On the other hand, Takagi didn't know that Sato was taken away by Gao Cheng to protect him, and he concentrated on asking the relatives of the victims one after another, along with Conan and Ayumi who followed the car, and only Xiao Ai was absent because he had to rush home to cook for Gao Cheng.

This will make Takagi feel so tired, there is no little mourning who likes a poisonous tongue, and it is difficult for a few bear children to deal with, but fortunately, except for Conan, the others are willing to stay in the car.

"The last person I want to meet is Mr. Nagaki, the son of lawyer Nabii who was killed five years after the murder 20 years ago."

Takagi had seen that there were no clues from the two families, and his initial motivation had been worn out a lot.

Originally, Sato said that if he solved the case, he would go to the hot spring with him, the kind of two people together......

"Mr. Yonggui, who was only 10 years old at the time of the incident, was taking a nap in his room and woke up after hearing his father's screams, but from the time the mortal left to the time his mother came home from shopping, he hid in his room in fear and did not dare to go out......"

"Maybe it would be better to hear what his mother has to say." Conan suggested.

"No, Mrs. Naboi was hit after finding out that her husband died tragically, and now he is still in the hospital, and Mr. Yonggui seems to be living at home alone."

Nabii Yonggui, 25 years old, the son of the victim Nabii lawyer, with thick eyebrows hanging upwards and a beard on his chin, looks quite difficult to mess with, and he did lose his temper when he saw Takagi, and finally drove Takagi away without saying anything, and he didn't even get in the door.

"Uh," Takagi drove away slightly embarrassed, "He didn't seem to be such a person before, the police officer said that whether it was the situation at the time of the incident or the strange things that Dad had said, as long as he thought of it, he would take the initiative to tell the police, and ran to the police station many times......"

"Strange words?" Conan felt that he was getting closer and closer to the truth.

"Yes, most of the Sundays slept until noon, and when I woke up, I always muttered, 'My parents were knocked off last night, it's terrible'...... I think so......"

"Really?"

The corners of Conan's mouth went up, and he laughed brightly.

"I finally got it...... The connection between the four victims is mahjong!! ”

……

At the Okokho-cho mahjong parlor, Takasei and Officer Sato walked out the door and returned to the car.

Very lucky, the mahjong parlor of that year is still there, and the store manager recognized the 4 people who played mahjong together that year.

Doctors, associate professors of the Faculty of Science and Engineering, rookie lawyers and college students studying criminal psychology, 4 people of different ages are quite compatible, every Saturday night at 10 o'clock, they will gather in the mahjong hall to play mahjong, and they always like to reason about the cases that happen in reality, and the reasoning is quite accurate, so the boss is impressed.

But the 4 people only played mahjong together for 2 years.,Since the topic talked about what kind of complete crime or something.,Only Pingdong, who was a college student at the time, came over after a while.,Sitting alone at a table where no one slowly wipes mahjong tiles.。

The boss rarely watched the news, and he didn't think that all four people were killed, and when questioned by Officer Sato, he provided a clue about a suspect.

Back then, there was a guest who often picked on the reasoning of 4 people, because he said that there were no more than 4 people who had a grudge, and when Pingdong was alone, Pingdong had a fight, and even yelled to kill all 4 people.

The store manager didn't remember the other party's name, but the fight was very serious, and the tables and chairs were thrown around, so both of them were taken away by the police from the nearby police station.

"I found it," Sato said when he found the records of that year at the police station, "Mr. Heiton made a noise that it was Onibo Duro who was taken away by the police, and he had no fixed residence or occupation...... It's that robber ghost Bao Poison Lang, who just finished his 15-year sentence and was only released from prison a few days ago! ”

Sato looked at Gao Cheng with excitement in his eyes.

So it makes sense, the reason why there have been no serial killings in 15 years is because the prisoner has been in prison for 15 years because of the robbery and cannot do it.

And according to the manager of the mahjong parlor, there happened to be a strange person calling the mahjong parlor in the day before he started, as if to confirm whether the remaining person was a criminal psychologist before he started killing.

has been in prison for 15 years, and has been very consistent with the ghost protector who has been isolated from the outside world......

Gao Cheng looked at the records in his hand and frowned.

"It seems that the prisoner is indeed this person called Onibao, but ...... He was not the prisoner. ”

"Why? Mr. Pingdong's death information is not without the possibility of being falsified by the prisoner, if ......"

"That's even more unlikely, the prisoner is a very cautious person, he won't leave such a big hole, kill people just after he gets out of prison, and there is no reason for such a person to talk about Let it be, let alone shed tears......"

Gao Cheng's mind left the police station at a rapid pace, and he didn't even stop shouting from Sato behind.

"Joto, what's wrong?" Sato hurriedly followed Gao Cheng into the car.

"It's not the ghost who called the mahjong parlor," Gao Cheng said seriously, "The reason why I asked the fourth person if he was a criminal psychologist was because I happened to see Mr. Pingdong's program, if it was a ghost insurance, seeing the current Pingdong plus his identity as a criminal psychologist, he could immediately remember, and both of them were taken away by the police, so they wouldn't even know each other's names......

"The reason why there was this call is because the prisoner had never seen Mr. Pingdong before, and he didn't know that the fourth person was a criminal psychologist, to be precise, the prisoner only thought of the fourth person who played mahjong through Mr. Pingdong's voice!"

"Voice, voice?!" Sato's pupils dilated slightly.

"Yes, Mr. Hiradong, who has been appearing on TV shows these days, likes to speak with a unique voice of mahjong terminology......"

Gao Cheng opened the detective badge and contacted Conan on the other side, who had just investigated the mahjong parlor.

"The reason why it will be 15 years ago is not because the murderer went to prison, but after 15 years, I only knew the mahjong term, and 15 years later, I recognized the original prisoner through the voice, and the letters behind Mr. Pingdong are not N not because the murderer didn't want to engrave, but because it couldn't be engraved, because it was originally to hide the long scar on Mr. Pingdong's back......

"That's why I carved out the Z in a compromise."

"What's going on?" Conan's face on the opposite side changed slightly, "Could it be that this case ......?"

"This time is revenge for the events of 15 years, and the person who killed Mr. Hirato should be Nabii Yonggui who hid in the room and only heard the voice of the enemy who killed his father."

"Is it the kid from the beginning?!" Sato exclaimed in surprise, "But what about the ghost protector? ...... can't be entirely certain right now."

"Of course, the ghost protector can investigate, but now as long as you go to the pot well house again, there should be a result."

Gao Cheng has summarized all the clues in his heart, there is no error in reasoning, the only thing missing is evidence.

But if there are no accidents, this case should be over here, and he is still a little confident in his reasoning......

"We've already been to Mr. Yonggui's house," Takagi said with a bitter face, "but Mr. Yonggui won't say anything, and he is completely two people when he was a child." ”

It's over, Sato's side solved the case first, and the hot spring is gone......
