On the vault floor of Miwa City Bank, Gao Yuan was a little curious when he heard what Mouri Kogoro said.
"Who is Miss Mayuko?"
After all, when he first entered the vice president's office, Mouri Kogoro said: Mayuko asked him to come. But now the person suspected of being Mayuko is lying in the vault without knowing whether he is alive or dead. It is really strange.
"She is a teacher at Xiaolan Computer Training School and also my drinking buddy. I know nothing else."
Kogoro said.
"Computer training school is a subsidiary of our group."
Takeo Emoto echoed, "She also serves as a teacher there."
As he said that, Kogoro on the side dialed Mayuko's number with his mobile phone. Sure enough, the phone in the vault rang - "Sure enough, it's Mayuko's!"
Kogoro leaned on the door and shouted, "Miss Mayuko! Cheer up!"
Seeing this, Emoto Takeo also went up and shouted.
Gao Yuan ignored them, but looked at the piece of paper with warning words on the wall - that is to say, someone had changed the password of the vault and left such a piece of paper. The bank did not dare to call the police, so he called Maoli
The detective came over and found that there was someone lying in the vault that could not be opened!
"Speaking of which, why did you ask Mr. Mori to come here?"
Gao Yuan asked. Now that Mouri Kogoro is not famous yet, it is a bit strange that the bank would come to him for such a serious case.
"Oh, it's the Mori detective contacted by Miss Mayuko."
Takeo Emoto said, and Takato looked at Kogoro. Kogoro was stunned for a moment before explaining.
"It happened at noon today. At that time, I received a call from Mayuko, thinking that there was some social activity asking me to go. However, Mayuko told me seriously on the phone that she had encountered a very difficult matter now and wanted to go.
Discuss with me and tell me that you must not tell the police and ask me to come to the bank to find her."
With that said, Kogoro walked up to the piece of paper and said, "Now it seems that the unspeakable thing refers to this matter."
After listening, Gao Yuan thought for a moment.
"In other words, after discovering that the password of the vault was changed, was Miss Mayuko outside the vault?"
"Yes."
Takeo Emoto said, "After discussing with her, she invited Detective Mori to come over."
Gao Yuan carefully looked at the iron door structure of the vault and the keypad of the combination lock, and asked: "Is this door a computer-controlled automatic door?"
"Yes."
Takeo Emoto said.
"Then the only people who can change the password should be the bank's internal staff."
Gao Yuan said, after all, it is impossible for this kind of facility to be connected to the Internet.
"Who can enter the vault level?"
"Besides us, there are two security guards, and three other people."
Takeo Emoto said, so Takato and Kogoro asked Takeo Emoto to call these people.
Soon, five people arrived here. In addition to the two security guards, the other three were: general manager Yuzao Nimura, head of the vault Yoko Sakai, and corporate sales manager Ryosuke Hasegawa.
Kogoro looked around the five people with fierce eyes, then turned his back and said seriously: "The prisoner, who is..."
Before he finished speaking, Gao Yuan saw a dumbfounding scene: Yuzo Nimura, Yoko Sakai, and Ryosuke Hasegawa actually raised their hands at the same time!
Seeing Gao Yuan's surprised expression, Kogoro turned his head and looked at the three people with their hands raised, with a look of shock on his face: "You three, are you not a gang committing the crime?"
"no!"
The three of them said in unison, and then Yuzo Nimura stepped forward and said, "I did it alone."
"I did not do that!"
Jing Yangzi retorted.
"No! I am the criminal!"
Hasegawa Ryosuke also stepped forward and said.
"You guys, recruit them from the truth!"
Kogoro, who was stunned by the three people's unwillingness to admit guilt, shouted.
"I made a big mistake, even though I didn't intend to kill her!"
Nimura Yuzo said, and then was pushed away by Jing Yangzi.
"Her death was caused by me, and I was the one who killed her!"
Upon seeing this, Ryosuke Hasegawa immediately pulled over to Yoko and asked, "Why would you tell such a lie?"
"You are the one who lied."
Jing Yangzi asked, "It was indeed me who killed her."
Looking at this situation, Gao Yuan couldn't help but laugh: It's interesting. The life and death of the people inside are still unknown, but they also admitted to killing people, but no one said anything about changing the password.
"It's too late."
Jing Yangzi said, walking to the password keypad, "If you try to open this automatic door and alert the police, the bank will explode, and then the matter will really be irreversible!"
Gao Yuan smiled, pointed at the piece of paper, and asked: "Then, who posted this?"
As a result, the three of them shook their heads at the same time.
"Hey? Hey! Hey!"
Kogoro was surprised: "Why doesn't everyone admit it this time?"
"In that case, let's ask them separately first."
Gao Yuan said and asked Emoto Takeo to prepare three vacant rooms.
Gao Yuan first asked Nimura Yuzo, but before Gao Yuan asked much, he first confessed a piece of information.
"Actually, I have an ulterior relationship with Mayuko Sonoda."
"An affair?"
Gao Yuan asked tentatively.
"In the beginning, we made an appointment not to restrain each other. But recently, Mayuko said that she really couldn't bear it anymore. She forced me to divorce, otherwise she would tell my wife everything. At that time, I was dizzy. When I woke up,
Later, they discovered that I had strangled Mayuko to death."
Nimura Yuzo held his forehead and said with some regret, "I know this will happen one day, but if I don't do this, my family will be destroyed!"
But Gao Yuan frowned, "Where did you kill her?"
"It's in the vault, next to the desk."
Nimura Yuzo said.
"What happened to the vault door? It wasn't locked at the time?"
Gao Yuan asked, and Nimura Yuzo nodded.
Seeing this, Takato realized that he had thought the wrong question, and hurriedly asked Emoto Takeo, only to find out that when the password was changed, the door was actually open, but when Kogoro and Takato arrived, they saw that the door was locked.
It's an automatic door. Locking the door only requires program control.
On the other side, Kogoro was asking Jingyangzi, and Jingyangzi blurted out: "There are some bad rumors about that woman."
Kogoro was very surprised by this and immediately asked: "There are bad rumors about Mayuko?"
"Misappropriation of public funds without authorization! She took advantage of her job to embezzle public funds and took out the valuables kept in the safe without authorization, using them as collateral to raise funds for foreign exchange speculation. She would then take them out after the delivery date.
Put the items back, and the money earned will belong to you."
As he said this, Jing Yangzi suddenly burst into anger and looked very angry.
"What a joke! Nothing is so cheap, because this little girl is going to ruin my hard-earned career, so I have to let her surrender before the situation gets serious!"
Viciously, Jingyangzi said to Kogoro.
"Although you put all the responsibility on others, you might be fired for this, right?"
Kogoro was not intimidated by the opponent's aura, "So it seems impossible that you want to cover up all this, right?"
"I expected that she would come back today to return the misappropriated items, so I stopped her in the vault. As a result, I had an argument with her, and when I came to my senses, I had already strangled her to death."
Jing Yangzi said.
"Did you post that paper?"
Kogoro asked.
"No, but I don't think it's necessarily a mystery."
Jing Yangzi said, "She is an excellent system engineer. It is a piece of cake to hack into such a system. In addition, we don't know what she put in the safe. If we check it, there might be a bomb or something."
