Pedro Rodrigues Filho

Pedro Rodrigues Filho (29 October 1954 – 5 March 2023), also known as Pedrinho Matador, Killer Lil' Pedro, Killer Killer Petey, or simply Killer Petey, was a Brazilian serial killer, spree killer, vigilante, and YouTuber known for pursuing and killing other criminals and suspected criminals. He committed most of his crimes as a teenager, between the age of 14 and 19, and was officially sentenced for 71 murders, but claimed to have killed over 100 people, including drug dealers, rapists, and murderers, and served a total of 34 years in prison before his release in 2007. In 2011, Rodrigues was imprisoned again on charges of inciting riot and deprivation of liberty for crimes committed in prison; he was sentenced to eight years in prison, but was released again in 2018 after seven years on good behavior.

Following Rodrigues' initial planned 2003 release, author Jeff Lindsay began publishing a novel series about a fictional American serial killer of killers, inspired by Rodrigues, named Dexter Morgan. The series' success, along with that of its 2006 television adaptation and 2021 revival, led to widespread retrospective media attention being brought to Rodrigues, with him becoming internationally known alternately both as the "Brazilian Dexter" and the "South American Punisher" (after the Marvel Comics character of the same name).

After his second release from prison in 2018, Rodrigues declared himself to be reformed from his self-declared vigilantism as a youth and publicly vowed to commit no further crimes, becoming a Brazilian celebrity and YouTuber, maintaining a YouTube channel called "Pedrinho EX Matador" ("Ex-Killer Petey") on which he commented on modern crimes while educating the public that criminal acts are not something of which to be proud. In 2023, Rodrigues was killed in a drive-by shooting and stabbing by unidentified assailants.
