Chapter 205 Investigation Direction
Doing on-site surveys is Jiang Yuan's old profession.

LV4's on-site investigation, as long as it's not a professional criminal, you can more or less find something.

However, after Jiang Yuan entered the door, the first thing he observed was blood.

His bloodstain analysis is LV5, which is equivalent to a sprinter who can run 10 meters in less than [-] seconds. From the start of the movement, everything has been optimized.

Although no careful identification was made, and there was no time to seriously analyze it, but based on what Jiang Yuan has seen so far, a lot of conclusions can already be drawn.

For example, the bloodstains that Jiang Yuan saw, from the beginning to the end of the murder, the murderer's movements were particularly large.

With such a big move, it is reasonable to say that ordinary site surveyors can find some clues.

Especially for the victim, in the face of fierce attacks, if he resisted a little, he might be able to leave some physical evidence about the murderer.

However, it did not.

In this case, according to Jiang Yuan's understanding, the murderer should have made relatively complete preparations.Gloves are worn, necks are protected, hair is wrapped, etc.

The first thing that came to Jiang Yuan's mind was a murderer wearing a one-piece suit that covered everything including his head, holding a sharp knife, forcing the victim to retreat step by step, and then stabbing... chasing... making up the knife...

During this process, the pitiful counterattack with few victims, even if it scratched the murderer's body, was bounced off by the smooth clothes, and it was impossible to even tear off a little fiber of the clothes.

It's just... such a complete set of equipment has been deliberately made here, why do they use such an outdated method of killing with knives?
Wouldn't it be easier to set fire directly?
It's still 3 o'clock in the morning.

During this period of time, normal people should be sleeping. If the murderer is familiar enough to have the key, he should wipe his neck at night.Although the amount of bleeding will be relatively large, it will not be so large that it will spray everywhere in the room.

Judging from the large amount of blood now, the murderer's preparations were not sufficient at all.

The more Jiang Yuan looked at it, the more he felt conflicted.

At this time, Hou Lejia urged: "Jiang Forensic Doctor, how many assistants can I give you?"

At this time, you can see that different criminal policemen have different styles of doing things.

Hou Lejia is still more of a managerial type. He has his own ideas and stubbornness about the direction of investigation and other criminal investigation content.As for the forensic or criminal staff, he used them purely as a tool, and he didn't listen to their opinions, he just wanted to get his own oriented answers.

In fact, most of the old-school detectives are like this.

Some criminal policemen were taught a lot to be human in the [-]s.At that time, the DNA laboratory was like Aladdin's magic lamp. It could spit out the answers to a few accumulated cases every few days. It didn't need any criminal investigation thinking, no sudden inspiration, let alone staying up late and running. The first generation of DNA technology is as easy as eating hot pot with old oil.

However, no matter how powerful the technology is, there will also be stubborn conservatives.

Hou Lejia needs technology, but he never likes to give the power of direction to the technicians.

Correspondingly, he doesn't care too much about the technician's mistakes, as long as he does what he asks, and he can do it without losing his temper if he makes a mistake.

It's probably the same kind of personality. Only the forensic doctor Ye of Ma Daha and the current survey who started from LV0.6 can live happily.

However, Jiang Yuan doesn't like this model.

In other words, Jiang Yuan, who mastered LV5's bloodstain analysis, didn't like being so obedient in a room full of blood.

Xiaohou is too weak, so his instructions are not so easy to hear.

Jiang Yuan didn't confront him either. After thinking for a while, he turned around and said, "Let's eat something first, I'm too hungry. If we start the survey now, it will take at least five or six hours to finish..."

"Oh, look at my brain." Hou Lejia slapped his forehead and said with a smile: "What do you want to eat? The pork belly chicken with fat intestines last time? That may have to wait for a while, I don't know if it is sold out now..."

"Snail noodles." Jiang Yuan interrupted Captain Hou's self-talk, and said, "Eat a smelly one to cover up the smell."

"Uh, are you going to eat here?"

"Surely you can't eat it at the crime scene, cook it and eat it at the door." Jiang Yuan said.

"It works. Well... Hou Xiaoyong, go get some snail noodles. Is one enough?"

"That's enough, it's not easy to work if you're too full." Jiang Yuan paused, and then told Hou Xiaoyong: "Add a sausage and two eggs."

Taking advantage of the cooking time, Jiang Yuan took out a notebook and began to sketch the images of the crime scene.

Hou Le's family didn't know how to do it, and they couldn't force Jiang Yuan, who hadn't eaten, to clean the floor now, so he could only wait patiently.

After a while, a smell different from that of corpses swept over.

"Jiang Fayi, are you out to eat snail noodles?" Hou Xiaoyong poked his head in.

"Wait for a while." Jiang Yuan gestured twice, went out to take a look, and then came back, saying: "Captain Hou, I have an idea, I want to communicate with you."

Hou Lejia was taken aback, and said, "You said."

"I took a rough look at the crime scene just now and made a relatively simple reconstruction of the crime scene. Let me explain?" Jiang Yuan stood at the door by himself.

"Come on." Seeing this, Hou Le's family agreed.

Jiang Yuan stretched out his hand flatly, and said: "Here, the victim's neck is covered with a dagger, his skin is slightly pierced, and he is being pushed in by the criminal suspect. The direction of these blood drops on the ground is to rush The ones in the bedroom, and they are all slow blood..."

Hou Lejia looked at Jiang Yuan in confusion.

Jiang Yuan continued to walk two steps forward, then turned around, and said, "Here, the murderer made his first attack..."

"The victim may have resisted but was pushed away."

"It can be seen from the blood that the murderer pushed the victim here."

Jiang Yuan went into the bedroom while reconstructing the crime scene.

Then, instead of continuing, he turned around and walked out of the bedroom, returned to the front door, and said, "If you are an acquaintance, at this time of 3 o'clock in the morning, you will be forced to use a knife when you enter the door. Isn't it a bit contradictory?"

Hou Lejia frowned.

"I think it was a stranger who committed the crime." Jiang Yuan rebuilt the crime scene. Although he built a rough version, he can build a detailed version if necessary.

In this case, what Jiang Yuan said was very tough.

Hou Lejia asked: "How did the stranger enter the victim's home at 3 o'clock in the morning?"

"The victim put it in."

"The victim?"

"Yes, I just took a look outside the door. I suspect that the murderer's original purpose may have been just to steal." In recent days, Jiang Yuan has extended the sentences of so many small thieves, and he has a little understanding of their identities.

Hou Lejia didn't believe it, and asked, "What did you steal?"

"Bicycles and motorcycles at the door. Maybe they want to burglarize. Only such a thief can wrap his whole body so tightly."

"Then, the victim came over and opened the door to look?" Hou Lejia began to add knowledge points by himself.

Jiang Yuan nodded: "He was kidnapped and returned."

What Jiang Yuan said made sense, and Hou Lejia began to worry.This has completely changed the direction of investigation.

"If the murderer is a stranger, then the little girl will be at great risk." Forensic Ye said slowly, and everyone's expressions were not very good.
