"Is this ......" I asked, looking at the red note.

"I don't know what it is, look at Team Shao, there are some words written on it."

I took it and looked at it, and sure enough, it was written in a crooked font:

See you on the rooftop at 12 o'clock at noon, you know what you've done. If I hadn't seen you at half-past twelve, some pictures of what you did would have been posted on the Internet.

"It's like ......"

If I remember correctly, this note is likely to be the one Zhang Yucai held in his hand when he entered the school!

"Qian, what do you think?" I asked.

"Well......" she put her chin on her hand, thought for a moment, and then said, "It seems to me that the writer of this note is either a person with a very low level of education and extremely ugly handwriting, or a person with a high level of education, but deliberately writes this note with his left hand, or by non-habitual hand. ”

"Makes sense." I agree.

If it was really left-handed, then the person was probably worried that his handwriting would be recognized. Since he was worried that his handwriting would be recognized, the person who wanted to write a note to Zhang Yucai was probably the person who Zhang Yucai had seen his handwriting......"

I snapped my fingers, walked to the window, looked outside, and said, "As a teacher, Zhang Yucai has access to whose handwriting?" I believe that he is most familiar with the handwriting of his students! ”

Ouyang Qian looked at me and asked, "Team Shao, are you still insisting that this case was done by a student?" ”

I turned my head and replied uncertainly, "I don't have enough evidence right now, but I've been suspicious ever since you told me that the man in canvas shoes who appeared on surveillance in the classroom was probably a student.

"And not only that, but my instincts also told me that his students must have some ulterior relationship with this teacher."

"Okay Team Shao, what are you going to do with this note?" She asked, looking at me, waving the little pink note in her hand.

"I have an idea."

I pulled Ouyang Qian over, pulled her to the window, and pointed to the balcony, and said to her, "See that side?" ”

"Huh? Balcony, what's wrong? She asked, puzzled.

"The balcony, the balcony! If I remember correctly, when we first saw the corpse, he was facing us with his head tilted and tilted out of the window. You say, could the murderer want to tell us what happened on the balcony and has something to do with Zhang Yucai? ”

After speaking, I snatched the note from Ouyang Qian's hand, then held the note up to her, and said: "This note says, 'You know what you did', so will the 'thing' mentioned above also have something to do with this balcony?" ”

Ouyang Qian looked at me and made an expression of sudden realization:

"I understand Team Shao, what do you mean is that this note may be the murderer's way to lure Zhang Yucai to this place, he saw what Zhang Yucai was doing on the balcony through this window, and also took a photo! He used this to blackmail Zhang Yucai so that he could come to school on the day of the crime! ”

I smiled, then gently stroked Ouyang Qian's soft hair, and said appreciatively, "Great, you can understand what I mean at once now." ”

"But......" She didn't respond to my compliment, but lowered her head and played with the note in her hand again.

"Don't you think it's weird? Team Shao, I found this note on the podium of this classroom, but we didn't find it when we surveyed at that time. Could it be that they missed such an important clue? ”

I frowned again all at once.

That's right, the joy of being found this new clue just occupied my mind, but I forgot to ask Ouyang Qian where she found this note.

"Well, this case becomes very interesting."

I smiled, and then said to Ouyang Qian: "Qian, let's go back to the police station first, if there are other people's fingerprints or DNA clues on this note, then we can pick up the treasure." ”

"But, Team Shao, let's ......" I didn't have Ouyang Qian, who didn't fully understand what I meant, but turned around and left the classroom, taking the note, ready to return to the police station.

In my thoughts, there are two points. First of all, the person who wrote the note will most likely leave their fingerprints on the note. Because they don't expect the note to be found by the police, they may not be aware of clues such as fingerprints that can reveal their identity when they write.

Secondly, this note was held by Zhang Yucai all the time, so the murderer may not have thought that he would take this note with him. According to the logic of ordinary people, when you get a threatening note, your first reaction should be to leave the note at home for an appointment, or tear it up on the spot.

Instead of being brought to the scene like Zhang Yucai.

Unless......

Unless he already understands who the person who wrote this note is!

So, regardless of whether we really missed that note when we first surveyed the scene, we can choose to keep this important clue.

Not to mention that the fingerprints on it will give us direct information about the identity of the suspect, and we can even ask a handwriting expert to analyze the note.

When Ouyang Qian and I returned to the police station, we found that Zhang Yucai's wife was arguing in the police station. It was completely different from how polite she had been that day.

"Shao Feng, you are back, you have been here for a long time, and it has completely disrupted our normal work! You come to help persuade her...... "It was the director who came to greet me, but I didn't expect him to come out and coordinate this matter in person."

I patted the chief on the shoulder, indicating that it was on me.

"Ms. She, if you have anything to say, come and tell me, don't pester those police officers who still have jobs." I walked up slowly and said to She Jiao, who was still making a lot of noise.

She Jiao turned around and saw that it was me who had returned, so she immediately rushed over to me and said, "Officer Shao, you are finally back." I'm here today to see how you're doing, but I find out how you haven't even noticed the shadow of the murderer! ”
