Summary based on the NamUs case record (MP62421) and 9 other sources
In the small town of Winnsboro, South Carolina, a long-standing mystery began on May 3, 1983. On that day, 31-year-old Mary Elizabeth McMaster, affectionately known as "Mayte" to her loved ones, was last seen by a family member at her residence on West High Street. She was in the company of her friend, Deborah Ernandez, who also disappeared on the same day. The two women left the house together, and what happened to them after that moment remains unknown. At the time of her disappearance, Mary was described as being five feet four inches tall, weighing between 110 and 125 pounds, with blonde or strawberry-colored hair and hazel eyes.

The circumstances surrounding the double disappearance of Mary McMaster and Deborah Ernandez are clouded with uncertainty. While details about any vehicle Mary may have been driving are unknown, Deborah's car was later discovered abandoned in Richland County. This discovery, however, provided no significant leads in the investigation into what happened to the two women. The lack of information about Mary's potential vehicle has left a significant gap in the timeline of their last known movements. Authorities have been left with very little evidence to piece together the events of that fateful day, and the case has grown cold over the decades that have passed.

The disappearance of Mary McMaster and Deborah Ernandez has left their families in a prolonged state of grief and uncertainty. Decades have passed without any significant developments or answers, leaving a void in the lives of those who knew and loved them. The case remains an active missing persons investigation, a painful reminder of two lives that seemingly vanished without a trace. The overview of this case is one of enduring mystery and unanswered questions. Two friends were last seen together and then disappeared, with only one of their vehicles being found abandoned. The lack of substantial leads has left law enforcement with a decades-old cold case and has provided no closure for the families.
