Chapter 2 Chapter of Doubt Kyoichiro Kaga's Record

Regarding this case, one thing that caught my attention was that the murder weapon used by the suspect turned out to be a "paperweight", which was originally in Hidaka Kunihiko's house.Therefore, we can infer that when the suspect entered Hidaka's home, he had no intention of killing Hidaka Kunihiko.If he had planned to kill him from the beginning, he probably wouldn't have used such a method.Of course, we do not rule out that the murderer had made arrangements in advance, but due to temporary changes, he had to change the method of killing.However, after changing the method, it is too thoughtless to use the paperweight as the attack weapon.From this point of view, this crime should be classified as a sudden and impromptu murder, right?

However, there is one thing that cannot be ignored - the door of Hidaka's house is locked.According to the confession of the first discoverer, the door of the house and the door of Hidaka's studio were locked. Regarding this, Hidaka Rie once confirmed: "After five o'clock, I locked the door when I left the house. Because I was worried that my husband would be alone in the studio, and he would not know even if someone came in from outside. But I never dreamed that such a thing would actually happen.” According to the results of fingerprint comparison, only the fingerprints of the Hidaka couple were detected on the door handle of the gate, and there were no traces of wiping on the door lock.Judging from the fact that the door was locked, the door should have been locked since Hidaka Rie left.

The door of the studio was probably locked by the prisoner from the inside.Because it is different from the entrance door, there are obviously traces of fingerprints being wiped off here. Judging from the above points, the prisoner is most likely to climb into the room through the window.However, there is a contradiction in this inference: The gangster who had no intention of killing someone broke in through the window?But the possibility of him wanting to steal is very low.Even if it was the first time to visit Hidaka's house that day, he knew immediately that there was nothing of value left inside.

In fact, there is only one hypothesis to solve this contradiction: the prisoner went to Hidaka's house twice that day.When I came for the first time, it was indeed because I had something to visit.But after that person left Hidaka's house (to be correct, it should be after pretending to leave Hidaka's house), he immediately made a second visit.At this time, the man had made up his mind, so he entered through the window instead.Needless to say, this idea is naturally an "attempt to kill".We may well assume that his murderous urges had begun during his first visit. If this is the case, who had been to Hidaka's house on the day of the incident?The answer clearly points to two people: Fujio Miyako and Nonoguchi Osamu.

We launched a cross-investigation on the two men.However, the result was contrary to what the police thought, and both of them had alibi. On the same day, Miyako Fujio returned to her residence at six o'clock in the evening. Her fiancé Tadao Nakazuka and Kikuo Ueda, who acted as their wedding introducer, testified for her. They agreed to discuss the matter of holding an engagement ceremony next month.Ueda is Nakazuka's boss, and has no direct relationship with Miyako Fujio, so there should be no need for him to perjure his subordinate's fiancée.According to Hidaka Rie's testimony, it was already five o'clock when Miyako Fujio left Hidaka's house. Judging from the distance between Hidaka and Miyako's house and the traffic conditions between the two places, it is extremely reasonable for her to arrive home at six o'clock.In other words, Miyako Fujio's alibi was flawless.

Next is Nonoguchi Osamu. In scouting this man, it is undeniable that I took a certain amount of personal emotion.He was my predecessor in the workplace and someone who knew about my obscure past. However, in our line of work, if the handling of the case is affected due to personal grievances, it can only be said that it is incompetent.I made up my mind when I took on this case to look at our shared past as objectively as possible.However, this does not mean that I will forget the past, it may also become a sharp weapon to solve the case. According to Nonoguchi himself, his alibi read as follows:

At about 4:30 that day, after Miyako Fujio came to visit, he left Hidaka's house.Then he went straight home and worked until six o'clock.At six o'clock, Yukio Oshima, the editor of Boys Club, came, and they began to discuss the manuscript.During this period, Hidaka Kunihiko called and said that he had something to discuss with him, and asked him to come to his house at eight o'clock. Nonoguchi and Oshima had dinner at a restaurant near their house before going to Hidaka's house. It happened to be exactly eight o'clock when they arrived.He felt a little strange that no one answered the door, so he called Hidaka Rie.Before Hidaka Rie arrived, he went to the nearby coffee shop "Yoran" and waited for her while drinking coffee.At about 8:40, he turned back to Hidaka's house again, just as Hidaka Rie also came.The two entered the house together and found the body.

