Thomas Tonus Lyon was 18 when he vanished from the Sioux Lookout, Ontario area on June 28, 1998. He was with two acquaintances near Iron Bridge and Pelican Lake that day; at some point he disappeared and has not been seen or heard from since.

At the time he was described as 5 feet 9 inches to 5 feet 10 inches tall, 134 to 141 pounds, slender, with short black hair and brown eyes. Distinguishing features include crooked teeth, a 1.5-inch scar on the right side of his neck, and a Motely Crue tattoo on his left forearm.

Very few details about the circumstances of his disappearance have been made public and there have been no reported breakthroughs. Anyone with information is asked to contact the Ontario Provincial Police in Sioux Lookout.
