"What is the best way to destroy evidence in a homicide case?"

In the office of the serious crime team, the boss Shen Ruoshan asked us a question with a smile.

"Let the corpses disappear forever." Lin Zifan replied with a smile.

"How do you make the corpse disappear?" The Boss asked again.

"Burn to ashes! There's nothing that can't be solved by fire. Li Meng raised his hand to answer, like an elementary school student answering a question in class.

The boss rarely talks to us, or we rarely see him. It's not that he's mysterious, it's that he's too busy.

It's not that he's very busy at work, after all, he has entrusted all the work to us, and he's an old detective who is about to retire, so he doesn't need to be too busy.

The reason why he is busy is because he is busy with his family.

He goes to work on time and never a second early, and in the same way, he leaves work on time and never delays a second. He took off his police uniform, a son, a husband, and a father. He, like thousands of men in the world, has family on his shoulders.

Like us, he likes to fish when he goes to work, hides in the office and watches dramas, usually gossips, and occasionally makes some jokes and jokes about some interesting things.

Having said all that, I just felt that he wouldn't suddenly ask us this strange question.

Obviously, no one but me found this question weird.

After hearing Li Meng's answer to ashes, the boss was a little dissatisfied, and denied with a smile: "This kind of thing can only be operated by the crematorium, and it is difficult to do it yourself." ”

"Then eat it!" Jiang Tingbai quipped casually.

Sure enough, his favorite thing is food.

"Huh—it's disgusting to eat human flesh." Li Meng pursed his lips, his face full of disgust.

"What's so disgusting about this, there have been many cannibalism in history! Haven't you heard of the cannibal tribe? Specialized in cannibalism! Jiang Tingbai stared hard into his little eyes and explained to Li Meng seriously.

Hearing this, Li Meng's facial features were all screwed together, and he was very resistant in his heart.

When Jiang heard Bai seeing her expression, he suddenly became interested, and he had to tell Li Meng about cannibalism.

"Do you know why doctors like to eat barbecue? Because when they are doing surgery, they cut human flesh with an electric knife, and the fragrance it emits may have a Maillard reaction, and then people will especially want to eat barbecue. Jiang Tingbai talked nonsense seriously, and Li Meng was stunned.

As for the fact that doctors like to eat barbecue, forensic doctor Ren Qiushi is an expert, and he often invites me to have supper, and all I eat is barbecue. However, he was not because of any Maillard reaction, but because he left work late and only opened a barbecue stand.

"Really?" Li Meng actually believed Jiang Tingbai's nonsense, and asked seriously.

Jiang Tingbai originally wanted to pretend for a while, but he couldn't help it, and suddenly laughed: "Of course it's fake!" Hahahaha! ”

"Old dog!" Li Meng found out that he had been tricked, and when he stood up, he wanted to go over and kick him a few times.

Seeing that our answers were gradually deviating from the boss's question, Xue Hang, who had not spoken, suddenly said, "Broken corpses." ”

The boss's eyes lit up, he was very satisfied with Xue Hang's answer, and asked, "What about after the corpse is broken?" ”

"Throw the corpse." Xue Hang replied in a deep voice.

He talked about the shredding and throwing of corpses in a voice without any emotion, and in a trance we had the illusion that the unsmiling person in front of us was a murderer.

Jiang Tingbai was still immersed in the joy of deceiving Li Meng, and said casually without care: "What a waste of throwing corpses, anyway, they are all cut into small pieces, cooked and eaten!" Hahaha! ”

He laughed for a while, and then stopped laughing, for he saw the boss's serious face.

"A steamed bun shop in Beihuai Town was reported to be filled with human flesh." The boss didn't have a smile on his face, and said solemnly.

……

Beihuai Town is an ordinary rural town, and correspondingly, there is also a Nanhuai Town.

The dividing line between the two towns is a large locust tree, and when the two towns were divided, there was a lot of trouble over this locust tree, and it was later decided to use the locust tree as the boundary.

All members of the serious crime team set off and drove to Beihuai Town.

On the way, Jiang Tingbai once again told the story of the cannibals, but this time Li Meng came prepared: "The cannibals have disappeared in the fifties of the last century, and now there are no cannibals!" ”

"Although the cannibals are gone, we are all descendants of the cannibals." Jiang Tingbai suddenly burst out with a sentence, and once again stunned Li Meng.

"Why are we the descendants of cannibals?" Li Meng asked puzzled.

On the side, Xue Hang suddenly spoke: "Because of prions." ”

He then explained: "There is a prion in the human nervous system, which is extremely difficult to kill, and will remain in the human brain for a long time after the person eats and cannot be digested, causing the misfolding of proteins in the human brain, and then killing the cerebellum very strongly."

The human cerebellum is related to coordination, if the cerebellum is strongly killed and finally bored like a sponge-like hollow structure, the person will tremble, then lose the ability to speak, lose the ability to swallow, and finally die of incontinence.

BSE is caused by this prion because people feed cattle with the discarded parts of the cow, including offal, from the slaughterhouse. Cattle eat their own kind, causing prions to kill the cerebellum.

Some people are naturally resistant to prions because they have PRNPs (prion genes) on chromosome 20 that resist prion attacks.

Cannibalism has been practiced since the Paleolithic, and after a long period of time and species selection, only those who are resistant to prions survive, and the rest will die.

Chromosomes can be inherited, so, we were all descendants of cannibals at one time. ”

Xue Hang is worthy of a walking encyclopedia, he knows everything, and he can explain it clearly to you.

Jiang Tingbai was very unhappy, explaining that prions should have been his business, but he didn't expect Xue Hang to be in the limelight.

"So, no one eats human flesh at all." Lin Zifan suddenly interjected.

"This is also a strange point, how can the source of human meat be stable from pigs, cattle and sheep, and the cost of making human meat buns is very high. It's not the cross slope of Sun Erniang in the Water Margin, there is a steady stream of human flesh. Xue Hang said in a deep voice.

"Judging from the current situation, it should be that the owner of the bun shop killed someone, and in order to destroy the corpse and destroy the traces, he made steamed buns out of human flesh. After killing someone, he can still be so shocked to dissect the corpse and rubble, and finally make a bun very calmly, and the murderer's psychological quality is extremely high. Li Meng opened his mouth and analyzed the situation.

"There is also a possibility that the owner of the bun shop didn't know that it was human flesh......"
