The car was driving fast 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 scratched his head and scratched his head anxiously.

"I said, we don't want to pretend to be asleep, but you satisfied my curiosity. What did you find? You asked me to take pictures, asked the boss and others to go to the Eighth Hospital, and asked them to open the anatomy room and find

The sample you kept?"

Zhou Ning didn't say anything, Da Zhao pursed his lips and couldn't help but press the accelerator hard. Twenty minutes later, the car finally stopped in the backyard of the Eighth Courtyard.

When we got off the bus, Xu Dayuan was already waiting here with people.

"Zhou Xiaozhou, what did you find?"

"Xu Da, let's go in and talk."

Zhou Ning signaled everyone to enter the anatomy room. As soon as they entered, Da Zhao kept rubbing his hands. The car's air conditioner was not good at heating, so he kept the windows open at the scene. Now he was completely cold and stood at the air conditioner vent, shivering constantly.

Zhou Ning directly found the samples that were sampled in the morning, rummaged around, took out a bottle with yellow liquid, and then dipped it in with a swab. With the other hand, he took a phenolphthalein solution and hydrogen peroxide with a straw, and swabbed them separately.

On the swab, the swab turns pink instantly.

Seeing this, Zhou Ning exhaled, but everyone around him looked at him in confusion. He coughed. He was so involved that he forgot to explain.

"That's right, we just went to the first site for a second investigation. This time we found a pair of fragments of porcelain dolls made when the deceased and Zhang Xin were married. We found bloody fingerprints on one of them. The fingerprints belong to Zhang Xin.

In addition, at the living room window, I found bloody fingerprints both inside and outside. These belong to Zhang Xin as well. The photo that Zhao just sent to you is the result of the comparison, but these fingerprints can only prove that Zhang Xin was at the scene and smashed the porcelain.

The doll opened the window.

I went to the master bedroom to do a simulation of the murder process. After all, judging from the direction of the blood dripping left at the scene, the murderer was riding on the deceased and hitting his head. And these actions, I can now prove, it was the murderer who was cutting the head.

Finished after the deceased's genitals.

You see, this is urine on the bathroom floor. There is a pool of blood next to it, which is some distance from the urine. Zhang Xin acted like she was incontinent in order to make people think she was crazy.

You can tell the city bureau's laboratory department to 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 riding on the deceased will the deceased be left in the crotch.

Blood stains, I think Zhang Xin also ignored this."

Zhou Ning spoke very quickly, and was a little annoyed when he finished speaking. He felt that what he said was a bit confusing. He didn't know if Xu Dayuan and the others understood it, but looking at Xu Dayuan's expression, he seemed to understand the key point.

"You mean, the murderer is riding on the deceased's crotch, and the blood stains on Zhang Xin's pants are the best evidence, right?"

Zhou Ning nodded vigorously.

"right!"

Xu Dayuan waved his hand and ordered behind him:

"What are you doing standing there in a daze? Go to the emergency department and ask the doctor where Zhang Xin's pants are, whether they are still on after they have been changed off or on. I need to get them now, quickly, quickly!"

With such instructions, Liu Changhai rushed out with his people.

Zhou Ning shook his head, sat down on the chair, and Zhao came over.

"How are you doing?"

Zhou Ning waved his hand.

"I guess he spoke too fast and lacked oxygen."

Da Zhao spat.

"Come on, you are hungry. Let me ask you, have we eaten after one o'clock at noon?"

After saying that, Da Zhao glanced at Xu Dayuan. Xu Dayuan looked over in surprise, and then looked at the hands on the watch. It was already past eleven o'clock.

"You haven't eaten?"

Da Zhao curled his lips, as if he really felt aggrieved. After all, fat people don't resist hunger, especially a new fat guy like him who suddenly gained more than thirty kilograms, and there was a glint in his eyes.

"Not only did I not eat, I didn't even take a sip of water. Seeing Zhou Xiaozhou anxious, I followed him around and the car ran out of gas."

Xu Dayuan held back his laughter and patted Da Zhao and Zhou Ning on the shoulders.

"Don't give me this expression. Let's go to the emergency room together. If we find any physical evidence, ask them to send it for examination. You two should go back and rest as soon as possible. Why don't I treat you two to a meal at the head office?"

