David Carradine’s brothers, Keith and Robert Carradine, spoke out publicly today for the first time since the Kung Fu actor’s death on June 4 in a Bangkok hotel room. According to ABC News, Keith, also an actor (Dexter, Nashville), called his brother’s passing a “devastating loss.” Robert Carradine requested a moratorium on speculation into the cause of David’s death until “the investigation is fully completed.”
