Pedro Rodrigues Filho also known as Pedrinho Matador is a Brazilian serial killer who killed innocent people and other criminals. He also became known as the Brazilian Dexter due to his similarities to the titular character from the television series Dexter. Filho has killed 71 people in total, but his true number of victims could be in the 100s. Filho could be described, according to psychiatrists, as a psychopath: someone with no remorse and no compassion for others. However, psychopaths do not develop affection; there are chances that he was developing some towards his mother and ex-girlfriend, describing him as a sociopath, for wanting to avenge their deaths. Psychiatrists diagnosed him as paranoid and antisocial.
