Five years ago, Chris Turnbow left home in Marion, Ark., and just disappeared.
His family had reason to believe he was living in New Orleans; a family friend had bumped into him there at Mardi Gras. But that was before Hurricane Katrina. Turnbow's mother, Jean Aaron, tried not to consider whether his long silence meant he was alive or dead.
Earlier this month, 69-year-old Jean heard her son's voice for the first time since he had left home. She heard him on National Public Radio's All Things Considered, in a story about homeless people living in Duncan Plaza, a park in front of City Hall. (NPR)
