I don't want to solve the case when I'm a little policeman.

Chapter 253 Systematic screening of information

Having nothing to say all night, Xu Zheng got up early in the morning and went to the detachment, because he had a lot of work today, and he was worried about other people helping him.

The list of information that the Internet police helped him check yesterday totaled more than 2000 people. These are just the three platforms of Douyin, Kuaishou, and Weibo. Their Internet police can directly apply to the platform to check the background information. There is a special channel. If criminal police like Xu Zheng want to check the background data on the short video platform, they should first apply to their superiors, contact the platform after approval, and wait for their reply.

So, 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' social platforms. Why were there four?
This is because two of them are Internet celebrities big and small, with hundreds of thousands of fans, and even hundreds of thousands of likes for a video.

That must not have millions of views!
This must not be investigated, even if he wants to investigate, even if the Internet police want to cooperate, the platform is probably unwilling to cooperate, the workload is too heavy, and there is really no way to investigate.

One morning, colleagues from the Internet Police Detachment helped him find out that there were more than 3 people in the video background browsing records of the four deceased.

In the afternoon, there were nearly 25 pieces of personal information on Xu Zheng's computer. Of course, it was impossible to check them one by one. He first processed the information on the suspected murderer's side, imported the information into the XLS worksheet of the office software, and started Screening criteria: Male, aged between 35-[-], native place of Binh Giang Province.

Soon, there were more than 200 people who met the criteria. Xu Zheng felt that there would be even fewer people if he added a divorce or married to the screening. However, he had a feeling that the murderer was not necessarily divorced, but knew his wife. Cheating, because of reasons such as children, parents, family, personal face and other reasons did not choose to divorce.

But this is just a feeling, not to be taken seriously.

Then Xu Zheng had to compare the information of these 200 people with the information of the four victims. If they had the same account, this person was probably a suspect.

In one afternoon, Xu Zheng just finished the job. Handling this kind of form made him dizzy. It would be perfect if this job was handed over to Ji Meiyue. Men are really not suitable for these secretarial things.

Now he has more than 30 lists on hand, which are more in line with the target he is looking for.

It's just that after he finished his work, an idea suddenly popped up in his mind. If this person was not divorced and his wife was controlled by him for personal freedom, then he could use his wife's mobile phone.

This.
Xu Zheng crossed his hands behind his head, leaned back on the chair and fell into deep thought. The police have checked a large number of divorced men in these nearby cities this year, and found no suspicious persons. He should have been married, if he wasn't married, he shouldn't be so angry.

After all, any wife may have been someone else's girlfriend.

Kindergarten also played house!
After thinking for a long time, he still had no idea, and finally he decided to check the more than 30 people first.

At this time, all the colleagues who had received the assignment came back at the end of work, and Xu Zheng realized that it was already six o'clock in the afternoon. He didn't even pay attention to the time, and he felt a little hungry. Have you eaten at noon? Why don't you have the impression of eating?
Seeing the smiles on the faces of the colleagues who had gone out, Xu Zheng asked curiously, "Your faces are full of stories. Tell me, is there any good news?"

Lang Shaobai, Zhuang Qiang and the others also met downstairs, and they obviously didn't intend to work overtime if they could come back at this point. When they heard Xu Zheng's question, they laughed loudly, leading to 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 have lost. How about it, is the money ready?"

Peng Yue, who was smiling, felt a little furious when he heard it. He wanted to wait until the tenth to pay his salary before mentioning it. If it was tonight, he secretly took a look at the Huabei quota, tsk, it's still wide enough to support the scene.

With enough confidence, Peng Yue laughed again, "It's raining and cold, let's go, I'll treat everyone to hot pot, the kind that you won't be allowed to slip away until you're full."

If the six of us go to the buffet or the whole duck banquet, and if we have some wine, we can spend thousands of dollars.

Going to eat hot pot is much easier, at most one bottle of beer per person, one plate of mutton per person, the portion is sufficient, and it saves money, but
"That's a good relationship, let's go, Xiao Peng treats guests, and Haidilao will go." Zhuang Qiang responded first, but Peng Yue's face turned green as soon as he said it.

Wei Yi raised his head, and now he has to say a few words for Peng Yue, "Brother Qiang, Haidilao is too far away, and there may not be any seats at this time. In my opinion, let's go to Fat Niu Hot Pot Town, right?"

When he said this, other people didn't have any objections. One was that it was close, and the other was that this hot pot restaurant cooperated with Xu Zheng's family. This was something everyone knew. If he objected at this time, wouldn't it mean that he had a problem with Xu Zheng?

Xu Zheng didn't think about it so much, "Okay, let's order more meat dishes, we can't save Peng Yue money."

