i'm not a detective

Chapter 173 I want to see if there are any semi-finished products

Three times the consultant fee is a joke, but twice the price, that is, the police station will pay Kiyomi Ruri another salary. Kiyomi Ruri called the next day and said, Nakano Eri agreed without hesitation, and immediately dispatched a car. To pick up people——The new search headquarters has just been established, and experts are asking for confirmation of the search direction. She thinks that Takeshi Qiyuan should come and listen.

Soon, Ying Wulucky, the professional group who was going to practice at the grassroots level, arrived in the car, humming a song, still looking out of tune, and enthusiastically waved them to get in the car, pulled them away and left.

Seeing that Liuli can play truant legally today, she is a little excited, and she has a restless personality. Looking at the oily-faced Yingwu Lucky, she asked curiously: "Officer Yingwu, I haven't seen you for a while, what are you up to?" ?”

Yingwu luckily brushed his hair, and said with a chic smile: "That guy in Nakano is too strict. The big case said that I am not qualified, so I was asked to go with a theft case first, and I was called back just now."

Kiyoshi Ruri understood, Nakano Eri thought he was too annoying and kicked him into some ordinary case.Now that manpower is getting more and more scarce, I call him back to do errands. It is estimated that after this busy period is over, I will probably pick another ordinary case and kick him in, and let him leave after the nine-month internship.

Takeshi Qiyuan laughed dumbfoundedly and said, "It seems that Police Officer Takamu doesn't care much about Ms. Nakano anymore, have you come out of the shadow of broken love?"

Ying Wufu smiled indifferently: "Of course, there are many people who like me. I am very popular in bars and nightclubs."

Takeshi Qiyuan nodded and said with a smile: "Then Miss Nakano is right to reject you."

Ying Wuxing was stunned for a moment, and asked strangely, "Why did brother Qiyuan say that?"

Qiyuan Wu said with a smile: "If you really like Ms. Nakano, how can you be turned away after being rejected once. You don't really like her, so of course she should reject you... Well, any self-respecting and self-loving woman would not I may promise you, they are usually very cautious about their feelings, and generally only such women are worthy of serious pursuit, which is different from ordinary gold diggers."

Ying Wulucky had a thoughtful expression, and Qiyuan Wu laughed heartlessly.

Qingjian Liuli looked at Qiyuan Wu's smile, felt that something was wrong, and asked in a low voice, "What are you talking about, are you trying to match them up?"

Wu Qiyuan turned his head and whispered in her ear, "No, just find something to do for the lady with golden glasses, and let's watch the excitement by the way."

Well, Nakano Eri dared to go over him to find his mountain beast, stab-proof suit, housekeeping self-propelled robot, masseuse and air freshener, and tried to drag him into the water through Qingjian Ruri, which made him a little uncomfortable. It's also idle, and it's convenient to add some trouble to her.

"How could you do this?" Seeing that Liuli was upset, Qing quickly said to Yingwu Lucky, "Officer Yingwu, don't listen to his nonsense, you should go to a bar and nightclub, the girls there are more suitable for you."

Takano Lucky is thinking about what Nanahara Takeshi said, and hearing this is a bit unpleasant, do you dare to think that I am suitable for those superficial women who smile and praise me for being handsome when they give me a brand-name bag?

He made up his mind in an instant: "No! Brother Qiyuan is right. That Nakano guy, no, Eri-chan is indeed different from ordinary women. She stands out from the crowd and has a unique charm. I really should come up with a big one." Show your sincerity, start a serious pursuit, and slowly touch her heart, it's too early to say give up!"

"Really not." Qing Jian Liuli still wanted to stop, "Officer Yingwu, you will bring trouble to her like this."

"I pursue it sincerely, how could it be a trouble?" Ying Wufu is already thinking about the next confession, what should I give away then?
…………

Kiyomi Ruri and Takamu Lucky came to the Hirano Police Station after arguing. Takamu Lucky left them at the door and parked the car by himself. By the way, he thought about how to impress Nakano Eri's heart by himself.

