Li Chengxiang was once again brought back to the serious crime team, and it seemed that the people who entered this interrogation room for the first time had a provocative look in their eyes. They may be thinking in their hearts that since it was an interrogation, they had not found evidence yet. Li Zaixiang is no exception, the CEO of this multinational company has an elegant temperament, and his gestures are full of a kind of extravagance.

No one could have imagined that he would have something to do with such a huge murder case, but it turned out that he was involved. As is customary, Li Duo began to ask him for his name, age, and place of work.

But Li Chengxiang was very uncooperative, he glanced at Mu Haoran and Li Duo lightly: "Don't you all know?" And asked me what I was doing, just write no. If you don't have proof, I'm going to tell you slander. ”

As soon as he saw the arrogant appearance of this group of people, Li Duo was angry, and in the face of such a brute, he didn't have so much pity in his heart.

Directly threw the pen on the table and raised a warning: "Li Chengxiang, let me tell you, you don't have to pretend to be with me here, we won't call you here without evidence, it's best to give me an honest explanation." ”

Li Chengxiang raised his eyebrows and smiled: "If there is evidence, you will judge it if there is evidence." There is a saying, don't you often say that you value evidence rather than confession? Then you just report it and it's over, why are you still asking me? ”

The green tendons on Li Duo's forehead protruded, if the police didn't violate the rules by beating people, he would definitely unload this brute. When he spoke again, he was stopped by Mu Haoran.

Mu Haoran picked up a stack of documents on the table and said, "Okay, Mr. Li, since we are talking about evidence, let's talk about evidence." This morning my colleague sent me an autopsy document. I would like to ask if you can explain to me why Yang Xinxin had been dead for several hours before he fell from the building, and then how he was thrown from your company, the building where you worked. Li Chengxiang was still unhurried: "How do I know, I didn't push her down." ”

Mu Haoran also slowed down his tone, so that he could understand: "I don't know, then I have to give Mr. Li a science popularization, as long as he falls from the building before his death, the moment he lands, the human body will have an instinctive reaction to resist the reaction force on the ground, and the result of this reaction will cause fractures in the large joints of the bones." This is because the joints are the most vulnerable parts of the human skeleton. However, in the case of falling from a building after death, because the human body has no physiological response, gravity will directly hit the corpse, so the fracture location will be irregularly distributed according to the part of the impact, not limited to the joint. ”

"And Yang Xinxin just belongs to the latter, she fell to the ground on her back, and the bones on her body were severely shattered in many places, if she fell from a normal building, the part of her injury should not be like this."

"The second point, if you take 10,000 steps back and say that Yang Xinxin fell from the thirteenth floor by herself, then her body will be about two meters away from the front of the building. However, on the day of the crime, I saw a distance of far more than two meters, and even reached five meters. ”

"The third point, the problem of surveillance video, although we are at the scene of the crime, there is no trace of Yang Xinxin's entry and exit on the floor of your company. However, in the general surveillance video of the entire building, we found that Yang Xinxin entered the building at 11:45 p.m. ”

"When we did the autopsy, based on the digestion of the dissolved matter in the deceased's stomach, we determined that she should have died four hours after eating. Through this time check, assuming that she was eating before entering the company, then the time of her death should be around 3 p.m. on February 14 at the latest, but it was already more than 5 o'clock when my girlfriend and I were shopping on the street that day. What does this mean, it can prove that she had been dead for at least two hours when she fell down the stairs, and that corpse spots had formed on her body, which further confirms the characteristics of her falling from the stairs after her death. ”

After speaking, Mu Haoran closed the information in his hand, Li Chengxiang clapped his hands with handcuffs: "The explanation is wonderful, but I haven't seen her, and I don't know who she is, as for how she fell, I don't know." The company is not my own, and anyone may enter it, so how can I say that I did it? ”

"That's to the point, the last point, why is the Chinese medicine ingredient found in the deceased's body the same as what was found in your office and in your room at home?" Time is precious, in order not to delay everyone's time again and again, Mu Haoran has made all the preparations before the interrogation, as long as it is a question he can think of, he has also thought about it.

Hearing this Li Chengxiang's eyes changed, he probably didn't expect the police to find something related to him, he was running rapidly in his brain, obviously everything had been dealt with, how could he still show his feet, he remembered throwing those things away.

