They are tallying the damage in Illinois:

Wrongful convictions of men and women for violent crimes in Illinois have cost taxpayers $214 million and have imprisoned innocent people for 926 years, according to a seven-month investigation by the Better Government Association and the Center on Wrongful Convictions.





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...





Moreover, the 97 felonies in that crime spree may be just a fraction of the total number of crimes committed by the actual perpetrators. The investigation found that the 85 exonerations left 35 murders, 11 rapes, and two murder-rapes with no identified perpetrators and thus no way to add up their accumulated crimes.
