Donnis Marie Redman was 14 when she and her 18-year-old boyfriend, Michael Griffin, left San Pedro, California on March 1, 1958, intending to elope to Las Vegas. Both disappeared after that trip and neither has been heard from since. Griffin’s white Dodge Clipper was found abandoned several days later in Williams, Arizona, but searches turned up no trace of Donnis or Griffin.

At the time Donnis vanished she was wearing a yellow sweater and brown capri pants. Investigators and both families have revisited the case over the years, and some have suspected foul play, but no substantial evidence has been reported and the fate of Donnis and Michael remains unknown.

If anyone has memories of Donnis, Michael, the Dodge Clipper, or travel along the Las Vegas–Arizona route in early March 1958, please share what can help this cold case move forward.
