About the Registry

The National Registry of Exonerations is a joint project of the University of Michigan Law School and the Center on Wrongful Convictions at Northwestern University School of Law. We provide 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.

Exoneration News


​Newly-elected Philadelphia District Attorney Seth Williams has created a Conviction Integrity Unit to investigate claims of innocence from defendants who contend they were wrongly convicted. The unit is part of a growing trend by prosecutors to respond to innocence claims, and to help prevent false convictions in the future. Similar units have been established in numerous jurisdictions, including Dallas County, Texas; Santa Clara County, California; Baltimore City, Maryland; Cook County, Illinois; Manhattan and Brooklyn. The Philadelphia unit will receive innocence cases from the Pennsylvania Innocence Project at Temple Law School.
