Chapter 1068 Internal and external investigation
If someone else was so insistent, Cao Chujun would have to retort. But since it was Jiang Yuan who insisted, Cao Chujun had to pay more attention.
"I have checked all the files that can be found in the country, and there is no such person. In addition, I have also asked a few connections, but there has been no reply so far, and there should be none." Yu Wenshu was pulled up by Cao Chujun. After walking around for a while, he turned around and met Jiang Yuan again.
Jiang Yuan rubbed the statue of Guan Gong on his chest, nodded slightly, and said: "Don't worry, let's continue the investigation. There is no second suspect yet. This Lu Jianchun is still very suspicious."
"The suspect Lu Jianchun does have some problems. Ordinary people are definitely not like this when facing interrogations. Even if he is not the murderer of this case, he is probably carrying other cases." Cao Chujun, a veteran criminal policeman, Still very aware of this. When he was young, solving a series of cases mainly relied on interrogation. Unlike now, when he gets the suspect's mobile phone and checks it, all the deleted information comes out.
Several people nodded in unison. This is also the main reason why everyone's mood has remained relatively stable since the two days of interrogation.
If you really meet an ordinary person who knows everything and talks about everything, and is afraid of innocent people, this case will be troublesome.
Although Lu Jianchun had a relationship with victim No. 1 Zhao Qian, it was not illegal. Furthermore, Zhao Qian had many targets, and Lu Jianchun's condition was considered to be the most beautiful one among Zhao Qian's targets. , it is normal for it to be taken down within its radiation range.
"Lu Jianchun's ex-wife and relatives, as well as Lu Jianchun's friends, can also step up visits. If necessary, bring them back to the bureau for questioning." Liu Jinghui proposed a simple solution.
Yu Wenshu immediately said: "That's okay, no problem."
The suspect is difficult to defeat, so start defeating him from 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 for people. It is difficult for a completely lonely person to survive in the world.
Even if Lu Jianchun keeps secret, his life cannot be completely confidential - if that is the case, the problem will be even greater.
Several people left the conference room and started busy themselves.
Jiang Yuan told Yu Wenshu and returned to the small house he bought behind the criminal police detachment.
This 220-square-meter, warmly decorated small house suddenly seemed even smaller after more than a dozen people were crammed into it.
Fortunately, they were all working as criminal police officers. They had had fun and entertainment, and had stayed in 80-yuan youth hostels. Most of them were not so picky. A few of them with wives even took the initiative to shoulder the responsibilities of housework and boiled hot water for everyone.
Jiang Yuan ordered a few pots of Haidilao, and after waiting for them to be delivered, he invited everyone to eat together.
Because the case was at a critical stage, a group of people didn't shout about drinking or anything like that. They were just eating pots of meat.
The warm hot pot, the close comradeship, and the joy of having experienced danger and even bullets together made the atmosphere at the scene very warm.
Liu Wenkai picked up the Coke and raised his glass to drink: "It's really comfortable to follow Team Jiang on the case. There is a car to take me back and forth. The detachment leader from the provincial capital city came out in person to solve the case while eating hot pot and singing songs."
Jiang Yuan was modest; "This case has not been solved yet."
"Sooner or later. Moreover, in my opinion, there may be something in this case. There is a bit of a problem with the identity of Lu Jianchun." Liu Wenkai smiled but there was absolutely nothing wrong with his vision.
"Don't be a spy again." Mu Zhiyang followed Jiang Yuan all over the country, and his vision was very high. He had also fought spies and other things. He has also seen the guns of spies.
Some young detectives looked at each other, secretly feeling a little excited. It is difficult for ordinary people to see spy cases, and it is equally difficult for criminal police, and everyone's curiosity is about the same.
Jiang Yuan recalled the circumstances of the case, but smiled and said: "It is unlikely that he is a spy. At least, Lu Jianchun does not look like a spy. He has good physical fitness, but low education. In terms of personality, he feels Also quite stubborn.”
"Without a stubborn character, you wouldn't be able to practice Kung Fu like him." Meng Chengbiao rinsed two plates of tripe silently, counting in his mind, and said: "I read their interrogation records, this Lu Jian Chun is somewhat of a charlatan, even if he is recruited by some spy network, he can only be the most fringe character. "
A group of people then started chatting about this high-end topic.
Jiang Yuan dipped the garlic sesame oil in his mouth and ate a large plate of meat. He wiped his mouth, looked at Liu Jinghui next to him, and said, "This Lu Jianchun looks like a relatively earthy traditional man, right?"
Tang Jia said from the side: "He hooked up with me."
Liu Wenkai: "Hooking up is a traditional man."
Tang Jia's CPU was overloaded crazily. Liu Jinghui nodded and said, "What do you have in mind?"
"I looked at the timetable they pulled out of the interrogation records. Lu Jianchun has been working locally since graduation and rarely spent time outside the province. From this point of view, if he has done other cases, will they all be in the province? Made locally?”
When Jiang Yuan said this, Liu Jinghui immediately understood.
Liu Jinghui couldn't help but nodded and said: "Check the local cases of 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, they are basically the same person, right? ”
Jiang Yuan had used similar methods before, but it was just a matter of scope.
Criminal policemen actually like to use old methods, or in other words, everyone likes to use mature solutions to solve cases. In the medical category, this is called mature solutions, expert consensus, and treatment guidelines.
For people on the job, it doesn't matter whether the method is new or not, as long as it is easy to use.
Jiang Yuan immediately turned around and said, "Chuanxing, I'll leave it to you. Tomorrow, sort out similar cases in Shannan Province. The key is to have photos of bloodstains at the scene. The more complete the better."
"Yes." Wang Chuanxing agreed, and then quickly poured two plates of meat into the pot. At night, I was about to stay up late, so I had to eat more to get through it.
Liu Jinghui looked at Wang Chuanxing sympathetically. Just to make the PPT, Wang Chuanxing didn't know how many nights he had stayed up, but there was no way. Jiang Yuan's backlog special team was also very competitive, and it was even more difficult 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 former teammates in the criminal police detachment.
"If Chuanxing sorts out the information by himself, the workload may 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 the hot pot.
Some people were happy, some laughed, and some did homework.
Jiang Yuan returned to the master bedroom, checked his phone for a while and fell asleep.
The next morning, members of Jiang Yuan's backlog team began to cooperate with Wang Chuanxing and Shen Yaowei, who had not slept all night, to find information.
At noon, Yu Wenshu called: "Lu Jianchun has a childhood friend who provided very important information."
