Hu Chuguang's identity is the leader of the Seventh Group of the Serious Case in Anjing City! Because of the special nature of the Seventh Group handling cases, the Seventh Group has always had its own secret office location. Zhuo Lefeng had previously intervened in the Seventh Group's investigation because of a case, so he knew about the Seventh Group's office location. But this time Hu Chuguang brought Zhuo Lefeng to a new office location.

After coming here, Zhuo Lefeng found that the equipment was fully equipped and the environment was good. But the only problem was, what about the other team members?

Before Zhuo Lefeng could speak, Hu Chuguang explained this question first: "The Municipal Bureau had just held a meeting and decided to disband all the seventh group members. After that, I will personally choose each member of the group. You are the first new group member I selected! So from now on, you should call me Team Hu!"

"All members disbanded!" Zhuo Lefeng opened his mouth and was extremely surprised, "Teacher Hu... It's not Team Hu. Could something be wrong with Group 7?"

"I will explain it to you when it's time to explain it to you, but now you only have one task!" Hu Chuguang signaled to the side. He had already placed the information of Cheng Jianren and his other two cases on the table.

There are several clues and names of characters written on the whiteboard in front, and there are several computers next to it. It is ready, which means that the work will start immediately! Hu Chuguang is not a person who likes to be procrastinated!

Although he saw something strange, Zhuo Lefeng knew that Hu Chuguang was very strict. No one could easily test what Team Hu didn’t want to say! So, get straight to the point!

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

The body of the deceased Lu Yongxiang was found in Baidang Lake on the afternoon of March 11. The forensic doctor determined that the death time was between 2:00 and 5:00 on March 11. The body of the deceased Xiong Zhao'an was found in Matai Mountain on the morning of March 14. The forensic doctor determined that the death time was between 1:00 and 4:00 on March 14. The three deceased were all imprisoned on the face, and their bodies were pierced and cut into pieces and their organs were not damaged.

After reading the information, Zhuo Lefeng said: "Cheng Jianren is not only the person in charge of the company for accounting, but the company itself has a gangster background. The information says that the boss behind the company for accounting is Yu Youtai, known as Tai Ge. Many people in Anjing City know about Brother Tai. Cheng Jianren is Yu Youtai's mascot. To be precise, Cheng Jianren is a gangster in the world. Lu Yongxiang is a taxi driver. Xiong Zhaoan is a doctor. These three are not related from a professional perspective. There is not much intersection between personal connections and networks! So, what kind of acquaintance should be able to know these three people at the same time, and you must attack these three people?"

Hu Chuguang added: "It has been confirmed that the three victims do not know each other. Also, the cause of the death of the three victims is that the heart and mouth parts were pierced. The physical evidence department and the forensic doctor did not find any biological residues of the murderer on the deceased."

"The victim's nails do not have the murderer's skin tissue?" Zhuo Lefeng said to himself, "That means that there is very little physical contact between the deceased and the murderer, and there is no fight at all. The deceased almost didn't even have time to struggle and resist. How did this murderer do this? What kind of person would be who can know these three people at the same time and make the three people absolutely trust unprepared?"

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

Zhuo Lefeng said: "In the crime of acquaintances, the act of torture the victims twice as much as possible is mostly retaliation. How can a revenge person contact the victims without causing the victims' precaution?"

"So what you mean is that the murderer is not enough to get the victim's defense?"

Zhuo Lefeng nodded and said, "There are physical defects, female gender, and the elderly and young people, and these three types of people will be generally considered to be lacking in offensiveness. Generally speaking, ordinary people are weakened when facing these three types of people. If the murderer really belongs to these three types of people, then his motive for crime is strange. Acquaintances commit crimes in a series of crimes? And the victim is unprepared! Also, from the method and process of committing the crime, the murderer is a killer with meticulous plans. Acquaintances mean direction! Almost fixed killing time and method means planning! Directionality and planning! So, will it be a carnival criminal murderer?"

Hu Chuguang looked at him and thought, "Carnival Crime Killer? Carnival Killer usually goes through two stages. The first stage is directional. The killer will stay in a specific geographical area or comfort zone to commit crimes until he feels that his purpose of crime has been achieved and will eventually complete this stage of crime at a destination he thinks. Next, he will enter the second stage of crime, which is random crime. At the beginning of this stage, the killer looks unplanned and he will kill people more frequently. At that time, he completely loses control. At this stage, the killer looks very planned, so do you think the killer is still in the first stage of carnival crime?"

