Chapter 415: Dou Dou Dingqiang

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

Jiang Yuan just smiled and picked it up, opened it, and was a bit surprised: "This is a case from Changyang City?"

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

Huang Qiangmin looked at Jiang Yuan at the end.

It's not strange that a local faction like Huang Qiangmin 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 case file was a blood-stained long nail. Below it was specially marked as a straight nail for a nail gun.

"A nail gun." Jiang Yuan immediately became energetic.

The management of firearms in China is becoming stricter and stricter, but the acquisition of nail guns is very easy. On the other hand, the power of nail guns is also quite large. Many nail guns can shoot through thin steel plates, and their power is greater than the small "smash guns" used by the police themselves. If they are modified, they have 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 jail because of such gun-related cases is in the triple digits, 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.

In such a luxury configuration, the case still became a cold case, so it won't be a simple case.

Jiang Yuan flipped through it from beginning to end and noticed a series of element collections.

Three old men climbing the mountain were shot to death on different mountain tops with nail guns pressed against their heads. There was no loss of personal property, the three old men had no connection, and the words "wilderness," "random crime" were marked clearly.

Plus gun involvement and continuous crime...

Jiang Yuan couldn't help but say: "This is a serial killer? How come there's no wind?"

"The case was originally said to be solved. The arrested person was a worker in an electronics factory, and a modified nail gun was also found in his home. During the interrogation, the third case occurred." Huang Qiangmin paused and said: "Director Yu called, also because this case is relatively complicated, hoping to solve the case before it ferments further."

Serial homicide cases in China are mostly violent crimes in the form of fleeing, similar to the nature of the "Two Wangs." Such serial killers who nest in one place and kill people, and don't deal with the corpses, are still rare.

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

If such a case is needed, it must be solved at all costs.

From Yu Wenshu calling Huang Qiangmin directly, he paid the price, and Jiang Yuan also belongs to the price.

"There are no clues or evidence." Jiang Yuan flipped through the copied version of the case 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 didn't need to say it so clearly.

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

"Then let's go and see."

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

Task: Dou Dou Dingqiang Murder Case.

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

This case, two rewards, there is nothing to say.

Jiang Yuan took the case file, pulled out all the photos, and looked at them carefully.

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

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

Yu Wenshu, for such a small matter, agreed to everything.

Three consecutive deaths, the arrested suspect, now it is not certain whether it was a wrong arrest or if there was a joint crime, and they couldn't be released immediately, so Yu Wenshu's pressure was also increasing.

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

"I negotiated with Old Huang. You should know the situation, right?" Yu Wenshu was exhausted, but his voice was stable. He had been arguing with his wife for years, and every time his emotions were unstable, he would be educated, so it was easy to become calm. Being able to sit firmly in the chair of the provincial capital's criminal police detachment, Mrs. Yu 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, but not many people should have gone. The third scene has been protected." 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 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 Qiangmin opposite, and smiled: "Director Huang is sometimes quite considerate."

"A bit of human touch. Not much." 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 a 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 would be benches for rest.

These benches, some facing the trail, some facing away from the trail, could be used to look at distant mountains and the city, designed very humanely.

The murderer borrowed this design, pressed a nail gun against the back of the head of an old man sitting on a long chair, facing the city and facing away from the trail, and shot him dead, then went down the mountain without looking back.

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

Jiang Yuan looked down at the 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 there are more people in the morning, and fewer people as it gets later.

And the footprints left on the ground are really too many, and it is 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 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 the 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.

"Are there no connections between the three victims?" Jiang Yuan asked an extra question.

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, nodded and said: "The official statement is that there is no connection."

"Unofficial?"

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

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

Jiang Yuan "hmm"ed to show he knew, and said: "If the murderer knows the true identity of the victim, then the steps are cumbersome, and he has to confirm it before shooting. It doesn't look like it, the target is an old man wearing a shirt, it is possible..."

Jiang Yuan gave an "Mm" to indicate he understood, and said: "If the killer knows the victim's true identity, then the steps would be cumbersome, and they would have to confirm it before firing. It doesn't really feel like it. The target being an elderly person in a shirt is also possible..."

And based on the information Jiang Yuan currently knows, judging the murderer's motive or target range, the information is insufficient. Letting 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 returned to the Criminal Police Detachment with Wan Baoming to check the only evidence, the long nail for the nail gun. ===== CHAPTER 416 =====

After surveying the scene carefully one more time, Jiang Yuan followed Wan Baoming back to the Criminal Police Detachment to examine the only piece of evidence: the long nails used in the nail gun.
