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

Normally it is the firefighters who handle the fire scene, and the police usually do not go.

Unless the fire scene is chaotic or the burned area is large, or someone calls 110, the police from the nearby police station will arrive.

But the scene this time was different.

After the fire broke out yesterday, it took the firefighters about half a day to put out the fire. When investigating the cause of the fire, some traces of arson were found at the scene.

Not only that, they also found two bodies while cleaning up the fire scene.

At the scene, firefighters were continuing to communicate with Lu Chuan.

"These two bodies were not burned to death."

Firefighters who often deal with fire scenes know very well what the state of a burned body is like.

"We found something wrong here, so we called you."

Now, the bodies are still lying at the scene.

Dealing with a fire scene does not mean that the fire department is done once they put out the fire.

Generally speaking, after dealing with the open flames at the fire scene, firefighters will also conduct a detailed investigation of the fire-fighting 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 needs to provide a fire analysis report.

It is highly professional.

The fire was in a warehouse.

However, this type of warehouse is located in a residential area and there are many self-built houses around it. When this type of warehouse catches fire, the burned area is relatively large and has a lot of impact on the surrounding areas.

The scene was very chaotic because after the fire was put out by firefighters, black substance mixed with water and burning materials was everywhere.

Lu Chuan had inspected similar scenes and encountered similar cases before, and they were still quite difficult to handle.

Because fire scene investigation is usually difficult.

In comparison, a fire scene that has been completely burned out is easier to survey than a fire scene that has been put out with fire water.

"This is where the fire started."

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, picked up the burning ashes on the ground, put them under his nose and smelled them.

There is a faint smell of gasoline.

"Did the murderer pour gasoline here and then set it on fire?"

The firefighter nodded. He didn't expect that the criminal police captain opposite him actually had some knowledge about fire.

"It must have been arson."

In fact, most people have rarely seen what a real fire scene looks like.

Generally speaking, the smell at the scene of a fire is very complex and pungent.

The smell of many things will be amplified after burning, and many smells can be easily distinguished at the scene of a fire.

Although the effective substances in gasoline are volatilized after being ignited, the residual gasoline smell can actually be detected for a long time.

Although the scene had been almost destroyed by the firefighters, and later some firefighters came in to inspect the fire scene, Lu Chuan still felt that it was worth investigating.

"In this case, the on-site situation will be handed over to us. If there is any technical assistance regarding the fire situation, we may need to ask for help from the fire department."

The other party nodded: "No problem, feel free to contact us if you need anything." The scene had been handed over, and the fire department retreated directly, leaving the entire scene 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 first squadron is responsible for visiting and investigating the surrounding situation. Who called the police yesterday? Did you find anything unusual? Visit and investigate clearly."

"Chen Jiang, your Second Squadron is responsible for investigating all nearby surveillance videos, whether they are public or private. Find all the surveillance videos from the time of the crime last night."

When Lu Chuan just entered the alley, he saw a lot of surveillance cameras on the roadside, and some shops also had their own surveillance cameras. If someone set a fire yesterday night, they would most likely be photographed.

"Sun Biao, check the situation in this warehouse."

After several people received the order, Lu Chuan led the criminal police brigade to conduct an on-site investigation, and the criminal police went directly into the scene.

"Start from the door and move forward little by little. Don't be in a hurry."

The investigation of a fire scene is different from a general on-site investigation. For a general scene, you can see what the entire scene looks like at a glance.

But the fire scene was mostly covered with ashes and other coverings.

You need to start from a point and clean up little by little.

No detail can be overlooked.

According to the fire department's investigation results, the murderer should have set fire to the scene after killing someone in order to cover up the traces of the murder.

Setting fire to the scene means that the murderer must have left many traces that are not easy to clean up. Another reason is to conceal the identity of the deceased.

The body has been carried out by the forensic doctor.

The specific cause of death can only be determined by an autopsy because the surface of the body has been burned.

Now it is unclear how he died.

As for the traffic police's conclusion that the body was not burned to death, the main reason was that the body was not in a curled up position.

Normally, when a person is burned to death, his body will curl up.

However, of the two bodies found at the fire scene, one was lying on its back and the other was floating. Except for the burnt front part, the part touching the ground was intact.

Both bodies were stretched out, which must be a problem.

In fact, fire is not the best way to destroy a murder scene.

Many suspects think that a fire can burn everything at the scene, and that there will be no trace of them and nothing can be found. But this is not the case.

This is especially true for a scene that has not been completely burned down.

At the fire site, Lu Chuan found a slightly melted lighter in the corner.

Although the lighter has melted, only a portion of it has melted, and the upper part is still relatively intact.

If the murderer lit the cigarette with this lighter and then threw it away, then Lu Chuan might be able to extract the other party's fingerprints from this lighter.

In addition, because there are many combustible materials in the warehouse, but they are not completely burned, many items are scattered on the ground and are not completely burned, which actually protects the ground.

Lu Chuan and his team only excavated a few places and found some bloodstains underneath.

Further investigation and excavation revealed a dagger on the ground near the body.

Half of the handle of the dagger had been burned off, but there was still some residue on the half that was touching the ground.

There are brown marks on it, which should be blood.

This is most likely the murder weapon. (End of this chapter)
