The Pallottines of San Patricio

In the early hours of Sunday 4 July 1976 the Pallottine priests Alfredo Leaden, Alfredo Kelly and Pedro Dufau and the seminarians Salvador Barbeito and Emilio Barletti were killed in the parish house of San Patricio, Belgrano. The Pallottines had come to Argentina from Ireland to serve Irish immigrants, and the five are remembered together as a community. Their own Irish links differ. Leaden's parents, Patricio Leaden and Brígida Ussher, were of Irish descent; he studied at the Pallottine seminary in Thurles, Co. Tipperary, and a 2006 provincial declaration calls him delegate of the Irish Pallottines. Kelly, the parish priest, was the son of Juan Kelly and Elisa Casey, with no county traced; he had been the first parish priest of St Patrick's, San Antonio de Areco. Dufau was not of Irish descent but studied in Thurles and treated Ireland as a second home. Nothing found links Barbeito or Barletti to Ireland.

The killings came in one of the worst weeks of the conflict. The military government blamed left-wing guerrillas; a 2008 Irish Times article said the evidence pointed to a government-linked death squad. Shortly before his death Kelly had criticised parishioners for attending auctions of property taken from the disappeared, and some parishioners then denounced him as a communist. Pope Paul VI sent a letter of protest. In 2005 the journalist Horacio Verbitsky cited Cardinal Aramburu as saying the Church knew security forces had killed the priests.

As of June 2026 no one has been convicted. A 2006 charge against members of an ESMA task group was not upheld on appeal; the case was reopened in 2013 after survivors' testimony; and since 2022 the federal judge Daniel Rafecas has examined a Federal Police reprisal hypothesis, summoning four former officers for questioning in late June 2026. That hypothesis is not established. Eduardo Kimel's 1989 book La masacre de San Patricio criticised the original judicial handling, and in 2008 the Inter-American Court of Human Rights ruled that his libel conviction violated his rights.

Three of the priests are buried in Mercedes. A Mass is said each 4 July at the Belgrano parish; on the 50th anniversary in 2026 Archbishop García Cuerva presided and a memorial exhibition opened at the city legislature. A canonisation cause is open; sources date its opening to 2001, 2005 or 2006. In 2024 the Pallottines gave Pope Francis a painting of the killings.
