In light of the new evidence uncovered by the film, an evidentiary hearing was held. David Harris testified, recanting his earlier testimony against Randall Adams. "Randall Adams knew nothing about this offense and was not in the car at the time," Harris testified. Adams' capital murder verdict was overturned, and he was released from prison in March 1989. Adams then filed suit against filmmaker Errol Morris over the rights to his life.
David Harris, at age 43, was executed by lethal injection on 6/30/04 in Huntsville, TX, for murdering a man, Mark Mays, during an attempted kidnapping. That crime occurred on 9/1/85, and was unrelated to Harris's murder of the police officer discussed in this film. The Mays case was mentioned in the film, in which Harris was wounded in the neck before the victim was killed.
