This latest edition of Smithsonian’s well-researched The Lost Tapes revisits the Seventies case of 19-year-old newspaper heiress Patty Hearst, who was kidnapped in 1974 by a ramshackle radical group calling itself the Symbionese Liberation Army. The granddaughter of publishing magnate William Randolph Hearst was held by the SLA for 19 months, during which she went from being held captive in a dark closet to participating in one of their bank robberies as an armed assailant. Lost Tapes includes audio recordings made by both Patty Hearst and her kidnappers, as well as newly unearthed vintage local news footage.
