After performing an autopsy, doctors have issued a death certificate saying Jett Travolta's body showed no signs of head trauma on his body and his death was due to a seizure attack.

Keith McSweeney, Director of the funeral home that handled the body of the Travoltas 16-year old son says, Jett's parents will be returning to the United States with his ashes on Tuesday.

With a history of seizures, Jett Travolta was found unconscious in his bathroom Friday at the family's vacation home on the Grand Bahama Island . Despite, police reports that Jett had hit his head on the bath-tub, Glen Campbell, Assistant Director at the funeral home, told the media his body was in 'great condition'.

Late Monday, in what turned out to be an unexplainable ruse, a black hearse travelling from the funeral home to the airport, indicated that the Travoltas were taking Jett's remains to their home in Ocala , Florida . As two white jets waited, police in dress uniforms blocked access to the tarmac, however, it turned out to be a decoy.

Citing Travola's lawyers, USmagazine reports that Travolta gave his son CPR, in an effort to revive him, and it is possible Jett died in his arms before an emergency medical technician took over.

It seems aged two, Jett was diagnosed with Kawasaki Syndrome, an illness Kelly Preston, 46, blames on household cleaners and fertilizers. Talking to People magazine, Preston told them that a detoxification programme based on teachings of the Church of Scientology , did much to improve his health.

McDermott, one of the lawyers for the Travoltas saysm the police statement that no one had seen Jett since Thursday and he was found unconscious by the caretaker late Friday morning, left people with the wrong impression that Jett had been left unsupervised. The truth is, both nannies were with Jett throughout the evening and the teen could not have lain unconscious for very long.

Expressing their grief, John Travolta and his wife, actress Kelly Preston releasing a statement on Sunday said: 'Jett was the most wonderful son that two parents could ever ask for and lit up the lives of everyone he encountered. We are heartbroken that our time with him was so brief. We will cherish the time that we had with him for the rest of our lives.'

With the death of their son Jett, the Travoltas are consoled by Ella Bleu, their 8-year-old daughter.
