Bao Zhan came to work and heard that he didn't catch up with the boss the day before, which was a remorse, but I was very happy to hear that their group is now under the boss's line to investigate the case.

Today's beautiful rotation rest, she hasn't found time to mention the incident in the car yesterday to others, and the bureau has been busy recently, so she has no time to gossip.

The three of them met, looked at the direction of Captain He's column, and divided the work by themselves: Bao Zhan first went to ask Cheng Chengyuan's family and colleagues in the company, why did he turn off his work on the afternoon of the 22nd, and whether he had an appointment with a beautiful woman; Da Zhuang went to follow the source of the wine, first roughly check what shops sell the winery's red wine, and see if it is difficult to sift it; As for Ding Yuan, he stayed in the bureau to follow up on the progress of the information technology side, and once he found the source of those suspicious forum accounts, he went to find the people behind the posts and comments.

Bao Zhan's side was the first to finish things, but Ying Mingyu was not there, he had nowhere to reply, and he didn't know what the boss asked to do. After he was busy, he went to Da Zhuang to help him check the source of the wine, this line is troublesome, even if he really finds the store, this kind of store is generally anonymous sales, and it is difficult to find a buyer.

Ding Yuan's progress was okay, except for Lily, who was in the first place, and the first five accounts of information technology quickly found two. In the morning, Ding Yuan went to find one of them, first went to the address of his home, and determined that it was a girl who rented there; Then I found a place to work, and it was a girl who worked at the airport as a salesman.

The girl is quite young, she is an angry young man, she is not tired from work, and she likes to go to the forum to speak out after work. Ding Yuan chatted with her for a while, got the time evidence of the thirteenth and twenty-third, recorded all kinds of information about her, and went back to the bureau to check the second person.

The second person named Ding Yuan was shocked, the address given by the technical department was in a university, and he went to the place where the school allocated the network, and it took a lot of trouble to find the female dormitory with that IP address. Fortunately, there is no big holiday now, and there are no festivals, and when he found it, the school classes during the day were over, and he looked for this dormitory.

There are four people in a dormitory, each with a computer, even if Ding Yuan doesn't believe that this girl who is in college can commit that kind of serial murder, he still has to maintain a non-discriminatory attitude and remain suspicious and investigate according to the process. There was a person in this dormitory who went out, but fortunately, after he asked, someone quickly admitted it. Ding Yuan couldn't help sighing, she was a girl who looked very quiet, she looked more petite than Lu Qianqian, but she didn't expect to speak quite horizontally on the Internet.

Fortunately, the other two in their dormitory can give her time witnesses, this girl usually rarely goes out, even if they dare not guarantee it on the 13th, but on the 23rd it is this week, and they dare to guarantee that she is in the dormitory every night. Ding Yuan educated them a few more words, and they should also pay attention to proportions and keep their senses when speaking on the Internet, so he went back to the bureau to resume his life, he estimated that the boss should come.

Ying Mingyu was the same as the day before yesterday, he went out after dinner, this time Lu Qianqian prepared a snack in advance, although it was a cold biscuit cake, but it was also served with hot tea, and it could be supper at night.

Ying Mingyu took the things and explained: "Don't come to the bureau tomorrow, you rest at home, and I'll give you a holiday." ”

Lu Qianqian waved his little hand at him.

He doesn't sleep all night, he always takes turns to rest during the day, Lu Qianqian can't stand it, and he doesn't allow her to help, does he want to exhaust himself to death?

Ying Mingyu entered the office this time, and everyone in the group was waiting for him, even Meimei, except for Lu Qianqian.

"Boss, I've asked. Boss Cheng had dinner with friends from the cooperative company at noon that day, and took two colleagues from the company to go together, and met a reporter halfway, and the two had a conflict and quarreled, and Boss Cheng was in a bad mood and went home after eating. The family also went to ask, and Boss Cheng returned home at two o'clock, but before dinner, he went out again and didn't eat dinner at home. ”

"Did the reporter ask his name, why did you quarrel?"

Bao Zhan smiled proudly, he knew the boss's habit, and it was better to ask in detail about everything: "I asked, my name is Wei Feng, I came to the bureau to ask before." said that he interviewed the boss before, asked very embarrassing questions in person, and later wrote some derogatory articles and reports, and the two of them had a deep grudge. For this matter, Boss Cheng reported this reporter to the newspaper at the time, and after meeting it on the 22nd, he called to report it, saying that the reporter was holding on to him and was still following him. ”

"Boss, do you think this Wei Feng is deliberately following?" Although Ding Yuan felt that most of it was Cheng Chengyuan's psychological effect to find the reason for the matter, he couldn't say for sure, all the clues on his side were all involved in Wei Feng.

"I'll find out next time I invite him to ask, and then I'll go on." Ying Mingyu did not draw conclusions. He remembered that when Wei Feng operated the computer last night, he used his left hand, and besides, he was a man, and he was a fool of the murderer.

Da Zhuang took over: "I asked a few places that sell wine, and the statement is similar, this winery is not bad, but the next year is much better than this year, and it doesn't sell much if you buy less." Most of them are bought casually by people who don't know how to do it, and they are not old customers, and they probably won't buy it back, they don't do special registration, and at most they can find out when the inventory was reduced. ”

"Don't follow this line yet, maybe I'm thinking too much." Ying Mingyu admitted a soft mistake, he didn't think there was a problem with this line in his heart, but now there is no manpower, it is too labor-intensive here, and it will be difficult to find it for a while.

