"It's reasonable to say so, but why did the killer do that?" Uncle Maori touched his chin and said.

"I just looked at the body. The dead man should have been dead for more than 24 hours. That is to say, this was arranged by the murderer 24 hours ago. The sharp knife pierced through the wallet directly into the heart and died. It seems that the murderer did it again." Hattori said calmly.

"I remember you just said someone called you, didn't you?" Lin Feng asked the man.

"Yes, I'm still very strange. I called me on the roof and said there was a strange recognition planted on the roof, so I went up." the man said.

"Is it convenient for me to have a look at your mobile phone?" Lin Feng asked again.

"Of course, no problem. This is the latest mobile phone." the man took out his mobile phone and said.

Lin Feng was glad to get this man's mobile phone. This man's mobile phone is a global mobile phone, which can provide caller ID service. Otherwise, it would be really troublesome.

"Was that the number you just called?" Lin Feng said, pointing to the phone number on his mobile phone.

"Yes, that's the number. What's the problem?" the man asked.

"Don't worry, we just need to dial the phone, and then we can locate it through Telecom signals," Lin Feng said.

"In fact, I don't think it's so complicated. Since the killer asked this gentleman to go upstairs at this time, it must be nearby. We just need to call back and observe the people around us," Conan said.

"That's right." Lin Feng nodded and then dialed back.

"It's turned off!" Lin Feng shook his head at several people.

"It seems that we can only find out who this phone is. Let's go to the nearby police station first," said Hattori Pingji.

At this time, a woman suddenly drove away in panic.

"Damn it, she ran away!" koubumi did not catch up with the woman.

"I've written down her license plate, just check it," Conan said with his hands in his pockets.

So they went to the police station again. After reporting the case, the police immediately went to the scene.

"How's the phone number?" when he saw Lin Feng coming back, Hattori Pingci hurriedly asked.

"The phone is found, but the owner of the phone is ye'an and Ren, which is the dead." Lin Feng said helplessly. The murderer is really cautious.

"So? It seems that our clue is broken again." sakabe frowned. He had guessed that the case was not so easy. If it were simple, the police would have solved the case long ago.

"Is it difficult that you don't even have any clues in these cases?" Lin Feng asked. He went to check the phone before. I don't know what the results of these people's discussion are.

"Just now we were still talking about this problem. So far, we have not found a connection between these cases. Although these people have lived in Osaka since they were born, they live far away and have no intersection at all," said Hattori Pingci.

"No, if there was no intersection, the woman today would not run away in such a panic. Obviously, he knew the dead and could do some investigation in this regard." Lin Feng thought and said.

"It's easy to say. If that were the case, the police would have found the murderer," Uncle Maori said, leaning back in his chair.

"Really?" Lin Feng didn't quite understand. After all, he was not a professional detective and policeman, although he hung a name in the police department.

"Because everyone has a large circle and contacts a lot of people. Occasionally, some people overlap. However, this does not mean that there is an intersection. For example, a and B know each other, while B and C know each other, but a and C do not necessarily know each other. Therefore, it is not so easy to analyze this situation," Conan explained.

"That's not right. Now that we know that ye'an and Ren know each other well, we can analyze their intersection through big data, and then we can always find similarities in the trajectories of the more valuable dead Xikou Duodai and Changwei Yingmin. In this way, we can basically determine the common ground, and then we can find the killer in this way Human motivation, so as to lock the scope of the murderer, "Lin Feng thought and said.

"Mr. ninja, not everyone can do big data analysis," said ashihara AI leisurely.

"That's right." Lin Feng nodded approvingly. Big data analysis has not put forward the concept yet, but he will use it when he and ash yuanai are at home.

"According to Lin Feng's statement, it's also a way. I'll find someone to get all the information of these people." Hattori touched his chin and said.

"Brother Pingci, I finally found what they have in common." at this time, Sakata Youjie hurried in and said.

"Really?" said Hattori Pingci. If they find something in common, it will be very helpful for them to solve the case.

"Look!" half Yosuke stuffed a videotape into the recorder.

"Is this the Heung secretary?" said Mr Hattori.

"This should be the image taken by the Heung secretary because of the corruption storm. At that time, it was his secretary's suicide that covered up the matter, but it has been several years," said Hattori Ping with a frown.

"I remember that the Secretary of the Heung secretary is a long tail. It shouldn't be..." Uncle Maori touched his chin and said.

"Yes, it's the first victim, but what does this have to do with this case?" he said vaguely.

"No, it's the driver!" bankouke said, pointing to the pause picture.

"This driver is... Yean and Ren!" Hattori's eyes stared at the boss in an instant.

"Yes, it's yean and people. Therefore, the senior students of the police station think that there should be some clues from the township secretary. Now they have gone to the township secretary's house," said Sakata Yousuke.

"Hey, the township secretary is the last one to see the police. I'm afraid you didn't see him easily in the past." Uncle Maori said with some schadenfreude.

"Then you go to my house first. Heye knows where my house is." then the clothing department went out with Sakata Youjie.

"Hey, where are you going?" Uncle Maori shouted.

"Of course, I'm looking for the murderer. He ruined your hard trip. I'll never let him go." the clothing department said fiercely.
