Identified by the victim, Ronald Cotton spent eleven years in prison for rape. But in 1995, DNA evidence proved Cotton could not have been the attacker. With unprecedented access to the central figures in the investigation, confidential police reports and legal files, FRONTLINE delves into the Cotton case, examining the reliability of eyewitness identification and the implications of DNA evidence for the American justice system. In an exclusive interview, Jennifer Thompson tells the story of her brutal rape and how, twelve years later, she must confront the consequences of her mistaken identification.
