After 42 years in prison and over one hundred murders, Brazil’s greatest serial killer and biggest murderer in the country’s prison system is now a free man.

Pedro Rodrigues Filho, or “Killer Pete,” was responsible for over 71 murders in and out of prison and was officially sentenced to over 400 years in prison. He was eventually released in 2018.

Born in Minas Gerais, the now 67-year-old was not a typical killer. Filho actively bragged about killing way more than he was imprisoned for and his tattoo-covered body contains symbols of his killings, with one across his arm with the words “I kill for pleasure.” According to him, he only kills those who are “no good,” including gang leaders, rapists and other criminals.

“[People are scared of me because] they never seek to understand why I kill. You see, I never killed children. I love children…. I also never killed women or fathers of good families,” Filho told Época magazine in 2003.

Filho, who was born with a fractured skull from his father beating up his mother while she was pregnant, committed his first murder at age 14. According to the media outlet O Globo, Filho killed the second to the Mayor for getting his father fired for false allegations that he stole food. He then killed the security guard who was allegedly responsible for the crime.

Since then, Filho has committed hundreds of murders by stabbing his victims, of which 47 murders were committed inside the prison he was detained at.

He also killed his father for the murder of his mother. In an interview with the Cometa Podcast in May, Filho said he stabbed his father, opened up his chest and ate a piece of his heart.

However, a prison psychiatrist that evaluated Filho said his father was killed by one of his lovers’ families, O Globo reported. It is uncertain which one is the true story.

“I can’t kill you for free. Why would I kill you if you have never done me or other people wrong,” Filho told the podcast host. “For me to kill someone it has to have been something serious.”

Filho was first detained in 1973 at age 19 and was released in 2007. After three years free, he was detained once again and finally released in 2018.

According to a 1982 forensic report made by two prison psychiatrists, Killer Pete was diagnosed with paranoid and anti-social behavior.

“God has forgiven me for my killings. Now I can’t kill anymore,” Filho said in May.
