The National Registry of Exonerations is the most comprehensive collection of exonerations in the United States ever assembled.
The great majority of false convictions never result in exoneration. Exonerations are most common among defendants wrongly convicted of the most severe violent crimes – especially murder and rape – and for those sentenced to death, life in prison, or many years in custody. Even then, whether or not a falsely convicted defendant is exonerated often depends on sheer luck.
The Registry was launched in May 2012 with a Report covering 873 exonerations from 1989 through February 2012. Since then, the Registry has added exonerations at a rate exceeding 200 a year.
About a third of the newly added exonerations are current cases which are posted within days or weeks of their occurrence. About two thirds are previously unknown exonerations that occurred months, years or decades before.
The previously unknown cases illustrate a central conclusion of our research: The exonerations we know about are just a fraction of those that have taken place.
As we continue to identify old exonerations that have remained unknown to us, we expect the range and diversity of the exonerations we list to continue to grow. For example, 83% of exonerations in our initial Report involved a rape or a murder, compared to only 62% of exonerations in the same period that were identified later by more painstaking research.
The National Registry of Exonerations is a project of the Newkirk Center for Science & Society at University of California Irvine, the University of Michigan Law School and Michigan State University College of Law. It was founded in 2012 in conjunction with the Center on Wrongful Convictions at Northwestern University School of Law. The Registry provides detailed information about every known exoneration in the United States since 1989—cases in which a person was wrongly convicted of a crime and later cleared of all the charges based on new evidence of innocence. The Registry also maintains a more limited database of known exonerations prior to 1989.
We welcome new information from any source about exonerations already on our list and about cases not in the Registry that might be exonerations.
