The Informant Files: Alphonse D'Arco, the Acting Boss Who Flipped
Mobsters DailyAlphonse "Little Al" D'Arco was the acting boss of the Lucchese family, running the streets for the fugitive Vic Amuso and Gaspipe Casso — and in 1991 he became the highest-ranking American mobster ever to cooperate with the government, because he was certain the paranoid regime he served was about to murder him.
The acting boss who saw the hit coming
D'Arco's break came at a meeting where he spotted what he believed was a gunman positioned to kill him — a signature Casso move in a family devouring its own. He fled to the FBI instead. His path follows the template Valachi cut in 1963, at a rank Valachi never approached — and it ran parallel to horrors like Greg Scarpa's double life.
What his testimony did
D'Arco's cooperation helped convict Amuso himself and dozens more, and it proved a boss-level man could flip and live — a door later informants walked through. He died in 2019, having outlived the family he ran.
