Within a few days, Shanon and Khloe Heidemann lost both their parents and their little brother in two separate, tragic accidents.
The teenagers’ father, David Heidemann, 50, was last seen on March 31 after leaving his home in Mondure, Queensland, and disappearing in the havoc wreaked by Cyclone Debbie, according to Nine News.
Shanon, 17, was helping search for him in floodwaters when his mother’s car collided with a truck at Berry, on the New South Wales South Coast on April 4.

Jane Towers, 39, and her 12-year-old son Jayjay died, while 14-year-old Khloe was hospitalised with critical injuries.
She remains comatose in The Children’s Hospital, Westmead, with two fractured legs, a fractured arm, shattered pelvis and brain swelling.
Just four days after the car accident, David's body was found in Barambah Creek by Queensland Police.