Da Zhao suddenly pulled the corners of his mouth to the base of his ears, sweeping away the previous haze.

"I think it will work. I know a twenty-four-hour buffet."

As the two of them talked, Zhou Ning seemed to feel discomfort coming from his gastrointestinal tract. The long-term hunger made his stomach ache a little, but he found something and felt that everything was worth it.

Thinking in his mind, the three of them had arrived at the emergency room. Several nurses were rummaging through the trash cans. Liu Changhai was grabbing his hair. The anxiety on his face was clear. Zhou Ning thought of two words in an instant.

broken!

"What's wrong?"

Liu Changhai hurried over and said anxiously:

"Zhang Xin made a big fuss during lunch, smashed a lot of monitoring equipment, and spilled the food on the bed. It was just before the shift was over, and the new nurse who took over didn't know that this was the suspect we left behind.

I directly changed Zhang Xin into a hospital gown.

I just put the clothes in a bag and asked the cleaners to clean it. I guess she will be busy later and she forgot about it. When we asked about it just now, she realized that the bag was missing. I asked someone to find the trash can.

There is no result yet.”

Zhou Ning pondered for a moment. When he and Da Zhao came, Zhang Xin was wearing his own clothes, not hospital clothes. He obviously changed his clothes after that period of time.

"Didn't Xu Da send someone to monitor him?"

Xu Dayuan frowned.

"After the project meeting, I sent someone over. It was already three o'clock in the afternoon. The people who took Zhang Xin to the hospital were people from the port police station. They finished explaining but no one was left."

"Can't you adjust the monitoring?"

Liu Changhai was sweating on his forehead, and he hurriedly said to Zhou Ning.

"The man on duty in the guard room at night is Lao Xing. He can only read the gate. He doesn't know a few characters. I just asked him. He doesn't know how to call up the surveillance, and he doesn't know the password."

Da Zhao came over and raised his hand to press down.

"Don't worry, I'll find an expert. They are professionals."

Zhou Ning knew that Da Zhao wanted to ask Xiao Hu and the others to take action. Today, he really made the best use of everything. He restored the deleted content on the computer, exported the mobile phone information, and compared the fingerprints. Now it's good that even surveillance is done.

.

But there was no good way, Zhou Ning chose to shut up, and Da Zhao's phone number was dialed.

"Hey guys, are you hungry? I'm going to prepare some midnight snacks for you. How about skewers? Don't be polite to me. Ah, you guys are so awesome. Are you going to export part of the content on your phone?

Then don't leave in a hurry. I was on the road for five minutes and arrived at the police station. You can just go downstairs. You can't do anything for nothing. Our leader must be killed. You can just put on your clothes and go downstairs. Hang up!"

After speaking, Da Zhao hung up the phone and handed Zhou Ning the camera and the box.

"I'm going to pick you up. When you get here, go straight to the guard room. By the way, boss, you're going to have to bleed tonight. I said the buffet is on Cha'an Road south of the Eighth Courtyard. Can we go straight there after we finish our work?"

Xu Dayuan raised his leg and kicked Da Zhao directly on the butt.

"That's a lot of nonsense. Hurry up and pick someone up. We'll go to the guard room soon."

"It's done!"

Da Zhao ran away with a smile on his face. This man was thick-skinned and could liven up the atmosphere. For a moment, everyone was less nervous than before. The two nurses in the emergency department still had nervous expressions. Zhou Ning smiled at them.

"Don't be nervous. You will know after checking the surveillance system in a moment. You go ahead and do your work. We are very embarrassed to disturb your work like this."

The two young nurses nodded gratefully, Xu Dayuan waved his hands, and they ran away quickly.

Then Xu Dayuan glanced at Liu Changhai and stretched out two fingers.

"There are four shifts a day. There are two people in each shift. Keep an eye on Zhang Xin for me. If anything happens again, I will be the first to deal with you. Remember?"

Liu Changhai smiled bitterly and quickly said yes. Zhou Ning thought for a moment, came closer and said in a low voice:

"Xu Da, actually it's not easy to monitor in the emergency room, and there are so many people coming and going here, it's not easy for Zhang Xin to show off. I have a way."

Xu Dayuan raised his eyebrows and suddenly became interested.

"Tell me."
