This returning series tells the story of nine murder cases – each one resolved thanks in part to the role of forensic science.

In each episode a single case is unpacked in detail to discover how the forensic work helped catch a killer.

These voices take us through the various twists and turns of each case, explain how the investigation unfolded and how ultimately forensic science helped lead to the killer’s capture and conviction.
