(Today's second update.) In order to follow up a more thrilling and suspenseful plot, Bai Qi needs everyone's various collections and recommendations! ）

Mao Qiang also had nothing to do about Wu Dawei's reliance on the old and selling the old, so he glanced at Liu Xiaolin comfortingly, and said: "Experts, do I think the seven deadly sins left by the murderer are related to the records in the Bible?" ”

It is customary to call it the "Seven Deadly Sins" in China, in fact, it should be called the "Seven Sins", which is the first to list the various evils of St. Thomas of the Dominican priest in the 13th century, and the last is summarized by the Catholic Church, according to the degree of violation of love, in order: arrogance, jealousy, anger, laziness, greed, gluttony, and **.

There have been serial killers in Europe and the United States who have used the Seven Deadly Sins as the motive for killing, and many movies have filmed similar scenes. But in China, this kind of thing is the first time everyone has encountered it, and no one has any experience.

Wu Dawei and the other two experts around him discussed a few words in a low voice, and then said: "According to what you just said, the first of the seven deadly sins should be arrogant, could it be said that the deceased offended the murderer before his death?" That's why he was killed so brutally! There is some truth in your statement, in this way, Xiao Mao, you immediately mobilize your manpower to find out the identity of the deceased, only after understanding the identity of the deceased, can we call the family of the deceased for questioning, and can find out the murderer from the interpersonal communication of the deceased. ”

Wu Dawei turned around with emotion and asked the two people around him: "Grandma is a bear, why haven't we met any serial killers before!" If you meet him, see if Lao Tzu doesn't skin him! "Wu Dawei is very stupid.

Mao Qiang was embarrassed, he just wanted to talk about something to relieve Liu Xiaolin's embarrassment, but he didn't expect to take the matter on himself. In fact, not to mention other people, it is Mao Qiang himself, who is also dissatisfied with the expert group sent by the provincial department this time. Three people came, two of whom were Wu Dawei's students, and since they sat in the conference room, they supported whatever Wu Dawei agreed; If Wu Dawei refuted it, they objected.

Wu Dawei himself is not easy to say, Mao Qiang admits that he is, oh, it should be said that he used to be a criminal investigation expert. The problem is that with the improvement of the law and the progress of the times, many of Wu Dawei's previous detection methods are now outdated.

At that time, they didn't care about thirty-seven twenty-one, as long as it was a suspect, they were arrested and locked up first, and interrogated slowly, during which there might be forced confessions, induced confessions, or something, not to mention.

Now that the case is solved, the first sequence is to pay attention to physical evidence, and without physical evidence in hand, it can only be empty talk.

Mao Qiang was generalized, as a team member, Wang Lei couldn't be indifferent, Wang Shui'er and Yang Qian were still waiting for him, Yang Qian's anxious look from time to time Wang Lei could see it clearly.

He also learned from Liu Xiaolin to raise his hand and ask to speak. Wu Dawei nodded in an old-fashioned manner, Wang Lei looked left and right, and explained cautiously.

Serial killers have been discovered in various parts of the country in recent years, and there were very few in the past, after all, when there was not enough to eat, people's psychology could not be considered more.

Most people always think that a serial killer must look like a madman or a madman, with low moral character, but in fact it may not be! Most of the serial killers are no different from ordinary people, even very charming, and have noble sentiments or strict moral sense, and even there are many highly educated people, which also gives people the illusion that they are easy to get close to. Simply put, the vast majority of serial killers barely associate them with their actions until they are caught.

Of course, there are not without serial killers who are already seriously mentally ill, or very aloistic, and live in near isolation.

Speaking of this, Wang Lei looked at Wu Dawei and the three of them with his spare eyes, and the three of them were basically listening patiently. Wang Lei gave an example: "For example, the very famous serial killer Ted in the United States? Bundy, a Chinese student at the University of Washington in Seattle, worked with Republican Senator Locke Brown? Feller ran to volunteer before returning to college and graduating magna laude from the University of Washington in Seattle, where he worked at the Center for Suicide Prevention. He had two successful escapes from the county jail before his last arrest in February 1978. After his arrest, he completely denied his crimes, and it was not until more than a decade later that he confessed to committing more than 30 murders. However, the true number of victims is still unknown, and the FBI Behavior Analysis Office estimates that Ted? Bondi has killed at least 100 people in the past 10 years. ”

Everyone in the room gasped, they had never known that a murderer could be so fierce. Wu Dawei couldn't help asking: "Then what kind of Di caught it after the most lusk?" ”

Wang Lei nodded and smiled slightly: "I caught it." In 1989, he was executed in the electric chair in Florida, USA, because of his most conclusive murder. ”

Wu Dawei began to be attracted by Wang Lei's words, and took the initiative to throw Wang Lei a cigarette and said, "Everyone be quiet, let Xiao Wang continue." Alas, we just didn't have enough knowledge back then. ”

Wang Lei drank his sip first, and after saying so much, his mouth was dry. Lighting a cigarette, Wang Lei spoke unhurriedly.

