Elizabeth Calvert, 45, and her husband John were last seen together on Hilton Head Island, South Carolina, in the late afternoon of March 3, 2008. The couple split time between a home in Atlanta and their yacht Yellow Jacket, docked at Harbour Town marina, and were described as having regular routines and close family contact. They missed business appointments the next day and their phones and PDAs were turned off.

Their silver Mercedes was found abandoned in a resort parking lot six miles from the marina. Their small plane remained at the local airport and a dive-team search of the marina and waters turned up nothing. The couple’s accountant, Dennis Gerwing, was the last known person to see them; his account reportedly contained inconsistencies. Investigators noted he had recently bought large drop cloths, had a cut on his hand consistent with a slide bite from a semi-automatic pistol, and later admitted in suicide notes to embezzling from the Calverts. Gerwing died by suicide on March 11, 2008; a .22 Beretta holster was found at his home but the firearm was not recovered.

The Calverts’ bodies have never been found and the case remains unsolved; investigators’ prevailing theory is that Gerwing killed the couple after being confronted about embezzlement. Did anyone on Hilton Head or in the boating community see the Yellow Jacket, the Mercedes, or the Calverts around March 3–4, 2008?
