A long standing theory, but one ballistics supports, at least in the mind of some of those who worked the case, is that Ivan Milat didn't act alone and that there were multiple shooters at several of his crime scenes.

Host Kathryn Fox sits down with one of Australia's most respected forensic experts, Gerard Dutton to understand why some think there was more than one shooter, and how specific ballistic evidence supports this.

A group of bikies converged on Sydney airport. Within minutes, one was dead and others injured. It was an incident that set off one of the world's most intense and effective gang operations, and led to a plethora of law changes and high profile convictions.

Deborah Wallace is a titan of NSW Police. Retiring in 2019 after 36 years in the force, she became known across Australia as 'The Gangbuster', after successful operations in the intense region of Cabramatta, and then the aforementioned Strike Force Raptor.

The beginning of her career though was much more abstract. She was involved in one of Australia's most horrific cases. The rape and murder of Anita Cobby in 1986.

Understand the impact of that case on Deb, and Australia as a whole as Brent Sanders steps through the career of one of Australia's most decorated police officers.

Without the internet, police were unable to track offender behaviour, and heavily relied on the testimony of victim-survivors.

These interviews were crucial, and required care and empathy, as one misstep, and evidence could be lost and a victim survivor left unheard.

Former detective Andrew Patterson was part of a special task force investigating paedophiles in Perth, and was the one who spoke to hundreds of victim-survivors... One morning, he received information about a sexual predator, and descriptions of an underground chamber with shiny chrome walls. He and his team set about investigating the offender, and finding survivors.

Andrew sat down with host Brent Sanders to explain this case, and others from his impressive career.
