Truthout: The Real Roots of the CIA's Rendition and Black Sites Program

A good article with information on the fascinating case of Dimitri Dimitrov aka Donald Donaldson who claimed knowledge of a conspiracy in the JFK assassination.

About ten years after the JFK assassination, Dimitrov, operating sometimes under the aliases Lyle Kelly, James Adams, General Dimitre Dimitrov and Donald A. Donaldson, informed a number of people that he had information about who ordered the murder of JFK and who had committed the act. Reportedly, he had encountered the assassins while he had been imprisoned in Panama. He also told several people that he knew about military snipers who had murdered Martin Luther King. In 1977, Dimitrov actually met with US Sen. Frank Church, head of a Senate Committee investigating the CIA, and President Gerald Ford to share his information. Dimitrov said after the meeting that Ford had asked him to keep the information confidential until he could verify a number of facts. Immediately following the March 29, 1977, death of Lee Harvey Oswald's friend George de Mohrenschildt, Dimitrov became extremely frightened and contacted a reporter with a foreign television station who either mistakenly, or intentionally, revealed Dimitrov's name publicly on American television. Not long after this, Dimitrov disappeared in Europe where he had fled. He has never been seen or heard from since. Former CIA officials say privately, "Dimitrov was murdered" and "His body will never be found."
