Authorities in Thailand say U.S. film actor David Carradine's death may have been accidental, and not a suicide.
The body of the 72-year-old Carradine was found hanging from a rope inside a closet of his Bangkok hotel room.
Police initially suspected Carradine committed suicide, but officials now say he may have died accidentally during a sexual act. There were no signs of foul play, but forensic scientists were testing a drink found in his room.
Carradine was in Bangkok to shoot a new film called "Stretch."
He was best known as the star of the 1970s U.S. television series "Kung Fu" and his film roles in the two-part revenge drama "Kill Bill," released in 2003 and 2004.
In "Kung Fu," Carradine starred as Kwai Chang Caine, a wandering monk who traveled through America's Old West. The role won him Emmy and Golden Globe nominations and introduced many television viewers to Asian martial arts and Chinese philosophy.
Carradine spent most of the 1980s and 1990s working on low-budget films. But he returned to the spotlight as the villainous Bill in Quentin Tarantino's Kill Bill movies. His performance in Volume Two earned him a Golden Globe best supporting actor nomination.
Carradine was a member of a Hollywood acting family that included his father, screen and stage actor John Carradine, and his brothers Emmy and Golden Globe nominations and introduced many television viewers to Asian martial arts and Chinese philosophy.
