Tina Watson panicked, her husband contends. When he went to help her, she accidentally knocked off his mask. By the time he fixed his mask, she has sunk out of his reach, his lawyer says. A fellow diver who took an underwater picture captured an image of Tina Watson lying prone on the ocean floor.
The prosecutor, however, claims Watson turned off his wife's air long enough to kill her and then turned it back on, letting her drift to the bottom.
Watson has already served 18 months in an Australian prison for negligent manslaughter, which is essentially an admission that he failed to save his wife's life when she got in trouble.
Alabama is prosecuting the case because it claims that Watson plotted while in the U.S. to kill his wife and collect what he expected to be $130,000 in life and travel insurance.
Watson's lawyer argued in his opening statement that his client did not receive any insurance money for his wife's death, that they were in love and her death was a "tragic accident."
Bloomstom also claimed that Tina Watson was a green diver sent on a dangerous "red flag" dive, that the shop did not have her take an orientation dive, and that she was outfitted with 20 pounds of weights, too heavy for her body.
