In 1999, 43-year-old David Swain, the owner of Ocean
State Scuba in Jamestown, RI, and his 46-year-old wife
of nearly seven years, Shelley Tyre, chartered a sailboat
in the British Virgin Islands with friends Christian and
Bernice Thwaites and their son. The last day they were to
dive, they moored off Cooper’s Island to dive two tugboat
wrecks.
The couples had agreed that two adults would remain
on the boat to watch the Thwaites’ boy, so Tyre and Swain
went into the water. Swain returned to the boat alone 35
minutes later, saying he was chilled. Christian Thwaites
dropped into the water for his dive.
Moments later Thwaites spotted one of Shelley Tyre’s
yellow swim fins and looked for Tyre, figuring she would
be grateful that he had found her fin. Instead, he found
her lying on her back on the sandy bottom with her eyes
and mouth open. Thwaites took Tyre to the surface,
where he tried to perform CPR. Swain, who had been
an emergency medical technician, helped lift his wife
aboard, but did not try to resuscitate her. She was dead.
James Philip Brown, who runs Aquaventure in Tortola,
thought the death was suspicious. Tyre and the Thwaites
had visited his shop to rent gear and discuss where to
dive. A day after Tyre died, Brown dived the wrecks looking
for something that might explain the death. Brown
found one of Tyre’s fins embedded toe first in three inches
of sand. He found her snorkel, sans mouthpiece, and
her mask. On one side of the mask, the strap hung loose
off its anchoring pin.
Brown locked Tyre’s scuba gear in his office to await inspection by Tortola police. Two days later, Swain told
him that he could get rid of the equipment, give it to a
local diver or use it in the rental business. Brown refused.
Swain fretted that the medical examiner was taking a long
time to do an autopsy and asked if he knew anyone who
might “expedite the process.” Swain said that “the medical
examiner might not know about diving accidents,”
and he wanted to talk to him before the autopsy. Swain’s
remarks seemed irregular to Brown, enough for him to
approach Tortola police. But zno charges were brought.

Shelley Tyre’s parents asked Swain
for an explanation of the death, but
did not find him forthcoming. As
more information came to light, and
Swain continued to stonewall, they
brought a wrongful death suit against
him, which was heard over nine days
in February 2006.
A violent struggle
During the trial, Bill Oliver, a mechanical engineer
who designs diving equipment and is product manager
for Sherwood, presented videos of tests he conducted. He
showed how Shelley Tyre’s fin would have simply sunk,
heel first, under normal conditions, and how the strap
of her mask could have pulled free if it had been yanked
from behind. When Brown found Tyre’s fin, the heel
strap was still fastened tight. Oliver testified that only a
strong “external force” could have pulled the fin off.
Dr. Thomas Neuman, a diving medicine specialist reviewed Tyre’s medical records, and said the five- foot,
one-inch woman weighed 120 pounds and was in good
health. She had logged at least 352 dives, and had no
reason to panic. Her tank was two-thirds full when it was
found and the dive site was a “benign” sand location.
The chief medical examiner of Miami/Dade County,
Bruce Hyma, testified that evidence suggested a “violent
struggle with another individual.” The pin holding one
side of the mask strap in place was missing, indicating it
had probably been ripped from the mask frame. Hyma, a
diver for 36 years, said no medical condition would have
interrupted Tyre’s normal breathing. With her experience
she could have effectuated a self-rescue if she had
the opportunity. “Her air supply was shut off,” he said,
and he called it a “homicidal drowning.”
Underwater forensic investigator Craig Jenni concluded
that Swain had attacked his wife in 80 feet of
water. Had Tyre encountered an emergency other than
an attack, she would have dropped her weight belt to the
surface as fast as possible. But Tyre was found with her
weight belt still on. Her primary and octopus regulatory
were working perfectly.
Based on air still in Tyre’s tank when it was found,
Jenni determined Tyre was underwater for about eight
minutes before she stopped breathing. Divers normally
swim about one foot per second while underwater, an
important calculation considering what Swain said during his deposition: after a five-minute descent to the wrecks
together, he set off alone and made one revolution
around one of the sunken boats.
