Argentine President Cristina Fernandez interrupted her agenda for two days due to the death of the mother of the head of state’s predecessor and late husband, Nestor Kirchner, officials said Monday.

Maria Juana Ostoic died Sunday in Buenos Aires at the age of 92.

Ostoic was admitted to a hospital in the Argentine capital last November and had been under the care of Alicia Kirchner, the sister of Nestor and social development minister in Fernandez’s cabinet.

Ostoic was born in the Chilean town of Punta Arenas, where she lived until 1945, when she met Argentine Carlos Kirchner, whom she married and with whom she had three children: Alicia, Nestor and Maria Cristina.

Her remains were to be transported on Monday to the mausoleum in the remote southern city of Rio Gallegos, where they will be interred along with those of Nestor Kirchner, who died of a heart attack in October 2010.
