"In the first album project, six unfinished cases were added to the fact that one murderer was incapable of conduct. There were seven "unsuccessful" cases in total, and the biggest suspect died suddenly. The seventh case, that is, the murder of Zhu Feng's husband Yu Bin, was a bit special." Luo Wenzhou took an old file handed over by Xiao Haiyang, opened it on the coffee table, and showed it to everyone. He and Fei Du were only alone in that short section on the road. The home had long become a stronghold outside the municipal bureau, with cigarette butts and cans and cans and bottles of cans that had only half left.

Luo Wenzhou: "Zhu Feng insisted that the man who was locked in a mental hospital was defeated because his physical characteristics did not match the murderer she ran into at the crime scene."

"The murderer who killed people in the street is named 'Qian Cheng'. He lives near the crime site. The neighbors and neighbors around him know him. Because of mental disorders, Qian Cheng does not have the ability to live independently. He still lives with his old father in his forties. After his father passed away, he entrusted him to a relative. The relative collected money, but he was not careful. He only went to see him once a week and let him wander around and eat garbage when he was hungry. However, even though crazy, the neighbors said that he did not provoke others, his temper was relatively gentle and not very aggressive. At first, he heard that he killed someone, but no one could believe it - the person in the photo was the murderer Qian Cheng."

Xiao Haiyang reached out and clicked on the photos in the old file. One was the photo when he was just caught. The man and his clothes were ragged and black, and there was no one at all. He looked like a walking mop; the second photo was much more refreshing, he had already cleaned up, shaved his head, and changed into prison uniforms. This time he could see his original appearance. He seemed to be a middle-aged man with a flat head and a straight face, but his eyes and expression were a bit strange, and he didn't look like a sober normal person.

"People with mental disorders in judicial appraisal have strict procedures for incapacitated people. Even more than ten years ago, the management of this area was not so perfect, and fraud was not as easy as outsiders imagined. Moreover, if someone disagrees with the appraisal conclusion, they can apply for another opinion in court to be issued by another institution." Luo Wenzhou said, "This murderer is famous and has a surname in the local area. Everyone around him knows him and knows that he is sick. It is unlikely that it is fake."

"And this man is a mentally ill person who eats garbage. He has no money or background and doesn't even care about relatives. To put it bluntly, he is just a burden," said another detective. "Who would take such a big risk for him to commit fraud? I don't think Zhu Feng is trustworthy."

Fei Du swept through the case description in the file in a glance—

The murderer escaped after committing the crime... He quickly sent a police officer... with the help of enthusiastic people... blocked the alley... The weapon... blood stains...

He raised his eyebrows and suddenly looked at the two photos that Xiao Haiyang had just taken out.

"It's right. My relatives treat him as a burden. They are usually not upset. They wish that he would disappear and would not return to anyone to look for him if he lost it." Fei Du whispered, "Is there a map near the crime site at that time?"

"Yes!" Xiao Haiyang was very careful in his work. He immediately took out an old map marked with densely marked.

"The crime was on a spontaneously formed street of small vendors. I sorted out the witness testimony. At that time, the deceased Yu Bin must have had an argument with the murderer in front of a meat stall at the intersection. Then the conflict escalated. The murderer suddenly picked up the knife from the meat stall, stabbed the dead man to death, and then fled to the road opposite the intersection. He also ran back to get the keys on the side of the road. After getting up, he continued to run with a bloody weapon and crossed the road. A few minutes later, the police and security guards arrived, and some brave masses guided the way to help search. About ten minutes - this was recorded in the witness testimony, and there may be errors - the police grabbed Qian Cheng in an alley."

Fei Du: "Where is the arrest site?"

Xiao Haiyang looked carefully and drew a circle on the map: "It should be this, across the road is a shanty town to be demolished."

Luo Wenzhou: "What, what's the problem?"

"I think there are two more reliable speculations," Fei Du said. "First, the murderer was impersonated was false, and Zhu Feng was talking nonsense himself..."

"Second, the murderer was indeed dropped, but not during the arrest and trial, but before he was arrested."

