Detective: Open your eyes, I am handcuffed in the interrogation room

There is a small pavilion not far outside the dormitory building. Unknown plants spread and grow on the building materials, adding vitality.

You don't need to think about it to know that at night there will inevitably be couples here, writing about the sweet love in college.

A few people randomly found a place to sit down. It was noon and there were very few people around.

Zhai Yiling is over 1.6 meters tall, with healthy wheat-colored skin and long hair.

The straight bridge of her nose adds a bit of three-dimensionality to her face. The genetics of a mute woman are vaguely visible in her appearance. Although her clothes are simple, they are very neat and clean.

From the appearance, everyone knows that this is a girl from the countryside.

Facing the police, Zhai Yiling was a little cautious, not because of her status as a police officer, but because of her personality.

Rural people have low self-esteem that is not easy to detect, but Zhai Yiling also has the desire and pursuit for the future. Knowledge changes destiny. University is a good springboard to realize the value of one's life and change one's destiny.

The cautious expression allowed Chen Yi to see Zhai Yiling's inferiority complex and tenacity. These two words did not conflict with each other.

After a moment of silence, he thought he should be tactful, not only to ensure that Zhai Yiling would not be harmed, but also to ensure that he knew as much as possible.

"Do you know about the mute girl in Donghua Village?"

Chen Yi got to the point.

Zhai Yiling nodded slightly: "I know."

Chen Yi: "What's your impression of her?"

Zhai Yiling thought for a while and said: "She has been in Donghua Village since I can remember. She is so stupid and can't talk every day. She still smiles when she sees me. I am quite afraid of her."

These words made He Xin and the others sigh secretly. For a moment, they couldn't tell whether the truth or a white lie was more important.

Chen Yi continued to ask: "Lu Qiucheng, do you know him?"

When Lu Qiucheng was mentioned, Zhai Yiling frowned: "We know him."

She is not a girl who can hide her emotions, and there is no need to hide her emotions. Everyone present can see that she is not cold towards Lu Qiucheng, and even dislikes her.

Chen Yi: "How is your relationship with him?"

Zhai Yiling shook her head: "Not very good."

Chen Yi: "Can you tell me more specifically?"

Zhai Yiling hesitated for a long time, maybe she felt that she couldn't hide anything from the police, so she replied: "Qiu Chengdu has been very good to me since I was a child. He often buys me things and gives me money after work. I have always regarded him as Big brother looked at it and found out later that he was plotting against me!"

"Planning something evil?" Chen Yi felt that he had grasped the key to this case. "What does it mean to plot something evil? Has he done anything to you?"

Zhai Yiling: "That's not true. His kindness to me is all fake and he wants to do evil to me."

Chen Yi: "How did you know?"

Zhai Yiling: "It's a very simple reason. We are not relatives, why is he so nice to me? There are so many children in the village, why does he only treat me differently? He must be dirty in his heart."

Chen Yi looked at the side face of the girl in front of him and thought that the other party's logic was not quite right and a bit extreme. A girl who had just entered college would not think so darkly of others casually.

Unless Lu Qiucheng did something or said something.

He asked: "When did you start having this idea?"

Zhai Yiling: "Ever since...someone told me, the more I think about it, the more wrong it becomes."

Chen Yi's eyes flashed: "Someone else? Who?"

Zhai Yiling: "There is an uncle in the village named Ma Yilong."

Hearing Ma Yilong's name again, and again from Zhai Yiling, caused Chen Yi's thinking to become confused for a moment. After the confusion, there was a change in the analysis of the case.

"Did Ma Yilong tell you that Lu Qiucheng had evil intentions against you?"

Zhai Yiling nodded.

Chen Yi: "Lu Qiucheng has never done or said anything, yet he is still very kind to you?"

Zhai Yiling nodded again.

When asked about this, Chen Yi and He Xin looked at each other. They both felt that there was a problem here, a big problem.

The crux of the issue is whether what Ma Yilong said is true.

In fact, although Zhai Yiling's logic is extreme, it is still reasonable. It is indeed questionable to be nice to a girl for no reason. Coupled with other people's encouragement, Zhai Yiling, who is careless, decisively believed it.

However, as long as Zhai Yiling's life experience is known, Lu Qiucheng's behavior can be explained.

Lu Qiucheng has a very good relationship with the mute girl, and Zhai Yiling is the daughter of the mute girl. It is understandable that Lu Qiucheng loves the house and Wu and loves Zhai Yiling.

Zhai Yiling is not clear about this matter.

So, did Ma Yilong lie?

If he hadn't lied, Lu Qiucheng was upright on the surface but dirty inside. Ma Yilong, who discovered the truth, couldn't stand it anymore.

If he lied, the relationship between Ma Yilong and Lu Qiucheng was not as good as the former said, and their purpose was not pure.

"Have you and Lu Qiucheng fallen out?" Chen Yi asked.

Zhai Yiling: "I fell out."

Chen Yi: "When?"

Zhai Yiling recalled: "It was about two months ago. He came to see me at school and said he bought me some clothes. I had a big fight with him and asked him why he was so nice to me and whether he had any thoughts about me."

Chen Yi: "What was his reaction?"

Zhai Yiling: "Of course he denies it. He held me back and refused to let me go unless I made it clear. I yelled to call the police before I escaped. I have never seen him again since then."

