Suning was still pondering, and Lao Zhao over there lit a cigarette and said:

"We have asked international professionals to test the handwriting in the note, and compared it with the handwriting of the deceased before his death, there is no trace of falsification, that is, the content in the record is from the hands of the deceased. Moreover, there are no other fingerprints in the book except for the deceased, so there is no doubt about the real surname of this book. ”

After Lao Zhao finished speaking, Forensic Doctor Wang pushed his glasses and took over the topic.

"We have interrogated the deceased's roommates and parents in detail, and proved that this book was indeed a common item used by the deceased during his lifetime, and that the deceased cherished and valued this book very much during his lifetime, and often carried it with him, and according to the deceased's roommate, on the day of the incident, the deceased took this book with him. Therefore, we judge that there are two possibilities for the purpose of the murderer to leave the notebook: first, to provoke our police; Second, the confession of the deceased. ”

Xia Zuowei took a sip of strong tea, swept his gaze over the photos on the wall, and said:

"In fact, these two possibilities are not contradictory, people have many faces, after the murderer frantically and brutally kills the deceased, the distorted psychology is released, he will become extremely fragile and kind, leaving a notebook, in order to get the forgiveness of the soul of the deceased, and at the same time, I also hope that we can catch him, so that he can introduce his contradictory and sinful life."

Suning nodded to show understanding, this is a kind of behavioral psychology, the reason why people are human is contradictory individuals. The murderer brutally killed and dismembered more than 2,000 pieces of the deceased's body, and his psychological quality was undoubtedly high to a limit, and the reason for maintaining such a high psychological quality should be another completely opposite psychological sustenance, in order to achieve some kind of strange mental balance.

For example, if a person does something bad, he will go to church to confess, and after repentance, he will be liberated and reach a certain balance, and then continue to do bad things.

In the memory of future instructors, this is a relatively common form of criminal psychology.

By analogy, in this case, the murderer is likely to be this kind of person, brutally killing the deceased, and at the same time longing for the forgiveness of the deceased's soul. And, most likely, he realized this and didn't like his current life, so he desperately wanted to end it all. But as a human being, it is instinct to seek good fortune and avoid evil, and he wants but is afraid of the end, so the only way he can think of without going against his instinctive will is to let the police handle it all, in a way similar to provocation.

But unfortunately, the police have not been able to do anything.

Suning's eyes narrowed slightly, a high-IQ criminal, a criminal who longed for the end, how could he not leave clues in the notebook?

He suddenly asked Lao Zhao.

"Did the deceased have the habit of writing a diary every day?"

Lao Zhao was stunned for a moment, holding a cigarette between his index and middle fingers, nodded and said:

"Yes, I went to their house to find out that the deceased had the habit of writing notes every day since elementary school, and never stopped."

Suning's eyes flashed, and he suddenly asked a clueless question.

"What year is 2000?"

The faces of the three people present changed suddenly, Xia Zuowei's hot tea didn't react to his shoes, the cigarette that Lao Zhao handed to his mouth burned so much that he forgot to spit it out, and the pen that Wang forensic doctor made a record poked into the notebook.

Seeing that no one answered, Suning looked around, rubbed his eyebrows, and said softly:

"I remember that 2000 is a leap year, and usually there are 366 days in leap years, and the extra day is February 29, but if what Lao Zhao said is true, the deceased has the habit of writing notes every day, why is there no such day as February 29? Did you forget to write it, or did someone take it away? ”

The three of you here, look at me, I look at you, look at each other, amazing!

This kid has only been watching for a long time, and he has found out the way, and he has spent countless manpower and material resources to dispatch outstanding cadres and police officers and experts from the whole city and even the province to study the case together. With such a huge scale, it took more than half a year and a chance to discover this extremely subtle loophole.

Now this kid, as soon as he came, found that it was too against the sky!

Lao Zhao and Wang Forensic Medicine were still a little contemptuous at first, thinking that Suning was too young, and at first glance he was a college student, what could college students do, but they didn't think about Suning's few words, and pointed out the key to the problem.

Xia Zuowei cleared his throat and said bluntly:

"We have studied this point you raised, and it is indeed true, on February 29, this page was missing, and we organized multiple police forces to conduct follow-up visits and investigations in the deceased's home and bedroom, and did not let go of any corner, but unfortunately, we did not find any clues on this page of February 29."

Suning nodded, pinching her chin, her gaze back and forth between the photos on the wall.

"If I'm not mistaken, in fact, the lost February 29 note has no value, even if it is really found, it is just a worthless thing, the murderer cannot know the deceased in February, you were substituted by the murderer into a misunderstanding."

All three listened attentively and did not make any moves.

Suning's brows furrowed slightly, his eyes fixed on one point, rubbed his eyebrows, and continued:

"The reason why the murderer revealed this is not only to divert the attention of the police, but also to tell us something."

Tell us something? What is it? The three of them listened attentively, and Lao Zhao was the most anxious, so he shouted loudly at the moment.

"Little comrade, you are so straightforward, what does this bastard want to tell us?"

Suning shook his head and said:

"It's still uncertain, by the way," Suning pointed to the cover of the notebook in the photo and said, "You planted the notebook, do you still sell it now?" If there is a sale, can you bring some over? ”

Suning paused, looked at Xia Zuowei, and then said:

"If it's convenient, I'd like to see the deceased's notebook."

The three people here didn't say anything for a while, the problem in front is easy to solve, although in the past ten years, this kind of notebook has been discontinued, but there is the manufacturer's contact information behind the notebook, and they will always have inventory there.

But the second question raised by Suning, it is more troublesome, 107 is a big case that shocked the whole country, as the only evidence of strong clues, this notebook has long been stored in the most secret place of the Provincial Public Security Department, if you want to take it out, you must go through layers of declaration and approval, if you can find a little clue It's okay, in case you don't find it, the leaders above think you are playing tricks on him, and you are angry, and no one can afford it.

Suning can't help it, he has a bold guess, but he must see the most primitive book to be sure.

In the end, Xia Zuowei gritted his teeth and agreed.

Then the three acted separately, and the entire public security bureau operated efficiently. Half an hour later, Xia Zuowei led Suning to the Provincial Public Security Department, and at the same time, 10 copies of the same batch number as the deceased's notebook were also on the way to the Provincial Public Security Department.

Everything is about to be revealed......
