JOHN Travolta has travelled to the Bahamas and is prepared to be the first witness Tuesday in an extortion case linked to his 16-year-old sons death, a source told PEOPLE. John Travoltas son died of a seizure in January 2009 at the age of 16. The actor is staying at an exclusive gated community west of Nassau, the source said. This is believed to be Travoltas first visit to the Bahamas since Jett Travolta died last January after suffering a seizure at the actors vacation home on the island of Grand Bahama. Paramedic Tarino Lightbourn and his attorney, former Bahamian Senator Pleasant Bridgewater, are accused of conspiring to extort $25m from Travolta for a document relating to Jetts treatment. The pair have pleaded not guilty and are out on bond. Supreme Court Judge Anita Allen swore in the six-woman, three-man jury Monday, with opening statements slated to begin Tuesday morning. People Travolta, who has spent much of the past year in seclusion, now heads the 14-member witness list, was not among the four witnesses present in court during jury selection. But he is expected to testify - and likely will have to recount the painful memories of Jetts death - since he filed the extortion complaint. If the prosecution doesnt call him, we will, Mary Bain, a lawyer representing Lightbourn, told PEOPLE. Of course, hes a key witness.
