Donnis Marie Redman, called Pinky, was 14 when she and 18-year-old Michael Griffin left San Pedro, California, intending to elope in Las Vegas. They were last seen together in Las Vegas on March 1, 1958. Donnis is described as blonde with blue eyes and was last seen wearing a yellow sweater and brown capri pants.

Several days after they disappeared, Michael’s car — a white 1950 or 1951 Dodge Clipper with twin exhausts and loud mufflers — was found abandoned in Williams, Arizona, more than three hours from where they were last seen and off the direct route from San Pedro to Las Vegas. The Los Angeles County Sheriff’s Department opened an investigation; the case remains open. Unidentified remains recovered in the Southwest over the years have been forensically excluded as matches to Donnis or Michael.

What details do readers remember about the couple, the car, or travel through that stretch of Arizona in 1958 that might shed light on their movements?
