Chapter 25 Chapter 2 Cannibal Psychology

Because the clues are really limited, especially the identity of the victim cannot be confirmed, it is difficult to effectively carry out the investigation of the case.During dinner, Gu Feifei communicated with Han Yin, hoping that he can make a rough criminal profile report based on the information he has so far. Whether it is for the criminal or the two victims, how much can he narrow the scope? How many.So Han Yin returned to the hotel room after dinner and began to draft the report. Summarizing the previous cases of killing and eating meat due to abnormal psychology, they can be roughly divided into three types: the first one is that eating human flesh and internal organs can nourish the body, such as the number one perverted murderer in Korea, Yoo Yong-chul, he confessed in court that he believed that Cannibalism can be refreshing, so he has eaten the internal organs of four victims; the second is sadistic, such as Andrei Chikatilo, known as the Russian "Red Ripper", who claimed that the victim The painful breathing of a person can arouse his sexual desire even more, so that he will bite off the victim's tongue and swallow it in his stomach; the third is to seek to control power, such as the German cannibal demon Armin Meiwes, who Living in a single-parent family when she was young, her mother has a strong and violent personality and a strong desire to control, which makes her weak and inferior and lacks assertiveness. At the same time, due to the lack of male role models in her life, she is gender-neutral and extremely insecure.Psychologically suppressed the resistance to his mother, and desperately longed for fatherly love, which led him to have a love for the same sex, and eventually ate a man.It is worth noting that Armin Meiwes chose to cut off part of the man's body to eat while he was still conscious. From this point of view, he also has sadistic characteristics.To sum up: the first type belongs to hallucination and delusional crimes, and the second and third types belong to sexual crimes.

In previous murder cases, it was extremely rare for the murderer to choose sedative hypnotic drugs to kill. Although "Triazolam" has the characteristics of rapid absorption, quick onset, and strong effect from the perspective of loss of consciousness, the lethal process is relatively slow. It is much longer, and it may even require the help of alcohol to be completely lethal.However, this may be exactly what the murderer needs in this case. He should really enjoy the situation where women still have a certain degree of consciousness but can be at his mercy.But even so, he still chooses to cut up the victim's body for food and rape the corpse after the victim is completely dead, which fully demonstrates his extreme inferiority complex and necrophilia. Of course, this undoubtedly belongs to the category of sexual crimes.

Theoretically speaking, there are relatively many ways and channels for women to release their sexual repression, and most of their sexual desires are passive and receptive, so female serial killers who commit violent crimes due to sexual motives are very rare; The sophistication, experience and strength of killing and throwing corpses are beyond the reach of a woman.It is not difficult to conclude from the above analysis that the murderer is a man who kills and eats meat in pursuit of a sense of control to obtain sexual satisfaction, that is to say, he is also a control freak like Armin Meiwes.However, unlike Armin Meiwes, the murderer in this case did not show the characteristics of abuse, but more of a "possessive" mentality. Of course, from his point of view, it was a kind of "love" Performance.The whole process of crime is actually the pursuit of a love that will never be lost-eat them, and he and they will become one, and they will never be separated!

In addition, judging from the characteristics of the case, the murderer chose the same place to dump the body twice was fully premeditated, which is in line with the characteristics of a "geographically stable" killer; however, the murderer cooked human flesh, and the victim was naked when dumping , and the behavior of hiding relics, this series of behavioral characteristics are consistent with the characteristics of "geographical mobile" killers.Therefore, if analyzed from the perspective of "criminal profiling of geography", the murderer in this case is a hybrid between the above two types of serial killers.Considering it all together, Han Yin believes that the background characteristics of the murderer may be as follows:

Male, single, never married, mature in age and experience, well educated, engaged in technical jobs.The way he chooses to kill, in addition to reflecting his desire to seek control, may also be related to his weak stature or some kind of physical disability (usually poisoning murderers are more common in women).This has also resulted in his excessive inferiority complex and introverted personality, especially his lack of ability to communicate with women, resulting in the lack of the existence and care of female characters in his growth process.Even due to external reasons, he may often be ignored by his own mother.He may have been separated from his mother since childhood, or may live with his mother, but the relationship between mother and child is very tense.His external performance will give people a feeling of peace and humility, but his heart is extremely lonely and depressed, with an unknown dual personality.

The murderer should live alone, and the place where the corpse is thrown should not be too far from his residence, because he needs to feel the presence of his "lovers" all the time, and it is also convenient for him to visit the place where the body is thrown to relive the pleasure. The murderer's choice of victims is not random, it must be carefully selected, and it is certain that some quality of the two victims attracted him, and he did not know the victims before, or had only occasional contact, but not There will be intersecting interests... This night, Gu Feifei also fought intensely all night long, hoping to narrow the scope of the investigation of the victims through the evidence of the corpse.

