Details of Disappearance

Valdez-Blackburn was last seen in Cheyenne, Wyoming on November 21, 1983. She was a vehicle mechanic assigned to the 90th Transportation Squadron at the F.E. Warren Air Force Base. Valdez-Blackburn was seen loading up her yellow Dodge Ram pickup truck, which had the Colorado license plate number 4250JX, and she said she was leaving. She is believed to have been on the way to visit a friend in Denver, Colorado.

She never returned home and was officially classified as a deserter on December 21, a month later. She is now listed as a missing person, however, as decades have passed without any contact and the Air Force does not know whether her disappearance was voluntary or not.

The circumstances of her disappearance are unclear.
