Chapter 30 Can You Do This?
Squeezing the metal strip on the mask, Zhou Ning walked towards the north bedroom.

The two people have been living in this room for the past few days, and people from the port police station have also come in. Fingerprints and footprints on the ground are of little significance. It is better to look at the corpse first.

The second bedroom in the north is not big. There is only a 1.5-meter double bed and a bedside table in the room. There is nothing in the wardrobe. There is a small plastic bag next to the door. There are a few clothes, which are probably Song Luqing's things.

At this time, the mattress on the bed had been pulled to one side and stood against the wall.

There are old urine stains on the mattress, several large and small maps, exuding a strong smell, and there are grinding places on the four corners. Thinking that this is a rented house, it is estimated that this is provided by the landlord.

The wooden plank on the bed is a row frame, which is the bed plank with gaps. Through the gap, one can see that the position near the end of the bed is stuffed with a bunch of things. It can be distinguished that the wrapping is a green sheet with large flowers, and one arm slipped out of the sheet. When he came out, his bare hands were purple-black, and the nails were even more pitch-black.

Zhao Xinli leaned over at this moment, and took a look from Zhou Ning's side. He had seen the giant view before. Such a corpse state did not feel uncomfortable to him.

"Hehe, it's really stuffed under the bed, isn't he tall?"

Zhou Ning shook his head. He knew what Zhao Xinli meant. The 1.5-meter-wide bed was bundled horizontally, with neither side protruding.

"Looking at the shape, people are packed in a curled up state. Help me move the bed board and the four frames beside the bed?"

Zhao Xinli patted his chest.

"I'll find someone to do the physical work, you don't need to do it while you wait."

He turned around and went out, calling two policemen to come in for a moment, lifted the bed board slightly, and then removed the frame of the bed, leaving the head of the bed untouched.

Liu Fayi came in at this moment, lay at the door and saw the bundle on the north wall, and walked straight over.

"Don't look, hurry up and take pictures to fix the shape."

Zhou Ning hurried forward. With Doctor Liu there, he didn't feel too flustered and hasty. Following the position of Doctor Liu's fingers, he quickly cooperated to take pictures.

After observing it, the quilt wrapped around the body was tied with ropes in the upper, middle and lower parts, and the arm slipped out from the middle of the first and second knots.

Forensic Doctor Liu flicked the dead man's arm. The arm was not stiff, but swung slightly before he waved his hand.

"The body bag is ready, and the body will be carried into the body bag in a while. I will cut a rope and look at the face of the deceased first."

After a while, the body bag was delivered, and there was a flat cart underneath. Zhao Xinli squeezed over and cooperated with Zhou Ning to lift the body and put it in the body bag. During the lifting process, there was a stabbing sound near the head.

Zhou Ning put down the corpse, and then looked down. A fist-sized, dry blood stain appeared on the floor, which was small in size. Forensic Liu was stunned by this discovery.

"I'm careless, I still want to preserve the complete state, and take it back to the dissection room to see. Zhou Ning cut the rope with scissors, avoiding the knotted position."

Zhou Ning took the scissors and cut off the rope at the neck with all his strength. This green nylon rope doesn't look thick, but it took a lot of effort to cut it, which shows how strong this thing is.

Loosen the rope, and the wrapped sheet has been fixed in shape. Gently lift a corner, and the sheet is tightly wound. Forensic Liu took the scissors and cut several layers of the sheet.

As the left and right were lifted, the scene under the cloth sheet was revealed in front of the two of them.

Zhou Ning gasped, and Liu Forensic also shivered.

"Is it that exciting?"

I saw a plastic bag wrapped under the cloth sheet, the kind of plastic bag used for shopping in supermarkets. It can be seen that there are many layers, and there are newspapers inside, but the blood stains have been soaked and exposed from the gaps. Zhou Ning's heart rose. A bad feeling.

Fayi Liu paused, Xu Dayuan was in such a hurry, at least give him a direction after the investigation here, so that the investigation can be carried out.

"Go ahead and cut the bag, be careful!"

Zhou Ning held up the scissors, and began to cut the plastic bag from the side. There were three layers in total, and they were cut together. When they reached the top, they stopped. The traces of cuts all over the place appeared in front of his eyes.

One-third of the lip of the corpse had been lost, and the left teeth were exposed. The first and second molars on the lower left side were metal silver false crowns, and there were brown smoke and tea stains in the gaps between the teeth.

A green nylon rope is wrapped around the neck, and three loops have sunk deeply into the flesh of the neck, and the dark brown leathery [1] groove is obvious.

"The face was ruined. It seems that the wound was caused by multiple cuts with a knife. Either it was committed by an acquaintance, or it was a deep hatred."

