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

On the balcony, an old man and a young man sat down.

Although Chen Yi was suspicious of Lou Meiying, he did not deliberately target her out of respect for the old man. He hoped to obtain more unknown clues about Gao Xiaofei through insinuations.

"Let's start talking...before the fire happened." Chen Yi started.

Lou Meiying sighed deeply, unwilling to recall in every possible way, so she could only continue the topic helplessly: "That was... when Xiaofei was in elementary school."

primary school?

Chen Yi was slightly stunned and interrupted: "Ms. Lou, did you remember correctly? The fire happened in the junior high school."

"Junior high school?" Lou Meiying was confused, "It should be junior high school, I can't remember clearly."

Chen Yi paid attention to Lou Meiying's expression and reaction. It was not like he was pretending. The fire was the most unforgettable memory, so he would not remember the wrong time.

Is it...a symptom of Alzheimer's disease?

The spirit suffers a major blow and the mood fluctuates violently. Over time, it will lead to abnormal mental state, memory impairment and other problems may occur, and induce Alzheimer's disease.

Judging from Lou Meiying's condition, it is still relatively normal. Even if there are signs of Alzheimer's disease, it is not too serious.

Chen Yi didn't pay attention and said, "It was indeed junior high school. Gao Xiaofei was quite rebellious at that time."

Lou Meiying: "Oh... I remembered it, but I was confused. It was junior high school, and Haohao went to elementary school."

Haohao is Gao Xiaofei's younger brother.

Chen Yi judged that the reason why Gao Xiaofei became rebellious was that his younger brother should account for a certain proportion of the reason. This was not a preference for boys over girls, but a preference for the younger son. The same was true when the gender was reversed. It is difficult for a family with two or three children to have a bowl of water. Duanping, it mainly depends on how the parents handle it.

Children's hearts are very sensitive.

"What was the cause of the fire?" Chen Yi asked.

Lou Meiying: "It was Haohao's birthday. Maybe the candle caught fire. The fire department said the candle burned first."

Chen Yi: "Where did it burn?"

Lou Meiying: "I remember it was the living room."

Chen Yi: "It's night, right?"

Lou Meiying: "Yes."

Chen Yi began to automatically construct a 3D fire model in his mind. At night, after everyone fell asleep, the candles in the living room began to burn. An accidental factor ignited the source of the fire, and the fire began to spread.

When Gao Xiaofei's parents discovered that there was a fire in their home, they were unable to control the fire. Everyone in the family except Gao Xiaofei died in the fire.

So the question is, how do candles burn out of thin air? After the birthday is over and everyone goes to sleep, someone must have lit the candle.

The most likely one is Gao Xiaofei.

The scene changed. Late at night, Gao Xiaofei walked out of the bedroom and came to the living room. She sat there and lit birthday candles, feeling very sad.

Why are you sad?

Parents care about their younger brother but not themselves, so their parents celebrate their younger brother's birthday but not themselves?

"When Xiao Fei's birthday is over, will the whole family celebrate her?" The scene ends and Chen Yi asks.

Lou Meiying: "When I was young, we had it every year. I was with them, but I didn't know about it later."

Chen Yi: "How young were you when you were a child, before junior high school?"

Lou Meiying: "Absolutely."

Chen Yi: "The candles are burning at night, who lit them?"

Regarding this question, Lou Meiying was silent for a few seconds and said, "Haohao."

Chen Yi: "How did you know?"

Lou Meiying: "Xiao Fei said she didn't order it, so it must have been Haohao. Children all like to play with fire."

Chen Yi: "What if Gao Xiaofei lied?"

Back then, Gao Xiaofei was a rebellious girl, and she must have been very good at telling lies. Let alone being rebellious, even a child with excellent morals and academics could not guarantee that everything she told was the truth.

Lou Meiying turned to look at Chen Yi: "Young man, is there any point in asking who lit the candle now? The fire has already happened. It doesn't matter whose fault it is between the siblings."

Chen Yi looked at her: "It makes sense, Gao Xiaofei is still alive and has grown up."

Lou Meiying looked confused, as if she didn't understand what Chen Yi wanted to express.

Chen Yi didn't know whether Lou Meiying was good at acting or had nothing to do with the case. In the process of trial and error, the police must not be swayed by emotions and must be ruthless.

To put it bluntly, Lou Meiying has lived for most of her life and has eaten more salt than she has walked. If she is really a suspect in this case, it will not be easy to deal with.

"If Gao Xiaofei caused the fire, would you hate her?" Chen Yi proposed a hypothesis.

Lou Meiying still didn't understand Chen Yi's intention. She thought the other party was chatting, so she turned her eyes to look out the window and said: "They are all children, I don't hate them, Haohao or Xiaofei, their lives have nothing to do with them. "

Chen Yi hesitated and gave up his plan to defraud Lou Meiying.

