Seven-year-old Diana Moon Yoli and her younger half-brother Mark were last seen about 3:15 p.m. on September 13, 1962, when they left for the playground in Midway Park, the housing community at Camp Lejeune, North Carolina. Diana was described as blonde with blue eyes and known to wander; when the children failed to return their mother searched the playground and a large-scale effort followed. More than a thousand U.S. Marines searched woods and swamps for four days, and residents were interviewed repeatedly, but no trace of either child was found.

Decades later, in 1992, the former wife of a man identified as Henry Morris Hunt said on her deathbed that Hunt had told her he picked the children up to go fishing, that Mark fell into the water and drowned, and that Hunt then killed Diana and disposed of the bodies in a rock quarry or mine shaft near Maysville. Searches of quarries yielded no evidence, and bones found beneath Hunt’s demolished former home in 2011 were identified as animal remains. The disappearances of Diana and Mark remain unsolved.

If anyone knew the children, lived in Midway Park in 1962, or has information about the Maysville-area quarries or Hunt’s movements, please share what is known.
