Wrongly Released

In September 2012, Melbourne was rocked by the news of the murder of Jill Meagher. The response to her death resulted in a public outcry demanding that the Victorian parole system be investigated. But the subsequent inquiry came too late for 22-year-old Sarah Cafferkey - killed by serial offender Steven Hunter - a man who had murdered another young woman 26 years before.

In January 2006, two sisters Collen and Laura Irwin were raped and murdered in the unit they shared in Altona North. Initially police were at a loss to identify a suspect, until a local factory owner reported an employee missing - an employee who harboured a sinister past.
