guess all our life. one night he called me and he told me i lied and my conscience is bothering me. >> gilliam said he made a deal with the prosecutor to testify against elmore in exchange for release from prison. but with elmore facing the electric chair, he felt bad what he had done. >> i said james, make it right. and i got excited. i felt like once this comes out that ed would be free. >> gilliam said the testimony that i gave in these prior trials was false. that he made up this story to try to get better treatment for himself on his criminal sentence. >> gilliam would go on to state that the only thing elmore had ever said was that he didn't kill dorothy edwards. but diana's team also felt they needed to refute dorothy edwards' time of death which the medical examiner had placed on saturday night during the only hours elmore had no alibi. diana hired forensic expert jonathan arden. >> in my opinion the victim died in the early afternoon on sunday. that time frame makes sense with the rigor mortis, the lack of decomposition.
