Controlled experiment

Du Yusheng scratched the center of his eyebrows, feeling extremely irritable.

Putting on the shoe covers again and entering the scene of the crime, Du Yusheng began to look at the room again.

I just discovered that the furniture in the old man's room is rather old, and it doesn't fit in with the newly built community.Although Du Yusheng didn't participate in Mr. Du's business, he has heard that this community was originally the site of an abandoned factory. Later, a developer bought it, and finally it was fired. It was called a school district house, and it was worth a lot per square meter.Parents nowadays are most willing to spend money on their children, especially education.

The old man's room has two bedrooms and one living room, and the other bedrooms are probably not used very much and are all empty.The old man's clothes and daily necessities are also very few, and the clothes of the four seasons and the bedding of the four seasons do not fill a closet.Du Yusheng went over to touch the old man's mattress in a strange way. It was very thin. Even if the district heating is good, this thickness is not suitable for the old man's age.

Du Yusheng frowned, and scolded the old man's shit in his heart.

There is a mobile phone of the old man on the desk, it is not a smart phone, it is not even a touch screen, there is not even a brand on the mobile phone, it looks like a counterfeit product.The red and green buttons for talking have been peeled off, exposing the cheap soft plastic underneath.

It seems that the button is not very easy to use, Du Yusheng pressed it for a long time before finding out the old man's call records.

In the past two months, the old man dialed the three numbers dozens of times, but none of them were connected.

Du Yusheng frowned and put the phone in the evidence bag and threw it to Xiaobai.

Said: "Check these three numbers."

Xiaobai nodded, looked at the mobile phone in his hand for a moment, and said, "Is there still a phone like this?"

"Old people." Du Yusheng explained: "We don't know how to use people like us."

Xiaobai sighed and said, "The old man has a special mobile phone, and the keyboard characters are very large. Don't you think the keyboard characters on this phone are so small that the elderly can see clearly?"

Du Yusheng took a closer look, the characters were small enough.

"Xiaobai." Du Yusheng opened the window and pointed to the small fountain downstairs: "Look downstairs, the furniture in this room is almost the same age as the deceased. The deceased is very frugal, so why are they so expensive?" This is a house in the school district."

At first, Xiaobai wanted to talk about housing in the school district and picking up his grandson.Or it was bought by the children.

After thinking about it later, the family didn't visit the old man once for several months, so where would the grandson pick him up?

Looking at Du Yusheng's eyes, Xiaobai thought to himself, well, I'd better go out and ask the neighbors by myself.

Du Yusheng stood by and watched the old man's body being carried away, feeling a little sour in his heart.

The children who have been raised for a lifetime, in the end, the children don't know the moment they die.

The milk delivery boy who reported the case was still taking notes on the scene, and Du Yusheng called him to him.

The milk delivery boy is a middle-aged man, not tall, with a slightly hunched back, wearing the vest of their milk delivery company, and a cap with a logo on his head. His green milk delivery truck is parked downstairs, and Du Yusheng came in. I saw it in time.

The little brother should be running outside often, his skin is very rough, but he doesn't look like the age on his ID card.

"What's your relationship with the deceased?" Du Yusheng asked.

"I deliver milk in their community, every morning between eight and nine." The little brother is not stage frightened, and he is not frightened by the death.

Du Yusheng looked at his watch and said, "It's already afternoon from eight to nine o'clock, and you found out in the morning that you only reported the crime in the afternoon?"

The little brother shook his head, and showed Du Yusheng the milk delivery registration form in his hand.

"I have something to do this morning. I wanted to deliver it to my colleagues, but they couldn't adjust their shifts, so I can only deliver it at this time. A few customers were dissatisfied just now. Alas, I don't know if I will complain. I."

The little brother frowned slightly when he said this, and kept looking at the comments below with the mobile phone in his hand, for fear that someone ordered a bad order.

It's not easy to do this job, Du Yusheng understands.

The words were also relaxed.

"I heard that you thought there was something wrong when you saw that the baby bottle in the box outside hadn't been touched for three days." Du Yusheng smiled and said, "Didn't you feel something was wrong on the first day?"

The little brother shook his head and said: "It's not the baby bottle that has been stored for three days, it's my milk that has been stored for three days. Mr. Qian has not touched it. Mr. Qian talked to me in those few days. He said that he had saved some retirement money. In the past few days, I want to take my children to go out and travel while I can still move around. I thought Qian always went out to travel and never came back. I came to see the milk delivery every day. The milk in it has never been gone. I moved it, and then I felt something was wrong, so I asked Mr. Qian’s neighbors, and they said that no one saw Mr. Qian going on a trip, so I thought something was wrong.”

The more Du Yusheng listened, the more hesitant he became.

