UPDATE: Kanawha County Sheriff's Department Corporal Brian Humphreys confirmed to MTV News that the bodies of Shain Gandee, 21 and his uncle, David Gandee, 48, were discovered on Monday (April 1) morning, along with that of a third, as yet unidentified person.

At press time, Humphreys said that there is "no reason" to believe that foul play was a factor in their deaths. He could not confirm reports that the vehicle was found submerged in water or overturned. Corporal Humphreys described the scene as being very remote and inaccessible by police vehicles, with investigators forced to use ATV's to gain access to the site. "The medical examiner's office will determine the cause of death and they will release that information," he added. Humphreys also noted that there did not appear to be signs of any other vehicles in the area.

A spokesperson for the West Virginia Office of the Chief Medical Examiner could not be reached for comment at press time.
