After Decades of Silence, a Shocking Arrest Revives a 2002 South Australia Cold Case
South Australia 2002 Cold Case Cracked After 24 Years—The Arrest No One Expected
The Backyard Horror: 23 Years of Secrets Finally Unearthed
The quiet coastal town of Port Lincoln, South Australia, is known for its serene beauty, where the water of Boston Bay meets the horizon and neighbors look out for one another. But beneath the tranquil surface of Ma Crescent, a nightmare was buried—literally. For twenty-three long years, the disappearance of 39-year-old Susan Goodwin remained a haunting stain on the community. For two decades, investigators, search teams, and grieving family members scoured 25 square kilometers of dense scrubland and rugged coastline, desperate to find a woman who had seemingly vanished into thin air on a routine Friday afternoon in July 2002.
They were looking everywhere—everywhere except the one place that mattered.
It wasn’t until September 2025 that modern forensic advancements finally pierced the veil of this decades-long mystery. When detectives returned to the scene with new intelligence and ground-penetrating radar, they didn’t head for the remote wilderness. They turned their attention to a residential property on Premier Court, the street running directly behind Susan’s own home. In a revelation that has shocked the nation, the remains of Susan Goodwin were discovered beneath the backyard of her own next-door neighbor. She had been less than 50 meters from her own kitchen, mere steps away from the life she was living, while the world searched for her in the wrong direction for nearly a quarter of a century.
A Life Marked by Tragedy
Susan Goodwin’s life was defined by a resilience that few can comprehend. Born in 1962 in Bairnsdale, Victoria, she was a vibrant soul deeply connected to her family. But tragedy struck in September 1984, when a devastating car accident on Clifton Creek Road claimed the lives of three of her siblings. Susan, miraculously, was one of the few who walked away. The psychological weight of that loss never truly faded; she spent the following years drifting along the Victorian coast, seeking solace in the ocean, eventually finding a sense of peace in the quiet fishing town of Port Lincoln in the mid-1990s.
She settled into a life of simplicity with her partner, Michelle Peterson. Susan loved fishing off the jetties, playing pool, and enjoying quiet evenings at home. She had finally found a rhythm, a place 2,000 kilometers from the trauma of her past. Then, on July 19, 2002, that rhythm was shattered.
Susan went shopping for groceries—fresh meat for dinner, staples for the week. She was seen at home that day, visibly distressed, though the reason remains an enigma. By 4:15 PM, when she was supposed to pick up Michelle from the tuna processing plant, she was gone. Her car sat locked in the driveway, her toothbrush remained on the bathroom shelf, and dinner sat untouched in the fridge. It was as if she had stepped out for a moment and never returned.
The Coldest Case of the Peninsula
The investigation that followed was nothing short of monumental. Port Lincoln’s State Emergency Service volunteers walked grid lines for days, combing through the coastal vegetation. Police utilized every resource, naming seven persons of interest and questioning them relentlessly. They plastered her face on drink coasters in local pubs and wrapped police cruisers in her photograph, turning every passing patrol car into a mobile memorial for a woman the town refused to forget.
Yet, for 23 years, the trail went ice cold. The Goodwin family, particularly her parents Dawn and Margaret, lived in a state of suspended animation. They aged, they suffered, and they eventually passed away in 2017—brokenhearted, never knowing what had happened to their “Suzy.” Her father even recorded a video plea in his final days, begging for the truth so he could die in peace. He never got that answer.
The Breakthrough
The breakthrough, when it finally arrived, was a testament to the relentless pursuit of justice. By 2023, forensic technology had evolved to a point where the evidence collected in 2002—which had sat in a box at the Major Crime investigation unit in Adelaide for two decades—could finally be analyzed with groundbreaking accuracy. The results narrowed the suspect pool to one person: John Mislov, the man who had owned the Premier Court property in 2002.
The arrest of Mislov in September 2025 sent shockwaves through South Australia. He had been living in Port Lincoln the entire time, his name never once appearing on the original, exhaustive list of persons of interest. He had literally been the neighbor looking over the fence while the police searched the wilderness. In the wake of his arrest, reports emerged that Mislov had made admissions to police—details that currently remain sealed under court order as the community braces for trial.
As of April 2026, the legal process is underway. For the survivors of the Goodwin family, the discovery provides a devastating sense of closure. Susan, who had survived the loss of her siblings and the trials of life, was waiting to be found in the most heartbreakingly proximal location imaginable. Her final resting place will now be in Port Lincoln, the town she chose to call home, far from the scrubland where she was so desperately—and so wrongly—sought. The mystery of the “backyard grave” stands as a grim reminder that sometimes, the most profound secrets are hidden in plain sight.
