I want to know the answer to the following question:
In 1999, who uncovered information that exonerated death row inmate Anthony Porter only 2 days before his scheduled death?
All the background I'm provided with is that "On January 11, 2003, in a speech at Northwestern School of Law's Lincoln Hall, then Governor of Illinois George Ryan announced that he would commute the sentences of more than 150 death row inmates.". Is that enough to answer the question?
Answer: no
