Chapter 709: Detailed Search of 5 Kilometers

Bureau Chief Chu jumped over the bushes by the road, crossed the excrement of the large upright ape, stood in front of the victim, carefully looked at the wounds on the corpse, and then stood up and sighed.

"Still a very young child. Are there any identity documents?" Bureau Chief Chu asked.

"There is an ID card in the backpack. 16 years old this year, from the capital, a high school freshman, studying in a key city school, no criminal record, parents are both high-level intellectuals, marriage is continuing..." Jiang Yuan had just checked the backpack. This was the fastest time he had determined the corpse source.

And the few points Jiang Yuan explained actually implied some exclusion points. For example, studying in a key city school and having no criminal record meant that a large amount of time had to be used for reading, and it was unlikely to come into contact with gambling and drugs, which were industries that easily involved gun crimes and forced people to take risks.

To use absolutely discriminatory words, those who go to business KTVs every day, if they want not to come into contact with gambling and drugs, it's difficult. If they are related practitioners, work hard for three years, and they are proper reserve forces of the underworld.

Bureau Chief Chu nodded and asked the most important question at this moment: "Was the deceased shot to death by a standard gun? Can the type of firearm be determined?"

"The bullet hasn't been found yet. The deceased's wound is a penetrating wound, the exit is star-shaped, typical characteristics of a rifled gun. Judging from the power, the possibility of a standard gun is high." Jiang Yuan pondered for a few seconds and said, "No smoke halo, no particle burns, it's a long-distance shot. Forensic long-distance shot, more than one meter."

"This case..." Bureau Chief Chu really had a big head, helplessly asked the lottery, "Can it be merged with the Zhang Lizhen case?"

"No." Jiang Yuan answered decisively, "At least there is no relevant point to see for the time being."

"Fine, that's one more gun-related case. What's your idea here, unified handling, or should I set up a special task force separately?" Bureau Chief Chu had less contact with Jiang Yuan and was worried that he didn't understand, so he specifically said, "If a special task force is set up separately, the crime area here will have to be given up to the newly established special task force. If they want to search or conduct a dragnet, you also have to discuss the issue of jurisdiction..."

If handled in a unified way, it is equivalent to being responsible for two cases at the same time, which of course is also very difficult. It is equivalent to choosing to shirk responsibility or choosing to take responsibility.

Jiang Yuan naturally chose the latter. He was a mercenary, and shirking responsibility was bound to lose.

Bureau Chief Chu was not surprised, nodded, and said, "Then I will report it upwards first. You guys hurry up and investigate."

The priority of gun-related cases is very high, but the number of gun-related cases is actually not as small as many people imagine, to the extent of reaching the sky. To give a chestnut, according to some public data, the Ministry announced that from May 20 to March 21, 24,000 gun and explosion cases were solved in various places, 113 gangs were destroyed, 314 dens were destroyed, and 24,000 criminal suspects were arrested. Another public news is that the Ministry deepened the special action to crack down on and rectify gun and explosion crimes. In the 24th round of centralized net-closing actions, 1,724 criminal suspects were arrested, 52 dens were destroyed, 3,975 various guns were seized, and 111,000 bullets were seized.

Just for the capital, in the first half of 19 years, the city solved 18 gun-related cases, seized more than 170 various illegal guns, more than 650 simulated guns, more than 33,000 bullets, and more than 30 waste shells (landmines), and administratively detained more than 140 people and criminally detained more than 30 people.

A very reasonable inference is that if gun-related cases were really rare to the extent that one would go out of the circle, then there would be no need to hold special actions for various types of gun-related crimes.

Tao Lu and others also looked at the scene one after another, and Jiang Yuan continued to do the crime scene investigation.

Cui Qishan, who followed the footsteps of the leaders, shook his head helplessly at the members of his special task force and asked Tao Lu, "Detachment Leader Tao, I don't know if Team Leader Jiang is good at gun-related cases. Do you want to find a firearms expert to come over?"

This could also be considered a very normal suggestion. Ordinary police officers rarely come into contact with gun-related cases.

After all, in the capital, three or fifty gun-related cases a year, the number of shooting cases is even smaller, and the frequency of appearance is actually the same as the abnormal death in a small county. A small county only needs one forensic doctor to deal with these abnormal deaths. Similarly, the Capital Bureau actually only needs one person to deal with these gun-related cases.

Tao Lu hesitated for a moment, turned to ask Huang Qiangmin.

Huang Qiangmin said casually, "Since Team Leader Jiang didn't call for reinforcements, it should be unnecessary for now. Of course, it's not impossible to find someone to come over and take a look..."

