Chapter 473: Crime Scene Reconstruction

Noon.

After a short rest, Jiang Yuan took Mu Mu Zhiyang, Wang Wang Chuanxing, Shen Shen Yaowei, and others into the crime scene centered on the main building.

By this time, the surroundings of the main building had been blocked off as much as possible. Despite this, the large amount of broken glass, the person who jumped, and the firecracker-like gunfire still attracted many onlookers.

In the surrounding buildings, there were still people holding cameras filming, to the point that the local police station's officers had to frequently go upstairs to warn them.

A large number of trace evidence examiners had been working here for two or three hours. The traces within the courtyard wall outside the building had basically been collected, and the body that had leaped out had only left a white outline.

Debris, broken glass, and other items on the ground had also been partially collected.

Inside the main building, the bodies were also the first to be moved away, and a large number of firearms, weapons, and drugs had been packed and sent away.

Even though the Criminal Police Detachment and the Anti-Drug Detachment were responsible simultaneously, and the Changyang City Criminal Science Center was involved, the scale of this crime scene investigation far exceeded normal levels.

An ordinary crime scene is usually at the level of a room or an apartment. A case that can kill everyone in a courtyard is considered a super major case.

The scope of this investigation was an entire building; just thinking about it, one could understand the workload involved.

From the moment he walked through the front door, Jiang Yuan felt the strong atmosphere of the New Year—the smell of gunpowder smoke lingered, the messy ground was covered with all kinds of footprints, broken vases, debris from decorations, and bullet casings and bullet heads were scattered everywhere.

Police bullets are mostly lead-core bullets, which don't easily ricochet when hitting hard objects. The drug traffickers' weapons weren't so particular; there were Hualong-made guns that relied on luck, as well as imported military-grade steel-core bullets, and even explosives could be seen.

However, most of the drug trafficking gang members didn't even have time to show the power of their weapons before they were eliminated one by one or surrendered automatically.

Even in areas where firearms are rampant in Europe and America, many drug dealers shoot pistols sideways, and there is no talk of firearm maintenance or shooting accuracy.

Here in Changyang City, although the drug trafficking gang had acquired some weapons, there was still no talk of combat literacy.

Not to mention that the police were prepared, rushing in in teams according to the training mode with well-trained officers.

Criminals who had time to surrender were lucky. Those who resisted wouldn't see any improvement in their situation—the zero casualties the police wanted were difficult, but the most difficult part was definitely the opponent.

"This workload is a bit large." Jiang Yuan sighed with a smile.

He still had the +1 footprint identification bonus. The 405-minute temporary +1 skill still had over 100 minutes left. An LV6 skill wasn't strictly necessary in a scene like this, but it was definitely useful.

There's no such thing as a good skill that isn't useful. In the scene before him, using LV3 footprint identification, or even LV2, might have been enough, but having higher-level footprint identification naturally yielded better results, greater fault tolerance, and higher efficiency.

Jiang Yuan first directed Mu Mu Zhiyang, Wang Wang Chuanxing, and others to place markers and take photos. Most of the footprints hadn't been processed yet, and the police's bridge-building direction was mainly aimed at the bodies. They just needed to fill in the gaps themselves.

Next, Jiang Yuan singled out some of the more important, identical footprints.

From the first floor to the sixth floor, and then back from the sixth floor to the first floor, just the footprints alone took Jiang Yuan until the afternoon.

The LV6 footprint identification ended on time, and the LV5 continued to feel easy to use.

During the footprint identification process, Jiang Yuan didn't have much to worry about. For the unclear parts, he could deal with them slowly when he went back.

Through the footprints, Jiang Yuan quickly saw the battle process between the two sides during the raid.

This was equivalent to an advanced version of crime scene reconstruction.

It wasn't possible to see the killer's movements like bloodstain analysis. However, if someone bled, combined with footprint analysis and bloodstain analysis, the crime scene reconstruction would be perfect.

However, the number of people at an ordinary crime scene is small, and there are rarely units with dozens of people.

There are fights, but usually, crime scene reconstruction isn't needed.

Jiang Yuan had a vague thought: in this chaotic environment, among the spontaneously organized criminals, the one occupying the C-position must be a core figure or core management.

At such a tense moment, trying to hide anything would purely be looking for trouble for oneself.

Instead, after being arrested, there would be plenty of time and energy to focus on survival.

Jiang Yuan didn't need to report to anyone; he explored on his own and thought while doing so.

"Let's start with this one." Jiang Yuan beckoned Tang Jia over, pointed to a footprint of a middle-aged man with size 42 feet on the ground, and said, "Take a few more photos of this footprint, then make a record... that person, you come and take photos."

He called over a full-time crime scene photographer, who should have been from the Anti-Drug Detachment, and signaled Tang Jia to get ready. "Criminal suspect 1-05, age 42, size 42 feet, 140 jin, should have practiced boxing, suspected to be a core figure on the 1st floor. First hit in the leg."

"At the beginning of the injury, 1-05 crawled a few steps quickly, the movement was fast—you can tell from the trailing degree of the small blood droplets."

"Then, this criminal suspect sat on the ground, relying on two cabinets to shoot, and even adopted a squatting posture at one point, probably because the height wasn't enough. You can tell from the small pool of blood he left on the ground, and the subsequent blood pool elongated, which also shows he moved slowly."

"In the rear, other criminals provided support for him, numbered 1-06 and 1-07."

"1-07 moved forward to support 1-05."

"1-07 was hit and fell, and threw the extra magazine to 1-05."

