Assistant Chief Constable Sir Melville Macnaghten named Druitt as a suspect in the case in a private handwritten memorandum of 23 February 1894. Macnaghten highlighted the coincidence between Druitt's disappearance and death shortly after the last of the five murders on 9 November 1888, and claimed to have unspecified "private information" that left "little doubt" Druitt's own family believed him to have been the murderer. Macnaghten's memo was eventually discovered in his personal papers by his daughter, Lady Aberconway, who showed them to British broadcaster Dan Farson. A slightly different abridged copy of the memo found in the Metropolitan Police archive was released to the public in 1966. Farson first revealed Druitt's initials "MJD" in a television programme in November 1959.
