The day comes when Michael will be appointed godfather to Connie and Carlo's baby son. While Michael is in the church, his grand plan unfolds. The Corleone caporegimes carry out a violent massacre of all the heads of the New York Families, as well as Moe Greene in Las Vegas. After the baptism is over, Tom Hagen also has Tessio killed. Michael, who has discovered that Carlo aided the Barzini family in killing Sonny, has his brother-in-law strangled to death. Later, as Michael is preparing to move the Corleone family to Las Vegas, his hysterical sister Connie lashes out at him for killing Carlo. Kay asks Michael if Connie's accusations are true, and Michael lies to his wife, assuring her that he had nothing to do with Carlo's death. Relieved, Kay walks out of Michael's office to get a drink. When she looks back at her husband, his caporegimes are kissing his hand and calling him "Don Corleone".
