Michael James DeMaria, 28, vanished from Manhattan on October 14, 1976 after being seen leaving his apartment building. He was described as White, 5 feet 11 inches, about 180 pounds, with brown hair and brown eyes, dimples and scars on his stomach. When last seen he wore a blue button-down shirt, blue shoes and a blue sapphire ring.

Authorities say there was no known reason for him to leave voluntarily, and suspicions of foul play have been noted. The New York City Police Department’s Missing Persons Squad has kept the file open and the case is entered in national databases under NamUs MP19729, but investigators have found very few leads and the investigation has grown cold.

What details do readers remember about Manhattan in October 1976, or does anyone have information that could help locate Michael?
