David Carradine's Death -- Murdered by a secret Kung Fu society?

David Carradine's family speaks out for the first time since his death and they question the original autopsy results which suggest that David Carradine might have been killed as he tried (and failed) one deadly sex play called auto-erotic asphyxia (heck, even Wikipedia has an article about it, "erotic asphyxiation").

This particular ABC News article suggests that David Carradine might have been murdered by a secret Kung Fu society. Hmm. After re-watching a YouTube episode of Carradine's pilot movie, "Kung Fu" (1972)--Part 1 HERE--well, I can accept the possibility if the extremists out there might have been outraged about the show. But to the extent to kill him?

The movie, "Kill Bill" now seems to have an even more sinister meaning...
