Kanawha County Commissioner Kent Carper tells PEOPLE that the family notified authorities on Sunday that they were missing since Saturday. A very intense search was done, concluding Monday morning, he adds, revealing MTV had been filming all weekend with Shain.
They had told people they were going four-wheeling in an SUV and were last seen at Larry's Bar in Sissonville, W.Va., WCHS TV reports.
According to his bio on the stunt program's website, Shain, nicknamed "Gandee Candy," was "sociable and loyal." He was his high school's prom king, and had done every job from coal mining to being a garbage man.
"Says the bio, "He loves mudding, hunting and four-wheeling, but most of all he loves his parents, who live three doors down."
