Two universities have released what they say is the largest database of criminal exonerations in the U.S. ever put together.
The registry was assembled by the law schools at the University of Michigan and Northwestern University.
It includes nearly 900 exonerations since 1989.
The inaugural report also discusses more than 11-hundred other exonerations.
Those convictions were dismissed in group exonerations in the wake of more than a dozen police scandals.
In the scandals, police fabricated crimes usually by planting guns or drugs on innocent people.
The registry's goal is to prevent wrongful convictions and help the justice system better identify and correct them.
