"Charles Crenshaw completed his residency at Parkland and went on to a distinguished career at John Peter Smith Hospital in neighbouring Fort Worth, where he established the surgery department. When he became chairman emeritus in 1992, he had time to write his memoir of that day in Dallas—JFK: Conspiracy of Silence (1992)—adding his information to the record. This contradicted the official view that Oswald had acted alone.
"Crenshaw did not expect the firestorm that followed. One day his book was the number one paperback on the New York Times bestseller list; soon it dropped off the charts when the Journal of the American Medical Association held a press conference denouncing his book. Crenshaw asked for space for a rebuttal and then for a letter to the editor, but was denied. Eventually he sued the American Medical Association and won a settlement. He was dismayed that, although he had built a reputation as a skilled and caring surgeon, colleagues came out against his book.
"In the last year of his life, Trauma Room One: The JFK Medical Coverup Exposed (Paraview Press, 2001) was published. In this, Crenshaw expanded on his first book and included photographic evidence that showed Kennedy had been shot twice from the front, not once from the back as the Warren Commission concluded. Oliver Stone, who produced the film JFK, wrote an introduction praising the book."
