Interrogation room.

Xu Dan was still struggling, as if he wanted to break free from the shackles of the handcuffs, looking at her so manic, Xu Dayuan frowned slightly, turned around and walked out of the interrogation room without speaking, and this action made Zhang Sannian stunned.

With the sound of the door opening, Xu Dayuan had already come to the observation room next door and walked straight towards Zhou Ning.

"Xu Dan doesn't look right, in the relevant examinations, does this person have mental illness, or does this person take drugs? Why do you seem so restless?"

Zhou Ning also discovered this and stared at the interrogation room, this is not something he can evaluate.

"I suggest that Xu Dan be given a physical examination first, as well as a psychiatric evaluation, if she is pretending to be 'insane, this is obviously to evade criminal responsibility, everything is normal after ten years of murder, and the police find evidence that she is insane, so step on it?"

As he was speaking, Xu Dan rolled the whites of his eyes, trembling all over, his back was straight, his body was arched, and his arms were grasped and straightened, looking like a sheep had a seizure.

Xu Dayuan hurriedly rushed back to the interrogation room and asked Xu Dan to get Xu Dan off the interrogation chair, but the handcuffs were still with him, and Zhang Sannian had already dialed the 120 emergency number.

Zhou Ning dialed He Shancun's mobile phone.

"What are you doing?"

"Urgent, there is a suspect, he was very crazy when he came back from the arrest, I don't know if it was real or pretended, now his body is straight and he rolls his eyes, his spine arches, and his whole body is convulsed, is this a seizure?"

"The description can't be judged, but it's still beneficial for you to send it to the hospital, find a psychiatrist for consultation, generally check an electroencephalogram to know, and record the seizure, I'll find someone here to show you."

Zhou Ning hung up the phone, Da Zhao had already heard it, started recording, and turned on the law enforcement recorder, which was then sent to He Shancun.

The sound of an ambulance outside was already heard here, a criminal police officer came in with 120 emergency personnel, Xu Dan was put in the car and transported out, Xu Dayuan's face was pale, and he came to Zhou Ning's side.

"If Xu Dan is mentally ill, he will escape punishment."

Zhou Ning patted Xu Dayuan's arm and gave him a comforting smile.

"Don't worry, leader, I asked Lao Xu just now, when I send it to the hospital, let the psychiatric department consult, just do an electroencephalogram if it's true or not, and the parents of the Xu family can bring it to understand the situation first."

After all, according to the Chen family, Chen Ningyu may have been killed on August 12, 2002, drugging, killing, dismembering the body, hiding, and cleaning up the scene, this series of operations will take at least five or six hours for Xu Dan, who is only 18 years old and still thin.

Is there no one at Xu Dan's house? Although Xu Qing is studying in a different place and has a summer vacation, the father of the Xu family is a village doctor, and this is almost a year-round occupation in the village, and he is not at home?

And Mother Xu, August is the summer vacation, isn't she there? Of course, there are also the old men of the Xu family, we can investigate these first, right?"

Xu Dayuan nodded, exhaled, and hugged Zhou Ning's shoulder, and his anxious mood was also relieved.

"I was impatient, completely disturbed by Xu Dan's illness, let Zhu Xingxing and Liu Yufei follow me to the hospital, keep an eye on the situation over there, you follow me to see the Xu family's parents."

Zhou Ning nodded, since he came to Rudong City these days, every day has been high-intensity work, physical and mental strength, and his nerves are so tense, he understands Xu Dayuan's impatience very well. ….

"Okay, I'll listen with you, but the Tao team is injured, follow Liu Yufei and the others, let's go to the hospital for stitches together."

Xu Dayuan hurriedly went to make arrangements, Xiao Zeng Xiaobai led the people from Rudong City to bring the Xu family's parents over, and Tao Zhenshan went to the hospital with Liu Yufei and Zhu Xingxing.

Zhou Ning saw the lively Xiaoqu at the door and waved his hand at him.

"What's wrong, Director Zhou?"

"Check it, Xu Dan was admitted to the tax bureau at that time, or was assigned after graduation, and she had an annual physical examination report after working, I want to know all the information, especially the past medical history, as well as the physical examination report when the public examination, mental history, epilepsy history, night wandering syndrome, and hysteria history."

Xiaoqu nodded, walked quickly into the observation room, and started holding the computer

Crackling operation, after a while, the computer showed some investigation results, and he quickly turned the screen and showed it to Zhou Ning.

"Xu Dan was admitted to the tax system in 2006, and all the physical examinations were passed, and in the content of the public examination, there are no mental illnesses you just mentioned, and there is no family history, and the only unqualified physical examination item is sediment-like gallstones."

Seeing this, Zhou Ning breathed a sigh of relief, but Xu Dan's performance just now was too much like a seizure, maybe she had seen a real epilepsy patient have a seizure, otherwise she would not be able to know these details.

Da Zhao held a law enforcement recorder, constantly adjusting the speed, watching with relish, Zhou Ning glanced at it, he didn't notice it, just when Zhou Ning was about to speak, Da Zhao stared at his small eyes and opened his mouth wide.

"I'll go, is this Xu Dan so fierce?"

Zhou Ning was stunned.

"What's wrong?"

