Chapter 74 Xu Da, I have a way
The car was driving fast on the road, Da Zhao looked at Zhou Ning who was on the co-pilot from time to time, but Zhou Ning kept his eyes closed and didn't speak, he scratched his head in anxiety.

"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, you asked the boss and the others to go to the Eighth Hospital, and you asked someone to open the dissection room and find The sample you kept?"

Zhou Ning didn't speak, Da Zhao pursed his lips, and couldn't help stepping on the accelerator hard. After 10 minutes, the car finally stopped in the backyard of the Eighth Court.

After getting off the car, Xu Dayuan had already brought people to wait here.

"Zhou Xiaozhou, what did you find?"

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

Zhou Ning signaled everyone to enter the autopsy room. Once in, Da Zhao kept rubbing his hands. The car's air conditioner was not warm enough, and the windows were still open at the scene. Now he was terribly cold, standing at the air conditioner outlet, shivering constantly.

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

Seeing this, Zhou Ning let out a sigh of relief, but everyone around him looked at him suspiciously, he coughed, he was so involved that he even forgot to explain.

"That's right, we just went to the first scene for a second survey, and this time we found a pair of porcelain doll fragments made when the deceased married Zhang Xin, and found blood fingerprints on one of them, and the fingerprints belonged to Zhang Xin.

In addition, in the window of the living room, there were blood fingerprints inside and outside, which were also Zhang Xin's. The photos sent to you by Da Zhao just now are the results of the comparison, but these fingerprints can only prove that Zhang Xin was at the scene, and the porcelain was smashed. 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 splashes remaining at the scene, the murderer rode on the dead body and smashed his head. I can now prove that the murderer was cutting Finished after the genitals of the deceased.

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

You can tell the laboratory of the Municipal Bureau to try to extract blood cells from this urine sample, and then conduct DNA identification, and send the shorts and pants on Zhang Xin's body for inspection together. Only when riding on the dead will the dead remain in the crotch Bloodstains, I think Zhang Xin also overlooked this point. "

Zhou Ning spoke very fast, and he was a little annoyed when he finished speaking. He felt that what he said was a bit messy. 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 between the crotch of the deceased, and the blood on Zhang Xin's pants is the best evidence, right?"

Zhou Ning nodded vigorously.

"Correct!"

Xu Dayuan waved his hand and directed behind him:
"What are you doing in a daze? Go to the emergency department and ask the doctor where Zhang Xin's pants are. I'm still wearing them after I changed them. I'm going to get them now. Hurry up!"

With such an order, Liu Changhai rushed out with people.

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

"How are you?"

Zhou Ning waved his hand.

"It is estimated that he spoke too fast, and there is some lack of oxygen."

Big Zhao spat.

"Come on, that's hungry. I ask you, have we eaten after one noon?"

After finishing speaking, Da Zhao glanced at Xu Dayuan. Xu Dayuan looked over in surprise, and then glanced at the hands on the watch. It was past eleven o'clock at this time.

"You didn't eat?"

Da Zhao curled his lips, as if he really felt aggrieved. After all, fat people can't resist hunger, especially for a new fat person like him who has suddenly gained more than 30 catties, his eyes are sparkling.

"It's not just that I didn't 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 suppressed a smile, and patted Da Zhao and Zhou Ning on the shoulders.

"Don't make such an expression on me. Let's go to the emergency room together. If you find physical evidence, let them send it for inspection. You two should hurry back and rest. If it's not right, I'll treat you to the head office, right?"

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

"I see OK, I know a 24-hour buffet."

As the two said this, Zhou Ning seemed to feel the discomfort from his stomach and intestines. 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 already arrived at the emergency room, several nurses were constantly looking for trash cans, Liu Changhai was scratching his hair, the anxiety on his face was beyond words, Zhou Ning thought of two words in an instant.

broken!

"what happened?"

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, just in time for the shift, the new nurse who took over didn't know that this was the suspect we left behind, So I changed Zhang Xin into a set of hospital gowns.

I just put the clothes in a bag, and I want the cleaning to clean it. I guess she will be busy later, and she forgot about it. When we asked just now, she found that the bag was missing. I sent 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 gowns, obviously changed after that time period.

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

Xu Dayuan frowned.

"After the project meeting, I sent someone over. It was already three o'clock in the afternoon. It was people from the port police station who sent Zhang Xin to the hospital. They explained that they didn't keep anyone."

"Can't you adjust the monitoring?"

Liu Changhai's forehead was sweating, and he hurriedly said to Zhou Ning.

"Lao Xing is on duty at night in the guard room. This guy is good at looking at the gate, and he doesn't know a few big characters. I just asked. He doesn't know how to call the surveillance, and he doesn't know the password."

Da Zhao leaned over, raised his hand and pressed down.

"Don't worry, I'm looking for a master, he's a professional."

Zhou Ning knew that Da Zhao wanted to ask Xiao Hu and the others to take action, but today he really made the most of everything he had, restoring deleted content on the computer, exporting mobile phone information, and comparing fingerprints. .

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

"Hey guys, are you hungry? I'm going to prepare some supper for you. How about skewers? Don't be polite to me. Ah, you guys are so awesome, so you're exporting some of the phone content?
So don’t hurry, I’m on the road for 5 minutes to the police station, you can just go downstairs, how can you be so useless, we have to kill our leader, you can just go upstairs and downstairs, hang up! "

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

"I'm going to pick up people. When I come, go directly to the guard room. By the way, boss, you're going to bleed tonight. I said that the buffet is on Cha'an Road, south of the Eighth Courtyard. Shall we go directly after finishing work?"

Xu Dayuan raised his leg and kicked directly on Da Zhao's ass.

"There's a lot of bullshit, hurry up and pick someone up, we'll go to the guard room later."

"That's it!"

Big Zhao ran away with a hippie smile on his face. This man has a thick skin and can also liven up the atmosphere. For a while, everyone was less nervous than before. The two nurses in the emergency department still had nervous expressions, and Zhou Ning smiled at them.

"Don't be nervous. You will find out after checking the monitoring in a while. You are busy first. We are very embarrassed to disturb your work like this."

The two little nurses nodded gratefully, Xu Dayuan waved his hands, and the two hurried away.

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

"Four shifts a day, two people in each shift, let me stare at Zhang Xin, if something happens, I'll be the first to clean it up, remember?"

Liu Changhai smiled wryly, and quickly said yes, Zhou Ning thought for a while, leaned closer, and said in a low voice:

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

Xu Dayuan raised his eyebrows, and suddenly became interested.

"Tell me."
