John Travolta testified Wednesday that Bahamas paramedic Tarino Lightbourne threatened to sell stories to the media suggesting the actor was at fault in the death of his 16-year-old son. Travolta said the paramedic, who is now on trial for extortion, demanded $25 million. If Travolta refused, Lightbourne said he would release a consent document that the actor initially signed refusing to have his son Jett sent to a local hospital. (The document cleared Lightbourne of any liability.) "They were stories that would imply that the death of my son was intentional and I was culpable in some way," Travolta said.
