Watch Wrongly Released

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.

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.
