Late movie star David Carradine's ex-wife is convinced the "Kill Bill" star's spirit is struggling to "cross over" because the true facts of his 2009 death have not been uncovered.

Thai authorities ruled the actor died of accidental asphyxiation alone in a Bangkok hotel room while performing a solo sex act, but friends and loved ones are convinced the star was murdered.

And Carradine's ex-wife Marina Anderson feels sure her late husband is trying to give her clues from beyond the grave as she continues to investigate his bizarre death.

She tells, "I definitely feel him around... I flew to Toronto and we moved in together... during the Toronto Film Festival and so every year (at about this time) it brings it all back.

"I've had pretty lucid dreams about him and it verifies my feelings that he's not only around but he can't cross over or doesn't want to because the truth hasn't come out yet. In a way I feel like he has literally been guiding me."
