Join us as we delve into the life of Pedro Rodrigues Filho, the real-life 'Dexter' serial killer.

Early Life and the Birth of a Killer

Pedro Rodrigues Filho was born on a farm in Santa Rita do Sapucaí, a small town in Brazil. His birth was far from ordinary. His mother's attempted abortion with a knitting needle caused Filho to be born with a damaged skull.


This early trauma has been speculated to contribute to his later violent behavior. However, the influence of his upbringing cannot be overlooked. Filho's father was a known violent man, setting a disturbing example for his son.

Filho's first brush with violence came at a tender age. At just 13, he pushed his cousin into a sugar cane press, nearly killing him. This incident was a grim foreshadowing of the path Filho would take.

The following year, Filho committed his first murder. The victim was the vice-Mayor of Alfenas, who had recently fired Filho's father. This act of revenge marked the beginning of Filho's life as a killer.

His second murder followed shortly after. This time, the victim was a guard whom Filho believed was the real killer of his father's employer. With two murders under his belt, Filho fled to Mogi das Cruzes, a city in São Paulo state.

In Mogi das Cruzes, Filho's killing spree continued. He targeted drug dealers and gang members, carving out a reputation as a vigilante. His victims were often those he deemed as wrongdoers, a pattern that would persist throughout his criminal career.

Filho's early life was marked by a series of violent acts:

  • Attempted murder of his cousin at age 13

  • Murder of the vice-Mayor of Alfenas at age 14

  • Murder of a guard suspected of killing his father's employer

  • Multiple murders of drug dealers and gang members in Mogi das Cruzes

This period of Filho's life set the stage for his future crimes. His early exposure to violence, combined with his own violent tendencies, created a lethal mix. The birth of a killer was complete.

The Crimes of Pedro Rodrigues Filho

Pedro Rodrigues Filho's criminal career spanned several decades. His victims were diverse, ranging from criminals to innocent bystanders. His violent acts earned him the nickname "Pedrinho Matador" or "Killer Petey" in Brazil.


Filho's killing spree was not limited to the streets of Mogi das Cruzes. He continued his violent acts even after being arrested and imprisoned. His targets inside the prison were often other inmates, particularly those convicted of heinous crimes.

One of his most notorious prison murders was that of his own father. Filho's father was serving time for the murder of Filho's mother. In a chilling act of revenge, Filho killed his father and cut out a piece of his heart, which he then chewed.

Despite the gruesome nature of his crimes, Filho often portrayed himself as a vigilante. He claimed to target only those who deserved punishment, drawing parallels to the fictional character Dexter. However, his victims were not always criminals.

Filho's crimes were not limited to murder. He was also involved in several robberies and was known to be a part of a criminal gang. His criminal activities extended beyond Brazil, with reports of his involvement in crimes in Paraguay.

Filho's crimes were characterized by a certain brutality. He often used knives and guns to kill his victims, showing no mercy. His violent acts were often accompanied by a chilling calmness, a trait often associated with psychopaths.

Filho's crimes were not confined to a specific region or group of people. He killed in different cities and targeted a wide range of victims. This unpredictability made it difficult for law enforcement to track and apprehend him.

Despite his violent nature, Filho was not always the aggressor. He was known to have been attacked by other criminals, surviving multiple assassination attempts. His survival further cemented his reputation as a formidable criminal.

Filho's crimes were not without consequence. He was arrested multiple times and served several prison sentences. However, his time in prison did not deter him from committing further crimes. In fact, it seemed to fuel his violent tendencies.

Filho's crimes included:

  • Multiple murders of criminals and non-criminals

  • Murder of his own father in prison

  • Several robberies

  • Involvement in a criminal gang

  • Crimes committed in Brazil and Paraguay

Despite the severity of his crimes, Filho was often viewed with a certain fascination by the public. His story was sensationalized in the media, contributing to his notoriety. This public fascination with Filho and his crimes raises questions about the nature of crime and punishment in society.

Filho's crimes were not just acts of violence. They were a reflection of his disturbed psyche and a manifestation of his violent tendencies. His story serves as a stark reminder of the dark side of human nature.

Filho's crimes were not isolated incidents. They were part of a larger pattern of violence and criminal behavior. Understanding this pattern is crucial in understanding Filho and the factors that drove him to commit such heinous acts.

