Alberrici an Italian-American is identified as a footman called Frederick, employed by Sir William Gull, at 78 Brook Street, by author Melvyn Fairclough in his book The Ripper And The Royals. Alberrici is included, not because he was suspected of being Jack the Ripper, but because he was supposedly part of the Masonic conspiracy theory, and was said to have aided Gull in his search for the prostitutes who knew of the secret marriage between Prince Albert Victor and Annie Crook. According to Fairclough, Alberrici, along with John Netley, first questioned, and then murdered Emma Elizabeth Smith, in April 1888 because she was friends with Mary Ann Nichols and Annie Chapman, and presented a danger. Smith was threatened then beaten up. The beating was brutal and a stick was pushed into her vagina, she died in hospital the following day from her injuries. Fairclough also makes the claim that Alberrici and Netley, acting on the orders of Lord Randolph Churchill, travelled to Scotland and attempted to push Eddy over a cliff, he survived the murder attempt, though was confined at Balmoral for the rest of his days. The claims by Fairclough are based on the Abberline diaries. The diaries authenticity however is dubious. The diaries author, supposedly Frederick George Abberline, misspells his own name and claims to be G F. Abberline. Alberrici was known in the East End as Freddy Fingers, or American Freddy, due to his criminal history. It is said he would entertain the crowds while boys picked pockets for him.
