Stephen Newell was a low-level mob associate. That's the thumbnail description.
He was born and bred in Bushwick, Brooklyn. From the age of 10 he lived in Queens and much later moved to Staten Island. His uncle, Saverio "Sammy" Galosso, was a member of the Genovese crime family under Vincent "The Chin" Gigante. He died in 1986.
Stevie, earlier in his life, worked under John Gotti's son-in-law, Carmine Agnello, after Carmine became a member of the Gambino crime family. (Carmine is living somewhere in Ohio today, we've heard.) Agnello was married to Victoria Gotti at the time.
