According to the death certificate issued for Jett Travolta, the teenager died of a seizure and not by hitting his head on a bathtub, as was previously suspected. “There was no sign of head trauma,” a mortician at the Restview Memorial Mortuary in the Bahamas told E! News. “The body was in good condition.” The funeral service is expected to be held tomorrow in Ocala, Fla., where the family has a home. Jett’s body is being cremated, with his remains being given to the family tomorrow.
