The sea and the book [criminal investigation]

Guo Chen asked Yu Gu and his wife at the breakfast shop, and what they said was exactly the same as Yu Xiaole.

The couple did not post such remarks on the Internet, and it is impossible for others to have access to the computer at home.

"That brat Xiao Le couldn't have done it!" Consultant Yu's wife, Yang Yan, Yang Yan immediately denied it: "How is that possible! Xiao Le was only so old at that time, and he was still playing with mud."

It wasn't the comments sent by their husband and wife, Yu Xiaole is still young, and their husband and wife have never brought outsiders to the house, could it be a supernatural event?

The IP location of the computer login is the most accurate and will not lie, so someone must be lying.

Lu Nanchu and Guo Chen returned to the bureau, exchanged information between the two sides, and sorted out the question and answer recordings of the two sides.

Both Yu Gu and his wife and Yu Xiaole answered without question, and their tone was very positive.

After listening to the two recordings repeatedly, it was Lu Nanchu who finally thought about it and asked, "They all said they wouldn't let outsiders come to the house. But what if it wasn't an outsider? It was their close relatives, such as Yu Gu's brother Yu Shun and sister-in-law He Fang."

When they went to find Yu Shun and He Fang, the two also had evidence to completely rule it out.

That day was a working day, and both of them worked in Yunjia Shopping Mall, and they were full-time throughout July.

After listening to these two recordings a lot, Nan Zhao finally heard some information from Yu Xiaole's recording.

"No, Yu Xiaole is very likely to be lying." Nan Zhao pointed out, "We focus on Yu Gu and Yang Yan's couple as the focus of analysis, and Yu Xiaole, because he is still a child, is a little more relaxed. But children can also lie, but often Because of his age, it was ignored."

She came to the conclusion that Yu Xiaole was lying, precisely because Yu Xiaole's answer was within a second.

After so many days and so many years, how could it be possible to give an answer without thinking at all.

Both Yu Gu and Yang Yan gave their answers after thinking, only Yu Xiaole shook his head and denied without thinking at all.

Is it a habit developed under the strong rules of his mother, which can be realized without thinking when it is engraved in his mind, or is this answer already silently recited in his heart countless times.

"No way? Yu Xiaole is still a 16-year-old child." Shu Manyue was very surprised. If it is confirmed that Yu Xiaole is lying, then it is not far from the truth.

Who is the "Math Terminator"?Why did he go online again after six years to post that post?Contacting his content in the comment area of ​​Pengpeng six years ago, it can almost be concluded that what he said, "Heaven is good for reincarnation, who is spared by heaven" refers to Li Ye who stole Pengpeng's account.

But it's still wrong, at least that comment six years ago couldn't have been made by Yu Xiaole.

From another point of view, the person who posted that comment six years ago must have known that Yu Xiaohua was Peng Peng, so he would have posted this comment.

But it doesn't make sense, if he knew that Yu Xiaohua was Pengpeng, and also knew that the person who controlled the account at that time was a hacker, why didn't he tell the truth for so many years, and instead let Li Ye use Pengpeng's account to do business? A lot of bad things happen?

Nan Zhao guessed: "Unless he can't say it for some purpose, or if he says it, no one will believe it."

Now the only case with some clues is Li Ye's case, but he still fell into a puzzle again.

Yu Xiaole lied, but he couldn't be the one who posted that comment six years ago.

Unless he knows who posted the comment and chooses to lie in order to cover that person.

Everyone in the criminal police brigade is in charge of different sections, and they are all studying the evidence related to this serial case.

New news was detected in the technical room. Both the account "Peng Peng" and the account "Mathematics Terminator" had strange traces of data deletion.

The official social platform provided a batch of data to assist the police in handling the case, showing that the "Mathematics Terminator" account was included in a batch of blocked accounts in July 2016. The reason for the blocking was that many people reported malicious rumors.Up to now, the "Mathematics Terminator" account is still in violation of the ban and has not been unblocked.

But as everyone can see, this account has slipped through the net of the official ban, and came out of the illegal ban without unblocking it.

Following the clues, I found that there was a hacker attack on the social platform system half a year ago, and the "Math Terminator" account was released by the hacker this time.

And in this hacking operation, the hacker also deleted some content of the account of Pengpeng, and the system background cannot restore the data.

No trace of hacker attack was found in the official system before, and the technical room's attempt to recover data was also hindered.

The technical office said that the hackers who attacked the social platform system were very skilled, and even embedded interference data in the system after the attack.

However, the technician said that this nested interference data is also regular and followable. This method is very similar to the tail of the logo that the world's top hackers exchanged ideas with each other and left after the end.

Everyone who heard this statement for the first time was stunned.

Song Shi successfully arrived at Yunying on the morning of the 12th, reported to the Wang Bureau at the Municipal Bureau, and then came to the Criminal Police Brigade to handle the transfer work.

