Yang Rui sorted out his thoughts for a while, and then said slowly: "Our largest shantytown here, called Hudong Community, was being demolished and renovated at that time. The first case two years ago occurred in a building that was about to be demolished. The caller was a demolition worker, who was found during a routine inspection before the house was demolished. The deceased was a man who had been tied to a coffee table with a rope and was lying on his back, stripped of his clothes. Clothes, pants, and shoes were randomly scattered on the floor next to the coffee table, and DNA tests determined that it was the deceased. No items were found in the clothes, let alone any communication tools such as mobile phones, so the technical detectives did not play any role in this case. ”

"The building was in the middle of the complex, and the scene was in the living room on the first floor, and the room was empty. Aside from the coffee table, a couple of broken stools and a few messy clutter, almost nothing. The coffee table looked very shabby, and it was later confirmed that the original owner did not want to move and left it. ”

"The deceased was of medium build, 170 centimeters long, looked to be about thirty-five years old, with medium-long hair, a square face, and no beard on his face. The deceased had a rag tightly stuffed in his mouth, and his body was covered with sharp wounds, and the forensic autopsy carefully counted one hundred and three. These one hundred and three sharp wounds, all of which were formed by cutting, large and small, densely crawled all over the person's body, almost every part, and even shengzhiqi was cut off. The blood had dried up and was all over the body of the deceased and all around it, and I will never forget that bloody scene in my life. ”

"The time of death of the deceased was between 24 and 48 hours, and combined with the scene and the circumstances of the investigation, it should have been late at night before the crime. There was no food in the stomach of the deceased, and no drugs, poisons or narcotics were detected in the body, but a large amount of alcohol was detected, indicating that he had drunk a lot of alcohol before his death. Although there were one hundred and three sharp wounds on his body, none of them were fatal, and the cause of death was hemorrhagic shock. Almost all of the sharp wounds avoided the main blood vessels of the human body, the deepest was not more than three centimeters, the edges of the wounds were extremely smooth, and the obtuse flaps were simply invisible. Therefore, we believe that the perpetrator has certain medical knowledge, and the tool of the crime should be a razor blade, and the scalpel blade used by the doctor should be the most consistent. ”

"There was almost nothing of value left at the entire scene, no tools for committing the crime, no fingerprints, no footprints, all the blood stains and samples extracted, after examination, either belonged to the deceased or to the original owner of the house at the scene. At that time, the rope that bound the deceased was a top priority, but unfortunately there was still no valuable DNA found on it. The only thing of value was a photograph attached to the chest of the deceased, with only a red grimace on it. Yang Rui said, turned on the phone, pulled out a photo, handed it to Qiu Yu, and said: "This is my remake, which is almost exactly the same as the pattern of the hood on your head." ”

Qiu Yu took the phone, stared at the picture on the screen carefully, and after a while, opened the file again, and compared it with the photo of the hood in the file repeatedly.

"That's right, except for a few minor differences in the details, it's almost exactly the same." Qiu Yu frowned and said, "I seem to have seen this pattern somewhere, but I can't remember it for a while." ”

Yang Rui smiled bitterly and said disappreciatively: "Before this, many people have said this, and we also checked this thing at the beginning, but I thought that there was no progress, so I gradually gave up." Combined with the on-site investigation and autopsy, we believe that this was a premeditated intentional homicide. The suspect chose the location of the murder here, which is indeed concealed and safe, and he should have stepped on it before the crime. There is no doubt that the deceased should have been brought here by the suspect while drunk, and this scene, to be exact, can only be regarded as the second scene, and the place where the suspect took the deceased is the first scene. We have retrieved a lot of surveillance video and spent a lot of manpower and material resources, but you also know that this kind of work without any direction is tantamount to looking for a needle in a haystack and has no effect. ”

"Judging from the comprehensive scene investigation and all the investigations, this case is enough for one person to complete, so the suspect should be just one person. This person has a strong anti-investigation ability and has a certain amount of medical knowledge, so we initially delineated the scope of investigation to people who have been engaged in or are engaged in the medical industry. After extensive investigation, no suspicious persons were found. Because the suspect's methods are extremely cruel, we attach great importance to this case, and the case is sponsored by the criminal investigation detachment of the Jingjiang City Public Security Bureau. Yang Rui sighed and said helplessly: "As the main person in charge of this case, I have led someone to investigate for nearly half a year, but I have found nothing. ”

"When encountering such a criminal suspect, no matter who is responsible, it should be as big as a fight." Qiu Yu smiled bitterly and said, "Let's talk about the other one!" ”

