TMZ reports that Shain Gandee, a member of the cast of MTV's reality series "Buckwild," was found dead along with two others in a truck in Sissonville, WV.

The Kanawha County Sheriff's Department issued a statement Monday morning saying that they reported the reality star as missing, later confirming that Gandee, 21, along with two other people, was located in a vehicle on Wolf Pen Road.

One of the other bodies was identified as Gandee's 48-year-old uncle, David Gandee. The identity of the third body has not been released.

Sources claim that there is evidence that the three may have died of carbon monoxide poisoning.

A source says that the Gandees told family members that they were going four-wheeling, but did not specify a location. They were last seen leaving the parking lot of a bar Sunday morning.

MTV released the following statement:

"We are shocked and saddened by the terrible news about Shain Gandee, and those involved in this tragic incident. We are waiting for more information but at this time, our main concern is for the Gandee family and their friends. Our thoughts and prayers are with them. Shain had a magnetic personality, with a passion for life that touched everyone he met and we will miss him dearly.”
