How to describe the smell of corpses?

This taste is similar to the comprehensive taste of stinky salted fish + rotten eggs + rotten meat, which is thrown into the dry toilet and fermented for two days.

Xu Dayuan and those people from the Tieshan Police Station all looked at Zhou Ning, even if it was disgusting at this time, Zhou Ning couldn't be cowardly, after all, Xu Dayuan scolded Cheng Li's mother so hard just now, he couldn't embarrass Xu Dayuan no matter what.

Zhou Ning didn't speak, just nodded at Xu Dayuan, then put down the big bag behind him, squatted on the ground and took out the contents inside, Zhao Xinli put down the survey box and rubbed his nose.

"What does it smell like?"

"Corpse stench."

Zhao Xinli was stunned and swallowed back the second half of the sentence he was about to say.

"Well, I'm waiting for you here."

Zhou Ning can't say anything else, with his peers watching, he won't complain now, after all, he is a forensic doctor.

Find the isolation gown and the gas mask and arm yourself.

Walking quickly to the door, a wooden door was tightly closed, and with a slight push, a lock with a key in the door shook and made a crisp sound.

The room was locked from the inside, and he looked back at Zhao Xinli.

"Help me get my fingerprints on the door, and then pry the glass open without breaking the lock, that's fine, right?"

Zhao Xinli nodded, put on gloves, carried a brush and black powder for collecting fingerprints, evenly brushed the black powder on the door, and then scanned and found seven incomplete fingerprints.

After taking the fingerprints and throwing the things in the physical evidence bag of the investigation box, the putty on the edge of the glass was carefully peeled off, the nails were cleaned off, and the glass fell down with tape.

Slipped through the glass gap, twisted the key to the copper-colored three-ring lock, threw it into the evidence bag, and with a gentle push, the door opened.

At this time, Zhou Ning had already put on three layers of gloves, goggles, gas masks, isolation suits, everything was armed, and he picked up the survey box and walked to the front of the main house.

Conan's favorite room.

Zhou Ning took a deep breath and shook off the messy thoughts.

A male corpse with white flowers on his lower body broke into Zhou Ning's sight like this, with a knife stuck in the back of his heart, pools of blood, blood droplets, and blood stains on the ground that rubbed the layers all over the place, and the flies on his body rose and fell, and some milky maggots [1] wriggled on his body.

Zhou Ning's hairs stood on end, and the feeling of nausea made him feel even more hypoxic.

However, this time should not be cowardly.

Stepping in, Xu Dayuan and they had already come to the door, how many pairs of eyes were staring at Zhou Ning's movements, and the old policeman who was chatting with Xu Dayuan raised his chin towards Xu Dayuan.

"You can prepare these things before you come, it seems to be a professional, when did you pick up the treasure?"

Xu Dayuan looked indifferent, put on a mask, and hugged his arms.

"Professional, Xiao Zhou's forensic doctor is from a professional class, and the last 9.27 case was able to catch the suspect within 24 hours, which is his credit."

The old policeman had surprise on his face, and the two continued to talk in a low voice.

Such praise did not bring Zhou Ning any excitement, but added a little more pressure.

Finding a clean place and putting down the survey box, Zhou Ning began to take pictures of various parts, and measured the height of the deceased and the size of each part.

The deceased's left arm was stretched out towards the door, his right hand was curled up at the side of his head, he was wearing a white half-sleeved T-shirt on his upper body, and he was not wearing anything on his lower body, and there were two sneakers scattered not far from the body, the heels of the shoes were crumbled, and near the bedroom door, there were clothes scattered on the ground, and next to it was another pool of blood.

The deceased's face was tilted to the right, his mouth was open, his tongue was protruding, his eyes were protruding, his entire face and facial features were already swollen, and there was a cut on his neck, where a part of maggots had gathered, and part of his skin had been eaten by maggots.

Zhou Ning's gaze ignored the maggots and flies, and the state of the deceased, as if it had been scanned, had already appeared on the transparent screen in front of him.

At the same time, a familiar sound appeared in Zhou Ning's ears.

Dr, the system publishes the task, please bind the person to select the task difficulty, A. beginner task, B. intermediate task, C. advanced task.

Zhou Ning is stupid, is it all playing like this now?

The three difficulty levels are obviously the highest and most difficult to complete, and of course the rewards are also increased accordingly, but he still has self-knowledge of a few pounds and taels.

High rotting corpse, if you want to find evidence, the difficulty is not a little high, but thinking of the corresponding reward, Zhou Ning is a little itchy in his heart, or if he is not modest, he will select the intermediate task?

I was still thinking in my head, and there was a sound in my ears, and the content on the screen had changed.

The binder selects an intermediate task, and now the task is released.

Intermediate Task Content:

1. According to the evidence at the scene, conduct a preliminary analysis and give the cause of death of the two deceased, with a time limit of 60 minutes.

2. Find the murderer, as well as all the evidence, within 72 hours.

Rewards:

When one of the intermediate tasks is completed alone, and the other is not completed, there will be no rewards and punishments, and the timeout meter will be invalidly submitted; Both tasks are completed within the specified time, and corresponding rewards will be drawn according to the quality of completion and the remaining time.

