Hugh McDonald was born in 1913. He attended the FBI National Academy and eventually became second in command at the Military Intelligence School at Fort McArthur.
In 1949 McDonald joined the Los Angeles Police Department. He held several posts and by 1963 was Division Chief, Los Angeles County Sheriff's Department. According to McDonald, he was "frequently granted leave to be of service to several government agencies". It was while he was on one of these jobs, Head of Security for Barry Goldwater, that he employed former ex-CIA agent, Herman Kimsey.
Soon afterwards, Kimsey told McDonald the story about Saul (Georgi Visko). Kimsey claimed that John F. Kennedy was killed on the orders of Nikita Khrushchev. The operation was planned by the KGB. Saul and Lee Harvey Oswald were both recruited to fire at Kennedy. Oswald was told to miss on purpose whereas Saul's job was to kill Kennedy. McDonald claims he interviewed Saul who backed-up this story. His book about the assassination, Appointment in Dallas, was published in 1975.
After the publication of the book, McDonald was contacted by Anatoli Cherenkov of the KGB. Cherenkov claims that Mikhail Tsymbal (KGB chief in Paris) had a meeting with Lyndon B. Johnson in Helsinki, Finland, in the summer of 1963. At this meeting LBJ was told that John F. Kennedy and his brother, Robert Kennedy, intended to have him prosecuted over the Bobby Baker affair. In order to save himself from being sent to prison, LBJ is told he will have to cover-up the assassination of Kennedy. According to Cherenkov, Johnson agreed to these demands. An account of this meeting appeared in LBJ and the JFK Conspiracy (1978).
Other books by McDonald include Black Sea Caper, The Blue Fox, Letter from Kiev, The Investigation of Sex Crimes, The Classification of Police Photographs and The Psychology of Police Interrogation.
Hugh McDonald died of a heart attack in about 1985.
