Jetttravolta More details have emerged on how John Travolta‘s son, Jett Travolta, died.

And it’s even sadder than you can imagine.

TMZ spoke with John Travolta’s lawyer and close friend Michael McDermott and family attorney Michael Ossi, who are with the actor in the Bahamas.

They say Jett’s fatal injury was probably the result of hitting his head on the bathtub, toilet seat or both. The lawyers say the suggestion that Jett went undiscovered for hours is "absolutely false," TMZ reports.

"Police have said the last time anyone saw Jett was when he went to the bathroom on January 1. His body was discovered by nanny Jeff Kathrein the next day at 10 AM," TMZ reports. "In fact, McDermott and Ossi say it appears Jett went back and forth to his room and the fatal injury occurred ‘very shortly’ before Jett was found on the bathroom floor."

McDermott and Ossi say that two nannies were along for the trip and that one of them, Kathrein, was by Jett’s side "24/7."

It is still unclear whether Jett fell to the floor as a result of a seizure or he had a seizure after falling or slipping. An autopsy will be conducted Monday to determine the cause of death.

TMZ, quoting McDermott, says that a hotel manager was first on the scene with Kathrein and that the two of them administered CPR. John Travolta came in and took over the CPR for a "substantial period of time" until emergency medical technicians arrived and took over.
