Officials at a Bahamian funeral home have revealed the cause of death of John Travolta and Kelly Preston's son, Jett.

In a press conference in front of the Bahamian funeral home handling Jett's remains on Monday, Keith McSweeney, the funeral director, said that the 16-year-old's cause of death was from "a seizure disorder."

Doctors conducted an autopsy earlier in the day to determine the exact cause of death. He added that, "Police see fit that [there's] no need to detain the body. The body was turned over to me at 2:30 p.m. The family has requested cremation, and that is being done now. May God bless the Travolta family."

Assistant funeral director Glen Campbell told ET that the Travoltas' "lawyer and doctor" will be handing over the remains of Jett to the family. Travolta is expected to fly the remains to Florida on his personal plane tomorrow.