Chen Yi was silent for a moment and said, "Without real evidence, you haven't thought about the possibility of making a mistake?"

Zhai Yiling turned around and said, "How is that possible? Uncle Ma told me that it was Lu Qiucheng who told Uncle Ma the truth after drinking. Could this be a mistake? Besides, it is doubtful that he is so good to me. Why? "

Chen Yi: "What if Ma Yilong lied?"

Zhai Yiling was stunned, choked, and said, "Uncle Ma won't lie. There is no reason. What good will it do to him?"

While chatting here, Chen Yi's cell phone rang.

"Excuse me for a moment."

Chen Yi said something, answered the phone, and told Fang Shuyu his location.

After a while, Fang Shuyu came to the small pavilion carrying the forensic box.

Zhai Yiling looked over and thought to herself, this sister is really pretty. Is she also a police officer?

"Zhai Yiling, we need to extract your DNA, is that okay?" Chen Yi said.

Now that the mute girl's daughter has been found, the next step is to identify the mute girl's father. Regardless of whether it is related to the case or not, a comprehensive investigation is needed, not to mention that it may involve rape.

Eighteen years, the maximum prosecution period has not passed yet, even if it has passed, it can still be reported to the Supreme People's Procuratorate for approval.

Investigating a crime means casting a wide net, and the truth is often hidden in inconspicuous corners of the net.

When she heard that DNA was to be extracted, Zhai Yiling was a little confused: "What...what are you doing? Police uncle, what case are you investigating? Does it have anything to do with me?"

Only then did she ask her confusion, what case would involve her? ?

Chen Yi: "It's a big case. I hope you can cooperate. Don't worry, it's not a blood draw, it's just a slight scraping of the oral mucosa."

Zhai Yiling did not dare to refuse: "Okay... okay."

Chen Yi looked at Fang Shuyu. Fang Shuyu stepped forward to open the forensic box, took out a cotton swab, stirred it in Zhai Yiling's mouth, and put it into the container.

Zhai Yiling felt quite uneasy. The police came to inquire and extracted DNA. She didn't know what happened. The unknown is the scariest thing.

After that, Chen Yi asked some other questions and determined that the biggest variable in Zhai Yiling's life was Lu Qiucheng, and the group left Yangcheng University.

Fang Shuyu returned to the city bureau alone. She needed to conduct a paternity test on Zhai Yiling and the mute girl as soon as possible. Ma Yilong's words needed to be confirmed with authoritative evidence. This is the basic principle of police investigation.

Back in the car, the car did not start immediately. Chen Yi sat there quietly and began to analyze the entire case based on the clues he had so far.

First of all, it is a fact that the mute woman killed Lu Qiucheng with a hammer. What needs to be clarified now is her motive and why she killed Lu Qiucheng.

After questioning Zhai Yiling just now, we have already made a breakthrough.

It may be to vent her anger on Zhai Yiling, whose poor cognitive ability leads to extreme behavior.

So the question is, is Lu Qiucheng really plotting against Zhai Yiling?

There was no verbal teasing, no behavioral harm. To put it bluntly, it was all Zhai Yiling's fault, and the reason for the fault came from Ma Yilong.

The second question came, echoing the first question, whether what Ma Yilong said was true.

Let’s first assume it’s true.

Lu Qiucheng's feelings for Zhai Yiling are not love and affection, but purely evil thoughts in his heart. He is only nice to Zhai Yiling so that he can one day get his hands on her.

Based on this assumption, two doubts arise.

The first doubtful point is that according to Zhai Yiling, Lu Qiucheng has been very good to her since she was a child. This is wrong. Would a man have any thoughts about a very young child? Developing a psychology?

Or is it that Lu Qiucheng's brotherly relationship with Zhai Yiling gradually changed in a distorted way as Zhai Yiling grew up and became taller and taller?

The second doubtful point is that Lu Qiucheng was not physically or verbally aggressive. How did the mute girl know? Did Ma Yilong tell her? If so, for what purpose did you tell her?

Suppose again that it is false.

Lu Qiucheng was like a brother to Zhai Yiling, and there was no so-called evil intention at all. Ma Yilong lied.

Why lie? There are many possibilities, such as dislike, envy of the brother-sister relationship between the two, or Ma Yilong may even be the one who has thoughts about Zhai Yiling.

If this is the case, why would the mute woman know? Ma Yilong's purpose in telling the mute girl is even more illogical.

If we rely on the murder case, there is another inference: Ma Yilong deliberately created the illusion that Lu Qiucheng bullied Zhai Yiling, and then told the mute girl, which eventually led to the mute girl's beloved daughter being so angry that she killed Lu Qiucheng with a hammer.

When the inference appeared in Chen Yi's mind, everything seemed to fall into place and all doubts disappeared.

Ma Yilong took advantage of the mute girl's low IQ and her mentality that she would sacrifice everything for her daughter to instigate the murder and create this tragedy.

is that so?

If you want to confirm or strengthen your suspicions, you need to investigate the relationship between the two in depth and find out the motive.

As long as there is a sufficient motive, Ma Yilong is extremely suspicious.

In the car, He Xin waited for a long time and couldn't help but said: "Chen Yi, should we find Zhai Yiling's biological father next? Inform the police station again?"

Chen Yi came to his senses and raised his hand to stop: "No, go to Zhongda Technology again and drive."
