Of course, what actually attracted Chen Bai's attention was not only the case itself, but also the relationship between the three people.

"Weren't these two people investigated after that?"

"We have investigated, how could there not be an investigation, but do you think this matter is so easy? The transcript of that time is here, you can read it yourself!"

The administrator of the archives room took out a file bag and handed it to Chen Bai. Chen Baizheng was wondering why a case should be placed in different files, and was attracted by Tan Zhenghao's transcript.

Police officer: What were you doing at one o'clock in the morning on x?

Tan Haopeng: Sleep.

Police Officer: Who can prove it?

Tan Haopeng: Officer, I live alone. Where can I prove it to you?

Police Officer: Do you know the girl across from you?

Tan Haopeng: Do you know Ruan Ling? She is a very obedient and sensible little girl. She used to say hello to us every time she saw her when she went out. I am also very sorry for what happened to her. This kind of thing happened to the little girl’s family.

What bad luck!

Police Officer: Have you seen anyone suspicious recently?

Tan Haopeng: No, everyone in this building knows each other. If you really meet someone you don’t know, you will definitely recognize them immediately.

Police Officer: You didn’t hear anything that night?

Tan Haopeng: Officer, what time was it then? I had gone to bed early and of course I didn’t hear anything.

Chen Bai read the interrogation transcript and found that although everything in the transcript was normal, this transcript was already written after Tan Haopeng moved out.

Chen Bai opened Zhao Demin's transcript and found that it only contained a few simple sentences. What Zhao Demin said the most was that he didn't know.

"Who was the previous police officer in charge of this case?"

The administrator of the archives room said nothing, but pointed to the lower right corner.

"Wu Jianguo?"

Chen Bai collected all the case information and put it in a file bag.

"I'll take these for a look first, and then I'll send them back to you."

"Chen Bai, do you think what you have done is useful?"

Chen Bai walked to the door and was suddenly stopped by the administrator of the archives room.

"This case is not just a simple disappearance case. The three people met again ten years later, and the case happened again. This is not a coincidence. There must be some connection. Finding these connections may be the key to solving this case."

When Chen Bai saw Wu Jianguo, he was taking care of the plants on the balcony.

"It's really amazing. I didn't expect you to help us solve so many major cases at such a young age."

Wu Jianguo was an old man in his sixties. He tried to straighten his back and came to Chen Bai's side.

"You came to me about the case ten years ago, right?"

Chen Bai nodded, Wu Jianguo smiled and invited Chen Bai to sit down.

"The case ten years ago was my last case. In fact, at that time I had to retreat to the second line. In my fifties, my physical strength was not as good as before, and it was impossible to work on the front line. I remember it was one morning

, a woman brought a fifteen-year-old child to the police station to report a crime. After the woman and the child explained the incident, we were all a little surprised. After that, we quickly arrived at the scene of the crime, but by that time several days had passed since the incident.

Oh my god. Fortunately, the girl didn't tidy up the room, so some evidence was preserved. I believe you have read the case information. We only investigated so much. The murderer did not leave any DNA, and the evidence left at the scene was not even

Lock in the suspect."

Having said this, Wu Jianguo also lowered his head in shame. The fact that this case has not been solved is an eternal pain in his heart.

"Officer Wu, I came here today to ask if there is anything in this case that is not included in the case file?"

Wu Jianguo raised his head and looked at Chen Bai with some confusion.

"Why do you ask that?"

"The record of this case in the case file is quite detailed, but based on the situation at the scene and Ruan Ling's confession, I think the murderer probably hid in Ruan Ling's house beforehand and drugged her after Ruan Ling came back.

There was a syringe left at the scene. What kind of drug residue was in the syringe was not stated in the case file, nor was Ruan Ling's physical examination. The footprints on the window sill were facing outward, but there were no footprints or climbing marks outside the window. If the murderer is really

The murderer came in through the window, so how come there were no traces outside? If the murderer came in through other methods, why did he leave footprints on the windowsill?"

Chen Bai's series of questions left Wu Jianguo speechless. Wu Jianguo didn't speak until Chen Bai finished speaking.

