HILTON HEAD ISLAND, SC (WTOC) - The Investigation Discovery network is profiling the missing persons case of Hilton Head couple Elizabeth and John Calvert in the next episode of "Disappeared." It premieres at 10 p.m. on Nov. 1.
The Calverts ran a boating resort business, Harbour Town Yacht Basin, in South Carolina.
But after a meeting with their former accountant, Dennis Gerwing, the couple went missing. The Calverts were last seen on March 3, 2008.
Gerwing killed himself early on in the investigation after being named a person of interest in their disappearance. The Calverts' bodies have never been found. A judge has since declared them dead.
