Keith Hayward, age 59, has spent 33 years in prison due to a wrongful conviction of raping a woman then murdering her husband. The surviving victim stated that the attacker held a diaper over her head as he raped her and that he bit at her legs as her husband laid next to her dying. Experts testified that the photographs of the bite marks on the victim “fit on the money” with the defendant’s teeth alignment. Bite mark evidence has since been widely discredited by experts and forensic science organizations. DNA testing has exculpated Hayward, but it is not clear if investigators have run the DNA sample through a database or if another suspect has been implicated.
