I'm Not a Detective

Triple the consulting fee is a joke, but twice the price means that the police station will pay Qingmi Ruri another salary. Qingmi Ruri called the next day and Nakano Eri agreed without hesitation and immediately sent a car to the front Go to pick someone up - the new search headquarters has just been established and is asking experts to confirm the search direction. She thinks it would be best for Takeshi Nanahara to come and listen.

Soon, Ying Wulu, who was working as an intern at the grassroots level, drove up in a car and hummed a song. He still looked like an off-kilter slut. He waved enthusiastically to them to get in the car, pulled them on and left.

Qing Jian Liuli could legally play truant today. She was a little excited and had a restless personality. She looked at the greasy-faced Ying Mo and asked curiously: "Officer Ying Wu, I haven't seen you in this time. What are you doing?" ?”

Ying Wu luckily flipped his hair and said with a smart smile: "That guy from Nakano is too strict. He said I'm not qualified for the big case. He asked me to go to a theft case first. I was called back just now."

Qing Jian Ruri understood, but Nakano Eri thought he was too annoying and kicked him into an ordinary case. Now that manpower is becoming increasingly scarce, they have called him back to work as an errand boy. It is estimated that when the busy period is over, they will probably pick another ordinary case to kick him in and let him get out after completing the nine-month internship period.

Takeya Nanabahara laughed dumbly and said: "It seems that Officer Takamu doesn't care much about Miss Nakano anymore. Has he gotten over the shadow of broken love?"

Yingwu Luck smiled nonchalantly and said: "Of course, there are many people who like me. I am very popular in bars and nightclubs."

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

Ying Wuxu was stunned for a moment and asked strangely: "Why did Brother Qiyuan say that?"

Takeshi Nanahara smiled and said: "If you really like Miss Nakano, how could you fall in love with someone else 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 Maybe I promise you, they are usually very cautious about relationships, and generally only such women are worthy of serious pursuit, unlike ordinary gold-worshiping women."

Taka no Lucky looked thoughtful, and Takeshi Nanahara smiled heartlessly.

Qingjian Liuli looked at Qingqi Yuanwu's smile and felt something was wrong. Fu Er asked in a low voice: "Why are you talking about this? Do you want to bring them together?"

Takeshi Nanahara turned his head and laughed softly in her ear: "No, I just want to find something for the lady with gold glasses to do, and we can also watch the excitement."

Well, Nakano Eri dared to cross him to find his mountain guardian beast, anti-stab suit, housekeeping robot, masseur and air freshener, and also wanted to drag him into the water through Qingmi Ruri, which made him a little unhappy. It was also idle, and he also added some trouble to her.

"How could you do this?" Qingjian Liuli was unhappy and quickly said to Yingwu Lucky, "Officer Yingwu, don't listen to his nonsense. You'd better go to a bar or nightclub. The girls there are more suitable for you."

Takashi was thinking about Takeshi Nanabaru's words. He felt a little unhappy when he heard these words. Do you dare to think that I am a good match for those superficial women who just smile and compliment me on my handsomeness when they give me a brand-name bag?

He made up his mind in an instant: "No! What Brother Nanabahara said makes sense. That guy Nakano, no, Eri-chan is indeed different from ordinary women. She stands out from the crowd and has a unique charm. I should really come up with something big." Show your sincerity, start a serious pursuit, slowly move her heart, and it’s too early to give up!”

"It's really not possible." Qingjian Liuli still wanted to stop her, "Officer Takamu, you will cause trouble to her."

"I'm sincerely pursuing you, how can it be troublesome?" Yingwu Luck is already thinking about his next confession. What should he give then?

…………

Qingmi Ruri and Takano Lucky arrived at the Hirano Police Station after arguing. Takano Lucky placed them at the door and parked the car. By the way, he was alone to think about how to impress Nakano Eri.

When Qing saw Liuli getting out of the car, she rushed to Nanabahara Takeki and said, "Why are you so bad? Why are you teasing Sister Eri?"

Takeshi Nanahara didn't care at all, he still smiled very heartlessly: "What are you afraid of? That guy Takamu is a rich young man, and his nature is not bad. The girl with gold-rimmed glasses can't suffer. If you don't watch the good show, you won't see it in vain."

Qingjian Ruri wanted to give him a "Bang Bang" punch on his back, but people were coming and going in the police station. Takeshi Nanahara had other things to do, so she couldn't really hit him, so she could only follow him to the fourth floor with a pouted mouth. , preparing to go back to Eri Nakano to report him.

Taiji Okuno and Hidakaji were waiting for them. Eri Nakano was also afraid that Takeshi Nanahara and Ruri Qingmi would be in danger again, so he specially arranged for two low-qualified criminal police officers to accompany them, forming a group of four of them. If Takeshi Nanahara has any request, such as visiting for inquiries or wanting to go somewhere, just ask Okuno Taiji and Hidakaji to come forward. She has too many things to do and is unlikely to accompany her throughout the whole process.

The four people were now very familiar with each other and greeted each other. Taiji Okuno took them to the back row of a large conference room. There was a man in his forties explaining a report on the front podium, "So, according to my From a long-term analysis, I think 'Tuesday Night Killer' should have the following characteristics.

First, he is X incompetent; second, he is withdrawn, lacks social interaction, and rarely interacts with strangers; third, he grew up in a single-parent family, and his father or mother were extremely strict with him in his childhood. He suffered long-term abuse during his period; fourth, he has a history of mental illness; fifth, he lives alone..."

