"Okay leader, I'll check this information."

"Don't be in a hurry to hang up the phone, from now on, your diet must be eaten with the staff of the local bureau, you can't go out alone, especially you can't eat and drink the food that is given at will, we found poisoning here, okay, don't do it, hurry up and work."

Xu Dayuan hung up the phone, and it was estimated that He Chunyang was confused at this time.

At this moment, Lao Liang in the cafeteria and a few people came up with a large number of hot water bottles, rubbed their hands with an apologetic face, and clasped their hands together towards Xu Dayuan.

"I'm sorry Xu Ju, if it weren't for the broken gas stove in the canteen today, I wouldn't be able to order food outside, and there wouldn't be poisoning, it's all my problem."

Xu Dayuan waved his hand.

"It's okay, go to two people, follow Lao Liang to see the gas stove, don't light the fire easily, first open the doors and windows to ventilate, and then take the flashlight to go in to check, don't light the fire easily, just check if there is a problem with the pipeline, and seal it directly if you find anything."

A few people went out, Da Zhao distributed instant noodles and ham sausages to everyone, one by one they were bitter, there were no complaints, after all, everyone was hungry, Zhou Ning ate quickly, saw Xia Momo poking him, looked down, and found that Xia Momo handed over a braised egg, Zhou Ning smiled and shook his head.

"You eat, follow Zhu Xingxing and them back to the hotel after eating, and they will be interrogated overnight tonight."

Zhu Xingxing looked worried, shook his head and put the braised egg in Zhou Ning's noodle bowl.

"I'm not going to hold you back, but this one is going to be eaten."

After speaking, Xia Momo and Zhu Xingxing sat together, Zhu Xingxing has always comforted Zou Jialong, after all, he is responsible for receiving the box lunch, and self-blame is inevitable.

Da Zhao gave Zhu Xingxing a look, Zhu Xingxing quickly got up, Da Zhao walked closer, lowered his voice and said:

"A few meanings, what problems can self-blame solve, whether it can catch the murderer who poisoned the case, or whether it will promote the investigation of the case, if it is useful, I will blame myself with you, of course, if you can't adjust your emotions well in such a problem, then simply go back to Qindao."

Zou Jialong was startled and hurriedly waved his hand at Da Zhao.

"Brother Zhao, I don't mean anything else."

Zhao Xinli waved his hand.

"Don't talk nonsense, take samples from all the lunch boxes and keep samples for freezing, mark them clearly for me one by one, and collect fingerprints and DNA on the outside of the lunch boxes, it's not good for someone to send us questions, can you do it?"

"Competent, we'll go right away."

Saying that, Zou Jialong jumped up, dragged Pang Tianhang and a few people from the technical department, and quickly went to deal with the lunch box, Da Zhao smiled and Mei Zizi struggled towards his double instant noodles, and there was no soup left for a moment.

At this time, there was the sound of the car braking sharply downstairs, and many people looked downstairs, Tao Zhenshan came back, and someone behind him was carrying a wooden plank, which seemed to be a corpse, and his head was covered with a kitchen overalls.

Xu Dayuan's heart was cold, and he waved his hand towards Zhou Ning and Da Zhao.

"You two go and take a look, it is estimated that the driver who delivered the food has been killed, and see if any clues can be found on the corpse."

Zhou Ning nodded and glanced at Xiaoqu.

"I'll go to the autopsy, you use the software here to make an accurate inference, what are the height and weight of the food delivery driver, and what behavioral characteristics are there, and send it to me directly in a while."

Xiaoqu hurriedly agreed, Zhou Ning and Da Zhao walked quickly towards the dissection room, Zhu Xingxing got up and Zhou Ning waved his hand.

"You and Xia Momo take the bus back to the hotel, you don't need you here, you come early tomorrow morning to take over the work, tonight we will rotate continuously, we can't all stay up."

Zhu Xingxing nodded, dragged Xia Momo and left.

Zhou Ning came to the dissection room, Peng Shinian and Da Zhao followed, and sure enough, Tao Zhenshan and they were already carrying the wooden board inside, and when they saw Zhou Ning, they spat on the ground.

"It's late, it looks like someone killed someone, a knife stabbed in the heart, quite professional, and the knife was not pulled out, I looked at the back of the corpse, the tip of the knife was almost pierced.

The door was open, the car key was inserted in the keyhole, and the body was in the driver's seat, but there were blood stains on the edge of the co-pilot, and I suspect that the deceased was killed while sitting in the co-pilot's seat, and there was nothing left on his mobile phone wallet, and the glove box was also open, and the scene was disguised as a robbery. ”

Zhou Ning glanced at the corpse, stretched out his hand to lift his clothes, the deceased was wearing a yellow short-sleeved T-shirt, there were irregular blood stains less than ten centimeters in diameter around the wound, the wound looked like the width of the blade, the deceased's legs were slightly bent, the eyelids were slightly open, the mouth was slightly open, and the five fingers of both hands were bent, as if they were about to grasp, and they were only slightly raised.

"I'll take a look, and I'll give you the results of an autopsy immediately, do the deceased Yunliangang have any relatives?"

"I haven't checked it yet, I'll go to the household registration information in a while."

Zhou Ning glanced at the time, and Xu Dayuan raised his chin at him.

"Say what you think."

"It's only eight o'clock now, the deceased delivered food at 19:10 to the public security bureau, the time to go out will be earlier, the food delivery is across the road, so long people haven't gone back, no one is looking for the owner of the hotel?"

