Chapter 204 Investigation Direction

Doing on-site investigation is Jiang Yuan's specialty.

Level 4 on-site investigation, as long as the person is not a professional criminal, can find something more or less.

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

His bloodstain analysis is level 5, which is equivalent to a sprinter who runs 100 meters in 10 seconds. From the start, everything is optimized.

Although there is no careful identification and no time for serious analysis, Jiang Yuan can draw a lot of conclusions from what he has seen so far.

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

With such large movements, it stands to reason that ordinary on-site investigators can find some clues.

Especially the victim, facing the fierce attack, a little resistance may leave some physical evidence about the murderer.

However, there is no.

In this case, as far as Jiang Yuan understands, the murderer should have made relatively complete preparations. Wearing gloves, the neck is protected, the hair is wrapped up, etc.

The first thing that came to Jiang Yuan's mind was a murderer wearing a jumpsuit that covered his head, holding a sharp knife, forcing the victim to step back, and then stabbing... chasing... finishing off...

During this process, the victim's pitiful counterattack, even if it scratched the murderer's body, was bounced off by the smooth clothes, and even wanted to tear off a little bit of clothing fiber.

But... after such a deliberate plan to come up with a whole set of equipment, why did they still use such an backward killing method as knives?

Wouldn't it be simpler to set fire directly?

It was still 3 o'clock in the morning.

At this time, normal people should be asleep. If the murderer is familiar with the key, he should have cut the neck at night. Although the amount of bleeding will be relatively large, it will not be so large that it will spray all over 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 contradictions he felt.

Hou Lejia urged at this time: "Forensic doctor Jiang, should I assign you a few assistants or what?"

At this time, we can see the different styles of work of different criminal police.

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 contents. As for forensic doctors or criminal department personnel, he uses them purely as tools, and does not listen to their opinions. He only wants to get the answers he wants.

Old-school criminal police are actually mostly like this.

Some criminal police were taught a lot of lessons in the early 2000s. At that time, the DNA laboratory was like Aladdin's magic lamp, which could spit out answers to several backlog cases every few days. There was no need for any criminal investigation thinking, no need for any sudden inspiration, and no need to stay up late and run. The first generation of DNA technology was as easy to run as eating old oil hot pot.

However, in front of the most powerful technology, there will be stubborn conservatives.

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

Correspondingly, he doesn't care much about the technicians' mistakes. As long as they do what he asks, he won't lose his temper if they make mistakes.

It's probably because of this character that the careless forensic doctor Ye and the on-site investigator who starts at level 6 can live a fulfilling life.

However, Jiang Yuan doesn't like this mode.

Or rather, Jiang Yuan, who has mastered the bloodstain analysis at level 5, doesn't like to be so obedient in a room full of blood.

Xiao Hou is too weak, so his instructions are not so pleasing to the ear.

Jiang Yuan didn't argue with him. After thinking for a while, he turned around and said, "Let's eat something first. We're so hungry. If we start the investigation now, it will take at least five or six hours to finish..."

"Oh, look at my brain." Hou Lejia slapped his forehead and laughed, "What do you want to eat? The pig intestines and pig stomach chicken from last time? That may take a while. I don't know if it's open now..."

"Snail noodles." Jiang Yuan interrupted Captain Hou's monologue and said, "Eat something smelly to cover up the smell."

"Uh, are we going to eat here?"

"You definitely can't eat at the crime scene. Eat it at the door after it's cooked." Jiang Yuan said.

"Okay. That... Hou Xiaoyong, go get some snail noodles. Is one serving enough?"

"Enough. It's hard to work if you're too full." Jiang Yuan paused and told Hou Xiaoyong, "Add a sausage and two eggs."

While the noodles were cooking, Jiang Yuan took out a notebook and began to sketch the image of the crime scene.

Hou Lejia didn't know much about it, and couldn't force Jiang Yuan, who hadn't eaten yet, to mop the floor now, so he could only wait patiently.

After a while, a stench different from the stench of a corpse swept over.

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

"Wait a moment." Jiang Yuan gestured twice again, went out to take a few glances, and then came back and said, "Captain Hou, I have an idea, let me communicate with you."

Hou Lejia was stunned and said, "You tell me."

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

"Come on." Seeing this, Hou Lejia agreed.

Jiang Yuan stretched out his hand flatly and said, "Here, there is a dagger on the victim's neck, the skin is slightly punctured, and the suspect is pushing him in. The direction of the blood drops on the ground is facing the bedroom, and they are all slow blood..."

Hou Lejia looked at Jiang Yuan in confusion.

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

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

"From the bloodstains, it can be seen that the murderer pushed the victim here."

Jiang Yuan reconstructed the crime scene all the way and entered the bedroom.

Then, instead of continuing to talk, he turned around and walked out of the bedroom, returned to the front door, and said, "If it was an acquaintance, at 3 a.m., he was forced with a knife when he entered the door. Isn't it a bit contradictory?"

Hou Lejia frowned and watched.

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

In this case, Jiang Yuan's words were very tough.

Hou Lejia asked: "If it was a stranger, how could he get into the victim's house at 3 o'clock in the morning?"

"The victim put it in."

"The victim?"

"Yes, I just looked outside the door, and I suspect that the murderer's original purpose might just be stealing." In recent days, Jiang Yuan has increased the sentences of so many petty thieves, and he has some understanding of their identities.

Hou Lejia didn't believe it and asked: "What did they steal?"

"The bicycles and motorcycles at the door. Maybe they want to break into the house and rob. Only such petty thieves will wrap themselves so tightly."

"Then, the victim came over and opened the door to see?" Hou Lejia began to supplement his knowledge points.

Jiang Yuan nodded: "She was kidnapped back."

Jiang Yuan's words made sense, and Hou Lejia began to worry. This completely changed the direction of the investigation.

"If the murderer is a stranger, then the little girl is at great risk." Forensic Doctor Ye said slowly, and everyone's expression was not very good.
