Carolyn Sue Martin, known as Sue, was 24 when she and her two-year-old son Mark Steven Martin disappeared from the Madison Heights/Hazel Park area on August 31, 1981. They were leaving Michigan in a black 1978 Pontiac Grand Prix, reportedly headed for San Antonio, Texas, where Carolyn planned to join her fiancé, Hamparsoum Harry Kirezian. Carolyn was described as a White woman about five feet five inches tall, 110 pounds, with shoulder-length brown hair and very light blue eyes.

Friends and family helped pack that day and Carolyn visited her mother that evening to say she and Mark would take a different route than her twin brother, who was traveling to Oklahoma. Kirezian, the last person reported to have seen them, later told police he and Carolyn argued near Toledo, Ohio, and that he left her and the child at the side of the highway with one suitcase and $4,000. No precise location was given, no confirmed witnesses saw them after they left Michigan, and there has been no activity on either of their Social Security numbers.

The Pontiac was sold in 1982 and later retitled in Minnesota; no publicly confirmed physical evidence from the car or the journey has been reported. Foul play is strongly suspected and the investigation remains open with the Madison Heights Police Department. Did anyone in the Toledo or San Antonio area ever see Carolyn or a woman traveling with a small child around late August or early September 1981?
