"The victim is 28 years old, single, 1.69 meters tall......"

Kamio Kaede muttered with his cheeks raised, "Looking at the photo, the figure and face are quite outstanding, leaning forward and backward, and they are still single...... Now the female white-collar workers in the island country don't even have time to talk about a vigorous love? However, judging from the background information, although she is single......"

"It does not belong to the category of high-risk victims, and the murderer followed and killed, not because she was single and alone." There is a return road in Kitamura.

"Well, although this girl is single, she lives with her parents and is not a girl who rents a house alone. When she came home from overtime at the newspaper office, she also texted her parents to inform her, but the girl did not see her parents for the last time and died on the way home. ”

Kamio Kaede flipped to the next page, "The dossier shows that the place of death is in the stairwell of the safe passage of the underground garage A2-A3, just in the center of the elevator and the parking space of the distant mountain Qixu, that place is not monitored, and the forensic doctor determined that it is the first eucalyptus scene according to the traces of the scene." ”

Kamio Kaede looked at the file and analyzed it, it was about 10:35 p.m. on March 11, Yuanshan Qixu drove to the underground garage of the Sky Garden Community, and after the parking was locked, she took her handbag and stepped on high heels and walked in the direction of the elevator.

And at that moment, a pair of evil eyes were secretly peeking at her in a dim corner, and when Nanao Yuanshan walked between the A2-A3 passages, the murderer followed her, covering her mouth and nose and holding the other party hostage with a knife.

In the following period, the killer openly tore her clothes in the corner of the safe passage and violated her from behind.

Judging from the direction and traces of blood droplets at the scene, Yuanshan Qixu had fiercely resisted, but the murderer brutally stabbed her body three times, that is, these three knives, which made her lose the strength to resist, and she could only watch the murderer do evil.

The fatal wound was in the neck, and the murderer cut the trachea with a knife into the carotid artery, giving Nanao Yuanshan a happy death, and did not let her die slowly while waiting for blood loss.

According to the forensic examination, the fatal knife was also cut by the murderer with the back position, and it is very likely that it was caused by the murderer during the sprint at the end of the violation.

"After Yuanshan Qixu was killed, the murderer calmly left the scene, but he never showed his face under the surveillance, did not clear the traces of the scene, and did not take away the property in the girl's handbag, the only thing he lost was a jade ring in his hand, and the rest was not taken, as if he simply came to vent his surname." Kitamura said on the side.

Kamio Feng nodded, on the file, the liquid, hair and fingerprints in the pool of blood left by the murderer at the scene are all very clear and clear evidence of the crime, in short, he can be convicted of any random item, but the other party walked away so swaggeringly.

Kitamura asked, "What do you think?" ”

"If this guy is not a megalomaniac, he is a novice, and he may have some anti-detection awareness, such as knowing how to hide from surveillance, knowing how to drag the distant mountains to a corner where no one is around, of course, these may also be what he learned from watching movies......

But the murderer has only learned the surface, the criminal experience is seriously expensive, and there are so many traces left at the scene, and he doesn't clean it up, he is very confident that he will not be caught by the police? ”

"It may be the first time to commit a crime, and I am emotionally nervous, or after killing someone at the crime scene, my psychological will collapses and I regret it, so I fled in a hurry." Kitamura explained.

Kamio Kaede hummed, barely making sense, "The age is not so sure, between twenty and forty years old?" Monitoring Taimo Lake, and there is no face, it can only be seen that the murderer is medium to thin, judging from the wound on the neck of Qixu in the distant mountains, the murderer is holding a weapon in his left hand to hurt people, and he should be a left-hander.

may have known the victim from afaryama Qixu, or had contact with him in life, such as nodding his head, picking up a courier, borrowing the same book in the library, and so on...... Because of this contact, the murderer had evil thoughts about the distant mountains and Nanao, and put this surname fantasy into practice.

Maybe it's a resident of the Sky Garden, a security guard at the door, a next-door neighbor, or a cleaner at the property...... Judging from the file, the murderer was able to evade most of the surveillance, and apparently knew the structure of the underground garage in the Sky Garden Community. ”

Kitamura said: "The conclusion of the investigation on the file is similar to what you said, after the scandal, the police department has conducted a large-scale investigation of the friends, colleagues, and neighbors of Yuanshan Qixu, including community security guards and properties, but unfortunately, there is no exact suspect so far, and those who are slightly suspicious have finally been acquitted because of various alibi." ”

He continued: "There were several subsequent deaths in the jurisdiction, and the dead were both male and female, but the final investigation showed that the murderers were all left-handed. This matter is quite strange, the probability of left-handed people in our country is only 5%, and there will never be several left-handed murderers one after another, right?

