On September 20, 1973, nine days after the coup d'état, Frank Teruggi, in the same way as
Charles Horman, was seized by the Chilean military at his home and taken to the
National Stadium in
Santiago, which had been turned into an
ad hoc concentration camp, where prisoners were interrogated and tortured and many were executed. In the film
Missing, by Costa-Gavras, Teruggi is depicted as a contributor for a small newspaper and friend of Charles Horman who had spoken with several U.S. operatives that assisted the Chilean military government. The film alleges that Horman's discovery of U.S. complicity in the coup led to his secret arrest, disappearance, and execution. American complicity in the Chilean coup was later confirmed in documents declassified during the
Clinton administration. The declassified documents mention Teruggi as one of the Chilean military executions and initially
U.S. embassy officials in Santiago released false information that he had returned to the United States. His body was later found in a Chilean morgue among the "unidentified bodies" of the victims of the regime. ==Book, film, and television depictions of the case==
