Donna Kay Kingston was 18 years old when she disappeared from Tahlequah, Oklahoma, on May 11, 1984. She is a member of the Cherokee Nation and was known by the nickname Dirteater. 

Shortly before she vanished, Donna told her family that she had met a man from Tulsa who claimed she could make money if she traveled there with him. Her family did not know the man, and no one knew anything about him. Despite the uncertainty, Donna decided to make the trip.

Donna left Tahlequah driving her grandmother's red and white four-door 1980 Mercury Monarch bearing Oklahoma license plate CZ4818. Before leaving, she told her grandmother that she would call as soon as she arrived in Tulsa. That phone call never came.

Neither Donna nor her grandmother's vehicle has ever been found. There have been no confirmed sightings of Donna since the day she left, and investigators have never publicly identified the man she planned to meet. Over the years, very little evidence has surfaced to explain what happened after she left Tahlequah. 

Authorities believe it is completely out of character for Donna to have voluntarily disappeared without contacting her family. Because of the circumstances surrounding her disappearance and the complete lack of contact for more than four decades, investigators now classify her case as a probable homicide. 

At the time she disappeared, Donna was between 5 feet 4 inches and 5 feet 5 inches tall and weighed between 140 and 165 pounds. She had black to dark brown hair, brown eyes, a small mole on her right cheek, and protruding upper front teeth. She had previously worn braces, but they had been removed before her disappearance.

Donna Kay Kingston has never been located, and both she and the Mercury Monarch she was driving remain missing.
