Tarino Lightbourne who is accused of trying to extort money from the actor following the death of 16-year-old Jett insists medical aid was called too late to help the boy, who had suffered a seizure in the bathroom of the familys Bahamas holiday home on January 2.
Lightbourne said: His pupils were fixed and dilated. He had flakey, dry bloodstains on his mouth, ears and nose.
"This boy was dead. No signs of life. Dead stiff. The veins were collapsed."
According to the defendant, he was offered £9 million by Travoltas lawyer Michael McDermott to dispose of a Refusal of Transport/ Treatment document which the Pulp Fiction star had signed because he and wife Kelly Preston wanted Jett to be flown back to the US for treatment.
Representatives for Travolta have admitted he signed the form, believing it to be standard procedure.
Jett was eventually taken to a local hospital, where he was pronounced dead.
It is claimed that Lightbourne and his co-accused, former Senator Pleasant Bridgewater, demanded £18 million from Travolta and threatened to sell a story claiming the couple intentionally killed their son.
Both defendants deny the charges. The case continues.
