In 2006, underworld figure Lee Patrick Torney vanished without a trace. Nearly a year later, forensic anthropologist Dr. Soren Blau was lowered into an abandoned mineshaft outside the old gold-mining township of Chewton, near Castlemaine, Victoria. Soren pieced together the secret clues hidden on the surface of bones and what they showed about injuries and the circumstances of death.

Soren also revisits another landmark case that reshaped forensic science, with the first ever exhumation of a murder suspect in the United Kingdom.

Host Liz Porter sits down with Soren to find out how her pioneering use of familial DNA helped unmask a serial killer.