About the Qingtian Psychological Foundation's yin-yang account book and Luo Yuhuai's question, Song Shi was pulled by Lu Nanchu to ask about the details of Yu Xiaohua's case seven years ago. After all, he was the policeman in charge of Yu Xiaohua's case back then.

"The Yu Xiaohua case is also an old case from many years ago. After so many years, I can't remember some details clearly. Why don't you show me the case file from that year first, which can arouse some of my memories." Song Shi took over After drinking the tea that Lu Nanchu handed over, he finished his cup of tea, and then he expressed his opinion.

Lu Nanchu had already brought back all the case analysis of Yu Xiaohua's case from Director Wang, and brought it out to him as he wished: "Think carefully, is there anything unusual about this case back then? This is very important."

After flipping through a few pages of detailed records, Song Shi remembered the same: "The unusual thing is that the investigation of this case went very smoothly at the beginning, from the determination of the death of the deceased to the final agreement on compensation between the school and the parents. The case will be closed if there are too many disputes. Yu Xiaohua's parents are probably a bit patriarchal, and they are very happy when they get the money. But Yu Xiaohua has a cousin who has a good relationship with her sisters. She committed suicide, and suspected that it was a murder case; but all the evidence at the scene at the time proved that she did commit suicide by swallowing sleeping pills. , and broke her brain; but according to her neighbors, the girl didn’t seem to have fallen from upstairs at all, but attempted suicide by jumping off the building.”

There is such a thing!When I checked Yushun before, it was said that Yu Xiaoyu fell from the building in a trance because of the grief of his cousin's death.

"Did the girl's parents not call the police?" Lu Nanchu found it difficult to understand.

"No. It's just that her parents spread the word that the girl slipped and fell, and the police can't do anything about it; the girl doesn't know anything when she wakes up, and that's it." Song Shi sighed.

After meeting Zhao Yitan's wonderful father, Zhao Xu, Lu Nanchu felt that no matter how wonderful his parents were, it wouldn't be too strange.

If Yu Xiaoyu didn't fall from the building by accident, why didn't Yu Shun and his wife call the police and spread fake news outside?

This thing is really too suspicious!The attitude of Yu Shun and his wife is not normal, or the two families of the Yu brothers are not normal.

According to what the teacher of the physics competition class of Yunxi No. [-] Middle School said, Yu Xiaoyu is usually very logical and logical, and he is by no means an unreasonable person.

Could it be that Yu Xiaohua really discovered the suspicion that Yu Xiaohua's suicide was actually murdered, and that's why he acted like this.

Talking to Song Shi about the strange cases that happened in Yunying during this period, Song Shi analyzed: "That is to say, it is very likely to be a copycat murder case? But now there are no suspects, so it is too early to define this I don’t know anything else, but the people who created these cases must have super anti-reconnaissance capabilities, and only by deliberately setting up a murder trap can they escape under the police’s detection.”

If such a group of people really existed, Yun Ying would never have peace in the future.

Just like Lu Nanchu's initial premonition, maybe they were all trapped in a limited box, which caused them to get nothing.

Who will the lying child cover up for?

From the perspective of human nature, none of the people Yu Xiaole covers will be his parents.

A terrible suspicion formed in Lu Nanchu's mind, and he urgently needed to verify this suspicion.

When all possibilities are ruled out, the least likely is the truth.

It's just a trial, even if the guess is proved to be wrong, it's not a big deal.

Lu Nanchu and Guo Chen went to Yu's house again, and this time Yu Gu and Yang Yan were also at home, and they heard that Yu Xiaole was doing homework in the room.

When Yu Gu came to open the door and saw the two of them, he hurriedly asked, "What's the matter with the two police officers?"

"Mr. Yu, I'm sorry to bother you. We came here to ask you a few more questions." Lu Nanchu said.

Yu Gu wanted to pour water for them when they came in, but Guo Chen just said no, and left just asking a few questions; Yang Yan also came out of the kitchen.

Lu Nanchu showed them a photo of Yu Yuyu: "This girl, is your niece Yu Yu?"

"Yes, it's less than." Yu Gu glanced at the photo and nodded.

"I heard from the neighbors that Xiao Yu often comes to your house to play?" Lu Nanchu asked.

"My elder brother and sister-in-law are usually busy with work, and Ayan and I also go out early and return late every day. Xiaole, he listens to Yu the most, and Yu is very obedient and obedient in my house; usually let Yu come to play with Xiaole, Also let their siblings take care of each other at home." Yu Gu didn't know what he meant, so he nodded truthfully.

Guo Chen raised his head inadvertently, and happened to see the study diagonally opposite. The door was not fully viewed, and he could clearly see someone hiding behind the door and carefully eavesdropping.
