Ying Mingyu, who read the confession in detail this night, found a little flaw, which was very unreasonable to him, but it did happen.

I didn't sleep well all night, and after going to work the next day, Ying Mingyu called Fang Jinshi, "Bring Liu Yiyi back for questioning." ”

"What's going on?

"There is a problem with the confession. Didn't you tell her that Chen Xiaoxiao's kettle was not poisonous, right? Liu Yiyi said that if it wasn't for the lack of water in the kettle, she wouldn't have been poisoned. ”

Fang Jinshi was stunned for a moment, "Indeed, why would she know that the water in the pot is not poisonous?"

"Ying Mingyu, it's easy to bring people back for questioning...... Even if Liu Yiyi is really a prisoner, it can be solved by losing money and settling, but ......"

"It's okay, I'm just a cousin-in-law who picked it up anyway, what should I do. ”

Fang Jinshi patted him on the shoulder and called Da Zhuang to do something.

Bao Zhan didn't want to be lazy today, he simply didn't want to get involved in this case, and he felt thankless.

"Master, didn't you still doubt Chen Xiaoxiao as much as I did yesterday, why did you change the direction of the wind today, it's too unprincipled. ”

"As I said, an investigation should follow the evidence, and intuition cannot be relied upon. ”

Liu Yiyi was really angry, sitting in the interrogation room, holding his face and puffing out his cheeks and waiting for someone to come.

Ying Mingyu chose to interrogate the person, and Fang Jinshi followed him.

"Brother-in-law, ...... you?"

Ying Mingyu knocked on the table, "Formal interrogation, my surname is Ying, just call me Officer Ying." ”

Liu Yiyi looked at the expressionless person blankly, and said no more.

"I have a very simple question for you, how do you know that the water in Chen Xiaoxiao's kettle is not poisonous?"

"Eh?!" Liu Yiyi didn't seem to expect that they would take her back to the police station for such a reason, "How do you know......"

After thinking for a while, Liu Yiyi said the answer, "Xiaoxiao told me." ”

"Last night, no, the night before yesterday, we talked about the poison in the water, a little novel, I knew that I would drink the water in her pot, and she would have played a little more in the morning, so we wouldn't have to drink bottled water, and we wouldn't be poisoned at all. ”

"Chen Xiaoxiao told you that the water in her kettle is not poisonous?"

Liu Yiyi nodded, "Didn't you tell her?" I also think it's right after she finished speaking, otherwise the water I drink is similar to Qiu Ping...... I knew that this would be better than this, I am still lying in the hospital, and I will not be wronged by you and brought to the police station. ”

"Now my classmates must think that I poisoned me, how can I go back to study in the future?" Liu Yiyi's eyes turned red when she said this, and soon tears rolled out.

Fang Jinshi subconsciously glanced at the people around her, this girl was really like Lu Qianqian when she cried, just as pitiful.

Ying Mingyu sighed, "When the matter is clear, if you haven't done it, we will naturally apologize to you and return your innocence, you don't have to worry about this." Now tell us the truth about what you can think of. ”

"You said that Chen Xiaoxiao told you that the water in the pot was not poisonous, but when we asked her last night, she didn't say anything like that. Did you say it in the dormitory, did anyone else hear it at the time?" Fang Jinshi advanced to the next interrogation.

Liu Yiyi wiped her tears and shook her head, "Shuyi doesn't live in that room, it's just me and Xiaoxiao......"

"Liu Yiyi, if you did do it, it was just a prank poisoning, and you only need other people to agree to pay compensation and settle, and you don't even need to keep a case record. I suggest you think about it and tell us ......"

Before Fang Jinshi could finish speaking, Liu Yiyi interrupted her.

"I haven't done it, I haven't done it, why should I admit that I haven't done it! Besides, why should I poison myself if I play a prank? And I have to use something as dangerous as S, and if I don't get 10mg, I'm going to die, am I crazy? I can put some croton, wouldn't that be more relieving?"

Liu Yiyi was emotional, but Ying Mingyu was very calm, and then asked her, "Who told you that S is dangerous?"

They only talked to Chen Xiaoxiao last night, maybe she learned about it from Chen Xiaoxiao's mouth, but it didn't sound like it.

"I learned in class, this kind of dangerous reagent, the teacher usually emphasizes more, everyone should know, what's strange about this. Liu Yiyi's mood calmed down slightly.

"May I ask how you usually do in chemistry class, and what about the rest of your dormitory?" Ying Mingyu completely changed direction.

Liu Yiyi didn't know what her brother-in-law meant, and said with doubts, "I'm similar to Qiu Ping, and I can get into the top ten in the class in professional classes." Comfortable in general, barely passing. Xiaoxiao is a little close, I hung up once before, because it was a professional class, and then I made up for a while to pass the make-up exam. That's what I remember, it's about the same. ”

"Understood, this testimony is very beneficial to you, we will go and verify it, please wait here for a while. Ying Mingyu comforted his cousin a little.

"Brother-in-law......" Seeing that they got up to go out, Fang Jinshi turned off the camera, and Liu Yiyi got up and shouted.

