Two years ago Detective Inspector Glen Brown established the NSW Police Missing Persons Registry, revolutionising the way police investigate missing persons cases. I speak to Glen about the stunning success of the Registry, and how police are now not only finding people who disappear faster, but also saving the lives of people who are vulnerable by using the latest technologies to locate them before it's too late.

Please note: this is an older episode of The Missing from a few years ago. The audio quality is better in series 2 (from June 2023), but the content and story is just as important.
