On May 29, 1970 at noon, Aramburu was snatched from his apartment in Buenos Aires by two members of Montoneros posing as young army officers. Montoneros dubbed the kidnapping "Operación Pindapoy", after a company that produced citrus in the 1960s. Aramburu's disappearance kept Argentinian society on tenterhooks for a month before it was discovered that Aramburu had been murdered three days after his abduction, following a mock trial and his corpse hidden inside a farmhouse near Timote, Carlos Tejedor, in Buenos Aires Province. He had been shot twice in the chest with two different pistols. Following his arrest, convicted terrorist Mario Firmenich took credit for the kidnapping and assassination.
