Chapter 15: Self-production and self-sales?
Zhao Xinli came over quickly and took a photo of Zhou Ning with the scale next to him.
Zhou Ning stood up and walked out of the main house. Xu Dayuan saw him and hurried over. Zhou Ning actually wanted to take a breath. The protective mask only reduced the damage to the body from harmful substances in the corpse stench, but it would not block the stench.
"Mr. Xu, the male deceased had a gray-black mole behind his right ear, the size of a fingertip with hair on it. He was 172 centimeters tall. Judging from his clothing size, he weighed 130-140 kilograms, and wore size 39 shoes. He went shopping at Liqun Supermarket on October 18. Can you find the deceased's information this way?"
As he spoke, Zhou Ning showed the receipt in the evidence bag, and Xu Dayuan looked at it carefully through the bag.
"It's not realistic to go to the supermarket to check. There are so many people there. Even if we find him in the surveillance, we can't identify him. But this also shows that the deceased died after 15:23 on October 18. What time of death did you infer?"
Before Zhou Ning could say anything, the old detective came over, put on his reading glasses, and took a look at the photos in Zhou Ning's camera.
"Hiss, I think I've seen someone with this mole before."
After thinking about it, he slapped his thigh.
"I know this is Li Delin from Yujia Village next door. It seems that this man has set up some kind of company in the city. Wait for me to ask him."
Seeing the old detective go out, Xu Dayuan also breathed a sigh of relief. It would be good if he could find the deceased's information, which could save a lot of steps.
"Is there a time for death?"
Zhou Ning nodded. He had already figured this out.
"Based on the length of the maggots, the condition of the pupae, and the degree of decomposition of the body, I infer that the male deceased had been dead for 5-9 days. The deceased was chopped in front of the bedroom door and died lying on the door.
The deceased's shoes and pants were scattered, and she seemed to be in a hurry. This is all the information I have now. If Xu Dayao has no other instructions, I will continue to check the female deceased in the bedroom."
Xu Dayuan waved his hand. He was very satisfied with his subordinates who worked so hard.
Zhou Ning walked in quickly, checked the kitchen on the left side of the living room, and then came to the pool of blood at the bedroom door.
Zhao Xinli also followed him to the bedroom door, put down the survey mat, and Zhou Ning entered the bedroom. The room was surprisingly clean, without any unnecessary items. There was a bed, a wardrobe, and two single sofas.
There was no quilt or pillow on the bed, and there was not even a fold on the sheets. There was only an upside-down wooden chair in the middle of the bedroom, and a pair of red slippers, neatly placed.
There were obvious signs of incontinence on the chair and slippers, which is a very normal phenomenon for people who were hanged, especially women.
The house should have been renovated, but the main beam was relatively low and not covered by the ceiling. It was two meters from the ground, and the body was hung with a white cloth.
The deceased was barefoot, wearing a white shirt and black pants, and was neatly dressed. His short hair covered part of his face. His head was slightly drooping, and his tongue was not protruding. His abdomen was flat, but obvious corpse spots could be seen on his hands and feet.
Zhou Ning turned on the purple light and squatted down. There was not even a hair on the ground, but when he heard the sound of birds singing, Zhou Ning took a step back.
Only then did I discover that there was a small window two meters high on the north side of the living room with a tiny gap. No wonder there were so many flies, it seemed they came in from here.
However, why is there no screen on the window in such a clean room?
Zhou Ning didn't think much about it and went into the bedroom carrying the survey box, followed closely by Zhao Xinli.
As Zhou Ning put down the number sign, he took pictures from behind. After taking the pictures, Zhou Ning waved her hand.
"Send two men in to bring the dead man down."
Zhao Xinli went to call people. They were all heavily armed and wearing shoe covers. They cut the white cloth strips and put the deceased in a body bag on the stretcher. Then they went out and Zhao Xinli put the white cloth into the evidence bag.
Zhou Ning went forward and examined the body carefully. The rigor mortis was not serious. The rectal temperature was the same as the room temperature. The pupils could not see light. The U-shaped groove [1] on the neck was obvious. There were some bruises on the right cheek. He raised his hand to compare it. It should be a palm print, but it was smaller than Zhou Ning's hand.
There were only fly eggs on the edge of the groove, the inner corner of the eye, and behind the ear, but no maggots were found on the body.
By lifting the deceased's shirt, a network of corrupted veins could be seen on the abdomen, but the abdomen was not swollen. Based on these findings, the deceased died about 48-36 hours ago.
Zhao Xinli was standing next to them, snapping away non-stop.
Zhou Ning fell into deep thought. The scene was closed and the time of death of the two victims was obviously different.
No matter how you look at it, it seems like a case of self-production and self-sales [2], but if we analyze it in reverse, if it were a case of self-production and self-sales, the system would not be set up in this way.
If there was a murderer present, why did the woman die a few days later than the male victim?
Could it be that the murderer was living in the room with the female and male corpses?
But the room was locked from the inside and there were security nets on the windows. How did the murderer leave?
Thinking of this, Zhou Ning's eyes lit up.
I stood up and ran towards the living room, then looked up at the small window high up on the north side. Sure enough, there was no anti-theft net outside this window.
Walking closer to the window, there is a stove underneath, which should be used for heating. The stove is an environmentally friendly metal stove, and it is covered with tiles all around to form a large platform.
