Kenneth Kay, known as Lenny, was 15 when he vanished from Quinton, Saskatchewan. He was last seen on May 2, 1972, at the old schoolhouse on Kawacatoose First Nation during Treaty Day, where family members recall him leaning against a wall and declining to ride to town with them. The family reported him missing to the Punnichy RCMP on May 18, 1972.

At the time he disappeared Kenneth was described as slender, with brown hair and brown eyes, wearing a red shirt, a cardigan sweater, light blue trousers and black cowboy boots. The RCMP lists his case as open and active. The family believes he was murdered the night he went missing and has asked for repeated searches of the reserve; a search in 1988 produced no evidence. Authorities say they have received tips indicating the disappearance may have been suspicious but have found no evidence to substantiate those leads.

The family remembers Kenneth as loving and funny and says the uncertainty has been devastating. Anyone with information about Kenneth Kay or his movements in early May 1972 is asked to come forward.
