Xu Dayuan frowned.

"Yes, this is the key question, Lao Liu, you go and inquire, in addition, whether Dr. Lu's way to get the files is reasonable, and whether these files are complete, also needs to be verified, I will interrogate first, He Chunyang has already investigated according to the several time periods mentioned in the file."

Liu Yongxin shook his head.

"The time recorded in the file is not the real eucalyptus time, it is all extrapolated backwards from the time when the deceased's body was found, and there are still errors in this.

We found that the five victims, whose identities are mainly special occupations, are highly mobile, and it is difficult to investigate the time of disappearance, but the time of the other six people can be estimated more accurately, and I think we should mainly investigate Cui Guanglin's six time periods. ”

Zhou Ning groaned slightly, raised his head and said quickly:

"In five years, the eucalyptus places are all over the border between urban and rural areas around Qindao, in addition to being familiar with the terrain, but also having convenient means of transportation, I remember Cui's mother said at the banquet that Cui Guanglin had just changed the car a month ago, can you check the car that Cui Guanglin replaced?"

"The car you changed a month ago?"

Zhou Ning nodded.

"I said it was a new car a month ago, and it was replaced by a gray one, and I don't know if the car was brought back."

Xu Dayuan hurriedly dialed a phone call, and after a while, Liu Changhai rushed in.

"What's wrong with the leader?"

"Hurry up, go to No. 1 Middle School, tow Cui Guanglin's car back, silver-gray, I think this is easy to find, and when you check him, do you find that there are car keys?"

"No car keys."

Zhou Ning thought about it and looked at Da Zhao.

"Da Zhao, you go along, the car key is not on me, it's in the school, and I always feel that he will hide something, the school seems to be a public place, but it is not impossible to hide some things."

"Okay, I understand what you mean, let's take the unlocker, we can't find the key, the car will be unlocked and get it back, I'll take someone to search carefully, Xu Da will apply for a police dog to cooperate, this thing is better than people looking for things."

"Cheng, you guys go, Changhai knows where to get the police dog, bring more people."

Liu Yongxin raised his hand and hurriedly said:

"I'm going to find Dr. Lu, one is to see if the chemical composition has been studied, and the other is to find out what kind of car Cui Guanglin sold before, where it was sold, and 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 of the interrogation room downstairs, and before he entered, Xu Dayuan admonished:

"Can you control your emotions?"

"Xu Da rest assured, I can control my emotions, and let me tell you, I let Xiaoyu go to work normally today."

Xu Dayuan was a little surprised, but after a little hesitation, he figured out what his intention was.

"It's good, I'm really worried that Zhou Xiaoyu is too deep, it's best to get out quickly, Principal Bai will tell me there, so as not to gossip in the school."

"That's what I mean, trouble the leader."

Xu Dayuan waved his hand, and the two entered the interrogation room together.

Zhou Ning followed and watched last night's interrogation, Cui Guanglin didn't move at all, but as he fast-forwarded, Zhou Ning frowned, how to say it, this person didn't seem to move, but his expression was very different, could he have seen it wrong?

After asking about the progress, the people inside kept shaking their heads.

"Squadron He has been in for an hour and a half this time, and he has been preaching policies, but these are meaningless to Cui Guanglin, he doesn't raise his head, he doesn't squint like that.

It's similar to yesterday's performance, except for eating and drinking, but there is no response, and I listen to your interrogation, as if these things have nothing to do with him. ”

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

"Got it, call He Chunyang out."

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

"This product is too difficult to handle, the whole one didn't respond, I said that my mouth was dry, and people didn't lift their eyelids."

"Don't complain, you take a rest, Zhou Xiaozhou and they got the inspection report, I'll meet him!"

He Chunyang suddenly came to his senses, rushed to Xu Dayuan's side, read the report first, and was indescribably excited.

"Sure enough, it's a big fish, the psychological quality of this thing is definitely not ordinary, it seems that we have to think about his weaknesses, and then interrogate him according to his weaknesses, we are now throwing evidence in his face, this person will not blink, after all, he is very likely to carry eleven lives in front of him."

Xu Dayuan smiled.