Zhou Ning didn't speak, and looked carefully at the top of the dead man's head. There were not many gray hairs in the center of the head, and the hair around the head seemed a bit long.

Around the ears and neck, there are many brown spots. The skin is rough and peeling, very dark, but the bottom of the collar is very white. Could it be that the deceased worked outdoors?

As I was watching, the transparent display screen in front of me moved.

Zhou Ning knew that as long as there was a case, the system would start to work. Sure enough, familiar multiple-choice questions appeared on it.

Drop, the system releases the task, please bind the person to choose the difficulty of the task.

A. Primary tasks;

B. Intermediate tasks;

C. Advanced tasks.

Zhou Ning ignored it, and now his mind was on the corpse, thinking about choosing again later.

At this moment, Forensic Doctor Liu spoke.

"What are you doing in a daze? Measure the length of the corpse. Pay attention to the curled up legs. Just get an approximate value. When you're done, take the corpse away quickly. This state can't be checked here."

Zhou Ning nodded, quickly measured the length of the deceased, about 170 centimeters in height, forensic doctor Liu recorded it, and waved his hand directly.

"Okay, withdraw and withdraw."

Zhou Ning covered the mangled face with a plastic bag, pulled the body bag, and Zhao Xinli pulled the cart away. Just as Zhou Ning was about to turn around, the system beeped.

Drip, warning!

Drip, warning!

Drip, warning!

If the binding person does not make a choice within the specified time, the system defaults to the highest level task mode.

Zhou Ning paused.

If you don't talk about Wude, how can you still do this?

The difficulty of the mid-level task last time was increased. For this high-level task, let me live. I am a novice medical practitioner!

By default, the binding person has selected the advanced task, and now the task is released.

Advanced task content:

1. To find out the cause of death of the deceased, the task time is 6 hours;

2. To find out the identity of the deceased, the task time is 48 hours;

3. Find the murderer and find out the motive of the murder. The task time is 10 days.

Zhou Ning was speechless for a while, at the moment he didn't even have the strength to swear at others. Last time, for such a difficult case, the task time given was 72 hours. This time, he can directly give ten days, which shows the difficulty of this case.

Just as he was thinking, there was a pain in his foot, and Fayi Liu stared over.

"What are you doing in a daze? This is not the first scene. Apart from the blood oozing, there are no other traces. Let's go back to the autopsy. The face was chopped like this. It will be difficult to find the identity of the deceased."

Zhou Ning nodded, and walked out of the apartment building with the survey box, just as Xu Dayuan came over.

"What did the autopsy find?"

Zhou Ning shook his head, frowning.

"The face of the deceased was deliberately chopped up, and the face could not be seen. There is very little information available. The deceased was bald and gray-haired, with age spots on the back of the ears and neck. He was about 170 centimeters tall and estimated to be over 50 years old."

At this point, Forensic Doctor Liu came from behind, took off the gloves and mask, and signaled Zhou Ning to turn on the camera. Zhou Ning knew what Liu Yongxin meant, and he wanted Xu Dayuan to see the skin color and fingers of the deceased. This color is too representative .

"I found a photo of the neck and hands, that's right, the skin on the neck and arms of the deceased is very dark, the kind of marks left by the sun all year round, the nails are also very black, and there seems to be mud in the crevices of the fingerprints.

Detailed sampling and analysis needs to be done in the dissection room, but I speculate that the deceased may be a construction site worker, and the first and second molars on the lower left of the deceased are metal crowns, which are rarely used now because they are not as safe as porcelain, but The price is very cheap.

That's all there is to analyze, let's go back to the autopsy first, and be prepared, the identity of the deceased is not easy to find out. "

Xu Dayuan nodded and put his hand on Liu Fayi's shoulder.

"Let's go back, give me the autopsy information as soon as possible. I have no direction at all here. The surveillance of the community has been copied, but the north wall of the community is not closed, and the surveillance is not clear. I will ask someone to check the surrounding construction sites. gone."

Forensic Liu sighed.

"It's hard, let's take one step at a time!"

【1】Leather-like:
When the human body is in living conditions, every organ and tissue in the whole body contains a certain amount of water.After the death of the human body, the ability to absorb water is lost, the blood circulation stops, and the water lost by evaporation cannot be replenished. The water evaporates rapidly from the thinner skin of the corpse and the skin peeling off, and the local dryness is waxy yellow, yellowish brown or dark brown. , the texture becomes hard, which is called parchment-like transformation, also known as local desiccation.

Leatherization can make chafing more noticeable.Wounds, cord grooves, epidermis exfoliation, etc. that were injured during life will dry out shortly after death and make them appear more clearly.A similar dryness can also result from exfoliation of the epidermis that occurs shortly after death.However, the leathery appearance after death is lighter in color, and life reactions such as bleeding are absent.
