FILE - In this Feb. 5, 1999 file photo, death row inmate Anthony Porter left, hugs former Northwestern University journalism professor David Protess after being released from prison, in Chicago. Cook County State's Attorney Anita Alvarez' office vacated murder and voluntary manslaughter charges against Alstory Simon who was serving a 37-year prison term for a 1982 double murder, Thursday Oct. 30, 2014. Protess' Innocence Project helped free Porter, who had been charged in the slayings. Alvarez was very critical of the investigator, Paul Ciolino, and Protess' work to free Porter that led to the confession by Simon. (AP Photo/Beth A. Keiser,File)
