Shain Gandee was found dead in his Ford Bronco truck Monday morning on Wolf Pen Road in Kanawha County, WV, CBS's WTRF-TV affiliate in Wheeling, WV, reported.
The 21-year-old and David Gandee, his 48-year-old uncle, had been reported missing by family members on Sunday.
According to officials, the Buckwild star's body was discovered along with the body of his uncle and a third body -- whose identity has not been released despite family members already having been informed.
Shain and David were allegedly last seen leaving a Sissonville, WV bar at 3AM Sunday morning to go four-wheeling in Shain's vehicle.
Family and friends of the pair spent most of Sunday trying to find them before they eventually called 911, WTRF-TV reported.
