Death of Tina Watson
While scuba diving at the site of the SS Yongala, a passenger ship that sank in 1911 in the main southern shipping channel to the Australian port of Townsville, Tina Watson either lost consciousness or died and then sank  to the sea floor below. Tina's death of accidental drowning was not a criminal investigation in itself in Australia. It was a coronial enquiry. Mr Watson gave evidence to the Coronial Inquiry through his lawyers. He returned to Australia voluntarily and spoke to investigators on a number of occasions. Some of these interviews are available on the Internet. At trial, prosecutors said that Mr Watson had made a mistake in not trying to rescue his wife. They said that mistake was the same as manslaughter (see: Court of Appeal Judgement). Tina's father  that, immediately before their wedding, Gabe had asked Tina to increase her life insurance policy to the maximum possible and make him the sole beneficiary.
