Imagine spending decades in prison for a crime you didin't commit. Unfortunately this is a reality for inmates who've been wrongly convicted. But now a thanks to a pioneering unit in the Dallas County's D.A.'s office, post-conviction DNA testing is being used to clear the innocent as well as confirm the guilty.  Since the program's inception in 2001, more than 40 cases have received post-conviction DNA evidence--resulting in 19 deemed as wrongful convictions.
 
Upon his election as district attorney in 2007,  Dallas Ditrsct Attorney Craig Watkins created the nation's first Conviction Integrity Unit (CIU) which has re-examined hundreds of petitions submitted by inmates claiming their innocence.  Under his supervision, ten innocent men have been freed.
 
Seeking justice through post-conviction DNA testting is the subject of  "Dallas DNA" which premieres on the Investigation Discovery
Channel on Tuesday, April 28th at 10 pm.
