"The police department, the Kamogawa City Police Department, and Morimura Junior High School have all faxed the list you requested!"

Early the next morning, Lin Xiuyi had just come to the office, and Miki immediately told him the news.

As soon as Lin Xiu heard the news, he didn't brew coffee as soon as usual, he actually sat at the desk in a rare way, and carefully compared the names on the list on the side.

Regrettably, there are no names in common on either list. Lin Xiuyi's guess was denied in an instant.

Lin Xiuyi threw the list on his desk in disappointment, and then got up to fiddle with his coffee utensils.

The jar containing the coffee beans was opened by Lin Xiuyi, and then Lin Xiuyi used a small metal shovel to shovel out some coffee beans and put them on the electronic scale, waiting until enough coffee beans were taken out. Lin Xiuyi picked up the filter paper containing coffee beans on the electronic scale, and then put the coffee beans into a small coffee hand grinder, and then patiently polished the coffee powder.

Ground coffee is not meant to be ground as fine as possible. Only by combining the thickness of the particles and the method of brewing the coffee can the unique aroma of the coffee beans be fully extracted. If you combine coffee beans from different tea origins and roasting methods, it becomes even more complicated. It takes a long time to try to gradually summarize the rules, and the complexity is no simpler than solving a case. Although Lin Xiuyi's method of brewing coffee every day seems to be completely consistent, the coffee brewed every day has subtle changes. So far, apart from Lin Shuichi, the only person who can experience this change is the section chief Matsuda next door.

"Good morning, it looks like the time is just right!"

Section Chief Matsuda came to the special search department with a coffee cup as usual, and Lin Xiuyi was slowly brewing the coffee powder on the filter paper with a spout pot at the moment. With the addition of hot water, the aroma of ground coffee begins to permeate the entire room of the Special Search Department.

About five minutes later, Lin Xiuyi's special black coffee was brewed. Lin Xiuyi removed the filter paper placed on the coffee pot, and then poured the pot of coffee into three cups, no more, no less, just enough for three cups. Miki, Lin Shuichi, and Section Chief Matsuda picked up their respective coffee cups on the coffee table at the same time, and then put them to their mouths and took a small sip carefully. Until this time, Lin Xiuyi felt that the sleeping cells in his body were waking up.

After a cup of coffee, Lin Xiuyi cleaned the coffee utensils and put them back in their places, and then returned to his seat to work.

The information on the list once again failed Lin Xiuyi's hypothesis. But this is not an unacceptable outcome. For criminal investigators, every time a wrong path is confirmed, there is a greater hope of finding the truth next time. When all the wrong paths have been denied, the remaining path is the right path to the truth.

So far, Lin Xiuyi's grasp of the situation of the criminal suspect is still not optimistic. But vaguely, Lin Xiuyi also had some information.

The two victims selected by the suspect clearly had a certain similarity in personality and interpersonal relationships, and were also not good at socializing with their peers, and were often bullied at school. Because of this, it is easier for criminal suspects to obtain new appointments for victims.

In terms of modus operandi, the suspect also has his own unique set. He did not forcibly abduct the victim by force, like ordinary kidnappers. Instead, abduction was used to guide the victim to run away from home. Moreover, before the final abduction, the suspect will instigate the victim to commit a small number of thefts. However, these thefts are not for monetary purposes, and are likely to be a method of psychological control by the suspect over the victim.

In addition to the premise that the above points are relatively large, Lin Xiuyi also has an unconfirmed speculation about the suspect, that is, the suspect may have a certain connection with the University of Tokyo.

As soon as he thought of Dongda, Lin Xiuyi suddenly had a new idea. Is the scope of the investigation a bit conservative? In any case, it should be impossible for a criminal suspect to obtain a new appointment for the victim by just meeting once or twice. Because girls like Tomomi Yano and Arisa Ninomiya are not extroverts themselves. It's not easy to open their hearts.

Therefore, there is a necessary condition for the establishment of a suspect, that is, the suspect must have frequent access to the victim. Because only in this way can the suspect be able to instigate the victim to become a student who dares to engage in theft, step by step, according to his own needs. In this way, the teachers at the school seem to be more suspicious.

Can a career talk turn an introverted girl into a habitual thief? Anyway, Lin Xiuyi felt that this matter was not so easy.

"Miki, can you investigate all the teachers of Morimura Middle School, whether they are in-service or resigned, as long as they have taught Tomomi Yano, they can be traced down in a key way. In addition, I will communicate with Chiba Prefecture to see if I can find the information of the teachers who taught Arisa Ninomiya back then. After we got the list, we focused on investigating whether any of these people had graduated or studied at the University of Tokyo......"

Lin Xiuyi picked up the pen and wrote down the results of his analysis just now.

"You still suspect that the murderer is hiding among the teachers, right?"

Miki heard Lin Xiuyi's command and immediately asked excitedly. It's too painful to sit in an office without an investigative idea, and it's absolutely intolerable for a man of action like Miki to sit in the office and wait for the clues to come to the door by himself.

"I can't think of anyone other than teachers and classmates who can have long contact with the victims and get their new positions!"

Lin Xiu played with the pen in his hand and said helplessly to Miki.

"Police, don't you often say that when all roads start to fail, the rest of the road is the right one? In fact, I felt that the teacher was the most suspicious from the beginning......

Miki said with some smugness. In fact, she has always suspected that the teacher at Morimura School is the murderer she is looking for, but Lin Xiuyi did not investigate in this direction, and Miki, as a subordinate, naturally feels very regretful. To be honest, being able to surpass Lin Shuichi in some aspects other than physical fitness is something that Miki can't even think of!

"Let's check it out first, but I don't think there is much hope that the teachers will commit crimes, because these teachers can't deter the students at all. ”
