Claremont killings trial: prosecutor says crucial DNA evidence 'unmasked' serial killer

Carmel Barbagallo says there is physical and circumstantial evidence against Bradley Robert Edwards but defence says case hinges on tiny gram of cellular material

Bradley Robert Edwards has been unmasked" as the Claremont serial killer after months of evidence that gradually cast a light on the enigma of the dark", prosecutors allege.

The 51-year-old denies murdering secretary Sarah Spiers, 18, childcare worker Jane Rimmer, 23, and solicitor Ciara Glennon, 27, in 1996 and 1997. He did not testify at his judge-alone Western Australian supreme court trial.
