Mary Elizabeth McMaster, known as Mayte, was 31 when she was last seen in Winnsboro, South Carolina, on May 3, 1983. A family member saw her at her West High Street residence; she left that day in the company of her friend Deborah Ernandez. Both women disappeared after leaving the house and their whereabouts have been unknown since.

Mary was described as five feet four inches tall, weighing 110 to 125 pounds, with blonde or strawberry-colored hair and hazel eyes. Deborah’s car was later found abandoned in Richland County; there is no information about any vehicle Mary may have been driving. That discovery did not yield clear leads and the timeline of the women’s movements after they left the house remains incomplete.

The case remains an active missing persons investigation and has offered no closure for the families. Did anyone in Winnsboro or Richland County remember seeing Mary or Deborah, or saw Deborah’s car on or after May 3, 1983?
