Tiago Henrique Gomes da Rocha, also known as the Goiânia Maniac, was a Brazilian serial killer who, upon being arrested, confessed to having murdered 39 people, most of them women, between 2011 and 2014, in the city of Goiânia, Goiás. He later changed his mind and increased the number, saying it was between 50 and 56 people. He has worked as a security guard and is also considered a vigilante. At the same time, he is considered a "seductive psychopath" and claims that the groups he is a member of are prepared to kill anyone, enemy or opposition: whether they are "women" or not. He shows no remorse whatsoever, and together with Marcos Trigueiro, he earned the nickname "Stallions of 187".
