On April 7, 1972, around 4:30 a.m., Gallo and his family entered
Umbertos Clam House in Manhattan's
Little Italy to celebrate his 43rd birthday with sister Carmella, wife Sina, her daughter Lisa, his bodyguard Peter "Pete the Greek" Diapoulas and Diapoulas' girlfriend. Earlier that evening, the Gallo party had visited the
Copacabana with Orbach and his wife, Marta, to see a performance by comedian
Don Rickles and singer
Peter Lemongello. Once at Umbertos, the Gallo party took two tables, with Gallo and Diapoulas facing the wall. Colombo associate Joseph Luparelli claimed he was sitting at the bar, unbeknownst to Gallo. When Luparelli saw Gallo, he claimed he immediately left Umbertos and walked to a Colombo hangout two blocks away. After contacting Yacovelli, Luparelli said he recruited Colombo associate Philip Gambino, Genovese soldier Carmine "Sonny Pinto" DiBiase account of the murder was offered by
Frank Sheeran, a hitman and
labor union boss. Shortly before his death in 2003, Sheeran claimed that he was the lone triggerman in the Gallo hit acting on orders from mobster
Russell Bufalino, who felt that Gallo was drawing undue attention with his flashy lifestyle. Former Colombo family captain
Michael Franzese also disputes that Sheeran was the killer when reviewing the scene depicting the assassination in
The Irishman, claiming that he knows "for a fact what happened there" based on his personal involvement with the Mafia at the time. Gallo's widow later stated that she remembered the attack involving multiple men, all of whom were short and appeared to be Italian. Sheeran, on the other hand, was of mixed Irish-Swedish descent and 6'4". Looking for revenge, Albert sent a gunman from
Las Vegas to the Neapolitan Noodle restaurant in Manhattan, where Yacovelli,
Alphonse Persico and
Gennaro Langella were dining. However, the gunman did not recognize the mobsters and shot four innocent diners instead, killing two of them. After this assassination attempt, Yacovelli fled New York, leaving Persico as the new boss. The Colombo family, led by the imprisoned Persico, was plunged into a
second internecine war, which lasted for several years, until a 1974 agreement allowed Albert and his remaining crew to join the Genovese family. An increasingly paranoid Luparelli fled to California, then contacted the
Federal Bureau of Investigation and reached a deal to become a government witness. He implicated the four gunmen in the Gallo murder. However, police could not bring charges against them; there was no corroborating evidence and Luparelli was deemed an unreliable witness. No one was ever charged in Gallo's murder. In October 1975, the
New York City Department of Water Resources began to replace the sewer on the "Gallo block" of President Street with a system designed to connect to a new
sewage treatment plant in Red Hook. When a house at 21 President Street collapsed on December 3, 1975 (resulting in the death of one man), all work on the project stopped for more than eighteen months, leaving an "open trench in the middle of the street, [...] braced with steel and filled with stagnant water" due to an ensuing pump failure; this compromised the foundations of every building on the block and the remaining buildings on an adjoining stretch of Carroll Street, compounding the effects of probable earlier damage stemming from the construction of the
Brooklyn–Battery Tunnel and the depressed alignment of the
Brooklyn–Queens Expressway on nearby Hicks Street. Gallo crew member Frank DiMatteo has speculated that "lawyers and corrupt politicians [...] decided to turn the whole block into a stinking shithole until no one could live there anymore" in an effort to rid the area — by now convenient to the
gentrifying enclaves of Carroll Gardens and
Cobble Hill — of remaining Gallo associates. According to DiMatteo, only four buildings on the block were owned by the Gallo crew: "The rest were all owned by innocent people who'd had those buildings in their families for generations. [...] The Law didn't care. They got what they wanted." As many as 33 buildings on the block were subsequently condemned and replaced with new housing, with none of the Gallo-era buildings are extant today. ==Gallo crew==
