Chapter 2145 (1/2)

Chengzhou police station, in the office of the task force.

Late at night.

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

To tell the truth, up to now, especially after returning from South Korea, Zhao Yu is tired and does not feel as energetic as before.

Moreover, I don't know whether it is acclimatized or what psychological effect. Tinnitus, which has recovered smoothly, has also been committed.

Maybe... Should we really have a good rest?

In fact, Zhao Yu knows his state very well. Although there is a big case now, he hasn't really stayed up overnight or felt too much pressure since he came to Chengzhou for more than a week.

After all, he has solved too many outstanding old cases. For this murder diary case, from the beginning, he really didn't pay much attention to it.

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

Therefore, he always believed that the detection of this case should be as natural as before!

Moreover, there are more and more clues now. In particular, they have collected crucial suspect samples from the bones. As long as they can find the suspect, they can compare them.

Now, they have identified one of the victims. Therefore, Zhao Yuyue feels that the day to dissociate the truth of the murder diary should not be far away!

Therefore, regardless of Miao Ying's objection, Zhao Yu plans to sort out the case again overnight.

Like many times before, he has vaguely felt that the truth may have appeared in his vision, but it has not been captured by him.

”Leader Zhao,” at this time, Captain Mou Yongen accompanied Zhao Yu and reported to Zhao Yuhui, ”we have found the police responsible for Xin Lili's disappearance.

”However... The two policemen have retired. You know, at that time, they received similar reports every day. They have no impression...”

”Well...” Zhao Yu nodded. In his opinion, the victim's information is important, but it has little effect on the detection of the case.

Because this case has very clear serial homicide factors, the killer chose the victim in a hidden environment.

Coupled with the special identity of the victim, it will be very difficult 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 name and information provided by Xiaoqiang.

However, so far, no useful information has been returned. 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 homicide and corpse disposal cases, the suspect can be found as long as the body can be confirmed. The murderer must be a person who has hatred or disputes with the dead.

However, the most difficult thing about the murder diary case is that the murderer probably has no other relationship with the deceased. It was selected by the murderer according to some characteristics.

Equal to, this case is not only an old pending case, but also a random serial homicide!

Therefore, Zhao Yu believes that if you want to solve the case, you have to work hard from Liu's only manuscript, the residents in Zhizhen building, and the school.

At the moment, Zhao Yu is standing in front of the whiteboard, re filtering the clues he currently has, trying to find a way.

”Team leader,” Zeng Ke, who was checking the video of the classmate party at this time, reported a situation to Zhao Yu, ”Liu's only classmate claimed on the wine table that Lao song, the guard of Zhizhen building, once asked his nephew to replace the class for two months...”
