by Pinochet's regime (along with a couple of his friends), in the movie "Missing" with Jack Lemmon playing Charles Horman's father, and Cissy Spacek playing his wife Joyce. They re-ran it Saturday night, and I'm sure you'll see it being offered again for a while.
Here's a photo of the real couple...

Early years
Horman was born and raised in New York City. He graduated from Harvard University in 1964 and worked for a number of years in the US media. In 1972, he settled temporarily in Chile to work as a freelance writer.
Imprisonment and death
On September 17, 1973, six days after the US-backed military takeover, Horman was seized by Chilean soldiers and taken to the National Stadium in Santiago, which had been turned by the military into an ad hoc concentration camp, where prisoners were interrogated, tortured and executed. One month later, Horman's body turned up in a morgue in the Chilean capital. A second US journalist, Frank Teruggi, met with the same fate.
At the time of the military uprising, Horman was in the resort town of Viña del Mar, near the port of Valparaíso, which was a key base for both the Chilean coup plotters and US military and intelligence personnel who were supporting them. While there, he spoke with several US operatives and took notes documenting the role of the United States in overthrowing the Allende government. This discovery led to his secret arrest, disappearance, and execution. Efforts by his family to determine his fate were met with resistance and duplicity by US embassy officials in Santiago, who knew he was dead and why he had been killed (c.f. Hauser).

Book, film, and television depictions of the case
The Horman case was made famous by the Hollywood film Missing (1982), directed by Greek filmmaker Costa-Gavras, starring Jack Lemmon and Sissy Spacek. The film was based on a book first published under the title "The Execution of Charles Horman: An American Sacrifice" (1978) by Thomas Hauser (it was later republished under the title Missing in 1982). When the film was released by Universal Studios, Nathaniel Davis, US ambassador to Chile from 1971 to 1973, filed a USD $150 million libel suit against the studio, even though he was not named directly in the movie (he was however named in the book).

Chile's famous folk/popular singer Victor Jara was also tortured and murdered at the National Stadium. They crushed his hands with the butts of their guns.
