ST. LOUIS (AP) -- A new report says a record number of people who were falsely convicted in the U.S. were exonerated in 2013.
Now, prosecutors nationwide are pushing to re-examine possible wrongful convictions because of the record number of exonerations.
The National Registry of Exonerations says 87 people falsely convicted of crimes were exonerated last year. Efforts by the Northwestern University and University of Michigan law schools show that nearly 40 percent of those exonerations were initiated either by law enforcement or included police and prosecutors' cooperation.
Texas had the most with 13 exonerations in 2013, followed by Illinois, New York, Washington and California.
District attorneys in Chicago are among those with new "conviction integrity" units.
