In 2015 Elle Underhill, four, and her sister Elaina, two, were taken for a drive by their 18-year-old babysitter in their home town of Casino in northern New South Wales.
Their parents were at home having lunch, and were startled by the sounds of police sirens whizzing past their house.
Steve Underhill, the girls’ father, is a police officer himself and was immediately unsettled.
“I was thinking to myself, that’s not good. Knowing full well what screaming sirens usually mean,” he told A Current Affair.
Here is a clip from the A Current Affair story. Post continues after video.
Michelle Underhill’s immediate reaction went one step further.
“Call it a mothers instinct – I just had a horrible, gut-wrenching feeling it was the girls,” she told the program.
Their fears were confirmed when they saw someone post a photo of Mrs Underhill’s Mazda on social media – the car involved in the crash.
Courteney Matthews , the babysitter, had lost control and collided with a car travelling in the other direction. The force ripped the Mazda in two.
“I just remember the shards of glass piercing my feet as I just ran, ran to the middle, I sat down in front of half a car,” Mrs Underhill said.
