While Jett Travolta's heartbroken parents, John Travolta and Kelly Preston, struggle to come to terms with their loss, pathologists in the Bahamas are conducting an autopsy today to find out the exact cause of the teenager's death.

Jett, 16, died on Friday after suffering a seizure while on vacation with his family in the Bahamas, according to Travolta attorney Michael Ossi. He was taken by ambulance to a hospital and pronounced dead on arrival.

Once the autopsy is completed, the results will be given to Jett's grieving parents — who can then decide whether to make them public.

In a statement on John's Web site, travolta.com, he and Kelly called Jett "the most wonderful son that two parents could ever ask for.... We are heartbroken that our time with him was so brief."
