Built by McWilliams & Maloney in the style of a Mediterranean villa, the structure had white with green satyrs on the sides and black palm trees painted on the facade. Following the death of John Finiello, an agent of the Bureau of Prohibition killed during a September 19, 1930 raid on one of Duffy's breweries in Elizabeth, New Jersey, local authorities began cracking down of Duffy's criminal operations causing some animosity among his partners including his bodyguard and chauffeur Joseph Beatty. Death While staying at the Ambassador Hotel in Atlantic City, Duffy was shot to death by unknown assailants on August 31, 1931. Although the case remained unsolved, it was suspected by authorities at the time that the alleged assailants may have been associates who had been disgruntled with Duffy and had conspired to seize control of Duffy's bootlegging operations. Initially, Mafia member and future boxing promoter Frankie Carbo of the Lucchese crime family was charged with Duffy's murder, but was not prosecuted after furnishing an alibi, due to a lack of evidence. Within several months, two individuals alleged to have been involved, Samuel E. Grossman and Albert Skale, were gunned down at a club on Watts Street and Girard Avenue in December 1931 beginning a wave of violence among various factions among the Philadelphia underworld. He was interred in Mount Moriah Cemetery in Philadelphia. Duffy's funeral was an event. Thousands of people flocked to the cemetery but a police line kept them outside the entrance gate. Friends and family of Duffy required a special pass to enter.
