who did michael kill at the end of the godfather
Michael Corleone Vito semi-retires in 1954, and Michael becomes operating head of the family. He attempts to buy out casino owner Moe Greene's stake in the Las Vegas casino that the Corleones bankrolled, intending to move the family to Nevada and legitimize all Corleone enterprises, but Greene refuses to sell. Before his death in 1955, Vito warns Michael that Emilio Barzini, head of a rival family, will likely attempt to assassinate Michael under the pretense of establishing peace between the families. Vito tells Michael that whoever approaches him about the meeting is the traitor within the family. When caporegime Salvatore Tessio unknowingly exposes his complicity with Barzini by arranging the meeting, Michael sets the plan in motion to murder the other New York Mafia heads: Barzini, Philip Tattaglia, Carmine Cuneo, and Victor Stracci, as well as Moe Greene. The plot unfolds on the same day Michael stands as godfather to Connie's newborn son. Later the same day, Tessio and Carlo Rizzi, Connie's abusive husband who conspired in Sonny's murder, are executed. In one stroke, Michael re-establishes the Corleone family as the nation's most powerful crime family, and makes a reputation for himself as being even more cunning and ruthless than his father.
