Mary Kay McMillan was 40 when she was last seen in Columbia Heights, Minnesota, on Thursday, December 28, 2000. She was known to spend time in nearby Coon Rapids and northeast Minneapolis. Mary is described as a white female, brown graying hair, blue eyes, about five feet five inches and 125 pounds, with scars on the tip of her nose and under her chin.

Her apartment was found undisturbed, with no obvious sign of a struggle or a planned departure. The notable missing piece is her vehicle, which disappeared along with her and has never been located. Investigators found very few clues, and foul play has not been ruled out. The Columbia Heights Police Department has kept the file open but the case has since gone cold.

If anyone saw Mary, her car, or has information about her movements around December 28, 2000, please come forward.
