a bone saw. >> jamal khashoggi's body was dismembered, chopped up into small pieces -- >> a saudi autopsy expert tells the men, put on headphones and listen to music. presumably to drown out the sound of the saw. a khashoggi look-alike can be seen leaving the consulate. >> same clothes, same glasses and beard, everything, except the shoes. >> saudi arabia vehemently denies knowing anything about khashoggi's disappearance. >> as details began to emerge, the saudis said a fight had broken out. >> the official saudi explanation that khashoggi's death was the result of a fistfight gone bad has been deemed laughable. >> finally the saudi government settled on one word, rogue. it was a rogue operation. >> the saudi foreign minister told fox news that this was a rogue operation. >> rogue elements may have been involved. >> they're going to say he was killed by rogue operatives. >> this rogue killer's explanation, this is absurd. >> sounded to me like maybe these could have been rogue killers, who knows.
