According to Dinges, the FBI and the CIA were informed of their arrest. He quotes a cable sent from Buenos Aires by FBI agent Robert Scherrer on 22 September 1976, in which he mentioned that Michael Townley, later convicted for the assassination of former Chilean minister Orlando Letelier in Washington, D.C., had taken part in the interrogations of the two Cubans. On 22 December 1999, the former head of the DINA confirmed to Argentine federal judge María Servini de Cubría in Santiago de Chile that Michael Townley and Cuban Guillermo Novo Sampoll were present in the Orletti center. They had travelled from Chile to Argentina on 11 August 1976 and "cooperated in the torture and assassination of the two Cuban diplomats." Luis Posada Carriles, an anti-Castro Cuban terrorist, boasted in his autobiography, "Los Caminos Del Guerrero" (The Roads of the Warrior), of the murder of the two young men.
