When Zhao Hua rushed to the Lingnan City Public Security Bureau with the Linhai Serious Crime Team, Zhang Jian, director of the Lingnan City Public Security Bureau, led the team to wait at the gate for almost half an hour. The only person Zhang Jian knew was Han Hongfei from the provincial department, there was a series of robberies in Lingnan before, and Han Hongfei came to guide the investigation at that time. Speaking of which, Han Hongfei still has a certain ability, but he is a little arrogant.

Zhang Jian stepped forward and clasped Han Hongfei's hand: "Expert Han, hello." Thanks to the leaders of the provincial department for coming to guide our work, we will fully cooperate. Aren't these guys? Han Hongfei nodded lightly and introduced Zhao Hua and Zhou Weiguo to Zhang Jian, as for the people of the Linhai Serious Crime Team, Han Hongfei looked indifferent. Zhao Hua laughed and laughed, everyone is a peer, the purpose of coming is to solve the case and arrest the murderer, don't look at what provincial department you are sent by, if you really have Wang Lei's ability, what else is our national security going to do!

After Zhao Hua received the temporary notice from the bureau, he called to ask for instructions, and the greater role of him and Zhou Weiguo this time is to sit in charge and adjust, and to say that the investigation of this link must fall on the head of the Linhai serious crime team. Zhao Hua smiled and pulled Mao Qiang: "Director Zhang, we are here this time mainly for coordination and support, this is Captain Mao Qiang of the Linhai City Serious Crime Team, and the next few are his team members." I'm sure you've heard of it, right? ”

Zhang Jian didn't dare to slack off, even if Mao Qiang was a grade lower than his administrative level, but this time the case was complicated, and Lingnan had no clue. Moreover, in the past few years, the outstanding criminal investigators selected by the ministry at the end of the year have almost been won by Linhai, and he has also heard of the reputation of the Linhai Serious Crime Team. According to Zhang Jian's original intention, he originally wanted to directly ask Mao Qiang and them to come over to help, but who knew that the national security office in Lingnan Dao had stabbed the matter up, which caught him off guard, and made the province and city have a lot of opinions about him.

Zhang Jian is an old fritter, and he had a hot fight with Mao Qiang and them in a few minutes, and at the same time paid attention to Han Hongfei's emotions, which was basically a happy situation. The large conference room of the Lingnan Public Security Bureau was already overcrowded, and the oval-shaped circular table was full of seats, and everyone was whispering and discussing with their acquaintances.

Zhang Jian looked at the side, the office director on the side opened a few cigarettes very sensibly, and placed a pack in front of each person, and a beautiful young woman in a police uniform followed behind the director with a stack of documents, and also put a case report in front of everyone. Gradually, the office quieted down, everyone looked at Zhang Jian, and only the "hum" of the air circulation system could be heard in the huge conference room.

Zhang Jian introduced Zhao Hua, Han Hongfei and Mao Qiang to his subordinates, and for the people of the Lingnan Public Security Bureau, Zhao Hua's arrival was a big shock. Some people think that if it's not just a small poisoning case, maybe a few more people die is not a big deal, but because of the need for national security, are there other articles in it?

In short, after a round of applause, the case meeting officially began. I have to say that the basic work on the Lingnan side is still very solid, and a large number of visits and investigations and detailed autopsy reports are listed in front of everyone one by one.

A total of 11 people were poisoned, and 9 people died, and the time span was 20 days. All of them died after taking ecstasy and then taking pentobarbital again. There were two survivors who were rushed to the hospital in time because their families found out. But the problem arises again: there is one consequence of taking pentobarbital and hallucinogens such as ecstasy together – amnesia. In other words, the two survivors simply cannot provide any useful clues about locations, characters, etc. Moreover, penthiobarbital can be bought in any large pharmacy, and ecstasy is even simpler, you just need to go to any nightclub, and someone will come up to sell you, so the source of the drug cannot be found.

The Lingnan investigation report also listed a very peculiar point: none of the poisoned people had any contact or intersecting relationship with other people. These 11 people are spread from all walks of life and all parts of Lingnan, including vegetable sellers, workers, children, cadres, and merchants......

The two surviving children were a 10-year-old child, a third-grade student at Lingnan No. 1 Primary School; The other is a police officer from the Public Security Brigade of the Lingnan Public Security Bureau. After many confirmations from the Lingnan task force, neither the child nor the policeman had taken ecstasy, and it was impossible for him to have drug abuse experience! Therefore, half a month has passed, and the investigation work in Lingnan has also reached a deadlock. For this reason, the city leaders of Lingnan City were furious, and Zhang Jiancai was forced to ask the provincial department for help, even if it would affect his future career because of this reason.

