. If the butter puff was handed to the deceased by Liu Wei, then this is a murder against the deceased!

Ms. Liu Wei bought the butter puff pastry. She could have poisoned one of the butter puff pastry. When you eat the butter puff pastry, she would give the poisoned butter puff pastry to the deceased.

The deceased liked to eat butter puff pastry, so he would not refuse it. He would take the butter puff pastry and eat it. Therefore, his hands were stained with poison.

Before the poison took effect, he drank beer and ate an egg tart, so the beer was contaminated, and the beer bottle and egg tart holder were also stained with poison!"

"Sir, isn't this right? Doesn't Liu Wei have a crush on Yu Zhenghuang? Why would she poison the person she likes? This is not logical!" Assistant Xue Youlin asked.

At this time, Lin Zhijian took the initiative and said, "I guess it's probably because Zheng Huang rejected Junior Sister Liu Wei."

Another big thing is going to be exposed, and everyone has a melon-eating expression.

He Jiahui immediately said: "Mr. Lin, when Mr. Ma mentioned that Ms. Liu had a crush on the deceased, everyone was surprised, but you were the only one who was used to it. Didn't you already know it?"

Lin Zhijian nodded: "Zheng Huang and I are classmates and have the same tutor. We have classes together every day and spend more time together than with our parents, so I have known for a long time that schoolmate Liu Wei likes Zheng Huang.

And not long ago, Liu Wei learned that Zheng Huang had broken up with his girlfriend and confessed to him, but Zheng Huang did not agree to it. Later, when we were chatting, Zheng Huang mentioned this matter to me. I am not a talkative person.

People, so I didn’t tell anyone else.

Recently, the writing of Zhenghuang's thesis has not been going well. I planned to take advantage of my birthday to specially invite Liu Wei to come over, hoping to bring them together and make Zhengnan feel better. But I didn't expect...ah!"

Huang Qifai immediately looked at Liu Wei: "Ms. Liu, you poisoned Yu Zhenghuang because you confessed your love to Yu Zhenghuang and was rejected by him. Because of love and hatred, you poisoned him, right?"

"I didn't! I didn't poison!" Liu Wei cried.

"Ms. Liu, whether it was poisoned by you or not, you have to go to the police station with us! We will search your residence next, and we will notify you in advance!" Huang Qifai waved his hand and asked his men to lead him.

Let’s go to Liu Wei.

"It's really not me, I didn't do it! I was wronged!" Liu Wei continued to cry bitterly.

At this time, Ma Minghao, who was stammering, stepped forward again: "It's not Liu Wei, it's definitely not her. She has no chance of poisoning!"

"Are you so sure?" He Jiahui asked with a smile.

This Ma Minghao, who stutters when he speaks, immediately comes forward every time Liu Wei encounters trouble. He Jiahui has already seen some tricks.

"I...I..." Ma Minghao started to stutter again, and waited until his face turned red from suppressing it again before he said, "Actually, Feng Ji's butter puff pastry was not bought by Liu Wei, but by me!"

"Did you buy it? But I clearly saw that those boxes of Feng Ji's snacks were brought over by fellow junior Liu Wei!" Lin Zhijian asked with a puzzled look on his face.

Ma Minghao let out a long sigh and stammered: "I originally planned to come here directly, but before I came here, I received a call from Liu Wei, a senior student, asking me to go to Fengji to buy some snacks and bring them over. She also gave a special reminder

, let me buy butter puff pastry.

When I came over with the snacks, Liu Wei was already waiting for me at the door of the bar. She took the snacks from my hand and walked directly in. She never opened the package at all, let alone touched the butter puff inside.

.So she couldn’t have poisoned her.”

"Let you buy it? Why doesn't she buy it by herself?" Huang Qifa asked with a questioning look. He was questioning why Liu Wei didn't buy snacks by herself, but more importantly, he was questioning the authenticity of Ma Minghao's confession.

"She said she had something to do and didn't have time to buy snacks." Ma Minghao replied.

"It's too late? Are you preparing poison?" Huang Qifai began to doubt again.

He Jiahui looked at Liu Wei, whose eye shadow had turned into the same eye makeup as Jiraiya's, so he said:

"Girls, you must put on makeup when you go out, which will take some time. What's more, if you want to meet the person you like, it is common sense to dress up carefully."

Huang Qifai immediately glared at He Jiahui, as if asking, whose side are you on?

Then Huang Qifai said: "Mr. Ma, if what you said is true and Ms. Liu did not open the snack packaging box, then Ms. Liu's suspicion can indeed be eliminated, but in that case, you will be suspected.

Because you bought the snacks and brought them over, you had enough time to poison the snacks during the process."

"It's not me! I didn't poison! I came here directly after buying the snacks! I didn't open the package. Besides, why would I poison!" Ma Minghao hurriedly retorted.

"It's simple, because you like Ms. Liu Wei!" Huang Qifai snorted coldly.

Huang Qifai was not a fool. Ma Minghao, an introverted man who stuttered when he spoke, actually stood up for Liu Wei twice in a row, and was willing to be a tool to buy Feng Ji's snacks, which made it clear that he liked her.

At this time, Lin Zhijian also introduced: "Sir, Ma Minghao really likes Liu Wei. When I was in college, Ma Minghao and I were in the same class. At that time, he had a crush on Liu Wei, his junior high school student, but he didn't dare to confess. There were many people in our class who did this. Everyone knows."

"That's right!" Huang Qifa instantly possessed Maori Kogoro and said confidently: "Mr. Ma, you like Ms. Liu, and Ms. Liu likes the deceased, so you decided to kill the deceased. This is your murder. motivation!

