It’s been more than two months since Savannah, Ga., lawyer and Hilton Head Island, S.C., resident Elizabeth W. “Liz” Calvert and her husband, John, disappeared.

A week after the couple’s March 3 disappearance, her law firm, HunterMaclean, asked a Savannah pastor to hold a prayer service for its missing partner and her husband in one of the city’s squares, said its managing partner, John M. Tatum, but hope for their return is dwindling as the weeks pass.
