On Tuesday, 46-year-old mum-of-three Rebecca Walker became the 61st Australian woman lost to violence in 2020. It is believed Rebecca's partner murdered her in what has been described as a "vengeful domestic-violence attack". The man who killed Rebecca - and then himself - was her partner and the father of her youngest child. When I think about Rebecca's death, I see her pyjama-clad five-year-old son wandering the streets of Townville looking for someone to help his mum after she was so grossly and selfishly deprived of her life. No one can possibly put into words better the reality of this atrocious act of violence than Rebecca's sister Samantha.
