In 1973, DeCicco and future Lucchese crime family underboss Anthony "Gaspipe" Casso were robbing diamond dealers and hijacking trucks throughout New York State.
DeCicco became heavily involved in labor racketeering with the International Brotherhood of Teamsters (IBT) Union Local 282.
The members of Local 282 delivered concrete and building materials to construction sites in New York City and Long Island.
A cocaine and alcohol user, Scibetta participated in several public fights and insulted the daughter of George DeCicco.
Finally, DeCicco recruited Gambino associates Anthony Senter and Joseph Testa, both members of DeMeo's crew, to murder their boss.
[citation needed] In late 1985, DeCicco and John Gotti conspired to murder Castellano and his new underboss, Thomas Bilotti.
Although DeCicco had enjoyed close ties with Castellano, he joined Gotti, Gravano, Joseph "Joe Piney" Armone, and Frank "Frankie Loc" Locascio in the murder conspiracy.
DeCicco tipped Gotti off that he would be having a meeting with Castellano and several other Gambino mobsters at Sparks Steak House on December 16.
[8] Just before 5:30 p.m. on Monday, December 16, Castellano and Bilotti were shot to death while exiting their Lincoln Town Car outside of Sparks Steak House.
[13]Gravano would later say in his autobiography, "Louie (Milito) had got pinched for something and was away for a short time when we made our move (the murders of Paul Castellano and Thomas Bilotti.)
On April 13, 1986, DeCicco was killed in Dyker Heights, Brooklyn, when his 1985 Buick Park Avenue was bombed following a visit to Castellano loyalist James Failla.
The bombing was carried out by Victor Amuso and Anthony Casso of the Lucchese family, under orders of Vincent Gigante and Lucchese boss Anthony Corallo, to avenge Castellano and Bilotti by killing their successors; Gotti also planned to visit Failla that day, but canceled, and the bomb was detonated after a soldier who rode with DeCicco was mistaken for the boss.
[14][15] In November 1997, author Jerry Capeci reported that Casso, now a government witness, revealed that the plotters selected Genovese associate Herbert Pate to kill Gotti with an improvised explosive device (IED).
Casso told investigators that the plotters decided to kill Gotti and DeCicco with a bomb in order to make the Gambinos think that Zips, or Sicilian mafiosi, were involved.
Although Sicilian gangsters are notorious for using bombs, they have long been forbidden in the American Mafia since they put innocent people at risk.
Casso also told authorities that Pate was selected because he had no links to the Gambino family and thus would not be recognized while staking out DeCicco.
[16][17] Supervising agent for the Drug Enforcement Administration (DEA), Edward Magnuson testified that a confidential informant had told him that Gotti was, "very angry relative to the murder of Frank DeCicco, and when he was out on bail, or when the trial was over, there was going to be a war, and John would take his revenge."
Gotti instructed all the Gambino made men and associates to attend DeCicco's wake, held over two days at a funeral home near the bombing site.
