After driving the corpse back to the funeral home and removing the clothes from the corpse, Xu Yiman started the autopsy. Jiang He asked Guan Deng to contact No. 4 Middle School, but he stayed behind, preparing to conduct an autopsy with Xu Yiman.

For a professional forensic doctor like Xu Yiman, it takes about an hour to two hours for an autopsy to be done on a corpse. During the autopsy, Xu Yiman said very few words, and only occasionally explained a few words to Jiang He.

When the autopsy was completed, Xu Yiman remained silent.

"There are many problems with this corpse!" Xu Yiman took off his gloves, looked at the corpse and said, "In general, I don't know how his injuries were caused."

"What do you mean?" Jiang He asked further.

Xu Yiman said seriously: "There are three points, let's talk about them one by one. First of all, judging from the cause of death of this little boy, there is no doubt that he died of paraquat poisoning. His mouth, respiratory tract, esophagus, and even stomach bags were all covered with paraquat. The traces of withered corrosion, you can see the blood bubbles in this row showing the mobile phase."

Jiang He looked at it, and sure enough, going down the esophagus of the dissected corpse, he could see blood blisters one after another. These blood blisters were large and small, some had ruptured, but some remained round. The shape has not yet been broken, and the blood in it can be vaguely seen.

Xu Yiman pointed to the corpse's lungs again, and said to Jiang He, "Have you ever seen a lung like this?"

Jiang He shook his head, because Jiang He had never seen a person's lungs look like this before. The lungs of normal people are elastic and moist, which is why the lungs can breathe air and expand and shrink. But looking at this person's lungs, it gives people a very dry feeling.

Compared with the lungs of normal people, this lung seems to have become a dry branch, and the surface of the lung looks like the earth that has been cracked for a long time. Even if a person dies, if you inflate the lungs of a normal person, the lungs will still swell, but looking at the person's lungs, it is estimated that it is very difficult.

"It feels so dry and cracked, and it's like the root of a sapling has stretched out countless rhizomes." Jiang He described it.

Xu Yiman snapped his fingers and said, "Yes, your description is very vivid, and we call this phenomenon pulmonary fibrosis, as if a tree has taken root in your lungs, tightly Grab your lungs and make your lungs unable to breathe. So people who drank paraquat did not die of paraquat burning their internal organs. Before that, these people would have respiratory failure of their organs. What you see in his lungs is a symptom of this symptom."

Jiang He nodded seriously, Jiang He really didn't understand these things.

"In other words, it is confirmed that he died of paraquat poisoning," Jiang He said.

"That's right." Xu Yiman pointed to the little boy's arm again: "But this is the problem."

Xu Yiman came to Jiang He from the side of the dissection bed, and this was the side where the boy was missing an arm.

She gently lifted the boy's severed limb and explained to Jiang He, "Look at the flap of the wound, how do you feel?"

"It's very sharp," Jiang He replied.

The boy's arm was severed from the biceps, and the cut cross-section was an oval, forming a slanted downward wound, not a circular cross-section. From the cross-section of the skin flap, it is very neat, which means that the arm should have been chopped off in an instant, rather than being chopped off many times.

The thing that cut off the boy's arm should be very sharp, otherwise it would be impossible to cut the bones so neatly. If this is artificial, the killer's strength should be strong enough to cut off a boy's arm with one knife. Jiang He looked at his biceps, there were people who could do it, but Jiang He knew that he couldn't do it with his strength.

"You said before that the boy wasn't dead when his arm was cut off?" Jiang He asked.

Xu Yiman nodded and put down the little boy's stump: "This is also what I want to discuss with you. Paraquat is very deadly. In terms of the amount this boy drinks, it takes two minutes at most, two minutes for this boy. He will have difficulty breathing and die within five minutes. And the pulmonary fibrosis caused by paraquat is irreversible. According to the amount he drinks, even if he is sent to the hospital, there is almost no way to save the person. After several days of life, he died in agony."

"The mortality rate of people who drank paraquat was 90%, and it was such a large amount. How did the murderer pour the paraquat into it, and did he cut off his arm first and then immediately canned the paraquat. Or? After pouring in paraquat first, he cut off his arm, that's the problem."

