"Good leader, I'll look it up according to this information."

"Don't be in a hurry to hang up the phone. From now on, your diet should be eaten with the staff of the local bureau. You can't go out alone, especially you can't eat or drink food that is given at will. We found poisoning here, so please stop. , work quickly."

Xu Dayuan hung up the phone, probably He Chunyang was in a daze at this time.

At this moment, Lao Liang and a few people from the cafeteria brought up a large pile of thermos bottles, rubbed their hands with guilt, and clasped their hands together towards Xu Dayuan.

"I'm sorry Bureau Xu, if the gas stove in the canteen wasn't broken today, I wouldn't be able to order food outside, let alone poisoning, it's all my problem."

Xu Dayuan waved his hand.

"It's okay, go with two people and follow Lao Liang to look at the gas stove. Don't ignite it lightly. First open the doors and windows to ventilate, and then go in with a flashlight to check. Don't ignite lightly. Just check whether there is any problem with the pipeline. If you find anything, seal it up immediately."

When the few people went out, Da Zhao distributed instant noodles and ham sausage to everyone. Everyone was having fun, and there was no complaint. After all, everyone was hungry. Zhou Ning finished eating quickly. Seeing Xia Momo poking him, he looked down and found Xia Momo Momo handed over a marinated egg, Zhou Ning smiled and shook his head.

"Go ahead and eat. After eating, follow Zhu Xingxing and the others back to the hotel. Tonight we will be interrogated overnight."

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

"I won't hold you back, but this is going to be eaten."

After finishing speaking, Xia Momo sat with Zhu Xingxing and the others. Zhu Xingxing comforted Zou Jialong all the time. After all, he was responsible for receiving the boxed lunch, so it was inevitable that he blamed himself.

Da Zhao gave Zhu Xingxing a wink, Zhu Xingxing got up quickly, Da Zhao walked up to him, and said in a low voice:
"Several meanings, what problem can self-blame solve? Is it possible to catch the murderer who poisoned me, or can it promote the investigation of the case? If it is useful, I will blame myself with you. Of course, if you can't adjust such problems emotional, then simply go back to Qindao."

Zou Jialong was startled, and quickly waved at Da Zhao.

"Brother Zhao, I have no other intentions."

Zhao Xinli waved his hand.

"Stop talking nonsense, take all the inside of the lunch box, take samples and save them for freezing, mark them clearly for me, and collect fingerprints and DNA on the outside of the box lunch, it's not good for someone to send us questions, can you do it?"

"Yes, we'll go right away."

Speaking of which, 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 laughed happily and struggled towards his double-ingredient instant noodles. There was no soup left in a moment.

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

Xu Dayuan felt cold, and waved his hands towards Zhou Ning and Da Zhao.

"You two go and have a look. It is estimated that the driver who delivered the meal has been silenced. Let's see if there are any clues found on the body."

Zhou Ning nodded and glanced at Xiao Qu.

"I'll go for an autopsy. You can use the software to make an accurate inference. The height, weight, and behavioral characteristics of the food delivery driver will be sent to me later."

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

"You take the bus back to the hotel with Momo Xia. You are not needed here. Come over early tomorrow morning to take over the work. Tonight we can't keep up with everyone."

Zhu Xingxing nodded, and dragged Xia Momo and the others away.

Zhou Ning came to the dissecting room, followed by Peng Shinian and Da Zhao. As expected, Tao Zhenshan and the others were already carrying the wooden plank inside. When they saw Zhou Ning, they spat on the ground.

"It was late, and it seemed that someone had silenced him. He stabbed the heart with a knife, which was quite professional, and the knife was not pulled out. I looked at the back of the corpse, and the tip of the knife was almost pierced through.

The car door was open, the car key was inserted in the keyhole, and the body was in the driver's seat, but there was blood on the side of the co-pilot. I suspect that the deceased was killed while sitting in the co-pilot's seat, and his mobile phone and wallet were gone, and the glove box was also opened. Then, the scene was disguised as a robbery. "

Zhou Ning glanced at the corpse, and stretched out his hand to lift off the 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 a knife blade. The head and eyelids are slightly opened, the mouth is slightly opened, and the hands and fingers are bent, as if they are about to grasp, but they are only slightly raised.

"Let me take a look. I will conduct an autopsy immediately and give you the results. Does the deceased Yunliangang have any relatives?"

"I haven't checked it yet. I'll check the household registration information later."

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

"If you have any ideas, just say it."

"It's only after eight o'clock. The deceased delivered the food to the Public Security Bureau at 19:10. The time to go out would be earlier. The food delivery is just across the road. No one has been back for so long. Is there no one to find the owner of the restaurant?"

Tao Zhenshan and Xu Dayuan looked at each other and said quickly.