Luo Wenzhou was stunned, and then immediately reacted: "You mean, the murderer who killed someone in the street is not the same as Qian Cheng, who was caught by the police at the scene at that time?"

"When the murderer killed someone, and Qian Cheng was arrested, he was covered in dirt. He was dressed as a typical homeless man and his facial features were hard to distinguish. As long as his physical characteristics were similar, in that sudden situation, it was normal for those passers-by to see the difference unless they were familiar."

Xiao Haiyang: "Qian Cheng is a mentally disabled person who has no control over it, and I'm afraid he has no acquaintances."

Fei Du continued: "Apart from eyewitnesses, the decisive evidence was blood clothing and murder weapon. If, as Haiyang said, there was a certain time difference between the murderer's escape and the final arrest, it would be not difficult to do anything in it - he first needed to find a place to settle in the shanty town waiting to be demolished, kidnap Qian Cheng, and after killing people, he took advantage of the chaos to escape from the public's vision, escape into the shanty town, wiped his fingerprints, and stuffed the blood clothing and murder weapon to Qian Cheng."

"As soon as a homeless man wearing a bloody suit and holding a murder weapon appeared, if someone shouted "The murderer is there" at this time, the person who was chasing the murderer would immediately subconsciously chase him and think he had caught the murderer. Anyway, this madman couldn't even say anything, and he couldn't figure out what happened, let alone defend himself." Fei Du paused, "Wuhen kills people in public, as long as the retreat route is calculated properly, no accident, it is much more operational than buying the public security, procuratorial and judicial system."

Xiao Haiyang was so cold that he was talking about it.

"Qian Cheng's neighbors all said that although this person is abnormal, he has a gentle personality. Zhu Feng also confessed that Yu Bin is a person who doesn't like to have conflicts with others. Both of them seem to be fighting on the street for a little trivial matter," Fei Du whispered, "This is a deliberate murder."

"But... why should I kill an ordinary art teacher?"

"This question is very critical," Fei Du raised his eyes and looked at Luo Wenzhou, "Also, who was stabbed to death in a mental hospital later? Is it the real murderer? Or the unlucky scapegoat Qian Cheng?"

"It's Qian Cheng," said Xiao Haiyang, "Qian Cheng's basic information was registered when he was arrested. Of course, it was necessary to go through a forensic autopsy to confirm the identity of the body. The incident of the person being replaced in the middle must have been exposed. Moreover, Zhu Feng also said that the murderer who killed her husband was still at large. She did not admit that the real murderer who died in the mental hospital was the real murderer who killed Yu Bin - what does this mean?"

Fei Du: "If the above speculation is correct, Qian Cheng should not have been killed by the 'reciter' because he is innocent."

"Do you think the reciter does not kill innocent people?" Luo Wenzhou's expression was a little gloomy, "Then Chen Zhen, Feng Bin, and Xiao..."

"No," Fei Du interrupted him, "the reader will not use this kind of ritualistic technique to kill innocent people."

He said, stood up and walked to the balcony that was integrated with the living room. Scattered firecrackers sounded in the distance. This year, the city was not strictly managed, and many people set off firecrackers in advance, making the sky that had been bright for a few days shrouded in smoke again.

"I can probably give the reader a simple psychological portrait now."

Fei Du closed his eyes slightly. The man who appeared in Fei Chengyu's basement many years ago like a ghost showed a mysterious smile in the depths of his memory. He was tall and had deep eye sockets. He was filled with thick and indelible shadows in his eyes, and reflected an almost dazzling light... sharp, cold, and as if it was hatred.

"'Reciter' is a mutual aid organization composed of former victims. The trauma that is not properly relieved for a long time will hurt people's sense of trust. Sometimes it is accompanied by symptoms of excessive alertness and strong aggressiveness. It will change a person's personality, alienate himself, withdrawn, and increase the sense of estrangement from others in society. Only when facing people of the same experience can you develop a sense of belonging - this is the reason why the mutual aid organization is beneficial."

