Although I sympathize with the family, how did this ever make it into a court room? It doesn’t sound like there’s any evidence that he did it...
Seems hard to prove but I’m guessing he did it. All the cases I’ve read about that were accidents were quite different. Loved ones, friends and so forth go to great extent to help. They don’t swim away especially if they are an experienced diver. Rescue dive training specifically addresses this kind of incident and his actions are not compatible.
The fact she’s on the bottom is also suspicious. That means she either dumped the air out of her vest or was overweighted. Possibly both. I can see where he turned her air off, she ran out and panicked. Her training would have been to turn to her dive buddy, him, for his alternate air supply. He could refuse that and she would quickly drown. If overweighted it would make it hard to do an emergency ascent.
In the training and dives I’ve been on women tend to bolt to the surface more often than men. The fact that she didn’t makes it more suspect. If she died from an embolism or the bends from a rapid ascent it would be less suspect.
Hard to prove but his behavior is not typical.
One of the news shows had an entire segment on this case only two weeks ago. The parents of the dead woman were interviewed extensively and never once mentioned murder. They used “suspicious” and “inexplicable” instead. I don’t think this is revenge, since the Australian diving authorities were the ones who didn’t believe the guy from day one, and actually did a videotaped reenactment of the incident. Plus, after two years, an eyewitness (diver from another ship) came forward.
The motive seems to have been her life insurance policy, which he wanted her to increase and sign over to him before the wedding. She was so busy with arrangements that she lied and told him she did, when she really didn’t. He didn’t get a penny. Sad for her family, I hope they nail this guy before he runs and hides. As of today, nobody seems to know where he is, not even his lawyer.
