Exonerated after 38 years, Peter Sullivan fights for compensation as real killer's DNA remains unmatched.

Peter Sullivan, 68, spent 38 years in prison for a murder conviction that was overturned after new DNA evidence excluded him. The Court of Appeal quashed his conviction, calling it "impossible to regard as safe." Sullivan must now prove his innocence to claim compensation. Meanwhile, efforts continue to identify the actual murderer whose DNA was found at the crime scene.