"It makes sense. I'll take someone to a restaurant in a while. Now that the key is over there, I'll ask him to control the scene."

Xu Dayuan nodded.

"Then split up and go to the restaurant to have a look. I will meet that forensic doctor Zhang here first, and I will talk to Sun Pengfei later. Since we are not allowed to have a good meal, everyone should not sleep. Bai Qishan will be interrogated in the early morning. I think it's all because of him being caught."

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. The deceased's arms were slightly raised, his fingers were stretched and slightly bent, and his legs were also curled up. This posture indicated that rigor rigor had already occurred.

"Assign the work. Peng Shinian will make autopsy records later, and Da Zhao will take pictures and be my assistant. You go to check the temperature outside at this time, and Peng Shinian will measure the rectal temperature of the deceased."

As the two moved, Da Zhao searched very quickly.

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

"The deceased's rectal temperature was 36.1."

Zhou Ning nodded.

"Take off the clothes of the deceased, and be careful of the knife on the chest."

The three of them worked together to cut off the deceased's clothes. Zhou Ning stared at the deceased's chest. The wound looked like a line on the outside, and the knife was tightly attached to the wound. However, this angle was a bit special, with the handle of the knife facing downwards, facing obliquely above the chest cavity. pierced.

The deceased's teeth were very yellow, there was a lot of food residue and soft dirt between the teeth, the left ear was pierced, and the three folds of the neck were covered with black dirt. Zhou Ning was a little surprised to see this, it seems that tramps rarely see it So much dirt.

The nails were covered with black oil stains, and there was a strong foul smell between the legs.

Da Zhao hurriedly put on another mask.

"Uh, this person hasn't showered for several years. Did I say that the box lunch I ate every day was sent by their family? It's just the black oil in the nails. Oh my god, I seem to have a stomachache."

Peng Shinian retched in cooperation, Zhou Ning glanced at the two of them.

"Take samples from the mouth, nails, and rectum. If you are really sick, go out now. I don't feel good when you two retch like this."

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

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

Zhou Ning frowned.

"The rectal temperature is really inconsistent with the rigor. Theoretically speaking, rigor can appear half an hour after the death of the deceased, but the maintenance of his posture can be said to have been initially fixed.

In my opinion, after the death of the deceased, or the posture of the deceased being killed.It is the sitting posture, which has not been changed at all, and even if it is moved, it is a slight movement. The speed of rigor must be accelerated in the low temperature outdoor environment.

Especially when the heart is stabbed, but there is no massive bleeding, it is either traumatic hemopericardium or intrathoracic and intrapulmonary hemorrhage. This kind of severe rigor occurs. According to the time you just measured, go back two hours. I estimate the death time of the deceased. Around 18:20, maybe even a little earlier. "

Big Zhao stared wide-eyed.

"So, the deceased died before the food was delivered? No, he died before he came out of the restaurant. Didn't the people in the restaurant find out?"

Peng Shinian rubbed her chin, and hurried over.

"Just now we saw the surveillance. The person who delivered the food was wearing a hat and a mask. He was tall and thin. He looked coldly at the body shape of the deceased, let alone the deceased. He couldn't tell the difference even if he didn't speak. Maybe this person It was chosen a long time ago, and I knew it before, just in case of a rainy day.

I heard that we captured Baiqi Mountain and so many people in Ganzhou, everyone was in a hurry, and I learned from our special case team that we had ordered a meal, so I made this plan impromptu, I feel that time is short , These people are absolutely amazing to be able to respond so quickly. "

Da Zhao looked at Peng Shinian and nodded in approval.

"Not to mention the poet's analysis, it's really reliable, but if the poet didn't find the problem today, dozens of us would be left here. It's cyanide. I feel scared after thinking about it."

Zhou Ning let out a long breath and waved towards the two of them.

"Okay, destroy the rigor, arrange the deceased, turn on the recording equipment, Peng Shinian is ready to record, and Da Zhao will give me the scalpel."

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

The knife was pulled out even more carefully. Da Zhao measured the length and width of the knife. The wound can be said to be almost exactly the same as the width of the knife. As for this knife, it is similar to the boning knife used in restaurants, only longer.

The handle of the knife is wrapped with adhesive tape, and the blade body has obvious grinding marks. There is thick black oil stain at the junction of the blade body and the handle. There is no brand mark on it. Some parts of the adhesive tape have been broken and have not been removed , but to paste another layer, this kind of operation is more like what the deceased did, after all, he does not have high requirements for hygiene.

However, Zhou Ning has been puzzled by this stabbing direction.

It stands to reason that when people of the same height stab into the chest, they do so horizontally, or vertically when the deceased is lying down, so that the force can be maximized. Such oblique stabbing usually occurs when the heights are unequal. The murderer was shorter than the victim.

what is this?
