Case 100

The Beaumont Children

*** Content Warning: child victims, child sexual assault, incest ***

On January 26 1966, siblings Jane, Arna and Grant Beaumont joined the hundreds of Adelaide residents who flocked to Glenelg beach to find respite from the scorching summer heat. It was a trip they’d made on their own many times before, and as usual, their mother Nancy sent them off with just enough money to buy bus fare and lunch from the bakery. 

However, panic kicked in when the Beaumont children failed to return home. Their disappearance sparked one of South Australia’s longest-running criminal investigations and changed the Australian way of life forever.
