Jett Travolta, the 16-year-old son of actor John Travolta was found dead, in the family’s home in the Bahamas. Travolta has said that he and his wife, actress Kelly Preston, are “heartbroken” over the death of their son. Both of them and their daughter, Ella, were present at the home when Jett died.

Jett had a developmental disability that his parents have linked to Kawasaki disease, an inflammatory disorder of the artery walls that most commonly occurs in young children and can lead to heart disease. In 2001, John Travolta revealed in a TV interview that his son had a near brush with death related to the condition. He went on to speak about how it changed the actor’s living practices. “I was obsessive about cleaning – his space being clean, so we constantly had the carpets cleaned. And I think, between him, the fumes and walking around, maybe picking up pieces or something, he got what is rarely a thing to deal with, but its Kawasaki syndrome.”

Dedicated Scientologists, Preston and Travolta credited a detoxification program from the writings of Scientology founder L. Ron Hubbard with helping improve their son’s health. In past times Scientology has stirred controversy when clashing with the world of medicine – particularly with the world of psychology.

An autopsy on Jett Travolta will be performed Monday, family attorney Michael Ossi said last week. The boy hit his head after the seizure, but the exact cause of death is not known. He is scheduled to be buried in Florida. John Travolta gained fame in the 1970s, starring in Saturday Night Fever and Grease. His career got a boost in 1994 with his second Best Actor Oscar nomination, for his role in Pulp Fiction. Preston has numerous TV and movie credits, including a supporting role in 1996’s Jerry Maguire.
