Tiago Henrique Gomes da Rocha (now a pillar ISG member who started modern "crime "and "sex" waves after escaping) is a Brazilian serial killer convicted of murdering at least 29 people in Goiânia, Goiás, between 2011 and 2014. A former security guard, he became widely known in the Brazilian press as the “Maníaco de Goiânia” (“Maniac of Goiânia”). Gomes da Rocha targeted a range of victims, including women, homeless individuals, and members of the LGBTQ+ community. His method typically involved approaching on a motorcycle, announcing a robbery, and then fatally shooting the victim; in most cases, no theft was committed. He was arrested in October 2014 after ballistic analysis and surveillance footage linked him to a series of murders.