I even have a bolder guess: when you killed the deceased, you also wanted to blame Ms. Liu, so you were taking revenge on Ms. Liu for not choosing you!"

"Inspector Huang, I think you are over-interpreting it." He Jiahui's voice sounded from the side, and he continued: "If you want to blame Ms. Liu, there is no need for Mr. Ma to stand up to defend Ms. Liu, and there is no need to admit that he was the one who went there. Bought snacks.”

Huang Qifai was stunned for a moment, and felt that he was overthinking. He immediately said: "That's the first point I made. Mr. Ma killed the deceased out of jealousy because Ms. Liu liked the deceased."

"That's not right! Because Ms. Liu didn't know that the butter puff pastry was poisonous. If Mr. Ma poisoned it, there's no guarantee that what Ms. Liu gave to the deceased was the poisonous butter puff pastry." He Jiahui's voice sounded again.

"This..." Huang Qifa suddenly looked embarrassed. He was also possessed by Mouri Kogoro, who also failed in reasoning.

The next second, Huang Qifa thought of another possibility, and he said: "It's also possible that you two conspired! Ms. Liu planned to poison the deceased because of love and hatred, and Mr. Ma was willing to help because he liked Ms. Liu. She lends a helping hand!

Mr. Ma made an agreement with Ms. Liu in advance to poison one of the snacks, and then Ms. Liu handed the poisoned butter puff pastry to the deceased, so that both of you can clear away the suspicion!"

"You're talking nonsense!"

"I don't!"

Liu Wei and Ma Minghao retorted at the same time.

"Why can't Huang Qiqi's imagination be used on the right path?" He Jiahui sighed helplessly. At this time, he already had another guess in his mind.

So He Jiahui said: "The possibility mentioned by Inspector Huang also exists, but if you want to verify it, it is actually very simple. You only need to check Ms. Liu's hands to see if there is any poison reaction.

If Ms. Liu handed the poisoned snack to the deceased, her hands must be contaminated with cyanide. We only need to test it and we will know the truth!"

"I'll check it right away," the forensic officer said.

After a while, the forensic examiner stared at the test kit and shook his head: "There is no poison reaction on Ms. Liu's hands!"

"No? How could this happen?" Huang Qifai was a little confused.

However, He Jiahui said: "It seems that our direction was wrong from the beginning. The source of the poison may not be in the food! So everyone was fine after eating snacks, and Ms. Liu did not show any reaction to the poison on her hands."

"In other words, there was no poison in the butter puff pastry I handed Zhenghuang, and it was not me who killed him!" Liu Wei's expression finally became less remorseful.

He Jiahui nodded and acknowledged Liu Wei's statement.

When detecting poisoning cases, determining the source of the poison is the most important step. At first, everyone thought the source of the poison was in the beer, and then everyone thought the source of the poison was in the food. Now that both sources of the poison have been overturned, the case has returned to its original starting point.

"There is no poison in the wine, there is no poison in the food, and the deceased did not commit suicide. So where did the poison come from?" Huang Qifai said a little discouraged.

He Jiahui was much calmer and said: "Let's review the case again. The cause of death of the deceased was cyanide poisoning, which means he must have consumed cyanide.

Our first guess was that cyanide was in the wine, but later the deceased's hands were tested for cyanide without touching the alcohol, which overturned this guess.

So we have a second guess, that cyanide is in the food. The cyanide on the deceased's hands was from when he took the food, and the cyanide in the wine was from the contamination when he drank.

All our subsequent inferences are based on this, but if there is no cyanide in the food, then the second inference has also been overturned.

We might as well reverse the second conjecture and think that the food is clean, but the hands of the deceased are not clean. The source of the poison is actually the hands of the deceased, whose hands were originally contaminated with cyanide!

And when he eats food, cyanide will be contaminated on the food, and then he will eat it, and he will be poisoned. At the same time, this speculation can also explain that cyanide reaction will occur on the can, which is

The deceased brought it with him!"

"It makes sense. If the source of the poison is the hands of the deceased, then the results of the forensic examination will make sense!" Huang Qifai showed a stunned expression and said to himself: "The problem is the cyanide in the hands of the deceased.

Where did chemical substances come from?”

Huang Qifai said, looking at Lin Zhijian.

Lin Zhijian subconsciously took a step back: "Sir, look at what I did. You wouldn't think that I was the one who poisoned Zhenghuang!"

Huang Qifai said: "Mr. Lin, during the meal, you and Miss Liu were sitting on both sides of the deceased. You were the closest to the deceased, and you were also the most likely to get cyanide on the deceased's hands.

Miss Liu has been searched just now, and her hands have been tested for poison, so Miss Liu's suspicion can be initially ruled out, and then you are the only one left."

"Then you can also search my body, and I can also do a poison test." Lin Zhijian said and stretched out his hands.

Next to him, his cousin Lin Youqiang also said: "Sir, why don't you search me too, so as not to suspect me again later!"

"There are us, we are also willing to search! As long as it can prove our innocence." Assistant coach Xue Youlin raised his hand and said.

The parties concerned have expressed their willingness to undergo a body search, so the police will naturally have no objection.

The result of the body search must have been that nothing was found. Since they took the initiative to ask for a body search, they were naturally confident and could not bring poison on their bodies.

From the beginning of the dinner party to the time of the murder, no one left, and no one carried a cyanide container with them, and there was no cyanide reaction on their hands, which eliminated their suspicions.

The source of the poison cannot be found in the poisoning case, and the case cannot be investigated further.

Huang Qifai had no choice but to look at He Jiahui. At this time, he began to look forward to whether He Jiahui could find the murderer through reasoning like the last murder case in the police academy cafeteria.