This man spoke forcefully and confidently. Qingjian Liuli listened for a while and felt that it made sense.

None of the victims had ever been sexually assaulted. It was very likely that the murderer had not...that thing, and it would also make sense to have mental illness. He disappeared suddenly for five years, and it was most likely that he was imprisoned in a mental hospital and was unable to commit crimes. After being released, he relapsed.

Living alone can also be explained. He commits a crime once every three months on average. No one has reported him so far. It is extremely unlikely that he lives with others.

She listened for a while and asked in a low voice to Taiji Okuno: "Is this an expert? Who is he?"

Taiji Okuno whispered: "This is Professor Hirakawa Shi, who majors in criminology. Today he came specifically to do a psychological portrait of the murderer."

Qing Jian Liuli suddenly realized that he was indeed a powerful expert who could do psychological profiling of criminals. I heard that this is very popular in the United States and is an emerging detection method - there are more serial killers in the United States, what about "college student killers" ", "Yorkshire Ripper", "Loner Killer", etc. There are always a few released every year, with more samples and more research.

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

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

Takeshi Nanahara smiled and said, "No, he checked his, and I checked mine. Now let's go look at the criminal files and records from eight years ago. They need to be more complete. The police station should have archives, right?"

"Of course." Taiji Okuno saw that he insisted and no longer objected, leading him carefully out of the conference room and towards the basement of the building.

Qing Jian Liuli was a little reluctant to leave and wanted to continue listening. After all, "criminal psychology profiling" was a new thing and the most cutting-edge detection method at present. But of course she had to follow Takeshi Shichihara and could only leave with him, but she didn't understand. He asked: "Why don't you listen carefully? Do you think Professor Hirakawa is right?"

Takeshi Nanahara smiled and said: "I do have some differences of opinion, but it's hard to talk about this kind of thing."

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

Takeshi Nanabaru said frankly: "It's not wrong, but psychological criminal portraits are actually not very reliable. Currently, they are all 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 three people, I guarantee that the murderers depicted will not have more than half in common.

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

This type of serial killer usually has high intelligence, is well-educated, has pretty good social skills, and has X ability. He is usually the eldest son in the family. His family life was stable during his childhood, but his parents' discipline standards varied greatly. He can control them when committing crimes. My emotions are cautious and quick to react, I can deal with emergencies, I rarely fight with victims, and I have a technical job and a normal family life, and my appearance is nothing special, even a little inconspicuous - I Professor Hirakawa's view is almost exactly the opposite. According to him, he classified the murderer as someone who lost control of his heart, but I don't think it is the case. "

"Planning type?" Qingmi Ruri thought for a while and felt that what Takeshi Nanahara said made sense. The previous victims did not have many resistance wounds. It was most likely that they were attacked by a sneak attack and had 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. He was indeed very cautious and had strong self-control when committing the crime.

As for whether you have X ability...

Thinking about it now, it seems that those with X abilities do not necessarily have to invade their victims. There seem to be several serial killers in the United States who commit crimes specifically to eat people, and some of them perform sacrifices to worship Satan. There is a certain degree of The elements of black magic were in it, and it didn't invade the victim.

She thought for a while and then asked again: "But how do you explain his disappearance for five years? Your theory sounds like the murderer is a normal person."

Takeshi Nanahara said with a smile: "Is this it? Big changes suddenly occur in normal life, such as falling in love and getting married. After a period of happy life, my heart is very fulfilling and I have not committed crimes again. But recently, there have been big changes in life again, such as divorce. And so on, the heart enters a state of emptiness, and then comes out to harm others, what's the reason for this?"

Qingjian Liuli lowered his head and thought about it, and felt that it seemed to make sense. He couldn't help but hesitate and said: "Are you right or is he right? Both of you sound reasonable!"

Takeshi Nanabaru laughed and said: "That's why I said that it's hard to say this kind of thing. Everyone speculates based on intuition and experience. No one can prove that their speculation is correct until the murderer is found."

Well, the psychological portrait of criminals is actually very inaccurate at first. It relies entirely on the sample data and intuition compiled by the "drawer" himself. However, the data and intuition compiled by him... are actually very biased, and most of the time have no reference value at all. , until computers began to be widely popularized, the Internet came online, and big data became available, the accuracy rate barely reached an acceptable level.

Prior to this, criminal psychology profiling was actually more of a gimmick to defraud funds. The main reason why it was rumored to be so amazing was survivor bias. If you encounter it once in ten times, you will be amazed. It has been adapted into TV series and movies. And the nine times that failed... most people don't know about it, nor do they care.

He briefly explained to Qingmi Ruri the dilemma of criminal psychology profiling at this stage. Qingmi Ruri, Okuno Taiji and Hidakaji suddenly realized that the current stage of criminal psychology profiling is purely based on luck. Good luck can help a lot, and it will be a direct blood C. It was bad luck and wasted time. The police searched for a year but could not find the murderer corresponding to the portrait.

The emerging technology was indeed unreliable. Qing Jian Ruri was a little disappointed, but immediately asked Takeshi Nanabaru: "Then why do you want to see the criminal files from eight years ago?"

"Of course we are seriously looking for clues related to the murderer." Takeshi Nanabaru touched his chin and muttered, "Seven years ago, it may not have been the first time the murderer committed a crime. The six current cases are exactly the same. The committing methods are too mature. There is no process of correction and improvement, which doesn’t make sense. I want to see if there are any semi-finished products.”
