Triple the consultant fee is a joke, but twice the price, that is, the police station will pay Kiyomi Ruri a salary, Kiyomi Ruri called the next day to say, Nakano Eri agreed without hesitation, and immediately sent a car to pick up people - the new search headquarters has just been formed, and an expert is being asked to confirm the direction of the search, and she thinks that it is best for Takeshi Nanahara to come and hear about it.

Soon, the professional group of the grassroots internship Eagle Wu Luck hummed a song and drove the car, still looking not very good-natured, waving enthusiastically to let them get in the car, pull them up and leave.

Kiyomi Ruri can legally skip school today, a little excited, and he is also an idle character, looking at the oily and powdery Eagle no luck, he asked curiously: "Eagle no police officer, I haven't seen you for this time, what are you busy with?" ”

Ying Wu Luck stroked his hair, and said with a chic smile: "That guy in Nakano is too strict, and the big case says that I am not qualified, so I have to go with a theft case first, and I was called back just now." ”

Kiyomi Ruri understood, and Eri Nakano felt that he was too annoying and kicked him into some ordinary case. Now that manpower is becoming more and more scarce, I will call him back as an errand boy, and it is estimated that when this period of time is over, eighty percent will pick another ordinary case and kick him in, so that he will get out after the nine-month internship period.

Nanahara Takeya smiled dumbly and said, "It seems that Officer Takano doesn't care much about Miss Nakano, has he already come out of the shadow of broken love?" ”

Eagle Wuluck smiled indifferently: "Of course, there are more people who like me, and I am very popular in bars and nightclubs." ”

Nanahara Takeshi nodded and smiled: "Then Miss Nakano really refused you right." ”

Ying Wuyun was stunned and said strangely: "Why did Brother Qiyuan say that?" ”

Nanahara Takeshi smiled: "If you really like Miss Nakano, how can you be rejected once and then empathize and don't fall in love." You don't really like her, and of course she should reject you...... Well, it is impossible to promise you any self-respecting and self-loving women, they are usually very cautious about their feelings, and generally only such women are worthy of serious pursuit, which is different from ordinary gold worshippers. ”

Eagle Wuluck's expression was thoughtful, and Nanahara Takeshi smiled without conscience.

Kiyomi Ruri looked at Nanahara Takeshi's smile and felt that something was wrong, so he whispered in his ear: "What are you talking about, do you want to match the two of them?" ”

Nanahara Wu turned his head and whispered in her ear: "No, it's just to find something to do for the golden glasses girl, and by the way, let's take a look at the excitement." ”

Well, Eri Nakano dared to cross him to find his mountain protection beast, stab-proof suit, housework self-propelled robot, masseuse, and air freshener, and wanted to pull him into the water through Kiyomi Ruri, which made him a little unhappy, and he was idle on the road, and he also added a little blockage to her.

"How can you do that?" Kiyoshi was unhappy, and hurriedly said to Ying Wu Lucky, "Officer Eagle Wu, don't listen to his nonsense, you better go to a bar and nightclub, the girls there are more suitable for you." ”

Eagle is not lucky to think about the words of Takeshi Nanahara, and is a little unhappy to hear this, dare I match with those superficial women who give me a brand-name bag and smile and praise me for being handsome?

He instantly made up his mind: "No! Brother Nanahara has a point, that guy in Nakano, no, Eri-chan is indeed different from ordinary women, outstanding, and has a unique charm, I really should show great sincerity to show my heart, start a serious pursuit, and slowly move her heart, it's too early to give up! ”

"Not really." Kiyomi Ruri still wanted to stop her, "Officer Takano, you're going to trouble her like this." ”

"I'm really pursuing, how can it be a problem?" Eagle is not lucky to be thinking about the next confession, what should I give at that time?

…………

Kiyomi Ruri and Takano no Luck argued and came to the Hirano Police Station, Takano no Luck put them at the door and went to park the car on his own, and by the way, he was alone to think about how to move Nakano Eri's heart.

