William "Billy" Leotardo was a soldier in Phil Leotardo's crew and Phil's younger brother and dim-witted partner in crime who is on friendly terms with Tony Blundetto. Billy killed Lorraine Calluzzo and Jason Evanina with his friend Joey Peeps. He sells computer printer toner cartridges out of the back of a truck that he has ordered for the Esplanade construction site offices. Following Carmine Lupertazzi's death, a power struggle between Johnny Sack and Little Carmine ensued. One side was led by Carmine's underboss, Johnny Sack, while the other was ostensibly led by Carmine's son and Miami Capo, "Little Carmine" Lupertazzi, although it is likely that Consigliere Angelo Garepe and Capo Rusty Millio were the real power behind this faction. Joe was killed soon after and Billy took part in the response - a hit on Angelo Garepe. Finally, Billy himself was killed by Tony Blundetto in revenge for the death of his friend Angelo, causing lasting distress to his brother Phil, who was wounded in the attack, and held his brother in his arms as he died on the street.
