Corleone family
In "The Godfather Part III", set 20 years later, Connie has become one of Michael's closest advisors. She encourages Michael to bring Sonny's illegitimate son Vincent Mancini into the Corleone family and support him in his feud with Joey Zasa. When Michael suffers a diabetic stroke following an attempt on his life, Connie and Michael's assassin Al Neri give Vincent the approval to kill Zasa, who was complicit in the attack. Michael is furious that she gave an order behind his back, but she maintains that it was necessary to strike fear into his enemies. Connie travels with the Corleone family to Palermo, Sicily to watch Anthony's operatic debut. She tells Vincent to prepare a counterattack if Michael is killed. She then stands at Michael's side when he retires and names Vincent his successor. She attends the opera, along with the entire Corleone family. On discovering that her godfather Don Altobello is the mastermind of the plot against their family, she kills him by giving him a gift of poisoned cannoli. Connie is distraught when her niece Mary is killed by an assassin who intended to kill Michael.
