CHICAGO — A Northwestern University professor and journalism students who spent three years trying to show the wrong man was convicted in the 1978 killing of a security guard may have to defend themselves.
Cook County prosecutors have issued subpoenas to professor David Protess for his students’ grades, his syllabus and their e-mails. Prosecutors claim the students may have been under pressure to prove the case to get a good grade.
Protess and his investigative reporting students have helped free 11 innocent men from prison, including death row, since 1996.
