Guo Xianghaili learned that the father of the leper head four died early, and the four sisters and brothers all got married, leaving only the leper head four and the old lady He Shi to rely on each other, and the old woman was delirious, her ears were almost deaf, and it was difficult to discuss the autopsy with her, Meng Tianchu's modern criminal procedure concept is deep-rooted, and the modern criminal procedure law stipulates that the public security organs have doubts about the cause of death and may have the right to conduct an autopsy, without the consent of the deceased's relatives. Therefore, in order to find out the facts of the case, Meng Tianchu decided to conduct an autopsy on the spot.

Haili was hurriedly asking Minzhuang to carry the body to the village Yizhuang with the door panel.

Meng Tianchu instructed Wang Yi and others to conduct an investigation in the village to find out the activities of the deceased before his death, and to see if there were any clues.

In Yizhuang, Murong Yuxue had already prepared the corpse grid and pen and ink, Meng Tianchu first examined the body surface of the corpse, and after untying the deceased's clothes, there were patchy subcutaneous hemorrhage areas on the shoulders on both sides of the deceased, but it was not too obvious. The corpse's mortis has initially formed, with corpse spots mainly located on the head and face, chest, and front of the thighs, but they are not noticeable because the corpse rolls in the pond water, affecting blood deposition.

Subsequently, Meng Tianchu began to perform an autopsy on the corpse.

After Meng Tianchu opened the chest and abdominal cavity, he first dissected the stomach of the deceased. He was surprised to find that most of the food in his stomach was still in its original state, and he could clearly identify meat and vegetables such as lotus white, indicating that the deceased must have been killed at the time of his last meal or just after eating. And there is a strong smell of alcohol in the stomach contents. The deceased's last meal was supposed to be drinking wine and eating meat.

This discovery made Meng Tianchu very encouraging, and from this, it can be preliminarily judged that the person who had the last meal (probably a wine banquet) with the deceased Leper Tousi yesterday is suspected of a major crime!

Meng Tianchu put down the dissection for the time being. Go out to the gate of Yizhuang. Tell a catcher who was waiting outside, and ask him to tell Wang Catcher that they are in charge of investigating, and focus on finding out who had dinner with the deceased last night.

Meng Tianchu called Haili to find a duck and conducted a biological experiment with the stomach contents, and after the duck took the stomach contents cleaning solution, it was just quacking very excitedly (there was liquor in the stomach), but nothing happened. It was confirmed that the stomach contents were not poisonous, and the possibility of death of the deceased after poisoning was preliminarily ruled out.

Continuing the autopsy, no trauma was found on the scalp surface of the deceased's head or skull. Next, there is the place where Meng Tianchu needs to focus on the dissection - the neck of the corpse.

Since no obvious traces of trauma were found on the surface of the corpse, it may be that the body was dumped in the pond after mechanical asphyxiation, although the body surface examination did not find any strangulation marks on the neck, but if the murderer used a soft towel and other materials to cushion it, and then strangled or strangled, there would be no obvious marks on the neck, but. This can only be deceived for a while, cut open the neck, and everything will be revealed. Because as long as it is mechanical suffocation. Indelible marks are left on the neck and internal organs.

It's a pity. Meng Tianchu found no signs of mechanical asphyxia in the neck of the deceased, the cartilage of the respiratory tract, etc., and the previous thoracic and abdominal autopsy did not find hypoxic histological changes in the internal organs such as the heart muscle, lungs, liver, and kidneys. This excludes the possibility of death by mechanical asphyxiation.

Meng Tianchu looked at the dissected corpse in a daze, how did the deceased die?

Seeing Meng Tianchu's expression, Murong Yuxue knew that he had encountered a problem, so he didn't dare to ask, so he sat at the table next to him with a brush and waited quietly.

The chest and abdomen of the corpse were cut open by Meng Tianchu in a Y-shape, the skin and musculature on both sides turned to both sides like two doors, and the upper one turned up to cover the head and face, and the internal organs in the chest and abdomen had been almost removed, leaving only an empty body, like a canoe of the indigenous Indians.

