Chapter 1068 Internal and External Investigation

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

"I have checked all the files available in the country, and there is no such person. In addition, I also asked a few contacts, but there has been no reply so far, so there should be no such person." Yu Wenshu was taken for a walk by Cao Chujun, and then turned around and met Jiang Yuan again.

Jiang Yuan stroked the Guan Gong statue on his chest, nodded slightly, and said, "Don't be anxious, continue investigating. No second suspect has appeared yet, and this Lu Jianchun is still very suspicious."

"Lu Jianchun is indeed a bit problematic. Most people would not be like this when facing interrogation. Even if he is not the murderer in this case, he is probably involved in other cases." Cao Chujun, an old criminal policeman, is very familiar with this. When he was young, he mainly relied on interrogation to solve serial cases. It is not like now. If you check the suspect's mobile phone, all the deleted information will be revealed.

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

If we really encounter an ordinary person who knows everything and is afraid of innocent people, the case will be troublesome.

Although Lu Jianchun had had sex with victim number one, Zhao Qian, this was not illegal. Moreover, Zhao Qian had many targets, and Lu Jianchun was considered to be of good looks among Zhao Qian's targets. It was normal for him to be captured within her range.

"We can also visit Lu Jianchun's ex-wife and relatives, as well as Lu Jianchun's friends, more frequently. If necessary, bring them back to the bureau for questioning." Liu Jinghui proposed a simple solution.

Yu Wenshu immediately said: "That's fine, no problem."

If the suspect is hard to crack, then start by cracking the people around him. There is no truly lonely person in the world, because people are the sum of all relationships, and establishing interpersonal relationships is the most basic need of people. It is difficult for a completely lonely person to survive in the world.

Even if Lu Jianchun kept his mouth shut, his life could not be completely secret - if that were the case, the problem would be even bigger.

Several people left the meeting room and started to work on their own.

Jiang Yuan said something to Yu Wenshu and went back to the small house he had bought behind the Criminal Police Brigade.

This 220-square-meter, warmly decorated little house suddenly seemed even smaller with more than a dozen people crammed into it.

Fortunately, they are all criminal police officers. They have experienced the bright lights and wine, and stayed in 80-yuan youth hostels. Most of them are not that picky. Some of them who have wives even took the initiative to take on the housework responsibilities and boiled hot water for everyone.

Jiang Yuan ordered a few pots of Haidilao, and when the food was served, he invited everyone to eat together.

Because the case was at a critical juncture, no one was shouting about drinking or anything like that, they just ate pots of meat.

The hot pot, the close comradeship, and the gratitude for having experienced danger and even bullets together made the atmosphere very warm.

Liu Wenkai picked up the Coke and drank. "It was really comfortable to work with Captain Jiang. There was a car to pick us up and drop us off. The captain of the provincial capital city came in person. We solved the case while eating hot pot and singing songs."

Jiang Yuan said modestly, "This case has not been solved yet."

"It's only a matter of time. Besides, in my opinion, there might be something else behind this case. There are some issues with Lu Jianchun's identity." Although Liu Wenkai was laughing, his vision was absolutely flawless.

"Don't tell me it's another spy." Mu Zhiyang had traveled extensively with Jiang Yuan, and his standards were already very high. He had seen spies before, and he had seen the bullets fired by spies before.

Some young detectives looked at each other, secretly a little excited. It was difficult for ordinary people to see a spy case, and it was also difficult for detectives, but everyone's curiosity was similar.

Jiang Yuan thought about the case and smiled, saying, "It's unlikely that he's a spy. At least, Lu Jianchun doesn't look like a spy. He has good physical fitness, but low education, and he seems to be quite stubborn in character."

"Without a stubborn character, you can't develop such kung fu." Meng Chengbiao silently ate two plates of tripe, counting his pulse in his heart, and said, "I read their interrogation records. This Lu Jianchun has some gangster spirit. Even if he was recruited by some spy network, he can only be a marginal character."

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

Jiang Yuan ate a large plate of meat with garlic and sesame oil, wiped his mouth, looked at Liu Jinghui next to him, and said, "This Lu Jianchun seems to be a traditional man who is a bit rustic, right?"

Tang Jia said beside him: "He's here for one-night stands."

Liu Wenkai: "Hooking up for sex is what traditional men do."

As Tang Jia's CPU was overloaded, Liu Jinghui nodded and said, "What do you think?"

"I looked at the timeline in their interrogation records. After Lu Jianchun graduated, he worked locally and rarely left the province. So if he had committed other crimes, would they have been committed locally?"

After Jiang Yuan said this, Liu Jinghui immediately understood.

Liu Jinghui couldn't help but nod and said, "Look up local cases involving long knives in the past few years. If there are photos of the scene, you should be able to connect them. If the height and arm span are the same, it's basically the same person."

Jiang Yuan had used a similar method before, the only difference was the size of the scope.

Criminal policemen actually like to use old methods, or in other words, they all like to use mature plans to solve cases. In the medical category, this is called a mature plan, expert consensus, and treatment guidelines.

For people in their positions, it doesn’t matter whether the method is new or not, as long as it works.

Jiang Yuan immediately turned around and said, "Chuan Xing, I leave it to you. Tomorrow, sort out similar cases in Shannan Province. The most important thing is to have photos of the bloodstains at the scene. The more complete the better."

"Yes." Wang Chuanxing agreed, and 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 a little more to get through it.

Liu Jinghui looked at Wang Chuanxing sympathetically. Wang Chuanxing didn't know how many late nights he had stayed up just to make the PPT. But there was nothing he could do. The Jiangyuan backlog case team was also very competitive, and it was not easy to get ahead. Not to mention working in the original units of these seconded police officers, everyone was working hard to impress their former and current teammates in the Criminal Police Detachment.

"If Chuanxing organizes the information alone, the workload might be a bit too much." Liu Jinghui released his sympathy.

Jiang Yuan agreed, looked around, and said, "Yaowei, help Chuanxing."

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

After hot pot.

Some are happy, some are laughing, and some are doing homework.

Jiang Yuan returned to the master bedroom, checked his phone for a while, and then fell asleep.

Early the next morning, members of Jiang Yuan's backlog case task force began to work with Wang Chuanxing and Shen Yaowei, who had not slept all night, to search for information.

At noon, Yu Wenshu called and said, "Lu Jianchun has a childhood friend who provided very important information."