Seeing Liuli getting off the car, Qing said to Qiyuan Wuqi: "Why are you so bad, why are you playing tricks on Sister Huili?"

Qiyuan Wu didn't care at all, and still smiled very heartlessly: "What are you afraid of, that guy Takamo is a rich son, and his nature is not bad. The gold-rimmed glasses girl can't suffer, and a good show is not for nothing."

Qingjian Liuli wanted to punch him with "Bangbang" on his back, but there were people coming and going in the police station, and Qiyuan Wu still had business to do, so he couldn't really hit him, so he just pouted and followed him to the fourth floor , ready to go back to Eri Nakano and report him.

Yasuji Okuno and Hidakaji were waiting for them, and Eri Nakano was also afraid that Takeshi Qihara and Ruri Kiyomi would be in danger again, so he specially arranged for two low-qualified criminal policemen to accompany them and formed them into a group of four.If Takeshi Qihara has any requirements, such as visiting the door for inquiries or wanting to go to a certain place, just ask Yasuji Okuno and Hidakaji to come forward. She has too many things to do, and it is impossible to accompany her all the way.

The four people are very familiar now, and after greeting each other, Taiji Okuno took them to the back row of a large conference room, where a man in his 40s was explaining a report on the podium in front, "So, according to my long-term Analysis, I think 'Tuesday Night Killer' should have the following characteristics.

First, he is X-incompetent; second, he has a withdrawn personality, lacks social interaction, and hardly deals with strangers; third, he grew up in a single-parent family, and his father or mother was extremely strict with him since childhood. During the period, he suffered long-term abuse; fourth, he had a history of mental illness; fifth, he lived alone..."

This man spoke sonorously and confidently. After listening to Liuli for a while, Qingjian thought it made sense.

None of the victims had ever been sexually abused, and the murderer most likely did not... what, and it makes sense to have a mental illness. He disappeared suddenly for five years, and it is very likely that he was locked up in a mental hospital and could not commit crimes. After being released, the old illness relapsed.

The state of living alone can also be explained. He commits a crime once every three months on average. No one has reported him so far, and the possibility of living with others is extremely small.

She listened for a while, then whispered to Okuno Taiji, "This is an expert, right? Who is he?"

Yasuji Okuno said in a low voice, "It's Professor Hirakawa Shi, who specializes in criminology, and came here today to make a portrait of the murderer's criminal psychology."

Qing Jian Liuli suddenly realized that she is indeed a formidable expert, who can do criminal psychology portraits. I heard that this is very popular in the United States, and it is a new detection method-there are more serial killers in the United States. What "college student killer" ", "Yorkshire Ripper", "Lonely Killer" and so on, there are always a few published every year, with more samples and more research.

Takeshi Qihara also listened patiently for a while, and when Hirakawa began to speculate on the appearance of the "Tuesday Night Killer", he lost much interest, turned his head and whispered to Okuno Taiji: "I want to see the criminal file records from eight years ago. .”

Yasuji Okuno said in surprise: "Now? Ms. Nakano specifically told me before that I hope you will also listen to Professor Hirakawa's portrait of criminal psychology. If there is no problem, this may be confirmed as an important search direction in the next stage."

Qi Yuanwu smiled and said: "No, he checked his, I checked mine, now let's look at the criminal file records from eight years ago, we need to be more complete, the police station should have files, right?"

"Of course." Seeing his insistence, Okuno Yasuji no longer objected, and led him carefully out of the meeting room and walked to the basement of the building.

Seeing that Liuli was reluctant to part with Qing, she wanted to continue to listen. After all, "Criminal Psychology Portrait" is a novelty, and it is still the most cutting-edge detection method at present, but of course she has to follow Takeshi Qiyuan, so she can only leave with him, but she doesn't understand He asked calmly: "Why don't you listen carefully, do you think Professor Pingchuan is wrong?"

