I don't believe we actually ever read anything about the prosecution claiming that Shelley's air was turned off in any of the numerous articles that were linked to. The first I recall of this part of the theory is in the 48 Hours episode and it was acted out by divers for the show. The video was not done by police divers and it was not evidence in the trial. Does anyone recall if this theory of Shelley's air being turned off was documented before?
The air consumption or dive time is irrelevant because there were only a couple of minutes where David was out of the water before Christian found Shelley. They began the dive together and he surfaced only a couple of minutes before she was brought up, so he cannot be placed out of the water at the time of her demise. The prosecution also claims that he would have had to see her body when he returned according to his own recollection of his "tour" AND that he would have had to see the fin sticking up in the sand on his way to the boat, though he claimed to see neither. Christian saw both quickly - the fin upon his descent and her body shortly after.
Remember, Swain's psychologist was not a psychiatrist. He was rejected because he was not a medical doctor (which is what a psychiatrist is) and only psychiatrists are accepted as expert witnesses in some jurisdictions.
