Chapter 205: Investigation Direction

Doing crime scene investigation was already Jiang Yuan's old trade.

With LV4 Crime Scene Investigation, as long as he wasn't facing a professional criminal, he could more or less find something.

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

His bloodstain analysis was LV5, equivalent to a sprinter running the 100-meter dash in under 10 seconds; from the moment of the starting motion, everything was optimized.

Although he hadn't done a careful identification or had time to analyze it seriously, just from what Jiang Yuan saw, he could already draw many conclusions.

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

With such large movements, logically speaking, ordinary crime scene investigators should have been able to find some clues.

Especially the victim; facing such intense attack movements, if she had resisted even a little, she might have left behind some physical evidence related to the murderer.

However, there was none.

In this situation, according to Jiang Yuan's understanding, it should be that the murderer had made relatively complete preparations. Wearing gloves, the neck was protected, the hair was wrapped up, etc.

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

During this process, the victim's pitifully small resistance, even if she scratched the murderer's body, was deflected by the smooth clothing, and she couldn't even tear off a single fiber of clothing.

It's just... having gone to such lengths to prepare a whole set of equipment, why use a tool as backward as a knife?

Wouldn't arson be simpler?

And it was at 3:00 AM.

At this time, normal people should be sleeping. If the murderer was familiar enough to have a key, they should have slit her throat at night. Although the bleeding would be quite heavy, it wouldn't be enough to spray all over the room.

Judging from the large amount of blood now, the murderer's preparation work was not sufficient at all.

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

Hou Lejia urged at this moment: "Wu Wu Fa Yi Jiang, should we assign you a few assistants or how should we do it?"

At this time, one could see the different working styles of different criminal police officers.

Hou Lejia was still more of a management type; he had his own ideas and stubbornness regarding investigation directions and other criminal investigation content. As for forensic doctors or criminal science personnel, he purely used them as tools, didn't listen to their opinions, and only wanted to get the answers he was oriented toward.

Old-school criminal police officers were actually mostly like this.

Some criminal police officers were taught a lesson by many people in the early 2000s. At that time, DNA laboratories were like Aladdin's lamps, spitting out answers to several cold cases every few days; there was no need for any criminal investigation thinking, no need for any flashes of inspiration, and even less need to stay up late and run around. The first generation of DNA technology was as easy as having hotpot with old oil.

However, even in the face of the most awesome technology, there would be stubborn conservatives.

Hou Lejia needed technology, but he never liked to delegate the power of pointing out the direction to technicians.

Correspondingly, he wasn't very concerned about the mistakes of technicians; as long as they followed his requirements, if they did it wrong, he could also manage not to lose his temper.

It was probably because of this personality that the careless Wu Wu Fa Yi Ye and the LV0.6-starting crime scene investigator could live happily.

However, Jiang Yuan didn't like this mode.

Or rather, Jiang Yuan, who mastered LV5 bloodstain analysis, didn't like being so obedient and listening to orders in a room sprayed with blood.

Little Hou was too weak, so his instructions weren't that easy to listen to.

Jiang Yuan didn't confront him head-on either; he thought for a moment, turned around and said: "Let's eat something first; I'm too hungry. If we start the investigation now, it will take at least five or six hours to finish..."

"Oh my, look at my brain." Hou Lejia slapped his forehead and smiled: "What would you like to eat? The pig intestine and pork stomach chicken from last time? That might take a while to wait for; I don't know if they've set up the stall yet..."

"Luosifen (snail rice noodles) then." Jiang Yuan interrupted the captain's rambling and said: "Eat something smelly to cover up the smell."

"Uh, eat right here?"

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

"That works. That... Hou Xiaoyong, go get some Luosifen. Is one portion enough?"

"Enough, it's not easy to work if you're too full." Jiang Yuan paused, then instructed Hou Xiaoyong: "Add a sausage, add two eggs."

Taking advantage of the time it took to cook the noodles, Jiang Yuan took out a notebook and began to sketch the crime scene.

Hou Lejia didn't know the trade and couldn't force Jiang Yuan, who hadn't eaten, to go scrub the floor now, so he could only wait patiently on the side.

After a while, a smell different from corpse odor swept over.

"Wu Wu Fa Yi Jiang, coming out to eat Luosifen?" Hou Xiaoyong poked his head in.

"Wait a moment." Jiang Yuan gestured a few times, went out to take a few looks, then came back and said: "Captain Hou, I have an idea; let me communicate it with you."

Hou Lejia was stunned and said: "Go ahead."

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

"Go ahead." Seeing this, Hou Lejia agreed.

Jiang Yuan stretched his hands out flat and said: "Here, a dagger was resting on the victim's neck, the skin was slightly pierced, and it was being pushed inward by the criminal suspect. The direction of these blood drops on the ground is toward the bedroom, and they are all slow-speed blood..."

Hou Lejia looked at Jiang Yuan, not understanding.

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 to here."

Jiang Yuan continued the crime scene reconstruction all the way into the bedroom.

Then, he didn't continue, but instead turned and walked out of the bedroom, returned to the front door, and said: "If it were a crime committed by an acquaintance, at 3:00 AM, wouldn't it be somewhat contradictory to force entry with a knife?"

Hou Lejia frowned as he watched.

"I believe it was a crime committed by a stranger." Jiang Yuan had reconstructed the crime scene, although it was a relatively rough version, but if needed, he could build a detailed version.

In this situation, Jiang Yuan spoke very firmly.

Hou Lejia asked: "If it was a stranger, how did they enter the victim's home at 3:00 AM?"

"The victim let them in."

"The victim?"

"Yes, I just looked outside the door; I suspect the murderer's initial purpose might have just been theft." In the past few days, Jiang Yuan had increased the sentences of so many petty thieves that he had an understanding of their status.

Hou Lejia didn't believe it and asked: "Steal what?"

"The bicycle and motorcycle at the door. Maybe they even wanted to commit burglary; only such petty thieves would wrap themselves so tightly."

"Then, the victim came over, opened the door to look?" Hou Lejia began to supplement his own knowledge.

Jiang Yuan nodded: "They were taken hostage and brought back."

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

"If the murderer was a stranger, then the little girl is facing a very high risk." Wu Wu Fa Yi Ye said slowly, and everyone's expression wasn't too good. ===== CHAPTER 206 =====
