Two-year-old Mark Eugene Yoli and his older half-sister Diana disappeared from a playground near their Midway Park housing area at Camp Lejeune, North Carolina, on the afternoon of September 13, 1962. The children were last seen about 3:15 p.m.; Mark was described with dark brown hair and brown eyes and was wearing a t-shirt and brown shorts. An extensive four-day search of the base and nearby swamp produced no trace of either child and the case quickly went cold.

Decades later, in 1992, the dying wife of convicted child molester Henry Morris Hunt told her daughter that Hunt had claimed to have taken the children fishing, that Mark had accidentally drowned, and that Hunt had killed Diana and disposed of both bodies in a mine shaft near Maysville, North Carolina. Bones found in 2011 under Hunt’s former home were tested and determined not to be human, and investigators concluded the altered landscape around the mine shaft made a productive search unlikely. Foul play is strongly suspected but both children remain missing.

If anyone has information about the Midway Park playground, the Camp Lejeune area in 1962, or the Yoli family’s movements that afternoon, please share what is known.
