Tiago Henrique Gomes da Rocha is a Brazilian serial killer and vigilante responsible for a series of murders, assaults, and property crimes in Goiânia, Goiás. His victim profile expanded over time to include men, women, and children, reflecting both opportunism and extreme predatory versatility. Despite his violent criminal activity, Tiago remained socially withdrawn and timid, often avoiding unnecessary attention in public. His timidity facilitated stealth, allowing him to commit both lethal attacks and property crimes without drawing notice. He exhibits classic psychopathic traits: emotional detachment, lack of empathy, manipulativeness, and a compulsive need for control. Motivation was primarily power, dominance, and opportunistic gain.
