Peter Dupas

Peter Norris Dupas is an Australian serial killer, currently serving three consecutive life sentences for murder. His violent criminal history spans more than three decades, and with every release from prison has been known to commit further crimes against women with increasing levels of violence. His criminal signature is to remove the breasts of his female victims.

Dupas was the youngest of three children, born into what has been described as a fairly normal family. Born in Sydney, New South Wales, his family moved to Melbourne while he was still a toddler. With both siblings considerably older, his elderly parents treated him much like an only child. Dupas left high school upon completing Form 5, and later obtained his Higher School Certificate.
