"W-What ......?"

Listening to Takato's words, there was a faint speculation, and Matsumoto Kiyocho, Miwako Sato and others all looked very surprised.

And Gao Yuan continued:

"Since everyone here at that time speculated whether it would be the man who had a conflict with the deceased as the boss said, then the police must have also investigated the man at that time, after all, it is impossible to let go of any possibility of such a big thing as losing a gun. However, in the end, it was not the man who stole the gun.

"So, in this way, this gun theft incident is a 'complete crime' incident, isn't it?

"Being able to complete such a crime without leaving a single clue shows that the criminal who caused this incident is by no means simple, and this is certainly not something that ordinary people can do...... At the very least, it is impossible for ordinary people to do such a thing as stealing a pistol.

Moreover, apart from stealing the pistol, he did not use the stolen pistol to cause any other incident, which shows that the motive for stealing the pistol was not to do anything with the pistol, but more like some kind of ......

"Show off or something!

"- Look, I can take a pistol from the police and not be detected, isn't that a perfect crime?

"Probably, it's something like that.

"So, combined with the 'total crime' that the four people mentioned earlier talked about, I have a feeling that -

"Could this be an experiment done by one of them in order to verify the feasibility of 'complete crime'?"

In this way, listening to Takato's words, Matsumoto Kiyocho, as well as Miwako Sato and Takaki Watabu, all looked at Takato with shocked faces, and especially Matsumoto Kiyocho, Takato could already clearly feel the faint anger emanating from him-

I guess I was extremely angry at such a joking reason.

Gao Yuan thought so, and since he had already talked about it, Gao Yuan simply explained the whole thing completely at one time, and then went on directly:

"This behavior is not only a demonstration of one's own ability, but also a kind of ostentatious behavior, which should not be done by an older doctor or an associate professor.

"I think it's most likely that the student at the time, who is now an expert in criminal psychology, did it. Because of the talk of 'total crime', perhaps several people disagreed on this topic, and the young and vigorous Hirado Doji wanted to prove the feasibility of 'total crime', so he committed this gun theft incident.

However, after the rest of the people who played mahjong with him learned that he had done it, the older doctor and associate professor must have clearly known that his behavior was a crime, so they decisively took a stand with him, so after that, they never played mahjong together again.

And in this regard, in the face of their attitude towards their own behavior, and the fear that the two people who knew about their theft of the gun would be told about it, and they were afraid that it would affect their future, so Heidong Doji took the killing.

As for the lawyer, probably because he had just debuted at the time of the incident, there was a high probability that he did not take a decisive stand like those two, so he was not killed immediately at that time twenty years ago.

"But after five years, the lawyer may have experienced a lot, figured out something, and had a clear position on Ping Dong Tangji's behavior, the lawyer wanted to persuade him, but after five years, he was also killed by Ping Dong Tangji."

In this way, after roughly explaining the reason, listening to Takato's statement, Matsumoto Kiyocho couldn't help but fall into thought-

"So...... Will there be an interval of five years? First, an older doctor and an associate professor were killed 20 years ago, and then it took five years for the lawyer to be killed......"

At this moment, Matsumoto Kiyocho has already believed in the authenticity of Takato's conjecture, because it has explained too many details in the case very reasonably, as for-

"So, what is the whistle that the prisoner blows every time he commits an attack?"

This is something that the sacrificed Morimura police officer had been talking about before he died, and at this moment, Matsumoto Kiyocho still wanted to know this in the face of Takato, who had almost solved all the truth.

"Whistles?"

In this regard, listening to Matsumoto Kiyonaga's words, Takato thought about it and said:

"Is it the song "Let it be" that was popular in the mouth of the murderer when Officer Morimura heard the killer playing the popular song when he found the suspicious vehicle driven by the murderer and went to check it out?

"This is the last song before the British rock band 'The Beatles' disbanded. And it just so happens that 'The Beatles' is a four-piece band, and there are four people playing mahjong. Therefore, this song is very much in line with the sentimentality of the murderer Heidong Doji in the face of the players who were playing mahjong together so happily, but finally embarked on such a separate road, right? ”

In this way, Takato tried to analyze the details of this, which did not seem to be explained at the end of the original work.

In this regard, Matsumoto Kiyoshi couldn't help but nod his head in approval, feeling that the lofty analysis explained everything perfectly, and even this kind of detail was perfectly matched.

Then, the rest is just to wait for the third deceased lawyer and his child to confirm the other party's voice after the capture of Ping Dong Tangji.

At this time, Gao Yuan suddenly thought about it again, and tried to ask the owner of the mahjong parlor:

"That's right. Do you have any of the things they used to play mahjong here? ”

"Huh? It's been twenty years, how can there be ......?"

"Ahh Yes! ”

Just as Wataru Takagi felt impossible in the face of Takato's inquiry, the owner of the mahjong parlor answered directly, turned out a deck of mahjong tiles from under the counter, and said:

"This is the mahjong tiles they used to play mahjong back then, but because after they quarreled with someone, several of the cards in it were broken, so they couldn't be used. But because it was a card they had used, they never wanted to throw it. ”

"So, that means there's the fingerprints of those four people on it, right?"

Seeing this, Gao Yuan recalled the details of this original work, and tried to ask for this physical evidence.

And in this regard, seeing that the owner of the mahjong parlor kept such a key evidence, several policemen present couldn't help but look at each other a little -

Unexpectedly, such physical evidence can still be left!

So, in this way, when Officer Twilight and Officer Shiratori arrested Heidong Doji, with the fingerprints on the mahjong card and the identification of the third deceased's child through the voice, it was confirmed that Heido Doji was the serial murderer back then, and the incident was resolved before the end of the prosecution period.

So—

"After reasoning, start closing the case"

"Case Closure Evaluation: B"

"Knowledge: S"

"Logic: B"

"Social: C"

"After the settlement is completed, the overall score reaches B, and the reward is 30."

"Detective Rating: Certified Detective"

[Bounty: 2300]

The settlement panel appeared again, although because it was the original case, I couldn't get any high marks in the process of solving the case like copying the answers, but at least the bounty was still rising-

Perhaps, should I solve more cases like this, and find a way to accumulate more bounties, so that I can use the "world" with confidence to try to explore some of the truths I want to know, instead of taking risks in reality...... (End of chapter)
