Expanding the scope of the search, Xu Shu also called up the monitoring around the school to check.

No suspicious person was found at all.

"Did you still use stealth to get in?"

Jiang Qingrui teased the lively atmosphere, put down the corners of her mouth after speaking, and got up and walked around irritably.

It's been a long time since I've experienced this kind of mood, the murderer is perfectly hidden, blending into the night, and there is no trace in sight.

"kk, you check this person's information."

kk came back at this time, and jiang qingrui took kang yuancai's computer to her, pointed to the online dating partner and said.

The gender of this person is now an issue, and after Jiang Qingrui and Xu Shu discussed, there is a high probability that this person is the murderer behind the scenes.

He disguised himself as a girl on the Internet and deliberately approached Kang Yuancai, not knowing if he had discovered the truth now.

kk's expression became more and more solemn, and he tried to find the other party's IP, but all failed.

The position of the other party is elusive, and even the approximate range cannot be determined.

"Is this person a suspect?"

kk asked as he fast-tracked.

"Yes."

Jiang Qingrui knew that she was in trouble again when she looked at KK's expression, so she didn't bother too much, and turned around and returned to her workstation.

"He's very good at computers."

KK rarely gives such a high rating, and the last time he praised him was the people in the shelter.

Xu Shu has made no progress on his side, and now he can only put his hope on KK.

But the other party is too cunning, keeps changing addresses, and even sets up attack programs, which is impossible to prevent against kk.

The confrontation between the two reached a stalemate, and no clues could be found for a while.

So far, all possible directions in the field of seeing have stalled.

Xu Shu never dared to break the situation from the other side.

Since the murderer is targeting the students of the school, he must have an understanding of this school, and it can even be said that he is quite familiar with it, so he will enter the grove smoothly.

He also wandered around the school's campus network for a long time, this is not pure patience, at least in his heart, there is something supporting the murderer to collect this information.

Xu Shu called Jiang Wu, and now KK is busy and can't distract her.

"One and a half, see which people in it have enemies."

Xu Shu handed Jiang Wu a list of people, all of whom were high-level officials of this school.

He also has a hypothesis that the murderer made a feud with the school's leaders, and tried to bring down the school by killing people to vent his anger, so that they would be ruined, and the school's reputation would decline day by day, and the goal of revenge would be achieved.

This school is just an ordinary university, not ranked in the top class, and it is mediocre in every way.

After Xu Shu read the information, he ruled out the malicious competition of his peers.

Nowadays, the means of business warfare are endless, and the slightest carelessness will capsize in the gutter.

Xu Shu and Jiang Wu stayed up all night to investigate in turn, and there were no clues.

"I even found out that he has a junior, why didn't this enemy appear."

Jiang Wu looked at the sky that was gradually brightening, and sat down in his chair sluggishly.

Such an aimless search is not a good solution, but so far there is no effective measure.

"And what ordinary person has an enemy?"

Jiang Wu sighed, and suddenly resented the murderer, "What kind of person is you killing in a good way, causing chaos to the society and the police!" ”

The man was full of energy and chattered and complained.

Xu Shu checked the last piece of information, "You go and rest." ”

Jiang Wu waited for this sentence, and after saying goodbye, he left quickly, and the direction seemed to be to go to the cafeteria to catch the first pot of breakfast.

Xu Shu not only conducted an investigation privately, but also put this hypothesis on the surface.

"Impossible!"

The principal swore that "I have screened each of them, and there will never be such a situation as you said." ”

The leaders followed behind the principal.

"Everyone has been together for so long, we all know each other, and we will know each other if there is a hint of trouble, and we don't need to hide it from you."

When it comes to privacy, someone doesn't have a good complexion, and Xu Shu recognizes him as the one with a mistress.

No one wants their privacy to be suddenly put on the table in broad daylight, and a few people hold opposing opinions and unanimously believe that there is no problem.

If Jiang Qingrui was present, he would definitely tell him secretly afterwards, and he thought he was a comrade-in-arms who was a friend of life and death.

Just when the leaders were defending themselves, Xu Shu noticed that there was a person standing in the corner. From the beginning to the present, he has never said a word, consciously reducing his sense of existence.

Of course, he won't let go of this person who didn't notice on the surface and followed the words of the leaders, "Don't get excited, the police are just conducting a routine investigation, and it's not that I don't believe what you mean." ”

There was a loud fart, and everyone's faces softened.

After everyone dispersed, Xu Shu found this person for the first time, he looked weird, and at first glance he was hiding something.

"I knew you would find out sooner or later......"

The man looked around vigilantly, but there were no acquaintances, and pulled Xu Shuo to a hidden corner.

"I know what you're trying to ask."

The man took a few deep breaths, "I've been hiding it in my heart for a long time, and now I finally have the opportunity to say it." ”

The man suddenly pulled the time back to five years ago.

"There was a girl at school who hanged herself."

The location of the suicide is the same as Kang Yuancai, both of which are small forests.

The girl is excellent in character and learning, sincere and friendly, and has a very friendly relationship with the teacher, and no one can figure out why she hanged herself.

Others have boldly hypothesized that the girl was actually killed or subjected to an indelible psychological shadow.

But no matter what the situation was, it was not confirmed, and the school immediately suppressed the matter.

The police had only come once, and there was no news after the body was taken.

The teachers and students of the whole school urgently convened a general meeting to rot this matter in their stomachs and not allow it to be spread outside. The reason is for the reputation of the school and to avoid causing unnecessary panic.

In the brainwashing of the teacher, the students thought it was an accident, and after a long time, some people gradually forgot about it.

"The person who suppressed this matter was the previous principal."

The man finally said these words, and the boulder that had been blocking his chest finally fell.

"Why is he hiding it?"

"I don't know." The man was telling the truth, and according to his understanding, the girl had nothing to do with the principal, "It may affect the admissions." ”

Since he is a principal, there is a reasonable explanation for doing these things.

However, the picture of the seal was too obvious at that time, and the man took this matter to heart.

The students of five years ago graduated early, and no one, except for the old teachers, remembers the suicide of the girl.

The man still doesn't know the results of the police investigation, and the girl is her student, which is also a knot.