Qiyuan Wu smiled and said: "It is true that there are some differences of opinion, but this kind of thing is hard to talk about."

Qing Jian Liuli was even more puzzled, "What do you think is wrong?"

Takeshi Qihara said frankly: "It's not wrong, but the psychological crime portrait is not very reliable. Currently, it is drawn based on personal intuition and experience. Given the current technical conditions, the possibility of accurate depiction is not high. If you draw portraits of all three people, I guarantee that the depicted murderers will have no more than half in common.

For example, if I were to portray this serial killer, I would classify him as a mastermind.

This type of serial killer usually has high intelligence, is well-educated, has quite good social skills, and has X-ability. He is usually the eldest son in the family. He has a stable family life in childhood, but the parental discipline standards are quite different. He can control the crime My own emotions, cautious and quick response, able to deal with emergencies, almost never fight with the victim, and have a technical job, have a normal family life, nothing special in appearance, even a little inconspicuous - I Professor Hirakawa's view is almost completely opposite. According to him, he classified the murderer as an out-of-control type, but I don't think so. "

"Planning type?" Qingjian Liuli thought for a while, and felt that what Takeshi Qiyuan said made sense. The previous victim did not have many resistance injuries. It is very likely that he was attacked and there was no time to resist. The murderer most likely had the ability to make women relax. Vigilant communication skills, and the murderer did not leave any traces at the crime scene to be traced. He was indeed very cautious, and he should have strong self-control ability when committing crimes.

As for whether he has X ability...

Thinking about it now, it seems that having the ability to X does not necessarily mean that you must rape the victim. There seem to be a few serial killers in the United States who commit crimes just to eat people, and some of them are sacrificed to worship Satan. Elements of black magic are in it, and it doesn't go to rape the victim.

She thought for a while, and then asked again: "But how do you explain that he disappeared for five years? Your speculation sounds like the murderer is a normal person."

Qiyuan Wu smiled and said: "Is this? There are sudden big changes in normal life, such as falling in love and getting married, and after a period of happy life, the heart is very fulfilled and has not come out to commit crimes again, but recently there have been big changes in life again, like divorce And so on, the heart has entered a state of emptiness again, and then it comes out to harm others, what is the reason?"

Qing Jian Liuli lowered her head and thought for a while, feeling that it also made sense, she couldn't help hesitating and said, "Is that you right or he right? Both of you sound reasonable!"

Qiyuan Wu smiled and said: "That's why I said that this kind of thing is hard to say. Everyone guesses based on intuition and experience. Before the murderer is found out, no one can prove that his speculation is correct."

Well, the criminal psychology portrait was actually very inaccurate at the beginning, and it was all based on the sample data and intuition compiled by the "drawer". , until computers began to be widely used, the Internet went online, and with big data, the accuracy rate barely reached an acceptable level.

Prior to this, the criminal psychology portrait was actually more like a gimmick to cheat funds. The reason why it was spread so miraculously was mainly due to the deviation of survivors. Faced with it once in ten times, it can cause amazement. It is not a problem to adapt TV series and movies. And those nine times of failure... Most people don't know, and don't care.

He gave Qingjian Ruri a brief explanation of the predicament of criminal psychology portraits at the current stage. Qingjian Ruri, Okuno Taiji and Hidakaji suddenly realized that the current stage of criminal psychology portraits is purely based on luck. Good luck can help a lot, and the direct blood C, Bad luck wasted time, the police searched for a year and couldn't find the murderer corresponding to the portrait.

The emerging technology was really unreliable, Qing saw Liuli was a little disappointed, but immediately asked Qi Yuanwu: "Then why do you want to read the criminal files from eight years ago?"

"Of course I'm seriously looking for clues related to the murderer." Takeshi Qiyuan touched his chin and pondered, "Seven years ago, it may not be the first time the murderer committed a crime. The six cases now are exactly the same, and the modus operandi is too mature. There is no process of correction and improvement, which does not make sense, I want to see if there is any semi-finished product."
