Minish was last seen after she left her job at a Kentucky Fried Chicken restaurant on Wrightsboro Road in Augusta, Georgia on March 17, 1987. She has never been heard from again. Her 1985 Chrystler LeBaron was found a few days later at the Wrightsboro Road exit of the Bobby Jones Expressway. One of its tires was flat, the door had been pried open, and the steering column was smashed, possibly by someone attempting to hot-wire the car. There was no sign of Minish at the scene.

It's uncharacteristic of Minish to leave without warning, and she never picked up her last paycheck or sent anyone to get it for her. She also left all her belongings behind. Minish resided in Evans, Georgia in 1987. Foul play is suspected in her case; she's presumed to have been the victim of a homicide.