"Just regarding the battle in the office area, 1-05 was clearly the combat core, but his tactical ability and combat will were not as good as 1-07. This shows that 1-05's status should be higher."

"Finally, 1-05 was hit, his brains sprayed on the wall, the body slid to the ground, and a larger amount of blood flowed out. The others then lost their will to fight."

Jiang Yuan stood in front of the pool of blood and, without the body, narrated the occurrence of the crime scene as if he had seen it with his own eyes.

During the operation, there were many people at the scene, and they were all wearing law enforcement recorders, so crime scene reconstruction wasn't originally needed.

However, the secondary endorsement of crime scene reconstruction is actually very useful when something happens.

The most critical thing is that the judgment of core figures cannot necessarily be determined through images.

Actually, if it weren't for being very cautious or too knowledgeable, the Anti-Drug Detachment leader wouldn't have needed to raise this point to Jiang Yuan.

Defaulting to Huang Li as the head of the criminal gang was simple and convenient to the point of being almost perfect.

The Anti-Drug Detachment could directly announce the annihilation of the criminal gang, and if the gang members were a bit more cooperative, it would be invincible.

It just seemed that Detachment Leader Yin didn't have such a thought, perhaps worried that there were too many units involved...

In short, things that weren't determined beforehand were very necessary to confirm afterwards.

It's like being in too much of a hurry beforehand and not wearing protection; then doing a check afterwards is always better than being sorry.

Jiang Yuan was like a reagent; no one knew how he did it, but watching him work made everyone feel very at ease.

From the first floor to the sixth floor, the inside of the building was in ruins.

Jiang Yuan walked on the bridge boards and stopped from time to time to give commentary.

The Anti-Drug Detachment leader hoped that he could find fingerprints in important locations through fingerprints and other means, thereby proving that certain people were important figures in the drug trafficking gang.

The method and thinking weren't wrong, but the efficiency was relatively low. Moreover, if it were just taking fingerprints, ordinary criminal science personnel could actually take them; it didn't have to be Jiang Yuan.

Instead, things like bloodstain analysis and crime scene reconstruction were things that no one in the Anti-Drug Detachment could do, but they were very good for judging core figures.

Like those who were carried away while bullets were flying, or those who were hit but not left behind, but were carried or supported by companions to retreat upward—if they weren't big bosses, they had to be close brothers.

Even close brothers in a drug trafficking gang might not be able to do this.

Jiang Yuan started working according to his own thinking. Detachment Leader Yin and other leaders were certainly knowledgeable about criminal investigation, and perhaps even a little bit about criminal science, but they were essentially muggles; it was impossible to let them guide the specific work of criminal science.

Anyway, just give them the answer in the end.

Jiang Yuan went upstairs and quickly reached the third floor.

By this time, some people had already started following Jiang Yuan's footsteps.

Now was the time for crime scene investigation, and the muggles were all resting outside. Those who could stay in the main building were basically criminal science and technology personnel. Some people didn't feel anything when they first heard Jiang Yuan say a few words, but as they listened, they slowly began to pay attention.

LV5 bloodstain analysis, combined with a little LV4 crime scene investigation, plus the assistance of footprints and fingerprints, this strength could actually lower the intelligence of most ordinary investigators to muggles.

And those with a little pursuit would feel very refreshing and satisfying when listening.

Jiang Yuan and others naturally wouldn't stop others from listening. Gradually, Jiang Yuan walked in front, stopping from time to time to let Wang Wang Chuanxing make records.

And at the same time, there might be ten or twenty people making records.

Mu Mu Zhiyang couldn't help but take a photo and muttered to himself: It's truly distributed storage.

Everyone naturally wouldn't pay attention to the muggle. The number of cases handled daily by criminal police at the detachment level is far less than that of the grassroots level.

But in terms of pursuit, the room for promotion at the grassroots level is extremely limited. Grassroots police are actually like primary and secondary school teachers; there is basically no promotion in position. But at the detachment level, the pursuit of police officers often has a chance to fall into place.

Even for criminal science and technology personnel, learning a little more is always good.

"Detachment Leader Yin." Jiang Yuan didn't wait for all six floors to be finished. When he reached the fifth floor, he only looked for a few moments before taking out his mobile phone.

"How is it, Jiang Yuan? Are you done?" Detachment Leader Yin smiled.

"Not done, but I'm worried that there will be misunderstandings in the interrogation, so I want to make a call first." Jiang Yuan stated the situation directly.

Detachment Leader Yin immediately realized there was a problem and said busily, "You speak, I'm recording."

"The criminal suspect captured on the third floor, marked here as No. 17, a male about 32 years old, 1.7 meters tall. This person should be a core figure in the drug trafficking gang, at least not lower in status than Huang Li."

Detachment Leader Yin asked, "Is there evidence?"

"Yes, he was in danger twice, and both times he was a more important figure in the team, saved by No. 5. No. 5 should be the core of the team nicknamed 'Nail'. In addition, on the fifth floor, both No. 17 and the team core 'Tea Guest' needed to evacuate, and No. 5 chose to take No. 17 away. 'Tea Guest' was seriously injured and left behind."

"Understood." Detachment Leader Yin always grasped the scene information and knew that Jiang Yuan didn't use his own plan for the investigation, but didn't say anything. After all, he also knew that compared to Jiang Yuan, he was a muggle.

And now that there was a conclusion, Detachment Leader Yin naturally believed Jiang Yuan's judgment, put away his phone, and made arrangements. ===== CHAPTER 474 =====
