Summary

Written by a model from the transcript; not yet reviewed.

This episode examines the October 1992 disappearance of 12-year-old Rhianna Barreau from her home in Morphett Vale, Adelaide. Host Gemma Bath and journalist Rebecca Bryce discuss how Rhianna returned safely from a local newsagent with a Christmas postcard before vanishing, leaving her front door locked with the television on. The investigation was hampered by competing police resources during massive Adelaide floods and an overwhelming influx of unverified tips, while leads involving a suspicious white Torana and a set of mysteriously reported keys ultimately led nowhere. Former lead detective Alan Arthur maintains that the offender and Rhianna's remains are likely located very close to her home, comparing the unresolved tragedy to the Beaumont children mystery. Despite a current one-million-dollar reward and an offer of immunity for an informant, the case remains unsolved, haunting the community and the journalist who revisited it decades later.

  • Keep in mind that police investigating the 1992 case faced extreme challenges while simultaneously dealing with massive floods at the other end of Adelaide. 11:53
  • Note that investigators considered potential links to Victoria's Mr. Cruel cases after a witness reported a white Torana with Victorian plates. 17:56
  • Understand that retired detective Alan Arthur strongly believes the offender lived extremely close to the victim's house. 22:50
  • Remember that South Australian Police offer a one-million-dollar reward and immunity from prosecution for the breakthrough that resolves the case. 0:11

About this episode

In October 1992, 12-year-old Rhianna Barreau disappeared. On the day she went missing it was school holidays, and Rhianna had spent the morning wandering to the local shops to buy her American pen pal a Christmas card. When her mother got home at 4pm, expecting to find Rhianna, she was nowhere to be found. It's one of South Australia's most enduring cold cases. Her disappearance didn’t just change the lives of her family, it changed her community and the streets of Adelaide forever.
