In 1998, Marion Barter liquidated her life. She sold her house, told her family she was traveling the world, and walked away from everything—and everyone. Nearly three decades later, Marion has never been seen again. Her daughter Sally Leydon has spent the last 25 years trying to find her, turning frustration with official investigations into a multimedia crusade that has captivated millions.

The circumstances of Marion's disappearance remain deeply troubling. At age 51, she had settled her affairs with unusual haste and finality, as if preparing not for travel but for erasure. Around the time she vanished, a man appeared in her life: someone identifying himself as "Mr. Blum," later known as Rick Blum. This man used 14 different aliases—a red flag that authorities somehow failed to fully investigate.

The timeline is unsettling. In May 1994, Blum had placed a personal ad in a newspaper claiming to be 47 years old, from the same location as Marion. The overlap in geography, the coordinated age proximity, and his pattern of assumed identities form a suspicious constellation. Yet Blum has consistently denied involvement in Marion's disappearance.

Evidence uncovered over the years paints an increasingly damning picture: a love letter, a substantial bank transfer, a last-minute name change, mysterious Medicare alerts, and unexplained bank withdrawals. These fragments suggest a relationship—possibly coercive, possibly dangerous—but they proved insufficient to satisfy official investigations, which Leydon describes as marked by significant failings.

A coronial inquest held before February 2024 offered little closure. When findings were delivered on February 29, 2024, Sally found herself with more questions than answers. The formal investigation had ended without resolving her mother's fate. That outcome crystallized her determination to pursue the case herself.
