At that time, He Sheng and I were a little puzzled about what Dao Zhiyong meant, but he said: "This person calls himself Wang Jingfu, but I have analyzed some brushstrokes and force on the handwriting, his practice is deliberately disguised, he should have copied some handwriting before, who is Wang Jingfu, or this person does not exist at all...... Either way, this man is also very problematic, and he may be the one behind it. ”

"There should be no absolute basis for using handwriting to determine the gender of the writer, right?" Su Yaxin was skeptical.

Dao Zhiyong did not answer immediately, but opened a betel nut bag, took out the betel nut and chewed it before saying: "Handwriting not only contains the innate physiological characteristics of the writer, but also is affected by acquired learning, which can reflect the writer's writing habits and biological characteristics to a certain extent. The information extracted from the handwriting can be used to determine the gender, age, and habits of the writer and the use of the right or left hand. Men write with smaller margins than women; Men have more handwriting than women, and of course it is possible that the other party has a man's personality, but this is relatively rare.

These handwriting actually seem to be round, smooth, and soft strokes, with many curves and sparse structure, which reflect the writer's flexible, gentle, tolerant, and compassionate character characteristics, he is also a psychiatrist, and his character should be like this, but he saw the pain in Hu Hanfeng's heart and wanted to help her relieve this uncomfortable psychology, so he put forward his own idea, and he was willing to help Hu Hanfeng complete this series of revenge ......"

"So you're also analyzing this from the perspective of psychological profiling?" Su Yaxin asked.

"I'm not as professional as Xia Xiaoling, I'm analyzing it from the aspect of document inspection, in fact, don't underestimate a person's handwriting, this can reflect a person's personality, hobbies, and even work and life, etc."

Dao Zhiyong said with extreme confidence, and I bowed my head: "I haven't questioned you, this time it seems that we have a new direction of investigation, no matter how to find out this man, or after we break him, Hu Hanfeng will also confess?" ”

"I'm afraid he is even more difficult to deal with than Hu Hanfeng, after all, these plans are all thought of by men."

"But why did he expose the diary, he could take it at any time, or burn it."

"I said, he deliberately showed it to us, so we feel that he is the person behind the scenes, not Hu Hanfeng."

Dao Zhiyong's words triggered my inspiration, and I was still a little puzzled but quickly figured it out: "Monkey, what do you mean is that in fact, the person behind the scenes should be Hu Hanfeng, and the man wants to shift his attention to himself because of her?" ”

"Very good, Ah Kang, this is also the reason why I can think of it, he deliberately showed us the diary."

"This man should like Hu Hanfeng, otherwise he would definitely not have made this step, he had expected that there would definitely be today, or rather, he planned to use this to play psychological warfare with us, don't forget, they are all geniuses in this regard, it is this diary, we can summon this man, we have to visit the research institute, you must know that we don't even know the true identity of this man now!"

Gao Mingqiang is right, I asked him to deal with this matter with He Sheng, and Su Yaxin and I plan to work hard to find more physical evidence, after all, with what we have collected so far, even if it is brought to court, the final result will not be much better.

Su Yaxin and I came to the first place of the crime again, that is, the highway where the car crashed, this is the third time we have come back, this time there are only the two of us, Xia Xiaoling is not there, we have been walking along the road, the previous case line and tire tracks have long been gone, we observed the monitoring probes around us, and we didn't find any clues, but when we looked at a probe seriously, Su Yaxin suddenly said: "How is the direction of this probe consistent with the location of the car accident?" It can't be a coincidence, right? ”

She reminded me of this, I let her stand where she was, and then borrowed a ladder from the nearby traffic control office, and let a traffic policeman come here with me, I dismantled the monitoring in question, checked the internal structure, and didn't find anything wrong, but there were some problems with the control equipment during the inspection, and the place seemed to have been modified, but in terms of equipment, I might as well find Du Yuting to check it.

I received the surveillance into the physical evidence bag, and returned to the Public Security Bureau with Su Yaxin, and after telling Du Yuting some of the situation, she understood what to do, she found Dao Zhiyong, and then the two disassembled the parts of the surveillance together, and when checking the control equipment, Du Yuting really said: "This has been modified!" As we know, the entire monitoring system is divided into four parts - front-end equipment, transmission part, control equipment, and display part.

The control part is the core of the entire monitoring system, which is the clearest embodiment of the scientific and technological level of the system. Usually we have two kinds of control methods, one by one analog control and digital control, analog control is the early control mode, the console is usually composed of a controller or an analog control matrix, the interior was originally just for shooting configuration, but now there is an additional reflector, plus there is a wire connection, I think the role of this monitoring has been completely changed! ”

But what is the purpose of doing so? Could it be that Hu Hanfeng's hypnosis was achieved in this way? Su Yaxin asked.

Xia Xiaoling, who was present at the moment, analyzed: "There is such a possibility, after all, in addition to the sound and smell and the picture of hypnosis, the other is to rely on other ways, no matter which way, the ultimate goal is to make the victim be stimulated, so that they lose control, or are controlled by themselves, but this reflection seems to have little to do with hypnosis." ”

"Do you mean that even if Xing Hongzhen hadn't been hypnotized at that time, he would have lost his way if a light suddenly hit his eyes while driving?" I asked.

"Exactly, isn't this time supposed to have nothing to do with hypnosis? You can investigate whether Wang Jingfu has any accomplishments in hacking. As soon as Xia Xiaoling said this, Du Yuting understood what she was going to do, so she immediately started her hand and tapped on the keyboard to investigate, and soon she said: "I really told you right, Wang Jingfu graduated from the technical college in the past, and it is estimated that the computer is really good, if this is the case, it makes sense, but why did he do it?" Could it be ......?"
