when does simon die in lord of the flies

Simon dies in Chapter 9 of "Lord of the Flies." He is killed during a chaotic ritual dance by the other boys who mistake him for the beast. Simon had just discovered that the "beast" was actually a dead parachutist and was on his way to inform the others when they attacked him in the chaos of the feast and storm. Even Ralph and Piggy are involved in the killing. His death symbolizes the loss of innocence and the triumph of savagery among the boys.
