Shain was last seen at 3 a.m. Sunday leaving a bar with his uncle, who was also found dead Monday.
From local ABC affiliate WCHS:
Emergency responders converged in the Wolf Pen Road area in Sissonville after reports that a vehicle had been discovered.
David and Shain Gandee last told people they were going four-wheeling in a sport utility vehicle. They were reported missing overnight, according to a news release from the Kanawha County Sheriff's Office.
Shain and David Gandee were last seen at Larry's Bar in Sissonville about 3 a.m. Sunday.
For those uninitiated with the show, Shain was the main comic relief in Buckwild's raucous cast.
Many of the show's segments involving stunts were orchestrated by Gandee.
Like the first episode, where the cast built a pool in the back of a flat bed truck and jumped into it off the roof of the house.
Or the episode were he did this:
He was also given a large amount of screen time, doling out a vast collection of aphorisms and one-liners.
He was portrayed as the "most country" member of the Buckwild cast, spending his off-time between filming as a local garbage man.
For many, Shain was the heart of the show.
Last week, fellow Buckwild star Salwa Amin was arrested for a second time, connected to a drug raid done in February.
According to TMZ, Amin is in custody without bail:
Amin was hauled in today on a bench warrant, which was issued after she allegedly blew off a court date stemming from the first arrest.
Amin was arrested the first time for drug possession following the February raid, which took place at Amin's friend's house. Amin and another friend were accused of transporting oxycodone and heroin to the house in order to sell the stuff.
She was booked on two counts of drug possession with intent to deliver ... felonies.
