"Nothing is of any value. Li Xinxin's mother is still convinced that the murderer is Zhao Zhengyu. Ouyang Yanyan replied helplessly.

"Where did you just go?" Chen Fei asked suspiciously.

"Went to a toilet." I smiled.

Chen Fei naturally didn't believe it, but he didn't ask much.

"Ten years ago, Li Xinxin's parents should still be working in Nancheng District, right?" I asked slowly.

"Hmm!"

Chen Fei nodded and said, "Ten years ago, Li Xinxin's mother worked as a cleaner in a company, and her father was a security guard in Guangming Community. ”

"Let's go!"

"Where are you going?"

"Go to the Guangming Community."

I said and turned to leave.

Chen Fei and Ouyang Yanyan also followed.

"Detective Sun, why are we going to the Guangming Community?" Ouyang Yanyan caught up and asked with some doubts.

"Verify one thing." I smiled and didn't explain much.

Chen Fei and Ouyang Yanyan were completely confused, as if they were not from the same world as me.

Because in their eyes, everything I did didn't seem to have much to do with the case.

An hour later, we returned from Beicheng District to Nancheng District and came to Guangming Community.

"Three comrades, what do you want to know?"

When the person in charge of the community got the news, he rushed over in person.

Chen Fei didn't speak, but looked at me.

"We came here to find out who was working as a security guard here for you." I said slowly.

"I don't know what's the name?"

"Li Aihua."

"Li Aihua?"

The person in charge of the community thought about it and didn't seem to know anything about Li Aihua.

"Call the captain of the security team."

The person in charge of the community, I really can't remember, the person I was talking about, I can only call the captain of the security team.

After a while, a middle-aged man walked in.

"Lao Zhang, do you know Li Aihua?"

When the person in charge of the community saw the middle-aged man, he immediately asked.

"Li Aihua?"

The middle-aged man thought for a moment, and then said, "Come to think of it, you should be talking about Lao Li!" He seems to be called Li Aihua, the captain of the security team ten years ago, but he resigned ten years ago. ”

"You've worked with him?" I asked.

"I came for a week, and he quit and worked together for a few days." The captain of the security team replied.

"Do you remember the days you worked together, was there anything wrong with him?" I asked again.

The captain of the security team thought for a moment, and then said, "There seems to be nothing wrong. ”

"By the way, on September 8th, he was supposed to be on duty with me, but at ten o'clock in the evening, he suddenly said that something was wrong and left directly. I didn't come back until two o'clock in the morning, and the next morning, an hour before I got off work, I left early. ”

"September 8th?"

I thought about it, and soon remembered, wasn't it the day Li Xinxin was killed?

"Was there anything wrong with him when he came back?"

"If there's anything wrong, it's that when he came back, he seemed to have drunk a lot. When I returned to the duty room, I went straight to sleep. I didn't think much about it at the time, maybe he really had something, so I didn't tell him about his drinking at work. ”

"Thank you for your cooperation, I'm done."

"Team Chen, let's go!"

I just left.

Chen Fei and Ouyang Yanyan also quickly followed.

"Sun Ming, don't you suspect that Li Xinxin's father is a murderer, right?" Chen Fei asked with some confusion.

"Probably impossible, right? Li Xinxin's father, although he is patriarchal, it is impossible for him to kill his own daughter, right? And Li Xinxin has already moved out to live. Ouyang Yanyan also said.

"This case is very complicated, everyone may be the murderer, or everyone may not be the murderer, and all the suspicions need to be investigated to be clear." I shook my head.

Chen Fei nodded, and then asked, "Where are we going now?" ”

"Do you know where Zhao Zhengyu, his girlfriend from ten years ago, is now?" I thought about it and asked.

"It's not clear yet, I'll ask Li Yang to check it out immediately."

After Chen Fei finished speaking, he called Li Yang and asked him to find Zhao Zhengyu's girlfriend for ten years.

"Ten years ago, the forensic doctor who performed the autopsy on the victim is still in Haicheng?" I thought about it and asked.

"That forensic doctor's name is Yang Le, he is Han Jiu's teacher, and he is now retired, but he lives in Haicheng." Chen Fei replied.

"Go and meet the old forensic doctor, maybe there will be some gains."

I thought about it and decided to meet the old medical examiner.

Chen Fei did not refuse, and nodded.

Soon, we came to a nursing home.

After Yang Le retired, he did not live with his children, but lived alone with his wife.

However, his wife, who died a year ago, came to a nursing home and did not want to live with his children.

It's not that he has any conflicts with his children, but he doesn't want to cause trouble to his children, so he chooses to come to a nursing home.

When they came to the nursing home, they happened to meet his son Yang Chengming, a well-known surgeon in Haicheng.

"Team Chen, I haven't seen you for a long time, why did you come here today, is something happening in the nursing home?"

When Yang Chengming saw Chen Fei and the others, he asked with some doubts.

"Nothing happened to the nursing home, we just came here to meet Elder Yang." Chen Fei smiled.

"See my dad?"

"What's wrong with my dad?"

Yang Chengming couldn't help but get a little nervous.

"Brother Yang doesn't have to be nervous, Yang Lao has nothing to do, but there is a case about ten years ago, Yang Lao was a forensic doctor at that time, and he may know some things." Chen Fei hurriedly explained.

Yang Chengming breathed a sigh of relief when he heard this.

Then chatted with Chen Fei for a few words, and then left the nursing home.

"Elder Yang, I haven't seen you for a long time, how is your body?"

After Yang Chengming left, Chen Fei took me and Ouyang Yanyan to a white-haired old man.

This person is the old forensic doctor Yang Le.

At this time, Yang Le was already in a wheelchair.

"I can't die yet."

Although Yang Lao was already in a wheelchair, he still spoke very strongly, and he did not look like a frail and sickly old man.

"You came to me for a case ten years ago, right?"

Elder Yang didn't wait for us to speak, and continued.

"How does Elder Yang know?"

We were all a little surprised.