While sorting out the case, I found that Osamu Nonoguchi's alibi was almost perfect.Da Dao of Boys' Club and the owner of "Yang Deng" also proved that what he said was true. However, it's not completely without loopholes.Judging from his confession, his only chance to kill Hidaka should be before calling Rie.In other words, after he separated from Oshima, he killed Hidaka Kunihiko as soon as he arrived at Hidaka's house, and after doing some aftermath, he called the victim's wife as if nothing had happened. However, the forensic examination has proved that such a hypothesis cannot be established.On the afternoon of the incident, Kunihiko Hidaka and his wife ate a hamburger while shopping with his wife. According to the degree of digestion of the food in the stomach, the time of death should be between five and six o'clock, and it is impossible to exceed seven o'clock at the latest.

Is it only possible to admit that Nonoguchi's alibi is perfect? To be honest, I always thought he should be the suspect.The reason for this determination was because of a certain sentence he blurted out on the night of the incident.From the moment I heard that sentence, I began to wonder about the possibility that he was the murderer.I also know that it is very inefficient to handle cases based on intuition alone, but only this time, I let my intuition develop freely. I was very surprised to hear that Osamu Nonoguchi had recorded this incident.Because I think, if he is really the murderer, he will never do such a stupid thing as explaining the details of the matter clearly.However, when I read the notes, this idea changed 180 degrees.

I must admit that the notes were very well written and very convincing.When I was reading it, I almost forgot that what was described in it might not be true.However, isn't this exactly what Nonoguchi wanted? I wondered how, as a prisoner, he would divert the police's suspicion of him.He should have expected that because of the problem of time, he would become the most suspicious object. And what appeared in front of him at this moment was a man who had once coached in the same school.So he took advantage of the man and wrote fake notes for him to read.The rookie teacher in the past, even if he became a criminal policeman, he would definitely not be a great weapon. He should be easy to fall for.

Could this be my own cranky thinking?Because they knew each other, they subconsciously emphasized too much on handling the case without personal emotions, and ended up losing sight of the facts? However, I managed to spot several hidden pitfalls in his notes.What's even more ironic is that if it wasn't for this note written by him himself, there would be no important evidence that other than him, the prisoner didn't think second. The obstacle now is his alibi.However, having said that, it was just his personal explanation from beginning to end.Was the call received after six o'clock really from Hidaka Kunihiko?No one knows this. I reviewed the many doubts related to this case from beginning to end, and found that there is a clue to all these, and the answer lies in Nonoguchi Osamu's notes. After re-examining my reasoning, I reported it to my supervisor.My supervisor is a very cautious man, but he agrees with me.Judging from the impression of the first meeting, he also felt that Nonoguchi was weird.Nonoguchi's notes do not mention that he was unusually excited and talkative on the night of the incident.Both my supervisor and I know that this is one of the typical cases where the real culprit shows his face. "Now all we need is physical evidence," said the supervisor. I also feel the same about this.Although I am quite confident in my reasoning, it can only be regarded as a reasonable inference based on the current situation. There is another problem.What is the motive of the criminal?We did all kinds of investigations, not to mention Kunihiko Hidaka, and we also collected a lot of information on Osamu Nonoguchi, but we couldn't find a reason for Osamu Nonoguchi to kill Hidaka.No, Hidaka can even be regarded as Nonoguchi Osamu's benefactor in terms of caring for him at work. I recalled Osamu Nonoguchi in my memory. He was always calm when he was teaching in a junior high school, and he followed the scriptures in everything, and never made a mistake.Even if the students cause any trouble temporarily, he will never mess up his position. He will refer to past cases and make the most non-controversial decision at the first time.To put it bluntly, he won't add any personal emotion, everything is business-like.A female English teacher once talked to me about this characteristic of him: "Ms. Nonoguchi really doesn't like the job of teaching. Because he doesn't want to trouble the students, and he doesn't want to take on extra responsibilities, so he Handle everything as calmly as possible." She said Mr. Nonoguchi wanted to quit teaching early to become a writer.Even the fellowship among teachers is rarely attended, and it seems that they are all writing at home. As a result, as she said, Nonoguchi Xiuzhen became a writer.I don't know what the profession of teaching means to Nonoguchi.However, he once said to me personally: "The relationship between teacher and student is based on an illusion. The teacher mistakenly thinks that he can teach the students, and the students mistakenly think that they can learn from the teacher. The important thing is Well, it is a happy thing for both parties to maintain this illusion. Because seeing the truth clearly, it will not benefit at all. What we are doing is just playing tricks on education." What kind of experience made him say such a thing?I do not understand.