Filho's crimes were not the end of his story. His life took several unexpected turns, including a stint as a YouTube personality. His story continues to captivate and horrify, serving as a grim testament to the complexities of human nature.

Despite the severity of his crimes, Filho was not immediately sentenced to life in prison. The Brazilian justice system caps the maximum prison time at 30 years. This meant that despite being sentenced to 128 years in prison, Filho could only serve a maximum of 30 years.

Filho's interactions with the justice system did not end with his trial. He was in and out of prison multiple times, reflecting the challenges in managing repeat offenders. His repeated arrests and releases highlighted the limitations of the Brazilian penal system.

In conclusion, Filho's life behind bars was a testament to his resilience and adaptability. Despite the harsh conditions and constant threats, he managed to survive and even assert his dominance.

The Psychology of a Vigilante Serial Killer

Understanding the psychology of Pedro Rodrigues Filho is a complex task. His actions and motivations are a blend of psychopathy, vigilantism, and a twisted sense of justice. His story provides a unique insight into the mind of a vigilante serial killer.


Filho's violent tendencies can be traced back to his childhood. His upbringing was marked by violence and abuse, which likely played a role in shaping his violent behavior. His early experiences provide a glimpse into the nature versus nurture debate in the context of criminal behavior.

Filho's actions were not just about punishment. They were also about power and control. He derived satisfaction from exerting power over his victims, reflecting a Machiavellian mindset. His actions provide an insight into the dark triad of personality traits - narcissism, Machiavellianism, and psychopathy.

Filho's actions were not just driven by his personal beliefs. They were also influenced by the societal norms and values of his time. His story provides a reflection of the societal attitudes towards crime and punishment in Brazil during his time.

Despite his violent actions, Filho was not an outcast. He had a following, both inside and outside the prison. His popularity reflects the public's fascination with vigilante justice and the allure of the anti-hero.

Pedro Rodrigues Filho vs. Dexter: Comparing Fiction with Reality

The comparison between Pedro Rodrigues Filho and the fictional character Dexter Morgan is intriguing. Both are serial killers, but their motivations and methods differ significantly. This section will explore these differences and similarities.


Dexter Morgan, the protagonist of the TV series 'Dexter', is a forensic blood spatter analyst for the Miami Metro Police Department. By day, he helps solve murders. By night, he commits them. Dexter's victims, like Filho's, are criminals who have escaped the justice system.

However, Dexter's killings are methodical and ritualistic, following a strict 'code' taught to him by his adoptive father. Filho, on the other hand, was more impulsive and less methodical in his killings. His actions were driven by personal vendettas and a sense of street justice.

Dexter's character is portrayed as a likable anti-hero. Despite his murderous tendencies, viewers find themselves rooting for him. Filho, in contrast, is a real-life killer. His actions have caused real harm and suffering, making it harder to view him as an anti-hero.

Dexter's character is also marked by a struggle with his 'dark passenger' - his urge to kill. He constantly battles with this part of himself, trying to balance his homicidal urges with his desire to lead a normal life. Filho, however, does not appear to have this internal conflict. He seemed to embrace his violent tendencies without remorse.

Despite these differences, both Dexter and Filho challenge our notions of justice. They operate outside the law, taking matters into their own hands when the justice system fails. Their stories force us to question the boundaries of right and wrong, and the lengths one might go to in the pursuit of justice.

In conclusion, while there are parallels between Pedro Rodrigues Filho and Dexter Morgan, they are fundamentally different. One is a fictional character whose actions are confined to the realm of television. The other is a real-life killer whose actions have had real and devastating consequences. The comparison, however, provides a fascinating exploration of the psychology of vigilante serial killers.

What is clear, however, is that the media's portrayal of Filho has significantly shaped public perception of him. For some, he is a ruthless killer to be feared. For others, he is a vigilante hero who took justice into his own hands.

Public Perception and the Fascination with True Crime

The public's perception of Pedro Rodrigues Filho is complex and multifaceted. For some, he is a ruthless killer to be feared. For others, he is a vigilante hero who took justice into his own hands.


This dichotomy is not unique to Filho. The public's fascination with true crime stories often involves a mix of fear, disgust, and a strange kind of admiration. This fascination can be seen in the popularity of true crime documentaries, podcasts, and books.

