Colleen Kay Burgess, 25, vanished from Englewood, Colorado in late summer 1974 after finishing a shift at the Frito-Lay plant in Denver in the early morning of August 31. She was believed to have left in a green 1967 Chevrolet Nova and was married with four children at the time.

About a week after she disappeared the family received a letter thought to be from Colleen saying she had a terminal illness and had chosen to disappear so her loved ones would not see her decline. There was no further contact. The husband reported her missing, but the case file was removed from the police system and not re-entered until 1980. A 2010 review found no medical records to support the terminal illness claim, and investigators could not locate records of a prior missing-person report that was mentioned.

Colleen was described as white, red or auburn hair, hazel eyes, 5 feet 6 inches to 5 feet 7 inches, about 130 to 135 pounds. The Englewood Police Department continues to list the case open. Does anyone have memories or information about Colleen, her car, or that week in 1974 that could help fill in the gaps?
