He told the jury he signed the form and the ambulance sped away, but on the way the plan was changed and Jett was taken to the island's Rand Memorial hospital instead of the airport.

Jett was pronounced dead on arrival.

'Mr. Lightbourne told me Mr. Travolta wanted his son taken to the airport instead of Rand Memorial hospital. He then asked me to witness a refusal for medical attention form which he showed me. I signed that document,' said Wells while speaking about the scenes at the Travolta family home on Jan 2 following Jett's fatal seizure.

Lightbourne and his attorney Pleasant Bridgewater are jointly accused of attempting to extort and conspiring to extort by means of threats, charges they both deny.

Travolta, who is listed as one of 14 prosecution witnesses, will testify at the trial.