First, she will restore the appearance of the first victim.The procedure is roughly as follows: First, use a CT machine to scan the victim's skull in all directions, and input the scanned images and data into the cranial phase reconstruction system; then use professional software to calculate the thickness of the cranial and facial soft tissues, obtain the ethnicity and bone age data; then add bone age features and soft tissues such as muscles and blood vessels to the three-dimensional skull; finally, on the facial prototype just created, construct facial expressions and modify facial features, and finally get an appearance close to the victim.Of course, behind this technology is a powerful database that collects the facial features of 56 ethnic groups in China.

This work took more than two hours. When Gu Feifei got the reconstructed photo of the victim's face, she believed that it was at least 70% similar to the victim's real face. As previously analyzed by Forensic Li, the two victims have been missing for several days and no related reports have been seen. It is estimated that they are not locals, so the restoration of their appearance is only the first step.The next step is to work hard on the corpse to find a breakthrough.Fortunately, the hair of two victims can now be harvested. In forensic science, hair is a very important physical evidence. It can faithfully record the life information of each person. This information can be stored for months or even years. Even if the hair leaves the body, the information will still be retained.Therefore, by detecting the information stored in the hair, various factors such as a person's eating habits and living environment can be inferred.For example, 85% of the hydrogen and oxygen isotope changes in hair are determined by local drinking water, then analyzing the length and growth time of hair can determine the place where the research subject lived in recent weeks or even years...

Through mass spectrometry analysis, at dawn, Gu Feifei obtained a set of information: the hair of the two victims contained a large amount of ethanol and methanol, and ethyl acetate, ethyl propionate, ethyl butyrate, etc. were also detected in the hair Esters and aniline compounds, etc. Ethanol and methanol are the main components of industrial alcohol, ester compounds are the main components of alcohol flavors, and aniline compounds are the main raw materials for artificially synthesized pigments, so these seemingly numerous compounds are actually one thing—fake foreign wine. Regarding the production and sales of fake foreign wines, domestic media have reported many times: Some unscrupulous businessmen, driven by profit, blended industrial alcohol, flavors and pigments to produce inferior wines, and sold them as branded foreign wines to entertainment venues.This kind of incident has occurred in various provinces, cities and regions in China, and it has been repeatedly banned. Therefore, Gu Feifei speculates that the two victims should often hang out in local bars, nightclubs and other entertainment venues during their lifetimes.

Later, Han Yin and Gu Feifei touched their respective analysis results. Gu Feifei pointed out that the victim should frequent various entertainment venues, while Han Yin pointed out that the murderer is incapable of meeting the person he likes in these places.Comprehensive consideration: If the girl is willing to go with the murderer, it can only be due to the role of money, which means that the two victims are likely to be hostesses in entertainment venues. With regard to the range of backgrounds of the victims pointed out by the support team, the Yunhai City Public Security Bureau immediately made relevant deployments. All branches and police stations in the city launched a large-scale investigation operation on bars and nightclubs in the jurisdiction that had a history of engaging in pornographic services. A few days later, the two victims The identity of the author was finally confirmed.According to the analysis of the support team, the two victims were indeed foreigners, and they were engaged in accompanying wine service in nightclubs and KTV Liange City before they were killed.

The police seized the nightclub and KTV Liangecheng, and controlled the owners and service personnel of the two entertainment venues.After careful recollection, they confessed that the two victims both provided "sit on stage" and "go out" services, and did not reappear after leaving the nightclub and singing city on the evenings of August 19 and September 25 this year respectively.The same thing is that both of them suddenly asked the boss for leave during work, saying that they wanted to meet an important friend and left early.Check the two-person call records. The last call came from two different numbers. Both numbers have only one call record. It is not difficult to judge that the murderer bought a disposable mobile phone card to call. Based on the above information, on the one hand, the police traced the selling point of the mobile phone card, hoping that someone could recall the appearance of the purchaser; With the cooperation of the clerk, an investigation was carried out on some customers who had patronized the victim; moreover, it was necessary to visit the major taxi companies in the city and ask the taxi drivers who often carried passengers near the two entertainment venues to see if there were any The driver drove the victim during the time of his disappearance; in addition, the police also searched the rental house where the two were renting, but found no useful clues. While tracing the murderer based on the victim's information, the investigation of the murderer's residence is also being actively carried out.Following Han Yin's suggestion, the Criminal Police Team took the "Science and Technology Eco-City" near Nanshan Lake as the main investigation area, focusing on male households living alone.However, in practice, it is not so easy. At present, only about half of the planned residential quarters are put into use in the eco-city, and a considerable area of ​​real estate is still under construction.Therefore, although the entire residential complex is positioned as a mid-to-high end, the actual situation is that the community cannot be closed and managed at all, there are multiple access routes, and the security monitoring is not in place.The bigger difficulty is that the identities of the residents who have moved in are very complex. Some are from the local area, and there are also many relocated households from other places. Most of them are renters working in the science and technology park.And because it is an emerging urban area, the construction of neighborhood committees and community services is not yet complete, and the police station is not very clear about the situation of the personnel in the area under its jurisdiction. It takes a lot of time and energy to check each household, so the progress is quite slow. But what the police didn't expect was that just when they were trying their best to find the trace of the murderer, a special "gift" came quietly.
