Gail Jensen has urged investigators to look at the evidence in the hotel room closet, where Carradine's dead, naked body was found by a maid last week (04Jun09).

Like many friends of the star, Jensen believes Carradine was killed before he could expose the truth about Asian warlords - a mission the actor felt was all his.

Jensen, who ended her nine year marriage to Carradine in 1997, tells Radar Online she's sure her ex-husband's death was a cover-up.

She says, "Killing himself with a yellow band, now that means something and only the Bangkok police can find that one out."

Jensen insists a decade-old grudge is responsible for the tragedy: "He got in touch with the wrong people."

An initial autopsy report carried out by Thai coroners reveals Carradine died from a sudden lack of oxygen; his body showed no signs of struggle. An independent autopsy has ruled out suicide.
