Was David Carradine's Death a Suicide?

I have just read that actor David Carradine's death might have been a suicide.

As it turns out he was found hanging in the closet of his hotel room, according to Bangkok police.

However, Carradine's spokesperson states the actor would never have taken his own life.

But The Telegraph cites an interview Carradine did in 2004 which states otherwise.

Meanwhile others suggest it wasn't suicide but rather auto-erotic asphxiation.

So who knows?

Preliminary autopsy reports won't be released for another 48 hours.
