Former Survivor: Gabon contestant Dan Kay died "unexpectedly" on New Year's Eve at just 40 years of age.
Police said they were not treating the death as suspicious.
Kay, a lawyer from Massachusetts, lasted 21 days on his 2008 Survivor season before being voted off the island.
The show's longtime host Jeff Probst tweeted his condolences for the "sudden loss", writing, "The Survivor family sends our love to Dan's family."
