It is said that this tape was recorded by Minegishi Mifuyu on her birthday when Noriko Kawai was in junior high school.
This tape has been treasured and preserved by Minegishi Mifuyu. The tape contains not only Minegishi Mifuyu's own voice, but also the voice of Noriko Kawai.
After obtaining this tape from the old house of the Minegishi family, our Detective Narisawa privately compared the voices of the two people on the tape with the current voice of Yamato Mifuyu.
The test results show that the voiceprint of Minegishi Mifuyu in the tape is very different from the voiceprint of Yamato Mifuyu today, and are completely different.
On the contrary, the voiceprints of Noriko Kawai and Mifuyu Yamato are almost identical, with no difference. "
Like fingerprints and tooth marks, voiceprints are also a unique mark of a person, and everyone's voiceprint is different.
Even if you can use voice changing techniques to change your voice, the voiceprint hidden deepest in your voice cannot be changed.
Unless major surgery is performed on the vocal cords.
It's like burning a fingerprint with flame, fundamentally changing it.
"No wonder you guys wanted to stage that poisoning scene, with the poison injuring the throat... So you wanted to use it to perform surgery on Yamatoda Mifuyu's voice?"
Vermouth only now understood that the real purpose of the poisoning of Yamato Mito in the news broadcast two days ago was here...
Upon hearing this, Bai Heqing shrugged slightly and made a helpless expression.
"It's my fault. Technology has advanced so fast in recent years that all kinds of incredible testing methods have emerged, such as DNA, fingerprints, tooth marks, voiceprints, etc.
It is much easier to confirm a person's identity now than before. It's not like when we were...
Such good conditions have produced a lot of useless people in the police force. I really admire this. I can only say that since Mr. Hatoyama retired..."
At this point, Bai Heqing's voice suddenly stopped. He seemed to have said something that should not be said, and he suddenly woke up.
He didn't say anything else, but turned to look out the window with a gloomy expression and a cold aura slowly emanating from him.
For a moment, the atmosphere in the car dropped to freezing point.
Vermouth glanced at him, as if wanting to break the weird atmosphere, and continued what he had said before.
"Isn't it convenient for us that they are so incompetent?"
"Oh, yes……"
Bai Heqing did not look at her. His eyes were still looking out the car window with a deep gaze.
"It does make things convenient for us, but I don't know if these idiots are worthy of their duties..."
His words were somewhat irrelevant, and Vermouth didn't know how to respond.
"By the way, where's that Kawai-sama? Where did you take her?"
Chapter 134 Wow, Rum again!
Takasugi Yuto is dead.
Under the leadership of Takagi Wataru, Conan and Mouri Kogoro came to the seminar room in the law school building.
Because the police had only just arrived, the scene had not yet been fully investigated and recorded, so everything in the room remained the same as it was when the police arrived.
Entering the seminar room, there was a closed window on the wall opposite the door, and the curtains were drawn, making the room a little dim.
In the center of the room, there was a small glass coffee table only at knee height. On the coffee table was a small bottle with a nozzle. Conan glanced at the trademark on the bottle. It was the kind of oxygen cylinder sold in shops outside.
This type of oxygen cylinder is very common and can be seen in general sports competitions. The bottle is filled with compressed oxygen, which can be sprayed out by pressing a button on the bottle.
Behind the coffee table is a short, low sofa.
On the sofa, there was a yellow-haired young man lying flat on the sofa. His face looked very peaceful and he was not wearing any shoes. He looked as if he had just fallen asleep leaning on the sofa. There was nothing unusual about him at all.
This person is Yuto Takasugi, the victim who died of suffocation in an extremely strange posture according to Officer Takagi.
"It certainly doesn't look like he died of suffocation..."
Kogoro Mouri put his hands in his pockets, bent down and carefully observed Takasugi Yuto who had a peaceful face as if he was sleeping, and murmured.
"This is the first time I've seen someone suffocate to death so peacefully... Takagi-kun, how many people are usually in this seminar room?"
"In addition to the deceased, there were three other people, namely the deceased's mentor and two classmates from the same department." Takagi Shigeru replied.
"Who was the first person to discover it?"
"She is the deceased's classmate, her name is Suzumura Rin, and she is said to be the deceased's girlfriend... Oh, and Himuro Takashi, he is also the first person to discover the matter, just like Suzumura Rin."
"Himuro Takashi?" Kogoro Mori turned and looked at him.
"Well, Mr. Himuro was a cleaner at Teitan University. When Suzumura Rin found the victim murdered, he was cleaning the air conditioner in the corridor. It was he who called for an ambulance and the police at that time," explained Takagi Wataru.
It was lunch time when Takasugi Yuto was killed. Most of the college students were eating in the cafeteria, and the other three people in the seminar room were no exception.
Among them, Suzumura Rin seemed to have left the cafeteria early and returned to the teaching building in order to bring lunch for Takasugi Yuto.
