Under normal circumstances, firefighters are the ones who deal with fire scenes, and the police generally do not go there.
The police will only arrive at the scene unless the fire scene is chaotic or the fire area is relatively large, or someone calls 110 and the nearby police station.
But this time the scene was different.
After the fire broke out yesterday, it took the firefighters about half a day to put out the fire. at the fire while the cause of the fire was investigated. Some signs of arson were found at the scene.
Not only that, when cleaning the fire scene, they also found two bodies.
At the scene, fire personnel were continuing to communicate with Lu Chuan.
“The two bodies were not burned to death.”
Firefighters who often deal with fire scenes know very well what kind of state the burned bodies are in.
“We noticed something was wrong here, so we called you.”
Now, the bodies are still placed at the scene.
The handling of a fire scene does not mean that the fire department will put out the fire and be done with it.
Under normal circumstances, after firefighters deal with the open flames at the fire scene, they will also conduct a detailed investigation of the fire extinguishing scene.
One of the most important reasons is to find the cause of the fire and analyze the cause of the fire.
The fire department must provide a fire analysis report.
It is highly professional.
The fire was in a warehouse.
It’s just that this kind of warehouse is surrounded by many self-built houses in residential areas. When such a warehouse catches fire, the area burned will be relatively large, and it will also have a lot of impact on the surrounding areas.
The scene was very chaotic, because after the fire extinguishing, there was a black substance of water mixed with burning materials everywhere.
Lu Chuan had inspected similar scenes before and encountered similar cases, and it was quite difficult to deal with them.
Because fire scene investigation is usually difficult.
Comparatively speaking, a completely burned fire scene is easier to survey than a fire scene that has been extinguished by fire water.
“This corner is the initial location of the fire.”
The firefighters have found the initial location of the fire in the warehouse.
In the northwest corner of the warehouse, near the door.
Lu Chuan took a look, squatted down on the ground, picked up the burned ashes, put it under his nose and smelled it.
There is a faint smell of gasoline.
"Did the murderer pour gasoline here and then light it?"
The firefighter nodded. He didn't expect that the criminal police captain opposite him actually had some research on fires.
"It should be deliberately arson."
In fact, most people have rarely seen what a real fire scene looks like.
Generally speaking, the smell at the scene after a fire is very complex and pungent.
The smell of many things will be amplified after burning, and many smells are easy to distinguish at the fire scene.
Although the effective substances are volatilized after the gasoline is ignited, the residual gasoline smell can actually be detected for a long time.
Although the scene had been almost destroyed by fire fighters, and firefighters later came in to inspect the fire scene, Lu Chuan felt that it still had great investigation value.
"In this way, we will leave the scene to us. If you need technical help on the fire situation, we may also ask our fire department to help."
The other party nodded: "No problem, please contact us anytime if you need anything." The handover of the scene has been completed, the fire department has withdrawn directly, and the rest of the scene has been handed over to the criminal police.
Lu Chuan quickly arranged and investigated the relevant work, and the three squadrons began to divide the work.
"Wang Zhaokai, our No. 1 Squadron is responsible for visiting and investigating the surrounding situation. Who called the police yesterday and whether there were any abnormal findings. The visit and investigation will make it clear."
"Chen Jiang, you The Second Squadron is responsible for investigating all nearby surveillance videos, whether public or private, and finding all the surveillance videos from the incident last night."
When Lu Chuan first entered the alley, he saw a lot of surveillance cameras on the roadside, and some stores also had their own surveillance cameras installed yesterday. If someone sets a fire at night, the person is likely to be photographed.
"Sun Biao, check the situation in this warehouse."
After a few people received the order, Lu Chuan led the criminal police brigade to conduct an on-site investigation, and the criminal police entered the scene directly.
“Start from the door, and push inward little by little, don’t be anxious.”
Fire scene investigation is different from ordinary on-site inspections, which can only be done at a glance See clearly what the entire scene looks like.
But the fire scene was mostly covered in ash and other coverings.
You need to start from one point and clean up and advance bit by bit.
No detail can be missed.
According to the investigation results of the fire department, the murderer should have set fire to the scene after killing the people to cover up the traces of the murder.
Setting the scene on fire means that the murderer should have left many traces at the scene that are not easy to clean. Another is to conceal the identity of the deceased.
The body has been carried out by the forensic doctor.
The specific cause of death cannot be determined until an autopsy is done, because the surface of the body has been burnt.
Now I can’t tell how he died.
As for the traffic police, they determined that the body was not burned to death, mainly because the body was not curled up.
Normally, after a person is burned to death, his body will curl up.
However, of the two bodies found at the fire scene, one was on his back and the other was on his face. Except for the burnt front, the part next to the ground was intact.
Both bodies are stretched out, there must be something wrong with that.
Actually, fire is not the best way to simply destroy a murder scene.
Many criminal suspects feel that if everything at the scene is burned by fire, there will be no trace of themselves. I can't find anything, but that's not what it looks like.
This is especially true for a scene that was not completely burned down.
At the point of the fire, Lu Chuan found a burned lighter in the corner.
Although the lighter has melted, it is only partially melted and the upper part is relatively intact.
If the murderer used this lighter to light it and then threw the lighter away, then Lu Chuan had it. The other party's fingerprints may be extracted from this lighter.
In addition, because there are a lot of combustibles in the warehouse, but they have not been completely burned, there are many items scattered on the ground that have not been completely burned, but have a protective effect on the ground.
Lu Chuan and the others only excavated a few places and found some blood stains underneath.
Subsequent investigation and excavation revealed a dagger on the ground near the body.
Half of the handle of the dagger has been burned off, but there is still some residue on the half next to the ground.
There are brown traces on it, which should be blood stains.
This is most likely the murder weapon. (End of this chapter)
