This time, without waiting for Wang Chuanxing to express his opinion again, Jiang Yuan said again: "Let's talk about the blood stains next. I think this one is more important."

Jiang Yuan quickly found a few photos, then squatted in front of the door and said, "Let's not talk about other parts. Judging from the photos taken, the most important point is that there are gaps in the splash pattern here.

…”

Jiang Yuan circled a space at the crack of the door. He stood a little further in front and said: "Based on the forensic autopsy report, I believe that the murderer was standing where I was at that time, and his waist and legs were spattered with blood.

, which is equivalent to throwing away a strip. That’s why there is a small amount of blank space at the door gap.”

Wang Chuanxing carefully looked at the pictures on Jiang Yuan's phone and the location of the crack in the door, but found nothing.

This is the difficulty level of the third small question, which is the penultimate big question. It can be challenged at a level of 400 to 500 points, but it usually takes 600 points to solve it.

This case is somewhat special. The Changyang City Criminal Police Detachment probably has not assembled the most suitable investigation team. It is normal that the blood stain analysis was not done well.

In today's criminal police force, few people are good at bloodstain analysis.

What's more, the blood stains in this case were relatively small, and many on-site investigators probably did not consider this aspect.

Wan Baoming asked calmly: "If the murderer's position is indeed like this, it means that after the victim opened the door, the murderer took two steps in. This social distance is a bit close."

Jiang Yuan nodded slowly: "So, the murderer is probably an acquaintance. Moreover, considering that his clothes and shoes are stained with blood, it is very inconvenient to take public transportation. There is a high possibility that he lives nearby."

A gust of wind blew from behind, causing several people to get goosebumps.

Wang Chuanxing got excited and asked, "What about the sound of reading the electric meter? If it is a nearby resident, wouldn't anyone who sees him recognize him at a glance?"

"The meters of other houses were not read, which means that the victim was probably the first one to be asked to open the door. Based on this calculation, the murderer probably only shouted a few times when he called for the meter to be read." Jiang Yuan paused and said:

"I can't explain the witness testimony at the moment, but I think we should first follow the clues of blood stains and footprints to investigate."

Wan Baoming said at this time: "You can put aside the witness statements for now. These are all neighbors. Before the police arrived, they had been gathering at the scene for a long time. There were many cases of mutual influence or hints, not to mention the witnesses of this case.

They are all elderly people, and the case happened during nap time..."

Wang Chuanxing was a little unconvinced and didn't know how to refute for a while.

Jiang Yuanze said: "For now, regardless of the number, I suggest that we make a list of nearby residents, and then find out those who are not at the scene after the police arrive, and we can visit them."

Wan Baoming couldn't help but nod: "The murderer has to return to his residence, change and dispose of the bloody clothes, the murder weapon, and maybe take a shower, but he can't go to the scene in a short time."

"I saw the list of people who made the transcript yesterday. I'll look for it." Wang Zhong finally found something he could do, and he took out his notebook and started working on it.

Wang Chuanxing looked at the actions of several people, feeling uncomfortable, and asked in a low voice: "What... what should we do if we interview the murderer?"

"Then let's arrest him." Wei Zhenguo nodded his hands.
