Police are reporting that Jett was left alone for more than ten hours from when he was last seen heading to his bedroom at the Travolta's vacation townhouse at 6 PM after a day of boating with his family. Jett's nanny, Jeff Kathrein, reportedly found Jett lying on the bathroom floor at 11:30 PM, TMZ reports.
Jett Travolta, who was disabled, was nonverbal and required the use of a baby monitor and a special chime to summon his two male nannies if required.
Kathrein and the Travolta's attorney, Michael McDermott, says that Kathrein went to the bathroom in the time span between 6 PM when Jett left the room and 11:30 PM when his body was discovered so Jett was reportedly not unattended for ten hours.
The teenager is alleged to have possibly had a seizure and struck his head, which could have caused his death. McDermott also reports that Jett was known to sleep for 12 to 16 hours a day so him not being present for a long period of time would not have been unusual.
The official cause of death will be reported by the coroner on Monday."
