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

Lu Chuan spent a lot of time on these two key parts of the outdoor investigation, but he also obtained many clues accordingly.

"Was the door locked at the time?"

Before entering the room, Lu Chuan carefully observed the condition of the door and found no signs of violent damage.

Zhao Zhigao shook his head. The door was the key area they had inspected at that time.

"The door was not locked. We contacted the family that day. They left the village a month ago. All the valuables in the house have been moved out. The remaining items are waiting to be demolished."

Zhao Zhigao then pointed to other houses around that had hardly been demolished.

"The same is true for several other households around here. If they lock their houses, they have to pay for padlocks, so they don't lock their houses and just wait for demolition."

Because the decoration of this house is not particularly good.

There are some houses in the village that were built in recent years. The owners will remove the plastic steel windows and better doors and sell them.

Houses like this are not worth demolishing, so they are just left here.

"The door handle was wiped and no fingerprints were picked up."

This is relatively easy to understand. If the murderer had not touched the door handle or handled it, there should be fingerprints on it, although they may not necessarily be the murderer's.

But there are no fingerprints on it, so it must have been wiped.

Open the door and enter the room, where you will see the stove.

Although five or six days had passed since the crime occurred, Lu Chuan could still seem to smell the faint aroma of meat.

There was still blood in the big iron pot that had not been cleaned up at all.

"Has the amount of blood in the pot been tested at that time?"

Zhao Zhigao nodded: "The other party must have mixed water into the blood, otherwise it would have been burned dry long ago. When we came back, the blood looked a bit like blood tofu."

"However, based on the iron content in it, we did some experiments and were able to basically determine that it was the amount of blood of an adult. Of course, this also confirmed that it was indeed human blood."

"It's just that... because the blood has been cooked, many biological characteristics have long disappeared, and there is no way to determine the blood type. In fact, from the perspective of our on-site investigation, we cannot determine that the blood in the pot belongs to the deceased Wang Jingya."

Zhao Zhigao said this to tell Lu Chuan that from the perspective of the on-site investigation, there was no concrete evidence to support that the blood in the iron pot was Wang Jingya's blood.

Of course, from a logical point of view, it is another situation.

It was not that only one victim was found at the crime scene. Although the body and the blood were separated, from a logical point of view, the blood should belong to Wang Jingya.

"Director Zhao, let me use the ultraviolet lamp."

It was impossible for Lu Chuan to bring all the inspection equipment here, so he used the on-site survey equipment from Zhao Zhigao.

Lu Chuan first used an ultraviolet lamp to shine around the entire stove, but found no traces of blood.

"Sure enough, there are no blood spots."

If the murderer had let Wang Jingya bleed on the stove, and then let the blood flow directly into the iron pot.

Then no matter how carefully the other party handles it, theoretically some blood will spray out of the iron pot.

Even if the other party wiped it carefully, it is impossible to completely remove the blood.

Even if it cannot be seen on the surface, because the bloodstain contains a lot of iron, the ions can be detected no matter how much time has passed unless these chemicals are treated.

Zhao Zhigao really admires Lu Chuan.

"Captain Lu, we have scanned the entire room and found no bloodstains anywhere."

If Lu Chuan hadn't said that this was not the first crime scene, no one would have thought of this. But now it seems that from the perspective of on-site investigation, this is indeed not the first crime scene. The murderer must have killed someone somewhere else and then brought the blood and body to this village.

In this way, we can create such a clean scene.

Hearing what Zhao Zhigao said, Lu Chuan nodded, but he still took the ultraviolet scanner and looked around the house carefully.

When it comes to on-site investigation, each person actually gets different things and conclusions.

So even though Zhao Zhigao had said so, Lu Chuan still had to read it himself, otherwise there would be no point in his coming.

"Nothing on the scene has been moved, right?"

Zhao Zhigao nodded affirmatively: "Except for the deceased's belongings being taken away, everything else remains as it was. Nothing has been moved."

After Lu Chuan scanned the area with the ultraviolet scanning light, he indeed found nothing. He returned the tool to Zhao Zhigao and started to work at the edge of the stove.

There was a small stool inside the stove. The murderer must have been sitting on this small stool to add firewood into the stove.

Not far away was a pile of firewood that had not yet burned out.

Lu Chuan walked to the small stool, sat on it, and casually stretched out his left hand towards the pile of remaining firewood.

With his height and arm length, he could easily reach the firewood.

After Lu Chuan stood up, he picked up the notebook and wrote down a few numbers.

Afterwards, Lu Chuan started to work on the firewood pile in the room.

Compared with the interviews outside and the investigation inside, Lu Chuan did a more detailed job this time.

He took each of the remaining firewood, checked it, and numbered it.

"Captain Lu...what are you doing?"

Of course Zhao Zhigao also paid attention to this pile of firewood, but he did not pay too much attention to the details.

Lu Chuan didn't look at Zhao Zhigao who was still busy, but he casually explained to the other party.

"The murderer must have a strong anti-detection awareness. We just checked the room and found that it was handled very cleanly. There are no footprints on the ground."

"And the area along the kang where the deceased's belongings were placed has also been cleaned up."

"But the murderer landed somewhere."

Zhao Zhigao saw Lu Chuan busy with firewood and finally reacted: "You mean firewood?"

Lu Chuan nodded.

“It’s this pile of firewood.”

The crime scene was actually a two-room apartment. After entering the room, there was a kitchen with a stove and a cupboard.

There should have been some water tanks and other things there, but they should have been moved away by the original owners now.

So the house looks very empty inside.

Lu Chuan pointed to a corner in the room.

“The original owner must have stored firewood in that corner.”

Because firewood had been piled up for a long time, the color of the ground in that place was different from that in other places, and there were already some debris left there, which was easy to judge. (End of this chapter)
