Gail Marie Dahl, 22, of Simi Valley, California, was last seen on August 2, 1980, and remains missing. She is described as a white female with blonde hair, green eyes, and a horizontal scar on her left calf; at the time she was 6 feet 0 inches tall and about 135 pounds. She may have used the name Gail Gardner.

A key detail: her car was recovered 12 days later, on August 14, in Imperial County, California, roughly 10 miles northwest of Yuma, Arizona. Apart from the vehicle, no confirmed trace of her has been reported and few details about her last movements were ever established. The Simi Valley Police Department continues to seek information in the cold case.

If anyone knew Gail, saw her car in August 1980, or has information that could help investigators, please contact the Simi Valley Police Department.