"Also." Xu Yiman said seriously: "I didn't detect anything like anesthesia in the blood just now, which means he is awake. However, if someone wants to pour you poison, as a human being Instinct will resist, then the poison will be difficult to pour into his mouth, at least, if he spit it out, some of it will flow out."

"That's right." Jiang He agreed with Xu Yiman's words.

Xu Yiman walked to the other side of the anatomy bed, and she said, "This is the second problem. As long as he resists, he can at least spit out part of the liquid in his mouth. In this way, the corrosive paraquat There will be blisters on the corners of his mouth or on his chin."

"But look." Xu Yiman pointed to the boy's mouth and said, "No, not at all."

"What about the third point?" Jiang He asked again.

Xu Yiman said, "He has a kind of food in his stomach that you can never guess in your life."

"food?"

Jiang He looked at the boy's stomach bag which was cut open by Xu Yiman. Jiang He couldn't distinguish the food inside. It was all black and brown stuffed into a lump, but some vegetable fibers and beans, etc. The things Jianghe can still see clearly.

These foods gave off a sour odor, but as a police officer and a forensic doctor, two people had smelled even more odorous odors, so it was nothing.

Xu Yiman said: "The current instruments have helped us in so many things. In fact, when the test results came out, I couldn't believe my eyes, because we found some human beings in his stomach that would never Used stuff. This stuff is shit, and it's a lot."

"Shit?" Jiang He really couldn't think of that.

Xu Yiman nodded seriously: "You heard it right, it's this thing, who would eat these things?"

"I don't know." Jiang He said, "Is this your third point?"

"No." Xu Yiman shook his head.

"What's the third point?" Jiang He asked.

Xu Yiman said, "Scars, look at the scars on the boy's body as a whole."

With that said, Xu Yiman turned the body over. Jiang He saw that there were contusions on the back of the corpse. Most of these contusions were minor injuries. Some were bleeding seriously, and some had bruises, but in most places, only some skins were bruised.

"Have you seen these small wounds?" Xu Yiman said: "Most of them are caused by the rupture of capillaries, but these injuries are nothing, some are not sensitive to pain, such as you, it must be after these injuries heal. You didn't even realize you had these injuries on your body."

"These small wounds healed quickly, but these wounds on his body were obviously left at the same time. Fortunately, we found the corpse earlier, otherwise, these corpse spots would probably cover these wounds. "

"On the whole, I don't understand very much." Xu Yiman said, "My imagination can't imagine how so many injuries were caused in just ten minutes. It's elusive. And that's three things I'm going to tell you, and three things I'm wondering about."

Jiang He nodded and said, "Let's find out what class and age this kid is in. Actually, the three points you mentioned are not the most important, the most important thing is why this kid has feces in his stomach. , can it be detected as human feces?"

Xu Yiman shook his head: "It's impossible to find out, you can only know that the feces are indeed mammalian, and are likely to be human feces. And these feces were digested in his stomach for about a night. It's time, if it's earlier, I think I should be able to find out whether it's human feces."

Jiang He said, "Let's go, let's check."

Xu Yiman didn't move, she said to Jiang He: "The most important thing is not done yet, the last step of autopsy is to re-install these organs where they should be, and then sew the body up. It's the completion of a real anatomy."

"You are not the only forensic doctor in the autopsy room." Jiang He said, "Let's go."

Xu Yiman said to Jiang He seriously: "Jiang He, I know you will be excited when you have a case, but I am a forensic doctor, I am now using my professional training and personally speaking, the last step must be me. Do, this is my bottom line and respect for the dead. I know you don't understand what I said, but I hope you can understand one day. We are different from other animals because we know how to respect life. "

Although Jiang He didn't understand what Xu Yiman meant, he still said, "Okay, I'll wait for you."

Only then did Xu Yiman smile and stop talking to Jiang He.

Xu Yiman's movements were very gentle, like a warm spring breeze. She moved quickly and gently, reassembled the organs of the deceased, and then stitched up the corpse one by one. She covered the corpse with a white cloth, and as if she had completed all her missions, she followed Jiang He away.

In this world, whether it is good or bad, poor or rich, life is always fair and worthy of awe.
