Zhou Ning was a little surprised. Since Forensic Doctor Liu was going to solve it, that would be even better. He patted He Shancun's arm.
"Hey guys, it's your turn. Remember to wear your masks. Someone will help you take them off. Let Da Zhao take the photos. You don't have to be fast. Just check carefully against the medical records I gave you."
"Don't worry, I have experience!"
Zhou Ning grabbed the headset and stared at the interrogation room behind the one-way glass.
He Shancun and others walked into the interrogation room. Da Zhao and He Chunyang handcuffed Cui Guanglin to a stretcher on the left and right. Cui Guanglin struggled constantly due to being restrained in this way, staring at several people and shouting continuously.
"What are you going to do? What are you going to do?"
Xu Dayuan walked to the side and held up the thick stack of reports.
"This is the result of comparing the extract from your finger scab with the DNA found in the body of the deceased on March 10. Do you see the conclusion here? The two DNAs are exactly the same and the test results show that they are from the same person. This means that your blood was left in the body of the deceased.
However, what surprised us was not this, but the discovery that your DNA test showed an XXY sex chromosome abnormality. We also found the case of your examination in the provincial hospital.
However, although there is a screenshot of your screen on this case, it is not your real name, so we need to verify it. Don't worry, we won't draw blood, we are just checking it, understand, just relax."
This explanation did not calm Cui Guanglin down. Instead, it made him twist his body like crazy, with his legs hooked around each other like a twist, and his pants tightly clamped together. Policeman Wang was unable to take any action for a while.
He Shancun came closer, took a look, patted his colleague, and the two of them lowered the backrest of the stretcher completely. In this way, Cui Guanglin, with his height, was stretched straight and his legs were completely spread apart.
The policeman named Wang was very angry. He untied Cui Guanglin's belt and buttons with one hand, and pulled down hard. His pants were pulled off directly. He Shancun stepped forward and gave the policeman named Wang a thumbs up.
He pulled Cui Guanglin's clothes upwards, so that all the exposed parts were exposed. Da Zhao came over and took pictures quickly following the direction of He Shancun's finger.
Of course, the private part between the legs was lifted up by He Shancun, and with this pull, the ball and the crack below were also exposed .
Zhou Ning saw clearly that Cui Guanglin had a small scar on the right lower abdomen. The location and size of the scar must have been left by an appendectomy. So, he must have conducted corresponding examinations during the operation, which is why he discovered his difference.
"He has no beard, sparse pubic hair, underdeveloped reproductive organs, an inconspicuous Adam's apple, unilateral cryptorchidism, and incomplete development of the female vulva. I don't have duckbill forceps with me so I can't examine the inside. For a detailed examination, it will require B-ultrasound. However, his previous medical records show that the internal reproductive appendages, uterus and other structures are missing."
After saying this, He Shancun loosened his hands and took off his gloves. The policeman named Wang was still humane and helped Cui Guanglin pull up his pants, but he pulled the belt down directly.
It was estimated that the person was captured in a hurry and this report was not received at that time. The situation was different now. Da Zhao acted quickly. He grabbed the luminol reagent and sprayed it on his belt, which turned a fluorescent color.
Da Zhao just grinned and opened an evidence bag.
"Here, put the belt here. There are many marks of being hit by the belt on the deceased. This needs to be sent for inspection."
He Shancun wrote a physical examination form, signed his name on it considerately, and handed it to Xu Dayuan.
"Master Xu, this is the end of the simple physical examination. We will leave first."
Xu Dayuan nodded to He Shancun.
"Thanks!"
"You're welcome, but you need to return the stretcher to us. It went with the car. If you don't return it, I can't explain it, let alone pay 120."
Xu Dayuan waved his hand, and police officers Da Zhao and Wang came up together, uncuffed Cui Guanglin, and handcuffed him to the interrogation chair again.
At this time, Cui Guanglin no longer had the clamor he had before, and seemed to have wilted and was at the mercy of others.
After He Shancun and the others left, Zhou Ning just waved to him without saying anything more, then quickly grabbed the headset.
In the interrogation room, Xu Dayuan folded his arms, leaned against the table, stared at Cui Guanglin without saying a word. After Da Zhao finished cleaning up, he retreated. Cui Guanglin did not raise his eyes, just stared at the handcuffs on his hands.
Quiet.
The entire interrogation room was very quiet. There was no previous lecture, nor was there the roar that Cui Guanglin had just heard when he was examined by He Shancun. However, such silence seemed to have frozen the air in the entire interrogation room.
