Those exonerated by DNA testing aren’t the only people who have been wrongfully convicted in recent decades. For every case that involves DNA, there are hundreds that do not.
Only a fraction of criminal cases involve biological evidence that can be subjected to DNA testing, and even when such evidence exists, it is often lost or destroyed after a conviction. Since they don’t have access to a definitive test like DNA, many wrongfully convicted people have a slim chance of ever proving their innocence.
These factors are not the only causes of wrongful conviction. Each case is unique and many include a combination of the above issues. Review our case profiles to learn how the common causes of wrongful convictions have affected real cases and how these injustices could have been prevented.”
