Chapter 415: Nail Gun

The case pushed out by Huang Huang Qiangmin was not thick among the files, just at the middle-upper level.

Jiang Yuan just smiled, took it over, opened it, and was a little surprised: "This is a case from Changyang City?"

"Oh... you just happened to take a case from Changyang." Huang Huang Qiangmin said: "Then see if it's suitable. It's a coincidence. The cases from other counties aren't that urgent, and it's not that we don't care about brotherhood. Changyang City is the provincial capital, and its help to us is great. Although Director Chai is quite willing to help brother counties and districts..."

Huang Huang Qiangmin looked at Jiang Yuan at the end.

It's not strange that Huang Huang Qiangmin, a local faction, can't pee in the same pot as Director Chai. As for Jiang Yuan, his Ningtai County identity is also not easy to change.

"If it's Changyang City, it's Director Yu's case..." Jiang Yuan said while opening it to look, and saw the first photo in the file, which was a blood-stained long nail. Below it was specially marked that it was a straight nail used by a nail gun.

"Nail gun." Jiang Yuan immediately became energetic.

Domestic firearm management is becoming stricter and stricter, but nail guns are very easy to obtain. On the other hand, the power of nail guns is not small. Many nail guns can shoot through thin steel plates, which is more powerful than the small guns used by the police. If you modify it, it has both power and convenience.

Jiang Yuan had seen reports about this before. Modified nail guns, after adding steel pipes and sights, can shoot birds, hunt, and naturally can shoot people. In recent years, the number of people who have gone to prison because of such gun-related cases is in the hundreds, and the sentencing is not light.

For such cases, the police attach great importance to them. The degree of importance is even above ordinary eight-category cases. In the consumer field, it can be understood as a luxury configuration.

Then, a case that has become a cold case under a luxury configuration is definitely not a simple case.

A case that still becomes a cold case despite such luxurious resources will not be a simple one.

Three old men climbing the mountain were shot dead by nail guns on different hills. There was no loss of personal belongings, and the three old men had no connection. The words "wilderness" and "random crime" were clearly marked.

Plus gun-related and serial crimes...

Jiang Yuan couldn't help but say: "This is a serial killer? How come no news has spread?"

"The case was originally said to be solved. The one arrested was a worker in an electronics factory, and a modified nail gun was also found in his home. While he was being interrogated, the third case occurred." Huang Huang Qiangmin paused and said: "Director Yu called, also because this case is relatively complex, and he hopes to solve the case before it further ferments."

Domestic serial homicide cases are mostly violent crimes in the form of wandering, similar to the nature of the "Two Kings." It is rare to see such a serial killer who nests in one place and kills people without dealing with the corpses.

Of course, for the police, the provocation is also very strong.

If there is a need for such a case, it must be solved at all costs.

From the fact that Yu Yu Wenshu called Huang Huang Qiangmin directly, he paid a price, and Jiang Yuan also belongs to the price.

"There are no clues or evidence." Jiang Yuan flipped through the photocopy of the file and said: "To solve this case, we can only look at the situation at the scene and the situation of the corpse."

It might also be necessary to wait for the fourth case to occur before it can be solved. Jiang Yuan doesn't need to be that clear.

Huang Huang Qiangmin "hmm" and said: "Director Yu is still quite urgent. If you have confidence, you can still go and do it."

"Then go and see."

As soon as Jiang Yuan finished speaking, the system's voice came to his mind:

Task: Nail Gun Murder Case.

Task content: The death of 3 consecutive victims made Yu Yu Wenshu anxious. In order to solve this case, he can do anything. Seize the opportunity!

This case, two rewards, nothing to say.

Jiang Yuan took the file, took out the photos, and checked them carefully.

Huang Huang Qiangmin got Jiang Yuan's promise and immediately called Yu Yu Wenshu again to start arranging the trip to Changyang City.

Jiang Yuan's cold case task force has so many people, so going to Changyang City on business naturally needs to be arranged properly. As for Wang Wang Chuanxing and others who are mostly from the Changyang City Criminal Police Detachment, that is another matter.

Yu Yu Wenshu promised everything for such trivial matters.

Three people died in succession, and the arrested suspect is not sure whether it was a wrong arrest or if there was a conspiracy. He cannot be released immediately, which increases Yu Yu Wenshu's pressure.

After chatting with Huang Huang Qiangmin, Yu Yu Wenshu specifically called Jiang Yuan.

"I have negotiated with Old Huang. You should know the situation, right?" Yu Yu Wenshu was exhausted, but his voice was stable. He had been educated every time his emotions were unstable when arguing with his wife over the years, so it was easy for him to become indifferent to favor or humiliation. Being able to sit firmly in the chair of the provincial capital's criminal police detachment under great pressure, Yu's wife had a share of the credit.

