Everyone was a little stunned when Qin Jiao heard what she said, and they didn't understand what she wanted to express, and after a while, they all gasped!

"Sun Xiaoqin's grades declined, who is most likely to be the trigger?"

In this case, there is no doubt that it is related to classmates and is a classmate who knows each other.

In addition to the three strands of the girl's hair, there are game consoles, mobile phones, tablets and other valuables in the desks of the same table, which is enough to prove that the same table is related to the case, and the same table is a rich and powerful rich second generation, because the school generally does not allow electronic products.

The case has a new character, Sun Xiaoqin's tablemate Liu Zheng.

"You said before that the murderer is among us, and in your current judgment, the scope of the murderer has been narrowed down to the three of us?"

Qin Jiao bowed: "The teacher's death is inseparable from the bad students in the diary, the three of us are all students, only we know whether we are male or female, and the murderer can lie." ”

Cheng Jibai looked at the box on the table: "If the three strands of hair correspond to three female students with names and surnames, then what is Wang Yu's identity?" Why did he kill himself? ”

This is indeed an unsolved mystery.

Without waiting for them to think about it, Shen Anran suddenly spoke up, interrupting everyone's train of thought.

"Sister, I can't figure it out a little, the person who caused Sun Xiaoqin's grades to decline is not necessarily her tablemate, but also other classmates, why did my sister find Liu Zheng so accurately?"

After Shen Anran finished speaking, everyone looked at Qin Jiao with suspicious eyes.

If Qin Jiao is the actor of Liu Zheng, then it can be explained.

Li Xiaoyue understood, "An Ran, are you doubting Qin Jiao?" ”

Shen Anran pretended to be surprised: "How come?" I just casually asked, if my sister is a murderer, why should she expose herself? Is it to make everyone doubt her? ”

Did they suspect Qin Jiao?

Apparently neither.

They suddenly realized that it was precisely because Qin Jiao had found the bad student that they would instinctively believe her.

Qin Jiao raised her eyebrows slightly, Shen Anran still had a bit of brains, this wave of reverse guidance had a good effect.

However, Qin Jiao's next words made them unable to find faults.

"It's very simple, the teacher found out that something was wrong with Sun Xiaoqin, so he secretly observed her, as a teacher, it is most convenient to observe students in class, so who can easily influence her at this time?"

"At the same table!" Cheng Jibai's voice was clear and loud.

Qin Jiao continued: "In the teacher's diary, there is anger and disbelief, I guess Sun Xiaoqin did not ask him for help, but after he found the problem himself, he made the decision that he thought was right. ”

Zheng Quan hissed: "Qin Jiao, your brain is really fast!" ”

Qin Jiao knew very well that without the guidance of evil spirits, she would not have been able to find a clue in such a short time, but the clues were not enough.

"Each of us has a purpose, Principal Xuan, you don't seem to have said why you came here to investigate the case?"

Qiao Xuan was still very weak, and he slowed down for a while before saying, "There are so many things happening in the school, as the principal, I should lead by example." ”

After listening to Qiao Xuan's explanation, Qin Jiao frowned invisibly, she was silent for a long time, and suddenly pulled the corners of her mouth bitterly.

"I see."

"How?"

Qin Jiao knows the truth?

Qin Jiao ignored their doubts, she looked ahead and sighed knowingly.

"He was a good teacher, and his heart ached when he found out that his students had endured for so long a devastation that did not belong to her age! He's furious! He wants to punish bad students and protect innocent students. ”

"But things didn't go so well, because the bad student was the son of the principal, with the support of the principal's father, the bad student was even more unscrupulous, and the teacher also found more victims, he couldn't bear it, and wanted to solve this matter in his own way, he found the bad student, maybe he wanted to kill him, or maybe he just wanted him to turn himself in."

"The end result is that the bad student killed the teacher, and the bad student and his principal's father knew very well that once the East Window incident happened, those students who were involved in the incident would know whose hands the teacher died."

"Just in case, the father and son decided to solve all those who knew about it, but how to solve it? You can't just kill them, then find a way to make them commit suicide, or fake it as a suicide scene. ”

Cheng Jibai exclaimed: "You mean, Sun Xiaoqin's tablemate is the principal's son?" ”

Shen Anran expressed doubts: "Sister, how do you prove it?" ”

Qin Jiao's tone was calm: "Each of us came to the school with a private purpose, but what Principal Duxuan said was very official, which means that he concealed some of it. ”

Everyone looked at Qiao Xuan, and Principal Xuan was sitting on the chair weakly, without even making a quibble.

"The right family is the mother of a deceased, Teacher Yue is the girlfriend of the male teacher, everyone is more or less related to each other, so what about Principal Xuan?"

"The murderer Liu Zheng is rich and powerful, and the family conditions that meet this point are only Principal Xuan among us."

Li Xiaoyue admired: "Who is the murderer among you?" ”

Qin Jiao raised her hand and pointed at Shen Anran: "The murderer is classmate Ran!" ”
