The prime suspect walks free for the murder of Nora Sheehan after the death of the pathologist left the DPP's case unable to proceed to trial. 

In this second chapter of a two-part investigation, John Sweetman looks at how four decades after Nora Sheehan’s disappearance and death in 1981, advances in forensic technology breathed new life into a long-dormant investigation. 

 In this episode, we explore how preserved evidence from fibres and paint fragments to a partial DNA profile was re-examined by investigators as as long-preserved traces ignite a renewed hunt for answers.
