How many people die in Hamlet?

There are eight individuals who die during the play, three of them offstage :

Hamlet himself, King Claudius and Queen Gertrude, Polonius, Laertes, Ophelia, and Rosencrantz and Guildenstern. Hamlet's father is dead before the play opens, and only his Ghost appears.

(It's also implied that the servant Reynaldo dies, although that has to be interpreted.)
