Hearing that there was a problem, Yang Rui and Wang Bing were interested, and the three of them hurriedly ate dinner, cleaned up the table, and sat down at the table.

"You all know what happened to me that night, so I won't go into details. Since it is a homicide, let's talk about the autopsy first. Qiu Yu put the file on the table, and while looking at the bloody photos, he said: "The deceased is a male, the corpse is 178 cm long, short hair, relatively strong, about forty years old, wearing a light blue shirt on the upper body, big yellow shorts on the lower body, and a pair of blue sneakers on the feet, and he is well dressed, but he has not found any items to carry with him." ”

"After an autopsy, it was found that there were some tears on the shirt, which should have been formed during the fight. In addition to dripping and splattering blood, there are also a large number of blood stains and blood infestation. Through the examination of the body surface, it can be seen that the body was covered with dense stick wounds all over the body, and there were some epidermal abrasions, and the stick wounds on the head were the most intensive. After the autopsy, no poisons and drugs were detected in the deceased's body, and alcohol was detected, and the alcohol concentration was not high, indicating that he had drunk alcohol before his death, but he did not drink too much, and was in a very normal state. These epidermal abrasions were supposed to have been formed during the struggle and did not have much effect, while those dense stick injuries all over the body caused multiple fractures in the hands, feet and chest, and the cause of death was blunt force trauma to the head and died of head injury. ”

"Looking at these autopsy photos, we can find that the head of the corpse has indeed been hit with blunt objects multiple times. Most of these wounds are located in the forehead, and there are no less than 30 wounds, resulting in a wide range of open fractures and comminuted fractures of the entire skull. With such a concentration of wounds, it is almost certain that these wounds were formed after the victim was injured and fell to the ground and completely lost the ability to resist. In other words, after the victim lost the ability to resist, the suspect hit the victim on the head at least 30 times with a blunt object such as a club. Therefore, it is also sufficient to characterize intentional homicide rather than intentional injury causing death. ”

"In the victim's posterior occipital area, there were two very severe blunt force injuries of the type of club, and only two of these severe blunt force injuries were on the back side of the head. So, if I'm not mistaken, this is where the victim was attacked in the first place. Just two blows are enough to bring the victim to the ground injured. In addition, the blunt trauma has a distinct directionality, which is obliquely to the upper right. From this, we can also infer that in these two attacks, the suspect used his left hand. And since this is the first attack, then it must be the most important attack, and a normal person will definitely use the hand that he is most accustomed to and the most powerful. Therefore, we can also infer that the suspect should be left-handed. ”

Wang Bing looked dazed, and suddenly asked, "Didn't you have a fight with this suspect that night, are you really left-handed?" ”

"It should be, but this person doesn't seem to be particularly obvious." Qiu Yu said with a frown.

"Why?" Wang Bing asked puzzled.

"I remember that night he was indeed holding a weapon in his left hand, and after I accidentally injured my left hand, it seemed that he had been attacking me with his right hand, and the strength of that right hand was also very strong, and I suffered under his right hand."

"Is this man a strong hand and a weak hand?"

"It's not that much, as long as you are a normal person, there will definitely be a difference between strong and weak hands, but some people have been specially trained, and the difference is not too big, but no matter what, this difference is engraved into the bones since childhood, and it is difficult to change." Qiu Yu thought about it, frowned and said, "Is it difficult, this person has also practiced specially, if this is the case, it is really difficult to deal with." ”

"It doesn't matter if he has practiced or not, as long as the person is confirmed, our special police will clean him up when he is arrested." Wang Bing said with great confidence.

"Hehe......" Yang Rui smiled bitterly and said, "If it's really so easy, we don't have to scratch our heads here." Speaking of this, he suddenly asked, "Taro, are you really okay with this injury?" ”

"Didn't you show me the results of the hospital examination? No fractures or intracranial hemorrhage, nothing serious. Qiu Yu said indifferently: "Speaking of the wound on my head, I have to mention the brick next to the corpse at the scene." The wound on my head, if I hadn't miscalculated, was the brick. The suspect didn't use anything else to knock me unconscious, but he used such a thing to make people think that I was in the process of fighting with the victim, and the victim hit me on the head with a brick, and finally the injury was too serious to support and fainted at the scene. He paused, and then said, "Next, let's talk about the situation at the scene." ”

"The location of the site is on a sidewalk off a main street. Although it is a sidewalk, it is supposed to be built for the sake of urban beautification. Both sides of the sidewalk are lined with flowers and trees, and the scenery may be beautiful during the day, but at night, it becomes extremely hidden. It was raining on the night of the crime, and it was already late at night, so there were basically no pedestrians, so it became an excellent place for tailgating and killing. ”

