The University of Michigan and Northwestern University studied wrongful convictions and found since 1989, more than 400 people innocent people were convicted of murder.
Two universities have created a registry of wrongful convictions and put together the most comprehensive study on the subject, finding more than 400 people convicted of murder since 1989 were eventually exonerated and freed. News12 explains the study’s scope and details a few findings. “...the report lists the details of 900 exonerated cases since 1989 and an additional 11 hundred group exonerations. the groups involved corrupt police officers who made up the charges and planted evidence. the goal of the list is to help the justice system better identify wrongful convictions.” The Los Angeles Times notes the study is incomplete -- not every exoneration is in the registry. But notes the report also found a surprising number of false confessions -- in which people said they committed crimes after interrogation or police pressure. The Atlantic runs down some numbers from the study. “Not surprisingly, most of the men and women who were wrongfully convicted (61 percent) were black or Hispanic. As a group, the 873 exonerated defendants spent more than 10,000 years in prison -- an average of more than 11 years each. And of the 873 exonerees, nearly half, 416 to be exact, were wrongly convicted of murder. Of those, 101 were sentenced to death.” KOKI reports on the most common means of exoneration and most common sources of wrongful conviction. “DNA evidence played a big role in overturning homicide and sexual assault convictions. many wrongful convictions were based on false accusations, and almost half were mistaken identities.” The study was a collaboration of the University of Michigan and Northwestern University.
