Chapter 361 Let’s Talk First

The murderer may have left footprints in the yard, but from the photos, the traces in the yard are too messy. The villagers and officials who came in later basically destroyed the scene in the yard. If you want to do an analysis, you have to go to the scene again to see if you can extract anything useful.

There are no signs of damage or prying on the doors and windows. However, we have to go to the scene to see the specifics. But from the fight between the criminal and the male owner in the living room, the criminal is most likely to enter from the main door.

The murderer entered, threatened, the male owner resisted, was beaten, and then carried into the elderly room downstairs. The whole process should be relatively fast, which can be seen from the blood drops on the ground.

From the victim's own bloody footprints, after his head was broken, he staggered and wanted to escape, and he might have wanted to shout, but then he was injured again. The second blow should be a blunt instrument, a hammer. The speed should be very fast. Judging from the bloodstains thrown on the wall, the murderer is relatively tall, more than 1.8 meters tall, heavy, and very skilled in using a hammer.

Judging from the location of the blows, except for the male owner downstairs, the murderer basically went for the head. The killing was very decisive. It was not an act of forced killing, but should have been premeditated. The surviving baby should have been left behind because he thought there was no threat.

But judging from the subsequent behavior of searching the drawers, the ultimate goal should be to steal money.

There were no valuable fingerprints at the scene, the DNA of the defensive wounds failed to match, and there were very few footprints left, which was very incomplete, indicating that the murderer was experienced.

Jiang Yuan gave a string of information in minutes, and Tang Jia next to him quickly recorded it without being told.

Jiang Yuan combed through the evidence based on bloodstain analysis, footprints, and on-site investigation skills, and Liu Jinghui's thoughts gradually became clear.

After Jiang Yuan finished speaking, Liu Jinghui simply stood up and said from the beginning: The door on the outermost wall of the victim might not be closed, allowing the murderer to enter directly. It is even possible that the door of the villa inside was not closed properly, so the two sides met in the middle of the living room.

However, the male owner of the house probably didn't expect to be killed at first, which means that the other party was not a deep-rooted enemy or creditor.

The old lady upstairs, the eldest son and the hostess should not have heard the sound downstairs, at least not the sound of fighting. Because they were all killed by the sudden murderer in their daily life.

In this way, they may not have wanted to kill people at first, because the male owner resisted and accidentally killed the male owner in the conflict, so they killed the whole family? Of course, it is also possible that they originally had the intention to kill and silence the witnesses, but they did not do it immediately when they just entered the door?

Liu Jinghui made inferences step by step, and tried to describe the crime scene with Jiang Yuan. However, simply looking at the photos, to this extent, basically the analysis is almost the same.

Tang Jia quickly filled several pages with notes.

Let me take a look. Liu Jinghui reached out to take it, read it again, and then underlined the words Jiang Yuan said, "The murderer is relatively tall, more than 1.8 meters tall, heavy, and skilled in using a hammer."

Liu Jinghui smiled and said: Send this to Chiyong City first, they should be interested.

Yes. OK. Jiang Yuan used LV5 bloodstain analysis and LV3 footprint analysis to do this. The analysis report obtained from this is only good enough, even if we ask experts from the ministries to do it. It is unlikely to be achieved.

After all, there are too few experts who understand bloodstain analysis and have practical experience. It is difficult to maintain professional standards. Chiyong City probably can't borrow one or two occasionally.

Crime scene reconstruction, I think we can do it first, and then go back to the scene and do it again. Although Liu Jinghui likes reasoning, he also needs the support of evidence or clues. He likes Jiang Yuan's crime scene reconstruction technology very much.

Reasoning school, what they like most is to restore the original appearance of the case.

Chiyong City.

In the crowded office, there are only the crabapple flowers on the windowsill,

which still stubbornly exude the breath of life. Dozens of cigarette butts were piled in the pot of crabapple flowers, like a moon surrounded by stars.

