Stay away from Conan

Especially when the owner of the mahjong parlor confirmed that the person Gao Yuan found was actually the student who played mahjong with the three deceased people twenty years ago. This proved that Gao Yuan had not found the wrong person.

Therefore, this situation made the police officers present particularly puzzled.

Among them, Officer Megure and several other police officers who had a lot of contact with Gao Yuan were able to accept the speed with which Gao Yuan came to a conclusion so quickly. Matsumoto Kiyonaga had formal direct contact with Gao Yuan on the investigation of the incident for the first time today. Therefore, he was not used to this kind of shock.

Therefore, facing the fact that Gao Yuan had found the identity of the suspect, Matsumoto Kiyonaga couldn't help but ask Gao Yuan, intending to find out why Gao Yuan could identify this target person so quickly——

"Mr. Mingzhi, how did you identify this person?"

Matsumoto Kiyonaga asked directly curiously, wanting to know why Gao Yuan could identify the candidate so quickly.

In this regard, Gao Yuan immediately gave an explanation:

"Twenty years ago, students could discuss case-related matters with doctors, associate professors, and lawyers, and eventually analyze the facts of the case. Don't you think this combination is interesting? Doctors can be responsible for forensic-related majors, The associate professor can demonstrate theoretical techniques, and there are lawyers in the legal field... It is not easy to think about the students who can join this group to chat together. It is possible that the major he studied is also conducive to solving cases, and he also works with this group. The other three are different.

"Secondly, this mahjong parlor is located near the homes of the three deceased people, so it is obvious that the student will come here for similar reasons. And the twenty-year-old student can come here every Saturday. It is probably not because of where he lives. Close, but the school he attended at that time was close to here. Therefore, taking this mahjong parlor as the center and drawing a circle with the farthest distance from the current three deceased's homes as the radius, there happens to be a university within the range. That university is very famous for its criminal psychology, so I guess that the student's major is probably that.

"Finally, the student who was in his early twenties at the time is almost in his early forties now. At this age, and because he was able to chat with three deceased people with such a big age gap, he must have good professional knowledge, so There is a high probability that if this student is engaged in this industry now, he should be well-known.

"So, based on the above analysis, we are most likely looking for someone who is in his early forties, graduated from that university, majored in criminal psychology, and is now somewhat well-known in the field. With such a range , it’s not difficult to lock in a suspected candidate.”

In this way, Gao Yuan briefly described the method of locking Pingdong Hall.

Everyone present was shocked by this. They felt that what Gao Yuan said was indeed reasonable. They didn't expect that the scope could be narrowed down so much.

After hearing this, the owner of the mahjong parlor couldn't help but nod, and exclaimed, as if he remembered something, and then said:

"Oh... I just remembered that, that student is indeed studying criminal psychology. Every time they talk about a case, he can always identify who the murderer is from the criminal's psychological point of view... like It’s ‘the prisoner is the husband who was specially interviewed’ or something like that…”

In response, Gao Yuan couldn't help but glance at the boss——

You should have thought of it earlier, and you would have had to find another reason to explain...

——That's right, Gao Yuan's so-called analysis process was actually made up casually. The actual situation is that because he knew the plot of the original work, he probably remembered the current appearance and occupation of the key student, and then found it from criminal psychology experts of the same age. Create a character who looks the same as the person in your impression and in the original work.

In this way, because he knew the answer directly, after having the answer, Gao Yuan used the answer to fabricate the process in reverse, which was naturally very simple.

In this way, if the boss had remembered earlier that the student majored in criminal psychology, the fabrication process would have been much simpler.

However, it’s not bad now——

"In short, now that we have found this person and asked the child of the third deceased to come over and confirm the voice, everything will become clear. After all, that child heard the prisoner's voice back then."

Gao Yuan said this.

"Well, Megumi..."

In this regard, listening to Gao Yuan's words, Matsumoto Kiyonaga also directly issued the order since he now had a clear goal.

Hearing this, Officer Megure next to him immediately responded, and then left the mahjong parlor with Officer Shiratori.

The rest, Sato Miwako and Takagi Wataru were left here, preparing to do some evidence collection work about this mahjong parlor.

In this way, Miwako Sato was curious about the progress of the current incident and Takato's remarks and asked:

"But...since that person had such a good relationship with the three of them back then, why do you think, Mr. Akechi, that he was the murderer? It's entirely possible that he was the person who had a conflict with the four of them back then, right?"

In response, Takagi Wataru nodded as if he had the same feeling.

Faced with such inquiries, Gao Yuan also gave an explanation:

"Remember the boss said that before they broke up, they talked about a 'complete crime'? I think the key to the problem should be related to this matter."

Saying this, with a calm expression, Gao Yuan looked at the mahjong parlor owner with some confidence and asked:

"Boss, after they talked about the 'complete crime' thing, did any strange events happen around here?"

"ah?"

When asked this question, the mahjong parlor owner couldn't help but look up and think, and then said in surprise:

"Ah! That said, I remembered that a long time ago, around the time you mentioned, there was an incident of a gun being lost near us. It was when the patrolman took away the gun while he was asleep, which caused There was a big commotion, but two days later, the guns were sent back, and nothing happened...

"However, everyone was speculating at that time that the person who did this should be the man who had a conflict with the four guests, because it was said that he had done a lot of bad things, so everyone wondered if this was the case. He did it too.”

"Yeah, I understand."

After listening to the boss give the answer he wanted, Gao Yuan nodded with a smile and affirmed:

"In this way, I think I probably understand the prisoner's reason..."

"What?"

They were confused again and couldn't figure out how Gao Yuan derived the reason for the murder from the boss's words just now. Matsumoto Kiyonaga and Sato Miwako were all confused.

Gao Yuan immediately explained:

"Because it's a 'complete crime'! The patrolman lost his gun, and even though it was returned in the end, from the beginning to the end, he never found out who did it. Isn't this a 'complete crime'?" ()
