"The Devil's Half Acre": How one enslaved woman left her mark on education

In Virginia's capital city, trapped between a railroad yard and an interstate highway, a renewed landscape has unlocked the legacy of a stolen people. "I was doing research to learn more about the slave trading district down here," said journalist Kristen Green.

That research led to one woman whose story haunted Green for nearly a decade. "I just couldn't forget Mary Lumpkin," she told CBS News. "Like, once I learned about her, I thought her story was so important and needed to be shared."

On assignment in 2011 for the Richmond Times-Dispatch, Green reported on the very place that enslaved woman lived, the nation's largest African American burial ground, a final resting place for some 200,000.
