After a night of silence, Xu Zheng got up early and went to the detachment because he had a lot of work today and he didn't feel at ease with other people helping him.
The list of information that the Internet police found for him yesterday added up to more than 12,000 people. This is just the three platforms of Douyin, Kuaishou, and Weibo. Their Internet police can directly apply to the platform to check the background information, and there is a special channel. , if Xu Zheng and other criminal police officers want to check the background data on the short video platform, they must first apply to their superiors, and after approval, contact the platform and wait for their reply.
Therefore, after Xu Zheng went to work, he went to the Internet Police Detachment and asked them to help investigate the video browsing records of four of the victims on social platforms. Why four people?
This is because two of them are internet celebrities, with hundreds of thousands of fans, and one video has hundreds of thousands of likes.
That number of views must not be millions!
This must not be investigated. Even if he wants to investigate, even if the Internet police want to cooperate, the platform is probably not willing to cooperate. The workload is too heavy and there is really no way to investigate.
One morning, his colleagues from the internet police detachment helped him find out that the video background browsing records of the four deceased people plus a list of more than 30,000 people.
By the afternoon, Xu Zheng had nearly 50,000 pieces of personal information on his computer. Of course, it was impossible to query all of it. He first processed the information about the suspected murderer, imported the information into the office software xls worksheet, and started Filter conditions: Male, aged between 25-35, native of Binh Giang Province.
Soon, there were more than 200 people who met the criteria. If one were to add divorce or married before screening, Xu Zheng felt that there would be even fewer people. However, he had a feeling that the murderer was not necessarily divorced. He should have known his wife. Cheating is just a matter of not choosing to divorce because of reasons such as children, parents, family, personal face, etc.
But this is just a feeling and cannot be taken seriously.
Xu Zheng then had to compare the information of these more than 200 people with the four victims. If they had the same account, this person would probably be a suspect.
Xu Zheng just finished the work in one afternoon. Handling this kind of form made him dizzy. It would be perfect if Ji Meiyue did this job. Men are really not suitable for doing these secretarial tasks.
Now he has more than thirty lists on hand, which are more in line with the targets he is looking for.
But after he finished his work, an idea suddenly came to his mind. If this man was not divorced and his wife was controlled by him, then he could use his wife's mobile phone.
this...
Xu Zheng crossed his hands behind his head and leaned back in his chair, lost in thought. The police conducted a large number of checks on divorced men in nearby cities this year, but found no suspicious persons. Moreover, men like this who continuously retaliate against cheating women, He should have been married. If he hadn't been married, he wouldn't have been so violent.
After all, anyone’s wife may have been someone else’s girlfriend.
We even played house in the kindergarten!
After thinking for a long time, he still had no clue. Finally, he decided to check these 30 people first.
At this time, the colleagues who had taken the assignment came back at the end of the day. Xu Zheng realized that it was already six o'clock in the afternoon. He didn't even pay attention to the time. He also felt a little hungry. When he stood up, he suddenly forgot about himself. Did you eat at noon? Why didn’t you have the impression of eating?
Seeing that his colleagues who had gone out all had smiles on their faces when they came back, Xu Zheng asked curiously: "Your faces are full of stories. Tell me, is there any good news?"
Lang Shaobai and Zhuang Qiang also met downstairs. If they came back at this time, they obviously didn't plan to work overtime. When they heard Xu Zheng's question, they laughed and brought up other topics.
Wei Yi usually doesn't like to talk, but now he said: "Peng Yue, the last time you bet with Xu Zheng, you lost. How about it? Are you ready with the money?"
Peng Yue, who was smiling, was a little angry when he heard this. He originally wanted to wait until the salary was paid on the 10th before mentioning this matter. If it were tonight, he secretly took a look at the Huabei quota, tsk, it is still generous enough to support the scene.
Feeling confident, Peng Yue laughed again, "It's so cold on a rainy day. Come on, I'll treat everyone to hot pot. You won't leave until you're full."
If six people go to a buffet or a whole duck feast, and if they want some drinks, it won't cost them more than a thousand dollars.
It's easy to go to eat hot pot. At most, you can have a bottle of beer and a plate of mutton per person. The portion is sufficient and you save money. It's just...
"The relationship is good, let's go, Xiao Peng treats us, Haidilao is going." Zhuang Qiang responded first, but as soon as he said it, Peng Yue's face turned green.
Wei Yi raised his head. At this time, he had to say a few words for Peng Yue, "Brother Qiang, Haidilao is too far, and there may not be a seat at this time. I think we should still stay in Fei Niu Hot Pot City, right?"
As soon as he said this, other people didn't have any objections. First, it was close, and second, this hot pot restaurant cooperated with Xu Zheng's family. This was something everyone knew. If they objected at this time, wouldn't they just have an objection to Xu Zheng?
Xu Zheng didn't expect so much, "Okay, let's order more meat and vegetables then. We can't save money for Peng Yue."
