Xu Dayuan frowned.

"Yes, this is the key question. Lao Liu, go and find out. In addition, whether the way Dr. Lu obtained the files is reasonable and whether these files are complete also needs to be verified. I will interrogate first. He Chunyang has already followed the instructions mentioned in the file.

Over several periods of time, the investigation went on."

Liu Yongxin shook his head.

"The time recorded in the file is not the real time of the crime. It is based on the time when the deceased's body was found. There are still errors in it.

The identities of the five victims we found were mainly from special occupations. They are highly mobile and it is difficult to investigate the time of disappearance. However, the time of the murder of the other six people can be estimated more accurately. I think we should mainly investigate these six time periods of Cui Guanglin.

.”

Zhou Ning pondered for a moment, raised his head and said quickly:

"In the past five years, the crime scenes have been all over the urban and rural areas around Qindao. In addition to being familiar with the terrain, we also need to have convenient transportation. I remember Cui's mother said at the banquet that Cui Guanglin just changed his car a month ago.

, can you check the car Cui Guanglin replaced?"

"The car you replaced a month ago?"

Zhou Ning nodded.

"It said it was a new car a month ago. It was a gray Teana. I don't know if the car has been picked up."

Xu Dayuan quickly dialed a phone number, and Liu Changhai quickly rushed in.

"What's wrong, leader?"

"Hurry, go to No. 1 Middle School and drag Cui Guanglin's car back. It's a silver-gray Tianlai. I think this one is easy to find. Also, when you checked him, did you find any car keys?"

"No car keys."

Zhou Ning thought for a while and looked at Da Zhao.

"Da Zhao, please follow me. The car keys are not on you, but they are in the school. Besides, I always feel that he will hide something. The school seems to be a public place, but it is not impossible to hide something."

"Okay, I understand what you mean. We'll go with the unlocker. If we can't find the key, we'll unlock the car and get it back. I'll lead someone to search carefully. Xu Da can apply for a police dog to cooperate. This thing is better than a human search.

The stuff is awesome.”

"Sure, you go ahead. Changhai knows where to go to get the police dog, so bring more people."

Liu Yongxin raised his hand and said quickly:

"I went to see Dr. Lu, one to see if the chemical composition has been studied, and the other to find out what kind of car Cui Guanglin sold before and where it was sold. I can find a better one."

Liu Changhai took Da Zhao away, and Liu Yongxin went next door.

Zhou Ning followed Xu Dayuan to the next door to the interrogation room downstairs. Before entering, Xu Dayuan warned:

"Can you control your emotions?"

"Don't worry, Xu Da. I can control my emotions. Also, let me tell you, I will let Xiaoyu go to work normally today."

Xu Dayuan was a little surprised, but after a little hesitation, he wanted to understand what the intention was.

"It's good. I'm really worried that Zhou Xiaoyu is in too deep. It's best if he can get out quickly. Let me tell Principal Bai to avoid gossip in the school."

"That's what I mean. I'd like to trouble the leader."

Xu Dayuan waved his hand, and the two of them entered the next door to the interrogation room together.

Zhou Ning watched last night's interrogation. Cui Guanglin didn't move at all, but as the fast forwarded, Zhou Ning frowned. How should I put it, the man didn't seem to move, but his expression was very different. Could he have seen it wrong?

When I asked about the progress, the people inside kept shaking their heads.

"Lieutenant He has been here for an hour and a half this time, and has been preaching policies, but these are meaningless to Cui Guanglin, he doesn't even raise his head, he just stares.

His behavior was similar to yesterday, except for eating and drinking, he just didn't respond. I just listened to your interrogation as if these things had nothing to do with him."

Xu Dayuan nodded, not surprised at all by this result.

"I know, call He Chunyang out."

The two of them went out, and He Chunyang was called over after a while. He Chunyang grabbed the mineral water on the table, drank half of the bottle, took a sip after finishing it, and stared at the single-sided glass mirror, his eyes full of anger.

"This guy is so difficult to deal with. He doesn't respond at all. His mouth is so dry when I say it, he doesn't even raise his eyelids."

"Stop complaining and take a rest. Zhou Xiaozhou and the others have received the inspection report. I'll go meet him!"

He Chunyang immediately became energetic and hurriedly came to Xu Dayuan's side. He read the report first and was beyond words to express his excitement.

"It is indeed a big fish. This guy's psychological quality is absolutely extraordinary. It seems that we need to think about his weaknesses and then conduct interrogations based on them. Even if we throw evidence in his face now, this person will not blink an eye.

After all, he is very likely to have taken eleven lives ahead of him."

Xu Dayuan smiled.

