David Carradine appeared to hang himself, and the Bangkok police think it was suicide. His friends, although, think it must have been auto erotic asphyxiation gone wrong. A man in his seventies still having so much life force (prana) to still be doing that, you just have to smile.
From what I've heard, he had a rope around his neck and one around his genitals.
I remember when the lead singer (sorry I can't remember his name!!!) from INXS died, I read where someone was saying the deal with the autoerotic asphyxiation is taking yourself to the very edge, where the pleasure is the most intense. There are a number of guys that go just a little over the edge and don't come back.
I've heard that the family is saying there may be foul play with David's death. However it happened, it's a tragedy.
