Summary based on the NamUs case record (MP2421) and 2 other sources
In December of 1983, a 29-year-old man named Mark Skinner Clarke vanished from Tuckasegee, North Carolina, leaving behind a trail of perplexing circumstances and unanswered questions for his loved ones. Standing at 69 inches and weighing around 155 pounds, with brown hair and blue eyes, Mark's physical appearance was further distinguished by a scar from a previous neck injury and a burn scar on his right knee. In the year of his disappearance, he was known to have a full beard. The period leading up to his disappearance was marked by a significant shift in his life and relationships.

Mark's family reported that he had become estranged from them after joining the L'Abri Christian Fellowship of England in 1982, which led to difficulties with some friends and loved ones. His parents last saw him in January of that year when he was also seeking medical treatment for fatigue. The last communication they had with him was in January 1983. Investigations suggest that in early December 1983, a member of the L'Abri Fellowship may have put Mark on a plane to either Baltimore, Maryland, or Washington D.C. From there, it is believed he traveled by bus to Asheville, North Carolina, where he stayed in a motel on December 24, 1983.

Following his stay in Asheville, Mark rented a car and drove to Tuckasegee with a friend. The journey continued to Atlanta, Georgia, where he dropped off his friend before proceeding to Columbia, South Carolina, to visit another friend. He stayed in Columbia for three days before returning to his hometown of Tuckasegee. According to friends, Mark did not want his parents to know he was in the area during that time. He was known to lead a transient lifestyle, did not use credit cards, and made all his purchases with cash. There has been no contact with Mark Clarke since December 1983, and the friends he was with during that final period confirmed they have not heard from him since. The case remains a poignant mystery, centering on a young man's sudden and complete disappearance after a period of personal upheaval and cross-country travel.