Mu Haoran saw his thoughts and spoke for him: "Are you thinking that everything has been taken care of, why can we still find it in your room." Speaking of which, I really blame you for not being careful, although everything in your office is disposed of, the residue of these drugs is stained and standing in the trash. We're just going to make comparisons with that little bit of residue. And when we searched your home, I don't know if you were in a hurry, we easily found a brown paper bag containing Chinese medicine in the trash can downstairs, and the composition was exactly the same as that in the deceased's body. ”

Verdict on falling from a building: suicide? Accidentally? Homicide?

Falling from a building before death may be a suicide or an accident. Suicide cases are usually accompanied by suicide notes, and in the case of accidents, evidence of the deceased's activities at high places must be found. For example, repairing the antenna on the top floor or moving the potted plant on the balcony will cause the slightest mistake and fall. And if he falls from the building after death, it is obvious that he must have killed him. It is also one of the most brutal and heinous methods of corpse disposal in murder cases.

From the state of the corpse, there are three main ways to determine whether it fell from the building before death or after death.

1. According to the "life reaction" of the wound of the corpse, that is, the state of blood clotting.

After bleeding in a living body, platelets will promote blood clotting and achieve hemostasis due to the self-repair function of life. However, there is no blood clotting in the dead body. The strong impact force of the crash will inevitably cause head rupture, intracranial hemorrhage, visceral rupture, body cavity hemorrhage, and fracture. Generally speaking, there will only be one cause of death for the deceased who falls from the building, which is the position where the human body is in direct contact with the ground when it hits the ground. After the autopsy, the state of internal bleeding can be examined, and it can be judged from the blood clot of the wound in the body whether the deceased fell from the building before or after death.

2. According to the location of the fracture of the corpse.

Whether it is suicide or accident, as long as you fall from the building before death, the moment you hit the ground, the human body will have an instinctive reaction to resist the reaction force of the ground, and the result of this reaction will cause fractures in the large joints of the bones. This is because the joints are the most vulnerable parts of the human skeleton. However, in the case of falling from a building after death, because the human body has no physiological response, gravity will directly hit the corpse, so the fracture location will be irregularly distributed according to the part of the impact, not limited to the joint. Of course, if the deceased also hit an object such as a canopy in the process of falling from the building, causing internal bleeding, it is very likely that there will be more than two causes of death. This must be observed and judged based on the conditions of the site. If there are several causes of death, the wound where the clotted blood clot is the cause of death. Because of the second cause of death later, it is unlikely that the blood from the wound will clot. And it can be easily wiped off without lingering on the wound. For example, the head is broken by the murderer, which has already caused death; However, after being thrown downstairs, the internal organs will rupture, and the internal organs will bleed less and the number of blood clots will be smaller.

However, although the above two methods of determination are accurate, they must be dissected, so they are more time-consuming and laborious.

3. It is based on the location of the corpse.

The higher you fall, the farther away you will be from the building when you land. This is the law of physics and will never change.

For example, if you fall from the fifth floor, the body will fall about one meter in front of the building. Falling from the eighth floor, it was one and a half meters in front of the building. If you fall from the 12th floor, the body will be about two meters away from the front of the building. The strength of the suicide person jumping out of a tall building can be obtained from the experience points of the above statistics. In other words, if you fall from the fifth floor, but the distance is less than one meter, it is likely to be an accident. Because the force of the deceased to leap out of a tall building is less than the force of the suicide. On the contrary, if you also fall from the fifth floor, but the distance is much greater than one meter, it is very likely that you will fall after death. This means that when the deceased falls from the building, the force of a third party intervenes, and the victim has the force to be thrown out, so that when the body falls to the ground, it will be farther than the suicide person will land on the ground.

4. The injuries are mainly internal injuries: because the landing of the body is completed in an instant when falling from the building, and the body surface does not have a violent friction with the ground, the internal organ damage of the corpse is usually much higher than the external injury. These injuries usually manifest as multiple internal organ contusions and open head injuries, such as rupture of the liver, spleen, kidneys, stomach, heart, etc., or cranial rupture. Heavy bleeding due to visceral injuries is also commonly seen at the scene.

For posthumous corpses that are disguised as high-falling, it is necessary to focus on looking for mechanical injuries that directly cause death, such as fatal trauma such as knife wounds. In addition, because the blood circulation of the corpse has stopped, at the moment of impact on the ground, it is often not seen that the heavy bleeding that should be caused by a high fall injury; Nor can blood be found in the body during autopsy. In addition, comprehensive and systematic poisoning testing is required. All of this will expose the tricks of the criminals.
