"Ink, paper, and envelopes are all common colors on the market, and there is no value in tracking them down at all!"

"Chiyo-san, how do you know if you don't try?"

Lin Xiuyi pleaded without giving up.

"Lord of the Police Department, your class is higher than mine, it's not appropriate to call me Chiyo Sister, and besides, I hate people calling me Sister the most, especially male ......"

Chiyo Tanaka angrily rejected Lin Shuichi's proposal.

"Could it be that Chiyo-chan, who is omnipotent, really has no way this time?"

Lin Xiuyi pretended to be surprised and said.

"I'm sorry, you can take these letters back now, I think our identification is over!"

After Chiyo Tanaka finished speaking, he was angry and put the evidence box that Lin Xiuyi had sent over into his arms. Then he picked up a report on the table and pretended to be busy, ignoring Lin Xiuyi.

"Ah......h

"No......"

Lin Xiuyi still wanted to say something, but unfortunately he had just taken a breath and was blocked back by Chiyo Tanaka. In desperation, Lin Xiuyi could only leave the forensic class with the evidence box in disappointment.

Although he was rejected by Chiyo, Lin Xiuyi did not have any dissatisfaction with Chiyo because of this matter, in the final analysis, even he felt that the proposal just now was a bit difficult for a strong man.

Ink, paper, and envelopes are all common colors, which means that the manufacturers of these products have a wide range of sales channels and strong production capacity. The identification class simply didn't have the energy and time to satisfy Lin Xiuyi's thoughts.

However, Lin Xiuyi did not give up, because Lin Xiuyi had not had time to track down the postmarks on these letters, since these letters were sent by the prisoners, it also meant that these postmarks could roughly show the area of the prisoner's activities.

Lin Xiuyi returned to the office of the special search department with the evidence box, he quickly cleared out an empty table, and then Lin Xiu initially placed the letters on the table in order of time.

The information on the postmark is very simple, and it will generally indicate the source of the email. There were a total of twenty-seven letters in Lin Xiu's hand, and he quickly arranged them separately according to the area where they were mailed.

Among them, the number of letters stamped with the Bunkyo postmark is the largest, with a total of 7, which means that 7 mails were sent from Bunkyo Ward.

The next largest number of letters were postmarked by Meguro, with a total of 5 letters, which proves that these 5 letters were sent from Meguro Ward.

Of the remaining letters, there were four from Minato Ward, four from Nakano Ward, and three each from Nishitokyo City and Mitaka City, which are affiliated with the Tokyo Metropolitan Government. As for the last letter, it came from Musashino City, where Morimura Junior High School is located.

If you look at the areas where these letters are sent on the map, Lin Xiuyi didn't find any patterns. It appears that the prisoner was somewhat indefinite, and the place where the letters were sent was not fixed. Was this intentional on the part of the prisoners, or was there a real need to send letters in these areas?

While Lin Xiuyi was studying these postmarks and trying to find out the possible patterns of the prisoner's activities. Miki suddenly returned to the office, and as soon as she saw Lin Xiuyi, she said excitedly:

"Police, I just found a similar case in the database, but not in Tokyo, but in Kamogawa City, Chiba Prefecture......"

As soon as Lin Xiu heard Miki's excited narration, he immediately stopped what he was doing. followed Miki to the front of the computer.

Miki quickly opened the data search network within the Metropolitan Police Department.,After entering keywords such as the girl's disappearance.,Theft.,And set the time.。 A number of related cases were quickly listed on the screen.

Miki flipped through a few pages until she found a disappearance that happened in Kamogawa City, Chiba Prefecture 2 years ago, and then returned the mouse to Shuichi Hayashi.

Lin Xiu opened the relevant information of this case a little, and then read it carefully with Miki.

The case was a disappearance that occurred two years ago, and the missing girl named Arisa Ninomiya was a student at a private middle school in Kamogawa City. According to the records, Arisa Ninomiya usually doesn't seem to fit in well at school, and is always ostracized by her classmates. However, when Lin Xiuyi saw the girl's ID photo, he felt that she was the same as Tomomi Yano.

Arisa Ninomiya's appearance is also quite cute, and even the family conditions are similar to Yano Tomomi. From this point of view, if the cases can be combined, Lin Xiuyi seems to have found the suspect's preference when selecting the victim

However, it is more similar to the fact that Arisa Ninomiya was taken to nearby Koban for stealing goods at a convenience store on the afternoon before her disappearance. After the patrol officer informed Arisa Ninomiya's parents, her parents took her home, and until the next day, Arisa Ninomiya went to school as usual, and never returned home since.

Arisa Ninomiya's parents sent a letter from under her pillow explaining that she had run away from home after she ran away from home. It is precisely because of the existence of this letter that the police at first simply investigated the whereabouts of Arisa Ninomiya, until a few days later, after Arisa's parents found a letter sent by their daughter home asking for living expenses outside the home, the police finally confirmed that the case was indeed a runaway case because of the notes of the letter, and then closed the case.

Originally, Arisa Ninomiya's parents thought that their daughter would return home soon. Because their daughter promised in the letter that she would definitely return home as soon as she received the money. But then they found out that things were not what they had expected. However, because the police have already closed the case, and Arisa Ninomiya's handwritten letters are sent to her home from time to time, the police cannot reopen the case in the name of the disappearance case (the principle of one case is not two cases in the Japanese Criminal Procedure Law), and cannot prove that Arisa Ninomiya has been killed or controlled by others, so until now, Arisa Ninomiya is still a missing person whose whereabouts are unknown.

After Lin Xiuyi and Miki read the information about this case, they stood up in unison and began to pack their things.

"Miki, Kamogawa City, Chiba Prefecture, contact them on the way and tell them that we need access to all the information about this case, and that it would be best for us to have an interview with the family. ”

"Understood, police department!"

……

Lin Xiuyi and Miki walked out of the office of the special search department one after the other, and the two of them sorted out their belongings as they walked. Lin Xiuyi had a bad premonition, that is, maybe there were more victims waiting for Lin Xiuyi to discover. Because like Tomomi Yano's case, Arisa Ninomiya's case also has a very high degree of completion, and this is by no means something that can be learned overnight.
