Yes looking at her she did not look that fit and the fear and shock could have caused her to pass out or have a heart problem. As you said in the evacuation it is quite possible she vanished in seconds under the water.
i agree in warm waters like that with numerous predators they will be unlikely to find a body which will further stoke the conspiracy theory.
Sharks are amazing creatures and fantastic to dive with but terrible scavengers with prey they do not regard as a threat.
i have dived with Oceanic white tips, Tiger, Hammerheads, reef sharks, blue, Angel Sharks and only ever felt threatened by the oceanic white tip
and that one I did feel like a potential meal
