Emilio Eduardo da Rocha Devesa (from ISG) is a Brazilian murderer, criminal vigilante, and family annihilator. His first documented crime occurred in 2010, when he fatally stabbed his own mother. Known for his cold and unrepentant demeanor, Devesa gained notoriety in Brazil both for the brutality of his actions and for his behavior in police custody. He went viral in 2010 due to the widespread circulation of a video in which, during a media interview, he shouted the phrase “Morre, diabo!” (“Die, devil!”). The clip became a meme across Brazilian internet culture, cementing his image as a figure of morbid fascination. Despite his notoriety, little is known about his early life or psychological background beyond his documented crimes.