Meng Tianchu's eyes fell on the shoulders of the deceased who did not turn over the ground covered by the layer of skin, and there, there was a piece of dark purple ground bleeding under it, both on the left and right.

How did this come about? Collide? Unlikely, because there are both sides without a collision injury to the head and face, and it is unlikely that it only hit the shoulders on both sides without injury to other parts.

Meng Tianchu pondered, this situation was most likely caused by someone grabbing and pinching his shoulder. Thinking of this conclusion, Meng Tianchu's eyes lit up suddenly, and a thought appeared in his mind.

He bent down to re-examine the neck incision, this time after fully exposing the neck muscles, he focused on the neck ligaments and vertebral plates for a detailed examination, at this time, his eyes were brighter, and he took a bone saw to saw open the vertebral plates, and after carefully examining the cervical spinal cord, a knowing smile appeared on his face.

Murong Yuxue asked happily, "Master Meng, have you found the cause of death?" ”

"Hmm~!" Meng Tianchu nodded, "The deceased's leper head four is likely to be shaken to death!" ”

"Huh? Shake... Shake to death? ”

"Yes, the murderer grabbed the deceased's shoulders and shook violently back and forth, due to inertia, the deceased's head suddenly bent forward and then stretched backwards and repeatedly, resulting in a whiplash-like injury to the neck!"

"Wave... Whiplash injuries? "Murong Yuxue heard this term for the first time. I couldn't figure it out with a big wink.

Meng Tianchu raised his hand into a fist, relaxed his wrist, and then shook it back and forth violently: "The human head is like my fist, and the human neck is like my wrist. This was the case of the deceased's leprosy head four, his fifth and sixth cervical vertebrae were dislocated, the axial odontoid process and the axial vertebral arch were fractured, the ligaments and joint bundles were torn, intra-articular hemorrhage, and the spinal cord was damaged, resulting in his death very quickly. ”

Most of these terms in human anatomy, Murong Zhenxue, have heard Meng Tianchu say it, and they all know it, but the mechanism of injury and death requires the support of rich forensic knowledge, especially the accumulation of practical experience, but it is not something that Murong Zhenxue can fully understand by simply mastering a few terms, so he was confused. However, Meng Tianchu used a human wrist as an analogy, but he vividly explained the occurrence of whip-like injuries, which made Murong Yuxue roughly

How did the damage happen.

In fact. In modern society, whiplash injuries mainly occur in traffic accidents, and most of them are caused by a sudden and violent shaking of the head when the vehicle in which the victim is riding is violently hit by a vehicle that is being rear-ended. and cause damage to the neck and neck. This damage usually results in a soft tissue strain, but in severe cases, it can cause dislocations and fractures of the cervical or vertebrae, damage to the medulla oblongata and spinal cord, and lead to death.

Meng Tianchu continued: "Judging from the damage results, the murderer grabbed the leper head and shook it violently, which proves that the murderer is likely to be burly and powerful. Judging from the fact that the contents of his stomach had a strong smell of liquor, the deceased was probably drunk when he was killed, and he was unable to resist, and his neck was weak to cause such great damage. ”

Murong Zhenxue carefully filled in the information of Meng Tianchu's autopsy on the corpse grid. At the same time, Meng Tianchu stitched up the corpse, performed a simple cleaning, and put the corpse back on clothes.

As soon as I was done, I heard a knock on the door. Murong Yuxue hurriedly got up and opened the door, and Wang Yi, the head catcher, stood at the door, panting a little and said, "Master." Found out. Someone saw Leper Tousi and a neighboring village named Huang Shihu last night. There is also a man named 'Night Crow', who eats and drinks at Night Crow's house. This night the ravens have been controlled by us. The subordinates have already sent a few brothers named Haili to lead the way and rush to the neighboring village to arrest Huang Shihu. ”

"Excellent! Bring the crow of the night. ”

Soon, the trappers brought a stout villager up to his knees.

Meng Tianchu asked, "What kind of 'night crow' are you?" ”

"Yes, Xiaodi's real name is Hai Xiaosan, because he likes to wander around at night without sleeping, and he speaks roughly, so everyone gave the villain this nickname." This night, the crow has a hippie smile on its face, and it seems that he often sees officials, so he is not nervous.

