Erin Kimmerle

31 was only the number the state had reported buried there.

And as Erin Kimmerle, a forensic anthropologist from the University of South Florida, stood there staring at the metal crosses and the pitiful fencing, she had a feeling that they'd find many more boys in that makeshift cemetery.

Her experience working on genocide cases and identifying remains in mass graves in the Balkans, Nigeria, and Peru told her as much.

She also knew that at many state hospitals and other institutions, burial records and maps could be detailed enough to lead families to the exact spot where a loved one had been buried.
