After months of investigation, Australian police
charged American Gabe Watson on June 20 with murder.
He allegedly drowned wife Tina, 26, on a honeymoon
dive trip aboard Mike Ball’s Spoilsport in 2003 after only
11 days of marriage. The coroner ruled there were suspicious
circumstances, and rejected a claim by Watson’s
attorney that he was denied the presumption of innocence
due to media attention (Australian press covered
the inquest and NBC’s Dateline ran a story this spring).
Watson didn’t go to Australia for the inquest. He was
  videotaped during police interviews, claiming Tina, a
  novice diver, had panicked during a dive to the Yongala
  wreck near Townsville. He said she thrashed around in
  the water, grabbed hold of his mask and pushed it off his
  face. Despite his dive experience, Watson said he decided
  to go for help rather than follow his bride downwards and
  attempt a rescue.  
Police initially believed it was an accident but became
  suspicious when Watson kept changing details of his
  story. They found no pre-existing medical conditions nor
  anything wrong with Tina’s dive gear. After reenacting
  the dive, police believe Watson restrained Tina, turned
  off her air supply until she was dead or close to it, then
  turned it back on and let her sink to the seabed.  
Evidence showed Watson made some moves for financial
  gain before and after the fatal trip. Tina’s father said
  that shortly before the wedding Watson had asked Tina
  to increase her life insurance and make him sole beneficiary
  (she didn’t). Watson had tried to sue his travel insurer
  five days after his wife’s death but discontinued legal
  proceedings in May. In January, the inquest attendees
  saw undercover video footage of him using bolt-cutters to
  remove flowers secured to his wife’s grave in Alabama.
Queensland police are preparing a warrant for
  Watson, the first step in what’s expected to be a long,
  drawn-out extradition battle.
