"The deceased is named Miyamoto Sanae. Her father is a senior executive of a nearby company and her mother is a full-time housewife. She is an only child and has no brothers or sisters.
The deceased was good at sports and joined the school's tennis club. He had outstanding abilities and had always been a recognized core member of the club. He also had outstanding performances in youth tennis competitions in the city and won many awards in various extracurricular competitions.
His interpersonal relationships in school are similar to those of the previous deceased, Kanda Akina. Although he seems to have many admirers, he has never been involved in related disputes. He is a good student with both good character and good academic performance.
In addition, according to our investigation, the two deceased, Akina Kanda and Sanae Miyamoto, did not know each other before entering this high school, and there had never been any form of intersection between the two. "
"What about the cause of death?"
"Just like Akina Kanda, both were killed by poisoning caused by the murderer putting aconite powder in their lunch boxes. The method was exactly the same."
Having said that, the detective added another sentence.
"By the way, Mr. Shirakawa, we have previously asked the parents of the two deceased. The lunch boxes they ate today were all prepared by their parents at home and brought to school..."
The meaning of the detective's words is very clear. The two victims were from different classes, and their lunch boxes were prepared by their family members. Therefore, it is unlikely that they were poisoned at the same time by the same murderer.
Therefore, it is very likely that there is more than one murderer.
This case may be two different crimes committed by two murderers at the same time by coincidence.
“It’s too early to decide.”
The boy didn't comment. He withdrew his gaze and slowly pulled the curtain closed.
“However, in a place like a school, it is indeed not easy to poison someone’s lunch box without being noticed by anyone.
Especially the school's lunch rules, all students eat lunch in their own classrooms, at their own seats. Under such circumstances, unless the murderer and the victim were from the same class, it would be difficult to complete the act of poisoning. "
Having said that, the boy turned around. He first glanced at Xiao Wuwan, then looked at the detective next to him and ordered:
"Take the lunch boxes of the two deceased back to collect fingerprints. At the same time, apply for an investigation order from the superiors in my name, allowing the police to collect fingerprint information of all teachers and students in this grade."
Due to the relationship with the Hatoyama family, the boy’s name has always been very “useful” in the Metropolitan Police Department. As long as the application is submitted with a boy’s name, the Metropolitan Police Department will process it as quickly as possible.
In Japan at that time, any search operation of this magnitude required applying for an investigation warrant from superiors. Although the boy had some privileges in this regard, he had no intention of breaking the rules unless it was an extreme situation.
"Yes." The detective nodded and quickly wrote it down.
"Also, carefully investigate the interpersonal relationships of the two deceased in school, whether in class or in the club. If you find anyone who has a conflict with the deceased, or who has a relationship with both deceased, notify me immediately."
Different from the detective's previous guess of "two murderers, two cases", the boy seemed more inclined to believe that this was a case where one murderer used some special method to kill two victims at the same time.
"Yes."
The detective nodded, wrote these down again, and seeing that the boy had nothing else to order, he quickly left the infirmary.
As the door closed gently, the infirmary finally became quiet, and the boy looked again at Karasuma, who was sitting beside Akina's bed.
Just like when he first came in, little Karasuma was still sitting there blankly, looking down at his former good friend, as if he had lost his soul.
Seeing her like this, the boy hesitated for a while, but finally walked up to her and patted her shoulder gently.
"time to go."
Kokarasuma ignored him and seemed to have no reaction to his words.
The boy was silent again, and then he spoke again:
"She's dead now. We should go back."
Instantly, these words seemed to have irritated Xiao Wuwan's nerves.
"Go away!" She finally reacted, but she looked up and glared at the boy fiercely, and shouted with red eyes: "If you want to leave, go by yourself! You cold-blooded block of wood! I want, I want..."
Xiao Wuhuan couldn't say any more after she finished speaking halfway, because she saw that when she said the word "cold-blooded", there was a moment of obvious daze on the boy's face.
In just that instant, she realized that she had said the wrong thing on impulse.
How could she say such a thing just now?
The word "cold-blooded" may be used by other people who don't know the boy, but she can't. This is not only because she is one of the few people who truly understand the boy, but also because the boy once risked his life to save her. He is not cold-blooded at all...
"me……"
The nameless fire that had come from nowhere in his heart quickly dissipated at this moment. Xiao Wuwan was like a child who had done something wrong. He was at a loss and looked at the boy with some fear.
What Xiao Wuwan was afraid of was not that the boy would get angry and hit her, but that the boy would be disappointed in her and distance himself from her...
However, the boy did not show any displeasure. After a brief moment of daze, he just sighed softly and advised again with a helpless and sad look:
"The dead cannot be resurrected. Instead of sitting here meaninglessly, why don't we find a way to find the murderer who poisoned Akina-san together?"
He is always like this, showing almost unlimited tolerance to the people around him. Even though he is the one who is hurt, he still comforts her in return.
Chapter 650 I was used
At almost the same time on the same day, two poisoning cases occurred in the high school where Kogumaru attended.
One of the dead was Akina Kanda, a classmate and good friend of Kokarasuma at school, and the other was Sanae Miyamoto, who was in another class in the same grade.
The two victims were poisoned in exactly the same way: they were poisoned with ground aconite powder placed in their lunch boxes.
Considering the special lunch system of this high school, the difficulty of this continuous poisoning is undoubtedly very high.
The boy had already prepared himself mentally for another difficult case, but what he never expected was that the case would be solved just the next day?
Just early the next morning, the Metropolitan Police Department received a call from a person who had surrendered himself to the police. The middle-aged man on the other end of the phone stated that his daughter was one of the criminals who poisoned the two female students.
