novice forensic medicine

Chapter 15 Self-produced and sold?
Zhao Xinli hurried over, put Zhou Ning on the scale next to him, and took pictures together.

Zhou Ning stood up and stepped out of the main house. Xu Dayuan saw that Zhou Ning hurried over. Zhou Ning actually wanted to catch his breath. The protective mask only reduces the damage to the body caused by the harmful substances in the body odor, and the smell will not be blocked.

"Xu Da, the male deceased had a gray-black mole behind his ear on his right side, the size of his fingertips and hair on his face, and his height was 172 cm. According to the size of his clothes and pants, his estimated weight was 130-140 catties, and his shoes were size 39. He went there on October 10. Go shopping in Liqun Supermarket, can you see if you can find the information of the deceased?"

Speaking of which, Zhou Ning showed the receipt in the evidence bag, and Xu Dayuan took a closer look through the bag.

"It's unrealistic to go to the supermarket to check. There are many people who go there. Even if it is found in the surveillance, it is impossible to identify the identity. But this also shows that the deceased died after 10:18 on October 15. Did you infer the time of death?"

Before Zhou Ning could speak, the old detective came over, put on his glasses, and glanced at the photos in Zhou Ning's camera.

"Hiss, I seem to have seen someone with this mole."

After thinking about it, he patted his thigh.

"I know this is Li Delin from Yujia Village next door. It seems that this person has set up some kind of company in the city. Wait for me to ask."

Seeing the old detective go out, Xu Dayuan also breathed a sigh of relief, as long as he can find the information of the deceased, it can save a lot of steps.

"Is it time to die?"

Zhou Ning nodded, he just ignored this.

"Based on the length of the maggots, the condition of the pupae, and the degree of corruption of the corpse, I deduce that the dead male died within 5 to 9 days. The deceased was chopped in front of the bedroom door and lay down to die at the door.

The deceased's shoes and pants were scattered, which seemed to be in a hurry. There was only so much information available. If Xu Da had no other orders, I continued to check the female deceased in the bedroom. "

Xu Dayuan waved his hand, Xu Dayuan was very satisfied with such an active subordinate.

Zhou Ning stepped in quickly, checked the kitchen on the left of the living room, and then came to the pool of blood at the door of the bedroom.

Zhao Xinli also followed to the door of the bedroom, put the survey board on it, and Zhou Ning entered the bedroom. The room was surprisingly clean, and there were no extra items. There was a bed, a wardrobe, and two single sofas.

There were no quilts or pillows on the bed, and there was not even a pleat on the sheets. There was only a wooden chair upside down in the center of the bedroom, and a pair of red slippers, neatly arranged.

It's just that there are obvious traces of fecal incontinence on the chair and slippers. This phenomenon is normal for hanged people, especially for women.

The house should have been redecorated, but the main girder was relatively low and was not wrapped in the ceiling. It was two meters away from the ground, and the corpse was hung on a strip of white cloth.

The deceased was barefoot, in white clothes and black trousers, neatly dressed, with short ear-length hair covering part of his face, his head drooping slightly, no tongue protruding out, and a flat abdomen, except for obvious corpse spots on his hands and feet.

Zhou Ning turned on the purple light, 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.

It was only then that I discovered that there was a small window at a height of two meters on the north side of the living room, with a small gap open. No wonder there were so many flies, and it seemed that they came in from here.

However, in such a clean room, why didn't the screens be drawn?
Zhou Ning didn't think much, and entered the bedroom with the survey box, followed by Zhao Xinli.

As Zhou Ning put up the number sign, he clicked and took a picture behind him, and Zhou Ning waved his hand after taking the picture.

"Call two men in and put the dead down."

Zhao Xinli went to call people, each of them was very armed, wearing shoe covers, cut off the white cloth strips, put the deceased in the body bag on the stretcher, and then went out, Zhao Xinli put the white cloth into an evidence bag.

Zhou Ning went forward to check it carefully. Rigidity was not serious. The rectal temperature was the same as room temperature, the pupils could not transmit light, the U-shaped groove [1] on the neck was obvious, and there were some bruises on the right cheek. Compared with the above, it should be a palm print, but it is smaller than Zhou Ning's hand.

Only fly eggs were found on the edge of the legou, the inner corner of the eye, and behind the ear, and no maggots were found on the body.

When the deceased’s shirt was lifted, a network of corrupt veins could be seen in the abdomen, but the abdomen was not enlarged. According to these findings, the death time of the deceased was around 48-36 hours.

Zhao Xinli was beside him, clicking non-stop.

Zhou Ning fell into deep thought. The scene was sealed, and the time of death of the two deceased was obviously different.

No matter how you look at it, it looks like a case of self-produced and self-marketed [2], but if it is a case of self-produced and self-marketed, the system will not set it like this.

If the murderer was present, why did the woman die a few days later than the man?
Could it be that the murderer lived in the room with the corpses of the woman and the dead man?

But the inside of the room is locked, and there are anti-theft nets on the windows. How did the murderer leave?
Thinking of this, Zhou Ning's eyes lit up.

He got up and ran towards the living room, rushed to the living room and looked up at the small window on the north side. Sure enough, there was no anti-theft net outside the window.

