Dallas DNA
Dallas DNA is an American television series that premiered on the Investigation Discovery cable channel on April 28, 2009, and has since been renewed for a fourth season. It provides documentation of the District Attorney's Office in Dallas County, Texas's collaboration with a number of law school innocence programs. Conviction Integrity Unit, a new component of the Texas Department of Criminal Justice, re-investigates historical convictions in which DNA testing may exonerate or confirm the guilt of persons currently serving time in Texas prisons.
