William Jay Sharphead, known as Billy Jay, was 35 when he vanished from the Enoch Cree Nation just west of Edmonton in early September 2003. He was last seen leaving his home and is believed to have gotten into a vehicle; who was in that vehicle and where they went remain unknown. He was known to frequent areas between Enoch Cree Nation, the Stoney Nakoda Nation at Morley, and the city of Edmonton.

At the time of his disappearance Billy Jay was described as First Nations, 5 feet 7 inches to 5 feet 8 inches, about 141 pounds, with shoulder-length straight black hair, brown eyes, and tattoos including a skull on his upper shoulder and a Superman logo on his upper right arm; he had scars on his nose and head and wore a black-and-white track jacket and matching pants when last seen. His family believes foul play may be involved and has mounted repeated searches over the years, including organized community searches, combing cutlines and camping spots, searches at a nearby pond, and work with the Search and Rescue Dog Association of Alberta. An age-progression sketch was released in 2018, and the family held a large historical search in September 2022 after 19 years of searching.

The investigation remains open. If anyone knew William Jay, saw him in 2003, or has information about a vehicle or movements in the Enoch, Morley, or Edmonton areas that autumn, please come forward.
