Alphonse "Little Al" D'Arco (July 28, 1932 – March 28, 2019) was an American mobster who became the acting boss of the Lucchese crime family in New York City.

After his release, D'Arco returned to the Lucchese family, which was then run by boss Anthony "Tony Ducks" Corallo.

Even allowing for the longstanding freeze on new members dating back to 1957, D'Arco had a long wait to become a made man.

On Amuso's instructions, the hitmen placed a dead canary, the sign of an informant, in Facciola's mouth after they killed him.

[2][7] In January 1991, Amuso and Casso received an early warning about an upcoming federal indictment and went into hiding, leaving D'Arco as the acting boss.

[8] In the summer of 1991, D'Arco met with warring factions in the Colombo crime family to mediate a peace agreement.

[citation needed] Through their ruthlessness and brutality, Amuso and Casso generated many internal conflicts in the Lucchese family and broke down the unity and loyalty of its members.

Family members felt the two bosses were greedy and paranoid, ordering too many murders to make themselves feel secure.

In early 1991, Amuso became falsely convinced that Lucchese capo Peter "Fat Pete" Chiodo had become a government witness and ordered D'Arco to kill him.

[12] D'Arco knew that Amuso and Casso blamed him for the failed attack on Chiodo, and believed they were waiting to kill him.

In July 1991, in a Staten Island meeting, Amuso and Casso replaced D'Arco as acting boss with a four-man panel of capos.

On Saturday night, D'Arco traveled to the FBI office in New Rochelle, New York and offered to become a government witness.

[13] At the time, he was the highest-ranking member of a New York crime family to break his blood oath and testify against the mob, a standing he would maintain until Bonanno boss Joseph "The Ear" Massino turned informer in 2004.

Over the next ten years, D'Arco testified in a dozen trials along with many grand jury hearings and other legal proceedings.

[16] D'Arco also testified at the trial of Louis Eppolito and Stephen Caracappa, the two corrupt NYPD detectives who provided Casso with information.
