The case analysis meeting on Lu Xiaoyuan's case was held in the conference room of the Criminal Police Brigade that night. Although Lu Xiaoyuan is a citizen of the Dragon Kingdom. But he is also the top cybersecurity talent in Dragon Country, and he is also the CEO of a well-known network security company in Dragon Country, so this seemingly ordinary kidnapping case is destined not to be an ordinary blackmail kidnapping case.

"Officer Liu, tell me about the results of the investigation."

"Okay. Through our investigation, it was found that the internal and external doorknobs of the room did not have fingerprints, and it was judged that they were wiped and processed. There were no footprints in the room and no mops were found in the room. It was judged that someone had used a mop to clean the footprints in the room, and after cleaning, the mop was also taken away. The hard disk of the desktop computer in the room was removed, and the laptop was not in the room, we had already called their company, and Lu Xiaoyuan's laptop was not in the company. There are several cigarette butts in the ashtray in Lu Xiaoyuan's bedroom, and there is a leftover bucket of instant noodles in the garbage building. Through our laboratory test of instant noodles, it can be concluded that they were leftovers on the night of July 11. ”

"Could it be that Lu Xiaoyuan cleaned the room by himself, after cleaning, he didn't go back to the room." Zhaohui, who participated in the case analysis meeting, asked.

"This may be almost none. There are several reasons for this. First, we found that Lu Xiaoyuan had a 6-minute call at 8:17 p.m. on July 11 at the base station of the community. Assuming he only went downstairs and didn't come home, where did the leftover instant noodles come from? So he should be at home making phone calls and eating instant noodles. The second question is why he took the mop away after mopping the ground. Third, why did he leave to wipe down the inside and outside of the doorknob? Fourth, why did he remove the hard drive from his computer desktop? From the analysis of the above four suspicious points, Lu Xiaoyuan should have been kidnapped at home, and when the kidnappers left, the traces were removed. ”

"In addition to the loss of the mop in the room, are there any other belongings missing?"

"No, a watch and a lot of cash in his drawer were not missing. Kidnapping for property is extremely unlikely. ”

"Judging from the lost hard drive, the kidnappers should have come to land Xiaoyuan's research results."

"There is also a problem, since there are no signs of prying on the door. How did the kidnappers get into Lu Xiaoyuan's room? ”

"There may be two possibilities in this, first, it is someone Lu Xiaoyuan knows. Second, it is the person Lu Xiaoyuan must open the door to meet. ”

The conclusions of the case analysis all point to the fact that the kidnappers came from the research results of Lu Xiaoyuan. The direction of the case is to investigate why Lu Xiaoyuan opened the door to the kidnapper.

"Xiao Liu, you take the first group to investigate Lu Xiaoyuan's social relations and find out the suspect."

"Sima, you take the second group to investigate the personnel of Lu Xiaoyuan's company and rival companies and find out the suspects."

"Lina, you go to Lu Xiaoyuan's community again, and find out the situation of people entering and leaving the community around July 11."

"Yes." In accordance with the orders of Brigade Commander Wen, each team quickly carried out the investigation of the case. This case is also known as the "711" kidnapping case.

The personnel of the criminal police team have been working intensively for three consecutive days, and there has been no progress in any clue.

The first group of information reported by the investigation, Lu Xiaoyuan's social relations have evidence of his alibi on the night of July 11.

The second group of information from the investigation and feedback, Lu Xiaoyuan's company and the relevant personnel of the competitor company have evidence of alibi on the evening of July 11.

The third group of investigations, through the investigation of community security and residents, a few days before and after July 11, no suspicious people from non-residential areas were found to enter and leave the community.

The results of the investigation of the three teams made the case confusing. Lu Xiaoyuan's kidnapping case is already on the seventh day. In the past 7 days, no ransom calls have been received.

Zhaohui was in Captain Wen's office, and both of them fell into deep thought, thinking about who Lu Xiaoyuan opened the door for?

"Could it be law enforcement officers? Lu Xiaoyuan opened the door for law enforcement officers. Zhaohui asked.

"What kind of law enforcement officer? Do you mean civil servants in public security, taxation, industry and commerce, national security, etc.? Captain Wen said.

"It can't be a person from taxation, industry and commerce, etc., if it is such a person, it should be during normal working hours. If it is public security and national security, it is possible, because their work is around the clock and there is no time limit. But the security guards didn't see the people from the community who came to the public security or national security? ”

"It's possible that it's in the community." The two men shouted this sentence almost at the same time.

"I'll immediately check the information of the residents in this community to see which public security personnel live in this community." Captain Wen said.

