At present, these two people are involved in the case, and I am not sure if the third warning from the other party is to completely kill Xu Zhisheng."

Jiang Chengdong also understood the seriousness of this matter, as a people's policeman, it was impossible for him to watch an innocent life under threat, and nodded:

"It's nature."

"Thank you very much."

Lin Juan suddenly felt that the burden on his shoulders was much lighter.

Jiang Chengdong asked some more questions, and Lin Juan said it according to the actual situation he knew, and quickly lifted the interrogation.

Lin Juan came out of the interrogation room, Su Li saw that his face was pale, and rubbed his face with some distress:

"Shall we go back first?"

"Nope." This time, Lin Juan shook his head, "I'm going back to school, there is still time until nine o'clock in the evening, and I have to grab at least something before I officially meet with the enemy."

…

Lin Juan returned to the school and soon found the art room where Chen Taotao's body was said to have been found.

Unexpectedly, this art room and the piano room used by Zhong Chulu to play the piano at that time were in the same art building, and they were closely connected.

On the way to the art building, Lin Juan heard many students around him whispering that two people died in a building one after another, and this time the school was able to suppress public opinion and not publicize it, but it couldn't suppress the mouths of the students in the school.

Soon all kinds of supernatural rumors spread, some people said that the building was haunted, and they specially picked young girls to start and put on their bodies to mix among the students, and some said that the feng shui of that building would make people fall into bad luck.

Lin Qian turned a deaf ear to these outrageous rumors, slowly climbed the stairs, and looked at the art room in front of him that was covered with police seals.

Because they were worried that some students' excessive curiosity would cause them to enter and leave the crime scene and destroy the first scene, the police put the seals densely together.

Lin Juan naturally couldn't tear open those seals, so he could only glance through the gap in the seals, the art room was empty, there were still some dry colored paint spots on the floor, and his eyes moved up, and there was a rusty iron hook in the middle of the ceiling.

Did Chen Taotao just hang herself there?

Lin Juan and the others retracted their gaze and fell on the lock of the door of the art room, this classroom is not usually used as an ordinary classroom, so it will not be open every day, only a few students who use this classroom for self-study have the key to this art room.

The person who found the body must have been one of the people who could use the art room.

Lin Qian glanced at the tools stacked in the corner, there are a total of four easels, and there should be four students who have the key to this classroom, of course, it is not ruled out that teachers or school staff may also have the key.

Lin Qian made up his mind, slowly walked downstairs, went to the security office on the first floor, and asked who had borrowed the key to the art classroom.

The security department apparently received the notice about the case early, and as soon as they heard someone ask, they immediately waved their hands, saying that they didn't know, and their faces were full of impatience.

Lin Juan asked two questions, and the security uncle became angry:

"You students, you don't study every day, and it's useless to pay attention here! I told you everything, I don't know!"

Lin Juan was taken aback, and when he saw that the security uncle had turned around, he didn't intend to pay attention to him at all, so he could only give up.

Why don't you go back and ask the students of the art department......

Lin Juan walked on the road with his head down and pondered, and suddenly a pair of stopped shoes appeared in front of him, and it was too late for Lin Juan to stop his steps, and he suddenly bumped into the other party's arms.

"I'm sorry!"

As soon as Lin Juan spoke, he heard a familiar chuckle in front of him.

When he raised his head, it was Su Li, who looked at him, and suddenly took out a piece of paper from behind him:

"Look, what is this?"

Lin Juan took it curiously and found that there were several names written on it, some of which were crossed out with red lines, and only four remained.

This name later recorded the movements of these four people, what they did, and who could provide them with an alibi during the period from the night when Chen Taotao went to meet Tingting to today, when Chen Taotao's body was found.

Very detailed, Lin Juan looked up in surprise:

"You're going to ask?"

"I happen to know a student who is from the art department and a mystery fan, I told him that this was a task given to me by the police, and he immediately rushed to ask for me."

Thinking of that scene, Lin Juan couldn't help but laugh a little.

After carefully re-reading the rewritten content on the note, Lin Juan found out what the problem was, the four people written on the note, all had an alibi outside during the time when Chen Taotao's body was found today.

And who is the person who called and reported the discovery?

Lin Juan called Jiang Chengdong and briefly explained to him how he came to the school after coming out of the police station, and Jiang Chengdong fell silent when he heard that the four students who could use this artist had alibi.

It wasn't until Lin Juan called him softly that Jiang Chengdong came back to his senses:

"Is it possible that they lent the key to someone else? Or did someone else borrow the key from the guard?"

"Is there any borrowing record in the security department, if the police go to investigate, the security guard should open up." Lin Juan paused, "But I don't think it's very likely, the other party is obviously carefully premeditated, and he won't leave such lame traces."

Su Li also interjected beside him at the right time:

"I asked this question when I asked them, and the answer was no, but they don't usually look at the key closely, and if someone secretly takes the key to get one, it is difficult to be detected."

"Really? And that's where the clue is broken again......

Jiang Chengdong's voice was a little low, and he seemed to be in deep thought.

"It's not broken." Su Li interrupted his thoughts, "Officer Jiang, you can check the surveillance camera near the art building, check the people who entered the art building that day, now that graduation is approaching, there are not many people who go to the art building, if you just go to the classroom for self-study, let them report the house number of the self-study classroom, I remember that there are monitoring probes in each classroom, and you can see through the monitoring whether they are really in an unrelated classroom the whole time."

Su Li raised his head and glanced at Lin Xuan.

Of course, the surveillance probe in the art room where the crime occurred had already been maliciously vandalized, leaving no valuable clues.

"I see, I'll check it out later." Jiang Chengdong paused, and suddenly turned to Lin Xuan to speak, "Are you going to the other party's agreed location tonight?" Do you need me to send more police to follow you to keep you safe?"

"No, I don't." Lin Juan shook his head and vetoed, "The other party said that they want me to go alone, now they are in the dark, we are in the light, if they anger the other party, I don't know what they will do next."
