[1] Oliveira worked at Dom Pedro II Home, a retirement facility, where she was killed in 1993 after a man obsessed with her stabbed her 44 times when she refused his advances.
[2][3][4] Oliveira's beatification received the approval of Pope Benedict XVI, who determined that she was killed in defensum castitatis (in defense of chastity).
[6] Oliveira received her baptism on 7 January 1954 in the parish of Saint John the Baptist in the Chapel of Olho D'Água from Monsignor Júlio Alves Bezerra.
In 1986 she attended a vocational movement of the Vincentian Sisters and requested joining them at the end of 1987; the Archbishop of Natal Nivaldo Monte granted her the sacrament of Confirmation on 28 November 1987.
She began to work at the shelter titled Don Pedro II Home in Bahia on 29 January 1991 to aid older people and the poor; she went on a retreat that same month while the forum was dedicated to the charism of Saint Vincent de Paul.
[5] Those around her convinced her to report it and on 30 March 1993 the official of the shelter – Margarita Maria Siva de Azevedo – rebuked him; Augusto responded on 5 April in purchasing a machete.
On 9 April 1993 de Oliveira participated in the Way of the Cross and returned to the shelter to serve breakfast at the Dom Pedro II Home.
[6] The beatification process commenced in Brazil on 19 October 1999 under Pope John Paul II after the Congregation for the Causes of Saints declared "nihil obstat" ('nothing against') to the cause while also acknowledging her as a Servant of God.
The celebration was held in Brazil on 2 December 2007 and Cardinal José Saraiva Martins presided as the delegate the pontiff appointed in his stead.