After Zhang Jian introduced the basic situation, he said with a wry smile: "The main reason why we are in a stalemate is because we cannot confirm the murderer's motive for poisoning. Now rumors are spreading in the city, outsiders have left the city, and the public has quite a lot of opinions...... Expert Han, do you have any comments or suggestions on this case? ”

Han Hongfei shook his head, a little embarrassed. He is not an immortal, how can he just go to the place to look at the report and make suggestions, he muttered: "This, let's listen to everyone's opinions first, brainstorming." ”

Zhang Jian exchanged a look with several bureau leaders, fuck you, listen to everyone's opinions! How well is it said, if we have an opinion, do we need to delay until now? Didn't you come down from the provincial department to assist us? Damn, it's also an official for a long time, and it deserves to be a "brick family"!

Zhao Hua was very refreshing: "I suggest listening to what Captain Mao has to say." Mao Qiang glared at Zhao Hua, and the experts of the provincial department hinted that it was very difficult, didn't you roast our Linhai Serious Crime Team on the fire! However, looking at Zhang Jian's eager gaze and the contemptuous eyes of some Lingnan case-handling personnel, Mao Qiang was also a little angry in his heart. This is not our own begging to come to your Lingnan, if it is not for the request of the national security side, who will pay attention to you! Forget it, Mao Qiang thought in his heart, he didn't have the same knowledge as you people, he looked at the four team members around him and asked, "Which of you will come first?" ”

Li Yuan stared at Yuan Feiteng, moved his foot, kicked on Wang Lei's calf, and said without changing his face: "Wang Lei, let's talk about it." Liu Xiaolin was immersed in his own world, regardless of the inquiries from the outside world, Mao Qiang had to sigh in his heart.

Wang Lei's fingers tapped on the table, whether it was a pause, very rhythmic. He thought slowly and said, "Paul, the most famous psychologist in the world? Ekman once said in a lecture in the FBI's Behavioral Analysis Section that there are three reasons for the series of poisoning cases. First, politics or religion; second, serial killers; Third, retaliation. ”

"I don't think political or religious reasons can be considered, because such reasons would generally cause mass casualties in a collective setting, and they would not be as long as this case, and the people who were poisoned would be so messy."

"I don't think serial killers can be considered, in most cases, serial killers will not commit crimes in a short period of time, which is not in line with the behavior habits of serial killers."

"So, I think there is only one reason for this poisoning case - revenge."

As soon as Wang Lei's words fell, Xia Xia, the criminal police captain of the Lingnan City Public Security Bureau, spoke, and his tone was full of dissatisfaction and depression: "You are Wang Lei's Wang Detective, we have heard of your reputation." However, I don't agree with your opinion. We had thought about it at first, but revenge should have a stated goal. There could be no one person who has hatred for so many people of all professions, all classes, and all ages, right? ”

Zhang Jian and several bureau leaders also nodded in agreement with Summer's statement, not to mention Summer's colleagues, all of whom were talking against Wang Lei. Han Hongfei's heart was extremely contemptuous, this is a detective, then everyone is a detective. The first consideration in the poisoning case is revenge, how can Lingnan not investigate, it seems that this Wang Lei is a young man after all, he is **, he is not firm, he dares to say this kind of thing casually, don't you know that you are looking down on the police in Lingnan when you say this? HeheheheWang Lei was not in a hurry or impatient, he looked like Jiang Taigong was fishing, until the people in Lingnan stopped the noise under Zhang Jian's forced gaze, and then continued: "I only said that the murderer's motive was revenge, not that the murderer was to take revenge on these eleven people. Zhang Jian's heart moved, and he asked: "Xiao Wang, please don't mind, they don't mean anything else, let's discuss with each other." So what do you mean? ”

"Paul? Professor Ekman also said that if the serial poisoning case is motivated by revenge, then the murderer will usually do a rehearsal before the revenge to get a clear idea of the drug's effect. So, I mean to say that these eleven people are not the targets of the murderer's revenge, they are just the objects of the murderer's rehearsal and the results! ”

The Lingnan City Public Security Bureau, headed by Zhang Jian, including Han Hongfei, was shocked by the information revealed in Wang Lei's words. Nine dead and two injured, such a big case is just the result of the murderer's test of poisoning, so when the murderer really takes protective action, I don't know how many people will die? Zhang Jian shivered, there was an active volcano sitting under his buttocks! I can't tell if it suddenly broke out that day, and I'm afraid I can only roll up and leave.

Mao Qiang and a few people think it's normal, and they need to be recruited by the national security to come over and participate in the case, to put it mildly, the case is not small, and the number of dead people must be at least ten figures. Do you think that Guoan has nothing to do all day long, and he came to help your local public security bureau investigate the case, hehe, you Lingnan know how to do it now, right? I know that we are awesome at the sea! Thinking of this, Mao Qiang's heart was filled with pride. He winked at Wang Lei, this is the way they often communicate in crowded situations, and the meaning is very simple: Is there a direction or clue? Wang Lei smiled and nodded unnoticed.

Zhang Jian glared at the group of people in his bureau, and now he knows that the Taoist people are reasonable, and they are still chirping crookedly just now! He said to Mao Qiang sincerely: "Captain Mao, on behalf of all the public security officers and police officers in Lingnan, I would like to express my gratitude to you, and thank you for your help." After the case is solved, I will accompany you not to get drunk and not return. So, where should we start now? ”
