Criminal Exonerations: 2,000 Convicted Then Exonerated in U.S. Over Last 23 Years, Says Study
More than 2,000 people who were falsely convicted of serious crimes have been exonerated in the United States in the past 23 years, according to a new archive compiled at two universities.
There is no official record-keeping system for exonerations of convicted criminals in the country, so academics set one up. The new national registry, or database, painstakingly assembled by the University of Michigan Law School and the Center on Wrongful Convictions at Northwestern University School of Law, is the most complete list of exonerations ever compiled.
The database compiled and analyzed by the researchers contains information on 873 exonerations for which they have the most detailed evidence. The researchers are aware of nearly 1,200 other exonerations, for which they have less data.
They found that those 873 exonerated defendants spent a combined total of more than 10,000 years in prison, an average of more than 11 years each. Nine out of 10 of them are men and half are African-American.
Nearly half of the 873 exonerations were homicide cases, including 101 death sentences. Over one-third of the cases were sexual assaults.
DNA evidence led to exoneration in nearly one-third of the 416 homicides and in nearly two-thirds of the 305 sexual assaults.
Researchers estimate the total number of felony convictions in the United States is nearly a million a year.