Tao Zhenshan and Xu Dayuan glanced at each other and hurriedly said.

"It makes sense, I'll take someone to a hotel for a while, and then the key over there will pass, and I'll let him control the scene."

Xu Dayuan nodded.

"Then go separately, you go to the hotel to have a look, I will meet that Zhang Forensic Doctor here, and talk to Sun Pengfei later, since we don't want to eat well, then everyone don't sleep, try Bai Qishan in the early morning, I think everything is because he was arrested."

This point was noncommittal, everyone moved, Zhou Ning called Da Zhao and Peng Shinian, and went to the dissection room together.

The corpse had been placed on the dissecting table, and the deceased's arms were slightly raised, his fingers were spread and slightly bent, and his legs were curled up, indicating that there was a stiff body.

"Assign work, Peng Shinian will make autopsy records for a while, Da Zhao is responsible for taking pictures, and I will be my assistant, you go and check the temperature outside at this time first, Peng Shinian will measure the rectal temperature of the deceased."

Saying that, the two of them moved, and Da Zhao's search speed was very fast.

"The temperature outside is now minus six degrees Celsius, and it can drop to zero degrees in the early morning."

"The deceased's rectal temperature was 36.1."

Zhou Ning nodded.

"Remove the clothes of the deceased and be careful of the knife in your chest."

The three of them cooperated, cut off the deceased's clothes and took them off, Zhou Ning stared at the deceased's chest, looking at the wound from the outside, the wound was a line, and the knife was tightly attached to the wound, but this angle was a little special, it was the handle of the knife downward, stabbing diagonally above the chest.

The deceased's teeth were very yellow, there were a lot of soft dirt in the gaps between the teeth, the left ear was pierced, and the three folds on the neck were all black dirt.

The fingernails were covered with black grease stains, and there was a strong smell between the legs.

Da Zhao hurriedly put on another mask.

"Hey, this person hasn't taken a bath for a few years, I said that the boxed lunch I ate every day before was sent by their family? Just the black oil in this nail, my God, I feel like my stomach hurts. ”

Peng Shinian retched, and Zhou Ning glanced at the two.

"Take samples from the mouth, nails, and rectum, if it's really disgusting and go out now, you two retching like this, I don't feel good either."

Da Zhao raised his hand and made a surrender with an apologetic face.

"I was wrong, I'll start sampling now, but the rectal temperature is not low, it's not long after I died."

Zhou Ning frowned.

"The temperature of the rectum is really a bit inconsistent with the zombie, theoretically speaking, the deceased can appear corpse morture half an hour after death, but his maintenance of this posture can be said to have been preliminarily fixed.

I think that after the death of the deceased, or rather the posture of the deceased being killed. It's the sitting position, it hasn't been changed at all, even if it moves, it's a slight movement, and it's been in the outdoor low temperature environment, and the speed of the zombie must be accelerated.

Especially this kind of heart stabbing but not bleeding profusely, either traumatic blood pericardium, or intrathoracic pulmonary hemorrhage, so that the occurrence of more severe mortis, according to the time you just measured, go back two hours, I estimate that the time of death of the deceased is around 18:20, or even a little earlier. ”

Da Zhao's eyes widened.

"So, the deceased died before the meal was delivered? No, he was already dead when he didn't come out of the hotel, didn't the people in the hotel find out? ”

Peng Shinian rubbed his chin and hurried over.

"We saw the monitoring just now, the person who delivered the food was wearing a hat and mask, tall and thin, and he looked at the figure of the deceased with a cold eye, not to mention that it really resembled the deceased, and acquaintances couldn't tell it if they didn't speak, maybe this person had been selected a long time ago, and I knew him before, and it was the kind in case of emergency.

I heard here that we arrested Bai Qishan, and so many people in Ganzhou, one by one, they were in a hurry, and I learned from our task force that we had ordered a meal, so we made this plan temporarily. ”

Da Zhao looked at Peng Shinian and nodded approvingly.

"Don't say that the poet's analysis is really reliable, but if it wasn't the poet who found the problem today, we dozens of people would have left it here, it's cyanide, I feel scared when I think about it."

Zhou Ning took a long breath and waved his hand at the two.

"Okay, destroy the corpse, place the dead, turn on the recording equipment, Peng Shinian is ready to record, Da Zhao will give me a scalpel."

Da Zhao clicked on the record button, and Zhou Ning briefly introduced the information of the deceased, as well as the discovery of the autopsy on the body surface, as well as the inference of the time of death, and then cut open the three chambers of the deceased.

The knife was carefully pulled out, Da Zhao measured the length and width of the knife, and the wound could be said to be almost exactly the same as the width of the knife, as for this knife, it was very similar to the boning knife used in the restaurant, only longer.

The handle of the knife is wrapped with adhesive tape, the blade of the knife has obvious grinding marks, the position of the junction between the blade and the handle, and the thick black oil, there is no brand mark on it, some places on the tape have been broken, and it has not been removed, but another layer is pasted, such an operation is more like the deceased, after all, he does not have high requirements for hygiene.

However, this piercing direction made Zhou Ning puzzled.

It stands to reason that when a person of the same height pierces the chest, it is a horizontal piercing, or the deceased is vertically pierced in a lying position, so that the maximum force can be exerted, so that the oblique penetration generally occurs when the height is unequal, and the murderer is shorter than the victim.

Why is that?
