The next morning, Lin Xiuyi was still on his way to work when he received a message from Chiyo.

"Xiu Yijun, the handwriting you sent over has all been identified, and we are basically sure that these are all the same person's notes!"

Lin Xiu was not surprised when he saw this result, originally Lin Xiu sent these letters to Chiyo just to try his luck. It can now be confirmed that these letters were indeed written by Tomomi Yano, which means that the victim Tomomi Yano should have been placed under house arrest by the murderer before writing the first letter to his family.

This is a brand-new kidnapping and ransom method that Lin Xiuyi has never seen before. The suspect never came forward during the entire crime. According to Lin Xiuyi's current guess. Yano Tomomi should have chosen to run away from home at the instigation of the suspect, and then the suspect would put Yano Tomomi under house arrest and force her to write letters to her family and ask for money. Until Tomomi Yano can no longer satisfy the appetite of the suspect, the suspect will choose to kill Tomomi Yano, so that the only victim who has seen his true face in the entire crime will be silenced forever.

"With such a mature criminal modus operandi, this suspect should not be the first time to commit a crime. Could it be a guy with a criminal record?"

Lin Xiuyi kept making all kinds of assumptions in his mind along the way, and before he knew it, the train stopped at Sakurada Gate. To be honest, since the Tokyo subway bombing, Lin Shuichi can't help but think of the scene when he passes by Sakurada Gate Station almost every day when he commutes to work.

If you look down from the sky, Sakurada Gate Station looks like an ant's nest during rush hour, with hundreds of office workers in suits standing on the side of the road waiting for a green light to pass through it. The crowd will quickly spread to the core institutions of the country, such as the Metropolitan Police Department, the National Police Agency, the Ministry of Justice, and the Ministry of Land, Infrastructure, Transport and Tourism.

Lin Xiuyi quickened his pace and walked towards the Metropolitan Police Department, and after entering the building, Lin Xiuyi used his ID card to enter the internal office area through the turnstile passage. On the road, people kept saying hello to Lin Xiuyi. Lin Xiuyi would nod and salute the other party regardless of whether he knew it or not.

Lin Xiuyi rushed to the office almost every day fifteen minutes before work, and Miki would organize all the work to be done and put it on Lin Xiuyi's desk the night before. To be honest, there are not many cases that the special search department has taken on by themselves, so there is not much work to deal with every day.

Miki has been very diligent since she came to the Special Search Department, and Lin Shuyi knows that she is now preparing for the exam to be promoted to the head of the inspection department. So basically, I won't give her any too much work. According to the Metropolitan Police Department's appreciation requirements, inspectors who have graduated from university can take the promotion exam after one year of work, while junior college requires three years of work and four years after graduating from high school. In addition, the Metropolitan Police Department admits 10 new recruits each year directly through the Category II civil service examination, and they start with the rank of Inspector General.

"Good morning!"

Lin Xiuyi had just picked up the coffee pot and poured himself the first cup of coffee of the day, when Section Chief Matsuda walked in as if uninvited. After Lin Xiuyi put down the coffee pot, Section Chief Matsuda took it and poured himself a cup.

"I heard that you took over the case of Kuwajima and theirs, how is the progress?" Section Chief Matsuda took a sip of coffee, then put down the cup and asked Lin Xiuyi casually.

"It's just the beginning, but from the information I have so far, I think he should be a repeat offender!" Lin Xiuyi leaned into a chair and discussed the case with Section Chief Matsuda while drinking coffee.

"Police Department, do you already have an idea?" Miki asked with some surprise when she heard Lin Xiuyi's words.

"I can't talk about any ideas, just a little speculation! This morning, Inspector Tanaka just told me the results of the note appraisal. Just like I guessed. The letters, requesting the money, were written by the victim, Tomomi Yano. Although it looks like a runaway daughter is asking her family for living expenses, it is actually a blackmail letter......"

Miki had also read these letters, and Miki deeply agreed with the blackmail mentioned by Lin Xiuyi. In these letters, Tomomi Yano would ask her mother to send her money every once in a while, and although the reasons were different, she would always imply in the letters that she had reached the point of exhaustion, and if she didn't send money, she would have to sell her body.

"It's a ransom letter!"

As soon as Lin Xiu's words fell, Sang Dao's seniors took his subordinates to the special search department. Since last night, the Kuwashima Police Department has been reading these letters written by Tomomi Yano to his family. The Kuwashima Police Department also has a daughter, so he can understand Mrs. Yano's feelings when she receives these letters. Despite all the unpleasantness with her daughter, at the last moment, both the mother and the father will choose to do what the letter asks.

"This suspect is so hateful that he has never been seen from beginning to end, so that the bereaved parents always think that it is just the child running away from home because of a moment of anger. What's even more odious is that he actually took advantage of his parents' concern for their children to blackmail. Even the extortion letter is forced to be written by the victim himself......"

"Kuwajima senior, have you or any of the other seniors ever encountered a similar case before? Judging from the modus operandi, it should not be the first time that the murderer has committed a crime. ”

"Probably not, to be honest, it's the first time I've seen such a kidnapping and ransom case! It's too hidden, and most importantly, the suspect's way of squeezing the ransom is also very skillful. And in the end, once the suspect can no longer squeeze the money from the victim to his satisfaction, he will actually choose to kill the victim directly and dismember the body, the method is both clever and cruel, if such a person has a criminal record, I am afraid there is no chance to get out of prison at all......"

As soon as Lin Xiu heard the words of the Mulberry Island Police Department, he nodded silently. yes, if this guy had been caught for the same crime before, he probably wouldn't have had a chance to get out of prison. This is a felony of kidnapping and homicide.

"If that's the case, I'm afraid Tomomi Yano won't be the only victim!"

Lin Xiuyi sighed and said with great regret. He then suggested to Kuwajima's seniors:

"Kuwajima-sen, this murderer is really a bit special, but I always believe that this is not his first crime. So I'd like Aizawa and Hanagata to stay and find out if there are any similar cases that haven't been solved yet, and to check the internal database to see if there are any prisoners who have been sentenced lightly for attempted kidnapping and extortion. In addition, there is a third possibility, that is, the murderer has killed other victims before, but disguised the victim's death as a suicide and other cases that the police will not notice. ”
