The family of three who were killed this time had no contact with the six people who were killed before, which made the police investigation confused for a while.

But soon the police discovered the connection between the two families whose children were in the same class at the same school.

This major discovery also led the police to shift the focus of their investigation to the school, to the teachers at the school, and to classmates or parents in the classes of the two children who were killed.

On the one hand, the police need to confirm whether there are conflicts between the school teacher and the parents who were killed, and at the same time, they also need to investigate some possible conflicts among the students in the class, such as whether the victim student bullied which student at school, or which student was bullied.

The investigation soon progressed. There was no suspicion on the part of the teachers, but the police found a breakthrough among the students.

There is a very special student in the class, his name is Chen Zhongliang, a child with cerebral palsy. Fortunately, Chen Zhongliang's intelligence was not affected too much, and his grades were always in the upper middle of the class, but his legs could barely bend, it was very difficult to walk, he had to rely on crutches, and he often had incontinence, because of this, he was often ridiculed and bullied by his students, and the two children who bullied him most often were killed.

The police then identified Chen's parents as suspects. Except for the fact that Chen Zhongliang was bullied at school, since the first murder case, Chen Zhongliang has not been back to school, and no one has come to the school to say hello, the school has been to his house, but there is no one in the family, which obviously shows that Chen Zhongliang's family has absconded in fear of crime.

After understanding, Chen Zhongliang is a single parent, and he lives with his father. Chen Zhongliang's father's name is Chen Mu, and he works at the History Museum, and in order to treat his children, Chen Mu seems to be doing other part-time jobs, and Chen Mu has not been to work in the museum for a long time recently.

Doing multiple jobs, the child is still cerebral palsy, as a single father, Chen Mu's pressure can be imagined, under the heavy pressure brought by life, Chen Mu is likely to make some excessive excitement.

The police soon found Chen Mu's home, but no matter how the police knocked on the door, no one answered, and there was a faint smell of odor coming from the door. The police questioned the neighbors, who replied that they had not seen Chen Mu and Chen Zhongliang, father and son, for several days.

The police immediately decided to break down the door and enter the house, and the moment they slammed the door open, a pungent stench came out of the room - two headless corpses were waiting for the police in the house.

Both of the deceased were males, one of whom was an adult male who was in very strong health, and the other was a child with obvious muscle atrophy in both legs due to lack of exercise. Although the police were unable to find the deceased's head in the end, the identity of the deceased can be determined by the condition of the body.

Later, according to the forensic examination, the time of death of the two deceased was nine days ago, which means that the father and son were dead before the first case of killing a family of six. Strictly speaking, this is the first case of extermination.

The suspect who had just been found turned into the original victim in an instant, and such a turn of events also made the police feel confused.

Eleven people were killed in a row, and all of them were beheaded, but all but the first father and son had their heads found.

Where did the heads of the father and son go?

Some believe that the murderer took the head, but his purpose is unknown; Some people also believe that the murderer is the father and son, and the headless corpse may just be used by the murderer to distract his vision. In either case, the police could only investigate the class of the three murdered children, and arrange for the police to patrol the students' homes in plainclothes while waiting for the suspects to show up.

In the following month, there was no beheading, and just when the police suspected that the murderer had fled to other provinces, another beheading occurred! The murder was carried out by five construction workers who had been beheaded in a rest shed at the construction site, which took place at 9 p.m. and where empty wine bottles were found. Police determined that five workers had been beheaded while drunk.

The five men had no connection to the three slain children, to the school, and to none of the students' parents.

Two weeks later, the police received another report that four men had been hacked to death on the mahjong table in a private house, and the same heads had been cut off, but all the money on the mahjong table was gone, apparently another vendetta.

Two consecutive unconnected murders completely distracted the police from the investigation. While the police began to hesitate whether it was necessary to guard the students' homes, a murder related to the school finally occurred, and the head teacher of the class of the three murdered students was killed, and the deceased was also beheaded.

In less than two months, 23 people across the city have been beheaded, especially the schools where the three students were killed have been completely panicked.

Three weeks later, the beheading case occurred again, this time not in the city, but in the countryside of another county. The victims were a family of seven, including two elderly people and five sisters. This is another case of murder, and the deceased was also beheaded.

This time, after confirming the identity of the victim, the police finally found the connection point, and the eldest daughter of the five sisters who was killed was the mother of Chen Zhongliang, a child with cerebral palsy in the first case of beheading, that is, Chen Mu's ex-wife. According to the subsequent investigation, the mother divorced Chen Mu when the child was six years old, and then returned to the countryside to live until now.

This discovery led the police to target Chen Mu again, because his head has not been found yet.

And the day after the police left the village, another family in the same village also had a murder case, and the family of five died, and the way of death was still decapitated. According to the clues provided by the villagers, the two families who were wiped out have been very close recently, and it seems that they are preparing to get married, and the two people who got married are the eldest son and eldest daughter of the two families.

This connection convinced the police that the headless father and son who died in the first place were definitely stand-ins, and that Chen Mu might now be waiting for an opportunity to retaliate against others.

In less than half a day, the police determined that this judgment was correct, and they took Chen Mu's photos to the construction site where five workers were killed. Someone on the site recognized Chen Mu and they determined that Chen Mu had worked as a temporary worker on the construction site for a period of time, about two weeks before the five workers were killed.

It is absolutely impossible for Chen Mu to go to the construction site to work as a temporary worker a month after his death, and the murderer must be Chen Mu.

The police immediately issued a wanted warrant for the whole province to arrest Chen Mu, and on the third day after the wanted warrant was issued, the police received a report that someone in the history museum where Chen Mu worked before saw someone very similar to Chen Mu.

The police quickly rushed to the historical museum, and almost at the same time as the police arrived, a man who was covered in blood and bruises also ran from the direction of the museum warehouse. The man ran to the police as if he had lost his soul and shouted, "Cut someone!" There are madmen who cut people! ”。

The madman he was talking about was naturally Chen Mu, who was condemned to have died at home two months ago.

A large number of police officers immediately rushed to the museum warehouse and blocked Chen Mu in the warehouse. Chen Mu was holding an ancient battle axe from the museum's collection in his hand, and at the same time, he had tied up three drenched people as hostages, and the whole warehouse was filled with a strong smell of gasoline.

The police did not dare to shoot lightly, because a small spark could cause the entire warehouse to catch fire or even explode. But Chen Mu did not have any confrontation with the police at all, he struck a match and threw it on the three kidnapped people, and in an instant a fire engulfed the entire warehouse.

The police had no choice but to surround the warehouse on the perimeter. When the fire was finally extinguished, the police found only three charred headless corpses in the warehouse, and Chen Mu seemed to have disappeared right under the eyes of the police, leaving only a bloody ancient double-edged battle axe on the ground.