"Were you with the Leper Four last night?"

The night crow hesitated for a moment, and said calmly, "Yes, we are drinking together." "It seems that many people know about their drinking with Leper Four last night, so Night Crow doesn't hide it.

"Tell me what happened."

"Pass?" Night Crow smiled, "There's nothing going on, the three of us have a good time on weekdays, and we drank and bragged at my house last night, and we dispersed when we were done." ”

"Really? Then why did Leper Four die in the pond? ”

The night crow was slightly stunned, and then stiffened his neck and said loudly: "Then how do I know? Ask me what I'm doing! Perhaps he was drunk, passing by the pond and accidentally fell into the pond and drowned. This guy is stupid, who knows! ”

"Reasonably, not loudly!" Meng Tianchu said coldly, "I warn you, you have to answer my questions honestly, if you talk like this again, you will be treated as a roaring court, and you will not blame this master for punishment!" ”

The crow pursed his lips this night, as if he was used to seeing such a scene, but he still lowered his head.

Meng Tianchu asked, "Do you need to pass by the pond when you come out of your house and go back to the four houses of Leprosy?" ”

Meng Tianchu actually didn't know where the four leper families were, and he didn't know the night crow's house, but he had been to the pond twice, and the surrounding environment had been carefully observed, and the pond was located at the edge of the village, and the villagers generally did not pass through that place when they went back and forth in the village, so he asked casually.

The night crow was stunned for a moment, and said, "Who knows why he ran to the pond, didn't he say that the pond was haunted, maybe he was seduced by the ghost and drowned." ”

From the night crow's answer, it is clear that when he comes out of his house and goes back to the four houses of the lepers, he will not pass through the pond. The head catcher Wang Yi leaned into Meng Tianchu's ear and whispered: "Master, we have already asked the old lady of the leper four, the leper went out before it was dark last night, and he never returned home. ”

Meng Tianchu nodded, thinking that the ears of this leper lady were almost deaf, and it would take a lot of effort to ask her words, staring at the night crow and saying in a deep voice: "You guys ate and drank last night, when did it start?" ”

"It didn't take long! After eating for a while, the sun will disperse before it sets! The Night Raven spoke impatiently.

The headhunter on the side said angrily: "Fart! Your neighbor Hai Laofu proved that last night, at about the third watch, you were still drinking at your house, and the sound was very loud, Hai Laofu couldn't sleep, and went to your house to ask you to speak quietly, but you kicked him. Hai Laofu proved that at that time, he saw the four lepers, Huang Shihu, and the three of you drinking in the living room, how did you disperse before the sun set! ”

The night crow snorted and cursed in a low voice: "the old man, this old dog, I will have to clean him up one day!" ”

Meng Tianchu was furious: "What a bold man, he dared to threaten to retaliate against witnesses in front of his master, and when someone came, he dragged him down and slapped his mouth heavily!" ”

The two catchers on both sides stepped forward to grab the night crow and dragged it down, the night crow was strong and struggling, and the two catchers couldn't catch him. Wang Yi snorted coldly, stepped forward, stretched out his fan-like left hand and grabbed the shoulder of the night crow, and smashed his right fist into the stomach of the night crow like a steel pestle.

The night crow snorted, his knees weakened, he fell to his knees with a thud, and then he fell over, curled up in a ball like a shrimp, vomited in his mouth, rolled his eyes, and couldn't even breathe.

Wang Yi didn't pay attention to it, grabbed his hair, pulled him up, picked up his big palm like a fan, and slapped it with a thunderbolt, until the night crow's nose and mouth were bleeding, his cheeks were swollen like a pig's head, and there were few teeth left, so he stopped.

The night crow lay on the ground, not even having the strength to breathe, but only moaning in pain.

Without Meng Tianchu's orders, a catcher had already brought a basin of cold water and poured it on the head of the night crow. The night crow was slightly awake at this time.

Wang Zhutou grabbed him by the hair and dragged him in front of Meng Tianchu, Meng Tianchu squatted down and asked, "How is it?" Do you still want to take revenge on your neighbor Ebichi? ”
