pinnacle of power

"The mobile phone was found near the crime scene. Could it be left behind by the criminal suspect?" Liu Qingyu asked excitedly.

You must know that although information such as the appearance and age of criminal suspects can be determined now, due to the lack of advanced technology, it is impossible to complete database comparison by scanning the appearance of criminal suspects to determine the ID card of criminal suspects, but only through The information on the suspect, such as dna and fingerprints, can only be confirmed after comparing the registered information with the database. Therefore, if there are other clues, it is definitely very good news for the entire case to be solved.

Thinking of this, Liu Qingyu couldn't help thinking secretly: "Now that information technology is so advanced, if we want to scan the suspect's facial features and compare it with the information in the database, and finally identify the criminal suspect, this kind of technology starts from In essence, it is not that complicated. The more difficult thing is that China has too many people. If you want to compare the database, I am afraid that the general computer is not capable of such a responsible amount of data calculation. This is the one that this technology cannot be promoted. root cause.

However, in order to achieve the goal, it is not impossible. First, everyone's appearance can generate a unique code similar to DNA. Even twins or people with similar appearance can be generated by region and date of birth. Different unique codes, when the time comes, it is only necessary for each province to establish a data center similar to cloud computing, and then through the national cloud computing center, the real data computing will be handed over to professional departments. Public security departments in prefectures, cities, and even towns can scan the suspect's appearance anytime, anywhere to determine his true identity.

Although the workload of this project is not small, once it is realized, it will benefit the public security department endlessly.

Thinking of this, Liu Qingyu began to think in the depths of his heart. It seemed that he needed to write a report and submit it directly to the Provincial Public Security Department or even the Ministry of Public Security.

While Liu Qingyu was thinking about it, Cheng Yonggang had already replied on the other end of the phone: "Director Liu, we have just discovered this phone and are currently tracking down the owner of the phone. The owner of this phone has been locked. We have obtained the latest contact information of the girl through the telecommunications department and are contacting her to find out why this mobile phone appeared at the scene of the crime.”

Liu Qingyu nodded in satisfaction: "Okay, Lao Cheng, you have done a good job. Keep following up and try to find more clues about the suspect as soon as possible."

After hanging up the phone, Liu Qingyu fell into deep thought again, because according to his analysis, judging from the criminal suspect's sophistication at the scene of the crime and his careful choice of escape routes, he should be a veteran. It is said that there should not be the possibility of leaving an extremely identifiable item such as a mobile phone at the scene of the crime, but there is a mobile phone at the scene of the crime. Is this mobile phone left by the murderer accidentally, or is it intentional? The ones left behind to carry out the suspicion formation, or the ones discarded by others at the scene.

Two hours later, Liu Qingyu received a report from Cheng Yonggang again: "Director Liu, we have figured out the matter of this mobile phone. The owner of this mobile phone is Ruan Yuyan, a sophomore female student. This mobile phone belongs to her. I lost it while shopping more than a week ago. Therefore, according to our analysis, since this mobile phone appeared at the scene, there are two possibilities. One is that the thief who stole the female college student appeared near the scene, and the other is that the thief took the mobile phone. It has been resold, and the buyer bought the stolen mobile phone from a mobile phone store and appeared at the scene. According to our investigation and visit to the scene, there are spectators near the crime scene. Under normal circumstances, it is impossible for anyone to watch the scene. If the mobile phone is thrown away at any time, there are two other possibilities for why this mobile phone appeared at the scene. One is that the suspect accidentally or even deliberately discarded the mobile phone at the scene. Another possibility is that the mobile phone is the result of Chen Tianjie being killed. It fell from him unintentionally."

Liu Qingyu nodded when he heard the words: "Then, what happened to this mobile phone?"

Cheng Yonggang said: "Later, we sent people to visit the most famous mobile phone communication street in Lanshan City, and finally confirmed in a small shop that sells and recycles second-hand mobile phones that the mobile phone lost at the scene was from their mobile phone. It was sold in the store, and this mobile phone was recycled by them just a week ago. The seller is a young man in his 20s. According to him, this young man often comes to sell second-hand mobile phones, so , it is basically certain that this young man should be a thief, but this young man is not the point. We have in-depth understanding with the owner of the mobile phone shop and learned that the person who bought this second-hand mobile phone is a man named Sun Jinxing, who is about When he was around 30 years old, he spoke with a local accent. Later, we showed the arrest warrant to the mobile phone shop owner, and the mobile phone shop owner was sure it was this person.”

Hearing that Cheng Yonggang confirmed that the mobile phone actually belonged to the criminal suspect, Liu Qingyu was overjoyed and immediately asked: "Since the mobile phone shop owner knows the name of this person, does he know the real identity of this person?"

