On November 12th 1966, Kenneth Duncan of Blue Creek and four other men were digging a grave for his father-in-law in Koontz Cemetery near Clendenin, West Virginia. He claimed to see a man-like figure that flew out from some nearby trees and glided low over their heads.
The other men did not see the creature before it flew away but Kenneth said that the brown creature lifted off beyond the trees and it was no bird, it was a humanoid. "It was gliding through the trees and was in sight for about a minute" said Kenneth. He was baffled. It didn't look like any kind of bird but seemed to be a man with wings.
This is said to be one of the first sightings of the Mothman. The men only discussed the sighting with a few friends and it would have been forgotten if others didn't also start claiming to see the winged man. It was the Scarberry and Mallette's Mothman sighting that caused Kenneth Duncan to report his encounter.
