Lu Nan's face became even more exciting, and he suddenly asked me with great interest, what my guess was. I remember Lunan telling me before that he used the trick of trapping a murderer to intercept a man who almost committed suicide in the suicide forest. Lunan had the medical examiner perform a physical examination of the man, and as a result, the hallucinogens were found on his body.

In most areas, hallucinogens have gradually begun to be classified as new drugs, which cause hallucinations. However, what kind of hallucinations can cause people to hallucinate is basically uncontrollable. Of course, this is just speculation based on what I know about hallucinogens, and before I explain, I ask Lunan if he is still a hallucinogen.

Lu Nan shook his head, he had indeed thought about it before, so he went to investigate, but the results of the investigation made him negate the possibility that hallucinogens caused so many people to choose almost the same way and place to commit suicide. I nodded and said to Lu Nan, "If my guess is correct, what you think of should be hypnosis." ”

Lu Nan slapped his thigh: "Professor Li, you are really a god, you didn't investigate, how did you know." ”

Lu Nan's praise made me feel very comfortable. When I talked to him about the Youth Federation, I didn't mention much about hypnosis, after all, it was a shame for the Shen brothers and sisters. He didn't know at all that I was speculating about the suicide case of Suicide Lin because there was a hypnotic master behind the scenes, which might have something to do with hypnosis.

I didn't say anything, I just smiled. The key to the suicide forest case is not how those who committed suicide or where they committed suicide, but a suspicious point that Lu Nan investigated: all the people who committed suicide received a phone call on the day of suicide.

According to the results of Lunan's investigation, the calls were all made from public telephone booths, most of which were public telephones in City G, and a small number were in other provinces. The closer to the suicide case, the more Lu Nan can investigate, but the longer it is since the suicide occurred, such as the suicide case that happened just after I left G City, Lu Nan can only find out one phone number at most.

Both Dr. Liu and Jia Liu have told me that there are many ways to hypnosis, and the most common way of hypnosis is through sound. To this day, I still can't calm down when I think of Dr. Liu unknowingly hypnotizing me in the research room of the Police Academy.

Hypnosis, it's terrible. Dr. Liu has been reluctant to divulge his research results because he is worried that hypnosis will be used by criminals. However, what he feared, eventually happened. Hypnosis is essentially psychological suggestion, and hypnosis through sound generally uses monotonous and repetitive sounds to make people's nerves feel fatigued.

As soon as a person is tired, it is more likely to be gradually guided by the hypnotized practitioner and fall into a state of hypnosis. Telephone hypnosis, where sound is transmitted through an earpiece, can theoretically be done. However, it is very difficult, after all, hypnosis is not a simple matter, at the beginning, Liu Jia was next door to the hotel through a monotonous voice, wanted to hypnotize me, and stole Dr. Liu's hypnotic results, she failed.

Just because it's difficult doesn't mean it can't be done. The hypnotic master behind the scenes is likely to be a person who is more proficient in hypnotism than Dr. Liu, and it is entirely possible to hypnotize people through the phone simply by using sound. Moreover, more importantly, through the investigation, Lu Nan found that when these people went to buy pesticides or sleeping pills, their speech was a little blurred, more like sleepwalking.

Lunan immediately told me that after he had this speculation, he looked up many foreign cases, and soon, he found out about the Heidelberg incident.

Before this, Lu Nan did not believe that hypnotism could be so magical that it could control people's consciousness and commit crimes. However, he is now convinced.

"If my guess is correct, every phone call received by the deceased before he died, and the call time was not short." I said to Lunan.

Lu Nan laughed: "Professor Li, you are really amazing, if you want to say who I admire, maybe only you, Professor Li, can make me admire." "Lu Nan's nature is like this, his reconnaissance ability is strong, but his shortcomings such as timidity, love of sycophants, and greed for vanity are also real.

Although I don't have a deeper understanding of hypnosis, one thing I know for sure: it is impossible to do hypnosis with sound alone without face-to-face contact. Reasoning on the other hand, if the murderer really had such superb skills, the country would have been in chaos a long time ago.

Just imagine, if the murderer can hypnotize people at once through the phone, he can call everywhere and make the society bleed all at once. It's absolutely impossible, which is why I speculate. Ronan confirmed that by further investigating the duration of the call, he found that the call that the deceased had received before committing suicide had been between thirty and forty minutes.

"Although there is no evidence, I think the murderer may have used a stranger to ploy," Lu Nan said. "The so-called stranger strategy is to use the psychology of strangers and pretend to be mature. Lu Nan gave me an example, if on the street, suddenly a stranger pats you on the shoulder and calls out your name, even though you don't know him, you will still hesitate in your heart whether you actually know this person, but you have forgotten.

Out of embarrassment, it is likely that at this time the person can only pretend not to forget and talk to him. This is how many fraud cases began, this kind of criminal method, the threshold is very low, only need to investigate the victim's name and other basic information.

Lu Nan's speculation is reasonable. If the murderer uses a stranger's strategy, then he can buy more time to talk to the victim without knowing the victim, so as to hypnotize the victim step by step. If you zoom in on the stranger's strategy, the killer may have tried other ways as well.

Such as sales pitches or taking advantage of other people's greed. It is not difficult for the murderer to get more time to talk to the victim. I asked Lunan if there had been more progress after the investigation had reached this point, and Lunan shook his head, saying that there were no surveillance cameras near those public telephones.

Although our speculated criminal modus operandi may have approached reality, Lu Nan has no clue who the murderer is. I'm not surprised, there are not many people who can compare with Dr. Liu in hypnotism, and this hypnotic master in the hands of the mastermind behind the scenes is so powerful, it is not a simple matter to catch him.

I thought about it and told Lu Nan: "Tomorrow, we will ask Zhao Da to notify the grassroots police and secretly visit the major areas of G City." ”

Lunan asked me what I was going to do, and I replied that I knew a little more about hypnosis than Lunan. Dr. Liu once said that not everyone can be hypnotized. Through my research on various sources, the results of the authoritative investigation are that there is a group of people who cannot be hypnotized under any circumstances.

Most of these people are strong-willed people, but there are exceptions. The study of hypnosis, even abroad, is only in a preliminary state. It is difficult to explain why some people cannot be hypnotized, but this phenomenon has been solved by us and provided an opportunity.

This hypnotic master, who has made so many people commit suicide in the past year, is premeditated. He acted so carefully that he didn't let the police catch the clues, so before making a phone call, he definitely wouldn't conduct an in-depth investigation of the victim, at most just the name and phone number.

If you say this, the murderer himself does not know the target he has chosen, and there is no way to be hypnotized. Probability-wise, it is highly likely that the murderer once chose someone who could not be hypnotized, and the hypnosis failed. Finding out such a person through a visit may be helpful in determining the identity of the murderer.

At the same time, the possibility of the murderer committing the crime still exists, and he may continue to hypnosis more people to commit suicide through the phone, hypnotizing and suggesting that more people will commit suicide.

Lu Nan nodded immediately, he sighed: "There are such criminals, it's really terrifying, a social cancer, what is their purpose?" ”