"Boss, the technical people here in the forum have been checking, I ran two today, and there is no suspicion." Ding Yuan told the situation of the two people, and the information was also given to Ying Mingyu, "I went over there and asked again when I came back just now, and two of the remaining four are foreign numbers, which are difficult to find, and one is a foreign IP, which is basically impossible to find." ”

"What about the 'pure Lily', what's going on?" Ying Mingyu wondered, he said that he had started with this first, how could Ding originally run other accounts.

"Boss, there's really a problem with this person, the technical department said that this number is a mobile IP, maybe it's a converter at home, anyway, it's all professional terms, that is, the address has been changing. It's difficult to check, but one thing is certain that this number is local, and all the addresses she changed are from the city. ”

"Heh, since she has a way to change, why don't she change to a foreign country, a foreign place, but only in this city?" Ying Mingyu was puzzled.

"It's... I didn't expect it, it's really strange, if she changes her address in a foreign country, we can't figure out where she is, but she changes all her local ...... Could it be that she is actually out of town? ”

No matter how you think about this approach, it is a bit deliberate, Ying Mingyu did not delve into it further, nor did he discuss it with them.

"Alright, you should go back to rest first, and I'll follow up on the progress on the technical side."

"Boss, the nails are strong and they take turns off, and today I am on duty with Meimei." I haven't followed Ying Mingyu to investigate the case for more than ten days, and Bao Zhan still misses it, and said happily.

"Boss, I'm okay, I can get through it tonight." Ding Yuan raised his hand to make a statement.

Da Zhuang really can't do it, he should take a break in the afternoon, in order to wait until he meets Ying Mingyu, he was stunned in the bureau for a while just now.

"No, you two go back to rest, it's not a critical time yet, maybe tomorrow you will come just in time to arrest someone."

Ying Mingyu believes that the people in the technical department will not be helpless, even if it takes a little more time, they can always find the person they should find.

Ding Yuan said goodbye to Da Zhuang, and Bao Zhanxing rushed to follow Ying Mingyu to the technical department to ask about the situation.

"Captain Ying, don't worry, we have invited experts, hacker experts from technology companies, others have already asked us, and we have to work overtime all night to find out this person as soon as possible."

Ying Mingyu looked at it a little, and saw that it was a very young boy, who looked like he was only eighteen or nineteen years old. He didn't have much suspicion, this computer technology thing seemed to be much more powerful when he was a year younger. Including in the use of electronic devices, he can't even catch up with Lu Qianqian, and he has never used video calls or anything. Just watch a forum and watch the video.

"Ask around, go buy some hot drinks." In the past, Ying Mingyu often came to the technical department to trouble them, but it was never a matter of letting others work overtime like this, especially the people from outside.

He went back and took some snacks that Lu Qianqian made for him, and asked Bao Zhan to send them to the person on duty in the technical department and the foreign expert.

Captain He came to him when he was free, Captain Wang is on rest today, they still have more time, and they can talk slowly.

Captain He has more information than theirs, and the women who have a relationship with Fang Qingquan, in addition to female civil servants, also find out a lot of people in the Fengyue Field. These people have an intersection with Cheng Chengyuan, after all, in the same Hanzhong City, the fields and girls who can play are all those, and there will always be overlaps.

It's a pity that they haven't found the forced girl, nor have they found a woman similar to the one in the surveillance, let alone any clear evidence of buying a murderer. I found two or three suspicious bank transactions, and after verification, I found something for the Anti-Corruption Bureau, but it had nothing to do with the buyer.

Ying Mingyu looked at the investigation materials on his side, but he didn't find any key figures, and he couldn't even find a suspicious direction.

"I think this 'pure Lily' on your side is very suspicious, your guess is very likely, you might as well follow this path and check it for two more days." Captain He repeatedly read the information on Ying Mingyu's side, and opened his mouth to change the direction.

"Don't embarrass you, no matter what the boss says, I will continue to investigate, at least find this person first."

"Captain Ying, to tell you the truth, I admire your methods of investigating the case. As for you, it's not really a thing. ”

Bao Zhan was happy when he heard this, he was really not the captain before, and he dared to speak like this in person, so he obeyed him.

"I apologize to you, tell me, what do you want to do?" The captain should admit his mistake.

Captain He coughed and hung his throat before saying, "Actually, I've been feeling unwell recently, maybe I can't hold it up tonight, and I want to take a few days off to rest?" ”

Ying Mingyu was a little surprised, this kind of bad habit that usually looks like a lazy escape, I can't imagine that I can use it to do this kind of thing.

"Captain Ying, you really have to learn a little more when it comes to being a man. Your Lu girl doesn't help you out, you're really annoying. ”

Ying Mingyu was impressed by him, this person didn't say a word to him on weekdays, but this time because of this case and the late-night cover-up, he also saw a lot of true faces.

"Wait, what did Lu Qianqian do?"

"Think for yourself." Captain He said and left.

Ying Mingyu couldn't think of it for a while, and when he looked down, he found Bao Zhan holding his stomach and bending over with a muffled laugh.
