I only heard Fu Liangtao reply: "I think it's because Xu Ningzhi, Liu Zijun and Cheng Qiao also have excessive attention to Xu Jingjia."

Pang Jitong still didn't understand, and questioned: "Based on the calls and messages you received, haven't you already analyzed that the information was sent by the perpetrator to specific people in a targeted manner?

It's like to Li Bingde's wife, Luo Xiaowen."

Fu Liangtao lowered his head and flipped the folder in his hand to the electronic device analysis reports of Xu Ningzhi, Liu Zijun, Cheng Qiao, Zhou Muqing and Li Bingde, and listed the list of documents related to Xu Jingjia, before putting the folder in front of Pang Jitong, and then said, "Let me ask you, what is the common recording file format for mobile phones?"

Pang Jitong's eyes then fell on the various audio files on the document list, and he said: "If you use the recording function that comes with the system, the M4a format is mostly seen in crazy models, and the models that use the Enjoy platform such as Xiaohao are 3gp, AMR, and WAV. Of course, you can install other apps to choose the more common file format."

As soon as the words fell, Luo Mengning, who was sitting opposite, said, "In this way, the audio files about Xu Jingjia in the electronic devices of the five of them are all mp3 files, which can be opened without a specific application.

Since no original recordings have been found in the list of restored archives, the possibility of them converting the format after recording the archives can be ruled out. At the same time, there is no trace of other recording apps installed on their phones."

Hearing Luo Mengning's words, Fu Liangtao knew that she had understood what he was referring to, so he glanced at Luo Mengning with a smile, and then said, "The format of these audio files shows that they are different from me, and the audio about Xu Jingjia in their mobile phones is not recorded from calls and messages.

During the interrogation of Xu Ningzhi and the others, each of them basically admitted that the files about Xu Jingjia in the mobile phone were deleted by themselves, which means that they already knew about the existence of these files, and they did not put these files in after someone else hacked into their mobile phones."

This explanation made Pang Jitong vaguely understand something, but he always felt that he didn't understand enough and couldn't say why. As a result, Pang Jitong's eyebrows furrowed tightly. Even so, he didn't ask the question in his heart as he did just now.

Fu Liangtao was thinking about whether to digest it with Pang Jitong first, and Luo Mengning, who was sitting opposite, asked, "Ah Tao, what do you mean?"

Fu Liangtao sighed and continued, "When we 'invited' them to come back to help, we mentioned to them that we suspected that they were related to two cases of online harassment. For a long time, when we visited them, we only mentioned Zhou Muqing's matter, and never revealed Li Bingde's matter to them.

And just like that, something interesting happened. During the questioning, they automatically substituted Hui Ching-jia as the victim in another case. Moreover, they were not surprised at all when I mentioned that Xu Jingjia was harassed, and it was clear that they had known about it for a long time.

The three of them have all emphasized that Zhou Muqing's matter has nothing to do with them......

After listening to this, Luo Mengning suddenly realized: "I understand, in fact, while emphasizing this point, they are also unconsciously emphasizing that only Zhou Muqing's matter has nothing to do with them."

In the case analysis meeting, Luo Mengning rarely took the initiative in content other than mobile phone analysis. Fu Liangtao glanced at Pang Jitong without a trace, since Luo Mengning joined the discussion just now, Pang Jitong has not opened his mouth.

After thinking about it, Fu Liangtao nodded at Luo Mengning and said with a smile, "That's right. Once they talk about Xu Jingjia's harassment, they refuse to share any information, and even in the absence of communication, they are sure that no one else will do so.

I'm sure it's not due to trust. Liu Zijun's actions proved that in order to go home, she was willing to exchange any message for Ming, and she did not hesitate to sacrifice the other two. But in such a situation, Liu Zijun still chose to keep silent. This shows that she thinks that if she gives us this information, she will not be pleased.

Moreover, they also said that "harassing Xu Jingjia cannot be regarded as their doing." This is even more awkward, if the understanding of this is replaced by a question of right and wrong, then is the harassment of Xu Jingjia related to them or not?

Therefore, I speculate that the files about Xu Jingjia restored in the mobile phones of the three of them were obtained by them through specific channels. I believe that Li Bingde and Zhou Muqing's situation is similar to theirs."

recalled that in the previous case analysis, Fu Liangtao had mentioned that Li Bingde and Zhou Muqing both had unusual attention to Xu Jingjia, and Pang Jitong thought that Xu Ningzhi and others were the same, and finally couldn't help asking, "Then aren't they the perpetrators?"

"No, they don't have enough computer skills." Fu Liangtao affirmatively rejected Pang Jitong's conjecture, and then began to play the relevant video clips of the interrogation, while explaining: "First of all, I will talk about Xu Ningzhi and Liu Zijun, after mentioning the deletion of the files to them during the interrogation, both of them directly suspected that the other party had revealed the information to us, and never thought that we had obtained evidence from the mobile phone mirror by repairing the files. They then revealed more information to us because they were unsure.

And Cheng Qiao was similar, when I mentioned that she had deleted all the files about Xu Jingjia on the fourth day after Zhou Muqing's death, her original confidence also disappeared, and she unconsciously relaxed her lips and opened her eyes, apparently surprised her by what I said. She had no idea that we would know this.

Their reaction was not disguised, which showed that they did not know that mobile phones were different from computers, and that mobile phones might still retain files that had been deleted for some time. And from the perspective of the skill of the perpetrator, this should be just basic common sense for the perpetrator."

Pang Jitong nodded and said in a deep voice, "Cheng Qiao said that they don't want to be the next Zhou Muqing. It's no wonder they react this way when we ask for a mobile phone to be detected. Although it was rejected, it was still agreed. It turned out that they didn't have the ability to protect themselves." After a pause, Pang Jitong asked again, "Sir Tao, since it has been determined that they had collected Xu Jingjia's information, why did you let them go just now?"

Fu Liangtao had expected Pang Jitong to ask this question, so he said, "Do you remember the last time I studied the case, I told you about the example of the invasion case of Puyu Company?"

Pang Jitong instantly came back to his senses and asked, "Is it because it is impossible to prove that anyone has benefited or suffered losses as a result?" So, they're not breaking the law?"
