CHICAGO (CBS) — The Cook County State’s Attorney has been re-evaluating a 1982 murder case to see if the right man is in prison, and WBBM has learned there are developments in the case.

WBBM Newsradio’s Steve Miller reports prosecutors met Monday with Alstory Simon, who is serving a 37-year sentence for a double murder in 1982.

Initially, Anthony Porter convicted of the killings, and sent to death row, but he was freed after a Northwestern journalism professor and class obtained a confession from Simon in 1999

Since then, Simon has said his confession was coerced. His lawyers have said a private investigator with the Medill Innocence Project told Simon if he confessed to killing Marilyn Green and her fiancé Jerry Hillard in self-defense, he’d only serve a short time, and would get rich from book and movie deals.

Witnesses in the case have since recanted.

Advocates are now working to free Simon, and as WBBM first reported six months ago, State’s Attorney Anita Alvarez began a review of the Simon case.

Now prosecutors have met with Simon himself.