Ying Mingyu reached out and touched the girl's head, "Don't worry, if you haven't done it, we'll find out." ”

As soon as they went out, Da Zhuang came over and said something urgent, "Boss, your uncle came to the door to make trouble for a while, I invited him to sit in the conference room, can you go over and have a look?"

Liu Xiaoshuai got up early in the morning to go to school to deliver breakfast to his daughter, and when the police brought someone into the car, he immediately called Qianqian.

Lu Qianqian said that the police station should just ask his cousin to ask him according to the process, so that he didn't have to worry, but Liu Xiaoshuai couldn't listen to it at all, and kept saying that she would call Ying Mingyu, and said that she would go to the police station to protest, and finally the two hung up the phone without saying anything.

Ying Mingyu temporarily turned off the phone as early as when he gave the order to bring people back, and when he turned on the phone, he saw his uncle's three missed calls, but his wife only sent a message, saying that he should take care of it more.

With such a reasonable wife, he is still not satisfied, and the relatives who deal with the trouble have become much more acceptable.

As soon as Ying Mingyu entered the conference room, Liu Xiaoshuai denounced him for ten minutes, and he didn't let him speak.

After the man finished speaking, he opened his mouth and said the result of the inquiry just now, "We have found evidence in Liu Yiyi's favor, and we will let her go after confirming it later, please wait here for a while." ”

After going out, Ying Mingyu called Meili to help make tea and send it in, and he returned to the investigation because he felt that he had done his duty.

They called and asked the professional teacher of their class, and confirmed that Liu Yiyi said that her chemistry was very good, and she was considered to be the top in the whole college, and it was impossible for her to be unclear about the toxicity of S.

She had taken similar exams before, and Liu Yiyi's test paper records showed that she did not answer incorrectly.

If this is the case, Liu Yiyi knew the toxicity and chose to use S to poison, which can only show that her purpose is to kill people. But if she really wanted to kill, she wouldn't choose to put it in bottled water if she knew how to use it. There was a paradox here, she knew that when she was in the water, she would have a precursor to abdominal pain before she reached a dose that was enough to kill.

And if she wants to kill people in this way, but drinks a lot of water herself, there is a paradox. How could she know in advance whether the water in Chen Xiaoxiao's kettle was beaten before or after she was poisoned? What's more, Chen Xiaoxiao didn't go to class that morning, and Liu Yiyi had to be poisoned before that, so normally she would think that the water in the kettle was poisonous.

If Liu Yiyi knew about the toxicity but chose to use S to do a prank, as she said, she couldn't relieve her anger, and she was also poisoned to avoid suspicion, let alone retaliate.

Who is it that uses such a lame way to punish others, and also hurt himself, and now refuses to turn himself in and confess his guilt?

At noon, the police station invited the two fathers and daughters to a boxed lunch, and Ying Mingyu sent the two away after their investigation.

Liu Xiaoshuai was still very angry, scolded and said that he would complain to the police station in the future. Liu Yiyi is very grateful to her brother-in-law, who has been looking at him "with affection".

After the person left, Fang Jinshi joked to the people around her, "Hey, the favorability has increased instead of decreasing, this girl is stupid, she forgot that you caught her, but she only remembered that you saved her." ”

Ying Mingyu's head hurt, he didn't answer and turned around and walked back, he was almost annoyed.

Forget about other women, he can still stay away from them, this is a nominal cousin, and he plans to have a deep relationship, he can't go too far.

After Liu Yiyi returned to school, she was naturally further isolated, including Chen Xiaoxiao, no one talked to her at all, and she was already regarded as a "murderer" in private, whispering.

The tutor held a class meeting to try to mediate the conflict between the students, and it also explained that Liu Yiyi came back to prove that the police had nothing to do with her, at least for the time being, there is no evidence that she did it, but only the individual knows what the effect is.

Liu Yiyi planned to wait for the evening to talk to Xiaoxiao about what he said before, but unfortunately Chen Xiaoxiao took advantage of his money and temporarily went to live in a hotel outside the school.

With a stomach full of anger and her cousin-in-law's comfort, Liu Yiyi barely balanced, and she thought that at least one more person believed in her.

That afternoon, Ying Mingyu considered asking Chen Xiaoxiao to come back for questioning, but thinking of the futility of returning the night before, he didn't do it in the end. Any hasty action will only lead to the intensification of conflicts between students.

Children are different from adults, and it is not surprising that children do not have much social experience to know about people because they are taken to the police station for questioning.

What's more, Chen Xiaoxiao is not a timid girl who will confess if she is scared, if she insists that she didn't say those things to Liu Yiyi, or if she deduces that kind of thought, they will still do useless work.

In comparison, Liu Yiyi's statement is more honest, and she does not say that she thinks so after speculation.

The suspect can basically be locked on Chen Xiaoxiao, although there is no conclusive evidence, but after excluding others, the answer is obvious.

The next thing to do is to work backwards, look for clues that can be used as evidence from the suspect to find ironclad evidence that can prove the identity of the real murderer.

Ying Mingyu believes that the trace examination will not find nothing from so many evidence, and will definitely give them good news soon.
