“A theory held that an anti-Castro group was behind the assassination…. Sylvia Orenstein, who was born in New York City on 22nd July, 1921, promoted this theory while taking evening classes at Brooklyn College. The marriage to her professor, James Meagher, accounted for her name change. As Sylvia Meagher, she became a research analyst at the UN’s World Health Organization. Her book, “Accessories After the Fact: The Warren Commission, the Authorities, and the Report After the Fact,” published in 1967, supported this widely held theory. In her book, she expressed that she was not convinced that Lee Harvey Oswald had been a lone gunman. Her conclusion was that the Warren Commission had attempted to cover-up important details of the actual people behind the assassination. In 1980, Meagher co-authored another book named “Master Index to the John F. Kennedy Assassination Investigations.” Meagher continued to believe that John F. Kennedy had been killed by Anti-Castro exiles until her death at St. Vincent's Hospital in New York City, at the age of 67, on January 14, 1989.” U S HistoryKennedy AssassinationConspiricy Theories Author:Captain Hank Bracker, "The Exciting Story of Cuba"
