Secret police videos have captured the alleged extortionists in the John Travolta case in deep conflict haggling over money- we're told they finally agreed to $15 mil.

We're also told lawyers for Bridgewater and Lightbourne will make a motion today to suppress the videos, on grounds they were illegally recorded.

John Travolta has testified about the moment he was told his 16-year-old son had passed away.

Travolta told the court this afternoon that sometime after he and his wife Kelly Preston arrived at the hospital, they were told Jett was "not alive."

The first witness in the John Travolta extortion case took the stand today and testified that John initially wanted to take his son Jett to an airport instead of a local hospital.

John thought it would take just as long to put Jett on a plane to Florida - where he could get better care than at a Bahamian hospital.

John Travolta made his first public statement acknowledging Jett had autism.

Travolta told the jury in the Bahamas extortion case that Jett was autistic and suffered seizures every 5 to 10 days. Saying, "He was autistic. He suffered from a seizure disorder."

John Travolta just described to the jury in the extortion trial how he desperately tried to save his son's life.

Travolta testified his nanny woke him up and told him his son was unconscious in the bathroom. Travolta says he performed CPR on Jett, ultimately to no avail.

John Travolta just walked into court in the Bahamas with wife Kelly Preston - where he'll testify in the extortion over their son's death.

Travolta will testify about his interaction with the paramedic/defendant while they were trying to save his son, and the alleged extortion demand.

TMZ has confirmed John Travolta will testify next week at the extortion trial involving the death of his son, Jett.

We're told Travolta and wife Kelly Preston are outraged by the alleged extortion plot which authorities say was concocted shortly after Jett's death.
