Chapter 500 On-Site Reconstruction
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 were covered as much as possible. Even so, a large number of broken glass, people who jumped from the building, and the sound of gunfire like firecrackers still attracted many people to watch.

In the surrounding buildings, there are still people holding up their cameras to take pictures.So much so that the police at the local police station had to go upstairs to warn them frequently.

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

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

In the main building, the corpses were also the first to be removed, as well as a large number of firearms, firearms and drugs, all packed away.

Even if the criminal police detachment and the anti-drug detachment were in charge at the same time, and the Criminal Science Center of Changyang City participated, the scale of this on-site investigation far exceeded the normal level.

A general crime scene is the level of a room and a flat, and a case that can kill a courtyard house is considered a super major case.

The scope of this current survey is a building, and you can understand the workload if you think about it.

From the moment he entered the gate, Jiang Yuan could feel the strong atmosphere of the Chinese New Year—the smell of gunpowder smoke could not go away, and the messy ground was full of various footprints, broken vases, residues of decorations, and bullets Shells and bullets, all around.

The bullets used by the police are mostly lead-core bullets, which are not easy to rebound when they hit hard objects.The weapons used by drug traffickers are not so particular. There are Hualong-made two-shot guns based on luck, steel-core bullets flow into arms, and even explosives can be seen.

It's just that most of the drug gang members were wiped out one by one before they could show the power of their weapons, or surrendered automatically.

Even in areas where guns are abundant in Europe and the United States, there are still many drug dealers who shoot sideways with pistols, and the maintenance of guns and the accuracy of shooting are out of the question.

Here in Changyang City, although the drug gangs have acquired some weapons, they still can't talk about their combat literacy.

Not to mention that the police are prepared, with well-trained police officers, according to the training mode, rushed in in groups.

Even if the criminals who have time to surrender are lucky, those who resist will not improve their own situation in the slightest. It is very difficult for the police to achieve zero casualties, but the most difficult thing must be the opponent.

"This workload is a bit heavy." Jiang Yuan smiled and sighed.

He now also has a +1 bonus for Footprint Appraisal. Temporary skill +405 for 1 minutes, and there are more than 100 minutes left at this time. LV6 skills are not necessary in such a situation, but they are definitely useful.

There is nothing good in the world, and it is really useless. For the scene in front of you, the footprint identification of LV3 or even the footprint identification of LV2 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 pictures.Most of the footprints have not been dealt with in time, and the direction of the bridge built by the police is mainly directed at the corpses, so they can fill them in by 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, Jiang Yuan made it through the afternoon with just one footprint.

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

In the process of footprint identification, Jiang Yuan didn't have much to worry about, some unclear points, just go back and deal with them slowly.

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

It's an advanced version of crime scene reconstruction.

It's impossible to see the murderer's movements like bloodstain analysis.However, if someone is bleeding, combined with the footprint analysis of bloodstain analysis, the reconstruction of the crime scene is perfect.

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 gang fights, but generally there is no need for crime scene reconstruction.

Jiang Yuan had a vague idea: in this panic environment, among the criminals organized spontaneously, the core person or core management must occupy the C position.

At such a tense moment, if you want to talk about hiding something, you are simply asking for trouble for yourself.

But after being arrested, I have enough time and energy to concentrate on living.

Jiang Yuan didn't need to report to anyone, so he explored first by himself and thought about it by the way.

"Let's start with this." Jiang Yuan beckoned Tang Jia over, pointed to the footprint of a 42-foot middle-aged man on the ground, and said, "Take a few more pictures of this footprint and make a record... Who, You come to take pictures."

He called a full-time photo shooter, who should be from the anti-drug detachment, and motioned Tang Jia to get ready, and said: "The criminal suspect is 1-05, age 42, 42 feet, 140 catties, and should have practiced boxing. , suspected to be the core figure on the first floor. He was hit in the leg first."

"At the beginning of the trauma, 1-05 crawled a few steps quickly, and the movement was very fast - it can be seen from the trailing degree of the blood drop tadpole."

"Then, the suspect was sitting on the ground, leaning on two cabinets to shoot, and at one point squatted in the middle, probably because he was not tall enough. This can be seen from the small puddle of blood he left on the ground , the follow-up pool of blood was lengthened, which also showed that he was moving slowly."

"Supported by other criminal elements in the rear, numbers 1-06 and 1-07."

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

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

“单就办公区的战斗来说，1-05是明显的战斗核心，但其战术能力和战斗意志都不如1-07。说明1-05的地位应该更高。、”

"In the end, 1-05 was hit, and his head was 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."

