"The time of the deceased's death should be about a day! There was a stab wound in the chest, and the knife pierced through the wallet, stabbing the deceased in the chest! But this was not the cause of his death, it was this strangulation mark on his neck that really killed him! It can be preliminarily judged that the deceased was strangled to death first and then disguised like this with a knife and wallet! This is exactly the same method as the previous cases! Could this be another victim in a serial murder? With the help of Yuichi on the side, Yusuke Sakata quickly conducted a preliminary inquest on the corpse that fell from the sky, and the results of the inquest were also recognized by Yuichi here.

Just when Yuichi heard Sakata's inference and wanted to ask about the details of this serial murder case, the other side went upstairs to find the mysterious person who had just looked down, and Conan, who was with him, also brought a somewhat bald old man over.

"This is the mysterious man who just stood upstairs, but unfortunately he is not the real murderer, he is the owner of the tea shop on the second floor! Someone just called him and said there was a strange man on the roof, tell him to go upstairs and have a look! Then he went to the roof and opened the door and all this happened, and he didn't know what was going on, so he climbed on the roof and looked down! ”

"Did it fall off as soon as you opened the door? This modus operandi is inexplicably familiar! Yukai, who heard Heiji's explanation, touched his chin after glancing at the body tied by rope in front of him, and muttered thoughtfully.

And Pingji, who went on to say that he was surveying the situation upstairs, immediately confirmed his suspicion and made him think about why he was so familiar.

"There are traces of being strangled by a rope on the doorknob on the top floor, and there is a plastic sheet floating not far away, according to the specific investigation of the scene, it can be found that the criminal modus operandi of the suicide incident of Butterfly Wild Spring that you solved last time is the same, the murderer also tied up the body and hung it with a rope outside the top guardrail of the upper floor, and then hung the rope hanging him on the top doorknob, just now I don't know for what reason I called the owner of the tea shop on the second floor, so when we came out, the body appeared in front of us."

"Oh? So look at it! Is the killer targeting the Osaka police or you? When the body was first examined, Officer Sakata and I had already determined that it had been about a day since the deceased died, and it was strange that this body fell on the police car so accidentally! Especially what Serial Murder Officer Sakata said just now, it seems that this is not the first victim! And they should still die the same! Am I right to make Officer Sakata make such a judgment? After listening to Heiji's reasoning, Yuichi, who looked down and thought, immediately realized that this case had nothing to do with himself and others, but a continuation of a serial murder case that the Osaka police were solving.

But before Heiji could express his admiration for Yuichi's reasoning, a beautiful woman with a long black straight melon seed face in the crowd of onlookers suddenly screamed and turned around and left the crowd, driving her own car and disappearing into the scene of the crime.

"Do you think she's going to be a murderer?"

"Probably not! If the murderer stayed at the scene of the crime after the murder to observe, it would not be her like this, but she must be an insider! And it could be the next victim! Well, don't be a pity! I just wrote down the license plate number of her car, you can just let the police check it later, and now the most important thing is to tell me about this so-called serial murder case, is that okay? Hattori! ”

"Of course! Have a good fight with you, a famous detective in Kanto, I can't ask for it! ”

Yuichi, who has never been interested in the thankless task of crossing the border and meddling in cases handled by other county police, is essentially resistant to this kind of serial murder case, but with the two bastards Conan and Heiji, how can he go to Osaka Castle if such a thing happens, so he waited until the Osaka police who came to the police to hurriedly investigate the scene and make some handovers with Yusuke Sakata, and the group in the police car came to the Tojiri Branch of the Osaka Police Station inexplicably.

"Including this man, three dead people have been killed by this murderous method since the beginning of this week."

"Is this the kind of knife that goes through the purse and into the chest, and is it all this form of murder after being strangled?"

"That's right! The first person to be killed was Hidetoshi Nagao, a store manager at a convenience store. The second person to be killed was an izakaya proprietress named Tayo Nishiguchi. And then there's the deceased who fell just now, his name is Noyasu and people, and he is a taxi driver! None of them looked like people would be killed for money, not to mention that none of the three had anything to do so far! Therefore, the inference that the murder was triggered because of the financial dispute was also denied, and the whole case came to an impasse! ”

"Is that so? So what do you mean by irrelevance? In the face of Heiji's whispered explanation, Conan, who has obviously been attracted to this kind of murder, is like an addict! I can't wait to urge Pingji to tell the clues behind it.

And Heiji, who was obviously the same kind of person as him, did not disappoint him, and after observing left and right, he saw that Yuichi and the others had not paid attention to this side, so he whispered an explanation to Conan's ear.

"The so-called irrelevancy is that although the birthplace of these three deceased, the school they attended, and the place of work were all in Osaka, but in terms of the smaller location, they were completely different, and their lives seemed to have no intersection, but the strange thing is that they were all killed by the murderer!"

"Could it be a random killing incident by a perverted murderer out of self-satisfaction or revenge for society?"

"Nope! I don't think so! If it is a random killing, how can we explain the case that happened today? Ye An and people were killed yesterday, but the murderer designed a mechanism to let him fall from the upper floor today, this behavior is obviously to warn someone, not our Osaka police, it should be the woman who screamed and fled from the scene today, that is to say, the murderer killed people for a purpose, he was not a random killing, it's just that we haven't found the internal connection between these people! ”

"I see?"

Just when things were at an impasse and Conan and Heiji, the two major detectives in Kanto and Kansai, were making no progress, Yusuke Sakata, who had just been sent out to find the name of the owner of the family with the license plate number written by Conan, ran in with excitement on his face.

"Flat! A major discovery! Found the common ground of the victims! ”

"Really?"

"Hmmm! Let's take a look at this tape first! ”

"Huh? Video of a live interview six years ago about the alleged corruption of Sotaro Goji, a member of the Prefectural Assembly? Sakata, why are you giving me this? ”

"You can see it! I just borrowed it from the TV station! ”

So in front of the TV in the police station, a man named Sotaro Goji gradually appeared on the suspicion list of the people watching the videotape.
