Dr. Robert McClelland provided a detailed account of his experience treating President John F. Kennedy and Lee Harvey Oswald after their assassinations in 1963. As one of the doctors present in the operating room, he described finding the back of JFK's skull missing and his cerebellum fallen out, indicating a fatal wound. He also recounted Jacqueline Kennedy's composed farewell to her husband. Two days later, McClelland treated Oswald after being shot by Jack Ruby, but Oswald died from heart failure without revealing any conspirators. While most Americans doubted the lone gunman conclusion, the full truth may not be known until a congressional report is released in 2029.