"Wait, I suggest you investigate secretly, in case of leakage, the consequences may be unimaginable, maybe this mole may be hiding in your public security team." Zhaohui reminded.

"I asked my wife to help, she is at the Banking Regulatory Bureau, and she can find out the information of buyers in this community through the bank." Brigade Wen said.

"It's a good idea."

In the afternoon of the next day, the Wen brigade got all the information about the buyers in that community. Among them, this community is inhabited by two members of the public security system. One is the deputy director of the Fan Section of the Chaoyan District Public Security Bureau, and the other is the chief of the Household Registration Section of the Purple Hat Hutong Police Station in Chaoyan District.

After the Wen brigade got the information, he drove to find Zhaohui.

"If these two police officers are the targets of investigation, there is no obvious evidence, and they do not apply to the higher-level leaders, and the investigation is carried out in this way, this is not in line with the organizational procedures." Brigade Wen spoke out about his difficulties.

"In this way, don't use the power of the public security system to do reconnaissance, I'll go to Minister Qu Wei and see if I can use the power of national security?" Zhaohui said.

"National security is a major case responsible for national security, and this kind of kidnapping criminal case is probably a bit far-fetched."

"Now that it's come to this point, I'll tell you some confidential information. I estimate that you will have to be deeply involved in the development of this case. ”

"If you think it's necessary, I don't object, you have the open scale." Brigade Wen said.

"Lu Xiaoyuan actually has a secret identity. His public identity is the CEO of 365 Company, and he also has a secret identity, he is the secretary general of the Dragon Kingdom Red Guest Alliance. ”

"What is the Red Guest Alliance?"

"You've definitely heard of hackers, or hackers. Computer technology abroad started earlier than in our country. Many Western countries have organized their own cyber forces. The hackers then became a civilian offshoot of their cyber forces. Hackers seem to be a completely civilian organization, but they are inextricably linked to the cyber forces of the world. ”

Zhaohui looked at Brigade Wen and continued

"Our country has also begun to form a cyber force. And there is a certain foundation and scale. Following the model of Western hackers, we organized the Red Guest Alliance. It's just that the difference between the Red Guest Alliance and the hacker is that the main task of the Red Guest is to defend the network of the Dragon Kingdom, and the defense is the mainstay. Their hackers are mainly sabotage, attack, and espionage. ”

"Lu Xiaoyuan is a key member of the Red Guest Alliance. He represents the country as a senior technician of global network computers, and it can be said that he is a core node of the Red Customer Alliance. He has information about the world's celebrity people. The Red Guest Alliance is developing a "Thunder Dragon" technology, once this technology is put into use, it will open a safe "golden bell jar" for the network security of the Dragon Kingdom, and this technology can also reverse track the attack information of hackers. This plan is the "Thunder" plan. ”

"Therefore, there must be a big article behind Lu Xiaoyuan's kidnapping case. I think the national security will definitely join in the investigation. ”

"Then I secretly cooperated and stopped letting people from the public security system come in, so as not to startle the snake. Surface work, I continue to push. Wen said.

"Okay, let's split up. Feel free to get in touch. ”

Zhaohui took the information given by the Wen Brigade and drove to meet Minister Qu Wei, hoping to get Minister Qu's support.

As soon as Zhaohui arrived at Minister Qu's office, he was scolded by Minister Qu first. Of course not the kind of real scolding.

"I said you stinky boy, you put both children in your mother's place, and you might as well keep one for me, who is a grandfather. Pick up both of your kids this weekend, and you're all going to come to my place for dinner. ”

"I came to tell you that our family is going to see you on the weekend, and I want to eat Auntie's cooking, and when I talk about Auntie's cooking, my saliva is about to flow out..."

"Don't fool me here, old man, I'm not dizzy yet. Let's get down to business. ”

"You're always sharp-eyed, and I'm here to ask for help."

Next, Zhaohui made a detailed report to Minister Qu on Lu Xiaoyuan's kidnapping case.

"Hey, Minister Shang Yan? Please come to me. ”

After a while, Vice Minister Zhang Shangyan arrived at Minister Qu's office. Zhaohui also reported the circumstances of Lu Xiaoyuan's kidnapping case to Vice Minister Zhang.

"Vice Minister Shang Yan, what is your opinion?"

"I think it is necessary to do an investigation into Deputy Director Fan Ke and Section Chief Zhuo Jian, if they are innocent, they can be excluded and returned to their innocence. On the contrary, if they really participated in the kidnapping case and endangered China's network information security, then don't blame the ruthlessness of the law. ”

"I agree with you too." Minister Qu said.

"Then I'll arrange it. If nothing else, I went first. ”

"There is nothing else to do, I hope this case will be solved one day sooner."

"Okay."
