Hu Chuguang's identity is the leader of the seventh group of serious cases in Anjing City! Because of the particularity of the Seventh Group of Serious Cases, the Seventh Group has always had its own secret office location. Zhuo Lefeng had previously intervened in seven groups of investigations because of a case, so he knew the office location of seven groups. But this time, Hu Chuguang brought Zhuo Lefeng to a new office location.

After coming here, Zhuo Lefeng found that it was well-equipped and the environment was good. But the only question is, what about the other team members?

Without waiting for Zhuo Lefeng to speak, Hu Chuguang first explained the problem: "The city bureau just held a meeting and decided that all the members of the seven groups would be disbanded, and then I would personally select every person who entered the group. You're the first new member I've picked! So from now on, you should call me Team Hu! ”

"All hands are disbanded!" Zhuo Lefeng opened his mouth in surprise, "Teacher Hu...... Ah, not Team Hu. Something can't have happened to Group Seven, right? ”

"I'll explain to you when it's time to explain, but now you only have one mission!" Hu Chuguang gestured to the side, and he had already placed the materials of Cheng Jianren and his other two cases on the table.

There are several clue characters written on the whiteboard in front of you, and there are several computers next to them. Being ready means getting started! Hu Chuguang is not a person who likes to rub off!

Although he saw something unusual, Zhuo Lefeng knew that Hu Chuguang had a tight mouth. What Team Hu doesn't want to say, no one can easily try it out! So, let's get straight to the point!

As Zhuo Lefeng guessed, this is indeed a serial murder case! Cheng Jianren was actually the third victim, and two more people died in the same way before that!

The body of the deceased, Lu Yongxiang, was found in Baidang Lake on the afternoon of March 11, and the forensic doctor determined that the time of death was between 2 a.m. and 5 a.m. on March 11. The body of the deceased, Xiong Zhao'an, was found in Matthew Hill on the morning of March 14, and the medical examiner determined that the time of death was between 1 and 4 a.m. on March 14. All three deceased were face stabbed prisoners, with multiple punctures on their bodies and no mutilated organs.

After reading the information, Zhuo Lefeng said: "Cheng Jianren is not only the person in charge of the accounting company, the company itself has a background in the underworld. It is written on the information that the behind-the-scenes boss of the accounting company is called Yu Youtai, known as Brother Tai, and many people in Anjing City know Brother Tai. Cheng Jianren is Yu Youtai's horse boy, to be precise, Cheng Jianren is a gangster. And Lu Yongxiang is a taxi driver. Xiong Zhaoan is a doctor. These three are not related from a professional point of view. There isn't much intersection between the network either! So, what kind of acquaintance should be able to know these three people at the same time, and be sure to do this to these three people? ”

Hu added: "It has been confirmed that the three victims did not know each other. In addition, the cause of death of the three victims was a puncture in the heart. The physical evidence department and the medical examiner did not find any biological residue of the killer on the deceased. ”

"The victim also had no skin tissue from the murderer's fingernails?" Zhuo Lefeng said to himself, "That means that there was very little physical contact between the deceased and the murderer, and there was no fight at all. The deceased barely had time to struggle. How exactly did this murderer do this? What kind of person would it be to be able to know all three of them at the same time, and still have the three of them absolutely trust the defenseless? ”

Hu Chuguang said: "If we knew what kind of person it was, we wouldn't have a headache here." ”

Zhuo Lefeng said: "In the crimes committed by acquaintances, most of the acts of doubling the torture of the victim are out of revenge. And how is it possible for a retaliator to reach out to the victim without causing the victim to be on guard? ”

"So what do you mean? The murderer is not enough to provoke the victim's defense? ”

Zhuo Lefeng nodded: "There are three types of people: physical defects, female gender, and people of old and young age will generally be considered to be inaggressive. In general, ordinary people have a weakened sense of defense when facing these three types of personnel. If the murderer really belongs to these three categories, then his motive for committing the crime is strange. Acquaintances commit serial crimes? And leave the victim defenseless! Also, judging from the modus operandi and process, the murderer is a well-planned killer. Acquaintance means directionality! An almost fixed time and manner of killing means planning! Directional and planned! So, could it be a carnival crime killer? ”

Hu Chuguang stared at him and thought, "Carnival crime murderer? Spree killers usually go through two stages. The first stage is directional, where the killer will stay in a specific geographical area or comfort zone to commit the crime until he feels that his criminal purpose has been achieved, and finally he will complete this stage of the crime at a destination that he thinks he has in mind. Then he will move on to the second stage of crime, which is random crime. At this stage, the killer appears to have no plan, and he will kill more often. That's when he was completely out of control. At this stage, the killer seems to be very planned, so do you think this killer is still in the first stage of binge crime? ”

Zhuo Lefeng nodded, got up and came to the whiteboard, he picked up the pen in his hand and marked the key information of the three victims: "Cheng Jianren's place of death is Fengxi Valley Scenic Area, Xiong Zhao'an's place of death is Matthew Mountain, and Lu Yongxiang's place of death is Baidang Lake." All three locations are scenic spots. If we assume that the killer's psychological comfort zone is some scenic spots, then it is consistent with the behavior of the binge killer who will commit crimes in a specific geographical area in the first stage. ”

At this point, Zhuo Lefeng can actually make an induction for the killer.