She was also the first person to discover that Takasugi Yuto had been murdered. Her screams attracted the cleaner Takashi Himuro who was cleaning the air conditioner in the nearby corridor. Takashi Himuro then rushed over and immediately called the police and an ambulance.
This is roughly what happened when the crime occurred.
"Where are these people now?" asked Kogoro Mouri.
"I have gathered them all into the associate professor's room next door. They are all there now."
While Kogoro Mori and Wataru Takagi were talking, Conan quickly observed the entire seminar room.
The windows and curtains were closed, making it impossible to see what was going on inside the room from the outside.
In the center of the room was the sofa where Takasugi Yuto was lying and the low coffee table.
On the other side, against the wall, there are three sets of tables and chairs placed in a row. It seems that they should belong to the three college students in this seminar room.
Among the three sets of tables and chairs, two of them were relatively clean and tidy, but the other one was very messy, with a lot of garbage sealed in plastic bags piled under the table.
Thanks to all the garbage, there was a strange, faint smell in the whole room.
"Let's go to the associate professor's office first to find out the specific situation..."
Not being able to see anything from the scene, Kogoro Mori said to Takagi Wataru.
"it is good."
Taking Kogoro Mori with him, Takagi Wataru opened another door in the seminar room and walked directly to the associate professor's office next door.
"So these two rooms are connected?"
Slightly unexpectedly, Mori and the other two followed Takagi Wataru to the associate professor's office next door.
There were three people sitting in the room, two men and one woman.
The woman wearing glasses and a necklace, who looked gentle, was the first person to discover the case, Suzumura Rin, the girlfriend of the deceased, Takasugi Yuto.
The middle-aged man next to her with stubble, who looked to be in his thirties, was called Kunimatsu Shogo, an associate professor, the director of the seminar, and also the mentor of these people.
The last one is Meguroto, a young man with the same blond hair as Takasugi Yuto, dressed casually and looking like a street urchin. He is also a college student in this seminar room.
"Officer Takagi, where is Mr. Himuro?" Conan asked.
Everyone in the seminar room is here now, but according to what Takagi Wataru just said, there should be a cleaner named Himuro Takashi who is also involved in this incident.
"Oh, Mr. Himuro has been applying to the school to suspend his business recently. He just went to the principal's office and will be back soon..." explained Takagi Shigeru.
After briefly understanding the identities of several people in the room, under the arrangement of Takagi Wataru, Maori Kogoro began one-on-one questioning of these people.
"Hello, Meguroto-san."
After asking Suzumura Rin and Kunimatsu Shogo to temporarily go to the seminar room next door, accompanied by Takagi Wataru, Maori Kogoro gave a kind smile to the yellow-haired Meguro.
"Hello! Please give me your guidance!"
Meguro seemed very nervous. He glanced at Maori Kogoro and Takagi Wataru beside him with some uneasiness, and asked tentatively:
"Um, officer, are you suspicious of me?"
"Don't worry, it hasn't gotten to that point yet. It's just that we don't have enough information right now, so we wanted to ask you some questions individually."
The one who answered him was Kogoro Mori.
"Okay, Meguro-kun, may I ask what is your relationship with the deceased Takasugi Yuto?"
"Uh, well, we're just ordinary friends who have a good relationship. We used to go out together to drink and play games..."
"before?"
"Yes, yes, since Yuto asked for leave to work part-time at Narisawa Detective Agency, we haven't been getting along well..."
"Does that mean we'll quarrel?"
"no!"
Meguroto immediately denied it and said excitedly: "We didn't quarrel! It's just that he often refuses me when I ask him to go out and play!
And, he didn’t even pay back the money he lent him…”
"Borrow money?"
Upon hearing this, Maori Kogoro hurriedly asked, "Are you saying that the deceased had borrowed money from you before?"
"Yes, I borrowed it several times this semester, and never returned it..."
"its not right……"
After hearing what he said, Maori Kogoro frowned immediately.
"The deceased should be relatively well-off, right? He told me yesterday that someone at school stole 100,000 yuan from him, and asked me to help him catch the thief..."
"Mr. Maori, so this is true?" Takagi Wataru asked in surprise.
"Well, to be honest, I came to Teitan University today just to handle this commission."
"impossible!"
After hearing what Maori Kogoro said, Meguro shouted:
"Don't I know that Yudou guy well? He has always been a spendthrift! Not to mention 100,000 yuan, he can't even save 50,000 yuan! It's absolutely impossible!
Besides, he borrowed money from me two days ago when he just returned to school. Where did he get 100,000 yuan for someone to steal?"
[If Meguroto didn't lie, then Takasugi Yuto lied and wanted to trick his uncle into coming to school? ]
After hearing what Meguroto said, Conan fell into deep thought.
"Ahem! We'll talk about things that are not related to the case later."