When illuminated by ultraviolet light, there was a trace of rubbing on the tile wall. It was not a shoe print, but seemed to be knitted fabric.
As Zhou Ning's eyes moved downward, a mark similar to footprints appeared, with some bloodstains on it. It was not a shoe print either. The person was wearing socks, stepping on the stove, then climbing up the north window and flipping out. However, due to the height limit, the window was not closed tightly.
"Xiao Zhou, forensic doctor, what did you find?"
Zhao Xinli followed over. After all, Zhou Ning's quick movements made people excited.
"Found a sock mark with blood on it, give me the measuring tape."
Zhao Xinli found a measuring tape in the survey box and handed it to Zhou Ning. Zhou Ning was 184 cm tall and stood on the edge of the stove close to the window, with his head just touching the ceiling.
After measuring, Zhou Ning grabbed a pen and wrote it on his survey suit. When the window was fully opened, the width, height, and diagonal sides were 33, 25, and 41 centimeters respectively, and the window was 158 centimeters away from the stove.
Zhou Ning stared at the window. He paused and waved his hand behind him. Zhao Xinli came over, raised his fat face and asked :
"What's wrong, Xiao Zhou, what do you want?"
"Magnifying glass, tweezers, evidence bag."
When Zhao Xinli heard Zhou Ning's words, he knew that he had found something. He happily took the thing and handed it to Zhou Ning on tiptoe.
Holding a magnifying glass, Zhou Ning looked carefully at the window and saw a row of eight glove fingerprints at the top.
Before he felt regretful, he saw two strands of hair floating on the edge of the window felt. Zhou Ning picked them up with tweezers, threw them into the evidence bag, and then handed them to Zhao Xinli.
"If you find hair with follicles, go outside the window and check if there are any footprints or other traces around. Also check for sticks or anything like that. After all, it's not easy for him to close the window at this height."
Zhao Xinli went there quickly and came back after a while shaking his head.
"There is a hardened road behind us. There are weeds in the gaps between the corners of the wall and the road. I didn't see any footprints or the wooden sticks you mentioned. However, there is a pile of firewood and a long bench used for decoration in front of the door of the house behind us."
He nodded and continued to look at the small window in front of him. It was not easy to climb up to this height with bare hands. At least one had to be thin, otherwise the window would be stuck.
After waiting for a while, there was no prompt from the system.
The analysis has reached this point, isn’t it still considered a preliminary analysis?
Following Zhou Ning's thoughts, the content of the intermediate task popped up. Based on the evidence at the scene, a preliminary analysis should be conducted to give the cause of death of the two deceased. The time limit was 60 minutes.
Oh, and the cause of death.
With a sigh, Zhou Ning jumped down.
"Take samples of the mop, broom, and water in the bucket. If there is any garbage, take it away. Also take photos of various places in the kitchen. I'll go find Xu Da and the others."
Zhao Xinli did not delay and quickly took the sampling bottle and left. When they entered the room, they all saw various cleaning tools placed at the kitchen door on the other side of the living room.
Zhou Ning didn't wait for Zhao Xinli and went straight out of the main house. He took off the isolation suit, gloves, hat and gas mask in front of the door and threw them all into a bag. He washed and disinfected his hands and smelled carefully. There seemed to be no stench of corpse. Then he walked to the gate of the courtyard, where Xu Dayuan and the others were standing.
Seeing Zhou Ning coming out, the old policeman also came over and rubbed his hands impatiently, but his tone carried a hint of instruction from a superior.
"How's it going, little comrade? You figured out something. Your master wasn't able to guide you. Don't worry. It doesn't matter if you can't find anything. Tell me if this is a case of self-production and self-sale."
Xu Dayuan didn't say anything, and it was unclear what his attitude was, but they had been investigating on the periphery for a while, and it was probably what the old policeman meant.
Zhou Ning was somewhat resistant. He was from the Forensic Office of the Criminal Police Brigade, and his direct supervisor was there. He looked at Xu Dayuan and shook his head firmly.
"After investigating the scene, we found a lot of traces, but I don't think this is a self-produced case. The murderer is someone else."
The old policeman obviously didn't believe it, and his expression was a little stiff. Just as he was about to speak, Xu Dayuan raised his hand to stop him.
"Don't be impatient. Tell me what you found."

PS:
[1] Groove: Groove is a groove-like mark formed by oppression on the neck. It is an important sign of strangulation and an important basis for determining strangulation.
The grooves are mostly located below the larynx, horizontally surrounding the neck in a closed state. There are usually 1 to 2 grooves, and the width is generally equivalent to the thickness of the rope. The depth is relatively consistent, and the pattern imprint of the rope can be seen on the surface.
[2] Self-production and self-sale: Self-production and self-sale is a slang commonly used in forensic medicine, which means killing someone and then committing suicide. The murderer created the crime and then eliminated the criminal. Because of the crime, the murderer was born, and because the murderer committed suicide, no one went to jail and the case was closed directly. Therefore, this is called the murderer's self-production and self-sale.
For forensic doctors, self-investigated cases are the most difficult. Because there is no confession from the victim, witnesses or suspect, the basis for the verdict is entirely based on criminal technology, and the requirements for evidence are the highest.
