The Missing Matter: Investigating Decades of Disappearances

Sally Leydon's podcast The Missing Matter uses personal storytelling and investigative rigor to examine cases of people who vanished without answers. Available on Apple Podcasts, the series has garnered strong listener engagement with a 4.7/5 rating across 38 reviews in the US, establishing itself as a significant voice in true crime journalism focused on ambiguous loss and family resilience.

The podcast's anchor case is the disappearance of Marion Barter, an award-winning Australian schoolteacher who vanished in 1997 while traveling through Europe. Nearly 27 years later, Marion's case remains unresolved despite a coronial inquest concluded on 29 February 2024 that raised more questions than answers. Leydon, Marion's daughter, partners with investigative journalist Joni Condos to retrace her mother's final steps across multiple continents—from Australia through Japan, London, Amsterdam, Brussels, Luxembourg, and Lille. The investigation employs unconventional techniques including scent-tracking dogs and examines cash-trail anomalies and legal briefs that may hold clues to Marion's fate.

The ad-free first episode, "So Close, Yet So Far," was released on 12 May 2025 and marks the beginning of what Leydon describes as "The Next Chapter in the Search for Marion Barter." The episode delves into the aftermath of the 2024 inquest and the family's determination to uncover what official investigations could not.

Season 3, launching Monday, 9 February 2026, expands the podcast's scope to additional unresolved cases, including the 2012 disappearance of Sandrine Jourdan. The 37-year-old mother of three vanished on Friday, 13 July 2012, from a property in Caboolture, north of Brisbane. Now 4,946 days missing, Sandrine's case remains among Australia's most haunting unsolved disappearances. Her youngest daughter, Nikita, shares memories and questions the official narrative surrounding her mother's vanishing, offering listeners intimate family perspectives often absent from conventional true crime coverage.

Another featured case involves Ray and Jennie Kehlet, who disappeared in March 2015 during a prospecting trip in remote Western Australia. Days after their vanishing, Ray's body was discovered at the bottom of a mine shaft; a coronial inquest ruled his death a murder, yet no charges were filed. Jennie was never found. The podcast examines nine years of evidence and documented missed investigative opportunities, highlighting systemic failures that compound the families' suffering.

The series also addresses the case of Andrew Inglis, who disappeared in 1985 from Yamba caravan park in northern New South Wales at just 18 years old. Nearly 40 years later, his family remains in limbo—no search was conducted, no inquest held, and no public appeal was ever launched. By bringing Andrew's story to listeners, Leydon's podcast serves as a form of advocacy for forgotten cases.

Beyond individual episodes, The Missing Matter distinguishes itself through Season 2's conversations with families of the missing, offering a platform for voices typically marginalized in mainstream media. The podcast acknowledges the psychological phenomenon of ambiguous loss—the profound grief experienced when a loved one's fate remains unknown—while combining this empathetic framework with rigorous investigative journalism.

Available through Apple Podcasts and via themissingmatter.com, The Missing Matter represents a significant contribution to international true crime discourse, particularly in centering the experiences of families and pursuing investigative leads that official channels may have abandoned.
