Yesterday, Cook County State’s Attorney Anita Alvarez spoke with Alison Cuddy about a subpoena that’s sparked a high-profile fight between prosecutors and a college professor. Alvarez is demanding to see grades and off-the-record notes from an investigation by students at Northwestern University’s Medill School of Journalism. The students were working on the school’s Innocence Project — and they say they have clear evidence that a man was wrongfully convicted for a 1978 murder. But Alvarez says she has reason to believe the student investigation was flawed — and that her office needs more information to complete its own investigation. David Protess, director of the Medill Innocence Project, responds to the allegations.
