Decades since his three children disappeared, Grant Alfred Beaumont has passed away at the age of 97, marking another chapter in one of Australia’s most enduring cold cases.

A funeral notice announced his passing, claiming that he had now been “reunited in heaven” with his three beloved children.

“Loved father of Jane, Arnna and Grant,” the notice read.

Nancy, his wife, passed away in 2019 at the age of 92 while residing in a nursing home, after being separated from Grant.

Regrettably, Grant and his wife never had the chance to discover the fate of their three children who went missing on an Adelaide beach 57 years ago.

The missing Beaumont children is one of Australia’s most infamous unsolved mysteries. On January 26, 1966, three siblings – Jane, Arnna, and Grant Beaumont – went missing from Glenelg Beach, South Australia. The children, aged 9, 7, and 4 respectively, had gone to the beach for the day and were last seen playing on the foreshore near the beach’s kiosk. Despite a massive search effort, the children were never found, and their disappearance remains a mystery to this day.

The Beaumont case is notable for its impact on Australian society and law enforcement. At the time, it was the largest search operation ever mounted in Australia, and it captivated the nation’s attention for months. The case led to changes in police procedures and sparked a national conversation about child safety, with many parents becoming more vigilant about their children’s whereabouts.

Over the years, there have been many theories about what happened to the Beaumont children. Some believe they were abducted by a stranger or group of strangers, while others speculate that they may have been victims of a serial killer. Despite numerous investigations and leads over the years, no definitive evidence has ever been found to solve the case. However, the case has remained in the public consciousness, and it continues to be studied and investigated by law enforcement and researchers to this day.

It remains one of the most haunting mysteries in Australia’s history, and its impact is likely to be felt for many years to come. Even after several decades, the case still attracts regular media coverage, as new leads and clues are reported.

Despite numerous searches and the offer of a $1 million reward for information related to the case by the South Australian Government, neither the children nor their alleged abductor has ever been located and the disappearance remains a mystery.
