"Usami-san, I remember that there was a time when you and your friends seemed to be in constant contact with Tomomi Yano-san, can you tell the teacher if Tomomi Yano had anything different from usual before she disappeared......"

At the request of Lin Shuichi, Miki rushed to Morimura Middle School alone the next morning to continue investigating the situation before Yano's death. However, in order to avoid his identity as a police officer, he caused unnecessary trouble to the investigation. Miki can only ask the teacher from Morimura Middle School to come forward and ask the police about Tomomi Yano's life instead of the police.

"Teacher, so what, in fact, we don't get along with her very well, it's just that she always wants to join us, and we are forced to accept her ...... because we can't help it."

As soon as Yano Tomomi was mentioned, her former classmate Usami immediately showed a look of disdain. Even if the teacher was present, Usami didn't have the slightest intention of restraint. However, she glanced at Miki who was present curiously, and Miki saw her gaze and immediately responded to the other party with a smile. This made Usami's vigilant heart relax a little.

"This new teacher is quite cute when he laughs, but I don't know what the personality is?" Usami muttered to herself.

"Usami-san, you said that Tomomi Yano wants to join you, can you tell me how to stalk?" Miki saw that the teacher at the school didn't know how to proceed with the application, so she immediately asked Usami about some specific situations.

"Teacher, are you new here, I don't think I've seen you before!" Usami asked Miki curiously.

"Then I'm going to ask Usami-san to take care of me in the future?" Miki smiled and bowed to Usami.

Usami also hurriedly returned the salute when she saw this, although they didn't think the teacher was great at school, but there was still respect for politeness. Besides, this new young female teacher looks gentle and cute, and she is really likable!

"Actually, it's not a big deal, it's just giving us some lipstick, mascara or something. It's all worthless things, but for the sake of her sincerity, we accepted her so-so......" Usami replied to Miki with a completely different attitude than just now.

"Do Usami-san use these things too, you're cute now!" Miki asked, pretending to be surprised.

"Some people there think they're too pretty, but I only use it occasionally?" Usami said embarrassedly.

"But Usami-san, the teacher's eyelashes occasionally get into her eyes, which makes it uncomfortable?" Miki said to Usami suddenly rubbing her eyes.

"What brand of mascara is used for the teacher, I think Shiseido majolica love magic mirror is good, I highly recommend the teacher, you are also this one!"

"Oh, yes, I'll definitely try you when I go back, but, Usami-san, you just said that Yano-san's mascara gave you, is this one?"

"yes, I didn't want it, but it was really good to use, so I took it......"

……

After a morning of questioning, there are rumors in the high school of Morimura Middle School that there is a new female teacher with a cute personality and sweet appearance in the school. This incident spread throughout the school through the mouth of female classmates, and it quickly aroused the strong curiosity of male classmates in the same school. But at this moment, Miki has achieved the purpose of her trip, and she can now confirm that Yano Tomomi should have used the stolen goods she stole to give to the female classmates who had bullied her.

After Miki returned to the Metropolitan Police Department, she immediately reported the incident to Lin Xiuyi. Although this is only a small detail, he fills in an important link in Lin Xiuyi's analysis of the case - the whereabouts of the stolen goods.

Under the new assumptions, the progress of the case seems to be moving in a smooth direction, which undoubtedly brings some confidence to the special search department.

……

"Police, what do we need to do next?" After Miki reported the results of the investigation to Lin Shuichi about Morimura Middle School, she curiously asked about the next step of the investigation.

"Miki, what do you think if Tomomi Yano really has an accomplice, what kind of purpose will this guy be in to assist Miki in stealing these things that have no economic value?"

Lin Xiuyi leaned back in his chair and played with the pen in his hand. Previously, under the assumption that Tomomi Yano had accomplices and Tomomi Yano was skilled in his modus operandi, Lin Shuichi successfully found the reason for Tomomi Yano's popularity after entering high school and the final destination of Tomomi Yano's theft.

But what Lin Shuichi doesn't understand now is why Tomomi Yano's accomplices would help her steal these things that have no financial benefit. After these items were stolen again, they were given to other girls at Morimura Middle School. Is this to attract more girls?

"Miki, I want you to investigate if there are any girls who are as missing as Tomomi Yano, and they also have a history of theft. If there are similar cases, I would like to put them together and look them up separately to see if there is some connection with Tomomi Yano's case?"

"I understand the police department, I'll go now!"

Miki is a man of action, and after getting Lin Xiu's instructions, she immediately went to investigate. Lin Xiuyi slowly got up from the chair, picked up his coat, and then left the office directly.

Hundreds of times at the scene, this is a valuable experience that generations of criminal police officers have taught their younger generations in search of a lesson. It is also Lin Xiuyi's favorite thing to do when he encounters difficulties in solving cases. However, in today's society, with the diversification of crime forms, many valuable experiences that were previously regarded as wise sayings are gradually beginning to be unable to adapt to the new forms of crime.

Just like in many cases now, suspects often use anonymous methods to find potential victims on the Internet, so some information on social platforms has begun to be more and more valued by the police. In a way, it seems that social media platforms can already be regarded as another crime scene.

However, in the case of Tomomi Yano, the police did not find any suspicious signs from Tomomi Yano's social information before her death. And the way the suspect constantly forced Tomomi Yano to ask for money from home was actually traditional letters, which is very distinctive, so can you investigate the source of the ink, paper and envelopes of these letters?
