A Triple Murder And A Broken System

In May 2016, police arrived at a farmhouse in Hillier, north of Adelaide. The scene that awaited them was horrifying beyond words.

Stephen Graham Peet had just murdered three people. The bodies of his girlfriend, Adeline Yvette Rigney-Wilson, and her two young children were inside.

But as his crimes unravelled in court, something became clear. Those two little kids shouldn’t have died. Their deaths, at least, were preventable. It was a series of failures from government agencies designed to protect them that actually, left them in the path of a killer.
