Stay away from Conan.

"drink wine?"

Hearing this, although it was indeed Saturday night, things were different from what Gao Yuan analyzed. For this reason, Matsumoto Kiyonaga couldn't help but look at Gao Yuan, wanting to see what he thought.

In response to this, Gao Yuan did not change his expression, but asked:
"Then have you ever asked the deceased what he said after he came back from drinking?"

Hearing this, Officer Memu nodded and said:

"Yes. It is understood that when the deceased came back drunk once, he muttered:

"'Damn! That guy kept calling me a crybaby! He laughed at me all the time.'

"Therefore, the wife of the deceased guessed that the person who often drank with the deceased should be an old friend of the deceased who grew up playing together. Therefore, she did not find anything related to mahjong..."

While Officer Memu was speaking regretfully, Gao Yuan suddenly corrected him:
"'Crybaby (crying bug)', which is also called 'Ming worm', has the same pronunciation, and 'Ming' is the 'Ming tile' in mahjong."

For a moment, when they heard Takato specifically pointed out that there might be some ambiguity in the words, causing the meaning of the deceased's wife to completely change when she relayed it, the expressions of Officer Megure and Matsumoto Kiyonaga suddenly changed——

In this case, the connection between Mahjong cannot be an accident!

Just as he was thinking this, Officer Megure's cell phone rang at this moment. Takagi Wataru called just at this moment and began to report the news they had received after questioning the family of the second victim.

So, just in time, Officer Megure simply turned on the speakerphone of his mobile phone, and asked Takato and Matsumoto Kiyoshi to talk directly to Takagi Wataru——

"That's right, we learned from the brother of the second deceased, Mr. Wheatfield, that he had heard the deceased's wife clearly say that the deceased often stayed up all night on Saturday nights and would not come home until the next morning. just came back.

"The deceased's brother still remembers that the deceased's wife thought that the deceased was having an affair and stayed out all night. Therefore, after the deceased went out, the deceased's wife kept sending messages to the deceased's pager to disturb him. As a result, the deceased became very angry at that time. He called home from an unknown phone number and yelled at the wife of the deceased:

"'I'm seeing a doctor right now, leave me alone!' Something like that."

"'See a doctor (I SHI YA I TSU TE N)'? Haha, did you hear it wrong? It should be 'Always listen', right? It's only one card away from being fooled, that's why you're angry because you were disturbed Just call home!"

Gao Yuan was very direct and once again pointed out the misunderstood parts of his words.

Immediately, after hearing this, Matsumoto Kiyonaga knew that Takato's analysis was most likely correct. The three consecutive deceased people all went out on Saturday night and were familiar with mahjong terminology, so he immediately turned to Takagi on the other end of the phone. She said:

"Okay! In that case, you should join Shiratori and the others immediately and investigate the mahjong parlor near the three deceased's homes to see if you can find the mahjong parlor where the deceased played mahjong together!"

Immediately, hearing the energetic momentum of Chief Matsumoto, Takagi Wataru on the other end of the phone and Sato Miwako who was with him also immediately responded. After hanging up the phone, they also enthusiastically joined in the investigation of the mahjong parlor. Under investigation.

And soon, Officer Shiratori found a key clue in a mahjong parlor called "Sparrow"——

According to the owner of the mahjong parlor, the three deceased people often played mahjong in his mahjong parlor a long time ago. In addition to these three people, the person who played mahjong with them was a student who was only about 20 years old at the time.

For a moment, after learning the news, Matsumoto Kiyonaga couldn't sit still at all, and planned to go directly to the scene to participate in the investigation, and Officer Megure also went there naturally.

Seeing this, Gao Yuan had no reason to stay alone in the Metropolitan Police Department. After getting into the car arranged by Officer Memu, he also followed him to the mahjong parlor...

……

"Do you really not know that student's name?"

Arriving at the mahjong parlor, Shiratori Rensaburo, Sato Miwako, and Takagi Wataru were surrounding the owner of the mahjong parlor, trying their best to learn from him the story of the student who played mahjong with the three deceased people. identity--

Because, according to Gao Yuan's inference, the serial murderer is most likely the fourth person who played mahjong with them and is still alive!

But in this regard, the owner of the mahjong parlor really didn’t know the name of the student.

Seeing this, Gao Yuan, Matsumoto Kiyonaga and others arrived later. After learning about the current situation, Matsumoto Kiyonaga couldn't help but wonder:

"You don't know...why you are so impressed by these people?" In this regard, the boss gave an explanation——

Because the combination of their table is very interesting.

A doctor, an associate professor of science and engineering, a new lawyer, and a college student.

Despite their age differences, the four of them got along very well. When they played mahjong, they would often reason about real-life cases together.

For this reason, mahjong parlor owners who never read newspapers or news will always buy news reports about the cases they talk about to see the results, and the results analyzed by the four people will always be compared with the last The reports matched reality, so the boss was very impressed with them.

However, after they stopped coming here, the boss didn't watch the news much, so he didn't know the facts of the three deaths.

According to the boss's deeper recollection, the boss remembered that before they came, they had talked about the topic of "complete crime", and several people broke up. After that, except for the student who occasionally came back here, Apart from that, the other three were never seen again.

In this regard, faced with such a result, although the information is limited, compared with the situation in the previous 20 years when there was no clue, Matsumoto Kiyonaga already feels extremely lucky——

Although it is still a needle in a haystack, as long as there are clues, the rest depends on the police investigation.

At the same time, the owner of the mahjong parlor also provided some clues. For example, there were often customers who were critical of their reasoning, and that person had also had conflicts with them and threatened to kill them.

Therefore, Matsumoto Kiyonaga and others speculated that in this case, there might be another criminal.

"Thank you for your hard work, Mr. Akechi!"

Regarding the fact that the situation has progressed to this point within a few hours, Matsumoto Kiyonaga is really impressed by Gao Yuan.

"Then it's our job."

Officer Memu couldn't help but said with certainty:

"Relying on reasoning to reach this point is the limit, right? With limited clues, it is up to our police to determine the identities of those people at that time!"

Saying this, Officer Memu was also full of energy.

However, facing the attitudes of several people, Gao Yuan took out his mobile phone with a look of helplessness, pointed to the identity information of a person found on the Internet and said to the mahjong parlor owner:

"Boss, I think that student back then must be this person!"

Immediately, after hearing this, Officer Memu and others looked shocked and a little unbelievable.

After listening to Gao Yuan's words, the boss carefully observed the photo, and then said immediately:

"That's right! It's him! He's the student back then!"

So, after hearing the answer, Matsumoto Kiyonaga couldn't help but ask:
"Mr. Wise, this..."

"A decent criminal psychologist. This is a photo of him from 20 years ago."

Simply, Gao Yuan explained:

"If what I expected is correct, this is the murderer!"

For a moment, after hearing this, all the police officers looked at each other——

How did he identify the prisoner so quickly? (End of chapter)