Da Zhao hurriedly handed the law enforcement recorder to Xiaoqu, signaling him to export it and play it on the computer, Da Zhao pointed out the location that needed to be played, and then said:

"This is Xiao Zeng's law enforcement recorder, I just tore off the clip in the back, and I changed it, I accidentally saw the picture of them arresting Xu Dan, this Xu Dan came out of the hall of the tax bureau, talked directly on the phone, and then got into the car and began to ram the police frantically.

Look here, when she finally rushed towards the gate, she was hit and stopped by the Tao team's car, and if people don't get out of the car, Sister Liu smashed the glass, and she had to reverse and hit people, which is simply a crazy behavior."

Zhou Ning stared, frowning.

"Xiaoqu, check out, who called Xu Dan just now, obviously Xu Dan knew that the police were going to arrest her outside, so he drove away frantically.

No! It's not a frenzy to escape, it's a 'history of mental illness' for yourself, and the person who wants to escape the law and call to report the news may be an insider."

Da Zhao blinked and understood what Zhou Ning meant.

"Zhou Xiaozhou, what you mean is that someone reported to Xu Dan that we were going to arrest her, so let her leave quickly, or pretend to be mentally ill in public, so that he must be sure to manipulate the results of the consultation, and with this diagnosis, he is an incapacitated person."

Zhou Ning nodded, at this time Xiaoqu had already arrived at the information, and when he saw this number, Xiaoqu hurried to do it.

"This is a landline number, I checked it, this number belongs to the Rudong City Public Security Bureau, don't worry, I'll see, which office it is." ….

Da Zhao waved his hand.

"Don't bother to check, I'll call Captain Zhang, I think he should know, and even if we find out, we need to find out who made the call."

Zhou Ning nodded, Da Zhao ran out in a hurry, Zhou Ning took out the police report and found Xu Dan's information, her husband's name is Li Kelin, and it is written in the column of the work unit, which is the Water Conservancy Bureau.

According to his guess, the closest person around Xu Dan, that is, her husband, since he can know the news of the police and manipulate the diagnosis results, this person is either working in the public security bureau or working in a hospital, but it is neither.

Zhou Ning, who was deep in thought, didn't wait for him to think about it, Zhang Sannian and Xu Dayuan had already walked over quickly.

Zhou Ning told the two of them what he had just discovered, showed the number, and also said his own judgment, and even showed the results of the police communication to the two.

Zhang Sansan's face was even more embarrassed, and he entered this number on his mobile phone, and the remarks of the Immigration Department were displayed on it.

"Do you need me to check the surveillance?"

Xiaoqu whispered.

"Except for the interrogation room, hall, and corridor, there is no monitoring in other offices of the Public Security Bureau, and I will go to the Exit and Entry Control Division now."

Xu Dayuan nodded, Zhang Sannian took people away, and Da Zhao looked puzzled.

"How do I feel, Zhang Da's face is not good-looking, did you find something?"

Xu Dayuan didn't speak, and Zhou Ning narrowed his eyes slightly.

"The entry and exit management department of a county-level city generally has a small staff, only two or three people, and there are still people at the window to handle business, so it is really in the office

People, maybe Zhang Da knows."

Xu Dayuan nodded, he didn't feel comfortable like this, after all, he had been a police officer for many years, and among the people he knew, there were times when he couldn't figure it out, and he reported to the suspect, or cheated for personal gain.

After being silent for a long time, Xiao Zeng and Xiao Bai walked over quickly, followed by an old couple, the two were dressed plainly and neatly, with a nervous face, Xu Dayuan waved his hand, signaling the two to take the Xu family's parents to the conversation room next to it, the only difference between here and the interrogation room is that there is no interrogation chair, but there are a few chairs next to a table, but there is still an observation room next door.

Xu Dayuan glanced at Zhou Ning, Zhou Ning nodded hurriedly, this means that he knows that he is asking him to go to the observation room to watch, Xu Dayuan took Xiao Zeng Xiaobai and entered the conversation room.

With so many policemen, the old husband and wife were full of nervousness, pulling each other's arms, and under Xu Dayuan's signal, the two sat across the table.

"Xu Xiangnian and Zhang Shan, right? Introduce yourself, don't be nervous, let's just talk, understand the situation, make a record for the two of you, just know what to say, if you feel bad heart, we have medicine here, you can take it in advance."

The old couple nodded, seeing that the police were so polite, they felt a lot less nervous in an instant, and Xu's father spoke first.

"My name is Xu Xiangnian, born in 1955, 58 years old this year, graduated from Jiangsu and Zhejiang Provincial Health School in 1973, studied clinical medicine, and then I returned to our village children's brigade as a hygienist.

Xu Dayuan nodded and looked at Xu's mother Zhang Shan.

"My name is Zhang Shan, born in 1956, one year younger than him, took the college entrance examination in 77, I graduated from Lu Normal University, the eldest Xu Qing, who was born that year of graduation, was directly assigned to Sun Shouzhen Middle School, and just retired last year."

"The old man in the family didn't have it at the end of last year?"

Xu Xiangnian snorted.

"My father didn't have a 92nd birthday at the end of last year, and the old man has a very stubborn temper, but I'm the youngest son, and I can only take good care of it, I don't know what you want to ask?"

Xu Dayuan looked at the two of them, stared at their eyes and said:

"I want to know, the year of Xu Dan's college entrance examination, that is, August 12, 2002, are you at home? Who is in the house?"