Standing in front of the pool of blood, Jiang Yuan dictated what happened at the crime scene without a corpse, as if he had witnessed it himself.

During the battle, there were a lot of people at the scene, and they all wore law enforcement recorders. Originally, there was no need for crime scene reconstruction.

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

The most important thing is that the judgment of the core characters may not necessarily be judged through the image.

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

By default, Huang Li is the leader of the criminal gang, which is so simple and convenient that it is almost perfect.

The anti-drug detachment can directly declare that the criminal gang has been wiped out. If the members of the gang cooperate a little more, they will be invincible.

It just seems that Captain Yin doesn't seem to have such an idea, maybe he is worried that there are too many units involved...

All in all, if there is no certainty in advance, it is also necessary to confirm afterwards.

It's as if I was too anxious beforehand and didn't wear a condom. It's always good to have a checkup after the event to be prepared.

Jiang Yuan is like a reagent, and no one knows how he does it, but watching him do things makes everyone feel at ease.

From the first floor to the sixth floor, the building is dilapidated.

Jiang Yuan stepped on the bridge and walked in, stopping from time to time to make comments.

The detachment leader of the anti-narcotics detachment hoped that he could find out the fingerprints of important places through fingerprints and other methods, so as to prove that certain people were important figures in the drug gang.

The method and idea are also correct, but the efficiency is relatively low. Moreover, if the fingerprints are simply taken, the ordinary criminal staff will actually take them, and it is not necessary for Jiang Yuan to do it.

On the other hand, bloodstain analysis and crime scene reconstruction, none of which can be done in the anti-narcotics detachment, is very easy to judge the core characters.

Like those who were led away amidst the rain of bullets, or those who were shot but were not kept, but were evacuated upwards by their companions or carried or supported. They were not big brothers but also brothers.

Brothers in the drug gang may not be able to do this.

Jiang Yuan followed his own way of thinking.Chief Yin and other leaders certainly understand criminal investigation, and maybe a little bit of criminal science, but they are Muggles in nature, and it is impossible to let them guide the specific work of criminal science.

Anyway, give them the answer in the end.

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

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

Now is the time for on-site investigation. The Muggles are resting outside. Those who can stay in the main building are basically criminal science and technology personnel. Some people don’t think so after hearing what Jiang Yuan said. , and slowly began to pay attention.

LV5's bloodstain analysis, combined with LV4's crime scene investigation, and the assistance of footprints and fingerprints, this ability can actually turn most ordinary investigations into Muggles.

But if you are a little pursuing, you will feel refreshed and refreshed when you listen to it.

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

At the same time, there may be a dozen or twenty people who are recording at the same time.

Mu Zhiyang couldn't help but took a photo while watching, and said to himself: It is true that it is distributed storage.

Naturally, everyone ignored Muggles.Criminal police at the level of the detachment, the number of cases they do daily is far less than that of the first-line grassroots.

But in terms of pursuit, the room for improvement at the grassroots level is extremely limited. In fact, grassroots policemen are the same as primary and secondary school teachers, and basically they will not be promoted in their positions.But at the detachment level, the pursuit of the police often has a chance to be realized.

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

"Yin Detachment." Jiang Yuan didn't wait for all six floors to be finished, and when he reached the fifth floor, he took out his mobile phone after only a few glances.

"How about it, Jiang Yuan, are you done?" Yin Detachment laughed.

"It's not finished, but I'm worried that there may be misunderstandings during the interrogation, so I want to call first." Jiang Yuan directly explained the situation.

Captain Yin immediately realized that there was a problem, and hurriedly said: "You tell me, I will remember."

"The suspect captured on the third floor is number 17, a male about 32 years old, 1.7 meters tall. This should be the core figure in the drug gang, at least not inferior to Huang Li."

Captain Yin asked, "Is there any evidence?"

"Well, he was in danger twice, both of which were important members of the team, and No. 17 rescued him. No. 17 should be the core figure of the team nicknamed Nail. In addition, on the fifth floor, No. [-] and the core of the team All the tea drinkers needed to evacuate, and No. [-] chose to take away No. [-]. The tea guest was seriously injured and was left behind."

"Understood." Detachment Captain Yin always grasped the on-site information, knowing that Jiang Yuan did not adopt his own plan for the site survey, and did not say a word. After all, he also knew that compared with Jiang Yuan, he belonged to Muggles.

But now that he had a conclusion, Captain Yin naturally believed in Jiang Yuan's judgment, put away his phone and made arrangements.
