"Letitbe......" Administrator Matsumoto walked into the room, perhaps a little relieved by the news of the prisoner again, and took the initiative to say to the crowd, "I didn't expect it to appear at such a time......

"Alert!"

"Okay, Sato and Chiba, you go to the neighborhood to investigate, Shiratori 'copys' around the death message, and re-investigate Mr. Hirato's circle of friends!"

Managing Officer Matsumoto looked stern, and ordered seriously: "Takagi, go and meet the bereaved families of the three previous victims, and find out if Mr. Heping Dong can be contacted!" ”

"Yes! Understand!! ”

Takagi saluted energetically and ran out of the door, seeing that Gao Cheng was stunned, and hurriedly said to Manager Matsumoto: "Police, can you lend Officer Sato to me first?" ”

"Huh?"

The Matsumoto manager seemed to be a little distracted when he looked at the figure of Takagi leaving, and it took a while to react and look at Takasei: "Detective Joto has a clue?" ”

"I just think there are some places that deserve an in-depth investigation, and with Officer Sato, who knows a lot about this serial murder case, it is more convenient to investigate."

Gao Cheng actually wanted to pull Takagi away, but this guy ran away as if he had been doped.

"What does Detective Joto think is wrong?" Matsumoto's gaze was slightly condensed, and the scar that crossed his left eye was imposing.

“Letitbe…… The fans of the Beatles all thought that the lyricist had written his feelings of not wanting the band to disband into the song," Gao Cheng said calmly, "I have been wondering if the prisoner will have a special meaning when he puts this lyric on his lips, so I specially checked it, the murderer in this case is probably not a random killing, and the victim and the prisoner are companions." ”

Matsumoto's face remained unchanged, but his eyes darkened slightly.

"Twenty years ago, Morimura did say that when he was close to the vehicle to investigate, he heard the other party humming this song, and hummed it while shedding tears......"

"Tears?"

"Yes, the forest cares about this song until death, and I've been wondering what special meaning this song has over the years, but the few people who were killed, whether it was age, occupation or life, had nothing to do with it......"

Matsumoto's gaze at Gao Cheng finally changed, as if he had thought of something, and continued to say in a deep voice: "This case is up to you, maybe this time it can really be completely solved...... However, I also hope that you will not let your guard down. ”

Matsumoto patted Gao Cheng on the shoulder, turned to Sato and said cautiously: "Morimura will get married next month after the accident, in order to make another contribution in front of the woman who is about to become his wife, I didn't wait for us to be hit by the suspect's car in an impetuous way, I don't want this kind of thing to happen to everyone......"

"Yes, probably not, right?"

Gao Cheng's cheeks twitched slightly, although it was to remind his subordinates, but there was no need to use this kind of thing as an analogy, right?

Besides, no one wants to get married, only Sato and Officer Takagi are more suitable.

"Don't worry, Officer Sato, there won't be any danger if we solve the case quickly." When Gao Cheng followed Sato to the apartment parking lot, he suddenly thought of the energetic Takagi.

Did Matsumoto already know about the couple's relationship?

Although he lost all the memories of the case, he still had the impression that Takagi still had a great life, and he was a winner in life many times, and now that he was there, it was impossible for Takagi to encounter danger, and it was even more impossible for Sato to be here.

With a hint of worry on his face, Sato nodded absentmindedly when he heard Gao Cheng's words, and asked, "Where are we going now?" ”

"Well, go to the mahjong parlor."

"Good...... Huh?! ”

Sato glared at Gao Cheng.

Don't say she doesn't play mahjong, now is not the time to play mahjong.

"It's just going to the mahjong parlor to investigate," Gao Cheng got into the Sato car and explained helplessly, "People of different ages, occupations and even life circles, the only thing that can be connected is hobbies, and 20 years ago, mahjong was the most likely, a more reasonable hobby?" And they all seem to have said mahjong terms. ”

"Mahjong Terminology ......"

"How many times have I carefully read the information on the serial murder case? Several of the victims were out a lot every Saturday night, and either on the phone or when they came home, they said strange things, 'Call me a crybaby, laugh endlessly,' 'I'm seeing a doctor right now!' Leave me alone! 'My parents were knocked off last night, it's terrible' or something like that......"

Gao Cheng hugged his arms and said: "It sounds like a clue, but I think of what Mr. Pingdong said who was killed this time, 'the last card', 'only the safety card'...... It's all mahjong jargon.

"Crybaby is also crying cards, mahjong is called 'calling cards', 'see a doctor' is actually 'I'm listening to it now, don't bother me', a listening is still a card can listen to the meaning of the card, at this time the BB machine has been ringing, of course will lose your temper on the phone......

"'Parents' should be the 'owner' who can take more mahjong, and 'being knocked off' should mean hitting the 'jumping full' that can be doubled, in fact, it means that the owner has lost a lot of money, and the person who heard these words was either the victim's wife who didn't play mahjong, or the victim's child, and it wasn't strange to hear it wrong, if it was investigated like this, of course, there was no result, but it was clear when you looked at it comprehensively."

The car departed, Sato listened to Gao Cheng's analysis, and the whole person became energetic, and the places that he couldn't understand before suddenly became transparent, and his eyes were shining.

"If they're really poker buddies, that is, ......"

"Yes, if you look for the mahjong parlor near their residence 20 years ago, you can find clues," Gao Cheng looked at the crowded street outside the car window, and said in a muffled voice, "I just don't know how many clues are left after so many years." ”

Sato drove the car with a solemn face, I don't know if it's a psychological effect, and I always have some bad feelings in my heart.

Now it's time for Takagi to talk to the bereaved families of the victims......

"Joto," Sato couldn't help but ask, "do you have any thoughts about the prisoner?" ”

"Well, it's not the same prisoner."

Gao Cheng looked at the flashing mahjong parlor sign on the side of the road.

Because of the relationship with the uncle who played a lot of mahjong, he is not unfamiliar with the terminology of mahjong, and from the file, it seems that the son of the third victim, who was still a child at the time, heard the last voice of the prisoner.

The child happened to hide next door in fear, and before the prisoner left humming a song, he said, "Don't blame me, who let you light the cannon ......", "It's because you said something like that, I listened to the death card, and I was targeted by the police and left such a long wound......"

Even outside the mahjong table, the prisoner likes to put mahjong terms on his lips, which shows that he is quite fond of playing mahjong.

Mr. Pingdong, who uses mahjong terminology on TV shows, is also like this, and combined with the death message left by Pingdong, a very bold possibility appears.

Pingdong is actually a prisoner, so he is so arrogant in an interview, and it is precisely because he is a real prisoner that he knows that he is being attacked by a copycat.

This speculation is entirely possible......

"Not the same prisoner?" Sato looked at Gao Cheng slightly stiffly, "What do you mean?" ”

"The English copy is copy, the word cat called cat, CopyCat, this is the name of the imitator who imitates other people's modus operandi, Ping Dong temporarily grabbed the mouse line, the real meaning may be to say the cat that catches mice...... Of course, Pingdong is dead, and I can't confirm it, so I have to go to the mahjong parlor to find further clues......"

Gao Cheng tightened his gaze.

If this is the case, it means that someone solved the case before the police, either someone can't stand the arrogance of Pingdong, or someone takes revenge for what happened in the first place.

There is also a possibility that his reasoning is wrong, Pingdong is not a prisoner, but the prisoner killed Pingdong for some reason after 15 years......