"But normal mutual aid organizations allow the traumatized to allow the traumatized to be in a relatively comfortable and sense of belonging environment, guided by professionals, relieve pressure from each other's positive feedback, accept the facts, slowly walk out of the small circle, and return to normal life, rather than immersing them in each other's negative feedback, aggravate the barriers from the outside world, and finally develop into a small group that is closed, isolated, and erases independent consciousness."

"There are many documents on the research on mass psychology. The famous Paris September tragedy and the Rwandan massacre are typical cases. The initiator of the 'Reader' is an expert in this field. He successfully built such a group - they believed that they were persecuted, just, and traumatic excessive alertness was constantly strengthened. The initial hatred for the perpetrators would be like a bowl of filled water, which overflowed and spread to everyone outside the world - the unfairness they felt was the fault of society, the fault of everyone in this society. As for the police who should have presided over justice, they were even more dereliction of duty and unforgivable."

"In the end, people outside the small group are objectified and can easily become tools of revenge. Even if innocent people hurt, they are regarded as necessary sacrifices on the road to revenge and justice," Fei Du's eyes swept to all the implicit anger. "But the 'revenge tool' and the 'object of revenge' are different. In order to increase the cohesion of the group, they must have a certain belief. Cultivating this belief requires a sense of ritual - for example, to the criminal "for tooth" and die from the crimes he committed."

"You mean, Fan Siyuan, the initiator of the reader, designed this group since he killed the first person in the first album plan." Luo Wenzhou asked, "Murder is part of his plan, not a 'gaze-looking' style of being obsessed with it."

"No," said Fei Du, "This group is stable in structure, streamlined members, strong cohesion, and very loyal. It was designed and cultivated by Fan Siyuan consciously. He was the first to be a 'voluntary policeman' and murder suspects who were not punished was not out of righteous indignation. If Fan Siyuan had contacted Zhu Feng earlier, he should have realized that the person locked in the mental hospital was not the real murderer, and killing him was meaningless."

"The time when Zhu Feng broke into the mental hospital was very close to the time when Qian Cheng was finally killed," Luo Wenzhou pondered for a moment and said, "Is it possible that this is the case? When the real murderer heard Zhu Feng's accusation, he realized that the matter of replacing people was not so seamless. It happened that something happened to happen to the album, so he took the case into troubled waters - giving people an unconscious impression that Qian Cheng was the target of revenge, so he was the real murderer. Later people would preconceive and would not pursue it carefully."

Xiao Haiyang suddenly jumped up: "So the murder case of Zhu Feng's husband Yu Bin was arranged by an insider of the municipal bureau back then!"

Luo Wenzhou: "Go to check where Yu Bin has been in contact with people, schools, students he taught during his lifetime."

Xiao Haiyang jumped up.

At this time, another criminal policeman asked: "Captain Luo, did the insider in the past have a suspect? Should we keep an eye on it?"

Before Luo Wenzhou could speak, Fei Du took a look at his watch.

"Not for now," said Fei Du, "the time is almost over, and someone will go."

After the investigator in charge of Fei Du sent the person away, the people couldn't stop going back and carefully looked at Fei Du's surveillance records. It took a long time and chatted with different people for several hours, and the information was complicated and disorderly. He first found something related to Pan Yunteng and went from beginning to end. As Fei Du said, it was all the students inexplicably inquired and greeted, and there was nothing valuable. The investigator was a little disappointed and was about to give up, but he vaguely felt that something was making him feel like a thorn in his throat.

When he combed the information from beginning to end again, he suddenly noticed something and pressed to pause playback.

On the screen, a subtle look flashed across Fei Du's face, and then he sent a voice message as if he was pretending to be calm: "I haven't heard of it, what can I do?"

The investigator was stunned for a moment, and then he replayed the conversation between Fei Du and the "philosopher" from beginning to end, and then called the technician - Fei Du did not plug in the headphones, and did not put the earpiece tightly on his ear when listening to the voice information. The male voice vaguely in the phone's earpiece could be heard directly in the eavesdropper. After amplifying it through technical means, the voice message sent by the "philosopher" was very clear.

The keyword "Zhang Ting" made the investigator shudder.
