Wilber Elmer Mcmillan, 66, disappeared from his Trenton, Michigan home in the pre-dawn hours of March 2, 1997 — the night of his and his wife’s 40th wedding anniversary. He was last seen sometime between midnight and 5 a.m. and never returned.

Friends and family say retirement hit him hard after leaving Great Lakes Steel in 1994; he regretted stopping work and struggled with long winter months and depression. On the morning he vanished he wore blue jeans, a blue sweatshirt, a burgundy jacket, white walking shoes and a black-and-white baseball cap. He had his wallet with $70 and his car and house keys, but left his reading glasses at home.

The Trenton Police Department investigated but the case grew cold and no significant leads have emerged. Does anyone remember Wilber or his movements in Trenton around March 2, 1997?
