Chapter 74: Xu Da, I have a solution
The car was speeding on the road. Da Zhao looked at Zhou Ning in the passenger seat from time to time, but Zhou Ning kept his eyes closed and didn't speak. He was so anxious that he scratched his ears and cheeks.
"I say, we can't pretend to be asleep. Why don't you satisfy my curiosity? What did you find? You want me to take pictures, and you want the boss and others to go to the Eighth Hospital, and you want someone to open the autopsy room to look for the samples you kept?"
Zhou Ning didn't say anything. Da Zhao pursed his lips and stepped on the accelerator hard. Twenty minutes later, the car finally stopped in the backyard of the Eighth Hospital.
As soon as I got off the car, Xu Dayuan and his men were already waiting here.
"Zhou Xiaozhou, what did you find?"
"Xu Da, let's go in and talk."
Zhou Ning motioned for everyone to enter the autopsy room. As soon as Da Zhao came in, he kept rubbing his hands. The car's air conditioning and heating were not working well, so the windows were still open at the scene. Now he was freezing cold, and he stood at the air outlet of the air conditioner, shivering constantly.
Zhou Ning went straight to the samples taken in the morning, rummaged through them, took out a bottle of yellow liquid, then dipped a swab in it. With his other hand, he used a pipette to take phenolphthalein solution and hydrogen peroxide, respectively, and put them on the swab. Instantly, the swab turned pink.
Seeing this, Zhou Ning breathed a sigh of relief, but the people around him looked at him in confusion. He coughed and realized that he was so engrossed in the conversation that he forgot to explain.
"It's like this. We just went to the first scene for a second investigation. This time we found a pair of porcelain doll fragments made when the deceased and Zhang Xin got married. We found a bloody fingerprint on one of the dolls, and it was Zhang Xin's.
In addition, bloody fingerprints were found inside and outside the living room window. These were also Zhang Xin's. The photos that Da Zhao just sent you were the results of the comparison, but these fingerprints can only prove that Zhang Xin was at the scene and opened the window to smash the porcelain doll.
I went to the master bedroom and simulated the murder process. After all, judging from the direction of the blood splatters left at the scene, the murderer was riding on the victim and hitting his head. I can now prove that these actions were performed by the murderer after cutting off the victim's genitals.
Look, this is urine on the bathroom floor. There is a pool of blood next to it, which is some distance away from the urine. In order to make people think that she is crazy, Zhang Xin acted out incontinence.
You can talk to the Municipal Bureau's Inspection Department and try to extract blood cells from this urine sample, and then conduct DNA identification, and send Zhang Xin's shorts and pants for inspection. Only when she was riding on the deceased would there be traces of the deceased's blood between her legs. I think Zhang Xin also overlooked this point."
Zhou Ning spoke very quickly and felt a little annoyed after he finished speaking. He felt that what he said was a bit confusing and didn't know whether Xu Dayuan and the others understood him. However, looking at Xu Dayuan's expression, it seemed that he understood the key point.
"You mean, the murderer was riding on the victim's crotch, and the blood on Zhang Xin's pants is the best evidence, right?"
Zhou Ning nodded vigorously.
"right!"
Xu Dayuan waved his hand and said behind him:
"What are you standing there for? Go to the emergency department and ask the doctor where Zhang Xin's pants are. She's still wearing them after she changed them. I need them now, quick!"
After giving the order, Liu Changhai led his men out.
Zhou Ning shook his head and sat down on the chair. Da Zhao came over.
"How are you?"
Zhou Ning waved his hand.
"I guess I spoke too fast and I'm a little short of oxygen."
Da Zhao spat .
"Don't come on, I'm just hungry. I'm asking you, did we eat after 1pm?"
After saying that, Da Zhao glanced at Xu Dayuan. Xu Dayuan looked at him with some surprise, and then glanced at the hands on his watch. It was already past eleven o'clock.
"You didn't eat?"
Da Zhao curled his lips, as if he was really feeling aggrieved. After all, fat people cannot resist hunger, especially a new fat guy like him who suddenly gained more than 30 pounds. There was some sparkling in his eyes.
"Not only did I not eat, I didn't even drink a sip of water. Seeing Zhou Xiaozhou getting anxious, I followed him and the car ran out of gas."
Xu Dayuan held back his laughter and patted Da Zhao and Zhou Ning on the shoulders.
