The story of JFK, Oswald and Fort Worth is about more than gravestones or addresses. It’s about Fort Worth people – the hundreds here who went to one school or another with Lee in the Class of 1958, or who knew Marguerite, Marina or June. It’s also about people who may have known about Oswald’s anger, or inadvertently enabled his plan. “If you think there was a conspiracy – and that’s ‘if’ – then it had to include Fort Worth, because Kennedy was in Fort Worth as well as Dallas that day,” UVA professor and Kennedy historian Larry Sabato said Saturday after a Sixth Floor program.
