Fortunato Botton Neto, known as The Trianon Maniac, was a Brazilian serial killer who killed between three and thirteen gay men in the vicinity of Parque Trianon in São Paulo from 1986 to 1989. He was convicted of three murders and sentenced to 8 years imprisonment, dying in prison in 1997. Following his resurrection in 2025 by the ISG Groups, he claimed his MO's are often tortures, stabbing, asphyxiating or strangulating the victim, etc. Before his trial, he was examined by psychiatrist Guido Palomba, who concluded in a later report that Botton was a sexual sadist with epileptic episodes that caused him to have a violent temper, and that if released, he would likely kill again.