Going to the window, there is a stove below here, which should be used for heating. The stove is an environmentally friendly metal stove, and tiles are pasted around to make a huge platform.

Illuminated by a purple light, there is a trace of rubbing on the tiled wall, not a shoe print, it seems to be knitted fabric.

As Zhou Ning looked down, a trace similar to footprints appeared, with some rubbed blood on it, and it was not a shoe print, but wearing socks, stepping on the stove, then climbing up the north window, turning out, just the height Restricted, so the window is not closed tightly.

"Forensic doctor Xiao Zhou, what did you find?"

Zhao Xinli followed. After all, Zhou Ning's quick movements made people excited.

"Find a sock imprint with blood on it, give me the tape measure."

Zhao Xinli found the tape measure in the survey box and handed it to Zhou Ning. Zhou Ning was 184 cm tall, standing on the edge of the pot and approaching the window, with his head just touching the roof of the shed.

After the measurement, Zhou Ning grabbed a pen and recorded on the survey suit that the width, height, and diagonal sides of a window were 33, 25, and 41 cm when fully opened, and the distance from the window to the stove was 158 cm.

Zhou Ning stared at the window, his movements paused, and he waved his hands behind him. Zhao Xinli leaned over, raised his fat face and asked in confusion:

"What's the matter, Xiao Zhou Forensic Doctor, what do you want?"

"Magnifying glass, tweezers, evidence bag."

When Zhao Xinli heard Zhou Ning's words, he knew what he had found, so he fetched something in a hurry, and handed it to Zhou Ning on tiptoe.

Holding a magnifying glass, Zhou Ning observed carefully on the window, and there was a row of eight glove fingerprints on the top.

Before he felt sorry, he saw two strands of Cunxu's hair fluttering on the edge of the window felt. Zhou Ning picked them up with tweezers, threw them in the evidence bag, and handed them to Zhao Xinli.

"If you find hair with hair follicles, go out of the window and see if there are any traces of footprints around. Oh, and search with a stick. After all, it is not easy for him to close the window at this height."

Zhao Xinli hurried over and came back shaking his head for a while.

"Behind is the hardened road. There are weeds in the gap between the corner and the road. I didn't see footprints, or the wooden sticks you mentioned, but there is a lot of firewood piled up in front of the door of the house behind, and there are long decorations. Horse stool."

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, the system did not prompt.

It has been analyzed to this point, isn't it considered a preliminary analysis?

Following Zhou Ning's thoughts, the content of the intermediate task jumped out. According to the evidence at the scene, a preliminary analysis was performed to give the cause of death of the two deceased, and the time limit was 60 minutes.

Oh, yes, and the cause of death.

With a sigh, Zhou Ning jumped down.

"Sample the water in the mop, broom, and bucket. If there is any garbage, take it away, and take pictures everywhere in the kitchen. I will go to Xu Da and the others."

Zhao Xinli didn't delay, and hurried away with the sampling bottle. When they entered the door, they all saw that there were various cleaning tools on the door of the kitchen on the other side of the living room.

Zhou Ning didn't wait for Zhao Xinli, and went out of the main house directly, took off the isolation suit on his body in front of the door, and threw the gloves, hat and gas mask into a bag, cleaned and disinfected his hands, and smelled carefully, it seemed that there was no smell of corpses , and then came to the gate of the courtyard, Xu Dayuan and the others were all standing here.

Seeing Zhou Ning coming out, the old policeman also came over and rubbed his hands impatiently, but his tone was a little bit like being pointed out by a superior.

"What about you little comrade, you can see something, your master has not been able to bring you, don't worry, it doesn't matter if you can't find anything, tell me if it is a case of self-produced and sold?"

Xu Dayuan didn't speak, and it's hard to tell what his attitude is, but they have been investigating for a while, and it is estimated that this is what the old policeman meant.

Zhou Ning was somewhat conflicted. He was a member of the Forensic Office of the Criminal Police Brigade, and his immediate leader was there. He looked at Xu Dayuan and shook his head firmly.

"After on-site investigation, many traces were found, but I don't think this is a case of self-produced and self-sold, and the murderer is someone else."

The old policeman obviously didn't believe it, his face was a little stiff, just about to speak, Xu Dayuan raised his hand to stop him.

"Don't worry, tell me what you found."

PS:
[1] Legou: Legou is the groove-like mark formed by the oppression of the neck by extortion. It is an important sign of strangulation and an important basis for determining strangulation.

Le grooves are mostly located below the throat, horizontally surrounding the neck, and are in a closed state. There are 12 or more of them. The width is generally equivalent to the thickness of the ransom.

[2] Self-produced and self-marketed: Self-produced and self-marketed is a slang term commonly used in forensic medicine, which means to kill someone and then commit suicide.The murderer produces a crime, and finally the criminal is eliminated. Because of the crime, a murderer is born, and because the murderer commits suicide, no one goes to jail, and the case is closed directly.

For forensics, the cases of self-produced and self-marketed products are the most difficult.Because there are no confessions from victims, witnesses or criminal suspects, the basis for finalizing a case depends entirely on criminal technology, and the requirements for evidence are the highest.
