In May of 2014, Georgia couple Russell and Shirley Dermond were invited to a party at a friend's house, but failed to show up. Days later, friends became worried after no contact was made with the couple, both in their 80s, since then. When someone went to check on them, they found Russell's decapitated body in the garage and Shirley was missing. What happened on that day is still a mystery and one of Putnam County's most baffling cold cases.
