Chapter 500 On-Site Reconstruction

noon.

After taking a short rest, Jiang Yuan led 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 as much as possible. Despite this, a large number of broken glass, people jumping from the building, and the sound of gunshots like firecrackers still attracted many people to watch.

In the surrounding buildings, there are still people taking pictures with cameras. So much so that the police from the local police station had to go upstairs frequently to give warnings.

A large number of trace inspections have been working here for two or three hours. The traces in the courtyard wall outside the building are basically collected, and the body that jumped out only left a white circle.

…

Debris on the ground, broken glass and other items that should be collected were also collected.

In the main building, the bodies were also the first to be removed, along with a large number of firearms, firearms, drugs and other items, all packed and sent away.

Even if the Criminal Police Detachment and the Anti-Narcotics Detachment were both in charge, and the Criminal Science Center of Changyang City was involved, the scale of this on-site investigation was far beyond the normal level.

A typical crime scene is the size of a room or a suite, and a case that can kill a whole courtyard is considered a super major case.

The scope of the current survey is one building. Just think about it and you can appreciate the workload involved.

From the moment he walked in the door, Jiang Yuan felt the strong New Year atmosphere——

The smell of gunpowder smoke lingered, and the messy ground was covered with all kinds of footprints. Broken vases, the remains of decorations, and bullet casings and bullet heads were scattered all around.

Most of the bullets used by police are lead-core bullets, which are not easy to rebound when hit by hard objects.

The weapons of drug traffickers are not so particular. There are Hualong weapons that make two shots based on luck, steel-core bullets, and even explosives.

However, most of the drug gang members had no time to show the power of their weapons and were eliminated one by one or surrendered voluntarily.

Even in areas where firearms are prevalent in Europe and the United States, many drug dealers still hold their pistols horizontally and shoot, and the maintenance of the firearms and the accuracy of shooting are impossible to talk about.

Although the drug trafficking gangs in Changyang City have obtained some weapons, their combat qualities are still out of reach.

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

Even if the criminals who have time to surrender are lucky, and those who resist, their situation will not improve at all——

It is very difficult for the police to achieve zero casualties, but the most difficult thing is definitely the opponent.

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

He now also has a +1 bonus to Footprint Identification.

Temporary skill +1 at 405 minutes. There are still more than 100 minutes left. Level 6 skills are not necessary in such a scene, but they are definitely useful.

There is nothing good in the world that is really useless. For the scene in front of you, using lv3 footprint identification or even lv2 footprint identification may be enough, but with high-level footprint identification, it will naturally be better. effect, greater fault tolerance, and higher efficiency.

Jiang Yuan first directed Mu Zhiyang, Wang Chuanxing and others to place signs and take photos. Most of the footprints have not yet been processed, and the direction of the police bridge is mainly towards the corpses. They can just make up for it themselves.

Then, Jiang Yuan listed some more important and identical footprints separately from the first floor to the sixth floor and then from the sixth floor back to the first floor. Just one footprint made Jiang Yuan reach the afternoon.

The footprint identification at level 6 ended on time, and it still feels good to continue using it at level 5.

During the process of identifying the footprints, Jiang Yuan didn't have much to worry about. If there were any unclear areas, he could just deal with them slowly when he went back.

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

This is an advanced version of crime scene reconstruction.

It can't be like blood stain analysis.

You can see the movements of the hands. However, if someone bleeds, the reconstruction of the crime scene can be perfect along with the footprint analysis of the bloodstain analysis.

However, the number of people at a general crime scene is very small, and it is rare for a unit with dozens of people to appear.

There are cases of gang fights, but generally there is no need for crime scene reconstruction.

Jiang Yuan had a vague idea: In this chaotic environment, among the criminals who organized themselves spontaneously, the ones occupying the C position must be the core figures or core management.

At such a tense moment, if you talk about hiding anything, you are just causing trouble for yourself.

But after being arrested, I had enough time and energy to concentrate on surviving.

Jiang Yuan didn't need to report to anyone, he just explored it by himself and thought about it.

"Let's start with this." Jiang Yuan waved Tang Jia over, pointed to the footprints of a middle-aged man with size 42 feet on the ground, and said: "Take a few more pictures of this footprint, and then make a record... Who is that? You take pictures.”

He called an onlooker who was dedicated to taking photos, who should be from the anti-narcotics detachment, and signaled Tang Jia to get ready, and said: "Suspect 1-05, age 42, 42 feet tall, 140 pounds, should have practiced boxing." , it is suspected that the core figure on the first floor was hit in the leg first.”

"At the beginning of the injury, 1-05 crawled a few steps quickly, and his movements were very fast - it can be seen from the trailing degree of the blood-dropped tadpoles."

"Then, the suspect sat on the ground, leaning against two cabinets and firing. He even took a respectful posture in the middle, probably because he was not tall enough. This can be seen from the small pool of blood he left on the ground. The subsequent pool of blood was extended, which also shows that he moved slowly."

