There is a mountain on the outskirts of the city that has no name, but the scenery of the mountain is not bad, there are chestnut forests, there are small streams, there are more people coming, and gradually it is also famous, everyone calls it Chestnut Mountain. Pen ~ fun ~ pavilion www.biquge.info

Catching up with the May Day holiday, many people came to Lishan for hiking, and people came and went, but only one group of people saw things that should not be seen.

Guan Zheng dragged Xu Jiuyan up the mountain, and the crowd of onlookers was crowded around the yellow cordon on a small hillside, Guan Zheng took out his pockets several times, and finally said embarrassedly: "I didn't bring my police ID, can I brush my face?" ”

Xu Jiuyan held her forehead, handed her police officer card to the police officer with an unknown face, and said, "Captain of the Criminal Police Brigade." ”

"Oh oh oh, Masa, right?"

Guan Zheng smiled proudly and said, "Well, it's me." ”

"Oh mom, I finally saw it alive."

How can this guy say that, like a comedian. Guan Zheng patted the police officer on the shoulder and said, "What, I'll brush my face in the future." ”

After speaking, Guan Zheng had already hurriedly entered the scene. Guan Zheng complained and said: "Why didn't you tell me to remember to bring a police officer ID before leaving?" ”

"Who knew you didn't bring it? Can you grow a snack in the future? ”

Guan Zhengdao: "Are these things serious? The case is more important, right? ”

For a long time, Yan skimmed him and didn't speak.

Before she got closer, Xu Jiuyan began to protest: "Oh my God. What is it? So stinky? ”

"It's a corpse stench. At room temperature, 3~6 hours after death, the spoilage bacteria in the intestine multiply and grow, and begin to produce putrefactive gas, releasing a putrid odor, which is called corpse odor. In addition to oxygen, nitrogen, hydrogen, carbon dioxide, and methane, putrefactive gases also contain components with strong odors, such as ammonia and hydrogen sulfide.

Due to the production of a large amount of putrefactive gas, the colon is first highly inflated, and the upper intestine is expanded, and the abdomen is highly distended and raised. The smell of corpses overflowed from the mouth, nose, and ****. The smell of corpses is mainly the smell of putrescine and cadaverine. ”

The small circle shouted from afar: "Who grabbed my lines?" ”

Guan Zheng smiled and said, "Anyway, I'm also a student biologist, so I still understand this." ”

Xiao Quan spread his hands and said, "Okay, I'll go on, cadaverine is a compound with a rancid odor produced by protein hydrolysis when animal body tissues decay, it is a slurry liquid at room temperature, and it can be coagulated and crystallized by deep freezing. Cadaverine fumes in the air and can form dihydrate.

Furescine is an organic compound that is a colorless crystal or colorless to yellowish liquid at room temperature. Like cadaverine, putrescine is produced by the amino acid degradation of proteins in living organisms or corpses.

The smell of highly decaying corpses will remain on the body for several days and cannot be washed off, and it can be smelled at the scene regardless of the protective measures. So, comrades, I'm probably going to stink for the next week. ”

"It's okay, Yoko doesn't dislike you!"

"Huh? Who called me? ”

Guan Zheng smiled and said, "How is it? Did you find anything? ”

"It's all maggots, and they're still wriggling." After Li Chongyang finished speaking, he turned around and vomited.

Guan Zheng said jokingly: "Haha, this time it's your turn to be happy?" Is it a small circle? ”

"Fuck you, I'll calm down first."

Guan Zheng walked over, picked up a white maggot from the pile of white bones with the tweezers in Xiaohuan'er's hand, and showed it to Xu Jiuyan, who hid far away and said, "Don't come here!" Disgusting to death! ”

"Oh, it's okay, at least you don't throw up. That buddy, I've been doing it for several years, and I still vomit when I see this thing, and I'm going to invite him to eat boiled pork belly tonight. ”

"What is boiled pork belly?"

"It's that kind of pork belly, cut into shreds, rinsed, cooked, white and super tender, long and short, and even smells like that thing, and the nutritional value is just as high." Guan Zheng pointed to the white maggots on the corpse, and Xu Jiuyan was also a little sick to her stomach and coughed dryly.

"Director Shi's home-cooked food, slowly get used to it, it's strange to say, this guy has eaten so many times, and every time he eats it is so fragrant, I won't believe it next time I change the dishes for him." While looking at the corpse, Seki-masa chatted to Yoko, who was vomiting upside down.

The little circle was collecting the eggs of the insects on one side and said, "Leave it to me, I'll give him a stir-fried maggot." ”

Guan Zheng patted Li Chongyang on the shoulder and said, "Look at the small circle of people, how virtuous they are. ”

"The regression equation between liver temperature and time of death: 0~4h is Y=35.37-3.12X and 4~24h is Y=21.59-0.25X......"

"It's all rotten like this, you want to take the temperature of your liver?"

"No, Yoko asked me about the temperature of my liver."

Li Chongyang smiled awkwardly and said, "I'm sorry, I forgot." ”

Xiaoquan ignored Li Chongyang and said, "After the body was exposed to the open air for several hours. There will be eggs on the corpse. Forty-eight hours later. i.e. larvae. Pupae after eight days. After two weeks, it became a flying insect. Pupal shells were found on the corpse. The time of death must be more than three weeks. Within four to six weeks of the summer. Corpse maggots can completely eat the soft fibrous tissue of corpses. ”

"So at least two weeks?"

"Bingo!"

Guan Zheng looked at the messy white bones and asked, "What about the preliminary diagnosis?" ”

Xiao Quan tilted his head, looked at the pile of white bones, and said, "Preliminary diagnosis...... No, how did this die? ”

"You're a forensic doctor, why are you asking me?"

Guan Zheng looked around several times and said, "Yes, how did this die, the bones are all intact, and there is not even a wound." ”

Xiaoquan'er said: "The flesh and skin tissues have been removed, and it is really difficult to say with this pile of bones, so you will know when you go back to the autopsy." ”

"This death is rare enough, you don't see the wound, and you die?"

Xiaoquan'er said: "It's not necessarily that there are no wounds, maybe it's just that we don't see it." ”

Xu Jiuyan asked, "Why wasn't it poisoned or something?" If you poison it, there will be no wounds. ”

Guan Zheng said: "If it is poisoned, generally because the corpse is poisonous, it will not be destroyed by maggots, and the poisoning must be carefully planned, because the choice of poisoning is usually because the murderer is difficult to subdue the victim, or the body does not allow it, so poisoning has also become one of the main means of killing people for the old, weak, sick and disabled, so that the corpse will rarely be thrown into the wild." ”

Xu Jiuyan nodded and said, "Okay, what are you going to do next?" ”

"See what you can see that others can't."

Xu Jiuyan fainted when she heard Guan Zheng say those profound words.

Xu Jiuyan brought two masks, but she still felt stinky and kept pinching her nose, Guan Zheng looked at Xu Jiuyan's difficult expression and said, "Do you want to give you a gas mask?" ”

"I thank you, no need!"
