A man in Cocke County was killed after an accident when a mower he was on flipped upside down into a creek bank, pinning him underneath the water. The homeowner told deputies she had hired 64-year-old Billy Hugh Masoner on Wednesday to mow at her residence on Upward Road in Parrottsville. Masoner was mowing when it slid off the bank, flipping upside down. He was wearing a seatbelt, so he was pulled with the mower into the creek. Deputies said Masoner’s head had been pinned underwater for several minutes before deputies arrived.
