How did you, a gangster, end up in the police force?

Chen Youkai's eyes flashed with surprise, and then quickly turned into a state of rage, "I, a psychiatric expert, am so angry, which shows that you police are doing nothing and acting blindly."

Ye Lin raised the corners of his mouth slightly and smiled, "Okay, since the old man is so angry, let's talk about it next time."

After saying that, he left without looking back, leaving everyone present dumbfounded. Didn’t he want to see the old man and ask him questions? Why did he come, say a few words, and then leave?

Then why were you so persistent just now?

The young auxiliary police officer didn't react at once, and when Ye Lin was about to walk out, he hurried over to catch up.

The door behind him slammed shut, reflecting the owner's dissatisfaction.

The young auxiliary police officer was a little confused. He looked at Ye Lin and asked, "Captain Ye, didn't you just say you wanted to ask the old man? Why didn't you ask now that the man is here?"

"No need to ask. You won't be able to get anything out of him. Let's just investigate. Go to the property management and check the surveillance. I want to know if he left the community on the night of the incident." Ye Lin said with a hint of fear in his eyes. This old man might not be simple.

"Captain Ye, is there something wrong with him?"

"Well, although there is no evidence, I think he is a bit strange. I came twice, and both times he behaved very irritably, but he is a psychologist and shouldn't be like this. I think he is acting." Ye Lin said.

"Also, when he was angry just now, he patted Chen Yiming gently, probably to tell him that he was fine."

The young auxiliary police officer scratched his head. Why are there so many movements? Why didn't I see them?

But since Ye Lin said he wanted to investigate, then let’s investigate.

Chen Yue's family is well off. This community is a new one, so the facilities are relatively new and there are more surveillance cameras than in those old communities.

Ye Lin quickly found the surveillance footage from that day and brought it all back to the bureau. He wanted to watch it slowly.

Chen Yue's home.

After Ye Lin and the others left, the house became quiet again.

His wife Wang Shaoli went to help their daughter with homework. Chen Yiming sat alone in the study. After thinking for a while, he decided to go talk to his father.

Chen Youkai sat calmly on the small balcony of his room, looking at the night sky.

"Dad, are you feeling better?" Chen Yiming asked in a low voice. His father's heart was not very good, and he would feel very uncomfortable if he was angry.

"I'm not really angry, I'm just pretending." Chen Youkai said calmly.

Chen Yiming looked at his father in surprise, "You patted me just now to say that you were pretending?"

Chen Youkai turned around and looked at his son. He was in his forties and had been on the operating table every day since graduating from college. There were many things he had never experienced.

"If we don't pretend, are we going to let these two policemen stay here to influence Yueyue?" Chen Youkai sighed. His son didn't understand, and he couldn't do anything about it.

"Well, Dad, the police said they wanted to talk to you. Did you go out that night? I remember Lily told me that you came back quite late." Chen Yiming mustered up the courage to ask. He had never doubted his father, but after reading so much, he always felt that the police would not wrongly accuse anyone. Suddenly, his belief was not so firm.

"Do you think I would kidnap Mao Xiaolin?" Chen Youkai chuckled as he looked at his son.

"No, I..." Chen Yiming didn't know how to explain.

Chen Youkai suddenly wondered if he had been too strict with his son back then, which was why he was so timid now.

He sighed softly and gave his son an affirmative look, "I just ran into a friend that day and chatted for a while, don't worry."

"Oh, that's good, that's good." Chen Yiming let out a sigh of relief, turned around and left. He did not notice the disappointment in his father's eyes.

......

Criminal Investigation Brigade.

Ye Lin stayed up all night watching the surveillance video. It should be said that everyone was doing the same thing. In this era, surveillance is sometimes more useful than anything else.

Chen Youkai was in high spirits, and Ye Lin quickly found him on the surveillance camera. A little after 6 o'clock in the evening, he appeared downstairs, chatted with a few elderly men and women for a while, then got up and walked towards the gate of the community.

Ten minutes later, Ye Lin saw Chen Youkai's figure on the surveillance camera at the community gate. He walked straight out of the gate and disappeared into the night.

In order to find out the time when he would return home, Ye Lin squatted in front of the computer and smoked a pack of cigarettes until his lungs were about to burn. Only at 11:10 pm did he see Chen Youkai returning to the community.

He left the community at 6:40 in the evening and returned at 11:10, a total of more than four hours, which completely included the time of Mao Xiaolin's case. Judging from the time, the old man definitely had time to commit the crime.

Moreover, he is a psychiatrist, so he is more likely to implement psychological castration than ordinary people.

On October 10, the seventh day after the incident, a ray of light shone into the Criminal Investigation Brigade.

One by one, the ghost-like people raised their heads from the table and went back to work.

Yu Haifeng called everyone to a regular meeting early in the morning.

First, there was the man who was knocking his legs. Lao Zhao and the others found him on the surveillance camera, right next to the trash can outside the community. Since his knocking of his legs was so obvious, they quickly locked onto him.

But this person was wearing a hood, so no frontal photo was taken at the time.

However, at the next few intersections, because it was too hot, he took off his hood and revealed his face.

A photo was projected on the screen. It wasn't very clear, but you could still tell that the person was not young at all, a middle-aged man.

"We went to the police station for comparison and found out that this man is He Zhifeng, He Xue's father." Old Zhao stood up and said excitedly.

"It's actually him." Ye Lin exclaimed. He heard He Xue talk about his father last time, but had never seen him. He didn't expect to confirm his identity the first time he met him.

"Captain Yu, I also found something here." After Lao Zhao finished speaking, Ye Lin stood up.

He took out the surveillance video of Chen Youkai. "This is Chen Yue's grandfather, Chen Youkai. He was a psychiatrist before retirement. He left the community at around 6pm that night and returned at around 11pm. He had enough time to commit the crime. Plus his background as a psychiatrist, I think he has a lot to do with this case."

Everyone was a little surprised when they heard the first person was He Xue's father. When Ye Lin revealed the second person was Chen Yue's grandfather, everyone was even more shocked.

"Two old people? Was it two old people who did it?" Wang Longxin found it a little hard to imagine.

He Xue's father is still younger, around 60; Chen Yue's grandfather is 70 years old. The two of them are over 130 years old in total. How could they kidnap people?

"I feel they are not free from responsibility," Ye Lin emphasized.

Yu Haifeng frowned, looking troubled. It was the tradition of Daxia to respect the old and love the young. But now, the old had kidnapped the young.