Not much information was obtained from the brief conversation, but one thing is very important: Lou Meiying seemed to suspect that Gao Xiaofei caused the fire.

The word "suspicious" is very subtle. One step forward means confirmation. Maybe Lou Meiying already knew that Gao Xiaofei lit the candle, but she lied and said she didn't know clearly or that it didn't matter.

He continued to chat with Lou Meiying about the fire.

"How did Gao Xiaofei escape?"

Lou Meiying closed her eyes, tears welling up in the corners of her eyes: "It was her father who rescued her. Her bedroom was closest to the door. After she was rescued, her father ran back to save the mother and son at home, and none of the three came out again. "

As soon as these words came out, the atmosphere became silent.

A father is a father after all. Even if there is a deviation in life, he will not hesitate to save his daughter in an emergency.

A son and a daughter are the same. They are both children. There is no difference. He can use his life to exchange for the safety of his siblings.

It is conceivable that if the fire was caused by Gao Xiaofei, then when she saw her father saving her without hesitation and seeing her father buried in the sea of ​​fire, she would feel so much regret.

As for lying...

It was a self-psychological protection that a junior high school kid used under extreme panic and fear.

At this point, Chen Yi had a rough inference about the entire incident.

It was Haohao's birthday nine years ago. The whole family bought cakes and candles to celebrate Haohao's birthday. Everyone was very happy except Gao Xiaofei.

Since Haohao was born, Gao Xiaofei has received less and less attention. She is angry, jealous, and hates this younger brother. At the same time, she is also sad that her parents have not given her a birthday for a long time.

Especially as she became more and more rebellious and disobedient, she felt that everyone around her disliked her and that everyone was prejudiced against her.

That night, the sad and crying Gao Xiaofei tossed and turned and couldn't sleep. She got up from the bed and went to the living room in the middle of the night. She lit the remaining candles and missed her parents who used to cling to her and sing happy birthday to her.

The fire broke out and Gao Xiaofei woke up from her sleep. The fire was already too big to control. Her father picked her up and rushed out of the fire without hesitation, using his body to resist the relentless fire. In the end, Gao Xiaofei only suffered burns on her arms.

After Gao Xiaofei was safe, her father rushed into the sea of ​​fire again and never came out.

She regretted, she broke down, she lied and said she didn't light the candle herself.

Lou Meiying continued to raise Gao Xiaofei on behalf of her son.

Gao Xiaofei has experienced chronic iron poisoning, and there are many possibilities here.

The first possibility is that Lou Meiying did not know that the fire was caused by Gao Xiaofei, but she had suspicions and could not accept the death of her family members. She transferred her anger to Gao Xiaofei and used diet to poison Gao Xiaofei for a long time. She did not kill the person.

The second possibility is that Lou Meiying did not know that the fire was caused by Gao Xiaofei, but she had suspicions and could not accept the death of her family members. She passed her anger on Gao Xiaofei. She poisoned Gao Xiaofei with iron through diet for a long time, and finally replaced her with trivalent arsenic to kill her.

The third possibility is that Lou Meiying did not know that the fire was caused by Gao Xiaofei at first, but was very angry when she found out later. She poisoned Gao Xiaofei with iron in her diet for a long time. After finding that it had little effect, she switched to highly toxic trivalent arsenic.

The fourth possibility is that Lou Meiying did not know that the fire was caused by Gao Xiaofei at first, but later became very angry when she found out. She used food to poison Gao Xiaofei with iron for a long time. It was just punishment, but she never thought of killing her.

The fifth possibility is that Lou Meiying did not suspect Gao Xiaofei. Chronic iron poisoning and arsenic poisoning have nothing to do with her. Grandparents and grandchildren get along very harmoniously.

The sixth possibility...

There were many possibilities. Thoughts flashed through Chen Yi's mind, and he finally found that he couldn't tell which possibility was more likely.

"What do you think caused Gao Xiaofei's death?" Chen Yi changed the subject and stopped talking about the fire.

Lou Meiying shook her head: "Half of her body is buried in the soil. What can I know? I don't know what happened to Xiaofei outside. I'm really worried about whether she has become... the same as when she was a child."

Chen Yi understood what the other party meant. Being bad in junior high school and being bad in college are two different concepts. The former is limited to the campus at best and is pointed out by the elders, while the latter will be much more serious when it develops.

But the Suicheng police have investigated these things very clearly. Gao Xiaofei has no interpersonal relationships outside of school. She is just an ordinary senior student whose parents have died. She has never had a big grudge against anyone.

Whether it's a roommate or a cousin, they only stay at the level of conflict. They say murder... it really doesn't happen.

"Do you know how Gao Xiaofei died?" Chen Yi asked.

Lou Meiying: "Didn't you say you died of poisoning?"

Chen Yi: "Do you know what the poison is?"

Lou Meiying shook her head.

Chen Yi: "Which village is your hometown from?"

Lou Meiying: "Nanshuiyang Village."