Kiyomi Ruri got out of the car and said angrily to Nanahara Martial Arts: "Why are you so bad, why are you playing tricks on Sister Huili?" ”

Qiyuan Wu didn't care at all, and he still smiled very unconscionablely: "What are you afraid of, that guy is a rich boy, and his nature is not bad, the girl with golden glasses can't suffer a loss, and if you don't watch a good show, you won't watch it in vain." ”

Kiyomi Ruri wanted to give him two punches on his back, but there were people coming and going in the police station, and Nanahara Takeshi still had something to do, so he couldn't really beat him, so he could only pout and go to the fourth floor with him, ready to go back to Eri Nakano and report him.

Taiji Okuno and Hidakaji were waiting for them, and Eri Nakano was also afraid that Takeshi Nanahara and Ruri Kiyomi would be in danger again, so he specially arranged for two low-seniority criminal policemen to accompany them, and the four of them were grouped together. If Takeshi Nanahara has any requests, such as coming to inquire or wanting to go around somewhere, just ask Taiji Okuno and Hidakaji to come forward, she has too many things to do, and it is unlikely that she will accompany her all the way.

The four of them were now familiar with each other, and after greeting each other, Taiji Okuno led them to the back row of a large conference room, where a man in his forties was explaining a report on the podium in front of him, "So, based on my long-term analysis, I think the 'Tuesday Night Killer' should have the following characteristics.

First, he is X incompetent; Second, he is withdrawn, lacks social interaction, and hardly interacts with strangers; Third, he grew up in a single-parent family, and his father or mother was extremely strict with him since childhood, and he was subjected to long-term abuse during his childhood. Fourth, he has a history of mental illness; Fifth, he lives alone......"

This man spoke sonorously and confidently, and Kiyomi Ruri listened to it for a while and felt that it made sense.

None of the victims had ever been subjected to X, and it is highly likely that the killer did not...... What is that, and it makes sense to have a mental illness, he suddenly disappeared for five years, and it is very likely that he was imprisoned in a mental hospital and could not commit crimes, and only after being released did he relapse into the old illness.

Living alone can also be explained, he commits crimes once every three months on average, no one has reported him so far, and it is extremely unlikely that he will live with others.

She listened for a while and whispered to Taiji Okuno, "This is an expert, who is he?" ”

Taiji Okuno said in a low voice: "It's Professor Hirakawa Shi, who specializes in criminology, and today I came to make a criminal psychological portrait of the murderer." ”

Kiyomi Ruri suddenly, sure enough, he is a powerful expert, he can do a criminal psychology portrait, I heard that this is very popular in the United States, and it is an emerging detection method - there are more serial killers in the United States, what "college student killer", "Yorkshire ripper", "loner killer" and the like always have a few every year, there are more samples, and there are more researches.

Nanahara Takeya listened patiently for a while, and when he heard Hirakawa Shi start to speculate about the appearance and characteristics of the "Tuesday Night Killer", he lost much interest, turned his head and whispered to Taiji Okuno: "I want to see the criminal file records from eight years ago. ”

Taiji Okuno was surprised: "Now? Miss Nakano has also specifically told me before, I hope you will also listen to Professor Hiragawa's criminal psychology portrait, if it is okay, this may be confirmed as an important search direction in the next stage. ”

Qiyuan Wu smiled: "No, he checked him, I checked mine, now let's go and look at the criminal file records from eight years ago, to be full, the police station should have an archive, right?" ”

"Of course." Seeing that he insisted, Taiji Okuno no longer objected, and led him to carefully leave the conference room and walk to the basement of the building.

