Lu Nan and I spoke at the same time, which made Zhao Da very happy, and he asked us what we could do. I was not humble and explained directly. The murderer obviously chose G City to commit the crime, and the suicide forest was used as the location of his crime, and people with moral problems were the targets of his crimes, but after all, this kind of group of people is too large, and it is almost impossible to directly determine the scope.

The solution that Lu Nan and I came up with was to further shrink this group of people. First of all, in order to hide his identity and traces, the murderer will inevitably not investigate in depth on a large scale who has moral or even legal problems, but he will not be held accountable.

This kind of people, first of all, must be notorious, at least the neighbors know that they are morally corrupt. This provides a relatively large premise for our scope locking. To further identify the group of people who are likely to continue to commit crimes, other methods are needed. What we have in mind is that by surveying the terrain.

First of all, this kind of people can't be too far from the suicide forest. Hypnosis, although magical, but after all, it is a human consciousness, and no one can guarantee that the hypnotized victim will not be stimulated by loud noises and wake up suddenly on the way to the suicide forest.

In this way, the success rate of the murderer will be greatly reduced. Therefore, these people must not be too far away from the suicide forest, and the longer they go to the suicide forest, the more accidents may occur. This basically excludes some remote places in City G, and most likely, it is the crowd in the city.

Zhao Da listened, and immediately flipped through the file, and sure enough, he found that all these people who died lived in the city.

I continued: "Liu Jia said that being hypnotized, only the consciousness is blurred, some senses have not disappeared, most of these people, they go on foot, or take a taxi, they have not lost their basic ability to talk, just like the hypnosis of Xiaogang before. However, so many people have died, indicating that the murderer has also studied the route. ”

Lu Nan nodded, agreeing with what I said, and he continued with my words: "So, the area where the victim is located, on the road to the suicide forest, is not necessarily inaccessible, but it must be a relatively deserted route where the traffic will not be congested. "Through the investigation of the route, we can further exclude the scope of some downtown areas.

Zhao Da held the file in his hand and immediately began to check it. Soon, he slapped his thigh: "Professor Li, Captain Lu, you guys are really gods!" The area where the deceased was located, on the road to the suicide forest, was indeed a relatively deserted section. Zhao Dayi was excited, and said that he would send someone to find out all such areas.

I waved my hand and told him not to worry, because the range could be further narrowed. Zhao Da immediately calmed down, he sat down, waiting for us to continue speaking. Lu Nan smiled: "After my head was opened, I found that it was not particularly difficult to shrink the area. When a murderer kills, he can not appear, but the murder weapon used to kill must still exist. ”

The murder weapon mentioned by Lu Nan refers to pesticides, sleeping pills and other drugs that can cause death. The murderer's method of hypnotizing the victim to commit suicide is also regular, and Lu Nan concluded: The means of suicide are relatively soft. The word soft is also relative, Lu Nan regards the use of cold weapons, hot weapons and other killing methods as violent killing methods, and the killing methods such as taking drugs as soft killing methods.

"That can be explained." Liu Jia interjected: "If you use a more drastic suicide method, such as stabbing with a knife, etc., the hypnotized person may wake up because of severe pain, and if you wake up in time, you may not die, and hypnotic murder will inevitably fail." With drugs, it is unlikely that the hypnotized person will wake up, and he may not be able to get out of the hypnotized state until he dies. ”

Liu Jia's words reminded me of Zhu Li's suicide. When Zhu Li was mentally ill, he suddenly wiped his neck with a fruit knife, and in the end he was crazy until he died. Liu Jia can be regarded as a positive denial that Zhu Li's suicide was due to hypnosis, my head hurts a little, and the mystery of Zhu Li's death has not yet been solved.

Among the gangs behind the scenes, there is a hypnotic master, and the hypnosis method is very magical, but all the mysteries cannot be involved in hypnosis, nor can all the cases be imposed on the hypnotic master. Because there are some things that there is absolutely no way to do with hypnosis.

Lu Nan's words made me temporarily put aside the mystery of Zhu Li's death.

"The case of the suicide forest was not completely blocked from the people, and almost the entire G city knew that there were people who went to the suicide forest one after another to commit suicide, and they committed suicide by taking pesticides or sleeping pills. Now, without the need for police appeals, residents are afraid to put pesticides and sleeping pills in their homes. Lunan said.

Except for some farmers or people with serious diseases, these things must be kept at home, and no one else dares to put them away. Because no one knows if they will be the next dead in the suicide forest. I nodded and continued with what Lu Nan said: "However, the pesticide market will not be closed because of this. ”

Sleeping pills are relatively difficult to prescribe, because they are prescription drugs, so the previous deceased, who committed suicide by taking sleeping pills, used sleeping pills at home. If the deceased went to buy it himself, it was generally to buy pesticides. The murderer used hypnosis to make the deceased go to buy pesticides in a daze.

"Therefore, there must be shops or vendors selling drugs that can be used to commit suicide near the homes of such residents, otherwise, it is easy for him to fail and unrealistic to hypnotize the deceased to take a long detour to buy such drugs." I said.

Zhao Da finally got his senses, and he patted the back of his head: "In other words, if you combine all these characteristics you said, you can determine the next person who the murderer may kill?" ”

I nodded: "Pay special attention to some people who are small in the family, or some people who are left behind in the family." ”

If there are many people in the family, the murderer may be disturbed when he is on the phone with the victim. Zhao Daqian thanked him and immediately said that he was going to send someone to investigate, and then lock down a part of the area. Lu Nan and I didn't object, but told Zhao Da that it must be done in secret, and if the murderer discovers the abnormality, our actions will be ruined all at once.

Zhao Da nodded and walked out excitedly.

Lu Nan looked at Zhao Da's back and sighed: "At this time, I can only trust him." ”

I just smiled: "The quality of the police force must be improved slowly. Before it is improved, it still has to be used. ”

I asked Liu Jia if she had any suggestions, and after thinking about it, Liu Jia suddenly made a very bold decision: she said that if the police really locked the area and were able to monitor the call at a critical moment, she wanted to talk to the murderer directly. We were all slightly stunned, Liu Jia was preparing to have a head-to-head showdown with that hypnosis master.

I immediately refused: "Liu Jia, this is not a good way. ”

The previous police said that the resident who received the call said that the other party was a female voice, and this hypnosis master was likely to be a woman, after all, a person like Moyin is not something that can be casually had.

Liu Jia: "But the murderer has not appeared, and it is very difficult to catch him." ”

I understand what Liu Jia means, she wants to talk directly to the other party, trying to ask where the other party is and ask the identity of the other party through anti-hypnosis. Once they officially talked, the duel between hypnosis officially began, and this duel was destined to be a collision of stratagem and stratagem, an alternating battle between psychology and hypnosis.

I still objected, I remembered the scene in my dream, I was afraid that Liu Jia would be hypnotized by the other party and lose her life.

Jiang Jun frowned, and after careful consideration, he sighed: "Professor Li, Liu Jia may be the only person who can know the identity of the other party, let her try." ”

Seeing that Jiang Jun was also so stubborn, I hesitated.

After a long time, I nodded: "Let's talk about it later, if the person who answers the phone is different from the person the murderer expects to find, the murderer may hang up the phone directly." Unless, the next person he wants to kill is also a woman, and we try to get you to answer the phone as quickly as possible, before the victim answers the phone, which is difficult. ”
