On September 13, 1962, seven-year-old Diane Moon and her younger half-brother Mark Yoli were last seen walking toward a playground in the Midway Park housing area at Camp Lejeune, North Carolina. Diane was described as a blonde with blue eyes, wearing a print or white sleeveless blouse and shorts. Their parents initially expected the children to return, but after they did not, more than 1,000 Marines conducted a four-day search that turned up no trace of them.

A major development came in 1992 when the ex-wife of convicted child molester Henry Morris Hunt, on her deathbed, told her daughter that Hunt had confessed. She said Hunt claimed he had taken the children fishing after picking them up from Midway Park, that Mark accidentally drowned, and that Hunt then killed Diane and disposed of both children in a mine shaft or rock quarry near Maysville, North Carolina. Searches of the area were hindered because the quarries and lakes had changed over the decades.

Bones found under Hunt’s former, later-demolished home in 2011 were tested and identified as animal remains. No human remains connected to Diane or Mark have been recovered, and no other suspect is named in the case. Does anyone have information about the Midway Park playground, the Maysville quarries, or memories of Diane and Mark before they vanished?
