I read mixed points of view, Christian say he dead but seem to have a weak story to base it on and Pagan say he not, but it's hard to tell if that because they just don't want him to be. So reading on the net has been almost pointless. From a historical point of view where did the story of Pan's death come from?
The Norwegian folklorist, Reidar Christiansen in his 1958 book, The Migratory Legends, described a widespread legend - ML 6070 "Fairies send a Message" and its related 6070B "The King of the Cats." This legend describes how a voice from the forest calls out that someone has died. Often that someone is the king of the supernatural beings, and it inspires a cat in a household to stand on its hind legs and to declare that he can now return home because he is now the king.
This legend is apparently old, as indicated by its widespread distribution and by the recordation of the similar literary story in the Classical world of a voice in the forest calling out that "Great Pan is dead.". A legend that probably pre-dates conversion became attached to the supposed death of a forest-dwelling supernatural being outside the Christian pantheon. By implication, since the pre-Christian monarch had died, his replacement (in this case, popularly believed to be Christ), could assume his role as monarch. But the legend originally had nothing to do with conversion to Christianity, and although this literary device was popular in the converted Classical world, the folk legend, having northing to do with Pan, survived into the early twentieth century.
