The more I think about this situation the more puzzling it is to me.
There are very few things I can think of where the body wouldn't end up on the surface and that doesn't appear to be the case.
You can have a heart attack and die instantly (my father for example) but in many cases it's not that fast. A newer guy well known on a local board was diving (with a buddy) on a shallower local dive and wasn't feeling good and ended the dive. He was having a heart attack.
He was able to talk on the surface and Lynne happened to be on the surface and was with him as he died (a minute or so later).
Panic due to excessive CO2 due to exertion doesn't kill you either but some freak combination where you gulp water and end up drowning would of course.
Ox tox couldn't really be a factor here.
Most any condition that gave a little warning even if unconsciousness soon followed would allow enough time to inflate the drysuit or wing and you would end up on the surface even if you were then unconscious.
Breath holding (not likely at all in this case) is a major problem mainly during the last few feet in which case you would end up on the surface.
I don't think entanglement is an issue.
It's hard to imagine something that wasn't an issue when she was last seen becoming an issue seconds later.
A massive heart attack brought on prematurely due to overexertion would fit the circumstances but I'm assuming there was no medical history to suggest that. Since something happened, I guess that's about as likely as any other scenario.
It's hard to imagine that something happened and that it prevented her from reaching the surface but those do seem to be the facts.
There were 4 other divers on that boat. It would be instructive to hear from others who were there and who may have had longer dives and could describe more thoroughly the conditions over the whole site.
