Zhao Hao asked Liu Tianqi to find out if there is a camera nearby. If not, the "Sky Eye" system will be enabled. With the current location as the center and 500 meters as the radius, searching for people who meet the characteristics, namely wearing a red jacket and jeans, with a height of between 162-167.

"If this person has anti-reconnaissance awareness, he will probably change his clothes somewhere after giving the lunch box. Now you can watch all the surveillance monitors with a radius of 100 meters, and it is best to capture more of the person's appearance."

Liu Tianqi nodded, took out the computer equipment from the police car, and then went to a nearby side dish to prove his police identity. The owner also cooperated very well and specially made a piece of land on the table for Liu Tianqi to use.

The sky eye system mentioned by Zhao Hao is not only a public camera, but also many civilian cameras. Although civilian cameras require police to go to each other to record videos, recording videos is too simple for Liu Tianqi, and it can be easily hacked into it, so the cameras in the city are equivalent to Liu Tianqi's eyes.

All the meat in the lunch box has been sent to the Criminal Science and Technology Room of the Municipal Public Security Bureau. Now, all Zhao Hao and the others can do is wait for Liu Tianqi to adjust the surveillance and search for the suspect's whereabouts.

Zhao Hao promised the sanitation workers that they would catch the person who delivered their meals in the shortest time. They happened to be working hours soon, and the sanitation workers agreed to leave. But they said that they would wait for a statement from the police here in the evening.

Liu Tianqi took 15 minutes to invade 23 civilian cameras within a radius of 100 meters.

According to surveillance, a young man wearing a red coat carried four large pockets and came to a shade covered by green trees. This is usually a place where sanitation workers rest and eat at lunch.

After he arrived there, he chatted with several sanitation workers for a while, and then distributed the lunch boxes in his pocket to them. After the distribution, the lunch boxes in his pocket should have not been distributed yet. From the monitoring, he could see that there was another pocket that was bulging. Afterwards, he left Liu Qinglu.

According to the direction of the young man leaving, Liu Tianqi also called out the surveillance camera, and finally showed that he had entered a school - Moshui City No. 2 Middle School.

Liu Tianqi asked Brother Zhao to come and see it quickly, and said: "This suspect does not seem to have any anti-reconnaissance awareness at all. After delivering the lunch box, he took the road with many cameras, and he went straight back to the school without detours. I feel that this person should not be the murderer."

Zhao Hao nodded. Indeed, the young man had no concealment from the place where the sanitation workers rested, to delivering lunch boxes and finally leaving, which was not in line with the murderer's criminal psychology.

At this time, Huang Ke called.

"Brother Zhao, I just finished dealing with the little girl who wanted to jump off the building. As soon as I got back to the office, I found that you were gone. Is there a case?"

Zhao Hao asked casually: "How was it handled?"

Huang Ke replied: "The little girl was dumped by her boyfriend and she clamored to jump off the building. She actually wanted to attract his boyfriend's attention and had no intention of jumping. After we called his boyfriend, we stopped jumping for a while. By the way, where are you? I'll come to find you."

Zhao Hao said: "No, no, you can change into casual clothes now and go to Moshui No. 2 Middle School to bring someone back. Try not to attract too many people's attention. If the child is innocent, it will affect his reputation. Who should I find? I will send you a photo after you arrive. Now Tianqi is still cracking the school's monitoring system."

Zhao Hao is still talking to Huang Ke, and Liu Tianqi has begun to crack the school's monitoring system. Only by invading the school's monitoring system can we know which class the person is studying. Otherwise, there are so many students in the entire school, and it is undoubtedly a seabed to find a needle.

As soon as Huang Ke arrived at the school, he received a message from Zhao Hao on his mobile phone.

There is a photo on it. Although the photo is not very clear, you can still see the person's figure, dress and a large pocket in his hand. There is also a message behind the photo, which says Class 12 (12).

When Huang Ke entered the school, he was stopped by the security guard at the school gate. Huang Ke said that one of his younger brothers was studying inside. He was asked for a parent because of a disaster a few days ago.

The security guard asked him to name the class and the head teacher. Huang Ke took the opportunity to say that he called his brother and then called Zhao Hao.

"Brother Zhao, what other head teacher's name is needed to enter the school? It's so troublesome, why don't I just show the police certificate."

"No, that child is very likely innocent. You go in as a policeman and bring him out. What will the people around him look at him when he is in school in the future? I'll ask Tianqi to check it out for you immediately."

Liu Tianqi, who was sitting next to him, heard the conversation between Zhao Hao and Huang Ke. He hacked into the school's academic affairs system and found the corresponding list of class teachers for all classes. Through monitoring, he knew that the person was from Class 2 (12) in high school, so it was not difficult to find the name of the class teacher.

In less than 5 minutes, he found the head teacher of the second grade (12) class, named Gong Xiu, and the classmate wearing red clothes, named Ding Tao, and even found out the phone number of the head teacher.

After hearing this, Huang Ke returned to the gate.

"My brother said that their class teacher is Gong Xiu, Grade 2 (12) and the phone number is 123xxxxx270."

After the security guard checked the information, he finally put Huang Ke in.

The school is quite big, and when Huang Ke entered, it was still class time, so there were no students on the small road on campus. Huang Ke met two teachers on the way, and according to the route the teacher pointed out, he finally arrived at the door of the second year of high school (Class 12).

At this time, Zhao Hao and Liu Tianqi also learned about the every move at the scene through the camera.

After waiting for about ten minutes, the bell rang and the whole campus came to life again. The first minute was still silent, and the next minute was like a vegetable market. This is the campus.

After the teacher walked out of the classroom, several students behind immediately rushed out of the classroom door and seemed to be rushing to the convenience store. Huang Ke recalled that he lived his high school life in this way.

Huang Ke observed the target person sitting in the last row at the door of the classroom, and it seemed that he was doing his homework. Huang Ke told the person in the first row that he was Ding Tao's brother, so please ask her to call Ding Tao out.

Huang Ke stood at the door and waited, and after a while, Ding Tao walked out.

He looked around and found that there was no one else, only Huang Ke stood at the door of the classroom.

"Are you looking for me?" Ding Tao asked with a confused look on his face.

Huang Ke walked over and hugged Ding Tao's shoulder, and whispered to him. "I am a policeman and am investigating a case now. Please cooperate." When he was sure that there was no one around, he quietly showed his police officer's certificate.

"But the next class is our class teacher's class. If you find out that I'm not here, you will think I've skipped the class." Ding Tao looked embarrassed.
