I didn't see the show, and don't know a lot about the case, but nothing I have seen shows any sort of motive for killing his wife -- and I gather that these families are well enough off that $130k in life insurance proceeds, even if it was payable, wouldn't have changed his life a lot.
I think that it is quite possible that (1) something happened to the wife on the dive -- maybe she panicked, or sank too fast, or swallowed water, or whatever out of the ordinary and dangerous; (2) husband then panicked (which a manly Southern man just does NOT do) and did not or could not help her, and (3) then tried to lie his way out of or minimize his own responsibility/blame.
It was a sad situation.
Finally, I wonder why in the world a novice diver would even be allowed to dive at the Yongala. When I dove there, the current wasn't bad, but there are many times that it is just ripping. It ain't like slow drift dives at Cozumel.