"Other criminals provided support to him in the back, numbered 1-06 and 1-07."

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

"1-07 fell to the ground after being injured, and threw the extra magazine to 1-05."

"In terms of the battle in the office area alone, 1-05 was obviously 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, and his brain was sprayed on the wall. The body slid to the ground and shed more blood. Then the others lost their will to fight."

Jiang Yuan stood in front of the pool of blood. In the absence of the body, he narrated the occurrence of this crime scene orally, as if he had seen it in person.

During the operation, there were many people at the scene, and they all carried law enforcement recorders, so crime scene reconstruction was not originally required.

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

The most important thing is that the judgment of the core person cannot necessarily be judged through the image.

In fact, if he was not very cautious or too knowledgeable, the captain of the anti-drug detachment would not have to raise this point with Jiang Yuan.

It is simple and convenient to almost perfect to assume that Huang Li is the leader of the criminal gang.

The anti-drug detachment can directly announce the annihilation of the criminal gang. If the members of the gang cooperate a little more, it will be invincible.

It seems that Captain Yin does not seem to have such an idea, perhaps because he is worried that too many units are involved...

In short, it is necessary to confirm things that are not confirmed beforehand.

Just like being too anxious beforehand and not wearing a condom, it is always better to do an inspection afterwards.

Jiang Yuan is like a reagent. No one knows how he does it, but everyone feels at ease watching him do things.

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

Jiang Yuan walked on the plank bridge and stopped from time to time to make comments.

The captain of the anti-drug detachment hoped that he could find fingerprints at important locations through fingerprints and other methods to prove that certain people were important figures in the drug trafficking gang.

The method and idea were not wrong, but the efficiency was relatively low. Moreover, if it was just to take fingerprints, ordinary criminal officers would actually take them, and it was not necessary for Jiang Yuan to do it.

However, the anti-drug detachment could not do anything like bloodstain analysis and crime scene reconstruction.

It was very easy to judge the core figures.

For example, those who were carried away in the rain of bullets, or those who were shot but not left behind, but were carried, beaten or supported by their companions to evacuate upwards, were either big brothers or brothers.

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

Jiang Yuan did it according to his own ideas. Leaders like Captain Yin certainly understand criminal investigation, and may even understand a little bit about criminal science, but they are essentially Muggles, and it is impossible for them to guide the specific work of criminal science.

Anyway, give them the answer in the end.

Jiang Yuan walked up all the way and soon reached the third floor.

At this time, some people have begun to follow Jiang Yuan's footsteps.

Now is the time for on-site investigation. The Muggles are all resting outside. Those who can stay in the main building are basically criminal science and technical personnel. Some people don't think much when they hear Jiang Yuan say a few words, but as they listen, they slowly start to pay attention.

Level 5 bloodstain analysis, with a little level 4 crime scene investigation, and the assistance of footprints and fingerprints, this strength can actually reduce the intelligence of most ordinary on-site investigators to Muggles.

And those who have a little bit of pursuit will feel very refreshed and refreshed when listening.

Jiang Yuan and others naturally will not stop others from listening. Gradually, Jiang Yuan walked in front, stopping from time to time to let Wang Chuanxing take notes.

And there may be more than a dozen or twenty people taking notes at the same time.

Mu Zhiyang couldn't help but take a photo while watching from the side, and said to himself: It is indeed distributed storage.

Naturally, everyone will ignore the Muggles. The number of cases handled by criminal police at the detachment level is far less than that of the grassroots level.

But in terms of pursuit, the upward space at the grassroots level is extremely limited. Grassroots police are actually the same as primary and secondary school teachers, and basically there will be no promotion in their positions.

But at the first level of the detachment, the pursuit of police officers often has the opportunity to be put into practice.

Even for criminal science technicians, it is always good to learn more.

"Team Leader Yin." Jiang Yuan didn't wait for all six floors to be completed. When he arrived at the fifth floor, he took out his mobile phone after only a few glances.

"How is it, Jiang Yuan, are you done?" Team Leader Yin smiled.

"Not finished, but I am worried that there will be misunderstandings on the interrogation side, so I want to call first." Jiang Yuan directly explained the situation.

Team Leader Yin immediately realized that there was a problem.

He said hurriedly: "You tell me, I'll remember."

"The suspect captured on the third floor is number 17, a 32-year-old male, 1.7 meters tall. He should be the core figure in the drug trafficking gang, at least his status is not less than Huang Li."

Captain Yin asked: "Do you have any evidence?"

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

"I understand." Captain Yin always had the information on the scene, and knew that Jiang Yuan did not adopt his plan, and did not say a word during the on-site survey. After all, he also knew that compared with Jiang Yuan, he was a Muggle.

Now that there is a conclusion, Captain Yin naturally believes in Jiang Yuan's judgment, put away his mobile phone and make arrangements.
