Wellington Menezes de Oliveira (July 13, 1987 - April 7, 2011) was a brazilian school shooter, who killed 12 people and himself at Tasso da Silveira Municipal School, which is his previous school.
He had been a target for both verbal and physical bullying during his days there as he had a limp leg and described as 'strange'. However, he was kind and friendly. He was once thrown into a garbage bin by students. Inevitably, rage and resentment began to build inside him, which lasted until adulthood. When he could not take the psychological torture anymore, he snapped.
On the fateful day, Oliveira entered the school, by identifying as a former student and lying to the security guard that he was there to give a speech. Instead of giving a speech, Oliveira entered a classroom, and at first, he was very polite when he put his bag on a table. Then suddenly, things turned nasty. He took out his revolvers and began shooting everyone. Of the 12 dead, 10 were girls and one boy said that Oliveira only shot at boys to stun them while he tried his best to kill the girls. However, it may be due to the fact that the population of the class is predominately girls. Soon, the police arrived and Oliveira tried to shoot the cops, but he did not hit any of them. Soon he was shot in the abdomen and legs, where as a result he fell down a staircase. He then fatally shot himself in the head.
Oliveira was also obsessed with Islam, perceiving it as the 'only correct religion'. He also refers to the Virginia tech shooter, Seung-Hui Cho, as a brother and an icon for those who are oppressed by the majority.
Survivors from the scene of the school where Eric Harris and Dylan Klebold committed their shooting spree created a poster for the Municipal school, stating their feelings. Also, on the day of the Sandy Hook elementary school shooting, the municipal school held a vigil for the children killed.