If it were up to Huang Qiangmin to decide, Huang Qiangmin would definitely listen to Jiang Yuan in terms of technology. But from another angle, Huang Qiangmin was worried about letting Jiang Yuan take too much responsibility, so he felt it was good to find an expert to come over and take a look.

Tao Lu nodded and watched Jiang Yuan operate. Although there was a sense of urgency, it wasn't urgent to the point of not being able to wait for a moment.

Jiang Yuan was dealing with various evidence step by step.

In dealing with gun-related cases, the first step should be to find bullets, shell casings, and firearms. These three are in direct physical contact with the murderer and are very easy to obtain relevant information. Most gun-related cases are solved based on this.

When luck is good, the murderer will throw the firearm at the scene, the shell casing will fall beside the gun, and the bullet will remain in the deceased's body. This is something that only happens when everything hits good luck—the deceased might not think so, but he can no longer express his opinion.

As for this case, Jiang Yuan couldn't see the firearm at the scene, so he just sent people to search around. By the way, he also tried to find the first scene and possible shell casings.

Judging from the traces at the crime scene, after the deceased was hit, he should not have realized what happened at the time, subconsciously walked forward, but soon had physical exhaustion, and even lost consciousness. So, he took the backpack off his back, carried it in front of his chest, sat down on the spot, took out the water bottle to drink water, and then died of excessive blood loss and shock.

This process should be relatively fast. Referring to the bleeding time of the pig-killing scene, the ability of humans to struggle and move, no matter how strong, is not much better. As for specific data, it is estimated that there is no experimental data.

More than a dozen crime scene investigators and police officers went around in circles to find guns and bullets.

In theory, the scene can follow the bloodstains, but in reality, in the woods this season, humans can't distinguish bloodstains well. Furthermore, considering the position of the firearm and the shell casing, they are easily affected by the murderer, so forcing a search for blood is meaningless. At the same time, the bullet may have penetrated the victim's body, and it is difficult to say where it fell.

Jiang Yuan focused his main energy on the shooting traces.

Shooting traces are divided into two categories. One is the intrusion traces of the bullet, that is, the impact point, as well as the entrance and exit, and the trajectory. For example, the star-shaped exit that Jiang Yuan just emphasized can provide information such as the type of firearm, and the trajectory has a great possibility of providing the positional relationship between the two sides during the conflict.

However, because of the victim's movement at the last moment, it is not very convenient to determine the trajectory through the shooting tube in his body.

Jiang Yuan only took a rough look and delayed this part of the work, waiting for others to finish the investigation and then combine the information from all sides.

Then, Jiang Yuan began to deal with the second category of shooting traces, which is shooting residues. This part includes traces left on clothes, as well as wiping wheels and contusion wheels.

This is a concept that ordinary people in China rarely come into contact with. It is the dirty things attached to the bullet when the bullet rotates into the skin, such as metal shavings, grease, snot, mud, etc., scraping a circle of black-brown wheel-shaped bands on the edge of the window skin, with a width of about 1 millimeter, generally ring-shaped, and extremely obvious after drying.

If there is a sufficient database, just the information on the wiping wheel may solve the case.

Jiang Yuan studied it with great interest, while Liu Jinghui finished his observation and jumped off the tree.

Liu Jinghui thought for a moment, then pulled Xu Taining and asked, "Division Chief Xu, is the investigation in this area detailed? To what extent can it be detailed?"

"Average level." Xu Taining said.

The average level is a few people per square kilometer. Because drone teams are composed of multiple people, on average, there are only single-digit police officers per square kilometer.

Liu Jinghui nodded and said, "Can we strictly search the surrounding area with this place as the center?"

"What range?"

"Walkable, a radius of 5 kilometers? At least 3 kilometers."

Xu Taining calculated, and the area was not small, so he said, "A detailed search of 3 kilometers should be no problem."

"I mainly consider that the deceased didn't walk far after being hit, and the items around him were complete, indicating that the murderer's purpose was not for money. Secondly, the deceased was a teenager, and the possibility of provoking the god of death was not high, at least it shouldn't be like this, being shot to death. Therefore, the murderer's purpose doesn't look like plotting against people. The possibility of an accident is very high." Liu Jinghui explained in a low voice.

"You said earlier, hunting accident?"

"It's very possible, maybe it was even a stray bullet, and the murderer didn't find it. Of course, the probability of this is still relatively low. But regardless, the murderer is either a licensed hunter or an illegal one. For the licensed one, I'll let Wang Chuanxing and the others check. If it's illegal, maybe it's the same batch of people as the Zhang Lizhen case!" Liu Jinghui's reasoning was seamless, making Xu Taining's expression serious.

"Fine. Then let's do a detailed search of 5 kilometers." Xu Taining ordered quickly. ===== CHAPTER 710 =====
