Chapter 889 Entering the scene
Jiang Yuan happily received the first-class merit medal, posted a message on his Moments, got into Song Tiancheng's car, drove straight to the airport, and flew to Hubei Jiangsu Province.

Wang Chuanxing and others naturally had no time to rest. After handing over their work, they followed Jiang Yuanfei.

While on the plane, Jiang Yuan selected the skill of "Trace Inspection - Explosion Trace Inspection (LV6)".

It's different to follow the leaders of the ministry, especially those at Song Tiancheng's level. The barefoot immortal has come down to earth, and ordinary people still want to use their existing skills to beat the whole game, which is a very dangerous idea.

Furthermore, although the application scope of explosion traces is not as wide as that of skills such as tool mark inspection, in terms of Jiang Yuan’s current technical map, explosion trace detection can be regarded as filling a large gap.

In today's society, there are many applications for explosion trace detection. In addition to typical explosions caused by explosives, some unconventional explosions also occur from time to time. Common examples include explosions at fire scenes, explosions of materials in kitchens, gas tanks, and natural gas pipelines, explosions in industrial and mining enterprises, and illegal explosives made by individuals. Similar cases still occur from time to time, and the harm is relatively large.

Jiang Yuan clicked on the skill and felt much more at peace.

The LV6 skill can be regarded as god-level, and it can also be temporarily +1. It can be said that when you arrive at the scene, no matter it is the awesome Monkey King or the awesome Monkey King, you can analyze it a little.

In comparison, Song Tiancheng was not so at ease. He took Jiang Yuan and greeted the leaders from the Hubei and Jiangsu Provincial Departments who came to greet them at the airport. After only three minutes of conversation, he got in the car and rushed to Hanshui Town where the crime occurred. The journey took another two hours.

When we arrived, it was already afternoon and it was about to get dark.

"What do you think? There's still an hour and a half left until dark. Will we make it in time?" Song Tiancheng asked a little worriedly.

"I've read it once. If necessary, I can finish it at night by lamplight." Jiang Yuan came here with emotional intelligence. Now that he doesn't need his IQ, he will show it off.

Song Tiancheng's anxious mood was relieved to a certain extent. He smiled like an immortal again and said, "It's good that we made it in time. By the way, you have worked on an explosion scene before, right? Do you have any research in this area?"

"Yes. Don't worry." Jiang Yuan had actually worked on an explosion scene, but at that time he used crime scene investigation to investigate. The purpose of the investigation was to find evidence at the crime scene and reconstruct the interaction between people and objects in time and space.

The inspection of explosion traces is different. It focuses on the explosion itself, emphasizes the center of the explosion, and performs analysis on the amount of explosives, the type of explosion, and the nature of the explosion. It determines the original form of the explosive device, and then conducts a comprehensive analysis to characterize the perpetrator's characteristics, etc., thereby providing information and evidence for solving the case.

To master this technology, one needs mechanical analysis, deformation and stress analysis, as well as theoretical knowledge of physics, chemistry, explosion dynamics, etc.

However, there is one good thing about science knowledge: although it is hard to learn, it is very reassuring to use. Naturally, if the learning process is also omitted...

Song Tiancheng looked at Jiang Yuan with satisfaction. Nowadays, subordinates who dare to make their leaders feel at ease are all good subordinates.

on site.

The bright yellow warning tape stretched out hundreds of meters away.

The most eye-catching thing was the broken glass all over the ground. Starting from the cordon, one could see broken glass like hail. Jiang Yuan and others changed into new police boots before continuing to enter.

The people led by the barefoot immortal must be wearing new shoes.

The closer you get to the central area, the more you can see the mess of explosion debris, shattered glass, flying rocks, and garbage of unknown origin.

The most central location, where the explosion occurred, was a car repair shop building, which had been reduced to semi-ruins. It can be said that the explosion was extremely powerful.

"The explosion site was an underground gambling house in the town. At the time of the incident, there were an estimated thirty to forty people gambling inside, and more than a dozen of them were the gambling house owner's men. The current confirmed death toll is 11, and the number of injured has exceeded 30." Accompanying them was Wang Sheng, captain of the Meiyang City Criminal Police Detachment.

Hanshui Town, where the crime took place, is a marginal town in Meiyang City. Routine cases are handled by the police station, but a case of this magnitude can only be taken over by the superior criminal police detachment.

"What have you discovered so far?" It was Song Tiancheng who asked the question. Everyone at the scene was under a lot of pressure, and Song Tiancheng was no exception.

Wang Sheng had the appearance of a scholar with a pale face. He showed a helpless expression at this moment and said, "We initially locked on a suspect, a player who often lost money in the gambling house, a small boss in the engineering industry, who had access to explosives. But after investigation, we found that he did not have the time and motive to commit the crime. At present, there is no second suspect."

Song Tiancheng said "hmm".

Wang Sheng went on to explain: "There is another problem now. Because the explosion at the scene was so violent, the identity of the victim has not yet been fully determined. Therefore, the suspects cannot be listed clearly..."

Song Tiancheng was a big shot of some rank, and he could tell something was wrong as soon as he heard it, and said, "Doesn't that mean that the number of the dead and the number of the victims have not been determined?"

"Well... there are indeed doubts." After all, Wang Sheng was not a direct subordinate of the Barefoot Immortal. He sighed and said, "You will know after seeing the scene. The scene is a mess and it is very difficult to judge."

"Let me go into the scene first." Jiang Yuan had already dressed up. He called two of his men and went into the building first.

The auto repair shop that had been bombed to pieces was made of prefabricated panels, and now half of it had collapsed, looking like the ruins in a war-torn area shown on TV news.

But the scene when you walked in was something that could not be shown on TV, especially after you walked around the half-ruined building, a large number of blood-colored objects began to impact your vision.

In such an environment, even police officers who often go to the scene cannot immediately distinguish which are pieces of meat and which are stones stained with blood.

However, Jiang Yuan didn't need to look very carefully to know that most of them were blood-stained building materials, stones, glass, etc. Real pieces of meat would not explode so far.

Jiang Yuan took a quick glance and waited for the photographer behind him to take pictures and record videos before continuing to go inside.

The innermost office is the core area of ​​this gambling house, and it also seems to be the most tragic place.

Red blood, white broken bones, and a large amount of soaked clothing were the main colors on the ground. The body had been taken away. Jiang Yuan came to help as an expert. The local criminal police detachment was not sure of their time, so it was naturally impossible for them to leave the body exposed at the scene.

"The photos and videos of the corpse have been sorted out. If you need to see them, you can retrieve them at any time." Wang Sheng followed behind and specifically told Jiang Yuan.

"Well, let's look at the traces of the explosion first." Jiang Yuan was not just using his skills. There were 11 deaths at the scene, and so many injured. If he wanted to check them all, 24 hours might not be enough, and he would lose the golden period for investigation.

In contrast, there is only one explosion, and obtaining explosives often has a threshold. Figuring out what the explosives are and understanding the circumstances of the explosion are often decisive in a bombing case.