"In addition, in this case, the place of the crime is not in the city, but in the mountains. At that time, the body was found by an old man herding cattle. Yang Rui said with a bitter face: "We really didn't expect that this Red Devil Butcher could actually go to the mountains to commit crimes. ”

"Four months ago, we received a notice from the Jingcheng District Public Security Bureau that a body had been found tied to a tree in a valley in Xihe Township. Xihe Town is the most remote mountainous township in Jingcheng District, although it is relatively far away, but because of its abundant products and concentrated population, it can be regarded as a relatively fast-growing mountainous township. ”

"The valley where the site is located is very remote, and the nearest village is two kilometres away. We drove to the side of the road closest to the valley and walked for about 20 minutes to the scene. The site is at the very bottom of the valley, which is full of bushes and some unknown trees, and a small stream flows outward along the valley, and the side of the stream is covered with reeds taller than a person, and at first glance it is a good summer retreat. It's a pity that all the beauty is completely ruined by an extremely disgusting corpse. ”

"The corpse was standing under a tree, the trunk of which was the thickness of a man's thigh, and his hands and feet were fixed to the trunk with ropes, and a rope was tied around his neck, which hung from the trunk above his head. The corpse's clothes were also stripped naked, and they stood there naked. The clothes, pants and shoes on the body were thrown aside, and no belongings were found. The deceased was covered in blood, as if he had been drenched in blood. The blood had long since dried up, and it was black and sticking to his skin, like he was wearing a black tight-fitting coat. ”

"Are you sure you want to tie it to a tree before you kill it, or do you want to tie it up after you kill it?" Qiu Yu asked suddenly.

"There is no doubt that the people who were tied to the tree first and then killed."

"Did you use a police dog?" Qiu Yu asked again: "In that kind of inaccessible place, as long as it doesn't rain, the effect of police dog tracking should be good." ”

Yang Rui looked helpless and said: "We thought the same way at the time, it just happened that it hadn't rained in the past few days, so we used tracking dogs. The dog worked really well, took us to the place where we parked, and there was no follow-up. ”

"This is enough to show that the suspect, like you, also drove there." Qiu Yu could only shake his head helplessly, and said, "Moreover, the victim should have been in his car at the time." In that kind of remote place, the victim certainly didn't ask for it. Therefore, the victim should have been in a state of complete inability to resist at that time, either unconscious or tied up, and he was carried to that place by the suspect. ”

Hearing this, Yang Rui glanced at him, there was something strange in his eyes, and said, "It seems that you guy is really not in vain." You're right, the deceased should have been in a coma at the time. Because, we found extremely high concentrations of ether in the mouth and nose of the corpse. ”

Hearing this, the look of adoration on Wang Bing's face became stronger and stronger.

"Through the on-site investigation, apart from the blood stains of the deceased, as well as the ether extracted from the mouth and nose, and a photo of the deceased's chest pasted with blood, we did not find any valuable trace evidence, fingerprints, DNA, footprints, nothing."

"Is it still that red grimace in the photo?" Qiu Yu asked with a frown.

"Well, it's exactly the same."

"What kind of rope are those ropes made of? And how do you tie the knot? ”

"The rope is the most common kind of cotton rope on the market, the material and thickness are very similar to the previous case, and the knot is a simple dead knot, and there is not much difference from the previous case."

Qiu Yu frowned, could only nod helplessly, and asked, "What is the autopsy?" ”

"The deceased was thin, about 165 to 170 centimeters tall, about 40 years old, with short hair and a Chinese face. The medical examiner removed a large amount of sample from the surface of the corpse before placing the body. After the cleansing, we found that the suspect's modus operandi was strikingly similar to the previous case. The various parts of the deceased's body, no more, no less, were exactly one hundred and three sharp wounds, and the main blood vessels of the human body were also avoided, the deepest was not more than three centimeters, the edges of the wounds were equally smooth, and the obtuse flaps were still slightly invisible. The deceased's mouth was also gagged, but this time it was not a cloth, but a stone. In the mouth of the deceased, the medical examiner took great difficulty to remove a pebble almost the size of a fist, which was everywhere along the creek at the scene. Also, his lower body is still there, and it has not been cut off like the previous one. These are the only two things that are different. ”

"The tools of the crime should still be the same blades. No drugs or alcohol were detected in the deceased's body, except for the narcotic ether. The time of death should also be between 24 hours and 48 hours. Yang Rui paused, frowned again and said, "Speaking of which, there is something we haven't figured out until now. ”
