Details of Disappearance
Mason was last seen in Highland, Michigan on April 25, 1983. She went for a walk to the corner store, never returned and has never been heard from again. She was attending college at the time of her disappearance, and it's uncharacteristic of her to leave without warning or abandon her son, whom she was devoted to.
A witness reported seeing a man approaching Mason near the store, but the man has never been identified. She did have an abusive former boyfriend; shortly before her disappearance, he had kidnapped her and beaten her so badly she had to be hospitalized.
Mason's ex-boyfriend has never been named as a suspect in her case, however, and her disappearance remains unsolved.
