Marina Oswald è nata il 17 luglio 1941. Luogo di nascita: Molotovsk, Arkhangelskaya oblast, RSFSR, USSR [ora Severodvinsk, Russia]. È stata sposata con Kenneth Jess Porter e Lee Harvey Oswald.
Oliver Stone's JFK - Un caso ancora aperto (1991) portrayed her as having been polished and pampered by
the government and instructed on how to answer questions to make her
late husband Lee Harvey Oswald look like a psychotic. At the time the film was
released, Marina made it known that this was absolute fiction.