"Stop making that face. Let's go to the emergency room together. If we find any evidence, have them send it for examination. Then you two can go back and have a rest. I'll treat you two to a meal, okay?"
Da Zhao's mouth corners suddenly pulled up to his ears, and the previous gloom was swept away.
"I think so. I know a 24-hour buffet."
As the two talked, Zhou Ning seemed to feel some discomfort in his stomach. The long period of hunger made his stomach ache slightly, but he felt that it was all worth it as he had made some discoveries.
Thinking in his mind, three people have arrived at the emergency room, several nurses are constantly rummaging through the trash cans, Liu Changhai is grabbing his hair, and the anxiety on his face is beyond words. Zhou Ning instantly thought of two words.
broken!
"What's wrong?"
Liu Changhai ran over and said anxiously:
"Zhang Xin made a big scene during lunch, smashing a lot of monitoring equipment and spilling food all over the bed and body. It happened to be before the shift change, and the new nurse didn't know that this was the suspect we left behind, so she directly changed Zhang Xin into a set of hospital gowns.
She just put the clothes in a bag and wanted the cleaner to wash them. I guess she was busy afterwards and forgot about it. When we asked her just now, she realized that the bag was missing. I asked someone to look for a trash can, but there is no result yet. "
Zhou Ning pondered for a moment. When he and Da Zhao came, Zhang Xin was wearing her own clothes, not a hospital gown. It was obvious that she changed her clothes after that time period.
"Didn't Mr. Xu send someone to monitor here?"
Xu Dayuan frowned.
"I sent someone here after the special case meeting. It was already three o'clock in the afternoon. The people who brought Zhang Xin to the hospital were from the Gangkou Police Station. They didn't keep anyone after they explained the situation."
"Can't you adjust the surveillance?"
Liu Changhai's forehead was covered with sweat , and he hurriedly spoke to Zhou Ning.
"The person on duty at the security room at night is Old Xing. He can only look after the gate, but he can barely read a few characters. I just asked him, but he doesn't know how to access the surveillance video, let alone the password."
Da Zhao came over and raised his hand to press down.
"Don't worry, I'll find an expert, he's a professional."
Zhou Ning knew that Da Zhao wanted Xiao Hu and the others to take action. Today, they really made full use of their resources, recovering deleted content on the computer, exporting mobile phone information, and comparing fingerprints. Now, they even let them do surveillance.
But there was no good way, so Zhou Ning chose to keep quiet, as Da Zhao's call had already been connected.
"Hey guys, are you hungry? I'm going to prepare some midnight snacks for you. How about some kebabs?... Don't be polite with me... Ah, you guys are so awesome. Are you going to export part of the phone content right now?
... Well, don't leave in a hurry. I'll be at the police station in five minutes. You can just go downstairs . You can't order people around like this for nothing. We must kill our leader. Just put on your clothes and go downstairs. I'm hanging up!"
After saying that, Da Zhao hung up the phone and stuffed the camera and the box into Zhou Ning's hands.
"I'm going to pick someone up. Go straight to the guard room when you get here. By the way, boss, you have to bleed tonight. I said that the buffet is on Cha'an Road south of the Eighth Courtyard. Can we go there directly after we finish our work?"
Xu Dayuan raised his leg and kicked Da Zhao directly on the butt.
"So much nonsense, hurry up and pick them up, we'll go to the guard room later."
"It's settled!"
Da Zhao ran away with a grin on his face. This man was thick-skinned and knew how to liven up the atmosphere. Suddenly, no one was as nervous as before. The two nurses in the emergency department still had nervous expressions, and Zhou Ning smiled at them.
"Don't be nervous. We'll know after checking the surveillance. Go ahead and do your work. We're really sorry to interrupt your work like this."
The two young nurses nodded gratefully, Xu Dayuan waved his hand, and the two of them quickly ran away.
Then Xu Dayuan glanced at Liu Changhai and stretched out two fingers.
"We work four shifts a day, two people per shift. Keep a close eye on Zhang Xin. If anything goes wrong again, I'll be the first one to deal with you. Remember that?"
Liu Changhai smiled bitterly and quickly said yes. Zhou Ning thought for a moment, moved closer, and said in a low voice:
"Master Xu, it's actually not easy to monitor in the emergency room. Besides, there are so many people coming and going here, and it's not easy for Zhang Xin to reveal her tracks. I have a solution."
Xu Dayuan raised his eyebrows and immediately became interested.
"Tell me."
