Ally Drew and the mystery of the vanished diver

I got an email from my mother yesterday that directed me to an article which described a recent disappearance of a man in Grand Cayman. This is known as one of the premiere diving sites in the whole world, many times listed as more spectacular than the Great Barrier Reef. My mom sent me this article not out of sadness or our shared family interest of diving, but because based on the facts, it was nearly impossible to have added up the way things were presented. She was suspicious, and after reading the article, I decided to lay out what I knew about diving and what I thought were possibilities.
