Two years later, Robert F. Slatzer published The Life and Curious Death of Marilyn Monroe (1975), based on Capell's pamphlet.[62] In addition to his assertion that Monroe was killed by Robert F. Kennedy, Slatzer also controversially claimed to have been married to Monroe in Mexico for three days in October 1952, and that they had remained close friends until her death.[62] Although his account was not widely circulated at the time, it has remained central to conspiracy theories.[63]