The boy in charge of the case rejected the middle-aged man's proposal to bring his daughter to the Metropolitan Police Department for interrogation, and instead took the initiative to visit her.
The reason was simple. He had promised Kokarasuma yesterday that he would let her join the investigation this time. If the suspect was asked to come to the Metropolitan Police Department for interrogation, Kokarasuma could not participate in it according to the rules and regulations. But if he visited personally, it could be avoided to a certain extent.
"Lu Zi, no matter what, you must explain it clearly to the police officer. Don't hide anything. Try to get leniency. Do you understand?"
In the living room of the house, a middle-aged couple left these words and temporarily went to the bedroom.
At this moment, on the sofa in the living room, opposite the boy, Kokarasuma and the two accompanying detectives, was sitting a high school girl in school uniform.
The female high school student had long, slightly curly hair and a pretty face, but her face was pale and she kept her head down, as if she didn't dare to look at the people sitting opposite her.
"What's your name?" the boy asked. Behind him, a criminal policeman opened the notebook in his hand.
Kuwai Michiko is a student in Class E of the second year..." the female high school student replied in a low voice.
Class E is the class where the second victim yesterday, Sanae Miyamoto, was in, while Akina Kanda and Kokarasuma were in Class A.
"Your father said that you poisoned Miyamoto's lunch box?"
"Yes... No, it's not!" Kuwai Michiko nodded subconsciously, but immediately shook her head violently and shouted excitedly:
"I, I didn't know there was poison in it! I thought it was just a laxative!"
Her words made the boy keenly aware of something unusual.
"Tell me everything you've been through first."
"Yes... yes!" Kuwai Michiko, who was already like a frightened bird, nodded repeatedly and said:
"It all started the day before yesterday. When I entered the teaching building to change my shoes that morning, I found someone had stuffed a letter into my indoor shoes. The words on the envelope were very ugly, and the recipient was me..."
Having said this, Kuwai Michiko quickly took out a folded piece of letter from her pocket and handed it to the boy.
The boy took it and looked at it. The handwriting was indeed ugly and crooked, as if the writer had deliberately written it with his non-dominant hand.
As for the content of the letter...
[I know that Akina Kanda from Class A is your competitor. If you don't want her to be selected for the Fall Drama Festival tomorrow, make a deal with me.]
[It will be difficult for me to participate in the next regional tennis tournament because of your E-class girl Miyamoto Sanae. If you add something to Miyamoto Sanae's lunch box tomorrow, I promise that I will do the same to Kanda Akina.]
[What you need to add is a strong laxative that can last for 24 hours. It is not life-threatening. You can take advantage of your class E's physical education class tomorrow morning to do it. Be careful to add it into the sauce as much as possible, otherwise it will be discovered. ]
[If you have this idea, then as a signal, use your utility knife to make a vertical cut on the lid of your shoe cabinet, and I will put the laxative in your shoe cabinet before tomorrow.]
[Don't ever try to contact me. If you do, the deal between us will be permanently cancelled. Also, remember to deal with this note.]
After reading the crooked letter, the boy handed it to Xiao Wuwan and the two detectives beside him. He thought for a moment and asked:
"What about the fall drama festival and regional tennis tournament mentioned in the letter?"
"These two events are competitions that our school often participates in. Since Akina Kanda from Class A is very good, she is the heroine of every drama festival. The main force of the regional tennis competition has always been Sanae Miyamoto from Class E..."
“Is the candidate chosen internally?”
"No, no! But it's almost the same..." Kuwai Michiko lowered her head and said, "Because they are so good, everyone will vote for them every time when choosing the contestants. Others don't have a chance at all, so it's actually no different from being selected internally..."
"Were the selections for both events originally scheduled to take place yesterday?"
"Well, it was originally supposed to be yesterday..."
Then both of them were poisoned to death.
"Are you in the drama club too?"
"Well...but as long as there is a drama show with Akina Kanda, I can only play the second female lead..."
If what Kuwai Michiko said was true, and this letter with crooked handwriting was also real, then the current situation was very clear.
The two victims who were poisoned yesterday were both envied by other students because of their outstanding abilities.
Among them, Akina Kanda from Class A corresponds to Michiko Kuwai from Class E.
According to Michiko Kuwai, the heroine of this year's Autumn Drama Festival must be Akina Kanda. This makes Michiko Kuwai, who is also a member of the drama club but has always been inferior to Akina Kanda, quite jealous.
So, when the mysterious letter appeared in her shoe cabinet, Kuwai Michiko was tempted.
After all, according to the description in the letter, this is not something that harms the world. It is just some laxatives that will cause diarrhea and prevent them from participating in the selection of candidates the next day. It is not a poison that can kill people...
According to the letter, as long as Michiko Kuwai administered laxatives to her classmate Sanae Miyamoto, the writer would do the same to her rival Akina Kanda.
But what Kuwai Michiko never expected was that the person who wrote the letter had deceived her. The medicine was not a laxative at all, but aconite powder that could cause death.
Therefore, Miyamoto Sanae, who was "forced to kill," was completely panicked. When she returned home yesterday, her parents noticed something was wrong with her. After some questioning, her parents called the police to report the case...
Chapter 651 I am the one being used
"Do you have any guesses about who wrote this letter to you?"
In the living room, the boy looked at Kuaijing Luzi, who had kept his head down and didn't dare to look at him, and asked.
"Yes, yes! It's Kida Airi!" Kuwai Michiko replied immediately.
Upon hearing the name, Kogumaru was stunned for a moment, and the detective next to him immediately wrote it down.
