Mary Ann Hutchinson was 21 and a mother to a five-year-old when she vanished from Evanston, Illinois. She was last seen on July 19, 1979; her mother, Jane Hutchinson, reported her missing to the Evanston Police Department on July 22, 1979. At the time she was described as a Black female with black hair, five feet tall and about 98 pounds.

Mary Ann had been separated from her husband when she disappeared. She worked at a Chase bank after getting the job through a high school jobs program and was one of the first Black female employees at that branch. Family members described her as quieter than her five siblings and fond of reading. Her sister has said she believes she knows who is responsible, but no remains or conclusive evidence have been found and the case remains unsolved.

The Evanston Police Department still lists Mary Ann as missing. If anyone has information about her disappearance, please contact Evanston police.