After considering the size of the wreck and Swain’s
own mapping of his swim, Jenni figured it would have
taken Swain about three more minutes to get back to
where he had left Tyre. “At that precise time, Shelley
was no longer breathing,” said Jenni, and Swain was in
her vicinity. Even if she were already unconscious, Swain
would have had to see her, Jenni said. But he came up
alone. “The only conclusion,” said Jenni, “is David Swain
attacked Shelley Tyre.”
After the fact
Keith Royle, a Tortola dive operator, responded to
the Mayday call. When he got to the sailboat, he jumped
aboard and offered to perform CPR, but was told it
wouldn’t be necessary because Tyre was dead. He thought
it unusual since he was taught “you do CPR until someone
more qualified takes over.”
Three hours after Tyre’s death, Swain gave a written
statement to the Tortola police, saying his wife had swam
off and left him by the wrecks. When he could not see
her, he went looking for her. However, in depositions
taken in 2003 and 2004, Swain said they dived together to
the tugboats. Swain said it was common for them to split
up — she counted fish and he took photographs. But, he then contradicted his statement to the police, saying he
swam around one of the wrecks before moving toward a
reef in shallower water. At some point, he said, he looked
back and saw Tyre, the last time he saw her alive.
When asked where was the dive computer he wore
that day, which would have registered how long he was
under the water and what depths he reached, Swain said.
“I haven’t a clue.” He said he also could not remember
where the photographs were that he took during the dive.
Had he drawn any conclusions, asked Olenn, about how
his wife died? “Nope,” said Swain.
Swain’s testimony was on videotape. Swain did not testify
on his behalf and chose not to be represented by his
own counsel during the trial.
Sex and Money
Why would a dive shop owner murder his wife and
dive buddy? Before the death, Mary Grace Basler testified
that, she had rebuffed Swain’s advances, telling him
she wasn’t interested because he was married, though he
overnighted at her home once. Two weeks after Tyre died,
Basler met Swain at a restaurant and in two months they
were lovers, she said.
While a prenuptial agreement prevented Swain from
receiving anything from Tyre if they divorced, after the
death Swain collected $570,000 from life insurance policies
and Tyre’s investments. By February 2003, he was in
debt from taking extensive trips to the Caribbean and
other cities. He currently faces debts of $189,000.
Swain chose to defend himself outside the courthouse.
He said, “This is a tragic accident that is a personal matter
between me and the Tyres” — his former in-laws. “I didn’t do it. . . . I feel for the Tyres. . . They have the pain to deal
with. I have pain to deal with too. But the thought that
we are going to work out this pain by going through this
is absurd . . . This issue of money . . . is not something I
want to be a part of.”
Tyre’s lawyer said it was not about money, “it’s about
justice . . .Tortola authorities won’t do anything, and
Rhode Island authorities can’t, and so it’s up to [the jury]
to see that justice gets done.”
The Verdict
During closing arguments, the jury heard Tyre’s attorney
tell how he believed Swain had killed his wife. Using
a videotaped demonstration filmed underwater where
one diver attacks another, he described how Swain had
climbed onto Shelley Tyre’s tank, ripped off her face
mask, shut off her air supply, and held her down on the
sandy bottom.
The eight member jury found Swain guilty and
awarded Tyre’s parents $3,534,943 for compensatory and
punitive damages. The standard of proof for a civil jury
is whether “the “preponderance of evidence” leads them
to believe that the alleged crime occurred. Jury foreman
Robert Capello said the jurors were not convinced the
attack happened as outlined, but “other than human
intervention, how else could she have died? And who else
was in the vicinity when it happened other than Swain.”
After the verdict, Swain said, “I would welcome a criminal
trial.” At least then “all evidence gets evaluated” and
not just pieces. Swain is considering an appeal and has
sued Shelley Tyre’s parents for defamation.
