When a newlywed couple go diving on the Great Barrier Reef for their honeymoon, no one would have believed that just one of them would return to the surface alive. Dennis Murphy reports on how investigators attempt to fill in the pieces of this mysterious death and try uncover whether it was an accident or something worse.
Mystery in the Deep Blue Sea is two-hour Dateline report that airs Friday, March 11, at 9pm/8c.


I knew Tina from high school, when she lived in Mandeville, LA. She was very outgoing and always smiling. What has happened to her was tragic. It is disturbing that this guy is getting away with murder, literally. I hope he gets his day in court and goes away for a long time.
Thank you for airing this story. I am sure it is important to Tina's family, as it is to her friends.
Just when I thought I couldn't be anymore disgusted by Gabe Watson, in walks his defense attorney. What a dispicable person.
Two things puzzle me. The witness cared enough to join in the resuscitation effort, but I'm not sure why he didn't intervene. He said he saw a woman in a man's bear hold, saw the man go rapidly to the surface, saw the woman panicked, waving her arms, and settling to the bottom, and finally saw the rescuer who brought her to the surface. But the rescuer himself said he saw a woman lying on the bottom and thought she was watching fish; it wasn't until his second look that he noticed no bubbles. So she'd been lying there a while. Why didn't the first witness, who says he saw a struggle, help?
The second thing seems so minor and for some reason bothers me in a major way. When Gabe Watson took the flowers from the grave, it doesn't appear that he replaced them with his own. That seems to me not just an angry lashing out at the family, as the judge noted, but an angry lashing out at the dead bride. To stuff any flowers on her grave in the trash makes quite a statement.
Very interesting presentation.
@readresp,
I do agree with you 100%!You're totally right.What a weird case that is!Or,should I say,what a "weirdo" Gabe is!Hes mosdef a psychopath,no doubt abt it.
Whats disturb me the most at this point(now),is that if he ever face a jury in Alabama,a lots of evidence we saw on Dateline wont be admissible in court!The grave "stuff" wont be admissible IMO,and God knows,it say a ton abt his character,even more that we can put in words.mean
And what you said abt the doctor(witness!)not helping is also kind of "weird".By weird I that I dont understand.Something is missing here.
So many questions,SO MANY!!!
I know its a circumstantials case,but I'm really disappointed with the Australian justice system.But the US justice has his own problems...But I just meant in that case,there were some...loose ends(to say the least!)
Anyway,I just hope he pays for what he did.He did a terrible thing.Well...we'll see!