"As I thought, fatigue tactics are useless, so let's change it, but this test report doesn't need to be taken out in a hurry, without the means of hitting him with one hit, the blow to him won't be too big, so other things won't be explained."

Zhou Ning thought of the meeting between the two families that day, Cui's father and Cui's mother said that after they gave birth to Cui Guanglin, they did not live in Qidong to support the border, and only returned to their hometown after retirement, just such an only son.

And Cui Guanglin has been living with his grandparents in Qidong, after his grandparents died at seventeen, they lived alone for many years, and his parents lived with their youngest son, that is, his parents did not know much about Cui Guanglin, and they knew everything about him, and it was likely to be after the age of seventeen.

As for the development of the body, especially the huge difference with children of the same age, he has low self-esteem and even began to hide some thoughts in his heart, but this can't ask his grandparents.

"What does Zhou Xiaozhou think?"

Zhou Ning raised his head, Xu Dayuan and He Chunyang were staring at him, and there was nothing to hide, so he said directly.

"I just thought that Cui Guanglin's parents gave birth to him and went to the branch, he grew up with his grandparents, maybe the lack of parents, as well as the difference in his body, made his psychological development unhealthy, so that after the examination in the provincial capital, he couldn't find a way to vent, so he began to plan all this.

If our analysis is reliable, then Cui Guanglin's weakness, it is easy to find that there are two of them, one is the parents, perennial separation, he is more eager for love, and the other is the mutilation of the body, I saw his case in the provincial capital, he has two sets of organs for men and women, although the female set is not completely ......"

Xu Dayuan was stunned, and when he saw He Chunyang about to speak, he pulled the person away and stared at Zhou Ning's eyes with an expression of disbelief.

"What do you mean, talk to his parents, then let them meet, attack his psychological defenses, and then find someone to give him a physical examination, no, this is not called a physical examination, it should be a physical examination, the front is good, where can I find a doctor for you? Besides, looking for a male doctor or a female doctor? ”

"This ......"

He Chunyang also laughed, dragging Xu Dayuan's arm.

"The doctor is looking for it slowly, but the Cui family's parents can find and talk about it first, their children have committed such a thing, do some work, and let them comfort it."

"Then go get in touch!"

He Chunyang was stunned.

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

Zhou Ning took out the phone, he remembered that when he first sat down that night, the second uncle exchanged contact information with them, dialed the phone, and asked the second uncle for the number.

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

Zhou Ning shook his head.

"I didn't tell my family, I can't talk about this, and when the eucalyptus is announced, I naturally don't need to say it."

Xu Dayuan patted Zhou Ning on the shoulder, he didn't say anything comforting, everyone is doing this, there is no need for such a statement.

At this time, He Chunyang had already dialed Cui's father's mobile phone, and it was connected as soon as it rang.

"Hello!"

"Hello, is it Cui Guanglin's father?"

"I am."

"This is the Criminal Police Brigade of the Qidong Branch, you and your lover come over now, let's learn about Cui Guanglin's related matters, of course, if it's inconvenient for you, I'll send someone to pick you up."

On the other end of the phone, apparently taken aback by such words, there was a conversation between a man and a woman.

"Who's calling? The criminal police team said that they wanted us to go to the criminal police team to talk about Guanglin. Not a liar, right? Scammers can't let us go to the Public Security Bureau! That's right, too. ”

He Chunyang listened to the conversation between the two very clearly, which was a lot of waste.

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

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

Hanging up the phone, Zhou Ning looked at Xu Dayuan.

"Cui Guanglin's examination, I think it's okay to find Director He of the emergency department, anyway, we can't take people away now, it's just an appearance inspection, and the goal we want to achieve is not to check, but to break his calmness.

A person disguises himself as an ordinary teacher all the year round, he is being interrogated at this moment, and he still can't get rid of this identity, only when he is excited, or can't control his emotions, can he tell what he committed before, of course, I doubt him more, and he has multiple personalities. ”

The little policeman next to him exclaimed.

"Multiple personalities?"

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

"What do you say, what should we do, I don't care if he has multiple personalities, just explain it seriously, but if He Shancun knew that it was you who proposed to let him come over, I'm afraid he would chase you and fight, it's really careless in making friends!"

Zhou Ning's figure was stunned, and his infamy was not bad.