Of course, everyone wanted to eat more meat. After booing for a long time, they quickly packed up and got ready to leave work. Suddenly, Peng Yue, who wanted to treat guests, pointed to Zhang Yuqi's office and asked, "Hey, brothers, should we invite Team Zhang to come over?"

Fat Niu Hot Pot City, private rooms, the second brigade of seven people is the first full-staff dinner party, eating hot pot is not so particular, Zhang Yuqi also came here, and she didn't keep a straight face, just Ji Mei who was sitting next to her Month, I feel that I have no common voice with the captain.

It is said that there is no common voice, and the plate of mutton has not been finished yet, and everyone's conversation has turned to the rainy night murder case.

This topic was first brought up by Peng Yue. After the dishes were ordered, this guy suddenly brought up this topic, "Xu Zheng, how is your screening today? Do you need help? Otherwise, I will accompany you to join the meeting after dinner." class?"

Looking at Peng Yue who was full of sincerity, Xu Zheng swallowed a big mouthful of mutton, "We have screened out, there are currently 32 suspected targets, and we will focus on the investigation tomorrow to see if there are any suspicious targets."

Xu Zheng had already learned the operation skills of these office software, although it gave him a headache all day long, "What about you, how many suspicious objects do you find out about the ex-husbands of women who have been divorced for more than a year?"

"Don't mention it, although I have already checked the information, this time I screened out more than 100 of their ex-husbands. The branches are in these five cities. Today, I just went to the household registration offices of various police stations. As for suspicious objects, I found nothing. "

Xu Zheng thought for a while, "Tomorrow, the information we both found is the same through cross-comparison. If there are two lists, it means that this person is very suspicious."

Divorce for more than one year, age, household registration, place of origin, city of life, and watching videos on the Internet are all combined together. There is a high probability that the murderer is the murderer. Even if the probability is small, it is worth investigating.

So, except for Xu Zheng and Peng Yue who were still discussing the case, everyone else looked at each other. This clue is very important. Should we continue to eat now or go back to work overtime?
Lang Shaobai glanced at Zhang Yuqi while picking up vegetables.

Zhuang Qiang usually bluffed like a docile sheep at this time, and gnawed the lettuce directly.

Ji Meiyue glanced at the captain quietly, and then hurriedly 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 that Ji Meiyue bought for her, "Eat first, we'll talk after we finish."

In the judgment room of the second brigade, seven people sat here with the smell of hot pot. Xu Zheng glared at Peng Yue. Went home to bed.

Peng Yue also knew he was wrong, and everyone didn't dare to clean up Zhang Yuqi in front of him along the way, but everyone's eyes were like small knives piercing his body, which was more piercing than this light rain and cold wind.

After a while, I connected with Suyun City through online video, and the two task forces held a remote meeting to summarize the information found today to see if there were any clues.

The two parties were polite and started to work. Today, Suyun City mainly investigated the camera recordings near the North Taihu Lake Park, and the information of customers who rented houses in the past six months. The former did not find any suspicious persons in the recordings, and the latter did investigate. A list of information, through the screening, there are hundreds of people who meet the requirements.

There are also the information that the police have investigated in the five previous investigations. Now we only need the information of the suspicious persons that Xu Zheng found here, plus those who have rented a house in Suyun City for the past six months or lived in hotels, hotels, Internet cafes, and bathhouses. The selected list includes the list of divorced women's ex-husbands investigated by Peng Yue and Wei Yi, and the list of online car-hailing cars and taxis registered in Suyun City in the past six months.

There is also a suspicious list of people who often travel between Changming City and Suyun City.

In addition, the suspicious persons pointed to by various suspicious clues in the previous five cases.

There were so many things, there were as many as seven or eight screening criteria, all of which were more in line with the police's positioning of the murderer. Even as Xu Zheng suspected, the murderer used his wife's mobile phone to browse the short video platform.

Under so many screening conditions, Xu Zheng's suspicion was true, and the murderer still couldn't escape this framework.

This is systematic case handling. Conditions are put forward from all aspects, checked one by one, and finally summarized. Not to mention, this method written in textbooks does have results.

Ji Meiyue clattered on the keyboard for more than half an hour, and finally the avatars and messages of the three men appeared on her computer screen. She intercepted the messages and sent them to the investigators present.

Xu Zheng opened it and saw that there were three people of different ages, but their household registration information was all divorced, and two of the men's children were awarded to them. Only the last one, whose household registration information showed that he had no children.

It is said that such conditions are more suspicious, but the police did not focus on investigating this, mainly because they felt that the murderer's children were not enough for him to show mercy, and a woman who had children and cheated would only make the murderer Hate women even more.
