Paul Prosano, who prosecutors said goes by the street name of "Tony Pro," was convicted in December of crimes including robbery and the interstate transportation of stolen property.
He was sentenced Wednesday in U.S. District Court by Judge Kari A. Dooley.
March 2020 robbery in Stamford
According to prosecutors, Prosano and two other men robbed Marco Jewelers in Stamford in March 2020, getting away with between $360,000 and $400,000 worth of jewelry.
Police found the store owner, Mark Vuono, dead in front of the store's open safe.
Prosecutors said surveillance video showed Prosano driving the other two men, Robert Rallo and Thomas Liberatore, to the store.
The men were arrested after police found the car in Staten Island and put it under surveillance. Authorities said they later recovered jewelry from the robbery, including 23 pairs of earrings and three rings that were found inside Prosano's home.
Where are Rallo and Liberatore?
Rallo, who was charged with firing the fatal shots, is serving a 40-year sentence on charges including using a firearm to cause a death during a robbery.
Liberatore, who was also convicted of federal robbery charges, is awaiting sentencing.
Prosecutors said Prosano, of Brooklyn, has a criminal history of robberies dating back more than 40 years. They said he met his co-defendants while they all were serving time in New York.
