Sexton competed on “Survivor: The Amazon”, in 2002. As a retired Marine and Viet Nam Veteran, Sexton had a gruff and commanding demeanor that was divisive among some of his fellow contestants but also lead to early success for his tribe.

After becoming the de facto leader of his Tambaqui tribe, Sexton wound up getting voted off when the tribes merged and was the seventh person to get kicked off the game, after 21 days.
