Friends and family of actor David Carradine, who was found dead this morning in his Thai hotel room, are now saying that they dispute Thai authorities' pronouncement that the 72-year-old committed suicide.  Director Adam Rifkin -- who worked with the actor -- has said he "find[s] it extremely hard to believe that ... [this] was done in by his own hand."   Meanwhile, Carradine's mother-in-law Betty Fraser also disputes the suicide claims, saying that "he was a very strong person and I don't think it's likely at all."

And now The Daily Mail is reporting that the death-by-hanging "accidental," per Carradine's spokesman Chuck Binder.  The rep also gave the following quote to TMZ.com: "We can confirm 100 percent that he never would have committed suicide. It was an accidental death. Everybody is in shock."
