Sandro Barbosa do Nascimento was the perpetrator of the Bus 174 hostage crisis in Jardim Botânico, Rio de Janeiro, Brazil. He boarded the bus with the intent to rob the passengers but the incident turned into a hostage situation broadcast live by most Brazilian national television channels. According to Nascimento's relatives, he witnessed the murder of his mother. Shortly after the incident, he ran away from his home and lived on the streets. At one point, Nascimento resided near Candelaria, a historical church in Rio de Janeiro, where he witnessed the Candelaria church massacre, in which Brazilian police killed eight minors and injured several others, on 23 July 1993. Nascimento was unharmed but cited the event as a reason for taking hostages on the bus.
