A Chilean appeals court has upheld the conviction of a retired brigadier general and a former civilian air force employee in the killing of two Americans shortly after the 1973 military coup that overthrew democratically elected President Salvador Allende.

The Appeals Court of Santiago on Saturday confirmed the 7-year sentence given to retired Gen. Pedro Espinoza Bravo as the mastermind in the killings of documentary filmmaker Charles Horman, 31, and journalist Frank Teruggi, 24. The court also ratified the 2-year sentence for retired civilian air force employee Rafael Gonzalez Berdugo for his complicity in Horman's death.

The Americans' deaths were the subject of the 1982 film "Missing" by Constantin Costa-Garvas, with Jack Lemmon playing Horman's father.

Espinoza Bravo and Gonzalez Berdugo are currently behind bars in other criminal cases.
