This true crime episode covers the case of Becky Godden Edwards, a young heroin addict and sex worker who went missing in 2003 but wasn't found until 2011 when serial killer Christopher Halliwell confessed to her murder after being arrested for killing Sian O'Callaghan. The episode traces Becky's troubled childhood including bullying, self-harm, and drug addiction, while exploring the legal loophole that nearly prevented Halliwell's confession from being used as evidence.
