The famous criminal in the world of Conan

When Bai Masong talks about solving cases, he changes his usual behavior. He is now really like a top student who is teaching problem-solving techniques to poor students.

Sato Miwako also listened very seriously, took out the police notebook and pen she carried with her, and began to take notes.

Seeing Sato Miwako's look, Bai Masong stopped explaining and waited for her to finish taking notes.

"Rustle, rustle" Sato Miwako was writing when she found that there seemed to be no sound. She looked up and found that Bai Masong was also looking at her.

She blushed and said embarrassedly: "I, I'm afraid I can't remember it."

"Have you finished memorizing it now?" Bai Masong asked.

"I've finished."

"Then let's talk about the proof question," Bai Masong continued. "The proof question means that although the murderer is unknown, there is only one suspect at the scene, and he is most likely the murderer, such as the disappearance of the body incident encountered a few days ago. What we have to do is to solve the puzzle he set."

"For this type of question, it may be more troublesome if we want to solve the puzzle, but we can just not answer the question."

"Don't you want to take up the question?" asked Miwako Sato.

"That's right. For the proof question, we basically already know the murderer. At this point, in our eyes, any of his actions are problematic. We just need to restrict his behavior, bypass his puzzles, or even prevent him from setting questions, and we can solve the case directly."

"So!" Sato Miwako understood. "So, Inspector Hakuba, you followed Mr. Tanaka upstairs a few days ago to restrict his behavior and prevent him from setting questions!"

"Yeah," Bai Masong nodded. The boy is teachable.

"In addition," Bai Masong said, "we can use a method to deal with all problems. This method is very effective, and that is body search!"

"search?"

"Locard's exchange law states that once a criminal commits a crime, there will be a material exchange between the criminal and the crime scene. Therefore, after a suspect sets a question, there will be more or less traces of the crime scene on his body, and a body search can effectively detect them."

"Yes, yes, body search. I remember that." Sato Miwako nodded vigorously, and then asked, "Inspector Hakuba, is there anything else?"

"There are also some techniques to quickly identify suspects." Bai Masong asked the boss for a bottle of water, took a sip, and continued.

"First, to identify the suspects, we must first rule out the possibility of roving crimes or random crimes."

"Eh? Why?"

Because there are no roving crimes or random crimes in Conan, Bai Masong thought so. Although he thought so, it was impossible to say so.

"Because these two possibilities will consume a lot of manpower and material resources, instead of doing so, we can first check the suspects present. Moreover, after the suspects have asked a question once, they will generally be very confident and will not flee the scene." Bai Masong said seriously.

"Oh, that makes sense."

"Also, among the suspects at the scene, the one with the least possibility of committing the crime and the most convincing alibi is the most suspicious," said Bai Masong.

"Huh? Why is this?" Sato Miwako was even more confused. Shouldn't the person in this situation be the least suspicious?

"This one should be considered in conjunction with the previous one, because the suspect was very confident and stayed at the scene. Why was he so confident? Because he was least likely to have committed the crime and his alibi was the most complete!" Bai Masong explained, "This is taking advantage of the suspect's criminal psychology, which is a type of criminal psychology."

Well, it’s actually science.

"That's amazing! Inspector Hakuba, did you study this when you were studying abroad?" Sato Miwako said with admiration.

"Yeah." Bai Masong said calmly without changing his expression.

"Another thing is that if one of the suspects keeps revealing information himself, or drags others to reveal information, then his suspicion will increase."

This time, Sato Miwako did not continue to ask why, thinking about waiting for Bai Basong to finish speaking.

"Because the suspect did this to muddy the waters and make everyone suspicious. Plus, if he has an alibi, he can be cleared of suspicion." Bai Masong continued, "This is also the application of criminal psychology."

This is also the application of science!

"Well, that's about it. If you encounter a case in the future, you can also practice it. If you find anything new, I will also add it. Any other questions?"

"No, no more. Today, I am really grateful to Chief White Horse!"

"fine."

After getting Sato Miwako's answer, Hakuba Matsu said it was time to end.

After Sato Miwako rushed to pay the bill, the two left the ramen restaurant and went to the parking lot. During this time, Sato Miwako repeatedly expressed her gratitude, and then the two went home.

.............................

Time quickly came to the next day.

Bai Masong felt something was wrong today. At work, many people looked at him with "emotions", the kind of envy, jealousy and hatred.

Bai Masong came to the seat, sat down, and took out a case report.

Officer Narasawaji, who was working at the desk next to him, saw Bai Masong coming, stood up and walked to Bai Masong's desk.

"Hakuba-san." Narasawaji said seriously, "We all know about your relationship with Detective Sato. Since Miwako chose you, please treat her well and take on your responsibilities as a man!"

Officer Narasawa placed his hand heavily on Bai Basong's shoulder and spoke earnestly.

"please!"

Narasawa Osamu is 48 years old this year and holds the rank of inspector general. He is a senior criminal policeman who has been working on the front line for many years. He and Sato Miwako were previously in Inspector Tomonari's team.

He has an old friendship with Sato Masayoshi. He is an elder who has watched Sato Miwako grow up and has always treated her as his daughter.

At the same time, he is also a member of Sato Miwako's defense line.

Bai Masong also knew this, and after hearing this, he realized that Officer Nara Zeji had misunderstood.

"You misunderstood. Detective Sato and I don't have that kind of relationship." Bai Masong said lightly.

When Nara Zezhi heard this, he frowned and was about to get angry.

Sato Miwako also heard what the two said, and quickly stood up and explained with a blushing face.

"Officer Narasawa, I just asked Inspector Hakuba for some tips on solving cases yesterday. Nothing happened between us."

Narasawaji looked at the two of them suspiciously and wanted to say something, but at this time, Inspector Megure walked in and spoke loudly.

"We just received a report that a murder occurred at xxxx. Hakuba, Sato, Takagi, follow me immediately."
