In this episode of Real Crime with Adam Shand, we sit down with Steve Van Aperen — Australia’s leading polygraph examiner, widely known as the “Human Lie Detector.” After 15 years in the police force, Steve built a career uncovering deception in homicide investigations, cold cases and even everyday disputes. Adam and Steve explore the power and limits of polygraphs, the rise of new lie-detection technologies and the psychology of interrogation. Along the way, they revisit infamous cases like the Beaumont children disappearance and the chilling murder of Bonnie Clarke, while asking: how much should we really trust lie detection in the pursuit of justice?