Zhuo Lefeng nodded, stood up and went to the whiteboard. He picked up the pen in his hand to mark the key information of the three victims: "Cheng Jianren's death is Fengxi Valley Scenic Area, Xiong Zhao'an's death is Matai Mountain, and Lu Yongxiang's death is Baidang Lake. These three locations are all scenic spots. If we determine that the killer's psychological comfort zone is some scenic spots, it is in line with the behavioral test of the carnival killer's crimes in a specific geographical area in the first stage."

At this point, Zhuo Lefeng can actually summarize the killer.

First of all, the killer and the three victims should be aware of them, and are most likely to be women, young or old, or people with some kind of physical disability.

Secondly, the killer may be a carnival murderer, and is still in the first stage of carnival murder, that is, a stage of careful planning and targeted murder. The killer will kill people in his psychological comfort area, while his psychological comfort area is some scenic spots. This stage will continue until the killer feels that his purpose has been achieved, so he will complete this stage of crime at his ideal end point, and then enter the second stage of random murder and unplanned murder.

In the end, the killer killed three people in a row, and even stabbed the word "prison" on the faces of three people, which also cut the victim's body. This must be a way to express his appeal. The killer must want to show his special relationship with the three victims while committing a crime at this stage. The word "prison" and the puncture of the body are important information, and it is necessary to figure out the meaning.

"The killer has a meticulous and complete crime plan in the first stage. A meticulous and complete crime plan generally includes an accurate crime time and crime location. The killer chooses the crime location in the scenic area, and the crime time... Hey, Team Hu, don't you find it strange? The death interval between Lu Yongxiang and Xiong Zhao'an is three days, while the death interval between Xiong Zhao'an and Cheng Jianren is four days! This is an extra day!"

Hu Chuguang understood Zhuo Lefeng's meaning, and he even showed a hint of appreciation: "You want to say that in the criminal psychology, killers who are usually in frequent crimes, the time interval for crimes in a series of cases may be fixed, but in more cases, the interval time is reduced. However, the time interval increases here!"

Zhuo Lefeng said: "Yes, in the criminal psychology, serial murderers rarely have the time intervals for crimes that increase in the crime period. Unless he had already chosen the victim Cheng Jianren in advance before committing the crime, and Cheng Jianren, who was selected, did not give the murderer a chance on the 17th or even the 16th, so the murderer was forced to take action on the 18th. However, if the victim was chosen in advance and the murderer was a very clear planned crime, then he had already made arrangements for how to lure the victim into the trap. With the murderer's careful arrangement, how did the victim Cheng Jianren escape from the 17th or the two days of the 16th? Team Hu, I think it is very necessary for us to understand what Cheng Jianren has been doing in the three days from the 15th to the 17th."

Zhuo Lefeng assumes that the killer will kill an acquaintance at the scenic spot every three days, so there must be some accident when he arrives at Cheng Jianren, which leads to the killer killing Cheng Jianren on the fourth day. The killer is very confident and has great ideas. So who can stop him from killing Cheng Jianren on the third day?

"According to the information we learned, Cheng Jianren was preparing for a company's etiquette activity between the 15th and 17th, so he has been in contact with a model etiquette company." Hu Chuguang said, and even took a sarcasm!

This look must not escape Zhuo Lefeng. He hurriedly said, "Hey, Team Hu. Your look is like teasing! Just say whatever you know!"

Taking a deep breath, Hu Chuguang pursed his lips: "Listen, the model etiquette company Cheng Jianren looked for is called Yanxin etiquette. This is a company that has just been established. I have read the information about this company. This company was established by two partners of a man and a woman. You must be familiar with that male partner."

"I know? Who?"

"Jiang Junyan! Your college classmate."

Zhuo Lefeng, who was smiling just now, instantly his expression frozen. His hands trembled unconsciously, squinted their eyes, and even his lips trembled slightly. The appearance of this name was like a stone thrown into the lake, not just ripples but waves! Zhuo Lefeng had a light attitude before, but now, his expression was grim and he did not dare to neglect at all. He knew who the opponent he was going to face next. He also knew that he did not have much affection for the three words Jiang Junyan!

"He is very troublesome and difficult to deal with. If this matter is related to him, we will have to go through a lot of trouble."

Hu Chuguang sighed: "When I taught you the class, the two people who left the deepest impression on me in the whole class were you and Jiang Junyan. I can see that you want to take the right path in your heart, but Jiang Junyan is different. He has too many side-by-siders."

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

Zhuo Lefeng and Jiang Junyan don’t have much friendship? This is true! The two of them did not communicate alone for four years in college. They were a little disliked. Moreover, there was indeed a big holiday between them.
