Guy Wallace, a water taxi driver who was one of the last people to see Ben Smart and Olivia Hope alive, committed suicide after his trial for indecent assault against a teenage girl was set to start. Watson, who has been in prison for almost 25 years, maintains his innocence, claiming he never met Smart or Hope that fateful New Year’s Eve in 1997 at Furneaux Lodge in the Marlborough Sounds and was not the mystery man on the water taxi who invited the friends to sleep aboard his boat.
