Chuck Binder, Carradine's manager, tells us he firmly believes Carradine did not take his own life -- nor does he think David died accidentally. Binder says the family has been told Carradine's hands were immobilized by the rope.
Carradine was found by a hotel maid Thursday morning with a rope tied around his neck and another around his genitals in a Bangkok hotel room.
UPDATE: Thai police are now recognizing David's death may not have been a suicide, by saying, "It is unclear whether he committed suicide or not or [whether] he died of suffocation or heart failure." Police say he could have died from an "accidental suffocation."
UPDATE: We've been told by the U.S. Embassy in Bangkok that David's body was shipped back to the States Friday evening (Thailand is 14 hours ahead of PST).
