"The mobile phone was found near the crime scene. Could it be left behind by the criminal suspect?" Liu Qingyu asked excitedly.
You should know that although it is now possible to determine the appearance, age and other information of a criminal suspect, because the technical level is not developed enough, it is not possible to complete database comparison by scanning the suspect's appearance to determine the suspect's ID card. The suspect's information can only be confirmed after comparing DNA, fingerprints and other registered information in the database. Therefore, if there are other clues, it will definitely be very good news for the entire case.
Thinking of this, Liu Qingyu couldn't help but secretly think: "Now that information technology is so advanced, if we want to scan the facial features of criminal suspects and compare them with the information in the database, and finally identify the criminal suspects, this technology will never be used." In essence, it is not that complicated. The more difficult thing is that China has too many people. If you want to compare databases, I am afraid that ordinary computers will not be able to handle the amount of data calculations. This is the reason why this technology cannot be promoted. root cause.
However, it is not impossible to achieve the goal. First, each person's appearance can generate a unique code similar to DNA. Even twins or people with similar looks can be generated by region and date of birth. Different unique codes, when the time comes, only each province will need to establish a data center similar to cloud computing, and then through the national cloud computing center, the real data calculations will be handed over to professional departments. In this way, each province will Public security departments in prefectures, cities and even towns can determine the true identity of criminal suspects by scanning their faces anytime and anywhere.
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 make constant calculations deep in 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.
Just as 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 the owner of the phone. We have already locked the owner of this phone to a man in his 20s. The girl is about 6 years old. We have obtained the girl’s latest contact information through the telecommunications department and are contacting her to understand why this mobile phone appeared at the crime scene.”
Liu Qingyu nodded with satisfaction: "Okay, Lao Cheng, you have done a good job. Continue to follow up and try to find more clues and information 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 sophistication shown by the criminal suspect at the scene of the crime and his careful choice of escape routes, he should be a veteran. Logically speaking, he should be a veteran. It is said that there should not be a possibility of leaving an extremely identifiable item such as a mobile phone at a crime scene, but a mobile phone happened to appear at the crime scene. Was this mobile phone left by the murderer accidentally, or was it deliberately left behind by the murderer? The ones that were left behind to create a mystery, or maybe others abandoned them at the scene.
Two hours later, Liu Qingyu received another report from Cheng Yonggang: "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 was stolen by her in It was lost 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 once 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 showed up at the scene. According to our investigation and visit to the scene, there are people watching the scene near the crime scene. Under normal circumstances, it is impossible for anyone to watch the scene. Then there are two other possibilities for why this mobile phone appeared at the scene. One is that the mobile phone was accidentally or even deliberately discarded at the scene by the criminal suspect. The other possibility is that this mobile phone was used by Chen Tianjie when he was murdered. It fell from his body accidentally during the killing."
Liu Qingyu nodded when he heard this: "Then what happened next, 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 exactly 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, Basically, it is certain that this young man should be a thief, but this young man is not the focus. Through in-depth understanding with the mobile phone store owner, we learned that the person who bought this second-hand mobile phone was a person named Sun Jinxing, who was about 30 years old. He was about thirty years old and spoke with a local accent. Later, we showed the wanted poster to the mobile phone shop owner, who was sure it was this person."
Hearing that Cheng Yonggang confirmed that the mobile phone really belonged to the suspect, Liu Qingyu was immediately overjoyed and immediately asked: "Since the mobile phone store owner knows this person's name, does he know this person's true identity?"
Cheng Yonggang immediately said: "Yes, he said that he had met this buyer several times before. He had bought a mobile phone from him before and asked him to open an invoice. Therefore, he knew this person's real name, and he was still here. We work at a martial arts school in Lanshan City. Now we have confirmed this person's ID card, home address and other information through his name, and have sent people to their home to look for him. His wife said that he was on a business trip last night. Yes, his wife doesn’t know where exactly he is going.”
Liu Qingyu's face suddenly darkened when he heard this, because if Sun Jinxing stayed in Lanshan City, it would be easier for the Lanshan City Public Security Bureau to catch him, but once he left Lanshan City If he is in the city, it will be difficult to catch him. After all, China is so big, and if you want to find someone who is willing to hide, it will not be that simple.
Liu Qingyu frowned and said: "Okay, Lao Cheng, your group will immediately follow up on this clue to find the suspect's whereabouts, especially to long-distance bus stations, train stations and other transportation hubs. Please check Sun Jinxing's identity information and 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 next plans?"
Hearing Cui Zhenhua's question, Liu Qingyu smiled slightly: "Director Cui, is this question of yours considered an exam?"
Cui Zhenhua smiled and said: "Forget it, I want to hear your plan."
Liu Qingyu said with a smile: "Director Cui, my plan is that Cheng Yonggang and his team will continue to follow up until the suspect is caught. At the same time, the second team headed by Comrade Zhou Shangwu will continue to focus on Chen Tianjie's social relations. The investigation was launched, and as for the third team, after comprehensively extracting all kinds of on-site evidence, they turned their attention to tracking the criminal suspect Sun Jinxing and cooperated with the first team to catch Sun Jinxing as soon as possible."
Cui Zhenhua said with a smile: "Since the suspect is confirmed to be Sun Jinxing, why do we need a 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 does not seem to be any relationship between Sun Jinxing and Chen Tianjie. One of them works in a martial arts school, and one works in the Transportation Bureau. Moreover, we have also conducted an investigation and confirmed that there is no intersection between Sun Jinxing and Chen Tianjie. Therefore, the criminal motive for Sun Jinxing to kill Chen Tianjie does not exist. , since there is no interest relationship or conflict, there is only one possibility, that is, Sun Jinxing committed the murder for money. Since it is for money, this means that there is someone hiring murderers behind Sun Jinxing, so even if he is caught Sun Jinxing, this case cannot be closed, but only by finding the person behind it."
Hearing Liu Qingyu's analysis, Cui Zhenhua nodded with satisfaction: "Well, not bad, Liu Qingyu, you really surprised me. With you in charge of Lanshan City, I estimate that the social security in the future will be better." There has been a big improvement.”
Upon hearing this, Liu Qingyu immediately smiled and said modestly: "Director Cui, you think highly of me too much. There is a long way to go to ensure social security in Lanshan City."
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 once again improved. Especially with the cooperation of the provincial department, everyone quickly determined through identity information that Sun Jinxing had fled to Tongda, the provincial capital. He lurked in the city. However, although he hid in a small hotel, in the face of the powerful operational capabilities of the public security system, his lurking could not escape the law. He was eventually arrested while sleeping at around 1 a.m. the next day. Cheng Yonggang led his men to capture him directly and escorted him back to Lanshan City.
At this moment, it was only 3 days before the incident occurred.
When the news of Sun Jinxing's arrest reached Zhou Junhao's ears, Zhou Junhao was sitting in the office with He Yuxiang, drinking tea and talking about the work of the municipal government.
After hearing the news, He Yuxiang's face looked a little ugly, and he said unhappily: "Mayor Zhou, I really didn't expect Liu Qingyu to be so lucky. He caught the suspect just three days after the incident. It seems that , there is no way we can achieve our goal of dealing with Liu Qingyu by solving the case within a time limit."
Zhou Junhao, however, had a calm expression and a cold smile on his lips: "It can't be achieved. Who said that? Why didn't I know?"
He Yuxiang was stunned and looked at Zhou Junhao with some confusion.
