TORTOLA, British Virgin Islands - A jury convicted a Rhode Island man of murder Tuesday in the drowning of his wife during a 1999 scuba-diving trip in the British Virgin Islands.

A judge expects to sentence David Swain on Nov. 4. He faces life in prison and would be sent to a Tortola prison where he has been held for about two years. Swain did not react when the verdict was read, although the parents of victim Shelley Tyre gasped at that moment.

After obtaining permission from the judge, Richard Tyre walked to the witness box and clutched a microphone.

"We're old, we're in our 80s, and when Shelley was killed, our life pretty much ended," he said in a broken voice. He then left the courtroom.

Defense attorney Timothy Bradl, of the Boston-based firm Denner Pellegrino, said they would appeal the case to the Eastern Caribbean Court.

Prosecutors accused Swain of killing his wife, Shelley Tyre, so he could pursue a romance with a Rhode Island chiropractor as well as gain his wife's inheritance estimated at $630,000 and save his now-shuttered dive shop. The drowning was initially ruled an accident.

, but authorities in the British Virgin Islands charged Swain with murder after a 2006 civil trial in Rhode Island found him responsible for his wife's death. That jury awarded Tyre's family $3.5 million, but Swain filed for bankruptcy and has not paid the sum.

Swain was extradited to the British Virgin Islands the following year and had been jailed since.

Defense attorneys maintained the poorly done autopsy report could not rule out medical reasons for Tyre's death, including the possibility that she suffered a heart attack or stroke during what they say was an accidental drowning.

The trial, which began nearly three weeks ago, was postponed last year after defense lawyers said they had trouble finding experts because of financial constrictions.
