A report released February 2014 by the National Registry of Exonerations, a joint project of the University of Michigan Law School and the Center on Wrongful Convictions at Northwestern University School of Law, shows that there were a record number of exoneration nationwide. The number of reported exonerations of people who were wrongfully convicted of a crime they did not commit– and who served prison time– rose to 87 in 2013. The previous record was 83 in 2009.

Samuel Gross, editor of the National Registry of Exonerations, notes that while the number may seem small, “The great majority of people who are innocently convicted are never exonerated because they are never discovered.”