Jiang Yuan responded and asked: "Is the scene still there?"

"The first and second scenes have been released. They are both rest areas in scenic spots, so no warning tape was pulled again. However, there shouldn't be many people going there. The third scene has been protected." Yu Yu Wenshu said with some expectation, asking: "When can you arrive?"

"If you are in a hurry, I will go over now." Jiang Yuan said.

"In a hurry. If it weren't in a hurry, I wouldn't have promised your Director Huang a laboratory." Yu Yu Wenshu hummed and said: "Looking at the fact that he said it was prepared for you, I agreed."

He was selling one thing for two.

Jiang Yuan accepted it, looked at Huang Huang Qiangmin opposite, and smiled: "Director Huang is sometimes quite considerate of others."

"A little human touch. Not much." Yu Yu Wenshu gave an objective evaluation.

Four hours later, Jiang Yuan arrived in Changyang City.

Jiang Yuan's cold case task force followed, looking at this city from different directions, and then...

Everyone was pulled to Yuanbei Mountain in the suburbs.

The scene of the third case was at a rest area on the trail halfway up the mountain.

The trail was very wide, paved with red bricks, winding along, quite beautiful. Every distance, there would be a larger platform, and there were long chairs for rest.

These long chairs, some facing the trail, some with their backs to the trail, were for viewing distant mountains and the city, designed very humanely.

The murderer borrowed this design and shot an old man who was sitting on a long chair, facing the city and with his back to the trail, to death with a nail gun.

Jiang Yuan stood at the trail, and without needing skills like bloodstain analysis, he could easily see that the murderer just walked up or down the trail, saw the lone old man with his back to him, took out the nail gun, approached the long chair, shot a nail into the old man's back of the head, and went down the mountain without looking back.

Jiang Yuan looked down at his surroundings again.

This place is more than twenty minutes' walk from the starting section of the trail, and it is about the same time from the top of the mountain.

On weekdays, there are quite a few people coming to the trail for leisure or exercise, but it is common to see no one for several minutes, and it is crowded in the morning, and fewer people as it gets later.

And the footprints left on the ground were too many, and it was impossible to judge which ones might be the murderer's.

Jiang Yuan specially went behind the long chair to look, and there were no usable footprints on the red brick floor.

"It really is a random crime." Jiang Yuan waved his hand, asked for photos from Mu Mu Zhiyang's bag to look at, and it was easy to see that the victim's head and neck were in a very natural drooping posture, meaning the murderer didn't even call him, and pulled the trigger directly at the back of his head.

Police officers have to ask "what is your name" to determine the suspect's identity when arresting people, and judging from the murderer's posture of killing, he really didn't care who he killed.

"Do the three victims have no connection?" Jiang Yuan asked an extra question.

Wan Wan Baoming, the deputy director of the Criminal Science Center who came to pick up the car and entertain, was very familiar with Jiang Yuan and nodded: "The official statement is that there is no connection."

"Unofficial?"

"I don't know if it counts, but the three victims are all retired veteran cadres, sixty or seventy years old. From the appearance, when the three of them died, they were all wearing shirts and trousers. Outer jackets or vests." Wan Wan Baoming paused and added: "This analysis is a private analysis, not certain."

If it is determined to be a serial murder case targeting retired veteran cadres, then the pressure from above will be even tighter, and it may cause very bad public opinion.

Jiang Yuan "hmm" to show he knew, and added: "If the murderer knows the true identity of the victim, the steps will be cumbersome, and he has to confirm it before shooting. It doesn't look like it. The target is elderly people wearing shirts, which is possible..."

He didn't dwell on this topic for too long. From the scene, this is a typical random crime, neither seeking money nor sex, more like killing for the sake of killing, which is anti-social behavior. It happens that this kind of case is the most difficult to solve, so unless it is a last resort, the police are unwilling to admit that such a case is ongoing.

And based on the information Jiang Yuan currently knows, judging the murderer's motive or target range, the information is insufficient. Letting Liu Liu Jinghui do this case, he might guess one, or use so-called profiling to guess an answer, but Jiang Yuan won't do that.

After carefully investigating the scene again, Jiang Yuan followed Wan Wan Baoming back to the Criminal Police Detachment to check the only evidence, the long nail used by the nail gun. ===== CHAPTER 416 =====

After surveying the scene again with meticulous care, Jiang Yuan returned to the Criminal Police Detachment with Wan Wan Baoming to examine the only piece of evidence: the long nails used in the nail gun.
