South Australian police have announced that they will be excavating a new area of the Castalloy factory in North Plympton in what they believe is a major development in the search for the missing Beaumont children.
Jane, 9, Arnna, 7, and Grant, 4, disappeared from Glenelg Beach on January 26, 1966 in a case that has remained unsolved for more than 50 years.
Reflecting on his childhood in SA, Luke Darcy told The Hot Breakfast his experience with the well-known case.
"When a story comes through about the Beaumont children the hair stands up on the back of my neck," Darce said.
"Obviously growing up in South Australia, this was always something that was in your awareness."
Darce then spoke of a terrifying encounter he had when he was young.
"As a 10-year old, I was walking home with my then-younger sister who was 2 or 3," he started.
"We'd been up to a friend's swimming pool up the road and we were confronted by a man who looked like they were disturbed.
"They got in front of me and my little sister - and I tried to pick her up and run with her because the guy was sort of agitating towards me.
"A lady saw it from across the street and jumped in front of the guy - and he's picked up and thrown her across the street in a way I'll never forget.
"And then as I was trying to run into my house the guy was saying 'you're the missing Beaumont children, you're the missing Beaumont children!'
"To this day it still sends a shiver up my spine.
"I got to the front door and my Mum at that stage could see there was an agitated man at the door.
"He then threw her out of the way and ran into the house and then away he went.
"But I was a 10-year old - the mention of the Beaumont children and what that meant to people in South Australia and that they were never discovered and that story never had a conclusion is something that still resonates to this day."
7 News reporter Michael Usher joined the show after to explain the latest developments in the case.