So the store asked us to investigate temporarily, and they will also send a crime analysis expert to help solve it. ”

"Crime profiling expert?" Kamio Kaede touched his head, "What's the use, wouldn't it be another returnee who has read foreign ink to come over and point fingers and talk on paper, right?" We've got one ......."

"The person who came this time is different, the other party is a detective from Osaka Prefecture, known as the savior of the Kansai police, and he has been assisting the Osaka Prefecture police to break the eucalyptus since high school, and he has achieved a lot of results.

Last year, he was invited by the Metropolitan Police Department to study at the Central Police University, and now he is a general officer of the Criminal Psychology Department of the Metropolitan Police Department's Scientific Search Research Institute. ”

Kamio Kaede couldn't help but laugh, and said: "Broken eucalyptus doesn't send some experts or professors to sit back and relax, the criminal psychology department is originally a criminal investigation auxiliary means, at most it plays a role of assistance, this store sent such a person over, what role do you want him to play, commander or staff officer?"

We have all learned the allusions of Zhao Kuo talking about soldiers on paper, and more than 400,000 Zhao Jun were killed by military experts. ”

Kamio Kaede feels that only by doing the following three things in the discipline of criminal psychology can it be regarded as truly getting rid of the false name of talking on paper and being able to participate in the investigation of criminal cases.

First of all, the criminal profiling features provided should be substantiated, secondly, the reasoning process is meticulous, no flaws, and there is a unique thinking logic, and finally, the suspect target is not fixed.

There are many bases for the characteristics of the criminal profile, such as the murderer's gender, height, weight, occupation, hobbies, living range, behavioral habits, marital status, religious beliefs, education level, etc., which can all be used as profiling characteristics, and it is necessary to ensure that the criminal investigators can find specific suspects.

Similar to inferring that the murderer suffers from 'paranoid schizotypal personality disorder' or 'sociopathic schizophrenia', this kind of incomparably high-minded, obscure and esoteric professional words belong to Zhao Kuo's type.

Have the searchers find a hundred suspects suspected of having this symptom, then line up to ask them about their childhood experiences, who has wetted the bed, who has set fire to the villager's house, who has often abused small animals, and then labeled them and continued to the next question with the encyclopedia of criminal psychology......

Regardless of whether the murderer can be found, it is certain that this kind of expert will be scolded to death by the police.

For example, when you see Nanao Yuanshan die in March and was stabbed three times, you will decide that the murderer likes the number three, thinking that it represents a special meaning, and then concludes that the murderer is an admirer of Pythagoras or a three-second man.

Please, this is not the number murder that shocked Phobore, there are no obvious numbers to mark the crime, and it is not the chief disciple of the devil, Richard, who left an inverted pentagram at the crime scene for demonstration......

This kind of nonsensical speculation is purely a child's jumping thinking, which has no reference basis at all, but is suitable for some brainless soap opera routines.

Finally, the target of the suspect is not fixed, even if the so-called experts determine the suspect's psychological characteristics, behavioral characteristics, and physical characteristics through various clues, and even accurately profile the suspect as a middle-aged Slavic and wearing a double-breasted suit, as Bruscher did......

But that doesn't rule out other suspects entirely.

Because reality is not static, just like pi, even if you have calculated to tens of trillions of decimal places, you still don't know what is behind, and criminal investigation will always be full of all kinds of conflicts and accidents.

Kamio Kaede finally said: "If this expert from Kansai really has two brushes, then it would be the best, but if it is just to gild and shut up criminal psychology, then we can't listen to him." ”

Kitamura smiled, "There must be two brushes, and the person sent by this store will not be a rice bucket." Okay, when the experts come, you can slowly get in touch and run in, and now the focus of the criminal class is all on the serial eucalyptus.

Especially the eucalyptus in the hanging garden, the first eucalyptus suspected of being committed by the murderer, the eucalyptus technique is unfamiliar, and there are many traces, which is the easiest point to break through.

At present, the Metropolitan Police Department's database temporarily compares the fingerprints and hair in the pool, which may not be a habitual hand, and there is no criminal record, so the only way to find a needle in a haystack is to expand the scope of the search as much as possible. ”
