On the morning of January 26, 1966, the streets of Adelaide were alive with the relaxed, cheerful energy of Australia Day. Families gathered to celebrate, and children played freely in the summer sun. For Jim and Nancy Beaumont, it was like any other holiday. Their three children—Jane, 9, Arnna, 7, and Grant, 4—set off for a fun-filled day at Glenelg Beach, a favorite local spot. The siblings were excited for the short bus ride from their Somerton Park home, a journey they had made many times before. Jane, the eldest, was responsible and mature beyond her years, often looking after her younger siblings with care. The Beaumonts had no reason to worry. It was a time when communities felt safe, and parents trusted their children could explore the world around them without harm.
The day promised sunshine, sand, laughter, and the kind of freedom every child enjoys during the summer. But by nightfall, this seemingly ordinary outing would unravel into one of Australia's most chilling and enduring unsolved mysteries, leaving a scar on the hearts of a nation for decades to come.
