Ronni Karpen Moffitt and Orlando Letelier were assassinated on September 21, 1976, when a car bomb detonated on Sheridan Circle in Washington, D.C. Letelier, a former Chilean ambassador and defense minister under President Salvador Allende, and Moffitt, a 25-year-old fundraiser for the Institute for Policy Studies, were killed by agents of Chile’s Dirección de Inteligencia Nacional (DINA). Rather than silencing their advocacy against Augusto Pinochet’s military dictatorship, the targeted killings galvanized international human rights campaigns and permanently altered global scrutiny of Operation Condor.
The 1976 Assassination and Operation Condor
According to investigative records and historical archives from the National Security Archive, the bomb was planted under Letelier’s car by DINA agents working in tandem with anti-Castro Cuban exiles. Letelier died almost immediately from his injuries, while Moffitt succumbed to her wounds at George Washington University Hospital. The attack marked the first instance of state-sponsored terrorism carried out by a foreign intelligence service in the United States capital.
The assassination operated under the umbrella of Operation Condor, a covert intelligence-sharing and assassination network established by South American military dictatorships in the 1970s. According to documents released by the Central Intelligence Agency, DINA chief Manuel Contreras directed the operation, utilizing international operatives to eliminate political dissidents living in exile across the Americas and Europe.
Legal Proceedings and the Quest for Accountability
The FBI launched an extensive cross-border investigation that quickly tied the bomb’s components to DINA operatives. Michael Townley, an American-born DINA agent who built the bomb, pleaded guilty in U.S. federal court in exchange for a reduced sentence and entered the federal witness protection program. In 1979, a U.S. federal court convicted DINA operations officer Juan Williams Rose and Cuban exiles Virgilio Paz Romero and Alvin Ross Diaz for their roles in the conspiracy.
According to the U.S. Department of State, diplomatic pressure forced the Chilean government to prosecute Contreras and his deputy, Pedro Espinoza. A Chilean military court initially shielded the higher-ranking officers, but Chile’s Supreme Court eventually convicted both men in 1995. Contreras and Espinoza served prison sentences in Chile for orchestrating the murders.
Amplifying the Human Rights Movement
The murders of Letelier and Moffitt shifted U.S. foreign policy toward the Pinochet regime, prompting Congress to cut off military aid and impose economic sanctions. According to the Institute for Policy Studies, Moffitt’s husband, Michael Moffitt, who survived the blast, dedicated subsequent decades to human rights activism alongside Letelier’s family. Memorials on Sheridan Circle gather activists annually to honor the victims, cementing their legacy as catalysts for international accountability and the global anti-dictatorship movement.
