Cold Case: Mom Pamela Ray vanishes during beach road trip with kids

A Georgia mom took her kids on a beach road trip, but the family slept in their car the first night because none of the motels in Panama City, Florida, had a room available. That mom -- Pamela Ray -- disappeared during the early morning hours of that day in 1992. Nancy Grace talks to Ray's sister, Rhonda Bishop, in an effort to revive the cold case mystery. They are joined by Cold Case Research Institute director Sheryl McCollum, forensic psychiatrist Dr. Daniel Bober, Atlanta lawyer Penny Douglas Furr, and reporter Alan Duke.
