The Story

On Australia Day 1966, Jane, Arnna, and Grant Beaumont took a bus to Glenelg Beach near Adelaide—a trip they had made before. They were seen playing with a tall blond man and buying snacks. None of the three returned home. The case transformed Australian parenting and remains the nation's most famous child disappearance.
