Cold Case Files

Students of the University of Cincinnati and Texas Tech University Innocence Project take on the cases of jailed murderers who claim they're innocent. With exclusive, behind-the-scenes access, viewers watch as the students visit the inmates, track down key witnesses, and seek DNA testing that could prove their clients' innocence. While their focus is on the cases of Texas death row inmate, Anthony Graves, and mentally ill Ohio inmate Glen Tinney, who plead guilty but now professes his innocence.