The biggest characteristic of a serial killer is that it is "fixed", and the motive for killing, the killing pattern and the target of the killing are not easily changed, because the killing behavior of the serial killer is to satisfy a fixed ideal goal in his mind.

The content of this goal may be related to the sexuality and rights of one or more people, or even survival, or it may be purely moral and cultural concepts, but the content is distorted and out of touch with reality. Serial killers are like ordinary criminals, they also do everything possible to explain their actions, and they have to recreate their goals every once in a while, and the killing pattern is almost fixed and not easy to change.

According to the FBI Invited Scholar Helen? Morrison's research confirms that the key to a person's development into a serial killer may be the background of cultural education, society, family, economy, religious beliefs, etc., or it may be based on the disconnection between cognition and reality due to the disorder of human emotional development, and the inability to control oneself due to dreams and inability to control oneself.

Stopping to extinguish the cigarette butt and drinking half a glass of water again, Wang Lei raised the doubts in his heart: "If the murderer left a warning of seven deadly crimes, then according to the FBI's behavioral analysis guidelines, the murderer should kill 7 people in a row, and each time he uses a murder method related to the crime." What I don't understand is - first, why does the murderer kill a person every 36 hours? On the way here, I asked my friend to help me check the relevant passages of the Bible, and the seven deadly sins have no time to be related to them; Second, why did the murderer use seven different methods of violence on a person, which is also a bit different from the discussion of the seven deadly sins. ”

Whether it was the three experts or the members of the serious crime team, everyone was silent, these two questions were too difficult to answer. Perhaps, only by catching the murderer and doing a psychological analysis of him can we figure it out, Mao Qiang thought in his heart. However, this is a classic case, if you can catch the murderer before he kills next time, maybe the entire case detection process can be written into the textbooks of the Public Security University, hehe, he will be famous in history, Mao Qiang showed a strange smile on the corner of his mouth.

Wu Dawei found that he seemed to have come to the wrong place this time, how could he meet such a tricky case. He finally figured it out, because there were so many criminal investigation experts in the provincial department, they were reluctant to come after reading the report materials of the Linhai Municipal Bureau, so the director of the department arrested an old man like himself who was half buried in the loess.

"Grandma's bear!" Wu Dawei hated in his heart: "Lao Tzu has been shrewd all his life, and he has entered the crematorium for a long time!" ”

Holding back his emotions, Wu Dawei spit out a smoke ring, and pretended to be calm and said: "Xiao Mao, I think so, your serious crime team will go back to the office first to concentrate and report a plan, and the three of us will have to wait for the forensic report to come out with some suggestions before we can confirm it." ”

The first thing he did when he walked out of the conference room, Wang Lei took out his mobile phone and called Yang Qian in the car below: "Grandma, you know that I am in a meeting, how dare I text you back?" We're back in the office now, and we still have to discuss, it's a very urgent matter, and there is a time limit. It seems that you can only talk to you about your affairs at night? Why don't you tell Wang Shui'er that everyone will have dinner together in the evening? Okay, okay, I've got a treat, okay? ”

Hanging up the phone, Wang Lei smiled bitterly, why did everything come to his head. Lin Long's case has not made any progress at all, irritable, Wang Lei rubbed his face, it is impossible for him to leave everything behind, resign to investigate Lin Long's case, without this police identity, it is very inconvenient to investigate anything.

didn't dare to think about it, Wang Lei followed everyone back to the office, Mao Qiang knocked on the table, and asked, "Whoever has a way to talk about it, right?" It's only a little over a day, and I can't afford to drag it out. ”

Li Yuan looked at Liu Xiaolin, the two shook their heads, Yuan Feiteng looked at Wang Lei, and the two shook their heads. Mao Qiang's heart was cold, Wang Lei had no choice, and it was estimated that he couldn't think of a better idea.

He thought for a moment and said, "Since everyone is helpless, let's follow the conventional method." Li Yuan, all four of you went to the development zone, and asked the development zone police station to assist you, with the place of death of the deceased as the center, a radius of five kilometers, and began to post the deceased's height, clothing, and other investigation notices, in an effort to find out the identity of the deceased. I am responsible for the liaison and coordination between the Group of Experts and you, and that's it, action. ”

Yang Qian and Wang Shuier found a good restaurant, ordered good dishes, and waited for Wang Lei. This is a long time to wait, if Wang Shui'er hadn't bought the order first, it is estimated that the owner of the restaurant would have called the police and said that there were two women here who ate the overlord meal.

After the table was hot three times, Wang Lei finally arrived, and the three of them gobbled up for half an hour, Wang Lei put down his chopsticks and stretched his waist: "I'm so tired." Yang Qian, can you tell me about you? ”

Seeing that Wang Shui'er looked unfazed, Wang Lei estimated that the two women did not know how much information they exchanged in the afternoon. Yang Qian stuffed a piece of green vegetables into her mouth, chewed it a few times, and then began to talk about everything that happened the night before.

Although Yang Qian thought that she didn't care, she still avoided the scene of tempting Li Dou, saying that she and Zhao Hua were preparing to take Li Dou in the hotel room.