Although Cui Guanglin did not raise his head, the rise and fall of his chest was very obvious. At least this man was not as calm as he appeared to be.
Da Zhao had already walked to Zhou Ning's side and glanced anxiously at the interrogation room.
"This guy is too calm. I don't think he cares whether his parents know or decide to lose face. As for being stripped and inspected, I don't think he finds it difficult to accept. What should I do?"
Zhou Ning shook his head, and Da Zhao was a little puzzled.
"What do you mean? You don't agree with me?"
"Wait, Cui Guanglin will speak. He killed someone and successfully evaded the police. It's such a pity that no one shares such a great achievement.
The stimulation from Cui's mother and He Shancun just now was to make him lose his composure. As a teacher and a people-pleasing person, Cui Guanglin has reached his limit and may soon release the person he is hiding. "
Da Zhao blinked, his face full of disbelief.
"I said, are you making a movie? What's this about multiple personalities? I've seen it in a movie. What's the name of that movie? Oh, ID. I've never heard of it or seen it in real life. Are you saying that when he kills people, it's his other personality that does it and he doesn't know it?"
Zhou Ning shook his head.
"I don't know how to put it. Even if a person pretends, it can be done for a while, but he can't completely hide his cruel and bloodthirsty side. When I first met Cui Guanglin that day, his gentleness was not fake.
But when Second Aunt mentioned the physical examination, I can never forget the look in her eyes. In that instant, you realized that this person was no longer the gentle and elegant Cui Guanglin before.
Looking at the interrogation room in front of me, Cui Guanglin has been interrogated for a day and a night. Most people would have been exhausted, but look at him, he has been staring at the ground, as if all the preaching has nothing to do with him. But I watched the interrogation last night, and if you observe carefully, you will find that their expressions are different.
I think that he used different Cui Guanglin to deal with the interrogation, so it was like taking turns to rest, so he was not so tired. I didn't say much to Xu Da and the others just now because all this is just speculation. It depends on whether these stimuli are effective.
After all, in Cui Guanglin's eyes, whether it was the good teacher Cui Guanglin, the murderer who enjoyed killing, or the gentle , the relationship between them was very subtle, both a competitive relationship and a mutually supportive relationship. "
Da Zhao stared blankly at the scene in front of him. Everything Zhou Ning said seemed a bit shocking at first, but when he thought about it carefully, it really made sense.
"It sounds reasonable, but we have done everything we can, so all that's left is to wait!"
Zhou Ning nodded.
"Yes, we have done what we should do. All we can do is wait."
Zhou Ning didn't say anything else, but turned to look into the interrogation room. Xu Dayuan was not too leisurely, nor did he completely ignore the matter. He just folded his arms, lit a cigarette, and looked at Cui Guanglin in front of him.
"Are your grandparents nice to you?"
Cui Guanglin didn't say anything, but Xu Dayuan was not discouraged. He didn't care at all and sat directly opposite Cui Guanglin.
"It seems normal. Your parents gave birth to you and left you to your grandparents. I think a big reason is because of your health, right? So you blame them, you blame your parents for not accompanying you to grow up early, not taking you to see a doctor earlier, or simply not letting you grow up.
I remember that forensic doctor Zhou said that if you had such an operation when you were young and kept one gender, even if there would be defects in your genes, your life would not be like this, at least not like it is now, right?"
Cui Guanglin lowered his head, gritted his teeth and pursed his lips. This action made Zhou Ning's heart move. It was good to have a reaction, at least it meant that the previous work was not in vain.
Thinking of the scar from the appendectomy surgery, Zhou Ning picked up the phone and turned on the call button.
"Master Xu, when they were doing the physical examination just now, I saw a surgical scar on Cui Guanglin's abdomen. It should be an appendectomy operation. I think he went to the provincial capital for a checkup in August 2004 because of this. Can you ask from this angle?"
Xu Dayuan did not cover his ears. He listened to Zhou Ning's words carefully. He just took out a cigarette, lit it, and blew a puff of smoke towards Cui Guanglin. Cui Guanglin closed his eyes and fanned away the smoke.
"Why don't you tell me why you went to the provincial capital for a physical examination? Looking at the scar on your stomach, it should be a few years old. Did you have an appendectomy operation? Did you discover your health problems because of this operation?"
Cui Guanglin's body trembled, and the handcuffs on his hands made a rattling sound as he moved. He raised his head, and his face no longer had the indifference he had before. He stared at Xu Dayuan with fear in his eyes.
"Are you the police or the devil? Is there really no privacy in front of you?"
