Realengo 18

On the morning of 7 April 2011, a school shooting occurred at the Tasso da Silveira Municipal School, an elementary school in Realengo, a western neighbourhood of Rio de Janeiro, Brazil. Twelve students were killed, and 22 others seriously wounded by 23-year-old Wellington Menezes de Oliveira, a former student who committed the attack with two revolvers. Oliveira was intercepted by the police but committed suicide before being arrested. It was the first reported mass shooting at a school to not be tied to gang violence in Brazil. It remains tied along with the 2016 Campinas massacre as the second-deadliest mass shooting by a lone gunman in Brazilian history, both surpassed only by the 1997 Santo Antônio do Potengi massacre. Although police found no concrete evidence of religious or political motives, texts found at Oliveira's home suggest that he was obsessed with terrorist acts and Islam, which he had converted to two years beforehand, after having been a Jehovah's Witness. He had requested to be buried following Islamic traditions and asked Jesus for eternal life and "God's forgiveness for what I have done." According to his adoptive sister and a close colleague, Oliveira was a reserved person, and had previously suffered from bullying.