Cheng Yonggang immediately said: "Yes, he said that he had met this buyer a few times before, bought a mobile phone from him before, and asked him to issue a license, so he knows the real name of this person, and he is still here. We work in a martial arts school in Lanshan City. Now we have confirmed the person's ID card, home address and other information through the person's name, and have sent someone to their house to look for it. His wife said that he was on a business trip last night. No, his wife doesn't know exactly where to go."

Liu Qingyu's expression darkened when he heard the words, because if this Sun Jinxing stayed in Lanshan City, it would be relatively easy for the Lanshan City Public Security Bureau to catch him, but once he left Lanshan City If it is in the city, it will be difficult to catch him. After all, Huaxia is so big, and it is not that simple to find someone who wants to hide.

Liu Qingyu frowned and said: "Okay, Lao Cheng, then your group will continue to follow up on this clue immediately, looking for the criminal suspect's whereabouts, especially if you are going to long-distance passenger stations, railway stations and other transportation hubs." Check the identity information of this Sun Jinxing to see if he left Lanshan City by car."

Cheng Yonggang immediately nodded to express his understanding.

After hanging up the phone, Liu Qingyu immediately called Cui Zhenhua and reported the latest news to Cui Zhenhua.

After Cui Zhenhua heard the news, he immediately rushed to Liu Qingyu's office.

Cui Zhenhua looked at Liu Qingyu with a smile and said, "Comrade Liu Qingyu, now that the suspect has been identified, what are your plans for the next step?"

Hearing Cui Zhenhua's question, Liu Qingyu smiled slightly: "Director Cui, does your question count as an exam?"

Cui Zhenhua smiled and said, "Forget it, I want to hear your deployment."

Liu Qingyu said with a smile: "Director Cui, my deployment is that Cheng Yonggang and his team will continue to follow up until the suspect is caught. At the same time, the second team led by Comrade Zhou Shangwu will continue to focus on Chen Tianjie's social relations." As for the third team, after comprehensively extracting all kinds of on-site evidence, they will focus on tracking down the suspect Sun Jinxing and cooperate with the first team to catch Sun Jinxing as soon as possible."

Cui Zhenhua laughed and said, "Since the suspect is confirmed to be Sun Jinxing, why do we need the second team to continue the investigation?"

Liu Qingyu said: "Director Cui, you are testing me again. Although we have identified Sun Jinxing as the suspect who killed Chen Tianjie, the problem is that there seems to be no relationship between Sun Jinxing and Chen Tianjie. One worked in the martial arts school, the other worked in the Transportation Bureau, and we have already conducted an investigation and confirmed that there is no intersection between Sun Jinxing and Chen Tianjie. So, Sun Jinxing's criminal motive for killing Chen Tianjie does not exist. , since there is no interest relationship or conflict, there is only one possibility, and that is that Sun Jinxing committed murder for money. Since it is for money, it means that there is someone who hires the murderer behind Sun Jinxing, so even if he is caught Sun Jinxing, this case cannot be closed, but can only be closed after finding the person behind the scenes."

Hearing Liu Qingyu's analysis, Cui Zhenhua nodded with satisfaction: "Well, not bad, not bad, Liu Qingyu, you really surprised me. With you in Lanshan City, I guess the social security in the future should be better. There's been a huge improvement."

Hearing this, Liu Qingyu immediately smiled and said modestly: "Director Cui, you think highly of me too. The social security of Lanshan City has a long way to go."

As Song Weiguo's team joined the team to track down Sun Jinxing, the operational efficiency of the entire Lanshan City Public Security Bureau was improved again. Especially with the cooperation of the provincial department, everyone quickly confirmed through identity information that Sun Jinxing had fled to Tongda, the provincial capital. However, although he hid in a small hotel, in the face of the strong action capabilities of the public security system, his lurking could not escape the law in the end, and he was finally caught at around 1:[-] the next morning while he was asleep. Cheng Yonggang led his men to capture him directly, and escorted him back to Lanshan City.

At this moment, the distance from the incident is only 3 days.

When the news of Sun Jinxing's capture reached Zhou Junhao's ears, Zhou Junhao and He Yuxiang were sitting in the office drinking tea and talking about the work of the city government.

Upon hearing the news, He Yuxiang's expression turned ugly, and he said with some displeasure: "Mayor Zhou, I really didn't expect Liu Qingyu to be so lucky to catch the suspect in only three days since the crime happened. It seems , our goal of cleaning up Liu Qingyu by solving the case within a time limit is impossible to achieve."

However, Zhou Junhao's face was calm, with a cold smile on the corner of his mouth: "It can't be achieved, who said it, why don't I know."

He Yuxiang was taken aback for a moment, and looked at Zhou Junhao in confusion,
