National Forensic Doctor

On-site investigation is Jiang Yuan's specialty.

During LV4's on-site investigation, as long as they are not professional criminals, they can more or less find something.

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

His blood stain analysis is at LV5, which is equivalent to a sprinter running 100 meters within 10 seconds. From the starting action, everything is optimized.

Although he did not make a careful identification and did not have time to analyze it carefully, from what Jiang Yuan has seen so far, he can already draw a lot of conclusions.

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

Logically speaking, for such a big move, ordinary on-site investigators would be able to find some clues.

Especially for the victim, if he resists a fierce attack, he may be able to leave some physical evidence about the murderer.

However, no.

In this case, from Jiang Yuan's understanding, the murderer should have made relatively complete preparations. Gloves were worn, necks were protected, hair was wrapped, etc.

The first thing that came to Jiang Yuan's mind was a murderer wearing a jumpsuit, including his head, holding a sharp blade, forcing the victim to retreat step by step, and then stabbing... chasing... finishing...

During this process, the victim's pitiful counterattacks, even if they scratched the murderer's body, were bounced away by the smooth clothing, and they couldn't even tear off any fiber of the clothing.

It's just... If you have deliberately created a complete set of equipment here, why do you still use such a backward killing method as knives?

Wouldn't it be easier to just set fire to it?

It's still 3 o'clock in the morning.

At this 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 stains, the murderer's preparations were not adequate at all.

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

Hou Lejia urged at this time: "Forensic Doctor Jiang, how many assistants can I assign you or what?"

At this time, you can see the differences in the working styles of different criminal police officers.

Hou Lejia is still relatively managerial. He has his own ideas and stubbornness regarding the direction of investigation and other criminal investigation content. As for the forensic doctors or criminal department personnel, they are purely used as tools and do not listen to their opinions. They only want to get their own answers.

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

Some criminal police officers received a lot of training in their early years. At that time, the DNA laboratory was like Aladdin's magic lamp. It could spit out answers to several backlogged cases every few days. It did not require any criminal investigation thinking, no sudden inspiration, and no need to stay up late and run. The first generation of DNA technology was as easy as eating old oil hot pot.

However, no matter how awesome the technology is, there will always be die-hard 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 technician's mistakes. As long as he follows his requirements, he will not lose his temper if he makes a mistake.

It is probably because of this kind of character that Madaha's forensic doctor Ye and Xian Kan, who started in 6, can live a fulfilling life.

However, Jiang Yuan didn't like this model.

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

Xiao Hou is too weak, and his instructions are not so easy to hear.

Jiang Yuan refused to be tough with him. He thought for a moment and turned around and said, "Let's eat something first. I'm so hungry. If we start the survey now, it will take at least five or six hours to complete..."

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

"Let's eat snail noodles." Jiang Yuan interrupted Captain Hou's monologue and said, "Eat something smellier to cover up the smell."

"Uh, do you want to eat here?"

"You definitely can't eat it at a crime scene. Let's eat it at the door after it's been cooked." Jiang Yuandao.

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

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

The Hou Le 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 they could only wait patiently.

After a while, a stench that was different from corpse stench swept over him.

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

"Wait a moment." Jiang Yuan gestured a few more times, went out to take a look, then came back and said, "Captain Hou, I have an idea that I want to share with you."

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

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

"You come." Seeing this, the Hou Le family 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 he is being pushed in by the suspect. The direction of the blood drops on the ground is the direction of the attack. They are in the bedroom, and they all have slow blood..."

The Hou Le family looked at Jiang Yuan without knowing why.

Jiang Yuan continued to take 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 stains that the murderer pushed the victim here."

Jiang Yuan reconstructed the crime scene and entered the bedroom.

Then, he did not continue talking, but turned around and walked out of the bedroom, returned to the door, and said, "If he is an acquaintance, at 3 o'clock in the morning, he will force him with a knife when he enters the door. Isn't it a bit contradictory?"

Hou Lejia frowned and looked at it.

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

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

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

"The victim put it in."

"Victim?"

"Yes, I just looked outside the door. I suspect that the murderer's original purpose was probably just stealing." In recent days, Jiang Yuan has increased the sentences of so many young thieves, and he has gained an understanding of their status.

The Hou Le family didn't believe it and asked, "What are you stealing?"

"There are bicycles and motorcycles at the door. Maybe they want to break into the house. Only such a little thief would be so tightly wrapped."

"Then, the victim came over and opened the door to take a look?" Hou Lejia began to add knowledge on his own.

Jiang Yuan nodded: "He was kidnapped and came back."

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

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