Two prisoners in separate cases are both newly freed men today after DNA tests cleared them of their convictions. In Georgia, Willie “Pete” Williams was set free Tuesday after DNA evidence overturned a rape conviction that had jailed him for nearly 22 years. His release came just hours after another convict, Roy Brown, was released here in New York state. Brown was sent to jail 15 years ago following his conviction for rape and murder. He was exonerated mostly due to his own efforts. Working from his jail cell, Brown gathered evidence to accuse the brother of the victim’s boyfriend of the crime. When the man committed suicide, testing later proved his DNA was on the victim’s shirt the night she was killed. The Innocence Project says DNA testing has now exonerated nearly 200 people across the nation.
