It was bitter cold in early January 2008. But despite the frigid temperature, it seemed like the entire world had come out to search Blood Mountain in North Georgia. They were looking for Meredith Emerson, who had disappeared on a New Year's Day hike with her dog Ella.

“I think about Meredith every day. Every single day,” said John Cagle, the GBI agent who led the search for Emerson and her abductor.