Zhou Ning was completely stunned, 10,000 crows flew overhead, this is a special intermediate task?

I thank you, it's not like I'm alone, doing the work of a police force, you killed me.

System Warning!

If the binder abandons the task, all the rewards obtained from the system will be withdrawn.

Zhou Ning was stunned.

Wrong teeth, take two sharp breaths, and accept the task!

Drop, the countdown begins!

With a bang, two countdown signs appeared above the big screen, one was 00:59 and the other was 71:59.

This......

How is this still overlapping timekeeping, an hour is so calculated?

With a sigh, Zhou Ning stood up and waved his hand at Zhao Xinli outside the door, if you want to find a helper, you can investigate it yourself, and it will take more than an hour to finish it.

Zhao Xinli covered his mask, put on his shoe covers, carefully avoided the blood on the ground step by step, and approached, looking at Zhou Ning angrily.

"What's wrong, Forensic Doctor Xiao Zhou?"

Zhou Ning didn't talk nonsense, stuffed the camera into his arms, and threw him a mask.

"Wear two layers of masks, which can block a little smell, and then follow my movements, I put down the sign and let you take pictures, you can take pictures, I can't finish it until noon, we still have to investigate the scene as soon as possible, and then transport the body away."

Zhao Xinli wanted to shirk it, Xu Dayuan in the back coughed, Zhao Xinli trembled, and honestly took the camera and mask like a quail, and armed himself.

"Come on, I'll do your bidding."

Xu Dayuan pulled the old policeman away at this time, and Zhou Ning only heard part of Xu Dayuan's words.

"Let's go, let's investigate the periphery, the people from the village committee called, and then called the stupid neighbor to ask, it's best to check if there are people around who have installed monitoring at home, and pick the kind of people with cars to check ......"

Zhou Ning held a stack of signs with numbers, and placed the pools of blood, blood droplets, wipe-like blood stains [2], and bloody footprints on the ground in turn, and of course, the clothes and shoes of the male deceased were also placed.

Then waved his hand, and Zhao Xinli went over to take pictures.

Zhou Ning bent down and rummaged through his pockets for clothes and shoes, and there was only one shopping receipt from Liqun, which was put into the physical evidence bag.

Then use tweezers to pick up a few pupa, this pupa is big and small, the color is light brown shell is not very hard, Zhou Ning raised his eyes to observe, the flies flying on the corpse are ordinary house flies, and there are also mung bean flies, the scientific name is mercerized green flies.

Looking at the wriggling maggots, Zhou Ning endured the nausea, picked up a relatively fat and robust one, measured it with a ruler, the length was 13 mm, found the smaller ones, measured a few, the length was 10 mm, 11 mm, and 12 mm.

His mind raced back to the part of the scene investigation about insects and the time of death.

Maggots appear, 10-20 hours after the death of the deceased, flies grow at a rate of 2-3 mm per day, as for the appearance of fly pupae, they generally appear in 5-7 days.

Zhou Ning squatted and moved two steps, the face of the male deceased was already seriously deformed, he stretched out his hand, wanting to push the deceased's head, so that he could see the full appearance of the face, but as soon as he touched his forehead, the soft and collapsed touch as if it was about to melt, made him give up this action.

But with such a move, the flies on the deceased's neck flew up, and where the hair behind the deceased's ear and his chin met, there was a mole the size of a finger with a few hairs on it.

Zhou Ning was overjoyed in his heart, and looked up to search for Zhao Xinli's figure.

"Hurry up and take pictures!"

......

PS：

[1] Flies and maggots: In forensic entomology, the morphology of flies at various stages can be used to infer the time of death of the deceased, so maggots in the scene are also very important. (disgusting though)

The eggs develop into larvae after one day, and then develop into a first-instar worm that frantically eats the corpse after another day, becomes a second-instar worm after a day, then feeds frantically for one day and becomes a third-instar worm, pupates after four to six days, and pupates five days later, and the adult breaks the shell.

According to the test, it takes 19 days for the eggs to develop into adults when the indoor temperature is 22 degrees Celsius, and 12 days if the temperature is above 25 degrees Celsius. Death time = fly egg-laying time + fly egg hatching time + maggot growth time.

The length of maggots when they break eggs is about 0.175 cm. When the temperature is higher than 25 degrees Celsius with the same temperature and sufficient food, the coefficient of variation between the growth time of maggots and the length of maggots is about 85 hours per centimeter.

[2] Wipe bloodstains: refers to the bloodstains formed by the bloodstained object directly in contact with the carrier and left on the carrier by smearing, rubbing, touching, rubbing and other movements.

For example, blood-stained hair is often wiped to form cord-like blood stains, and blood-stained fingers are often wiped to form flaky (rubbing), lumpy (touching), dotted (grasping) and long (dragging) bloodstains.

The way in which the bloodstains formed by writing or drawing after the hands or other objects are stained with blood still belongs to the category of wipe-like bloodstains, so we use them as a more special type of wipe-like bloodstains.
