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

"Xiu Yi-kun, all the handwritings you sent have been authenticated. We can basically be sure that these are all the notes of the same person!"

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

This is a brand-new kidnapping and extortion method that Lin Xiuyi has never seen before. The suspect never showed up throughout the crime. According to Lin Xiuyi's current guess. Yano Tomomi should have chosen to run away from home under the instigation of the criminal suspect, and then the criminal suspect would put Yano Tomomi under house arrest, forcing her to write letters to her family constantly asking for money. Until Tomomi Yano can no longer satisfy the suspect's appetite, the suspect will choose to kill Tomomi Yano, so that the only victim who has seen his true face in the entire crime process will always shut up.

"With such a mature criminal technique, this suspect should not have committed a crime for the first time. Could it be a guy with a criminal record?"

Lin Xiuyi kept making various assumptions in his mind along the way, and before he knew it, the train stopped at Sakurada Gate Station. To be honest, since the Tokyo subway bombing incident, Lin Xiuyi can't help thinking of the scene when he passes by Sakuradamon Station almost every day to and from get off work.

If you look down from the sky at this time, the Sakurada Gate Station is like an ant's nest during the rush hour. Hundreds of office workers in suits stand by the roadside and wait for the green light to pass. Once the green light turns on . The crowd will quickly spread to the nearby Metropolitan Police Department, the National Police Agency, the Ministry of Justice, the Ministry of Land, Infrastructure, Transport and Tourism and other core institutions of the country.

Lin Xiuyi quickened his pace and walked towards the Metropolitan Police Department. After entering the building, Lin Xiuyi used his ID to enter the internal office area through the gate passage. On the road, people kept saying hello to Lin Xiuyi. Whether Lin Xiuyi knew him or not, he would nod his head in return.

Lin Xiuyi rushes to the office fifteen minutes before going to work almost every day, while Miki will organize all the work to be done on Lin Xiuyi's desk the night before. To be honest, there are not many cases that the Special Sou Department has taken over, so there is not much work to be dealt with every day.

Miki has been very diligent since she came to the Special Investigation Department, and Lin Xiuyi knew that she was now preparing for the exam to be promoted to the inspector general. So basically, she will not be given too much work. According to the Metropolitan Police Department's appreciation requirements, inspectors who graduate from college can take the promotion exam after one year of work, while short-term colleges require three years of work and four years for high school graduation. In addition, the Metropolitan Police Department will directly admit ten new recruits through the civil service examination every year, and their starting level is the Minister of Inspection.

"Good morning!"

Lin Xiuyi 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 over and poured himself a cup.

"I heard that you took over the case of Kuangdao and the others, 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 what I know so far, I think it's a repeat offender!" Lin Xiuyi sat on a chair, drinking coffee and discussing the case with Section Chief Matsuda.

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

"I can't talk about any ideas, just a little speculation! Inspector Tanaka just told me the results of the note appraisal this morning. Just as I guessed. These letters asking for money are all from the victim Yano Tomomi. Although it looks like a daughter who has run away from home begging her family for living expenses, it is actually an extortion letter.”

Miki has also read these letters, and Miki deeply agrees with the extortion statement mentioned by Lin Xiuyi. In these letters, Yano Tomomi would ask her mother to send her money every now and then. Although the reasons were different, she always implied in the letter that she had reached the end of her life. If she did not send money, she would You have to go and sell your body and other words.

"It is indeed a blackmail letter!"

As soon as Lin Xiu finished speaking, Senior Kuangdao brought his subordinates to the Special Search Department. Since last night, the Kuangdao Police Department has been reading these letters written by Tomomi Yano to her family. The Kuwashima Police Department also has a daughter, so he can understand Mrs. Yano's mood when she received these letters. Despite all kinds of unpleasantness with her daughter, at the last moment, both the mother and the father will choose to follow the requirements of the letter.

"This suspect is really abominable. He never showed up from beginning to end, so that parents who have lost their loved ones always think that this is just a child who ran away from home because of a momentary anger. What's even more abhorrent is that he actually took advantage of the parents' concern for their children. to blackmail. Even the blackmail letter is forcing the victim to write it himself.”

"Senior Kuangdao, have you or other seniors encountered a similar case before. If you look at the method of crime, it should not be the first time the murderer has committed a crime."

"No, to be honest~lightnovelpub.net~ This is the first time I have seen such a kidnapping and extortion case! The concealment is really too strong, and most importantly, the way the suspects extract ransom is also very good. Skilled. And in the end, once the suspect can no longer extract money from the victim that satisfies him, he will 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 If so, I'm afraid there is no chance of getting out of prison at all."

Lin Xiu nodded silently when he heard the words of the Sangdao Police Department. Yeah, if this guy had been caught for the same crime before, he probably wouldn't have had the chance to get out of jail. This is a felony of kidnapping and murder.

"If that's the case, Yano Tomomi may not be the only victim!"

Lin Xiu sighed and said with great regret. Then he suggested to Senior Kuangdao:

"Kawashima-senpai, the murderer this time is really special, but I always believe that this is not his first crime. So I want Aizawa and Hanagata to stay and check if there are similar but unsolved cases. , and also look in the internal database to see if there are any criminals who were eventually given light sentences for attempted kidnapping and extortion. In addition, there is a third possibility, that is, the murderer has also killed other people before. the victim, but disguised the victim's death as a suicide and other cases that the police would not notice."
