Chengzhou Police Department, special dispatch team office.

late at night.

Zhao Yu can't remember clearly. This is the time since he became a criminal policeman to stay up late to analyze the case. Although the location has changed and even been abroad, the whiteboard in front of him is always so similar and so familiar.

To be honest, today, especially after returning from South Korea, Zhao Yu is exhausted and does not feel as energetic as before.

Moreover, I don’t know if it’s because of the lack of adaptation to the local environment or some psychological effects, but my tinnitus, which had already recovered smoothly, also started to suffer.

Maybe... I should really have a good rest, right?

In fact, Zhao Yu is still very familiar with his condition. Although there is a major case now, he has not really survived the night since he came to Chengzhou for more than a week, nor has he felt too much pressure.

After all, he has solved too many unsolved cases. For this murder diary case, from the beginning, he really felt that he didn't like it too much.

In Zhao Yu's opinion, this case happened on campus after all. Although it was an old case that happened more than 20 years ago, there were obviously more clues to be found in this case than the unsolved cases he had previously investigated.

Therefore, he always believed that solving this case should be a natural thing as before!

Moreover, there are more and more clues now, especially since they have collected crucial suspect samples from the corpse. As long as the suspect can be found, they can compare them.

Now, they have identified one of the victims, so Zhao Yu feels more and more that the day to unravel the truth of the murder diary should not be far away!

Therefore, today, Zhao Yu, despite Miao Ying's opposition, planned to sort out the case again overnight.

Just like the feeling many times before, he had already vaguely felt that the truth might have appeared in his vision, but he had not yet captured it.

"Team Leader Zhao," at this time, Captain Mou Yongen was with Zhao Yu and reported to Zhao Yuhui, "We have found the police officer in charge of Xin Lili's disappearance case back then.

"But... the two policemen have retired. You know that at that time, they would receive similar reports every day, and they had no impression of them..."

"Well..." Zhao Yu nodded. In his opinion, although the victim's information is important, it does not have much effect on solving the case.

Because this case has a very clear factor in serial murder, the murderer chose the victim in a hidden environment.

In addition to the victim's special identity, it will inevitably be very difficult if you want to investigate the case through the victim's interpersonal relationship.

Previously, Captain Mou had sent a large number of police officers to find relevant personnel according to the names and information provided by Xiaoqiang.

However, so far, no useful information has been sent back. Although the police found several people who knew Xin Lili or Sang Xiaoxiao, they all said that they were not familiar with Sang Xiaoxiao!

In most cases of murder and corpse throwing, generally as long as the body can be confirmed, the suspect can be found. The murderer must be a person who has a hatred or dispute with the deceased.

However, the most difficult thing about the murder diary is that the murderer may have no other relationship with the deceased, and was chosen by the murderer based on certain characteristics.

It means that this case is not only an old unsolved case, but also a serial murder case that was chosen immediately!

Therefore, Zhao Yu believes that if you want to solve this case, you have to work hard on Liu Wei's manuscript, the residents in Zhizhen Building, and the school.

At this moment, Zhao Yu stood in front of the whiteboard, refiltering the clues he has at present, trying to find a way out.

"Team leader," Zeng Ke, who was checking the video of the class reunion, reported a situation to Zhao Yu. "Liu's only classmate claimed at the dinner table that Lao Song, the guard of Zhizhen Building, once asked his nephew to take the class for two months..."

"Oh?" Zhao Yu snapped his fingers and said only one word, "Check!"

"I understand!" Zeng Ke nodded, and then said, "Also, a teacher said that one summer, because of the maintenance of the main teaching building of the school, a temporary passage opened on the west side of the school.

"That passage happened to pass by Zhizhen Tower. Could the murderer have led the deceased through that passage?"

"Remember to contact this teacher tomorrow," Zhao Yu reminded, "and ask for details again! After all, the construction is a short period of time, but the murder case has lasted for several years!"

"Okay." Zeng Ke nodded and continued to view the video.

"Boss, I have someone here," Ran Tao said to Zhao Yu again, "He has read Liu Wei's manuscript. It was a blue notebook, and he also said that Liu Wei's writing was a bit sloppy and could not read it at all..."

"Such a clue," Zhao Yu waved his hand and said, "Just write it in the notebook first, don't report it to me!"

"Oh..." Ran Tao quickly shut up and continued to check.

At this moment, Zhao Yu had a general idea in his mind. He still knew this kind of person better about the victim Sang Xiaoxiao, No. 5.

After all, I often deal with women of this special profession in my previous life.

Zhao Yu believes that according to Xiaoqiang and others' description, Sang Xiaoxiao should be similar to the senior practitioners of Xihai Nightclub, and they are the kind who are free to work.

Coupled with her temperament, appearance, etc., Zhao Yu could judge that the price of Sang Xiaoxiao would definitely be expensive.

Recalling the embarrassing incident with Yang Hong when he had just traveled through time, he encountered the embarrassing incident of "true love is priceless, three thousand overnight".

Therefore, Zhao Yu judged that a high-end woman like Sang Xiaoxiao would not accept it even if the other party gave a lot of money and went to the school dormitory with him!

They usually go to big star hotels.

In addition, Zhao Yu understands the inside story. If Sang Xiaoxiao launches a high-end place like Xihai Hotel, he will generally only agree to regular customers.

If the young guest is in charge, the hotel will take measures, for fear that the young guest is undercover or something.

Therefore, if the murderer asked Sang Xiaoxiao out through formal channels, he would inevitably be known by the hotel.

Therefore, based on this judgment, Zhao Yu believes that Sang Xiaoxiao must have been forcibly kidnapped to the school by the murderer.

If we judge according to this idea, the murderer's economic conditions at that time must be very average.

Also, through the judgment of the corpse, since the appearance and height of the five victims are slightly the same, Zhao Yu has reason to suspect that there are certain standards for the murderer to choose the victim!

You should know that in Liu Wei's manuscript, the victims are all college students from other schools.

However, the real dead are all special practitioners.

So...is there something hidden in this?

Perhaps, Liu's murder diary was just a trigger. This mysterious murderer had long had the idea of ​​killing because of psychological distortion or some kind of blow!?

He just used Liu Yishi's manuscript to fulfill his long-cherished wish to kill?
Chapter completed!
