One hundred and thirty eight people have been exonerated of capital crimes and released from death row since 1973. These tragic stories don't always get told, but two professors wanted to make sure that the voices of some exonerees were heard. Saundra Westervelt and Kimberly Cook explore the post-incarceration struggle of 18 of them in their new book “Life After Death Row: Exonerees’ Search for Community and Identity” (Rutgers University Press/2012).
