Lillie Darlene Miller, 21, vanished after leaving work at Riviera Beach City Hall on December 11, 1981. She worked there as a secretary and left around noon to have lunch with her fiancé, Otis Morgan, at his West Palm Beach apartment. Morgan said they had lunch, but Miller never returned to work and was not seen again.

Miller’s beige 1979 Pontiac Grand Prix was found later that day near her workplace, unlocked and with no sign of foul play. Investigators suspected foul play in her disappearance. Morgan became the primary suspect because of his conduct, a history of violent incidents, and reports placing a man resembling him near a wooded area carrying a shovel the day Miller vanished. Morgan died by suicide six months later on their planned wedding day and left no note; no conclusive evidence tying him to Miller’s disappearance surfaced.

Family members held a memorial service a year after she went missing, and the case remains open. Does anyone have information about Lillie’s movements on December 11, 1981, or about the beige 1979 Pontiac Grand Prix?