"The sidewalks at the site are made of stone slabs that have been washed by rain, and there really shouldn't be any visible blood on the ground. But it is precisely because of the rain that when the ground is wet, the dust and mud on the surface become very noticeable. In the photos of the scene, there is a photograph of the ground taken after the body was removed and I was lifted into the ambulance, and if you look closely, you will see that there are several drag marks on my side. This kind of drag marks, if it doesn't rain, are really difficult to find on that kind of floor. In addition, there is some mud and dust attached to the heel of my shoes, which will never be adhered to by normal walking, which is obviously consistent with the drag marks on the ground. ”

"Next, judging by the clothes and pants I was wearing, there were indeed some blood stains on them. There are indeed some of these blood splatters, but in fact, there are more of them that kind of splattered blood. My shoes were a pair of pale yellow nubuck leather touring shoes, but there was almost no blood on them. ”

"What does that mean?" Wang Bing asked with a blank expression.

"Meaning, these are two different forms of blood." Qiu Yu explained: "Splattered blood stains are formed by the pressure of blood flow from the human body, while blood splatters are formed by blood splattering in all directions, and the two types of blood stains are sometimes difficult to distinguish, but there are obvious differences. ”

"I still don't get it." Wang Bing said with some embarrassment.

"Quite simply, since there is blood splattered on my body, it means that the deceased was killed after I passed out. In other words, the deceased did not die from the injuries I sustained before I fainted, but because I was severely injured by someone else after I fainted. When this man was badly wounded, I was right next to the deceased. Qiu Yu patiently explained: "And those blood splashes mean that the injured and bleeding parts of the deceased's body were repeatedly hit, and only then did a large amount of the blood that had flowed out of the body splash on my clothes and pants." Got it now, right? ”

After hearing this, Wang Bing thought for a while before he seemed to understand, and asked again: "Then what does the lack of blood on your shoes mean?" ”

"It shows that this is a fake scene, and it shows that he was framed." Yang Rui said suddenly.

"Yes, that's what it is." Qiu Yu nodded, and saw that Wang Bing was still at a loss, so he had to explain again: "Just imagine, the suspect is standing next to the victim, and the victim has fallen to the ground and can't move, but he is still holding a baton and hitting the victim's head constantly. At this time, the blood kept spurting out, coupled with a large amount of blood splashed during the blow, the suspect should have blood splashed everywhere all over his body, how could it just appear on his clothes and pants, but not on his shoes at all. ”

After listening to this explanation, Wang Bing suddenly realized, nodded vigorously, his eyes were full of admiration, and he said very seriously: "This shows that the head of the deceased in your shoes at that time was relatively far away, and blood stains could not be splashed on your shoes." I really admire and admire that I can say so many things by looking at the photos. ”

Qiu Yu's old face flushed, and he was a little embarrassed.

"Can you deduce what happened that night?" Wang Bing suddenly said naughtily.

"What, are you going to test me?" Qiu Yu said with a wry smile.

"Even if it's it!" Wang Bing is still very naughty.

"Actually, even if you don't ask, I'm going to say it. Because, it's critical. Qiu Yu thought for a moment, then continued: "Judging from the photos, the sidewalk where the crime occurred happened to lead to a nearby village, combined with the victim's clothing characteristics, walking route and weather conditions that night, it should be more likely to go back to that village." That night, the deceased was supposed to have gone out for a drink, either in a taxi or by a car to the vicinity, intending to walk into the village. The suspects were either crouching around or had already followed them. When he arrived at the scene, the suspect felt that this was the best way to get off the scene, so he quickly stepped forward and slammed the unconscious victim on the head from behind with a baton that had been prepared. The victim of the blow instantly felt the world spinning and fell to the ground, but at that time, he had not completely lost the ability to resist. The suspect then began to pick up the baton and slammed it at random on various parts of the victim's body, and the victim could only resist desperately. At this time, I accidentally showed up. After I stopped him, the man didn't know what he was thinking, but he ran away and returned to the scene, knocking me unconscious. ”

"There was no longer any obstacle from others, and the suspect completely let go of his hands and feet, found the baton that I had knocked down before, and began to carry out inhumane revenge on the victim." Qiu Yu thought about it, and said with great certainty: "That's right, it's revenge." Armed with a baton, he continued to slam the victim until the suspect was dying. At this time, he has not forgotten one point, that is, the disaster leads to the east wall. He put the hood on my head and dragged it closer to the victim's head before he began to punch him dozens of times on the head until he was sure that there was no chance of the victim being alive. During this process, a large amount of blood gushed and splashed on my body, and because my feet were far away, there was no blood left on my shoes. After that, he dragged me to a relatively reasonable position, and then shoved the baton into my hand and threw the brick next to the body. Before leaving, he also took all the belongings of me and the victim from us. ”

Qiu Yu frowned, and then said: "To be honest, until now, I haven't figured out why he suddenly ran away when I was fighting with this suspect, he obviously had the upper hand. Knocking me unconscious and then blaming me is not only straightforward, but also reduces the risk. ”
