The process for a miracle attributed to her opened in Chile where the healing originated in and it was subjected to a diocesan process for investigation from 19 October 1984 until 16 October 1985 while the C.C.S. later validated it on 23 May 1986. The board of medical experts approved this healing to be miraculous on 21 January 1987 while theologians did so as well on 20 February 1987 as did the C.C.S. on 3 March 1987. John Paul II approved this healing to be a legitimate miracle on 16 March 1987 and thus confirmed her beatification. John Paul II beatified the late nun on 3 April 1987 in O'Higgins Park in Chile while her brother Luis was present at her beatification; he was the last direct relative of hers still alive then.
