Father Juan Heraldo Viroche had received multiple death threats after denouncing the drug trade.
Because of fears for his life, he had sought and received a transfer to a new pastoral assignment, but was remaining in his parish to complete a novena.
His body was found hanging in his rectory.
The Archdiocese of Tucuman issued a statement: “We expect prompt clarification of the facts and trust in the action of the justice system, with which of course we will be cooperating in everything that depends on us.”
