Psychologist Dr Leah Giarratano tells viewers what led these two violent, sexual predators to commit these shocking crimes. Together, David John Birnie and his wife, Catherine Margaret Birnie, overpowered Mary Nielsen, gagged and chained her to the bed. Birnie is one of that rare breed - a female serial killer. Ms Moir managed to escape through a window and ran for her life - unaware the couple had already killed four young women. Catherine Birnie was found to be carrying a diary written by Stasinowski, and it was suspected she was facilitating letters between the two. David Birnie lost touch with Catherine, at least for a while. Uncharacteristically, she failed to show up at her office to work and was not home to meet her daughters returning from a weekend with their father. David Birnie continued his violent temperament in prison and was often in the middle of fights, beaten up, and spent much time in the prison infirmary. Catherine Birnie told one visitor: I could have stopped that girl. David Birnie died by suicide in prison in 2005 and Catherine Birnie is currently in prison.
