Chapter 1051

If someone else insisted like this, Cao Chujun would have had to refute a couple of sentences. But since it was Jiang Yuan who insisted, Cao Chujun had to pay more attention.

"I have checked all the files that can be checked domestically, and there is no such person. In addition, I also found a few relationships to ask, and there has been no reply so far, so there should be none." Yu Wenshu was pulled around by Cao Chujun, turned his head, and met Jiang Yuan again.

Jiang Yuan rubbed the Guan Gong statue on his chest, nodded slightly, and said: "No rush, continue to investigate. Temporarily, no second suspect has appeared. This Lu Jianchun is still very suspicious."

"This suspect Lu Jianchun does have some problems. Faced with interrogation, ordinary people certainly wouldn't be like this. Even if he isn't the killer of this case, he probably has other cases on his back." Cao Chujun, an old criminal policeman, understood this very well. When he was young, his series of cases were mainly solved by interrogation, unlike now, where you check the suspect's mobile phone and deleted information pops out.

Several people nodded in unison. This was also the main reason why everyone's mood was relatively stable during the two days of interrogation.

If they had really encountered an innocent ordinary person who knew everything and was terrified, this case would have been troublesome.

Although Lu Jianchun had a relationship with Victim No. 1 Zhao Qian, this thing is not illegal. Furthermore, Zhao Qian's targets were many, and Lu Jianchun's conditions were among the top in Zhao Qian's targets. Being taken down within her radiation range was normal.

"Lu Jianchun's ex-wife and relatives, as well as Lu Jianchun's friends, can also be strengthened in visits. If necessary, bring them to the bureau to ask." Liu Jinghui proposed a simple method.

Yu Wenshu said immediately: "This is fine, no problem."

If the suspect is difficult to break, start breaking from the people around him. There is no such thing as a truly lonely person in the world, because a person is the sum of all relationships. Establishing interpersonal relationships is the most basic need of a person, and a completely lonely person is very difficult to survive in the world.

Even if Lu Jianchun kept his mouth shut, his life couldn't be completely secret—if this were really the case, the problem would be even bigger.

Several people left the conference room, each busy.

Jiang Yuan told Yu Wenshu and returned to his small house bought behind the criminal investigation detachment.

This 220-square-meter, warmly decorated small house was stuffed with a dozen or so people at once, suddenly appearing even smaller.

Fortunately, they were all criminal police. They had experienced the glitz and glamour, and had lived in 80-yuan youth hostels, so most of them weren't that picky. Several who had wives even took the initiative to take on housework responsibilities and boiled hot water for everyone to drink.

Jiang Yuan ordered a few pots of Haidilao. When people sent them over, he greeted everyone to eat together.

Because the case was at a critical juncture, a group of people didn't shout about drinking or anything, just putting meat into the pots one after another.

The hot hotpot, the intimate comradeship, and the luck of having experienced danger and even bullets together made the atmosphere at the scene very warm.

Liu Wenkai picked up the cola, raised his glass and drank: "It's really comfortable to handle cases with Team Leader Jiang. There are cars to pick up and drop off, the detachment leader of the provincial capital city comes out in person, and the case is solved while eating hotpot and singing."

Jiang Yuan was modest: "The case this time hasn't been solved yet."

"It's a matter of time. And, in my opinion, this case might still have something in it. The identity of this Lu Jianchun has some problems." Liu Wenkai laughed, but his vision was absolutely no problem.

"Don't be a spy again." Mu Zhiyang followed Jiang Yuan north and south, and his vision was already very high. He had also fought spies and such. He had also seen the bullets of spies.

Some young criminal police looked at each other, secretly carrying a bit of excitement. It is very difficult for ordinary people to see spy cases, and it is also very difficult for criminal police, and everyone's curiosity is about the same.

Jiang Yuan recalled the situation of the case, but smiled and said: "The possibility of being a spy is not great. At the very least, Lu Jianchun doesn't look like a spy. He has good physical fitness, but a low level of education. In terms of personality, he also feels relatively stubborn."

"Without a stubborn personality, you can't practice his kind of kung fu." Meng Chengbiao silently swished two plates of tripe, counted seven up and eight down in his heart, and said: "I read their interrogation records. This Lu Jianchun has a bit of that kind of 'jianghu' spirit. Even if he was recruited by some spy network, he could only be the most marginal role."

A group of people started chatting about this high-end topic.

Jiang Yuan dipped in garlic and sesame oil, ate a large plate of meat, wiped his mouth, looked at Liu Jinghui next to him, and said: "This Lu Jianchun, feeling-wise, is actually that kind of relatively earthy traditional man, right?"

Tang Jia said on the side: "He's a hookup."

Liu Wenkai: "Hooking up is a traditional man."

Tang Jia's CPU was frantically overloading. Liu Jinghui nodded and said: "Do you have any thoughts?"

"I looked at the schedule pulled out from their interrogation records. Lu Jianchun has worked locally since graduation, and the time he has been out of the province is very little. Looking at it this way, if he had done other cases, would they also have been done locally?"

As soon as Jiang Yuan said this, Liu Jinghui immediately understood.

Liu Jinghui couldn't help nodding and said: "Check the cases that appeared locally in the past few years using long knives. If there are photos of the scene, you should be able to connect them, right? If the height and arm span are the same, it's basically the same person, right?"

Jiang Yuan had used similar methods before, it was just a matter of the size of the scope.

Criminal police actually like to use old methods, or rather, everyone likes to use mature plans to do cases. In the medical category, this is called a mature plan, expert consensus, and treatment guidelines.

For people in the post, it doesn't matter if the method is new or not, as long as it is easy to use.

Jiang Yuan immediately turned his head and said: "Chuanxing, I'll leave it to you. Organize similar cases in Shannan Province tomorrow. The key is to have photos of the bloodstains at the scene, as complete as possible."

"Yes." Wang Chuanxing responded, then quickly poured two plates of meat into the pot. Seeing that he was going to stay up late at night, he had to eat at least a little more to carry it through.

Liu Jinghui looked at Wang Chuanxing with sympathy. Just to make the PPT, Wang Chuanxing didn't know how many big nights he had stayed up, but there was no way. Jiang Yuan's cold case team was also very competitive internally, and it was even harder to get ahead. Not to mention doing things in the original units of these borrowed officers, everyone was trying their best to make the former and later teammates of the criminal investigation detachment look at them with admiration.

"If Chuanxing organizes the materials alone, the workload might be a bit large." Liu Jinghui released his sympathy.

Jiang Yuan expressed agreement, looked left and right, and said: "Let Yaowei help Chuanxing."

"Ah... yes!" Shen Yaowei slowly put down his chopsticks.

After hotpot.

Some were happy, some were holding their bellies, and some were doing homework.

Jiang Yuan returned to the master bedroom, swiped his phone for a while, and went to sleep.

Early the next morning, the members of Jiang Yuan's cold case team began to cooperate with Wang Chuanxing and Shen Yaowei, who hadn't slept all night, to find materials.

By noon, Yu Wenshu's phone call came: "Lu Jianchun has a childhood friend who provided very important information."