Yuan Ben faxed the files, sent photos, and helped Wang Chuanxing and others run the procedures before taking a short break. He stood by the crabapple flowers, lit a cigarette, and smoked silently.

Since confirming Jiang Yuan's identity, Yuan Ben has become more diligent and more tired.

Only those who do criminal investigations feel that experts are rare, especially technical experts who can really help solve cases, who are always absolutely scarce.

The number of experts in each province is very limited. There are only a few experts who can make a name for themselves in a province. If they are selected from all over the country, they will be even more scarce.

Don't think that the case in Chiyong seems very important, but to be honest, which criminal case is not important? And an expert focuses on a case, and may plunge into it for several weeks or months, but cases all over the country are happening continuously.

Yuan Ben has been very polite to technical experts in this province recently, not to mention those from other provinces. Dongdong.

Wang Chuanxing knocked on the door of the big office, walked in and said with a smile: They are all here. The policeman who heard the voice nodded to him and pointed to Yuan Ben's position.

Wang Chuanxing also saw it himself, and hurried over, took out a cigarette and handed it to Yuan Ben, saying: I'm sorry to bother you just now, we have almost completed the procedures here.

Just complete the formalities. Yuan Ben smiled.

Thanks to you, otherwise, we would have been delayed for a long time. Just don't let it affect your case.

I'm just a small fry. The family annihilation case is the job of the whole team, and it's not my job today. The director is in charge, and the detachment leader is in charge, so I just have to obey. "Yuan Ben waved his hand.

In fact, one of his jobs was to find and contact various experts. He would be very happy if he could contact Jiang Yuan through Wang Chuanxing and others.

Thinking of this, Yuan Ben whispered: To be honest, there has been no progress in the case so far. Even if we want to use people or send people out to investigate clues, it's useless. Because there are no clues.

Yuan Ben spread his hands and said: We just investigated the neighbors and walked all over the village, but it was useless.

Wang Chuanxing felt a little nostalgic and a little understanding when he heard it, and couldn't help but smile: I understand, we had this situation before. Before?

That is, after following Captain Jiang, this situation Less. Wang Chuanxing smiled and said: Captain Jiang usually screens the clues first and then sends people. There are very few people.

Yuan Ben laughed twice and believed Wang Chuanxing only 30%. Occasionally, one or two cases may be handled easily, but it is unlikely to be easy for most cases. Especially for the backlog of murder cases, logically speaking, none of them are easy.

As he was talking, Wang Chuanxing's cell phone rang.

Wang Chuanxing answered the phone, already smiling, and said: Captain Jiang gave an analysis. Sent a text message, wait a minute. What analysis? Yuan Ben was more curious at this time.

Then, Wang Chuanxing sent the text message Show him.

On the screen, a short sentence read: According to the bloodstain analysis and footprints, one of the murderers is 1.8 meters tall, heavy, and skilled in using a hammer.

A few factors made Yuan Ben swallow his saliva.

Although it is still a very wide range, this is already a very useful clue since the murder. Is this the profile of the murderer given by Captain Jiang Yuanjiang? Yuan Ben asked.

Wang Chuanxing shook his head: It is not a profile. You see, Captain Jiang said that the bloodstain analysis should be based on the blood drops on the wall.

Well, our technicians actually have similar analyses, but they are not very sure. Yuan Ben Wei He shook his head slightly.

One of the problems encountered by Chiyong's task force was that the information received was too mixed and messy, so it was difficult to extract clues.

Looking at Wang Chuanxing, Yuan Ben hesitated for a moment and said: If this is confirmed to be Captain Jiang's judgment, I will report it.

It was Captain Jiang who did it, you report it and see. Wang Chuanxing responded.

Yuan Ben nodded, turned around and made a phone call.

After a while, Yuan Ben turned back excitedly and said to Wang Chuanxing: Our detachment leader wants to talk to your Captain Jiang.

This is our Director Huang's phone number, we can talk first. Wang Chuanxing just got the authorization.
