By the early 1980s, the Plaza Suite was a thriving establishment. Patrons often had to wait an hour to get in and the club featured high-profile live acts such as singers Chubby Checker and the Four Tops.
In 1982, Frank Fiala, a wealthy businessman and drug trafficker, paid Gravano $40,000 to rent the Plaza Suite for a birthday party he was throwing himself. Two days after the party, Gravano accepted a $1,000,000 offer from Fiala to buy the establishment, which Gravano had only valued at $200,000. The deal was structured to include $100,000 cash as a down payment, $650,000 in gold bullion under the table, and a $250,000 payment at the real estate closing.
Before the transaction was completed, Fiala began acting like he already owned the club. Upon leaving the Plaza Suite, Gravano called Garafola and set up an ambush outside the club, involving Garafola, Milito, D'Angelo, Nicholas Mormando, and Michael DeBatt in the plan. Later that night, Gravano confronted Fiala on the street as he exited the Plaza Suite among a group of people, asking, "Hey, Frank, how you doing?" As Fiala turned around, surprised to see Gravano, Milito came up behind him and shot him in the head. Milito stood over the body and fired a shot into each of Fiala's eyes as Fiala's entourage and the crowd of people on the street dispersed, screaming. Gravano then walked up to Fiala's body and spat on him.
Gravano was never charged for the crime; he had made a $5,000 payoff to the lead New York Police Department homicide detective Louis Eppolito to ensure that the investigation yielded no leads
Although Gravano evaded criminal charges, he incurred Castellano's wrath over the unsanctioned killing. Gravano attempted to lie low for nearly three weeks afterwards, during which time he called his crew together and made the decision to kill Castellano if necessary. Gravano and Milito were then summoned to a meeting with Castellano at a Manhattan restaurant. Castellano had been given the details of what Fiala had done, but he was still livid that Gravano had not come to him for permission to kill Fiala first. Gravano, however, was spared execution when he convinced Castellano that the reason he had kept him in the dark was to protect the boss in case something went wrong with the hit.
Fiala's murder posed one final problem for Gravano in the form of the Internal Revenue Service (IRS). The high publicity generated by the incident triggered an IRS investigation into Gravano and Fiala's deal for the sale of the Plaza Suite and Gravano was subsequently charged with tax evasion. Gravano was represented by Gerald Shargel and acquitted at trial.
D'Angelo was later killed by a Colombo family associate celebrating his having been proposed for membership. The killer was then murdered, himself, on orders from the Colombo family.