"As I thought, the fatigue tactic is useless, so let's change it. But there is no need to take out the laboratory report in a hurry. If there is no means of hitting him in one blow, the blow to him will not be too great. In this way, other

I won’t explain anything.”

Zhou Ning thought of the meeting between the two families on that day. Cui's father and Cui's mother said that after Cui Guanglin was born, they did not live in Qidong to support the family, and only returned to their hometown after retirement to reunite with Cui Guanglin.

As for Cui Guanglin, he has been living with his grandparents in Qidong. After his death on the 17th, his grandparents lived alone for many years. His parents lived with their young son, which meant that his parents did not know much about Cui Guanglin and knew about him.

Everything will most likely happen after the age of seventeen.

As for his physical development, especially the huge difference from other children of the same age, he had low self-esteem and even began to hide some evil thoughts in his heart, but he couldn't ask his grandparents about this.

"What is Zhou Xiaozhou thinking about?"

Zhou Ning raised his head. Xu Dayuan and He Chunyang were both staring at him. They had nothing to hide and said directly.

"I just thought that Cui Guanglin's parents went to support the border areas after he was born, and he grew up with his grandparents. Perhaps the lack of parents and the difference in body made his mental development unhealthy, so that after an examination in the provincial capital, he was

He couldn't find a way to vent, so he started planning all this.

If our analysis is reliable, then Cui Guanglin's weaknesses can be easily discovered. There are two of them. One is his parents, who have been separated for many years, and he longs for love more. The other is his physical disability. I saw him in the provincial capital.

In this case, he has both male and female sets of organs, although the female set is not complete.”

Xu Dayuan was stunned. When He Chunyang was about to speak, he pulled him away and stared into Zhou Ning's eyes with an expression of disbelief.

"What you mean is, talk to his parents, then let them meet, attack his psychological defense, and then find someone to give him a physical examination. No, this is not called a physical examination anymore, it should be a physical examination. The first part is easy to explain. Where can I give it to you?

Should we go to a doctor? Besides, should we go to a male doctor or a female doctor?"

"this"

He Chunyang also laughed and pulled Xu Dayuan's arm.

"The doctor will be found slowly, but the Cui family's parents can find and talk first. If their child has committed such a thing, it is not impossible to do some work and let them comfort him."

"Then get in touch!"

He Chunyang was stunned.

"I don't have the contact information of Cui's parents."

Zhou Ning took out his phone. He remembered that when they first sat down that night, his second uncle exchanged contact information with them. He called them and asked for his number. He had prepared a set of excuses but it was all in vain.

It surprised him.

"Your second uncle doesn't know about Zhou Xiaoyu, right?"

Zhou Ning shook his head.

"I haven't told my family, so I can't talk about it. When the case is announced, there will be no need to talk about it."

Xu Dayuan patted Zhou Ning on the shoulder and said nothing to comfort him. This is what everyone does, so such rhetoric is unnecessary.

At this time, He Chunyang had already dialed Cui's father's mobile phone, and was answered after one ring.

"Hello!"

"Hello, are you Cui Guanglin's father?"

"I am."

"This is the Criminal Police Brigade of Qidong Branch. You and your lover, please come here now. Let's learn about Cui Guanglin. Of course, if it is inconvenient for you, I will send someone to pick you up."

The person on the other end of the phone was obviously shocked by such words, but there was a conversation between a man and a woman.

"Who's calling? From the Interpol Team. They said they want us to go to the Interpol Team to talk about Guanglin. Are you not a liar? Liars can't let us go to the Public Security Bureau! That's right."

He Chunyang heard the conversation between the two clearly, which saved a lot of talk.

"Are you sure you don't need us to pick you up?"

"No, no, we'll be there in five minutes!"

After hanging up the phone, Zhou Ning looked at Xu Dayuan.

"For Cui Guanglin's examination, I think we can just ask Director He of the emergency department. Anyway, we can't take the person away now. It's just a visual inspection. The goal we want to achieve is not to examine, but to break his composure.

A person has been disguising himself as an ordinary teacher all year round. He is being interrogated at this moment and still cannot get rid of this identity. Only when he is excited or unable to control his emotions can he tell what he has done before. Of course, I am more suspicious of him.

, and multiple personalities.”

The little policeman next to him exclaimed.

"Multiple personalities?"

Xu Dayuan slapped the man and waved his hand towards Zhou Ning.

"What do you say, what should we do? I don't care if he has multiple personalities, as long as he can explain it seriously, but if He Shancun knew that it was you who suggested letting him come over, I'm afraid he would chase you and fight him. He really made a careless friend.

!”

Zhou Ning's body was stunned, and this was the most infamous one.
