They deserve for people to know their names. They shouldn't just be someone's victim.

Their dash and violence were celebrated, and men like Ray Denning and Russell 'Mad Dog' Cox were household names long before Underbelly established Melbourne's gangland thugs as celebrities. Both were handsome, charismatic bandits who refused to bow to authority. Both were classified as 'intractable' in prison, and both escaped. Cox was the only man to escape from Katingal, Australia's only 'escape-proof' jail. Soon after he broke out, he tried to break in again and rescue his mates.

He was a chameleon with a modus operandi refined over the decades, luring young teenage girls with the promise of a career as a photographic model.

Carl Williams' role as unlikely gang boss in the Melbourne Gangland Wars had made him one of the most infamous names in Australian criminal history. In 2007 he was sentenced to 35 years' jail in a high security unit.
