After her husband, a California state assemblyman named Benjamin Colerige Turner, found out that she was a demon three years after the birth of their son, Elizabeth killed him with an Energy Ball, as witnessed by Phoebe Halliwell in a premonition. Later, when Phoebe was creating a document with notes on Belthazor, she listed Elizabeth as a demon, noting that she could possibly still be alive. When Cole was stabbed with the Ancient Athame, the moment that Elizabeth killed Benjamin was one of the many memories that were seen in the void.
