The story of police officer Yang Qianfeng

Chapter 402 It Really Worked
Using scientific and technological means to investigate and solve crimes has actually been going on in the kingdom of heaven, but it has to go through strict approval procedures.Mobile phones have not been widely used in heaven for a long time, and there is no uniform and standardized procedure for using mobile phone information to investigate and solve crimes. However, public security organs in some coastal developed areas have already explored and used mobile phones and their methods in response to changes in criminal methods. Information technology has carried out investigations and achieved good results with twice the result with half the effort, but inland or underdeveloped provinces have not done this kind of work, not to mention the county-level public security organs in these places, even the provincial-level public security organs have not yet Practice formally.So when Hong Lifei suddenly saw Yang Qianfeng, a typical inland province with relatively backward economic conditions, boldly put forward this investigative idea, he was of course very excited.

However, for a long time, the public security organs have used science and technology to investigate and solve crimes, only as a means of investigation, and some audio-visual materials related to crimes obtained cannot be directly used as evidence. With the development of the situation and the advancement of technology, the kingdom of heaven These laws have been fully taken into consideration when the law was enacted. For example, the Criminal Procedure Law of [-] (that is, the Criminal Procedure Law after the first revision of the First Criminal Procedure Law of the Chinese Dynasty in [-]) clearly stipulates that Audio-visual materials are one of the evidences, but electronic materials have not yet been entered into the law as evidence.Yang Qianfeng believes that in the near future, electronic data will definitely be included in the law as evidence.Therefore, the mobile phone data in the hands of Zhang Lihua and others has identified the suspect, but the data itself cannot be directly used as evidence, but can only serve for investigation.

Zhang Lihua and Xu Yan led three investigators from the criminal police team of the Sunshine Responsibility Area to work continuously for two days and two nights, and then screened the information in the primary selection, and further determined the key points in the screened information to screen one by one. After screening, there were five mobile phone owners Suspicious, after further investigation, three suspicious mobile phones were ruled out, and the suspicion of committing crimes by the owners of the remaining two mobile phones rose rapidly.This made Hong Lifei, Zhang Lihua, Xu Yan and others very excited. Shi Lei also temporarily forgot that this investigation idea was proposed by Yang Qianfeng, so he ordered two groups of people to go to the residences of the owners of the two mobile phones. Carry out ground investigation.

There is no way out in the three poor waters, and there is another village in the shadow of the willow. After identifying the two key suspects, Zhang Lihua can no longer bear the excitement in her heart. She wants to tell Yang Qianfeng the news and let him share the joy. So he called his home phone, and the ringtone woke up Yang Qianfeng and Chen Laixiang who were sleeping soundly.

Since Yang Qianfeng went to Wenming to work, the phone at home seldom rang late at night. Yang Qianfeng and Chen Laixiang have already adapted to this kind of life. They both feel that it is a happy thing to wake up naturally every night. The phone rang once after they went to sleep, and only after answering the phone did they realize that they had made a wrong call. Yang Qianfeng thought that someone must have made a wrong call this time, so he picked up the phone and said hello, but Zhang Lihua's excited voice came. Voice: "I have good news for you, maybe we really succeeded this time."

As soon as Yang Qianfeng heard it, he knew what she meant, and said happily: "Really? Congratulations, you have worked hard!"

When Yang Qianfeng got up and leaned on the bed to answer the phone, Chen Laixiang also got up. She heard Zhang Lihua say it was successful, but she didn't know what it meant, and Yang Qianfeng's tone seemed to know, so she asked curiously: "It's midnight, what is it?" thing!"

Zhang Lihua heard Chen Laixiang's voice and immediately said: "I'm sorry, I was too excited and broke the sweet dreams of the two of you, but I couldn't control myself and thought I had to tell you as soon as possible so that you could share Take a look at the joy that doesn't come easily."

Yang Qianfeng said: "It's really not easy to find key criminal suspects in so much data, and it's done manually. By the way, you have identified a few key points, and where are they from?"

Zhang Lihua said: "Two are identified, one is from J City in Xijiang Province, and the other is from City Y in Jiangsu Province. Although they are from different directions, the distance from the two places to our county is about the same distance. The analysis of time and information is very similar. Like, especially the guy from J City, Xijiang Province, is a driver and has a private car, while the guy from Sujiang is also a driver, but he doesn’t have a private car. Of the two key people, I feel more for the guy from Xijiang Interested, so I volunteered to go to Xijiang to do the landing verification work.”

Yang Qianfeng said: "You did a good job. By the way, if you can check the time of his entry and exit at the toll booth along the way, it will be even more perfect if you can get the video data. It will be of great help to the interrogation."

Zhang Lihua has been busy checking the information on her mobile phone, and has not considered this issue. After being reminded by Yang Qianfeng, she thinks it is very important, and said happily: "Thank you for your concern. You are really good at predicting things and winning a thousand miles. You can help us with ideas, if Director Hong Lifei didn’t support us, we would definitely not be able to solve this case.” Speaking of this, she suddenly thought of Shi Lei’s attitude and reaction that day, and said, “By the way, let me tell you something, that day I sent all the phone information to you. When the data was retrieved and analyzed, Shi Lei thought that we were not doing our job properly and wasting time. Later, when he heard that it was your idea, he got angry and said that you were meddling. Fortunately, Deputy Chief Hong Lifei was present at the time, and he affirmed this investigative idea. And personally participated in the data analysis, Shi Lei had no choice but to support this in the end, now that the results have been produced, he is also refreshed, dancing happily, probably forgot about you."

Yang Qianfeng smiled and said: "I don't care about his attitude towards me at all, as long as it is beneficial to solve the case, and can save you from taking detours, and solving the case as soon as possible is what I want. Fortunately, with Hong Lifei's support, there will be so soon." Now that you have a clue, come on, I hope you catch the murderer as soon as possible."

"Don't worry, we will work hard." After she finished speaking, she paused and continued: "It seems that He Fenfang didn't see what she wanted at Laixiang that day, and besides, Shi Lei told her the old news as news, which made her feel No face, I think she must have talked about Shi Lei, and she said it seriously, so when Shi Lei heard your name that day, I was furious. It was the first time I saw that expression. He wouldn't let us go any further down the line."

Yang Qianfeng said: "Let's not talk about him, remember, no matter it is in Xijiang Province or Jiangsu Province, as long as it is locked, the video of the toll station at the key node on the road must be called."

Zhang Lihua nodded her head vigorously and said loudly: "Yes, firmly follow the instructions of the leader." After finishing speaking, she said in a low voice: "Tell Laixiang, she is so powerful, she subdued Mrs. He in a reasonable and restrained manner. Admire her!"

Chen Laixiang was actually listening to the phone all the time, and after hearing Zhang Lihua's words, he said happily in front of the microphone: "Thank you for your praise, don't admire me, I still admire you in my heart! You are so capable, and you will soon solve another big case."

Yang Qianfeng waited for Chen Laixiang to finish speaking and said: "Stop admiring each other, go back to rest early, and do what you need to do to make a good business trip!"

Zhang Lihua laughed loudly and said, "Laixiang, do you understand your Ah Feng's meaning? I'm hanging up the phone."

In the afternoon of the next day, with the great support and cooperation of the Xijiang Public Security Bureau, the suspect was successfully arrested, and the case of murder and throwing the body thousands of miles away was solved in one fell swoop.