"Boy, I don't know what you are talking about. When we investigated this case, we encountered a lot of resistance. The case itself was not easy to investigate at the first time. Moreover, Ruan Ling did not cooperate at the time. A girl experienced

We can understand these things, but when I saw Ruan Ling in the hospital, I had a feeling that this girl might know who did it."

Wu Jianguo's words shocked Chen Bai, but just when Chen Bai wanted to ask more questions, Wu Jianguo stood up and picked up the watering can beside him.

"Boy, I want to ask you a question. If the evidence in your hand is not enough to arrest the criminal, and you know exactly who did it, what should you do?"

"Impossible, I will definitely find evidence and bring the criminal to justice."

Wu Jianguo smiled, but Chen Bai couldn't understand what this smile meant.

"Okay, if that's the case, I'll leave first."

Chen Bai went back with a lot of questions. When Bai Hongwei saw Chen Bai's look, he knew that there would be no results.

"Teacher Chen, I found out that Tan Haopeng went to Ruan Ling's school as a volunteer ten years ago."

Chen Bai took a look at Da Binzi's investigation results. Is it important? Chen Bai didn't know, but he couldn't question the three people now because of this case ten years ago, and he hadn't seen it yet.

Ruan Ling, if that doesn't work, you may have to go there again.

"where you go?"

Bai Hongwei saw Chen Bai walking out of the office without saying a word, and quickly caught up to ask.

"Let's go to that residential building again. I have a few more things I want to confirm."

Chen Bai did not see Ruan Ling twice, which made Chen Bai more and more curious about Ruan Ling.

"Who are you?"

Ruan Ling's door opened a crack, and Chen Bai smiled and asked Da Binzi behind him to show his ID.

"We are the police, here to investigate Zhao Xiang's disappearance!"

Although the door was only opened a crack, Chen Bai still looked inside through the crack. The room was dark with the curtains drawn. Chen Bai knew that Ruan Ling slept during the day and worked at night, so Ruan Ling should still be there at this time.

sleeping.

"I have no idea!"

Ruan Ling said that she was about to close the door, but Chen Bai quickly held it down with quick eyes and hands.

"Wait a moment. I know that I actually have no right to trouble you, but after all, Zhao Xiang is only eight years old. I think you know how important a child is to a family. I won't waste too much of your time, okay?

"

Ruan Ling was a little helpless, but finally let Chen Bai in.

"Okay, if you have any questions, just ask them quickly and leave immediately. I ordered takeout and will go to work after I finish eating."

"Okay, don't worry I won't waste too much of your time."

Chen Bai looked around, wondering why Ruan Ling's house always gave people a very depressing feeling.

"Where were you on the day Zhao Xiang disappeared?"

"Where else can I be? Of course I am sleeping at home. I write from eight o'clock in the evening to eight o'clock the next morning. Of course I am sleeping at that time."

Chen Bai nodded, and when he turned his head, he saw a pair of men's leather shoes on the shoe cabinet when he entered the door.

"Don't you live alone?"

Ruan Ling noticed that Chen Bai saw the shoes on the shoe cabinet and said with a smile.

"That's what I use to scare others. Although the people in this building are all good people, I often order takeout. It would be very troublesome if someone with intentions knows that I live alone."

Chen Bai smiled and continued to ask.

"What do you think of this kid Zhao Xiang?"

"He is very smart, but sometimes he can't calm down and can't be honest for a while. But he is indeed an obedient and sensible child, and he is nothing like his father."

Chen Bai suddenly became interested when he heard this. He put down the notebook in his hand and asked.

"Have you known Zhao Demin before?"

"I don't know, but we are neighbors and have crossed paths before. After Zhao Demin found out that I wrote novels, he once told Zhao Xiang that if you dare to do such a useless thing in the future, I will break your legs."

Ruan Ling's vicious expression surprised Chen Bai. They were neighbors ten years ago. Could it be that Ruan Ling didn't know?

"Do you usually see Zhao Xiang often?"

"Not much. Zhao Xiang had already finished school when I got up."

Chen Bai didn't ask anything else and stood up to leave.

"ah!"

Ruan Ling suddenly exclaimed. It turned out that when she stood up, she knocked over the water glass on the table and the water spilled on Da Binzi.
