That afternoon, Lu Lingtian took advantage of Qu Yunyi's nap to take Zhao Qin out, and specially told Si Yuan to let Yunyi stay in the company and wait for him to come back.

Si Yuan didn't know what they were going out for, so she did as she was told.

Along the way, Lu Lingtian was thinking about the whole thing, thinking of what Cheng Zhenfeng said, he was even more sure that the whole thing might involve a bit of a big picture, and even Cheng Zhenfeng was afraid of how much power did he have?

A big man, why should he go against a small security guard like Qu Chengfeng?

All this makes some sense, it seems that he can only find the source in order to answer the doubts in his heart.

This person's name is Deng Rui, he was in charge of Qu Chengfeng's case at the beginning, retired half a year ago, lived in an old community, and now lives a leisurely life.

"Deng Rui has a son who works in a financial company and is an ordinary employee, and the family is quite passable. He is now retired and takes care of his grandchildren every day, and there is nothing suspicious about his life. ”

"What about the property, is there anything suspicious?"

"I didn't find this, Deng Rui also lived in this community after he retired, usually lived a simple life, saved money, and subsidized his son and daughter-in-law, the son is also very filial, and the family is happy. ”

It doesn't sound flawed at all. When Zhao Qin checked here, he also felt that he was investigating in the wrong direction.

"That's right, let's go see this Deng Rui first. ”

In such a hot weather, in the afternoon, there are no grandfathers playing chess in the community. Occasionally, in the cool corridor, a few elderly people gather together to play mahjong to pass the time. Lu Lingtian's car parked in the community is particularly eye-catching, and those who don't know it can guess that this car is not cheap.

As soon as they appeared, they quickly attracted everyone's attention.

Watching them go to Lao Deng's house, everyone became curious. Usually, Lao Deng's family is ordinary, and he has never seen such a noble person appear.

Isn't it getting into some kind of trouble?

"Don't you see people carrying fresh fruit baskets and wine? Maybe some friend's child came to visit, don't always think badly. ”

Everyone whispered, and they didn't dare to let them hear it.

Zhao Qin knocked on Deng Rui's door with something, and after a while, Deng Rui was busy opening the door.

"Who?" he wore reading glasses, no different from an ordinary old man on the street, and he didn't see the momentum of a police officer at all. If Zhao Qin wasn't sure, just seeing his appearance, he would definitely think that he had made a mistake.

"Excuse me, is this Deng Rui, Mr. Deng's home?"

"I'm Deng Rui, who are you?"

It's a police officer, but Deng Rui is still a little vigilant. Looking at the two of them in suits and leather shoes, Deng Rui did not immediately open the door for them, and looked at them vigilantly.

"I hope you don't mind. We are here today because there are some things I would like to ask you about. About a case you were responsible for eight years ago. I don't know, it's inconvenient for you to let us in and sit down and talk. ”

"Eight years ago, what kind of case did you have? If you want to know the situation, why didn't you go to the bureau to ask, and you came to me?"

"You're a policeman yourself, and you're afraid that we're bad guys, and we're really here to visit!" Zhao Qin said, handing out his business card.

"We always have something to ask you about the situation, I hope you can understand. ”

He carefully compared it and made sure it was him, but he still had no intention of opening the door.

Seeing this, Lu Lingtian said a name.

"I don't know, do you remember that eight years ago, on that rainy night, Qu Chengfeng jumped from the top floor of the Shuangfeng Building?"

At the mention of this name, Deng Rui's hand shook obviously.

"Qu Chengfeng?" he looked back and forth at the two of them, "Who are you?"

"I am his family, and I came here to learn about him who committed suicide by jumping off the building. Now, can you open the door and let us in?"

Deng Rui thought about it, and then opened the door and let them in.

The room was neat and clean, Deng Rui politely poured them tea and sat down opposite them.

"It's been so long, why are you still asking about these things. If you want to know the specific situation, shouldn't you go to the archives?"

"You are the person in charge, you should know that there was very little information about Qu Chengfeng's suicide case at that time, and there are even fewer that can be verified now. I had no choice but to find your address and came to the door to find out the specific situation at that time. You were there, weren't you?"

"The case is closed, why are you young people entangled in this matter now. In the past, it is better to let it pass. ”

"If there are no problems, we want to turn the page on that. But we suddenly realized that there was something wrong with the situation at that time. If it's just an ordinary case, presumably, you won't hear the words Qu Chengfeng, and remember what happened. ”

Deng Rui was stunned, and then realized that his reaction was a little abnormal.

"We're police officers, and it's normal to remember these things. It rained too much that night, so I remember. Any questions?"

Lu Lingtian nodded, even if this is a far-fetched explanation!

"My grandson is still taking a nap in the house, if you have anything to ask, just ask! Actually, I don't know much, and as recorded in the file, I'm afraid it will disappoint you. ”

"Whether we are disappointed or not, we have the final say. All you need to do is answer my questions truthfully. At that time, Qu Chengfeng was judged to have committed suicide by falling from a building, is the evidence to support suicide sufficient?"

"Of course! There was no one else in Shuangfeng Mansion at that time, and we also found his autographed suicide note on Qu Chengfeng's body, and everything was logical. ”

Deng Rui said it as a matter of course, and Lu Lingtian asked again: "You are also a father, if you are Qu Chengfeng, you finally raised your daughter to the age of sixteen, and there is no financial pressure, do you think he has any reason to leave his favorite daughter and choose to commit suicide by jumping off the building?"

Deng Rui was stunned, this question also stayed in his heart at the beginning.

But......

"I'm not him, how can I know what he thinks, everyone who commits suicide is because they can't think about it for a while. Maybe, he just felt that life was too hard, and he didn't think about it at the time, so he chose to commit suicide. I think it's normal. How is it possible for a living person to understand the thoughts of a person who commits suicide?"

"Would you abandon your lovely child? Qu Chengfeng loves his daughter very much and treats her as his life. From his point of view, if you think about it, he would kill himself? Don't you think it's suspicious?"