It's good that the children invite the old people out to play, the old people are rushing to invite the children out.

Speaking of this, Du Yusheng also wanted to know the owners of the old man's mobile phone, and they should be the three unfilial sons of the old man.

Du Yusheng could guess what the old man was thinking, and wanted to see his children by spending money to ask them to go out to play, but he didn't realize it. He called for three months, but no one answered.

Satire.

What a fucking irony.

Du Yusheng took two puffs of his cigarette.

During the smoking room, Xiao Bai ran back from outside.

"Ask clearly?"

Xiaobai nodded, but the expression on his face was not very good.

"Brother Yu, you know what the neighbor told me." Xiaobai said, "The neighbor said that Mr. Qian has lived here for seven or eight years. He used to live in a retirement home. It was remote, and his children rarely went there. Looking at him, he seldom made phone calls. Qian always thought it was because he lived in a remote place and it was inconvenient for his children to come. A few children, it is convenient for their children to go to school. It is somewhat effective. Although the few children come here less often, they come once a month. As a result, after the house is transferred to those children, they almost never come again But, what do you mean by this?"

"What did Mr. Qian do before he retired?"

Xiaobai said: "The neighbor said he is an intellectual, he seems to be a teacher. We really have to wait for the family members to come over."

The elderly spend most of their youth teaching and educating people, and the world is full of peaches and plums.Unexpectedly, these white-eyed wolves were raised at home.From the books placed in Mr. Qian's home, it can be seen that he is a person with a high level of ideological awareness. Even if his children are not filial, he will not be too resentful, Du Yusheng thought.

After a long time, Du Yusheng sighed, and said, "Actually, it doesn't matter how far the distance is. Children have this kind of heart, even if they are in the north and south, they are worried about it."

Du Yusheng took a few steps outside and shook his head.

Pointing to this room, said: "They don't cherish it."

Du Yusheng also likes to quarrel with Mr. Du, and when Mr. Du doesn't like it, he also scolds a few words. Now that I think about it, this is an indispensable part of father and son's life. Even if they quarrel, it feels warm to think about it. It won't happen to me anymore.

There is still a place for parents in life, and there is only a way back for parents to go to life.

Old Qian's sons and daughters probably will never realize this.Du Yusheng vomited a smoke ring, wanting to scold the three white-eyed wolves.

When Xiaobai came out, he saw Du Yusheng smoking a cigarette, and took two steps over there.

Advised: "Brother Yu, what's the matter today, take two less cigarettes."

Du Yusheng waved his hand and said: "I'm fine, you go to get the surveillance, record a statement, and ask the community security if there are any suspicious people. The surveillance in this community should be quite complete. Give the body directly to Qin Yan. He should know what to do. My intuition now is that Chen Xin and him did it alone. But I didn't expect to contact. As soon as there is news, let me know, and I will be there 24 hours a day."

24 hours in.

Xiaobai was stunned, Du Yusheng never had this awareness in Xiaobai's eyes.

He was surprised.

"Sure, if it was really done four nights ago, I guess it will be found through the monitoring and investigation at night. If it's like what you said, Chen Xin's case can be solved easily. But I guess I still have to wait for Brother Qin's report."

Du Yusheng nodded.

"Oh, by the way, Gu Qingyu lied and brought him back to the bureau for interrogation, and where is Chen Xin?"

Xiaobai clicked his tongue and said: "Tomorrow morning, no matter what happens to his wife, we have to go in and take a look. First, we will take care of their family's emotions. His wife will make progress, and if we continue to stop him, I will feel that his wife killed Chen Xin. For The point of compensation has been biting the hospital, so what, is this a rich businessman?"

Du Yusheng shook his head helplessly.

I thought that with Chen Xin's current economic strength, he was no longer a rich businessman.

"Maybe it's time to join the case, then I'll go out first, and you finish it."

Du Yusheng raised his chin and pointed at the scene of the crime.

Xiaobai readily agreed this time, and nodded without saying anything.

Coming out of the community, Du Yusheng was so stuffy that he couldn't suppress the bitterness in his heart even with a single cigarette.

He feels oppressed.

It was still bright when we came in, and it didn't take long, it was already dark, Du Yusheng looked at his watch subconsciously, it was already 08:30 in the evening.

I don't know if it's because of Qian Lao's death that Du Yusheng felt empathy for him, and the emotional pressure on his chest could not be dissipated for a long time.

Turn on the phone and look through the address book.

Du Yusheng had some drinking and meat friends, and they were all playboys. After he entered the police station, he didn't have many contacts.

At the moment, Du Yusheng didn't want to find someone out for a drink, he just wanted to find someone quietly to accompany him and have an ordinary meal.

Du Yusheng found out Li Yao's cell phone number.

Dial his number.
