Check out this article in the New York Times. Joseph A. Buffey has been in prison now for more than a decade for a brutal rape he did not commit. The post-conviction proceedings have taken more than 18 months, and although his defense team has succeeded in getting DNA testing that excluded Buffey as the rapist done in May 2011, Buffey still remains in prison. Furthermore, when DNA was run through a government database, it matched another individual who has a history of assaulting women.
The Innocence Project is doing an incredible job with this case.
