Lloyd Melvin Thomas, 88, vanished in the summer of 1988 while traveling by Greyhound from Covington, Kentucky, to San Antonio, Texas to visit his son. He was last seen July 24 at the Madison Station in Covington boarding a bus bound for San Antonio with a brown overnight suitcase. He wore a tan plaid jacket, a bluish-gray plaid shirt, gray slacks, eyeglasses and a watch.

Family had noticed increasing forgetfulness before the trip, though he had no formal dementia diagnosis. The bus route included stops in Louisville, Kentucky; Nashville, Tennessee; and Dallas, Texas, but no witnesses have come forward to confirm whether he disembarked at any scheduled stop. Covington police were notified three days after he was last seen and list the case as endangered missing and open.

Who knew Lloyd or traveled that Greyhound route in July 1988 and might have seen him?
