John Travolta John Travolta

The paramedic charged with trying to extort John Travolta over the death of his son was threatening to reveal a medical document irrelevant to 16-year-old Jett's death, according to Bahamian officials.

Tarino Lightbourn has been in custody since his arrest on Jan. 23, and is charged with conspiracy to commit extortion and attempted extortion. His attorney is charged with two counts of extortion.

Lightbourn attempted to sell a one-page document that Travolta signed when Lightbourn was treating Jett, Bahamian police told People. Travolta's son died of a seizure this month at his family's vacation home on Grand Bahama.

The document, called a "refusal to transport," did not apply in the Travolta case, Senior Assistant Commissioner of Police Marvin Dames said.

"It did not apply because he was very ill, and so, the only alternative would be to take him to the hospital. Refusal to transport documents are for cases involving minor injuries, Dames said. "If your injuries are minor and you don't want to be transported, the ambulance driver would produce that form. It waives responsibility on the part of the hospital."

Dames said the Travoltas did everything they could to save their son.

"We were satisfied from all our investigations that the Travolta family and those who rendered aid ... did all that was humanly possible to revive Jett," Dames says.  

"There's no evidence to support that there was any effort to avoid medical treatment," he adds. "Lightbourn said that himself in several interviews."

Dames told People the extortion attempt occurred nearly two weeks ago, when Lightbourn's attorney, former Bahamian Sen. Pleasant Bridgewater, called a Travolta attorney and said Lightbourn wanted to sell the document. Travolta then complained to Bahamian police.

"The complaint states the request was for $25 million," Dames says. "At the time, she represented the young man. She would have made the request."

Bridgewater has said her actions were misinterpreted and that she is innocent of any wrongdoing.

Dames said investigators haven't located the document, and can't verify its authenticity.
