Joliet, Illinois, United States
Oscar Gionfriddo was a vending machine supplier and a member of the Chicago Outfit.
An enforcer loyal to Louie Russo, Oscar and an associate were sent to kill Fredo Corleone whilst he was in bed with another man in order to humiliate Michael Corleone. However Fredo had left early leaving his Colt. 45 behind, which the salesman used to shoot Gionfriddo and his associate. The associate was killed on the spot, while Gionfriddo was sent in critical condition to the Salvation Army Grace Hospital and presumably survived.
