EXCLUSIVE: ‘Bite marks’ sent him to death row. A video helped set him free.

When Jimmie Chris Duncan heard the Louisiana Supreme Court had agreed to toss his murder conviction, he cried with relief. He had fought the accusation that he killed his girlfriend’s toddler for decades — including 27 years on death row.

But he couldn’t fully exhale: “They’re never going to own up to the things that were done,” Duncan, 57, said in his first interview since the June 29 decision.

His conviction was predicated on bite marks that a forensic pathologist, Steven Hayne, and a forensic dentist, Michael West, found on the toddler’s body after her death. Video later revealed the marks were created when West pressed a mold of Duncan’s teeth to the toddler’s skin, forensic experts said.

Duncan is one of at least 10 people — and the fourth death row prisoner — found to have been wrongly convicted based on discredited work by Hayne or West. There is no way of knowing how many innocent people remain in prison as a result of their findings.
