In 2003, convicted child killer Leonard John Fraser was back before court accused of murdering three women and a teenager.

But his trial was about to become international news for the most bizarre reason: one of the victims had just come back to life.

Soon everyone would know about Natasha Ryan, the girl who hid from the world for five years as her parents and friends mourned her 'death'.

In this episode, criminologist Dr Wayne Petherick also explains the traits of a psychopath and we examine how the law failed Fraser's victims.
