Detective Training Manual

　　 is indeed a provocation.

　　The murderer was supposed to avoid getting blood on his body, so he wore a raincoat and killed someone...Then he dragged the raincoat and threw it into the trash can at the back door of the video studio.

　　 He didn't want to hide, he didn't even bother to throw it a little farther away, and just throw it away at the scene of the crime.

Sister Yazi was silent, and walked to the back of the video room with the police officer. There was a small path leading to it. It was very narrow and messy. Several trash bins were piled on the wall, emitting an unpleasant smell. It has been a long time since no one has cleaned it up, but because almost no one has entered the alley, the trash cans have not been filled up yet.

　　Beside the trash can closest to the outside, several members of the forensics team have begun to take photos of the exhibits.

　　 Seeing Sister Masahiro coming over, everyone acquainted with each other and stepped aside.

　　 Among the crowd, there is a **** raincoat. It is very long. There are some sporadic blood stains on it. I think it was left when the throat of the dead was cut.

　　 And right next to the raincoat is a knife.

　　 Very common utility knife, you can buy it in all shops.

　　 Sister Masako looked at this scene in front of her...

　　 "Zhou Yan?!"

"what's happenin?"

　　 "Tell me what you saw?" Masako asked.

　　 Zhou Yan understood that this was another test for himself, so he looked at the raincoat and utility knife very seriously.

　　"The murderer man, the raincoat was specially bought in a large size, and his height was over 180 cm.

　　 There are no signs of fighting in the office of the video room, so the murderer should be familiar with the dead, or the murderer Kong Wuli.

　　 After all, a video studio owner on the ground floor saw a person walking in wearing a raincoat. He should be able to understand what is going to happen on the spot, so the murderer must subdue the dead within a few seconds, otherwise the scene will not be so tidy.

　　 Another thing is that the murderer is very familiar with the surrounding environment. He has already planned the retreat route, knowing that no one is passing through the alley, and there is no camera. "

　　 Sister Masa nodded: "Well, from the perspective of reasoning, it's almost enough to do this."

　　 Zhou Yan breathed a sigh of relief. Although the reasoning was not perfect, no points were deducted.

　　 But then...

"Male, over 35 years old, company employee, but the position belongs to the leadership class, has a certain financial strength, and is usually shown as a generous old man, but his inner personality is strict, arrogant and narcissistic, with slight cleanliness, pay attention to maintenance, and also Lazy, or superficial personality that pays special attention to one's own image.

So what we are looking for now is a kind, suit and leather company leader who is over 35 years old but takes care of his beard and hair. Moreover, this company cannot be a small company on the street. The kind with face. "

　　 "Hiss..." Zhou Yan couldn't help but be surprised: "What...how did these come out?"

　　Yes, from start to finish, the murderer has never been seen, only the murder weapon and the raincoat are left. From the current evidence collection, these inferences by Sister Yazi are unfounded?

Sister Yazi smiled: "This is the difference between reasoning and profiling... Reasoning must be based on feasible evidence, while profiling... is based on data. of."

　　 "Data?"

"Yes, just give a very typical example. If in the past 50 years, 80% of all prisoners who like to abuse women have experienced domestic violence in their childhood, then in the profile, you can directly target the target Set as childhood misfortune!

　　 Although it is very sloppy to do so, the profile is like this, it is based on the case of the past dozens or even hundreds of years, and made a reasoning without evidence. "

　　 Zhou Yan was stunned. Although he had understood the profile a little bit before, but listening to Sister Yazi's words, he seemed to feel that what he knew before was not the case at all.

　　 "But... how did the inferences you made just now come out, such as... laziness, cleanliness, company leadership, these are definitely not made up by you?"

　　 Sister Yazi gave Zhou Yan a white look: "I'm not like you, talking nonsense. My profile writing success rate can reach more than 60%."

　　 "It's only 60%."

"Oh, this is a profile. A profile with a success rate of more than 60%. I even dare to say that if the prisoners in this city vote collectively to select a detective who should be killed the most, it will be me in all likelihood. , Those Sherlock-level players have to go back."

　　 Indeed, a person who can lock the murderer first without evidence is too scary to think about.

　　 "Okay, answer your question... The murderer's laziness is the most important aspect of his character, because he wears a utility knife."

　　 "Huh?" Zhou Yan really couldn't keep up with Yazi's thinking now.

"I don't know if you have this habit, that is...When you go out for a long journey, you only like to bring one piece of luggage. Whether it is a luggage bag or a suitcase, the size does not matter, anyway... ...You just want to bring one, stuff everything in.

　　 And if you carry a bunch of big and small bags, your heart will be particularly annoying.

　　This...is the laziness of the character. "

　　 "This...?" Zhou Yan frowned. He seemed to understand a little bit, but he was a little uncertain.

Sister Yazi continued: "The murderer’s character accounted for a huge proportion. He needed a raincoat. He didn’t want to pack it in plastic bags because he felt that it would be troublesome to throw away the plastic bags. To hold a knife...It's like taking two packages while traveling, which makes the murderer very uncomfortable."

　　 "Does this make him feel uncomfortable?"

　　 "Yes, it is difficult for a person without this kind of personality to understand this feeling. In short, he only wants to hold a raincoat, so... when choosing a knife, he chose a utility knife.

You know, when killing people, the utility knife is the worst choice, because it is too brittle~www.wuxiaspot.com~ It will break easily. When it is stabbed on the clothes, it is very likely that the clothes will not be broken. The only thing is The only way to kill may be to cut the throat.

　　 So, do you think why the murderer gave up the fruit knife and took a utility knife? "

　　 Zhou Yan tried his best to guess the murderer's thinking from the perspective of profiling.

　　 "Because...because..." Suddenly, Zhou Yan seemed to have caught a little bit: "Because the blade of the utility knife can be stowed away, and it is small in size, so it can be carried in the pocket?"

　　 "That's right! It's because the utility knife can be kicked in the pocket." Sister Yazi smiled. Seeing Zhou Yan came to the correct conclusion, she seemed to feel less angry.

　　 "But... just because you can hold it in your pocket? Isn't this conclusion too sloppy?"

　　 "Yes, it's sloppy, but the profiling is not just to determine a person's character from one point, but to guess a person from all aspects, and then come up with all the intersections of speculation...

　　Let’s do this, now I have a question for you. "

　　 said, Sister Masa pointed at the trash cans in front of her.

"There are a total of three trash cans here, and there are two close to the back door of the video room. After coming out of the house, just throw the raincoat into the bucket. But why, the murderer has to throw the raincoat and the murder weapon to the nearest one. At the exit of the alley, where is the third trash can most easily seen by pedestrians?"
