Fueled by the media, the families of the victims, who did not make any more trouble, began to enter the police academy again, they were on the victim's side, and the office of the task force was set up inside the police academy, and the school could not prevent them from entering the police academy. They did not dare to blatantly go to the office to annoy the criminal police and the leaders of the police academy, but they sat in the police academy all day long in mourning clothes.

At night, they would also burn paper money in the police academy, which was fine during the day, but late at night, their actions frightened many female students who had finished their training. The leadership of the police academy wanted to let them leave on the grounds of hindering teaching, but they were afraid of being gossiped about by the media, so they had to endure it for the time being and asked all groups of students not to come into contact with them.

The leaders of the police academy have complained more than once, saying that although they can understand the sad feelings of their relatives, their excessive behavior has hindered the progress of the case, and these relatives are not aware of it at all. At first, there were many students who sympathized with the relatives of the victims, but slowly, everyone was also angry, and some students who couldn't see it came forward to reason with them.

But where are the relatives of the victims willing to listen, and in the end, there are basically no students to deal with them. Only the relatives of the fourth girl were more sensible, the body was parked in the morgue, they often came to see their daughter and asked about the progress of the case, Wen Ning did not tell the relatives that the fourth girl was suspected of committing suicide in fear of crime, so as not to cause another incident.

Wen Ning secretly had the students who had access to the identification center and the four deceased people investigated, but found nothing. Wen Ning asked the management of the appraisal center that students who need to borrow the equipment of the appraisal center academically must register with their real names, and the management of the appraisal center is quite strict.

However, when students take professional courses such as autopsy and trace identification, the lecturer will send out a lot of special identification bags, which are not valuable things, so the identification center does not strictly manage them. If the assumption that the murderer was an insider of the police academy is correct, the murderer must have taken advantage of this loophole to take the special identification bag away from the identification center.

The bag can be folded up and hidden on the body, so the management did not pay attention to whether anyone did it some time ago.

On the other hand, because of the special situation, the police even monitored the public card phones in the dormitory building of the police academy in accordance with legal procedures. Because of the special nature of the police academy, the student group is not allowed to use mobile phones during the police academy students, and not all students use mobile phones, so the student group basically relies on the telephone on each floor of the dormitory building.

Every evening, there is a long line in front of the payphone, and students call in turn. But despite such technical investigations, the police were unable to find the suspicious calls. According to Wen Ning, students basically call their families, but also to their partners and friends.

For two days, Wen Ning began to wonder if my guess was correct. He also sent people to investigate the suspected person who sold ghost books, but this was tantamount to looking for a needle in a haystack. However, Wen Ning was not discouraged, and he thought of a good way to investigate the suspect.

Wen Ning named the mission a wide net, and it was the day when the police academy students could go out of the police academy on the weekend, Wen Ning sent a large number of police officers to disguise themselves as ordinary people, and when they saw people traveling alone or a man and a woman, they followed to investigate. Not all police academy students will leave school, Wen Ning thinks that there is only one way to find out the truth now.

Although it is speculated according to common sense that after the murderer killed someone, in order not to arouse suspicion, he would not do any more acts that might expose the facts, Wen Ning believes that the murderer inside the police academy must be very panicked now and needs to communicate with the accomplices, because the police have set up a special task force in the police academy. He said that whether one of the murderers was a member of the police academy or both, they would definitely not communicate within the school for a while, and the days when they could go out were an excellent opportunity for them to communicate.

Wen Ning said that he could only try, he wanted to cast a wide net, and no one would be spared, if he couldn't find out anything this time, he would wait for the next time the police academy students left the police academy to cast a wide net again. By the time I got to the office, he had already sent everyone out.

Wen Ning didn't want to stay in the office any longer, so I thought about it and went out with him.

The number of students in the police academy is not large, Wen Ning told me when he took me out of the police academy that almost half of the people will go out of the police academy to buy things, and there are fewer people in the school, and the murderer may also be exposed, so he also arranged for someone to continue the investigation in the school. Most of the people who go out of the police academy are in groups, and according to the current information from plainclothes police, dozens of students are going out alone, and there are several pairs of men and women who go out, but very few.

Wen Ning told them to keep up with them, and report any strange findings immediately. Wen Ning and I found a remote place to sit under the tree outside the police academy. Wen Ning laughed at himself, saying that he seemed a bit stupid to do this, relying on crowd tactics to cast a big net, if he didn't catch a big fish, it was estimated that he would be scolded by Xu Tong.

As far as I know, Xu Tong's temper is not very good, and he is a relatively dignified and serious person in the police world.

The weather was hot and muggy, and there was still more than a month before the end of the scorching heat, so Wen Ning gave me a cigarette and lit it for me. Where we stared at the school gate, there were many criminal police officers around the police academy who had not yet set off, and their camouflage skills were very good, and they were not too close to the gate of the police academy.

Whenever a suspicious target appears, they follow a person. Slowly it was three o'clock in the evening, and the police academy students had to return before five o'clock in the afternoon, and by this time, many students had already returned. At this time, only a few students went out sporadically, all in groups.

They should all be students who are going to the neighborhood to buy necessities. Wen Ning extinguished the last cigarette, and he stepped on it hard, preparing for the police to evacuate. Everyone spent a whole day in the sun, and they almost couldn't stand it. I thought about it and asked Wen Ning to hold on a little longer.

The murderer is in the police academy system, and his vigilance is not small, everyone has endured it for a day, and if the investigation is relaxed because of the last period, it is likely to miss something. Wen Ning asked me what to do, I thought about it, and asked Wen Ning to inform all the plainclothes police officers to evacuate, there should not be so many people here in the evening.

Wen Ning nodded, dialed a phone call, and then, those plainclothes policemen evacuated farther away one after another. I looked at my watch, and at ten o'clock in the evening, Wen Ning sat down patiently again, and in the next twenty minutes, a few more students left the police academy in groups, but they all got into the supermarket on the street opposite the police academy.

At half past three in the afternoon, Wen Ning and I finally waited for a girl in a dress to come out of the school gate, and Wen Ning stood up excitedly. He stared at the girl who was going out, dialed the phone, and he asked people to continue to observe the school gate, and found a person, and the three of us followed the girl.

When the girl went out, she didn't even turn her head around, and I always felt that she was pretending to be too deliberate, so Wen Ning and I would follow in person. The girl didn't look around, but walked briskly forward, and we followed the girl from a distance. The girl kept raising her hand to look at her watch, showing great anxiety.

We followed the girl for about ten minutes before she walked into a small alley, which was a dead end, and the entrance of the alley was facing a street, and there was a small tree on the opposite side of the street. To avoid being discovered, we hid behind a tree across the street. Everyone's eyesight was good, but because of the distance, we could only barely see two people in the alley.

One man and one woman, the man wears a shirt and short hair. The man had his back to us and we had no way of seeing his face. He was talking to the girl at the police academy, and it seemed that there was an argument, and the girl gave the boy a slap, and the boy didn't fight back. Just as the boy was about to turn his head, a car blocked in front of us.

Wen Ning and I were stunned for a moment, and immediately walked to the side, and when we looked into the alley, the man had already called a taxi and left, and when he got into the car, we still couldn't see his face clearly. The taxi drove so fast that it was out of sight almost instantly, and we didn't even write down the license plate number.

The girl also came out of the alley, she was crying, and she walked back and forth step by step. Wen Ning was about to go up and grab the girl.

"Wait, that's not right." I stopped Wen Ning.

I have seen the car in front of us, it is You Lu's, and sure enough, the window was rolled down, and we saw You Lu's smiling face.
