"I also want to have some impression about this case. I saw it on TV several times at that time."

After repeated reminders by Bai Yan and Zhenyu, officer Gaomu also remembered the case and recalled: "The only clue to the planned crime after detailed planning is the picture taken by the bank camera for less than ten seconds. What exactly was the dead police officer locking in the criminal after his death has become an unsolved mystery, but unexpectedly, he was the father of police officer Sato."

Sergeant Sato had finished praying, walked to the people and said calmly, "it can't blame you. Even if the case and the suspect's name were still in people's memory, no one will remember who the police officer died in that case except the relevant persons of the police."

"Officer Sato..." officer Takagi and officer bainiao looked at officer Sato and didn't know what words to comfort her. After all, this is the reality.

However, officer Sato is not a weak woman. He doesn't indulge in sadness too much. He smiled relieved and said: "in fact, we are police, and we don't work hard to make people remember. Just be ourselves."

Bai yanzhenyu was a little impressed by the melancholy Lang incident in the original book, but after so many years, he had long forgotten the details. While trying to recall, he asked, "officer Sato, didn't the truck driver see the prisoner's face at that time?"

Officer Sato shook his head and replied, "it is said that the robber was wearing a long raincoat, so the driver was not sure whether he was male or female. Even the robber photographed by the bank camera was wearing a hat, sunglasses, mask, coat and tightly wrapped."

Guangyan was a little confused and said, "but don't you already know the prisoner's name is' melancholy Lang '?"

Officer Sato smiled and helplessly explained, "yes, the police also investigated according to this clue, but none of the people named by this name met the crime conditions."

There are too few useful clues. Bai yanzhenyu and Conan are helpless about it. They sigh: "the clues are only the pictures taken by the monitor. The prisoner is wearing a raincoat and 'melancholy Lang'. No wonder that case will become a pending case."

Who knows, after listening to Bai Yan Zhenyu's words, officer Sato shook his head and said, "no, there is another clue. It is the suspicious words [Kan] and [O] recorded in Katakana in my father's police manual."

"[Kan] and [O], this is the first time I heard it." everyone was stunned after listening. Unexpectedly, there was such an unknown clue.

Officer Sato leaned against the car and explained, "the police don't want this to be leaked out. From the records before and after, the police judge that it has a great impact on the case. Therefore, after the incident, the police often asked me and my mother if we had heard my father mention such words."

Baiyan Zhenyu and others looked at officer Sato in a state of memory and asked, "then?"

"We have never heard a similar word, let alone understand its meaning."

Officer Sato reluctantly spread his hand and said with a bitter smile: "I remember staring at these three words when I was a child, so I was particularly impressed. I often thought in my heart that whoever can solve this puzzle and catch Chou Siro, no matter what he asked, I will promise him."

"Is anything OK?"

After hearing officer Sato's words, officer Takagi and officer bainiao suddenly saw the scene of her marrying herself in a wedding dress in their minds. Then they looked at each other and showed an expression of intransigence.

"If I guessed you, would you like to treat me to a hundred eel meals?"

"I want to go to trobi Park, can I?"

"If it's me, I'd like a ticket to the international cosmos station."

The Bumei trio are also interested in this topic and express their wishes one after another. However, at the level of the three of them, it is estimated that they will not be able to solve this case in their life.

Baiyan Zhenyu pretended to be casual and asked ash yuan: "ash yuan, if you choose, what do you want?"

Ash Hara AI glanced at Bai Yan Zhenyu and replied, "if I were, I would probably want a Prada brand leather bag."

"Prada's brand-name leather bag."

Baiyan Zhenyu kept this thing in mind silently. When he was about to speak, he suddenly found four elderly people coming here, and a short man headed by him was holding a bunch of white lilies to express his condolences.

After looking at these people, officer Sato greeted them inside, smiled and said, "everyone, I haven't seen you for a long time."

Facing officer Sato who greeted them, the four were slightly stunned. Then the only woman recognized officer Sato and said in surprise, "eh? Aren't you meihezi?"

"Meihezi?" another slightly fat man in red also said, "I didn't expect you to have grown so big..."

"Yes."

Officer Sato smiled and then introduced to Bai yanzhenyu and others: "they are friends of dad's baseball team in high school..."

The only woman was the team manager of the school baseball team, Shenniao diezi;

The slightly fat man in red is the president of a financial company. He was the fourth player in the team, called Zhu baomanxiong;

Wearing a pair of glasses and half frame glasses, it seems that the gentle uncle is a pitcher with officer Sato's father's partner, Shinto xiulang. His current occupation is a teacher;

Finally, the short man with a lily in his hand and no smile on his face is Xiuer Kano, who is famous for his strong arms and fast feet. Now he is the manager of a restaurant.

After that, officer Sato introduced Baiyan Zhenyu and others to them, and then asked curiously, "by the way, how did you get together today?"

"Because we haven't seen each other for a long time, we want to get together for a drink." ape Du xiulang touched his head and smiled to say the reason why they got together.

"Before that, we decided to talk to captain Sato and say hello. If we didn't call him at dinner, he would be angry with us."

As he said this, he put the lily in his hand next to officer Sato's vase. After a moment of silence, they got up and said goodbye to officer Sato and continued their party.

After the four members of the baseball team left, Bai yanzhenyu and others were also ready to continue to investigate in the alley. Unexpectedly, at this time, officer bainiao's mobile phone suddenly rang.