First of all, the killer and the three victims should all know each other, and it is very likely that they are women, or old and young, or have some kind of physical disability.

Second, the killer may be a binge murderer and is still in the first stage of binge homicide, that is, the stage of well-planned and targeted killing. The killer will kill people in his psychological comfort zone, and his psychological comfort zone is some scenic spots. This stage lasts until the killer feels that his goal has been achieved, and then completes the crime at his desired end, and then enters the second stage of random and unplanned killings.

In the end, the killer killed three people in a row, and also tattooed a prisoner on the faces of all three people, and also cut the victims' bodies. This must be a way of expressing demands. At this stage, the killer must have wanted to show his special relationship with the three victims. This prison word and the puncture of the body are important information, and the meaning needs to be clarified.

"The killer had a meticulous and complete criminal plan in the first phase. A well-thought-out crime plan generally includes a precise time and place of the crime. The killer chose the location of the crime in the scenic area, and the time of the crime ...... Hey, Team Hu, don't you think it's strange? The interval between the deaths of Lu Yongxiang and Xiong Zhaoan was three days, while the interval between the deaths of Xiong Zhaoan and Cheng Jianren became four days! It's one more day! ”

Hu Chuguang understood what Zhuo Lefeng meant, and he even showed a smile of appreciation: "You want to say that in the criminal mind, killers who are generally in the period of frequent crimes, the time interval between serial cases may be fixed, but more often the interval is reduced." But here the time interval increases! ”

Zhuo Lefeng said: "Yes, in the criminal mind, serial murderers rarely appear to have an increase in the time interval between crimes during the frequent crime period. Unless he had already selected the victim Cheng Jianren in advance before committing the crime, and the selected Cheng Jianren did not give the murderer a chance on the 17th or even the 16th, so the murderer was forced to do it on the 18th. But if the victim is selected in advance, and the murderer is a very clear planned crime, then he has already arranged how to lure the victim into the trap. Under such careful advance arrangements by the murderer, how did the victim Cheng Jianren escape the two days of the 17th or the 16th? Team Hu, I think it is very necessary for us to understand what Cheng Jianren has been doing in the past three days from the 15th to the 17th. ”

Zhuo Lefeng assumed that the killer would kill an acquaintance at the scenic spot every three days, so there must have been some accident here when Cheng Jianren arrived, so the killer killed Cheng Jianren on the fourth day. The killer is very confident and thoughtful, so who can stop him from killing Cheng Jianren on the third day?

"According to the information learned, Cheng Jianren is preparing a company etiquette event between the 15th and 17th, so he has been in contact with a model etiquette company." Hu Chuguang said, and glanced at it playfully!

This look definitely couldn't escape Zhuo Lefeng, and he hurriedly said, "Hey, hey, Hu." Your eyes are kind of teasing! Just tell me what you know! ”

Taking a deep breath, Hu Chuguang pursed his lips: "Listen, the model etiquette company that Cheng Jianren found is called Yanxin Etiquette." It's a company that's just been founded. I've looked at the profile of this company. The company was founded by two partners, one man and one woman. You must be familiar with the male partner. ”

"I know? Who is it? ”

"Jiang Junyan! Your college classmates. ”

Zhuo Lefeng, who was still smiling just now, instantly froze, his hand shook twice unconsciously, his eyes narrowed, and even his lips trembled slightly. The appearance of this name is like a pebble thrown into the lake, not just ripples but waves! Before, Zhuo Lefeng still had a relaxed mentality, but now, his expression was grim, and he didn't dare to slack off at all. He knew who he was going to face next. He also knew that he didn't have much affection for Jiang Junyan!

"He's troublesome and not easy to deal with. If it had anything to do with him, we'd have to do a lot of work. ”

Hu Chuguang sighed: "When I taught you back then, the two people in the class who impressed me the most were you and Jiang Junyan. I can see that you want to follow the right path in your heart, but Jiang Junyan is different, he has too many side ways. ”

"Even if he was my college classmate, if he really committed a crime, I would definitely arrest him with my own hands." After Zhuo Lefeng put the information on the table, he clenched his fists and said, "What's more, my relationship with him back then was not very good, and I didn't have much friendship with him." ”

Zhuo Lefeng and Jiang Junyan don't have much friendship? That's true! Throughout the four years of college, the two did not communicate much individually. Some of them don't look at each other. Moreover, there is indeed a great feud between them.
