Chapter 473: The Crime Scene

Noon.

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

At 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 off the building, and the firecracker-like gunfire still attracted many onlookers.

In the surrounding buildings, there were still people holding cameras and filming. So much so that the police from the local police station had to go upstairs frequently to issue warnings.

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

Items such as debris and broken glass on the ground had also been partially collected.

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

Even if the Criminal Police Detachment and the Anti-Drug Detachment were responsible at the same time, and the Changyang City Criminal Science Center participated, the scale of this crime scene investigation far exceeded the normal level.

A normal crime scene is at the level of a room or an apartment. A case that can kill everyone in a Sihe Academy is already considered a super major case.

The scope of this on-site investigation was a whole 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 didn't dissipate, the messy ground was full of various footprints, broken vases, debris of decorations, and bullet casings and bullet heads were scattered all around.

Police bullets are mostly lead-core bullets, which are not easy to ricochet when hitting hard objects. The drug traffickers' weapons weren't so particular. There were Hualong-made guns that relied on luck to fire, as well as imported military weapons with steel-core bullets, and one could even see the presence of explosives.

It's just that 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 regions where firearms are rampant in Europe and America, there are still many drug dealers who hold pistols sideways to shoot, and there is no talk of firearm maintenance or shooting accuracy.

Placed here in Changyang City, although the drug trafficking gang had managed to get some weapons, as for combat literacy, it was still out of the question.

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

Criminals who had time to surrender were considered lucky. For those who resisted, it wouldn't improve their own situation in the slightest—the zero casualties the police wanted were very 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 footprint identification +1 bonus. The 405-minute temporary skill +1 still had over 100 minutes left. In a scene like this, an LV6 skill wasn't necessary, but it would definitely come in handy.

There is nothing in the world that is truly useless. In the scene before him, using LV3 footprint identification, or even LV2 footprint identification, might have been enough, but having high-level footprint identification would naturally have better results, greater fault tolerance, and higher efficiency.

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

Next, Jiang Yuan listed some of the more important, identical footprints separately.

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

The LV6 footprint identification ended on time, and the LV5 one still felt easy to use.

In the process of footprint identification, Jiang Yuan didn't have much to worry about. For some unclear parts, he could just go back and process them slowly.

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 was impossible to see the killer's movements like bloodstain analysis. However, if someone was bleeding, combined with the footprint analysis of bloodstain analysis, the crime scene reconstruction would be perfect.

However, the number of people at a normal crime scene is very small, and there are rarely units of 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 layer.

At such a tense moment, to say anything about hiding was purely looking for trouble for oneself.

It was only after being arrested that there was plenty of time and energy to focus on seeking survival.

Jiang Yuan didn't need to report to anyone; he just explored on his own and thought about it by the way.

"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 someone, you come and take photos."

He called a full-time on-site investigation photographer, who should be from the Anti-Drug Detachment, and signaled Tang Jia to be ready, saying: "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 also crawled a few steps quickly, the movement was fast—you can tell from the tailing degree of the blood droplets."

"Next, this criminal suspect sat on the ground, relying on two cabinets to fire and shoot. In the middle, he even adopted a squatting posture, probably because the height wasn't enough. This can be seen from a small pool of blood he left on the ground. The subsequent blood pool lengthened, which also shows that he moved slowly."

"There was support from other criminals in the rear, numbered 1-06 and 1-07."

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

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

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

"Finally, 1-05 was hit, a brain full of brains sprayed on the wall, the corpse slid to the ground, flowing out a larger amount of blood, and the others then lost their fighting will."

Jiang Yuan stood in front of the pool of blood and, in the absence of a corpse, dictated the process of the crime scene as if he had seen it himself.

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

However, the secondary endorsement of crime scene reconstruction is actually very useful when things happen.

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

Actually, if it weren't for being very cautious, or too knowledgeable, the Detachment Leader of the Anti-Drug Detachment wouldn't have had to propose this point to Jiang Yuan.

Defaulting that Huang Li was the leader of the drug trafficking gang was simple and convenient to the point of being almost perfect.

The Anti-Drug Detachment could directly announce the annihilation of the drug trafficking gang. If the gang members cooperated a bit more, it would be invincible.

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

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

It's like being too anxious beforehand and not wearing a condom, so it's always good to have a check afterwards just in case.

Jiang Yuan was like a reagent. No one knew how he did it, but watching him work, everyone felt very at ease.

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

Jiang Yuan stepped on the bridge and walked inside, stopping from time to time to comment.

The Detachment Leader of the Anti-Drug Detachment hoped that he could find out the fingerprints of important locations through fingerprints and other means, thereby proving that some 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 was just purely taking fingerprints, ordinary criminal science personnel would actually take them; it didn't have to be Jiang Yuan.

It was bloodstain analysis and crime scene reconstruction that no one in the Anti-Drug Detachment could do, but it was very good for judging core figures.

Like those who were carried while running amidst the rain of bullets, or those who were hit but not left behind, but were carried or supported by companions to retreat upwards, if they weren't big bosses, they had to be own brothers.

Own brothers in a drug trafficking gang might not even be able to do this.

Jiang Yuan did it according to his own thinking. Detachment Leader Yin and other leaders were certainly knowledgeable about criminal investigation, and might even know a little 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 all the way up and quickly reached the third floor.

At this time, someone had already started following Jiang Yuan's footsteps.

Now was the time for on-site investigation. The Muggles were all resting outside. Those who could stay in the main building were basically criminal science technical personnel. Some people didn't feel anything when they heard Jiang Yuan say a few words, but as they listened, they slowly started 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 on-site investigations into Muggles.

And those with a little pursuit would feel refreshed and very happy as they listened.

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

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

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 Muggles. The number of cases handled daily by criminal police at the detachment level is far less than that of front-line grassroots.

But in terms of pursuit, the room for promotion at the grassroots level is extremely limited. Grassroots police are actually the same as 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 technical 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 phone call first." Jiang Yuan stated the situation directly.

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

"The criminal suspect captured on the third floor, marked as number 17 here, a male around 32 years old, 1.7 meters tall. This one should be a core figure in the drug trafficking gang, at least his status is no lower than Huang Li."

Detachment Leader Yin asked: "Is there evidence?"

"En, he was in danger twice, both times as a relatively important figure in the team, saved by number five. Number five should be the core of the team nicknamed Nail. In addition, on the fifth floor, number 17 and the team core figure Tea Guest both needed to retreat, and number five chose to take number 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 plan for on-site investigation, but he didn't say anything. After all, he also knew that compared to Jiang Yuan, he belonged to the Muggles.

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