Russell and Shirley Dermond had been married for more than 60 years when they were murdered in May 2014.

Mr. Dermond was found decapitated in his home in Putnam County, Ga. There was no sign of his wife.

Ten days later, her body was found floating face-down in a nearby lake. Her ankles were tethered to two 30-pound cinder blocks.
