Wrongful_Convictions

Better Government Association and the Center on Wrongful Convictions tracked wrongful convictions in Illinois from 1989 through 2010:

The joint investigation, which tracked exonerations from 1989 through 2010, also determined that while 85 people were wrongfully incarcerated, the actual perpetrators were on a collective crime spree that included 14 murders, 11 sexual assaults, 10 kidnappings and at least 62 other felonies.