Chen Yi knew this place, not far from the city, about an hour and a half drive.

"What poisonous drugs were there in the countryside in the past?" he continued.

Lou Meiying has many treasures: "The poisonous rat is strong, the paraphylla is withered, dichlorvos, arsenic..."

When he heard about arsenic, Chen Yi captured the changes in Lou Meiying's expression and found no abnormalities.

Chen Yi: "Are these things still for sale now?"

Lou Meiying: "I don't know, maybe. Since I moved to the city, I haven't been back for a long, long time."

Chen Yi nodded slightly and started chatting: "Is it difficult to live with Gao Xiaofei alone for so many years?"

Lou Meiying sighed: "Hey, so what if it's difficult. I have to raise her well. My daughter often comes to visit me. Fortunately, Xiao Fei is very confident and has been admitted to college and is about to graduate..."

At the end of the story, Lou Meiying couldn't suppress her emotions and burst into tears.

Over in the kitchen, her daughter heard Lou Meiying's crying and walked over quickly. Seeing that her mother was losing control of her emotions, she frowned.

"Comrade police, do you want to eat at home tonight? I'll go out to buy some food."

Chen Yi knew that he was about to see off guests.

He stood up.

"No, thank you very much. Can I go to Ms. Lou's room and have a look?"

The woman's attitude became indifferent: "Whatever."

After speaking, she knelt down to comfort Lou Meiying, and gradually both women began to cry.

Chen Yi didn't care. Every case is a process that the victim's family must go through. As Zhou Yebin once said, don't empathize, just investigate the case, and regard yourself as a tool of the investigation. The suffering in the world will never be seen. The end.

At least not while everyone is still alive.

There is no suffering in the world, that is such a beautiful vision.

Arriving at Lou Meiying's room, Chen Yi took the gloves from Qin Fei. At this time, Zhuge Cong and the others had already left Gao Xiaofei's bedroom and followed them in.

The room seemed a bit crowded for seven people, so Xia Lan and Lin Chen stayed outside.

"Did you find anything?"

Chen Yi looked at the room furnishings, occasionally flipping through the items, and asked casually.

Zhuge Cong replied: "No, everything is normal."

Chen Yi didn't speak anymore, and looked and checked as he walked.

It has years, warmth, and is very neat. There are several old photos hanging on the walls, which are photos of family members.

Chen Yi walked over and saw a group photo of the Gao family directly, as well as a group photo of the entire Gao family, including Shi Yiqing's parents.

Lou Meiying has a son and a daughter. One of them died in the fire, and now only the one outside is left.

In the photo, everyone is smiling happily, but unfortunately it is now in pieces.

"Team Chen, did Lou Meiying... find anything?" Cheng Hanjun asked softly from behind.

Chen Yi shook his head: "Not yet. There is something wrong with the accuracy of Lou Meiying's memory, but her reaction is quite normal. Regarding the fire, there is a high possibility that it has something to do with Gao Xiaofei."

Several people's eyes narrowed slightly.

If the fire had something to do with Gao Xiaofei, then Lou Meiying's motive would be very sufficient.

"Do you want... to take him back for trial?" Zhuge Cong hesitated.

Chen Yi waved his hand: "Forget it, we haven't reached that point yet. Today is just a preliminary understanding. Let's go."

The inability to treat different suspects equally is commonplace for the police.

Several people walked out of the bedroom and prepared to leave. Chen Yi walked at the end and thanked Shi Yiqing's mother.

The door slowly closed, and Chen Yi turned around subconsciously. Before the door was completely closed, he had a final brief look at Shi Yiqing's mother through the narrow crack in the door.

In less than a second, the door was completely closed, but Chen Yi's eyes narrowed.

Just now, the sadness and helplessness in Shi Yiqing's mother's eyes disappeared in an instant, and was replaced by a kind of gloom.

This look was very familiar. Chen Yi had seen it on many criminals.

It was just a feeling, but his focus began to shift.

When he came downstairs, Chen Yi took out his cigarette and lit it as a habit. He looked back at the floor where Lou Meiying's house was, thoughtfully.

"Captain Chen, what's wrong?" Qin Fei said.

Chen Yi took two puffs of cigarette and said, "There seems to be something wrong with Shi Yiqing's mother."

Several people were surprised when they heard this and looked at each other. They also looked up at the floor they had just visited.

Shi Yiqing's mother?

She seems to have little to do with this case.

Zhuge Cong quickly asked: "Captain Chen, what's the problem?"

Chen Yi: "It's because of the change in his eyes."

Zhuge Cong didn't understand.

Chen Yi continued: "Gao Xiaofei's past is a weak point in the investigation, and her elders are also a weak point in the investigation. Based on the principle of doubting everything, we still need to learn more about it."

"Go back to the city bureau first, Zhuge Cong, and go get the information about Shi Yiqing's family in as much detail as possible."

Zhuge Cong: "Yes!"