Of course, everyone was willing to eat more meat. After making noise for a long time, they quickly packed up and got ready to get off work. Suddenly, Peng Yue, who wanted to treat a guest, pointed to Zhang Yuqi's office and asked, "Hey, brothers, should we invite Captain Zhang over?"
Fei Niu Hotpot City, private room, this is the first time for the seven people from the Second Brigade to have a full dinner together. Eating hotpot is not so particular. Zhang Yuqi also came here, and she didn’t have a straight face. It was just Ji Mei who was sitting with her. Yue, I feel that I and the captain have no common voice.
It was said that they had no common voice, and before the plate of mutton was finished, everyone's conversation turned to the murderous eucalyptus on a rainy night.
This topic was brought up first by Peng Yue. After all the dishes were ordered, this guy suddenly brought up this topic, "Xu Zheng, how was your screening today? Do you need any help? Or I can join you after dinner." class?"
Looking at Peng Yue with a sincere face, Xu Zheng swallowed a big mouthful of mutton and said, "We have screened them out. There are currently 32 suspected targets. We will focus on checking tomorrow to see if there are any suspicious objects."
Xu Zheng had learned the operating skills of these office software, even though it made his head hurt after working for a whole day, "What about you, how many suspicious objects are there when you check the ex-husbands of women who have been divorced for more than a year?"
"Don't mention it. Although these information have been checked, I have screened out more than a hundred of their ex-husbands this time. They are branched out in these five cities. I just visited the household registration offices of various police stations today. As for the suspicious objects, I found nothing. .”
Xu Zheng thought for a while, "Let's do it tomorrow. The information we found will be cross-checked and compared. If both lists are included, it means that this person is very suspicious."
Divorced for more than a year, age, household registration, place of origin, city where he lives, videos he has watched online... these factors are combined together, and there is a high probability that he is the murderer. Even if the probability is small, it is worth checking.
Therefore, except for Xu Zheng and Peng Yue, who were still discussing the situation, everyone present looked at each other. This clue is very important. Should we continue eating now or go back to work overtime?
Lang Shaobai glanced at Zhang Yuqi while picking up food.
Zhuang Qiang, who usually bleated, acted like a docile sheep and started to nibble on the lettuce.
Ji Meiyue glanced at the captain quietly, and then quickly threw half a pot of coriander into the hot pot.
Wei Yi was honest and looked at Zhang Yuqi hesitantly.
Zhang Yuqi didn't even look at them, and took a few sips of the pearl milk tea Ji Meiyue bought for her, "Eat first, and then talk after eating."
In the interrogation room of the second brigade, seven people were sitting here with the smell of hot pot. Xu Zheng glared at Peng Yue. If he had known better, he wouldn't have eaten your hot pot meal. Now it's fine. He's back to work overtime. Otherwise, he would have gone back at this time. Got home and went to bed.
Peng Yue also knew that he was wrong. No one dared to deal with him in front of Zhang Yuqi along the way, but their eyes were like little knives, piercing their bodies, which was more bone-piercing than the light rain and cold wind.
After a while, the Internet video connection was established with Suyun City, and the two special teams held a remote meeting to summarize the information found today to see if there were any clues.
The two parties were polite and started working. Today, Suyun City mainly investigated the camera videos near North Taihu Park and the information of customers who rented houses in the past six months. The former did not find any suspicious persons in the videos, while the latter did investigate a person. A list of information was screened, and hundreds of people met the conditions.
There are also information that the police have investigated in five cases before. Now they only need the information of the suspicious persons found by Xu Zheng, plus the information of those who have rented a house in Suyun City or stayed in hotels, hotels, Internet cafes, and bathhouses in the past six months where they can stay overnight. The list was screened out, as well as the list of ex-husbands of divorced women investigated by Peng Yue and Wei Yi, as well as the list of online ride-hailing and taxis registered in Suyun City in the past six months.
There is also a list of suspicious people who frequently travel between Changming City and Suyun City.
In addition, various suspicious clues from the previous five cases pointed to suspicious persons.
There are various filtering conditions, as many as seven or eight, which are more in line with the police's positioning of the murderer. Even if Xu Zheng suspected, the murderer used his wife's mobile phone to browse short video platforms.
Under so many screening conditions, Xu Zheng's suspicion was true, and the murderer still couldn't escape this framework.
This is a systematic approach. Conditions are put forward from all aspects, checked one by one, and finally summarized. Not to mention, this method written in the textbook has indeed produced results.
Ji Meiyue clicked on the keyboard for more than half an hour. Finally, the faces and information of the three men appeared on her computer screen. She intercepted the information and sent it to the investigators present.
Xu Zheng opened it and saw three people, ranging in age, but their household registration information showed that they were divorced. The children of two of the men were awarded to them. Only the last person's household registration information showed that he had no children.
Having no children means you have no worries. Normally, such a condition would make people more suspicious. However, the police did not focus on investigating this. They mainly felt that the murderer's children were not enough to make him show mercy. A woman who has children and cheats will only make the murderer more merciful. Hate women even more.