Kiyomi Ruri was a little reluctant, and wanted to continue to listen to it, after all, the "Portrait of Criminal Psychology" is a new thing, and it is still the most cutting-edge detection method at present, but of course she wants to follow Nanahara Takeshi, so she can only leave with him, but she asked puzzledly: "Why don't you listen to it well, do you think Professor Hirakawa is wrong?" ”

Nanahara Takeshi smiled: "It's true that there are some different opinions, but it's hard to say this kind of thing." ”

Kiyomi Ruri was even more puzzled, "What do you think is wrong?" ”

Nanahara Takeshi said frankly: "It's not wrong, but the psychological crime portrait is actually not very reliable, at present, it is depicted by personal intuition and experience, as far as the current technical conditions are concerned, the possibility of accurate depiction is not high, you find three people to draw portraits, I guarantee that the common delineation of the murderer will not be more than half."

For example, if I had 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 fairly good social skills, has X ability, is generally the eldest son in the family, has a stable family life in childhood but the scale of parental discipline is quite different, can control his emotions when committing crimes, is cautious and reacts quickly, can deal with emergencies, almost never fights with the victim, and has a technical job, has a normal family life, looks nothing special on the outside, and is even a little inconspicuous- Professor Hirakawa's opinion is almost completely opposite, according to him, he classifies the murderer as a person who is out of control, but I don't think so. ”

"Planning?" Kiyomi Ruri thought about it, and felt that what Nanahara Takeshi said was also a little reasonable, the previous victim did not have much resistance wounds, and it was very likely that he was attacked and had no time to resist, and the murderer was very likely to have the communicative ability to make women relax their vigilance, and the murderer did not leave any traces at the crime scene that could be traced, and he was indeed very cautious, and his self-control ability should be very strong when committing the crime.

As for whether there is X ability......

Now that I think about it, it seems that having X ability does not necessarily mean that you have to go to X victims, there seem to be a few serial killers in the United States who commit crimes just to specialize in cannibalism, and some of them are sacrificed to worship Satan, and there are certain black magic elements in them, and they don't go to X victims.

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

Nanahara Takeshi smiled: "Is this this? There are sudden big changes in normal life, such as falling in love and getting married, and after a period of happy life, my heart is very full, and I didn't come out to commit crimes again, but recently there have been big changes in my life again, like divorce and the like, and my heart has entered an empty state, which is why I came out to harm people again, what is the reason? ”

Kiyomi Ruri lowered his head and thought about it, feeling as if it could make sense, and couldn't help but hesitate: "Is that yours right or is he right?" Both of you sound reasonable! ”

Nanahara Takeshi smiled and said: "That's why I said that this kind of thing is not easy to say, everyone speculates based on intuition and experience, and no one can prove that their speculation is correct until the murderer is found." ”

Well, the portrait of criminal psychology is actually very inaccurate at first, and it is all depicted by the sample data and intuition compiled by the "mappers" themselves, but the data and intuition compiled by individuals are ...... The deviation is actually very large, and most of the time there is no reference value at all, until computers begin to be fully popularized, the Internet is online, and there is big data, and the accuracy rate is barely mentioned to an acceptable level.

Before that, the portrait of criminal psychology was actually more like a gimmick to cheat money, and the reason why it was rumored to be so miraculous was mainly survivor bias, which could cause an amazement once out of ten, and it was okay to adapt TV series and movies, and the nine times that failed...... The average person doesn't know and doesn't care.

He gave Kiyomi Ruri a brief explanation of the dilemma of the criminal psychology portrait at this stage, Kiyomi Ruri, Okuno Taiji and Hidakaji suddenly realized, dare to love the current stage of the criminal psychology portrait purely by luck, good luck can help a lot, direct blood C, bad luck is very delayed, the police can't find the murderer corresponding to the portrait for a year.

The emerging technology is really unreliable, Kiyomi Ruri was a little disappointed, but immediately asked Nanahara Takeshi: "Then what are you going to do with the criminal file eight years ago?" ”

"Of course, I'm seriously looking for clues related to the murderer." Nanahara Takeshi touched his chin and groaned, "Seven years ago, it may not be the first time the murderer committed a crime, but now the six cases are exactly the same, the modus operandi is too mature, and there is not even a process of correction and improvement, this doesn't make sense, I want to see if there are any half-finished products." ”
