On January 31, 1976, Baruch Tenembaum was kidnapped by rightwing extremists belonging to the Triple A (Argentine Anti-subversive Alliance) a clandestine state terrorist organisation founded under the aegis of José López Rega, a sinister character of great influence during the government of President Isabel Martínez de Perón.
In a dramatic turn of events, his wife Perla volunteered as a hostage, and was also kidnapped herself.
