The first time DNA evidence was used to free a wrongfully convicted person was back in 1989. Since then, as forensic science has improved, another 324 people have been released from prison based on DNA testing. Plenty more are likely on the way.

If you add up all the time these men and women have served for crimes they did not commit, that number would equal 5,192 years. According to data provided by the Innocence Project, the DNA exonerations were spread across 37 states, plus Washington, D.C. Below is at look at the number of people exonerated and time stolen by state.