The case of Filho is particularly interesting because of his vigilante-style killings. He targeted criminals and wrongdoers, which has led some to view him as a hero. This perception is further fueled by Filho's own narrative, in which he portrays himself as a defender of justice.

However, it's important to remember that Filho is a convicted serial killer. His actions resulted in the deaths of dozens of people. Regardless of his victims' criminal backgrounds, Filho's actions were violent and illegal.

Legal and Ethical Implications of Vigilante Justice

Pedro Rodrigues Filho's story raises many legal and ethical questions. His vigilante-style killings blur the lines between justice and crime, making it a complex case to dissect.


From a legal perspective, Filho's actions are clearly criminal. He took the law into his own hands, deciding who deserved to live or die based on his own moral code. This is a clear violation of the law, which is designed to ensure that justice is served through a fair and impartial process.

However, the ethical implications of Filho's actions are more complex. Some argue that he was serving a form of justice by targeting criminals who had evaded the law. This perspective views Filho as a vigilante hero, delivering justice where the legal system had failed.

Yet, this viewpoint raises its own ethical dilemmas. Is it right for an individual to take justice into their own hands? Does the end justify the means? And who gets to decide what is just and what is not?

These questions highlight the ethical complexities of vigilante justice. While it may seem appealing in theory, in practice it often leads to violence, chaos, and a disregard for the rule of law.

In the case of Pedro Rodrigues Filho, his actions have had far-reaching implications. They have sparked debates about justice, ethics, and the role of the individual in enforcing the law. These debates continue to this day, making Filho's story a fascinating case study in the legal and ethical implications of vigilante justice.

Rehabilitation and the Brazilian Penal System

The case of Pedro Rodrigues Filho also brings into focus the Brazilian penal system and its approach to rehabilitation. Filho's life in and out of prison raises questions about the effectiveness of the system in rehabilitating criminals.

Brazil's prisons are known for their harsh conditions. Overcrowding, violence, and lack of basic amenities are common. These conditions can make rehabilitation a challenging task. In Filho's case, his time in prison seemed to have little effect on curbing his violent tendencies.

In fact, Filho committed a significant number of his murders while incarcerated. This suggests that the prison environment may have exacerbated his violent behavior rather than curbing it. It raises questions about the effectiveness of the Brazilian penal system in rehabilitating violent criminals.

The Brazilian penal system caps the maximum prison time at 30 years. This means that even individuals convicted of multiple murders, like Filho, can be released. This policy is based on the belief in the possibility of rehabilitation. However, Filho's case challenges this belief.

After his release in 2007, Filho was re-arrested for riot and false imprisonment. This suggests that his time in prison did not rehabilitate him. Instead, it seems to have reinforced his criminal behavior.

The case of Pedro Rodrigues Filho highlights the challenges faced by the Brazilian penal system. It raises important questions about the balance between punishment and rehabilitation, and the ability of the system to reform violent criminals.

In the end, the story of Pedro Rodrigues Filho serves as a stark reminder of the complexities of the penal system and the challenges of rehabilitation. It underscores the need for a comprehensive approach that goes beyond punishment to address the root causes of criminal behavior.

The Aftermath: Release and Re-arrest

Pedro Rodrigues Filho's release from prison in 2007 was met with mixed reactions. Some saw it as a failure of the Brazilian penal system, while others viewed it as a testament to the belief in rehabilitation.


However, Filho's freedom was short-lived. In 2011, he was re-arrested on charges of riot and false imprisonment. This re-arrest raised questions about the effectiveness of the Brazilian penal system in rehabilitating violent criminals.

Filho's re-arrest also highlighted the challenges faced by ex-convicts in reintegrating into society. Despite his notoriety, Filho struggled to find employment and faced social ostracism. This raises questions about the support systems in place for ex-convicts in Brazil.

The story of Pedro Rodrigues Filho serves as a stark reminder of the complexities of the criminal justice system. It underscores the need for a comprehensive approach to rehabilitation that goes beyond punishment.

In the end, the story of Pedro Rodrigues Filho is a testament to the enduring impact of crime on individuals and society. It serves as a reminder of the challenges faced by the criminal justice system in dealing with violent criminals.

In the end, the legacy of Pedro Rodrigues Filho is a complex one. It is a story of violence and retribution, of justice and punishment, and of the thin line that separates a hero from a villain.
