Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Li Weiguo, director of Xingfu Road Police Station, glanced at the other party and did not ask for Lu Chuan's opinion. After all, as the director of the police station, it was his responsibility to go to the scene of the crime to understand the case. If Lu Chuan had to make the decision on this matter, he would have no need to be the director.

"When did it happen? Do you know the person who jumped from the building?"

The property manager quickly shook his head.

"We don't know this person. There are many companies in Yuanfang Building, and there are about 1000 people living there. So we can't know everyone. It's only been less than 10 minutes since it happened. It's been about seven or eight minutes since we called you."

"Xiao Li, come here and bring a few people to drive out all the people guarding the scene. Tell everyone not to take photos. Those who have already taken photos should delete them and are not allowed to upload them. If any public opinion incidents occur, you will be held responsible."

"Also, set up a cordon around the area."

After explaining these basic situations, Li Weiguo first stepped forward to check the situation around the corpse and determine whether the corpse had a higher mortality rate.

In fact, Wei Guo and his police station are only doing some basic preliminary work. According to the rules and procedures, they need to report to the High-tech Zone Criminal Police Brigade.

To issue a death certificate, the criminal police need to go out, and the police station usually just cooperates.

In the case of accidental death like this, the Criminal Police Brigade needs to issue an accidental death certificate, and then the body can be cremated after the funeral home obtains the death certificate.

As for the autopsy, if it is determined that the death was accidental, an autopsy will generally not be performed.

Of course, there are still a series of things that need to be confirmed, such as the identity of the deceased, the specific location where the person jumped from the building, the on-site investigation, etc. All of these require the Criminal Police Brigade to send professional personnel over, that is, let the criminal police come here to investigate first.

The scene was quite tragic. The other person must have jumped from a high floor. When the body hit the grass, the entire body was basically torn into pieces.

Because the place where the bodies fell was not on a concrete surface or hard ground, but on some short shrubs in the grass, and when the bodies fell, part of them were directly buried in the bushes.

The scene was a bit unbearable to watch.

Li Weiguo just came over to take a rough look at the situation and did not touch the body directly. This was not their responsibility.

"Xiao Zhang, go over with the property management and take two people with you to save the video surveillance and see if you can find out anything about the situation here."

"Also, call the Criminal Police Brigade immediately and ask them to send an on-site investigator and a forensic doctor."

While Li Weiguo was examining the body, Lu Chuan also came over to take a look. The characteristics of a high fall were very obvious.

Of course, the high-position features are obvious, and we cannot directly determine whether the deceased jumped from the building before death or fell from the building after death.

As one of the best on-site investigating criminal police, Lu Chuan can be said to be an absolute expert in this area.

One thing that must be determined in all cases of falling from a building is whether the person jumped before death or was pushed down after death.

One of the more important ways to judge is to observe the wound's daily reaction.

The so-called life reaction here does not refer to the life we ​​usually talk about, but the meaning of life and being alive.

As long as the body is damaged after falling from a building before death, the blood coagulation function exists.

If the person was pushed down after death, the blood would not coagulate because the body is no longer active. That is to say, the blood still has the coagulation function, and the degree of blood coagulation can be used to determine whether the person fell from the building before or after death.

Another is to observe the location of the fracture.

People who have never experienced death from falling from a height have no idea that when a person falls from a height and is close to the ground, they actually have a short period of time to react.

This unexpectedly short reaction time will cause people to subconsciously resist the impact from the ground.

That is to say, during this process, the human body will subconsciously use arms or thighs to block the chest or head.

This can cause fractures in large joints such as the hip or elbow, causing bones to protrude from the body.

If the deceased fell from a building after death, this situation would not occur. Falling from a building after death will cause irregular bone fractures depending on the location of the fulcrum.

However, fractures in large joints, such as the hip, knee, elbow, etc., will not occur.

Another point is that a certain judgment can be made based on the distance between the place where the deceased fell and the building.

Generally speaking, if the deceased committed suicide by jumping off a building, it is very likely that a parabola would be formed in the leaping motion.

In other words, the deceased did not jump straight up or down, but in a parabola.

At this time, the higher the floor the deceased jumped from, the farther the body is from the building.

For example, if a normal person falls from the 5th floor, his body should be about one meter away from the stairs, which will not make much difference.

If the other person was pushed down by someone else, then the distance is greater than one meter. Don't just look at the difference of one meter. Often the difference of a few centimeters can determine whether the other person fell from the building accidentally, committed suicide, or was pushed down by someone.

The distance of an accidental fall should be the smallest, because the other party will not have the force to throw himself outward.

If someone commits suicide by jumping off a building, there will generally be a forward movement, so the distance should be a little further.

If someone is pushed down, the distance will be farther. For example, if someone falls from a 5-story building, the distance at which the other person falls may be about two meters from the hole.

Experienced people will look at the situation first. Just by looking at the distance between the corpse and the stairs, they can basically determine how the person died, or which way of death is more likely.

At present, the distance between the corpse and the building is about three meters, so the other party should have fallen between the 15th floor and the 2nd floor.

Of course, Lu Chuan made this judgment only based on the fact that the other party died from an accident due to free fall or suicide. If he was thrown down by someone, then either the floor was lower or the amount of force used was a problem.

Judging from the reaction of the deceased's wounds, it can be basically confirmed that he fell from the building before he died rather than being pushed down after his death.

Lu Chuan can be sure of this.

In this case, the rest will be up to the Criminal Police Brigade to conduct other specific investigations. (End of this chapter)
