The policeman next to the white gloves wandered around, surveying every suspicious corner.

"Oh? How do you know that it is not? Don't think that you can become a famous detective by learning a few criminal investigation methods. The first thing you do in our business is to collect a lot of information and find the details related to the case from it to screen the suspect."

Xia Qinian sneered and disregarded Ai Liang's statement. This was obviously what the young man who liked to show off his mind would say.

"First, if it is done by Gaofuye's business rival, it proves that the conflict of interest between the two parties must have reached a white-hot stage, but you did not raise it immediately. Gaofuye only used the media to put pressure on the police to prove that he had no object of suspicion, so the conflict of interest can be ruled out."

Ai Liang did not look back at Xia Qinian's expression, but just stared at the school quietly.

"Second, if Gao Jiajia's death is a warning from a business opponent to Gao Fuye, it is completely impossible. Gao Fuye is only one daughter, and you can imagine how much love she is. Will you kill your opponent's only relative in order not to anger your opponent? This will only make Gao Fuye defeated the death."

"Third, if it is an old grudge, there is no need to kill Gao Jiajia at school. After school, there are students and snack stalls everywhere near the school, and cameras are everywhere. Are you afraid that you will not be exposed? Wouldn't it be more convenient to wait until Gao Jiajia comes home or find an alley on the way home to strangle it?"

"Fourth, Gao Jiajia's death is almost 9:00 to 9:30 after school. If a person in the society enters the school, he will definitely be required to register by the security guard. As for climbing over the wall, you should have never seen the surrounding environment of the school after school, right? The snack carts surrounded the school."

"As for the death place outside the school, would you walk into the school with a body in front of everyone? Even if you come in in the middle of the night, the surveillance of the stairs is not a decoration."

Xia Qinian in the driver's seat held his cell phone in a daze. At this time, Ai Liang turned around and looked at him and began to make a summary.

"Outsiders should not know that many places in our school, including the staircase, are equipped with cameras. Whether Gao Jiajia was strangled elsewhere or in the teaching building, since her body was hung at the door of the class to pretend to be suicide, the murderer would definitely be exposed to surveillance. The police must have retrieved the relevant videos. Since the murderer had not confirmed last night, it proved that the camera was not taken at all or that it was not working."

"I'll guess boldly. Since Gao Jiajia was hung at the door of her class, does it mean that the murderer knew Gao Jiajia, so he knew which class she was in? Not only that, the murderer must be very familiar with the environment near the school, because if you want to turn off the camera, you need to go to the electric box on the first floor in advance to move the switch."

"Why should Gao Jiajia enter the dark teaching building? Or will a girl stay stupidly in the dark after the power outage in the teaching building? It is likely that an acquaintance is looking for her."

"So the murderer is probably someone in the school, a student, a teacher, a security guard, and the possibility of these people is far greater than that of others."
