Roger Sexton, who was a contestant on the CBS reality series "Survivor: The Amazon" season 6, died at the age of 76. He is survived by his wife Diane Rodrick, a daughter and two grandchildren.

Sexton died on Oct. 27 due to Lewy Body Dementia and his family confirmed the death Thursday, Deadline reported. The former "Survivor: The Amazon" contestant passed away at his daughter's house in Walla Walla, Washington State.

"Confidence, discipline, and determination to succeed were all vital components to Roger's character, which assisted him in being cast on Season 6 of the reality TV show Survivor in 2002. However, the other more challenging aspects of his character eventually prevailed, leading to his eventual demise, but provided lasting memories of the exacerbating force that was Roger," his obituary stated, as per InTouchWeekly.

The obituary said that Sexton was born on Sept. 26, 1946, in Oakland, California. He graduated in 1964 and served in the Vietnam War from 1966 to 1967. Sexton got married to his then-long-time girlfriend in 1968 after returning from the war.

He had two daughters, Heather and Amy, with his wife. But he lost Heather when she was 16 years old due to pneumonia in 1992.

Aside from the obituary, the official Instagram handle of the show also shared a photo of him and wrote, "We are heartbroken to learn of the passing of a member of our Survivor family, Roger Sexton. Our thoughts go out to his family and friends."

The comments section was filled with condolences. One of the users wrote, "Awwww, I worked on his season sad" while another one added, "Deepest sympathy to his family and friends." A user commented, "Rip Roger!!! From one of the best seasons of survivor."

Sexton filmed the reality show from November to December 2002, and it was aired in 2003. He was introduced on the show as a retired Marine and Viet Nam Veteran. He was the seventh contestant to be eliminated in the first season.
